Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools for power equipment, and in particular to a convenient fast locking device for wire harnesses. Background Technology

[0002] In power construction, communication room wiring, and daily cable management, cable bundling devices are widely used to gather and fix scattered cables to keep the lines neat and safe. Traditional cable bundling reels or clips consist of a base and a cover plate. The cable bundling function is achieved by placing the cable between the two and closing and fixing it. The connection and fixing method directly affects the operating efficiency and user experience of the construction personnel.

[0003] However, existing wire harnesses mainly use bolts or simple interference fit clips for connection and fixation. While bolts provide a secure connection, installation and disassembly require tools such as screwdrivers, and each screw must be tightened individually, making the process cumbersome and time-consuming, especially in confined spaces or at heights. Simple clip connections eliminate the need for tools, but they often lack effective guiding mechanisms during closure, leading to jamming or misalignment. More importantly, unlocking these devices usually requires operators to manually pry open the clips or pry open the cover from the side seam, which is not only laborious but also prone to finger injuries. After unlocking, the cover does not automatically separate and still needs to be manually pulled out, failing to meet the demands of modern construction for efficient and convenient operation.

[0004] Therefore, this utility model proposes a convenient fast locking device for wire harnesses to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the problems that existing wire harness devices generally have, such as cumbersome locking and fixing methods, lack of effective guidance during closure leading to easy misalignment, and laborious unlocking and inability to automatically separate, resulting in low ease of use, this utility model aims to provide a convenient quick locking device for wire harness devices with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a convenient fast locking device for cable ties, including: a cable tie coil component and a locking mechanism disposed on the cable tie coil component; the locking mechanism includes a fixing block fixedly connected to the front side of the cable tie coil component and a sliding block slidably connected to the right end of the front side of the cable tie coil component.

[0007] The sliding block has a sliding block fixedly connected to the front and rear ends on the left side. The sliding block has a housing fixedly connected to the upper and lower sides of the inner wall of the sliding block. The inner wall of the housing is equipped with an elastic lock head. The fixed block has slots on the front and rear ends on the right side. The slots are slidably connected to the sliding block. The upper and lower ends of the left side of the slot have locking grooves. The inner wall of the locking groove is locked and engaged with the end of the elastic lock head.

[0008] Furthermore, a push rod is slidably connected to the inner wall of the fixed block on all four sides. A return spring is sleeved on the outer side of the push rod. A pressing block is fixedly connected to the top of the upper push rod and a pressing block is fixedly connected to the bottom of the lower push rod. The end of the push rod away from the pressing block extends to the locking groove and abuts against the end of the elastic lock head. When the pressing block is moved by force, it drives the push rod to push the elastic lock head back into the inner wall of the outer shell to release the locking state between the fixed block and the sliding block.

[0009] Preferably, both the fixing block and the sliding block have arc-shaped grooves on their inner sides, and when the fixing block and the sliding block are in contact with each other, the arc-shaped grooves form a circular groove; both the fixing block and the sliding block have multiple clamping pads fixedly connected at equal intervals on their inner sides, and the inner side of the clamping pads is used to fit tightly against the outer side of the cable to increase the friction on the cable and prevent hard damage.

[0010] Preferably, the convenient cable tie quick locking device further includes a guide sliding mechanism, which includes guide sliding rods fixedly connected to the four corners on the right side of the fixed block, and an ejector spring 1 slidably connected to the outer wall of the guide sliding rods; the left end of the ejector spring 1 is fixedly connected to the right side of the fixed block, and the right end of the ejector spring 1 abuts against the left side of the sliding block, and the ejector spring 1 provides a reverse thrust at the moment of unlocking.

[0011] Preferably, a limiting slider is fixedly connected to the right end of the outer wall of the guide rod, and a limiting guide groove is opened at each of the four corners of the sliding block. The inner wall of the limiting guide groove is slidably connected to the guide rod and the limiting slider, thereby ensuring the stability and straightness of the sliding block during movement.

