Description

Technical Field

[0001] This utility model relates to the field of filter bag technology, and more specifically, to a high-strength stretchable filter bag. Background Technology

[0002] In industrial dust removal and filtration systems, filter bags need to be length-adjusted according to different equipment and operating conditions. However, existing filter bags often lack a precise positioning control mechanism when adjusting their length and width. Operators find it difficult to quickly fix the filter bags in the required position. This adjustment process is not only time-consuming and labor-intensive, but also easily causes the filter bags to be unstable, affecting the filtration effect. At the same time, traditional fixing methods have poor reliability and are prone to displacement under equipment vibration and airflow impact, resulting in unstable working conditions of the filter bags.

[0003] In high-intensity, high-frequency industrial applications, filter bags need to be frequently adjusted in working length to adapt to different working conditions. Existing technologies cannot achieve precise fixing at any specified position, which greatly reduces the practicality and adaptability of filter bags. Especially when quick replacement or maintenance is required, traditional fixing methods are cumbersome, increasing maintenance time and labor intensity. These problems not only affect production efficiency but also increase equipment maintenance costs and operational risks. Utility Model Content

[0009] The present invention is further configured such that each of the multiple sets of sliders is provided with a movable groove, and each of the multiple sets of clamping plates is provided with a movable block on the outside. The movable block is slidably installed in the movable groove, and a push spring is provided between each of the multiple sets of sliders and the fixed sleeve. This design increases the flexibility and stability of the clamping plate, ensures the firm engagement of the locking block and the locking groove, and improves the stability and reliability of the filter bag body in the contracted state.

[0010] This invention is further configured such that each of the multiple sets of locking blocks is provided with an inclined surface. This design improves the engagement efficiency and reliability of the locking blocks and the locking slots, reduces friction during the locking and unlocking process, and ensures the smoothness and stability of the filter bag body during the expansion and contraction process.

[0011] The present invention is further configured such that multiple sets of slots are adapted to multiple sets of blocks.

[0012] The present invention is further configured such that the locking mechanism includes a locking block, a locking groove, and a locking sleeve. The locking block is provided in multiple sets and is slidably mounted on the sliding sleeve. The locking groove is provided in multiple sets and is distributed on the outer wall of the fixed sleeve.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a high-strength stretchable filter bag, which has the following beneficial effects:

[0017] 1. The telescopic mechanism, through the cooperation of the top ring, bottom ring, and movable ring, and the connection of multiple sets of sliding rods, achieves efficient telescopic movement of the filter bag body. When the filter bag body needs to be contracted, the top ring, bottom ring, and movable ring are tightened, and the sliding sleeve drives the push ring to push the bottom surface of the slider, causing the slider to slide along the inclined rod. The slider pushes the clamping plate to contact the sliding rod, so that the locking block is engaged in the locking groove, thereby achieving stable contraction of the filter bag body. This design not only improves the telescopic flexibility of the filter bag body, but also ensures the stability after contraction, avoiding accidental expansion of the filter bag body due to external pressure during use, and improving the safety and reliability of the filter bag body.

[0018] 2. The fixing mechanism, through the coordinated action of a fixing sleeve, diagonal rod, slider, spring, clamping plate, locking block, locking groove, push ring, sliding sleeve, and locking mechanism, ensures the secure fixation of the filter bag body in the contracted state. When the sliding sleeve slides, the push ring pushes the slider to slide along the diagonal rod, and the slider pushes the clamping plate to contact the sliding rod, causing the locking block to engage in the locking groove. The movable block on the top surface of the clamping plate slides in the movable groove. At the same time, the clamping plate and slider compress the spring, and the spring applies a pushing force to the clamping plate, ensuring that the locking block is securely engaged in the locking groove. The locking mechanism, through the cooperation of the locking block, locking groove, and locking sleeve, further fixes the sliding sleeve, preventing the sliding sleeve from moving under the action of external force, ensuring the stability and safety of the filter bag body in the contracted state. This design not only improves the fixing effect of the filter bag body, but also facilitates the rapid expansion and contraction of the filter bag body, improving the ease of use.

[0019] 3. The reinforced mechanism enhances the structural strength and stability of the filter bag body through the arrangement of multiple sets of reinforcing plates and compression springs. When the filter bag body is stretched, the top ring, bottom ring, and movable ring stretch the multiple sets of compression springs. The tensile force of the compression springs applies a certain tension to the multiple sets of reinforcing plates, forming a protective layer and improving the compressive strength and durability of the filter bag body. When the filter bag body shrinks, the contraction force of the multiple sets of compression springs pulls the multiple sets of reinforcing plates together for storage, preventing the reinforcing plates from scattering during the shrinkage process and ensuring the cleanliness and aesthetics of the filter bag body. This design not only improves the structural strength of the filter bag body but also extends its service life, enabling it to maintain good performance and stability under various working conditions.

