DETAILED DESCRIPTION

[0015] The utility model is further described in detail below through specific implementation methods:

[0016] like Figure 1 and Figure 2 As shown, an embodiment of the utility model proposes a test tube fixing structure for a full-temperature oscillator spring grid, comprising a bottom support portion 1, a connecting sleeve 2 and a hanging portion 3; wherein the connecting sleeve 2 is connected to the bottom support portion 1 and is coaxially spaced, and two clamping blocks 4 with adjustable spacing are arranged in the connecting sleeve 2; the hanging portion 3 is connected to the outer wall of the connecting sleeve 2 and is used to be hung on the spring grid 5.

[0017] The test tube fixing structure is hung on the spring grid 5 through the hanging part 3, and then the test tube is inserted between the two clamping blocks 4 to clamp and fix. At the same time, the bottom of the test tube is supported on the bottom supporting part 1 to stably fix the test tube on the spring grid 5 for testing; here, the distance between the two clamping blocks 4 is adjustable, so that test tubes of different diameters can be fixed on the spring grid 5 for testing, which enriches the scope of use.

[0018] In this embodiment, there are two hanging parts 3 which are arranged apart outside the connecting sleeve 2 so as to be stably hung on the spring grid 5 .

[0019] In order to better understand the present technology, the structures of the bottom support portion 1 and the hanging portion 3 will be detailed below.

[0020] like Figure 2 As shown, according to another embodiment of the present utility model, a test tube fixing structure for a full-temperature oscillator spring grid is described, wherein a positioning groove is formed on the top of the bottom support portion 1.

[0021] In this embodiment:

[0022] The bottom support part 1 is an elastic rubber block, and the positioning groove is an arc groove opened on the top of the elastic rubber block. Since the bottom of the test tube is arc-shaped, it is more suitable to place the bottom of the test tube in the positioning groove, which is conducive to more stable positioning of the bottom of the test tube in the positioning groove; and the bottom support part 1 is designed as an elastic rubber block to make soft contact with the bottom of the test tube, thereby improving the safety of the test tube bottom support.

[0023] like Figure 1 As shown, according to another embodiment of the utility model, a test tube fixing structure for a full-temperature oscillator spring grid is described, wherein each of the clamping blocks 4 is connected to the inner wall of the connecting sleeve 2 via a plurality of clamping springs 6 .

[0024] Here, the clamping spring 6 provides a locking force for the clamping block 4 during the clamping process, and can also undergo elastic deformation according to the thickness of the test tube to adjust the distance between the two clamping blocks 4 to meet the purpose of being able to clamp test tubes of different thicknesses.

[0025] like Figure 2 As shown, according to another embodiment of the utility model, a test tube fixing structure for a full-temperature oscillator spring grid, wherein the bottom support part 1 and the connecting sleeve 2 are connected by a connecting piece, and the connecting piece includes an adjusting screw 7 and a guide rod 8; wherein one end of the adjusting screw 7 is rotatably connected to the bottom support part 1 and is also threadedly connected to the connecting sleeve 2; the guide rod 8 is arranged parallel to the adjusting screw 7 and one end of the guide rod 8 is rotatably connected to the bottom support part 1, and the other end of the guide rod 8 is slidably connected to the connecting sleeve 2.

[0026] In this embodiment:

[0027] The bottom support part 1 and the connecting sleeve 2 are connected together to form a whole by adjusting the screw 7 and cooperating with the guide rod 8, and the bottom support part 1 is moved toward or away from the connecting sleeve 2 by rotating the adjusting screw 7 and cooperating with the guidance of the guide rod 8 to change the distance between the bottom support part 1 and the connecting sleeve 2. The appropriate clamping position can be adjusted according to the length of the test tube to make the fixation of the test tube more stable and safe.

[0028] like Figure 2 and Figure 3 As shown, according to another embodiment of the utility model, a test tube fixing structure for a full-temperature oscillator spring grid, wherein the hanging portion 3 includes a hanging card 31 and a limiting unit; wherein one end of the hanging card 31 is fixedly connected to the outer wall of the connecting sleeve 2, and the other end is bent to form a accommodating hole on its inner side, and a hanging opening 32 is left between the two ends of the hanging card 31, and the width of the hanging opening 32 is greater than the diameter of a single spring on the spring grid 5; the limiting unit is movably arranged at the hanging opening 32.

