Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of test tube brackets, in particular to a test tube bracket. Background Art
[0002] Test tubes are a common laboratory tool, usually made of glass or plastic, and are slender cylindrical. They are used to hold and mix liquid samples, chemical reagents, or perform different experimental operations. Test tubes vary in size and shape to suit different experimental needs. Generally speaking, test tubes usually have graduated capacity lines to facilitate accurate liquid measurement. Test tubes can be divided into ordinary test tubes, supported test tubes, centrifugal test tubes, etc. Test tube racks are the most basic experimental instruments in chemical laboratories used to place and dry test tubes. The test tube racks are equipped with a corresponding number of small holes to place test tubes upright for standby use or to continue observing the reaction.
[0003] The existing medical test tube rack has one side for placing the test tube upright and the other side for placing the test tube upside down for filtering water. The test tube rack is usually fixed, and the experimental test tubes are usually of various models for ease of use, resulting in differences in the lengths of test tubes of different models, and the efficiency of their use on the test tube rack is also different. A taller test tube may tilt or even fall due to the lower bearing position of the test tube rack and the gap between the test tube rack and the test tube rack, while a shorter test tube may not be able to touch the bottom of the test tube rack, resulting in an unstable center of gravity, thereby being affected during the experiment.
[0004] Therefore, it is necessary to provide a new test tube support to solve the above technical problems. Utility Model Content
[0005] In order to solve the above technical problems, the utility model provides a test tube support.
[0006] The test tube support provided by the utility model comprises a fixed partition and a plurality of adjustment components, the top ends of the fixed partition are divided into a placement layer and a water filter layer, a plurality of the adjustment components are arranged at equal intervals on the side wall of the placement layer, a plurality of semicircular grooves for supporting test tubes are arranged at equal intervals on the top of the placement layer, a plurality of water filter supports are fixedly connected at equal distances on the top of the water filter layer, and a plurality of stabilizing pads are respectively arranged on the tops of the water filter supports;
[0007] The adjustment component includes a frame-type bracket, a limit rack and a limit frame. The frame-type bracket and the limit rack are horizontally arranged on the side walls of the placement layer along the vertical direction respectively. The inner walls of the limit frame are respectively provided with two movable rollers for fixing the test tubes. The outer walls of the limit frame are respectively provided with a sliding bracket and a limit bracket. The outer wall of the sliding bracket is movably connected to the inner wall of the frame-type bracket. The inner wall of the limit bracket is provided with a limit ratchet. The limit ratchet is movably connected to the inner wall of the limit rack, and an elastic member is provided between the limit frame and the limit ratchet.
[0008] Furthermore, an end of the limiting frame away from the limiting bracket is fixedly connected with an adjustment handle.
[0009] Furthermore, the elastic member is a spring, and two ends of the spring are respectively fixedly connected to the outer side wall of the limiting frame and the side wall of the limiting ratchet.
[0010] Furthermore, a rotating handle is provided on the outer side wall of one end of the limiting ratchet along the extending limiting bracket and the center of one end of the limiting ratchet is outside the movable through hole opened along the extending limiting bracket, and the rotating handle is fixedly connected to the limiting ratchet.
[0011] Furthermore, a limiting groove is formed through the inner side wall of the frame-shaped bracket in a vertical direction, and the outer side wall of the sliding bracket is movably connected to the inner wall of the limiting groove of the frame-shaped bracket.
[0012] Furthermore, both ends of the top of the limiting bracket are fixedly connected with a blocking bracket, and the bottom of the blocking bracket is in contact with the limiting ratchet.
[0013] Compared with the related art, the test tube support provided by the utility model has the following beneficial effects:
[0014] 1. The utility model is provided with a frame-type bracket, a limit rack and a limit frame. The two movable rollers are placed between the two movable rollers until the bottom is fitted with the top of the semicircular groove. The two movable rollers slide on the surface of the test tube, thereby reducing contact friction and improving the service life of the test tube. The limit frame is adjusted along with the height of the test tube. The limit frame is raised, and the sliding bracket slides in the vertical direction of the inner wall of the frame-type bracket. During the rising process, the limit ratchet squeezes the top of the limit rack to contract the elastic member, and the limit ratchet fits at the top of the limit rack to expand the pressure elastic member. When the limit ratchet is adjusted to a suitable position, the expansion force of the elastic member fits to the root of the limit rack, thereby fixing the two movable rollers, better fixing the test tube, and reducing the tipping caused by insufficient center of gravity.
[0015] 2. The utility model provides multiple water filter brackets and multiple stabilizing pads. The multiple water filter brackets can filter water from multiple test tubes at the same time. By providing stabilizing pads, the contact area inside the test tubes is increased, making them more stable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.
