DESCRIPTION OF THE PREFERRED EMBODIMENTS

(8) The present invention will be described in detail below in combination with specific embodiments.

(9) FIG. 2 is a structural diagram for an embodiment of the present application.

(10) The labor-saving connection structure of the embodiment comprises a first connection portion 1 and a second connection portion 2. The first connection portion 1 and the second connection portion 2 are intercoupled, and an auxiliary closing mechanism 3 is further arranged on the first connection portion 1. When the first connection portion 1 is coupled with the second connection portion 2, the auxiliary closing mechanism 3 is snapped in the second connection portion 3, and drives the first connection portion 1 and the second connection portion 3 to move toward each other to realize coupling connection.

(11) Refer to FIG. 2, the auxiliary closing mechanism 3 comprises a grip 31 and a lever force applying plate 32. Both sides of the lever force applying plate 32 are pivotably connected with the end of the grip 31. The end of the lever force applying plate 32 is pivotably connected with the end of the first connection portion 1 by bolts (or pins or buckles). The grip 31 is connected with an upper surface of the second connection portion 2 during the coupling connection between the first connection portion 1 and the second connection portion 2, as shown in FIG. 3. The lever force applying plate 32 pushes the first connection portion 1, and the first connection portion 1 and the second connection portion 2 move toward each other to realize the coupling connection therebetween, which is convenient and labor-saving.

(12) The detailed structure of the auxiliary closing mechanism 3 is shown in FIG. 2 and FIG. 3. The grip 31 comprises a downwards protruded insertion strip 311 arranged at the top end and two fixed edges 312 extending backwards from both sides of the insertion strip 311. The insertion strip 311 is snapped in the upper surface of the second connection portion 2, and both sides of the lever force applying plate 32 are arranged between the two fixed edges 312 through bolts (or pins or buckles). The specific shape of the pull grip 31 is not limited, and it is only required to ensure that the grip 31 is provided with the insertion strip and the structure (fixed edges 312) in contact with the lever force applying plate.

(13) To further ensure that the auxiliary closing mechanism 3 is well connected on the upper surface of the second connection portion 2, a plurality of convex-concave points or concave-convex strips are arranged on the contacting part between the insertion strip 311 and the upper surface of the second connection portion 2. In addition, a slot 21 or a convex strip matched with the insertion strip is arranged on the upper surface of the second connection portion 2. Sufficient mating force is provided during the coupling of the first connection portion 1 and the second connection portion 2 by snap connection between the slot 21 or convex strip and the insertion strip 311.

(14) In addition, to better utilize the lever force applying plate 32 and enable it to provide the maximum thrust pushing the first connection portion 1, the distance from insertion strip 311 to the contacting part between the lever force applying plate 32 and the fixed edges 312 is not be less than the distance from the contacting part between the lever force applying plate 32 and the fixed edge 312 to the end of the lever force applying plate 32.

(15) In the first embodiment, the first connection portion 1 and the second connection portion 2 are intercoupled in a socket joint mode. The first connection portion 1 and the second connection portion 2 are intercoupled plug and socket, respectively, as shown in FIG. 2 and FIG. 3 of the embodiment.

(16) As shown in FIG. 2, the plug (the first connection portion) and the socket (the second connection portion) insertion structure are common coupled structures. The socket is provided with a jack that has I-shaped cross-section. The plug is provided with an insertion tongue which is disconnected at the front end, and a concave slot is provided respectively at both sides of the insertion tongue. When the plug is inserted into the socket, the front end of the plug contracts inwards. After the tongue is inserted into the jack and passes through the middle portion of the jack, the tongue at both ends bounces outwards due to elastic force. The slot is in snap connection with the edge of the jack to prevent the tongue from falling out of the jack. The auxiliary closing mechanism 3 of the present application provides assistance when the tongue is inserted into the jack until elastic force recovers.

(17) The advantages of the application are simple structure, minor change to production process, and cost saving. It is not required to significantly change the structure of the plug and socket or change the existing production line of the plug. It is only necessary to add a process step after the end of the existing plug production process, that is, connecting the auxiliary closing mechanism of the present application to end of the plug by screws, which has low manufacturing cost.

(18) Of course, the first connection portion and the second connection portion of the present application are not limited to the structures of the plug and the socket and can be other connection structures.

(19) Furthermore, as shown in FIGS. 4 and 5, the present application also discloses a luggage binding strap, wherein the luggage binding strap comprises the labor-saving connection structure 4 and a strap body 5, and both ends of the strap body 5 are connected with the first connection portion 1 and the second connection portion 2 of the labor-saving connection structure 4, respectively. An adjusting mechanism is arranged on the strap body 5 to adjust length of the strap body 6.

(20) Thanks to the labor-saving connection structure, when the luggage 7 is strapped by the binding strap, the length of the binding strap can be properly adjusted in advance, so that the length of the binding strap plus the first connection portion 1 and the second connection portion 2 matches the luggage body 7. As shown in FIG. 6, the first connection portion 1 is aligned with the second connection portion 2. Since the strap body 5 is fastened to the luggage body, when the first connection portion 1 and the second connection portion 2 are coupled, it is laborious to push the first connection portion 1 into the second connection portion 2. At this time, as shown in FIG. 7, through the labor-saving connection structure, the grip is fixed to the upper surface of the second connection portion, and then the lever force applying plate is pushed to easily couple the first connection portion 1 and the second connection portion 2.

(21) Moreover, a transparent pocket for placing a nameplate can be arranged on the upper surface of the grip 31, so that the identity information of the luggage owner is displayed in the pocket after packing for identification.

(22) In addition, to facilitate the user to adjust the strap body, a marking line is set on the strap body to indicate the length of the strap body. The adjusting mechanism is at the double overlap of the strap body, since distance of every interval indicated on the marking line located near both ends of the first connection portion and the second connection portion is deliberately set to be twice the distance of every interval indicated on the marking line located near the adjustment mechanism.

(23) In summary, the labor-saving connection structure of the present application can easily complete the coupling action when the length of the strap body is properly adjusted, which is convenient and labor-saving.

(24) It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. In addition, it should be understood that various changes and modifications can be made to the present invention by those skilled in the art after they read the present invention. These equivalent forms will also fall into the protection scope as defined by the appended claims of the present application.
