Technical Field

[0001] The utility model belongs to the field of laboratory instruments and relates to a pipette with a self-supporting function. 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 solve the above problems in the prior art and to provide a pipette with a self-supporting function.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a pipette with a self-supporting function, 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 hinged with a rotating part, the rotating part has a second supporting part, the rotation stroke position of the rotating part includes a hidden position and an unfolded position; when the rotating part is in the unfolded position, the rotating part is flipped open from the rear end of the gun body, and the first supporting part and the second supporting part form a self-supporting support frame.

[0007] Preferably, when the rotating member is located at the hidden position, the rotating member covers the gun body.

[0008] Preferably, one of the rotating member and the gun body is provided with a rotating shaft and the other is provided with an axial hole, and the rotating shaft is connected to the axial hole so that the rotating member is hinged to the gun body.

[0009] Preferably, one of the rotating member and the gun body is provided with a limit block and the other is provided with two travel limit grooves, when the rotating member is located in the hidden position, the limit block is embedded in one of the travel limit grooves to limit the rotation of the rotating member, and when the rotating member is located in the deployed position, the limit block is embedded in the other of the travel limit grooves to limit the rotation of the rotating member.

[0010] Preferably, the rotating member includes a cover body portion and two arm portions, the two arm portions are arranged in parallel and are integrally connected to the cover body portion, the two arm portions are each provided with one of the rotating shaft and the axial hole, the two sides of the gun body are each provided with the rotating shaft and the other of the axial hole, and the two arm portions are hinged to the two sides of the gun body through the rotating shaft and the axial hole.

[0011] Preferably, the two arm portions are each provided with the limit block and one of the two travel limit grooves, and both sides of the gun body are also provided with the limit block and the other of the two travel limit grooves.

[0012] Preferably, the second supporting portion includes two supporting points, and the two supporting points are located on the cover portion.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0022] 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.

[0023] like Figure 1-4 As shown, a pipette with a self-supporting function comprises: a gun body 100 and a handle 300, wherein the handle 300 is connected to the gun body 100, the handle 300 has a first supporting portion 310, the gun body 100 is hinged with a rotating member 200, the rotating member 200 has a second supporting portion 210, and the rotating stroke position of the rotating member 200 includes a hidden position and an unfolded position; when the rotating member 200 is in the unfolded position, the rotating member 200 is flipped open from the rear end of the gun body 100, and the first supporting portion 310 and the second supporting portion 210 form a self-supporting support frame.

[0024] This solution aims to solve the problem that traditional pipettes cannot stand independently and stably on the desktop. Among them, the gun body 100 is the main part of the pipette, and the gun body 100 is connected to the handle 300. The handle 300 not only provides a position for the user to hold the pipette, but also has a first support part 310 at its bottom, which is one of the key components of the self-supporting structure. A rotating member 200 is hinged at the rear end of the gun body 100, and the rotating member 200 can rotate between a hidden position and an unfolded position. When hidden, the rotating member 200 is close to the gun body 100 and does not affect the normal use of the pipette. When the pipette needs to be placed, it is turned over to the unfolded position. At this time, the rotating member 200 will open from the rear end of the gun body 100, thereby driving the second support part 210 to the set position. When the rotating member 200 is unfolded, its second support part 210 and the first support part 310 on the handle 300 together constitute a stable support structure, so that the pipette can stand independently on the desktop without any external support, greatly improving the convenience and flexibility of use.

[0025] When the pipette needs to be placed, the rotating member 200 is flipped back to make it reach the unfolded position, and then the pipette is placed on a desktop or a laboratory table in a backward posture. At this time, the pipette is supported on the desktop by the first support portion 310 and the second support portion 210, so that the pipette can stand independently on the desktop without any external support.

[0026] On the basis of the above-mentioned embodiment, when the rotating member 200 is in the hidden position, the rotating member 200 covers the gun body 100. Since the rotating member 200 is in the hidden position when not in use, the rotating member 200 can fit closely with the gun body 100, and the overall volume will not increase, which is convenient for storage in a compact experimental environment, reduces the occupied space, makes the appearance of the entire pipette more smooth and harmonious, and ensures the simple beauty of the professional instrument.

