Description

Technical Field

[0001] The invention relates to the technical field of placement racks, in particular to a magnetic dropper rack and a matching dropper. Background Art

[0002] The rubber-tipped dropper cannot be inverted or placed flat on the table. When performing multi-sample and multi-step experimental procedures on a daily basis, it is difficult to find a suitable temporary storage device for the rubber-tipped dropper, and the droplets in the dropper often flow back or the dropper is contaminated; at the same time, the temporarily stored droppers are also easily confused, resulting in cross-contamination between samples.

[0003] For example, publication number "CN217313498U" discloses "a storage rack for rubber-tipped droppers for sampling in biological experiments", including a rotating rack, a supporting rack and a test tube clamp; the rotating rack and the supporting rack are threadedly matched for rotation; the test tube clamp and the rotating rack are rotatably matched; the peripheral side surface of the connecting rod is located at the bottom and is linearly distributed and fixedly connected to a telescopic adjustment rod; the peripheral side surface of the telescopic adjustment rod is fixedly connected to a support rod near one end; a funnel is fixedly connected to one end of the support rod; and the test tube clamp holds a collection test tube.

[0004] However, in actual applications, this type of dropper storage bracket needs to hold droppers of specified sizes. When the sizes do not match, the rubber-tipped dropper may fall off or get stuck. Therefore, the user needs to carefully compare the sizes when placing the dropper, which affects operational efficiency. Summary of the invention

[0005] In view of the problem that the prior art mentioned in the background technology has the problem that the placement operation is cumbersome and cannot adapt to droppers of different specifications, the present invention provides a magnetic dropper rack and a matching dropper, which can simplify the operation steps of placing a rubber-tipped dropper during use and can adapt to the placement of rubber-tipped droppers of different specifications.

[0006] To achieve the above objectives, the present invention adopts the following technical solutions.

[0007] A magnetic dropper stand and a matching dropper, comprising: a placement rack assembly, wherein a suspended bracket is provided on the placement rack assembly, and a magnetic unit is provided on the suspended bracket; a dropper assembly, wherein the dropper assembly comprises a rubber cap, and an adsorption unit is provided on the rubber cap; and the magnetic unit can be magnetically connected to the adsorption unit. In the present application, the magnetic unit is magnetically connected to the adsorption unit, so that the dropper assembly is fixed to the suspended bracket only by the magnetic effect, so that there are no other limiting constraints around the dropper assembly, so that the placement of the dropper unit becomes more flexible, the risk of interference is reduced, and the efficiency of taking is improved, and the dropper assembly and the placement bracket are not incompatible. The magnetic unit and the adsorption unit can be a combination of a magnet and an iron block, or a combination of a magnet and a magnet, and are set accordingly according to actual usage requirements in actual applications.

[0008] Preferably, an energized slide rail is provided in the suspended bracket, and a magnetic unit is slidably connected in the energized slide rail. The magnetic unit is an electromagnetic component, and the magnetic unit includes a contact position arranged near the bottom of the energized slide rail. A connection potential is arranged at the bottom of the energized slide rail. When the dropper assembly contacts and squeezes the magnetic point, the magnetic unit moves toward the connection potential side, the contact position abuts the connection potential, and the electromagnetic component generates magnetic attraction to the dropper assembly. At the moment of placing and taking the dropper assembly, since it is necessary to overcome the magnetic connection force between the magnetic unit and the adsorption unit, a large inertia or impact force will be generated on the dropper assembly at the moment of separation and adsorption, affecting the stability of taking and placing. Therefore, in order to avoid separation by overcoming the magnetic force and adsorbing the dropper assembly by instantaneous magnetic force, in the present application, the magnetic unit is slidably connected in a specially provided energized slide rail, and the magnetic unit is configured as an electromagnetic component. Through the sliding connection of the magnetic unit, the on and off between the contact position and the connection potential can be controlled, and the sliding control of the magnetic unit is controlled by taking the dropper assembly; for example: the contact position of the magnetic unit and the connection potential are disconnected, and the magnetic unit is in a state of being separated from the power supply. When the staff clamps the dropper assembly and places it on the suspended bracket, the dropper assembly will abut the magnetic unit, and due to the pressing effect of the staff and the elasticity of the rubber head cap itself, the magnetic unit will be squeezed to move in the energized slide rail. In this process, even if the dropper assembly contacts the magnetic unit, the magnetic unit will not move. Unit, but since the magnetic unit is in a state of being disconnected from the power supply, there is no magnetic attraction effect between the magnetic unit and the adsorption unit. The magnetic unit can only produce a magnetic attraction effect when the contact position is in contact with the ground potential, and then produce magnetic attraction to the adsorption unit. In the process of generating magnetic attraction, since the dropper assembly has already abutted against the magnetic unit at this time, even if the magnetic attraction effect is generated at this time, the dropper assembly will produce relative movement, so no impact force can be generated on the dropper assembly, thereby ensuring the stability during the placement process; and when the dropper assembly needs to be taken out, since the dropper assembly is adsorbed on the magnetic unit at this time, when the dropper assembly is pulled out, the magnetic unit can be synchronously driven to separate from the contact position. Therefore, the staff does not need to overcome the magnetic attraction when taking the dropper assembly, but only needs to drive the magnetic unit to move in the energized slide rail to disconnect the magnetic attraction effect of the magnetic unit, thereby avoiding a large inertia effect in the process of taking the dropper assembly, thereby ensuring the stability of the dropper assembly during the taking and storage process.

