[0001] The utility model belongs to the technical field of live working on distribution lines, and specifically relates to a torque combination type shooting test operating rod. Background Art

[0002] During the live connection of lead wires operation, there is a shooting type locking drainage wire clamp and a matching shooting type operating rod. Through the cooperation of the shooting type locking drainage wire clamp and the shooting type operating rod, the drainage wire clamp of the joint can be disassembled and connected live, thereby reducing the operation intensity of the live working personnel when installing the drainage wire clamp, and improving the safety of live working at the same time.

[0003] After retrieval, CN216699316U discloses a shooting operating rod with a multi-point operating mechanism. By adding a set of operating mechanisms, the problem that the operator cannot unlock the metal hook ring at the upper end is solved. The number of operators is reduced from 3 to 1. Each operation saves an average of 34 minutes of operation time, greatly improving the operation efficiency and reducing the risk of high fall.

[0004] The length of this operating rod cannot be adjusted. When installing the wire clamp, since the heights of the wires are different, the operator needs to carry operating rods of different lengths and sizes when working on wires of different heights, which will greatly affect the portability and practicability of the operating rod.

[0005] In view of this, the present utility model is specifically proposed. Content of the Utility Model

When installing the wire clamp, since the heights of the wires are different, the operator needs to carry operating rods of different lengths and sizes when working on wires of different heights, which will greatly affect the portability and practicability of the operating rod. The basic concept of the technical solution adopted by the present utility model is:

[0007] A torque combination type shooting test operating rod, including an operating rod;

[0008] A grip provided at the bottom end of the operating rod, a combined extension mechanism is provided on the operating rod, and a limit assembly mechanism is provided below the combined extension mechanism. The combined extension mechanism includes a fixed block fixedly connected to the outer wall of the operating rod:

[0009] A cavity is provided inside the fixed block. A first spring is fixedly connected to the inner wall of the cavity. One end of the first spring away from the inner wall of the cavity is fixedly connected to a positioning rod. One end of the outer wall of the positioning rod is fixedly connected to a connecting rod. One end of the outer wall of the connecting rod away from the positioning rod is fixedly connected to a hinge seat. A linkage rod is rotatably connected to the hinge seat. One end of the linkage rod away from the hinge seat is rotatably connected to a rotating shaft. Pressing plates are fixedly connected to the upper and lower ends of the rotating shaft. Grooves are provided on the outer walls of the pressing plates. The rotating shaft is fixedly connected to the inner walls of the grooves. A pressing column is fixedly connected to the outer wall of the pressing plate. A support frame is fixedly connected to the outer wall of the operating rod. A second spring is fixedly connected to the inner wall of the support frame. One end of the second spring away from the inner wall of the support frame is fixedly connected to one end of the pressing column. An extension rod is inserted into the bottom end of the operating rod. Positioning holes are provided on the outer wall of the extension rod. The outer wall of the positioning rod is clamped inside the positioning holes.

[0010] As a preferred embodiment of the present invention, the limiting and assembling mechanism includes a limiting slot provided on the outer wall of the extension rod. An installation slot is provided at the top end of the handle. A plug is fixedly connected to the inner wall of the installation slot. The outer wall of the plug is slidably limited inside the limiting slot.

[0011] As a preferred embodiment of the present invention, the number of the positioning rods is two, and the positioning rods are symmetrically distributed on the left and right outer walls of the operating rod in a left-right symmetrical structure.

[0012] As a preferred embodiment of the present invention, the outer wall of the positioning rod is fitted and matched with the inner wall of the positioning hole, and the bottom end of the outer wall of the positioning rod is provided with an inclined surface.

When the extension rod is inserted, it will contact and squeeze the positioning rod. The squeezed positioning rod will move in the left and right directions. During the movement, it will squeeze the first spring. When the extension rod drives the positioning hole to move to the position of the positioning rod, the first spring can rebound and push the positioning rod into the positioning hole to complete the combined installation of the extension rod. When it is necessary to disassemble the extension rod, the pressure plate can be directly pressed. At this time, the pressure plate will drive the pressure column to move downward and simultaneously squeeze the second spring. When the pressure plate moves downward, it will also drive the linkage rod to rotate through the rotating shaft. At the same time, the end of the linkage rod away from the rotating shaft will rotate with the hinge seat. At this time, the linkage rod will squeeze the connecting rod to move in the left and right directions, so that the connecting rod can drive the positioning rod to move, thereby disengaging from the clamping and limiting with the positioning hole, and thus the extension rod can be disassembled. In this way, extension rods of different lengths can be installed, and the appropriate length can be adapted to wires of different heights for practical use, thereby improving the practicality of the operating rod.

[0018] In the present utility model, after the extension rod is installed, the installation slot opened inside the grip can be aligned with the bottom end of the extension rod, and the position of the insertion strip and the limit slot can be adjusted to correspond. Subsequently, the grip is inserted into the outer wall of the extension rod. At this time, the grip will drive the insertion strip to insert into the limit slot. Since the material of the insertion strip is rubber, a good frictional limiting effect can be formed with the limit slot after insertion and installation, thereby completing the installation operation with the grip.

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model.

