Description

Pistol stroke guide

The invention provides a stroke guide rod of a pistol, in particular, in a composite manner, a composite guide rod is formed by axial assembly of a plurality of elements, and a plurality of tension springs are inserted in the axial direction, and the working curves of the plurality of springs are complementary to each other. To substantially eliminate the spurt reaction of bullet firing.

Although the design of the pistol is not far away, but because it is held by the palm end, the resulting rear force, against the grip of the palm and wrist and hand limbs, will still cause the muzzle to move up. The muzzle of the next shot is aimed at the angle. In the new pistol, the rear force can be used to push the sliding sleeve 11 (as shown in Figures 1 and 2), and the moving shell is used to withdraw the shell, and the return stroke synchronously supplies the new bullet. The upper sleeve, the sliding sleeve 11 of the pistol 1 is slid over the barrel, the inside of the sliding sleeve 11 is axially wrapped around the barrel 10, and the lower portion of the barrel 10 is provided with a guiding sleeve 11 on the parallel axis. a single-core conduit 12 that moves linearly in front and rear strokes. The rear end of the single-core conduit 12 is provided with an abutting end 121 for pressing against the rear gear 13 of the gun, and an elastic spring 120 is disposed on the outer sleeve of the single-core conduit 12, and the elastic force is applied. The rear port of the spring 120 is pressed against the opposite end surface of the abutting end 121, the other port is pressed against the opposite end surface of the sliding sleeve 11 connected to the sliding sleeve 11, and the shuttle tube 122 is connected to the sleeve opening 110 of the sliding sleeve 11. Triggering, when the trigger 14 is operated to strike the bullet, due to its blasting pressure, the reverse will slide the sleeve 11 is retracted backward, and the sleeve 110 disposed during the retracting process is to move the shuttle tube 122 backward and backward. During the retracting process, the port of the shuttle tube 122 relative to the spring of the spring spring 120 is a compression spring spring 120. Using the elastic deformation of the spring force spring 120 to obtain The purpose of cushioning, and its force to repel the muzzle from the aiming angle is the positive force generated by the mass velocity when the sliding sleeve 11 is retracted to the final end point, and the sliding sleeve 11 and the wrist grip are generated. Holding the center as the distance of the fulcrum, and the moment force that occurs, even if the muzzle jumps, the process of jumping and the radial deformation force of the spring 120 under compression are the radial driving force at the time of recovery. Mutual interaction is to make the "ζ" or "S" or the angular change of the curvature after the muzzle is fired, which is not conducive to continuous shooting. Before the second shot, the aiming angle of the muzzle is maintained.

The single-core catheter 12 is conventionally used in a single core shape, and its outer circumference is longitudinally pivoted with a spring force spring 120, and the elastic spring 120 generates a strain point P before the maximum compression is formed during the deformation process (see Fig. 3). As shown in the figure, after the strain point P, its elastic response curve will rise upwards, and the lifted section will have a working reaction such as a surge, and a compressive energy storage will be formed, when the external pressure loses a critical moment. The high energy storage, that is, the reverse feedback, is that during the shooting, although the user firmly grips the gun and aligns the muzzle with the target of the shooting, the first firing will be due to the spring spring 120. The elastic curve spur changes, so that the muzzle is offset from the shooting angle. In addition to affecting the direction of the trajectory of the attack, it also affects the aiming operation before the second shot, especially in the competitive course, which greatly affects the shooting frequency and the accuracy of the impact.

In addition, the spring 120 is a spiral tension spring. During the compression process, the spring is rotated in the direction of the spiral body, and the stress transmission action occurs, so that the spring body is twisted and deformed, and the spring waist is deformed. The body is deformed into an "S"-like radial deformation. The force of the radial deformation is a radial force, and there is no available ratio between the axial tension required by the spring body, only the energy consumed. When the pressure is released, because the twisting curve is to be straight, the radial force must be consumed. When the radial force is working, the radial waist of the spring waist will be generated, which affects the aiming orientation of the muzzle.

