DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Embodiment 1

[0024] As shown in FIG. 1 and FIGS. 3-6, a child's safety belt connection buckle comprises, an inserting base 1 with an inserting space and a belt buckle 9, the belt buckle 9 is formed by fixedly connecting an upper inserting base cover and a lower inserting base cover each other. The belt buckle 9 is inserted into the inserting space along the horizontal direction and locked by means of a locking mechanism.

[0025] In the figures of this embodiment, the inserting base 1 has a base 2 therein, and the inserting space is formed on the base 2.

[0026] The locking mechanism comprises a sliding member 3 arranged on the inserting base 1 capable of moving reciprocally along the horizontal direction, and a locking member 5 arranged on the inserting base 1 capable of moving reciprocally in a direction perpendicular to the horizontal direction.

[0027] There is one sliding member 3, and there may be one or two belt buckle(s), for example when being used for the safety belt of a car seat, there is just one belt buckle; and if being used for the safety belt of a child seat, there may be two belt buckles, and in this embodiment, there are two belt buckles.

[0028] The locking mechanism has a locking position and an unlocking position. When the locking mechanism is at the locking position, the belt buckle 9 is pressed against the sliding member 3, that is to say, the locking member 5 is able to be buckled with the belt buckle 9, respectively. When the locking mechanism is at the unlocking position, the locking member 5 is separated from the belt buckle 9 and pressed against the sliding member 3.

[0029] An elastic restoring member 4 is provided between the sliding member 3 and the inserting base 1 such that the sliding member 3 has a trend to move towards the belt buckle 9. When the belt buckle 9 is inserted into the inserting space, it is needed to overcome the elastic force of the elastic restoring member 4. When the belt buckle 9 is drawn out from the inserting space, the sliding member 3 is reset by the elastic force of the elastic restoring member 4. An elastic member 6 is provided between the locking member 5 and the inserting base 1 such that the locking member 5 has a trend to move towards the sliding member 3 or the belt buckle 9. When the locking mechanism is at the locking position, the sliding member 6 makes the locking member 5 to be stably buckled with the belt buckle 9. When the locking mechanism is at the unlocking position, the sliding member 6 makes the locking member 5 to be stably pressed against the sliding member 3.

[0030] The elastic member 6 is a spring leaf, one end of the elastic member 6 is connected with the inserting base 1, and another end of the elastic member 6 is connected with the locking member 5. This results that the size of the inserting base 1 in the direction vertical to the horizontal direction is relatively thin.

[0031] An unlocking control mechanism is provided on the inserting base 1 to control the unlocking of the locking mechanism, and the unlocking control mechanism comprises an unlocking button 7 slidably provided on the inserting base 1 along the horizontal direction, and a button elastic element 8 provided between the unlocking button 7 and the inserting base 1 to make the unlocking button 7 move outwards to reset, an inclined guide slope 71 is on the unlocking button 7, a guide column 52 is on the locking member 5, and the guide column 52 is pressed on the guide slope 71. A button space is on the inserting base 1, within which the unlocking button 7 and the button elastic element 8 are located.

[0032] The base 2 is made of metal material, and comprises an upper base sheet 21 and a lower base sheet 22 assembled together, the inserting space is formed between the upper base sheet 21 and the lower base sheet 22, and the sliding member 3 is located within the inserting space. The lower base sheet 22 comprises a horizontal portion, and an upright portion vertical to the horizontal portion and extending from two sides of the horizontal portion upwardly. An accommodating groove is provided on the horizontal portion for accommodating the sliding member 3, and a sliding groove is provided on the upright portion for supporting the locking member 5 to slide. The sliding direction of the sliding member 3 in the accommodating groove and the sliding direction of the locking member 5 in the sliding groove are vertical to each other.

[0033] The locking member 5 is partly inserted into the inserting space when at the locking position. Specifically, a locking portion 51 is provided on the locking member 5, and a locking slot 91 matching with the locking portion 51 is provided on the belt buckle 5.

[0034] When the belt buckle 9 is inserted into the inserting space, the belt buckle 9 is pressed against the sliding member 3 to move, the locking portion 51 of the locking member 5 is inserted into the locking slot 91 of the belt buckle 9, and the unlocking button 7 is pushed outwardly by the button elastic member 8, to achieve the lock of the safety belt connection buckle, that is to say, the safety belt connection buckle is locked by the locking mechanism. During unlocking, the elastic force of the button elastic member 8 is overcame by pressing the unlocking button 7, the guide slope 71 pushes the guide column 52 to drive the locking member 5 upwardly, that is to say, under the cooperation of the guide slope 71 and the guide column 52, the locking member 5 is lifted upwardly such that the locking portion 51 and the locking slot 91 are separated from each other, the sliding member 3 is reset in the horizontal direction under the action of the elastic restoring member 4, and at this moment, the locking member 5 is pushed against the sliding member 3.

Embodiment 2

[0035] As shown in FIGS. 2 and 7, Embodiment 2 is mainly distinguished from Embodiment 1 by that there are two sliding members 3, and correspondingly, two elastic restoring members 4. Moreover, the two sliding members 3 correspond to the two belt buckles 9, respectively.

[0036] When any one of the two belt buckles 9 is inserted into the inserting space, only one sliding member 3 is pushed to move and the other one does not move, the locking member 5 cannot slide down, such that the locking mechanism cannot lock. When both the two belt buckles 9 are inserted into the inserting space, both the two sliding member 3 are pushed to move, the locking member 5 slides down, and the locking mechanism locks and is safely used. Similarly, during unlocking, the elastic force of the button elastic member 8 is overcome by pressing the unlocking button 7, and under the cooperation of the guide slope 71 and the guide column 52, the locking member 5 is lifted upwardly, and the belt buckles 9 are pushed outwardly under the action of the elastic restoring member 4 and sliding member 3. When releasing the unlocking button 7, the locking member 5 is pushed against the sliding member 3 under the action of the button elastic member 8.

[0037] The embodiments described above are only for illustrating the technical concepts and features of the present invention, and intended to make those skilled in the art being able to understand the present invention and thereby implement it, and should not be concluded to limit the protective scope of this invention. Any equivalent variations or modifications according to the spirit of the present invention should be covered by the protective scope of the present invention.