[0012] Preferably, when the fixed block and the sliding block are unlocked, the ejector spring releases its elastic force to push the sliding block to slide to the right along the guide rod. The left side of the limiting slider and the middle of the inner wall of the limiting guide groove are in contact with each other to limit the displacement distance of the sliding block and prevent the sliding block from displacing excessively under the action of the elastic force.

[0013] Preferably, there are two pressing blocks, located at the top and bottom of the fixed block respectively; the pressing block at the top is connected to the two upper push rods, and the pressing block at the bottom is connected to the two lower push rods, realizing the simultaneous unlocking linkage of multiple push rods through a single-point pressing operation.

[0014] Preferably, one end of the return spring abuts against the protrusion on the outer wall of the push rod, and the other end abuts against the inner wall of the fixing block; when the external force on the pressing block is removed, the return spring uses its own elasticity to push the push rod to reset, ensuring that the unlocking mechanism can automatically return to the initial state for the next locking.

[0015] Preferably, the depth of the slot is greater than the length of the sliding block, and the slot is connected to the locking groove; the resilient lock head includes a spring and a latch, the spring being used to push the latch outward so that the latch engages with the locking groove, thereby creating a stable automatic latching connection.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem of cumbersome, time-consuming and labor-intensive operation caused by the use of bolt fastening or simple binding in existing cable bundling devices by setting an automatic buckle locking structure consisting of a sliding block, a slot and an elastic lock head between the fixed block and the sliding block, and cooperating with a linkage unlocking structure consisting of a pressing block, a top rod and a return spring. It achieves the effect of automatic locking with just a push and quick unlocking with just a press, which greatly improves the efficiency of cable bundling work.

[0018] 2. This utility model solves the problems of existing quick locking devices, such as the lack of precise guidance during the movement of the locking components, leading to positioning difficulties, and the inability to automatically reset after unlocking, requiring manual separation, by setting a guide mechanism including a guide rod, an ejector spring, and a limiting slider between the fixed block and the sliding block. It achieves the effect of smooth and stable movement of the sliding block, automatic ejection and separation by spring force at the moment of unlocking, and prevention of falling off by the limiting slider, thereby improving the stability and reliability of the device operation.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example:

[0029] Please refer to Figures 1 to 6 This utility model provides a convenient fast locking device for wire harnesses, which aims to solve the structural defects of existing wire harnesses, such as cumbersome locking operations and lack of precise guiding and resetting mechanisms.

[0030] Please refer to Figure 1 and Figure 2 The convenient cable harness quick-locking device includes a cable harness reel component 1 and a locking mechanism 2 disposed on the cable harness reel component 1. The cable harness reel component 1 is used to carry cables and serve as an installation base. The locking mechanism 2 is used to realize the quick fixing and releasing operation of the cables. The locking mechanism 2 includes a fixing block 21 fixedly connected to the front side of the cable harness reel component 1 and a sliding block 22 slidably connected to the right end of the front side of the cable harness reel component 1. The fixing block 21 remains fixed in position, and the sliding block 22 can move along the surface of the cable harness reel component 1 relative to the cable harness reel component 1. The fixed block 21 performs linear reciprocating motion. Both the fixed block 21 and the sliding block 22 have arc-shaped grooves on their inner sides. When the fixed block 21 and the sliding block 22 are in contact with each other, the two arc-shaped grooves meet to form a circular groove to adapt to the cross-sectional shape of the cable. Multiple clamping pads 211 are fixedly connected at equal intervals on the inner groove surfaces of the fixed block 21 and the sliding block 22. The inner surface of the clamping pad 211 is designed as an arc surface for close contact with the outer side of the cable. The clamping pad 211 increases the friction between the cable and the clamping pad and prevents damage to the cable caused by hard squeezing.

[0031] The sliding block 22 has a sliding block 23 fixedly connected to the front and rear ends on the left side. The fixed block 21 has slots 26 on the front and rear ends on the right side. The inner contour size of the slot 26 is adapted to the outer contour size of the sliding block 23. A sliding connection is established between the slot 26 and the sliding block 23. The sliding block 22 and the fixed block 21 are restricted in the direction perpendicular to the sliding direction by the fitting method of the sliding block 23 inserting into the slot 26, thereby ensuring the stability and alignment accuracy of the sliding block 22 when it moves towards the fixed block 21 to close.

