The first sealing module is connected to the female connector and is sleeved on the outside of the female connector. The second sealing module is connected to the male connector and is sleeved on the outside of the male connector. The above-mentioned structure is arranged to facilitate the disassembly and installation of the male and female connectors and the mounting bases. However, the existing quick-release structure cannot circumferentially limit the components of the male end, which may cause the connection between the male end and the female end to rotate during use, affecting the use effect and having certain limitations. Summary of the invention

[0004] The present invention provides a spring structure of a quick-release air gun to solve the above problem.

[0005] The spring structure of a quick-release air gun of the present invention adopts the following technical solution: a spring structure of a quick-release air gun comprises a female end, a male end, a locking plate, and an outer tube; the female end is a tube-shaped tube arranged before and after the axis.

[0006] The male end is cylindrical and coaxially arranged with the female end; the rear end of the male end can be inserted into the front end of the female end; a ring groove and a clamping hole are arranged on the side wall of the male end; the clamping hole is arranged on the front side of the ring groove, and multiple clamping holes are evenly distributed along the circumference of the male end.

[0007] The locking disk is installed on the side wall of the female end so as to rotate radially around the female end; there are two limit grooves distributed front and back on the locking disk; the limit groove is a through groove along the radial direction of the female end, and the groove diameter of the limit groove is smaller than the diameter of the limit groove; rollers are provided in the limit groove so as to slide along the radial direction of the female end; initially, the lower end of the roller extends out of the limit groove.

[0008] The outer cylinder is slidably mounted on the female end forward and backward; a locking spring is connected between the outer cylinder and the female end; an escape space is provided on the inner wall of the front end of the outer cylinder; the outer cylinder is moved backward to compress the locking spring so that the escape space corresponds to the locking disk. When the male end is inserted into the female end, the male end pushes the roller to the escape space. When the annular groove and the clamping hole of the male end correspond to the roller, the roller in the limiting groove at the front end of the locking disk falls into the annular groove, and the roller in the limiting groove at the rear end of the locking disk falls into the clamping hole. The outer cylinder is released, and the locking spring releases force to drive the outer cylinder to move forward and reset. The inner wall of the outer cylinder abuts against the roller, and the roller is limited to the annular groove and the clamping hole, thereby realizing the axial limitation of the male end and the female end; the clamping limit of the clamping hole and the roller in the limiting groove located on the front side realizes the rotation limitation of the male end.

[0009] Furthermore, an auxiliary mechanism is provided between the outer cylinder and the female end; after the male end is inserted into the female end, the auxiliary mechanism limits the forward and backward movement of the outer cylinder, and cooperates with the clamping hole and the roller in the limiting groove located on the front side to realize the limiting of the rotation of the male end; after the male end is pulled out of the female end, the auxiliary mechanism drives the locking disk to rotate 180° radially around the female end, so that the positions of the rollers in the two limiting grooves on the locking disk are interchanged after each disassembly and assembly, so that the contact parts of the two rollers on the locking disk and the male end are alternately interchanged, thereby reducing roller wear and extending the service life of the rollers.

[0010] Furthermore, the auxiliary mechanism includes a T-slot, a rotating shaft, and a matching assembly. The T-slot is arranged on the inner wall of the front end of the outer cylinder and extends along the axis direction of the outer cylinder; the T-slot includes a wide slot section and a narrow slot section; the wide slot section is far away from the axis of the outer cylinder, and the narrow slot section is close to the axis of the outer cylinder; the width of the wide slot section in the tangential direction of the outer cylinder is greater than the width of the narrow slot section in the tangential direction of the outer cylinder; the wide slot section and the narrow slot section form a T shape; the rotating shaft is coaxially fixed on the end face of the locking disk away from the axis of the female end; the rotating shaft is slidably fitted in the narrow slot section of the T-slot; a ratchet is fixed at one end of the rotating shaft away from the axis of the female end; the ratchet is arranged in the wide slot section of the T-slot.

