Description

[Technical Field]

[0001] This utility model relates to a laser emitter. [Background Technology]

[0002] A laser emitter is a device that emits laser light. Utilizing the properties of laser light, it can perform functions such as measurement, ranging, detection, warning, and weapon aiming. Current laser emitters generally consist of a lens section, a module housing, a battery section, and a laser module within the module housing. To ensure the accuracy of laser measurement and ranging functions, the coaxiality of the laser module and the module housing needs to be adjusted. Higher coaxiality results in higher accuracy of laser measurement.

[0003] Chinese Patent Publication No. (CN222691090U) discloses a finely adjustable laser emitter with a scale. This laser emitter uses a fine-tuning rod to push the module positioning sleeve, and utilizes the deformation of the positioning rubber ring to adjust the coaxiality between the laser module and the module sleeve, thereby ensuring the accuracy of the laser emission angle. This utility model provides a new laser emitter that differs from existing technologies, achieving convenient adjustment of the laser module and ensuring accurate laser emission angle or position. [Utility Model Content]

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a laser emitter with a simple structure. This laser emitter allows for convenient and rapid adjustment of the coaxiality of the laser module and the module sleeve, ensuring precise laser emission angle or position, thereby improving the accuracy of laser measurement, ranging, and other functions.

[0005] This utility model is achieved through the following technical solution:

[0006] A laser emitter includes a battery unit, a module sleeve, a lens unit, and a laser module disposed within the module sleeve. The module sleeve has a first arc surface, and one end of the laser module has a second arc surface that movably engages with the first arc surface. The side wall of the module sleeve has an adjustment element that can push the laser module to move and adjust the coaxiality between the laser module and the module sleeve. A second elastic element that can deform in the radial direction when the laser module is adjusted is disposed between the laser module and the inner side wall of the module sleeve. The other end of the laser module also has a first elastic element that abuts against it and can deform in the axial direction when the laser module is adjusted.

[0007] The module sleeve includes a cylindrical shell, a front seat connected to the front end of the shell, a first arc surface disposed on the front seat, a rear seat connected to the rear end of the shell, and a first elastic element with one end abutting against the laser module and the other end abutting against the rear seat.

[0008] The first elastic element is a spring or an elastic rubber ring.

[0009] The rear seat is provided with a positioning groove for positioning the first elastic element.

[0010] The adjustment element includes a knob exposed outside the module sleeve, and an adjustment rod connected to the knob that can push against the side wall of the laser module.

[0011] The second elastic element is an arc-shaped spring sheet, with the apex of the spring sheet abutting against the side wall of the laser module and both ends of the spring sheet abutting against the inner side wall of the module sleeve.

[0012] The inner wall of the module sleeve is provided with a limiting groove along the axial direction, and the two ends of the spring sheet are inserted into the limiting groove.

[0013] The adjustment element is at least two and is arranged at intervals along the circumferential direction on the module sleeve.

[0014] The battery unit is connected to the rear end of the module sleeve, and one end of the first elastic element abuts against the laser module, while the other end abuts against the battery unit.

[0015] The battery section is sleeved and connected to the module sleeve, and a first sealing ring is provided between the two. The lens section is sleeved and connected to the front end of the module sleeve, and a second sealing ring is provided between the two.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. In this invention, the second arc surface on the laser module mates with the first arc surface on the module sleeve. When the adjusting element pushes the laser module, the laser module and the module sleeve can move relative to each other at the point where the first and second arc surfaces meet, thereby adjusting the position of the laser module. During this process, the second elastic element deforms in the radial direction, and the first elastic element deforms in the axial direction, ensuring that the laser module is effectively maintained after adjustment. The entire adjustment operation is convenient and quick, and also improves structural stability.

[0018] 2. The inner wall of the module sleeve of this utility model is provided with a limiting groove along the axial direction, and the second elastic element is set in the limiting groove, which can be easily assembled. When adjusting the top-pushing laser module, the second elastic element will not shift, ensuring the stability of the structure.

