Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-7, the present invention provides an embodiment: the utility model provides a take dustproof construction's charger, includes charger main part 1, lug 2 and shield 3, and the top of charger main part 1 is fixed with

lug

2, and 2 tight joint have shield 3 on the lug, and 1 surface glue of charger main part has protector 4, and protector 4's back bottom mounting has standing groove 5, can place shield 3 through standing groove 5, avoids shield 3 to be put everywhere by people and leads to losing.

First magnet piece caulking groove 9 has been seted up to standing groove 5's inside bottom symmetry, and first magnet piece caulking groove 9 is inside all to inlay and be equipped with first magnet piece 7, second magnet piece caulking groove 10 has all been seted up to the left and right sides on shield 3 top, and second magnet piece caulking groove 10 is inside all to inlay and be equipped with the second magnet piece 8 of mutually supporting with first magnet piece 7, through mutually supporting of first magnet piece 7 and second magnet piece 8, can fix shield 3 and standing groove 5, make shield 3 can be more firm place inside standing groove 5.

Protector 4 and standing groove 5 formula structure as an organic whole, make protector 4 and standing groove 5 structure inseparable and reasonable, the length of 5 inner walls of standing groove equals the length of 3 outer walls of shield, the width of 5 inner walls of standing groove equals the width of 3 outer walls of shield, through the design of length and width, make shield 3 can be fine the block advance inside 5 standing grooves, the effect of the first magnet piece 7 of arranging again and second magnet piece 8, further make

shield

3 and 5 firm in connection of standing groove, the practicality and the convenience of device have been improved.

The protection device 4 comprises a cushion 41, a cavity 42, a hard plate 43, a first rubber hemisphere 44, a second rubber hemisphere 45 and a spring 46, wherein the cushion 41 is adhered to the periphery of the outer surface of the charger main body 1, the front surface and the back surface of the cushion 41 are both adhered with first frosted stickers 6, through the design of the first frosted stickers 6, when people use the charger main body 1, the hands of people are in contact with the first frosted stickers 6, the friction force between the hands and the first frosted stickers 6 is increased, people can stably hold the charger and are not easy to slip, the second frosted stickers 11 are adhered to two sides of the bottom end of the cushion 41, through the design of the cushion 41, when the charger main body 1 is used, the cushion 41 is in contact with the wall surface in a fit mode, the friction force is slightly increased, then under the effect of the placement groove 5, the height of the bottom is increased, and then the friction force between the cushion 41 and the wall surface is further increased, and then the placing groove 5 is fully abutted against the wall surface, so that the charger main body 1 cannot easily fall off, the device is indirectly protected, and the protection performance of the device is further improved.

The cavity 42 is formed in the cushion 41, hard plates 43 are glued on the inner walls of the front end and the rear end of the cavity 42, first rubber hemispheres 44 are glued on the two sides of the back surface of the front end hard plate 43, second rubber hemispheres 45 matched with the first rubber hemispheres 44 are glued on the two ends of the front surface of the rear end hard plate 43, a spring 46 is arranged between the two second rubber hemispheres 45, one end of the spring 46 is welded with the front end hard plate 43, the other end of the spring 46 is welded with the rear end hard plate 43, the spring 46 is firmly connected with the hard plate 43 through a welding mode, the structure is reasonable, when the charger main body 1 drops on the ground carelessly, the cushion 41 can be extruded, the cushion 41 is soft, rigid collision can be avoided, after the cushion 41 is extruded, the hard plates 43 in the cushion 41 are extruded mutually, so that the first rubber hemispheres 44, the second rubber hemispheres 45 and the spring 46 are compressed, make first rubber hemisphere 44, second rubber hemisphere 45 and spring 46 possess the restoring force, realize the buffering to charger main part 1, protect it to a certain extent, avoid charger main part 1 direct and ground contact to lead to charger main part 1 to produce the condition emergence of crack or even damage because of the rigidity collision, improved the practicality of device, prolonged the life of device simultaneously, need not purchase relevant charger again, the indirect input cost that has saved.

The working principle is as follows: firstly, when the charger main body 1 is used, as shown in attached figures 1, 2, 3, 4 and 5, firstly, one hand holds the first frosted patch 6 on the surface of the protection device 4, the other hand pulls the dust cover 3 upwards, the dust cover 3 is inverted after the dust cover 3 is separated from the bump 2 in a clamping state, then the dust cover 3 is inserted into the placing groove 5, and at the moment, the second magnet block 8 at the bottom of the dust cover 3 and the first magnet block 7 at the bottom end in the placing groove 5 are mutually adsorbed together, so that the dust cover 3 is stored;

when the charger main body 1 is accidentally dropped on the ground, as shown in fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, fig. 6 and fig. 7, after the charger main body 1 is dropped on the ground, the cushion 41 is in contact with the ground and collides with the ground, the cushion 41 is pressed, the hard plate 43 inside the cavity 42 is pressed after the cushion 41 is pressed, and after the two hard plates 43 are pressed with each other, the first rubber hemisphere 44, the second rubber hemisphere 45 and the spring 46 are correspondingly pressed, so that the first rubber hemisphere 44, the second rubber hemisphere 45 and the spring 46 are compressed to generate restoring force until the charger main body 1 stops moving, and the cushion 41 and the hard plate 43 return to the original positions under the restoring force of the first rubber hemisphere 44, the second rubber hemisphere 45 and the spring 46;

when the charger main body 1 needs to be inserted into the socket, as can be seen from fig. 1, fig. 2, fig. 3, fig. 4, fig. 5 and fig. 6, when the charger main body 1 is completely attached to the socket, the soft pad 41 on the protection device 4 will be fully attached to the wall surface, and the second frosted paste 11 on the soft pad 41 will be fully contacted with the wall surface, because the wall surface generally has small white bumps, the friction force contacting with the wall surface can be increased, and meanwhile, after the thickness of the bottom of the charger main body 1 is increased through the placement groove 5, the device is further abutted to the wall surface, and the operation is finished.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
