Description

Technical Field

[0001] The present invention relates to the field of mechanical technology, and in particular to a continuous clamping mechanism for a Picatinny rail type pendant. Background Art

[0002] With the development of military weapons and equipment in various countries, a large number of weapons and equipment have been updated. In order to achieve beyond visual range, day and night observation and aiming, a large number of day and night general observation and aiming equipment are equipped on individual weapons. For sniper rifles, anti-tank rocket launchers, shoulder-fired defense missiles and other related equipment used at long distances or at night, they need to be equipped with relevant sights to effectively hit the target. The internationally used interfaces of these individual weapons and equipment are Picatinny rails, so the matching pendants are widely used. Their reliability and ease of operation play a vital role in the relevant sights.

[0003] Generally, the mounting mechanism of traditional Picatinny rail pendants mostly adopts the form of nuts and screws, and its locking form is laborious and time-consuming to operate. During the use of firearms, due to the changes in continuous impact, the nut may rotate relatively, which may cause the locking form to fail, causing the pendant clamp to loosen or the device to be used abnormally. There are also quick-loading Picatinny rail pendants, but due to the influence of various gun types, processing accuracy and different standards of various countries, the quick-loading structure needs to readjust the tightening width position during the change of gun types, so that it may be necessary to readjust the Picatinny rail pendant during the process of replacing other firearms, which increases the replacement time. Under complex battlefield situations, it is very likely to bring adverse effects. Chinese invention patent CN202110231083.5 applied for by Ningbo Ai Ke Outdoor Products Technology Co., Ltd.: A quick clamping mechanism for a leather rail interface discloses a short lever arm of the locking handle, increased resistance during locking, large torque during loading and unloading, and inconvenient operation. At the same time, since it also adopts a quick-loading method, it also has the shortcomings of a quick-loading mechanism, such as large processing errors or inconsistent standards of the Picatinny on weapons and equipment, which will cause the defect of loose locking. Summary of the invention

[0004] In view of the above problems, the purpose of the present invention is to propose a continuous clamping mechanism for a Picatinny rail type pendant, which adopts a worm gear meshing mode through the locking position. The worm is driven by the handle to continuously rotate back and forth to drive the spur gear, thereby driving the worm, and the worm is meshed with the turbine. The turbine has a thread that rotates relative to the locking link, and the distance between the locking block and the connecting seat of the Picatinny rail changes relatively, thereby realizing the loading and unloading of the Picatinny rail pendant.

[0005] At the same time, it has the characteristics of continuous adjustment, easy operation, high locking reliability and good anti-loosening effect, which is convenient for quickly replacing the sight with other weapons and equipment on the battlefield; at the same time, this design is light in weight and suitable for individual equipment design and use, reducing the carrying weight, and this design also has the characteristics of relatively small size.

[0006] To achieve the above object, the present invention adopts the following specific technical solutions:

[0007] The present invention provides a continuous clamping mechanism for a Picatinny rail type hanging part, comprising: a main body and a locking device;

[0008] The main body includes: a connecting seat, a locking block, a locking connecting rod and a return spring;

[0009] The connecting seat is of an integral structure, and the locking connecting rod is of a T-shaped structure, including a connecting rod end and a T-shaped end, and the connecting rod end is provided with a thread;

[0010] The connecting rod end of the locking connecting rod sequentially passes through the locking block and the return spring and then is threadedly connected to the locking device located inside the connecting seat. One end of the return spring abuts against the connecting seat, and the other end abuts against the locking block;

[0011] The T-shaped end of the locking connecting rod is clamped in the groove on one side of the locking block;

[0012] The locking device controls the length of the locking connecting rod to screw in or out by rotation, thereby controlling the relative distance between the locking block and the connecting seat, and further realizing the clamping and detachment of the Picatinny rail type hanging part and the Picatinny rail.

[0013] Preferably, the locking device includes: a turbine and a turbine limit nut;

[0014] A threaded hole is provided at the center of the turbine, and the connecting rod end of the locking connecting rod is in threaded fit with the threaded hole at the center of the turbine through threads;

[0015] The turbine is restricted from moving outwards by the turbine limit nut so as to be in fit with the connecting seat;

[0016] Preferably, the locking device further includes: a driving spur gear, a worm retaining ring and a worm;

[0017] The turbine is meshed and connected with the gear of the worm;

[0018] A worm retaining ring is provided at the shoulder of the worm for restricting the position of the worm; so that it is located inside the connecting seat and is in meshing fit with the turbine;

[0019] The top end of the worm is fixedly connected to the driving spur gear to form an integral structure, and the driving spur gear drives the worm to rotate synchronously.

[0020] Preferably, the locking device further includes: an anti-loosening ball, and the anti-loosening ball abuts in the teeth of the turbine for preventing the turbine from loosening and rotating.

