Description

Technical Field

[0001] This utility model relates to the field of cable tie technology, and in particular to a reusable cable tie. Background Technology

[0002] Cable ties, also known as wire ties, cable management straps, or locking straps, are straps used to bundle things together. They are generally classified by material, such as nylon cable ties, stainless steel cable ties, and powder-coated stainless steel cable ties. By function, they are classified into ordinary cable ties, retractable cable ties, label cable ties, fixed locking cable ties, pin-type cable ties, heavy-duty cable ties, and so on.

[0003] Typically, cable ties have toothed grooves and built-in elastic barbs in the buckle. Once inserted, they lock in one direction and require external force to unlock. However, long-term and repeated use of only the barbs for fastening can easily cause wear or deformation to the end face and cone angle of the barbs, thereby reducing the overall locking force of the cable tie. In severe cases, the cable tie may even come loose. Furthermore, traditional cable ties only have a tightening effect. When used for binding pipe ends, there is a risk that the cable tie may shrink under force due to external contact, causing compression and deformation of the elastic pipe end face. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the problems existing in the above and / or existing reusable cable ties, this utility model is proposed.

[0006] Therefore, the problem that this utility model aims to solve is that the existing locking structure of the strap is prone to wear after repeated use and the shrinkage range cannot be kept constant.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a reusable cable tie, comprising a main body component including a housing, wherein a strap with an end inserted into the housing is provided on one side;

[0008] A locking assembly is disposed inside the housing. The locking assembly includes a wheel disposed inside the housing. The surface of the wheel is arranged in a circular array with multiple locking blocks facing the same direction as the teeth on the surface of the strap. An axle is inserted into the inside of the wheel, and locking sleeves are provided at both ends of the axle.

[0009] As a preferred embodiment of the reusable cable tie of this utility model, the locking assembly further includes openings on both sides of the housing, the openings being coaxial with the shaft, and the locking sleeve being movably connected to the end of the shaft via a bearing ring.

[0010] As a preferred embodiment of the reusable cable tie of this utility model, the locking assembly further includes an abutment block disposed below the wheel, the upper part of the abutment block contacting the teeth on the surface of the wheel, and a buffer fixed to the inner wall of the housing is disposed below the abutment block.

[0011] As a preferred embodiment of the reusable cable tie of this utility model, the locking assembly further includes an arc-shaped groove on one side of the housing. The arc-shaped groove has an L-shaped design when viewed from above. One end of the arc-shaped groove is designed to penetrate the housing. A locking plate is provided in the arc-shaped groove, and the lower end of the locking plate is fixedly connected to the locking sleeve.

[0012] As a preferred embodiment of the reusable cable tie of this utility model, the locking assembly further includes a movable groove formed on the surface of the housing and located below the arc-shaped groove. A telescopic rod is slidably connected in the movable groove, and a vertical rod is fixedly connected to the other end of the telescopic rod. The end of the vertical rod near the locking sleeve is fixedly connected to the locking sleeve.

[0013] As a preferred embodiment of the reusable cable tie of this utility model, the locking assembly further includes a movable shell disposed on the surface of the housing and located below the locking sleeve. A top rod is vertically slidably connected inside the movable shell. Both sides of the surface of the top rod are fixedly connected to pressure plates. The pressure plates are rectangular in design, and the inclined surfaces of the two pressure plates are arranged in opposite directions. The inclined surface of one of the pressure plates contacts one of the telescopic rods.

[0014] As a preferred embodiment of the reusable cable tie of this utility model, the locking assembly further includes a toothed groove formed at one end of the shaft near the arc-shaped groove, and the surface of the shaft is provided with an arc-shaped shell fixed to the upper end of the top rod. The inner wall of the arc-shaped shell is toothed, and the teeth are adapted to the toothed groove.

[0015] As a preferred embodiment of the reusable cable tie of this utility model, the locking slot is provided on the side of the card block near the abutment block, and the locking slot is adapted to the upper end of the abutment block.

[0016] As a preferred embodiment of the reusable cable tie of this utility model, the surface of the locking sleeve is provided with a resistance ring, the resistance ring is made of rubber, and the surface of the resistance ring is in contact with the inner wall of the opening.

[0017] As a preferred embodiment of the reusable cable tie of this utility model, a limiting ring is fixedly connected to the inner wall of the opening, and the limiting ring is used to limit the lateral displacement distance of the locking sleeve.

[0018] The beneficial effects of this utility model are as follows: when the cable tie is inserted into the housing to bind the object, the rolling of the wheel can cause the locking blocks on the surface of the wheel to rotate accordingly. Thus, different locking blocks can be used to complete the locking operation each time it is used repeatedly, reducing the wear caused to a certain locking structure. This can effectively reduce the wear of the locking structure inside the cable tie, improve the overall service life and locking effect of the cable tie.

