Description

Technical Field

[0001] The utility model relates to the technical field of cable ties, in particular to a cable tie. Background Art

[0002] Gas wall-mounted boilers have powerful home central heating functions, which can meet the heating needs of multiple rooms. They can also provide hot water bathing functions, so they are very popular among users.

[0003] The signal wires or wires of the wall-mounted boiler are usually tied and locked with cable ties. The main components of the cable tie include the cable tie body and the cable tie head. The cable tie body passes through the hole of the cable tie head and is locked with wedge-shaped teeth in opposite directions. Since the wedge-shaped teeth are unidirectional, the cable tie will not loosen in the reverse direction when it is tied.

[0004] However, as the structure of wall-mounted boilers becomes increasingly lean and compact, the operating space is limited; and because the cable ties are in close contact with the wiring harness, when faced with fault maintenance in the later stage, when tools are used to remove the cable ties to untie the wiring harness, it is very likely to cause damage to the wiring harness, or even cause a short circuit in the line, posing a safety hazard.

[0040] See also Figure 1-Figure 3 , this embodiment provides a cable tie.

[0041] Optionally, the cable tie can be applied to a wall-mounted boiler to bundle and lock the wire harness on the wall-mounted boiler. Of course, in other embodiments, the cable tie can also be applied to other products, such as refrigerators or cars.

[0042] Specifically, the cable tie includes a cable tie head 1 and a cable tie body 2 .

[0043] Among them, a bite channel 11 is provided on the tie head 1 along a first direction and passes through the tie head 1. A tearing portion 12 is provided on the tie head 1. The tearing portion 12 extends along the first direction to both ends of the bite channel 11. The tearing portion 12 can be torn along the first direction to open the bite channel 11.

[0044] One end of the belt body 2 is fixedly connected to the cable tie head 1 , and the other end is a free end that can pass through the bite channel 11 and be locked with the cable tie head 1 .

[0045] When the engaging passage 11 is opened by the tearing portion 12 , the locking between the other end of the strap body and the cable tie head 1 is released.

[0046] When the cable tie provided in this embodiment needs to bind and lock the wire harness, the belt body 2 is wrapped around the wire harness to be bound and locked, and then the free end of the belt body 2 is passed through the bite channel 11 and locked with the cable tie head 1.

[0047] When the wiring harness needs to be repaired, the tearing portion 12 is torn open. Since the extending direction of the tearing portion 12 is the same as the extending direction of the bite channel 11, when the tearing portion 12 is torn open, the side of the bite channel 11 originally enclosed forms an opening at the tearing portion 12, thereby opening the bite channel 11, and the other end of the belt body 2 can be detached from the opening, releasing the enclosure formed by the belt body 2 and the cable tie head 1, so that the wiring harness can be freed from the restraint of the belt body 2, thereby quickly realizing the untying of the wiring harness.

[0048] In order to tear the tear portion 12 more conveniently and with less effort, in one embodiment, a hole 121 communicating with the bite channel 11 is provided on the tear portion 12 .

[0049] In one embodiment, the thickness of the tearing portion 12 is less than the thickness of the side wall of the cable tie head 1. With such a configuration, the tearing portion 12 can be torn open more conveniently and labor-savingly.

[0050] Specifically, the tearing portion 12 is disposed on the side wall of the cable tie head 1 , and the thickness of the tearing portion 12 is smaller than the thickness of the side wall of the cable tie head 1 .

[0051] Preferably, the tearing portion 12 is provided with a hole 121 communicating with the bite channel 11, and the thickness of the tearing portion 12 is less than the thickness of the side wall of the cable tie head 1. Figure 3 An arc-shaped groove is provided on the side wall of the cable tie head 1 to form a tearing portion 12. The bottom of the arc-shaped groove is the tearing portion 12, where the material thickness is the thinnest. The setting of the hole 121 makes it easier to tear the tearing portion 12.

[0052] Optionally, a plurality of holes 121 are arranged at intervals on the tear portion 12 , and the plurality of holes 121 are arranged sequentially along the first direction.

