[0002] The plastic kit is characterized in that the entire component is formed into an arc-shaped shell with a certain thickness and is hollow inside.

[0003] The plastic kits of the LED display unit board are all assembled by screw locking, which requires a large number of operators and is inefficient. In addition, the metal screws are prone to rust and corrosion during use. For this reason, in the Chinese utility model patent with patent number CN204926707U, entitled a screw-free LED unit board plastic kit, an ultrasonic welding process is used to weld the plastic column of the mask to the hole slot of the bottom shell to meet the assembly requirements, avoid rusting caused by screw locking, and improve work efficiency. However, since the plastic column and the bottom shell are welded, the mask cannot be disassembled and assembled. When the equipment in the mask needs to be repaired, the plastic column will be damaged, so the mask needs to be replaced as a whole, which greatly increases the maintenance cost of the equipment.

[0020] 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.

[0021] refer to Figure 1-3As shown, the utility model provides a plastic kit, including: a covered base 1 and a shell 2, a plurality of plug-in posts 4 penetrating the shell 2 are provided at the edge of the base 1, a mounting bin for accommodating the plug-in posts 4 is penetrated through the shell 2, a plug-in component 3 extending into the mounting bin is provided on the plug-in post 4, and a fastener 6 engaged with the plug-in component 3 is provided in the mounting bin.

[0022] Combination Figure 4 As shown, the housing 2 is penetrated with connected grooves 5 and through holes 11 from outside to inside in sequence, the mounting chamber is formed in the grooves 5 and the through holes 11, the inner diameter of the groove 5 is larger than the inner diameter of the through hole 11, and the connector 3 and the fastener 6 are engaged in the groove 5.

[0023] As mentioned above, when using the base 1, shell 2, multiple plug-in columns 4 and multiple fasteners 6 provided by the utility model, the shell 2 is fitted with the base 1, and the plug-in column 4 is inserted into the through hole 11. At the same time, the connector 3 on the plug-in column 4 is in the groove 5. The fastener 6 is placed in the groove 5 and pressed toward one side of the connector 3, so that the fastener 6 is engaged with the connector 3. When the shell 2 needs to be removed, the fastener 6 breaks through the engagement force of the connector 3, so that the fastener 6 is detached from the connector 3, thereby realizing the reusability of the device.

[0024] Further, in order to allow the fastener 6 to wobble in the groove 5, refer to Figure 4 As shown, a rubber pad 14 is provided in the groove 5 and sleeved on the outside of the two uprights 13, and one end of the fastener 6 abuts against the rubber pad 14. When the fastener 6 is engaged with the connector 3, the rubber pad 14 fills between the fastener 6 and the groove 5 to prevent the fastener 6 from shaking in the groove 5.

[0025] Further, in order to facilitate the removal of the fastener 6 from the groove 5, refer to Figure 2 and Figure 4 As shown, the housing 2 is provided with a buckle groove 7 extending into the groove 5, and the outer wall of the fastener 6 is provided with an annular groove 9, which is arranged on the inner side of the buckle groove 7. The buckle groove 7 facilitates the insertion of a tool into the annular groove 9, and the fastener 6 is pushed outward to allow the two protrusions 12 to disengage from the clamping groove 8, so that the fastener 6 can be disengaged from the groove 5, thereby facilitating the housing 2 to be disengaged from the base 1.

[0026] In the present utility model, combined with Figure 4 As shown, the plug connector 3 of this embodiment includes two protrusions 12 symmetrically arranged in the groove 5, and a column 13 is connected between the two protrusions 12 and the plug-in column 4. The fastener 6 is provided with a slot 8 for accommodating the two protrusions 12.

[0027] As mentioned above, when using the two protrusions 12 provided by the utility model, the two protrusions 12 are directly connected to the plug-in column 4 through the two columns 13, and the two protrusions 12 are allowed to approach or move away from each other through the two columns 13. When the two protrusions 12 are close to each other, it is convenient for the two protrusions 12 to be locked in the groove 8. When the two protrusions 12 are expanded outward, it is convenient to lock the fastener 6 on the two protrusions 12.

[0028] Further, in order to facilitate the two protrusions 12 to enter the card slot 8, refer to Figure 4 As shown, the end of the fastener 6 is also provided with an opening 10 connected to the slot 8, and the opening 10 is in an expanded state from the inside to the outside. When the two protrusions 12 are in the groove 5, the end of the fastener 6 close to the slot 8 is placed in the groove 5, and pressure is applied to the fastener 6 at this time. The two protrusions 12 are in the opening 10. Under continuous pressure, the two protrusions 12 automatically approach each other in the opening 10. When the two protrusions 12 break through the connection between the opening 10 and the slot 8, the two protrusions 12 automatically open in the slot 8, thereby locking the fastener 6 on the two protrusions 12 to prevent the fastener 6 from being separated.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
