Abstract
Description
Technical Field
[0001] The utility model relates to a pipette, in particular to a retractable handle structure of a pipette, belonging to the technical field of pipettes. Background Art
[0002] A pipette is a quantitative pipetting tool commonly used in biological, chemical, medical and other laboratories. It is usually composed of an adjusting knob, a piston, a pipette tip and a tube body. The volume of liquid to be absorbed or discharged can be accurately set by adjusting the knob. The pipette has the advantages of easy operation, high accuracy and good repeatability.
[0003] During the use of the pipette, since each person's hand size and operating habits are different, the optimal handle length required during use is also different. However, in the existing technology, people are usually unable to adjust the handle length of the pipette, which not only reduces the convenience and comfort of the staff during use, but also reduces the flexibility of the pipette during use. Especially in a complex experimental environment, if the handle is too long, it is easy to collide with other experimental instruments, affecting the smooth progress of the experiment.

[0006] Preferably, a group of slots are formed on the outer surface of the limit plate, and the limit block is matched with the slots. The limit block can be limited by clamping the limit block in the slots.
[0007] Furthermore, the spring is sleeved on the outer surface of the sliding rod, and the spring is fixedly connected to the outer surface of the telescopic handle shell. The spring mainly plays a role in resetting the sliding rod. As the sliding rod is reset, it can drive the limit block to be clamped in the groove opened on the outer surface of the limit plate.
[0008] Preferably, a reserved sliding cavity is opened on the outer surface of the pipette body, and a sliding block is fixedly connected to the inner wall of the telescopic handle shell, and the sliding block is located in the upper half of the inner wall of the telescopic handle shell.
[0009] Specifically, the reserved sliding cavity is slidably connected to the inner wall of the sliding block, and the inner surface of the telescopic handle shell contacts the outer surface of the pipette body. Through the sliding connection between the reserved sliding cavity and the sliding block, the telescopic handle shell can play a limiting and guiding role.
[0010] Preferably, the two limit plates are fixedly connected to the inner wall of the pipette body, the sliding rod passes through the telescopic handle shell and is slidably connected to the inner wall of the telescopic handle shell, and a reserved cavity is opened on the outer surface of the pipette body, and the limit plate is fixedly connected to the inner wall of the pipette body through the reserved cavity.
[0011] The utility model provides a retractable handle structure for a pipette, which has the following beneficial effects:
[0012] 1.

The length of the pipette body can be adjusted by extending and retracting the telescopic handle shell on the outer surface of the pipette body. The sliding rod is pressed by the control handle to drive the mounting plate to move until the limit block is disengaged from the slot provided on the limit plate, thereby releasing the limit on the telescopic handle shell. At this time, people can adjust the length of the pipette body by sliding the telescopic handle shell upward or downward. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The embodiment of the utility model provides a retractable handle structure of a pipette.
[0024] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , including a pipette body 1, people can use the pipette body 1 to complete the pipetting operation during the experiment. The outer surface of the pipette body 1 is provided with a telescopic handle shell 2. The length of the pipette body 1 can be adjusted by moving the telescopic handle shell 2 on the outer surface of the pipette body 1. An adjusting mechanism 3 is provided inside the pipette body 1. The adjusting mechanism 3 includes two limit plates 301 and a sliding rod 302. One end of the sliding rod 302 is fixedly connected with a control handle 303. By setting the control handle 303, people can press the sliding rod 302 more conveniently. The other end of the sliding rod 302 is fixedly connected with a mounting plate 305. As the sliding rod 302 is pressed, the mounting plate 305 can be driven to move. The outer surface of the control handle 303 is fixedly connected with a spring 304. When the sliding rod 302 is pressed, the spring 304 is in a compressed state. The outer surface of the mounting plate 305 is fixedly connected with a group of limit blocks 306.
[0025] Please refer to Figure 4 A group of slots are formed on the outer surface of the limiting plate 301, and the limiting block 306 is matched with the slots. By locking the limiting block 306 into the slots, the limiting block 306 can be limited.
[0026] Please refer to Figure 4 The spring 304 is sleeved on the outer surface of the sliding rod 302, and the spring 304 is fixedly connected to the outer surface of the telescopic handle housing 2. The spring 304 mainly plays a role in resetting the sliding rod 302. As the sliding rod 302 is reset, it can drive the limit block 306 to be clamped in the slot opened on the outer surface of the limit plate 301.
[0027] Please refer to Figure 2 A reserved sliding cavity 4 is opened on the outer surface of the pipette body 1 , and a sliding block 5 is fixedly connected to the inner wall of the telescopic handle housing 2 , and the sliding block 5 is located in the upper half of the inner wall of the telescopic handle housing 2 .
[0028] Please refer to Figure 2The reserved sliding cavity 4 is slidably connected to the inner wall of the sliding block 5, and the inner surface of the telescopic handle housing 2 is in contact with the outer surface of the pipette body 1. Through the sliding connection between the reserved sliding cavity 4 and the sliding block 5, the telescopic handle housing 2 can play a role of limiting and guiding.
[0029] Please refer to Figure 4 The two limit plates 301 are fixedly connected to the inner wall of the pipette body 1, the sliding rod 302 passes through the telescopic handle housing 2 and is slidably connected to the inner wall of the telescopic handle housing 2, and a reserved cavity is opened on the outer surface of the pipette body 1, and the limit plates 301 are fixedly connected to the inner wall of the pipette body 1 through the reserved cavity.
[0030] Working principle: During the use of the device, when it is necessary to adjust the length of the pipette body 1, people can press the sliding rod 302 through the control handle 303, thereby driving the mounting plate 305 to move until the limit block 306 is disengaged from the slot provided on the limit plate 301, so as to release the limit of the telescopic handle housing 2. At this time, people can adjust the length of the pipette body 1 by sliding the telescopic handle housing 2 upward or downward. When the telescopic handle housing 2 is slid to a suitable position, people can release the control handle 303. At this time, the sliding rod 302 can be driven to reset under the elastic force of the spring 304, until the limit block 306 is engaged in the slot provided on the limit plate 301, so as to limit the telescopic handle housing 2, thereby completing the adjustment of the length of the pipette body 1, which not only improves the convenience and comfort of the staff during use, but also improves the flexibility of the device during use, and can effectively reduce the probability of the pipette body 1 colliding with other containers during use, further ensuring that the experiment can proceed smoothly.
