Description
Technical Field
[0001] The invention belongs to the technical field of clamping equipment for sanitary tanks, and in particular relates to a clamping connector for sanitary tanks. Background Art
[0002] Sanitary connectors are widely used in places that require high hygiene and no pollution. They are usually used in food, pharmaceuticals, bioengineering, chemicals and other industries that require strict pollution control. In the food processing process, sanitary connectors are widely used in the connection of equipment such as pipelines, storage tanks, reactors, etc. They can ensure the safety and hygiene of food during production, transportation and storage. In the pharmaceutical process, sanitary connectors are used to connect pharmaceutical equipment, pipelines and storage tanks. They can ensure the purity and sterility of drugs during production, transportation and storage, thereby improving the quality and safety of drugs. In the field of bioengineering, sanitary connectors also play an important role. They are used to connect equipment such as bioreactors and fermenters to ensure the accuracy and reliability of biological experiments.
[0003] Conventionally used storage tanks, reaction tanks, fermentation tanks, etc., in order to ensure their sealing performance and connection stability, are usually fastened with bolts. However, due to the thread setting of the bolt connection, materials will remain in the gap of the threaded connection, which is difficult to clean, causing microbial contamination or impurity contamination, which does not meet the 3-A sanitary standard (an internationally recognized sanitary standard established by the American 3-A Sanitary Standards Company); at the same time, traditional connectors are time-consuming and laborious in the process of tightening operations, and often require other tools (screwdrivers, wrenches, pliers, etc.) to assist in tightening, and the difference between each operator will cause different degrees of tightening, which is easy to cause over-tightening or under-tightening, resulting in inconsistent tightening between different connection points, reducing the connection strength of each connection point of the tank body, and then there is a risk of loose connection, reducing the overall stability of the tank body, making the tank body more prone to failure when subjected to external force, and reducing the service life of the tank body. In this regard, a sanitary tank clamp connector is proposed for improvement. Summary of the invention

DETAILED DESCRIPTION
[0018] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.
[0019] Example: like Figure 1-7 As shown, this embodiment provides a sanitary tank clamp connector, including a tank body 1, an output pipe 2 is provided on the tank body 1, the output pipe 2 is connected to the delivery pipe 3, a clamp ring 4 is provided at the connection between the output pipe 2 and the delivery pipe 3, and a clamp 5 is provided on the outer cover of the clamp ring 4, the clamp 5 includes a first half ring 6 and a second half ring 7 that are symmetrically arranged, one end of the first half ring 6 and the second half ring 7 are kept in rotational connection, and the other ends are respectively integrally provided with a first connecting plate 8 and a second connecting plate 9, and the first connecting plate 8 and the second connecting plate 9 are penetrated with a clamp hole 11; A clamping member 12 is inserted into the clamping hole 11. The clamping member 12 has an insert rod 14. A limit plate 15 is fixedly installed on the top of the insert rod 14. A screwing member 16 is integrally provided on the limit plate 15. A limit groove 17 is also slotted at the bottom of the insert rod 14. A limiting member 13 is fixedly mounted on the lower end surface of the second connecting plate 9 . An inserting slot 20 is formed through an opening in the middle of the limiting member 13 , and limiting plates 21 are symmetrically provided at both ends.
[0020] In a specific application scenario, during the use of the sanitary tank snap-in connector, the snap-in connector 12 is first inserted into the snap hole 11, and the sealing ring 19 and the insertion groove 20 are penetrated. During the insertion process, it passes between the two turning parts 22 and squeezes the two turning parts 22 apart. At this time, since the slots on the insertion rod 14 are provided with limit grooves 17, the limit sheet 21 releases its elasticity and resets, thereby driving the turning part 22 to be stuck in the limit groove 17 and fit in the limit groove 17, forming a stable holding and support for the limit member 13, and then The first connecting plate 8 and the second connecting plate 9 between the limiting member 13 and the limiting plate 15 are clamped by the limiting member 13 and the limiting plate 15, so that the connection between the first connecting plate 8 and the second connecting plate 9 is kept stable; and the hand-held screwing member 16 is pulled synchronously during the process of screwing the clamping member 12, so that the insertion rod 14 squeezes the two turning parts 22 again through the rod body during the rotation process, thereby driving the limiting groove 17 to separate from the turning part 22, and releasing the limiting and connection of the first connecting plate 8 and the second connecting plate 9. The following is a further description of the sanitary tank clamping connector of the present invention in combination with this application scenario.
[0021] Further, refer to Figure 1-7 A sealing ring 19 with a central opening is also provided between the first connecting plate 8 and the second connecting plate 9 , and the card hole 11 , the plug-in groove 20 , and the central opening of the sealing ring 19 are all penetrated by the insertion rod 14 .
