Description

Technical Field

[0001] This utility model relates to the field of mine-clearing anchor technology, specifically a telescopic mine-clearing anchor. Background Technology

[0002] A mine-clearing anchor is a device used to pull out or detonate landmines during manual mine clearance after war. It is commonly used to detect tripwire mines hidden in bushes and to retrieve mines in the water. The mine-clearing anchor is a key support and traction tool in mine-clearing operations and is frequently used in mine-clearing operations.

[0003] Existing mine-clearing anchors mostly have their top claws directly welded to the anchor rod, and the anchor rod as a whole is not easy to extend or retract, resulting in a large size of mine-clearing anchors that are inconvenient to carry. Therefore, we propose a telescopic mine-clearing anchor. Utility Model Content

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A telescopic mine-clearing anchor includes: a mine-clearing anchor rod and a telescopic assembly; the telescopic assembly includes a rotating shaft seat fixedly installed at the top of the mine-clearing anchor rod, anchor claws rotatably connected in the rotating shaft seat, a locking block fixedly installed at one end of each anchor claw, grooves arranged on the mine-clearing anchor rod, springs fixedly connected between the anchor claws and the grooves, a restraining sleeve movably sleeved on the outer end of the mine-clearing anchor rod, a threaded hole opened in the lower part of the mine-clearing anchor rod, and a screw movably installed in the threaded hole.

[0007] Preferably, a nut is also fixedly installed at the bottom of the restraint sleeve, and the nut is installed at the outer end of the mine-sweeping anchor rod.

[0008] Preferably, the lower part of the mine-clearing anchor rod is also provided with an external thread, and the nut is matched and connected to the external thread.

[0009] Preferably, the inner side of each anchor claw is also provided with spikes.

[0010] Preferably, a fixing lug is also fixedly installed at the bottom of the screw.

[0011] Preferably, a stop block is also fixedly installed on the top of the mine-clearing anchor rod.

[0012] Preferably, the number of the rotating shaft seat, anchor claw, locking block, groove and spring are all four sets.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, the anchor claws arranged and installed at the top of the mine-clearing anchor rod and the screw installed in the threaded hole at the bottom can be retracted into the inner side of the binding sleeve and the threaded hole, respectively, thereby reducing the overall size of the mine-clearing anchor and improving its portability. At the same time, the anchor claws and screws at the top and bottom of the mine-clearing anchor rod can also be easily retracted and extended by rotation and pinching, thereby improving the adjustment convenience of the mine-clearing anchor.

[0015] 2. In this utility model, the retracted mine-clearing anchor has no exposed sharp parts on the outside, which can also ensure safety during carrying. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a telescopic mine-clearing anchor.

[0024] Example 1:

[0025] Combination Figure 1-3As shown, the present invention provides a telescopic mine-clearing anchor, comprising: a mine-clearing anchor rod 100 and a telescopic assembly 200; the telescopic assembly 200 includes a rotating shaft seat 201 fixedly installed on the top of the mine-clearing anchor rod 100, anchor claws 202 rotatably connected in the rotating shaft seat 201, a locking block 203 fixedly installed at one end of each anchor claw 202, grooves 204 arranged on the mine-clearing anchor rod 100, springs 205 fixedly connected between the anchor claws 202 and the grooves 204, a restraining sleeve 206 movably sleeved on the outer end of the mine-clearing anchor rod 100, and a threaded hole 207 opened in the lower part of the mine-clearing anchor rod 100. A screw 208 is movably installed in the threaded hole 207. A nut 209 is fixedly installed at the bottom of the restraining sleeve 206 and is installed at the outer end of the mine-clearing anchor rod 100. The lower part of the mine-clearing anchor rod 100 is also provided with an external thread 210, and the nut 209 is matched and connected with the external thread 210. Spikes 211 are arranged on the inner side of the anchor claw 202. A fixing ear 212 is fixedly installed at the bottom of the screw 208. A stop block 213 is fixedly installed at the top of the mine-clearing anchor rod 100. There are four sets of rotating shaft seat 201, anchor claw 202, locking block 203, groove 204 and spring 205.

[0026] Specifically, a mine-clearing anchor is a device used to pull out or detonate landmines during post-war manual mine clearance. The anchor claws 202 arranged at the top of the anchor rod 100 and the screw 208 installed in the threaded hole 207 at the bottom can be retracted into the inner side of the restraining sleeve 206 and the threaded hole 207, respectively, thereby reducing the overall size of the mine-clearing anchor and improving its portability. Simultaneously, the anchor claws 202 and screw 208 at the top and bottom of the mine-clearing anchor rod 100 can be easily retracted and extended by rotation and pinching, improving the adjustability of the mine-clearing anchor. Furthermore, the retracted mine-clearing anchor has no exposed sharp parts, ensuring safety during transport. The rotating shaft seat 201 arranged at the top of the mine-clearing anchor rod 100, as well as the anchor claws 202 and the groove... The spring 205 installed between 204 is mainly used for the rotation and opening or pinching and closing of the anchor claw 202. The locking block 203 at one end of the anchor claw 202 is mainly used to bind the anchor claw 202 into the binding sleeve 206 after it is pinched and closed. The nut 209 installed at the bottom of the binding sleeve 206 is mainly used to move the binding sleeve 206 at the outer end of the mine sweeping anchor rod 100. The spikes 211 arranged on the inner side of the anchor claw 202 are mainly used to improve the gripping effect of the anchor claw 202 during traction. The fixing lug 212 installed at the bottom of the screw 208 is mainly used to connect the wiring harness during the use of the mine sweeping anchor. The stop block 213 fixedly installed at the top of the mine sweeping anchor rod 100 is mainly used to limit the opening and closing degree of the anchor claw 202, thereby ensuring a good hooking and traction effect of the anchor claw 202.

[0027] Working principle and usage process of this utility model:

[0028] When the mine-clearing anchor is not in use, first pinch the four anchor claws 202 at the top of the mine-clearing anchor rod 100 so that the anchor claws 202 rotate inward along the rotating shaft seat 201 and compress the spring 205 at the inner end. When the locking blocks 203 at one end of the anchor claws 202 are all pinched to the outer wall of the mine-clearing anchor rod 100, the nut 209 at the outer end of the mine-clearing anchor rod 100 can be rotated to move the binding sleeve 206 at its top upward so that the binding sleeve 206 moves upward to bind to the outer end of the locking block 203. Then, screw the screw 208 at the bottom of the mine-clearing anchor rod 100 inward so that the screw 208 is screwed into the threaded hole 207, and the mine-clearing anchor can be closed.

[0029] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
