Description

Technical Field

[0001] This utility model relates to the field of plate hole protection technology, and in particular to a plate hole sleeve that is easy to install. Background Technology

[0002] A plate hole sleeve is a functional component used to protect holes in sheet metal. It aims to solve many problems faced by plate holes during use, such as preventing them from being physically damaged or chemically corroded. On the outer shell of mechanical equipment, there are often holes for wiring, installing sensors, connecting pipes, etc. Using this plate hole sleeve can protect the holes and prevent dust, oil and other impurities from entering the equipment and affecting its normal operation. At the same time, it facilitates the installation and fixing of various lines, pipes and other components, ensuring the stability and safety of industrial production processes.

[0003] The existing sheath structure is too simple, making it inconvenient to install and use. During use, it is not only easily bent, causing cable wear, but also affecting the performance of the cable.

[0004] An existing patent (publication number: CN216853119U) discloses an easy-to-install tension-type marine guide hole protective sleeve, which can adjust the tension as needed within the guide hole to ensure the stability of the protective sleeve installation within the guide hole and avoid the situation where the protective sleeve cannot be firmly installed due to deformation of the guide hole. It is suitable for the installation of irregular guide holes. The structure of inner and outer tension plates and inner and outer tension openings allows the inner and outer bulwark components to automatically complete the tensioning during docking, which facilitates the completion of tension adjustment.

[0005] To address the aforementioned issues, existing patents offer solutions, but they are not convenient for restricting the circuitry. Once the circuitry passes through the sheath of the plate hole, due to the limitations of its internal structural design, relying solely on the tensioning design makes it difficult to accurately position and securely restrict the circuitry. The circuitry is prone to swaying and shifting freely inside the sheath. Because the restriction effect on the circuitry is poor, the circuitry frequently collides and rubs against the inner wall of the sheath, which may damage the circuitry's outer sheath. This not only affects the circuitry's normal conductivity but may also cause short circuits and other problems after the circuitry's insulation layer is damaged, thus reducing the safety of the device.

[0006] Therefore, a plate hole sleeve that is easy to install is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide an easy-to-install plate hole sleeve, which solves the problem that existing easy-to-install plate hole sleeves are not convenient for restricting the circuit. When the circuit passes through the plate hole sleeve, due to the limitations of its internal structure design, it is difficult to accurately position and securely restrict the circuit by relying solely on the tensioning design. The circuit is prone to shaking and shifting inside the sleeve. Due to the poor restriction effect on the circuit, the circuit frequently collides and rubs against the inner wall of the sleeve, which may damage the circuit sheath. This not only affects the normal conductivity of the circuit, but may also cause short circuits after the insulation layer of the circuit is damaged, thus reducing the safety of the device.

[0026] 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.

[0027] Please see Figure 1-5The present invention provides the following technical solution:

[0028] An easy-to-install plate hole sleeve includes a fixing tube 1, a limiting component 2 is fixedly connected inside the fixing tube 1, and a fixing component 3 is fixedly connected to the top and bottom of the surface of the fixing tube 1. The limiting component 2 includes four arc-shaped plates 201 and four positioning rods 202. Several balls 204 are provided on the opposite side of the four arc-shaped plates 201, and the arc-shaped plates 201 are located inside the fixing tube 1.

[0029] The fixing component 3 includes a fixing ring 301. Fixing blocks 302 are fixedly connected to the four corners inside the fixing ring 301. First springs 303 are fixedly connected inside the fixing blocks 302. Movable plates 304 are fixedly connected to the side of the four first springs 303 away from the fixing tube 1. Pressing blocks 305 are fixedly connected to the side of the movable plates 304 away from the first springs 303.

[0030] In this embodiment: by pressing the pressing block 305, the moving plate 304 is moved smoothly and the first spring 303 is compressed, which releases the fixing effect of the fixing component 3. Under the action of the first spring 303, a reaction force is generated, which drives the moving plate 304 and the pressing block 305 to return smoothly to their original positions, so that the fixing ring 301 and the positioning ring 5 are connected. This allows the fixing tube 1 to be fixed inside the plate hole. At the same time, under the action of the positioning ring 5, the contact area is increased and the external force is dispersed, thereby making the connection of the device more secure and improving the usability of the fixing component 3. For ease of use, the connecting plate 203 is moved smoothly by moving the arc plate 201, which in turn moves the slider 205 smoothly under the restriction of the positioning rod 202 and compresses the second spring 206. This releases the fixing effect of the limiting component 2. At the same time, the second spring 206 can drive the arc plate 201 back to its original position and contact the surface of the line, which can restrict the line of a certain specification. Under the action of the ball bearing 204, the fixed line can be moved, ensuring the safety of the line and preventing the line from being damaged by external forces, thus improving the ease of use of the limiting component 2.

[0031] Specifically, such as Figure 4 As shown, sliders 205 are movably connected to the top and bottom of the surfaces of the four positioning rods 202, and second springs 206 are fixedly connected to opposite sides of the top and bottom sliders 205.

[0032] Specifically, such as Figure 4 As shown, the top and bottom sliders 205 are rotatably connected to the side away from the positioning rod 202 by a connecting plate 203, and the side of the connecting plate 203 away from the slider 205 is rotatably connected to the side of the arc plate 201 near the positioning rod 202.

[0033] Specifically, such as Figure 3As shown, each of the four corners of the inner wall of the fixed tube 1 is provided with a sliding groove 4 for use with the slider 205, and the positioning rod 202 is located inside the sliding groove 4. The two second springs 206 are fixedly connected to the top and bottom of the inner wall of the sliding groove 4 on the side away from the slider 205, and the second springs 206 are sleeved on the surface of the positioning rod 202.

[0034] In this embodiment: the slider 205 works in conjunction with the slide groove 4, allowing the slider 205 to move smoothly inside the slide groove 4 under the restriction of the positioning rod 202 and compress the second spring 206. This releases the fixing effect of the limiting component 2, and under the action of the second spring 206, it generates a reaction force, causing the slider 205 and the connecting plate 203 to return smoothly to their original positions. Simultaneously, it drives the arc plate 201 to move and contact the surface of the circuit, thereby limiting the circuit of a certain specification, ensuring the safety of the circuit, preventing the circuit from being damaged by external forces, and improving the ease of use of the limiting component 2.

[0035] Specifically, such as Figure 5 As shown, a positioning ring 5 is movably connected to the surface of the fixed ring 301, and positioning holes 6 are provided at the four corners of the surface of the positioning ring 5 to cooperate with the pressing block 305.

[0036] Specifically, such as Figure 5 As shown, the four corners of the fixing ring 301 are provided with connecting grooves 7 for use with the fixing block 302, and the surface of the fixing block 302 is in contact with the inner wall of the connecting groove 7.

[0037] In this embodiment: by using the fixing block 302 in conjunction with the connecting groove 7, the surface of the fixing block 302 contacts the inner wall of the connecting groove 7, which makes the fixing block 302 more firmly connected and the pressing block 305 more firmly connected. Then, under the action of the positioning hole 6, the surface of the pressing block 305 contacts the inner wall of the positioning hole 6, which makes the positioning ring 5 more firmly connected. At the same time, under the action of the positioning ring 5, the contact area is increased and the external force is dispersed, which makes the connection between the fixing tube 1 and the plate hole more firmly connected. Thus, the device is more firmly connected and the stability of the device is improved.

[0038] Specifically, such as Figure 1 , Figure 3 As shown, a rubber protective layer 8 is fixedly connected to the surface of the fixed tube 1, and the surface of the rubber protective layer 8 is provided with anti-slip texture.

[0039] Specifically, such as Figure 3 As shown, a partition 9 is provided inside the inner wall of the fixed tube 1, and a buffer material is provided inside the partition 9.

[0040] In this embodiment: the rubber protective layer 8 not only increases the friction between the rubber and the plate hole, making the device more firmly connected, but also absorbs some of the external impact force. At the same time, under the action of the partition layer 9, the interior is filled with buffer material, which can further disperse the external impact force, thus protecting the internal circuit of the fixed tube 1 and improving the safety of the device.

[0041] Working principle: When using the plate hole sleeve, firstly, pressing the pressing block 305 causes the moving plate 304 to move smoothly and compress the first spring 303, which releases the fixing effect of the fixing component 3, allowing the fixing tube 1 to be inserted into the plate hole. Under the action of the first spring 303, it generates a reaction force, causing the moving plate 304 to drive the pressing block 305 into the positioning hole 6, fixing the positioning ring 5 at both ends of the plate hole. At the same time, the positioning ring 5 increases the contact area and disperses external force, making the connection of the device more secure. Then, under the action of the rubber protective layer 8, not only is the friction between the rubber and the plate hole increased, making the connection of the device more secure, but it can also absorb some of the external impact force. The partition 9, filled with cushioning material, further disperses external impacts, protecting the internal circuitry of the fixed tube 1. Finally, by moving the arc-shaped plate 201, the connecting plate 203 moves smoothly, simultaneously causing the slider 205 to move smoothly under the constraint of the positioning rod 202 and compress the second spring 206. This releases the fixing effect of the limiting component 2. Simultaneously, the second spring 206 drives the arc-shaped plate 201 back to its original position, contacting the circuit surface. This ensures that the arc-shaped plate 201 and the ball bearing 204 remain in contact with the circuit surface, restricting circuitry of a certain specification. Furthermore, the ball bearing 204 moves the fixed circuitry, ensuring circuit safety and preventing damage from external forces.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
