Description
Technical Field
The invention relates to the technical field of firearms, in particular to a machine gun tripod high-low steering gear.
Background
The tripod 200 of the machine gun 300 is used for stably controlling the height and direction angle of the firearm, and the height and direction of the firearm need to be roughly adjusted in the shooting process, namely, rough aiming, so that the firearm points in the target direction. The gun's aiming system is then precisely pointed at the target by fine adjustment of the height and direction, i.e., fine aiming. After aiming is completed, the height and direction are locked.
The rough aiming and the fine aiming of the prior gun rack are respectively realized by two sets of mechanisms, and the rough aiming is realized by directly adjusting the direction angle of a gun rack bracket and the height angle of a cradle. After rough aiming is finished, the height and the direction are generally fixed, and then fine aiming is carried out. The tight fixing of the high-low direction angle is generally formed by two independent locking handles, the two locking handles are far away, and rough aiming of the high-low direction and the tight fixing of the locking handles are required to be completed respectively. Also, when the height and the direction angle are required to be loosened, the operation is required to be performed respectively, and the operation process is complicated. The fine sight is typically achieved by a specially configured fine sight mechanism, and some machine guns 300 are not configured with a fine sight mechanism. The stroke of the fine sighting device 200 of the machine gun 300 in China is generally smaller, and only the high and low angles of the weapon can be adjusted. When the fine aiming stroke is insufficient, only the locking handle can be loosened to re-perform coarse aiming, and then the locking handle is tightly fixed to perform fine aiming, so that the fine aiming device is inconvenient to use.

Detailed Description
Referring to fig. 1-11, an embodiment of a three-leg high and low steering machine for a machine gun is shown.
The high-low steering gear 100 is installed behind the tripod 200, the cross brace 104 is connected with the left leg and the right leg of the tripod 200, and the vertical brace 105 is connected with the machine gun 300 or the tripod 200 cradle. The clearance between the cross brace 104 and the gun rack should be as small as possible after installation, but the cross brace 104 can rotate about its own axis. As shown in fig. 1.
The height direction machine 100 is divided into a height machine controlling the height and a direction machine controlling the direction. The height machine and the direction machine share a shell, and are arranged in a front-back mode. The vertical support 105 and the horizontal support 104 are installed in the vertical steering gear housing 101 in a mutually perpendicular spatial relationship, as shown in fig. 2.
A left lock piece 108, a middle lock piece 109, a right lock piece 110, a lock leaf spring 111, a release 112, a middle lock piece return spring 113 and a lock piece rotating shaft 114 are installed in the housing. One end of the left lock piece 108 and one end of the right lock piece 110 are installed in a notch 122 (shown in fig. 9) of the lock piece rotating shaft 114, and can rotate around the axis of the lock piece rotating shaft 114 as a circle center and also can slide relative to the notch 122 of the lock piece rotating shaft 114. The other ends of the left lock piece 108 and the right lock piece 110 are provided with lock leaf springs 111, and the lock leaf springs 111 always push the lock pieces to the center direction. The middle lock piece 109 is installed at the center of the left lock piece 108 and the right lock piece 110, and is kept at a neutral position by two middle lock piece return springs 113, and when the middle lock piece 109 deviates from the original position due to external force, the middle lock piece return springs 113 can return the middle lock piece 109 to the original position. The vertical support 105 and the horizontal support 104 pass through square holes 117 of the left locking plate 108, the right locking plate 110 and the middle locking plate 109, as shown in fig. 6 and 7. The square hole 117 has a height dimension slightly larger than the height dimension of the vertical brace 105 and the horizontal brace 104. The release 112 is mounted above the middle lock piece 109 so as to be rotatable about its own axis and also to move forward and backward in the axial direction, as shown in fig. 3 and 5. The release pivot shaft 125 is hinged to the direction adjustment handle 107 through the release spring 115 and the steering cover 102. When the release 112 moves back and forth, the release spring 115 can restore the release 112 to its original position as shown in fig. 5. Two spring wires arranged above the releaser 112 are the releaser return springs 124, a screw connected with the casing direction machine cover 102 is arranged in the middle of the releaser return springs 124, when the releaser 112 rotates under the action of external force, the releaser return springs 124 are contacted with the screw and deform, and after the external force is removed, the releaser return springs 124 reset the releaser 112. As shown in fig. 8 and 11.
Because the structure and principle of the high-low machine and the steering machine are completely consistent, the high-low machine rotates the steering machine by 90 degrees, and the steering machine is taken as an example to explain the action principle of the mechanism.
