Description

Technical Field

[0001] The utility model belongs to the technical field of enzyme labeling plate clamps, in particular to an easy-to-install enzyme labeling plate clamp used in a molecular hybridization furnace. Background Art

[0002] The molecular hybridization oven is an instrument that provides DNA molecular hybridization. In the molecular hybridization oven, an ELISA plate clamp is required to clamp the ELISA plate, which carries the hybridization tube.

[0003] The ELISA plate and the ELISA plate fixture need to be stably clamped. Figure 1 As shown, a bottom plate structure with scrapers on both sides is adopted, and a wavy spring piece is installed on the opposite side of the scraper. The ELISA plate is squeezed in through the opening on the side so that it is clamped between the wavy spring pieces between the scrapers on both sides. This ELISA plate clamping structure has the following disadvantages: (1) The wavy spring piece and the outer scraper are both thin metals, which may easily cause hand cuts when installing and removing the ELISA plate; (2) The installation and removal of the ELISA plate are both pushed or pulled out from the side, which may easily cause the contents in the hybridization tube carried by the ELISA plate to leak; (3) The type and structure of the ELISA plate clamped by the ELISA plate clamp are fixed, and can only be used in a single form, which is not suitable for use in hybridization tubes. It is suitable for clamping various types of ELISA plates with various shapes and sizes. For this purpose, a technical solution for an ELISA plate fixing plate with publication number CN207557274U discloses clamping by arranging an elastic clamp in a side groove. Although it solves the problem of being applicable to ELISA plates with various sizes and shapes, it is necessary to manually stretch the elastic clamping component when installing the ELISA plate, and it is necessary to reach into the molecular hybridization furnace to operate it, and it is relatively inconvenient to directly operate the clamp to clamp it. Therefore, in response to the above problems, the present technical solution proposes an easy-to-install ELISA plate clamp for use in a molecular hybridization furnace. Utility Model Content

[0004] The utility model provides an easy-to-install enzyme labeling plate clamp used in a molecular hybridization furnace. The enzyme labeling plate clamp comprises a bottom plate with a mounting hole and a clamping part movably mounted on the surface of the bottom plate to clamp the enzyme labeling plate. The clamping part selects a matching type according to the specific size and shape of the specific enzyme labeling plate, and is fixed by bolt locking between the positioning hole on the surface and the mounting hole, and can be suitable for the clamping needs of enzyme labeling plates of various forms and sizes. The clamping part adopts a rubber block arranged on the inner side of a limit stop ring to clamp the enzyme labeling plate, and the cross section of the rubber block is an outwardly convex isosceles triangle, so that the enzyme labeling plate can be clamped by directly pressing it down, and can be taken down by lifting it up. Compared with a spring sheet structure, there is no situation of cutting hands, and because the cross section is an outwardly convex isosceles triangle, the internal contents in the hybridization tube carried on the enzyme labeling plate can be prevented from leaking when slowly pressing down and pulling up. In summary, the problems in the background technology are solved.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses an easy-to-install enzyme labeling plate clamp used in a molecular hybridization furnace, comprising a bottom plate and a clamping part movably mounted on the surface of the bottom plate and used for clamping the enzyme labeling plate;

[0007] The clamping part includes a bearing plate with a boss, a limit stop ring arranged on a pair of opposite sides, and a rubber block installed on the inner side wall of the limit stop ring; the bottom shell of the ELISA plate is sleeved on the boss, and a pair of opposite side edges of the bottom shell are located between the boss and the limit stop ring, and the side edges of the ELISA plate are squeezed and clamped by the rubber block on the inner side wall of the limit stop ring.

[0008] Furthermore, a mounting hole is provided on the surface of the bottom plate, a positioning hole is provided on the surface of the boss, and the clamping portion is locked and fixed to the mounting hole by bolts passing through the positioning hole.

[0009] Furthermore, the upper portion of the positioning hole is a large-headed sinking hole, and the lower portion is a through hole for the screw rod of the bolt to pass through.

[0010] Furthermore, the diameter of the large-headed countersunk hole is greater than the diameter of the nut of the bolt, and the depth is greater than the height of the nut of the bolt.

[0011] Furthermore, the cross section of the rubber block is an outwardly convex isosceles triangle, and the side wall of the ELISA plate is clamped by the outwardly convex protrusion.