[0011] The mating component is arranged in the narrow groove section of the T-slot; after the male end is inserted into the female end and the outer cylinder is moved forward and reset under the drive of the locking spring, the rotation of the male end around the male end axis is limited due to the locking and limiting of the clamping hole and the roller in the limiting groove on the front side, so as to limit the rotation of the locking disk. At this time, the mating component makes the outer cylinder and the ratchet wheel lock and match to limit the backward movement of the outer cylinder, so that the inner wall of the outer cylinder remains in contact with the roller, and the roller is limited in the annular groove and the clamping hole, so as to realize the rotation of the male end. Double limit locking prevents the outer cylinder from moving backward due to accidental touch, causing the connection between the male end and the female end to become loose. After the male end is pulled out and the outer cylinder is driven forward and reset by the locking spring, when the outer cylinder is pushed backward again by hand, the matching component makes the ratchet and the groove wall of the wide groove section of the T-slot engage, so as to drive the ratchet to drive the locking disk to rotate 180°, and then the matching component disengages the ratchet and the groove wall of the wide groove section of the T-slot. After releasing the hand, the outer cylinder moves forward and resets under the drive of the locking spring.

[0012] Furthermore, the mating component includes a ratchet and a pneumatic structure; a plurality of ratchets are evenly distributed along the axial direction of the outer cylinder; a plurality of receiving grooves are provided on the groove wall of the wide groove section of the T-shaped groove; the ratchet is in a V-shape with the small end facing forward; the small end of the ratchet is rotatably installed on the groove wall of the wide groove section of the T-shaped groove and corresponds to the receiving groove; a torsion spring is connected between the ratchet and the groove wall of the wide groove section of the T-shaped groove; the torsion spring causes the ratchet to be received in the receiving groove.

[0013] The pneumatic structure is used to drive the ratchet to rotate around the small end of the ratchet to move away from the receiving groove when the male end is pulled out and the outer cylinder is driven by the locking spring to move forward and reset, and the outer cylinder is pushed back again by hand, so that the large end of the ratchet extends out of the receiving groove, and the ratchet wheel and the groove wall of the wide groove section of the T-shaped groove are meshed through the ratchet.

[0014] Furthermore, the pneumatic structure includes a sub-air duct, a main air duct, and a pressure control unit; the sub-air duct is arranged on the groove wall of the storage groove away from the ratchet; the sub-air duct is arranged along the tangent direction of the outer cylinder and is perpendicular to the front-to-back direction; the sub-air duct is at the large end of the ratchet; a push column is slidably arranged in the sub-air duct; the push column and the side wall of the ratchet away from the ratchet are abutted; the push column and the side wall of the ratchet away from the ratchet are adsorbed by magnetic force; the main air duct is arranged on the side of the sub-air duct away from the ratchet; the main air duct is arranged front and back, the front end is blocked, and a pressure control structure is arranged at the rear end; the sub-air duct and the main air duct are connected.

[0015] After the male end is pulled out and the outer cylinder is driven forward and reset by the locking spring, when the outer cylinder is pushed back again by hand, the pressure control unit increases the air pressure in the main air channel and the sub-air channel, driving the push column to approach the ratchet wheel, so as to drive the ratchet teeth to rotate around the small end of the ratchet teeth to move away from the receiving groove, so that the large end of the ratchet teeth extends out of the receiving groove, and the ratchet wheel and the groove wall of the wide groove section of the T-shaped groove are meshed through the ratchet teeth.

[0016] Furthermore, the pressure control unit includes an inner ring and an outer ring; the inner ring is coaxially arranged between the outer tube and the female end; and is located at the rear end of the main airway; a piston column is fixed on the end face of the inner ring close to the main airway; the piston column and the main airway are sealed and slidable.

