Description

Technical Field

[0001] This utility model relates to the field of elastic spiral wire harnesses, and in particular to an elastic spiral wire harness. Background Technology

[0002] A wire harness is a structure consisting of a group of wires or cables that are typically bundled or wrapped together to provide convenience and protection when transmitting power or signals.

[0003] When using a spiral wire harness body for circuit connection, the connecting ends at both ends of the spiral wire harness body need to be inserted into the slots on the two devices respectively. During daily use, the surface of the spiral wire harness body is stretched and bent, which will cause tension on the connecting ends and cause the connection between the spiral wire harness body and the connecting ends to deflect too much. This will loosen the connection between the spiral wire harness body and the connecting ends, causing the spiral wire harness body to break or fall off from the connecting ends, affecting the normal use of the spiral wire harness body. Utility Model Content

[0004] The technical problem this utility model aims to solve is that when using a spiral wire harness body for circuit connection, the connecting ends at both ends of the spiral wire harness body need to be inserted into slots on two devices respectively. During daily use, the surface of the spiral wire harness body is stretched and bent, which will cause tension on the connecting ends and cause the connection between the spiral wire harness body and the connecting ends to deflect at an excessive angle, making the connection between the spiral wire harness body and the connecting ends loose, resulting in the spiral wire harness body breaking or falling off from the connecting ends, thus affecting the normal use of the spiral wire harness body.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an elastic spiral wire harness, including a spiral wire harness body, both ends of which are provided with connecting ends, and a limiting device is provided between both ends of the spiral wire harness body and the two connecting ends. The limiting device can provide secondary fixed support for both ends of the spiral wire harness body and both sides of the two connecting ends, so that the connection between the two is not prone to breakage, damage or detachment during use, thereby improving the stability and service life of the spiral wire harness body.

[0006] The effect achieved by the above-mentioned components is that when using the spiral wire harness body for circuit connection, the two ends of the spiral wire harness body can be fixed to the two connecting ends by means of the limiting device. This makes it less likely to break, be damaged or fall off when the connecting ends of the spiral wire harness body are inserted into the slots of the two devices during use, thus improving the stability and service life of the spiral wire harness body.

[0007] Preferably, the limiting device includes two limiting rods, one end of each limiting rod is rotatably connected to the outer surface of one end of the spiral wire harness body, a groove is provided on one side of the limiting rod, a connecting spring is fixedly connected to one side of the inner wall of the groove, a locking block is fixedly connected to one end of the connecting spring, the locking block is slidably connected to the groove, and locking holes are fixedly connected to both sides of the connecting end, with one end of the limiting rod and the locking block respectively inserted into the inner wall of the locking hole block.

[0008] The effect achieved by the above-mentioned components is as follows: By setting a limiting device, before using the spiral wire harness body, the limiting rod can be manually rotated to a certain angle on the outer surface of one end of the spiral wire harness body, so that the locking block on one end abuts against the locking hole block, squeezing it and causing it to retract into the inner wall of the slide groove. This causes the connecting spring to retract. When one end of the limiting rod is inserted into the inner wall of the locking hole block to a certain position, under the reset action of the connecting spring, one end of the locking block can be driven into the inner wall of the locking hole block, limiting the limiting rod and making a secondary fixed connection between one end of the spiral wire harness body and the connecting end. This makes it less likely to break, be damaged or fall off when the connecting ends of both ends of the spiral wire harness body are inserted into the slots of two devices during use and subjected to excessive tension, thus improving the stability and service life of the spiral wire harness body.

[0009] Preferably, a telescopic rod is fixedly connected to one side of the inner wall of the slide, one end of the telescopic rod is fixedly connected to one side of the locking block, and the outer surface of the telescopic rod is sleeved and connected to the inner wall of the connecting spring.

[0010] The effect achieved by the above components is that by setting up the telescopic rod, the inner wall of the connecting spring can be supported and reinforced, making it less prone to damage during use and increasing its service life.

[0011] Preferably, an auxiliary mechanism is provided between one side of the two limiting rods. The auxiliary mechanism includes a connecting rod, the two ends of which are fixedly connected to one side of the two limiting rods respectively. Reinforcing rods are fixedly connected to both sides of the connecting rod, and one side of the reinforcing rod is fixedly connected to one side of the limiting rod.