[0019] 3. This utility model has a simple structure, is easy to adjust, and has excellent seismic resistance, making it suitable for widespread application. [Attached Image Description]

Detailed Implementation Methods

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1 to 6 As shown, a laser emitter includes a battery unit 3, a module sleeve 11, a lens unit 2, and a laser module 12 disposed within the module sleeve 11. The battery unit 3 is sleeved to the rear end of the module sleeve 11, with a first sealing ring 5 positioned between them. The lens unit 2 is sleeved to the front end of the module sleeve 11, with a second sealing ring 6 positioned between them. The laser emitted by the laser module 12 is projected through the lens unit 2 and can be used for measurement, ranging, positioning, and other applications. The first and second sealing rings 5 ​​and 6 also provide the laser emitter with waterproof functionality.

[0028] like Figures 3 to 5 As shown, the module sleeve 11 is provided with a first arc surface 13, and one end of the laser module 12 is provided with a second arc surface 14 that can be movably engaged with the first arc surface 13. The side wall of the module sleeve 11 is provided with an adjustment element 16 that can push the laser module 12 to move and adjust the coaxiality between the laser module 12 and the module sleeve 11. A second elastic element 17 that can deform in the radial direction when the laser module 12 is adjusted is provided between the laser module 12 and the inner side wall of the module sleeve 11. The other end of the laser module 12 is also provided with a first elastic element 15 that abuts against it and can deform in the axial direction when the laser module 12 is adjusted. The second arc surface 14 on the laser module 12 cooperates with the first arc surface 13 on the module sleeve 11, so that when the adjusting element 16 pushes the laser module 12, the laser module 12 can swing relative to the module sleeve 11, thereby adjusting the position of the laser module 12. During this process, the second elastic element 17 deforms in the radial direction and the first elastic element 15 deforms in the axial direction, which enables the laser module 12 to be effectively maintained after being adjusted into position. The entire adjustment operation is convenient and quick, and it is also vibration resistant. During use or transportation, the positioning will not be affected by vibration, thus improving the structural stability.

[0029] like Figures 3 to 6As shown, the module sleeve 11 includes a cylindrical housing 111. A front seat 112 is connected to the front end of the housing 111. A first arc surface 13 is disposed on the front seat 112. A rear seat 113 is connected to the rear end of the housing 111. One end of the first elastic element 15 abuts against the laser module 12, and the other end abuts against the rear seat 113. Both the front seat 112 and the rear seat 113 can be detachably connected to the housing 111 using a threaded structure, facilitating the assembly of the laser module 12. Alternatively, one end of the first elastic element 15 can abut against the laser module 12, and the other end against the battery section 3, as long as the first elastic element 15 can undergo elastic deformation in the axial direction when the adjusting element 16 pushes the laser module 12. This deformation allows the laser module 12 to maintain its position when adjusted to a suitable location.

[0030] like Figure 3 and Figure 4 As shown, in this embodiment, the first elastic element 15 is a spring. Of course, the first elastic element can also be an elastic rubber ring.

[0031] like Figure 4 As shown, the rear seat 113 is provided with a positioning groove 114 that can position the first elastic element 15, so as to prevent the rear end of the first elastic element 15 from shifting in the radial direction when it deforms.

[0032] like Figure 3 He Ru Figure 4 As shown, at least two adjusting elements 16 are spaced apart circumferentially on the module sleeve 11. Each adjusting element 16 includes a knob 161 exposed on the module sleeve 11, and an adjusting rod 162 connected to the knob 161 that can push the side wall of the laser module 12. By rotating the two knobs 161, the adjusting rod 162 can be used to push the laser module 12, causing the laser module 12 to slide relative to the front seat 112, thereby adjusting the coaxiality of the laser module 12 and the module sleeve 11, so that the laser emission direction is in the desired direction. Of course, the adjusting element 16 can also be a screw structure, in which rotating the screw pushes the side wall of the laser module 12, causing the laser module 12 to move relative to the module sleeve 11.

[0033] like Figure 3 and Figure 4 As shown, the second elastic element 17 is an arc-shaped spring sheet. The apex of the spring sheet abuts against the side wall of the laser module 12, and both ends of the spring sheet abut against the inner side wall of the module sleeve 11. The inner side wall of the module sleeve 11 is provided with a limiting groove 18 along the axial direction. The two ends of the spring sheet are inserted into the limiting groove 18, which can facilitate assembly. The second elastic element 17 will not shift when adjusting and pushing the laser module 12, ensuring the stability of the structure.

[0034] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