[0022] In this embodiment, during the process of pipeline connection of the output pipe 2 and the delivery pipe 3, in order to maintain a close fit between the first connecting plate 8 and the second connecting plate 9 and improve the clamping effect of the output pipe 2 and the delivery pipe 3, a sealing ring 19 is arranged between the first connecting plate 8 and the second connecting plate 9, so as to utilize the bearing capacity and buffering capacity of the sealing ring 19 for buffering, and can also effectively prevent the leakage of liquid, gas or solid substances, thereby ensuring the connection sealing between the first connecting plate 8 and the second connecting plate 9, and then improving the integrity and safety of the pipeline connection between the first connecting plate 8 and the second connecting plate 9; at the same time, in order to make the first connecting plate 8 and the second connecting plate 9 located in the same vertical direction after the clamping member 12 is inserted through the first connecting plate 8 and the second connecting plate 9, the clamping hole 11, the plug-in groove 20, and the middle opening of the sealing ring 19 are all penetrated by the insertion rod 14 to maintain a stable connection.
[0023] For more details, see Figure 1-7 The diameter of the insert rod 14 matches the diameter of the card hole 11 and the inserting groove 20 .
[0024] In this embodiment, after the insertion rod 14 is inserted through the card hole 11 and the plug-in groove 20, in order to avoid a gap between the outer circumferential wall of the insertion rod 14 and the hole wall of the card hole 11 and the plug-in groove 20, which causes shaking and deviation, the diameter of the insertion rod 14 is set to match the diameter of the card hole 11 and the plug-in groove 20, so that the insertion rod 14 fits into the hole wall of the card hole 11 and the plug-in groove 20 after being inserted through the card hole 11 and the plug-in groove 20, thereby maintaining stable insertion.
[0025] More preferably, referring to Figure 1-7 , the diameter of the limiting plate 15 is larger than the diameter of the clamping hole 11.
[0026] In this embodiment, in order to limit the upper end surface of the first connecting plate 8 by the limiting plate 15, the diameter of the limiting plate 15 is set to be larger than the diameter of the clamping hole 11, so that after the lower end surface of the limiting plate 15 contacts the upper end surface of the first connecting plate 8, the limiting plate 15 is prevented from slipping out of the clamping hole 11, causing the separation of the clamping member 12 and the first connecting plate 8, so that the limiting plate 15 cooperates with the limiting member 13 to respectively contact and clamp the upper end surface of the first connecting plate 8 and the lower end surface of the second connecting plate 9, thereby maintaining the connection between the first connecting plate 8 and the second connecting plate 9 stable, and improving the clamping effect of the connecting ports of the output pipe 2 and the delivery pipe 3.
[0027] More preferably, referring to Figure 1-7 The screwing member 16 is provided with a through hole for simultaneous pulling during the hand-held screwing process.
[0028] In the present embodiment, since the connection piece needs not only to be screwed but also lifted during separation, in order to facilitate the user to exert force, a through hole is opened on the screw piece 16 for simultaneous lifting during the hand-held screwing process, thereby improving the convenience of using the connection piece, and the connection between each connection point is achieved by rotating the screw piece 16, so that the connection between the first connection plate 8 and the second connection plate 9 is achieved through the same structure, thereby maintaining the same degree of tightness between the connection points.
[0029] Furthermore, refer to Figure 1-7 The limiting piece 21 is made of metal and has elasticity.
[0030] In this embodiment, in order to enable the limiting plate 21 to not only store force and deform after being squeezed, but also to have a stable supporting ability through its own metal material, the limiting plate 21 is made of metal material and has elasticity, so that after the limiting plate 21 is squeezed, the two turning parts 22 are driven to separate towards each other to allow the hemispherical protrusion 18 to pass through; at the same time, the limiting plate 21 can also be reset through its own elasticity to engage with the limiting groove 17.
[0031] Furthermore, refer to Figure 1-7A turning portion 22 and a resisting portion 23 are integrally formed at the bottom of the limiting piece 21 . The turning portion 22 is in contact with the side wall of the limiting groove 17 , and the resisting portion 23 resists with the bottom wall of the limiting groove 17 .
[0032] In this embodiment, after the bottom end of the clamping member 12 completely passes through the two turning parts 22, since the insertion rod 14 is also grooved with a limiting groove 17, the extrusion posture of the two turning parts 22 cannot be maintained by the rod body, so that the limiting plate 21 releases its elasticity and resets at this time, thereby driving the turning part 22 to be stuck into the limiting groove 17 and fit with the limiting groove 17. At the same time, the interference portion 23 at the bottom of the limiting plate 21 also forms a stable holding and support for the limiting member 13 through the interference with the bottom wall of the limiting groove 17, so that the first connecting plate 8 and the second connecting plate 9 between the limiting member 13 and the limiting disk 15 are clamped by the limiting member 13 and the limiting disk 15, so as to maintain the stable connection between the first connecting plate 8 and the second connecting plate 9.
[0033] More specifically, see Figure 1-7 The limiting piece 21 is tilted and its tilt angle matches the top of the limiting groove 17 .
