[0028] Specifically, ton boxes and liquid bags are commonly used methods for transporting and storing liquid materials. Ton boxes are generally standard cubes or rectangular boxes. The upper surface of the ton box is not capped. The liquid bag is placed in the ton box, and the liquid material is poured into the liquid bag from the feed port, and is pumped out from the feed port of the liquid bag with a pump; the support frame 100 is composed of but not limited to stainless steel pipes, square steels, square tubes and other components welded together, and the fixing assembly 200 is composed of a structure that matches the size of the support frame 100. For example, when the support frame 100 is a square tube, the fixing assembly 200 uses a square tube with cross-sectional dimensions on both sides larger than the square tube of the support frame 100. The square tube is bolted or a steel plate is welded on it, and an opening of the same size as the bag opening of the liquid bag is opened on the steel plate.

[0029] The clamping assembly 300 is arranged at both ends of the support frame 100, and the first clamping plate 310 and the second clamping plate 320 are made of steel plates of the same size.

[0031] The technical solution of the clamping and fixing device for the bag mouth of the ton container liquid bag adopted in this application can achieve the following beneficial effects:

[0032] 1. By setting the first clamping plate 310 and the second clamping plate 320, the support frame 100 is clamped on the side wall of the ton box as a whole, so as to improve the stability of the support frame 100. At the same time, the problem that the support frame 100 is easy to move when the pumping force is large and the pipeline shakes violently, thereby causing the support frame 100 to detach from the ton box, causing the liquid outlet of the liquid bag to shift, and the extracted liquid material is easy to spill and cause waste.

[0033] 2. One end of the first fastening bolt 330 is rotatably connected to the second clamping plate 320, and the other end passes through the first clamping plate 310 and is threadedly connected thereto, so that the operation is simpler and the distance between the first clamping plate 310 and the second clamping plate 320 is more convenient to adjust.

[0034] 3. The first clamping plate 310 and the second clamping plate 320 can slide on the support frame 100, so that it can be applied to tonnage boxes of any size, thereby improving applicability, and the first clamping plate 310 and the second clamping plate 320 can be detachably connected to the side wall of the tonnage box, and are easy to remove and install. In addition, the present application is light in weight and easy to carry, which improves the efficiency of field extraction and ensures safety during extraction.

[0035] Based on the above solution, in order to achieve a more stable installation, the clamping assembly 300 includes a second fastening bolt 340 , which passes through an end of the first clamping plate 310 away from the first fastening bolt 330 and is threadedly connected to the first clamping plate 310 .

[0036] Specifically, a second through hole for the second fastening bolt 340 to pass through is provided at one end of the first clamp 310 away from the first fastening bolt 330, and a nut matching the second fastening bolt 340 is provided at one end of the second through hole away from the second clamp 320. When the first clamp 310 and the second clamp 320 are tightly attached to the inner and outer sides of the side wall of the ton box, the second fastening bolt 340 is rotated to make one end of the second fastening bolt 340 contact and clamp with the side wall of the ton box, so that the upper and lower ends of the first clamp 310 are fastened to the side wall of the ton box, thereby improving the connectivity between the present application and the ton box and making the connection more stable, thereby improving the pull-out resistance of the first clamp 310 and the second clamp 320.

[0037] In the above solution, a backing plate 341 is provided at one end of the second fastening bolt 340, and a flexible rubber pad 342 is provided on the backing plate 341. For example, a pit is provided at one end of the second through hole away from the nut, the backing plate 341 uses a circular structure, and one end is connected to the second fastening bolt 340, and the flexible rubber pad 342 is fixed to the end of the backing plate 341 away from the second fastening bolt 340 by means of, but not limited to, glue, threaded connection, etc., and after the second fastening bolt 340 is rotated outward, the flexible rubber pad 342 and the backing plate 341 are received in the pit, and when the second fastening bolt 340 is rotated, the side of the flexible rubber pad 342 away from the backing plate 341 slowly extends out of the pit. It is tightly attached to the side wall of the ton box, and by setting a pad 341, the contact area between the second fastening bolt 340 and the ton box is increased, reducing the damage to the side wall of the ton box caused by concentrated force, while increasing the friction between the second fastening bolt 340 and the side wall of the ton box, thereby improving the pull-out resistance of the first clamping plate 310; by setting a flexible rubber pad 342, it is avoided that the pad 341 will not leave a mark that is difficult to recover after contacting the side wall of the ton box, thereby causing damage to the ton box.

