Description

Technical Field

[0001] The utility model belongs to the field of laser technology, and in particular relates to a fine-tunable laser transmitter with scale. Background Art

[0002] Laser is light produced by stimulated radiation from atoms. When the electrons in atoms absorb energy and jump from low energy level to high energy level, and then fall back from high energy level to low energy level, the released energy is released in the form of photons. The stimulated light beam is laser. The optical properties of laser photons are highly consistent, so laser has better monochromaticity, directionality and higher brightness than ordinary light sources.

[0003] A laser transmitter is a device that can emit lasers. The characteristics of lasers can be used to achieve functions such as measurement, ranging, detection, warning, and weapon aiming.

[0004] At present, conventional laser transmitters only have the function of emitting lasers, but cannot accurately send lasers to the target position. Moreover, most laser transmitters emit invisible lasers. During the laser emission process, it is impossible to identify with the naked eye whether the actual emission position of the laser is aligned with the target position or the degree of deviation. At the same time, the laser transmitters in the prior art do not have a position adjustment function. After confirming that the laser emission deviates from the target position, the laser can only be re-emitted and roughly adjusted based on experience, and the accuracy of laser emission is poor.

[0005] Therefore, how to clearly and intuitively display the actual emission position of the laser, and conveniently adjust the laser emission position to improve the accuracy of the laser emission position is a technical problem faced by technical personnel in this field. Utility Model Content

[0008] Preferably, the lens portion includes a lens seat and a window lens, the lens seat is provided with a window for positioning the window lens, and the outer side and the inner side of the window are both designed to be waterproof with an inclination.

[0009] Preferably, the laser module includes a grating ring, a second module fixing ring, a focusing lens, a positioning rubber ring, a focusing lens seat, a first module fixing ring, an LD seat, a module positioning sleeve, a laser diode, a spring and a first control circuit board. The top of the LD seat is threadedly connected to the focusing lens seat, and a focusing lens with a grating ring is arranged in the focusing lens seat.

[0010] Preferably, the LD seat is arranged in the module positioning sleeve, and a first control circuit board with a spring sheet and a laser diode is installed at the bottom of the LD seat. The front end of the module positioning sleeve is positioned in the module sleeve by a second module fixing ring, a first module fixing ring and a positioning rubber ring, and the end of the module positioning sleeve is fitted with the fine-tuning rod.

[0011] Preferably, a reference scale line is designed on the outer wall surface of the module sleeve at a position corresponding to the fine-tuning portion.

[0012] Preferably, the outer wall surface of the fine-tuning sleeve is designed with a circle of scales.

[0013] Preferably, the battery part includes a battery sleeve, a battery fixing ring and a battery, and the battery is fixed in the inner cavity of the battery sleeve through the battery fixing ring. A second control circuit board is configured at the connection between the battery part and the module sleeve, which is positioned and assembled through a PCB fixing ring and a PCB fixing sleeve, and is connected to a negative spring to allow the battery to be electrically connected to the laser module in the module sleeve.

[0014] Preferably, the switch portion includes a switch button and a rear cover, and the rear cover is designed to be trapezoidal in shape so that the switch button can be embedded therein by being fixed in place by screws.

[0015] Preferably, the rear sleeve is formed with a cavity, and the inner wall surface of the cavity is formed with an internal thread.

[0016] Preferably, there are two groups of the fine-adjusting parts, which are installed on the module sleeve perpendicularly to each other in a plane and are arranged in contact with the module positioning sleeve inside the module sleeve.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] 1. The laser module of the utility model includes three parts used for positioning and assembly to achieve simple and stable positioning and assembly, namely the first module fixing ring, the positioning rubber ring and the second module fixing ring. Compared with the traditional glue fixing, this setting is not only accurate and stable in positioning, but also can be disassembled and replaced when maintenance and assembly are required, avoiding the problems of strong fixation, residue or corrosion caused by the use of glue.

[0019] 2. The utility model is a laser transmitter designed with a fine-tuning part, and there are two groups of fine-tuning parts, corresponding to the X-axis and the Y-axis respectively. The user can apply pressure or reset the laser module by rotating the fine-tuning rod counterclockwise or clockwise, so as to control the emission angle of the laser module within a certain range. The fine-tuning box module is also designed with scales and scale reference lines.

