Abstract
Description
Technical Field
[0001] This utility model belongs to the field of placement rack technology, specifically, it relates to a test tube placement rack. Background Technology
[0002] In dental clinics, test tube holders are primarily used for storing and placing CGF membranes after their preparation. CGF membranes can reduce wound swelling, bleeding, and pain. CGF is a novel biomaterial, a fibrin gel rich in growth factors, obtained from blood through variable-speed centrifugation. Due to its readily available source, simple preparation, and safe use, platelet-rich plasma and platelet-rich fibrin have seen wide applications in oral and maxillofacial surgery, cosmetic medicine, chronic wound repair, tissue engineering, and regenerative medicine in recent years. [2-5] Clinically, CGF can be used as a diaphragm to accelerate soft tissue healing, or mixed with bone grafts to speed up new bone remodeling. [6] Domestic and international researchers [11-13] Blood is commonly collected using specific centrifuges and special plastic tubes coated with silica microparticles (SCT) for the preparation of CGF. Studies have shown that glass tubes, compared to plastic tubes, can promote fibrin recruitment and contribute to obtaining longer, thicker, and denser fibrin networks in CGF preparation. The explosive growth in the clinical application of CGF has spurred a large number of related commercial developments, including various preparation protocols, kits, and centrifuges. However, research on devices used for transport and storage during CGF membrane preparation is relatively lacking.
[0003] Currently, ordinary test tube racks are used in clinical practice. Test tubes are generally placed directly inside the holes of the rack, leaving too much space. This creates a gap between the test tubes and the holes, which can cause vibration during transportation and affect CGF preparation. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a test tube rack that can overcome or at least partially solve the above problems.
[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a test tube rack includes a support plate, a bottom plate, a middle plate, and an insert plate are respectively installed on one side of the support plate. The bottom plate, the middle plate, and the insert plate are arranged from bottom to top. A plurality of through slots are equally spaced on the top of the bottom plate, the middle plate, and the insert plate. A locking block is provided on the top of the middle plate. The locking block includes an inlet piece installed on the top of the middle plate. An abutment piece is fixedly connected to the end of the inlet piece. An outlet piece is fixedly connected to the end of the abutment piece. The abutment piece and the outlet piece are both located in the through slots opened inside the middle plate.
[0006] Preferably, a cleaning sleeve is installed in the through groove opened at the top of the insert plate. The cleaning sleeve includes a sponge sleeve located inside the through groove. A gasket is fixedly connected to the top of the sponge sleeve, and an arc-shaped opening is provided inside the gasket.
[0007] Preferably, the insert plate is composed of a plurality of concave plates and a plurality of convex plates, and the plurality of concave plates and the plurality of convex plates are fixed to each other.
[0008] Preferably, the sidewall of the support plate is provided with a plurality of dovetail grooves at equal intervals, and dovetail blocks are slidably connected inside the dovetail grooves. The dovetail blocks are respectively fixed on both sides of the bottom plate, the middle plate and the insert plate.
[0009] Preferably, a conical seat is fixedly connected to the bottom of the support plate.
[0010] Preferably, the top of the inlet piece has a slot, and a connecting screw is threaded through the inside of the slot, the connecting screw being threaded to the top of the middle plate.
[0011] Preferably, a through groove is provided on the top of the base plate, and a rubber pad is provided inside.
[0012] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:
[0013] This test tube holder, through the cooperation of the locking block, the guide plate, the contact plate, and the guide plate, can fill the gap between the hole and the test tube. This design can properly fix the surface of the test tube and prevent it from shaking and vibrating during transportation due to the gap between the test tube and the hole. Thus, it can effectively protect the contents of the test tube and will not affect the preparation of CGF. Attached Figure Description

Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0022] Example 1:
[0023] Reference Figures 1-5 A test tube holder includes a support plate 1. A base plate 2, a middle plate 3, and an insert plate 4 are respectively installed on one side of the support plate 1. The base plate 2, the middle plate 3, and the insert plate 4 are arranged from bottom to top. A plurality of through slots 5 are equally spaced on the top of the base plate 2, the middle plate 3, and the insert plate 4. A locking block 6 is provided on the top of the middle plate 3. The locking block 6 includes an inlet piece 61 installed on the top of the middle plate 3. An abutment piece 62 is fixedly connected to the end of the inlet piece 61. An outlet piece 63 is fixedly connected to the end of the abutment piece 62. The abutment piece 62 and the outlet piece 63 are both located in the through slots 5 opened inside the middle plate 3. A conical seat 11 is fixedly connected to the bottom of the support plate 1. A slot 64 is opened on the top of the inlet piece 61. A connecting screw 65 is threaded through the inside of the slot 64 and is threaded to the top of the middle plate 3. A rubber pad is provided in the through slot 5 opened on the top of the base plate 2.
