Description

Technical Field

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

[0002] Plastic seals, also known as cable ties, are accessories made of plastic used to fix wires, cables and other lines. Plastic seals consist of two parts. One end is a square plastic head with a hook-shaped elastic plastic buckle inside, and the other end is a plastic seal body with serrated edges. The body can be bent through the plastic opening in the front and form a ring, which can be used to bundle cables like a trouser belt.

[0003] When using existing plastic seals, the seal and the plastic opening can only be inserted and locked in one direction. Therefore, when bundling, it is necessary to determine in advance the direction of the seal to be inserted into the plastic opening. In addition, one plastic seal can only be used for a single bundling, which causes some inconveniences when used. For example, after bundling a row of wires, another plastic seal needs to be taken out to tie the bundled wires to the external bracket; or, if a second batch of wires needs to be bundled in the same direction, another plastic seal needs to be taken out to tie the second batch of wires, and then another plastic seal needs to be taken out to tie the second batch of wires to the first batch of wires.

[0004] Based on this, in order to simplify the above-mentioned operating steps and further improve the flexibility of using the plastic seal, a double-lock core plastic seal is provided. Utility Model Content

[0005] The purpose of the utility model is to provide a double-lock-core plastic seal in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a double-lock-core plastic seal, comprising a plastic head, a cable tie assembly, and a two-way locking assembly. The plastic head is composed of a lock head, a convex slot, and a bottom slot. The convex slot and the bottom slot are opened inside the lock head and pass through both ends of the lock head. The bottom slot is distributed at the bottom end of the convex slot.

[0007] The cable tie assembly includes a cable tie and a triangular lock tooth. The cable tie is fixed to the bottom end of the lock head, and the triangular lock tooth is formed on the surface of one end of the cable tie.

[0008] The two-way locking assembly includes an elastic separator, a connecting block, a top triangular locking block, and a bottom triangular locking block;

[0009] The connecting blocks are symmetrically fixed on both sides of the middle portion of the bottom of the elastic separator, and the bottom ends of the connecting blocks are fixed to the bottom of the inner wall of the convex slot;

[0010] The top triangular locking block and the bottom triangular locking block are distributed and fixed on the top of one end of the elastic separator and the bottom of the other end of the elastic separator, and the top triangular locking block and the bottom triangular locking block are distributed in a circular shape of 180 degrees with the center of the elastic separator as the center;

[0011] The channel between the top of the elastic separator and the top of the inner wall of the convex slot is used for the cable tie end to be bent clockwise 270 degrees and then inserted, and one-way locking is achieved by the top triangular locking block and the downwardly distributed triangular locking teeth;

[0012] The channel between the bottom of the elastic separator and the bottom of the inner wall of the bottom slot is used for the cable tie end to be bent 270 degrees counterclockwise and then inserted, and one-way locking is achieved by the bottom triangular locking block and the upwardly distributed triangular locking teeth.

[0013] As a further solution of the present invention: two cable ties are provided, the two cable ties are distributed horizontally and flush, and the two cable ties are connected by a number of dotted line connection points.

[0014] As a further solution of the present invention: the side spacing of the two connecting blocks that are away from each other matches the width of the large-size slot at the bottom of the convex slot, and the small-size slot width at the top of the convex slot, the top triangular locking block and the overall width of the two cable ties and the dotted connection point match.

[0015] As a further solution of the present invention: the distance between the side surfaces of the two connecting blocks that are close to each other and the width of the bottom triangular locking block match the inner wall width of the separating convex edge, and match the overall width of the two cable ties and the dotted line connection point.

[0016] As a further solution of the present invention: a separating convex edge is formed at the center line of the top of the inner wall of the convex slot and the bottom of the inner wall of the bottom slot, and the width of the separating convex edge matches the width of the gap between the two cable ties.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] By setting up a two-way locking component, the cable tie can be inserted through from any end face of the lock head. There is no need to consider the insertion direction of the cable tie during use, making the use of the seal more convenient. In addition, the structural setting of the two cable ties used independently makes the overall seal have an "8"-shaped structure. This structural state can achieve the effect of completing two bundles with one seal and fixing the two bundled objects to each other. This operation can further improve the flexibility and applicability of the seal. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 3 In an embodiment of the present invention, a double-lock-core plastic seal includes a plastic head 1, a cable tie assembly 2, and a two-way locking assembly 3. The plastic head 1 is composed of a lock head 101, a convex slot 102, and a bottom slot 103. The convex slot 102 and the bottom slot 103 are opened inside the lock head 101 and pass through both ends of the lock head 101. The bottom slot 103 is distributed at the bottom end of the convex slot 102.

[0025] The cable tie assembly 2 includes a cable tie 201 and a triangular lock tooth 202. The cable tie 201 is fixed to the bottom end of the lock head 101, and the triangular lock tooth 202 is formed on the surface of one end of the cable tie 201.

