Description

Technical Field

[0001] This invention belongs to the field of laser indicator adjustment and calibration technology, and relates to a laser indicator shock-resistant adjustment mechanism. Background Technology

[0002] In some scenarios, such as distance measurement and aiming, existing technologies require the use of devices with two laser pointers. Errors can occur during the production and assembly of dual-head laser pointers, causing the light emitted by the two laser pointers to be non-parallel. This can lead to errors during use, making measurement or aiming inaccurate. Therefore, laser pointers with adjustment functions are particularly important. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a shock-resistant adjustment mechanism for a laser pointer that can be conveniently adjusted.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] The laser pointer anti-shock adjustment mechanism includes a housing. Inside the housing, there is a pair of parallel laser adjustment rods. A corresponding laser head one and laser head two are fixed to the outer side of the laser adjustment rods respectively. The axes of laser head one and laser head two are parallel to the length direction of the laser adjustment rods. One end of the laser adjustment rod is fixed to one end of the housing, and the other end of the laser adjustment rod is provided with an adjustment unit, which is fixed to the other end of the housing. The adjustment unit can adjust the direction of the laser adjustment rod.

[0006] Furthermore, the adjustment unit includes a fine-tuning pressure head fixed to one end of the laser adjustment rod. The fine-tuning pressure head is a pressure block with a right-angled triangular cross-section. A limit frame is provided on the side of the fine-tuning pressure head near the laser head. The limit frame is fixed to the housing. The part of the fine-tuning pressure head near the laser head is located inside the limit frame. The inclined end face of the fine-tuning pressure head is set inward and downward. Two adjacent right-angled end faces, one and two, of the fine-tuning pressure head respectively cooperate with the adjacent right-angled end faces of the limit frame. One end of a wave spring abuts against the inclined end face outside the limit frame. The other end of the wave spring abuts against the wave spring seat. The wave spring is always in a compressed state. Adjusting screws abut against the right-angled end faces one and two of the fine-tuning pressure head respectively. The adjusting screws adjust the position of the fine-tuning pressure head to realize the adjustment of the laser adjustment rod.

[0007] Furthermore, the adjusting screw includes a telescopic push rod extending toward the fine-tuning head, the end of which abuts against the right-angled end face of the corresponding fine-tuning head.

[0008] Furthermore, the adjusting screw includes an outer steel sleeve, which is fixedly connected to the housing. A pressure cap is fixedly connected to the inner side of the steel sleeve, and an adjusting nut is installed inside the pressure cap. The adjusting nut can rotate within the pressure cap. A countersunk hole with internal threads is opened on the bottom end face of the adjusting nut. The upper end of the push rod extends into the countersunk hole, and the upper end of the push rod is provided with external threads for engaging with the internal threads of the countersunk hole. The lower end of the push rod extends outside the steel sleeve.

[0009] Furthermore, the upper part of the pressure cap is provided with a stepped hole, the upper end of the adjusting nut is provided with a step that matches the stepped hole, and a fine-tuning spring is provided between the lower end of the pressure cap and the inner hole of the steel sleeve. The fine-tuning spring abuts against the lower end face of the step of the adjusting nut, and the upper end face of the adjusting nut is exposed on the outside of the housing.

[0010] Furthermore, the laser adjustment rod is fixed to the housing via a spring seat, and the laser adjustment rod between the spring seat and the fine-tuning pressure head has an elastic unit at the end near the spring seat that facilitates the adjustment of the laser adjustment rod.

[0011] Furthermore, the elastic unit includes a horizontal elastic plate that can be adjusted up and down and a vertical elastic plate that can be adjusted left and right. One end of the horizontal elastic plate is integrally set with the laser adjustment rod, and the other end of the horizontal elastic plate is integrally connected with the adapter. The adapter is a part that appears to be M-shaped in both the horizontal and vertical directions. The other end of the horizontal elastic plate is integrally connected with the middle part of the vertical M-shaped structure of the adapter. One end of the vertical elastic plate is integrally connected with another part of the laser adjustment rod, and the other end of the vertical elastic plate is integrally connected with the middle part of the horizontal M-shaped structure.

[0012] The beneficial effects of this invention are as follows:

[0013] This invention creates an adjustment rod on the side of the laser head. The laser head can be collimated by adjusting the axis of the adjustment rod through the ingenious cooperation of the adjusting nut, the limiting frame, the fine adjustment block and the wave spring. The structure is simple and easy to operate, and it does not increase the weight of the laser head much.

[0014] This invention enables the laser pointer to be protected from impacts such as vibration and collisions by using the elastic unit design of the laser pointer adjustment rod and the wave spring design. Attached Figure Description

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] As shown in the figure, a laser pointer anti-shock adjustment mechanism includes a housing 1. Inside the housing 1, a pair of parallel laser adjustment rods 2 are arranged. A laser head 3 and a laser head 4 are respectively fixed to the outer sides of the laser adjustment rods 2 by fasteners. The axes of the laser head 3 and the laser head 4 are parallel to the length direction of the laser adjustment rods 2. The laser head 3 and the laser head 4 can be set as needed; they can be the same laser head or different laser heads. One end of the laser adjustment rod 2 is fixed to one end of the housing 1 by a spring seat 11, and the other end of the laser adjustment rod 2 is provided with an adjustment unit 5, which is fixed to the other end of the housing 1.

