Description

Technical Field

[0001] The utility model belongs to the field of auxiliary tools for optical measurement equipment, and particularly relates to an eyepiece cleaning device for a level. Background Technique

[0002] A level is an optical measurement instrument used to measure the relative height difference between different points, mainly composed of components such as a telescope, a horizontal circle, a vertical circle, and a spirit level tube. When in use, the operator can control the azimuth and pitch angle of the instrument through the horizontal circle and the vertical circle, observe the target point through the telescope, and then record the spirit level tube readings of each target point, so as to calculate the height difference between each point according to the readings.

[0003] Since the operator needs to observe the image of the target point through the eyepiece of the telescope, the clarity of the eyepiece will directly affect the actual observation effect of the operator. In the prior art, if there is dust or sweat stain on the eyepiece of the level, the operator can only wipe the eyepiece manually with a lens cloth or lens paper. Although such a wiping method can remove the stains on the eyepiece to a certain extent, the operation convenience is poor, and the edge area of the lens cannot be cleaned. Over time, it is easy to cause stain accumulation at the edge of the lens, thereby reducing the observable range of the eyepiece and further affecting the use effect of the level.

[0028] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0029] An eyepiece cleaning device for a level, its structure can be composed of Figures 1 - 5A schematic illustration is provided. As shown in the figure, in this embodiment, the eyepiece cleaning device for a level includes: a connecting seat 1, a splicing seat 2, an operating handle, and a cleaning component. The connecting seat 1 is used to achieve the assembly between this device and the eyepiece of the level to be cleaned. The splicing seat 2 is used to install the operating handle and the cleaning component on the connecting seat 1. The operating handle is used to cause relative movement between the cleaning component and the eyepiece lens, so as to wipe and clean the stains attached to the eyepiece lens by means of the cleaning component.

[0030] Specifically, one end of the connecting seat 1 is provided with an eyepiece groove 11 for accommodating the eyepiece of the level. The other end of the connecting seat 1 is provided with a splicing groove 12, and a through hole 13 communicating with the eyepiece groove 11 is arranged inside the splicing groove 12. When in use, the staff can insert the eyepiece of the level into the eyepiece groove 11. At this time, the through hole 13 will be aligned with the lens of the eyepiece, so as to facilitate the cleaning of the lens of the eyepiece by this device. To facilitate the contact between the operating handle and the cleaning component and the lens of the eyepiece, in this embodiment, an installation hole 21 is provided on the splicing seat 2. The operating handle includes a limiting section 31, a connecting section 32, and an operating section 33 connected in sequence. The cleaning component includes a pressing disc 4 and a sponge sleeve 5, and the sponge sleeve 5 is sleeved outside the pressing disc 4. During assembly, the staff can first movably arrange the limiting section 31 inside the installation hole 21, and place the operating section 33 outside the connecting seat 1 to complete the assembly between the splicing seat 2 and the operating handle. Subsequently, the pressing disc 4 is detachably arranged on the end face of the limiting section 31 away from the connecting section 32 to complete the assembly between the cleaning component and the operating handle. Next, the splicing seat 2 is detachably inserted into the splicing groove 12 and the installation hole 21 is aligned with the through hole 13. At this time, the operating handle inside the installation hole 21 will be facing the mirror surface of the eyepiece. The staff can first press the operating handle towards the lens to make the sponge sleeve 5 outside the pressing disc 4 contact the lens of the eyepiece, and then drive the operating handle to rotate, so that relative movement occurs between the cleaning component and the lens through the rotation of the operating handle, completing the wiping and cleaning work of the lens.

[0031] Since the lens in the eyepiece of the level is installed inside the lens barrel, it is easy to form cleaning dead corners in the area of the lens edge, resulting in stubborn stains on the lens edge and affecting the actual use effect of the lens. To solve this problem, in this embodiment, a plurality of pressing protrusions 41 are further provided at the edge of the end face of the pressing disc 4 away from the limiting section 31, and the plurality of pressing protrusions 41 are arranged in a ring on the circumference of the axis of the pressing disc 4. When the cleaning component contacts the lens of the eyepiece, the pressing protrusions 41 can cause the sponge sleeve 5 to deform, improving the fitting effect between the sponge sleeve 5 and the edge part of the lens, so as to facilitate the wiping and cleaning of the edge area of the lens, avoid the formation of cleaning dead corners at the lens edge, and improve the wiping and cleaning effect of the lens.

[0032] To achieve the detachable connection between the extrusion disc 4 and the limiting section 31 and prevent relative rotation between the extrusion disc 4 and the operating handle, as Figure 4 and Figure 5 shown, in this embodiment, a connection head 6 may be provided on the end face of the extrusion disc 4 close to the limiting section 31, and a plurality of limiting strips 61 are provided on the side wall of the connection head 6. Correspondingly, a connection groove 311 should be provided on the limiting section 31, and a plurality of limiting grooves 312 are provided on the inner side wall of the connection groove 311. When assembling the extrusion disc 4 and the limiting section 31, the staff can insert the connection head 6 into the connection groove 311, and make the plurality of limiting strips 61 be inserted into the plurality of limiting grooves 312 one by one to complete the assembly between the extrusion disc 4 and the limiting section 31. When driving the cleaning assembly to move by rotating the operating handle, the cooperation of the limiting strip 61 and the limiting groove 312 can circumferentially limit the extrusion disc 4, so that the rotation of the operating handle can be reliably converted into the relative movement between the cleaning assembly and the lens, ensuring that the device obtains a good lens wiping and cleaning effect.

