Description

Technical Field

[0001] This utility model relates to the field of sealing structure technology, specifically a sealing structure. Background Technology

[0002] In industrial production, sealing devices are typically installed to prevent liquid leakage between the shaft and bearings of compressors or other fluid conveying equipment, and to prevent leakage between the pump shaft and the housing. Common shaft seal types include packing seals, mechanical seals, and rotary shaft seals, which are suitable for sealing various powder and slurry equipment and are widely used in mixing, drying, crystallization, and conveying equipment in multiple industries such as food, pharmaceuticals, chemicals, and metallurgy.

[0003] Currently, all existing rotary shaft seals are equipped with clamps, which drive the rotating ring to rotate. However, existing clamps are basically fastened with screws, which will loosen after a period of use. Once loosened, they can no longer drive the rotating ring to rotate, thus affecting the sealing effect. Utility Model Content

[0004] In view of the above situation and to overcome the existing defects, this utility model provides a sealing structure.

[0005] The present invention provides the following technical solution: A sealing structure proposed in the present invention includes: a fixing seat and a clamping mechanism;

[0006] An end cap is installed on one side of the fixed base. A stationary ring is fixedly installed on both the fixed base and the end cap. A pair of moving rings is installed between a pair of stationary rings. A rubber ring is installed between a pair of moving rings. An elastic component is provided between a pair of moving rings. A pair of corresponding slots are carved on each pair of moving rings.

[0007] The clamping mechanism is mounted on the rubber ring. The clamping mechanism includes a first clamping component and a second clamping component, which are rotatably arranged relative to each other. A first fixing head and a second fixing head are respectively fixed at the ends of the first clamping component and the second clamping component. A first locking tooth is fixed on the side of the first fixing head away from the first clamping component. One end of the first locking tooth passes through the second fixing head and is disposed on the second clamping component. A second locking tooth is fixed on the side of the second fixing head away from the second clamping component. One end of the second locking tooth passes through the first fixing head and is disposed on the first clamping component. An elastic locking block is fixed on both the first fixing head and the second fixing head. The elastic locking block is respectively locked on the first locking tooth and the second locking tooth. The first fixing head and the second fixing head are respectively locked on the two side walls of the locking groove.

[0008] Furthermore, a plurality of first fastening bolts are installed between the fixing seat and the end cover, and the fixing seat and the end cover are fixed together by the first fastening bolts.

[0009] Furthermore, multiple second fastening bolts are installed between the stationary ring and the fixed seat and the end cover, and the pair of stationary rings are fixed to the fixed seat and the end cover respectively by the second fastening bolts.

[0010] Furthermore, a sealing groove is chiseled on the side of the pair of rotating rings near the stationary ring, and a sealing ring is installed in the sealing groove. By setting the sealing ring, the sealing performance between the stationary ring and the rotating ring is effectively improved.

[0011] Furthermore, the elastic component includes multiple mounting slots, which are carved into one of the rotating rings. An elastic body is slidably disposed in each of the mounting slots. The elastic body serves two purposes: firstly, it is inserted into the adapter slot to ensure that the pair of rotating rings rotate synchronously; secondly, it pushes the pair of rotating rings away from each other, so that the pair of rotating rings and the pair of stationary rings can fit tightly together to improve sealing and increase ease of installation. Since the elastic body is already set in the mounting slot, installing another rotating ring only requires aligning the adapter slot with the elastic body.

[0012] Furthermore, another moving ring has an adapter groove corresponding to the mounting groove. One end of the elastic body outside the mounting groove is located in the adapter groove. By having one end of the elastic body outside the mounting groove located in the adapter groove, it is ensured that the pair of moving rings rotate synchronously.

[0013] Furthermore, a groove is chiseled at the bottom of the elastomer, and a spring is installed between the top wall of the elastomer and the bottom wall of the mounting groove. The spring force is used to push the elastomer toward the fitting groove, thereby causing a pair of moving rings to fit together on the stationary ring, moving away from each other.

[0014] Furthermore, a pair of sliding grooves are chiseled in the mounting groove, and a pair of limiting blocks are fixed on the elastic body. The pair of limiting blocks slide in the pair of sliding grooves, thereby limiting the elastic body and preventing the elastic body from being pushed out of the mounting groove due to excessive spring force.