[0034] In this embodiment, in order to enable the limiting plate 21 to be inserted into the limiting groove 17 at an angle, and then drive the turning part 22 to engage with the limiting groove 17, the limiting plate 21 is tilted and the tilt angle is adapted to the top of the limiting groove 17. Therefore, during the insertion of the insertion rod 14, the limiting plate 21 and the turning part 22 are inserted into the limiting groove 17 step by step, avoiding friction or jamming, and maintaining smooth insertion of the turning part 22 into the limiting groove 17.
[0035] More specifically, see Figure 1-7 A hemispherical protrusion 18 is also integrally formed at the bottom end of the insertion rod 14 , and the diameter of the hemispherical protrusion 18 is greater than the distance between the two turning parts 22 .
[0036] In this embodiment, in order to allow the bottom end of the insertion rod 14 to be inserted between the two turning parts 22 and to simultaneously squeeze the two turning parts 22 to force the two turning parts 22 to separate, a hemispherical protrusion 18 with a diameter greater than the distance between the two turning parts 22 is provided at the bottom end of the insertion rod 14, so that the two turning parts 22 can be fully squeezed apart through the hemispherical setting of the hemispherical protrusion 18, and the friction force during the squeezing process can be reduced, thereby keeping the insertion of the insertion rod 14 smooth.
[0037] More specifically, see Figure 1-7 The inner walls of the first half ring 6 and the second half ring 7 are both grooved with a clamping groove 10, the width of the clamping groove 10 is matched with the sum of the widths of the two clamping rings 4, and the inner side wall of the clamping groove 10 is provided with a rubber gasket.
[0038] In this embodiment, in order to maintain the sealing effect on the connection ports of the output pipe 2 and the delivery pipe 3, the width of the card slot 10 is set to match the sum of the widths of the two clamping rings 4, and a rubber gasket is provided on the inner side wall of the card slot 10, so that the card slot 10 can completely wrap the two clamping rings 4 while further improving the sealing performance through the rubber gasket.
[0039] Working principle: The clamping connector for sanitary tanks of the present invention, in the process of connecting the output pipe 2 and the delivery pipe 3, firstly, the clamp ring 4 provided at the connection ends of the output pipe 2 and the delivery pipe 3 is inserted into the clamp 5, and the first half ring 6 and the second half ring 7 provided at the clamp 5 wrap the clamp ring 4 by rotating at one end, and the first connecting plate 8 and the second connecting plate 9 provided at the other ends of the first half ring 6 and the second half ring 7 form a conflict, and a sealing ring 19 is provided between the first connecting plate 8 and the second connecting plate 9 to form a buffer while maintaining the sealing performance when the first connecting plate 8 and the second connecting plate 9 conflict, at this time, the sealing performance is further improved by the clamping groove 10 provided on the inner wall of the first half ring 6 and the second half ring 7 and the rubber gasket provided, so as to keep the pipeline connection of the output pipe 2 and the delivery pipe 3 tight; Then, in order to maintain the connection between the output pipe 2 and the delivery pipe 3 and to prevent the first connecting plate 8 and the second connecting plate 9 from being separated, a clamping piece 12 is arranged to be inserted into the clamping hole 11, and the sealing ring 19 and the plug groove 20 are inserted, so that the first connecting plate 8 and the second connecting plate 9 are in the same vertical direction. Then, in order to prevent the clamping piece 12 from falling off, a hemispherical protrusion 18 at the bottom end of the insertion rod 14 is arranged to pass between the two turning parts 22 during the insertion process, and the two turning parts 22 are squeezed apart, so that the two inclined limiting plates 21 are deformed and stored by their own elasticity; and after the hemispherical protrusion 18 completely passes between the two turning parts 22, it drives the lower end surface of the limiting plate 15 to contact the upper end surface of the first connecting plate 8. At this time, due to the insertion rod 14 The upper portion is also provided with a limiting groove 17, so that the extrusion posture of the two turning parts 22 cannot be maintained by the rod body, so that the limiting piece 21 releases its elasticity and resets at this time, thereby driving the turning part 22 to be stuck in the limiting groove 17 and fit the limiting groove 17, and at the same time, the abutment portion 23 at the bottom of the limiting piece 21 also forms a stable holding and support for the limiting member 13 through the abutment with the bottom wall of the limiting groove 17, so that the first connecting plate 8 and the second connecting plate 9 between the limiting member 13 and the limiting plate 15 are clamped by the limiting member 13 and the limiting plate 15, so that the connection between the first connecting plate 8 and the second connecting plate 9 is kept stable, and each connection point is connected by the same structure, so that the fastening degree between each connection point is kept consistent; When it is necessary to release the connection between the first connecting plate 8 and the second connecting plate 9, the screwing piece 16 can be held in hand and pulled synchronously during the process of screwing the clamping piece 12 by cooperating with the through hole on the screwing piece 16, so that the insertion rod 14 can squeeze the two turning parts 22 again through the rod body during the rotation, thereby driving the limiting groove 17 to separate from the turning part 22, so that the insertion rod 14 and the hemispherical protrusion 18 can be pulled out from between the two turning parts 22, and then pulled out by the user, thereby releasing the limitation and connection between the first connecting plate 8 and the second connecting plate 9.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
