DETAILED DESCRIPTION

[0023] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation mode of the utility model will be described with reference to the drawings.

[0024] Example 1

[0025] The preferred embodiment of the double-body protective box fastening device provided by the utility model is as shown in the figure: Figures 1 to 6 A double-body protective box fastening device is provided, which comprises a box cover 1;

[0026] The outer wall of the box cover 1 is fixedly provided with a mounting plate 2;

[0027] A base plate 3 is arranged below the mounting plate 2;

[0028] A processing assembly 4 is arranged above the base plate 3, and the processing assembly 4 comprises a sealing assembly 41 arranged above the base plate 3. The sealing assembly 41 comprises a U-shaped pipe 411 arranged in communication with the inside of the mounting plate 2. The end of the U-shaped pipe 411 is arranged in communication with a sealing ring 412. The inner wall of the U-shaped pipe 411 is fixedly provided with a fixing ring 413. The side wall of the fixing ring 413 is fixedly provided with a spring 414. The end of the spring 414 away from the fixing ring 413 is fixedly provided with a sealing ring 415. The side of the sealing ring 415 away from the spring 414 is fixedly provided with a sliding rod 416. The end of the sliding rod 416 away from the sealing ring 415 is fixedly provided with a rubber pad 417.

[0029] In the embodiment, when the box cover 1 needs to be mounted on the base plate 3, the box cover 1 is placed above the base plate 3. The mounting block 421 fixedly arranged on the outer wall of the mounting plate 2 is aligned with the mounting hole arranged on the outer wall of the base plate 3. The mounting block 421 is mounted by the screw rod 422. When the rubber pad 417 fixedly arranged on the end of the sliding rod 416 arranged in sliding communication in the mounting plate 2 is in contact with the base plate 3, the rubber pad 417 is extruded. The rubber pad 417 drives the sliding rod 416 to slide into the U-shaped pipe 411. The outer wall of the sealing ring 415 fixedly arranged on the end of the sliding rod 416 is in sliding communication with the inner wall of the U-shaped pipe 411. Since the sealing ring 415 and the inner wall of the U-shaped pipe 411 are in sealed sliding communication, the sealing ring 415 pushes the gas in the U-shaped pipe 411 under the limitation of the sealing ring 415. The sealing ring 412 arranged in communication with the end of the U-shaped pipe 411 is inflated. The sealing ring 412 fills the gap between the box cover 1, the mounting plate 2 and the base plate 3. Under the limitation of the inflated sealing ring 412, the sealing effect of the box cover 1 and the base plate 3 is better. The box cover 1 is prevented from being damaged due to water entering the box cover 1. When the box cover 1 and the base plate 3 are dismounted, the rubber pad 417 is no longer extruded in contact with the base plate 3. Under the elastic action of the spring 414, the spring 414 drives the sealing ring 415 to move outward from the U-shaped pipe 411. The sealing ring 415 drives the gas in the U-shaped pipe 411 to be exhausted. The sliding rod 416 and the rubber pad 417 move outward from the U-shaped pipe 411. The rubber pad 417 and the sliding rod 416 are reset, so that the sealing ring 412 is inflated and expanded next time.

[0030] Further, the rubber pad 417 is made of rubber material. The sealing ring 415 and the U-shaped pipe 411 are in sealed sliding communication. Under the limitation of the rubber material of the rubber pad 417, the box cover 1 is prevented from sliding on the top surface of the base plate 3. The alignment of the box cover 1 and the base plate 3 is more accurate. Since the sealing ring 415 and the U-shaped pipe 411 are in sealed sliding communication, the sealing ring 415 pushes and exhausts the gas in the U-shaped pipe 411, so as to inflate and deflate the sealing ring 412.

[0031] Furthermore, the sealing ring 412 is made of rubber and has toughness. Under the constraint of the rubber sealing ring 412, the sliding sealing ring 415 can inflate the sealing ring 412. The toughness of the sealing ring 412 can extend its service life and improve the sealing effect between the lid 1 and the base plate 3.

[0032] Example 2

[0033] Based on Embodiment 1, a preferred embodiment of the double-body protective box fastening device provided by this utility model is, for example... Figures 1 to 6 As shown: The protective component 42 includes a mounting block 421 fixedly installed on the outer wall of the mounting plate 2. A screw 422 is sleeved inside the mounting block 421. A first magnetic ring 423 is fixedly installed on the outer wall of the screw 422. A sleeve 424 is sleeved outside the screw 422. A second magnetic ring 425 is fixedly installed on the inner wall of the sleeve 424. A retaining pad 426 is sleeved at the end of the sleeve 424.

[0034] In this embodiment, when it is necessary to install the cover 1 and the base plate 3, the mounting block 421 fixedly installed on the outer wall of the mounting plate 2 is aligned with the mounting hole opened on the outer wall of the base plate 3, and then installed by the screw 422. Since the sleeve 424 is fitted with the screw 422, and the second magnetic ring 425 and the first magnetic ring 423 are magnetically repelled, under its restriction, when the screw 422 moves into the base plate 3, it can make the first magnetic ring 423 move towards the second magnetic ring 425 set inside the sleeve 424. Due to the magnetic repulsion, the first magnetic ring 423 pushes the second magnetic ring 425 towards the base plate 3, so that the sleeve 424 contacts the top surface of the base plate 3. Then, the retaining pad 426 is pressed and fitted onto the end of the sleeve 424. Under the restriction of the sleeve 424 and the retaining pad 426, the screw 422 can be protected to prevent rainwater from causing the screw 422 to rust. This structure can prevent the screw 422 from rusting, making it easier to assemble and disassemble the cover 1 and the base plate 3.

[0035] Furthermore, the gasket 426 is made of rubber, and the end of the sleeve 424 away from the gasket 426 is also made of rubber. Under its constraint, the screw 422 can be wrapped to prevent it from rusting.

[0036] In addition, the screw 422 is threaded onto the base plate 3, and the screw 422 is rotatably connected to the sleeve 424. The sleeve 424 is slidably disposed on the outer wall of the screw 422. Under the protection of the sleeve 424, the screw 422 can be prevented from rusting due to rainwater.

[0037] The above is only a specific embodiment of the present application, and is not used to limit the scope of the present application. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present application shall belong to the scope of protection of the present application. Moreover, it should be noted that the components of the present application are not limited to the above overall application, and the technical features described in the specification of the present application can be selected for single use or combined use according to actual needs, therefore, the present application naturally covers other combinations and specific applications related to the present application.
