Description

Technical Field

[0001] This utility model relates to the field of bag cage technology, and in particular to a foldable bag cage. Background Technology

[0002] In industrial production processes, a large amount of dust-laden waste gas is generated. In order to protect the environment and ensure the normal operation of production equipment, these waste gases need to be treated for dust removal. Bag filter technology has been widely used among many dust removal technologies due to its advantages such as high efficiency, stability and reliability. As one of the key components of a bag filter, the bag cage's function is to support the filter bag, so that the filter bag maintains a certain shape and size when filtering dust-laden gas, ensuring the smooth progress of the filtration process.

[0003] Traditional filter cages are typically a single, large unit that takes up a lot of space during transport, making them inconvenient to move and increasing transportation costs. Furthermore, in practical applications, different industrial scenarios require filter bags of various sizes, but traditional filter cages have a fixed height and cannot be flexibly adjusted to accommodate different sizes of filter bags, thus limiting their application range.

[0004] In response to the technical problems of bag cages being inconvenient to transport and unable to be flexibly adjusted to accommodate filter bags of different sizes, thus limiting their applicability, this application proposes a foldable bag cage. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of bag cages, such as inconvenience in transportation and inability to be flexibly adjusted to accommodate filter bags of different sizes, thus limiting their applicability. A foldable bag cage is proposed to address these issues. By folding the connecting rods on the upper and lower sides, the folded bag cage is made easier to transport, reducing transportation costs. Furthermore, by pressing the locking block, the block retracts into the first lifting rod, allowing the first lifting rod to move along the outer wall of the first support rod, thereby adjusting the overall height of the bag cage to accommodate filter bags of different sizes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a foldable bag cage, comprising a first connecting ring, with first support rods fixedly connected to the left and right sides of the top of the first connecting ring, a first lifting rod slidably connected to the inner wall of the first support rod, the first lifting rod being connected to the first support rod via a snap-fit ​​assembly, a second connecting ring fixedly connected to the top of the first lifting rod, connecting seats fixedly connected to the bottom of the first connecting ring and the top of the second connecting ring on all four sides, a rotating shaft rotatably connected to the inner wall of each connecting seat, a connecting rod fixedly connected to the outer wall of the rotating shaft, the other end of the connecting rod being connected to a third connecting ring via bolts, and a limit assembly provided at the front end of the rotating shaft.

[0007] The snap-fit ​​assembly includes a snap-fit ​​block that is slidably connected to the inner wall of the first lifting rod. The front end of the first support rod has multiple snap-fit ​​slots, and the outer wall of the snap-fit ​​block matches the shape of the inner wall of the snap-fit ​​slot.

[0008] Furthermore, a first spring is fixedly connected to the rear end of the locking block, and the rear end of the first spring is fixedly connected to the rear end of the inner wall of the first lifting rod.

[0009] Furthermore, the limiting component includes a rod slidably connected to the inner wall of the connecting seat, a first locking tooth fixedly connected to the rear end of the rod, the outer wall of the first locking tooth slidably connected to the inner wall of the connecting seat, and a second locking tooth fixedly connected to the front end of the rotating shaft, wherein the first locking tooth engages with the second locking tooth.

[0010] Furthermore, a second spring is sleeved on the outer wall of the insertion rod, the front end of the second spring is fixedly connected to the inner wall of the connecting seat, and the rear end of the second spring is fixedly connected to the front end of the first locking tooth.

[0011] Furthermore, a pull handle is fixedly connected to the front end of the insertion rod to control the movement of the first locking tooth.

[0012] Furthermore, a second support rod is fixedly connected to both the front and rear sides of the top end of the first connecting ring, and a second lifting rod is slidably connected to the inner wall of each of the second support rods. The top end of the second lifting rod is fixedly connected to the bottom end of the second connecting ring.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by removing the third connecting rings on the upper and lower sides, and then pulling the pull rod to move the first locking tooth forward, the restriction on the second locking tooth is removed, allowing the connecting rod to rotate on the inner wall of the connecting seat, thereby folding the connecting rods on the upper and lower sides, making the folded bag cage convenient for transportation and reducing transportation costs.

