[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0024] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] like Figures 1 to 4 As shown, a high-precision ultra-thin slide comprises a slide body 10, wherein the slide body 10 comprises a working plate 20 and a bottom plate 30 movably connected to the working plate 20, and the slide body 10 further comprises a shock-absorbing module 40 connected to the bottom of the bottom plate 30; the shock-absorbing module 40 comprises a shock-absorbing box 41, a plurality of first shock-absorbing assemblies 50 and a plurality of second shock-absorbing assemblies 60; a placement cavity 42 is provided inside the shock-absorbing box 41, and the plurality of first shock-absorbing assemblies 50 and the plurality of second shock-absorbing assemblies 60 are respectively fixed inside the placement cavity 42; the top of the first shock-absorbing assembly 50 is fixedly connected to the bottom plate 30; the second shock-absorbing assembly 60 comprises a support member 61 and a buffer box 70, and the support member 61 is connected to the top of the buffer box 70.

[0026] Furthermore, if Figure 4 As shown, a differential adjustment assembly 80 for fine adjustment is provided on the outer side of the working plate 20, and the differential adjustment assembly 80 includes a differential head 81, a differential shaft 82 connected to one end of the differential head 81, a first connecting block 83 for rotating the differential shaft 82, and a second connecting block 84 connected to the tail of the differential shaft 82, the lower end of the first connecting block 83 is fixed to one side of the bottom plate 30, and the second connecting block 84 is fixedly connected to one side of the working plate 20. Specifically, through the differential adjustment assembly 80, precise adjustment is effectively achieved, and the use accuracy of the slide body 10 is improved.

[0027] Furthermore, if Figure 1 As shown, a tightening screw 21 is connected to the side of the working plate 20 away from the differential adjustment assembly 80, and the tightening screw 21 is used to fix the working plate 20. In this way, when the working plate 20 is adjusted to the set position, only the tightening screw 21 can be locked to fix the working plate 20, further improving the use accuracy of the slide body 10.

[0028] Furthermore, if Figure 1 As shown, a limiting plate 31 is fixedly connected to one side of the bottom plate 30, and a limiting slot 32 is provided at the center of the limiting plate 31, and the limiting slot 32 is movably connected to the tightening screw 21. In this way, the tightening screw 21 is limited in its movement in the limiting slot 32, so that the tightening screw 21 is limited, and the bottom plate 30 and the working plate 20 are ensured to move relative to each other.

[0029] Furthermore, if Figure 1 As shown, a plurality of fixing screws 33 are connected to the lower part of the limit plate 31, and the limit plate 31 is connected to one side of the bottom plate 30 through the plurality of fixing screws 33. The limit plate 31 is fixedly connected to the bottom plate 30 through the fixing screws 33, so as to ensure the relative movement between the bottom plate 30 and the working plate 20.

[0030] Furthermore, if Figure 1 As shown, a first slot 43 is provided on one side of the shock absorbing box 41, and the first slot 43 is used for sliding of the fixing screw 33. Specifically, in the process of buffering the impact force, the fixing screw 33 is prevented from colliding with the shock absorbing box 41 to damage the slide body 10, and the service life is effectively improved.

[0031] Furthermore, if Figure 2 and Figure 4 As shown, the damping box 41 has a second slot 44 on one side away from the first slot 43, and the second slot 44 is used for the first connecting block 83 to move. Specifically, in the process of buffering impact force, the first connecting block 83 is prevented from colliding with the damping box 41 to damage the slide body 10, which effectively improves the service life.

[0032] Furthermore, if Figure 2As shown, the number of the first shock absorbing assembly 50 and the second shock absorbing assembly 60 is set to four, and the first shock absorbing assembly 50 includes a connecting column 51, a buffer spring 52 sleeved on the connecting column 51, the upper end of the buffer spring 52 is connected to the bottom of the bottom plate 30, and the lower end of the buffer spring 52 is connected to the bottom of the placement cavity 42. In this way, the setting of multiple shock absorbing assemblies further improves the shock absorbing and buffering effect of the slide body 10, and has strong practicality.

[0033] Furthermore, if Figure 1 and Figure 3 As shown, the support member 61 is a connecting bolt, and the connecting bolt passes through the bottom plate 30 and is connected to the top of the buffer box 70. In this way, the connecting bolt effectively connects the bottom plate 30 and the buffer box 70 stably, effectively improving the use accuracy.

[0034] Furthermore, if Figure 3 As shown, the buffer box 70 includes a box body 71, a connecting plate 72 disposed inside the box body 71, and an airbag spring 73 connected to the bottom of the connecting plate 72. The bottom of the support member 61 passes through the box body 71 and is fixedly connected to the top of the connecting plate 72. The airbag spring 73 is provided to effectively alleviate the impact force received, greatly improving the use accuracy of the slide body 10.

[0035] The working principle of this utility model:

[0036] When the slide body 10 is working, the external device vibrates and generates impact force, and the base plate 30 transmits the impact force to the shock absorbing module 40. At the same time, the impact force is also transmitted from the shock absorbing module 40 to a number of first shock absorbing components 50 and a number of second shock absorbing components 60, wherein part of the impact force is transmitted to the buffer spring 52 of the first shock absorbing component 50, and the other part of the impact force is transmitted to the airbag spring 73 in the buffer box 70 of the second shock absorbing component 60. The airbag spring 73 and the buffer spring 52 generate elastic deformation under the action. While the elastic deformation is generated, the impact force will be effectively buffered. Through double buffering, the shock absorbing effect of the slide body 10 is improved, the influence of the impact force and the slide body 10 is greatly reduced, and the slide body 10 is effectively prevented from being offset during operation, which greatly improves the accuracy of use.

[0037] The above only expresses the preferred technical solution of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
