Description
Technical Field
[0001] The utility model belongs to the technical field of experimental equipment, and particularly relates to an adjustable connecting device for connecting a suma tank and an automatic sample injector. Background Art
[0002] At present, the Suma tank automatic samplers on the market generally use a hook structure to achieve the connection between the Suma tank and the automatic sampler, such as Qingdao Huankong's GHD-5001 Suma tank automatic sampler, Weishi Technology's V-True216AS automatic sampler, etc. The Suma tank is generally connected by a fixed hook structure set on the automatic sampler. The fixed hook is generally provided with a fixed groove, and the metal ring above the Suma tank is placed in the fixed groove to fix the Suma tank; and multiple (usually two) fixed grooves are set at intervals on the fixed hook to achieve the adaptation of Suma tanks of different specifications.
[0003] However, since most of the existing automatic samplers are mainly adapted to commonly used Suma cans, such as 3L or 6L Suma cans, the existing automatic samplers cannot be well adapted to Suma cans of other specifications and sizes, such as 15L, 2.7L and 1L Suma cans. Although the connection of the Suma can can be achieved by placing the metal ring on the top of the Suma can into the clamping grooves at different positions, the clamping grooves are horizontally arranged on the clamping hooks, resulting in a limited moving distance; and due to the replacement of the clamping grooves, the injection port of the Suma can and the injection interface of the automatic sampler have large deviations and tilts in both the horizontal and vertical positions, resulting in increased connection difficulty. A large force needs to be applied when tightening the bolts, which seriously increases the difficulty of the connection operation, and there is a risk of leakage and poor sealing.
[0004] In addition, metal rings are welded on the top of 3L, 6L, and 15L Summa tanks, but no metal rings are set on the top of 0.5L, 1L, and 2.7L Summa tanks, so that the existing automatic sampler cannot achieve the hanging connection of 0.5L, 1L, and 2.7L Summa tanks through the above-mentioned fixed hook structure.
[0005] Therefore, it is necessary to design an adjustable connecting device for connecting the Summa tank and the automatic sampler, which can adapt to Summa tanks of different specifications and sizes, is easy to use, has low connection difficulty, and has strong stability. Summary of the invention
[0006] In order to solve the above technical problems, the utility model proposes an adjustable connecting device for connecting a Suma jar and an automatic sampler. The utility model has a simple structure and is easy to use. The utility model can adapt to Suma jars of various sizes and specifications so that the Suma jar can be stably and reliably fixed on the automatic sampler. The position of the Suma jar can be changed by moving the card top plate up and down so that the sample inlet of the Suma jar and the interface of the automatic sampler are close to each other, avoiding large misalignment between the two, thereby reducing the difficulty of connection.
[0007] The technical solution of the utility model is:
[0008] The utility model provides an adjustable connection device for connecting a Suma can and an automatic sampler, wherein the automatic sampler is provided with a fixing hook for fixing the Suma can, and the fixing hook is provided with two adjacent fixing grooves, including:

DETAILED DESCRIPTION
[0035] In order to enable those skilled in the art to better understand the present invention, the present invention is now further described in conjunction with specific implementation methods.
[0036] Embodiment 1:
[0037] like Figure 1~Figure 4 As shown, the utility model provides an adjustable connecting device for connecting a Summa jar and an automatic sampler, including a receiving seat, a plate sleeve 4, and a clamping top plate 5. The receiving seat and the plate sleeve 4 are an integrated structure. The plate sleeve 4 is sleeved on the outer periphery of the clamping top plate 5 and the clamping top plate 5 can move up and down. The automatic sampler 1 is provided with a clamping hook 11 for clamping the Summa jar 2. The clamping hook 11 is provided with two adjacent clamping grooves 111. The automatic sampler 1 and the Summa jar 2 are both mature existing technologies, and the specific structure will not be repeated here.
[0038] like Figure 1 , Figure 2As shown, the socket seat 3 is provided with an opening connected with the upper and lower parts, and the cross section of the socket seat 3 is in the shape of a "コ", that is, the socket seat 3 is formed by connecting the front side plate, the connecting plate, and the rear side plate in sequence, the front side plate is parallel to the rear side plate and both are vertically fixedly connected to the connecting plate, and the side walls on the front and rear sides of the socket seat 3 are provided with socket through holes 31 adapted to the fixing hooks 11 of the automatic sampler 1, and the side walls on the front and rear sides of the socket seat 3 can be embedded in the fixing groove 111, that is, the thickness of the side walls on the front and rear sides of the socket seat 3 is not greater than the width of the fixing groove 111.
[0039] The plate sleeve 4 is arranged on the left side of the socket seat 3 and is fixedly connected to the side wall on the left side of the socket seat 3. The plate sleeve 4 has upper and lower openings and is provided with a longitudinal through groove 41 connecting the upper and lower openings. The card top plate 5 is movably inserted into the longitudinal through groove 41. The length of the card top plate 5 is greater than the length of the plate sleeve 4. Its specific length can be determined according to the distance between the injection interface of the automatic sampler 1 and the fixing hook 11, and the size of the metal ring 21 on the top of the 3L~15L Suma tank 2, so that the card top plate 5 can realize the injection port of the Suma tank 2 and the injection interface of the automatic sampler 1 facing each other during movement, thereby reducing the difficulty of connecting the two.