[0020] 3. The rear sleeve in the present invention is formed with a cavity, and the inner wall surface of the cavity is formed with internal threads. Compared with the design in which the rear sleeve is generally formed with external threads, this design can reduce the overall length of the present invention to a certain extent, so as to facilitate carrying, because the rear sleeve is formed with a cavity, and the inner wall surface thereof is formed with internal threads, which can wrap a part of the battery sleeve. If the battery sleeve is formed with internal threads and the rear sleeve is formed with external threads, then the battery sleeve must reserve a certain length to allow the rear sleeve to be screwed into the battery sleeve so as to be accommodated by the battery sleeve.

[0021] 4. The outer side and the inner side of the window of the lens holder of the utility model are designed to have an inclination, specifically the outer side is designed to be an inverted cone, and the assembly angle of the inner cavity where the window lens is installed is designed to be an inclination non-horizontal design. The purpose of this design is that compared with the horizontally designed exit hole position and the horizontally installed window lens, the pressure they are subjected to is different. The horizontal setting will be more prone to breakage or even bursting problems. By designing the bevel and the inverted cone, the pressure on the lens can be significantly reduced, and the bevel design can divert the liquid when there is liquid to avoid gathering at the window and affecting the use.

[0022] 5. The waterproof grade of the utility model reaches IPX8. The reason is that the connection of each part adopts a tight threaded connection, and each threaded connection is equipped with a sealing ring. In addition, the rear cover and the switch button are integral, and are equipped with screws for reinforcement assembly, and the structure is tighter. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] 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.

[0028] like Figures 1 to 4 As shown, the utility model is a fine-tunable laser transmitter with a scale. The utility model can be roughly divided into several parts, namely a lens part, a laser module, a module sleeve (1), a fine-tuning part, a battery part and a switch part, wherein both ends of the module sleeve (1) are formed with external threads to flexibly connect the lens part and the battery part by threaded connection; the laser module is arranged in the inner cavity of the module sleeve (1), and its position is reinforced and assembled by connecting and fixing the module sleeve (1) with the lens part, and one end of the battery part with an external thread is flexibly connected to the switch part. It should be noted that the positions for connection based on the thread are all provided with sealing rings to assist in assembly, which can effectively improve the sealing performance of the utility model.

[0029] The lens portion comprises a lens seat (2) and a window lens (19), the lens seat (2) is provided with a window for positioning the window lens (19), and the outer side and the inner side of the window are both designed to have an inclination;

[0030] The laser module comprises a grating ring (26), a second module fixing ring (23), a focusing lens (10), a positioning rubber ring (13), a focusing lens seat (14), a first module fixing ring (3), an LD seat (12), a module positioning sleeve (11), a laser diode (9), a spring (21) and a first control circuit board (5);

[0031] The fine-tuning part comprises a fine-tuning sleeve (27), a fine-tuning fixing seat (33), a first O-ring (6), a countersunk screw (22), a positioning pin (30), a fine-tuning rod (29), a module positioning ring (4), a positioning spring (31) and a spring fixing screw (32);

[0032] The battery unit comprises a battery sleeve (25), a battery fixing ring (15) and a battery (18);

[0033] The switch portion comprises a switch button (8) and a rear cover (20).

