Technical Field

[0001] The utility model relates to a shooting detachable bracket with a long barrel, in particular to a locking mechanism of the bracket. Background Art

[0002] A firearm with a long barrel has relatively higher requirements for the stable support of a shooting bracket. Therefore, a bracket with only one support point may be difficult to meet such requirements. A bracket with support points at two positions, front and back, usually has a non-adjustable front-to-back spacing and cannot be adapted to long-barrel firearms of different models.

[0003] The Chinese utility model patent with the publication number CN213021214U discloses a foldable individual training shooting bracket, which includes a base and two support seats foldably arranged at both ends of the base. Its support stability is good, but the spacing between the two support seats is fixed and non-adjustable; the Chinese utility model patent with the publication number CN212227860U discloses a long-barrel bracket with an adjustment function, which realizes the position adjustment of the buttstock bracket (single support seat) through a fixing piece fixedly installed at the top of the telescopic outer rod and a folding support plate slidably installed with the fixing piece, but the structure is still relatively complex. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a bracket with a convenient adjustment of the spacing between the support seats and a simple locking mechanism.

[0005] The technical solution adopted by the utility model to solve the above technical problems is as follows:

[0006] A locking mechanism for connecting a connecting component and a support component of a detachable bracket. The support component includes a main body, and the connecting component includes a first telescopic rod. It is characterized in that it includes a driving part and a movable part connected to each other. The movable part is detachably connected to the first telescopic rod and the main body. When in the locked state, the movable part prevents the first telescopic rod and the main body from axially disengaging from the movable part along the first telescopic rod, and the driving part prevents the movable part from disengaging from the first telescopic rod or the main body; when in the unlocked state, the movable part disengages from the first telescopic rod and / or the main body.

[0007] Furthermore, it also includes a driving rod and an end cap. The driving part is fixedly connected to the movable part through the driving rod, and the driving rod rotates in the rotation channel of the end cap.

[0009] Further, the first connection end of the first telescopic rod has a first through hole, and the movable part has a protrusion. In the locked state, the protrusion protrudes from the first through hole.

[0010] Further, the main body has a tube, and the tube has a positioning part corresponding to the first through hole. In the locked state, the protrusion cooperates with the positioning part, and the positioning part prevents the movable part from detaching from the main body.

[0011] Further, the main body has a tube, the tube is fixedly connected to the end cover, and the rotation channel of the end cover extends along the axial direction of the tube.

[0012] Further, the first connection end of the first telescopic rod has a first through hole, the main body has a tube, and the tube has a second positioning through hole. In the locked state, the protrusion of the movable part protrudes from the first through hole and the second positioning through hole.

[0013] Further, the movable part switches between the locked state and the unlocked state in a linear movement manner.

[0014] Further, the movable part is a pin, and the first connection end and the tube are pin-connected through the movable part.

[0015] Further, the cross section of the first telescopic rod is non-circular.

[0030] The present utility model will be further described in detail below in conjunction with the embodiments in the drawings.

[0031] Refer to Figures 1-6 . The detachable bracket of the present utility model includes a support assembly 100 and a connection component 200, and the support assembly 100 and the connection component 200 are detachably connected. As Figure 1 , Figure 2 shown, in one embodiment, 2 support assemblies 100 are respectively detachably connected to both ends of the connection component 200. In one embodiment, the connection component 200 includes a first telescopic rod 210 and a second telescopic rod 220 that are telescopically connected, and the first telescopic rod 210 and the second telescopic rod 220 control the telescopic state between the two through a telescopic control member 300. The telescopic control member 300 can be common control members such as a knob, a button, a buckle, etc., which will not be elaborated here. The first connection end of the first telescopic rod 210 is detachably connected to one support assembly 100, and the second connection end of the second telescopic rod 220 is detachably connected to the other support assembly 100.

