However, this laser emitter has a long structure and large volume, making it unsuitable for some special operating environments.

[0004] Therefore, this utility model was created based on the above-mentioned shortcomings. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a simple and compact dual-channel laser emitter.

[0006] This utility model is achieved through the following technical solution:

[0007] A dual-channel compact laser emitter includes a base with a first channel and a second channel spaced apart from each other along its left-right direction. A laser emitting module is housed within the first channel. A first front sealing cover is located at the front end of the first channel, and a first rear sealing cover is located at the rear end of the first channel. The first front and rear sealing covers enclose the laser emitting module within the first channel. A laser emission outlet is located on the first front sealing cover. A battery assembly that powers the laser emitting module is housed within the second channel. A second front sealing cover is located at the front end of the second channel, and a second rear sealing cover is located at the rear end of the second channel. The second front and rear sealing covers enclose the battery assembly within the second channel. The base also has a connecting channel linking the first and second channels, through which a wire for connecting the battery assembly and the laser emitting module passes.

[0008] At least one of the first front sealing cover and the first rear sealing cover is detachably connected to the base, and at least one of the second front sealing cover and the second rear sealing cover is detachably connected to the base.

[0009] The second rear sealing cover is connected to a switch button for turning on laser emission. The switch button is located on one side of the base, and the laser emission outlet is located on the other side of the base.

[0010] The battery assembly includes a battery body, a negative electrode spring, and a PCB board. The PCB board is fixed to the bottom of the second front cover. The wires are connected to the PCB board. The negative electrode spring is disposed between the battery body and the PCB board. A positioning ring is also provided between the PCB board and the battery body, which is threaded to the second front cover and positions the battery body. The negative electrode spring passes through the positioning ring.

[0011] The connecting channel includes a main channel extending along the front-rear direction of the base and located between the first channel and the second channel. One end of the base is provided with a first auxiliary channel connecting the main channel and the first channel, and the other end of the base is provided with a second auxiliary channel connecting the main channel and the second channel. The wire passes through the second auxiliary channel, the main channel and the first auxiliary channel. One end of the wire is connected to the laser emitting module near the first rear sealing cover, and the other end is connected to the battery assembly near the second front sealing cover.

[0012] The upper surface of the base is provided with a first inclined hole that intersects with the main channel and enters the first channel. The first auxiliary channel is formed by drilling the first inclined hole. The upper surface of the base is also provided with a second inclined hole that intersects with the main channel and enters the second channel. The second auxiliary channel is formed by drilling the second inclined hole.

[0013] The second front sealing cover is threadedly connected to the base via a threaded connection portion thereon. A through hole is provided on the side wall of the threaded connection portion for the wire to pass through. When the second front sealing cover is tightened with the base, the through hole is opposite to the second auxiliary channel to allow the wire to pass through.

[0014] The first channel sidewall is provided with a groove extending in the front-rear direction. An arc-shaped spring sheet is provided in the groove. The arc apex of the spring sheet abuts against the laser emitting module.

[0032] The present invention will be further described below with reference to the accompanying drawings:

[0033] like Figures 1 to 11 As shown, a dual-channel compact laser emitter includes a base 1, on which a first channel 11 and a second channel 12 are spaced apart along a left-right direction. A laser emitting module 2 is housed within the first channel 11. The front end of the first channel 11 is sealed by a first front sealing cover 31, and the rear end is sealed by a first rear sealing cover 41, thus securely encapsulating the laser emitting module 2 within the first channel 11. A laser emission outlet 5 is provided on the first front sealing cover 31 for laser beam emission. The second channel 12 houses a battery assembly 6 that powers the laser emitting module 2. The front end of the second channel 12 is sealed by a second front sealing cover 32, and the rear end is sealed by a second rear sealing cover 42, ensuring reliable fixation of the battery assembly 6. By arranging the battery assembly 6 and the laser emitting module 2 spaced apart left-right, the traditional structural layout of the battery assembly and laser emitting module is changed, effectively shortening the overall length of the laser emitter, reducing its structural volume, and improving portability and installation flexibility, making it particularly suitable for environments with stringent requirements on laser emitter length. The base 1 is also provided with a connecting channel 13 that connects the first channel 11 and the second channel 12. A wire 7 connecting the battery assembly 6 and the laser emitting module 2 is run through the channel to ensure that the battery assembly 6 and the laser emitting module 2 can be powered normally when they are set at left and right intervals.

[0034] like Figure 1 , Figure 2 as well as Figures 7 to 9As shown, for ease of assembly and maintenance, at least one of the first front sealing cover 31 and the first rear sealing cover 41 is detachably connected to the base 1. Similarly, at least one of the second front sealing cover 32 and the second rear sealing cover 42 is also detachably connected to the base 1. In this embodiment, the first front sealing cover 31, the first rear sealing cover 41, the second front sealing cover 32, and the second rear sealing cover 42 are all detachable structures and are connected to the base 1 by threads. A switch button 43 for controlling laser emission is connected to the second rear sealing cover 42, which is located on one side of the base 1, while the laser emission outlet 5 is located on the other side of the base 1, thus separating the operation from the light emission direction for easy control during use.