[0029] The adjustment unit 5 includes a fine-tuning pressure head 51 fixed to one end of the laser adjustment rod 2. The fine-tuning pressure head 51 is a pressure block with an isosceles right-angled triangle cross-section. A limiting frame 52 is provided on the side of the fine-tuning pressure head 51 near the laser head. The limiting frame 52 is fixed on the housing 1. The inner frame of the limiting frame 52 is a square frame. The part of the fine-tuning pressure head 51 near the laser head is located inside the limiting frame 52. The inclined end face of the fine-tuning pressure head 51 is set inward and downward. The two adjacent right-angled end faces of the fine-tuning pressure head 51, one right-angled end face and the other right-angled end face respectively cooperate with the adjacent right-angled end faces of the limiting frame 52.

[0030] One end of a wave spring 53 abuts against the inclined end face of the outer side of the limiting frame 52, and the other end of the wave spring 53 abuts against the wave spring seat 54. The two sides of the wave spring seat 54 are inclined surfaces that cooperate with the wave spring 53. The wave spring 53 is always in a compressed state.

[0031] The wave spring 53 is designed to also buffer the laser pointer when it is subjected to vibration, collision or other impacts, thus protecting the laser pointer.

[0032] Adjusting screws 55 are respectively abutted on the first and second right-angled end faces of the fine-tuning pressure head 51. The adjusting screw 55 includes a telescopic push rod 556 extending toward the fine-tuning pressure head 51, and the end of the push rod 556 abuts against the corresponding right-angled end face of the fine-tuning pressure head 51. The limiting frame 52, adjusting screws 55, fine-tuning pressure head 51 and wave spring 53 cooperate with each other. The adjusting screw 55 and wave spring 53 press against the fine-tuning pressure head 51. The position of the fine-tuning pressure head 51 within the limiting frame 52 is adjusted by adjusting the adjusting screw 55, thereby realizing the adjustment of the laser adjusting rod 2.

[0033] The adjusting screw 55 includes an outer steel sleeve 551, which is fixedly connected to the housing 1 by threads. A pressure cap 552 is connected to the inner side of the steel sleeve 551 by threads. An adjusting nut 553 is provided inside the pressure cap 552. A stepped hole is provided on the upper part of the pressure cap 552. A step that mates with the stepped hole is provided on the upper end of the adjusting nut 553. A fine-tuning spring 555 is provided between the lower end of the pressure cap 552 and the inner hole of the steel sleeve 551. The fine-tuning spring 555 abuts against the lower end face of the step of the adjusting nut 553. In this way, the adjusting hole of the pressure cap 552 and the fine-tuning spring 555 limit the position of the adjusting nut 553. An O-ring 554 is also provided between the adjusting nut 553 and the pressure cap 552. The adjusting nut 553 can rotate within the pressure cap 552. The upper end face of the adjusting nut 553 is exposed on the outside of the housing 1, which is convenient for adjusting the adjusting nut 553 with tools.

[0034] The bottom end face of the adjusting nut 553 has a countersunk hole with internal threads. The upper end of the push rod 556 extends into the countersunk hole, and the upper end of the push rod 556 is provided with external threads for engaging with the internal threads of the countersunk hole. The lower end of the push rod 556 extends outside the steel sleeve 551. By rotating the adjusting nut 553, the rotation of the adjusting nut 553 can be converted into the linear motion of the push rod 556, thereby realizing the extension and retraction of the push rod 556, and thus adjusting the position of the fine-tuning pressure head 51.

[0035] The laser adjustment rod 2, located between the spring seat 11 and the fine-tuning pressure head 51, has an elastic unit at one end near the spring seat 11. This elastic unit includes a horizontal elastic plate 22 adjustable in the up-down direction and a vertical elastic plate 23 adjustable in the left-right direction. One end of the horizontal elastic plate 22 is integrally formed with the laser adjustment rod 2, and the other end is integrally connected to an adapter 21. The adapter 21 is a component that appears to have an M-shape structure both horizontally and vertically. The other end of the horizontal elastic plate 22 is integrally connected to the middle of the vertical M-shape structure of the adapter 21. One end of the vertical elastic plate 23 is integrally connected to another part of the laser adjustment rod 2, and the other end is integrally connected to the middle of the horizontal M-shape structure. This ingenious design achieves elastic adjustment of the laser adjustment rod 2 in both the horizontal and vertical directions.

[0036] The elastic unit can also buffer the laser pointer when it is subjected to vibration, collision or other impacts, thus protecting the laser pointer.

[0037] The working principle of this invention:

[0038] Depending on the different assembly of laser head 3 and laser head 4, the collimation of laser head 3 and laser head 4 can be adjusted by adjusting the four adjusting nuts 553. Alternatively, this device can be used in conjunction with a corresponding testing instrument to adjust the collimation of laser head 3 and laser head 4 by adjusting the four adjusting nuts 553.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
