Description

Technical Field

[0001] The utility model relates to the field of double-hole plastic seals, in particular to a plastic seal with double lock holes. Background Art

[0002] The double-hole plastic seal is also called a double-hole plastic cable tie, which has two locking holes and two tying strips. The locking holes and the tying strips are provided with interlocking triangular blocks. The triangular blocks in the locking holes are connected by elastic plastic. The triangular blocks in the locking holes drive the elastic plastic to deform under the thrust of the triangular blocks of the tying strips. The two triangular blocks are misaligned. When the thrust disappears, the two triangular blocks bite to achieve the locking function.

[0003] Double-hole cable ties are a form of plastic cable ties. This type of cable tie is generally used to tighten adjacent wire harnesses, and the adjacent distance cannot be too large. Therefore, in actual operation, the spacing between adjacent wire harnesses is usually slightly larger. At this time, the operator can only use the double-hole cable tie to perform cable bundling operations by pulling the wire harness offset. It is impossible to bundle adjacent wire harnesses that are vertical or inclined, and the scope of application is relatively limited. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 to Figure 3In the embodiment of the utility model, a plastic seal with double lock holes includes a lock block 1, which is divided into two symmetrical parts, and the two parts of the lock block 1 are not connected to each other, and one end of the two parts of the lock block 1 that are far away from each other is integrally injection molded with a tie strip 2;

[0024] Two limiting mechanisms are connected between the two locking blocks 1, and the two limiting mechanisms extend from one end of one part of the locking block 1 to one end of the other part of the locking block 1;

[0025] And the two limiting mechanisms are misaligned with the lock hole 3;

[0026] Two unbroken limiting mechanisms are used to limit the two parts of the locking block 1 to be connected together;

[0027] A disconnected limiting mechanism and another undisconnected limiting mechanism are used to realize relative rotation of two parts of the locking block 1;

[0028] The two disconnected limiting mechanisms are used to change a double-hole plastic seal into two single-hole plastic seals.

[0029] In this embodiment: when the distance between two adjacent wire harnesses is close and meets the bundling distance of the double-hole cable tie, there is no need to disconnect the limiting mechanism and it can be used directly;

[0030] When the distance between two adjacent harnesses is relatively far, since the locking block 1 cannot be adjusted, one of the tie strips 2 cannot effectively tighten the harness;

[0031] At this time, you can use tools (such as needle-nosed pliers) to disconnect the two limit mechanisms. At this time, the two parts of the locking block 1 are separated, so that a double-hole cable tie is changed into two single-hole cable ties, and the two wiring harnesses can be tightened separately;

[0032] When two adjacent wiring harnesses are in a vertical or inclined state, a tool is used to disconnect a limiting mechanism. At this time, the two parts of the locking block 1 can be relatively rotated through a limiting mechanism, and the overlapping points of the two wiring harnesses in a vertical or inclined state can be bundled, thereby achieving the purpose of a wider range of applications.

[0033] Please refer to Figure 1 , Figure 2 and Figure 3 The limiting mechanism includes a connecting hole 4, which passes from one end of one part of the locking block 1 to one end of another part of the locking block 1;

[0034] The inner wall of the connecting hole 4 is provided with a plastic strip 6, the two ends of the plastic strip 6 are flush with the ends of the two parts of the locking block 1 that are away from each other, and the two ends of the plastic strip 6 are integrally formed with an anti-slip portion 5, and the diameter of the anti-slip portion 5 is larger than the end diameter of the plastic strip 6;

[0035] The limiting mechanism includes a thin straight portion 8 formed in the middle section of the outer wall of the plastic strip 6 . The diameter of the thin straight portion 8 is smaller than the diameter of the plastic strip 6 . Conical surfaces 7 are formed on the outer wall of the plastic strip 6 at both ends of the thin straight portion 8 .

[0036] In this embodiment: when the limiting mechanism needs to be disconnected, needle-nosed pliers are used to insert into the space between the two parts of the locking block 1, and then the needle-nosed pliers are used to cut off the thin straight portion 8. Since the diameter of the thin straight portion 8 is relatively thin, the switching process is relatively convenient, and the conical surface 7 can make a good transition between the surface of the plastic strip 6 and the thin straight portion 8;

[0037] According to the use requirements, one thin straight portion 8 or two thin straight portions 8 can be cut off to achieve different functions. The anti-slip portion 5 and the plastic strip 6 are an integrated structure. After the plastic strip 6, which is originally in a columnar state, is inserted into the connecting hole 4, the end of the plastic strip 6 is heated to deform it, and then the anti-slip portion 5 is formed by extrusion, which can prevent the plastic strip 6 from separating from the connecting hole 4.

[0038] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
