Description

Technical Field

[0001] The invention relates to the technical field of biological tissue homogenization, and more specifically, to a mounting frame for a biological tissue homogenizer. Background Art

[0002] Existing biological tissue homogenizers are mainly divided into two categories: mechanical homogenizers and ultrasonic homogenizers. Mechanical homogenizers are further divided into handheld homogenizers and desktop homogenizers. In many small units or laboratories, since the demand for processing samples is not large, handheld homogenizers or semi-automatic desktop homogenizers are mainly used.

[0003] Although the purchase cost of this type of homogenizer is low, it mainly relies on manual operation and has high labor requirements. Taking the semi-automatic desktop homogenizer as an example, you first need to place the homogenizer cup containing the biological tissue on the homogenizer and align it with the homogenizer head. Then drive the homogenizer to drive the homogenizer head down so that the homogenizer head falls into the homogenizer cup. Adjust the position of the homogenizer cup again so that the center of the homogenizer cup is aligned with the homogenizer head, and use the support block to fix the homogenizer cup to complete the clamping of the homogenizer cup.

[0004] Since different homogenization cups are of different sizes, the homogenization cup needs to be repeatedly adjusted each time to ensure that the center of the homogenization cup is aligned with the homogenization head before the homogenization cup can be clamped and fixed. This is to prevent the placement of the homogenization cup from deviating, causing the homogenization head to hit the wall of the homogenization cup, or to prevent the homogenization of the biological tissue in the homogenization cup from being uneven. However, the placement of the homogenization cup is more cumbersome, which is not conducive to continuous homogenization and reduces the homogenization efficiency.

[0005] Therefore, in order to solve the above technical problems, the present invention provides a mounting bracket for a biological tissue homogenizer. Summary of the invention

[0006] In view of the deficiencies in the prior art, the object of the present invention is to provide a mounting bracket for a biological tissue homogenizer.

[0007] To achieve the above object, the present invention provides the following technical solution: a mounting frame for a biological tissue homogenizer, comprising:

[0008] An adjusting rod installed on the homogenizer, wherein a clamping mechanism is installed on the adjusting rod, and the clamping mechanism is arranged just below the homogenizing head;

[0009] The clamping mechanism includes a torsion ring, a limit ring A, a clamping ring and a limit ring B, and the torsion ring, limit ring A, clamping ring and limit ring B are arranged in sequence, the clamping ring is composed of a plurality of clamping blocks, and in order to be suitable for a round-mouthed homogenizing cup, a ring shape can be formed, and a sliding rod is installed on a side of each clamping block close to the limit ring A and the limit ring B, and the limit ring A is provided with a corresponding number of straight grooves A at positions corresponding to the plurality of sliding rods, and the limit ring B is provided with a corresponding number of straight grooves B at positions corresponding to the plurality of sliding rods, and the plurality of sliding rods are slidably connected in the corresponding straight grooves A or straight grooves B, and the straight grooves A and straight grooves B are both used to limit the sliding rods;

[0010] The torsion ring is rotatably connected to the limit ring A, and a corresponding number of arc grooves are opened at the position of the torsion ring corresponding to the straight groove A. Multiple sliding rods close to one side of the limit ring A all penetrate the straight groove A and extend into the arc groove, and are slidably connected in the arc groove. Each of the arc grooves is in a shape that extends obliquely from the inner edge surface of the torsion ring toward the outer edge surface;

[0011] The limit ring A is provided with a plurality of slide grooves, and a corresponding number of sliders are installed at positions corresponding to the plurality of slide grooves on the torsion ring, each of the sliders is slidably installed in the corresponding slide groove, and each slider is connected to the corresponding slide groove via a spring;

[0012] Each of the clamping blocks is equipped with an interference block.

[0013] Furthermore, each of the resistance blocks is connected with an elastic band.

[0014] Furthermore, each of the sliding bars is square, and the width of each sliding bar is the same as the width of the sliding groove.

[0015] Furthermore, the surface of the abutment block is wrapped with a buffer layer.

[0016] Furthermore, the limiting ring A, the clamping ring and the limiting ring B are all wrapped with a shell.

[0017] Furthermore, the adjusting rod includes a sliding rod A and a sliding rod B, the sliding rod A and the sliding rod B are slidably connected, and a fixing mechanism for limiting is provided between the sliding rod A and the sliding rod B.

Therefore, when the homogenizer cup is clamped and fixed, the resistance block will also push the homogenizer cup toward the center, so that the center position of the homogenizer cup can always be aligned with the homogenizer head, thereby facilitating the fixation of the homogenizer cup, simplifying the clamping steps, and improving the clamping efficiency during continuous clamping.

[0030] like Figure 1-8 As shown, the present invention provides a mounting bracket for a biological tissue homogenizer, comprising an adjusting rod 3 mounted on a homogenizer 1 , a clamping mechanism 4 mounted on the adjusting rod 3 , and the clamping mechanism 4 is arranged just below a homogenizing head 2 .

