Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning filters, in particular to a novel filter pressing mechanism. Background Art

[0002] Air conditioning has very strict requirements on sealing when filtering. Generally, it is necessary to stick a sealing strip between the bag filter and the filter frame. In order to maintain good sealing, the bag filter needs to be firmly pressed against the filter frame to ensure sealing. Currently, the bag filter pressing device that is commonly used is a special-shaped card made of spring steel, which is matched with the convex holes and buckles stamped on the filter frame to achieve the purpose of pressing the air bag filter.

[0003] However, there are some disadvantages in using it: 1. When the diameter of spring steel is large, the elastic force is large and it is difficult to operate, and the special-shaped card is not easy to use. When the diameter of special-shaped steel is small, it cannot compress the filter bag well; 2. The performance of the special-shaped card will decrease after a period of use, which will affect the sealing; 3. The special-shaped card is not easy to remove and replace. Utility Model Content

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-3 As shown, a new filter clamping mechanism includes a filter body 1, a clamping assembly 2 is arranged at the front end of the filter body 1, the clamping assembly 2 includes a main pressure block 21 installed at the front end of the filter body 1, a secondary pressure block 22 is installed on the side of the front end of the filter body 1 close to the main pressure block 21, a connecting hole 23 is opened at one end of the main pressure block 21, a docking hole 24 is opened at one end of the secondary pressure block 22, a threaded head 25 is movably connected to the inner side of the connecting hole 23, one end of the threaded head 25 is fixedly connected to a connecting rod 26, an outer side of the threaded head 25 is threadedly connected to an internal threaded ring 27 close to the connecting hole 23, and a handle 28 is fixedly connected to the upper end of the main pressure block 21.

[0020] In this embodiment, a rubber sleeve 29 is sleeved on the outer side of the handle 28, and the main material of the rubber sleeve 29 is rubber. The main pressure block 21 and the auxiliary pressure block 22 are both semicircular eccentric wheels. The main pressure block 21 and the auxiliary pressure block 22 correspond to each other, and the connecting hole 23 corresponds to the docking hole 24. The diameter of the connecting rod 26 is larger than the diameter of the threaded head 25. There are two groups of threaded heads 25 and internal threaded rings 27. The other group of threaded heads 25 is located on the inner side of the docking hole 24. The two groups of internal threaded rings 27 are in contact with the main pressure block 21 and the auxiliary pressure block 22 respectively.

[0021] Specifically, the main pressure block 21 and the auxiliary pressure block 22 are clamped on the frame of the filter body 1, and then the handle 28 is gripped. Since the handle 28 and the worker's hand are separated by the rubber sleeve 29, the rubber sleeve 29 improves the comfort of the worker holding the handle 28. Then, the handle 28 is pressed to make the handle 28 drive the main pressure block 21 and the auxiliary pressure block 22 to rotate, so that the main pressure block 21 and the auxiliary pressure block 22 squeeze the filter body 1 in the shape of the eccentric wheel, thereby achieving the purpose of compacting the filter body 1. By installing the main pressure block 21 and the auxiliary pressure block 22 in the frame of the filter body 1, and then pressing the handle 28 to make the main pressure block 21 and the auxiliary pressure block 22 rotate, the purpose of facilitating the main pressure block 21 and the auxiliary pressure block 22 to squeeze the filter body 1 in the shape of the eccentric wheel can be achieved, thereby facilitating the compacting of the filter body 1 and facilitating the worker's operation. Moreover, the eccentric shape of the main pressure block 21 and the auxiliary pressure block 22 avoids the compacting performance of the compacting assembly 2 from being reduced.

[0022] In this embodiment, the lower end of the filter body 1 is fixedly connected to a support base 3, and the shape of the support base 3 is rectangular.

[0023] Specifically, the support base 3 can facilitate the support of the filter body 1 .

[0024] Working principle:

[0025] When in use, first insert the two sets of threaded heads 25 into the inner sides of the connecting hole 23 and the docking hole 24 respectively, and adjust the main pressure block 21 and the auxiliary pressure block 22 to the corresponding state, and then screw the two sets of internal threaded rings 27 onto the outer sides of the two sets of threaded heads 25 respectively, so as to fix the main pressure block 21 and the auxiliary pressure block 22 together through the connecting rod 26, and then clamp the main pressure block 21 and the auxiliary pressure block 22 on the frame of the filter body 1, and then hold the handle 28 tightly. Since the handle 28 and the worker's hand are separated by the rubber sleeve 29, the rubber sleeve 29 improves the comfort of the worker holding the handle 28, and then press the handle 28 to make the handle 28 drive the main pressure block 21 and the auxiliary pressure block 22 rotates, so that the main pressure block 21 and the auxiliary pressure block 22 squeeze the filter body 1 in the shape of the eccentric wheel, thereby compacting the filter body 1. By installing the main pressure block 21 and the auxiliary pressure block 22 in the frame of the filter body 1 and then pressing the handle 28 to rotate the main pressure block 21 and the auxiliary pressure block 22, the purpose of squeezing the filter body 1 in the shape of the eccentric wheel can be achieved, thereby compacting the filter body 1 and facilitating the operation of workers. In addition, the eccentric shape of the main pressure block 21 and the auxiliary pressure block 22 can avoid the compression performance of the compression assembly 2 from decreasing, and facilitate the disassembly of the compression assembly 2.

[0026] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