[0015] Furthermore, a first groove is chiseled on the first clamp, and one end of the second tooth on the first clamp slides in the first groove. A second groove is chiseled on the second clamp, and one end of the first tooth on the second clamp slides in the second groove. By setting the first groove and the second groove, the first tooth and the second tooth are prevented from deviating when the first clamp and the second clamp are tightened.

[0016] Furthermore, a control plate is fixed on the elastic block. The control plate is used to lift the elastic block upwards to lift it off the first and second teeth, thereby loosening the first and second clamping components. On the other hand, when the first and second fixing heads are engaged at both ends of the slot, the control plate abuts against the bottom edge of the slot to prevent the elastic block from lifting upwards, thereby preventing the first and second clamping components from loosening.

[0017] The sealing structure proposed by this utility model, which adopts the above structure, can effectively improve the tightness of the clamp, reduce loosening, and facilitate the installation and disassembly of the clamp. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0030] like Figures 1 to 8 As shown, this embodiment provides a sealing structure, including: a fixing seat 1 and a clamping mechanism 2.

[0031] like Figures 1 to 5 As shown, an end cap 101 is installed on one side of the fixed base 1. The fixed base 1 and the end cap 101 are used to tighten the stationary ring 102 and the rotating ring 103 together, so that the stationary ring 102 and the rotating ring 103 can fit tightly together. Stationary rings 102 are fixedly installed on both the fixed base 1 and the end cap 101. A pair of rotating rings 103 are installed between a pair of stationary rings 102. A rubber ring 104 is installed between a pair of rotating rings 103. An elastic component 110 is provided between a pair of rotating rings 103. The rotating rings 103 and the stationary rings 102 form a sealing surface through tight contact, preventing axial leakage of the medium. The rotating ring 103 rotates with the rotating shaft, while the stationary ring 102 remains stationary. Under the action of the elastic component 110, the two fit tightly together, forming a very small gap, thereby effectively preventing leakage of liquid or gas. The rubber ring 104 is used to prevent damage to the shaft when the clamping mechanism 2 is locked on the shaft. Each pair of moving rings 103 has a pair of corresponding slots 109. The slots 109 are used to hold the first fixing head 205 and the second fixing head 206, so that the moving rings 103 rotate when the clamping mechanism 2 rotates.

[0032] like Figures 1 to 5 As shown, multiple first fastening bolts 105 are installed between the fixed base 1 and the end cover 101, fixing the fixed base 1 and the end cover 101 together. Multiple second fastening bolts 106 are installed between the stationary ring 102 and both the fixed base 1 and the end cover 101, fixing a pair of stationary rings 102 to the fixed base 1 and the end cover 101 respectively. A sealing ring groove 107 is chiseled on the side of a pair of rotating rings 103 near the stationary rings 102, and a sealing ring 108 is installed in the sealing ring groove 107. By setting the sealing ring 108, the sealing performance between the stationary ring 102 and the rotating ring 103 is effectively improved.

[0033] like Figures 1 to 5 As shown, the elastic component 110 includes multiple mounting slots 111, which are carved into one of the rotating rings 103. An elastic body 112 is slidably disposed in each of the multiple mounting slots 111. The elastic body 112 is used to insert into the adapter slot 113 to ensure that the pair of rotating rings 103 rotate synchronously. On the other hand, it is used to push the pair of rotating rings 103 away from each other, so that the pair of rotating rings 103 and the pair of stationary rings 102 can fit tightly together to improve the sealing performance and increase the convenience of installation. Since the elastic body 112 is already set in the mounting slot 111, installing another rotating ring 103 only requires aligning the adapter slot 113 with the elastic body 112.

[0034] like Figures 1 to 5 As shown, another rotating ring 103 has an adapter groove 113 corresponding to the mounting groove 111. One end of the elastic body 112, which is located outside the mounting groove 111, is located in the adapter groove 113. By having one end of the elastic body 112 located outside the mounting groove 111 and located in the adapter groove 113, it is ensured that the pair of rotating rings 103 rotate synchronously. A groove is carved into the bottom of the elastic body 112. A spring 114 is installed between the top wall of the elastic body 112 and the bottom wall of the mounting groove 111. The elastic force of the spring 114 is used to push the elastic body 112 toward the adapter groove 113, thereby causing the pair of rotating rings 103 to adhere to the stationary ring 102 away from each other. A pair of sliding grooves 115 are carved in the mounting groove 111. A pair of limiting blocks 116 are fixed on the elastic body 112. The pair of limiting blocks 116 slide in the pair of sliding grooves 115. By sliding the limiting blocks 116 in the sliding grooves 115, the elastic body 112 is limited, preventing the elastic body 112 from being pushed out of the mounting groove 111 due to excessive elastic force of the spring 114.