[0029] Please see Figures 1-5A high-strength telescopic filter bag includes a filter bag body 1, on which a telescopic mechanism is provided. The telescopic mechanism includes a top ring 2, a bottom ring 3, a movable ring 4, a slide rod 5, and a fixing mechanism. The top ring 2 is installed at the top of the filter bag body 1, the bottom ring 3 is installed at the bottom of the filter bag body 1, the movable ring 4 is disposed on the outer wall of the filter bag body 1, and the slide rod 5 is provided with multiple sets connecting the top ring 2, the movable ring 4, and the bottom ring 3 respectively. The fixing mechanism includes a fixing sleeve 6, a diagonal rod 7, a slider 8, a spring 9, a clamping plate 10, a locking block 11, and a locking groove 12. The push ring 13, sliding sleeve 14 and locking mechanism are provided. The fixed sleeve 6 is installed on the movable ring 4. Multiple sets of inclined rods 7 are installed inside the fixed sleeve 6. The slider 8 slides on multiple sets of inclined rods 7. Multiple sets of springs 9 are installed on the slider 8. The clamping plate 10 is installed on the top of the spring 9. Multiple sets of locking blocks 11 are provided on the inner side of the clamping plate 10. Multiple sets of locking grooves 12 are distributed on the outer wall of the slide rod 5. The push ring 13 is located inside the fixed sleeve 6. The sliding sleeve 14 is installed on the outer side of the push ring 13 and is slidably connected to the fixed sleeve 6.

[0030] Each set of inclined rods 7 has a limiting strip 15 on its outer wall. The slider 8 is slidably connected to the limiting strip 15. The function of the limiting strip 15 is to ensure that the slider 8 will not deviate from the track when sliding on the inclined rod 7, and to maintain the stability and linear motion of the slider 8.

[0031] Each set of sliders 8 has a movable groove 16, and each set of clamping plates 10 has a movable block 17 on its outer side. The movable block 17 is slidably installed in the movable groove 16. Each set of sliders 8 is connected to the fixed sleeve 6 with a push spring 25. This design allows the clamping plate 10 to slide along the movable groove 16 on the slider 8, increasing the flexibility of the clamping plate 10. The push spring 25 applies a pushing force to the clamping plate 10 when the slider 8 slides, ensuring that the clamping plate 10 is in close contact with the slide rod 5, so that the locking block 11 can be firmly locked in the locking groove 12.

[0032] Each set of locking blocks 11 is provided with a slope. The slope design makes it easier for the locking blocks 11 to enter the slot 12 during the sliding process. At the same time, it can provide greater friction after locking to prevent the locking blocks 11 from sliding out of the slot 12.

[0033] Multiple card slots 12 are adapted to multiple card blocks 11. The design of the card slots 12 matches the shape and size of the card blocks 11, ensuring that the card blocks 11 can be firmly engaged in the card slots 12.

[0034] The locking mechanism includes a locking block 18, a locking groove 19, and a locking sleeve 20. The locking block 18 is provided with multiple sets that are slidably mounted on the sliding sleeve 14. The locking groove 19 is provided with multiple sets that are distributed on the outer wall of the fixed sleeve 6. The locking sleeve 20 is rotatably mounted on the outer wall of the sliding sleeve 14. When it is necessary to lock the sliding sleeve 14, the locking sleeve 20 is rotated, and the clearance groove 22 on the inner wall of the locking sleeve 20 pushes against the top of the locking block 18, so that the locking block 18 is engaged in the locking groove 19, thereby fixing the sliding sleeve 14. When it is necessary to unlock, the locking sleeve 20 is rotated, and the clearance groove 22 moves to the top of the locking block 18, releasing the restriction of the locking block 18 on the inner side of the locking sleeve 20. Under the action of the tension spring 21, the locking block 18 slides outward and disengages from the locking groove 19, thereby unlocking the sliding sleeve 14.

[0035] Each of the multiple sets of locking blocks 18 has a tension spring 21 installed at its top. The two ends of the multiple sets of tension springs 21 are respectively connected to the outer wall of the locking block 18 and the sliding sleeve 14. The inner wall of the locking sleeve 20 has a relief groove 22. There are multiple sets of relief grooves 22. The function of the tension spring 21 is to make the locking block 18 slide outward and disengage from the locking groove 19 when the locking sleeve 20 rotates, thereby unlocking the sliding sleeve 14. When the locking sleeve 20 rotates to the locked position, the relief groove 22 pushes against the top of the locking block 18, so that the locking block 18 is engaged in the locking groove 19, thereby fixing the sliding sleeve 14.