[0053] In order to further facilitate maintenance personnel to tear the tearing portion 12 with the help of tools, two tearing portions 12 are provided on the same side wall of the cable tie head 1, and the two tearing portions 12 are spaced apart along the second direction; the cable tie head 1 is provided with a groove 18 located between the two tearing portions 12;

[0054] Alternatively, two tearing portions 12 are provided on the opposite side walls of the cable tie head 1, and the two tearing portions 12 on the same side wall of the cable tie head 1 are spaced apart along the second direction; the cable tie head 1 is provided with a groove 18, and the groove 18 is located between the two tearing portions 12 on the same side wall of the cable tie head 1.

[0055] With such arrangement, when the wire harness needs to be tied, the maintenance personnel hold the needle-nosed pliers, and the pointed ends of the needle-nosed pliers are clamped on the position where the groove 18 is provided on the cable tie head 1. The groove 18 can limit the pointed ends of the needle-nosed pliers, making it convenient for the maintenance personnel to clamp the side wall of the cable tie head 1 and apply force.

[0056] Specifically, the cable tie head 1 includes a first side wall 13 , a second side wall 14 , a third side wall 15 and a fourth side wall 16 which are connected end to end in sequence, and the first side wall 13 , the second side wall 14 , the third side wall 15 and the fourth side wall 16 are jointly arranged to form the bite channel 11 .

[0057] One end of the belt body 2 is fixedly connected to the outer surface of the first side wall 13 of the cable tie head 1 ; the tearing portion 12 is arranged on the second side wall 14 and / or the fourth side wall 16 .

[0058] Preferably, two tearing portions 12 are provided on the second side wall 14, the two tearing portions 12 are spaced apart along the second direction, and a groove 18 is provided on the second side wall 14 between the two tearing portions 12; two tearing portions 12 are provided on the fourth side wall 16, the two tearing portions 12 are spaced apart along the second direction, and a groove 18 is provided on the fourth side wall 16 between the two tearing portions 12. The second direction and the first direction are perpendicular to each other.

[0059] When the maintenance personnel need to untie the wire harness, the maintenance personnel hold the needle-nosed pliers, and the pointed ends of the needle-nosed pliers clamp the second side wall 14 or the fourth side wall 16, and the pointed ends are located in the groove 18 to facilitate the maintenance personnel to apply force. Then the maintenance personnel grasp and pull the needle-nosed pliers, and under the force of the needle-nosed pliers, the two tearing parts 12 of the same side wall will be torn at the same time, and the part between the two tearing parts 12 of the side wall will be separated from the cable tie head 1, and an opening is formed on the side of the bite channel 11, and the wire harness can be separated from the cable tie from the opening.

[0060] In one of the embodiments, in order to ensure that the free end of the belt body 2 passes through the bite channel 11 and can be stably locked with the cable tie head 1, a belt body locking piece 111 is provided in the bite channel 11, one end of the belt body locking piece 111 is fixedly connected to the first inner wall of the bite channel 11, and the other end of the belt body locking piece 111 can press the belt body 2 against the second inner wall opposite to the bite channel 11.

[0061] Specifically, the belt locking piece 111 is tilted relative to the first direction. One end of the belt locking piece 111 is fixed to the inner surface of the third side wall 15 , and the other end of the belt locking piece 111 is a free end, which is tilted relative to the first direction and extends toward the first side wall 13 .

[0062] Specifically, after the belt body 2 is wrapped around the wire harness and then passes through the bite channel 11, the inner side wall of the bite channel 11 and the belt body locking piece 111 can exert two forces in opposite directions on the belt body 2, thereby stably locking the belt body 2 and the cable tie head 1 together.

[0063] Further, see Figure 1 and Figure 3 In order to guide and limit the belt body 2 passing through the bite channel 11, in one embodiment, a belt body limiting piece 112 is also provided in the bite channel 11, and a belt body limiting piece 112 is provided on both sides of the belt body locking piece 111, and a belt body limiting groove 113 is formed between the two belt body limiting pieces 112 and the belt body locking piece 111.

[0064] When the belt body 2 passes through the bite channel 11, the belt body 2 can be passed through the bite channel 11 along the belt body limiting groove 113. The belt body locking piece 111 locks the belt body 2, and the two belt body limiting pieces 112 can limit the belt body 2 to prevent the belt body 2 from tilting.