[0023] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 , Figure 1 A schematic diagram of the overall structure of the test tube support provided by the utility model; Figure 2 A schematic diagram of the structure of the test tube support provided by the utility model; Figure 3 A schematic cross-sectional view of the adjustment assembly provided by the utility model; Figure 4 A schematic diagram of the structure of the adjustment assembly provided by the utility model; Figure 5 This is a schematic structural diagram of the position-limiting ratchet and the position-limiting rack provided by the utility model.
[0024] In the specific implementation process, Figures 1 to 5 As shown, the test tube support includes a fixed partition 1 and a plurality of adjustment components. The top ends of the fixed partition 1 are divided into a placement layer 2 and a water filter layer 4. The plurality of adjustment components are arranged at equal intervals on the side wall of the placement layer 2. The top of the placement layer 2 is provided with a plurality of semicircular grooves 3 for supporting the test tubes at equal intervals. The top of the water filter layer 4 is fixedly connected with a plurality of water filter supports 5 at equal distances. The tops of the plurality of water filter supports 5 are respectively provided with stabilizing pads 6.
[0025] The adjusting assembly comprises a frame-type bracket 7, a limiting rack 8 and a limiting frame 9. The frame-type bracket 7 and the limiting rack 8 are respectively arranged horizontally on the side walls of the placement layer 2 in the vertical direction. The inner walls of the limiting frame 9 are respectively provided with two movable rollers 11 for fixing the test tubes. The outer walls of the limiting frame 9 are respectively provided with a sliding bracket 12 and a limiting bracket 13. The outer wall of the sliding bracket 12 is movably connected to the inner wall of the frame-type bracket 7. The inner wall of the limiting bracket 13 is provided with a limiting ratchet 15. The limiting ratchet 15 is movably connected to the inner wall of the limiting rack 8, and an elastic member is arranged between the limiting frame 9 and the limiting ratchet 15. The elastic member is a spring 17. Both ends of the spring 17 are respectively fixedly connected to the outer wall of the limiting frame 9 and the side wall of the limiting ratchet 15. The end of the limiting frame 9 away from the limiting bracket 13 is fixedly connected with an adjusting handle 10. By setting the adjusting handle 10, the user can more conveniently adjust the limiting frame 9 through the adjusting handle 10. The center of one end of the positioning ratchet 15 is outside the movable through hole opened along the extended limit bracket 13, and the limiting ratchet 15 is provided with a rotating handle 16 along the outer side wall of one end of the extended limit bracket 13. The rotating handle 16 is fixedly connected to the limiting ratchet 15. By adjusting the rotating handle 16, it is rotated in the vertical direction, and the limiting ratchet 15 at the bottom is retracted into the inside of the limiting bracket 13, which is convenient for adjusting the subsequent fixing of test tubes of different heights. The inner side wall of the frame bracket 7 is penetrated by a limiting groove in the vertical direction, and the outer side wall of the sliding bracket 12 is movably connected to the inner wall of the limiting groove of the frame bracket 7. Through the sliding of the sliding bracket 12, it is always kept sliding in the vertical direction. The two ends of the top of the limiting bracket 13 are fixedly connected with a resisting bracket 14, and the bottom of the resisting bracket 14 is in contact with the limiting ratchet 15. The resisting bracket 14 will limit the specified angle when the limiting ratchet 15 is rotated, so that it will not be stretched and expanded by the expansion force of the elastic member.
[0026] The working principle of the utility model is as follows: when the utility model is implemented, the test tube is inverted onto the water filter bracket 5 through the multiple water filter brackets 5 of the water filter layer 4, so that the water inside the test tube flows out to the bottom, and the water of multiple test tubes is filtered at the same time. By setting the stabilizing pad 6, the contact area inside the test tube is enlarged to make it more stable. When the test tube needs to be placed, it is placed between the two movable rollers 11 until the bottom is attached to the top of the semicircular groove 3. The two movable rollers 11 slide on the surface of the test tube to reduce contact friction, thereby extending the service life of the test tube. The limit frame 9 is adjusted with the height of the test tube. By raising the limit frame 9, the sliding bracket 12 slides in the vertical direction of the inner wall of the frame bracket 7, and in the rising process, the limit ratchet 15 squeezes the top of the teeth of the limit rack 8 to shrink the elastic member, and the limit ratchet 15 fits at the top of the teeth of the limit rack 8 to expand the pressure elastic member, so that when it is adjusted to the appropriate position, the limit ratchet 15 fits to the root of the limit rack 8 due to the expansion force of the elastic member, so that the two movable rollers are fixed, and the test tube is better fixed to reduce the tipping caused by insufficient center of gravity.