[0009] Preferably, the magnetic unit includes an integral shell, the integral shell is slidably connected in the energized slide rail, the contact position is connected to the integral shell, an iron core is connected in the integral shell, a coil group is sleeved on the iron core, the coil group is connected to the contact position, and the iron core includes a magnetic portion protruding from a suspended bracket. The magnetic unit includes an integral shell, wherein the interior of the integral shell is designed with a contact and a coil group, the integral shell is slidably connected to the energized slide rail, so the integral shell can synchronously drive the iron core and the coil group to move synchronously, and the contact position is set on the whole, so that the magnetic attraction effect of the magnetic unit can be controlled by the movement of the magnetic unit.

[0010] Preferably, a limiting slide rail is provided in the suspended bracket, the limiting slide rail is slidably connected to a pressing rod, a wedge-shaped limiting block is provided in the suspended bracket at the end of the pressing rod, and a plurality of limiting grooves corresponding to the wedge-shaped limiting blocks are provided on the magnetic unit. When the dropper assembly abuts against the magnetic unit, the fingers holding the dropper assembly synchronously abut against the pressing rod, and an elastic member is connected to the wedge-shaped limiting block. The lever is pressed against the bottom edge of the holder and the grip is engaged when the user presses the lever, causing the user to move the lever back and forth, thereby releasing the user from the gripping action. The movement of the pressure rod and the sliding of the magnetic unit are almost synchronized; and when the dropper assembly needs to be taken out, the staff also needs to place two fingers on both sides of the dropper assembly to produce a pressing effect on the pressing rod, and the oblique limit block is disengaged from the limit groove. When the finger drives the dropper assembly to move and simultaneously drives the magnetic unit to move, the finger will gradually separate from the pressing rod, but at this time the wedge-shaped limit block has been misaligned with the limit groove, so it cannot be inserted into the limit groove to affect the movement of the magnetic unit. When the magnetic unit moves into place, it can be reset and inserted by the elastic member. Therefore, it is preferred to set the end of the wedge-shaped limit block and the notch of the limit groove to an arc surface or an inclined surface structure that is easier to engage, thereby improving the smoothness; the above structure can ensure the fixing effect of the magnetic unit at a specific position, avoid the movement of the magnetic unit due to shaking or movement, and change the state of the potential connection, and at the same time, the action of taking out the dropper assembly can be placed synchronously to unlock and lock, without the need for additional actions, and the operation is more convenient and quick.

A waste liquid tank is provided below the suspended bracket, through which waste liquid dripping from the dropper assembly placed on the suspended bracket can be recovered. The size of the waste liquid tank is set to be the same as that of the base plate seat, thereby increasing the recovery area and the waste liquid collection range.

[0015] Preferably, the suspension bracket is provided with placement positions on both sides. The placement positions are respectively placed on both sides of the suspension bracket, thereby improving the storage effect, avoiding the mutual interference effect of the dropper assembly, and increasing the storage capacity of the dropper assembly.