[0035] like Figures 6 to 8As shown, the clamping mechanism 2 is mounted on the rubber ring 104. The clamping mechanism 2 includes a first clamping member 201 and a second clamping member 202, which are rotatably arranged relative to each other. By tightening the first clamping member 201 and the second clamping member 202 together, they are locked onto the main shaft. A first fixing head 205 and a second fixing head 206 are respectively fixed at the ends of the first clamping member 201 and the second clamping member 202. The first fixing head 205 and the second fixing head 206 are used to drive the first clamping member 201 and the second fixing head 206 to tighten together, and are also used to lock in the clamping groove 109, so that when the clamping mechanism 2 rotates, it drives the moving ring 103 to rotate.

[0036] like Figures 6 to 8 As shown, a first locking tooth 203 is fixed to the side of the first fixing head 205 away from the first clamp 201. One end of the first locking tooth 203 passes through the second fixing head 206 and is disposed on the second clamp 202. A second locking tooth 204 is fixed to the side of the second fixing head 206 away from the second clamp 202. One end of the second locking tooth 204 passes through the first fixing head 205 and is disposed on the first clamp 201. An elastic locking block 209 is fixed to both the first fixing head 205 and the second fixing head 206. The elastic locking block 209 is respectively locked onto the first locking tooth 203 and the second locking tooth 204. After the first fixing head 205 and the second fixing head 206 drive the first clamp 201 and the second clamp 202 to tighten each other, the elastic locking block 209 is locked onto the first locking tooth 203 and the second locking tooth 204, thereby preventing the first clamp 201 and the second clamp 202 from loosening. The first fixing head 205 and the second fixing head 206 are respectively engaged on the two side walls of the slot 109.

[0037] like Figures 6 to 8 As shown, a first groove 207 is chiseled on the first clamp 201, and one end of the second tooth 204 on the first clamp 201 slides in the first groove 207. A second groove 208 is chiseled on the second clamp 202, and one end of the first tooth 203 on the second clamp 202 slides in the second groove 208. By setting the first groove 207 and the second groove 208, when the first clamp 201 and the second clamp 202 are tightened, the first tooth 203 and the second tooth 204 are prevented from deviating. A control plate 210 is fixed on the elastic block 209. The control plate 210 is used to lift the elastic block 209 upwards to lift it off the first tooth 203 and the second tooth 204, thereby loosening the first clamp 201 and the second clamp 202. On the other hand, when the first fixing head 205 and the second fixing head 206 are locked at both ends of the slot 109, the control plate 210 abuts against the bottom edge of the slot 109 to prevent the elastic block 209 from lifting upwards, thereby preventing the first clamp 201 and the second clamp 202 from loosening.

[0038] In practical use, firstly, the rubber ring 104 is fitted onto the main shaft. Then, the clamping mechanism 2 is tightened onto the rubber ring 104. When tightening the clamping mechanism 2, the first fixing head 205 and the second fixing head 206 are pinched together. The first fixing head 205 and the second fixing head 206 respectively drive the first locking tooth 203 and the second locking tooth 204 to tighten. After tightening, the elastic locking block 209 is locked onto the first locking tooth 203 and the second locking tooth 204 to prevent the first clamping component 201 and the second clamping component 202 from loosening, allowing the pair of moving rings 103 to be installed onto the clamping mechanism 2. Align the slot 109 with the first fixing head 205 and the second fixing head 206, so that the first fixing head 205 and the second fixing head 206 are respectively located on the two side walls of the elastic block 209. Then, fix a pair of stationary rings 102 to the fixing seat 1 and the end cover 101 with the second fastening bolt 106. Then, install the fixing seat 1 and the end cover 101 onto the main shaft, so that the stationary ring 102 fits against one side of the moving ring 103. Fix the fixing seat 1 on the equipment. Then, fix the fixing seat 1 and the end cover 101 together with the first fastening bolt 105 to complete the assembly.
