DETAILED DESCRIPTION

[0025] 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.

[0026] See also Figures 1 to 4 In the embodiment of the utility model, a bidirectionally usable plastic cable tie comprises a cable tie body 1 composed of a lock head 101 and a tie strip 102. The tie strip 102 is fixed to the bottom end of the lock head 101. A plug-in slot 103 penetrating through both ends of the lock head 101 is provided inside the lock head 101. Bidirectional self-locking units 2 are distributed at both ends of the tie strip 102 and inside the plug-in slot 103. The bidirectional self-locking units 2 are used to realize bidirectional plug-in self-locking between the tie strip 102 and the lock head 101.

[0027] The two-way self-locking unit 2 includes a first self-locking unit and a second self-locking unit;

[0028] The first self-locking unit and the second self-locking unit are respectively used to realize one-way self-locking during the insertion of the tie strip 102 in two different directions;

[0029] The first self-locking unit includes a first 7-shaped spring block 201 and a middle oblique tooth groove 203;

[0030] The first 7-shaped spring block 201 is fixed at the middle position of the bottom of the inner wall of the plug slot 103, and the top of the horizontal part of the first 7-shaped spring block 201 is integrally formed with oblique teeth;

[0031] The middle oblique tooth groove 203 is integrally formed at the middle of one end of the outer wall of the tie strip 102. When the tie strip 102 is bent and inserted from one end of the tie strip 102 through the insertion slot 103, the middle oblique tooth groove 203 is in a downward state and engages with the first 7-shaped spring block 201, so as to realize the one-way self-locking of the tie strip 102.

[0032] The first self-locking unit includes a second 7-shaped spring block 202 and a side oblique tooth groove 205;

[0033] The second 7-shaped spring block 202 is fixed to the bottom of the inner wall of the plug slot 103 with the first 7-shaped spring block 201 as the center, and the top of the lateral part of the second 7-shaped spring block 202 is integrally formed with oblique teeth;

[0034] The side bevel grooves 205 are symmetrically fixed on both sides of the end of the tie strip 102 away from the middle bevel groove 203. When the tie strip 102 is bent and inserted from the other end of the tie strip 102 through the insertion slot 103, the side bevel grooves 205 are in a downward state and engage with the second 7-shaped spring block 202, so as to realize the one-way self-locking of the tie strip 102.

[0035] The oblique teeth on the first 7-shaped spring block 201 and the second 7-shaped spring block 202 are in opposite directions, and the vertical cross-sectional notches of the middle oblique tooth groove 203 and the side groove 204 are symmetrical about the center line of the tie strip 102 .

[0036] In this embodiment: when the cable tie is in use, the tie strip 102 can pass through the lock head 101 from either end and can be self-locking. Compared with the traditional structure that can only be inserted in one direction and self-locking, it is more flexible and convenient to use;

[0037] When the tie strip 102 passes through the lock head 101, the structure of the two-way self-locking unit changes as follows:

[0038] When the tie strip 102 is bent to the point where the middle oblique tooth groove 203 faces downward, after the tie strip 102 is inserted into the plug slot 103 from one end of the lock head 101, the middle oblique tooth groove 203 contacts and squeezes the top oblique teeth of the first 7-shaped spring block 201, causing the first 7-shaped spring block 201 to deform, so that the tie strip 102 can smoothly pass through the plug slot 103. When the tie strip 102 stops being tightened, the first 7-shaped spring block 201 will reset under its own elastic force. At this time, the top oblique teeth of the first 7-shaped spring block 201 are engaged with the middle oblique tooth groove 203, realizing the one-way self-locking of the tie strip 102.

[0039] When the tie strip 102 is bent until the side bevel groove 205 faces downward, after the tie strip 102 is inserted into the plug-in slot 103 from the other end of the lock head 101, the side bevel groove 205 contacts and squeezes the top bevel teeth of the second 7-shaped spring block 202, causing the second 7-shaped spring block 202 to deform, so that the tie strip 102 can smoothly pass through the plug-in slot 103. When the tie strip 102 stops being tightened, the second 7-shaped spring block 202 will reset under the action of its own elastic force. At this time, the top bevel teeth of the second 7-shaped spring block 202 are engaged with the side bevel groove 205, realizing the one-way self-locking of the tie strip 102.

[0040] Please refer to Figures 1 to 4The first self-locking unit further includes a side groove 204, which is symmetrically formed at one end of the outer wall of the tie bar 102 with the middle oblique tooth groove 203 as the center, and is used for preventing the tie bar 102 from contacting the second 7-shaped spring block 202 when the tie bar 102 is self-locked with the first 7-shaped spring block 201 through the middle oblique tooth groove 203;

[0041] The second self-locking sheet further includes a middle groove 206, which is distributed between the two side bevel grooves 205 and is integrally formed at the other end of the outer wall of the tie bar 102, so that when the tie bar 102 is self-locked with the second 7-shaped spring block 202 through the side bevel grooves 205, the tie bar 102 does not contact the first 7-shaped spring block 201;

[0042] Two through grooves 104 are symmetrically formed on the top of the inner wall of the insertion groove 103 . The through grooves 104 penetrate through both ends of the lock head 101 . The through grooves 104 and the second 7-shaped spring block 202 are aligned in the vertical direction.

[0043] In this embodiment: through the structural arrangement of the side groove 204 and the middle groove 206, the first self-locking unit and the second self-locking unit do not interfere with each other, thereby ensuring the self-locking stability of the tie strip 102 during the bidirectional insertion process;

[0044] When the tie strip 102 is self-locked with the first 7-shaped spring block 201 through the middle oblique tooth groove 203 , the side oblique tooth groove 205 is located inside the through groove 104 , thus ensuring that the tie strip 102 passes through the plug-in groove 103 smoothly.

[0045] 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.
