[0006] A baffle plate vertically arranged and mounted on an open side of the box body, wherein the baffle plate is arranged at a laser port of the sensor to form a first opening-shaped structure for facilitating the passage of laser light;

[0007] A pressing plate vertically arranged and mounted on the baffle, wherein the pressing plate and the baffle form a hollow cavity, a side of the hollow cavity has an open first mounting surface, and a through second opening-shaped structure is arranged at a position opposite to the first opening-shaped structure of the pressing plate;

[0008] A light-transmitting body is inserted into the hollow cavity from the first mounting surface, and the light-transmitting body is clamped between the first opening-shaped structure and the second opening-shaped structure.

[0009] As a further improvement of the utility model, it also includes a cover plate, which is movably connected to the box body and is used to close the first installation surface.

[0010] As a further improvement of the present invention, the box body is provided with a second mounting surface located in the same plane as the first mounting surface, and the cover plate is used to close the first mounting surface and the second mounting surface.

[0011] As a further improvement of the present invention, the light-transmitting body is glass.

[0012] As a further improvement of the present invention, the cover plate and the box body are fixed by bolts.

[0013] The beneficial effect of the utility model is that, in the utility model, the sensor is placed in the box body, and a light-transmitting body is inserted into the hollow cavity of the pressure plate and the baffle. The sensor can emit or receive light through the light-transmitting body, which can effectively protect the sensor and ensure that the sensor functions normally. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural schematic diagram of the utility model.

[0015] In the figure: 2-box body; 4-baffle; 6-pressing plate; 8-light-transmitting body; 10-cover plate. DETAILED DESCRIPTION

[0016] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0017] like Figure 1 As shown, the utility model includes:

[0018] A box body 2, wherein the box body 2 is a hollow structure and is used to place the sensor therein, and the box body 2 has at least one open side;

[0019] A baffle plate 4 is vertically arranged and mounted on an open side of the box body 2, wherein the baffle plate 4 is arranged at a laser port of the sensor to form a first opening-shaped structure for facilitating the laser to pass through;

[0020] A pressing plate 6 vertically arranged and mounted on the baffle 4, wherein the pressing plate 6 and the baffle 4 form a hollow cavity, the side of the hollow cavity has an open first mounting surface, and a through second opening-shaped structure is provided at a position of the pressing plate 6 opposite to the first opening-shaped structure;

[0021] The light-transmitting body 8 is inserted into the hollow cavity from the first mounting surface, and the light-transmitting body 8 is clamped between the first opening-shaped structure and the second opening-shaped structure.

[0022] In the utility model, the sensor is placed in the box body 2, and the light-transmitting body 8 is inserted into the hollow cavity of the pressure plate 6 and the baffle 4. The sensor can emit or receive light through the light-transmitting body 8, which can effectively protect the sensor and ensure that the sensor functions normally.

[0023] As a further improvement of the utility model, it further comprises a cover plate 10, wherein the cover plate 10 is movably connected to the box body 2 and is used to close the first installation surface.
