Description

Technical Field

[0001] The utility model belongs to the field of laboratory instruments and relates to a pipette. Background Art

[0002] A pipette, also commonly known as a pipette gun, is a precision instrument commonly used in laboratories, designed to accurately transfer small or micro amounts of liquid. It is an indispensable tool for biological, chemical and other scientific research fields that require precise liquid measurement.

[0003] After the existing pipette is used, it is usually necessary to store or place it on a special storage rack. For example, a Chinese utility model patent with application number 202220846135.X is called a pipette storage rack, which is specially used for hanging or storing pipettes. However, if the pipette is placed directly on the desktop, it may not only introduce contamination risks, but also cause the desktop to be contaminated with reagents, causing contamination or even corrosion, which will affect the experiment.

[0004] Therefore, the current pipette has certain defects. It does not have the function of standing on the desktop by itself, and must rely on a special storage rack to meet the storage needs, so there is room for improvement. Utility Model Content

[0005] The purpose of the utility model is to propose a pipette in view of the above problems existing in the prior art.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a pipette, comprising: a gun body and a handle, the handle is connected to the gun body, the handle has a first supporting part, the gun body is slidably connected to a sliding member, the sliding member has a second supporting part, the sliding stroke position of the sliding member includes a hidden position and an extended position; when the sliding member is in the extended position, the sliding member extends from the rear end of the gun body, and the first supporting part and the second supporting part form a self-standing support frame.

[0007] Preferably, when the sliding member is in the hidden position, the sliding member is located on the gun body.

[0008] Preferably, one of the sliding member and the gun body is provided with a sliding rail and the other is provided with a sliding block, and the sliding block is connected to the sliding rail so that the sliding member is slidably connected to the gun body.

[0009] Preferably, two travel limit grooves are provided in the slide rail, and when the sliding member is located in the hidden position, the slider is embedded in one travel limit groove to limit the sliding of the sliding member, and when the sliding member is located in the unfolded position, the slider is embedded in the other travel limit groove to limit the sliding of the sliding member.

[0010] Preferably, the sliding member is configured as a sliding cover structure with a U-shaped cross-section, and the sliding member includes two side plate portions, and the two side plate portions are respectively tightly attached to the two sides of the gun body, and the two sides of the gun body are each provided with one of the sliding rails and the sliding block, and the two side plate portions are each provided with the other of the sliding rails and the sliding block, and the two side plate portions are respectively slidably connected to the two sides of the gun body.

[0011] Preferably, the sliding member has an elastic force for clamping the two sides of the gun body through the two side plate parts, and when the sliding member is located in the hidden position or the deployed position, the sliding block is embedded in the travel limit groove under the action of the elastic force.

[0012] Preferably, the second supporting portion includes two supporting surfaces, and the two supporting surfaces are respectively located at the ends of the two side plate portions.

[0013] Preferably, the hidden position and the deployed position are respectively located at two ends of a sliding stroke of the sliding member.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. A sliding part is designed on the pipette, which is usually in a hidden position and does not affect normal use. When the pipette needs to be placed, the sliding part can be pulled out, and the second supporting part on the sliding part cooperates with the first supporting part on the handle to form a self-standing support frame so that the pipette can stand stably on the desktop. Therefore, the pipette does not need to rely on a special storage rack for use, which is very convenient.

[0016] 2. The sliding part and the gun body are slidably connected through a slider and a slide rail structure. The slider is precisely matched with the slide rail, so that the sliding part can slide smoothly along the gun body between the hidden position and the deployed position.

[0017] 3. When the slider is in the hidden position, the slider is embedded in the first travel limit slot. This design effectively limits the further sliding of the slider, so that it remains firmly on the gun body and does not hinder the operation. When the user needs to use the self-supporting function, the slider slides to the unfolded position and then moves into the second travel limit slot. At this time, it not only limits the retraction of the slider, but also ensures the stable construction of the self-supporting frame, so that the pipette can stand steadily on the desktop or laboratory table.

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] like Figure 1-5 As shown, a pipette includes: a gun body 100 and a handle 300, the handle 300 is connected to the gun body 100, the handle 300 has a first support portion 310, the gun body 100 is slidably connected to a sliding member 200, the sliding member 200 has a second support portion 220, and the sliding stroke position of the sliding member 200 includes a hidden position and an extended position; when the sliding member 200 is in the extended position, the sliding member 200 extends from the rear end of the gun body 100, and the first support portion 310 and the second support portion 220 form a self-standing support frame.

[0026] It should be noted that the gun body 100 and the handle 300 constitute the main structure of the pipette, the front end of the gun body 100 has a pipette tip interface for installing the pipette tip, the end of the handle 300 has a first support portion 310, and the sliding member 200 is installed at the rear of the gun body 100 and can slide backward. In addition, in the example, the hidden position and the unfolded position are respectively located at the two ends of the sliding stroke of the sliding member 200.

[0027] This pipette is designed to solve the problem that traditional pipettes need to rely on a dedicated storage rack for storage. A sliding member 200 is added to the gun body 100, and the sliding member 200 has two position states: a hidden position and an expanded position. In daily use, the sliding member 200 is in a hidden position and is completely integrated into the gun body 100, which does not affect the normal operation and carrying of the pipette. When the experimenter needs to temporarily place the pipette, he only needs to slide the sliding member 200 to the expanded position. At this time, the sliding member 200 extends from the rear end of the gun body 100, and the second support portion 220 thereon works together with the first support portion 310 on the handle 300 to form a stable self-supporting support frame, so that the pipette can stand firmly on the laboratory table or other flat surfaces without worrying about the tip contacting the desktop.

