Description

Technical Field

[0001] The utility model relates to the technical field of diagnosis, in particular to a container clamping device. Background Art

[0002] Based on the needs of automated analysis, sample conveying devices are widely used in precision instruments such as biochemical analyzers, chemiluminometers, urine analyzers, nucleic acids, and laboratory assembly line analysis systems. In the early days, a single-machine analysis and diagnosis mode was generally adopted, and only a rotating sample disk was used to provide test samples. The sample delivery amount of this sample conveying device was limited each time, which limited the sample testing speed. With the development of medical diagnostic technology, the single-machine analysis mode of the above-mentioned rotating sample disk sample supply method can no longer meet the needs of fast and efficient diagnosis. Instead, a single or multiple fully automatic diagnostic analyzers with higher efficiency are used. The analysis samples involved include ordinary samples, emergency samples, and return samples. The matching sample conveying device needs to deliver different samples to the corresponding functional units. For example, the sample containers containing emergency samples and ordinary samples are accurately transferred from the sample distribution system to different diagnostic analyzers of the sample analysis system, and the diagnostic analyzers are used to complete sample extraction and sample analysis, and the sample containers containing recovered samples are transferred to the sample recovery area in the sample distribution system. Among them, the transported samples need to be contained in sample containers such as test tubes, and the sample containers need to adapt to the transmission of the sample conveying device.

[0003] The prior art discloses the structure of a test tube rack, including a base, a placement piece for placing a test tube and a clamping mechanism for clamping the test tube on the placement piece at the upper end of the base, the placement piece adopts a U-shaped movable bar and a fixed cylinder, the clamping mechanism includes an elastic rubber strip and a movable rod, the elastic rubber strip is arranged inside the fixed cylinder, a second mounting groove is provided on the inner side of the U-shaped movable bar, the movable rod is movably installed inside the second mounting groove, a pull rope is fixedly installed at one end of the movable rod, and the other end of the pull rope is connected to the movable ring, which can solve the problem that when the test tube rack is moved, the test tube rack will be driven to move, causing the test tube to shake relative to the test tube rack. In this scheme, although the position of the elastic rubber strip can be adjusted by a screw rod, on the one hand, it is not very suitable for the conveying process of the sample conveying device, and on the other hand, the clamping stability of sample containers of different shapes and sizes is still not high, which can be further improved.

The clamping mounting block is connected to the base, and the clamping plate is connected to the clamping mounting block or the base; the clamping plate has elastic force, and the clamping surface of the clamping plate contacts the side wall of the container, and the clamping plate is arranged in multiple layers.

[0008] Furthermore, the support groove is in a cylindrical, conical, bowl-shaped or square shape.

[0009] Furthermore, the clamping piece is detachably connected to the clamping mounting block or the base.

[0010] Furthermore, the clamping sheet is an elastic steel sheet.

[0011] Furthermore, the clamping piece is provided with a guiding slope for guiding the insertion of the container.

[0012] Furthermore, the circumferential diameters of the clamping surfaces of each layer of the clamping sheets are inconsistent.

[0013] Furthermore, the clamping and mounting block is connected to a supporting block, and the supporting block is used to support the bottom of the container.

[0014] Furthermore, the circumferential diameter of the inner end of the support block matches the circumferential diameter of the edge of the support groove, so that the bottom of the container is supported by the support block, or is supported by the support groove after passing through the support block.

[0015] Furthermore, the clamping piece has more than two clamping surfaces.

[0016] Furthermore, the support block has a plurality of stepped surfaces, and freely rolling balls are arranged on the stepped surfaces. The balls are connected to springs or have elasticity themselves.

[0017] The above solution of the utility model has the following beneficial effects:

[0027] In order to make the technical problems, technical solutions and advantages to be solved by the utility model clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. In addition, the technical features involved in the different embodiments of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a locking 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 it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figure 1 , Figure 2 As shown, an embodiment of the utility model provides a container clamping device, including a base 1, wherein the base 1 is preferably cylindrical to adapt to the sample container 2 which is mostly cylindrical, such as a test tube, a sample bottle, etc. A support groove 3 is provided at the center of the base 1, and the support groove 3 is used to support and position the bottom of the container 2 so that the bottom of the container 2 is restricted. The support groove 3 can be cylindrical, conical, bowl-shaped, stepped, etc., to adapt to containers 2 with different bottom shapes. Containers 2 with different bottom shapes are as follows. Figure 3 shown.

[0031] At the same time, the base is also provided with a plurality of clamping assemblies, which are used to clamp the side walls of the container 2 so as to restrict the middle and lower parts of the container 2. Therefore, the container 2 can form a stable clamping state under the action of the clamping assemblies and the supporting grooves 3, and when the base 1 is placed on the sample conveying device, the container 2 can be conveyed stably therewith, thereby achieving the purpose of conveying the sample.

[0032] It should be noted that, for a cylindrical container 2, in order to ensure that the container 2 can be firmly clamped, at least three groups need to be set and distributed in an annular symmetry (120° relative to the center), and for a square container, four or more groups may need to be set. In this embodiment, four groups are used as an example for explanation, but not for limitation. Those skilled in the art can make comprehensive considerations and flexibly set them based on cost, weight, and firm clamping.