[0012] The effect achieved by the above components is that, by setting up an auxiliary mechanism, the two limit rods can be connected and fixed together by a connecting rod and a reinforcing rod. When limiting, the two limit rods can be operated at the same time, which facilitates installation.

[0013] Preferably, one end of the locking block has a trapezoidal cross-section, and the trapezoidal end of the locking block is located at the end away from the connecting spring.

[0014] The effect achieved by the above-mentioned components is that by setting one end of the locking block in a trapezoidal shape, when the limiting rod rotates to a certain angle, it can cause one side of the locking block to abut against the locking hole block, which facilitates the compression of the block in the groove and makes subsequent installation easier.

[0015] Preferably, the support device includes a spring frame, which is disposed inside the spiral wire harness body. Several elastic arc blocks are fixedly connected to both ends of the outer surface of the spring frame, and the outer surface of the spiral wire harness body is inserted into the inner wall of the elastic arc blocks.

[0016] The effect achieved by the above components is as follows: by setting up a support device, the interior of the spiral wire harness body can be supported and reinforced by the spring frame and several elastic arc blocks, which can improve the elasticity of the spiral wire harness body, while making it less susceptible to being pulled and damaged, and increasing its service life.

[0017] Preferably, the inner wall of the elastic arc block is fixedly connected with an anti-slip block, which is made of rubber.

[0018] The effect achieved by the above components is that by setting anti-slip blocks, the contact friction of the inner wall of the elastic arc block can be increased, so that the main body of the spiral wire harness can be more firmly and stably stuck into the inner wall of the elastic arc block, and it is not easy to slip.

[0019] Preferably, the outer surface of the elastic arc block is symmetrically fixedly connected with limiting blocks, and the two limiting blocks are fixed at an angle on both sides of the entrance of the elastic arc block.

[0020] The effect achieved by the above components is that by setting the limiting block, the area at the entrance of the elastic arc block can be increased, which facilitates the alignment and installation of the spiral wire harness body.

[0021] The beneficial effects of this utility model are:

[0022] By setting a limiting device, the two ends of the spiral wire harness body and the two connecting ends can be fixed and supported twice. This makes it less likely to break, be damaged or fall off when the connecting ends of the spiral wire harness body are inserted into the slots on the two devices during use, and improves the stability and service life of the spiral wire harness body.

Detailed Implementation

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Figure 1-5 The diagram illustrates an elastic spiral wire harness, comprising a spiral wire harness body 1. Both ends of the spiral wire harness body 1 are provided with connecting ends 4. Limiting devices 2 are provided between both ends of the spiral wire harness body 1 and the two connecting ends 4. The limiting devices 2 provide secondary fixation and support to both ends of the spiral wire harness body 1 and both sides of the two connecting ends 4, preventing breakage, damage, or detachment at the connection points during use, thus improving the stability and service life of the spiral wire harness body 1. When using the spiral wire harness body 1 for circuit connections, the limiting devices 2 can be used to secondary fix both ends of the spiral wire harness body 1 to the two connecting ends 4, preventing breakage, damage, or detachment under excessive tensile force during use when the connecting ends 4 at both ends of the spiral wire harness body 1 are inserted into slots on two devices, further improving the stability and service life of the spiral wire harness body 1.

[0033] Figure 2-4The limiting device 2 shown includes two limiting rods 21. One end of each limiting rod 21 is rotatably connected to the outer surface of one end of the spiral wire harness body 1. A groove 22 is provided on one side of the limiting rod 21. A connecting spring 23 is fixedly connected to one side of the inner wall of the groove 22. A locking block 24 is fixedly connected to one end of the connecting spring 23. The locking block 24 is slidably connected to the groove 22. Locking holes 25 are fixedly connected to both sides of the connecting end 4. One end of the limiting rod 21 and the locking block 24 are respectively inserted into the inner wall of the locking hole 25. Before using the spiral wire harness body 1, the limiting rod 21 can be manually rotated to a certain angle on the outer surface of one end of the spiral wire harness body 1, so that one side of the locking block 24 on one end abuts against one side of the locking hole block 25, squeezing it to retract into the inner wall of the slide groove 22, causing the connecting spring 23 to retract. When one end of the limiting rod 21 is inserted into the inner wall of the locking hole block 25 to a certain position, under the reset action of the connecting spring 23, one end of the locking block 24 can be inserted into the inner wall of the locking hole block 25, limiting the limiting rod 21 and making a secondary fixed connection between one end of the spiral wire harness body 1 and the connecting end 4. This makes it less likely to break or fall off when the connecting ends 4 at both ends of the spiral wire harness body 1 are inserted into the slots of two devices during use, and improves the stability and service life of the spiral wire harness body 1. A telescopic rod 27 is fixedly connected to one side of the inner wall of the slide 22. One end of the telescopic rod 27 is fixedly connected to one side of the locking block 24, and the outer surface of the telescopic rod 27 is sleeved and connected to the inner wall of the connecting spring 23. By setting the telescopic rod 27, the inner wall of the connecting spring 23 can be supported and reinforced, making it less prone to damage during use and improving its service life.