[0017] The outer ring is coaxially sleeved on the outer side of the outer tube; a connecting groove is provided on the side wall of the outer tube; the connecting groove is a through groove; a connecting column is fixedly connected between the outer ring and the inner ring; the connecting column is provided in the connecting groove, and the connecting column and the groove wall of the connecting groove are frictionally matched. After the male end is pulled out and the outer tube is driven forward and reset by the locking spring, when the outer tube is pushed back again by hand, the outer ring is pushed by hand to overcome the friction between the connecting column and the connecting groove, so that the outer ring drives the inner ring forward, drives the piston column to squeeze the gas in the main airway, increases the air pressure in the main airway and the sub-airway, drives the push column to approach the ratchet wheel, drives the ratchet to rotate around the small end of the ratchet tooth to move away from the receiving groove, makes the large end of the ratchet tooth extend out of the receiving groove, and makes the ratchet wheel and the groove wall of the wide groove section of the T-shaped groove mesh through the ratchet tooth.

[0018] Furthermore, the cross section of the annular groove is V-shaped with the small end facing the axis of the male end; and the clamping hole is a rectangular hole.

[0019] Furthermore, a convex ring is fixed on the front end of the male end; a rubber buffer protrusion is provided on the rear end surface of the convex ring; a buffer ring is fixed on the front end surface of the outer tube; a buffer groove is provided on the front end surface of the buffer ring; the buffer groove corresponds to the buffer protrusion and is used to buffer the elastic force of the locking spring.

[0020] Furthermore, an anti-slip protrusion is provided on the outer side wall of the outer cylinder.

[0021] Furthermore, the end face of the locking disk close to the axis of the female end is an arc surface, and has the same diameter as the inner wall of the female end; the end face of the locking disk away from the axis of the female end is an arc surface, and has the same diameter as the outer wall of the female end.

[0022] The beneficial effects of the present invention are:

[0023] 1. Move the outer tube backward to compress the locking spring so that the avoidance space corresponds to the locking disk. When the male end is inserted into the female end, the male end pushes the roller to the avoidance space. When the annular groove and the clamping hole of the male end correspond to the roller, the roller in the limiting groove at the front end of the locking disk falls into the annular groove, and the roller in the limiting groove at the rear end of the locking disk falls into the clamping hole. Release the outer tube, and the locking spring releases force to drive the outer tube to move forward and reset. The inner wall of the outer tube abuts against the roller, and the roller is limited to the annular groove and the clamping hole, thereby realizing the axial limitation of the male end and the female end.

[0024] 2. After the male end is inserted into the female end, the auxiliary mechanism limits the forward and backward movement of the outer cylinder, and cooperates with the card hole and the roller in the limit groove on the front side to limit the rotation of the male end; after the male end is pulled out of the female end, the auxiliary mechanism drives the locking disk to rotate 180° radially around the female end, so that the positions of the rollers in the two limit grooves on the locking disk are interchanged after each disassembly and assembly, so that the contact parts of the rollers in the two limit grooves on the locking disk and the male end are alternately interchanged, thereby reducing roller wear and extending the service life of the rollers.

When the annular groove 210 and the clamping hole 220 of the male end 200 correspond to the roller 320, the roller 320 in the limiting groove 310 at the front end of the locking disk 300 falls into the annular groove 2 10, the roller 320 in the limiting groove 310 at the rear end of the locking disk 300 falls into the clamping hole 220, the outer cylinder 500 is loosened, the locking spring 400 releases the force to drive the outer cylinder 500 to move forward and reset, the inner wall of the outer cylinder 500 abuts against the roller 320, and the roller 320 is limited to the annular groove 210 and the clamping hole 220, so as to limit the male end 200 and the female end 100 in the axial direction; the clamping hole 220 and the roller 320 in the limiting groove 310 located at the front side are locked and limited, so as to limit the rotation of the male end 200. In this process, the connecting column 663 is at the rear end of the connecting groove 520, the ratchet 620 is received in the receiving groove 630, and the ratchet 610 is out of contact with the groove wall of the wide groove section of the T-shaped groove 510.

