Description

Technical Field

[0001] The utility model relates to the technical field of ranging support, and more specifically, to a fixing and supporting mechanism for a rangefinder. Background Art

[0002] In the construction industry, in order to ensure that the lengths of various positions inside and outside building facilities are appropriate, a rangefinder is often used during construction to conduct a full range of measurements on building facilities and foundations on site, thereby increasing the accuracy and convenience of subsequent construction project costs. When using a rangefinder, a fixing and supporting mechanism is required for support. For example, a fixing and supporting mechanism for a rangefinder disclosed in the prior art publication number (CN219588612U) pushes two clamping plates to both sides, so that an appropriate size appears between the clamping plates, and then the rangefinder is placed between the two clamping plates. After placing it, release the clamping plates, and the clamping and fixing of the rangefinder can be completed through the springs on both sides of the clamping plates. After the clamping and fixing is completed, the measurement can be carried out. When the height needs to be adjusted, start the first motor. At this time, the output end of the first motor drives the rotating shaft to rotate. Since the two rotating shafts are meshed with each other through transmission wheels, the two rotating shafts can be simultaneously driven to rotate. By meshing the transmission wheels on both sides with the racks, the two support legs can be quickly pushed down or pulled up.

[0003] When the above device is in use, the output end of the first motor drives the rotating shaft to rotate, and at the same time drives the two rotating shafts to rotate simultaneously. By meshing the transmission wheels on both sides with the racks, the two support legs can be quickly pushed down or pulled up. With the simultaneous extension and retraction of multiple support legs, the height of the overall support mechanism can be adjusted conveniently and efficiently. At the same time, due to the consistent driving force, multiple support legs can be kept consistent when extending and retracting. When adjusting the height, not only is the efficiency higher, but the stability during adjustment is also better. However, its structure is relatively complex, and when dealing with uneven ground, the rangefinder cannot be adjusted to a state parallel to the horizontal line in time, thus affecting its applicability. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a fixing and supporting mechanism for a rangefinder. The technical problem to be solved by the utility model is: how to facilitate the applicability of the rangefinder when supported on different ground surfaces.

[0005] To achieve the above object, the utility model provides the following technical solution: A fixing and supporting mechanism for a rangefinder, including a rangefinder mounting frame, a rotating support member is provided at the lower end thereof, a support rod is provided outside the lower end of the rotating support member, an adaptation chute is provided on the outer end surface of the support rod, an arc chute is provided on one side of the inner end surface of the adaptation chute, an adjusting support rod is provided inside the adaptation chute, and a support anti-slip pin is provided at the lower end of the adjusting support rod;

A clamping tooth is arranged on the end face of the arc-shaped slider close to the adjusting support rod. A adjusting knob is arranged on the lower side of the inner end face of the support rod. The rotating rod of the adjusting knob passes through the end face of the support rod and extends to the inner side of the support rod. An adjusting gear is arranged on the rotating rod of the adjusting knob inside the matching chute.

[0007] In a preferred embodiment, an inlaid level is arranged on the outer end face of the rotating support member. A connecting rotating rod is arranged at the connection between the support rod and the rotating support member. A support sliding rod is arranged in the middle of the lower end of the rotating support member.

[0008] A limiting clamping block is arranged at the lower end of the support sliding rod. A support sliding sleeve is arranged on the outer end face of the support sliding rod. A support limiting rod is arranged outside the support sliding sleeve.

[0009] In a preferred embodiment, rotating connection blocks are arranged at both ends of the support limiting rod. The support limiting rod is connected to the outer end face of the support sliding sleeve and the inner end face of the support rod through the rotating connection blocks.

[0010] The number of the inlaid levels, the support limiting rods and the support rods are all provided with a plurality of them, and they are arranged in an annular array state outside the center point in the top view direction of the rangefinder mounting frame.

[0011] In a preferred embodiment, a locking knob is arranged on the upper side of the outer end face of the adjusting support rod. The outer end face of the support sliding rod is adapted to the inner end face of the support sliding sleeve.

[0012] In a preferred embodiment, the inner end face of the matching chute is adapted to the outer end face of the adjusting support rod. The outer end face of the arc-shaped slider is adapted to the inner end face of the arc-shaped chute.

The adjusting gear is adapted to the clamping tooth through meshing.

[0014] The technical effects and advantages of the present utility model:

[0015] When the utility model is actually used, under the corresponding setting states of the supporting sliding rod, the supporting sliding sleeve, the rotating connecting block and the supporting limiting rod, the stability of the expansion adjustment of the supporting rod can be effectively increased, so that a plurality of supporting rods can be expanded simultaneously. At the same time, under the corresponding setting states of the adjusting supporting rod, the adapting sliding groove, the arc-shaped sliding block and the arc-shaped sliding groove, the stability of the adjusting supporting rod during height adjustment can be effectively increased. At the same time, under the corresponding setting states of the adjusting knob, the engaging teeth and the adjusting gear, the adjusting gear can be driven to rotate by rotating the adjusting knob, so as to conveniently fine-tune the height of the adjusting supporting rod, so as to conveniently adjust the rangefinder according to the inclination angle of different ground surfaces and conveniently adjust it to a state parallel to the horizontal plane.
