Description

Technical Field

[0001] The utility model relates to the field of brackets, in particular to a Picatinny rail bracket with adjustable width. Background Art

[0002] The Picatinny rail, also known as the MIL-STD-1913 rail, or the NATO accessory rail of STANAG 4694, is a bracket rail mainly applied to firearms. It includes a rail body arranged along the length direction of the firearm, and a plurality of horizontally arranged transverse grooves provided at the bottom of the rail body. The gun clamp bracket is a fitting for firearms and used to be installed on a support frame. Due to the general-purpose design, the gun clamp bracket generally needs to be compatible with a quick-release plate and a Picatinny rail, so as to be used for installing different models of firearms or accessories, such as a telescopic sight and a firearm without a Picatinny rail. This leads to the need to set multiple groups of clamping positions in the height direction on a gun clamp bracket to respectively match the Picatinny rail and the quick-release plate. Reference can be made to the US patent with the patent number US10612718B2, which sets two sets of dovetail grooves with different widths in the height direction to clamp the Picatinny rail and the quick-release plate. This results in a larger thickness of the bracket and more material consumption. Summary of the Utility Model

[0028] Referring to Figures 1 to 7 , a Picatinny rail bracket with adjustable width, comprising:

[0029] A fixed bracket 10, on one side of the top of the fixed bracket 10, a fixed arm 11 is provided. On the side of the fixed bracket 10, a movable bracket 20 is provided. On the movable bracket 20, a movable arm 21 facing the fixed arm 11 is provided. The movable bracket 20 can move left and right relative to the fixed bracket 10 so that the movable arm 21 approaches or moves away from the fixed arm 11. On the top surface of the fixed bracket 10, at least one lifting groove 12 located between the fixed arm 11 and the movable arm 21 is provided.

[0030] A lifting arm 30, the lifting arm 30 is inserted into the lifting groove 12 and can be lifted in the lifting groove 12; in the raised state, the lifting arm 30 rises to the top of the fixed bracket 10 and faces the movable arm 21. In the retracted state, the lifting arm 30 sinks into the lifting groove 12.

[0031] By providing at least one lifting groove 12 at the top of the fixed bracket 10 and installing a lifting arm 30 in the lifting groove 12, when all the lifting arms 30 are in the retracted state, a clamping groove with the largest clamping width is formed by the fixed arm 11 and the movable arm 21 to clamp the quick-release plate with the largest size. When it is necessary to clamp the Picatinny rail, the corresponding lifting arm 30 is controlled to rise to the raised state, so that the lifting arm 30 and the movable arm 21 cooperate to form a clamping groove with a width adapted to clamp the Picatinny rail. By this method, the lifting arms 30 are all lowered into the lifting grooves 12 when not in use, and only the corresponding lifting arms 30 are raised when needed, so that all the clamping grooves formed by the lifting arms 30, the fixed arm 11 and the movable arm 21 are on the same horizontal plane. Furthermore, there is no need to set the grooves in a stepped manner in the height direction, making the overall thickness of the bracket lower. And because the thickness of the bracket is reduced, the amount of material used can also be reduced, and the cost is lower.

[0032] According to the width of the Picatinny rail and the degree of step of the width of the quick-release plate, the number of lifting grooves 12 provided can be correspondingly selected. Considering the current mainstream sizes, it is preferred to provide only one lifting groove 12, so that a wide clamping groove is formed by the movable arm 21 and the fixed arm 11 to clamp the quick-release plate, and a narrow clamping groove is formed by the movable arm 21 and the lifting arm 30 to clamp the Picatinny rail. The shape of the clamping groove can be various existing types, such as an inverted "T" shape, etc. Preferably, an inclined first wall surface is provided on the surface of the movable arm 21 facing the fixed arm 11, an inclined second wall surface is provided on the surface of the fixed arm 11 facing the movable arm 21, and an inclined third wall surface is provided on the surface of the lifting arm 30 facing the movable arm 21; when the lifting arm 30 is in the retracted state, the movable arm 21 and the fixed arm 11 form a wide dovetail groove through the combination of the first wall surface and the second wall surface, and when the lifting arm 30 is in the raised state, the movable arm 21 and the lifting arm 30 form a narrow dovetail groove through the combination of the first wall surface and the third wall surface.

[0033] In this solution, the lifting of the lifting arm 30 can be operated by the user himself, but in order to simplify the operation method, it is preferred that a first elastic reset member 40 connected to the lifting arm 30 and used to drive the lifting arm 30 to rise is provided in the lifting groove 12, so that the first elastic reset member 40 automatically bounces the lifting arm 30 upward to the raised state. When installing the Picatinny rail, except for the lifting arm 30 or the fixed arm 11 that cooperate with the movable arm 21 to clamp the Picatinny rail, the remaining lifting arms 30 located below the Picatinny rail will be pressed down into the lifting groove 12 to be in the retracted state by the lower end surface of the Picatinny rail, and the effect of installing the quick-release plate is the same.

