Description

Technical Field

[0001] This invention relates to a test tube cart, belonging to the field of test tube clamping technology. Background Technology

[0002] In medical testing, batch testing is typically performed using automated production lines. Test tubes containing samples need to be transported along these lines. To ensure stable movement of the test tubes, a test tube cart is used. Current test tube carts often employ wire grippers. While these grippers are flexible, durable, and adaptable to different diameters, their high clamping strength can prevent the robotic arm from removing the test tubes from the cart. Some test tube carts use clamps made of plastic materials, which use the elasticity of the material to hold the test tubes. This can also accommodate test tubes of different diameters. However, this type of test tube cart has at least two problems. First, the depth of test tubes of different diameters in the cart is inconsistent, resulting in inconsistent reference heights. Second, after the cart holds a large number of test tubes with larger diameters, the deformation of the clamps will be too large, which will cause clamping failure when holding test tubes with smaller diameters. This also poses a risk of clamp fatigue fracture. Summary of the Invention

[0003] The present invention provides a test tube cart that can solve at least one of the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a test tube cart, comprising a support base and clamping components, wherein the interior of the support base is configured as a accommodating space for accommodating test tubes; the clamping components are configured in several groups and movably disposed inside the support base, wherein the clamping components are used to clamp test tubes, and are configured to change the size of the clamping space by means of movement.

[0005] As a preferred embodiment, the test tube cart further includes a clamping component, which is sleeved on the outside of the clamping component.

[0006] As a preferred embodiment, the clamping element is an elastic body, which can be a spring or elastic rubber.

[0007] As a preferred embodiment, the support includes a receiving portion and a supporting portion distributed vertically, with a partition connecting the receiving portion and the supporting portion. The partition is provided with connecting holes for the clamping members to pass through, and the number of connecting holes matches the number of clamping members.

[0008] As a preferred embodiment, the clamping member includes a clamping seat and a clamping rod connected to one end of the clamping seat. The clamping rod passes through a connecting hole to the receiving portion, and the other end of the clamping seat is rotatably connected to a first column disposed on the lower end face of the partition. By rotating the clamping seat relative to the first column, the clamping rod is driven to move within the connecting hole in a direction closer to or away from the axis of the receiving portion.

[0009] As a preferred embodiment, the inner diameter of the connecting hole is larger than the outer diameter of the clamping rod, so that the clamping rod has a certain amount of room to move within the connecting hole. At the same time, the connecting hole can also limit the rotation space of the clamping seat.

[0010] As a preferred embodiment, the test tube cart further includes a limiting plate, which is movably connected to the bottom end of the clamping member and is configured to drive the clamping members to move synchronously.

[0011] As a preferred embodiment, the limiting plate has a first slot that matches the first column, and the first slot is arc-shaped. A second column is also connected to the bottom end of the clamping seat and the opposite side of the clamping rod. The limiting plate has a second slot that matches the second column, and the second slot is straight. The second column can slide within the second slot. When the test tube is inserted into the receiving part, one end of any clamping rod can move about the first column as the center of rotation, moving away from the axis of the receiving part. This causes the corresponding second column to move synchronously in the same direction. The second column slides within the second slot, pushing the limiting plate to rotate. Simultaneously, other second slots push the corresponding second column to slide, causing the corresponding clamping rod to move synchronously, thus achieving synchronous movement of all clamping rods.

[0012] As a preferred embodiment, the first column passes through the first slot, and the first column is provided with an annular groove near the bottom for connecting fasteners to prevent the limiting plate and clamping member from falling off the bottom of the support.

[0013] As a preferred embodiment, the bottom of the support base is also connected to a fixed base, and the fixed base is further provided with a positioning part for installing the positioning magnetic sheet.

[0014] The test tube cart provided by this invention has the following beneficial effects:

[0015] 1) The test tube trolley provided by the present invention uses a clamping member that is movably connected to the first column inside the support seat. The clamping rod can move towards or away from the axis of the receiving part. By using the clamping member to clamp the test tube, the problem of easy fatigue and breakage of the clamping claw or weakening of the clamping force caused by the plastic clamping of the clamping claw in the traditional technology can be avoided. Moreover, test tubes of different diameters are at the same reference height in the trolley.

[0016] 2) By using an elastomer to clamp the test tube with the clamping rod, the clamping force is appropriate and will not cause the problem of excessive clamping strength caused by the use of steel wire clamps in traditional technology.

[0017] 3) By using a limiting plate to act on the clamping parts, the clamping rods move synchronously. Combined with the action of the clamping parts, it can be ensured that the position of the test tube in the trolley is the geometric center of the trolley. Attached Figure Description

Detailed Implementation

[0028] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] To facilitate understanding of the present invention by those skilled in the art, specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0030] like Figures 1-3 As shown, this embodiment discloses a test tube cart, including a support base 1, which is generally hollow, forming an internal space for accommodating test tubes. Several clamping members 2 are arranged circumferentially inside the support base 1, with their upper ends extending from the top of the support base 1 to clamp and fix the test tubes entering the accommodating space. The clamping members 2 are movably disposed inside the support base 1, and the size of the clamping space can be changed by the movement of the clamping members 2.