[0032] Please refer to Figure 1 and Figure 3 The locking mechanism 2 also includes an automatic insertion locking component and a linkage unlocking component disposed between the fixed block 21 and the sliding block 22. In the technical solution, the components form a tight cooperation relationship to achieve the function. The upper and lower sides of the inner wall of the insertion block 23 are fixedly connected to the outer shell 24. The outer shell 24 has a hollow structure and contains an elastic lock head 25. The inner wall of the outer shell 24 is equipped with an elastic lock head 25. The elastic lock head 25 includes a spring and a locking tongue component that is pushed outward by the spring force. The upper and lower ends of the left side of the inner wall of the slot 26 are provided with locking grooves 27. The shape of the locking groove 27 matches the end shape of the locking tongue component in the elastic lock head 25. When the insertion block 23 is fully inserted into the slot 26, the inner wall of the locking groove 27 and the end of the elastic lock head 25 form a locking engagement relationship. The rigid connection between the fixed block 21 and the sliding block 22 is achieved by the action of the elastic lock head 25 being pressed back and then popping out.

[0033] The inner wall of the fixing block 21 has through holes around its perimeter for sliding rod-shaped components, and four push rods 28 are slidably connected to them. Each push rod 28 has four corners located inside the fixing block 21. A return spring 29 is fitted onto the outer side of each push rod 28. One end of the return spring 29 abuts against a protrusion on the outer wall of the push rod 28, and the other end abuts against the inner wall of the fixing block 21. The end of the push rod 28 away from the return spring 29 extends to the locking groove 27 and abuts against the end of the elastic lock head 25. The top ends of the two upper push rods 28 extend out of the fixing block 21 and are fixedly connected. There is a single pressing block 210. The bottom ends of the two push rods 28 on the lower side extend out of the fixing blocks 21 and are fixedly connected to the same pressing block 210. When the pressing block 210 is pressed by an external force, it drives the corresponding push rod 28 to slide inward along the inner wall of the fixing block 21. During the sliding process, the push rod 28 pushes the elastic lock head 25 back into the inner wall of the outer shell 24, thereby causing the elastic lock head 25 to disengage from the locking groove 27 to release the locking state between the fixing block 21 and the sliding block 22. After the external force of the pressing block 210 is removed, the return spring 29 uses its own elasticity to push the push rod 28 to return to its original position.

[0034] As a preferred embodiment, in order to achieve more precise guidance of the sliding block 22 relative to the fixed block 21 during sliding, and to achieve the automatic pop-out limit function after unlocking, please refer to... Figure 4 , Figure 5 and Figure 6 The convenient wire harness quick-locking device also includes a guide sliding mechanism 3, which is located between the fixed block 21 and the sliding block 22. Guide sliding rods 31 are fixedly connected to the four corners on the right side of the fixed block 21. Each guide sliding rod 31 is a smooth rod-shaped structure of a certain length. A push-out spring 32 is slidably connected to the outer wall of the guide sliding rod 31. The push-out spring 32 is a helical compression spring. The left end of the push-out spring 32 is fixedly connected to the right side surface of the fixed block 21, and the right end of the push-out spring 32 extends towards the sliding block 22 in its natural state and abuts against the left side surface of the sliding block 22. Limiting sliders 33 are fixedly connected around the four corners of the outer right end of the guide sliding rod 31. The limiting sliders 33 act as physical blocking components to prevent detachment. The four corners of the sliding block 22 are... Limiting guide grooves 34 are provided at the positions of the guide rods 31. The limiting guide grooves 34 are through grooves or blind grooves. The inner walls of the limiting guide grooves 34 are slidably connected to the guide rods 31 and the limiting sliders 33 respectively. The guide rods 31 are inserted into the limiting guide grooves 34 to limit the movement trajectory of the sliding block 22. When the fixed block 21 and the sliding block 22 are unlocked, the ejector spring 32, which is in a compressed state, releases its elastic force to push the sliding block 22 to slide to the right along the guide rods 31. The left side of the limiting slider 33 is in contact with the stepped surface provided in the middle of the inner wall of the limiting guide groove 34. The contact between the limiting slider 33 and the inner wall of the limiting guide groove 34 limits the maximum displacement distance of the sliding block 22 when it is pushed by the ejector spring 32, preventing the sliding block 22 from detaching from the guide rods 31.

