Description

Technical Field

[0001] The utility model relates to the technical field of engineering measurement, in particular to a protective device for a reflective diaphragm in a hole. Background Art

[0002] In the relevant measurements of tunnel engineering construction, a total station is used in conjunction with a reflective diaphragm to achieve long-distance measurement.

[0003] Due to the large number of vehicles passing through the tunnel during construction, it is very easy for silt to splash onto the reflective film, causing the reflective film to be contaminated or damaged by collision with construction machinery. For example, the utility model patent with announcement number CN 202133400 U records a snap-on rulerless measuring reflective film protection device, which includes a box body, a box cover, a reflective film, a fixing nut and a measuring pull rod. The box body and the rear of the box cover are connected by a hinge, and a fixing nut is provided on the bottom surface of the box body. The fixing nut is connected and fixed with the embedded screw. The reflective film is attached to the middle position of the inner surface of the box body. It relies on the box body and the box cover to cover the reflective film (i.e., the reflective film), thereby protecting the reflective film. However, when the reflective film is used for measurement, the reflective film will also be contaminated, and the reflective film needs to be cleaned and replaced. There is a problem that cleaning and replacement are relatively inconvenient. For this reason, the utility model further provides a protection device for the reflective film in the tunnel. Utility Model Content

[0004] In order to solve the problem that the reflective sheet (i.e., reflective film) is inconvenient to clean and replace in the existing protective structure in which the box body and the box cover cover the reflective sheet, the utility model provides a protective device for the reflective film in the hole.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A protective device for a reflective membrane in a hole, comprising:

[0007] A protective bottom shell and a rotating shell, wherein the rotating shell is rotatably mounted on a side surface of the protective bottom shell, and the reflective film is arranged inside the protective bottom shell;

[0008] The reflective plate body has a reflective film attached to the side surface of the reflective plate body, and the reflective plate body is detachably installed inside the protective bottom shell.

[0009] As a further description of the above technical solution:

[0010] The inner bottom of the protective bottom shell is provided with a mounting hole, and a pad is fixedly provided on the side surface of the protective bottom shell at a position corresponding to the mounting hole.

[0011] As a further description of the above technical solution:

[0012] The top side of the protective bottom shell is bent upward to form an L-shaped folding plate, an L-shaped sliding hole is opened on the L-shaped folding plate, a T-shaped connector is slidingly provided inside the L-shaped sliding hole, a connecting head is rotatably installed on the top of the reflective plate body, and the connecting head is threadedly connected to the T-shaped connector.

[0013] As a further description of the above technical solution:

[0014] Both sides of the reflective plate body are provided with reflective films.

[0015] As a further description of the above technical solution:

[0016] A through hole is formed at a corner of the reflective plate body, and a buffer is installed inside the through hole;

[0017] The buffer member comprises:

[0018] A first conical shell, wherein a threaded female head is fixedly connected to an inner side of the first conical shell, and a first circular washer is fixedly connected to an outer end portion of the first conical shell;

[0019] The second conical shell is fixedly connected to a threaded male head on the inner side of the second conical shell, and a second round washer is fixedly connected to the outer end of the second conical shell, and the threaded male head is threadedly connected to the threaded female head.

[0020] As a further description of the above technical solution:

[0032] Please refer to the attached Figures 1-6 , shows a protective device for a reflective film in a hole provided by an embodiment of the present application, including: a protective bottom shell 1, a rotating shell 6, a reflective plate body 7 and a reflective film 9.

[0033] The rotating shell 6 is rotatably installed on the side of the protective bottom shell 1. The rotating shell 6 and the protective bottom shell 1 can form two states of open and closed. The reflective film 9 is arranged inside the protective bottom shell 1. Specifically, the reflective film is attached to the side of the reflective plate body 7, and the reflective plate body 7 can be detachably installed inside the protective bottom shell 1.

[0034] like Figure 1 As shown in the figure, the protective bottom shell 1 is fixed to the cave wall by wall nails or expansion bolts; when in use, the rotating shell 6 is opened upwards, and the reflective film 9 on the reflective plate body 7 is exposed, and normal measurement can be carried out; when the reflective film 9 is not needed, the rotating shell 6 is closed downwards, and the protective bottom shell 1 and the rotating shell 6 form a protective cavity to protect the reflective film 9 and prevent the reflective film from being contaminated by mud splashed by vehicles; even in the event of a minor collision caused by a construction machine, the reflective film is not easily damaged because of the protection of the protective bottom shell and the rotating shell.

[0035] When the reflective film 9 is soiled or damaged, the reflective plate body 7 can be disassembled, properly cleaned or a new reflective plate body 7 can be attached before the reflective plate body 7 is installed.

[0036] In one embodiment, a mounting hole 2 is provided on the inner bottom of the protective bottom shell 1 , and a pad 3 is fixedly provided on the side of the protective bottom shell 1 at a position corresponding to the mounting hole 2 . The pad 3 is square and has a circular hole corresponding to the mounting hole 2 .

[0037] In one embodiment, the top side of the protective bottom shell 1 is bent upward to form an L-shaped folding plate 4, and an L-shaped sliding hole 5 is opened on the L-shaped folding plate 4. A T-shaped connector 12 is slidingly provided inside the L-shaped sliding hole 5.

The user can manipulate the reflector body 7 and slide the T-shaped connector 12 along the direction of the L-shaped sliding hole 5 to make the T-shaped connector 12 horizontal. At this time, the reflector body 7 is also rotated out of the protective bottom shell 1. The protective bottom shell 1 is then manipulated to rotate 180° around the axis of the connector 8 to achieve reverse operation of the reflector body 7.

[0039] In one embodiment, a through hole 10 is opened at a corner of the reflector body 7 , and a buffer member 11 is installed inside the through hole 10 . The buffer member 11 is used to prevent the reflector body 7 from colliding with the protective bottom shell 1 .

[0040] Specifically, the buffer component 11 includes a first cone shell 1101 and a second cone shell 1104 .

[0042] The first circular pad 110 and the second circular pad 1105 are made of elastic material and can play the role of elastic buffering. The sides of the first cone shell 1101 and the second cone shell 1104 are both provided with gap openings, so that the parts of the first cone shell 1101 and the second cone shell 1104 inserted into the through hole 10 can be elastically deformed, thereby increasing the buffering effect.

[0043] In one embodiment, a protrusion 601 is fixedly connected to the side of the rotating shell 6. When the rotating shell 6 and the protective bottom shell 1 are in a vertical state, the protrusion 601 is tightly pressed between the rotating shell 6 and the protective bottom shell 1, so that the rotating shell 6 and the protective bottom shell 1 are fixed. The protrusion 601 can be made of rubber material, and the surface of the protrusion 601 has anti-slip texture.