[0019] When cable ties are used to bind different types of objects, the curved shell can limit the insertion depth of the cable tie, thereby keeping the overall binding force of the cable tie constant. This reduces the possibility of accidental tightening of the cable tie due to external contact, which could cause pressure on the binding part of the object. It also effectively improves the overall applicability of the cable tie. Attached Figure Description

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0033] Example 1

[0034] Reference Figure 1 , Figure 2 Figure 3 and Figure 4 This is the first embodiment of the present invention, which provides a reusable cable tie, the reusable cable tie including...

[0035] The main component includes a housing 1, and a strap 2 with its end inserted into the housing 1 is provided on one side.

[0036] When it is necessary to tie up an object, first select the appropriate type of cable tie according to the size and weight of the object to be tied. Then, wrap the cable tie 2 around the object to be fixed, ensuring that the cable tie 2 completely wraps the target object. Then, reinsert the end of the cable tie 2 that has wrapped around the object into the housing 1 until the end of the cable tie 2 extends outward from the other side of the housing 1. Pull the end of the cable tie 2, and the teeth on the surface of the cable tie 2 can be used to engage with the locking structure inside the cable tie buckle to tighten the cable tie.

[0037] Locking component 3 is located inside housing 1. Locking component 3 includes a wheel 32 located inside housing 1. The surface of wheel 32 is arranged in a ring array with multiple locking blocks facing the same direction as the teeth on the surface of strap 2. An axle is inserted into the inside of wheel 32, and locking sleeves 31 are provided at both ends of the axle.

[0038] The locking assembly 3 also includes an abutment block 34 disposed below the wheel 32. The upper part of the abutment block 34 contacts the teeth on the surface of the wheel 32, and a buffer pad 33 fixed to the inner wall of the housing 1 is disposed below the abutment block 34.

[0039] Specifically, a locking groove is provided on the side of the card block near the abutment block 34, and the locking groove is adapted to the upper end of the abutment block 34;

[0040] When the strap 2 is inserted into the housing 1, the teeth on the surface of the strap 2 will first contact the locking block on the surface of the wheel 32. At this time, the wheel 32 will be turned and rotated. When the strap 2 is tightened, the wheel 32 will no longer contact the pulled strap 2. At this time, the locking block above the wheel 32 will correspond to the teeth of the strap 2 in the housing 1. Then, the locking block on the surface of the wheel 32, together with the locking groove and the abutment block 34, can lock the wheel 32 to prevent the wheel 32 from reversing and causing the strap 2 to loosen.

[0041] It should be noted that when the strap 2 is inserted into the housing 1, the wheel 32 will first be turned by the strap 2 and rotate counterclockwise. At this time, the locking block on the surface of the wheel 32 will contact the inclined surface of the turning block. Each time the locking block contacts the inclined surface of the turning block, the turning block will be pressed downward. The buffer pad 33 below the turning block will compensate for this. When the strap 2 is inserted to a certain depth, if the cable tie is used to bind the wire harness, the cable tie will be pushed outward by the strap 2. At this time, the strap 2 will move in the opposite direction. At this time, the end face of the locking block on the surface of the wheel 32 will contact the teeth, and the wheel 32 will rotate clockwise. At this time, the locking block near the abutment block 34 will contact the upper end of the abutment block 34. The locking groove of the locking block engages with the upper end of the abutment block 34, thus completing the locking operation of the wheel 32.

[0042] Example 2

[0043] Reference Figure 2 , Figure 3 , Figure 6 and Figure 7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0044] Specifically, the locking assembly 3 also includes openings on both sides of the housing 1, with the openings and the shaft on the same axis, and the locking sleeve 31 is movably connected to the end of the shaft through a bearing ring;

[0045] Specifically, the locking component 3 also includes an arc-shaped groove 35 opened on one side of the housing 1. The arc-shaped groove 35 has an L-shaped design when viewed from above. One end of the arc-shaped groove 35 is designed to penetrate the housing 1. A locking plate 39 is provided in the arc-shaped groove 35. The lower end of the locking plate 39 is fixedly connected to the locking sleeve 31.

[0046] When the person inserts the strap 2 into the housing 1, the locking sleeve 31 is connected to the shaft through a bearing. Therefore, the person can turn the locking sleeve 31 so that the locking plate 39 on the surface of the locking sleeve 31 can rotate 90 degrees clockwise along the arc groove 35. At this time, the locking sleeve 31 at this end will be locked, which can prevent the shaft from accidentally touching the strap and causing the wheel 32 to slide laterally from under the strap 2 when the strap is in use.

[0047] It should be noted that when the strap 2 is inserted into the housing 1 through the insertion hole of the housing 1, the wheel 32 is in the initial state, and the two wheels 32 and the two sets of teeth below the strap 2 are on the same axis.

