Description

Technical Field

[0001] The utility model relates to the technical field of measuring equipment, in particular to an L-shaped right-angle prism. Background Art

[0002] L-shaped right-angle prism is a geodetic prism used to monitor building settlement. The principle is to emit a light beam to the target through a laser or infrared transmitter, and then reflect it back through a reflector or a reflective prism, so that the three-dimensional coordinates of the target can be calculated.

[0003] The utility model patent application document with publication number "CN209728307U" discloses a rainproof right-angle prism, which is mainly composed of an L-shaped prism frame, a prism shell, a corner cube prism and fixing screws. This technical solution has the advantages of easy installation and maintenance and dust and rain resistance.

[0004] The rainproof right-angle prism disclosed in the above document has the following defects: when installing the right-angle prism, generally a detection hole is first opened at the place to be detected, and then the expansion sleeve is placed inside the hole, and then the bolt is passed through the installation of the right-angle prism and screwed into the inside of the expansion sleeve, so that the expansion sleeve expands and squeezes the detection hole, thereby achieving the fixed installation of the right-angle prism. However, during use, the right-angle prism cannot adjust its own height, so that the right-angle prism cannot calculate different heights of the same object, and its practicality is poor.

[0005] It can be seen from this that the existing right-angle prism does not have a structure for adjusting the height of the corner cube prism, and it is necessary to improve the existing shortcomings and provide an L-shaped right-angle prism. Utility Model Content

[0008] The utility model is an L-shaped right-angle prism, comprising an L-shaped prism frame, one end of the L-shaped prism frame is provided with a first threaded hole, the other end of the L-shaped prism frame is provided with a second threaded hole, the internal thread of the first threaded hole is connected with a first hand-tightening bolt, one end of the first hand-tightening bolt is installed with a prism shell, a corner cone prism is installed inside the prism shell, the outer surface of the L-shaped prism frame is provided with four clips, the interior of the clip is provided with a lifting assembly, the upper surface of the L-shaped prism frame is provided with a mounting hole, the interior of the L-shaped prism frame is provided with a sliding groove, one end of the sliding groove extends to the interior of the mounting hole, and the interior of the sliding groove is provided with a locking assembly.

[0009] Furthermore, the lifting assembly includes a first connecting rod, the outer surface of which is provided with an external thread, one end of which is provided with a third threaded hole, the internal thread of the third threaded hole is connected to a one-way screw, and one end of the one-way screw is provided with a second connecting rod.

[0010] Furthermore, the locking assembly includes a locking block, which is slidably connected to the inside of the slide groove, and the inner thread of the second threaded hole is connected to a second hand-tightened bolt, and the locking block is installed at one end of the second hand-tightened bolt.

[0011] Furthermore, one end of the locking block is provided with a plurality of elastic anti-slip strips.

[0012] Furthermore, a mounting groove is formed at one end of the L-shaped prism frame, an anti-loosening washer is installed inside the mounting groove, and an outer surface of the anti-loosening washer abuts against an outer surface of the first hand-tightening bolt.

[0013] Furthermore, the inner surfaces of the four clips are provided with anti-slip stripes.

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model can adjust the height of the right-angle prism by means of the lifting assembly, which is convenient for the right-angle prism to calculate different heights of the same object. At the same time, the right-angle prism can be fixed on the lifting assembly by means of the locking assembly, which prevents the position of the right-angle prism from moving during use, thereby achieving a better fixing effect.

[0016] (2) The utility model can increase the friction between the first hand-tightened bolt and the L-shaped prism frame by providing an anti-loosening washer, thereby preventing the first hand-tightened bolt from loosening during use, causing the angle between the prism shell and the prism to change, thereby achieving a better practical effect.

DETAILED DESCRIPTION

[0028] 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.

