Description

Technical Field

[0001] The utility model relates to the technical field of access control visual intercoms, in particular to a dust-proof structure for an access control visual intercom. Background Art

[0002] When installing an access control visual intercom in an outdoor place, the dust-proof structure can effectively prevent sundries such as dust and sand from entering the device, ensuring the normal operation and long-term stability of the device. When installing an access control visual intercom at a construction site or other construction sites, the dust-proof structure can prevent substances such as dust and mud generated during construction from damaging the device, extending the service life of the device. When installing an access control visual intercom in a highly polluted environment such as a factory or workshop, the dust-proof structure can reduce the erosion of dust, chemical substances, etc. on the device, ensuring the long-term stable operation of the device.

[0003] For the existing dust-proof structure of a visual intercom, the generally set dust-proof structure is of a fixed design. When it is necessary to adjust the angle of the intercom for more suitable visual communication, the dust-proof structure and the intercom cannot be adjusted simultaneously, resulting in poor applicability. In addition, in order to prevent dust and pollutants from falling on the device, the generally set dust-proof cover is of a closed and opaque design, and it is also necessary to open the dust-proof cover for visual communication, which is rather inconvenient. Content of the Utility Model

[0004] (1) Technical Problems to be Solved

[0005] The technical problem to be solved by the utility model is that the dust-proof structure and the intercom cannot be adjusted simultaneously, resulting in poor applicability, and the dust-proof cover is not designed as a transparent structure for visualization, and it is still necessary to open it for visual communication, causing inconvenience.

[0006] (2) Technical Solutions

[0007] To solve the above technical problems, the technical solution provided by the utility model is as follows:

[0008] A dust-proof structure for an access control visual intercom, comprising an intercom base, an intercom body provided on the upper side of the intercom base, a camera provided on the front side of the intercom body, a display screen provided below the camera, and further comprising a connecting plate, a rotating column, a rotating positioning mechanism, a docking plate, a dust-proof frame, a docking rod, and an observation panel;

[0011] As an improvement, the rotation positioning mechanism includes a fixing screw one, a fixing screw two, an arc-shaped buckle, and a torsion spring. An arc-shaped buckle that fits with the rotating column is provided in the rotating slot. The fixing screw one passes through the slot reserved on the arc-shaped buckle and is fixed on the connecting plate. The fixing screw two fixed on the connecting plate is provided below the fixing screw one. A torsion spring sleeved on the fixing screw two is provided below the arc-shaped buckle, and the movable ends of the torsion spring are respectively placed on the rear side surface of the arc-shaped buckle and the connecting plate.

[0012] As an improvement, the rotating slot extends through to the rear side surface of the connecting plate, and a fixing slot for fixing the arc-shaped buckle and the torsion spring is provided in the rotating slot.

[0013] As an improvement, when the rear side surface of the dust-proof frame is attached to the front side surface of the intercom body, the bottom end of the dust-proof frame completely covers the screen inside.

[0014] As an improvement, both the left and right sides at the top end of the dust-proof frame are arc-shaped structures and are slidably connected to the front side surface of the intercom body.

[0027] The following further describes the present utility model in detail with reference to the drawings

[0028] Please refer to the attached Figure 1 attachment Figure 4 attachment Figure 7As shown in the figure, a dust-proof structure of an access control visual intercom includes an intercom base 1. There is an intercom body 2 on the upper side of the intercom base 1. There is a camera 3 on the front side of the intercom body 2, and a display screen 4 is provided below the camera 3. On the left and right sides of the top end of the intercom base 1, there are connecting plates 5 respectively. Rotating grooves 11 are reserved at the tops of the opposite sides of the connecting plates 5. At the left and right ends of the intercom body 2, there are rotating columns 6 which are rotatably connected with the rotating grooves 11 in a matching manner. An arc-shaped buckle 14 which fits with the rotating column 6 is arranged in the rotating groove 11. The rotating groove 11 extends through to the rear side of the connecting plate 5, and a fixing groove for fixing the arc-shaped buckle 14 and a torsion spring 15 is arranged in the rotating groove 11. A fixing screw 12 passes through the notch reserved on the arc-shaped buckle 14 and is fixed on the connecting plate 5. Below the fixing screw 12, there is a fixing screw 13 fixed on the connecting plate 5. A torsion spring 15 sleeved on the fixing screw 13 is arranged below the arc-shaped buckle 14. The movable ends of the torsion spring 15 are respectively placed on the rear side of the arc-shaped buckle 14 and the connecting plate 5.

[0029] Please refer to the attached Figure 2 attachment Figure 3 attachment Figure 5 and attachment Figure 6 As shown in the figure, a docking plate 7 fixed on the front side of the intercom body 2 is arranged above the camera 3. Docking grooves are reserved at the left and right ends of the docking plate 7. The dust-proof frame 8 is a concave structure with an opening at the upper part, and the left and right sides of the top end are both arc-shaped structures, and it is slidably connected with the front side of the intercom body 2. Docking rods 9 which are rotatably connected with the docking grooves in a matching manner are arranged on the opposite sides of the top of the dust-proof frame 8. The rear side of the dust-proof frame 8 can be attached to the front side of the intercom body 2, and a transparent observation panel 10 is arranged on the front side. When the rear side of the dust-proof frame 8 is attached to the front side of the intercom body 2, the bottom end of the dust-proof frame 8 completely covers the screen inside.

[0030] Through the above structure, under the action of the torsion spring 15, the arc-shaped buckle 14 clamps and fixes the intercom body 2 through friction. By rotating the dust-proof frame 8, the camera 3 and the display screen 4 can be surrounded, effectively preventing dust from falling on them and keeping them clean. Visual communication can be carried out through the transparent observation panel 10.

[0031] In the specific implementation of the present utility model: when it is necessary to adjust the angle of the walkie-talkie for face visual intercom, pull the arc-shaped buckle 14 to separate it from the rotating column 6. After rotating the walkie-talkie body 2 to a suitable position, release the arc-shaped buckle 14. Under the action of the torsion spring 15, the arc-shaped buckle 14 clamps and fixes the walkie-talkie body 2 through friction. When it is necessary to dust-proof the walkie-talkie body 2, since the docking rods 9 provided on the top and opposite sides of the dust-proof frame 8 are rotatably connected with the docking grooves at the left and right ends of the docking plate 7, the dust-proof frame 8 can be rotated so that the rear side of the dust-proof frame 8 fits with the front side of the walkie-talkie body 2, surrounding the camera 3 and the display screen 4, effectively preventing dust from falling on them and keeping them clean. Visual communication can be carried out through the transparent observation panel 10.

[0032] The above describes the present utility model and its implementation manners. Such a description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the creative purpose of the present utility model, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
