DETAILED DESCRIPTION OF THE INVENTION
(12) For a better understanding of the invention, the invention is expounded below with reference to embodiments. The following embodiments are used to explain the invention, but are not intended to limit the scope of the invention.
(13) As shown in FIGS. 1-3, the invention relates to a dip net provided with a lockable and foldable handle. The dip net comprises a handle 1, a hoop 3 and a hoop mounting base 2. The hoop mounting base 2 is fixed to the front end of the handle 1. The hoop mounting base 2 is fixed to the handle 1 or is detachably connected to the handle 1 in a threaded manner (not shown). The outer side of the handle 1 is wrapped with an outer ferrule 11 which is made from a buoyant material. A plurality of anti-slip pits 12 are formed in the surface of the outer ferrule 11. The handle 1 can be held more comfortably by means of the outer ferrule 11. Meanwhile, the outer ferrule 11 is made from a buoyant material, so that when accidentally falling into water, the dip net can float up to be fished conveniently. The anti-slip pits 12 in the surface of the outer ferrule 11 can improve the friction between the handle and the hand, so that the dip net is unlikely to slip out of the hand. A strap 13 is fixed to the rear end of the handle 1, and users can hang the dip net on their shoulders by means of the strap 13.
(14) As shown in FIGS. 4-6, the hoop mounting base 2 comprises a base body 21, a rotary shaft 25 and a lock device, wherein the lock device comprises a spring 22, a lock catch 23 and a buckle 24, and the base body 21 is provided with a buckle sliding groove 28. The buckle 24 and the spring 22 are both mounted in the base body 21. The buckle 24 is provided with a through hole 231 which vertically penetrates through the buckle 24. A round hole 232 is formed in the rear end of the buckle 24. The diameter of the spring 22 is slightly smaller than that of the round hole 232, the front half portion of the spring 22 extends into the round hole 232 and is in close contact with the buckle 24, and a protrusion is arranged at the front end of the buckle 24. An end cover 20 is arranged at the front end of the base body 21, is connected with the base body 21 in a buckled manner, and has a sealing effect, so that water is prevented from entering the hoop mounting base during fish scooping, which may otherwise cause rusting of the spring and the rotary shaft in the hoop mounting base under a humid condition; and the quality of the spring and the rotary shaft is guaranteed, locking is facilitated, and the service life of the dip net is prolonged.
(15) As shown in FIGS. 4-6, the buckle 24 is mounted in the buckle sliding groove 28 and is connected with the base body 21 in a manner of sliding forwards or backwards. A pin 241 is arranged in the buckle 24 and is inserted into the through hole 231, so that the buckle 24 and the lock catch 23 are connected into a whole and are fixed together. A plurality of concave-convex grooves 242 are formed in the surface of the buckle 24 and are used for increasing the friction between the hand and the buckle 24 when the buckle 24 is pulled by hand, and thus, the buckle 24 can be conveniently pulled by users.
(16) As shown in FIGS. 4-6, the rotary shaft 25 is mounted in the base body 21, and a shaft seat can rotate around the rotary shaft 25 if not restrained. As shown in FIGS. 7-9, the rotary shaft 25 is provided with at least two clamping grooves 30 in a circumferential direction. For instance, in this embodiment, the rotary shaft 25 is provided with two clamping grooves 30, and an included angle between the two clamping grooves 30 is 180°; when the hoop 3 and the handle 1 are totally unfolded, one clamping groove 30 is matched with the protrusion 29; when the hoop 3 and the handle 1 are totally folded, the other clamping groove 30 is matched with the protrusion 29; and after the protrusion 29 is inserted into any one of the two clamping grooves 30, the spring 22 pushes the buckle 23 forwards, and then the rotary shaft 25 is locked by the protrusion 29 and cannot rotate anymore.
(17) As an example, the rotary shaft is provided with two clamping grooves 30 in this embodiment. In actual implementation, the rotary shaft can be provided with a plurality of clamping grooves 30, so that the angle between the hoop 3 and the handle 1 can be changed according to the height of fishermen and the distance to fish, and then the overall length of the dip net is changed to achieve a better fish scooping effect.
(18) When the dip net provided with the lockable and foldable handle is transported or carried, the handle 1 and the hoop 3 are folded into a structure shown in FIG. 10, and the handle 1 is entirely folded into the space defined by the hoop 3 to reduce the size of the whole dip net, so that the dip net can be carried conveniently; at this moment, the spring 22 abuts against the buckle 23, and the protrusion 29 at the front end of the buckle 23 is just clamped in one clamping groove 30 of the rotary shaft 25, so that the rotary shaft 25 is restrained by the buckle 23 and cannot rotate, collision to the dip net caused by random rotation of the handle 1 and the hoop 3 during carrying is avoided, and the dip net can be carried conveniently. When the dip net is about to be used for scooping fish, the buckle 24 is pulled backwards by hand and then drives the lock catch 23 to move backwards to compress the spring 22, the rotary shaft 25 is not retrained by the protrusion 29 anymore, at this moment, the handle 1 is rotated to be unfolded, and the buckle 24 is released; and when the other clamping groove 30 of the rotary shaft 25 rotates to be aligned to the protrusion 29, the spring 22 restores to the original length and pushes the lock catch 23 to move forwards, then the protrusion 29 is inserted into the clamping groove 30 to lock the rotary shaft 25, the hoop 3 cannot rotate anymore, and the stability of the dip net is guaranteed when the dip net is used for scooping fish.
(19) The present invention is expounded above with reference to embodiments, but these embodiments are only preferred ones of the invention and are not intended to limit the implementation scope of the invention. Any variations and improvements achieved within the application range of the invention should also under the patent coverage of the invention.
