[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0019] The present application provides an HPLC isolator, which is mainly used to solve the problem that the HPLC isolator host is stuck on the guide rail, but the HPLC isolator cannot be installed on different guide rails, which is inconvenient to use, and provides the following technical solutions, which will be described in detail below:

[0020] Embodiment 1:

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, in some embodiments, a fixing box 2 is provided below the isolator body 1, a mounting mechanism 3 for easy disassembly is provided between the isolator body 1 and the fixing box 2, a clamping mechanism 4 clamped on different guide rails is provided inside the fixing box 2; an operating key 5 is fixedly installed on the isolator body 1; the clamping mechanism 4 includes a screw 401 threadedly connected to the inside of the fixing box 2, a slide plate 402 is symmetrically threadedly connected to the middle part of the screw 401, a sliding hole 403 is constructed on the fixing box 2, the slide plate 402 slides in the sliding hole 403, and a clamping plate 404 is fixed at the end of the slide plate 402; the screw 401 is constructed with threads in opposite directions and a knob 405 is fixed at one end; a clamping groove 406 is provided on the clamping plate 404.

[0022] Specifically: by setting a convenient disassembly installation mechanism 3 between the isolator body 1 and the fixed box 2, the installation and disassembly process is made simpler and faster; a clamping mechanism 4 is provided in the fixed box 2, which can be clamped on different guide rails, which means that the isolator body 1 can adapt to guide rails of different specifications and models, providing greater flexibility and applicability, and the clamping mechanism 4 can increase the adaptability and versatility of the isolator body 1.

[0023] The working principle here is: when the isolator body 1 needs to be used, first use the installation mechanism 3 to install the isolator body 1 on the fixed box 2, and an installation mechanism 3 that is easy to disassemble is set between the isolator body 1 and the fixed box 2, so that the installation and disassembly process is simpler and faster; after the isolator body 1 is installed, the clamping mechanism 4 can be used to clamp on different guide rails, specifically: the clamping mechanism 4 is installed in the fixed box 2. One end of the screw 401 is connected to the inside of the fixed box 2 through a thread, and the other end is provided with a knob 405, and the knob 405 is used to control the rotation of the screw 401. When the knob 405 rotates, the screw 401 will also rotate accordingly. Since the threads on the screw 401 are symmetrical and opposite, it will drive the slide plate 402 to move, thereby adjusting the clamping force of the clamping plate 404. There is a clamping plate 404 at the end of the slide plate 402, and a clamping groove 406 is provided on the clamping plate 404. This clamping groove 406 is used to clamp the isolator body 1 on guide rails of different widths, providing greater flexibility and applicability.

[0026] like Figure 1 , Figure 2As shown, in some embodiments, the mounting mechanism 3 includes a mounting rod 301 rotatably connected to the top of the isolator body 1 and a fixed rod 302 fixed to the top of the fixed box 2, and a circular array of mounting buckles 303 and a mounting plate 304 are fixed on the mounting rod 301 and the fixed rod 302, and the mounting buckle 303 is slidably connected to the outside of the mounting plate 304. The working principle here is: rotate the mounting rod 301 so that the mounting buckle 303 on the mounting rod 301 is stuck on the mounting plate 304 of the fixed rod 302, and the mounting buckle 303 on the fixed rod will also be stuck on the mounting plate 304 of the mounting rod 301, and the isolator body 1 can be installed on the fixed box 2 when it is used; when it needs to be disassembled, the mounting rod 301 is rotated at this time so that the mounting buckle 303 is no longer stuck in the mounting plate 304, so that the isolator body 1 can be removed from the fixed box 2, which is convenient for installation and disassembly.
