Description

Technical Field

[0001] This application relates to the field of electrical auxiliary tools, specifically a manual low-voltage switch closing assist rod. Background Technology

[0002] The 10kV team at the power supply station is responsible for the operation of the high and low voltage power distribution system in the Capital Airport area, covering a wide range of areas including the flight area, living area, and work area. Due to the very high level of the users, there are many types of low-voltage switches.

[0003] A search revealed patent document CN213781851U, which discloses an electrical auxiliary tool, specifically a low-voltage switch closing assist device. This utility model's low-voltage switch closing assist device includes an operating rod, an insulated transparent protective cover, a lighting unit, a power supply, and an adjustable handle holder. The handle holder is mounted on one end of the operating rod, the lighting unit is mounted on one end of the operating rod, the transparent protective cover is fitted onto the operating rod and located at the end of the lighting unit opposite to the handle holder, and the power supply is mounted on the operating rod and electrically connected to the lighting unit. Advantages: The structure is simple and reasonable, effectively assisting operators in closing low-voltage switches, ensuring operator safety, improving work efficiency, and shortening power outage time.

[0004] In the above devices, the handle holder and the pipe section are fixed, so the angle of the handle holder is fixed and cannot be adjusted, which has certain limitations and poor applicability. Utility Model Content

[0005] The purpose of this application is to provide a manual low-voltage switch closing assist rod, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This application provides a manual low-voltage switch closing assist rod, including an operating rod with an internal cavity. A mounting plate is connected to the operating rod, and a lifting assembly for adjusting the position of the mounting plate is installed inside the operating rod. Two fixing blocks are symmetrically fixed to the lower end of the mounting plate, and a rotating shaft is rotatably connected between the two fixing blocks. A handle gripper is fixedly installed on the rotating shaft. One end of the rotating shaft passes through the side wall of the corresponding fixing block and extends outward and is fixedly connected to a limit plate. The limit plate has a plurality of limit holes evenly spaced in a ring. A limit tube is fixedly connected to the lower end of the mounting plate, and a spring is fixedly connected to the bottom of the limit tube. The other end of the spring is fixedly connected to a limit rod, and the other end of the limit rod passes through the corresponding limit hole.

[0008] By adopting the above technical solution, during use, the handle is clamped by the handle holder, and then force is applied to the handle by the operating lever to complete the closing operation. When it is necessary to adjust the angle of the handle holder, force is applied to the limit rod. The limit rod moves within the limit tube under the force, and the movement of the limit rod compresses the spring, causing the spring to deform under the force. When the limit rod is removed from the corresponding limit hole, the limit plate is rotated. The rotation of the limit plate drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the handle holder to rotate. When the handle holder rotates to the designated position, the limit rod is inserted into the corresponding limit hole to limit the limit plate. Through the above structure, the angle of the handle holder can be adjusted to meet the needs under different conditions, thereby improving the applicability of the device.

[0009] Optionally, the lifting assembly includes a threaded tube rotatably connected to the top of the operating lever, with a threaded rod threadedly connected inside the threaded tube. The other end of the threaded rod passes through the bottom of the operating lever, extends outward, and is fixedly connected to the mounting plate.

[0010] By adopting the above technical solution, when it is necessary to adjust the height of the mounting plate, rotating the threaded tube will cause the threaded tube to exert a force on the threaded rod through the thread action. The threaded rod will move inside the threaded tube due to the force, and the movement of the threaded rod will drive the mounting plate to move. Through the above structure, the distance between the mounting plate and the operating rod can be adjusted to change the magnitude of the torque, thus making it more convenient for users to use.

[0011] Optionally, symmetrical grooves are provided on the inner sidewall of the operating rod, and sliders are slidably connected in the grooves. The other ends of the two sliders pass through the groove openings and extend outwards, and are fixedly connected to connecting blocks. The connecting blocks are fixedly sleeved on the threaded rod.

[0012] By adopting the above technical solution, the threaded rod is limited to prevent it from rotating.

[0013] Optionally, a slide rod is fixedly connected to the inner wall of the chute, the slide rod passes through the slider, and the slider is slidably connected to the slide rod.

[0014] By adopting the above technical solution, the slider is prevented from detaching from the groove.

[0015] Optionally, a rotating block is fixedly connected to the top of the threaded tube.

[0016] By adopting the above technical solution, it is convenient for workers to rotate the threaded pipe.

[0017] Optionally, the operating lever is fitted with an anti-slip sleeve.

[0018] By adopting the above technical solution, it is convenient for users to hold the control stick.

[0019] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0020] (1) The technical solution of this application can adjust the angle of the handle gripper by setting up the operation rod, mounting plate, fixing block, rotating shaft, handle gripper, limiting plate, limiting hole, limiting tube, spring and limiting rod and other structures to meet the needs under different conditions, thereby improving the applicability of the device.