[0034] Figure 2-4 An auxiliary mechanism 26 is provided between one side of the two limiting rods 21 shown. The auxiliary mechanism 26 includes a connecting rod 261, with both ends of the connecting rod 261 fixedly connected to one side of each of the two limiting rods 21. Reinforcing rods 262 are fixedly connected to both sides of the connecting rod 261, with one side of each reinforcing rod 262 fixedly connected to one side of a limiting rod 21. By providing the auxiliary mechanism 26, the two limiting rods 21 can be connected and fixed together via the connecting rod 261 and the reinforcing rod 262. During limiting, both limiting rods 21 can be operated simultaneously, facilitating installation.

[0035] Figure 2-4 The trapezoidal cross-section of one end of the shown locking block 24 is located at the end away from the connecting spring 23. By setting one end of the locking block 24 into a trapezoidal shape, when the limiting rod 21 rotates to a certain angle, it can cause one side of the locking block 24 to abut against the locking hole block 25, making it easier to squeeze it and cause it to shrink in the slide groove 22, which facilitates subsequent installation.

[0036] Figure 5 The support device 3 shown includes a spring frame 31, which is disposed inside the spiral wire harness body 1. Several elastic arc blocks 32 are fixedly connected to both ends of the outer surface of the spring frame 31. The outer surface of the spiral wire harness body 1 is inserted into the inner wall of the elastic arc blocks 32. The spring frame 31 and the elastic arc blocks 32 can support and reinforce the interior of the spiral wire harness body 1, improving its elasticity and making it less prone to tearing, thus extending its service life. Anti-slip blocks 33, made of rubber, are fixedly connected to the inner wall of the elastic arc blocks 32. By setting the anti-slip blocks 33, the contact friction of the inner wall of the elastic arc blocks 32 is increased, making the spiral wire harness body 1 more firmly and stably inserted into the inner wall of the elastic arc blocks 32, preventing slippage. Limiting blocks 34 are symmetrically fixedly connected to the outer surface of the elastic arc blocks 32, with two limiting blocks 34 fixed at an angle on both sides of the entrance of the elastic arc blocks 32. By setting the limiting block 34, the area at the entrance of the elastic arc block 32 can be increased, making it easier to align and install the spiral wire harness body 1.

[0037] Working principle: Before using the spiral wire harness body 1, the connecting rod 261 can be manually held to rotate the two limiting rods 21 on the outer surface of one end of the spiral wire harness body 1 to a certain angle, so that one side of the locking block 24 on one end abuts against one side of the locking hole block 25, squeezing it to retract into the inner wall of the slide groove 22, causing the connecting spring 23 and the telescopic rod 27 to retract. When one end of the limiting rod 21 is inserted into the inner wall of the locking hole block 25 to a certain position, under the reset action of the connecting spring 23 and the telescopic rod 27, one end of the locking block 24 can be driven into the inner wall of the locking hole block 25, limiting the limiting rod 21, and making a secondary fixed connection between one end of the spiral wire harness body 1 and the connecting end 4. This makes it less likely to break or fall off when the connecting ends 4 at both ends of the spiral wire harness body 1 are inserted into the slots of two devices during use, when subjected to excessive tension, thus improving the stability and service life of the spiral wire harness body 1.

[0038] By setting up the support device 3, the interior of the spiral wire harness body 1 can be supported and reinforced by the spring frame 31 and several elastic arc blocks 32, which can improve the elasticity of the spiral wire harness body 1 and make it less susceptible to being pulled and damaged, thus increasing its service life.