[0048] When personnel need to loosen the strap 2, they only need to turn the locking sleeve 31 in the opposite direction by 90 degrees and squeeze the locking sleeve 31 laterally. At this time, the resistance ring on the surface of the locking sleeve 31 will enter the opening of the housing 1, and the wheel 32 will also be misaligned with the teeth below the strap 2. Then personnel can pull the strap 2 in the opposite direction to complete the loosening of the strap.

[0049] Specifically, the surface of the locking sleeve 31 is provided with a resistance ring, which is made of rubber, and the surface of the resistance ring is in contact with the inner wall of the opening.

[0050] By setting a resistance ring made of rubber, when the locking sleeve 31 is inserted laterally into the housing 1, the surface of the resistance ring contacts the inner wall of the opening and generates friction, thereby achieving the effect of locking the position of the shaft and wheel 32.

[0051] Specifically, a limit ring is fixedly connected to the inner wall of the opening, and the limit ring is used to limit the lateral displacement distance of the locking sleeve 31.

[0052] Example 3

[0053] Reference Figure 8 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0054] Specifically, the locking assembly 3 also includes a movable groove 36 formed on the surface of the housing 1 and located below the arc groove 35. A telescopic rod is slidably connected in the movable groove 36, and a vertical rod 37 is fixedly connected to the other end of the telescopic rod. The end of the vertical rod 37 near the locking sleeve 31 is fixedly connected to the locking sleeve 31.

[0055] When the strap 2 is inserted into the housing 1, the operator will turn the locking sleeve 31 to lock the position of the wheel 32 in the manner described above. When the locking sleeve 31 rotates clockwise, the vertical rod 37 on the right will move from below the arc groove 35 along the movable groove 36 to the bottom and contact one of the pressure plates. The inclined angle of this pressure plate is upward, so the telescopic rod will use the inclined surface of this pressure plate to push the top rod 38 against the arc shell 310 upward. At this time, the teeth on the inner wall of the arc shell 310 will match the groove at the end of the shaft, thereby achieving the effect of rotating and locking the shaft. This will keep the tightening range of the strap 2 constant and reduce the phenomenon of accidental tightening of the strap and squeezing of the binding part of the object due to external accidental contact.

[0056] Specifically, the locking assembly 3 also includes a movable shell disposed on the surface of the housing 1 and located below the locking sleeve 31. A top rod 38 is vertically slidably connected inside the movable shell. Pressure plates are fixedly connected to both sides of the surface of the top rod 38. The pressure plates are rectangular in design, and the inclined surfaces of the two pressure plates are arranged in opposite directions. The inclined surface of one of the pressure plates contacts one of the telescopic rods.

[0057] Similarly, when the locking sleeve 31 rotates counterclockwise, the previous vertical rod 37 will be moved back to the top, and the left vertical rod 37 will drive another telescopic rod to contact the left pressure plate. The inclined surface of this pressure plate is tilted downwards. Therefore, when the telescopic rod contacts the pressure plate, the pressure plate will drive the top rod 38 to move down and contact the arc-shaped shell 310 to lock the end of the shaft.

[0058] Specifically, the locking component 3 also includes a toothed groove at one end of the shaft near the arc-shaped groove 35, and an arc-shaped shell 310 fixed to the upper end of the top rod 38 is provided on the surface of the shaft. The inner wall of the arc-shaped shell 310 is designed with teeth, and the teeth are adapted to the toothed groove.

[0059] In use, when a person uses cable ties to bind an object, first, the cable tie 2 is wrapped around the object and then inserted back into the housing 1. Then, the outer end of the cable tie 2 is stretched. At this point, the lower part of the cable tie 2 will contact the wheel 32. The rotation of the wheel 32 not only improves the smoothness of the cable tie 2's stretching, but also, after the cable tie 2 is stretched to a certain length, the abutment block 34 will first limit the locking block of the wheel 32, preventing the wheel 32 from rotating backward. At this time, the locking block above the wheel 32 will engage with the teeth of the cable tie 2, locking the cable tie 2. After the person inserts the cable tie 2 into the housing 1, they twist the locking sleeve 31, causing the locking plate 39 on the surface of the locking sleeve 31 to rotate 90 degrees clockwise along the arc-shaped groove 35. At this point, the locking sleeve 31 at this end will be locked, which can prevent accidental contact by personnel during the use of the cable tie, causing the shaft to drive the wheel 32 to slide laterally from under the cable tie 2. When personnel need to loosen the cable tie, they can squeeze one of the locking sleeves 31 laterally. At this time, the wheel 32 will be misaligned with the teeth under the cable tie 2. Then, personnel can pull the cable tie 2 in the opposite direction to complete the loosening of the cable tie. When personnel reuse the cable tie in the above way, since the locking block on the surface of the wheel 32 will rotate when the cable tie 2 is inserted into the housing 1, different locking blocks can be used to complete the locking operation each time it is used, reducing the wear caused to a certain locking structure and effectively reducing the wear of the locking structure inside the cable tie.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