[0034] Based on the above, the structure of the fine-tuning part can be further described. The fine-tuning rod (29) is positioned in the fine-tuning sleeve (27) by a countersunk screw (22). A hole is provided in the fine-tuning rod (29) to assemble the positioning spring (31). The positioning spring (31) is equipped with a positioning pin (30) and a spring fixing screw (32) to achieve positioning. The fine-tuning part is also equipped with a first O-ring (6) as a sealing ring to be assembled on the fine-tuning fixing seat (33). The fine-tuning fixing seat (33) is installed in the through hole opened on the module sleeve (1) by a threaded connection to position and assemble the fine-tuning part as a whole. Regarding the technical points of the fine-tuning part, it should be noted that there are two groups of fine-tuning parts, which correspond to the X-axis and the Y-axis in the plane respectively. The user can apply pressure or reset the laser module by rotating the fine-tuning rod (29) counterclockwise or clockwise. It can be explained here that the end of the fine-tuning rod (29) is arranged to fit with the end of the laser module in the module sleeve (1), and a module positioning ring (4) is configured at the fitting position to assist assembly. The setting of the module positioning ring (4) can not only assist in positioning and assembly, but also prevent the laser module from deviating when the rotating fine-tuning rod (29) applies pressure to the laser module, thereby improving practicality and stability to a certain extent. Based on the setting of the two groups of fine-tuning parts, the user can control the emission angle of the laser module within a certain range, which meets the use requirements in most occasions. The fine-tuning box module sleeve is also designed with scales and scale reference lines. Such a design can facilitate users to quickly memorize and adjust and reset in specific environments or occasions, avoiding multiple adjustments when the angle needs to be reset before subsequent use.

[0035] In addition, the outer side and the inner side of the window of the lens seat are designed to have an inclination, specifically the outer side is designed to be an inverted cone, and the assembly angle of the inner cavity where the window lens (19) is installed is designed to be an inclination non-horizontal design. The purpose of such design is that compared with the horizontally designed exit hole position and the horizontally installed window lens (19), the pressure they are subjected to is different. The horizontal setting method is more likely to cause the problem of fragmentation or even explosion. By designing the inclined surface and the inverted cone, the pressure on the lens can be significantly reduced, and the inclined surface design can guide the liquid when there is liquid to avoid gathering at the window and affecting the use.

[0036] In addition, the laser module is provided with a grating ring (26), a focusing lens (10) and a corresponding first control circuit board (5) to ensure the quality and effect of laser emission. In addition, in order to protect the fragile LD seat (12), the LD seat (12) is provided with a module positioning sleeve (11). The module positioning sleeve (11) also wraps the focusing lens seat (14) to protect the fragility in the event of falling. The technical point of the laser module that can be emphasized is that the laser module includes three parts for positioning and assembly to achieve simple and stable positioning and assembly of itself, namely, a first module fixing ring (3), a positioning rubber ring (13) and a second module fixing ring (23). The first module fixing ring (3) and the second module fixing ring (23) are respectively arranged at the bottom and the top of the positioning rubber ring (13), wherein the second module fixing ring (23) plays a role in reinforcing the position of the window lens (19). It should be additionally explained that the positioning rubber ring (13) is made of rubber and has a certain elasticity, so that when the fine-tuning part pressurizes or resets the end of the laser module, the front end of the laser module can achieve a certain deflection. If a metal with a certain hardness is used as a positioning part, the laser module itself will be deformed when rotating and pressurizing, which will cause damage or scrapping.

[0037] The battery part comprises a battery sleeve (25), a battery fixing ring (15) and a battery (18). The battery (18) is fixed in the inner cavity of the battery sleeve (25) through the battery fixing ring (15). A second control circuit board (28) is arranged at the connection between the battery part and the module sleeve (1). The second control circuit board (28) is positioned and assembled through a PCB fixing ring (16) and a PCB fixing sleeve (17), and is connected to a negative spring (24) so ​​that the battery (18) can be electrically connected to the laser module in the module sleeve (1). The switch part for controlling the operation of the laser module is connected to the other end of the battery part. The switch part comprises a switch button (8) and a rear sleeve (20). The rear sleeve (20) is designed to be trapezoidal in shape so that the switch button (8) can be fixed in position by screws and embedded therein. The switch part and the battery part are provided with a second O-ring (7) to assist in installation. It is worth mentioning that the rear cover and the switch button are integrated and equipped with screws for reinforced assembly. The structure is tighter and friendly to assembly and disassembly. It can also improve the waterproofness of this part of the switch button. Traditional glue fixation has problems such as strong fixation, residue or corrosion.

[0038] The utility model has a reasonable structure and a waterproof grade reaching IPX8, and can fine-tune the emission angle of the internal laser module to meet the special use requirements in more use occasions.