[0031] The clamping mechanism 4 includes a torsion ring 41, a limiting ring A42, a clamping ring 44 and a limiting ring B43, and the torsion ring 41, the limiting ring A42, the clamping ring 44 and the limiting ring B43 are arranged in sequence.

[0032] The limiting ring A42, the clamping ring 44 and the limiting ring B43 are all wrapped with a shell 9, which can protect the limiting ring A42, the clamping ring 44 and the limiting ring B43 inside, and can also provide supporting force.

[0033] The clamping ring 44 is composed of a plurality of clamping blocks 441. Since the mouth of the homogenizing cup is generally round, the plurality of clamping blocks 441 can form a ring. A sliding rod 442 is installed on one side of each clamping block 441 close to the limiting ring A42 and the limiting ring B43. The limiting ring A42 is provided with a corresponding number of straight grooves A421 at positions corresponding to the plurality of sliding rods 442. The limiting ring B43 is provided with a corresponding number of straight grooves B431 at positions corresponding to the plurality of sliding rods 442. The plurality of sliding rods 442 are slidably connected in the corresponding straight grooves A421 or B431.

[0034] Each slide bar 442 is square, and the width of each slide bar 442 is the same as the width of the slide groove 5, so as to prevent the slide bar 442 from rolling when sliding in the straight groove A421 or the straight groove B431.

[0035] The straight groove A421 and the straight groove B431 both limit the slide bar 442. The slide bars 442 are arranged at both ends of the clamping block 441. The straight groove A421 and the straight groove B431 limit the slide bar 442, which can increase the stability of the clamping block 441 when moving.

[0036] The torsion ring 41 is rotatably connected to the limit ring A42, and a corresponding number of arc grooves 411 are opened at positions of the torsion ring 41 corresponding to the straight grooves A421. A plurality of sliding rods 442 close to one side of the limit ring A42 all penetrate the straight grooves A421 and extend into the arc grooves 411, and are slidably connected in the arc grooves 411. Each arc groove 411 is in a shape that extends obliquely from the inner edge surface of the torsion ring 41 toward the outer edge surface.

[0037] A plurality of slide grooves 5 are provided on the limiting ring A42, and a corresponding number of sliders 412 are installed at positions corresponding to the plurality of slide grooves 5 on the torsion ring 41. Each slider 412 is slidably installed in the corresponding slide groove 5, and each slider 412 is connected to the corresponding slide groove 5 via a spring 6.

[0038] The slider 412 can be designed to be engaged with the slide groove 5, thereby improving the stability of the torsion ring 41 when rotating on the surface of the limit ring A42.

[0039] A resistance block 8 is mounted on each clamping block 441 .

[0040] The surface of the abutment block 8 is wrapped with a buffer layer, which can protect the homogenization cup when the abutment block 8 contacts the homogenization cup, and prevents the abutment block 8 from rebounding with great force, thereby damaging the homogenization cup.

[0041] In actual use, refer to Figure 4 , rotate the torsion ring 41, so that the slide bar 442 extending into the arc groove 411 slides with the rotation of the torsion ring 41. Since the arc groove 411 is a shape that extends from the inner edge surface of the torsion ring 41 to the outer edge surface, it can be understood that when on the inner edge surface of the arc groove 411, several slide bars 442 are close to each other, and as the torsion ring 41 rotates, driven by the arc groove 411, several slide bars 442 move away from each other. At the same time, under the limitation of the limit ring A42 and the limit ring B43, when the slide bar 442 is driven by the torsion ring 41 to make a circular expansion motion around, it will be limited by the straight groove A421 and the straight groove B431, so that the movement trajectory of the slide bar 442 is more stable.

[0042] It is worth noting that the shape of the straight groove A421 can be a shape extending vertically outward from the inner edge surface of the limiting ring A42, and the shape of the straight groove B431 can be the same as the straight groove A421, which mainly plays a role in providing stable support for the sliding rod 442.

[0043] When the torsion ring 41 rotates, the slide bar 442 drives the clamping block 441 to expand outward in a circular manner, so that the abutment blocks 8 are dispersed at equal intervals around the original center point.

[0044] Then the cup mouth or cup neck of the homogenization cup is placed between the abutment blocks 8 accordingly.

[0045] It should be noted that the slider 412 on the torsion ring 41 is slidably connected in the slide groove 5 provided on the limit ring A42, and the two are connected by a spring 6. When the torsion ring 41 rotates, the spring 6 will be stretched.

[0046] It is worth noting that when the spring 6 is in a stationary and unstressed state, the slide bar 442 is located at one end of the arc groove 411 close to the inner edge of the torsion ring 41. At this time, driven by the slide bar 442 and the clamping block 441, the distance between the abutment blocks 8 is the shortest.

