[0031] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0032] A protective device for a level instrument, such as Figure 1As shown, it includes a support frame 1, a fixed truncated table 2 is fixedly connected to the middle of the upper end of the support frame 1, a level instrument body 3 is arranged on the upper end of the fixed truncated table 2, a protective mechanism 4 is arranged on the fixed truncated table 2, and the protective mechanism 4 includes a fixed sleeve 41 sleeved on the upper end of the fixed truncated table 2, a protective sleeve 42 is arranged on the outer side of the fixed sleeve 41, and the protective sleeve 42 is a circular structure. The diameter of the protective sleeve 42 is greater than the total length of the level instrument body 3, and the level instrument body 3 can be protected within the middle range of the protective sleeve 42. The fixed sleeve 41 has two sides and front and rear fixed links. A damper 43 is connected, and one end of the damper 43 away from the fixed sleeve 41 is fixedly connected to the protective sleeve 42. A knob 44 is threadedly connected to the middle of one side of the fixed sleeve 41, and the knob 44 is threadedly connected to the fixed truncated table 2. When the device accidentally topples over, the protective sleeve 42 will first contact the ground. The damper 43 can buffer the impact force, thereby preventing the level body 3 from directly hitting the ground and causing damage. The force buffering can also reduce the impact force on the internal precision structure of the level body 3, thereby protecting the level body 3 as a whole.

[0033] The upper end of the protective sleeve 42 is fixedly connected to a placement seat 5, and a transparent protective cover 6 is inserted into the upper end of the placement seat 5. The level body 3 is located inside the transparent protective cover 6. When not in use temporarily, the transparent protective cover 6 can be placed on the upper end of the level body 3 to prevent dust and protect it.

[0034] A limiting mechanism 7 is provided between the placement seat 5 and the transparent protective cover 6. An elastic mechanism 8 is provided on the limiting mechanism 7. The limiting mechanism 7 includes a sleeve 71, a pin 72, and a button 73. The two sleeves 71 are fixedly connected to the middle of the two sides of the placement seat 5. The pin 72 is inserted in the middle of the sleeve 71. The pin 72 runs through the placement seat 5 and the transparent protective cover 6. The button 73 is fixedly connected to one end of the pin 72. The elastic mechanism 8 includes a slide plate 81 and a spring 82. The slide plate 81 is fixedly sleeved on the pin 72. The slide plate 81 is connected to the inside of the sleeve 71. The spring 82 is arranged inside the sleeve 71 and is sleeved on the pin 72.

[0035] When installing the transparent protective cover 6, it is only necessary to pull the buttons 73 at both ends. The buttons 73 drive the pin shaft 72 to move. The movement of the pin shaft 72 drives the slide plate 81 to move and squeeze the spring 82. The pin shaft 72 moves out of the middle of the placement seat 5, and then the transparent protective cover 6 is plugged into the upper end of the placement seat 5. The transparent protective cover 6 is rotated. When the hole on the transparent protective cover 6 that cooperates with the pin shaft 72 is rotated to a suitable position, the rebound force of the spring 82 drives the slide plate 81 to push the pin shaft 72 to be plugged into the transparent protective cover 6 to fix it. In this way, the staff can rest assured to temporarily place the device in the required position for use. When using it again, pull out the pin shaft 72 and remove the transparent protective cover 6. The installation and disassembly are convenient, and the protection of the level meter body 3 is more comprehensive.

[0036] When the utility model is implemented, Figure 1-7 As shown, when in use, before installing the level body 3, the fixing sleeve 41 is sleeved on the upper end of the fixed truncated table 2, the knob 44 is threadedly connected to the fixed truncated table 2 to fix the fixing sleeve 41, and then the level body 3 is installed to the upper end of the fixed truncated table 2.

[0037] When the device accidentally topples over, the circular protective cover 42 will first touch the ground, and the damper 43 can buffer the impact force, thereby preventing the level body 3 from directly hitting the ground and causing damage. The force buffering can also reduce the impact force on the precise structure inside the level body 3, thereby protecting the level body 3 as a whole.

[0038] When the staff temporarily leaves and does not use the device, the transparent protective cover 6 can be mounted on the upper end of the level body 3 to prevent dust and protect it. When installing the transparent protective cover 6, it is only necessary to pull the knobs 73 at both ends. The knobs 73 drive the pin 72 to move. The movement of the pin 72 drives the slide plate 81 to move and squeeze the spring 82. The pin 72 moves out of the middle of the placement seat 5, and then the transparent protective cover 6 is plugged into the upper end of the placement seat 5. The transparent protective cover 6 is rotated. When the hole on the transparent protective cover 6 that cooperates with the pin 72 is rotated to a suitable position, the rebound force of the spring 82 drives the slide plate 81 to push the pin 72 to be plugged into the transparent protective cover 6 to fix it. In this way, the staff can rest assured to temporarily place the device in the required position for use. When using it again, pull out the pin 72 and remove the transparent protective cover 6. The installation and disassembly are convenient, and the protection of the level body 3 is more comprehensive.

[0039] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
