Description

Technical Field

[0001] The invention relates to the technical field of electrophoresis equipment, in particular to an electrophoresis truss hanger. Background Art

[0002] Electrophoresis refers to the phenomenon that charged particles move toward electrodes with opposite electrical properties under the action of an electric field. The technology that uses the different moving speeds of charged particles in an electric field to achieve separation is called electrophoresis technology. Electrophoresis has been increasingly widely used in various fields such as analytical chemistry, biochemistry, clinical chemistry, toxicology, pharmacology, immunology, microbiology, and food chemistry. When the existing escalator truss is undergoing the electrophoresis process, since the bottom of the escalator truss is sealed, a short buoyancy will be generated when the truss enters the electrophoresis tank and contacts the liquid. In addition, the truss is generally hung on the truss hanger, so the truss will be unhooked when it contacts the liquid, causing an accident. Therefore, a device is needed to improve the above problem. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1-4 , an embodiment of the present invention: an electrophoresis truss hanger, comprising a support and hanging device 2, a limited connection device 3 is fixedly installed on the top of the support and hanging device 2, a positioning and extrusion device 1 is slidably inserted inside the side end of the support and hanging device 2, and the positioning and extrusion device 1 comprises a limited sealing plate 4, a movable plug rod 5, a first anti-slip clamping plate 6, a movable contact plate 7, a positioning plate 8 and a rotating screw 9, the rotating screw 9 is rotatably connected to the side end center of the positioning plate 8, the movable contact plate 7 is fixedly connected to the bottom end of the positioning plate 8, the first anti-slip clamping plate 6 is fixedly connected to the side of the movable contact plate 7 away from the rotating screw 9, and the movable The insertion rod 5 is symmetrically fixedly connected to the top end of the movable contact plate 7, the limiting sealing plate 4 is fixedly connected to the end of the movable insertion rod 5 away from the positioning plate 8, the supporting hanging device 2 includes a second anti-slip clamping plate 10, a sliding groove 11, a supporting hook plate 12, a threaded hole 13 and a supporting frame 14, the sliding groove 11 is opened at both ends of the inside of the supporting frame 14, the threaded hole 13 is opened at the side end center of the supporting frame 14, the supporting hook plate 12 is fixedly connected to the bottom end of the supporting frame 14, the second anti-slip clamping plate 10 is fixedly connected to the bottom of the side end of the supporting frame 14, and the second anti-slip clamping plate 10 is located above the supporting hook plate 12.

[0020] The limiting connection device 3 includes a positioning card plate 15, a mounting threaded rod 16, a nut 17 and an A-type connecting frame 18. The mounting threaded rod 16 is fixedly connected to the four corners of the bottom end of the positioning card plate 15, and the mounting threaded rod 16 is located inside the top end of the A-type connecting frame 18. The nut 17 is threadedly sleeved on the mounting threaded rod 16. By changing the distance between the positioning card plate 15 and the A-type connecting frame 18, and then screwing the nut 17 to the extreme position, the A-type connecting frame 18 and the positioning card plate 15 can be fixed on a crane hoist with different thicknesses.

[0021] The A-type connecting frame 18 is fixedly connected to the top of the supporting frame body 14 to support the supporting frame body 14 for clamping.

[0022] A flow groove is provided in the center of the support frame 14 to facilitate the electrophoresis liquid to pass through the support frame 14 quickly.

[0023] The movable plug rod 5 is slidably inserted into the sliding groove 11, and the rotating screw rod 9 is threadedly inserted into the threaded hole 13, so as to keep the movable contact plate 7 moving along a straight line and avoid the skewing phenomenon when fixing the escalator truss.

[0024] When the rotating screw rod 9 is screwed to the limit position, the first anti-slip clamping plate 6 contacts the second anti-slip clamping plate 10, and the escalator truss with different thicknesses can be fixed between the first anti-slip clamping plate 6 and the second anti-slip clamping plate 10.

[0025] Working principle: During use, first hang the positioning card plate 15 on the sling of an external crane until the driving installation threaded rod 16 penetrates through the installation hole at the top of the A-type connecting frame 18. At this time, the nut 17 can be screwed to the limit position on the installation threaded rod 16, so that the positioning card plate 15 and the A-type connecting frame 18 are fastened to the crane sling, completing the overall installation work of this device. At this time, then place the top of the escalator truss to be electrophoresed externally into the inside of the support hook plate 12. Since the inside of the support hook plate 12 is arranged in a concave state, it is convenient to temporarily place the escalator truss inside the support hook plate 12. At the same time, it can also prevent the escalator truss from falling off inside the support hook plate 12. At this time, by rotating the screw rod 9 threadedly penetrating through the threaded hole 13 and rotatably connected to the side end of the positioning plate 8, the screw rod 9 can be screwed to drive the positioning plate 8 to move inward. At this time, since the moving contact plate 7 is fixedly connected to the bottom end of the positioning plate 8, when the positioning plate 8 moves, it can drive the moving contact plate 7 to move inward at the same time. When the moving contact plate 7 contacts the escalator truss, the first anti-slip clamping plate 6 will contact the escalator truss in advance, so as to prevent the moving contact plate 7 from sliding when contacting the escalator truss. At the same time, when the moving contact plate 7 moves, by sliding the moving insertion rod 5 into the inside of the sliding groove 11, it can ensure that the moving contact plate 7 moves inward along a straight line and avoid the moving contact plate 7 from tilting when moving. As the user continuously screws the rotating screw rod 9 inward, the moving contact plate 7 can be pushed to push the escalator truss to be fastened to the second anti-slip clamping plate 10, completing the positioning and clamping work of the escalator truss. When this device is in use, the limit sealing plate 4 is fixedly connected to one end of the moving insertion rod 5, so as to prevent the moving contact plate 7 from falling off when moving outward. At the same time, by controlling the distance of screwing the rotating screw rod 9 inward, escalator trusses of different specifications can be clamped. The user can loosen the nut 17 to release and expand the distance between the positioning card plate 15 and the A-type connecting frame 18, so as to facilitate fixing the A-type connecting frame 18 on crane slings of different thicknesses.

[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