[0021] (2) The technical solution of this application can adjust the distance between the mounting plate and the operating rod by setting up the mutual cooperation between the structure such as threaded pipe, threaded rod, slider and connecting block, so as to change the magnitude of the torque, thereby making it more convenient for users to use.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-6 This application provides a technical solution: a manual low-voltage switch closing assist rod, including an operating rod 1 with an internal cavity, a mounting plate 2 connected to the operating rod 1, a lifting component for adjusting the position of the mounting plate 2 installed inside the operating rod 1, two fixing blocks 3 symmetrically fixedly connected to the lower end of the mounting plate 2, a rotating shaft 4 rotatably connected between the two fixing blocks 3, a handle gripper 5 fixedly installed on the rotating shaft 4, one end of the rotating shaft 4 passing through the side wall of the corresponding fixing block 3 and extending outward and fixedly connected to a limiting plate 6, a plurality of limiting holes 7 evenly spaced in a ring on the limiting plate 6, a limiting tube 8 fixedly connected to the lower end of the mounting plate 2, a spring 9 fixedly connected to the bottom of the inner tube of the limiting tube 8, a limiting rod 10 fixedly connected to the other end of the spring 9, and the other end of the limiting rod 10 passing through the corresponding limiting hole 7.

[0032] In the technical solution of this application, during use, the handle is clamped by the handle holder 5, and the operating lever 1 applies force to the handle to complete the closing operation. When it is necessary to adjust the angle of the handle holder 5, a force is applied to the limit rod 10. The limit rod 10 moves within the limit tube 8 under the force, and the movement of the limit rod 10 compresses the spring 9, causing the spring 9 to deform under the force. When the limit rod 10 is removed from the corresponding limit hole 7, the limit plate 6 is rotated. The rotation of the limit plate 6 drives the rotating shaft 4 to rotate, which in turn drives the handle holder 5 to rotate. When the handle holder 5 rotates to the designated position, the limit rod 10 is inserted into the corresponding limit hole 7 to limit the limit plate 6. Through the above structure, the angle of the handle holder 5 can be adjusted to meet the needs under different conditions, thereby improving the applicability of the device.

[0033] In the technical solution of this application, the lifting assembly includes a threaded tube 11 rotatably connected to the top of the operating lever 1. A threaded rod 12 is threadedly connected inside the threaded tube 11. The other end of the threaded rod 12 passes through the bottom of the operating lever 1 and extends outward and is fixedly connected to the mounting plate 2. When it is necessary to adjust the height of the mounting plate 2, the threaded tube 11 is rotated. The rotation of the threaded tube 11 will apply a force to the threaded rod 12 through the thread action. The threaded rod 12 will move inside the threaded tube 11 due to the force applied. The movement of the threaded rod 12 will drive the mounting plate 2 to move. Through the above structure, the distance between the mounting plate 2 and the operating lever 1 can be adjusted to change the magnitude of the torque, thereby making it more convenient for the user to use.

[0034] In the technical solution of this application, symmetrical grooves are provided on the inner side wall of the operating rod 1, and sliders 13 are slidably connected in the grooves. The other ends of the two sliders 13 pass through the groove openings and extend outwards, and are fixedly connected to connecting blocks 14. The connecting blocks 14 are fixedly sleeved on the threaded rod 12 to limit the threaded rod 12 and prevent the threaded rod 12 from rotating.

[0035] In the technical solution of this application, a slide rod 15 is fixedly connected to the inner wall of the chute, the slide rod 15 passes through the slider 13, and the slider 13 is slidably connected to the slide rod 15 to prevent the slider 13 from detaching from the chute.

[0036] In the technical solution of this application, a rotating block is fixedly connected to the top of the threaded tube 11, which facilitates the rotation of the threaded tube 11 by the operator.

[0037] In the technical solution of this application, the operating lever 1 is fitted with an anti-slip sleeve to facilitate the user's hand grip on the operating lever 1.

[0038] In use, the handle is clamped by the handle holder 5, and force is applied to the handle by the operating lever 1 to complete the closing operation. When it is necessary to adjust the angle of the handle holder 5, force is applied to the limit rod 10. The limit rod 10 will move within the limit tube 8 due to the force. The movement of the limit rod 10 will compress the spring 9, and the spring 9 will deform due to the force. When the limit rod 10 is removed from the corresponding limit hole 7, the limit plate 6 is rotated. The rotation of the limit plate 6 will drive the rotating shaft 4 to rotate, and the rotation of the rotating shaft 4 will drive the handle holder 5 to rotate. When the handle holder 5 is rotated to the designated position, the limit rod 10 is inserted into the corresponding limit hole 7 to limit the limit plate 6.