[0024] In this invention, the support plate 1, side wall, bottom plate 2, middle plate 3, and insert plate 4 form three parts, which limit the bottom, middle, and top of the test tube to ensure safety during installation. Several through slots 5 are provided on the top of the bottom plate 2, middle plate 3, and insert plate 4 to accommodate different users. With the internal locking block 6 of the middle plate 3, when the test tube enters the through slot 5, the test tube will push the guide plate 61 to one side, thus fitting the test tube against the contact plate 62. The guide plate 63 applies a reaction force to the contact plate 62. When there is no pushing force at the top of the test tube, the contact plate 62 will... The guide plate 61 is tightly fitted to the surface of the test tube for fixation, and the contact plate 62, which is attached to the surface of the test tube, can also prevent vibration and effectively protect the contents of the test tube. The conical seat 11 at the bottom of the support plate 1 can improve the overall stability. The slot 64 at the top of the contact plate 62 allows the connecting screw 65 to be threaded into the slot 64 and connected to the top of the middle plate 3, thereby adjusting the distance between the guide plate 61 and the through slot 5, so as to fix test tubes of different thicknesses. The rubber pad in the through slot 5 of the base plate 2 can further support the bottom of the test tube, thus ensuring the vibration prevention effect of the bottom of the test tube.
[0025] Additional explanation: The top of the base plate 2 has a through groove 5 that does not penetrate the inside of the base plate 2, preventing the bottom of the test tube from directly passing through the through groove 5 inside the base plate 2. The through grooves 5 on the middle plate 3 and the insert plate 4 are both through-type.
[0026] Example 2:
[0027] Reference Figure 3 , Figure 4 and Figure 5 Similar to Embodiment 1, but further: a cleaning sleeve 7 is installed in the through groove 5 opened at the top of the insert plate 4. The cleaning sleeve 7 includes a sponge sleeve 71 located inside the through groove 5. A gasket 72 is fixedly connected to the top of the sponge sleeve 71. An arc-shaped opening 73 is provided inside the gasket 72. The insert plate 4 is composed of several concave plates 41 and several convex plates 42. The several concave plates 41 and several convex plates 42 are fixed to each other. Several dovetail grooves 8 are opened at equal intervals on the side wall of the support plate 1. Dovetail blocks 9 are slidably connected inside the dovetail grooves 8. The dovetail blocks 9 are fixed on both sides of the bottom plate 2, the middle plate 3 and the insert plate 4 respectively.
[0028] With the cleaning sleeve 7 in place, when the end of the test tube passes through the through groove 5 at the top of the insert plate 4, the surface of the test tube can be wiped by the sponge sleeve 71 to ensure its cleanliness. The gasket 72, positioned at the top of the insert plate 4, ensures the strength of the sponge sleeve 71 within the through groove 5. The arc-shaped opening 73 inside the gasket 72 better guides the end of the test tube, facilitating its insertion into the through groove 5. The insert plate 4, composed of a concave plate 41 and a convex plate 42, can be joined together. The test tubes are fixed in place, so that they are arranged at equal heights during installation. This prevents the test tubes from being too close together and affecting their handling, allowing for continuous operation without interference, shortening extraction time, and increasing work efficiency. The dovetail groove 8 allows the dovetail block 9 to slide within it. Since the dovetail block 9 is fixed to the side walls of the base plate 2, middle plate 3, and insert plate 4, the dovetail blocks 9 on both sides of the base plate 2, middle plate 3, and insert plate 4 can slide within the dovetail groove 8 respectively. This allows for adjustment of the height spacing between the base plate 2, middle plate 3, and insert plate 4, thus accommodating test tubes of different heights.
[0029] To further explain, the dovetail block 9 and the dovetail groove 8 are in a transitional fit, so the base plate 2, middle plate 3 and insert plate 4 will not separate from the support plate 1 without a large external force, thus preventing the test tube from falling out due to the separation of the base plate 2, middle plate 3 and insert plate 4 from the support plate 1.
[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
