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.

[0024] 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.

[0025] Reference Figures 3 to 7 As shown, a convenient and adjustable embedded box includes an embedded box body 1, a first drawer 2 and a second drawer 4. The front end of the embedded box body 1 is an open surface, which is exposed to the wall and is used to install the mounting surface of the access control host 7. One end of the first drawer 2 and the second drawer 4 are respectively arranged at the upper and lower ends of the embedded box body 1 in a forward and backward adjustable manner, and the other ends of the first drawer 2 and the second drawer 4 are used to connect the access control host 7.

[0026] Reference Figures 3 to 7 As shown, the embedded box body 1 includes a bottom plate 14, and an upper enclosure plate 11, a lower enclosure plate 12, and two side plates 13 connecting the upper enclosure plate 11 and the lower enclosure plate 12 are arranged on the outer periphery of the bottom plate 14. The upper ends of the inner walls of the two side plates 13 are fixed with first guide plates 15, and the two first guide plates 15 are arranged parallel to the upper enclosure plate 11 and constitute a first guide groove for sliding the first drawer 2. The first drawer 2 includes a first panel 21, and the left and right sides of the first panel 21 are fixed with first abutment plates 22, the first abutment plates 22 abut against the first guide plates 15, and the first panel 21 abuts against the upper enclosure plate 11, thereby ensuring that the first drawer 2 slides smoothly and stably in the embedded box body 1.

[0027] The first guide plate 15 is provided with a first adjustment hole 151, which is a strip-shaped hole extending forward and backward. The first fastener 3 passes through the first adjustment hole 151 and is threadedly connected to the first drawer 2, thereby locking the first drawer 2. The above structure realizes that the first drawer 2 and the embedded box body 1 can be adjusted forward and backward.

[0028] The first fastener 3 passes through the first adjustment hole 151 and is connected to the first drawer 2. The first fastener 3 is preferably a screw, and the first abutment plate 22 is provided with a thread matching the screw. The above structure enables the first drawer 2 to be adjusted in height on the embedded box body 1.

[0029] The first drawer 2 is extended upwardly to have a first folding plate 23 for contacting the rear end of the access control host 7. The first folding plate 23 increases the contact area between the first drawer 2 and the access control host 7, thereby reducing the pressure between the first drawer 2 and the access control host 7.

[0030] Similarly, the lower ends of the inner walls of the two side panels 13 are fixed with second guide plates 16, which are arranged in parallel with the lower enclosure 12 and form a second guide groove for the second drawer 4 to slide. The second drawer 4 includes a second panel 41, and the left and right sides of the second panel 41 are fixed with second abutment plates 42. The second abutment plates 42 abut against the second guide plates 16, and the second panel 41 abuts against the upper enclosure 11, thereby ensuring that the second drawer 4 slides smoothly and stably in the embedded box body 1.

[0031] The second guide plate 16 also includes a second fastener 5. The second guide plate 16 is provided with a second adjustment hole 161, which is a strip hole extending forward and backward. The second fastener 5 passes through the second adjustment hole 161 and is connected to the second drawer 4, thereby locking the second drawer 4. The above structure enables the second drawer 4 and the embedded box body 1 to be adjusted forward and backward.

[0032] The second drawer 4 is extended downwardly to be provided with a second folding plate 43, which is used to abut against the rear end of the access control host 7. The first folding plate 23 increases the contact area between the second drawer 4 and the access control host 7, thereby reducing the pressure between the second drawer 4 and the access control host 7.

[0033] The first guide plate 15 and the second guide plate 16 are both provided with scale lines 152 (for example, one scale line is provided at every 2 mm interval), and the first drawer 2 and the second drawer 4 are both provided with corresponding lines 211 for aligning the scale lines 152, and the corresponding lines 211 are respectively provided on the first panel 21 and the second panel 41. The scale lines 152 of the first guide plate 15 and the second guide plate 16 are arranged at the same height, and when the height of the first drawer 2 and the second drawer 4 is adjusted, the corresponding lines 211 of the first drawer 2 and the second drawer 4 are aligned with the same scale line 152, which indicates that the first drawer 2 and the second drawer 4 are arranged at the same height.

[0034] The first drawer 2 is fixed with a first connecting ear 24 extending to the outside of the embedded box body 1. The second drawer 4 is fixed with two second connecting ears 44 arranged at intervals extending to the outside of the embedded box body 1. The first connecting ear 24 and the second connecting ear 44 are used to be locked and connected to the access control host 7 by screws or the like.

[0035] The second drawer 4 is provided with an anti-separation support plate 45. The anti-separation support plate 45 is arranged in parallel with the bottom plate 14 of the embedded box body 1. The function of the anti-separation support plate 45 is as follows: in order to prevent the intelligent access control host device from being maliciously removed from the embedded box, an anti-separation support plate 45 is added to realize the anti-removal function. When the intelligent access control terminal device is maliciously removed, that is, the anti-separation support plate 45 is separated from the abutment provided by the access control host 7, the access control host 7 will issue an alarm and simultaneously upload the alarm information to the management platform. Specifically, the access control host 7 is provided with an anti-removal switch, and the anti-removal switch must rely on the support of the anti-separation support plate 45. If someone removes the access control host 7, an alarm will be issued. Therefore, the adjustable height of the second drawer 4 on the embedded body can ensure that the anti-separation support plate 45 can be adjusted to press against the anti-removal switch, and the anti-removal function will not fail due to the situation that the anti-separation support plate 45 of the traditional embedded box cannot fit the anti-removal switch.

[0036] The embedded box body 1, the first drawer 2 and the second drawer 4 can be formed at one time by a sheet metal stamping die.

[0037] When in use, the adjustable embedded box of the utility model meets the requirements of all wall-mounted access control host 7 (such as the wall is higher than the embedded box), and only the first fastener 3 and the second fastener 5 need to be loosened (but not removed), and then the first drawer 2 and the second drawer 4 are adjusted to the wall and the position required by the installer. Since the anti-detachment support plate 45 is arranged on the second drawer 4, it will also move at the same time, and then the first fastener 3 and the second fastener 5 are locked. Then the access control host 7 can be installed, and the anti-detachment switch of the access control host 7 also works.

[0038] The advantages of the utility model are: reducing the construction and modification costs required by the installers during installation; it can be manufactured using only a simple sheet metal stamping die; only simple assembly is required to achieve rapid installation of the adjustable embedded box product of the utility model; and it can solve the problem of matching the embedded box installation of the access control host 7 with different wall surfaces.

[0039] 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.