[0016] Preferably, the suspended bracket includes a placement position, and the magnetic unit is rotatably connected to the placement position. The magnetic unit is rotated and connected to the placement position, so that after the magnetic unit is connected to the adsorption unit, the dropper assembly can rotate relatively around the magnetic unit, so that it can adapt to the picking and placing at various angles, and the magnetic unit can rotate, so that the dropper assembly can be kept vertically downward after being placed in the placement position, so as to ensure that the dropper assembly is neatly arranged; and because the dropper assembly can move according to the user's picking and placing angle, and at the same time drive the magnetic unit to move synchronously through the magnetic effect, there is no relative movement between the magnetic unit and the adsorption unit during the picking process, so that when the adsorption unit is embedded in the rubber head cap, the wear of the rubber head cap is avoided, so that when it is rotated to a suitable force angle, the magnetic unit can be directly separated from the adsorption unit without wearing the rubber head cap, thereby protecting the service life of the dropper assembly; at the same time, during the placement process, it can be placed more freely without having to keep the dropper assembly vertically downward. After the placement is completed, the rotatable magnetic unit rotates under the gravity of the dropper assembly, so as to adaptively ensure that the dropper assembly is vertically downward.

[0053] The suspended bracket 11 includes a placement position 13, and the magnetic unit 12 is rotatably connected to the placement position 13. The magnetic unit 12 is rotatably connected to the placement position 13, so that after the magnetic unit 12 is connected to the adsorption unit 42, the dropper assembly 4 can rotate relatively around the magnetic unit 12, so that it can adapt to the taking and placement at various angles, and the magnetic unit 12 can rotate, so that the dropper assembly 4 can be placed in the placement position 13. The vertical downward setting ensures that the dropper assembly 4 is neatly arranged; and because the dropper assembly 4 can move according to the user's taking and placing angle, and at the same time drive the magnetic unit 12 to move synchronously through the magnetic effect, the magnetic unit 12 can be made to move synchronously during the taking process. There is no relative movement between the magnetic unit 12 and the adsorption unit 42, so that when the adsorption unit 42 is embedded in the rubber head cap 41, wear on the rubber head cap 41 is avoided, so that when it is rotated to a suitable force angle, the magnetic unit 12 can be directly separated from the adsorption unit 42 without wearing the rubber head cap 41, thereby protecting the service life of the dropper assembly 4; at the same time, during the placement process, it can be placed more freely without having to keep the dropper assembly 4 vertically downward. After the placement is completed, the rotatable magnetic unit 12 rotates under the drive of the gravity of the dropper assembly 4, thereby adaptively ensuring that the dropper assembly 4 is vertically downward.

[0054] A rotating bearing 14 is provided on the placement position 13, and the rotating bearing 14 is sleeved with the magnetic unit 12, so that the magnetic unit 12 can rotate relative to the suspended bracket 11. By providing the rotating bearing 14, the placement flexibility of the magnetic unit 12 can be improved, and friction loss can be avoided during the early rotation of the magnetic unit 12.

[0055] The present embodiment also includes: a placement rack assembly 1, on which a suspended bracket 11 is provided, and a magnetic unit 12 is provided on the suspended bracket 11; a dropper assembly 4, which includes a rubber cap 41, and on which an adsorption unit 42 is provided; and the magnetic unit 12 can be magnetically connected to the adsorption unit 42. In the present application, by magnetically connecting the magnetic unit 12 to the adsorption unit 42, the dropper assembly 4 is fixed to the suspended bracket 11 only by the magnetic effect, so that there are no other limiting constraints around the dropper assembly 4, so that the placement of the dropper unit becomes more flexible, the risk of interference is reduced, and the efficiency of taking is improved, and the dropper assembly 4 will not be incompatible with the placement rack, wherein the magnetic unit 12 and the adsorption unit 42 can be a combination of a magnet and an iron block, or a combination of a magnet and a magnet, and are set accordingly according to actual usage requirements in actual applications.

[0056] The placement frame assembly 1 includes a base plate seat 2, and the base plate seat 2 is connected to the suspended bracket 11. By arranging the base plate seat, the stabilizing effect of the suspended bracket 11 can be increased, and the placement stability of the dropper assembly 4 can be improved.

[0057] A plurality of protrusions 21 are arranged in the middle of the base plate seat 2, and the suspended bracket 11 includes a vertical bracket 111. A plurality of connection holes 112 are arranged at the bottom of the vertical bracket 111, and the connection holes 112 are engaged with the connection protrusions 21. The suspended bracket 11 is placed in the middle of the base plate seat 2, so that the base plate seat 2 can support the suspended bracket 11 uniformly, and the connection between the protrusions 21 and the connection holes 112 can improve the assembly efficiency.

