Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser technology, and in particular to a laser. Background Technology
[0002] Single-frequency all-solid-state lasers have advantages such as narrow linewidth, good frequency stability, and low noise, and have wide applications in laser remote sensing, gravitational wave detection, ultracold atom experiments, and coherent communication.
[0003] For example, Chinese patent application CN202122330942.4 discloses a high-stability dual-wavelength laser, which includes a first housing. An internal thread is provided in an opening at one end of the first housing, and a laser emitting tube is threaded onto it. A first foam sleeve and a second foam sleeve are provided, with a mounting groove within the first foam sleeve to fix the laser body in position. The first and second foam sleeves cover the laser body, thus providing cushioning during a fall and improving the internal stability of the device, preventing impact on internal electronic components. However, this design has the following technical problems:
[0004] First, the laser body may be accidentally knocked over when not in use, causing damage to the laser body. Although the above structure can protect the laser body, if the laser body is accidentally dropped, the laser emitting tube may come into contact with the ground, causing damage to the laser emitting tube. It can be seen that the above structure is difficult to effectively protect the laser emitting tube.
[0005] Second, the above structure, through the arrangement of the first foam sleeve, the second foam sleeve, the first housing, the second housing and the rubber sealing sleeve, increases the diameter of the laser body, making the laser body inconvenient to grip. Utility Model Content
[0006] To address the problems mentioned in the background section regarding the ineffective protection of the laser emitter and the increased diameter of the laser body causing inconvenience in gripping, this utility model provides the following technical solution:
[0007] A laser includes a laser body, and a laser emitting tube is disposed on an end face of the laser body.
[0008] The laser body is covered with a protective device for protecting the laser body.
[0009] The protective device includes an inflation box, a gas supply hose, and a protective ring. The inflation box is fixed to the end of the laser body away from the laser emitting tube. There are multiple gas supply hoses, which are set on the outer side wall of the laser body. One end of the gas supply hose is connected to the inflation box, and the other end is connected to the protective ring. The protective ring is sleeved on the outside of the laser emitting tube. The inflation box inflates or deflates the gas supply hose to control whether the gas supply hose expands or not.
[0010] Furthermore, the gas box is annular and is fitted onto the end of the laser body away from the laser emitting tube. Multiple gas supply hoses are attached to the outer wall of the laser body and are spaced apart along the circumference of the laser body.
[0011] Furthermore, a plurality of mounting slots are provided on the outer side wall of the laser body, each mounting slot extending along the length direction of the laser body, and the plurality of mounting slots are spaced apart on the laser body circumferentially, the gas supply hose is disposed in the mounting slot, and when the gas supply hose expands, at least a portion of the gas supply hose protrudes outside the mounting slot.
[0012] Furthermore, the outer diameter of the protective ring is smaller than the diameter of the laser body, and at least a portion of the gas supply hose is attached to the end face of the laser body where the laser emitting tube is located.
[0013] Furthermore, an adsorption magnetic block is fixed on the end face of the laser body at the end where the laser emitting tube is located, and a follower magnetic block is provided on the protective device at a position corresponding to the adsorption magnetic block, and the adsorption magnetic block and the follower magnetic block attract each other.
[0014] Furthermore, the adsorption magnetic block includes a first annular magnetic block and a second annular magnetic block, both of which are arranged with the axis of the laser emitting tube as the center. The follower magnetic block includes a third magnetic block and a fourth magnetic block. The third magnetic block is disposed on the protective ring and corresponds to the position of the first annular magnetic block. The fourth magnetic block is disposed on the gas supply hose located on the end face of the laser body and corresponds to the position of the second annular magnetic block. The first annular magnetic block and the third magnetic block attract each other, and the second annular magnetic block and the fourth magnetic block attract each other.
[0015] Furthermore, the laser body has multiple threaded holes at one end near the inflation box for limiting the inflation box. The inflation box has connecting lugs at positions corresponding to the threaded holes. When the inflation box is fitted onto the laser body, the connecting bolts pass through the connecting lugs and extend into the threaded holes.
[0016] Furthermore, the air box has an annular cavity inside, and one side of the annular cavity has multiple air inlets for connecting with the air delivery hose.