[0031] For details, see Figures 4-6 The support 1 includes a receiving portion 101 and a supporting portion 102, both of which are hollow cylinders. The receiving portion 101 is connected above the supporting portion 102, and the two are preferably integrally formed and coaxially arranged. The aforementioned receiving space is located inside the receiving portion 101, and the internal structure of the supporting portion 102 serves as the movable space for the clamping member 2. The diameter of the supporting portion 102 is slightly larger than the diameter of the receiving portion 101. A partition 3 connects the receiving portion 101 and the supporting portion 102, separating them. The partition 3 has connecting holes 4 for the clamping member 2 to pass through. The number of connecting holes 4 corresponds to the number of clamping members 2. The clamping member 2 is movably disposed inside the supporting portion 102, with its upper end penetrating from the partition 3 into the receiving portion 101. The number of clamping members 2 can be specifically set according to requirements, but to ensure clamping stability, at least three sets should be provided.

[0032] The support portion 102 has a number of first pillars 5 corresponding to the number of clamping members 2. These first pillars 5 are fixedly connected to the lower end face of the partition 3 and are spaced apart between the connecting holes 4. The first pillars 5 extend from the partition 3 towards the bottom of the support portion 102, and the clamping members 2 are movably connected to the corresponding first pillars 5. For more details, see... Figure 7The clamping member 2 includes a clamping rod 201 and a clamping seat 202 connected to the bottom end of the clamping rod 201. The clamping seat 202 is generally arc-shaped, and its two ends are further designated as a first connecting end 2021 and a second connecting end 2022. The clamping rod 201 is fixedly connected to the upper end face of the first connecting end 2021. The second connecting end 2022 has a hole that passes through the clamping seat 202. The inner diameter of the hole matches the outer diameter of the first column 5. The clamping seat 202 is sleeved around the first column 5 through the hole and is rotatably connected to the first column 5. Furthermore, the clamping seat 202 abuts against the lower end face of the partition 3, and the clamping rod 201 passes through the connecting hole 4 into the receiving part 101. The inner diameter of the connecting hole 4 is larger than the outer diameter of the clamping rod 201, so that the clamping rod 201 has a certain amount of room to move within the connecting hole 4. At the same time, the connecting hole 4 can also limit the rotation space of the clamping seat 202. The rotation of the clamping seat 202 relative to the first column 5 causes the clamping rod 201 to move in the connecting hole 4 toward or away from the axis of the receiving part 101. Correspondingly, when the test tube is inserted into the receiving part 101 along the clamping rod 201, the clamping rod 201 can move away from the axis of the receiving part 101, causing the clamping seat 202 to rotate to provide motion support.

[0033] Understandably, when the test tube is placed in the receiving part 101, due to the rotatable connection between the clamping seat 202 and the first column 5, the clamping rod 201 can expand outward to provide space for the test tube. However, the movable state of the clamping rod 201 prevents it from stably clamping the test tube, resulting in the test tube wobbling. See again. Figure 2 The test tube cart provided in this embodiment also includes a clamping member 7, used to automatically clamp the test tubes with each clamping rod 201. In this embodiment, the clamping member 7 is a ring-shaped elastic body, sleeved on the outside of each clamping rod 201. When the test tube is placed inside the receiving part 101, the clamping rod 201 expands outward, causing the elastic body to be in a stretched state. When the test tube is in place, the elastic body retracts, which can drive each clamping rod 201 to clamp the test tube, thereby clamping the test tube. Specifically, a locking groove is provided on the outside of the clamping rod 201. The locking groove is located near the upper end of the clamping rod 201 and protrudes outside the receiving part 101. The clamping member 7 is embedded in the locking groove. The elastic body can be made of elastic materials such as springs or elastic rubber, preferably springs with good elasticity and not easily aged or deformed.

[0034] In this embodiment, by employing a clamping member 2 movably connected to the first column 5 inside the support 1, the clamping rod 201 can move towards or away from the axis of the receiving part 101. Using this clamping member 2 to clamp the test tube can avoid the problems of easy fatigue and breakage of the clamping claws or weakening of clamping force caused by the plastic clamping of the test tube by the claws in the traditional technology. Furthermore, in this embodiment, an elastic body is used to act on the clamping rod 201 to hold the test tube tightly. The clamping force is appropriate and will not cause the problem of excessive clamping strength caused by the use of steel wire claws in the traditional technology. Moreover, test tubes of different diameters are at the same reference height in the trolley.