[0065] In one of the embodiments, in order to fix the cable tie on the sheet metal of the wall-mounted boiler, the cable tie also includes a fixing portion 3, which is arranged at the end of the cable tie head 1 that is away from the belt body 2, and the fixing portion 3 includes a first clamping member 31 and a second clamping member 32 that are relatively arranged, and a clamping space 33 is formed between the first clamping member 31 and the second clamping member 32.

[0066] The second clamping member 32 is capable of compression deformation, so that the second clamping member 32 can be deformed and pass through the opening on the sheet metal member to be installed.

[0067] Specifically, the fixing portion 3 is disposed on the outer side of the third side wall 15 .

[0068] Exemplarily, on a wall-mounted boiler, the first clamping member 31 and the second clamping member 32 clamp a plate member, such as a sheet metal member, on the wall-mounted boiler to fix the cable tie on the product.

[0069] In one embodiment, see Figure 1 and Figure 3 The fixing portion 3 also includes an adjusting rod 34 connected to the cable tie head 1, the first clamping member 31 is fixedly arranged on the cable tie head 1, and the second clamping member 32 is installed on the adjusting rod 34, and the position of the second clamping member 32 is adjustable along the axial direction of the adjusting rod 34 to adjust the size of the clamping space 33.

[0070] Specifically, taking the wiring harness of a wall-mounted boiler as an example, an opening is provided on the sheet metal of the wall-mounted boiler to facilitate the fixing of the tie. Optionally, the opening on the sheet metal is a rectangular hole.

[0071] The second clamping member 32 is capable of compression deformation, so that the second clamping member 32 can be deformed and pass through the opening on the sheet metal member to be installed.

[0072] The installation position of the second clamping member 32 on the adjusting rod 34 is adjustable along the axial direction of the adjusting rod 34 to adjust the size of the clamping space 33. With such arrangement, the cable tie can adapt to sheet metal parts of different thicknesses.

[0073] The second clamping member 32 can be compressed and deformed so as to pass through the opening on the sheet metal part; the second clamping member 32 can abut against the sheet metal part in the restored state.

[0074] The first clamping member 31 cannot pass through the opening on the sheet metal member. The adjusting rod 34 can pass through the opening on the sheet metal member.

[0075] In the initial installation state, the second clamping member 32 is in a compressed, folded and deformed state; then, the cable tie head 1 is arranged opposite to the opening on the sheet metal and the cable tie head 1 is placed on one side of the sheet metal, the second clamping member 32 is passed through the opening on the sheet metal until the first clamping member 31 is against the sheet metal, and then the second clamping member 32 is restored to its original state, and a clamping space 33 is formed between the second clamping member 32 and the first clamping member 31, and the sheet metal is clamped by the second clamping member 32 and the first clamping member 31.

[0076] Furthermore, in one of the embodiments, in order to adjust the installation position of the second clamping member 32 on the adjusting rod 34, a plurality of latching positions 341 are arranged at intervals on the adjusting rod 34 along the axial direction of the adjusting rod 34, and the second clamping member 32 can be selectively engaged with one of the latching positions 341.

[0077] Exemplarily, the number of the latching positions 341 is 2-5, such as 2, 3, 4 or 5. Of course, in other embodiments, the number of the latching positions 341 can also be set as required, and no excessive restrictions are made here.

[0078] The second clamping member 32 can be selectively engaged with one of the clamping positions 341, so as to adjust the distance between the second clamping member 32 and the first clamping member 31, that is, adjust the gap size of the clamping space 33, so that the cable tie can adapt to sheet metal parts of different thicknesses.

[0079] Specifically, see Figure 3 and Figure 5In one embodiment, the second clamping member 32 is provided with an avoidance hole 321 and a card slot 322 , and the adjustment rod 34 can rotate relative to the cable tie head 1 so that the card position 341 passes through the avoidance hole 321 and is engaged with the card slot 322 .

[0080] Specifically, the adjustment rod 34 includes a rod body 342 and a rotating head 343, and the rotating head 343 is fixedly arranged at the free end of the rod body 342. The clamping position 341 is arranged on the side of the rod body 342. Further, the clamping position 341 includes clamping wings arranged on both sides of the rod body 342, and the two clamping wings of the same clamping position 341 are symmetrically arranged relative to the rod body 342.