[0038] In a preferred embodiment, the support frame 100 includes at least two cross bars 110 and two connecting bars 120 . The two connecting bars 120 are disposed at both ends of the two cross bars 110 and are fixedly connected below the cross bars 110 .

[0039] Specifically, the support frame 100 includes two cross bars 110 made of steel pipes and two connecting rods 120 made of angle steels. The two connecting rods 120 are respectively welded at the two ends of the two cross bars 110, so that the support frame 100 forms a standard rectangle. Four first clamps 310 and four second clamps 320 are respectively arranged at the two ends of the two cross bars 110, and are both between the two connecting rods 120. Correspondingly, the first through holes on the first clamps 310 and the second clamps 320 are both circular, and the diameter is slightly larger than the diameter of the cross bars 110. By setting two cross bars 110, the sliding of the fixing assembly 200 is more stable, and the fixing part will not be offset when sliding; by setting two connecting rods 120, the stability of the support frame 100 is enhanced, and at the same time, the problem of the first clamps 310 and the second clamps 320 detaching from the cross bars 110 when sliding is solved.

[0040] Based on the above solution, screw rods 111 are disposed at both ends of the crossbar 110 , and a fastening sleeve 112 is threadedly connected to the screw rod 111 , and the fastening sleeve 112 is matched and connected with the first clamping plate 310 .

[0041] Screws 111 are welded to both ends of the cross bar 110 (the length of the screws 111 is selected according to the size of the tonnage box), and one end of the screws 111 away from the cross bar 110 is fixedly connected to the connecting rod 120. The fastening sleeve 112 adopts but is not limited to a lengthened nut, a round tube with an internal thread, and the like. The fastening sleeve 112 can move on the screw 111 by rotating, and the fastening sleeve 112 is located between the first clamping plate 310 and the connecting rod 120. When the side wall of the tonnage box is between the first clamping plate 310 and the second clamping plate 320, the fastening sleeve 112 is rotated so that the fastening sleeve 112 moves along the screw 111 to the first clamping plate 310. When the plate 310 moves and the fastening sleeve 112 contacts one side of the first clamp plate 310, it drives the first clamp plate 310 to move toward the side wall of the tonnage box until the first clamp plate 310 is in close contact with the tonnage box, then the rotation of the fastening sleeve 112 is stopped, and then the first fastening bolt 330 is rotated to make the second clamp plate 320 approach the first clamp plate 310 until the second clamp plate 320 stops in close contact with the side wall of the tonnage box (the operation is the opposite when dismantling). By setting the screw 111 and the fastening sleeve 112, the first clamp plate 310 is fixed more firmly, thereby solving the problem of the first clamp plate 310 being displaced when the first fastening bolt 330 rotates.

[0042] In a preferred embodiment, the fixing assembly 200 includes at least two sleeves 210, a fixing plate 220 and a clamping plate 230. The sleeve 210 is slidably connected to the cross bar 110, the fixing plate 220 is fixedly connected above the sleeve 210, the clamping plate 230 is detachably connected to one end of the fixing plate 220, and a groove 231 is provided on the fixing plate 220.