[0036] In this embodiment, when the filter bag body 1 needs to be contracted, the top ring 2, bottom ring 3, and movable ring 4 are tightened. Then, the sliding sleeve 14 drives the push ring 13 to abut and push the bottom surface of the slider 8, causing multiple sets of sliders 8 to slide along the inclined rod 7. The sliders 8 push the clamping plate 10 to contact the sliding rod 5, causing multiple sets of locking blocks 11 to engage in the locking groove 12. The movable block 17 set on the top surface of the clamping plate 10 slides in the movable groove 16. At the same time, the clamping plate 10 and the slider 8 compress multiple sets of springs 9, and the springs 9 apply a pushing force to the clamping plate 10. Finally, the sliding sleeve 14 is locked and limited by the locking mechanism. The locking sleeve 20 is rotated so that its inner wall abuts and pushes the top of multiple sets of locking blocks 18, causing multiple sets of locking blocks 18 to engage in the locking groove 19, so that the sliding sleeve If the 14 cannot move, the movable ring 4 can be fixed to complete the shrinkage of the filter bag body 1. When it is necessary to stretch the filter bag body 1, the locking mechanism is released from the limit of the sliding sleeve 14. The locking sleeve 20 is rotated to drive the multiple sets of relief grooves 22 to rotate. When the multiple sets of relief grooves 22 move to the top of the multiple sets of locking blocks 18, the restriction of the locking block 18 on the inner side of the locking sleeve 20 is released. The tension spring 21 elastically resets and pulls the locking block 18 to slide outward, so that the locking block 18 is disengaged from the locking groove 19, and the locking of the locking groove 19 is released, so that the sliding sleeve 14 is released from the restriction. The push spring pushes the slider 8 to slide along the inclined block, so that the locking block 11 on the inner wall of the clamping plate 10 is disengaged from the locking groove 12. Then the fixing sleeve 6 is separated from the sliding rod 5, and then the top ring 2 or the bottom ring 3 is pulled to stretch the filter bag body 1.

[0037] Please see Figures 1-2As one implementation of the reinforcement mechanism: a reinforcement mechanism is provided on the outside of the filter bag body 1. The reinforcement mechanism includes a reinforcement plate 23 and a compression spring 24. Multiple sets of reinforcement plates 23 are distributed on the outside of the filter bag body 1, and multiple sets of compression springs 24 are respectively connected to multiple sets of reinforcement plates 23.

[0038] More specifically, when the filter bag body 1 is stretched, the top ring 2, bottom ring 3 and movable ring 4 stretch multiple sets of compression springs 24 respectively. Under the stretching of multiple sets of tension springs, a certain tension is applied to multiple sets of reinforcing plates 23 to form a protective layer. When the filter bag body 1 shrinks, the multiple sets of compression springs 24 shrink and pull the multiple sets of reinforcing plates 23 to gather and store them.

[0039] In summary, during the use or operation of the overall equipment: when it is necessary to shrink the filter bag body 1, the top ring 2, bottom ring 3, and movable ring 4 are tightened. Then, the sliding sleeve 14 drives the push ring 13 to abut and push the bottom surface of the slider 8, causing multiple sets of sliders 8 to slide along the inclined rod 7. The slider 8 pushes the clamping plate 10 to contact the sliding rod 5, causing multiple sets of locking blocks 11 to engage in the locking groove 12. The movable block 17 set on the top surface of the clamping plate 10 slides in the movable groove 16. At the same time, the clamping plate 10 and the slider 8 compress multiple sets of springs 9, and the springs 9 apply a pushing force to the clamping plate 10. Finally, the locking mechanism locks and limits the sliding sleeve 14. Rotating the locking sleeve 20 causes its inner wall to abut and push the top of multiple sets of locking blocks 18, causing multiple sets of locking blocks 18 to engage in the locking groove 19, so that... When the sliding sleeve 14 cannot move, the movable ring 4 can be fixed, and the filter bag body 1 can be contracted. When it is necessary to stretch the filter bag body 1, the locking mechanism is released from the limit of the sliding sleeve 14. The locking sleeve 20 is rotated to drive the multiple sets of relief grooves 22 to rotate. When the multiple sets of relief grooves 22 move to the top of the multiple sets of locking blocks 18, the restriction of the locking block 18 on the inner side of the locking sleeve 20 is released. The tension spring 21 elastically resets and pulls the locking block 18 to slide outward, so that the locking block 18 is disengaged from the locking groove 19, and the locking of the locking groove 19 is released, so that the sliding sleeve 14 is released from the restriction. The push spring pushes the slider 8 to slide along the inclined block, so that the locking block 11 on the inner wall of the clamping plate 10 is disengaged from the locking groove 12. Then the fixing sleeve 6 is separated from the sliding rod 5, and then the top ring 2 or the bottom ring 3 is pulled to stretch the filter bag body 1.

[0040] When the filter bag body 1 is stretched, the top ring 2, bottom ring 3 and movable ring 4 stretch multiple sets of compression springs 24 respectively. Under the stretching of multiple sets of tension springs, a certain tension is applied to multiple sets of reinforcing plates 23 to form a protective layer. When the filter bag body 1 shrinks, the multiple sets of compression springs 24 shrink and pull the multiple sets of reinforcing plates 23 to gather and store them.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