[0021] Preferably, a handle device is further included; the handle device is used to rotate the driving spur gear;

[0022] The handle device includes: a handle, a driving tongue, a driving spring, and a handle connecting sleeve;

[0023] The circular end of the handle connecting sleeve covers above the driving spur gear. The driving tongue passes through the hollow cylindrical end of the handle connecting sleeve. One end of the driving tongue is fixedly connected to the handle by a thread. A driving spring is installed on the driving tongue. Under the action of the driving spring, the other end of the driving tongue abuts against the teeth of the driving spur gear, and as the handle connecting sleeve and the handle rotate together, the driving worm is driven.

[0024] Preferably, the handle device further includes a limiting piece;

[0025] The handle drives the driving tongue to move away from the driving spur gear, separating the driving tongue from the driving spur gear;

[0026] When the driving tongue moves away from the driving spur gear, the limiting piece is used to limit the movement position of the driving tongue; to prevent the handle and the driving tongue from moving too far and detaching from the handle connecting sleeve.

[0027] Preferably, when the continuous clamping mechanism of the Picatinny rail type hanging part performs continuous locking:

[0028] Taking the worm as the rotation center, push the handle to rotate clockwise to the front of the connecting seat, pull the handle outward along the rotation center to separate the driving tongue from the driving spur gear, rotate the handle counterclockwise, and after turning back to the rear of the connecting seat, push the driving tongue inward so that it abuts against the teeth of the driving spur gear. Perform such reciprocating motion. The driving spur gear and the worm rotate together. When performing continuous locking, the worm always performs a forward one-way rotation motion to drive the turbine to perform a forward one-way rotation. When the turbine rotates, due to the threaded fit between the turbine and the locking connecting rod, the locking connecting rod performs a screwing-in motion, reducing the relative distance between the connecting seat and the locking block, and clamping the Picatinny rail type hanging part on the Picatinny rail.

[0029] Preferably, when the continuous clamping mechanism of the Picatinny rail type hanging part is disassembled:

[0030] Pull the handle outward to separate the driving tongue from the driving spur gear, rotate clockwise to the front of the connecting seat, push the driving tongue inward so that it abuts against the teeth of the driving spur gear, rotate the handle counterclockwise, and after turning back to the rear of the connecting seat, perform reciprocating motion. Since the driving spur gear and the worm rotate together, when the driving spur gear performs continuous rotation, the worm always performs a reverse one-way rotation motion to drive the turbine to perform a reverse one-way rotation. The turbine and the locking connecting rod are in threaded fit, so that the locking connecting rod performs a screwing-out motion, increasing the relative distance between the connecting seat and the locking block, realizing the detachment of the Picatinny rail type hanging part from the Picatinny rail, and finally realizing disassembly.

[0031] Preferably, the handle limit sleeve is fixed by screws and installed above the connecting seat. It cooperates with the hollow cylindrical end of the handle connecting sleeve to limit the overall rotation angle of the handle, the driving tongue, and the handle connecting sleeve.

[0032] Compared with the existing technology, the present invention has the following advantages:

[0033] 1. The present invention optimizes the locking mechanism, can continuously adjust the clamping force of the Picatinny rail type pendant, is not affected by the machining errors or different standards of the Picatinny rail, has stronger adaptability, and due to its multi-stage transmission, makes its operation more labor-saving.

[0034] 2. In the present invention, by the anti-loosening ball bead pressing against the turbine teeth, the turbine can be effectively prevented from loosening and rotating, so as to achieve the anti-loosening purpose; the anti-loosening effect and reliability are improved.

[0035] 3. In the present invention, by designing the thrust of the driving spring on the driving tongue outward, the driving tongue restricts the rotation of the driving gear, and at the same time further restricts the rotation of the worm and worm wheel, realizing further anti-loosening, so that the present invention can achieve a double anti-loosening effect and has higher reliability.

[0036] 4. The present invention has a pendant mechanism with continuous adjustment, convenient operation, and good anti-loosening effect. At the same time, it has the characteristics of small volume, light weight, and strong adaptability, and can be widely used to externally hang other accessories on various weaponry with Picatinny rails, and has a wide application range.

It should be understood that the specific embodiments described herein are only used to explain the present invention and do not constitute a limitation to the present invention.

[0060] Figure 4 Shows a cross-sectional view of a continuous clamping mechanism of a Picatinny rail pendant according to an embodiment of the present invention.

[0061] As Figures 1-4 shown, the continuous clamping mechanism of the Picatinny rail pendant provided by the embodiment of the present invention includes: a main body, a handle device and a locking device.

[0062] The handle device is installed above the main body, and the locking device is fitted inside the main body. The locking device is controlled by the handle device to lock and open, so as to control the main body to perform continuous clamping.