[0043] Specifically, the diameter of the sleeve 210 is slightly larger than the diameter of the cross bar 110, so that it can slide smoothly on the cross bar 110, and a rubber ring and a ball can be sleeved in the gap between the sleeve 210 and the cross bar 110, the rubber ring is fixedly connected to the sleeve 210, the ball is embedded in the rubber ring and can rotate, the ball is rotatably connected to the cross bar 110, the fixing plate 220 is welded to the top of the sleeve 210 to form a whole, at least two bolt holes are set at one end of the fixing plate 220, and the clamping plate 230 is detachably connected to the fixing plate 220 by screws, and several types of clamping plates 230 are set, and the groove 231 on each clamping plate 230 corresponds to the shape and size of a bag mouth of a liquid bag. By replacing the clamping plates 230 with different grooves 231, liquid bags with bag mouths of different shapes and sizes are suitable; when the tonnage When the side wall is between the first clamping plate 310 and the second clamping plate 320, the sleeves 210 of the two fixing components 200 are slid from the center to the two sides respectively, and the position of the support frame 100 is adjusted so that the bag opening of the liquid bag is located between the two cross bars 110 and in the center of the cross bars 110, and the fixing components 200 on both sides are slid toward the center so that the grooves 231 on the card plate 230 are respectively close to the two sides of the bag opening of the liquid bag, and they are fixed on the card plate 230; by setting the sleeve 210, the fixing component 200 can slide along the cross bar 110, and at the same time solve the problem of the fixing component 200 being separated from the cross bar 110, and by the detachably connected card plate 230, the fixing component 200 can be suitable for bag openings of liquid bags of different shapes and sizes, which improves practicality and makes the operation simpler and more convenient.

[0044] Based on the above solution, the sleeve 210 is provided with a third fastening bolt 211 , and the third fastening bolt 211 is threadedly connected to the sleeve 210 and is cooperatively connected to the cross bar 110 . For example, a third through hole is opened on the side of each sleeve 210 away from the fixing plate 220, and a nut matching the third fastening bolt 211 is arranged on the side of the third through hole away from the cross bar 110, one end of the third fastening bolt 211 extends into the nut and can rotate and move along the extension direction of the nut, when the sleeve 210 needs to slide along the cross bar 110, the third fastening bolt 211 is rotated outward and retracted; when the sleeve 210 does not need to slide, the third fastening bolt 211 is rotated inward and extended, so that one end of the third fastening bolt 211 contacts the cross bar 110, thereby achieving a fastening effect; by arranging the third fastening bolt 211, the operation is simple and convenient, and the problem of the fixing component 200 sliding back and forth along the cross bar 110 due to external force when fixing the bag mouth of the liquid bag is solved, and at the same time, the problem of the fixing component 200 sliding back and forth during taking and placing and causing damage to the support frame 100 is solved.

[0045] In the above scheme, in order to achieve the purpose of stable clamping, the two fixing components 200 are arranged opposite to each other, and a hook 232 and a hanging ring 233 are provided on the card plate 230.

[0046] Specifically, the two fixing components 200 have the same structure and shape, and are relatively arranged on the cross bar 110. When the two fixing components 200 contact each other, the grooves 231 on the two clamping plates 230 form a shape with the same shape and size as the bag mouth of the liquid bag; hooks 232 and hanging rings 233 (also snap buckles) are hinged on both sides of the clamping plate 230 away from the end of the fixing plate 220, respectively. The hooks on the two opposite clamping plates 230 are clamped on the snap rings to improve the stability of clamping, and at the same time solve the problem that the clamping plate 230 slides to both sides due to the large pumping force, and the bag mouth of the liquid bag is separated from the groove 231. Preferably, the fixing method of the clamping teeth and the rack is used. The rack is connected to one side of one end of the clamping plate 230, and a box body is arranged on the opposite side. The box body is provided with bolts, which penetrate the upper top surface of the box body and can rotate up and down. The end of the bolt extending into the box body is connected to the clamping teeth using a bearing. When the two opposite clamping plates 230 move to the specified position, the rack enters the box body and the bolt is rotated to make the clamping teeth mesh with the rack, thereby playing a fixing role.

[0047] The above-described embodiments only express the way of equipment layout of the present application, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application; it should be pointed out that for ordinary technicians in this field, several adjustments and improvements can be made without departing from the concept of the present application, which all belong to the scope of protection of the present application; therefore, the scope of protection of the patent of this application shall be based on the attached claims.
