Description

Technical Field

[0001] This utility model relates to the field of pipette technology, specifically a glass pipette support. Background Technology

[0002] A pipette is a volumetric instrument used to accurately transfer a specific volume of solution. Hospitals often use pipette stands to store glass pipettes; common materials for these stands include acrylic glass and wood. They are typically placed horizontally or vertically.

[0003] However, in existing vertically placed pipette supports, the pipette fixing slots are all cut into a horizontal plate, which is fixedly installed on the support. This means that if pipettes of different lengths cannot be placed properly, the pipette support needs to be replaced, which is very inconvenient. Therefore, we propose a glass pipette support to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a glass pipette holder to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A glass pipette holder includes a first cylinder and a second cylinder, which are fixedly mounted on the top of a base plate. A threaded rod is vertically arranged inside the second cylinder. One end of the threaded rod is rotatably connected to the bottom of the inner side of the second cylinder through a bearing seat. The other end of the threaded rod passes through the top of the second cylinder and is fixedly connected to a handle. The threaded rod vertically passes through one end of a crossbar, and the other end of the crossbar is vertically passed through by a guide rod. The two ends of the crossbar are respectively provided with threaded through holes for threaded connection with the threaded rod and through holes for the guide rod to pass through. One end of the guide rod is fixedly mounted on the top of the inner side of the first cylinder, and the other end of the guide rod is fixedly mounted on the bottom of the inner side of the first cylinder.

[0007] As a further embodiment of this utility model: a horizontal plate is provided below the crossbar at a position between the first cylinder and the second cylinder. One side of the horizontal plate is fixedly connected to the outside of the first cylinder, and the other side of the horizontal plate is fixedly connected to the outside of the second cylinder. Multiple limiting mechanisms are equidistantly arranged on the horizontal plate. Each limiting mechanism includes a groove, a spring, a limiting block, a slider, and a sliding groove. The groove is equidistantly opened inside the horizontal plate. Both sides of the groove are fixedly connected to one end of two springs, and the other end of the spring is fixedly connected to one side of the limiting block. The other side of the limiting block is in contact with the outside of the pipette. The pipette vertically penetrates the horizontal plate. The horizontal plate has a through hole for the pipette to pass through. A slider is fixedly installed at the bottom of the limiting block. The slider is slidably connected in the sliding groove, which is opened in the bottom of the horizontal plate of the groove.

[0008] As a further embodiment of this utility model: a water-holding box is provided below the horizontal plate between the first cylinder and the second cylinder, and the water-holding box is placed on the top of the base plate between the first cylinder and the second cylinder.

[0009] As a further embodiment of this utility model: a connecting rod is provided on one side of the first cylinder, and a rotating shaft is provided in the middle of the connecting rod. The rotating shaft passes through the connecting rod and the first cylinder laterally. A locking block is fixedly installed at one end of the rotating shaft inside the first cylinder, and a locking block is fixedly installed at the other end of the rotating shaft on one side of the connecting rod. A positioning bolt is provided below the rotating shaft on the connecting rod. The positioning bolt passes through the connecting rod laterally and is screwed into a threaded hole opened on one side of the first cylinder. The connecting rod has a threaded hole for threaded connection with the positioning bolt. A third cylinder is fixed above one side of the connecting rod. An air inlet is opened on one side of the third cylinder. An installation frame is provided inside the third cylinder at the position on the side of the air inlet. The installation frame is fixedly installed inside the third cylinder. Two rods are cross-installed inside the installation frame. A fan is fixedly installed on the rods. Multiple air outlets are equidistantly opened at the bottom of the third cylinder. The air outlets are located directly above the pipette. The pipette passes vertically through a horizontal plate. Multiple through holes are equidistantly opened on the horizontal plate.

[0010] As a further improvement of this utility model: one side of the limiting block is designed to be inclined, and a switch is fixedly installed on the front surface of the second cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model fixes the pipette by rotating the handle, which drives the threaded rod to rotate, and further drives the crossbar to move up and down, making it convenient for medical staff to store the pipette.

[0013] 2. This utility model achieves pipette clamping and fixing on the bracket by passing the pipette through the hole opened on the crossbar and inserting the bottom of the pipette into the through hole opened on the cross plate, thereby squeezing the limiting blocks on both sides and preventing other pipettes from shaking and colliding on the bracket when the pipette is picked up.

[0014] 3. In this utility model, water droplets inside the pipette are introduced into the water container. The connecting rod is turned forward, and the positioning bolt is inserted through the connecting rod and screwed into the bolt hole opened on the side wall of the first cylinder. This makes the air outlet at the bottom of the tube directly above the pipette. The fan is then turned on, and the fan dries the pipette through the air outlet. This facilitates the removal of water from inside the pipette after cleaning and prevents water droplets from sticking to the wall and causing bacteria to grow inside the pipette.

[0023] The working principle of this utility model is as follows:

[0024] When using the glass pipette holder, medical staff tighten the positioning bolt 8, turning the connecting rod 7 backward. This rotates the handle 22, causing the threaded rod 5 to rotate, which in turn moves the crossbar 4 up and down, thus securing the pipette 13 for easy storage. The pipette 13 is then passed through the hole in the crossbar 4, with its bottom extending into the groove 16. This presses against the side limit blocks 18, clamping and fixing the pipette 13 to the holder, preventing other pipettes from slipping when the pipette 13 is removed. 13 shakes and bumps on the support, and the water inside the pipette 13 drips into the water container 23 through the drain hole. The medical staff turns the connecting rod 7 forward, inserts the positioning bolt 8 through the connecting rod 7 and screws it into the bolt hole opened on the side wall of the first cylinder 2, so that the air outlet 12 below the tube body 10 is directly above the pipette 13. The fan 21 is then turned on, and the fan 21 dries the pipette 13 through the air outlet 12, which facilitates the removal of water inside the pipette 13 after cleaning and prevents water droplets from sticking to the wall and causing bacteria to grow inside the pipette 13.