[0063] Figure 5 Shows a schematic structural diagram of a connecting seat according to an embodiment of the present invention.

[0064] Figure 6 Shows a schematic structural diagram of a locking block according to an embodiment of the present invention.

[0065] Figure 7 Shows a schematic structural diagram of a locking link according to an embodiment of the present invention.

[0066] As Figures 5-7 shown, the main body includes: a connecting seat 1, a locking block 11, a locking link 14 and a return spring 15.

[0067] The connecting seat 1 is of an integral structure, and the locking link 14 is of a T-shaped structure, including a link end and a T-shaped end, and the link end is provided with a thread. The link end of the locking link 14 sequentially passes through the locking block 11 and the return spring 15 and then is threadedly connected to the locking device inside the connecting seat 1. One end of the return spring 15 abuts against the connecting seat 1, and the other end abuts against the locking block 11, for applying an outward elastic force to the connecting seat 1 and the locking block 11 to prevent the connecting seat 1 and the locking block 11 from sliding freely relative to each other, resulting in the problem that the locking block 11 needs to be manually pushed outward before the Picatinny rail can be clamped; the T-shaped end of the locking link 14 is clamped in a groove on one side of the locking block 11 to prevent the locking link 14 from rotating.

[0068] The locking device controls the length of the locking link 14 to screw in or out by rotation, thereby controlling the relative distance between the locking block 11 and the connecting seat 1, and thus realizing the clamping and detachment of the Picatinny rail type pendant and the Picatinny rail.

[0072] Figure 11 The schematic structural diagram of the turbine provided according to an embodiment of the present invention is shown.

[0073] Figure 12 The schematic structural diagram of the turbine limit nut provided according to an embodiment of the present invention is shown.

[0074] As Figures 8-12 As shown, the locking device includes: a driving spur gear 7, a worm gland 10, a worm 12, a turbine 13, a turbine limit nut 16 and an anti-loosening ball 17.

[0075] A threaded hole is provided at the center of the turbine 13, and the connecting rod end of the locking link 14 is threadedly engaged with the threaded hole at the center of the turbine 13.

[0076] The turbine 13 is restricted from moving outwards by the turbine limit nut 16 so that it fits with the connecting seat 1, and the turbine 13 is meshed and connected with the gear of the worm 12. The anti-loosening ball 17 abuts in the teeth of the turbine 13 to effectively prevent the turbine 13 from loosening and rotating, so as to achieve the purpose of anti-loosening.

[0077] A worm gland 10 is provided at the shoulder of the worm 12 to limit the position of the shaft of the worm 12. It is located inside the connecting seat and just meshes with the turbine 13;

[0078] The top end of the worm 12 is fixedly connected to the driving spur gear 7 to form an integral structure, and the worm 12 rotates synchronously with the driving spur gear 7.

[0079] The handle device is used to rotate the driving spur gear 7, drive the worm 12 to rotate, the worm 12 drives the turbine 13 to rotate, and the turbine 13 makes the locking link 14 perform screw-in and screw-out movements after rotation.

[0080] Figure 13 The schematic structural diagram of the handle provided according to an embodiment of the present invention is shown.

[0081] Figure 14 Shows a schematic structural diagram of a driving tongue provided according to an embodiment of the present invention.

[0082] Figure 15 Shows a schematic structural diagram of a handle limit sleeve provided according to an embodiment of the present invention.

[0083] Figure 16 Shows a schematic structural diagram of a handle cover provided according to an embodiment of the present invention.

[0084] Figure 17 Shows a schematic structural diagram of a handle connecting sleeve provided according to an embodiment of the present invention.

[0085] As Figures 13-17 shown, the handle device includes: a handle 2, a driving tongue 3, a driving spring 4, a limiting piece 5, a handle limit sleeve 6, a handle cover 8, and a handle connecting sleeve 9.

[0086] The circular end of the handle connecting sleeve 9 covers above the driving spur gear 7, and the handle cover 8 is installed on the handle connecting sleeve 9 for fixing the handle connecting sleeve 9. The rod portion of the handle cover 8 passes through the central hole of the handle connecting sleeve 9 and is fixed to the worm 12 by threads.

[0087] The driving tongue 3 passes through the hollow cylindrical end of the handle connecting sleeve 9. One end of the driving tongue 3 is fixedly connected to the handle 2 by threads. A driving spring 4 is installed on the driving tongue 3. Under the action of the driving spring 4, the other end of the driving tongue 3 abuts against the teeth of the driving spur gear 7, and as the handle connecting sleeve 9 and the handle 2 rotate together, the worm 12 is driven; the handle limit sleeve 6 is fixed by screws and installed above the connecting seat 1, and cooperates with the hollow cylindrical end of the handle connecting sleeve 9 to limit the overall rotation angle of the handle 2, the driving tongue 3, and the handle connecting sleeve 9.

