Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.

The utility model provides a fixing device for reagent bottles of a protein tracer, which can be directly added on or around the existing protein tracer to fix the reagent bottles which are originally and directly placed, so that the reagent bottles are prevented from being turned over under the drive of the vibration of a machine or due to the small amount of the reagent.

Referring to fig. 1, fig. 1 shows a schematic structural diagram of a reagent bottle fixing device of a protein blotting instrument in an embodiment: comprises a base 100, wherein a fixing component 200 for fixing a reagent bottle is arranged on the base 100. A plurality of fixing members 200 may be provided on one base 100 to form a plurality of stoppers for preventing the reagent bottles from being caught, thereby allowing a plurality of reagent bottles to be accommodated at the same time.

It is worth mentioning that the reagent bottle fixing device of the western blotting instrument provided by the utility model can be directly arranged on the existing protein blotting instrument or on a table surface around the western blotting instrument, does not need to replace the original equipment, and is convenient and low in use cost.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a fixing assembly 200 in the present embodiment. The fixing assembly 200 includes a base plate 220, a clamping jaw 240 and a connecting shaft 260 for connecting the base plate 220 to the base 100, the clamping jaw 240 is movably connected with the base plate 220, at least two clamping jaws 240 are provided, and at least two clamping jaws 240 move relatively to clamp the reagent bottle.

Illustratively, the base plate 220 is annular, and the clamping jaws 240 are uniformly arranged along the circumferential direction of the base plate 220 and move along the radial direction of the base plate 220. The clamping and opening action is accomplished by movement of the clamping jaw 240 relative to the base plate 220. The circular base plate 220 is more beneficial to directly placing the cylindrical reagent bottle on the base plate 220, and meanwhile, the clamping jaws 240 are convenient to form a circular holding structure relative to the reagent bottle. Of course, the bottom plate 220 may be a solid disk with a hollow-out portion.

Suitably, the gripping jaws 240 are adapted to grip the gripping end of the reagent bottle extending upwardly along the bottom tray 220 so that the reagent bottle can be placed directly between the gripping jaws 240 from above the bottom tray 220.

Optionally, a guide slot 222 is provided on the bottom plate 220, and a corresponding protrusion 242 is provided on the clamping jaw 240, and the protrusion 242 slides in the guide slot 222, thereby defining the moving path and the moving direction of the clamping jaw 240 relative to the bottom plate 220.

Further, the fixing assembly 200 further includes an elastic member 280, and the clamping jaw 240 moves relative to the bottom plate 220 under the tension of the elastic member 280. Suitably, the space formed between the clamping jaws 240 under the condition that the elastic member 280 is normally extended is slightly smaller than the peripheral width of the reagent bottle, so that the elastic member 280 can be ensured to be in a stretched state when the reagent bottle is clamped by the clamping jaws 240, and the resilience of the elastic member 280 pulls the clamping jaws 240 to gather together towards the center direction of the bottom plate 220 so as to clamp the reagent bottle.

Optionally, the clamping end of the clamping jaw 240 is provided with a guide ramp 246, the top of the guide ramp 246 being inclined away from the center of the base plate 220. That is, when the reagent bottle is prevented from being placed on the bottom plate 220, the clamping jaws 240 can be pressed outward by the structure of the reagent bottle itself against the resilience of the elastic member 280 by the abutment of the guide slope 246 and the bottom wall of the reagent bottle, thereby facilitating the placement of the reagent bottle.

Alternatively, the elastic member 280 has one end connected to the connection shaft 260 and the other end connected to the clamping jaw 240.

Optionally, the reagent bottle fixing device for the western blot apparatus further includes a vibration assembly 300, which is used for driving the clamping jaw 240 to vibrate so that the reagent bottle vibrates under the clamped condition, shaking up the reagent in the bottle, and keeping the reagent in the bottle uniform in the state of standing for a long time.

In the existing protein blotting instrument, a reagent bottle is only placed at a certain position, and a sampling tube only absorbs a sample from a fixed position after extending into the reagent bottle. The precipitate is generated after long-term storage, which results in inaccurate detection result of the sample. The vibration assembly 300 is additionally arranged in the device, so that the shaking can be assisted to be uniform, and the detection result is more stable.

For example, referring to fig. 1 again, the vibration assembly 300 includes a motor box 320 and a vibration motor 340 installed in the motor box 320, wherein an output end of the vibration motor 340 contacts with the connecting shaft 260 and drives the connecting shaft 260 to vibrate.

Optionally, in order to avoid the base 100 being driven by the connecting shaft 260 to also generate vibration, a damping structure 124 is disposed at the connection position of the connecting shaft 260 and the base 100. The damping structure 124 may be a damping layer made of a damping material such as foam or felt, or a damping mechanism made of a damping component such as a spring.

In order to improve the flexibility of the base 100, the base 100 is provided at the bottom thereof with height-adjustable mounting legs 120 so that the mounting height of the base 100 can be adjusted.

Additionally, the bottom of the mounting foot 120 is optionally provided with a cushion 122.

Optionally, the vibration assembly 300 further includes a time controller for adjusting a vibration duration of the vibration motor 340 and a power controller for controlling a vibration amplitude of the vibration motor 340. So that the vibration frequency, the time length and the vibration amplitude of the reagent bottle can be adjusted.
