[0002] Currently, in medical testing, scientific research experiments, and environmental monitoring, it is often necessary to temporarily store and transport collected samples. Most existing sample racks have fixed structures and are bulky, making them inconvenient to carry. For example, traditional sample racks are usually one-piece structures that take up a lot of space and are difficult to put into backpacks or suitcases when collecting samples, causing great inconvenience to staff. Even if some sample racks are designed with folding functions, they still have problems with loose structure and poor stability after folding, which can easily cause samples to shake and collide during transportation, affecting the integrity of the samples and the accuracy of test results. In addition, existing sample racks have limited functions in terms of sample classification and storage, and cannot meet the needs of orderly management of diverse samples. Therefore, there is an urgent need to design a portable sample rack that is compact, easy to carry, can stably store samples, and has good classification functions.

[0003] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created. It provides a portable sample holder to solve the problem that most existing sample holders have fixed structures, large volumes, and are inconvenient to carry. For example, traditional sample holders are usually of an integral structure, which takes up a lot of space and is difficult to put into backpacks or suitcases when collecting samples outside, causing great inconvenience to staff. Utility Model Content

[0004] This utility model proposes a portable sample holder, which solves the problem that most existing sample holders have fixed structures, large volumes, and are not easy to carry.

[0005] The technical solution of this utility model is implemented as follows: a portable sample rack includes a support mechanism, the main body of which is a hollow structure, and an extension bracket is inserted into the right side of the support mechanism. The extension bracket and the support mechanism are respectively provided with positioning insertion hole B and positioning insertion hole A. Both positioning holes A and B are used to install test tubes. Limiting screws are fixedly connected to the outer side of the extension bracket. There are two limiting screws, which are fixedly connected to the front and rear sides of the extension bracket in opposite directions. Limiting nuts are screwed onto the outer side of both limiting screws. In a preferred embodiment, the right side of the support mechanism is provided with a slot that matches the extension bracket, and the front and rear ends of the support mechanism are provided with guide grooves for guiding the limiting screw.

[0006] In a preferred embodiment, a limit stop bar is fixedly connected to the outer side of the support mechanism, and an extension support is fixedly connected to the right end face of the extension bracket. There are four limit stops in total, with each pair of longitudinally adjacent limit stops forming a group.

[0007] In a preferred embodiment, the support mechanism and the outer side of the extension support are fixedly connected with a rotating shaft assembly. There are four rotating shaft assemblies in total, with each pair of longitudinally adjacent rotating shaft assemblies forming a group, and the two groups of rotating shaft assemblies are arranged in a linear array.

[0008] In a preferred embodiment, a support arm assembly is installed on the outer side of both of the pivot assemblies, and a limit stop is used to limit the rotation range of the support arm assembly, wherein every two longitudinally adjacent support arm assemblies form a group.

[0009] In a preferred embodiment, each of the arm assemblies is fixedly connected to a leg assembly on its inner side. The leg assembly and the arm assemblies together form an auxiliary support structure for the support mechanism and the extension bracket.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] likeFigures 1-6 As shown, a portable sample holder includes: a support mechanism 1, the main body of the support mechanism 1 is a hollow structure, and an extension bracket 2 is inserted into the right side of the support mechanism 1. The extension bracket 2 and the support mechanism 1 are respectively provided with positioning insertion hole B201 and positioning insertion hole A1011. The interiors of positioning sockets A1011 and B201 are used to install test tube fittings 1012. The outer side of the extension bracket 2 is fixedly connected to a limiting screw 2011. There are two limiting screws 2011, and the two limiting screws 2011 are fixedly connected to the front and rear sides of the extension bracket 2 in opposite directions. The outer side of the two limiting screws 2011 is screwed with a limiting nut 2012.

[0017] The support mechanism 1 has a slot on its right side that matches the extension bracket 2. The front and rear ends of the support mechanism 1 are provided with guide grooves 101, which are used to guide the limiting screw 2011. The outer side of the support mechanism 1 is fixedly connected with a limiting stop bar 2013. The right end face of the extension bracket 2 is fixedly connected with an extension support 3. There are four limiting stops bar 2013 in total, and each pair of longitudinally adjacent limiting stops bar 2013 forms a group.

[0018] Among them, the outer side of the support mechanism 1 and the extension support 3 is fixedly connected with a rotating shaft assembly 2014. There are four rotating shaft assemblies 2014 in total. Each pair of longitudinally adjacent rotating shaft assemblies 2014 forms a group. The two groups of rotating shaft assemblies 2014 are arranged in a linear array. Each pair of rotating shaft assemblies 2014 has a support arm assembly 2015 installed on its outer side. The limiting stop bar 2013 is used to limit the rotation range of the support arm assembly 2015. Each pair of longitudinally adjacent support arm assemblies 2015 forms a group.

[0019] Each set of support arm assemblies 2015 has a support leg assembly 2016 fixedly connected to its inner side. The support leg assembly 2016 and the support arm assembly 2015 together form an auxiliary support structure for the support mechanism 1 and the extension bracket 2. The top of the extension bracket 3 has a groove, and an observation window 301 is embedded in the groove. The right side of the extension bracket 3 has indicator plates 3011 inserted in a straight array. The upper surface of the indicator plates 3011 is marked by a sticker. Each indicator plate 3011 matches each set of horizontally arranged positioning holes A1011 and B201.

[0020] When using the sample rack, first loosen the limiting nut 2012 so that the extension bracket 2 can slide relative to the support mechanism 1. Then, fully insert the extension bracket 2 into the slot on the right side of the support mechanism 1. At this time, the limiting screw 2011 slides along the guide groove 101 to the end. Then, tighten the limiting nut 2012 to fix it. Then, with the rotating shaft assembly 2014 as the axis, flip the support arm assembly 2015 upward. The support leg assembly 2016 rotates synchronously with the support arm assembly 2015 until the support arm assembly 2015 fits against the outside of the support mechanism 1 and the extension support 3. The limiting stop bar 2013 limits the rotation range of the support arm assembly 2015 to avoid excessive flipping, thereby realizing the folding of the sample rack and reducing its volume. When using the sample rack, reverse the operation to unfold the support arm assembly 2015 and the support leg assembly 2016. The support leg assembly 2016 and the support arm assembly 2015 form an auxiliary support structure to stably support the sample rack. The test tube 1012 is inserted into the positioning holes A1011 and B201 respectively. The shape of the positioning holes is adapted to the test tube 1012, which can initially fix the test tube 1012. The extension bracket 2 is inserted into the support mechanism 1 through the slot. The limiting screw 2011 passes through the guide groove 101. Tightening the limiting nut 2012 can fix the extension bracket 2 on the support mechanism 1, ensuring that the connection between the extension bracket 2 and the support mechanism 1 is stable and preventing the test tube 1012 from falling off due to the support shaking during storage. The observation window 301 at the top of the extension support 3 can be used to observe the sample status. The indicator 3011 on the right side of the extension support 3 matches the positioning holes A1011 and B201 set horizontally in each group. By attaching labels to the indicator 3011, samples in different positions can be classified and identified, making it convenient for staff to quickly identify and retrieve samples.