[0033] The clamping assembly includes a clamping mounting block 4 and a clamping sheet 5. The clamping mounting block 4 is connected to the base 1, and the clamping sheet 5 is connected to the clamping mounting block 4 or the base 1. The clamping mounting block 4 and the base 1 are detachably connected or integrally arranged, and the clamping sheet 5 is also detachably connected to the clamping mounting block 4 and the base 1 to facilitate installation and disassembly. Specifically, threaded holes are provided on the clamping mounting block 4 and the base 1, and bolt through holes corresponding to the threaded holes are provided on the clamping sheet 5. The clamping sheet 5 is fixed to the clamping mounting block 4 or the base 1 by mounting bolts 6 penetrated through the bolt through holes and the threaded holes, so that the clamping sheet 5 can clamp the container 2 at the center position.

[0034] It should be noted that the clamping sheet 5 is preferably made of an elastic steel sheet, which can firmly clamp the container 2 through the elastic force of the material. At the same time, the clamping sheet 5 is pre-bent into a specific shape so that after installation, the clamping sheets 5 of all the clamping components form a petal-shaped form, and the upper edge of the clamping sheet 5 has a guiding slope 7 inclined outward, so that the container 2 can be easily inserted and clamped. When the container 2 is inserted, the bottom of the container 2 will contact the guiding slope 7 of the clamping sheet 5, so that the clamping sheet 5 opens outward. Finally, after the container 2 is installed in place, the clamping surface 8 of the clamping sheet 5 contacts the side wall of the container 2, and the container 2 is clamped by elastic force. Among them, the guiding slope 7 and the clamping surface 8 are continuous.

[0035] As a preferred embodiment, the clamping pieces 5 of each clamping assembly in this embodiment are also arranged in multiple layers, and the diameters of the circumferences of the clamping surfaces 8 are different to accommodate the clamping of containers 2 of different sizes. The clamping surfaces 8 of the clamping pieces 5 of the bottom layer correspond to the outer circumference of the support groove 3. When the size of the container 2 matches the support groove 3, the bottom of the container 2 is directly inserted into the support groove 3 and is limited by the support groove 3. The clamping pieces 5 of the bottom layer 1 directly clamp the middle of the container 2 so that the container 2 is clamped and fixed.

[0036] When the size of the container 2 is larger than the support groove 3, as shown in FIG. Figure 4 As shown, it is necessary to rely on the upper clamping sheet 5 for clamping. As a preferred embodiment, in this embodiment, a support block 9 is provided inwardly extending from the top of the clamping mounting block 4, and the support block 9 is used to support the bottom of the container 2, so that the bottom of the container 2 is supported by the support block 9. Correspondingly, the clamping surface 8 of the upper clamping sheet 5 extends to a position higher than the support block 9, so that the side wall of the container 2 can also be clamped. Among them, the support block 9 can be a structure integrated with the clamping mounting block 4, and can also be a structure detachably connected to the clamping mounting block 4.

[0037] Based on this, the scheme in this embodiment can clamp containers 2 within two outer diameter size ranges. When the size of the container 2 is within a smaller range, the container 2 is fixed by relying on the support groove 3 and the clamping piece 5 of the bottom layer. When the size of the container 2 is within a larger range, the container 2 is fixed by relying on the support block 9 and the clamping piece 5 of the upper layer, thereby further improving the adaptability of the device.

[0038] As a preferred embodiment, the circumferential position of the inner end of the support block 9 in this embodiment is close to the circumferential position of the outer periphery of the support groove 3, so the above two outer diameter size ranges can be said to be continuous, and can clamp containers 2 within a larger range. When installing the container 2, the container 2 is moved downward relative to the center of the device by a human or a robot until the bottom of the container 2 contacts the support groove 3 or the support block 9, at which time the container can no longer move downward, indicating that the container 2 has been installed in place and is firmly clamped.

[0039] It should also be noted that the above scheme is also applicable to containers 2 with multiple sections of different sizes, that is, the bottom size of the container 2 is small, and the sizes of other positions are large. When the container 2 is clamped by the device, the bottom of the container 2 is inserted into the support groove 3 and clamped by the clamping piece 5 of the bottom layer, and the upper part of the container 2 is supported by the support block 9 and clamped by the clamping piece 5 of the upper layer, so that the container 2 can be clamped and fixed more reliably.

[0040] As another optional implementation, the shape of the bottom clamping sheet 5 in this embodiment can be further adjusted so that the bottom clamping sheet 5 has more than two clamping surfaces 8 to clamp the bottom of the container 2 at multiple positions. For containers 2 with a larger length, the clamping method using multiple clamping surfaces 8 can further improve stability and ensure reliable transportation of the container 2. Of course, the upper clamping sheet 5 can also be configured to have multiple clamping surfaces 8, etc.

[0041] As other optional embodiments, the support block 9 in this embodiment can also be provided in other forms, such as a step form, and can have multiple step surfaces to directly adapt to the step structure at the bottom of the container 2 or other positions, etc. Figure 5 At the same time, a ball 10 can be further arranged on the step surface, and the ball 10 can be relied on to make rolling contact with the container 2 during installation to avoid wear and tear between the surface of the container 2 and the step-shaped support block 9 during insertion, and at the same time, the spring inside the ball 10 or the elastic force of the ball 10 itself can be relied on to clamp.

[0042] It should be noted that, in this embodiment, the support block 9 can also be used as the clamping and mounting block 4, and the clamping piece 5 is added at the same time, that is, the support block 9 is installed in sequence in a modular manner to further adapt to containers of different sizes 2. Of course, the support block 9 should not be installed too high, resulting in a high and unstable center of gravity. Ordinary technicians in this field can install it according to actual needs.

[0043] It should be noted that, in this embodiment, the clamping device of each container 2 is an independent body, which can be transported on a sample transport device in the form of a conveyor belt. The base 1 can be configured to be compatible with the sample transport device, such as a guide fit, to further enhance the stability of the container.

[0044] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the application. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