[0027] like Figure 4 As shown, based on the above embodiment, one of the rotating member 200 and the gun body 100 is provided with a rotating shaft 220 and the other is provided with an axial hole 110 , and the rotating shaft 220 is connected to the axial hole 110 to hinge the rotating member 200 and the gun body 100 .

[0028] In this embodiment, the connection between the rotating shaft 220 and the shaft hole 110 allows the rotating member 200 to rotate smoothly and stably on the gun body 100, ensuring a smooth transition from the hidden position to the deployed position and providing a basis for the self-supporting function.

[0029] On the basis of the above-mentioned embodiment, one of the rotating member 200 and the gun body 100 is provided with a limit block 230 and the other is provided with two travel limit grooves 120. When the rotating member 200 is located in the hidden position, the limit block 230 is embedded in one travel limit groove 120 to limit the rotation of the rotating member 200. When the rotating member 200 is located in the unfolded position, the limit block 230 is embedded in the other travel limit groove 120 to limit the rotation of the rotating member 200.

[0030] The two limit grooves correspond to the hidden position and the unfolded position of the rotating member 200 respectively. When the rotating member 200 is in the hidden position, the limit block 230 is just embedded in the first travel limit groove 120, which effectively limits the further rotation of the rotating member 200, ensuring that it remains in a tightly closed state and will not be accidentally opened due to external force. When the self-supporting function is needed, the rotating member 200 rotates to the unfolded position. At this time, the limit block 230 automatically embeds into the second travel limit groove 120, which not only limits the unfolding angle of the rotating member 200, but also ensures the stability of the support frame, ensuring that the pipette can stand on its own without tipping over. It ensures that in the event of any unexpected movement or slight impact, the rotating member 200 will not automatically change from the hidden position to the unfolded position or retract from the unfolded position, thereby improving the stability and safety of the pipette.

[0031] like Figure 1-4 As shown, on the basis of the above embodiment, the rotating member 200 includes a cover body portion 240 and two arm portions 250, the two arm portions 250 are arranged in parallel and are integrally connected to the cover body portion 240, the two arm portions 250 are each provided with a rotating shaft 220 and one of the shaft holes 110, and the other of the rotating shaft 220 and the shaft hole 110 are each provided on both sides of the gun body 100, and the two arm portions 250 are hinged to both sides of the gun body 100 through the rotating shaft 220 and the shaft hole 110.

[0032] The structural design of the rotating member 200 is very clever. It is composed of a cover body 240 and two parallel arm parts 250, forming an integral and stable structure. The two arm parts 250 are arranged in parallel and form a whole with the cover body 240. The cover body 240 is hinged to both sides of the gun body 100 through the two arm parts 250. When the rotating member 200 rotates, the position of the cover body 240 changes.

[0033] On the basis of the above embodiment, the two arm parts 250 are further provided with a limit block 230 and one of the two travel limit slots 120, and both sides of the gun body 100 are further provided with a limit block 230 and the other of the two travel limit slots 120. This structure can achieve a better locking effect, and the locking force exerted on the rotating member 200 is greater and more uniform when it is in the hidden position and the unfolded position.

[0034] On the basis of the above-mentioned embodiment, the second support portion 210 includes two support points 211, and the two support points 211 are located at the cover body 240. When the rotating member 200 is flipped from the hidden position to the unfolded position, the two support points 211 and the first support portion 310 on the handle 300 together form a stable triangle or similar structure, ensuring that the pipette can stand on the desktop stably without worrying about tipping or sliding. In addition, the position design of the support point 211 takes into account the universal applicability of contact with the desktop, and can provide a good support effect regardless of the material of the desktop, reducing the instability caused by the hardness or unevenness of the desktop.

[0035] 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.

[0036] 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.

[0037] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] 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.
