Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of endoscopes, in particular to a device for replacing a lens. Background Art
[0002] An endoscope consists of a pipeline, handle, and main unit. Different working conditions often require different pipeline systems, requiring replacement of different pipelines. Due to the high cost of pipelines, some users only need to replace the lens assembly at the front end of the pipeline system to achieve the desired performance. However, replacing the front end lens assembly is inconvenient due to its small size, and can easily contaminate the lens with hands.
[0003] Therefore, the existing technology has defects and needs to be improved. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a device for replacing a lens, which will not contaminate the lens and can better assemble the lens with ease and labor saving.
[0005] The technical solution of the utility model is as follows: a device for replacing a lens is provided, comprising: a sleeve clamp, and a lens limit block connected to the inner side of the sleeve clamp; the sleeve clamp comprises: a sleeve body provided with a movable groove, and an elastic clamping plate connected to the sleeve body; the elastic clamping plate is arranged in the movable groove.
[0006] When the endoscope lens needs to be replaced, directly insert the endoscope lens into the sleeve clamp until the lens contacts the lens limit block, then press the elastic clamping plate with your fingers to clamp the lens, rotate the sleeve clamp or pipeline to separate the lens from the pipeline, and after separation, take out the lens, install another lens into the sleeve clamp to the lens limit block, then insert the pipeline into the sleeve clamp, press the elastic clamping plate with your fingers to clamp the lens, and simultaneously rotate the sleeve clamp or pipeline to thread the lens and pipeline, thereby connecting the lens and pipeline, and then pull the pipeline and lens out of the sleeve clamp to replace the lens. This technical solution can effectively prevent fingers from touching the lens, will not contaminate the lens, and can also better assemble the lens, easily and labor-saving.
[0007] Furthermore, the device for replacing a lens further comprises: a damping ring installed inside the elastic clamping plate, wherein the damping ring can enhance the friction force of the elastic clamping plate clamping the lens, thereby facilitating the clamping of the lens.
[0008] Furthermore, a first anti-slip pattern is provided on the outer surface of the elastic clamping plate.
[0009] Furthermore, the outer surface of the sleeve body is provided with a second anti-slip pattern, and the first anti-slip pattern and the second anti-slip pattern form a circle. The first anti-slip pattern and the second anti-slip pattern are used to prevent fingers from slipping.
[0010] Furthermore, there are two movable grooves and two elastic clamping plates, and the two elastic clamping plates are respectively arranged in one movable groove; the two elastic clamping plates are opposite to each other.
[0011] Furthermore, the lens limiting block is connected to the sleeve body.
[0012] By adopting the above scheme, the utility model provides a device for replacing the lens, which clamps the lens by arranging an elastic clamping piece, thereby allowing the lens to be disassembled and installed; when replacing the lens of an endoscope, the lens assembly can be assembled quickly, conveniently and labor-savingly. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 This is a schematic structural diagram of an embodiment of the present utility model;
[0014] Figure 2 for Figure 1 A schematic diagram of the structure of the embodiment when applied. DETAILED DESCRIPTION
[0015] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0016] See also Figure 1 and Figure 2 The utility model provides a device for replacing a lens, comprising: a sleeve clamp, a lens limit block 10 connected to the inner side of the sleeve clamp; the sleeve clamp comprises: a sleeve body 12 provided with a movable groove, and an elastic clamping plate 13 connected to the sleeve body 12; the elastic clamping plate 13 is arranged in the movable groove.
[0017] When the endoscope lens 14 needs to be replaced, directly insert the endoscope lens 14 into the sleeve clamp until the lens 14 contacts the lens limit block 10, then press the elastic clamping plate 13 with your fingers to clamp the lens 14, rotate the sleeve clamp or pipeline 15 to separate the lens 14 from the pipeline 15, and after separation, take out the lens 14, install another lens 14 into the sleeve clamp to the lens limit block 10, then insert the pipeline 15 into the sleeve clamp, press the elastic clamping plate 13 with your fingers to clamp the lens 14, and at the same time rotate the sleeve clamp or pipeline 15 to thread the lens 14 and the pipeline 15, so that the lens 14 and the pipeline 15 are connected, and then the pipeline 15 together with the lens 14 is pulled out of the sleeve clamp to replace the lens 14.
