[0038] Example 1
[0039] Reference Figure 1-5 , which is the first embodiment of the utility model, provides a self-locking mechanism, which includes a main lock unit 100, including a main lock body 101, a pressing component 103 arranged inside the main lock body 101, a transmission component 104 arranged on both sides of the pressing component 103, and a buckle component 105 arranged at one end of the transmission component 104. The pressing component 103 drives the transmission component 104 so that the buckle component 105 can be retracted, thereby separating the protection body 301 from the main lock body 101.
[0040] The secondary lock unit 200 includes a secondary lock body 201, and a snap-on assembly 202 arranged on the inner side of the secondary lock body 201 and corresponding to the snap-on assembly 105. The secondary lock unit 200 and the snap-on assembly 105 are snap-connected with each other, thereby fixing the protective body 301 on the main lock body 101, so that the protective body 301 protects the static level 500 inside the main lock body 101.
[0041] The buckle assembly 105 includes a spring column 105a, a clamping plate 105b arranged at one end of the spring column 105a, a limiting plate 105c arranged on the spring column 105a, arranged in the main lock body 101, and slidably connected to the spring column 105a, and a return spring 105d which is sleeved on the spring column 105a, one end of which is arranged on the limiting plate 105c, and the other end of which is arranged on the connecting plate 105e. The return spring 105d provides elastic force to the connecting plate 105e and the clamping plate 105b on one side thereof, so that they can be tightly clamped together with the clamping assembly 202, thereby increasing the stability of the clamping between the buckle assembly 105 and the clamping assembly 202.
[0042] Among them, a clamping bevel 202a is provided on the inner side of the clamping component 202, and connecting nuts 102 are provided on both sides of the main lock body 101. There are two groups of clamping bevels 202a. The inclination angle of the clamping bevel 202a is adapted to the inclination angle of the clamping plate 105b, so that the clamping component 202 and the buckle component 105 can be perfectly snapped together, so that the protective body 301 can be firmly fixed on the main lock body 101, and the two groups of clamping bevels 202a are snapped with the buckle component 105, which further ensures the connection stability between the protective body 301 and the main lock body 101.
[0043] During use, by setting the snap assembly 105 and the snap assembly 202, when the snap assembly 202 slides downward, the elasticity of the return spring 105d itself will push the connecting plate 105e and the snap plate 105b at one end thereof to extend outward, so that the snap plate 105b and the snap assembly 202 are snapped together to lock the snap assembly 202, thereby fixing the secondary lock unit 200 on the main lock unit 100 for self-locking. At the same time, the maintenance personnel can also press the pressing assembly 103 to move it downward, thereby driving the spring column 105a to retract into the main lock body 101 through the transmission assembly 104, so that the snap plate 105b is separated from the snap assembly 202, thereby facilitating the maintenance personnel to remove the secondary lock unit 200 from the main lock unit 100, thereby increasing the comfort of use for the maintenance personnel.
[0044] Example 2
[0045] Reference Figure 1-7, which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: the self-locking mechanism also includes a fixing unit 400 arranged on both sides of the main lock body 101, and the fixing unit 400 includes a fixing plate 401 arranged on the main lock body 101, and a fixing bolt 402 arranged on the inner side of the fixing plate 401, and a tooth plate 403 arranged at one end of the fixing bolt 402. The moving direction of the fixing bolt 402 is limited by the fixing plate 401, so as to ensure that the two sets of tooth plates 403 are on the same horizontal line, thereby balancing the fixing force of the tooth plates 403 on both sides of the negative water pressure plate 501, and increasing the fixing stability of both sides of the negative water pressure plate 501.
[0046] Compared with Example 1, further, tooth grooves 404 are equidistantly provided on one side of the tooth plate 403, and the contact area between the tooth plate 403 and the negative water pressure plate 501 is increased through the tooth grooves 404, so that the tooth plate 403 fixes the negative water pressure plate 501 more tightly and firmly.
[0047] During use, the staff controls the fixing bolt 402 to rotate and adjust inside the fixing plate 401 according to the model and size of the negative water pressure plate 501, thereby adjusting the distance between the two sets of tooth plates 403 to match the size of the negative water pressure plate 501, and then installing the negative water pressure plate 501 between the two sets of tooth plates 403, and then rotating and adjusting the fixing bolt 402 again to make the two sets of tooth plates 403 fit tightly with the fixing plate 401, thereby fixing it, and then static levels of different sizes and models can be fixed in their protective covers, so that the static levels can perform measurement work smoothly and safely.
[0048] The remaining structures are the same as those of Example 1.

[0051] The protection unit 300 includes a protection body 301 arranged on the secondary lock unit 200, observation windows 302 arranged on both sides of the protection body 301, connection holes 303 arranged on both sides of the protection body 301 and located below the observation windows 302, and handles 304 arranged on the other two sides of the protection body 301. The observation window 302 makes it convenient for the staff to observe and monitor the working condition of the internal static level 500, thereby increasing the comfort of the staff.
[0052] Compared with Example 2, further, the size of the tooth plate 403 is adapted to the size of the negative water pressure plate 501 .
[0053] During use, the staff first selects a suitable measuring position for the static level 500, then fixes the main lock body 101 at the measuring position by passing the bolt through the connecting nut 102, and then installs the static level 500 on the main lock body 101 and fixes it through two sets of fixing units 400. Then the staff connects the cable to the power jack 502 and the level tube 503 respectively, and passes the other end of the cable through the connecting hole 303. Then the staff rotates the adjustment screw 505 and observes the internal situation of the horizontal tracker 504 to determine whether the static level 500 can perform the measurement work. After the installation and debugging are completed, the staff holds the protective body The handles 304 on both sides of 301 are used, and the protection body 301 is aligned with the main lock body 101, and then it is slowly inserted, so that the secondary lock unit 200 and the buckle assembly 105 are engaged and fixed with each other, and then the protection body 301 is fixed on the main lock body 101, and finally the cable outside the connecting hole 303 is connected with other measuring devices, so that the static level 500 starts measuring, and then the protection body 301 can isolate the external dust and gravel on the outside of the static level 500, so as to ensure the accuracy of the static level measurement work, and at the same time prevent dust and impurities from causing damage to the static level 500, thereby increasing the safety and service life of the static level 500.
[0054] The remaining structure is the same as that of Example 2.
[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