[0032] In one embodiment, the first telescopic rod 210 and the second telescopic rod 220 are coaxially slidably connected, and the second telescopic rod 220 is sleeved inside the first telescopic rod 210; in other embodiments, the first telescopic rod 210 and the second telescopic rod 220 can also be slidably connected in other ways, such as non-coaxial sliding connection, and other implementation manners will not be elaborated here.

[0033] The support component 100 includes a main body 110 and an opening 111 located at the upper part of the main body 110, which is used to support the middle and lower parts of the barrel. The openings 111 of two support components 100 can support the barrel more stably with one in front and the other behind. The main body 110 is axially symmetric along the vertical center line. As Figures 4-6 shown, the opening 111 of the main body 110 is also axially symmetric along the vertical center line. The width of the upper part of the opening 111 is greater than or equal to the width of the bottom of the opening 111, and the minimum width of the opening 111 is greater than the width of the barrel. The opening 111 can be U-shaped or V-shaped, or other shapes that meet the opening conditions of the present utility model. As Figure 4 shown, in one embodiment, a buffer pad 130 is provided at the edge of the opening 111, which not only enhances the friction between the barrel and the edge of the opening 111 to improve the stability of the barrel support, but also reduces the impact and wear of the barrel on the edge of the opening 111 when placed. In one embodiment, the buffer pad 130 is made of rubber.

[0034] The support component 100 further includes a balance adjustment part 120 located at the lower part of the main body 110. In one embodiment, the balance adjustment part 120 is symmetrically arranged on both sides of the lower part of the main body 110 and can adjust the height of the corresponding position of the main body 110 within a certain range. In one embodiment, the balance adjustment part 120 has an internal thread 121 and a nut 122. The axis of the internal thread 121 extends along the vertical direction and is parallel to the center line of the main body 110; the nut 122 has an external thread that matches the internal thread 121. When the nut 122 is rotated, the height of the corresponding side of the main body 110 can be adjusted. In other embodiments, the balance adjustment part 120 can also be other structures that can manually or automatically adjust the height of the main body 110.

[0035] The connection component 200 is connected to the support component 100 through a locking mechanism 500. The locking mechanism 500 has a locked state and an unlocked state. When in the locked state, the connection component 200 and the support component 100 are kept in a stable connection state. When in the unlocked state, the connection component 200 and the support component 100 are in a detachable state.

[0036] The locking mechanism 500 includes a driving part 510 and a movable part 520 connected to the driving part 510. In one embodiment, taking the first connection end of the first telescopic rod 210 as an example, the first connection end allows the movable part 520 to freely enter and exit the inside of the first telescopic rod 210 in the unlocked state, and the first connection end has a first through hole 211. The first through hole 211 allows the protrusion 521 of the movable part 520 to extend out of the inside of the first telescopic rod 210 through the first through hole 211 in the locked state. The protrusion 521 prevents the first connection end of the first telescopic rod 210 from axially detaching from the movable part 520, that is, the first telescopic rod 210 is locked by the protrusion 521.

[0037] As shown in Figure 3 and Figure 4 , a main body connection position is provided at the lower part of the main body 110, and the connection component 200 and the support component 100 are connected at the main body connection position. In one embodiment, the main body connection position is a pipe 140 penetrating through the main body 110, and a positioning portion is provided inside the pipe 140. In one embodiment, the positioning portion is a recess 141. In the embodiment where the positioning portion is the recess 141, the movable portion 520 has a protrusion 521. After the protrusion 521 enters the recess 141, the main body 110 is prevented from axially disengaging from the movable portion 520, that is, the main body 110 is locked by the protrusion 521. Those skilled in the art can also set corresponding guiding structures or sliding structures on the basis of the recess 141 and the protrusion 521 to enhance the locking effect and unlocking convenience of the two. For example, grooves are provided on the surface of the recess 141, and protrusions cooperating with the grooves are provided on the surface of the protrusion 521, etc. In one embodiment, the movable portion 520 rotates to make the protrusion 521 enter or leave the recess 141. At this time, the driving portion 510 can be a knob, and the driving portion 510 prevents the movable portion 520 from axially disengaging from the main body connection position or the first connection end, as shown in Figure 5 ; in another embodiment, the movable portion 520 makes the protrusion 521 enter or leave the recess 141 through linear displacement. At this time, the driving portion 510 can be a button with a reset function, and the driving portion 510 prevents the movable portion 520 from radially disengaging from the main body connection position or the first connection end.

