Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and 2, in an embodiment of the present invention, a dust cover for a liquid chromatograph includes a base 1, a flexible cover 10 is disposed above the base 1, the liquid chromatograph should be located in the middle of the upper surface of the base 1, and when the flexible cover 10 is in an open state, the flexible cover can wrap the liquid chromatograph and further prevent dust for the liquid chromatograph;

the flexible cover 10 can be dustproof cloth, can also be an aluminum foil telescopic tube, can also be foldable and made of wood materials, namely, the cover body capable of being upwards contracted is the protection range of the device;

as shown in fig. 2, in order to conveniently open the flexible cover 10, the pull ropes 5 are fixedly connected to two sides of the bottom of the flexible cover 10, the upper ends of the pull ropes 5 extend upwards, a device for winding and unwinding the pull ropes 5 is arranged above the flexible cover 10, when the pull ropes 5 are wound, the pull ropes 5 can pull the lower end of the flexible cover 10 upwards, and then the lower end of the flexible cover 10 can move upwards, so that the whole liquid chromatograph can be exposed, and the liquid chromatograph can be conveniently used;

as shown in fig. 2, in order to wind and unwind the pulling rope 5, in this embodiment, it is preferable that the two sides of the upper surface of the base 1 are fixedly connected with the brackets 2, a cavity plate 6 is installed between the upper ends of the two brackets 2, the device for winding and unwinding the pulling rope 5 is installed on the cavity plate 6, and then the cavity plate 6 is used as an installation framework of the winding and unwinding device, the device for winding and unwinding the pulling rope 5 includes a winding shaft 4 rotatably installed inside the cavity plate 6 and a motor 3 installed on one side of the upper end of the bracket 2 to drive the winding shaft 4 to rotate, the motor 3 can drive the winding shaft 4 to rotate forward and backward, so as to wind or unwind the pulling rope 5, and to realize downward closing or upward opening of the flexible cover 10;

as shown in fig. 1, in order to better position the flexible cover 10, the suspension rods 7 are fixedly connected between the two ends of the upper surface of the flexible cover 10 and the cavity plate 6, i.e. the suspension rods 7 can position the upper end of the flexible cover 10;

combine fig. 1 and fig. 2, in order to guarantee when the rolling axle 4 unreels stay cord 5, the lower extreme of flexible cover 10 has sufficient gravity to whereabouts, lower extreme edge rigid coupling at flexible cover 10 has balancing weight 8, because balancing weight 8's quality is great, so it is after losing 5 ascending pulling forces of stay cord, can stimulate the lower extreme downstream of flexible cover 10 because of gravity, be convenient for close of flexible cover 10, and after it closes, in order to avoid the inside dust that gets into in gap between balancing weight 8 and the base 1, there is sealed pad 9 at the lower surface mounting of balancing weight 8, so that it is sealed.

The utility model discloses a theory of operation and use flow: when the device is used, as shown in fig. 1, the liquid chromatograph is positioned in the middle of the upper surface of the base 1, the flexible cover 10 is in a closed state and can prevent dust for the liquid chromatograph, and when the liquid chromatograph needs to be used, the winding shaft 4 rotates to wind the pull rope 5 by driving the motor 3, the pull rope 5 can pull the lower end of the flexible cover 10 upwards, so that the lower end of the flexible cover 10 can move upwards, the whole liquid chromatograph can be exposed, and the liquid chromatograph can be conveniently used;

when flexible cover 10 is closed to needs, motor 3 drives 4 antiport of rolling axle to unreel stay cord 5, lower extreme edge rigid coupling at flexible cover 10 has balancing weight 8, because balancing weight 8's quality is great, so it is losing 5 ascending pulling forces of stay cord after, can be owing to gravity and the lower extreme downstream of pulling flexible cover 10, be convenient for close of flexible cover 10, and after it closes, sealed pad 9 can seal, avoid the dust to get into.
