Description

Technical Field

[0001] The utility model relates to the technical field of nameplates, and in particular to a nameplate component of an easily replaceable waterproof access control host and an access control host. Background Art

[0002] Since villas or houses are basically single households using one access control host, in order to facilitate visitors to clearly know the situation of the residents, a nameplate will be set on the access control host, which can be used to write relevant information of the residents.

[0003] Since the environment of the access control host is often bad, it often rains, and the nameplate is easy to get water or water vapor, which causes the information written on the nameplate to fade easily and the transparent cover to fog up, making it difficult for visitors to identify the nameplate information written by the resident. On the other hand, for rented residences, the nameplate information often needs to be updated after the tenant is changed. Some nameplates use snap-on connections, but after the snap-on connection is closed, it is basically difficult to remove it to modify the resident information, and it is difficult to operate when updating the nameplate information; some nameplates are provided with a handle on the exterior surface for easy removal, but the handle position affects the appearance on the one hand, and it is easy to be maliciously modified or taken away on the other hand. The existence of the handle position results in no sealing protection for the nameplate, and water vapor will enter the nameplate to accelerate the fading and aging of the font on the nameplate. It is easy to fog up the nameplate lens on rainy days, and water and dust will also enter the inside of the access control host from the gap between the nameplate and the front cover.

Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0027] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0028] It includes a front cover 1, a transparent pressure cover 2 and a bracket 3. The front cover 1 is provided with a hollow portion 10, and the bracket 3 is fixedly provided behind the hollow portion 10. The transparent pressure cover 2 is sealed and embedded in the hollow portion 10 from front to back, and a nameplate 5 is sandwiched between the transparent pressure cover 2 and the bracket 3.

[0029] Reference Figures 1 to 5As shown, a nameplate assembly of an easily replaceable waterproof access control host comprises a front cover 1, a transparent pressure cover 2 and a bracket 3. The nameplate 5 is sandwiched between the transparent pressure cover 2 and the bracket 3. The front cover 1 is provided with a hollow portion 10, and a bracket 3 is fixedly provided behind the hollow portion 10, and also comprises at least one top member 4, and an installation chamber 36 is formed between the transparent pressure cover 2 and the bracket 3, and the top member 4 can be rotatably arranged in the installation chamber 36, and one end of the top member 4 is provided with a pressure-bearing end 43, and the other end is provided with a lifting end 42, and the lifting end 42 abuts against the transparent pressure cover 2; the front cover 1 is provided with a pinhole 11, and the pinhole 11 is connected to the installation chamber 36, and the pressure-bearing end 43 abuts and seals against the rear end of the pinhole 11.

[0030] It also includes a ejector pin 6, which can be a toothpick or a mobile phone card remover or a button. The ejector pin 6 is inserted into the pinhole 11 and drives the ejector 4 to rotate, so that the ejector end 42 of the ejector 4 clamped between the transparent pressure cover 2 and the bracket 3 rotates upward and drives the transparent pressure cover 2 to separate from the bracket 3 and the front cover 1.

[0031] refer to Figure 2 and Figure 5 As shown, the bracket 3 includes a panel 31, a mounting platform 32 is formed at the upper end of the panel 31, the upper end of the mounting platform 32 is recessed downward to form a positioning groove 33 for installing and positioning the nameplate 5, and an annular slot 34 is provided between the bracket 3 and the front cover 1 for the transparent pressure cover 2 to be inserted.

[0032] The upper end of the panel 31 is recessed downward to form a clearance groove 36, which is located on both sides of the mounting platform 32. The two sides of the clearance groove 36 extend upward to form two connecting seats 37. The top piece 4 is arranged in the clearance groove 36. The top piece 4 includes a rotating shaft 41 and a lifting end 42 and a pressure end 43 located on the left and right sides. The top piece 4 is rotatably connected to the connecting seat 37 through the rotating shaft 41. The lifting end 42 is clamped between the transparent pressure cover 2 and the bracket 3, and the pressure end 43 is located at the lower end of the pinhole 11.

[0033] Specifically, the connection seat 37 is provided with a mounting hole, the rotating shaft 41 is embedded in the mounting hole, and the upper surface of the connection seat 37 is formed with a guiding inclined surface 371 for guiding the rotating shaft 41 to embed into the mounting hole. During assembly, the rotating shaft 41 of the top member 4 is pressed into the mounting hole, so that the top member 4 can rotate on the bracket 3 at a certain angle.