[0056] When the outer cylinder 500 moves forward and resets, the outer ring 662 is pushed by hand to overcome the friction between the connecting column 663 and the connecting groove 520, so that the outer ring 662 drives the inner ring 661 to move forward, and drives the piston column 664 to squeeze the gas in the main air channel 652, so that the air pressure in the main air channel 652 and the sub-air channel 651 increases, and drives the push column 640 to approach the ratchet 610, so as to drive the ratchet 620 to rotate around the small end of the ratchet 620 to move away from the receiving groove 630, so that the large end of the ratchet 620 extends out of the receiving groove 630, and the ratchet 610 and the groove wall of the wide groove section of the T-shaped groove 510 are meshed through the ratchet 620. Due to the locking and limiting of the locking hole 220 and the roller 320 in the limiting groove 310 located on the front side, the rotation of the male end 200 around the axis of the male end 200 is limited to limit the rotation of the locking disk 300, and due to the engagement of the ratchet 610 and the ratchet teeth 620, when the locking disk 300 does not rotate, the outer cylinder 500 is limited to move backward through the engagement of the ratchet 610 and the ratchet teeth 620, so that the inner wall of the outer cylinder 500 remains in contact with the roller 320, and the roller 320 is limited in the annular groove 210 and the locking hole 220, thereby realizing double limit locking of the rotation of the male end 200, avoiding the outer cylinder 500 from moving backward due to accidental touch, causing the connection between the male end 200 and the female end 100 to become loose.

[0057] When the male end 200 needs to be pulled out of the female end 100, the outer ring 662 is first moved forward, so that the connecting column 663 overcomes the friction between the connecting column 663 and the connecting groove 520, so that the air pressure in the main air channel 652 and the sub-air channel 651 is reduced, and the push column 640 is driven away from the ratchet 610, so that the ratchet 620 is driven to rotate around the small end of the ratchet 620 to enter the receiving groove 630, so that the large end of the ratchet 620 is received in the receiving groove 630, so that the ratchet 610 and the ratchet 620 are out of contact. Then, the outer cylinder 500 is pushed backward by hand, and the outer cylinder 500 is moved backward to compress the locking spring 400 so that the escape space corresponds to the locking disk 300. When the male end 200 is inserted into the female end 100, the male end 200 pushes the roller 320 to the escape space to pull the male end 200 out of the female end 100. Finally, the outer cylinder 500 is released by hand, and driven by the spring, the outer cylinder 500 moves forward and resets.

[0058] After the male end 200 is pulled out and the outer cylinder 500 is driven forward and reset by the locking spring 400, when the outer cylinder 500 is pushed back again by hand, the outer ring 662 is pushed by hand to overcome the friction between the connecting column 663 and the connecting groove 520, so that the outer ring 662 drives the inner ring 661 forward, drives the piston column 664 to squeeze the gas in the main air channel 652, increases the air pressure in the main air channel 652 and the sub-air channel 651, drives the push column 640 to approach the ratchet 610, drives the ratchet 620 to rotate around the small end of the ratchet 620 to move away from the receiving groove 630, makes the large end of the ratchet 620 extend out of the receiving groove 630, and makes the ratchet 610 and the groove wall of the wide groove section of the T-shaped groove 510 mesh through the ratchet 620. Then, when the outer cylinder 500 is moved back again, the ratchet 620 drives the ratchet 610 to drive the locking disk 300 to rotate 180°.

[0059] Then, the outer ring 662 is moved backward, so that the connecting column 663 overcomes the friction between the connecting column 663 and the connecting groove 520, so that the air pressure in the main air channel 652 and the branch air channel 651 is reduced, and the push column 640 is driven away from the ratchet 610, so that the ratchet 620 is driven to rotate around the small end of the ratchet 620 to enter the receiving groove 630, so that the large end of the ratchet 620 is received in the receiving groove 630, so that the ratchet 610 and the ratchet 620 are out of contact. After releasing the hand, the outer cylinder 500 is driven by the locking spring 400 to move forward and reset.
