Description

Technical Field

[0001] The utility model relates to the technical field of plastic fasteners, in particular to a snap-on plastic part. Background Art

[0002] The snap fastener is the simplest, fastest, lowest cost and most environmentally friendly way to assemble plastic parts. There is no need to tighten screws when assembling snap fasteners. The assembly process is simple and only a simple insertion action is required to complete the assembly of two or more parts. There are many ways to classify snap fasteners. According to the shape of the snap fastener, the commonly used snap fasteners can be divided into straight arm snap fasteners, L-shaped snap fasteners, U-shaped snap fasteners and circumferential snap fasteners.

[0003] At present, most of the snap-on structures are relatively simple. If the structure is more complicated, the opening method may be more troublesome. In addition, if the snap-on plastic parts are exposed to the outside for a long time, the snap-on parts will age faster and reduce their service life. Therefore, the technicians in this field provide a snap-on plastic part to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a snap-on plastic part is proposed. When the device is in use, the outer layer is pulled downward, and then the fixing block is placed in the inner layer, and then the outer layer is loosened, the outer layer will squeeze the snap-on block to fix the fixing block, the operation process is very simple, which is conducive to the user to operate better, and the fixing mechanism of the device is wrapped by the outer layer, and the internal mechanism will not be easily damaged, which is conducive to longer use. When the device is removed, the user pulls the outer layer downward, the No. 1 main body will drive the No. 1 rack to move downward through the partition, the No. 1 rack will drive the No. 2 rack to move upward through the gear, and the No. 1 rack will lift the fixing block upward through the support plate, which is conducive to the user to take out the fixing block more easily, and there is no need to extend the fixing block to affect the overall aesthetics of the device.

[0008] Furthermore, the first main body is slidably arranged around the inner layer, and an isolation strip is fixedly arranged around the inner part of the upper end of the first main body;

[0009] Through the above technical solution, the No. 1 main body is used to facilitate the installation of the isolation strip, partition, spring and No. 1 rack. The isolation strip is used to help reduce the entry of foreign matter into the gap between the inner layer and the outer layer to avoid getting stuck.

[0010] Furthermore, the four clamping blocks are all slidably arranged inside the periphery of the second main body, and the fixed block is clamped inside the upper end of the second main body;

[0011] Through the above technical solution, the clamping block is used to fix the fixing block, and the fixing block is used to store other items.

[0012] Furthermore, a groove is provided around the upper end of the No. 1 main body, and a No. 1 through hole is provided through the four corners of the partition;

[0013] Through the above technical solution, the groove is conducive to providing the clamping block with a movable space, and the No. 1 through hole is conducive to making the outer layer fixed more stably and not easy to fall off.

[0014] Furthermore, a fixing ring is connected between the four No. 2 racks, and a plurality of No. 2 through holes are provided through the bottom plate, and the plurality of No. 2 through holes are all aligned with the No. 1 rack and the No. 2 rack;

[0015] Through the above technical solution, the fixing ring can help prevent the four racks from shaking and make them more stable.

[0016] Furthermore, the four No. 1 racks are respectively meshed with the four gears, the four No. 2 racks are respectively meshed with the four gears, and the four No. 1 racks and the No. 2 racks are face-to-face meshed on both sides of the four gears;

[0017] The above technical solution is conducive to enabling the No. 1 rack to drive the No. 2 rack to move, so that the outer layer can also push the fixed block upward during the descending process.

[0018] Furthermore, one end of the spring is fixedly arranged at the lower end of the partition, and the other end of the spring is fixedly arranged at the upper end of the bottom plate;

[0019] Through the above technical solution, the spring is used to facilitate pushing the No. 1 main body so that the fixing block can be fixed in the inner layer.
