Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example.

Example 1

Referring to Figures 1, 2, 3 and 5, an engineering measurement device includes a laser measuring instrument 1 and a fixing mechanism. The fixing mechanism is fixed on the laser measuring instrument 1. The fixing mechanism includes two fixing plates 2 and two connecting rods 3. The two ends are respectively fixed on two fixing plates 2 . Both connecting rods 3 are U-shaped structures, and the two connecting rods 3 are arranged symmetrically. The two connecting rods 3 of the 匚-shaped structure will not affect the replacement of the battery on the laser measuring instrument 1 when in use.

It also includes an anti-drop mechanism, which is used to protect the laser measuring instrument 1, and can prevent the laser measuring instrument 1 from being broken. The air bag 5 has a cylindrical structure, and the air bag 5 of the cylindrical structure is set on the lanyard 4 .

Working principle: when the engineering measurement equipment is in use, use the fixing mechanism to fix the lanyard 4 on the laser measuring instrument 1, and then hang the lanyard 4 around the neck. Then, when the laser measuring instrument 1 is not held, the laser measuring instrument 1 can also be hung on the chest. 5 On the lanyard 4, the airbag 5 is in contact with the skin of the neck, which can prevent the lanyard 4 from rubbing the skin of the neck and ensure the safety of people when using it.

Example 2

On the basis of embodiment 1, with reference to Figs. 1-5, as another preferred embodiment of the present invention, the difference from embodiment 1 is that since the airbag 5 can move on the hanging rope 4 through a plurality of rings 6, when moving, the plurality of rings 6 must rub against the surface of the hanging rope 4, which is easy to damage the surface of the hanging rope 4, and the hanging rope 4 includes a wear-resistant sleeve 7 and a core rope 8. The polyester sheath has good friction resistance, and when a plurality of rings 6 move on the wear-resistant sheath 7, it is not easy to cause damage to the wear-resistant sheath 7, and it protects the core rope 8, and the wear-resistant sheath 7 and the core rope 8 are all fixed on the fixing mechanism. Both ends of the wear-resistant sleeve 7 and the core rope 8 are respectively fixed on the two fixing plates 2 .

The air exchange assembly includes an air guide tube 9, a sealing gasket 10 and a sealing cover 11. The air guide tube 9 is communicated and fixed on the air bag 5, and the sealing pad 10 is fixed inside the air guide tube 9. There is a gap running through the sealing pad 10. The air nozzle is pulled out from the air duct 9, and with the assistance of the resilience of the sealing gasket 10, the gaps of the sealing gasket 10 are merged together again. Although the sealing gasket 10 cannot completely prevent the air bag 5 from leaking, it can reduce the air leakage speed of the air bag 5 to a large extent. The sealing cover 11 is threaded on the air guiding tube 9. After the sealing cover 11 is arranged on the airway tube 9, the situation of air leakage in the air bag 5 can be avoided.

Working principle: when in use, due to the need to frequently move the airbag 5 at the position of the lanyard 4, multiple moving rings 6 rub against the wear-resistant sleeve 7 on the lanyard 4. The setting of the wear-resistant sleeve 7 can improve the wear resistance of the lanyard 4, thereby increasing the service life of the lanyard 4, thereby preventing the lanyard 4 from being broken due to wear. It is also a way to protect the laser measuring instrument 1. Insert it in the air duct 9, and let the top of the air outlet of the air cylinder pass through the gap of the sealing gasket 10, and use the air cylinder to inflate the air bag 5. After the air cylinder is full of gas, the air cylinder is pulled out, and the sealing cover 11 is screwed on the air guiding pipe 9. The sealing cover 11 can prevent the air bag 5 from leaking.

The above is only a preferred specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Any person familiar with the technical field within the technical scope disclosed in the utility model, according to the technical scheme of the utility model and its utility model design to make equivalent replacements or changes, should be covered within the scope of protection of the utility model.