[0035] In another preferred embodiment, see Figure 4 The inner wall of the receiving part 101 is connected to multiple sets of support blocks. The support blocks 11 are spaced apart between each connecting hole 4. The support blocks 11 are used to support the test tube from the bottom of the test tube, making the test tube more stable. The support block 11 has an embedding surface 111 on the side facing the axis of the receiving part 101. The embedding surface 111 contacts the bottom end of the test tube and matches the shape of the bottom end of the test tube.

[0036] Combination Figure 3 and Figure 8 To ensure that the test tube insertion receiving part 101 is centered, in another embodiment, the test tube cart also includes a limiting plate 9, which is movably connected to the bottom end of each clamping seat 202. Specifically, the first column 5 passes through the clamping seat 202 and extends out of the bottom end of the clamping seat 202; as mentioned above, the clamping rod 201 is connected to the upper end face of the first connecting end 2021 of the clamping seat 202, and a second column 8 is also connected to the lower end face of the first connecting end 2021, that is, the bottom end of the clamping seat 202. Unlike the first column 5, the length of the second column 8 is shorter, and it can be approximately the same as the length of the first column 5 extending out of the bottom end of the clamping seat 202.

[0037] Furthermore, the limiting plate 9 is circular in shape and has first slots 901 that match each of the first pillars 5. The number of first slots 901 is equal to the number of first pillars 5. The first slots 901 are arc-shaped and evenly distributed along the circumference of the limiting plate 9 at its edge. The first pillars 5 are inserted into the corresponding first slots 901. Through the cooperation of the first pillars 5 and the first slots 901, the relative position of the limiting plate 9 is limited. At the same time, the limiting plate 9 can rotate slightly relative to the first pillars 5. Furthermore, the limiting plate 9 also has second slots 902 that match each of the second pillars 8. The number of second slots 902 is equal to the number of second pillars 8. The second slots 902 are straight and evenly distributed along the circumference of the limiting plate 9. One end of the second slot 902 is close to the axis of the limiting plate 9, and the other end extends to the edge of the limiting plate 9. The second column 8 can slide within the second slot 902. That is, when the test tube is inserted into the receiving part 101 along the clamping rod 201, the first connecting end 2021 where any clamping rod 201 is located can move away from the axis of the receiving part 101 with the first column 5 as the center of rotation, and drive the corresponding second column 8 to move synchronously in the same direction. The second column 8 slides in the second slot 902, and pushes the limiting plate 9 to rotate. At the same time, the other second slots 902 push the corresponding second column 8 to slide, and drive the corresponding clamping rod 201 to move synchronously, thereby realizing the synchronous movement of all clamping rods 201. When the test tube is in place, the clamping member 7 drives each clamping rod 201 to move synchronously in the center, and at the same time drives the test tube to move in the center, ensuring that the static position of the test tube in the receiving part 101 is the geometric center of the support seat 1. The test tube cart provided in this embodiment can realize the automatic centering and positioning of the test tube by using the limiting plate 9 without other auxiliary positioning facilities.

[0038] See you again Figure 3 To ensure that the limiting plate 9 and the clamping member 2 do not fall off from the bottom of the bearing seat 1, in this embodiment, the first column 5 passes through the first slot 901 by a predetermined length, and the first column 5 is provided with an annular groove 501 along the circumferential direction near the bottom. The annular groove 501 is used to connect fasteners. The fasteners can be components such as snap rings and retaining rings. It is understood that there should be a certain gap between the fasteners and the bottom of the limiting plate 9 to avoid restricting the rotation of the limiting plate 9.

[0039] In another preferred embodiment, the test tube cart further includes a cover 10 that snaps onto the top of the receiving portion 101. Specifically, the receiving portion 101 has several protrusions on its side near the top, and the cover 10 has notches that mate with the protrusions. The center of the cover 10 is hollow, allowing the clamping rod 201 to pass through. The cover 10 not only protects the clamping member 7 but also ensures the overall aesthetics of the cart.

[0040] Combination Figure 1 and Figure 9 In this embodiment, a fixed base 6 is also connected to the bottom of the support 1. The fixed base 6 is connected to the bottom end of the support part 102 and can support the entire trolley. Furthermore, the fixed base 6 is provided with two positioning parts inside. The positioning parts are used to install positioning magnetic pieces and include a positioning seat and a fixing block connected circumferentially along the positioning seat. The two positioning parts are a first positioning part 601 for positioning larger magnetic pieces and a second positioning part 602 for positioning smaller magnetic pieces. The first positioning part 601 includes a first positioning seat and a first fixing block. The first fixing block is connected to the inner wall of the fixed base 6. The second positioning part 602 is disposed inside the first positioning seat.

[0041] For example, the test tube is clamped by an external motion mechanism and inserted into the receiving part 101 of the test tube cart. The state of the clamping member 2 changes from an inward state without a test tube to an outward state with a test tube. The clamping member 7 provides clamping force to clamp and fix the test tube. When the test tube is removed, the clamping member 7 drives the clamping member 2 to return to the state without a test tube, and the cycle repeats until the test tube is clamped again.