[0034] In this solution, it is preferred that a mating groove 123 is provided at the bottom of the lifting groove 12, and the end of the first elastic reset member 40 is inserted into the mating groove 123, facilitating the installation of the first elastic reset member 40. Preferably, the first elastic reset member 40 is a first reset spring. In other embodiments, it can also be an elastic rubber column, two mutually repulsive magnets, etc.

[0035] For further optimization, it is preferred that at least one limiting hole 121 penetrating through to the bottom of the fixed bracket 10 is provided at the bottom of the lifting groove 12. A limiting pin 50 is provided at the bottom of the fixed bracket 10, passing through the limiting hole 121 and connecting to the bottom of the lifting arm 30. The limiting pin 50 includes a head, and the size of the head is larger than that of the limiting hole 121. When the lifting arm 30 is in the raised state, the head abuts against the bottom surface of the fixed bracket 10, thereby limiting the maximum height of the lifting arm 30 rising to the top surface of the fixed bracket 10 through the limiting pin 50. At the same time, this structure can also be used to jointly fix the first elastic reset member 40 by the lifting arm 30 and the lifting groove 12.

[0036] In other embodiments, it can also be selected to glue the two ends of the first reset spring to the bottom surface of the lifting groove 12 and the bottom surface of the lifting arm 30 respectively, which can also play a role in limiting the lifting arm 30.

[0037] For further optimization, it is preferred that a free groove 31 is provided along the height direction on the back surface of the lifting arm 30. A fixing groove 32 is provided on one side at the top of the free groove 31. A locking hole 13 extending to the side wall of the lifting groove 12 is provided on the outer side surface of the fixed bracket 10 facing away from the movable bracket 20. A locking rod 60 that can move horizontally in the locking hole 13 and whose end is inserted into the free groove 31 is provided in the locking hole 13. A driving handle 61 connected to the locking rod 60 is provided on the outer side of the fixed bracket 10. When the lifting arm 30 is in the retracted state, the fixing groove 32 is aligned with the locking hole 13 and the end of the locking rod 60 can move horizontally into the fixing groove 32. Through this structure, under normal conditions, the lifting arm 30 automatically bounces upward to the raised state under the action of the first reset spring. When the lifting arm 30 is pressed down to the retracted state, the locking rod 60 is moved through the driving handle 61, so that the locking rod 60 horizontally enters the fixing groove 32, and the lifting arm 30 can be fixed in the retracted state.

[0038] For further optimization, it is preferred that a communication hole 14 extending to the inner wall of the locking hole 13 is provided on the outer wall of the fixed bracket 10 facing away from the fixing groove 32. A second elastic reset member 70 abutting against the locking rod 60 is provided in the communication hole 14. An end cover 71 abutting against the outer end of the second elastic reset member 70 is provided at the outer end of the communication hole 14. The second elastic reset member 70 gives the locking rod 60 an elastic force moving in the direction towards the fixing groove 32, so that when the lifting arm 30 descends into the lifting groove 12 and is in the retracted state, the locking rod 60 is automatically bounced into the fixing groove 32 through the second reset device.

[0039] For further optimization, preferably, a moving groove 62 is provided at the bottom of the front end of the locking rod 60, the direction of the moving groove 62 is perpendicular to the direction of the locking hole 13, an auxiliary hole penetrating to the bottom of the locking hole 13 is provided at the bottom of the fixed bracket 10, and a limiting block 80 extending into the locking hole 13 and inserted into the moving groove 62 is inserted in the auxiliary hole. The locking rod 60 is restricted by the cooperation of the limiting block 80 and the auxiliary hole, so that the locking rod 60 can move while preventing it from detaching. In other ways, the locking rod 60 can also be prevented from detaching by providing an anti-detaching sleeve sleeved on the outer side of the driving handle 61 on the outer side of the fixed bracket 10.

[0040] In other embodiments without using the first elastic reset member 40 to control the lifting arm 30, a groove body can also be provided on one side of the lower part of the free groove 31, so that when the lifting arm 30 is in the raised state, the lifting arm 30 is also locked in the raised state by the locking rod 60 entering the groove body. In other ways, the position of the lifting arm 30 can also be controlled by controlling the frictional force between the lifting arm 30 and the inner wall of the lifting groove 12.

[0041] In other embodiments, the position of the lifting arm 30 can also be locked by providing a pressing bolt abutted against the surface of the lifting arm 30 on the fixed bracket 10.

[0042] In this solution, preferably, a guide rod 33 is provided at the bottom of the lifting arm 30, and a jack 122 penetrating to the bottom of the fixed bracket 10 is provided at the bottom of the lifting groove 12, and the guide rod 33 is inserted into the jack 122.

[0043] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