The conventional single-core catheter 12 cooperates with a single elastic spring 120. After a common shot, the muzzle will change its angular position, and a curve such as a cymbal curve, or at least an arc-shaped jump curve, or a hoop-shaped curve, And the spring deformation of the spring due to compression, the moment of the muzzle displacement, the possibility of eccentricity is extremely likely, this situation is more unfavorable for the second bullet shooting, especially in the shooting game fast shooting situation Next, when the user uses the quasi-center to aim at the correct position and quickly fires, the reaction force will offset the angle of the muzzle, which is not conducive to maintaining the shooting angle during the second shooting, because the angular position of the muzzle will beat. Offset, the shooter must aim at the whole process before shooting the second shot, so that the amount of shots can not be met in one unit of time, and the number of shots and the target hits are common during the time course of the game. Calculated based on the results.

The invention provides a stroke guide rod of a pistol, in particular, in a composite manner, a composite guide rod is formed by axially combining a plurality of elements, and a plurality of springs and a buffer space are installed inside, and the working curves of the plurality of springs are complementary to each other. This makes it a major goal to substantially eliminate the surge reaction generated after firing.

In order to achieve the above object, the composite guide rod system of the present invention is provided with a through shaft, which provides a compression tube axially sliding, and the outer end of the pressure tube is supported by a sliding rod, so that the pressure tube shaft can be Maintaining the centerline activity of the system, the axial coupling between the components is achieved by connecting the shaft end of the connecting rod with the end of the connecting shaft provided by the mandrel, and the outer surface of the sliding rod 4 and the pressing tube are coaxially combined.

The third object of the present invention is to provide a plurality of stagnation grooves arranged in an equiangular longitudinal direction at the front end of the slide bar, and the stagnation groove can provide a damping between the contact surfaces of the shuttle pipe when sliding. The system stroke speed is responsive.

The fourth object of the present invention is that the composite guide rod is formed by a multi-element shaft type, and the front and rear elements are in a single working axis, and each of them can be radially interacted with each other.

There is a locking portion 212, which can be a screw. The end of the connecting shaft 211 is at least a screw portion, and the locking hole 42 is fixedly coupled to the axial direction of the rear end of the sliding rod 4, and the above pressure is applied. The movable tube 3 has an inner abutment ring 31 at its shoulder, and a shaft hole 310 is disposed in the center of the inner abutment ring 31. The shaft hole 310 is in sliding tolerance with the connecting shaft 211 and is separated by the inner ring 31. The inner circumference of the rear section of the pressure tube 3 forms a set of cylinders 32. The diameter of the sleeve cylinder 32 is matched with the outer circumference of the mandrel 21, and is separated by the inner ring 31. The front end forms a sliding cylinder 33. The inner circle of the sliding cylinder 33 provides sliding of the sliding shaft 41 contracted by the rear portion of the sliding rod 4, and forms a tolerance fit of the sliding, and The outer diameters of the pressure tube 3 and the slide rod 4 are equal to allow the shuttle tube 122 to slide longitudinally.

An expansion ring 34 is formed on the rear end of the pressure tube 3, and a first spring 20 is axially disposed between the expansion ring 34 and the opposite end surface of the abutting end 121. A port of the first spring 20 is crimped against The inner end surface of the end 121 is crimped to the opposite end surface of the expansion ring 34. The second spring 30 has a larger diameter than the connecting shaft 211, and the outer diameter is smaller than the coil spring of the socket cylinder 32, and one port is crimped to the connecting shaft. The end surface of the corner between the 211 and the mandrel 21 is crimped to the opposite end surface of the inner ring 31. A third spring 40 has a larger diameter than the outer diameter of the pressure tube 3, and one end is crimped to the expansion ring 34. The other end is crimped to form an arch relationship at the bottom end surface of the shuttle tube 122.

