[0002] Laboratory utensils are usually placed on a utensils rack for subsequent use. The existing utensils rack usually includes a horizontal plate and a vertical plate fixed on the horizontal plate for placing the utensils. A single surface of the vertical plate is inclined at an upward angle with a plurality of drip columns, and the utensils are mounted on the drip columns.

[0003] During laboratory construction, the vessel rack is usually fixed to the wall at a suitable height by drilling holes, or adhesive is applied to the back of the vessel rack for bonding and fixing. However, since the vessel rack has a certain weight, it is difficult to keep it level during the construction process by manually supporting and fixing it, and it is time-consuming and laborious. Some construction workers will build a temporary fixing frame on the wall, but the built fixing frame cannot accurately adjust the fixed height of the vessel rack, and it may tilt slightly due to the vibration of the drilling during the construction process, which is difficult to detect in time, resulting in the installed vessel rack failing to meet the expected standards. Therefore, it is necessary to design a vessel rack fixing mechanism for laboratory construction that can be horizontally calibrated and accurately adjusted to a fixed height. Utility Model Content

DETAILED DESCRIPTION

[0019] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] like Figure 1-4 As shown, a vessel rack fixing mechanism for laboratory construction includes a base 1, a telescopic support rod 2 and a clamping seat 3, the upper end of the telescopic support rod 2 is hinged to the clamping seat 3, and the lower end is fixedly connected to the base 1, the telescopic support rod 2 is provided with a first threaded rod 4, a threaded barrel 6 and a second threaded rod 5 from top to bottom, the threaded barrel 6 is connected to the first threaded rod 4 and the second threaded rod 5 by threads, and the rotation directions of the upper and lower connecting threads of the threaded barrel 6 are opposite, a groove 8 is opened on the clamping seat 3 and a horizontal ruler 7 is arranged at the bottom of the clamping seat 3, symmetrical threaded through holes 10 are arranged on both sides of the groove 8, a third threaded rod 9 is penetrated in the threaded through hole 10, the third threaded rod 9 is threadedly connected to the threaded through hole 10, one end of the third threaded rod 9 is connected to a first rotating cap 12, and the other end is connected to a circular clamping plate 11 for clamping the vessel rack.

[0021] Working principle: the telescopic support rods 2 are preferably provided with two and have a certain cross-section sufficient to support the clamping seat 3. The lower end of the telescopic support rod 2 can be fixedly connected to the base 1 by welding or screw-nut cooperation. The circular clamping plate 11 is preferably arranged at the rear position of the groove so that the circular clamping plate 11 can be clamped after the utensil rack is against the wall. The threaded barrel 6 is connected to the first threaded rod 4 and the second threaded rod 5 by threads, and the rotation directions of the upper and lower connecting threads of the threaded barrel 6 are opposite. The threaded connection method makes the height adjustment of the telescopic support rod 2 more accurate. The rotation directions of the upper and lower rod threads are opposite, which can speed up the adjustment speed. Adjust the clamping seat 3 to be horizontal: judge whether the clamping seat 3 is in a horizontal state by observing the position of the bubble in the level ruler 7. If it is not in a horizontal state, adjust the height of the telescopic support rod 2 by observing the level ruler 7 and rotating the threaded barrel 6 until the clamping seat 3 is in a horizontal state; Clamp the utensil rack: place the utensil without the utensil on it The rack is placed in the groove 8 and is located in the middle of the circular clamping plates 11 on both sides of the groove 8. The third threaded rod 9 in the threaded through hole 10 is rotated by the first rotating cap 12, so that the circular clamping plates 11 on both sides clamp the utensil rack without any utensil placed in the middle position of the groove 8. In order to make the utensil rack against the wall, the utensil rack is generally fixed at the middle and rear position of the groove 8; adjust the height of the utensil rack after clamping and install the utensil rack: adjust the height of the telescopic support rod 2 by rotating the threaded cylinder 6 for the same number of turns, thereby adjusting the height of the utensil rack on the clamping seat 3, observe the level ruler 7, and fine-tune the telescopic support rod 2 by rotating the threaded cylinder 6 to make the utensil rack level. After the utensil rack remains level and is at a suitable installation height, the utensil rack can be installed and fixed. After use, rotate the third threaded rod 9, loosen the circular clamping plate 11, and take away the fixing mechanism. When using it again, move the fixing mechanism to a suitable position and reinstall it.

[0022] Preferably, a non-slip rubber sleeve is provided on the rotating cap 12, so as to facilitate the rotation of the third threaded rod 9 through the first rotating cap 12 to control the circular clamp 11 to clamp or release the circular clamp, thereby improving the comfort of use.

[0023] Preferably, a dustproof component is provided on the side of the clamping seat 3 and at the front end of the groove 8. The dustproof component includes a rotating drum 13, a dustproof film 14 and a counterweight rod 15. A rotating shaft is welded inside the rotating drum 13. One of the two ends of the rotating shaft is connected to a second rotating cap 18. The second rotating cap 18 is penetrated by a latch 16 for fixing the rotating drum 13. One end of the dustproof film 14 is wound around the rotating drum 13, and the other end is wound around the counterweight rod 15. Since the laboratory is under construction, after the vessel rack is fixed, the latch 16 can be opened to pull out The dust-proof film 14 is wound on the rotating drum 13, and the counterweight rod 15 is placed on the top of the vessel rack stand so that the dust-proof film 14 covers the vessel rack. The rotating drum 13 is then fixed by inserting the latch 16. This can protect the vessel rack from dust pollution during laboratory construction. When the dust-proof film 14 needs to be retracted, the latch 16 is opened, the second rotating cap 18 is rotated, and the dust-proof film 14 is rewound onto the rotating drum 13. The dust-proof film 14 is preferably detachably connected to the rotating drum 13 and the counterweight rod 15 by Velcro, magnetism, etc., for easy cleaning and recycling.

[0024] Preferably, rollers are provided at the bottom of the base 1, and limiting members are provided on the rollers. Preferably, four rollers are provided, the front wheels are a pair of universal wheels, and the rear wheels are a pair of driving wheels. Rollers are provided at the bottom of the base 1, which facilitates moving the fixing mechanism to the bottom of the vessel rack for fixing as needed, which can improve the convenience of using the fixing mechanism during laboratory construction.

[0025] Preferably, the dustproof component also includes a placement box 17 for placing the dustproof component. The placement box 17 is arranged on the side of the clamping seat 3 and located at the front end of the groove 8. The counterweight rod 15 can be arranged as a top cover of the placement box 17, which saves costs and facilitates the pulling and use of the dustproof film 14.

[0026] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model.