[0017] The protective device includes a limiting cover, which is disposed on the annular cavity. The limiting cover is provided with a piston for cooperating with the inflation box to control the contraction or expansion of the gas delivery hose.
[0018] Furthermore, a plurality of electric push rods for controlling the extension and retraction of the piston within the annular cavity are installed on one side of the limiting cover.
[0019] Compared with the prior art, the beneficial effects of this utility model are:

Detailed Implementation
[0029] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.
[0030] Please see Figures 1-5 This utility model provides a laser, including a laser body 100, with a laser emitting tube 101 disposed on one end face of the laser body 100. A protective device 200 is sleeved on the outside of the laser body 100 to protect the laser body 100 and the laser emitting tube 101. The protection of the laser body 100 and the laser emitting tube 101 by the protective device 200 makes it less likely that the laser body 100 and the laser emitting tube 101 will be damaged if the laser body 100 is accidentally knocked over.
[0031] The protective device 200 includes an inflation box 210, gas supply hoses 212, and protective rings 214. The inflation box 210 is fixed to the end of the laser body 100 away from the laser emitting tube 101. Multiple gas supply hoses 212 are provided on the outer wall of the laser body 100. One end of each gas supply hose 212 is connected to the interior of the inflation box 210, allowing the inflation box 210 to inflate or deflate the hoses. When inflated, the hoses expand, protecting the laser body 100. The other end of each hose 212 is connected to the protective ring 214, which is fitted over the laser emitting tube 101, thus protecting it. Furthermore, the protective ring 214 can be an annular foam sleeve, ensuring that if the laser body 100 is accidentally dropped, the protective ring 214 contacts the ground, effectively protecting the laser emitting tube 101.
[0032] Preferably, the inflation box 210 is annular and fitted onto the end of the laser body 100 away from the laser emitting tube 101. Multiple gas supply hoses 212 are spaced apart circumferentially on the outer wall of the laser body 100. Because the inflation box 210 is fitted onto the laser body 100 and the protective ring 214 is fitted onto the laser emitting tube 101, the gas supply hoses 212 can be securely attached to the outer wall of the laser body 100.
[0033] The laser body 100 has multiple threaded holes 102 at one end near the inflation box 210 for limiting the inflation box 210. A connecting lug 211 is provided on the inflation box 210 at a position corresponding to the threaded hole 102. When the inflation box 210 is fitted over the laser body 100, the connecting bolt passes through the connecting lug 211 and extends into the threaded hole 102, so that the inflation box 210 is fitted over the laser body 100 more securely.
[0034] Furthermore, the outer wall of the laser body 100 is provided with multiple mounting slots 105, each extending along the length of the laser body 100. These mounting slots 105 are spaced apart circumferentially on the laser body 100. A gas supply hose 212 is attached and fixed within the mounting slot 105. When the gas supply hose 212 expands, at least a portion of it protrudes outside the mounting slot 105. This ensures that when the laser body 100 falls, the gas supply hose 212 contacts the ground before the laser body 100, providing cushioning and preventing direct contact between the laser body 100 and the ground, thus protecting the laser body 100.
[0035] Furthermore, in this embodiment, the outer diameter of the protective ring 214 is smaller than the diameter of the laser body 100. That is, as... Figure 1 As shown, in this embodiment, when the gas supply hose 212 is connected to the protective ring 214, at least a portion of the gas supply hose 212 will be attached to the end face of the laser body 100. The expansion of the gas supply hose 212 protects the end face of the laser body 100. Furthermore, since the protective ring 214 is connected to the gas supply hose 212, when the gas supply hose 212 expands, the gas supply hose 212 located on the end face of the laser body 100 will drive the protective ring 214 to move along the axial direction of the laser emitting tube 101 towards the end of the laser emitting tube 101, thereby allowing the protective ring 214 to better protect the laser emitting tube 101.
[0036] Furthermore, an adsorption magnetic block is fixed on the end face of the laser body 100 at one end where the laser emitting tube 101 is located (see...). Figure 2 (See 103 and 104), and a follower magnetic block is provided on the protective device 200 at the position corresponding to the adsorption magnetic block (see Figure 3 (213 and 215). The adsorption magnetic block and the follower magnetic block attract each other so that when the gas in the gas delivery hose 212 is extracted, the auxiliary protection device 200 is reset to prevent it from affecting the normal operation of the laser emitting tube 101.
