[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are 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. 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.

[0028] 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.

[0029] An ultra-thin access control host comprises a host body 1, wherein the host body 1 comprises a panel 11 and a rear shell 12, and a main board 13 is arranged between the panel 11 and the rear shell 12. Figure 1 and Figure 2As shown, the mainboard 13 is provided with a centralized area 131. The mainboard 13 includes components such as a power connector 132, a network port seat 133, and a relay 134 to work properly. Since the size specifications of electronic components such as the power connector 132, the network port seat 133, and the relay 134 are relatively large, they are collectively referred to as high components. The high components are centralized in the centralized area 131 of the mainboard 13, and then the rear shell 12 is provided with a flange 121 arranged around the centralized area 131, and the flange 121 is provided with a wiring port 1221. The space formed by the flange 121 of the rear shell 12 accommodates the high components of the mainboard 13, and then the cover plate 2 is covered on the opening formed by the flange 121, so that the high components are hidden in the rear shell 12, and the mainboard 13 is protected.

[0030] It also includes a junction box, which is pre-buried in the wall. The flange 121 will be buried in the junction box during installation, so that the thickness of the access control host exposed outside the wall becomes thinner, is not restricted by the high device of the main board 13, and enhances the aesthetics of the product.

[0031] like Figure 1 and Figure 3 As shown, the cover plate 2 includes a plurality of insert plate portions 21 and snap plate portions 22 arranged on both sides thereof, and the flange 121 is provided with an insert hole 1222 snapped with the insert plate portion 21 , and a snap hole 1223 snapped with the snap plate portion 22 .

[0032] The cover plate 2 adopts the above structure, which can save the use of screws and reduce the assembly process. Compared with the previous cover plate method using a locking screw structure, it is difficult to install the cover plate 2 in the project installation, and the screws must be removed when the cover plate 2 is removed for maintenance. The operation is cumbersome. When installing the cover plate 2 of the utility model, one end only needs to be inserted into the insertion hole 1222 of the rear shell 12, and the other end is pressed into the buckle hole 1223 of the rear shell 12 to form a buckle of the cover plate 2. When disassembling, it is only necessary to insert a tool such as a screwdriver into the buckle hole 1223 to force the buckle plate to deform and then remove the cover plate 2. The cover plate 2 adopts a structure of single-sided insertion and one-side buckle, which is convenient for engineering personnel to operate and improve efficiency during installation; it is also easy to remove during disassembly and maintenance.

[0033] A sealing sheet 3 is fixedly disposed on the side of the cover plate 2 facing the high device. The sealing sheet 3 can be made of foam sponge, and the sealing sheet 3 is attached to the cover plate 2 to form a seal on the end surface of the wiring port 1221 of the rear shell 12.

[0034] The flange 121 is provided with a wiring port 1221, and a sealing block 4 is provided at the position of the wiring port 1221. The sealing block 4 can be made of foam sponge, and the sealing sheet 3 is attached to the cover plate 2, so as to form a seal on the end face of the wiring port 1221 of the rear shell 12. The sealing block 4 is attached to the wiring port 1221 and is partially squeezed by the cover plate 2. When a wire passes through the wiring port 1221, the sealing block 4 forms a certain wrapping around the wire, so that the wiring opening is as small as possible, thereby achieving the effect of waterproofing and dustproofing.

[0035] like Figures 4 to 6 As shown, when the host body 1 is installed in an external mounting style, it also includes an external mounting box 5, and the rear shell 12 is hidden in the external mounting box 5. In this embodiment, the junction box is an 86 box 6, and the external mounting box 5 is fixed to the 86 box 6. At this time, the outer dimensions of the flange 121 can just fit into the regional space formed by the 86 box 6, so that the thickness of the host body 1 exposed on the wall becomes thinner, and is not restricted by the high components on the main board 13, and the opening of the flange 121 is sunk into the 86 box 6, which can play a better waterproof and dustproof role for the wiring port 1221.

[0036] The external box 5 can prevent water or dust from rushing directly to the wiring port 1221, thus providing better protection for the wiring port 1221. On the other hand, the external box 5 wraps the entire rear shell 12, thus preventing the product from being divided into multiple layers in appearance. The exposed part on the wall only has the external box 5 and the panel 11 structure, and the product has a better overall appearance from the side view.

[0037] Specifically, the external box 5 is connected to the 86 box 6 by a plurality of first screws 51, and the rear shell 12 is provided with a first recessed portion 122 for accommodating the head structure of the first screws 51. The first recessed portion 122 minimizes the gap between the rear shell 12 and the external box 5.

[0038] Similarly, the external box 5 extends out of the wall surface of the wall, and the external box 5 is fixed to the wall by a plurality of second screws 52. The second screws 52 enhance the firmness of the connection between the external box 5 and the wall, and the rear shell 12 is provided with a second recessed portion 123 for accommodating the head structure of the second screws 52. The gap between the rear shell 12 and the external box 5 is minimized by the second recessed portion.

[0039] The external box 5 is fitted with a sealing pad on one side facing the wall, and the sealing pad is preferably made of rubber material. By attaching a sealing pad on the back of the external box 5, a seal is formed between the external box 5 and the wall surface after installation to prevent water from flowing along the wall to the wiring port 1221.

[0040] like Figure 7As shown, when the host body 1 is embedded, in this embodiment, the junction box is an embedded box 7, the rear shell 12 is hidden in the embedded box 7, and a wiring space 71 is formed between the rear shell 12 and the embedded box 7. When this method is adopted, the height of the embedded box 7 can be reduced, reducing the material cost; further, the depth of the groove on the wall can be reduced, reducing the on-site installation time, construction cost, etc.

[0041] 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.
