Description

Technical Field

[0001] The utility model relates to the technical field of cover opening and closing instruments, in particular to a semi-automatic microwave digestion tank cover opening and closing instrument. Background Art

[0002] Existing microwave digestion tanks are fixed by tightening through threaded ports, usually manually, with the tool provided at most to increase the lever arm, but this is quite strenuous overall. Firstly, when there are a large number of samples, repeated twisting is detrimental to the health of the experimenters, and can easily lead to occupational diseases such as tenosynovitis and strain, and is also very time-consuming. Moreover, after the digestion tank has been subjected to high temperature and high pressure, the lid is even more difficult to unscrew. Secondly, the tool only has two fixing teeth, while the lid has 12 corresponding grooves, which makes it easier to slip. Utility Model Content

DETAILED DESCRIPTION

[0020] 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.

[0021] The present invention provides a semi-automatic microwave digestion tank lid opening and closing instrument. Figure 1-4 As shown, it comprises a base 1, upright pole 1 2, upright pole 2 13, two folded-line guideways 3, two fixing bases 5, and multiple elastic cords 4. Both upright pole 1 2 and upright pole 2 13 are mounted on top of the base 1, with the two folded-line guideways 3 symmetrically positioned on top of upright pole 1 2 and upright pole 2 13. Two fixing bases 5 are positioned at the top and bottom of the folded-line guideways 3, respectively, with multiple elastic cords 4 equally spaced between the two fixing bases 5. The elastic cords 4 are positioned between the two folded-line guideways 3, within which a canister 7 is positioned. The top of the canister 7 is threadedly engaged with a top cover 6, which has retaining grooves 8 on its sides.

[0022] The system also includes a vertical slide 9, a drive slider 10, a motor 11, a sleeve 26, and a plurality of telescopic rods 21. The vertical slide 9 is vertically mounted on the top of the base 1, and the drive slider 10 is slidably engaged with the vertical slide 9. The motor 11 is mounted on the bottom of the drive slider 10, and the mounting plate 20 is sleeved onto the motor 11. The sleeve 26 is mounted on the output end of the motor 11, and a plurality of telescopic rods 21 are equiangularly distributed on the bottom of the mounting plate 20. The movable ends of the telescopic rods 21 extend through and into the sleeve 26, and the telescopic rods 21 are adapted to fit within the latch grooves 8.

[0023] It also includes a sensor 19, a card plate 18 and a roller 17. The sensor 19 is arranged on the bottom end of the folding line card channel 3, and the card plate 18 and the roller 17 are arranged on the vertical rod 2. The elastic line 4 passes around the card plate 18 and the roller 17 respectively.

[0024] The invention also comprises a transverse slide 16 and an auxiliary driving slider 25. The transverse slide 16 is laterally arranged on the side of the folding line card channel 3, and the auxiliary driving slider 25 is slidably matched on the transverse slide 16.

[0025] The system also includes a secondary electric telescopic rod 24, a mounting rod 23, a wedge block 22, and a connecting seat 12. The secondary electric telescopic rod 24 is mounted on the secondary drive slider 25, and the connecting seat 12 is mounted on the movable end of the secondary electric telescopic rod 24. The mounting rod 23 is mounted on the connecting seat 12, and the wedge block 22 is mounted on the mounting rod 23. The wedge block 22 corresponds to the gap between two adjacent tanks 7.

[0026] The electric telescopic rod 15 and the supporting plate 14 are also included. The electric telescopic rod 15 is arranged on the base 1. The supporting plate 14 is arranged on the movable end of the electric telescopic rod 15. The supporting plate 14 corresponds to the bottom of the branch road in the horizontal direction of the folding line card road 3.

[0027] Working Principle: When in use, multiple tanks 7 are first fed into the height of the folding track 3. Multiple elastic lines 4 are used to adaptively support the tanks 7. The slider 10 is then driven downward and aligned with the tank 7 closest to the sensor 19. The electric telescopic rod 15 then operates, causing the support plate 14 to move upward, leaving a certain amount of space between the support plate 14 and the elastic line 4. Simultaneously, the secondary electric telescopic rod 24 is controlled to retract, allowing the wedge block 22 to insert into the gap between adjacent tanks 7, separating the two adjacent tanks 7. Next, when the drive slider 10 is lowered, the sleeve 26 driven by it moves downward and engages with the top cover 6. Simultaneously, the telescopic rod 21 is controlled to pass through the sleeve 26 and engage with the card groove 8. If a tooth collision occurs, due to the space left between the support plate 14 and the elastic line 4, when the sensor 19 detects that the tank 7 has moved too far downward, the drive slider 10 is immediately stopped. The motor 11 then rotates, unscrewing the top cover 6 from the tank 7.

[0028] When personnel need to clean this device, since there are multiple elastic lines 4 between the two fold line channels 3, the cleaning difficulty is greatly reduced compared with the inner walls of other slide seats. At the same time, personnel only need to pull the elastic lines 4 apart to clean the bottom inner wall, which will neither cause water accumulation nor cause the problem of personnel's brush being difficult to insert due to the slide being too narrow.

[0029] In summary, the semi-automatic microwave digestion tank lid opening and closing instrument utilizes a base 1, upright 1 2, upright 2 13, two folded-line latches 3, two fixing bases 5, and multiple elastic cords 4, all working in concert. This allows the present invention to utilize more latches for locking the tank lid, while also replacing manual operation with motor rotation, significantly improving work efficiency. Furthermore, to address the increased likelihood of tangs between the latches and the sides of the tank lid caused by multiple latches, the present invention employs elastic cords 4 and a support plate 14 to continuously compress the tank lid for tentative insertion. Furthermore, the deformable elastic cords 4 also provide cushioning against the latches.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
