Technical Field

[0001] The utility model relates to the technical field of samplers, in particular to a viscous sample sampler structure. Background Art

[0002] Since viscous samples have high concentrations and large viscosity and are difficult to absorb, thicker glass tubes are generally used to transfer the samples to containers for testing. Due to the high viscosity of viscous samples, they will adhere to the inner wall of the sampler, making it inconvenient to clean and remove the viscous samples on the inner wall of the sampler, increasing the difficulty of the work. Therefore, a viscous sample sampler structure is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0031] See also Figures 1 to 5 In this embodiment, a viscous sample sampler structure includes a sampling cylinder 1, a movable rod 2 and a chassis 3. The interior of the sampling cylinder 1 is movably connected to the movable rod 2. The chassis 3 is located below the sampling cylinder 1 and is fixedly connected to the bottom of the movable rod 2. The top of the movable rod 2 is fixedly connected to a turntable. The axis of the turntable and the axis of the movable rod 2 are located on the same straight line, and the movable rod 2 can be easily driven to rotate by the turntable.

[0032] The sampling tube 1 is composed of an upper tube 101 and a lower tube 102. The surface of the upper tube 101 is provided with a fixing assembly 4, which is used to fix the upper tube 101 and the lower tube 102. The fixing assembly 4 includes a connecting seat 401, a connecting rod 402 and a clamping block 403. Among them, there are two connecting seats 401, which are evenly distributed on the left and right sides of the upper tube 101. The connecting rod 402 is located on the inner side of the connecting seat 401 and is hinged to the connecting seat 401. The connecting rod 402 and the connecting seat 401 are hinged through a rotating shaft. The outer sleeve of the rotating shaft is provided with a torsion spring. One end of the torsion spring abuts against the connecting rod 402, so that the connecting rod 402 can toggle the torsion spring when rotating. After the connecting rod 402 is released, the torsion spring will drive the connecting rod 402 to reset. The connecting rod 402 is L-shaped. There are two clamping blocks 403, which are fixedly connected to the left and right sides of the lower tube 102.

[0033] Among them, the lower cylinder 102 is composed of two half cylinders, and the tops of the two half cylinders are fixedly connected with plug blocks. The upper cylinder 101 is provided with a slot corresponding to the plug block. When the plug block is inserted into the slot, the two half cylinders can be spliced. The chassis 3 is threadedly connected to the movable rod 2, and a plug rod is fixedly installed on the surface of the chassis 3. Fixed grooves are provided at the corresponding plug rods of the two half cylinders. When the chassis 3 is fitted with the sampling cylinder 1, the plug rod will be inserted into the fixed groove, thereby further fixing the two half cylinders.

[0034] When cleaning is required, the movable rod 2 is rotated to drive the chassis 3 to move downward until the insertion rod is disengaged from the fixed groove. Then, the tops of the two connecting rods 402 can be pressed toward the sampling tube 1 to disengage the bottom ends of the connecting rods 402 from the block 403. The lower tube 102 can be moved downward to disengage the insertion block of the lower tube 102 from the slot, so that the lower tube 102 can be split into two half tubes, making it easier to clean its inner wall.

[0035] The surface of the upper cylinder 101 is provided with an assembly component 5, which is used to facilitate the connection and disassembly of the movable rod 2. The assembly component 5 includes a limit rod 501, a support rod 502, a threaded sleeve 503, a fixed rod 504 and a pressing plate 505, wherein the limit rod 501 is fixedly mounted on the surface of the upper cylinder 101, the support rod 502 is sleeved on the outside of the limit rod 501 and fits the surface of the upper cylinder 101, the surface of the threaded sleeve 503 is fixedly connected to the limit rod 501, and the inner wall of the threaded sleeve 503 is threadedly connected to the surface of the movable rod 2, the fixed rod 504 is fixedly connected to the surface of the upper cylinder 101, and the surface of the fixed rod 504 is provided with an anti-slip plate, the pressing plate 505 rotates with the surface of the fixed rod 504, and the pressing plate 505 fits the surface of the support rod 502.

[0036] Since the movable rod 2 is threadedly connected to the chassis 3, the chassis 3 and the movable rod 2 can be disassembled by rotating the chassis 3, and then the pressure plate 505 can be rotated to disengage the pressure plate 505 from the support rod 502. The support rod 502 is no longer restricted by the pressure plate 505, and the threaded sleeve 503 connected to the support rod 502 can be used to drive the movable rod 2 to move, so that the movable rod 2 is pulled out from the top of the upper cylinder 101, thereby facilitating the cleaning of the threaded rod and also facilitating the cleaning of the inner wall of the upper cylinder 101, thereby facilitating the cleaning.

[0037] The working principle of the above embodiment is:

[0038] When it is necessary to collect samples, the movable rod 2 is rotated to drive the bottom plate 3 downward, so that the bottom of the sampling tube 1 is open, and the sampling tube 1 is inserted into the sample to fill the interior of the sampling tube 1. Then, the movable rod 2 is reversed to seal the bottom plate 3 and the sampling tube 1, thereby completing the sampling operation.

[0039] When cleaning is required, the movable rod 2 is rotated to move the chassis 3 downward until the plug is disengaged from the fixed slot. Subsequently, the tops of the two connecting rods 402 can be pressed toward the sampling tube 1 to disengage the bottom ends of the connecting rods 402 from the block 403, and the lower tube 102 can be moved downward to disengage the plug of the lower tube 102 from the slot, thereby splitting the lower tube 102 into two half tubes, which is convenient for cleaning the inner wall. Since the movable rod 2 is threadedly connected to the chassis 3, the chassis 3 can be disassembled from the movable rod 2 by rotating the chassis 3. Subsequently, the pressing plate 505 is rotated to disengage the pressing plate 505 from the support rod 502. The support rod 502 is no longer restricted by the pressing plate 505, and the threaded sleeve 503 connected to the support rod 502 can be used to drive the movable rod 2 to move, so that the movable rod 2 is withdrawn from the top of the upper tube 101, thereby facilitating the cleaning of the threaded rod and the inner wall of the upper tube 101, thereby playing a role in facilitating cleaning.
