Technical Field
[0001] The utility model relates to the technical field of laser distance measurement, in particular to an aperture adjustment structure of a circular laser distance meter. Background Art
[0002] A nail gun is a product composed of a gun body and a magazine assembly. It is divided into electric nail guns, pneumatic nail guns, gas nail guns, manual nail guns, etc. The gun body assembly is composed of a gun body, cylinder, balance valve, switch assembly, firing pin assembly, buffer pad, gun nozzle, gun slot, etc. The pressure difference between compressed air and atmospheric pressure is used to make the firing pin reciprocate in the cylinder through the trigger switch; the magazine assembly is composed of a gun head, gun cover, fixed magazine, movable magazine and other accessories. The nail is sent to the gun cover slot through a compression spring or tension spring. When the firing pin comes out of the gun nozzle, the nail is driven out.
[0003] At present, construction both at home and abroad is moving towards standardization. During fastening and drilling operations, the distance between two points needs to be measured with a ruler. For example, to fix a water pipe, it is required to hammer a nail or drill a hole every 30CM. At this time, after the first point is completed, the distance to the second point needs to be measured with a ruler. This method is time-consuming and labor-intensive. It is difficult for one person to complete it and requires the cooperation of a second person. Sometimes the construction wall is uneven and the distance measured with a ruler is prone to errors.
[0004] In view of this, the present invention solves the above technical problems by proposing an aperture adjustment structure of a circular laser distance meter. Utility Model Content
[0005] (1) Technical problems solved
[0006] When tightening or drilling, the distance between two points needs to be measured with a ruler. For example, to fix a water pipe, it is required to drive a nail or punch a hole every 30cm. At this time, after the first point is completed, the distance to the second point needs to be measured with a ruler. This method is time-consuming and labor-intensive. It is difficult for one person to complete it and requires the cooperation of a second person. Sometimes the construction wall is uneven and the distance measured by the ruler is prone to errors.
[0007] In response to the above-mentioned technical deficiencies, the present invention provides a technical solution for the aperture adjustment structure of a circular laser distance meter. During fixed operation, the distance between two fixed points can be adjusted to the size of the laser distance meter for direct irradiation without the need for traditional ruler measurement, thereby solving the problems raised in the above-mentioned background technology.
[0008] (2) Technical solution
[0009] In order to solve the above problems, the present invention provides the following technical solutions:
[0010] The laser beam is driven by a laser to move the laser beam to the target position, and the laser beam is driven by a laser to move the laser beam to the target position.
[0011] As a preferred technical solution of the present invention, a conical lens is fixed inside the annular lens, a focusing lens is fixed at the end of the laser adjustment disk 3, and a laser lamp is fixed at the other end of the laser adjustment disk.
[0012] As an optimal technical solution of the present invention, the laser adjustment disk is provided with a scale, which represents the radius of the circular laser size. When the laser adjustment disk is rotated, the size of the circular light emitted by the laser is used to determine the next striking position.
[0013] As a preferred technical solution of the present invention, the light of the laser lamp is focused by a focusing lens, and then the light hits the conical lens, and then the light is converted into a circular shape by the taper of the conical lens and projected onto the annular lens.
[0014] As a preferred technical solution of the present invention, the surface of the annular lens is provided with a plurality of 45° steps, and one of the two surfaces of the steps is a frosted surface to prevent light leakage, and the other side is a high-transmittance surface to emit annular light.
[0015] As a preferred technical solution of the present invention, a heat sink is clamped on the outer side of the end of the laser adjustment disk for dissipating heat when the laser lamp works for a long time.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. The sliding groove opened on the surface of the sliding sleeve and the three legs on the lens mounting frame move linearly on the sliding sleeve through the sliding groove, which can prevent the lens mounting frame from deviation during movement, so that the light spot is always located at the center of the conical lens and the focusing lens for projection, making the projection effect and spacing test more accurate, and no manual measurement is required when measuring the striking distance.
[0018] 2. When the lens mounting frame moves away from the annular lens, the radius of the laser ring projected by the annular lens becomes larger. Conversely, when the lens mounting frame moves toward the annular lens, the radius of the laser ring projected by the annular lens becomes smaller. The striking distance is adjusted accordingly. The scale setting on the surface of the laser adjustment disk can make the automatic measurement of the striking distance more accurate. When fixed on an irregular working surface, light measurement will be more accurate.
[0019] 3. Turn on the power of the laser distance meter during operation. At this time, a laser ring with the muzzle of the nail gun as the center point will appear. After fixing the first point, when working at the second fixed point, you only need to press the edge of the ring aperture to the previous fixed point. At this time, you can directly tighten the work, eliminating the step of size measurement.
