Description

Technical Field

[0001] The invention relates to the field of experimental instruments, and in particular to a base for fixing a cup body. Background Art

[0002] In chemical and biological experiments, beakers and measuring cylinders are essential experimental equipment. During the experiment, researchers may accidentally touch the beaker or measuring cylinder, causing it to fall over. On the one hand, this will cause liquid to flow out and waste materials. Most importantly, these liquids may cause harm to the human body. Therefore, there is a need to fix the beaker and measuring cylinder on the table during the experiment.

[0003] Existing fixtures for beakers or graduated cylinders, if designed to hold both, typically take up a large desk shelf, significantly congesting lab space. Consequently, these fixtures are typically separate and have limited functionality, serving only one purpose: to hold either the beaker or the graduated cylinder. This is because the beaker has the same diameter at the top and bottom, but the bottom and barrel of the graduated cylinder have different diameters. Furthermore, the taller, slenderer cylinder has a higher center of gravity and is more susceptible to tipping. For example, beakers and graduated cylinders with capacities ranging from 5ml to 1000ml have an outer diameter ranging from 20mm to 105mm and a height ranging from 32mm to 158mm. Meanwhile, the outer diameter of the graduated cylinder at its largest point ranges from 32mm to 100mm, and the height of the graduated cylinder ranges from 115mm to 430mm. If the clamping element can grip the side of the beaker but only the largest diameter at the bottom of the graduated cylinder, the beaker can be held securely, but the graduated cylinder could still tip due to the gap between the barrel and the clamping element.

[0004] Besides their limited functionality, existing cup holders also face the drawback of requiring a highly complex design for their drive and clamping components if they are to be able to hold cups of varying sizes while also being user-friendly and portable. For example, Chinese patent application CN201811618915.3 discloses a portable cup holder with an adjustable function. This design utilizes a complex assembly consisting of a transmission rod, pressure rod, worm, worm gear, and clamping plate to clamp the outer wall of the cup. This complex design not only increases manufacturing costs, but also increases the risk of failure due to the excessive number of transmission components.

[0005] Therefore, a multifunctional base is needed that can fix both the beaker and the graduated cylinder, has a simple driving mode, and is easy to use. Summary of the Invention

[0008] Furthermore, the cross-type variable diameter ring guard includes a plurality of ribs, a connecting shaft and a locking strip, and through holes are provided at both ends and the middle of the ribs. The plurality of ribs are cross-connected to each other in an X-shape to form a ring, and the connecting shaft passes through the overlapping through holes to connect the ribs. A protrusion is provided on the surface of the connecting shaft in the middle of any two adjacent X-shaped cross connections, and the locking strip is clamped on the protrusion.

[0009] Furthermore, a flexible contact portion is provided on a side of the connecting shaft close to the cup body.

[0010] Furthermore, the support rod includes a first horizontal section and a first vertical section, the end of the first horizontal section is connected to the cross-type reducer ring, and the end of the first vertical section is fixed to the slider; or the support rod is tilted relative to the first plate.

[0011] Furthermore, the soft suction cup includes an air vent on the top, a pit is provided at the center of the first plate, a center hole is opened in the middle of the pit, and the suction cup assembly also includes a soft cover pad, a hard cover plate, a spring, a connecting part and a pull ring; the soft cover pad covers the air vent, the hard cover plate is located above the soft cover pad, one end of the spring is against the hard cover plate, and the other end of the spring is against the inner side of the first plate; the connecting part passes through the spring and the center hole, one end is connected to the hard cover plate, and the other end is connected to the pull ring, and the pull ring is located in the pit and stuck above the center hole.

[0012] Furthermore, the soft cover pad is fixedly connected to the hard cover piece.

[0013] Furthermore, the edge of the soft cover pad is discontinuously connected to the edge of the hard cover sheet.

[0014] Furthermore, the suction cup assembly also includes a soft cover pad fixing seat, and a locking portion is provided on the side of the second plate close to the first plate. The soft cover pad fixing seat includes a ring foot and a fixing ring, the ring foot is locked in the locking portion, and the soft cover pad is located inside the fixing ring.

[0015] Furthermore, the soft cover pad includes an outer flat portion and an inner concave portion, the outer flat portion is clamped on the soft cover pad fixing seat, and the inner concave portion is pressed on the air outlet.

[0016] Furthermore, the height of the pull ring is smaller than the height of the pit.

[0017] Furthermore, the connecting portion includes a pull rod or a pull rope.