The pressure tube 3 is bounded by the connecting shaft 211 of the mandrel 21 to the longitudinal direction of the sliding rod 4, and the maximum outward displacement dimension of the pressing tube 3 is offset by the end surface of the sliding shaft 41 provided in the rear section of the sliding rod 4. The opposite end faces of the 31 are restricted, so that the pressure tube 3 does not rush out, and the sliding cylinder 33 provided in the pressure tube 3 is generally a thin cylinder, so that the length of the sliding cylinder 33 is smaller than that of the sliding shaft 41. In the length, the outer port of the sliding cylinder 33 does not touch the engaging angular end 400 of the sliding shaft 41 and the sliding rod 4, so that the sliding cylinder 33 structure is not subjected to longitudinal punching damage at any stroke, and the connecting shaft 211 is deep. The locking hole 42 is disposed in the axial direction of the rear end of the sliding rod 4, and the locking portion 212 is provided as a spiral, which can pass through the deep position of the sliding rod 4 and the angular end 400 of the sliding shaft 41, and the locking hole is The female thread of 42 avoids the radial position of the corner end 400 described above, so that the structure does not have a weak point at the position of the corner end 400.

The front end of the slider 4 is located at the front of the shuttle tube 122, and a plurality of stagnation grooves 43 are arranged in the longitudinal direction of the radial direction. The stagnation groove 43 can provide the shuttle tube 122 to slide. At the same time, the damping between the contact interfaces of the two is reduced, the stroke speed of the system is sensitive, and the surface thereof is grease-lubricated, and the concave of the hysteresis groove 43 is utilized to facilitate the pinching of the fingers to disassemble the sliding rod 4 and the piercing shaft 2 The relationship between the two.

Linkage The sleeve 110 is pulled, and when the sleeve 11 is retracted as shown in FIG. 2, the shuttle tube 122 is moved backward, the root end surface of the shuttle tube 122 compresses the third spring 40 relative to the port, and the third spring 40 is slid. The compression of the bobbin 122, the elastic reaction force acts on the expansion ring 34 of the pressure tube 3, and drives the pressure tube 3 to move backwards, and the power of the pressure tube 3 to be retracted is the third spring 40 first. The rearward compression force of the shuttle tube 122 is greatly absorbed, so that the third spring 40 is simultaneously transmitted to the expansion point 34 before the point of the strain point P as shown in FIG. 3, and the expansion ring 34 drives the pressure tube 3 as a whole. At the same time, the inner ring 31 of the pressure tube 3 compresses the second spring 30 at the same time. During the process, the pressure tube 3 also compresses the first spring 20 between the abutting end 121 and the expansion ring 34 while being retracted. The maximum power of the compression stroke is absorbed by the third spring 40. When the third spring 40 reaches the position of the strain point P, the force is not pressed by the inner ring 31 to press the second spring 30, and the expansion is utilized. When the ring 34 presses the first spring 20, the second spring 30 and the first spring 20 are simultaneously deformed, so their working curves At the same time, with the aid of the second spring 30, the elastic stress setting of the first spring 20 can be reduced, the elastic modulus of the first spring 20 can be reduced, and the complementary effect between the first spring 20 and the second spring 30 is formed. The two springs 30 share the reaction force of the first spring 20, provided that the elastic response curve of the third spring 40 is received, and after the third spring 40 is subjected to the compression deformation threshold, the first spring 20 and the second spring 30 bear the third spring 40. The deformation stress, after the impact of the bullet, the sliding sleeve 11 is retracted to form a complementary absorption by the elastic reaction of the third spring 40 and the first spring 20 and the piercing shaft 2, so that the maximum reaction force of the bullet can be eliminated, so that the gun can be maintained. The orientation of the mouth is maintained, and the elastic pressure response of the device can be sequentially set to the first spring 20 > the second spring 30 > the third spring 40.

The displacement length of the expansion ring 34 is finally determined by the second spring 30. When the second spring 30 is pressed by the inner ring 31 to reach the compression length limit of the second spring 30, the expansion ring 34 does not eventually collide. The opposite end faces of the abutting ends 121 do not have mechanical impact forces to maintain the stability of the system operation.

The sliding bar 4 is a solid body (as shown in FIG. 7), and a guard cone 5 can be coupled to the outer port thereof. The defensive cone 5 is the same as the sliding bar 4, or is coaxially combined by a locking method. When the defensive cone head 5 is used for close defense, during the gangster's wrestling process, the use of the defensive cone 5 can sting the body surface of the gangster, causing pain and achieving the purpose of stagnation.