[0012] Furthermore, the bottom plate and the clamping part are both made of stainless steel.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] (1) The ELISA plate clamp comprises a base plate with mounting holes and a clamping part movably mounted on the surface of the base plate to clamp the ELISA plate. The clamping part is selected to match the specific size and shape of the specific ELISA plate, and is fixed by bolts between the positioning holes on the surface and the mounting holes. It can meet the needs of clamping ELISA plates of various shapes and sizes.

[0015] (2) The clamping part uses a rubber block arranged on the inner side of the limit ring to clamp the ELISA plate, and the cross-section of the rubber block is an isosceles triangle convex outward, so that the ELISA plate can be clamped by pressing it directly, and can be removed by lifting it upwards. Compared with the spring structure, there is no risk of cutting the hand;

[0016] (3) Since the cross section of the rubber block is an outwardly convex isosceles triangle, except for the protruding portion at the outwardly convex position, the rubber block has inclined surfaces at the top and bottom, so that the contents in the hybridization tube carried on the ELISA plate can be prevented from leaking when the rubber block is slowly pressed down and pulled up.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the description of the present invention, it is necessary to understand that the terms "surface", "opposite side", "inner wall", "upper part", "lower part", "cross-section" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0029] An existing ELISA plate fixture is as follows Figure 1 As shown, scrapers are provided on both sides of the bottom plate, and wavy spring pieces are arranged on the inner side walls of the scrapers. The ELISA plate is squeezed in through the opening on the side so as to be clamped between the wavy spring pieces between the scrapers on both sides. The wavy spring pieces and the outer scrapers of this ELISA plate clamping structure are both thin metals, which may easily cause hand cuts when installing and removing the ELISA plate; the ELISA plate is installed and removed by pushing or pulling out from the side, which may easily cause the contents in the hybridization tube carried on the ELISA plate to leak; the ELISA plate clamped by the ELISA plate clamp has a fixed type and structure, and can only use a single form, which is not suitable for the clamping of ELISA plates of multiple forms and sizes; therefore, in view of the above situation, the technical scheme proposes an easy-to-install ELISA plate clamp for use in a molecular hybridization furnace. Specific embodiment 1:

[0031] See also Figure 2 as well as Figure 5-6 As shown, an easy-to-install ELISA plate clamp used in a molecular hybridization oven of the utility model comprises a bottom plate 1 and a clamping part 2 movably mounted on the surface of the bottom plate 1 for clamping the ELISA plate;

[0032] The clamping part 2 includes a supporting plate 25 with a boss 22, a limit stop ring 21 arranged on a pair of opposite sides, and a rubber block 23 installed on the inner wall of the limit stop ring 21; the bottom shell of the ELISA plate is sleeved on the boss 22, and a pair of opposite side edges of the bottom shell are located between the boss 22 and the limit stop ring 21, and the side edges of the ELISA plate are squeezed and clamped by the rubber block 23 on the inner wall of the limit stop ring 21.

[0033] The surface of the bottom plate 1 is provided with a mounting hole 11 , the surface of the boss 22 is provided with a positioning hole 24 , and the clamping portion 2 is locked and fixed to the mounting hole 11 by bolts passing through the positioning hole 24 .

Correspondingly, since the depth of the big-headed sink hole is larger than the nut height of the bolt, it will not cause scratches on the bottom of the ELISA plate.

[0036] The cross section of the rubber block 23 is an outwardly convex isosceles triangle, and the side wall of the ELISA plate is clamped by the outwardly convex protrusion.

[0037] The bottom plate 1 and the clamping part 2 are both made of stainless steel, which has high structural strength, is easy to clean, and is corrosion-resistant and rust-proof.

[0038] In this specific embodiment, the mounting holes on the surface of the corresponding bottom plate 1 are evenly arranged, and two positioning holes 24 are provided on the surface of the corresponding boss 22 of the corresponding clamping part 2, so that fixation can be achieved; during installation, the ELISA plate is pressed down onto the boss 22 along the inner circle of the limit stop ring 21, and a pair of side portions of the ELISA plate are squeezed by the rubber block 23 to achieve stable clamping; Specific embodiment 2:

[0040] The difference between this specific embodiment and specific embodiment 1 is that:
