Description
Technical Field
[0001] This utility model relates to the field of cable protection devices, and in particular to a cable protection sleeve that is easy to install. Background Technology
[0002] A cable is a device used to transmit electrical energy or signals. It typically consists of an internal conductor bundle and an external highly insulating layer. Cables are widely used in power systems, information transmission systems, and instrumentation systems. As an indispensable component of power transmission and communication systems, cable protection sleeves provide necessary mechanical protection and environmental isolation for cables, preventing them from physical damage and environmental corrosion. This helps extend the service life of cables and ensures the stability and reliability of power and communication networks.
[0003] Currently, protective sleeves generally consist of two parts that wrap around the cable from both sides. These two parts are usually fixedly connected by bolts. However, bolted connections often require tools to tighten each bolt individually, which can be inefficient in confined spaces or at heights. Furthermore, in humid environments, the bolt connections can easily rust, making disassembly difficult. In addition, to accommodate the thermal expansion and contraction of the cable, the inner diameter of the sleeve is usually larger than the outer diameter of the cable. This can lead to relative slippage between the cable and the sleeve, potentially causing the cable protective sleeve to shift position and ultimately affecting its protective function for the cable.
[0004] Therefore, those skilled in the art have provided a cable protection sleeve that is easy to install in order to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an easy-to-install cable protection sleeve. This sleeve allows for rapid installation and ensures the relative stability between the cable and the sleeve.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] An easy-to-install cable protection sleeve includes a cable body, two main sleeves, two No. 1 connecting blocks, and four waterproof plugs. The outer surfaces of the two main sleeves are provided with grooves near their upper and lower ends. Limiting blocks are slidably fitted onto the upper and lower ends of the two main sleeves. Slider blocks are fixedly installed on the inner surfaces of the two No. 1 connecting blocks near their upper and lower ends. Second connecting blocks are fixedly installed at the upper and lower ends of the two No. 1 connecting blocks. Grooves are provided at opposite ends of each pair of the four No. 2 connecting blocks. Limiting grooves are provided near the front and rear ends of each pair of the four No. 2 connecting blocks. Spring telescopic rods are fixedly fitted onto opposite sides of each pair of the four No. 2 connecting blocks. Arc-shaped clamps are fixedly installed at opposite ends of each pair of the four spring telescopic rods.
[0008] Furthermore, the two main sleeves are respectively fitted on both sides of the cable body, and the cable body is fitted between the four waterproof plugs in pairs.
[0009] Furthermore, the four limiting blocks are all connected to the two main body sleeves by springs, and the four limiting blocks are respectively engaged in the eight limiting slots.
[0010] Furthermore, the two connecting blocks are slidably fitted onto the outer surfaces of the two main body sleeves, and the four sliders are slidably fitted into the four grooves.
[0011] Furthermore, four waterproof plugs are respectively fitted into four No. 2 connecting blocks, and the outer surfaces of the four waterproof plugs are respectively fitted into four grooves near the upper end.
[0012] Furthermore, the inner surfaces of the four waterproof plugs are respectively fitted onto the outer surfaces of the four arc-shaped clamps near their lower ends, and the four arc-shaped clamps are respectively fitted onto the outer surfaces of the cable body near their upper and lower ends.
[0013] Furthermore, each of the four arc-shaped clamps is fixedly provided with an elastic pad on one side opposite to each other, and the four elastic pads are respectively fitted on the outer surface of the cable body near the upper and lower ends.
[0014] This utility model has the following beneficial effects:
[0015] 1. This utility model proposes an easy-to-install cable protection sleeve, which is provided with a first connecting block and a second connecting block. During use, its main function is to connect two main sleeves. The first connecting block slides along the sliding groove under the action of the slider, so that the first connecting block and the main sleeve move relative to each other. The first connecting block is simultaneously fitted on the outer surface of the two main sleeves, and the second connecting block is locked by the cooperation of the limiting block and the limiting groove, so as to realize the connection of the two main sleeves. This can replace bolts for fixed connection, realize the installation of the protection sleeve quickly, and avoid the disassembly difficulties caused by bolt corrosion.
[0016] 2. This utility model proposes an easy-to-install cable protection sleeve. The sleeve is equipped with arc-shaped clamps. During use, when the two arc-shaped clamps approach the cable body from both sides, the spring telescopic rod retracts under the obstruction of the cable body, and the arc-shaped clamps move to both sides. The elastic force in the spring telescopic rod can clamp the cable body with the arc-shaped clamps. At the same time, the waterproof plug enhances the clamping force and stability of the arc-shaped clamps, and the elastic pad protects the cable. This achieves stable clamping of the cable and ensures the protective sleeve's protective function for the cable. Attached Figure Description

[0023] 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.
[0024] Reference Figure 1-4An embodiment of this utility model provides: a cable protection sleeve that is easy to install, including a cable body 1, two main body sleeves 2, two No. 1 connecting blocks 5 and four waterproof plugs 13. The outer surfaces of the two main body sleeves 2 are provided with sliding grooves 3 near the upper and lower ends. The upper and lower ends of the two main body sleeves 2 are slidably fitted with limiting blocks 4. The inner surfaces of the two No. 1 connecting blocks 5 are fixedly provided with sliders 6 near the upper and lower ends. The upper and lower ends of the two No. 1 connecting blocks 5 are fixedly provided with No. 2 connecting blocks 7. The opposite ends of the four No. 2 connecting blocks 7 are provided with grooves 8. The opposite ends of the four No. 2 connecting blocks 7 are provided with limiting grooves 9 near the front and rear ends. The opposite sides of the four No. 2 connecting blocks 7 are fixedly fitted with spring telescopic rods 10. The opposite ends of the four spring telescopic rods 10 are fixedly provided with arc-shaped clamps 11.
[0025] Two main body sleeves 2 are respectively fitted on both sides of the cable body 1. The cable body 1 is fitted between the four waterproof plugs 13 in pairs. The four limiting blocks 4 are connected to the two main body sleeves 2 by springs. The four limiting blocks 4 are respectively engaged in the eight limiting grooves 9. The two No. 1 connecting blocks 5 are respectively slidably fitted on the outer surface of the two main body sleeves 2. The four sliders 6 are respectively slidably set in the four sliding grooves 3.
[0026] Four waterproof plugs 13 are respectively fitted into four No. 2 connecting blocks 7. The outer surfaces of the four waterproof plugs 13 are respectively fitted into four grooves 8 near the upper end. The inner surfaces of the four waterproof plugs 13 are respectively fitted into the outer surfaces of four arc-shaped clamps 11 near the lower end. The four arc-shaped clamps 11 are respectively fitted into the outer surfaces of the cable body 1 near the upper and lower ends. Elastic pads 12 are fixedly installed on opposite sides of each pair of arc-shaped clamps 11. The four elastic pads 12 are respectively fitted into the outer surfaces of the cable body 1 near the upper and lower ends.
[0027] Specifically, the cable body 1 is the part of the cable that needs protection, and the main body sleeve 2 is the main part of the protective sleeve. The two main body sleeves 2 can be combined into a whole tubular structure. Since the cable body 1 may generate a certain amount of heat during operation, and the cable has a certain amount of thermal expansion and contraction, the protective sleeve needs to leave a certain gap. The inner diameter of the main body sleeve 2 is larger than the outer diameter of the cable body 1. The limiting block 4 is fitted on the upper and lower ends of the main body sleeve 2. The limiting block 4 and the main body sleeve 2 are connected by a spring. When the limiting block 4 is squeezed by an external force, the spring inside it contracts, and the limiting block 4 will retract into the main body sleeve 2. When the limiting block 4 is no longer squeezed by an external force, the limiting block 4 will slide outward under the elastic force of the spring.
[0028] The first connecting block 5 is an arc-shaped "I" structure with the same inner diameter as the outer diameter of the main body sleeve 2. It can slide horizontally along the outer surface of the main body sleeve 2. The inner surface of the first connecting block 5 is provided with a slider 6. When relative rotation occurs between the first connecting block 5 and the main body sleeve 2, the slider 6 slides along the slide groove 3. The connection between the first connecting block 5 and the main body sleeve 2 is achieved through the slider 6 and the slide groove 3, while ensuring the stability of relative rotation between the two.
[0029] Four No. 2 connecting blocks 7 are divided into two groups. Two of each group are fixed to the upper and lower ends of No. 1 connecting block 5 respectively. Their inner diameter is the same as that of the main body sleeve 2, and their outer diameter is the same as that of No. 1 connecting block 5. A groove 8 is opened at the end of No. 2 connecting block 7 away from No. 1 connecting block 5. The size of the groove 8 matches the size of the waterproof plug 13 and is used to place the waterproof plug 13. A limiting groove 9 is opened at the end of No. 2 connecting block 7 close to No. 1 connecting block 5. The limiting groove 9 is U-shaped. Its upper two sides can be engaged with the limiting grooves 9 on two No. 2 connecting blocks 7 at the same time. The limiting groove 9 and the limiting block 4 have two states. When No. 1 connecting block 5 does not rotate, the limiting block 4 retracts into the main body sleeve 2 under the pressure of No. 2 connecting block 7. When No. 1 connecting block 5 rotates, the limiting groove 9 faces the limiting block 4. The limiting block 4 engages with the limiting groove 9 under the action of the spring, locking the position of No. 2 connecting block 7.
[0030] Although the spring is made of a highly elastic material, it may still experience spring fatigue after long-term use. The distance that the limiting block 4 slides outward may not be enough, but this will not affect the locking effect of the second connecting block 7. In the horizontal direction, the width of the limiting block 4 remains unchanged and it is still stably engaged with the limiting groove 9 to ensure the locking of the second connecting block 7. In the vertical direction, in addition to the engagement of the limiting block 4, the second connecting block 7 and the main body sleeve 2 are also connected by the slider 6 and the sliding groove 3, which can ensure the stability in the vertical direction. Furthermore, the inner side of the limiting groove 9 is provided with a barb structure to prevent vibration from causing the limiting block 4 to loosen. Only when the limiting block 4 is manually pressed can the limiting block 4 retract into the main body sleeve 2.
[0031] The spring telescopic rod 10 is a rod-shaped device with telescopic function. It combines the characteristics of a spring and a rod. When an external force is applied to the spring telescopic rod 10, the rod can be compressed and the spring will store or release elastic potential energy accordingly. After the external force disappears, the elastic force of the spring will cause the rod to return to its original length. The inner surface of the arc-shaped clamp 11 fits closely to the outer surface of the cable body 1. The elastic pad 12 has a certain elasticity and is located between the cable body 1 and the arc-shaped clamp 11. It can effectively prevent the pressure of the arc-shaped clamp 11 from being too high and causing damage to the cable body 1.
[0032] The waterproof plug 13 consists of two parts, both made of elastic rubber. It fits snugly against the cable body 1 and the second connecting block 7, providing excellent waterproofing. One part is fitted into the groove 8, with a larger outer diameter. The other part is fitted between the arc-shaped clamp 11 and the second connecting block 7, with a tapered inner surface. By adjusting the depth of the waterproof plug 13 in the groove 8, the force applied to the arc-shaped clamp 11 is adjusted. With the cable size remaining constant, the deeper the waterproof plug 13 is inserted, the greater the pressure on the arc-shaped clamp 11. The insertion depth of the waterproof plug 13 can be adjusted according to actual needs to ensure the clamping effect of the arc-shaped clamp 11 on the cable body 1. Due to the elasticity of the waterproof plug 13, the inner surface of the plug 13, near the upper end, is in close contact with the outer surface of the cable body 1, preventing moisture from entering the sleeve and providing a certain degree of waterproofing for the cable segment located within.
[0033] Working principle: When it is necessary to install cable protection sleeve, the two main sleeves 2 are brought close to the cable body 1 from both sides. After the elastic pad 12 on the inner side of the arc-shaped clamp 11 contacts the outer surface of the cable body 1, the two main sleeves 2 are brought closer to each other until they contact each other. During this process, the arc-shaped clamp 11 is blocked by the cable body 1, and the spring telescopic rod 10 retracts, so that the two arc-shaped clamps 11 clamp the cable body 1 from both sides. At this time, the clamping effect is not very stable.
[0034] Then, holding the two main body sleeves 2 with one hand, and simultaneously sliding the two No. 1 connecting blocks 5 with the other hand, under the restriction of the slider 6 and the slide groove 3, the No. 1 connecting block 5 and the No. 2 connecting block 7 rotate along the outer surface of the main body sleeve 2. After rotating 90 degrees, the limiting groove 9 and the limiting block 4 are directly opposite each other. At this time, the limiting block 4 is not under the pressure of the No. 2 connecting block 7. Under the action of the internal spring, the limiting block 4 slides outward, so that the limiting block 4 simultaneously engages with the limiting groove 9 on the two No. 2 connecting blocks 7. On the one hand, the position of the No. 2 connecting block 7 can be locked, and the two main body sleeves 2 can be vertically limited by the two No. 2 connecting blocks 7. On the other hand, the connection of the two No. 2 connecting blocks 7 can be achieved by the limiting block 4, thereby achieving the connection of the two main body sleeves 2.
[0035] Finally, the waterproof plug 13 is placed in the groove 8, so that the lower end of the waterproof plug 13 is fitted between the arc-shaped clamp 11 and the main body sleeve 2. The waterproof plug 13 exerts a squeezing effect on the arc-shaped clamp 11 through the conical inclined surface. In this way, the waterproof plug 13 can achieve the waterproof function and improve the stability of the arc-shaped clamp 11.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