[0035] As another preferred embodiment, in order to enhance the clamping stability of the cable and reduce damage to the cable surface, both the fixing block 21 and the sliding block 22 have arc-shaped grooves on their inner sides. When the fixing block 21 and the sliding block 22 are in contact with each other, the arc-shaped grooves on the fixing block 21 and the sliding block 22 together form a circular groove. Multiple clamping pads 211 are fixedly connected at equal intervals on the inner groove surfaces of the fixing block 21 and the sliding block 22. The clamping pads 211 are made of materials with a certain elasticity and high coefficient of friction, such as rubber or soft plastic. The inner side of the clamping pads 211 is arc-shaped to fit tightly against the outer side of the cable.

[0036] As another preferred embodiment, in order to facilitate the operator to apply force to unlock, there are two pressing blocks 210, located at the top and bottom of the fixing block 21 respectively. The pressing block 210 at the top is connected to the two upper push rods 28, and the pressing block 210 at the bottom is connected to the two lower push rods 28. The pressing block 210 converts the single-point force into a synchronous driving force on the push rods 28 on both sides.

[0037] As another preferred embodiment, in order to ensure the reliability of the locking structure, the depth of the slot 26 is greater than the length of the sliding block 23, and the internal space of the slot 26 is connected to the locking groove 27. The elastic lock head 25 includes a spring and a locking tongue. The spring is set inside the housing 24 to push the locking tongue outward so that the locking tongue is engaged in the locking groove 27. The inner wall of the locking groove 27 is provided with a slot structure that cooperates with the end of the locking tongue.

[0038] Working principle:

[0039] When using the convenient cable bundling device for quick locking, the cable end is inserted into the groove inside the fixing block 21. The operator slides the sliding block 22 along the inner wall of the cable bundling component 1 to the left. The sliding block 22 drives the front and rear side insertion sliders 23 to insert into the corresponding slots 26. During this process, the guide rod 31 and the limit slider 33 slide on the inner wall of the upper limit guide groove 34 of the sliding block 22 to guide. At the same time, the sliding block 22 squeezes the ejector spring 32, causing the ejector spring 32 to be compressed and stored. When the insertion slider 23 is inserted into place, the end of the elastic lock head 25 installed on the inner wall of the outer shell 24 is locked into the corresponding locking groove 27 under its own elastic force, completing the automatic locking between the fixing block 21 and the sliding block 22. At this time, the circular groove formed by the inner sides of the fixing block 21 and the sliding block 22, together with multiple clamping pads 211, completes the quick clamping and locking of the cable.

[0040] When the cable bundle component 1 has finished bundling the cable and needs to be removed, press the upper and lower pressing blocks 210 on both sides of the fixing block 21. The two pressing blocks 210 push the corresponding push rods 28 to slide inward along the inner wall of the fixing block 21. During the sliding process, the push rods 28 squeeze the reset spring 29 and push the end in the corresponding elastic lock head 25, so that the elastic lock head 25 is forced to retract into the inner wall of the corresponding outer shell 24. The end of the elastic lock head 25 disengages from the inner wall of the corresponding locking groove 27, thereby releasing the lock between the fixing block 21 and the sliding block 22. After the lock is released, the ejector spring 32, which is in a compressed state, releases its elastic force and pushes the sliding block 22 to the right along the outer wall of the guide rod 31. The left side of the limiting slider 33 is attached to the middle of the inner wall of the corresponding limiting guide groove 34 to limit the displacement of the sliding block 22 and prevent it from falling off. At this time, the bundled cable can be removed from the outside of the cable bundle component 1.
