Description

Technical Field

[0001] This utility model relates to the field of relay disassembly, specifically a relay safety and quick insertion / removal clamp. Background Technology

[0002] In the rail transit industry, each station's equipment room is equipped with a switch cabinet. The relay contacts within these cabinets, by lifting and lowering, control the signal equipment circuits, thus enabling signal equipment operation. Currently, the relays within these cabinets are arranged quite densely.

[0003] Currently, relay replacement mainly relies on manual operation, which has the following problems: low replacement efficiency, requiring complete disassembly, long time consumption per replacement, easy plastic deformation of relay base contact pieces during insertion and removal, high damage rate, lack of special tools, poor operational safety, and affecting operational safety. Utility Model Content

[0004] The purpose of this utility model is to provide a relay safety quick-plug clamp with reasonable structure, simple operation and suitable for high-density combination cabinet, so as to solve the problems of difficult operation, low efficiency and easy damage of equipment in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a relay safety quick-plug clamp, comprising a handle housing, slide rails installed on both sides of the inner wall of the handle housing, and a fixing arm, the fixing arm being installed at one end of the handle housing, a fixing claw being installed on the end of the fixing arm away from the handle housing, a sliding block being installed inside the slide rail, a rotary bearing being installed on the inner wall of the sliding block, a fixing block being installed on the rotary bearing, a gripping arm being installed at one end of the fixing block, a mounting base being installed at the lower end of the fixing block, a spring hinge being installed on the mounting base, the spring hinge being connected to the mounting base by bolts, and a movable arm being installed at the other end of the spring hinge away from the mounting base.

[0006] Furthermore, the sliding block has second bolt holes at both ends, and the positions of the second bolt holes correspond to the positions of the first bolt holes on the handle housing. The sliding block can be fixed on the handle housing by inserting bolts.

[0007] Furthermore, the outer surface of the handle housing has first bolt holes at both the front and rear ends, which can cooperate with the second bolt holes on the sliding block to fix the sliding block in place.

[0008] Furthermore, sliders are installed at the front and rear ends of the sliding block at corresponding positions on the slide rail. The sliders are slidably connected to the slide rail, and the sliders allow the sliding block to slide back and forth on the slide rail on the inner wall of the handle housing.

[0009] Furthermore, the movable arm is equipped with a movable gripper at the end away from the spring hinge. The movable gripper is bolted to the movable arm. The movable gripper is designed to cooperate with the fixed gripper to clamp the object when the movable arm is tightened.

[0010] Furthermore, rubber anti-slip blocks are installed on the inner sides of both the movable and fixed grippers. The rubber anti-slip blocks can increase the friction between the grippers and the object when the movable and fixed grippers hold the object, thus preventing the object from falling off.

[0011] Furthermore, the movable gripper has a third bolt hole at both the front and rear ends on its outer surface. The third bolt hole is provided so that when the movable arm is bent by the spring hinge, it can be folded into the handle housing, and then the bolt is passed through the first bolt hole and the third bolt hole to fix the movable arm in place, thus completing the storage of the movable arm.

[0012] Furthermore, a handle is mounted on the handle housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model has the following significant advantages: Lever-based force-saving mechanism: The lever mechanism, composed of a sliding block, transmission link, and clamping arm, amplifies the force of the gripping arm and converts it into the clamping force of the clamping arm, making operation more effortless, especially suitable for applying force in narrow spaces. Uniform force distribution and damage prevention: The synchronous linkage design of the double clamping arms ensures that the clamping force is evenly distributed on both sides of the relay, effectively avoiding the distortion and deformation of the base contact piece caused by uneven force, reducing the damage rate to below 1%. Quick alignment and clamping: The guide slope at the front end of the U-shaped contact claw cooperates with the rubber anti-slip pad to quickly enclose the relay and provide sufficient static friction to prevent slippage or detachment during insertion and removal. Integration and portability: All moving parts are integrated into the handle shell, resulting in a compact structure and flat shape. This prevents damage to the mechanism due to misoperation and facilitates direct placement in a tool bag or hanging through the hanging hole. High versatility and maintainability: The modular design allows the clamping arms and U-shaped contact claws to be replaced according to different relay models. The rubber anti-slip pad is a consumable part and can be replaced separately, reducing long-term operating costs. Attached Figure Description