[0081] A rotating head mounting position 17 is provided on the cable tie head 1, and a hemispherical groove is provided at the rotating head mounting position 17, and the rotating head 343 is sleeved into the hemispherical groove and can rotate relative to the hemispherical groove under the action of an external force. More specifically, the rotating head mounting position 17 is provided on the outer side of the third side wall 15.

[0082] Specifically, the first clamping member 31 is fixedly disposed on the outer periphery of the rotating head installation position 17 .

[0083] Exemplarily, when it is necessary to adjust the gap size of the clamping space 33, the adjusting rod 34 is rotated so that the two clamping wings of the same clamping position 341 are arranged opposite to the avoidance hole 321. At this time, the two clamping wings of the same clamping position 341 can pass through the avoidance hole 321 and move the second clamping member 32 along the axial direction of the rod body 342 to adjust the distance between the second clamping member 32 and the first clamping member 31; when the distance is adjusted to the right position, the adjusting rod 34 is rotated to rotate the two clamping wings of the clamping position 341 here until they are engaged in the clamping groove 322.

[0084] Specifically, the restored state of the second clamping member 32 is the clamping state; in the clamping state, the second clamping member 32 is a frame-shaped structure with a trapezoidal cross section. The material of the second clamping member 32 can be PP or PC.

[0085] The second clamping member 32 can be transformed into a long frame structure after being compressed, folded and deformed, so as to smoothly pass through the opening on the sheet metal member.

[0086] Specifically, see Figure 1 and Figure 3 The second clamping member 32 includes an upper base plate 323 and a lower base plate 325 that are arranged opposite to each other, and also includes two side plates 324; the upper base plate 323, one side plate 324, the lower base plate 325 and the other side plate 324 are connected end to end in sequence and can be enclosed to form a trapezoidal space, which is in a clamping state. The lower base plate 325 and the first clamping member 31 are jointly enclosed to form a clamping space 33.

[0087] Since the distance between the upper base plate 323 and the lower base plate 325 may need to change adaptively when adjusting the position of the second clamping member 32, the above-mentioned structure of the second clamping member 32 is adopted so that there is an adjustment margin for the distance between the upper base plate 323 and the lower base plate 325, which facilitates the position adjustment of the second clamping member 32.

[0088] The upper bottom plate 323 can pass through the opening on the sheet metal component, but the lower bottom plate 325 cannot pass through the opening on the sheet metal component.

[0089] Further, see Figure 3 and Figure 4 The lower bottom plate 325 is provided with deformation grooves 3251 on both sides of the rod body 342 to facilitate the folding deformation of the second clamping member 32 .

[0090] Further optionally, the distance between the two deformation grooves 3251 is the same as the length of the upper base plate 323; when the second clamping member 32 needs to be compressed and deformed, the two lower corners of the trapezoid formed by the second clamping member 32 are squeezed, and the angles of the two lower corners are deformed into flat angles, so that the second clamping member 32 is deformed to form a long frame structure. The long frame structure can pass through the opening on the sheet metal. After the long frame structure passes through the opening, the upper base plate 323 is pushed toward the cable tie head 1. Under the combined action of the thrust and the sheet metal, the original two lower corners are restored to the lower corners, and the lower base plate 325 is also restored. The second clamping member 32 is restored to form a trapezoidal structure, and the lower base plate 325 can abut against the sheet metal, thereby realizing the installation of the cable tie on the sheet metal.

[0091] The avoidance hole 321 is a straight hole formed on the upper bottom plate 323; the clamping slot 322 is a straight slot formed on the surface of the upper bottom plate 323 facing the lower bottom plate 325. The avoidance hole 321 and the clamping slot 322 are intersectingly formed. Preferably, the avoidance hole 321 and the clamping slot 322 are in a "cross" shape.

[0092] Exemplarily, the cable tie provided in this embodiment is used as follows during work:

[0093] Adjust the distance between the lower base plate 325 and the first clamping member 31 according to the thickness of the sheet metal;

[0094] Fix the cable tie on the sheet metal: fold the second clamping member 32 to be a long frame structure, and after the long frame structure passes through the opening of the sheet metal, restore the second clamping member 32 to a trapezoidal structure;

[0095] After the belt body 2 is wrapped around the wire harness, it passes through the engaging channel 11 along the belt body limiting groove 113 .

[0096] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0097] The specific contents of the above specific implementations only express several implementations of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