[0018] Furthermore, the second plate is provided with a recessed area on a side away from the first plate, and when the soft suction cup squeezes the air for adsorption, the soft suction cup is located in the recessed area.

[0019] The embodiments of the present invention have at least the following technical effects: An embodiment of the present invention provides a base for fixing a cup body, wherein a clamping assembly is arranged on the support shell, and a cross-type variable diameter ring guard can change its diameter under the external force of a human hand, driving the support rod and the slider to move on the slide rail, and can clamp beakers or measuring cylinders of different diameters; the slide rail is arranged in a groove, so that the bottom of the cup body to be clamped can contact more with the upper surface of the first plate, and the placement is more stable.

At this time, when the beaker or measuring cylinder is moved, the cross-type reducing ring guard has been locked and cannot expand outward, and the three support rods are fixed by the cross-type reducing ring guard and will not move due to external force. The three support rods and the cross-type reducing ring guard provide strong support for the beaker or measuring cylinder; at the same time, because the diameters of the bottom and the cylinder body of the measuring cylinder are different, when the inner side of the cross-type reducing ring guard contacts the cup body, the support rods do not contact the cup body, leaving enough space for the bottom of the measuring cylinder to be placed, but the cross-type reducing ring guard can lock the cylinder body, so that the measuring cylinder can be firmly fixed on the base.

[0020] In the present invention, a soft suction cup is used to adsorb the base on the desktop, and the cross-type variable diameter ring guard drives the support rod and the slider to move on the slide rail. When the inner side of the cross-type variable diameter ring guard contacts the cup body, the support rod does not contact the cup body, thereby solving the technical problems of a single fixed base function and complex driving, and achieving the technical effect that one base can fix both the beaker and the measuring cylinder, and has a simple driving method and is easy to use.

DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

It should also be understood that terms such as those defined in common dictionaries should be understood to have meanings consistent with their meanings in the context of the prior art and, unless specifically defined as such, will not be interpreted in an idealized or overly formal sense.

[0026] It will be understood by those skilled in the art that, unless otherwise stated, the singular forms "a," "an," "said," and "the" used herein may also include plural forms. It should be further understood that the term "comprising" used in the specification of the present invention refers to the presence of the stated features, integers, steps, operations, elements, and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or combinations thereof. The term "and / or" used herein includes all or any one of the associated listed items and all combinations thereof.

[0027] For the first aspect, see Figures 1 to 6 , an embodiment of the present invention provides a base for fixing a cup body, comprising: a supporting shell, the supporting shell comprising a first plate 11, a second plate 12 and a side panel 13; a clamping assembly, the clamping assembly comprising a slide rail 21, a slider 22, a support rod 23, and a cross-type reducing ring guard 24, the first plate 11 comprising at least three grooves 111, the three grooves 111 are radially and evenly distributed on the first plate 11, the slide rail 21 is arranged in the groove 111, the slider 22 is connected to the slide rail 21, one end of the support rod 23 is fixed to the slider 22, and the other end of the support rod 23 is connected to the cross-type reducing ring guard 24, when the diameter of the cross-type reducing ring guard 24 changes under the action of external force, it drives the support rod 23 and the slider 22 to move on the slide rail 21; a suction cup assembly, the suction cup assembly comprising a soft suction cup 31, the soft suction cup is fixed on the side of the second plate 12 away from the first plate 11; when the inner side of the cross-type reducing ring guard 24 contacts the cup body, the support rod 23 does not contact the cup body.

[0028] In this embodiment, the clamping assembly is mounted on the support housing. The cross-type reducer ring 24 can change diameter under the action of manual force, driving the support rods 23 and sliders 22 to move on the slide rails 21, capable of clamping beakers or measuring cylinders of different diameters. The slide rails 21 are positioned within the grooves 111, allowing the bottom of the cup to be clamped to more closely contact the upper surface of the first plate 11, providing more stable placement. During use, the entire base is first attached to the table using a soft suction cup 31. The soft suction cup 31 does not damage the table and facilitates easy installation in various locations. The cross-type reducer ring 24 is then expanded outward, simultaneously driving the three support rods 23 outward. The beaker or measuring cylinder is then placed on the first plate 11. The cross-type reducer ring 24 is then manually retracted inward until the inner side of the cross-type reducer ring 24 contacts the outer wall of the beaker or measuring cylinder, locking the cross-type reducer ring 24 from expanding outward. The three support rods 23 are then arranged on the first plate 11 in a tripod-like manner. At this time, when the beaker or measuring cylinder is moved, the cross-type reducing ring guard 24 has been locked and cannot expand outward, and the three support rods 23 are fixed by the cross-type reducing ring guard 24 and will not move due to external force. The three support rods 23 and the cross-type reducing ring guard 24 provide strong support for the beaker or measuring cylinder; at the same time, because the diameters of the bottom and the cylinder body of the measuring cylinder are different, when the inner side of the cross-type reducing ring guard 24 contacts the cup body, the support rods 23 do not contact the cup body, leaving enough space for the bottom of the measuring cylinder to be placed, but the cross-type reducing ring guard 24 can lock the cylinder body, so that the measuring cylinder can be firmly fixed on the base.

