Referring to fig. 1 to 5, the present embodiment provides a detachable bow, which includes a handle 10 and two bow arms 20, wherein the two bow arms 20 are symmetrically disposed on two ends of the handle 10, and the tail ends of the two bow arms 20 are connected to form a bow string 30. The two ends of the handle 10 are symmetrically provided with inserting grooves 101, the connecting end of the bow arm 20 is provided with an elastic clamping piece 201, and the inner side surface of the inserting groove 101 is provided with a clamping groove 1011 which is embedded with the elastic clamping piece 201.

In this embodiment, the engagement between the engaging slot 1011 and the elastic clip 201 is adopted, so that the bow arm 20 can be quickly detached and mounted on the handle 10. Specifically, the elastic force of the elastic clamping piece 201 can be propped against the clamping groove 1011, so that the effect of inserting and fixing the bow arm 20 is realized; when the detachable bow needs to be detached, the bow arm 20 can be directly pulled out by utilizing the elastic force of the elastic clamping piece 201, and the purpose of rapidly detaching and assembling the detachable bow is realized.

Before use, the bow arms 20 are respectively inserted into the insertion grooves 101 at the two ends of the handle 10 in an insertion manner, and then the upper bowstring 30 is fixed on the bow arms 20 to form a detachable bow. If the bow arm 20 is reversely bent, the bow and arrow are reversely bent. By utilizing the structural design of the elastic clamping piece 201 and the design of the insertion groove 101 and the clamping groove 1011 on the handle 10, the detachable bow has the effect of quick detachment and installation. Meanwhile, through the design of the elastic clamping piece 201, the bending or tearing type damage or damage is not easy to occur, so that the service life of the detachable bow is correspondingly prolonged.

Further, as shown in fig. 4 and 5, in this embodiment, the elastic clip 201 is a spring plunger, the locking slot 1011 is embedded with the spring plunger, the cylindrical groove of the locking slot 1011 can accommodate a positioning ball of the spring spider plunger, and the ball head of the spring plunger can be used to achieve the effect of inserting and pulling out the bow arm 20. The spring plunger is also called a ball plunger or a positioning ball/column, and a spring is arranged in the screw thread. The beads or pins in the product set with pre-pressure and move up and down. The spring ball plunger should have accurate end face pressure, use long high-quality spring as far as possible by reducing the bush bolt head thickness as far as possible, can reduce the fatigue of spring and increase its life, and easy to install.

As shown in fig. 1 and fig. 2, in the present embodiment, a connection arm 102 is disposed between the grip 10 and the insertion groove 101, the connection arm 102 is a hollow structure 1021, and the entire grip 10 can be made of aluminum alloy, so that the weight of the grip 10 is ensured to be light under the condition of satisfying the structural strength. Furthermore, the hollow-out processing is performed on the connecting support arm 102, so that the weight of the handle 10 can be effectively reduced, and the portable carrying effect can be achieved.

As shown in fig. 1 and fig. 2, the connecting arm 102 at the hollow 1021 in the present embodiment is provided with an aiming device 103. Can set up towards the direction of bowstring 30 to the fretwork hole, and then convenient to use person aims the archery through sight 103, improves or has ensured the practicality of dismantling the bow.

As shown in fig. 2, the soft layer 104 is wrapped at the holding end of the grip 10 in this embodiment, and the soft layer 104 may be rubber, silica gel, cloth, or foam, which not only improves the comfort of the grip, but also improves the friction of the grip.

As shown in fig. 3, 4 and 5, the insertion slot 101 of the present embodiment includes a bottom catching block 1012, a notch positioning block 1013 and a calibration latch 1014, the bottom catching block 1012 and the notch positioning block 1013 are located on the side of the insertion slot 101 away from the bowstring 30, and the calibration latch 1014 is located on the side of the insertion slot 101 close to the bowstring 30. A first through hole 1015 is arranged between the bottom clamping block 1012 and the notch positioning block 1013, and a second through hole 1016 is arranged between the calibration clamping block 1014 and the bottom of the insertion groove 101. For convenience of explanation, it is assumed that the bow arm 20 of the assembled removable bow is bent toward the bow string 30: posterior curvature and defines the facebow arm 20 as facing posteriorly; and the side of the arm 20 remote from the bowstring 30 is the front.

Specifically, the bottom engaging block 1012 is divided into an engaging plate and a blocking plate on the bottom surface, the notch positioning plate and the blocking plate are both disposed on the side surface of the front surface of the inserting slot 101, the calibration blocking block 1014 is disposed on the side surface of the rear surface of the inserting slot 101, and the projection of the connecting line of the blocking plate, the notch positioning block 1013 and the calibration blocking block 1014 is triangular. Therefore, the stop plate, the notch positioning block 1013 and the calibration block 1014 form a triangular positioning, and limit the front and back bending of the insertion end of the bow arm 20. Meanwhile, the bow arm 20 can be stably fixed by combining the elastic clamping piece 201 and the clamping groove 1011.

As shown in fig. 5, the first opening 1015 and the second opening 1016 on the insertion groove 101 are designed to effectively avoid the stress damage to the insertion groove 101 caused by the vibration of the elastic force of the arm 20, so as to perform the spacing support in the manner of the fulcrum, and the position of the supporting point can be better designed, and meanwhile, the weight and the size of the handle 10 can not be affected, so that the structure has good structural characteristics and the practicability of the structure is improved in the environment of the detachable bow.

In this embodiment, an alignment groove 1017 is provided on an inner side surface of the calibration block 1014, an alignment protrusion 202 is provided on a side surface of the connection end of the arm 20, in order to position the insertion of the arm 20, an alignment groove 1017 is provided on the calibration block 1014 toward the insertion groove 101, and the alignment protrusion 202 on the arm 20 is matched with the alignment groove 1017 to be quickly inserted into the insertion groove 101. And through the cooperation of the alignment groove 1017 and the alignment protrusion 202, the bow arm 20 can be prevented from sliding in the insertion groove 101, and a better stabilizing effect can be achieved. Meanwhile, the alignment groove 1017 and the alignment protrusion 202 can also play a role of fool-proofing, so that the reverse side is prevented from being inserted with the bow arm 20, and the rapid assembly by a user is facilitated.

In this embodiment, the bottom surface of the insertion groove 101 is provided with a positioning protrusion 1018, and the end surface of the connection end of the bow arm 20 is provided with a positioning groove 203. The positioning groove 203 is matched with the positioning protrusion 1018 for limiting, so that the effect of limiting the bow arm 20 is achieved. Meanwhile, the structure of the alignment groove 1017 and the alignment protrusion 202 is matched, so that the stability of the bow arm 20 in use can be improved, and the structural performance of the detachable bow is guaranteed.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