[0088] Relative movement is possible between the handle 2 and the handle connecting sleeve 9, that is, the handle 2 can drive the driving tongue 3 to move away from the driving spur gear 7, separating the driving tongue 3 from the driving spur gear 7.

[0089] When the driving tongue 3 moves away from the driving spur gear 7, the limiting piece 5 is used to limit the movement position of the driving tongue 3. To prevent the handle 2 and the driving tongue 3 from moving excessively and detaching from the handle connecting sleeve 9.

[0090] During the working process of the continuous clamping mechanism of the Picatinny rail type hanging part provided by the present invention, taking Figure 1 as an example for illustration. As Figure 1 shown, from left to right is the clockwise direction, Figure 1The left side of [the relevant part] is the rear of the connecting seat 1, and the right side is the front of the connecting seat 1; the handle 2 rotates around the worm 12. Pushing towards the center (i.e., towards the direction of the worm 12) is inwards, and pulling in the opposite direction is outwards;

[0091] When the continuous clamping mechanism of the Picatinny rail - type pendant is continuously locked:

[0092] Taking the worm 12 as the rotation center, push the handle 2 to rotate clockwise to the front of the connecting seat 1, pull the handle 2 outwards along the rotation center to separate the driving tongue 3 from the driving spur gear 7, rotate the handle 2 counter - clockwise, after turning back to the rear of the connecting seat 1, push inwards to make the driving tongue 3 press against the teeth of the driving spur gear 7, and perform such reciprocating motion. Since the driving spur gear 7 rotates together with the worm 12, when the driving spur gear 7 is continuously locked, the worm 12 always performs a forward one - way rotational motion to drive the turbine 13 to perform a forward one - way rotation. When the turbine 13 rotates, since the turbine 13 is in threaded cooperation with the locking connecting rod 14, the locking connecting rod 14 performs a screwing - in motion. Therefore, the relative distance between the connecting seat 1 and the locking block 11 therebetween is reduced, and the Picatinny rail - type pendant is clamped on the Picatinny rail. After the locking is completed, return the handle 2 to the rear of the connecting seat 1, so that the handle connecting sleeve 9 enters the handle limiting sleeve 6, restricting the counter - clockwise rotation of the whole of the handle 2, the driving tongue 3 and the handle connecting sleeve 9. At the same time, under the action of the driving spring 4, the driving tongue 3 abuts against the spur gear 7. Since it is in the locked state, it can effectively restrict the clockwise rotation of the handle 2 etc., making the locking more reliable.

[0093] When the continuous clamping mechanism of the Picatinny rail - type pendant is disassembled:

[0094] Pull the handle 2 outwards to separate the driving tongue 3 from the driving spur gear 7, rotate clockwise to the front of the connecting seat 1, push inwards to make the driving tongue 3 press against the teeth of the driving spur gear 7, rotate the handle 2 counter - clockwise, after turning back to the rear of the connecting seat 1, perform reciprocating motion. Since the driving spur gear 7 rotates together with the worm 12, when the driving spur gear 7 rotates continuously, the worm 12 always performs a reverse one - way rotational motion to drive the turbine 13 to perform a reverse one - way rotation. When the turbine 13 rotates, since the turbine 13 is in threaded cooperation with the locking connecting rod 14, the locking connecting rod 14 performs a screwing - out motion. Therefore, the relative distance between the connecting seat 1 and the locking block 11 therebetween is increased, realizing the detachment of the Picatinny rail - type pendant from the Picatinny rail, and finally realizing disassembly.

[0095] In the present invention, the connecting seat 1 and the locking block 11 are in clearance fit, and the fitting accuracy ensures that their relative angular error is small, and it will not cause a large zero - position deviation due to being installed at different positions on the Picatinny rail, thus ensuring the shooting accuracy.

[0096] The locking principle of the present invention enables a smaller lever handle to be designed, so it is lighter in weight, achieving a lightweight design.

[0097] The present invention can be continuously locked or clamped, and will not cause insufficient clamping force due to machining errors or different standards of Picatinny rails, affecting the stability of the connection. At the same time, due to the primary transmission of the worm and worm gear plus the secondary transmission of the thread and the long lever arm of the handle, a very small force needs to be applied, so the operation is more labor-saving and the clamping is more reliable; after locking, under the dual action of the anti-loosening ball 17 and the self-locking of the worm and worm gear, it can effectively reduce the rotation of the turbine 13 caused by vibrations and impacts such as firearms, resulting in adverse factors such as loosening of the clamping and decreased reliability, effectively achieving the anti-loosening effect.

[0098] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.

[0099] The above specific implementation manners of the present invention do not constitute a limitation to the protection scope of the present invention. Any other corresponding changes and deformations made according to the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
