DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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.

[0028] This embodiment provides a laser fixing bracket, which fixes the laser and solves the problem of the focus cap being accidentally touched.

[0029] like Figure 2 and Figure 3 As shown, it includes a positioning ring 2 for the laser 10 to pass through, wherein a threaded hole 22 arranged radially along the positioning ring 2 is provided on the side wall of the positioning ring 2, wherein a push bolt 23 is connected to the inner thread of the threaded hole 22.

[0030] When the laser 10 passes through the positioning ring 2 and reaches a suitable position, the push bolt 23 is rotated so that the end wall of the push bolt 23 abuts against the side wall of the laser 10, thereby fixing the laser 10.

[0031] In order to improve the fixing effect of the laser 10, in this embodiment, as Figure 3 As described above, two groups of push bolts 23 are provided and are symmetrical about the vertical plane where the central axis of the laser 10 is located. The two push bolts 23 clamp the laser 10 at the same time to improve the stability of the laser 10.

[0032] In order to prevent the focusing cap 102 on the laser 10 from being accidentally touched, in this embodiment, Figure 2 and Figure 4 As shown, it also includes a protective retaining ring 4 that slides axially along the positioning ring 2. When the laser 10 is fixed inside the positioning ring 2 by the pushing bolt 23, the light is first adjusted by the focusing cap 102, and then the protective retaining ring 4 is pushed to the outside of the focusing cap 102 to protect the focusing cap 102, thereby preventing outsiders from accidentally touching the focusing cap 102.

[0033] In order to realize the installation of the protective retaining ring 4, in this embodiment, as Figure 2 and Figure 4 As shown, the positioning ring 2 is provided with a guide groove 21 arranged along the axial direction of the positioning ring 2, and a guide plate 3 is provided in the guide groove 21 and is slidably connected along the axial direction of the positioning ring 2. It is worth noting that the cross-section of the guide groove 21 is arc-shaped, and the side wall of the guide plate 3 abuts against the inner wall of the guide groove 21 to limit the rotation of the guide plate 3. Specifically, the protective retaining ring 4 can be detachably installed on the guide plate 3.

[0034] It is worth mentioning here that due to long-term use, the protective retaining ring 4 has a greater chance of contacting the laser 10, which can easily cause damage to the protective retaining ring 4. At this time, the detachable connection between the protective retaining ring 4 and the guide plate 3 facilitates the replacement of the protective retaining ring 4.

[0035] In order to realize the detachable installation of the protective retaining ring 4 and the guide plate 3, in this embodiment, as shown in FIG. Figure 2 , Figure 4 and Figure 5 As shown, the guide plate 3 and the protective retaining ring 4 are fixed by using a positioning mechanism 7. Specifically, the positioning mechanism 7 includes a positioning bolt 71, wherein the positioning bolt 71 passes through the guide plate 3 and is threadedly connected to the protective retaining ring 4, thereby fixing the protective retaining ring 4.

[0036] During the fixing process of the protective retaining ring 4, the positioning bolt 71 needs to be rotated. At this time, the positioning bolt 71 easily drives the protective retaining ring 4 to rotate synchronously with the positioning bolt 71. In order to solve this problem, in this embodiment, as shown in FIG. Figure 5 As shown, a positioning block 41 is fixedly provided on the peripheral wall of the protective retaining ring 4, and a positioning groove 31 for inserting the positioning block 41 is provided on the guide plate 3. The side wall of the positioning block 41 abuts against the inner wall of the positioning groove 31 to limit the rotation of the positioning block 41. Specifically, in the present embodiment, the interface of the positioning block 41 is a regular hexagon, and the shape of the positioning groove 31 is adapted to the positioning block 41. When fixing the protective retaining ring 4, the positioning bolt 71 is threadedly connected to the positioning block 41.

[0037] In order to facilitate accurate adjustment of the position of the protective retaining ring 4, in this embodiment, Figure 2 and Figure 4 As shown, a positioning plate 24 is fixedly provided on the side wall of the positioning ring 2, and also includes a first tension spring 5, one end of the first tension spring 5 is fixedly connected to the positioning plate 24, and the other end of the first tension spring 5 is fixedly connected to the guide plate 3, wherein a limiting assembly 6 is also provided on the protective retaining ring 4 and radially arranged along the protective retaining ring 4, wherein the limiting assembly 6 can switch between a limiting state and an unlocking state.

[0038] When no restriction is imposed on the limiting component 6 , part of the limiting component 6 extends to the inner side of the protective retaining ring 4 to limit the insertion of the laser 10 .

[0039] Through the above arrangement, during the installation of the laser 10, the position of the push bolt 23 is first adjusted to prevent the push bolt 23 from restricting the laser 10 from being inserted into the positioning ring 2. Figure 6As shown, at this time, the end wall of the emitting end 101 of the laser 10 abuts against the limiting assembly 6. With the insertion of the laser 10, under the action of the limiting assembly 6, the protective retaining ring 4 moves to the side away from the positioning ring 2 and stretches the first tension spring 5, and then the push bolt 23 is rotated to make the end wall of the push bolt 23 abut against the peripheral wall of the laser 10, thereby fixing the laser 10 to prevent the laser 10 from retreating.