When no external force exists, the left locking plate 108 and the right locking plate 110 deflect to the center by a certain angle under the action of spring force, and the upper edge and the lower edge of the square hole 117 are contacted with the cross brace 104 or the vertical brace 105 to clamp the cross brace 104. When the firearm has a trend of rightward movement, the shell drives one end of the right locking plate 110 matched with the rotating shaft through the locking plate rotating shaft 114, so that the trend of the locking plate to swing towards the center is aggravated, the cross brace 104 is further distinguished, and the trend of rightward movement of the shell is limited. Similarly, left locking tab 108 limits the tendency of the housing to move to the left. Therefore, the housing cannot move leftwards or rightwards at this time, and the steering gear is in a locked state.
The direction adjustment handle 107 is currently pushed or pulled back. The direction adjusting handle 107 drives the release device 112 to move backwards, the release inclined surface 121 contacts with the release inclined surfaces 119 on the left lock plate 108 and the right lock plate 110 in the backward movement process of the release device 112, and pushes the left lock plate 108 and the right lock plate 110 to two sides, at this time, gaps are generated between the left lock plate 108, the right lock plate 110 and the cross brace 104 in the height direction, the state that the left lock plate 108 and the right lock plate 110 are blocked by the cross brace 104 is released, and at this time, the high-low steering gear 100 can freely move left and right on the cross brace 104, as shown in fig. 10. At this time, the gun can be operated to conduct rough aiming. Similarly, the height adjusting handle 106 is pulled forward and backward to perform rough aiming. The two handles can be operated independently or together. Because the distance between the direction adjusting handle 107 and the height adjusting handle 106 is relatively short, a shooter can pinch the two handles simultaneously, the height adjusting handle 106 is in a back pulling state, the direction adjusting handle 107 is in a forward pushing state, the height and the direction can be simultaneously released, and rough aiming in the height and the direction can be simultaneously performed. After the height adjusting handle and the direction adjusting handle 107 are released, the release device 112 is reset under the action of the release spring 115, the release inclined surface 119 is released, and the left locking plate 108 and the right locking plate 110 are reset under the action of the locking plate spring 111 to lock the cross brace 104 in the height and direction.
When the direction fine aiming is needed, the direction adjusting handle 107 is pulled up and down, the direction adjusting handle 107 rotates, and the rotation of the adjusting handle drives the release device 112 to rotate. Since the upper end of the middle lock piece 109 is mounted in the notch 122 of the release 112, the release 112 also drives the middle lock piece 109 to rotate. After the middle lock piece 109 rotates a certain angle, it is locked with the cross brace 104, and at this time, the middle lock piece 109 and the cross brace 104 can be regarded as a whole. While the release 112 rotates, the fine aiming release surface 123 contacts with the lock piece on one side to push the lock piece on one side open. If the direction adjusting handle 107 is pulled downwards, the release device 112 rotates clockwise, and the upper end of the middle lock piece 109 swings rightwards to enable the middle lock piece 109 to be blocked on the cross brace 104, and meanwhile, the fine aiming release surface 123 of the release device 112 pushes the left lock piece 108 open. Continuing to pull down the direction adjustment handle 107, the release 112 is supported by the middle lock piece 109, which drives the entire high-low steering gear 100 to move to the left as shown in fig. 11. Because the length of the direction adjusting handle 107 is far longer than the distance from the notch 122 of the release 112 to the rotating shaft, the direction adjusting handle 107 needs to be pulled for a large stroke, and the whole high-low steering gear 100 can only move leftwards for a short distance, so that accurate direction adjustment, namely fine aiming, is realized. After the direction adjusting handle 107 is released, the release 112 is reset under the action of the reset release return spring 124 and drives the direction adjusting handle 107 to reset, and the left locking plate 108 is reset under the action of spring force and is used for clamping the cross brace 104 again. The middle lock tab 109 is also restored to the neutral position by the middle lock tab return spring 113. When the fine aiming stroke is insufficient, the handle is loosened, and the handle is pulled again, so that continuous fine aiming can be realized.
The direction adjusting handle 107 is pulled upwards in the same way, and the fine sighting device moves rightwards. The height adjustment handle 106 is pulled downward, the cradle or gun 300 is moved downward, and the gun 300 is moved upward by pulling the height adjustment handle 106 upward.
Finally, it is noted that the above-mentioned preferred embodiments are only intended to illustrate rather than limit the invention, and that, although the invention has been described in detail by means of the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