[0033] In addition, to prevent the extrusion disc 4 from separating from the operating handle during use, the cleaning assembly may further include a connecting rod 7. Specifically, to accommodate the connecting rod 7, an assembly hole 331 communicating with the connection groove 311 may be provided on the end face of the operating section 33 away from the connecting section 32. The connecting rod 7 is placed inside the assembly hole 331. The first end of the connecting rod 7 is connected to the connection head 6, and the second end of the connecting rod 7 is provided with a threaded joint. When assembling the cleaning assembly and the operating handle, the staff can insert the connecting rod 7 into the assembly hole 331 along the connection groove 311. When the connection head 6 enters the connection groove 311, the threaded joint will extend out of the assembly hole 331. At this time, the staff can install a locking nut 71 on the threaded joint, so as to axially limit the cleaning assembly by means of the locking nut 71 and prevent the cleaning assembly from detaching from the operating handle. Correspondingly, when the cleaning assembly needs to be replaced, the staff should first remove the locking nut 71, and then pull the extrusion disc 4 in the direction away from the limiting section 31 so that the connecting rod 7 leaves the operating handle, thereby completing the disassembly of the old cleaning assembly and facilitating the installation of the new cleaning assembly into the device.

[0034] Optionally, to improve the connection reliability between the splicing base 2 and the splicing groove 12, an anti - detachment strip 121 may be provided on the inner side wall of the splicing groove 12, and an anti - detachment groove 22 for accommodating the limiting strip 61 is provided on the side wall of the splicing base 2. When assembling the splicing base 2 and the splicing groove 12, the anti - detachment strip 121 will be inserted into the anti - detachment groove 22, thereby preventing the splicing base 2 from separating from the splicing groove 12 during use.

[0035] Since the device needs to drive the operating handle to rotate during use, in order to prevent the splicing base 2 from rotating synchronously with the operating handle, a first limiting section 23 can be provided on the side wall of the splicing base 2, and a second limiting section 122 that cooperates with the first limiting section 23 is provided inside the splicing groove 12. After the splicing base 2 is inserted into the splicing groove 12, the first limiting section 23 will contact the second limiting section 122, and the cooperation between the first limiting section 23 and the second limiting section 122 can restrict the rotation of the splicing base 2 to prevent the splicing base 2 from rotating inside the splicing groove 12.

[0036] As Figure 2 , Figure 3 and Figure 4 shown, in order to prevent the operating handle from separating from the splicing base 2 during use, a limiting ring 24 can be provided at one end of the mounting hole 21 away from the eyepiece groove 11 in this embodiment, and the inner diameter of the limiting ring 24 is smaller than the inner diameter of the mounting hole 21. Correspondingly, the outer diameter of the limiting section 31 should be equal to the inner diameter of the mounting hole 21, and the outer diameter of the connecting section 32 should be equal to the inner diameter of the limiting ring 24, so as to prevent the operating handle from coming off by means of the limiting ring 24.

[0037] In addition, in order to prevent the cleaning assembly from being damaged during the transportation of the device, a first magnetic attraction ring 81 can be provided on the end face of the limiting ring 24 close to the limiting section 31, and a second magnetic attraction ring 82 that cooperates with the first magnetic attraction ring 81 can be provided on the end face of the limiting section 31 close to the limiting ring 24. During transportation, the first magnetic attraction ring 81 can be attracted to the second magnetic attraction ring 82 so that the cleaning assembly stays inside the mounting hole 21, thereby protecting the cleaning assembly by means of the splicing base 2 and preventing the cleaning assembly from being damaged or contaminated with dust during transportation.

[0038] As an alternative embodiment of this embodiment, in order to improve the assembly reliability between the connecting seat 1 and the level eyepiece, an anti-slip lining 111 made of rubber or silica gel material can also be provided inside the eyepiece groove 11. By providing the anti-slip lining 111, the frictional resistance between the inner wall of the eyepiece groove 11 and the outer wall of the eyepiece can be increased, thereby preventing the connecting seat 1 from separating from the eyepiece during use.

[0039] The effects of the above solutions are described below:

[0040] This embodiment provides an eyepiece cleaning device for a level. The device can be installed on the eyepiece of the level through a connecting seat, and the cleaning component can clean and wipe the lens of the eyepiece by rotating the operating handle, thereby improving the convenience of cleaning the eyepiece of the level. Secondly, the cleaning component in this device can be disassembled, so it is convenient to replace the cleaning component. In addition, this device is provided with a plurality of extrusion protrusions at the edge of the end face of the extrusion disc away from the limiting section. When the cleaning component contacts the lens of the eyepiece, the extrusion protrusions can cause the sponge sleeve to deform, so as to facilitate wiping the edge of the lens and avoid forming a cleaning dead angle at the edge of the lens.

[0041] The foregoing is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