[0034] In order to prevent the transparent gland 2 from tilting and getting stuck due to unbalanced force, top pieces 4 are provided on both sides of the nameplate 5 . There are two top pieces 4 symmetrically arranged on both sides of the transparent gland 2 .

[0035] The top member 4 is fixed with an elastic pad 44, which blocks the pinhole 11. The elastic pad 44 can be made of elastic materials such as foam or silica gel, and the elastic pad 44 blocks the pinhole 11, thereby preventing external rain or water vapor from penetrating into the nameplate 5.

[0036] The sealing gasket 7 is also included. The sealing gasket 7 is sandwiched between the front cover 1 and the bracket 3. The front cover 1 and the bracket 3 are connected by screws. The bracket 3 and the front cover 1 isolate and seal the structure between the nameplate 5 and the inside of the access control host through the sealing gasket 7. The sealing gasket 7 plays a role in waterproofing and dustproofing. Figure 3 and Figure 4 As shown, a positioning protrusion 12 is provided on the back of the front cover 1, and a buckling portion 71 is formed on the periphery of the sealing gasket 7, which protrudes upward and fits around the outer periphery of the positioning protrusion 12. The above structure improves the waterproof and dustproof effects.

[0037] The upper end of the front cover 1 is fixed with a decorative panel 9. The decorative panel 9 is used as a decorative surface of the access control host. The access control host also includes a rear cover and a circuit board and other structures. The circuit board and other component structures of the access control host are hidden between the front cover 1 and the rear cover.

[0038] The outer periphery of the transparent gland 2 is provided with a sealing ring 8 located between the front cover 1 and the transparent gland 2. A groove 21 is provided on the peripheral side wall of the transparent gland 2. The sealing ring 8 is made of silicone material, and the sealing ring 8 is inserted into the groove 21 by utilizing the elasticity of silicone. The sealing ring 8 is formed with two arc-shaped protrusions 81 on the side facing the transparent gland 2. The protrusions 81 and the side wall surface of the front cover 1 form a certain interference fit. The two protrusions 81 can not only play the role of double-layer waterproof and dustproof, but also play the role of fixing the transparent cover of the nameplate 5 due to the interference fit. Since the matching clearance between the transparent gland 2 and the decorative panel 9 and the front cover 1 is relatively small, the possibility of the nameplate 5 being easily removed or maliciously modified is avoided.

[0039] When in use, by inserting a sharp needle-like object such as a thimble 6 or a toothpick from the pinhole 11, the needle-like object will drive the pressure-receiving end 43 to move downward, and the downward movement of the pressure-receiving end 43 will drive the lifting end 42 to move upward, and the upward movement of the lifting end 42 will drive the transparent pressure cover 2 to separate from the bracket 3 and the front cover 1. In this way, the nameplate 5 assembly can be quickly and easily disassembled, and the problem that the nameplate 5 is difficult to remove to modify the resident information or can be easily removed and maliciously modified is solved. In addition, there are only small pinholes 11 on the appearance surface, which better ensures the appearance effect of the product.

[0040] During assembly, after the bracket 3 and the front cover 1 are fastened by screws, the nameplate 5 is placed in the positioning groove 33 of the bracket 3, and then the transparent pressure cover 2 is inserted into the annular slot 34 between the bracket 3 and the front cover 1. The transparent pressure cover 2 will press the lifting end 42 of the ejector pin 6, and the downward movement of the lifting end 42 will drive the pressed end 43 to move upward, so that the elastic pad 44 blocks the pinhole 11.

[0041] The advantages of the utility model are: 1. By using a tool such as a thimble 6 to take out the nameplate 5, only two tiny pinholes 11 need to be opened on the exterior surface, thereby ensuring a better appearance effect; 2. The problem that the transparent pressure cover 2 and the nameplate 5 are difficult to be taken out to modify the resident information or can be easily taken out and maliciously modified is solved; 3. Through the sealing cooperation between the transparent pressure cover 2, the decorative panel 9 and the front cover 1, rain or water vapor can be prevented from entering the nameplate 5 position, resulting in accelerated aging of the information on the nameplate 5 or fogging of the transparent pressure cover 2.

[0042] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