[0040] At this time, the limit assembly 6 can be switched to the unlocked state, so that the protective retaining ring 4 can retreat under the action of the first tension spring 5. At this time, the focusing cap 102 is exposed, and the light of the laser 10 can be adjusted by the focusing cap 102. After the adjustment is completed, the focusing cap 102 is blocked by moving the protective retaining ring 4, and the limit assembly 6 is restored to the limited state and abuts against the end wall of the transmitting end 101, thereby fixing the position of the protective retaining ring 4.

[0041] Specifically, in this embodiment, Figure 6 As shown, the limit assembly 6 includes a limit rod 61 and a second tension spring 62. A through hole 42 is provided on the side wall of the protective retaining ring 4 along the radial direction of the protective retaining ring 4. The limit rod 61 penetrates into the through hole 42, and the second tension spring 62 is sleeved on the outside of the limit rod 61. One end of the second tension spring 62 is fixedly connected to the outer wall of the protective retaining ring 4, and the other end of the second tension spring 62 is fixedly connected to the limit rod 61. In the limited state, the end of the limit rod 61 extends to the inside of the protective retaining ring 4; in the unlocked state, the limit rod 61 is retracted into the through hole 42 to avoid abutting against the laser 10 and affecting the movement of the protective retaining ring 4.

[0042] In order to prevent the limiting rod 61 from being excessively stretched so that the limiting rod 61 is pulled to the outside of the through hole 42, in this embodiment, as shown in FIG. Figure 6 As shown, the side wall of the through hole 42 is provided with a limiting groove 421 radially arranged along the protective retaining ring 4, and the side wall of the limiting rod 61 is fixedly provided with a limiting protrusion 611. When the limiting rod 61 is retracted into the through hole 42, the limiting protrusion 611 slides into the limiting groove 421, and the limiting protrusion 611 abuts against the bottom wall of the limiting groove 421, thereby limiting the transition stretching of the limiting rod 61.

[0043] It is worth noting that the limiting protrusion 611 is located at a side away from the positioning ring 2 to prevent the limiting protrusion 611 from contacting the laser 10 .

[0044] In order to realize the installation of the first tension spring 5, in this embodiment, as Figure 4 As shown, the positioning plate 24 is provided with a plug-in slot 241 opening upward, wherein one end of the first tension spring 5 is plugged into the plug-in slot 241 and fixed to the positioning plate 24 , and the other end of the first tension spring 5 is fixedly mounted on the guide plate 3 by a positioning bolt 71 .

[0045] In order to prevent the first tension spring 5 near the side of the protective retaining ring 4 from being easily entangled, in this embodiment, as shown in FIG. Figure 4 As shown, an L-shaped protective sheet metal 72 is also included, wherein the bent edge of the protective sheet metal 72 shields the end of the first tension spring 5 , and the protective sheet metal 72 is fixed to the guide plate 3 by a positioning bolt 71 .

[0046] In order to be able to adjust the angle of the positioning ring 2, a positioning seat is also included for installing the positioning ring 2. The positioning seat and the positioning ring 2 can be connected by a ball pin so that the positioning ring 2 can rotate. The structure for adjusting the angle of the positioning ring 2 is well known to people in this field, and the specific structure of the positioning seat is not described here.

[0047] In order to facilitate the installation of the positioning ring 2 and the positioning seat, in this embodiment, as shown in FIG. Figure 4 and Figure 7 As shown, a connecting seat 8 is also installed on the positioning seat, wherein the connecting seat 8 includes a connecting rod 81 fixed on the positioning seat, and a threaded tube 83 and a connecting end cap 82 are fixedly provided at the end of the connecting rod 81, wherein the interface of the connecting end cap 82 is T-shaped, and the outer side of the threaded tube 83 is threadedly connected with a locking nut 84, and the outer wall of the positioning ring 2 is fixedly provided with a positioning sheet metal 25, and the positioning sheet metal 25 is provided with a U-shaped connecting groove 251, and one end of the connecting groove 251 is opened outward. When the positioning ring 2 is installed, the connecting end cap 82 is inserted into the connecting groove 251 and the bottom wall of the connecting end cap 82 is abutted against the positioning sheet metal 25, and the locking nut 84 is rotated to clamp the positioning sheet metal 25 using the locking nut 84 and the connecting end cap 82, thereby realizing the rapid installation of the positioning ring 2.

[0048] When the positioning ring 2 is removed from the positioning seat, it is only necessary to rotate the locking nut 84 to release the clamping of the locking nut 84 and the connecting end cap 82 on the positioning sheet metal 25. The disassembly action can be completed without rotating the positioning ring 2; when the locking nut 84 and the connecting end cap 82 release the clamping of the positioning sheet metal 25, the angle of the positioning ring 2 can be adjusted by rotating the positioning ring 2, and then the locking nut 84 is used to lock the positioning ring 2.

[0049] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