[0029] See also Figure 1 - Figure 7 As shown, the utility model is an L-shaped right-angle prism, comprising an L-shaped prism frame 1, a first threaded hole is provided at one end of the L-shaped prism frame 1, a second threaded hole is provided at the other end of the L-shaped prism frame 1, a first hand-tightened bolt 2 is connected to the inner thread of the first threaded hole, a prism shell 3 is installed at one end of the first hand-tightened bolt 2, a corner cube prism 4 is installed inside the prism shell 3, four clips 101 are provided on the outer surface of the L-shaped prism frame 1, a lifting assembly 5 is provided inside the clip 101, a mounting hole 102 is provided on the upper surface of the L-shaped prism frame 1, a slide groove 103 is provided inside the L-shaped prism frame 1, one end of the slide groove 103 extends to the inside of the mounting hole 102, and a locking assembly 6 is provided inside the slide groove 103;

[0030] The lifting assembly 5 includes a first connecting rod 501, an outer surface of which is provided with an external thread 502, one end of which is provided with a third threaded hole 503, the inner thread of the third threaded hole 503 is connected with a one-way screw rod 504, and one end of the one-way screw rod 504 is provided with a second connecting rod 505;

[0031] When installing the L-shaped right-angle prism, first open a detection hole at the place to be detected, then put the expansion sleeve into the hole, then take out the first connecting rod 501 and the second connecting rod 505 from the corresponding clamps 101, and complete the fixed installation between the first connecting rod 501 and the second connecting rod 505 by installing the one-way screw 504 into the third threaded hole 503. At this time, the first connecting rod 501 and the second connecting rod 505 are combined to form a sliding rod, and the first connecting rod 501 is installed into the expansion sleeve through the external thread 502, so that the expansion sleeve expands and squeezes the detection hole, and the first connecting rod 501 is fixed at the same time. After fixing, the L-shaped prism frame 1 is sleeved on the outer surface of the sliding rod through the installation hole 102, and the L-shaped prism frame 1 is pulled upward or downward to slide upward or downward along the axis to achieve the effect of adjusting the height of the L-shaped right-angle prism;

[0032] The locking assembly 6 includes a locking block 601, which is slidably connected to the inside of the slide groove 103, and the second threaded hole is internally threadedly connected with a second hand-tightening bolt 602, and one end of the second hand-tightening bolt 602 is installed with the locking block 601;

[0033] After the height of the L-shaped right-angle prism is adjusted, the second hand-tightening bolt 602 is rotated so that the second hand-tightening bolt 602 moves axially in the sliding groove 103 with the second threaded hole as the center. When the second hand-tightening bolt 602 is rotated clockwise, the second hand-tightening bolt 602 will push the locking block 601 to move toward the end close to the sliding rod, so that the locking block 601 is close to the outer surface of the sliding rod, thereby achieving the effect of fixing the position of the L-shaped prism frame 1. When the second hand-tightening bolt 602 is rotated counterclockwise, the second hand-tightening bolt 602 will drive the locking block 601 to move toward the end away from the sliding rod, so that the locking block 601 cancels the extrusion of the outer surface of the sliding rod, thereby canceling the effect of fixing the position of the L-shaped prism frame 1;

[0034] One end of the locking block 601 is provided with a plurality of elastic anti-slip strips 603;

[0035] The elastic anti-slip strip 603 can increase the friction between the locking block 601 and the slide rod, so that the L-shaped prism frame 1 is not prone to sliding, achieving a better locking effect;

[0036] An installation groove 104 is formed at one end of the L-shaped prism frame 1, and an anti-loosening washer 7 is installed inside the installation groove 104, and the outer surface of the anti-loosening washer 7 abuts against the outer surface of the first hand-tightening bolt 2;

[0037] The anti-loosening washer 7 can increase the friction between the first hand-tightening bolt 2 and the L-shaped prism frame 1, thereby preventing the first hand-tightening bolt 2 from loosening during use, so that the angle between the prism shell 3 and the corner cube prism 4 changes, thereby achieving a better practical effect.

[0038] The inner surfaces of the four clips 101 are provided with anti-slip stripes;

[0039] The anti-slip stripes on the inner surface of the clip 101 can increase the friction between the clip 101 and the first connecting rod 501 and the second connecting rod 505, thereby preventing the first connecting rod 501 and the second connecting rod 505 from detaching from the inside of the clip 101 when not in use, thereby achieving a better fixing effect.
