However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] like Figures 1-7 As shown in the figure, this utility model discloses a laser rangefinder adjustment device, mainly including an adjustment plate 1 and an L-shaped fixing plate 2. The adjustment plate 1 and the L-shaped fixing plate 2 can be made of metal. A first laser rangefinder body through hole 1-1 is formed on the adjustment plate 1, and a second laser rangefinder body through hole 2-1 is formed on the vertical part of the L-shaped fixing plate 2 parallel to the adjustment plate 1. After the body of the laser rangefinder 3 passes through the first laser rangefinder body through hole 1-1 and the second laser rangefinder body through hole 2-1 in sequence, the base 3-1 of the laser rangefinder 3 is fixed to the outer side of the adjustment plate 1. The base 3-1 of the laser rangefinder 3 and the adjustment plate 1 can be fixed by built-in screws, or by other structures in the prior art. The connection method between the two is not the inventive point of this application, so it will not be described in detail.

[0020] Furthermore, such as Figures 1-4As shown, an elastic adjustment assembly and a locking screw 4 are provided between the vertical portion of the adjusting plate 1 and the L-shaped fixed plate 2. The elastic adjustment assembly is used to adjust the positional relationship between the vertical portion of the adjusting plate 1 and the L-shaped fixed plate 2, and the locking screw 4 is used to lock the positions of the adjusting plate 1 and the L-shaped fixed plate 2. In the device described in this application, the laser rangefinder is fixed on the adjusting plate, and the adjusting plate and the fixed plate are connected by the elastic adjustment assembly. The yaw axis and pitch axis of the laser rangefinder are adjusted by tightening and loosening the adjusting screw. After adjustment, the adjusting plate and the fixed plate are fixed with the locking screw.

[0021] Furthermore, such as Figures 3-5 As shown, in this application, the adjusting plate 1 has several blind holes 1-2 for adjusting screws, several first spring through holes 1-3, and several first locking threaded holes 1-4 formed on two adjacent sides. A plurality of threaded holes 2-2 for adjusting screws are formed on the vertical portion corresponding to the blind holes 1-2. A plurality of second spring through holes 2-3 are formed on the vertical portion corresponding to the first spring through holes 1-3. A locking screw through hole 2-4 is formed on the vertical portion corresponding to the first locking threaded hole 1-4. Preferably, as... Figure 5 As shown, three blind holes 1-2 for adjusting screw mounting can be provided, located on the front side, the lower side, and the intersection of the front and lower sides of the adjusting plate 1, respectively. Two first locking threaded holes 1-4 can be provided, located on the front side and the lower side between the two blind holes 1-2 for adjusting screw mounting. Four first spring through holes 1-3 can be provided, located between the blind holes 1-2 for adjusting screw mounting and the first locking threaded holes 1-4, respectively. It should be noted that the number of blind holes 1-2 for adjusting screw mounting, the first spring through holes 1-3, and the first locking threaded holes 1-4 in this application can be other specific numbers besides the specific numbers mentioned above, and those skilled in the art can set them according to actual needs.

[0022] Furthermore, such as Figures 3-4 As shown, the key components in this application are the elastic adjustment assembly and the locking screw 4. The elastic adjustment assembly includes at least three adjusting screws 5, the same number as the number of blind holes 1-2 for the adjusting screws, and four spring assemblies, the same number as the number of through holes 1-3 for the first springs. Since there are three blind holes 1-2 for the adjusting screws in this application, there are also three adjusting screws 5. Similarly, since there are four through holes 1-3 for the first springs in this application, there are also four spring assemblies.

[0023] like Figures 1-4As shown, in the present application, the adjusting screw 5 first passes through the vertical part of the L-shaped fixing plate 2, and then the end thereof enters into the corresponding adjusting screw mounting blind hole 1-2. Further, in the present application, in order to increase the contact area and provide structural strength for locking screw locking, the end of the adjusting screw 5 corresponding to the adjusting screw mounting blind hole 1-2 is in a convex spherical surface structure, and the bottom surface of the adjusting screw mounting blind hole 1-2 corresponding to the convex spherical surface structure is in a concave spherical surface structure.

[0024] Further, as shown, Figures 1-4 and Figure 7 In the present application, each spring assembly includes one spring 6 and two clamping columns. One end of the spring 6 is located in the first spring passing hole 1-3, and this end is fixed in the first clamping column mounting groove outside the first spring passing hole 1-3 through the first clamping column 7. The other end of the spring 6 is located in the second spring passing hole 2-3, and this end is fixed in the second clamping column mounting groove outside the second spring passing hole 2-3 through the second clamping column 8. Through the limiting action of the first clamping column 7 and the second clamping column 8, the spring is in a stretched state. In addition, the spring can be tightened or loosened by rotating the first clamping column 7 and the second clamping column 8. The locking screw 4 first passes through the locking screw passing hole 2-4, and then is fixedly connected with the first locking screw hole 1-4.

[0025] Further, in order to facilitate the rotation of the locking screw 4 and the adjusting screw 5, an internal hexagonal groove is formed on the driving end of the locking screw 4 and the adjusting screw 5, which facilitates the rotation of the locking screw 4 and the adjusting screw 5 by using an internal hexagonal driver.

[0026] In addition, since the actual adjustment angle of the laser range finder of the optoelectronic pod is within 2 degrees, the diameter of the two locking screw passing holes 2-4 on the fixing plate is slightly larger than the diameter of the locking screw 4, which can meet the adjustment stroke requirement. In the present application, the laser range finder is fixed on the adjusting plate, the adjusting plate and the fixing plate are connected by the spring assembly, the heading axis and the pitch axis of the laser range finder are adjusted by tightening and loosening the adjusting screw, and after the adjustment is completed, the adjusting plate and the fixing plate are fixed by the locking screw to complete the position locking of the two, preventing the change of position during use.

[0027] In summary, the present application has the advantages of small structure, small volume, light weight, simple structure, adjustment and locking position in the same direction, convenient operation, and more favorable application of the optoelectronic pod with multiple optical modules.