[0029] In this embodiment:

[0030] The shape of the hanging card 31 is similar to a circle, and it can be made of elastic material, which is convenient for hanging the hanging card 31 on the spring grid 5. The width of the hanging opening 32 is designed to be larger than the diameter of a single spring on the spring grid 5, so that a single spring on the spring grid 5 can be inserted into the receiving hole from the hanging opening 32, and then the hanging opening 32 is restricted by the limiting unit to avoid disconnection between the spring grid 5 and the hanging card 31, so that the hanging part 3 can be hung on the spring grid 5 more stably.

[0031] Based on the above scheme:

[0032] A mounting notch 33 is formed at one end of the hanging card 31, and the limiting unit includes a limiting rod 34 and a control structure; wherein, one end of the limiting rod 34 is rotatably arranged in the mounting notch 33 and the other end thereof is rotated inwardly or outwardly of the receiving hole; the control structure is connected to the hanging card 31 and is used to limit or release the limit rod 34 from rotating outwardly of the receiving hole.

[0033] Here, the installation notch 33 is used to provide installation space for the rotating end of the limit rod 34 and ensure that the limit rod 34 will not be restricted in the process of rotating in or out of the receiving hole. When connecting, align the single spring on the spring grid 5 with the hanging port 32, and the spring grid 5 allows the limit rod 34 to rotate into the receiving hole. The process of the hanging card 31 hanging on the spring grid 5 will not be restricted. Then, the limit rod 34 is rotated in the opposite direction to arrange the limit rod 34 along the width direction of the hanging port 32 and the control structure restricts the limit rod 34 from rotating out of the receiving hole, so as to reduce the available width of the hanging port 32. At this time, the single spring on the spring grid 5 cannot be removed from the hanging port 32, and the hanging part 3 is stably hung on the spring grid 5. When it is necessary to remove the hanging part 3 from the spring grid 5, the restriction on the limit rod 34 to rotate out of the accommodating hole is released through the control structure, and the rear limit rod 34 can be rotated out of the accommodating hole. At this time, the available width of the hanging port 32 is increased, and a single spring on the spring grid 5 can be removed from the hanging port 32.

[0034] Furthermore, the control structure includes an obstruction block 35 and a control screw 36; wherein, the obstruction block 35 slides against the rotating end of the limit rod 34 close to the outside of the accommodating hole, and the obstruction block 35 slides in a guide groove 37 opened on the inner wall of the installation notch 33; one end of the control screw 36 is threadedly connected to the obstruction block 35 and the other end thereof is passed through to the outside of the hanging card 31.

[0035] The guide groove 37 guides the sliding of the blocking block 35, so that in the process of rotating the control screw 36, the blocking block 35 moves in the guide groove 37 toward or away from the rotating end of the limit rod 34, so that the blocking block 35 limits the limit rod 34 from rotating out of the receiving hole or releases this restriction, which is easy to operate. Because the rotating end of the limit rod 34 is arranged in an arc shape, the position where the blocking block 35 and the rotating end of the limit rod 34 abut against each other is an adaptive arc surface, so that the blocking block 35 is closely attached to the rotating end of the limit rod 34, and the limiting ability of the limit rod 34 is better.

[0036] When using:

[0037] Turn the adjusting screw 7 according to the length of the test tube to adjust the distance between the bottom support part 1 and the connecting sleeve 2;

[0038] Then hang the hanging card 31 on the spring grid 5;

[0039] Then the bottom end of the test tube is passed through the two clamping blocks 4 and positioned in the positioning groove, and at the same time, the middle part of the tube body of the test tube is clamped by the two clamping blocks 4, thus completing the clamping and fixing of the test tube.

[0040] When the test tube is released from fixation, the test tube can be directly pulled out in a direction away from the clamping block 4 .

[0041] When releasing the connection between the hanging card 31 and the spring grid 5:

[0042] First, the control screw 36 is rotated to move the blocking block 35 in the guide groove 37 away from the limiting rod 34 until it contacts one end of the guide groove 37 and cannot slide further. At this time, the limiting rod 34 is rotated out of the receiving hole, and the spring grid 5 can be removed from the hanging opening 32 to complete the connection between the hanging card 31 and the spring grid 5.

[0043] Then, the limiting rod 34 is rotated into the receiving hole, and the control screw 36 is rotated in the opposite direction to move the blocking block 35 in the guide groove 37 toward the limiting rod 34 and return to the original position. The blocking block 35 again limits the limiting rod 34 from rotating out of the receiving hole for the next connection.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