[0029] In this embodiment, a soft suction cup 31 is used to adsorb the base on the table, and the cross-type reducing ring guard 24 drives the support rod 23 and the slider 22 to move on the slide rail 21. When the inner side of the cross-type reducing ring guard 24 contacts the cup body, the support rod 23 does not contact the cup body, thereby achieving a technical effect that one base can fix both the beaker and the measuring cylinder, and the driving method is simple and easy to use.

[0030] Optionally, the cross-type variable diameter ring guard 24 includes a plurality of ribs 241, a connecting shaft 242 and a locking bar 243. Through holes are set at both ends and the middle of the ribs 241. The plurality of ribs 241 are connected to each other in an X-shaped cross to form a circle. The connecting shaft 242 passes through the overlapping through holes to connect the ribs. A protrusion 2421 is set on the surface of the connecting shaft 242 in the middle of any two adjacent X-shaped cross connections, and the locking bar 243 is stuck on the protrusion 2421.

[0031] In this embodiment, the design of the ribs 241 allows the cross-type variable diameter ring guard 24 to flexibly change its diameter when subjected to external force, adapting to cup bodies of different sizes. Through the X-shaped cross connection and the fixation of the connecting shaft 242, the stability of the structure during the deformation process is ensured, and structural failure caused by deformation is avoided. It is easy to lock and unlock, and the combination of the protrusion 2421 and the locking bar 243 provides a simple and effective locking mechanism. A protrusion 2421 is set on the surface of the connecting shaft 242 in the middle of any two adjacent X-shaped cross connections. When the cross-type variable diameter ring guard 24 is adjusted to a suitable diameter and contacts the cup body, the locking bar 243 can be easily stuck on the protrusion 2421 to achieve locking and prevent the ring guard from accidentally expanding. Here, the role of the locking bar 243 is to ensure that the ring guard does not expand. The unlocking process is also simple. You only need to move the locking bar 243 to disengage it from the protrusion 2421. This design also facilitates maintenance and replacement. If a portion of the cross reducer retainer 24 (such as a rib or locking bar) becomes damaged or worn, that portion can be replaced independently without having to replace the entire clamping assembly. This reduces maintenance costs and simplifies the maintenance process.

[0032] Furthermore, one end of the lock bar 243 can be fixedly connected to a protrusion 2421 to prevent the lock bar 243 from being lost. Figure 3 The locking strip 243 shown is only an example, and it is easy to think of more strip-shaped objects with buttonholes that can play the role of the locking strip 243. The number and length of the ribs 241 can be adjusted according to actual needs and are not limited to the number shown in the figure.

[0033] Optionally, a flexible contact portion 2422 is provided on the side of the connecting shaft 242 close to the cup body. In this embodiment, the provision of the flexible contact portion 2422 can protect the surface of the cup body and reduce direct contact between the connecting shaft 242 and the cup body, thereby avoiding scratches or damage when the cup body is fixed. This is especially important for precision laboratory vessels that need to keep the surface intact. It can also improve stability, and the flexible contact portion 2422 can better fit the shape of the cup body, especially when there are tiny bumps or irregular shapes on the surface of the cup body. This fit enhances the friction between the cross-type reducer ring 24 and the cup body, making the entire base more stable when fixing the cup body. Preferably, the flexible contact portion 2422 is usually made of a soft and elastic material, such as rubber or silicone.

[0034] Optionally, the support rod 23 includes a first horizontal section 231 and a first vertical section 232, the end of the first horizontal section 231 is connected to the cross-type reducer ring 24, and the end of the first vertical section 232 is fixed to the slider 22; or the support rod 23 is tilted relative to the first plate 11.

[0035] In this embodiment, if the support rod 23 includes a first transverse section 231 and a first vertical section 232, as shown in FIG. Figure 2 The presence of the first transverse section 231 and the first vertical section 232 shown in the figure enables the fixed cup body, such as the lower part of the measuring cylinder, to be completely accommodated under the support rod 23. Of course, the length of the first transverse section 231 is greater than the difference between the radius of the lower part of the measuring cylinder (the lower part of the measuring cylinder, that is, the part that is inconsistent with the diameter of the measuring cylinder body) and the radius of the measuring cylinder body, and the height of the first vertical section 232 is greater than the height of the lower part of the measuring cylinder. In this way, the inner side of the cross-type reducing ring guard 24 can be closely attached to the outer wall of the cup body to provide support; or the support rod 23 is inclined relative to the first plate 11, such as Figure 4 The support rod 23 shown is a straight rod. In this case, the area formed by the inclined support rod 23 and the upper surface of the first plate 11 is still able to accommodate a graduated cylinder with a larger lower diameter and a smaller upper diameter. Based on this, it is readily apparent that by simply adjusting the length of the first horizontal segment 231 and the height of the first vertical segment 232, or adjusting the length and inclination of the support rod 23, the cup body that can be secured can also be a flask, such as an Erlenmeyer flask or a round-bottom flask.

[0036] Optional, such as Figure 2 As shown, the soft suction cup 31 includes an air outlet 310 at the top, a pit 112 is provided at the center of the first plate 11, and a center hole is opened in the middle of the pit 112. The suction cup assembly also includes a soft cover pad 32, a hard cover plate 33, a spring 34, a connecting portion 35 and a pull ring 36; the soft cover pad 32 covers the air outlet 310, the hard cover plate 33 is located above the soft cover pad 32, one end of the spring 34 is against the hard cover plate 33, and the other end of the spring 34 is against the inner side of the first plate 11; the connecting portion 35 passes through the spring 34 and the center hole, one end is connected to the hard cover plate 33, and the other end is connected to the pull ring 36, and the pull ring 36 is located in the pit 112 and stuck above the center hole.

[0037] In this embodiment, considering that it is laborious to remove the base after it is adsorbed on the desktop by the soft suction cup 31, and the soft suction cup 31 is fixed together with the second plate 12, repeated pulling may cause the soft suction cup 31 to fall off, an air vent 310 is designed on the top of the soft washing dish, and a soft cover pad 32 covers the air vent 310. The elastic force of the spring 34 causes the hard cover plate 33 to press on top of the soft cover pad 32. The shapes of the hard cover plate 33 and the soft cover pad 32 match. When the soft suction cup 31 is adsorbed on the desktop, a closed space is formed inside the suction cup, and the entire base is firmly fixed to the desktop. If you want to move the base, pull up the pull ring 36, and the connecting part 35 overcomes the elastic force of the spring 34 to drive the hard cover 33 to move upward. At this time, only the soft cover pad 32 is left covering the air outlet 310 due to air pressure. However, because the soft cover pad 32 is soft, it will deform when pressed. Therefore, after the external force is removed, the soft cover pad 32 will recover by itself. The self-recovery process plus the external force shaking will make it easier for the soft suction cup 31 to deflate from the air outlet 310, making it easier to move.

[0038] Furthermore, positioning the pull ring 36 within the recess 112 is a "foolproof" design for the base. To remove the base, the base must be clear of any cups. Compared to placing the deflation switch near the side panels of the base, positioning it in the center of the first plate 11 significantly prevents accidental contact by the user, which could cause the base to not adhere, a potential safety hazard if a cup were placed on the base. Preferably, the diameter of recess 112 is less than 1.5 cm, allowing even a 5 ml beaker (2 cm outer diameter) to be stably placed on the first plate 11.

[0039] Optionally, the soft cover pad 32 is fixedly connected to the hard cover sheet 33. In this embodiment, the fixed connection between the soft cover pad 32 and the hard cover sheet 33 can more surely pull up the soft cover pad 32 using the pull ring and release the air from the air outlet 310, which helps to ensure that when the air needs to be released, it can be operated quickly and effectively.

[0040] Optionally, the edge of the soft cover pad 32 is intermittently connected to the edge of the hard cover sheet 33. In this embodiment, the intermittent connection between the edge of the soft cover pad 32 and the edge of the hard cover sheet 33 is intended to facilitate gas release. When the hard cover sheet 33 is lifted using the pull ring 36 to release the gas inside the soft suction cup 31, if the soft cover pad 32 and the hard cover sheet 33 are completely in contact and tightly attached, the gas release will be somewhat hindered (in this case, the soft cover pad 32 and the hard cover sheet 33 are also subject to external air pressure). Using an intermittent connection, that is, the middle portion of the soft cover pad 32 is not connected to the hard cover sheet 33, and the edge of the soft cover pad 32 is not completely connected to the hard cover sheet 33, but rather a portion of the edge of the soft cover pad 32 is connected to the hard cover sheet 33. This allows the edge of the soft cover pad 32 to deform more easily when the hard cover sheet 33 is lifted, thereby more effectively opening the air outlet 310, allowing the gas to be released smoothly, improving the gas release efficiency, and thus making it easier to move the base.

[0041] Furthermore, an air hole can be set in the middle part of the hard cover plate 33, so that when lifting, the external air pressure can more easily press the middle part of the soft cover pad 32, which is more conducive to the deformation of the soft cover pad 32 when the hard cover plate 33 wants to lift part of the edge of the soft cover pad 32, and lifting it up will also save effort.

[0042] Optionally, the suction cup assembly further includes a soft cover pad fixing seat 37. A clamping portion 121 is provided on one side of the second plate 12 close to the first plate 11. The soft cover pad fixing seat 37 includes a ring foot portion 371 and a fixing ring 372. The ring foot portion 371 is clamped in the clamping portion 121, and the soft cover pad 32 is located inside the fixing ring 372. In this embodiment, Figure 7As shown, by introducing a soft cover pad fixing seat 37 and clamping its ring foot portion 371 on the clamping portion 121 of the second plate 12, a stable support structure is formed. This helps to ensure that the soft cover pad 32 maintains its position unchanged on the plane and does not translate, thereby enhancing the structural stability of the entire suction cup assembly. The matching design of the clamping portion 121 and the ring foot portion 371 enables the soft cover pad fixing seat 37 to be accurately installed in the predetermined position. This positioning accuracy helps to ensure the correct alignment between the soft cover pad 32 and the hard cover plate 33 and other related components, thereby improving the overall performance and reliability of the suction cup assembly. Moreover, such a design is also conducive to installation and disassembly. By designing the shape and size of the clamping portion 121 and the ring foot portion 371 reasonably, the installation and disassembly process can be made simpler and faster. In addition, the space inside the fixing ring 372 also provides sufficient flexibility for the installation of the soft cover pad 32.

[0043] Optional, such as Figure 8 As shown, the soft cover pad 32 includes an outer flat portion 321 and an inner recessed portion 322. The outer flat portion 321 is secured to the soft cover pad holder 37, while the inner recessed portion 322 presses against the air outlet 310. In this embodiment, the outer flat portion 321 is secured to the soft cover pad holder 37, ensuring a secure installation of the soft cover pad 32 and preventing it from shifting or falling off during use. The inner recessed portion 322 fits more snugly against the air outlet 310, forming a tight seal that prevents gas leakage from the air outlet 310 and ensures a good adsorption effect.

[0044] Optionally, the height of the pull ring 36 is smaller than the height of the recess 112. In this embodiment, when the pull ring 36 is smaller than the height of the recess 112, the pull ring 36 does not protrude from the surface of the first plate 11 during normal use. This helps prevent the experimenter from accidentally touching the pull ring 36 when handling or placing the cup, thereby preventing the base from loosening or gas release. Furthermore, the lower pull ring 36 will not interfere with the cup placed on the base, ensuring smooth experimentation.

[0045] Optionally, the connection portion 35 includes a pull rod or a pull rope. In this embodiment, if the connection portion 35 adopts a pull rod, its advantage is high strength: the pull rod is made of a rigid material, has high strength and stability, and can withstand large pulling forces. Accurate positioning: the pull rod connection is stable, and can ensure the relative position and accuracy between the various components. Good durability: the connection method of the pull rod is usually relatively strong and can maintain stable performance for a long time. If a pull rod is used, its length needs to be designed so that after assembly, the pull rod can press the hard cover plate 33 on the soft cover pad 32, and cannot make the upper surface of the pull ring protrude from the upper surface of the first plate 11. If a pull rope is used, it is only necessary to press the hard cover plate 33 on the soft cover pad 32.

[0046] Optional, such as Figure 2As shown, the second plate 12 has a recessed area 122 on a side away from the first plate 11. When the soft suction cup 31 squeezes air for suction, it is located within the recessed area 122. In this embodiment, the recessed area 122 provides additional space for the soft suction cup 31. This ensures that the soft suction cup 31 has sufficient space to deform and perform suction operations when squeezing air for suction. This helps enhance the suction effect and improves the stability and reliability of suction.