[0037] More specifically, in this embodiment, the adsorption magnet includes a first annular magnetic block 103 and a second annular magnetic block 104, both of which are concentrically arranged with the axis of the laser emitting tube 101 as their center. Correspondingly, the follower magnetic block includes a third magnetic block 213 and a fourth magnetic block 215. The third magnetic block 213 is disposed on the end face of the protective ring 214 facing the laser body 100, and the fourth magnetic block 215 is disposed on the gas delivery hose 212 located on the end face of the laser body 100. The position of the first annular magnetic block 103 corresponds to the position of the third magnetic block 213, and the position of the second annular magnetic block 104 corresponds to the position of the fourth magnetic block 215. The first annular magnetic block 103 and the third magnetic block 213 attract each other, and the second annular magnetic block 104 and the fourth magnetic block 215 attract each other. When gas is filled into the gas supply hose 212, the gas supply hose 212 on the end face of the laser body 100 will expand by overcoming the flow between the adsorption magnetic block and the follower magnetic block; when the gas in the gas supply hose 212 is extracted, the adsorption magnetic block and the follower magnetic block attract each other, which can help the protective ring 214 and the gas supply hose 212 located on the end face of the laser body 100 to reset.
[0038] Furthermore, the magnetic poles at the ends of the first annular magnetic block 103 and the second annular magnetic block 104 that are away from the laser body 100 can be the same. By controlling the size of the first annular magnetic block 103, the second annular magnetic block 104, the third magnetic block 213 and the fourth magnetic block 215, as well as the distance between them, magnetic interference between the same magnetic poles of the first annular magnetic block 103, the second annular magnetic block 104, the third magnetic block 213 and the fourth magnetic block 215 can be avoided.
[0039] Furthermore, an infrared sensor 216 is installed on one side of the inflation box 210. The infrared sensor 216 is used to detect whether the hand is gripping the laser body 100. When the operator grips the laser body 100, the infrared sensor 216 detects that the surface of the laser body 100 is gripped, the gas inside the gas supply hose 212 is extracted, and the gas supply hose 212 retracts into the mounting groove 105. When the operator's hand moves away from the laser body 100, the infrared sensor 216 detects that the laser body 100 is not gripped, and the gas supply hose 212 begins to inflate.
[0040] The air filling box 210 has an annular cavity 217 inside. A plurality of air inlets 218 are provided on one side of the annular cavity 217 for connecting with the air delivery hoses 212, so that the gas in the annular cavity 217 can be delivered to the plurality of air delivery hoses 212.
[0041] The protective device 200 includes a limiting cover 220, which is fixed to the annular cavity 217 of the inflation box 210 by bolts. The limiting cover 220 includes a piston 222 for cooperating with the inflation box 210 to control the contraction or expansion of the gas supply hose 212. The piston 222 is disposed in the annular cavity 217 and moves along the axis of the laser body 100 within the annular cavity 217. When the piston 222 moves to reduce the volume within the annular cavity 217, it pushes the gas within the annular cavity 217 into multiple gas supply hoses 212, causing the gas supply hoses 212 to expand. The gas supply hoses 212 protect the laser body 100, and the protective ring 214 protects the laser emitting tube 101. When the piston 222 increases the volume within the annular cavity 217, it draws out the gas inside the gas supply hoses 212 to facilitate the operator's use of the laser body 100.
[0042] Multiple electric push rods 221 are also provided between the limiting cover 220 and the piston 222. The electric push rods 221 drive the piston 222 to move. The electric push rods 221 and the infrared sensor 216 are electrically connected to an external controller so that the infrared sensor 216 can detect whether the laser body 100 is being gripped. The multiple electric push rods 221 extend and retract synchronously to control the movement of the piston 222 within the annular cavity 217. Multiple telescopic rods 223 for limiting the piston 222 are installed on one side of the limiting cover 220. The telescopic rod 223 includes a sleeve and a rod body, and the sleeve is fixedly installed between the limiting cover 220 and the piston 222. By limiting the piston 222 through the telescopic rods 223, the movement of the piston 222 within the annular cavity 217 is limited.
[0043] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