[0020] 4. The heat sink connected to the outer side of the end of the laser adjustment disk can dissipate the heat generated by the laser lamp during long-term operation, preventing excessive heat concentration from damaging the internal circuit of the gun body. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0028] See also Figure 1-5 As shown, an aperture adjustment structure of a circular laser distance meter includes a gun body 1 and a gun nozzle 2 for nail removal. The front end of the gun body 1 is fixedly connected to the gun nozzle 2. A laser 11 is connected to the top side of the gun body 1 by a snap. A laser adjustment disk 3 is provided inside the laser 11 for rotation. The laser adjustment disk 3 is used to adjust the spacing when the gun is shooting and nailing out. A threaded groove 4 is provided on the inner wall of the laser adjustment disk 3. A sliding sleeve 5 is provided inside the laser adjustment disk 3. Three sliding grooves are provided inside the sliding sleeve 5, and each sliding groove passes through the outer wall of the sliding sleeve 5. A lens mounting frame 6 is provided inside the sliding sleeve 5. Three supporting feet are protruded from the surface of the lens mounting frame 6, and the three supporting feet are correspondingly inserted into the sliding grooves on the surface of the sliding sleeve 5. , one of the legs extends to the outside of the sliding sleeve 5 and is located inside the threaded groove 4. The laser adjustment disk 3 is rotated to push one of the legs so that the lens mounting frame 6 moves linearly inside the sliding sleeve 5, and the lengths of the two legs are consistent with the thickness of the sliding groove; a circular lens 10 is provided at the end of the laser adjustment disk 3 and on one side of the laser lamp 9, and a conical lens 7 is fixed inside the circular lens 10. A focusing lens 8 is fixed at the end of the laser adjustment disk 3, and a laser lamp 9 is fixed at the other end of the laser adjustment disk 3; a scale is provided on the laser adjustment disk 3, which represents the radius of the circular laser size. When the laser adjustment disk 3 is rotated, the size of the circular light emitted by the laser is used to determine the next striking position;
[0029] The light of the laser lamp 9 is focused by the focusing mirror 8, and then hits the conical lens 7, and then the light is converted into a circular shape through the taper of the conical lens 7 and projected onto the annular lens 10; the surface of the annular lens 10 is provided with multiple 45° steps, and one side of the two sides of the steps is frosted to prevent light leakage, and the other side is a high-transmittance surface to emit annular light; the outer side of the end of the laser adjustment disk 3 is clamped with a heat sink 12 for dissipating heat when the laser lamp 9 is working for a long time.
[0030] In this embodiment, when the first strike is completed and the next strike is measured, the laser lamp 9 is first turned on so that its circular laser light will hit the position where it needs to be struck. One of the legs of the lens mounting frame 6 is located in the threaded groove 4 and then the laser adjustment disk 3 is rotated. When the laser adjustment disk 3 rotates, the lens mounting frame 6 is driven by one of the legs to move along the slide groove inside the laser adjustment disk 3. The light of the laser lamp 9 is focused by the focusing mirror 8 and then hits the conical lens 7. The conical structure of the conical lens 7 converts the light into a circular shape and projects it onto the annular lens 10. Finally, it is projected to the position where it needs to be struck and passes through the surface of the sliding sleeve 5. The three legs on the sliding groove and the lens mounting frame 6 are located on the sliding sleeve 5 through the sliding groove and move linearly, which can prevent the lens mounting frame 6 from deviation during movement, so that the light spot is always located at the center of the conical lens 7 and the focusing lens 8 for projection. When the laser distance meter is turned on during operation, a laser ring with the muzzle of the nail gun as the center point will appear. After the first point is fixed, when working at the second fixed point, it is only necessary to press the edge of the ring aperture to the previous fixed point. At this time, the tightening operation can be carried out directly, making the projection effect and spacing test more accurate, and no manual measurement is required when measuring the striking distance.
[0031] And through the scale setting on the laser adjustment disk 3, the scales are 300mm, 400mm, 500mm, 600mm, and 800mm, which represent the circular laser sizes of 300mm, 400mm, 500mm, 600mm, and 800mm radius respectively. When a larger spacing is required, the laser adjustment disk 3 can be rotated in the direction of the larger size, and the lens mounting frame 6 will move away from the circular lens 10. The light hitting the conical lens 7 is projected onto the circular lens 10, and then passes through the outermost part of the circular lens 10. The 45° step on the side projects the laser ring to the position where the striking is required to determine the striking interval. By analogy, when the lens mounting frame 6 moves in the direction away from the annular lens 10, the radius of the laser ring projected by the annular lens 10 becomes larger. Conversely, when the lens mounting frame 6 moves in the direction close to the annular lens 10, the radius of the laser ring projected by the annular lens 10 becomes smaller, thereby adjusting the striking interval. Moreover, the scale setting on the surface of the laser adjustment disk 3 can make the automatic measurement of the striking interval more accurate.
[0032] It should be noted that: among the multiple 45° steps provided on the annular lens 10, the radius of the laser ring projected by the outermost step is the maximum, and the radius of the laser ring projected by the gradually inward 45° steps gradually decreases.