[0047] After placing the cup mouth or cup neck of the homogenization cup between the resistance blocks 8, release the hand that rotates the torsion ring 41. Since the rotation of the torsion ring 41 stretches the spring 6, after releasing the torsion ring 41, the torsion ring 41 rotates to restore the deformation under the elastic force of the spring 6. Since the cup mouth or cup neck of the homogenization cup supports the resistance block 8, the spring 6 cannot drive the torsion ring 41 to completely restore. At this time, the spring 6 gives the torsion ring 41 a restoring pulling force, and the torsion ring 41 drives the clamping block 441 to contract through the sliding rod 442, thereby driving the resistance block 8 to tighten toward the center, thereby clamping the homogenization cup.

[0048] The homogenizer cup can be quickly clamped by the clamping mechanism 4, and driven by the torsion ring 41, the resistance block 8 always moves outward from a center of a circle at equal intervals. Therefore, when the homogenizer cup is clamped and fixed, the resistance block 8 will also push the homogenizer cup toward the center, so that the center position of the homogenizer cup can always be aligned with the homogenizer head 2, thereby facilitating the fixation of the homogenizer cup, simplifying the clamping steps, and improving the clamping efficiency during continuous clamping.

[0049] When the homogenization is completed, the torsion ring 41 is rotated again. According to the above principle, the abutment block 8 moves away from the homogenization cup and loses its grip on the homogenization cup, so the homogenization cup can be removed.

[0050] Because the resistance block 8 moves away from the center at equal intervals under the drive of the clamping block 441 and the slide rod 442, no matter the size of the homogenizing cup, the center position of the homogenizing cup of different sizes can always be aligned with the homogenizing head 2, which is convenient for clamping the homogenizing cup and improves the clamping efficiency.

[0051] In order to improve the clamping of the homogenizer cup, an elastic band 7 is connected between each resistance block 8, and the elastic band 7 can be stretched. By rotating the torsion ring 41, the sliding rod 442 and the clamping block 441 drive the resistance block 8 to expand. When the resistance block 8 expands, the elastic band 7 will be stretched. After loosening the torsion ring 41, in addition to the tension provided by the original spring 6 to the resistance block 8, the elastic band 7 will also provide tension to the resistance block 8 when it recovers its deformation, driving the resistance block 8 to contract and clamp the internal homogenizer cup.

[0052] Similarly, after rotating the torsion ring 41, the resistance block 8 is stretched open to drive the elastic band 7 to stretch, so that the homogenizer cup can be taken out from the resistance block 8, and then the torsion ring 41 is loosened. When the spring 6 originally gives the torsion ring 41 a restoring pulling force, the elastic band 7 can additionally give the torsion ring 41 a restoring pulling force, and at the same time, when clamping the homogenizer cup, it can give the homogenizer cup a greater pulling force, thereby providing more stable support for the homogenizer cup.

[0053] The surface of the abutment block 8 is wrapped with a buffer layer, which can not only provide buffering when the abutment block 8 clamps the homogenization cup, but also prevent the abutment block 8 from hitting the homogenization cup and causing damage to the homogenization cup. In addition, since the mouth of the homogenization cup is generally designed with a protruding arc-shaped outer edge for easy pouring, the buffer layer can adapt to the shape of the homogenization cup and fit to the mouth and wall of the homogenization cup, thereby providing greater friction and making the clamping of the homogenization cup more stable.

[0054] It is worth noting that the adjustment rod 3 includes a sliding rod A31 and a sliding rod B32, and the sliding rod A31 and the sliding rod B32 are slidably connected, and a fixing mechanism for limiting is arranged between the sliding rod A31 and the sliding rod B32. The structure of the sliding rod A31 and the sliding rod B32 is similar to the lifting mechanism of the lifting seat. By sliding the connecting rod B, the connecting rod B is retracted into the connecting rod A, so that the height of the clamping mechanism 4 can be adjusted, and the fixing mechanism can fix the position of the connecting rod B, so that the clamping mechanism 4 can be maintained at this height for homogenization. The principle of the fixing mechanism adopts the existing technology, which is similar to the method of adjusting the lifting seat. Through a wrench, the fixing of the connecting rod B is released, so that the connecting rod B can be driven to move in the connecting rod A, driving the clamping mechanism 4 to be adjusted. The fixing mechanism can also be other mechanisms. As the existing technology, it will not be repeated here.

[0055] By sliding between the connecting rod B and the connecting rod A, it is convenient to adjust the clamping mechanism 4. Since the homogenizer head 2 needs to extend to the bottom of the homogenizer cup for homogenization, when clamping the homogenizer cup, it is necessary to drive the clamping mechanism 4 to move to the bottom of the homogenizer head 2 through the connecting rod B, and then it is convenient to clamp the homogenizer cup. After clamping, the clamping mechanism 4 is driven to rise through the homogenizer cup until the homogenizer head 2 penetrates into the appropriate position at the bottom of the homogenizer cup, and then the fixing mechanism fixes the connecting rod B, and the homogenization operation can be performed at this time.

[0056] The invention can solve the problem that the traditional method requires manual operation to move the homogenizer head 2 or the homogenizer 1 up and down, thereby improving the fixing efficiency of the homogenizer cup.