[0035] like Figure 6 , Figure 7 , Figure 8 , Figure 10 and Figure 11 As shown, the connecting channel 13 specifically includes a main channel 131 extending along the front-rear direction of the base 1 and located between the first channel 11 and the second channel 12. One end of the base 1 has a first auxiliary channel 132 connecting the main channel 131 and the first channel 11, and the other end has a second auxiliary channel 133 connecting the main channel 131 and the second channel 12. A wire 7 is run through the second auxiliary channel 133, the main channel 131, and the first auxiliary channel 132. One end of the wire 7 is connected to the side of the laser emitting module 2 near the first rear sealing cover 41, and the other end is connected to the side of the battery assembly 6 near the second front sealing cover 32. This ensures a reasonable wiring path when the laser emission outlet 5 and the switch button 43 are located on opposite sides of the base 1, which is beneficial for the efficient use of internal space. The first auxiliary channel 132 is formed by a first oblique hole 101 drilled on the upper surface of the base 1, intersecting with the main channel 131 and extending into the interior of the first channel 11; the second auxiliary channel 133 is formed by a second oblique hole 102 drilled on the upper surface of the base 1, intersecting with the main channel 131 and extending into the interior of the second channel 12. This structure facilitates the processing and shaping of the first auxiliary channel 132 and the second auxiliary channel 133. At the same time, when threading the wire 7, tools can be used to reach into the first oblique hole 101 and the second oblique hole 102 to hook the wire 7, ensuring that the wire 7 is threaded smoothly.

[0036] like Figure 7 As shown, the second front sealing cover 32 is threadedly connected to the base 1 via a threaded connection portion 321. The side wall of the threaded connection portion 321 has a through hole 322 for the wire 7 to pass through. When the second front sealing cover 32 is tightened onto the base 1, the through hole 322 is aligned with the second auxiliary channel 133, allowing the wire 7 to pass through smoothly, while ensuring the sealing performance and structural compactness of the second front sealing cover 32.

[0037] like Figure 1 and Figure 7As shown, further, the side wall of the first channel 11 is provided with a groove 111 extending in the front-back direction. An arc-shaped spring sheet 112 is provided in the groove 111, and its arc top abuts against the laser emitting module 2. The base 1 is provided above the first channel 11 with a first adjusting screw 113 that can push the laser emitting module 2. The base 1 is provided on the side away from the second rear sealing cover 42 with a second adjusting screw 114 that can push the laser emitting module 2. The front of the laser emitting module 2 is provided with a protruding protrusion 21. A positioning rubber ring 22 is connected to the protrusion 21 and sleeved on the laser emitting module 2. The laser emitting module 2 is provided with a fixing ring 23 that can cooperate with the protrusion 21 to clamp the positioning rubber ring 22. The outer peripheral surface of the positioning rubber ring 22 abuts against the inner side wall of the first channel 11. This structure allows the laser emitting module 2 to be finely adjusted in position under the combined action of the spring plate 112 and the adjusting screw, which helps optimize the beam emission accuracy and stability. Specifically, by rotating the first adjusting screw 113 and the second adjusting screw 114, the elastic force of the spring plate 112 can be overcome to push the laser emitting module 2 to move. During the movement, the spring plate 112 and the positioning rubber ring 22 elastically deform to provide compensation, so that the laser beam can be adjusted to a suitable emission direction and the position of the laser emitting module 2 can be kept firmly fixed. Of course, the first adjusting screw 113 can also be set on the base 1 and below the first channel 11, or the first adjusting screw 113 can be set on the base 1 and both above and below the first channel 11, so as to facilitate fine adjustment of the laser emitting module 2.

[0038] like Figure 12 and Figure 13 As shown, in this embodiment, the battery assembly 6 includes a battery body 61, a negative electrode spring 62, and a PCB board 63. The PCB board 63 is fixed to the bottom of the second front sealing cover 32. Wires 7 are connected to the PCB board 63. The negative electrode spring 62 is disposed between the battery body 61 and the PCB board 63. A positioning ring 34 is also provided between the PCB board 63 and the battery body 61, which is threadedly connected to the second front sealing cover 32 and positions the battery body 61. The negative electrode spring 62 passes through the positioning ring 34. In this structure, the PCB board 63 is fixed to the bottom of the second front sealing cover 32, resulting in a compact structure and secure installation. In this embodiment, the PCB board 63 is fixed inside the second front sealing cover 32 using two screws 35.

[0039] like Figures 1 to 5As shown, a clamping mechanism 8 for clamping and mounting the base 1 to an external bracket is also connected to the base 1. The clamping mechanism 8 includes a fixed clamping seat 81 connected to the base 1, and a movable clamping seat 82 that can open and close relative to the fixed clamping seat 81, forming a clamping opening 83 for clamping and fixing. An adjusting rod 84 that passes laterally through the movable clamping seat 82 is fixedly connected inside the fixed clamping seat 81. An adjusting handle 85 is threaded to the outer end of the adjusting rod 84. Rotating the adjusting handle 85 by hand can push the clamping seat 82 to move, thereby adjusting the tightness of the clamping opening 83. The outer end of the adjusting handle 85 is provided with an internal hexagonal groove 88, which facilitates adjustment using standard tools, further improving the convenience and reliability of operation. A spring 86 is provided between the movable clamping seat 82 and the fixed clamping seat 81, so that the two maintain a certain degree of opening when not locked, ensuring that the movable clamping seat 82 is in a fixed position that cannot move freely, facilitating quick installation and removal. The base 1 is provided with a mounting groove 115, and the fixed clamping seat 81 is provided with a locking strip 87 that engages with the mounting groove 115. The two are detachably connected by a screw 9 that passes vertically through the locking strip 87, which enhances the stability of the connection between the clamping mechanism and the base.

[0040] 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.
