DETAILED DESCRIPTION

[0022] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0023] The following is combined with Figure 1-Figure 5 This embodiment is described in further detail.

[0024] like Figure 1-2 As shown, a simple test tube brush in this embodiment includes a retractable brush rod 100 and bristles 110 arranged at one end of the brush rod 100, and a detachable hanging hole assembly 120 is provided at the other end of the brush rod 100. The hanging hole assembly 120 includes a frame 121, and a slidable support plate 122 is provided in the frame 121. A hanging hole is formed between the support plate 122 and the upper end wall of the frame 121, and a driving member for driving the support plate 122 to slide to adjust the size of the hanging hole is provided at the lower end wall of the frame 121.

[0025] In this embodiment, the brush rod 100 is in the shape of a straight rod, and the bristles 110 are arranged at one end of the brush rod 100. Thus, the operator holds the brush rod 100 to drive the bristles 110 to extend into the test tube, and by rotating and pulling the brush rod 100, the bristles 110 can be driven to brush and clean the inner wall of the test tube, thereby completing the cleaning of the test tube.

[0026] In this embodiment, the hanging hole assembly 120 is provided so that the test tube brush can be hung when not in use, for example, hung on an existing test tube rack. When it is actually used, the frame 121 and the support plate 122 are provided so that the support plate 122 can be lifted and slid in the frame 121, so that the distance between the support plate 122 and the upper end wall of the frame 121 can be adjusted, and then the size of the hanging hole formed therebetween can be adjusted, so that the test tube brush can be hung on test tube racks of different models through the hanging hole, that is, the applicability of the test tube brush is improved;

[0027] It should be noted that a hook for hanging a test tube brush is usually provided on the test tube rack, and the hook sizes on different types of test tube racks are different. Therefore, the test tube brush is adjusted by the size of the hanging hole so that it can be hung on test tube racks of different types.

[0028] Among them, by setting the driving member, it can drive the support plate 122 to rise and fall and slide in the frame 121, so as to adjust the size of the hanging hole, and the adjustment is simple and convenient;

[0029] In this embodiment, the length of the brush rod 100 is adjusted by the telescopic setting of the brush rod 100, so that the test tube brush can brush and clean test tubes of different lengths, thereby preferably improving the applicability of the test tube brush.

[0030] Combination Figure 3As shown, in this embodiment, a first threaded rod 300 is provided on the lower end wall of the frame 121, and a first threaded hole 311 for the first threaded rod 300 to threadably extend therein is provided at the other end of the brush rod 100.

[0031] In this embodiment, the detachable setting of the hanging hole assembly 120 on the brush rod 100 is preferably achieved through the cooperation between the first threaded rod 300 and the first threaded hole 311 .

[0032] Combination Figure 4-5 As shown, in this embodiment, through holes 501 are provided at both ends of the support plate 122 for the opposite side walls of the frame body 121 to pass through, and a second threaded rod 510 is provided on the support plate 122; the driving member includes a swivel 320 rotatably provided on the lower end wall of the frame body 121, a mounting hole is provided in the first threaded rod 300, and the second threaded rod 510 is threaded through the swivel 320 and extends into the mounting hole.

[0033] In this embodiment, the side walls opposite to the frame 121 are concavely arranged along the extension direction thereof, that is, the cross-sectional dimensions of the side walls opposite to the frame 121 are reduced, so that the side walls can slide through the through holes 501 on the support plate 122, thereby ensuring that the dimensions of the support plate 122 match those of the frame 121, and preventing the support plate 122 from protruding out of the frame 121, thereby affecting the actual use of the hanging hole assembly 120;

[0034] Among them, through the arrangement of the swivel 320, the mounting hole and the second threaded rod 510, in actual use, the support plate 122 is restricted and cannot rotate by utilizing the through hole 501 arranged through the relative side wall of the frame 121, even if the second threaded rod 510 thereon is restricted and cannot rotate circumferentially. At this time, by utilizing the threaded cooperation between the swivel 320 and the second threaded rod 510, the forward and reverse rotation of the swivel 320 can drive the second threaded rod 510 to extend and retract in the mounting hole, thereby driving the support plate 122 to rise and fall and slide in the frame 121.

[0035] In this embodiment, an installation groove 401 for installing the swivel 320 is provided on one end wall of the frame 121, and a limiting slide groove 402 is provided on the side wall of the installation groove 401 along its circumference. A slidable installation block 520 is provided in the limiting slide groove 402, and the installation block 520 is fixedly installed on the outer wall of the swivel 320 by screws 521.

[0036] In this embodiment, the mounting groove 401 is coaxially arranged with the mounting hole, and the two are connected to each other. In actual use, the diameter of the mounting groove 401 is larger than the diameter of the mounting hole, so that the swivel 320 can be rotatably installed therein;

[0037] The limiting slide groove 402, the mounting block 520 and the screw 521 are arranged so that the limiting slide groove 402 is connected to the outer wall of the frame 121, thereby enabling the mounting block 520 to slide into the limiting slide groove 402 and be mounted on the outer wall of the rotating ring 320 by means of the screw 521. Since the mounting block 520 can slide along the circumferential direction in the limiting slide groove 402, when the mounting block 520 is mounted outside the rotating ring 320, the rotating installation of the rotating ring 320 in the mounting groove 401 can be preferably realized;

[0038] Among them, one end of the swivel 320 extends out of the installation groove 401, and its protruding end extends outward to form a circular ring portion 531, so that the operator can better drive the swivel 320 to rotate in the installation groove 401 by rotating the circular ring portion 531, so that the lifting and lowering operation of the support plate 122 is simple and convenient.

[0039] Combination Figure 1-3 As shown, in this embodiment, the brush rod 100 includes a top rod 102 and a bottom rod 101, the bristles 110 are arranged at one end of the bottom rod 101, the hanging hole assembly 120 is arranged on the top rod 102, a second threaded hole 201 is arranged at the other end of the bottom rod 101, and one end of the top rod 102 is provided with a third threaded rod 211 that is threaded and extends into the second threaded hole 201.

[0040] Through the structure of this embodiment, when it is necessary to adjust the length of the brush rod 100 in actual use, the length of the brush rod 100 can be adjusted by making the top rod 102 and the bottom rod 101 rotate relative to each other and adjusting the depth of the third threaded rod 211 extending into the second threaded hole 201. The adjustment operation is simple and convenient.

[0041] In this embodiment, the bristles 110 are evenly arranged on a sleeve 130 , and the sleeve 130 is threadedly connected to the bottom rod 101 .

[0042] In this embodiment, the sleeve 130 is threadedly connected to the bottom rod 101, so that when the bristles 110 are damaged, the bristles 110 can be replaced better, that is, the brush rod 100 can be reused to improve the applicability of the test tube brush;

[0043] It should be noted that the friction resistance of the threaded connection between the sleeve 130 and the bottom rod 101 is relatively large, that is, when the test tube brush is used to brush the test tube, the rotation of the bristles 110 will not affect the threaded installation of the sleeve 130 on the bottom rod 101.

[0044] Working principle: According to actual needs, the operator can drive the rotating ring 320 to rotate by rotating the annular portion 531, and then can adjust the lifting and lowering of the support plate 122 in the frame 121, so as to adjust the hanging hole to a suitable size, and the test tube brush can be hung on different test tube racks; when the length of the test tube brush needs to be adjusted to adapt to the test tube, the brush rod 100 can be adjusted to a suitable length by making the top rod 102 and the bottom rod 101 rotate relative to each other, and the operation is simple and convenient.

[0045] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
