[0025] It should be noted that the support leg 10 described in this embodiment is a telescopic support leg 10 commonly found in a distance measuring bracket 1 , and a tightening bolt is provided on the support leg 10 to fix the telescopic support leg 10 .

[0026] The fine adjustment component 2 is arranged on the bracket 1 , and a level 20 is provided on the fine adjustment component 2 .

[0027] It should be noted that the fine adjustment component 2 described in this embodiment is a common component in the leveling device of the rangefinder 3, including adjustment bolts and a carrier, and the leveling fine adjustment of the device is achieved by fine-tuning the adjustment bolts at the four corners of the carrier.

[0028] The distance meter 3 is rotatably arranged on the fine adjustment component 2 .

[0029] It can be understood that, by setting the rangefinder 3 to rotate, the rotation measurement of the rangefinder 3 is facilitated, and the measurement efficiency of the device is improved.

[0030] The auxiliary leveling assembly 4 may include an electric telescopic rod 40 , a connecting seat 41 and a linkage sleeve 42 .

[0031] The electric telescopic rod 40 is arranged on the support platform 11 , the connecting seat 41 is rotatably connected to the electric telescopic rod 40 , one end of the linkage sleeve 42 is respectively connected to the connecting seat 41 , and the other end of the linkage sleeve 42 is respectively connected to the supporting leg 10 .

[0032] It should be noted that the electric telescopic rod 40 described in this embodiment is provided with a switch button and a battery, which are respectively arranged on the support platform 11, so as to ensure the work (ie normal operation) of the electric telescopic rod 40.

[0033] It should be noted that the connection seat 41 described in this embodiment is rotatably connected to the connection seat 41 via a ball joint, thereby facilitating leveling adjustment in different directions.

[0034] It is understandable that, by connecting the linkage sleeve 42 to the connecting seat 41 and the supporting leg 10 respectively, the extension and retraction of the supporting leg 10 can be controlled when the electric telescopic rod 40 is extended, thereby improving the leveling efficiency of the device.

[0035] The angle fixing assembly 5 may include an abutting fixing member 50 and a pressing limiting member 51 .

[0036] The abutting fixing member 50 is slidably disposed on the connecting seat 41 and is pressed and abutted against the linkage sleeve 42 . The pressing limit member 51 is elastically slidably disposed on the connecting seat 41 and is slidably abutted against the abutting fixing member 50 .

[0037] It is understandable that the pressing limiter 51 can control the displacement of the abutting fixing member 50 on the connecting seat 41 , thereby controlling the limiting position of the abutting fixing member 50 on the linkage sleeve 42 , thereby achieving the fixing of the angle of the supporting leg 10 .

[0038] Specifically, in the actual operation process, the relevant personnel move the device to the specified position, and control the electric telescopic rod 40 to extend, so that the connecting seat 41 is in contact with the ground, and the legs 10 are unfolded. According to the position of the bubble in the spirit level 20 (bubble level 20), the electric telescopic rod 40 is manually moved to quickly move the bubble to the middle position (the middle position is the horizontal position). In addition, the electric telescopic rod 40 drives the support platform 11 to move while shaking, and drives the multiple legs 10 to be telescopically adjusted. When the bubble moves to the middle position to complete the rough leveling, that is, the telescopic length of the multiple legs 10 has been adjusted, the relevant personnel tighten the tightening bolts on the legs 10 to complete the rough leveling of the device.

[0039] The relevant personnel control the pressing limit piece 51 to retract and press the abutting fixing piece 50. After the abutting fixing piece 50 slides over the pressing limit piece 51, the pressing limit piece 51 is controlled to rebound, so that the abutting fixing piece 50 abuts against the pressing limit piece 51, and the abutting fixing piece 50 presses the limiting linkage sleeve 42, so that the linkage sleeve 42 cannot be easily extended or retracted, thereby completing the rapid fixation of the angle of the support leg 10, and continue to adjust the fine adjustment component 2, thereby completing the fine leveling of the rangefinder 3, thereby improving the leveling efficiency of the device.

[0040] In one embodiment of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the connection base 41 may include a connection rod 410 and a base 411 .

