[0002] With the development and changes of war, light off-road vehicles with strong mobility are used as mobile platforms, and fire suppression weapons are installed on them to meet the rapid mobility of infantry firepower. Most of the weapons installed on them are shoulder-mounted. In terms of weapon use, in order to ensure the operability of the weapons and meet the operation and use of different personnel, a weapon lifting mechanism with adjustable height is designed on the gun rack. At present, most gun racks installed on armored vehicles, tanks or ships are not designed with weapon lifting mechanisms that can adjust the height. Even if there are lifting mechanisms, they are all more parts and more complicated, which is very inconvenient to repair. Summary of the invention

[0004] The purpose of the utility model is achieved in this way:

[0005] A weapon lifting mechanism capable of adjusting height comprises an upper frame, a vertical axis component, and a lifting handle. The upper frame is used to install a gun body. A lifting tube extending downward is provided at the bottom of the upper frame. A guide strip is axially provided on the lifting tube. The vertical axis component has a guide cylinder. The lifting tube is slidably fitted in the guide cylinder. A guide groove is provided in the guide cylinder corresponding to the guide strip to form circumferential positioning of the lifting tube. A threaded cylinder is provided at the bottom of the lifting tube. A lifting rod is installed at the bottom of the guide cylinder through a bearing. The lifting rod has threads. The lifting rod and the threaded cylinder cooperate to form a screw nut mechanism. The lower end of the lifting rod passes through the vertical axis component and is connected to the lifting handle.

[0006] Preferably, the lifting handle includes a latch, a crank, a lifting release push rod, a release reset spring, and a handle part.

The lifting release push rod has a stepped inner hole, and the handle part is sleeved on the lower part of the lifting release push rod. The latch is slidably fitted in the stepped inner hole of the lifting release push rod. The lower end of the latch passes through the lifting release push rod and is fixedly connected to the handle part. The latch is a stepped shaft. The release reset spring is sleeved on the latch. The two ends of the release reset spring act on the step surface of the latch and the step surface of the inner hole of the lifting release push rod respectively. A plurality of positioning holes are provided at the bottom of the guide cylinder of the vertical shaft component along the circumferential direction. Under normal circumstances, the latch extends out of the lifting release push rod and is inserted into a positioning hole for positioning.

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0023] A weapon lifting mechanism capable of adjusting height comprises an upper frame 1, a direction locking clamp assembly 2, a vertical shaft component 3, and a lifting handle 4. The upper frame 1 is used to install a gun body. A lifting tube 101 extending downward is provided at the bottom of the upper frame 1. A guide strip 102 is axially provided on the lifting tube 101. The vertical shaft component 3 has a guide cylinder 301. The lifting tube 101 is slidably matched in the guide cylinder 301. A guide groove is provided in the guide cylinder 301 corresponding to the guide strip 102 to form circumferential positioning of the lifting tube 101. A threaded cylinder 103 is provided at the bottom of the lifting tube 101. A rotatable lifting rod 5 is installed at the bottom of the guide cylinder 301 through a bearing (GB / T301-1995). The lifting rod 5 has threads. The lifting rod 5 and the threaded cylinder cooperate to form a screw nut mechanism. The lifting rod is used to adjust the lifting of the upper frame. The lower end of the lifting rod passes through the vertical shaft component 3 and is connected to the lifting handle 4.

[0024] The lifting handle 4 includes a latch 7, a crank 8, a lifting release push rod 9, a release reset spring 10, and a handle portion 11. One end of the crank 8 is fixedly connected to the lower end of the lifting rod (threaded fit), and the other end of the crank 8 is fixedly connected to the lifting release push rod 9 (threaded fit, or clearance fit axial limit). The lifting release push rod 9 has a stepped inner hole, and the handle portion 11 is sleeved on the lower part of the lifting release push rod 9. The latch 7 is slidably fitted in the stepped inner hole of the lifting release push rod 9. The lower end of the latch 7 passes through the lifting release push rod 9 and is pin-connected with the handle portion 11. The latch 7 is a stepped shaft. The release reset spring 10 is sleeved on the latch 7. The two ends of the release reset spring 10 act on the step surface of the latch 7 and the step surface of the inner hole of the lifting release push rod 9 respectively. When the crank 8 and the handle portion 11 collide, the latch 7 extends out of the lifting release push rod 9. The bottom of the guide cylinder 301 of the vertical shaft component 3 is provided with a plurality of positioning holes along the circumferential direction. The latch 7 is used to be inserted into a positioning hole for positioning. The latch pin 7 is sleeved with a shift fork 12, which is used to pull the latch pin 7 downward to make the latch pin 7 escape from the positioning hole. The upper part of the guide cylinder 301 of the vertical shaft component 3 is sleeved with a direction locking clamp assembly, which is used to lock the lifting tube 101 and the guide cylinder 30.

[0025] Example: See Figure 1 — Figure 8 .

[0026] The height adjustable mechanism is composed of an upper frame, a direction locking clamp assembly, a vertical shaft component, a lifting handle, a lifting rod, etc. The upper frame is mainly used to install the gun body, installed in the vertical shaft component, and connected to the lifting rod through a thread; the lifting rod is used to adjust the lifting of the upper frame, passes through the vertical shaft component, and is connected to the lifting handle; the lifting handle is composed of a latch 7, a crank 8, a lifting release push rod 9, a release reset spring 10, a handle part 11, a fork 12, etc., and is connected to the lifting rod. Press the fork down and hold the handle part 11 by hand, turn the handle part 11 clockwise or counterclockwise, drive the lifting rod to rotate, and make the upper frame move up or down through thread transmission to achieve the lifting effect; the direction locking clamp assembly is mainly used to lock the upper frame. When locked, the upper frame cannot move up or down or rotate in the direction.

[0027] Press down the fork 12 on the lifting handle 4 and hold the handle 11 with your hand. The fork 12 drives the handle 11 to move downward, and the handle 11 drives the latch 7 to move downward, so that the latch 7 is separated from the positioning hole of the vertical shaft component 3. Rotate the handle 11 clockwise or counterclockwise to drive the lifting rod 5 to rotate, and move the upper frame 1 upward or downward through the thread transmission to achieve the purpose of lifting. After adjusting to the appropriate position, release the handle 11, and the latch 7 will reset under the action of the release reset spring 10 and enter the positioning hole of the vertical shaft component 3 for positioning; pull the locking handle 15 on the direction locking clamp assembly 2 upward to drive the direction locking screw 14 to rotate, so that the direction clamp 13 shrinks inward, so as to achieve the purpose of locking the upper frame 1 and prevent rotation and up and down movement.

[0028] The lifting rod is connected to the bracket. After the connection is completed, install the bracket in the vertical shaft component and install the lifting handle on the lifting rod.

[0029] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