[0015] 2. In this utility model, by pressing the locking block, the locking block is retracted into the first lifting rod, so that the first lifting rod can move on the outer wall of the first support rod, thereby adjusting the overall height of the bag cage to accommodate filter bags of different sizes.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-3 This utility model provides an embodiment of a foldable bag cage, including a first connecting ring 1. First support rods 2 are fixedly connected to the left and right sides of the top of the first connecting ring 1. A first lifting rod 3 is slidably connected to the inner wall of the first support rod 2. (Refer to...) Figure 4 The inner wall of the first lifting rod 3 is slidably connected to a locking block 4. The front end of the first support rod 2 has multiple locking slots 5. The outer wall of the locking block 4 matches the inner wall of the locking slot 5. The rear end of the locking block 4 is fixedly connected to a first spring 6. The rear end of the first spring 6 is fixedly connected to the rear end of the inner wall of the first lifting rod 3. The top end of the first lifting rod 3 is fixedly connected to a second connecting ring 7. The front and rear sides of the top end of the first connecting ring 1 are fixedly connected to second support rods 17. The inner walls of the second support rods 17 are slidably connected to second lifting rods 18. The top end of the second lifting rods 18 is fixedly connected to the bottom end of the second connecting ring 7.

[0027] Specifically, the second support rods 17 and the second lifting rods 18 on the front and rear sides will move along with the movement of the first support rods 2 and the first lifting rods 3 on the left and right sides. During transportation, the first lifting rods 3 can be retracted into the innermost part of the first support rods 2, thereby reducing the length of the bag cage and facilitating transportation.

[0028] Reference Figures 5-7 The bottom of the first connecting ring 1 and the top of the second connecting ring 7 are fixedly connected to four sides of the connecting seat 8. The inner wall of the connecting seat 8 is rotatably connected to the rotating shaft 9. The outer wall of the rotating shaft 9 is fixedly connected to the connecting rod 10. The other end of the connecting rod 10 is connected to the third connecting ring 11 by bolts. The inner wall of the connecting seat 8 is slidably connected to the insert rod 13. The rear end of the insert rod 13 is fixedly connected to the first locking tooth 14. The outer wall of the first locking tooth 14 is slidably connected to the inner wall of the connecting seat 8. The front end of the rotating shaft 9 is fixedly connected to the second locking tooth 15. The first locking tooth 14 and the second locking tooth 15 are engaged. The outer wall of the insert rod 13 is fitted with a second spring 16. The front end of the second spring 16 is fixedly connected to the inner wall of the connecting seat 8. The rear end of the second spring 16 is fixedly connected to the front end of the first locking tooth 14. The front end of the insert rod 13 is fixedly connected to the pull handle 12 for controlling the movement of the first locking tooth 14.

[0029] Specifically, after removing the third connecting ring 11 and rotating the connecting rod 10 to a horizontal position, the third connecting ring 11 can be placed horizontally and connected to the connecting rod 10 on one side by bolts, thereby preventing the third connecting ring 11 from being lost during transportation. When in use, it is necessary to pull the insert rod 13 to separate the first locking tooth 14 from the second locking tooth 15, then rotate all the connecting rods 10 to a vertical position, and then install the third connecting ring 11 on the connecting rod 10. Then, place the filter bag inside the bag cage so that the bag cage supports the filter bag.

[0030] Working principle: During transportation, first remove the bolts on the third connecting ring 11, so that the third connecting ring 11 no longer restricts the connecting rod 10. Then, pull the handle 12 at the front end of the connecting seat 8. The handle 12 drives the insert rod 13 forward, and the insert rod 13 drives the first locking tooth 14 forward, so that the first locking tooth 14 disengages from the second locking tooth 15. At the same time, the first locking tooth 14 will compress the second spring 16. Then, rotate the connecting rod 10, so that the connecting rod 10 rotates within the connecting seat 8. Rotate the connecting rod 10 to a horizontal position, and then release the handle 12. The second spring 16 rebounds the first locking tooth 14, so that the first locking tooth 15... The first locking tooth 14 engages with the second locking tooth 15, thereby restricting the rotation of the rotating shaft 9, preventing the horizontal connecting rod 10 from wobbling, and ensuring that the overall length of the folded bag cage is not too long, with a relatively reasonable volume, making it more convenient for transportation. During use, the locking block 4 can be pressed to retract into the first lifting rod 3 and compress the first spring 6. Then, the position of the first lifting rod 3 can be adjusted, and the locking block 4 can be released. The first spring 6 will move the rebound locking block 4 outward, allowing the locking block 4 to enter the locking groove 5 and fix the first lifting rod 3. This allows the overall length of the bag cage to be changed, thus adapting to filter bags of different lengths and expanding the applicability of the bag cage.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