[0028] As Figures 1 to 5 shown, a torque combined type shooting gun test operating rod includes an operating rod 1, a grip 2 provided at the bottom end of the operating rod 1, a combined extension mechanism 31 provided on the operating rod 1, and a limit assembly mechanism 32 provided below the combined extension mechanism 31. The combined extension mechanism 31 includes a fixed block 311 fixedly connected to the outer wall of the operating rod 1. A cavity is provided inside the fixed block 311. A first spring 312 is fixedly connected to the inner wall of the cavity. One end of the first spring 312 away from the inner wall of the cavity is fixedly connected to a positioning rod 313. One end of the outer wall of the positioning rod 313 is fixedly connected to a connecting rod 314. One end of the outer wall of the connecting rod 314 away from the positioning rod 313 is fixedly connected to a hinge seat 315. A linking rod 316 is rotatably connected to the hinge seat 315. One end of the linking rod 316 away from the hinge seat 315 is rotatably connected to a rotating shaft 317. Pressure plates 318 are fixedly connected to the upper and lower ends of the rotating shaft 317. Grooves are provided on the outer walls of the pressure plates 318. The rotating shaft 317 is fixedly connected to the inner wall of the groove. A pressure column 319 is fixedly connected to the outer wall of the pressure plate 318. A support frame 3111 is fixedly connected to the outer wall of the operating rod 1. A second spring 3110 is fixedly connected to the inner wall of the support frame 3111. One end of the second spring 3110 away from the inner wall of the support frame 3111 is fixedly connected to one end of the pressure column 319. An extension rod 3112 is inserted into the bottom end of the operating rod 1. Positioning holes 3113 are provided on the outer wall of the extension rod 3112. The outer wall of the positioning rod 313 is clamped in the inner wall of the positioning hole 3113.

[0029] Furthermore, the number of the positioning rods 313 is two. The positioning rods 313 are symmetrically distributed on the left and right outer walls of the operating rod 1 in a left-right symmetrical structure. In this way, the left and right sides of the extension rod 3112 can be supported and stabilized synchronously, thereby improving the installation stability of the extension rod 3112.

[0030] Furthermore, the outer wall of the positioning rod 313 is fitted and matched with the inner wall of the positioning hole 3113. The bottom end of the outer wall of the positioning rod 313 is provided with an inclined surface, so as to ensure the installation stability after the positioning rod 313 is inserted into the inner wall of the positioning hole 3113.

[0031] Furthermore, an installation jack is provided at the bottom end of the operating rod 1. The inner wall of the installation jack is fitted and matched with the outer wall of the extension rod 3112, so as to ensure the tight fit after the extension rod 3112 is inserted into the installation jack, thereby improving the installation stability of the extension rod 3112.

[0032] The limit assembly mechanism 32 includes a limit slot 321 provided on the outer wall of the extension rod 3112. An installation slot 322 is provided at the top end of the grip 2. A plug 323 is fixedly connected to the inner wall of the installation slot 322. The outer wall of the plug 323 is slidably limited on the inner wall of the limit slot 321.

[0033] Furthermore, the number of the limit slots 321 and the plugs 323 is four respectively. The limit slots 321 and the plugs 323 are evenly and equidistantly distributed on the outer wall and the inner wall of the extension rod 3112 and the grip 2. By setting four, the support and fixation can be more uniform on the left and right four sides of the outer wall and the inner wall of the extension rod 3112 and the grip 2, thereby improving the installation stability between the extension rod 3112 and the grip 2.

[0034] Furthermore, the inner wall of the limit slot 321 is fitted and matched with the outer wall of the plug 323. The material of the plug 323 is rubber. In this way, when the plug 323 is inserted and slid on the inner wall of the limit slot 321, it can be closely fitted with the limit slot 321, improving the installation stability with the grip 2. At the same time, by setting the material as rubber, the friction limit between the two can be improved, further improving the installation stability.

[0035] The implementation principle of the torsion combination type shooting gun test operating rod in this embodiment is as follows: When it is necessary to extend the operating rod 1, first align one end of the extension rod 3112 with the installation hole at the bottom end of the operating rod 1 and then insert it. When the extension rod 3112 is inserted, it will contact and squeeze the positioning rod 313. The squeezed positioning rod 313 will move to the left and right directions. During the movement, it will squeeze the first spring 312. When the extension rod 3112 drives the positioning hole 3113 to move to the position of the positioning rod 313, the first spring 312 can rebound and reset to push the positioning rod 313 into the positioning hole 3113 to complete the combined installation of the extension rod 3112. When it is necessary to disassemble the extension rod 3112, the pressure plate 318 can be directly pressed. At this time, the pressure plate 318 will drive the pressure column 319 to move downward and squeeze the second spring 3110 at the same time. When the pressure plate 318 moves downward, it will also drive the linkage rod 316 to rotate through the rotating shaft 317. At the same time, the end of the linkage rod 316 away from the rotating shaft 317 will rotate with the hinge seat 315. At this time, the linkage rod 316 will squeeze the connecting rod 314 to move to the left and right directions. In this way, the connecting rod 314 can drive the positioning rod 313 to move, so as to disengage from the clamping limit with the positioning hole 3113, and thus the extension rod 3112 can be disassembled.

[0036] After the extension rod 3112 is installed, the installation slot 322 opened inside the grip 2 can be aligned with the bottom end of the extension rod 3112 and the position of the insert 323 and the limit slot 321 can be adjusted to correspond to each other. Then, the grip 2 is inserted into the outer wall of the extension rod 3112. At this time, the grip 2 will drive the insert 323 to insert into the limit slot 321. Since the material of the insert 323 is rubber, a good friction limiting effect can be formed with the limit slot 321 after the insertion and installation, so as to complete the installation operation with the grip 2.