[0028] When the pipette is actually used, the operator can hold the handle 300 to operate it, and when it needs to be placed, the sliding member 200 is pulled out backwards, and the pipette is laid backwards. At this time, the first support portion 310 on the handle 300 is in contact with the desktop, and the second support portion 220 on the sliding member 200 is also in contact with the desktop, so that the pipette can stand on the desktop in a posture similar to leaning back through the self-supporting support frame. Through the above design, the pipette can stand firmly on the laboratory bench or desktop without any external support, avoiding the risk of contamination, and also saving the trouble of finding or using a special storage rack, greatly improving the convenience and flexibility of use.

[0029] On the basis of the above embodiment, when the sliding member 200 is in the hidden position, the sliding member 200 is located on the gun body 100. When the sliding member 200 of the pipette is in the hidden position, it is cleverly integrated on the gun body 100 and is consistent with the gun body 100. This design ensures that the sliding member 200 does not interfere with the user's experience during the pipetting operation, while maintaining the overall smooth lines and simple appearance of the pipette.

[0030] like Figure 1-4 As shown, based on the above embodiment, one of the sliding member 200 and the gun body 100 is provided with a slide rail 110 and the other is provided with a slider 230 , and the slider 230 is connected to the slide rail 110 to make the sliding member 200 and the gun body 100 slidably connected.

[0031] The sliding member 200 and the gun body 100 are slidably connected by the slider 230 and the slide rail 110. The slider 230 precisely matches the slide rail 110, so that the sliding member 200 can smoothly slide between the hidden position and the deployed position along the gun body 100. The combined design of the slide rail 110 and the slider 230 ensures that the movement of the sliding member 200 is both stable and reliable and easy to control.

[0032] Based on the above embodiment, two travel limit grooves 111 are provided in the slide rail 110. When the sliding member 200 is in the hidden position, the slider 230 is embedded in one travel limit groove 111 to limit the sliding of the sliding member 200. When the sliding member 200 is in the unfolded position, the slider 230 is embedded in the other travel limit groove 111 to limit the sliding of the sliding member 200.

[0033] When the sliding member 200 is in the hidden position, the slider 230 is just embedded in the first travel limit groove 111. This design effectively limits the further sliding of the sliding member 200, so that it is firmly held on the gun body 100 and does not hinder the operation. When the user needs to use the self-supporting function, the sliding member 200 slides to the unfolded position, and the slider 230 immediately moves into the second travel limit groove 111. At this time, it not only limits the retraction of the sliding member 200, but also ensures that the self-supporting support frame is firmly constructed, so that the pipette can be stably self-supporting on a desktop or a laboratory table.

[0034] like Figure 1-5 As shown, on the basis of the above embodiment, the sliding member 200 is configured as a sliding cover structure with a U-shaped cross-section, and the sliding member 200 includes two side plate portions 210, and the two side plate portions 210 are respectively close to the two sides of the gun body 100, and the two sides of the gun body 100 are respectively provided with one of the sliding rails 110 and the sliding block 230, and the two side plate portions 210 are respectively provided with the other of the sliding rails 110 and the sliding block 230, and the two side plate portions 210 are respectively slidably connected to the two sides of the gun body 100.

[0035] In the specific structure, the sliding member 200 adopts a sliding cover structure with a U-shaped cross section. This design not only increases the stability of the structure, but also ensures a close fit with the gun body 100. The two side plates 210 of the sliding member 200 are closely attached to the two sides of the pipette gun body 100. This design is not only beautiful, but more importantly, it ensures the smoothness and stability of the sliding member 200 during sliding, avoids shaking or jamming, and improves the smoothness of the overall operation. In addition, the two side plates 210 are respectively connected to the two sides of the gun body 100 through the slide rail 110 and the slider 230 system, ensuring that the sliding member 200 is accurately positioned and stable during the sliding process.

[0036] On the basis of the above embodiment, the sliding member 200 has elastic force to clamp the two sides of the gun body 100 through the two side plates 210 , and when the sliding member 200 is in the hidden position or the unfolded position, the slider 230 is embedded in the travel limit groove 111 under the action of the elastic force.

[0037] The elastic force generated by the two side plates 210 ensures that the slider 230 can automatically fit into the corresponding travel limit slot 111 once the slider 200 reaches the hidden position or the unfolded position during the sliding process, and the position can be locked without additional operation, and the slider 230 can leave the travel limit slot 111 under the push of external force. The subtlety of this embodiment is that it uses simple physical principles to achieve automatic positioning, reduces the tediousness of manual operation, and makes the pipette more flexible and convenient during use.

[0038] like Figure 1-5 As shown, based on the above embodiment, the second support portion 220 includes two support surfaces 221, and the two support surfaces 221 are respectively located at the ends of the two side plate portions 210. Preferably, the two support surfaces 221 and the surface of the first support portion 310 are on the same plane.

[0039] The innovation of the second support part 220 lies in the two support surfaces 221 located at the ends of the side plate part 210 of the sliding member 200. This design is a key component of the self-standing support frame. When the sliding member 200 slides from the hidden position to the unfolded position, the two support surfaces 221 and the first support part 310 on the handle 300 form a stable three-point support structure. It ensures the maximum contact area, provides sufficient stability and load-bearing capacity, and can stand steadily on the desktop even when the pipette is fully loaded, avoiding tipping or shaking.

[0040] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0041] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0042] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