[0038] In one embodiment, the first connection end of the first telescopic rod 210 is sleeved inside the pipe 140, and the locking mechanism 500 is rotatably connected to the first connection end of the first telescopic rod 210 through an end cover 400. Specifically, the end cover 400 is connected to the first connection end of the first telescopic rod 210. In one embodiment, the first connection end has a second through hole 212, and the connection feet 410 of the end cover 400 enter the inside of the second through hole 212 and hook the edge of the second through hole 212. In one embodiment, the connection feet 410 are two symmetrically arranged, and are respectively hooked to the edges of the symmetrically arranged first through hole 211 and second through hole 212, so that the end cover 400 is fixedly connected to the first connection end 212. The end cover 400 has a rotation channel 420 extending along the axial direction of the first telescopic rod 210, and the locking mechanism 500 rotates in the rotation channel 420. For example, the driving portion 510 is fixedly connected to the movable portion 520 through a driving rod 530. When the driving portion 510 is rotated, the driving rod 530 rotates in the rotation channel 420 and drives the movable portion 520 to rotate simultaneously. That is, the movable portion 520 switches between the locked state and the unlocked state in a rotational manner. In another embodiment, the end cover 400 is fixedly connected to the pipe 140.

[0039] In another embodiment, the first connecting end of the first telescopic rod 210 can also be sleeved outside the tube 140. At this time, the positioning portion of the tube 140 is a second positioning through hole (not shown in the figure). When the protrusion 521 of the movable portion 520 extends out from the second positioning through hole and the first through hole 211, it simultaneously prevents the tube 140 and the first connecting end of the first telescopic rod 210 from axially disengaging from the movable portion 520; when the protrusion 521 of the movable portion 520 leaves the second positioning through hole and / or the first through hole 211, the tube 140 and the first connecting end of the first telescopic rod 210 are released from the state of being constrained by the protrusion 521.

[0040] In some embodiments, the first connecting end of the first telescopic rod 210 and the main body connection position are connected by a locking mechanism 500 in other ways. For example, the locking mechanism 500 includes a plugging groove located at the main body connection position, and the outer edge of the first connecting end is matched with the plugging groove. When the outer edge of the first connecting end is inserted into the plugging groove, the first telescopic rod 210 is connected to the main body 110, but such a connection may not be stable. Further, when the first connecting end approaches or contacts the solid part of the main body connection position, the movable portion 520 of the locking mechanism 500 is a pin, and both the first connecting end and the solid part of the main body connection position have connection holes (not shown in the figure) allowing the pin to pass through, while the driving portion 510 of the locking mechanism 500 is not allowed to pass through the connection holes. At this time, the first connecting end and the solid part of the main body connection position are pin-connected. That is, the movable portion 520 switches between the locked state and the unlocked state in a linear movement manner.

[0041] In one embodiment, the cross-section of the first telescopic rod 210 is non-circular. As Figure 4 , Figure 5 shown, the cross-section of the first telescopic rod 210 is oblong; in other embodiments, the cross-section of the first telescopic rod 210 is oval, square or other non-circular shapes. The non-circular cross-section makes it difficult for the first telescopic rod 210 and the second telescopic rod 220 to roll or rotate relative to each other, enhancing the internal connection and the external connection stability of the connection assembly 200.

[0042] In one embodiment, the main body 110 has a reinforcing rib 150 to enhance the strength of the main body 110. In one embodiment, the reinforcing rib 150 is symmetrically arranged along the vertical midline of the main body 110.