[0041] The electric telescopic rod 40 is rotatably connected to the connecting rod 410 . The connecting rod 410 is disposed on a base 411 . The linkage sleeve 42 is connected to the base 411 .

[0042] It should be noted that the base 411 described in this embodiment is triangular in shape, and three legs 10 are provided, and the shape of the legs 10 corresponds to that of the base 411. In this way, during rough leveling, the legs 10 corresponding to each direction of each base 411 can be better controlled to improve the leveling efficiency of the device.

[0043] In one embodiment of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the linkage sleeve 42 may include a first sleeve 420 and a second sleeve 421 .

[0044] Among them, the first sleeve 420 is respectively connected to the base 411, one end of the second sleeve 421 extends into the first sleeve 420 and is slidably connected to the first sleeve 420, the other end of the second sleeve 421 is respectively connected to the support leg 10, and one end of the abutment fixing member 50 passes through the first sleeve 420 and is pressed and abutted with the second sleeve 421.

[0045] It should be noted that a through hole is provided on the first sleeve 420 described in this embodiment to facilitate the abutment between the fixing member 50 and the second sleeve 421 .

[0046] In one embodiment of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the abutting fixing member 50 may include a sliding block 500 and an elastic fixing rod 501 .

[0047] Among them, the sliding block 500 is slidably set on the connecting rod 410, and the sliding block 500 slides and abuts against the pressing limiter 51, one end of the elastic fixing rod 501 is respectively connected with the sliding, and the other end of the elastic fixing rod 501 passes through the first sleeve 420 and presses and abuts against the second sleeve 421.

[0048] It is understandable that, through the elastic setting of the elastic fixing rod 501 , the sliding block 500 can be brought into contact with the pressing and limiting member 51 , thereby ensuring the limiting effect of the elastic fixing rod 501 on the second sleeve 421 .

[0049] In one embodiment of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, friction plates are respectively provided on the second sleeve 421 and the elastic fixing rod 501 .

[0050] It can be understood that the setting of the friction plate further improves the limiting effect of the elastic fixing rod 501 and the second sleeve 421.

[0051] In one embodiment of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the pressing limiter 51 may include a limit block 510 , a spring 511 and a pressing rod 512 .

[0052] Among them, the limit blocks 510 are respectively slidably set in the connecting rod 410, the sliding block 500 slides and abuts against the limit blocks 510, the spring 511 is set between the limit blocks 510, one end of the pressing rod 512 is respectively connected to the limit blocks 510, and the other end of the pressing rod 512 extends to the outside of the connecting rod 410.

[0053] It can be understood that, by providing the spring 511 , the automatic reset of the limit block 510 is achieved.

[0054] Specifically, in the actual operation process, the relevant personnel move the device to the specified position, and control the electric telescopic rod 40 to extend, so that the connecting seat 41 is in contact with the ground, and the legs 10 are unfolded. According to the position of the bubble in the spirit level 20 (bubble level 20), the electric telescopic rod 40 is manually moved to quickly move the bubble to the middle position (the middle position is the horizontal position). In addition, the electric telescopic rod 40 drives the support platform 11 to move while shaking, and drives the multiple legs 10 to be telescopically adjusted. When the bubble moves to the middle position to complete the rough leveling, that is, the telescopic length of the multiple legs 10 has been adjusted, the relevant personnel tighten the tightening bolts on the legs 10 to complete the rough leveling of the device.

[0055] The relevant personnel controls the pressing rod 512 to shrink the pressing rod 512 and press the sliding block 500 downward. After the sliding block 500 slides over the limit block 510, the pressing rod 512 is controlled to rebound, so that the sliding block 500 abuts against the limit block 510, and when the sliding block 500 moves downward, it drives the elastic fixing rod 501 to press the second sleeve 421 downward, so that the second sleeve 421 cannot be easily extended or retracted, thereby completing the rapid fixation of the angle of the support leg 10, and continuing to adjust the fine adjustment component 2, thereby completing the fine leveling of the rangefinder 3, thereby improving the leveling efficiency of the device.

[0056] In summary, the leveling device of the rangefinder of the embodiment of the utility model does not need to repeatedly adjust the extension length of the legs, can quickly and roughly level the bracket, and can quickly fix the supporting angle of the legs, thereby improving the leveling efficiency of the rangefinder.
