DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] See also Figure 1 - Figure 3 The utility model provides a technical solution: a liquid chromatograph storage device with good protection, including a liquid chromatograph body 100, a protective support mechanism 200 is arranged on the top of the liquid chromatograph body 100, and the protective support mechanism 200 can not only play a surrounding and protective role on the liquid storage bottle, but also reduce the damage caused by foreign objects. At the same time, the supporting position of the support plate 201 can be adjusted according to the height of the liquid storage bottle to avoid the liquid storage bottle from tipping over, increase the stability and safety of the liquid storage bottle, and increase the storage adaptation range of the liquid storage bottle on the liquid chromatograph body 100. The protective support mechanism 200 includes a lower fixed plate 208 installed on the top of the liquid chromatograph body 100, a support plate 201 is horizontally arranged above the lower fixed plate 208, a telescopic protective tube 202 is arranged between the support plate 201 and the lower fixed plate 208, an adjusting member 204 for adjusting the height of the support plate 201 is arranged on the upper surface of the liquid chromatograph body 100, and a cover plate 203 for sealing and protecting the bottle mouth of the liquid storage bottle is arranged above the support plate 201;

[0022] The adjusting member 204 includes a vertical rail 2041 vertically fixed on the upper surface of the lower fixed plate 208. The vertical rail 2041 is T-shaped when viewed from above. Connecting plates 2042 are fixed on the upper surfaces of the support plate 201 and the cover plate 203. The outer end of the connecting plate 2042 is slidably sleeved on a guide sleeve 2043 on the vertical rail 2041. The two are fixedly connected, which can facilitate the height of the support plate 201 to change as the guide sleeve 2043 moves, making it convenient for the support plate 201 to adapt to liquid storage bottles of different heights.

[0023] In this embodiment, preferably, a limit bolt 2044 is screwed on the outer surface of the guide sleeve 2043, and the inner end of the limit bolt 2044 contacts the surface of the vertical rail 2041, and the position of the guide sleeve 2043 can be limited and fixed by using the friction resistance of the contact.

[0024] In this embodiment, preferably, storage holes 205 for receiving the liquid storage bottles are evenly opened on the surface of the support plate 201, so that the liquid storage bottles can be placed in the storage holes 205 conveniently, thereby providing a stable support for the liquid storage bottles.

[0025] In this embodiment, preferably, a sealing gasket 206 corresponding to the position of the storage hole 205 is provided on the lower surface of the cover plate 203, and the sealing gasket 206 is a rubber gasket, which facilitates the cover plate 203 to drive the sealing gasket 206 to block the bottle mouth of the liquid storage bottle.

[0026] In summary, according to the height of the liquid storage bottle, the support plate 201 can be moved upward, driving the connecting plate 2042 and the guide sleeve 2043 to move upward along the vertical rail 2041. When the height of the support plate 201 is appropriate, the limit bolt 2044 is rotated to make its inner end contact with the surface of the vertical rail 2041, and the height position of the guide sleeve 2043 and the support plate 201 is fixed. At this time, the liquid storage bottle on the liquid chromatograph body 100 is placed into the storage hole 205 from above, and the support plate 20 1 provides a firm support for the waist position of the liquid storage bottle. As the support plate 201 moves, the telescopic protection tube 202 can be telescoped along with the support plate 201, while protecting the periphery of the liquid storage bottle, thereby increasing the protective effect of the liquid storage bottle. The cover plate 203 is then covered on the liquid storage bottle from above the vertical rail 2041, and the sealing gasket 206 seals and protects the bottle mouth of the liquid storage bottle. The guide sleeve 2043 connected to the cover plate 203 is sleeved on the vertical rail 2041, and the positions of the guide sleeve 2043 and the cover plate 203 are fixed.

[0027] Example 2

[0028] Reference Figure 4 , which is the second embodiment of the utility model.

[0029] In this embodiment, preferably, a movable clamping plate 207 for clamping the side of the liquid chromatograph body 100 is movably provided on the side of the lower fixed plate 208, so as to realize a detachable connection between the protective support mechanism 200 and the liquid chromatograph body 100, and anti-slip components 300 are symmetrically provided on the lower surfaces of the two symmetrically distributed movable clamping plates 207.

[0030] In this embodiment, preferably, the anti-slip component 300 includes a vertical plate 301 fixed on the lower surface of the movable clamping plate 207. By providing the anti-slip component 300, the connection strength between the protective support mechanism 200 and the liquid chromatograph body 100 can be increased, which is convenient for stable storage and protection of the liquid storage bottle. The outer side of the vertical plate 301 is provided with an anti-slip plate 302 whose lower end extends to the lower surface of the liquid chromatograph body 100. The length between the vertical plate 301 and the anti-slip plate 302 can be adjusted according to the liquid chromatograph. The height of the instrument body 100 is adjusted, and the anti-slip plate 302 is L-shaped, so that the liquid chromatograph body 100 will not move downward and separate from the protective support mechanism 200. A guide groove 305 is provided on the surface of the vertical plate 301 along its height direction. A sleeve plate 303 slidingly mounted on the vertical plate 301 is fixed to the upper end of the anti-slip plate 302. A clamping rod 304 penetrating the sleeve plate 303 is screwed on the upper end of the anti-slip plate 302. The clamping rod 304 can limit and fix the positions of the anti-slip plate 302 and the sleeve plate 303.

[0031] In summary, when the lower fixed plate 208 is fixed on the top of the liquid chromatograph body 100, the vertical plate 301 fits the surface of the liquid chromatograph body 100, and the anti-slip plate 302 moves along the vertical plate 301 until the lengths of the two are appropriate, and the clamping rod 304 is rotated to limit and fix the positions of the sleeve plate 303 and the anti-slip plate 302, so that the entire anti-slip component 300 is moved with the movable clamping plate 207 and stuck at the bottom of the liquid chromatograph body 100, so that the liquid chromatograph body 100 and the lower fixed plate 208 will not be detached from each other.

[0033] This embodiment is obtained by combining embodiment 1 and embodiment 2.

[0034] When in use, when the entire protective support mechanism 200 is installed on the top of the liquid chromatograph body 100, the anti-slip component 300 is used to increase the installation strength of the two, and then the adjustment component 204 is used to change the height of the support plate 201 and the cover plate 203, so as to stably support the liquid storage bottle used in the liquid chromatograph body 100, avoid the liquid storage bottle from tipping over, and increase the storage safety of the liquid storage bottle.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
