Technical Field

[0001] The present invention relates to the technical field of hand-held laser distance meters, and more particularly to a holder for a portable hand-held laser distance meter.

Background Art

[0002] A hand-held laser distance meter is a portable measuring device that uses laser technology to quickly and accurately measure the distance between a target object and the device. The hand-held laser distance meter calculates the time or phase difference from when a laser beam is emitted until the light beam is reflected back to the receiver, and combines it with the speed of light to calculate the distance value. This device is small in volume, easy to operate, and widely applied in fields such as construction, measurement, interior decoration, real estate, and sports. Hand-held laser distance meters generally have characteristics such as high precision, multi-function (e.g., measurement of area and volume), and data storage. Some models support Bluetooth connection and data transmission, further improving work efficiency. Its portability and ease of use make it an ideal tool for on-site measurement tasks.

[0014] To make the above objects, features, and advantages of the present invention clearer and more understandable, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] In the following description, many specific details are set forth to facilitate a complete understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0016] Next, the "one embodiment" or "embodiment" referred to in this specification refers to specific features, structures, or characteristics that may be included in at least one implementation form of the present invention. References to "in one embodiment" in various places in this specification do not necessarily all refer to the same embodiment, nor are they separate or alternative embodiments that are mutually exclusive with other embodiments.

[0017] Embodiment Referring to FIGS. 1 to 4, these figures are embodiments of the present invention, and the embodiments provide a holder for a portable handheld laser distance meter. The holder for the portable handheld laser distance meter includes a support mechanism 100 and a fixing mechanism 200. The support mechanism 100 includes a support plate 110, a distance meter 120 provided at the top of the support plate 110, a plurality of support legs 130 hinge-connected to the bottom of the support plate 110, a support box 140 fixedly attached to the end of the support leg 130, an adjustment rod 150 hinge-connected to the surface of the support leg 130, a screw sleeve 160 fixedly attached between the plurality of adjustment rods 150, and a screw 170 rotatably attached to the bottom of the support plate 110 and for driving the movement of the screw sleeve 160. The fixing mechanism 200 includes an insertion and fixing member 210 for improving the stability of the support plate 110 inserted and fixed to the support box 140, and a moving member 220 for facilitating the movement of the support box 140.

[0018] Here, through the cooperation of the insertion and fixing member 210 and the moving member 220, the use stability of the distance meter 120 is improved, the needs in the frequent moving measurement tasks of the distance meter 120 are met, the problem that the conventional distance meter 120 is unstable under bad weather conditions and difficult to adapt to frequent moving measurement tasks is solved, the effect of measurement stability is improved, and it is easy to operate and the working intensity is reduced.

[0019] Specifically, the insertion and fixing member 210 includes an insertion rod 211 slidably attached to the support box 140, a return spring 212 fixedly attached to the surface of the insertion rod 211, a driving toothed plate 213 fixedly attached to the surface of the insertion rod 211, and a transmission gear 214 rotatably attached to the cavity of the support box 140 and meshing with the driving toothed plate 213.

[0020] Furthermore, the insertion and fixing member 210 further includes a disc 215 fixedly attached to the surface of the insertion rod 211, and a locking rod 216 for locking the disc 215.

[0021] Here, a circular hole into which the locking rod 216 is inserted is provided on the surface of the disc 215. The locking rod 216 is rotatably attached to the surface of the support box 140. A bump is fixedly attached to the surface of the locking rod 216, and a concave groove used in cooperation with the bump is provided inside the circular hole.

[0022] Preferably, the end face of the return spring 212 is fixedly connected to the inner wall of the support box 140, and the bottom of the insertion rod 211 is provided as a tapered surface.

[0023] Furthermore, the moving member 220 includes a mounting plate 221 provided in the cavity of the support box 140, a caster 222 fixedly attached to the bottom of the mounting plate 221, and a driven tooth plate 223 fixedly attached to the top of the mounting plate 221 and meshing with the transmission gear 214.

[0024] Specifically, the moving member 220 includes a convex rod 224 fixedly attached to the top of the mounting plate 221, a guide block 225 fixedly attached to the surface of the convex rod 224, and a guide groove provided inside the support box 140 and used in cooperation with the guide block 225.

[0025] Here, the cooperation between the guide block 225 and the guide groove serves to limit the position of the convex rod 224 and further improve the movement stability of the mounting plate 221.

[0026] Furthermore, a positioning hole is provided on the surface of the guide block 225, and a positioning rod 226 used in cooperation with the positioning hole is fixedly attached inside the guide groove.

[0027] Here, through the cooperation between the positioning rod 226 and the positioning hole, the positions of the guide block 225 and the convex rod 224 are limited, improving the stability when the mounting plate 221 moves up and down.

[0028] During use, when the measurement location is determined, it is necessary to push down the insertion rod 211. The bottom of the insertion rod 211 is inserted into the soil, the return spring 212 is in a stretched state, the insertion rod 211 drives the main tooth plate 213 to move downward, the main tooth plate 213 drives the transmission gear 214 to rotate, furthermore, the transmission gear 214 drives the driven tooth plate 223 to move upward, and the driven tooth plate 223 drives the mounting plate 221 and the caster 222 to move upward and be stored inside the support box 140. When the bump on the surface of the locking rod 216 moves to the top of the disc 215, the locking rod 216 is rotated to lock the bump to the top of the disc 215, restrict the position of the insertion rod 211, maintain the state where the bottom of the insertion rod 211 is inserted into the soil, fix the device by insertion, When it is necessary to move the device, first, rotate the locking rod 216 to align the bump with the concave groove. At this time, due to the elastic action of the return spring 212, the bottom of the insertion rod 211 is pulled out of the soil, the driving tooth plate 213 moves upward and drives the transmission gear 214 to rotate. Thereby, the transmission gear 214 drives the driven tooth plate 223 to move downward, and the driven tooth plate 223 drives the mounting plate 221 and the caster 222 to move downward. Further, the caster 222 extends to the bottom of the support box 140 and is used to facilitate frequent movement of the device.

[0029] As described above, through the cooperation of the insertion fixing member 210 and the moving member 220, the use stability of the distance meter 120 is improved, and the needs in the frequent moving measurement task of the distance meter 120 are satisfied. The use of the conventional distance meter 120 is unstable under bad weather conditions and it is difficult to adapt to frequent moving measurement tasks. The problem is solved, the effect of measurement stability is improved, and it is easy to operate and the working intensity is reduced.