Detailed Implementation

[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] To address the problems inherent in existing relay replacement technology, which relies primarily on manual operation and suffers from low efficiency, requires complete disassembly, is time-consuming per replacement, is prone to plastic deformation of the relay base contacts during insertion and removal leading to a high damage rate, lacks specialized tools, and suffers from poor operational safety, this embodiment provides the following technical solution: Example 1: As Figures 1-4 As shown, the present invention provides a relay safety quick-plug clamp, including a handle housing 1 with slide rails 103 on both sides of its inner wall; a fixed arm 2 is installed at one end of the handle housing 1, with a fixed gripper 201 at its distal end; a sliding block 3 is provided inside the slide rail 103, and the sliding block 3 is slidably connected to the slide rail 103 through sliders 302 installed at both ends. This structure allows the sliding block 3 to move back and forth along the slide rail 103, thereby adjusting the initial distance between the movable arm 404 connected thereto and the fixed arm 2 to accommodate relays of different sizes. The inner wall of the sliding block 3 is equipped with a rotary bearing 303, and a fixed block 4 is installed on the bearing. One end of the fixed block 4 is connected to the grip arm 401, and the other end is provided with a mounting base 402, on which a spring hinge 403 is installed by bolts. The other end of the spring hinge 403 is connected to the movable arm 404, and the distal end of the movable arm 404 is provided with a movable gripper 405. Both the movable gripper 405 and the fixed gripper 201 are provided with rubber anti-slip blocks 407 on their inner sides to increase the gripping friction. The handle shell 1 is also provided with a handle 101 for easy gripping.

[0018] During operation, the operator first pushes the sliding block 3 onto the slide rail 103 according to the size of the relay to be operated, pre-adjusting the opening distance between the movable arm 404 and movable gripper 405 and the fixed arm 2 and fixed gripper 201. Then, by gripping the handle 101 and squeezing the grip arm 401, the operator moves the entire sliding block 3 assembly, which in turn pushes the movable arm 404 towards the fixed arm 2 via the spring hinge 403, allowing the movable gripper 405 and fixed gripper 201 to precisely and securely clamp the relay. The rubber anti-slip block 407 ensures secure clamping and prevents slippage; the clamping force is amplified by the lever mechanism, making operation effortless and the force evenly distributed, effectively preventing deformation of the relay base contact pieces, and achieving safe and quick insertion and removal.

[0019] Example 2: Please refer to Figure 1 - Figure 4 Building upon Embodiment 1, to further enhance the tool's applicability and durability, material upgrades and structural optimizations can be implemented for key components. For example, the fixed gripper 201 and the movable gripper 405 can be made of high-strength aluminum alloy or engineering plastics to reduce weight and enhance wear resistance; the rubber anti-slip block 407 can be made of oil-resistant, high-temperature-resistant silicone rubber or fluororubber to adapt to complex working conditions; the spring hinge 403 can be equipped with a preload adjustment mechanism to facilitate adjustment of the clamping force according to different relay models; in addition, a replaceable gripper module can be provided, enabling quick replacement through a standardized interface and improving the tool's versatility.

[0020] When in operation, its basic operating procedure is the same as in Example 1. Optimization of materials and structure makes this tool suitable not only for conventional relays but also for harsh environments such as high temperatures and oil contamination, significantly extending its service life and reducing maintenance frequency and costs.

[0021] The working principle summarized above is as follows: This specialized tool uses mechanical levers and a linkage gripper mechanism to convert manual pinching force into uniform and stable clamping force, enabling efficient and safe insertion and removal of relays. Its compact structure and simple operation make it suitable for narrow spaces within high-density modular cabinets, effectively avoiding the problems of low efficiency and easy damage associated with traditional manual operation.
