Description

Technical Field

[0001] The utility model relates to the technical field of plastic part connection structures, in particular to a plastic buckle which is convenient to replace. Background Art

[0002] In the prior art, plastic buckles can be used to easily and effectively fix and install the fixing parts, and the cost is low and the performance is good, so they are widely used at present. However, during use, the performance of plastic buckles still needs to be improved: in the traditional matching scheme of plastic parts connection, the existing buckle structure makes it difficult to break the buckle when the parts are disassembled, which makes the buckle easy to break, and finally affects the maintenance performance of the product; some other buckle rubbing structures will cause a large number of screws to be exposed on the surface of the parts, affecting the appearance of the product.

[0003] After searching, the Chinese patent application No. 202320676641.3 discloses a convenient plastic buckle, which includes a support plate, a body sheet metal, a fixed structure, a plastic buckle structure and a baffle structure. Two support blocks are fixedly connected on the top outer wall of the support plate, and a plastic buckle structure is provided on the top of the support block. The convenient plastic buckle in the above patent has the following shortcomings:

[0004] Although the threaded rod is rotated downward to push the clamping pieces to open, so that the distance between the clamping pieces is larger than the clamping groove, so that the fixing sleeve cannot be detached from the body sheet metal, the fixing belt will stretch as the number of placed wiring harnesses increases, and can be adjusted with the number of wiring harnesses, so as to facilitate the fixing of multiple automobile wiring harnesses at the same time. However, when a convenient plastic buckle is disassembled and replaced, it is necessary to first pull out the automobile wiring harness, which is a cumbersome step and is not easy to replace the plastic buckle. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and provides a plastic buckle which is convenient to replace.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A plastic buckle that is easy to replace includes a replacement mechanism, a bottom plate and a top plate, wherein the top of the bottom plate is movably connected to the replacement mechanism, the top of the replacement mechanism is movably connected to fabric one, the top of fabric one is fixedly connected to a fixed column, and the top of fabric one is fixedly connected to an isolation baffle.

[0008] As a further solution of the utility model: the top of the fixing column is fixedly connected with an upper locking tooth, and the circumferential surface of the fixing column is movably connected with a lower locking tooth.

[0009] As a further solution of the utility model: a clamping column is fixedly connected to the bottom of the top plate, the circumferential surface inside the clamping column is movably connected to the limiting clamping teeth, and a partition is arranged on the circumferential surface inside the clamping column.

[0010] As a further solution of the utility model: a spring No. 1 is fixedly connected to the inner circumference of the clamping column, and the limit clamping teeth and the upper clamping teeth and the lower clamping teeth are mutually clamped.

[0011] As a further solution of the utility model: a slide groove is provided at the bottom of the fabric, a clamping groove is provided inside the slide groove, and a blocking plate is fixedly connected to the circumferential surface inside the clamping groove.

[0012] As a further solution of the utility model: the replacement mechanism includes a shovel block, a center plate, a barrier block, and an arc strip. The replacement mechanism is movably connected to the bottom of fabric one and the top of the top plate, respectively. The center plate is movably connected between fabric one and the bottom plate, and the arc strip is fixedly connected to the inside of the center plate.

[0013] As a further solution of the utility model: the shovel block is fixedly connected to one end of the arc strip, the blocking block is fixedly connected to the other end of the arc strip, a No. 2 spring is fixedly connected to the top of the bottom plate, and the blocking block and the blocking plate are clamped with each other.

[0014] Compared with the prior art, the utility model provides a plastic buckle that is easy to replace and has the following beneficial effects:

[0015] 1. The utility model discloses a plastic buckle which is easy to replace. The plastic buckle can be replaced through a replacement mechanism movably connected to the top of the bottom plate. At the same time, an isolation baffle fixedly connected to the top of the fabric can prevent foreign objects from blocking the buckling of the plastic buckle when the plastic buckle is buckled, thereby solving the problem of replacing the plastic buckle.

[0016] 2. This is a plastic buckle that is easy to replace. The upper clamping tooth is pressed into the clamping column, so that a pair of limit clamping teeth in the clamping column squeeze the No. 1 spring inward, and the limit clamping teeth are stuck in the gap between the upper clamping teeth and the lower clamping teeth to fix the plastic buckle. The upper clamping tooth is pressed into the clamping column again to allow the limit clamping tooth to drive the lower clamping tooth to move upward, and the plastic body is disassembled. At the same time, a partition fixedly connected by the circumferential surface inside the clamping column prevents the limit clamping tooth from rushing out of the interior of the clamping column due to the elastic potential energy of the No. 1 spring during movement, thereby solving the problem of fixing the limit clamping tooth.

[0017] 3. This is a plastic buckle that is easy to replace. Through the slide groove provided at the bottom of the fabric, the replacement mechanism can slide at the bottom of the fabric, thereby solving the rotation problem of the replacement mechanism.

[0018] 4. This is a plastic buckle that is easy to replace. By rotating the center plate clockwise, the blocking block at one end of the arc strip is engaged with the blocking plate on the inner circumferential surface of the slot to fix the replacement mechanism. When the blocking plate is engaged with the blocking block, the elastic potential energy of the No. 2 spring makes the blocking plate and the blocking block more firmly engaged. At the same time, by rotating the center plate counterclockwise, the shovel block at one end of the arc strip separates the No. 2 spring on the top of the bottom plate from the center plate, thereby realizing the disassembly of the replacement mechanism. Therefore, the disassembly and fixation problems of the replacement mechanism are solved.

[0019] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. The utility model has a simple structure and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] like Figure 2 , Figure 3 As shown, the top of the fixing column 6 is fixedly connected with an upper locking tooth 5, and the circumferential surface of the fixing column 6 is movably connected with a lower locking tooth 7.

[0032] like Figure 2 , Figure 4 , Figure 7 When the plastic buckle is installed, the upper clamping teeth 5 are pressed into the clamping column 4, so that a pair of limiting clamping teeth 12 in the clamping column 4 squeeze the No. 1 spring 10 inwardly, and the limiting clamping teeth 12 are stuck in the gap between the upper clamping teeth 5 and the lower clamping teeth 7 to fix the plastic buckle, and the upper clamping teeth 5 are pressed into the clamping column 4 again to allow the limiting clamping teeth 12 to drive the lower clamping teeth 7 to move upward, and the plastic body is disassembled. At the same time, the partition 11 fixedly connected to the circumferential surface of the inner side of the clamping column 4 is prevented from rushing out of the inner side of the clamping column 4 by the elastic potential energy of the No. 1 spring 10 during movement, thereby solving the fixing problem of the limiting clamping teeth 12.