[0026] The two-way locking assembly 3 includes an elastic separator 301, a connecting block 302, a top triangular locking block 303, and a bottom triangular locking block 304;

[0027] The connecting blocks 302 are symmetrically fixed on both sides of the middle portion of the bottom of the elastic separator 301, and the bottom ends of the connecting blocks 302 are fixed to the bottom of the inner wall of the convex slot 102;

[0028] The top triangular locking block 303 and the bottom triangular locking block 304 are distributed and fixed at the top of one end of the elastic separator 301 and the bottom of the other end of the elastic separator 301, and the top triangular locking block 303 and the bottom triangular locking block 304 are distributed in a 180-degree circle with the center of the elastic separator 301 as the center.

[0029] The channel between the top of the elastic separator 301 and the top of the inner wall of the convex slot 102 is used for the cable tie 201 to be inserted after being bent clockwise 270 degrees. The top triangular locking block 303 and the downwardly distributed triangular locking teeth 202 achieve one-way locking.

[0030] The channel between the bottom of the elastic separator 301 and the bottom of the inner wall of the bottom slot 103 is used for the end of the cable tie 201 to be bent 270 degrees counterclockwise and then inserted, and one-way locking is achieved by the bottom triangular locking block 304 and the upwardly distributed triangular locking teeth 202;

[0031] Two cable ties 201 are provided, and the two cable ties 201 are arranged horizontally and flush with each other, and the two cable ties 201 are connected by a number of dotted line connection points 203;

[0032] The side spacing of the two connecting blocks 302 away from each other matches the width of the large-size slot at the bottom of the convex slot 102, and the small-size slot width at the top of the convex slot 102 and the top triangular locking block 303 match the overall width of the two cable ties 201 and the dotted connection point 203.

[0033] In this embodiment, the plastic seal has the following two usage modes:

[0034] The first method is to use the two cable ties 201 as a whole. At this time, after the end of the cable tie 201 is flipped 270 degrees clockwise (it should be noted that the end of the cable tie 201 is vertically facing downwards by default), its triangular locking teeth 202 are in a downward state, and the end of the cable tie 201 can be inserted into the gap between the top of the elastic separator 301 and the top of the inner wall of the convex slot 102. During this process, the downwardly distributed triangular locking teeth 202 will contact and squeeze the inclined surface of the top triangular locking block 303. At this time, the elastic separator 301 is bent and deformed downward, so that the cable tie 201 can pass through the lock head 101 smoothly. When the triangular locking block 303 is aligned with the gap between the two adjacent triangular locking teeth 202, the elastic separator 301 is reset under its own elastic force, and the triangular locking block 303 is stuck in the middle of the two triangular locking teeth 202, so that the vertical end face of the triangular locking block 303 is in contact with the vertical end face of the rear triangular locking tooth 202, so that one-way locking can be achieved;

[0035] When the end of the cable tie 201 is turned 270 degrees counterclockwise, its triangular locking teeth 202 are facing upward, and the end of the cable tie 201 can be inserted into the gap between the bottom of the elastic separator 301 and the bottom of the inner wall of the bottom slot 103. At this time, the bottom triangular locking block 304 can achieve one-way locking with the triangular locking teeth 202. Through the cooperation of the above multiple parts, the cable tie 201 can be inserted through any end face of the lock head 101. There is no need to consider the insertion direction of the cable tie 201 during use, making the use of the seal more convenient;

[0036] The second method is to use the two cable ties 201 as two independent individuals. At this time, the dotted connection point 203 is pulled apart to separate the two cable ties 201. Then, one cable tie 201 is turned 270 degrees clockwise and inserted from the upper part of the convex slot 102 to pass through the lock head 101, and the other cable tie 201 is turned 270 degrees counterclockwise and inserted from the bottom slot 103 to pass through the lock head 101. At this time, the overall seal is similar to an "8"-shaped structure. This structural state can achieve the effect of completing two bundlings with one seal and fixing the two bundled objects to each other. This operation can further improve the flexibility and applicability of the seal.

[0037] Please refer to Figures 1 to 3 A separating convex edge 104 is formed at the center line of the top of the inner wall of the convex slot 102 and the bottom of the inner wall of the bottom slot 103 . The width of the separating convex edge 104 matches the width of the gap between the two cable ties 201 .

[0038] In this embodiment, the separating convex edge 104 can separate the top of the convex slot 102 and the bottom slot 103 into two channels. When the two cable ties 201 are divided into two independent individuals for use, the two channels can be suitable for inserting a single cable tie 201, thereby limiting the position of the single cable tie 201 and preventing the single cable tie 201 from deviating and shaking inside the convex slot 102 and the bottom slot 103, thereby ensuring the stable use of the seal.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