[0058] The rack assembly 1 includes a waste liquid tank 3, which is placed below the suspended bracket 11. The waste liquid tank 3 is arranged below the suspended bracket 11, and the waste liquid dripping from the dropper assembly 4 placed on the suspended bracket 11 can be recovered through the waste liquid tank 3. The size of the waste liquid tank 3 is set to be the same as that of the bottom plate seat 2, so that the recovery area can be increased and the waste liquid collection range can be increased.

[0059] The bottom of the waste liquid tank 3 is connected to a base plate seat 2, the base plate seat 2 is connected to the suspension bracket 11, a convex strip 22 is arranged on the side of the base plate seat close to the waste liquid tank 3, and a snap-in groove 31 is arranged on the side of the waste liquid tank 3 close to the base plate seat, and the snap-in groove 31 snaps and connects the convex strip 22. The convex strip 22 is arranged on the base plate seat 2, wherein the convex strip 22 protrudes upward, and correspondingly, the snap-in groove 31 is arranged at the bottom of the waste liquid tank 3, and the snap-in connection between the snap-in connection between the snap-in connection 31 and the convex strip 22 can ensure the fixing effect of the waste liquid tank 3 relative to the base plate seat 2, and avoid the waste liquid tank 3 from losing the restraining effect and causing displacement, and the snap-in connection between the convex strip 22 and the snap-in connection between the snap-in connection 31 can achieve the effect of quick assembly.

[0060] Both sides of the suspended bracket 11 are provided with placement positions 13. The placement positions 13 are respectively placed on both sides of the suspended bracket 11, thereby improving the storage effect, avoiding the mutual interference effect of the dropper assembly 4, and improving the storage capacity of the dropper assembly 4.

[0061] Embodiment 5: like Fig. 9As shown, a powered slide rail 18 is provided in the suspended bracket 11, and a magnetic unit 12 is slidably connected in the powered slide rail 18. The magnetic unit 12 is an electromagnetic component. The magnetic unit 12 includes a contact position 121 arranged near the bottom of the powered slide rail 18. A connection potential 181 is arranged at the bottom of the powered slide rail 18. When the dropper assembly contacts and squeezes the magnetic point, the magnetic unit 12 moves toward the connection potential 181, and the contact position 121 abuts against the connection potential 181, and the electromagnetic component generates magnetic attraction to the dropper assembly. At the moment of placing and taking the dropper assembly, since it is necessary to overcome the magnetic connection force between the magnetic unit 12 and the adsorption unit, a large inertia or impact force will be generated on the dropper assembly at the moment of separation and adsorption, affecting the stability of taking and placing. Therefore, in order to avoid separation by overcoming the magnetic force and adsorbing the dropper assembly by the instantaneous magnetic force, in the present application, the magnetic unit 12 is slidably connected to a specially provided energized slide rail 18, and the magnetic unit 12 is configured as an electromagnetic component, and the touch can be controlled by the sliding connection of the magnetic unit 12. The contact point 121 and the connection potential 181 are connected and disconnected, and the sliding control of the magnetic unit 12 is controlled by taking the dropper assembly; for example: the contact point 121 and the connection potential 181 of the magnetic unit 12 are disconnected, and the magnetic unit 12 is in a state of being disconnected from the power supply. When the staff clamps the dropper assembly and places it on the suspended bracket 11, the dropper assembly will abut the magnetic unit 12, and due to the pressing effect of the staff and the elasticity of the rubber head cap itself, the magnetic unit 12 will be squeezed to move in the energized slide rail 18. In this process, even if the dropper assembly The magnetic unit 12 is in contact with the magnetic unit 12, but since the magnetic unit 12 is disconnected from the power supply, there is no magnetic attraction effect between the magnetic unit 12 and the adsorption unit. Only when the contact point 121 is in contact with the grounding potential 181, the magnetic unit 12 can produce a magnetic attraction effect, thereby generating magnetic attraction to the adsorption unit. In the process of generating magnetic attraction, since the dropper assembly has already abutted against the magnetic unit 12, even if a magnetic attraction effect is generated at this time, the dropper assembly will generate relative movement, so no impact force will be generated on the dropper assembly, thereby ensuring that the dropper assembly is placed properly. and when the dropper assembly needs to be taken out, since the dropper assembly is adsorbed on the magnetic unit 12 at this time, when the dropper assembly is pulled out, the magnetic unit 12 can be synchronously driven to separate from the contact position 121. Therefore, the staff does not need to overcome the magnetic attraction when taking the dropper assembly, but only needs to drive the magnetic unit 12 to move in the energized slide rail 18 to disconnect the magnetic attraction of the magnetic unit 12, thereby avoiding a large inertia effect in the process of taking the dropper assembly, thereby ensuring the stability of the dropper assembly during the taking and storage process.