[0040] The plate sleeve 4 is provided with a locking member 42 penetrating its side wall. Two locking members 42 are provided. Specifically, the locking members 42 are tightening screws. The tightening screws can be rotated to make them contact and squeeze the internal card top plate 5, so as to limit the upward and downward movement of the card top plate 5 and play a locking and limiting effect.
[0041] like Figure 1 As shown, both ends of the card top plate 5 are provided with card top grooves 51, and the opening of the card top groove 51 is arranged on the rear side of the card top plate 5, that is, the opening of the card top groove 51 faces the automatic sampler 1, and the card top groove 51 is arranged to be tilted downward to prevent the metal ring 21 on the top of the Suma tank 2 from falling off easily, thereby improving the stability and reliability of the connection.
[0042] Specific usage status reference Figure 3 and Figure 4 , the figure takes the connection of a 15L Suma tank 2 as an example. When the connection device of this embodiment is not used, the injection port of the 15L Suma tank 2 is located below the injection structure of the automatic sampler 1, and because the metal ring 21 of the 15L Suma tank 2 is placed in the fixing groove 111 located on the outside of the fixing hook 11, the axis of the injection port of the Suma tank 2 is tilted downward, and is at a large inclination angle with the axis of the horizontal injection interface of the automatic sampler 1. At this time, the connection is difficult and it is not convenient for the operator to tighten the bolts. After adopting the connection device in this embodiment, Figure 3 and Figure 4As shown, the Summa tank 2 is lifted upward to a certain height as a whole, so that the injection port of the Summa tank 2 and the injection interface of the automatic sampler 1 are approximately on the same horizontal line, which greatly shortens the longitudinal distance between the two and the inclination angle of the axis of the two, thereby facilitating the tightening and connection of the bolts of the two.
[0043] Embodiment 2:
[0044] For Example 2 of the utility model, Figure 5~Figure 7 Note that description of parts that are not different from those in Embodiment 1 will be omitted and will be given the same reference numerals.
[0045] like Figure 5 As shown, the utility model relates to an adjustable connecting device for connecting a Suma jar and an automatic sampler, wherein a clamping assembly 6 is arranged at the lower end of a card top plate 5 near its end position, and the clamping assembly 6 includes an upper top plate 61 and a lower bottom plate 62 fixedly connected to the card top plate 5, and a clamping plate 63 movably arranged between the upper top plate 61 and the lower bottom plate 62.
[0046] The clamping plate 63 is connected to the upper plate 61 through a clamping piece 7. The clamping piece 7 is fixedly connected to the clamping plate 63, and the clamping piece 7 is movably connected to the upper plate 61. Specifically, the clamping piece 7 includes a movable shaft and a spring sleeved on the outer circumference of the movable shaft. The movable shaft can be moved up and down through the upper plate 61. The bottom end of the movable shaft is fixedly connected to the clamping plate 63, and the top end is provided with a pulling end head. The two ends of the spring are respectively abutted against the lower end surface of the upper plate 61 and the upper end surface of the clamping plate 63 (not shown in the figure). The lifting end head is pulled upward to drive the clamping plate 63 to move upward, and then the feeding end of the Suma tank 2 is placed in the gap between the clamping plate 63 and the lower bottom plate 62. The lifting end head is released, and the clamping plate 63 is squeezed downward under the action of the spring, and acts together with the lower bottom plate 62 to achieve clamping and pressing of the Suma tank 2.
[0047] Specific usage status reference Figure 6 and Figure 7 The figure takes a 1L Summa tank 2 as an example, and the specific clamping position of the clamping assembly 6 is the connection end position of the diaphragm air valve of the Summa tank 2. It can be seen from the figure that after the clamping of the Summa tank 2 is completed, the upper and lower positions of the card top plate 5 can be adjusted to make the sample inlet of the Summa tank 2 and the feed interface of the automatic sampler 1 at the same horizontal height, thereby facilitating the connection between the two.
[0048] Embodiment 3:
[0049] For Example 3 of the utility model, Figure 8 Note that description of parts that are not different from those in Embodiment 1 will be omitted and will be given the same reference numerals.
[0050] like Figure 8As shown, the utility model relates to an adjustable connecting device for connecting a Summa jar and an automatic sampler, wherein the cross-section of the socket 3 is in the shape of a "mouth", that is, the socket 3 is a sleeve-like structure with upper and lower openings, and two groups of plate sleeves 4 and card top plates 5 are provided, the plate sleeves 4 are arranged on the left and right sides of the socket 3 and are fixedly connected to the left and right side walls thereof, and by arranging the card top plates 5 and the plate sleeves 4 on both the left and right sides, the stability and reliability of the connection of the Summa jar 2 can be greatly improved, and the risk of falling or detaching due to shaking caused by accidental touch can be avoided.
[0051] To sum up, the adjustable connecting device for connecting the Suma jar and the automatic sampler provided by the utility model has a simple structure and is easy to use. It can be adapted to Suma jars of various sizes and specifications so that the Suma jar can be stably and reliably fixed on the automatic sampler, and the position of the Suma jar can be changed by moving the card top plate up and down, so that the injection port of the Suma jar and the interface of the automatic sampler are close to each other, avoiding large misalignment between the two, thereby reducing the difficulty of connection.
[0052] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent changes and modifications made within the scope of the present invention should still fall within the scope of the present invention.