[0062] 2. The magnetic unit 12 includes an integral shell 122, which is slidably connected to the energized slide rail 18, and the contact position 121 is connected to the integral shell 122. An iron core 123 is connected to the integral shell 122, and a coil group 124 is sleeved on the iron core 123. The coil group 124 is connected to the contact position 121, and the iron core 123 includes a magnetic attraction portion 125 protruding from the suspended bracket 11. The magnetic unit 12 includes an integral shell 122, wherein the integral shell 122 is designed with a coil group 124 inside. The integral shell 122 is slidably connected to the energized slide rail 18, so that the integral shell 122 can synchronously drive the iron core 123 and the coil group 124 to move synchronously, and the contact position 121 is set on the integral shell, so that the magnetic attraction effect of the magnetic unit 12 can be controlled by the movement of the magnetic unit 12 to turn on and off.

[0063] Embodiment 6: like Fig.10As shown, a limiting slide rail 19 is provided in the suspended bracket 11, and the limiting slide rail 19 is slidably connected to a pressing rod 191. A wedge-shaped limiting block 192 is provided in the suspended bracket 11 at the end of the pressing rod 191, and a plurality of limiting grooves 126 corresponding to the wedge-shaped limiting block 192 are provided on the magnetic unit 12. When the dropper assembly abuts against the magnetic unit 12, the fingers holding the dropper assembly synchronously abut against the pressing rod 191, and an elastic member 193 is connected to the wedge-shaped limiting block 192. A limit slide rail is also provided in the suspended bracket 11, wherein the position of the limit slide rail 19 is opposite to the position of the fingers on both sides of the staff when taking the dropper assembly. Therefore, when taking and placing the dropper assembly, the fingers on both sides of the staff will touch and squeeze the pressing rod 191, and the pressing rod 191 moves in the limit slide rail 19 to drive the wedge-shaped limit block 192 to move, thereby disengaging the wedge-shaped limit block 192 from the limit groove 126 on the magnetic unit 12. At this time, the magnetic unit 12 can be synchronously moved toward the bottom of the powered slide rail 18 by the pressing force, and the magnetic unit 12 is powered. Therefore, during use, the finger can synchronously contact the pressing rod 191 and the dropper assembly can contact the magnetic unit 12. When the pressing rod 191 is pressed, the wedge-shaped limit block 192 may not be completely out of the limit groove 126. At this time, since the rubber head cap of the dropper assembly is retractable, it can be deformed accordingly. After the wedge-shaped limit block 192 is completely out of the limit groove 126, the magnetic unit 12 can slide by relying on the pressure of the staff and the elastic reset of the rubber head cap. Since the wedge-shaped limit block 192 has a very small disengagement stroke and the elastic stiffness coefficient of the elastic member 193 is The pressure rod 191 is relatively small, so the movement of the pressing rod 191 and the sliding of the magnetic unit 12 are almost synchronized. When the dropper assembly needs to be taken out, the staff also needs to place two fingers on both sides of the dropper assembly to produce a pressing effect on the pressing rod 191, so that the oblique limit block is disengaged from the limit groove 126. When the finger drives the dropper assembly to move and simultaneously drives the magnetic unit 12 to move, the finger will gradually separate from the pressing rod 191. However, at this time, the wedge-shaped limit block 192 has been misaligned with the limit groove 126, so it cannot be stuck in the limit groove 126 to affect the movement of the magnetic unit 12. Only after the element 12 moves into place can it be reset and locked in by the elastic member 193. Therefore, it is preferred to set the end of the wedge-shaped limit block 192 and the notch of the limit groove 126 to an arc surface or a slope structure that is easier to engage, so as to improve the smoothness. The above structure can ensure the fixing effect of the magnetic unit 12 in a specific position, avoid the movement of the magnetic unit 12 due to shaking or movement, and the change of the state of the potential connection 181. At the same time, the action of placing and taking the dropper assembly can be synchronized to unlock and lock, without the need for additional actions, and the operation is more convenient and quick.
