Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The present invention can also be implemented or applied through other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

Please refer to fig. 1-2. It should be understood that the structures, the proportions, the sizes, etc. shown in the drawings of the present specification are only used for matching with the contents disclosed in the specification, so as to be understood and read by those skilled in the art, and are not used for limiting the limit conditions which can be implemented by the present invention, so that the present invention does not have the essential technical meaning, and the modification of any structure, the change of the proportion relation or the adjustment of the size should still fall within the scope which can be covered by the technical contents disclosed in the present invention without affecting the function and the achievable purpose of the present invention.

Referring to fig. 1, the present invention provides a filter replacing tool, which can be used to solve the problem that the high efficiency filter of the existing air conditioning ventilation system is difficult to replace and disassemble. Specifically, the filter changing tool may include a connecting rod 100 and a clamping assembly 200, with the clamping assembly 200 being located at a distal end of the connecting rod 100. Thus, by providing the clamping assembly 200 at the end of the connecting rod 100, removal of the filter by the clamping assembly 200 is allowed. It should be noted that, for the filter, it may be allowed to be a high efficiency filter, a medium efficiency filter, and a low efficiency filter, but is not limited thereto, and it may be allowed to be determined according to actual needs.

Referring to fig. 1 and 2, in one embodiment, one end of the connecting rod 100 is connected to the clamping assembly 200, and a connection plate 300 is allowed to be connected to the other end of the connecting rod 100. One end of the connecting plate 300 is opened with a bevel 301, and the bevel 301 is located at a side close to the connecting rod 100. For the bevel opening 301, the angle between the bevel opening 301 and the connecting plate 300 is between 15 degrees and 30 degrees, for example, the size of the bevel opening 301 may be 15 degrees. However, the size of the included angle between the bevel opening 301 and the connection plate 300 can be determined according to actual requirements. Specifically, the filter replacing tool may allow the connection plate 300 at one end of the connection rod 100 to be clamped in a gap between a filter screen and a housing of the filter during the disassembly of the filter in a relatively narrow use environment. The filter changing tool may allow for a snap fit with the filter, thereby allowing for removal of the filter.

Referring to fig. 1 and 2, in one embodiment, the connecting rod 100 may be a length-adjustable structure to improve the applicability of the device in the actual use process. Specifically, the connecting rod 100 may comprise a sliding rod 101, a sliding sleeve 102 and a locking bolt 103, and the sliding rod 101 and the sliding sleeve 102 are slidably connected. Wherein, one end of the sliding rod 101 is fixedly connected with the connecting plate 300, and the clamping assembly 200 is located at the other end of the sliding sleeve 102. Thus, the length of the connecting rod 100 can be allowed to be adjusted by the relative sliding between the sliding bar 101 and the sliding sleeve 102. Further, a lock bolt 103 is connected to the sliding sleeve 102, and an end of the lock bolt 103 is connected to the sliding rod 101. Therefore, it is allowed to adjust the locking screw to make the sliding sleeve 102 and the sliding rod 101 in a relatively fixed state.

Referring to fig. 1 and 2, in one embodiment, the clamping assembly 200 may include a first link 210 and a second link 220. The first link 210 and the second link 220 are disposed at an included angle, and the included angle between the first link 210 and the second link 220 is adjustable. Specifically, the ends of the connecting rod 100 may allow for the fixed attachment of the bearings 110, for example, the bearings 110 may be attached to the sliding sleeve 102. Wherein, the outer ring of the bearing 110 is fixedly connected with the connecting rod 100, the inner ring of the bearing 110 is fixedly connected with the second connecting rod 220, and the first connecting rod 210 is fixedly connected with the outer ring of the bearing 110. Accordingly, rotation between the first link 210 and the second link 220 may be allowed by rotation of the inner ring and the outer ring of the bearing 110.

It should be noted that the end portions of the first link 210 and the second link 220 are fixedly connected with the connecting plates 300, respectively, and the connecting plates 300 on the first link 210 and the connecting plates 300 on the second link 220 are symmetrically arranged. The connection plate 300 on the first link 210 and the connection plate 300 on the second link 220 are also provided with a bevel 301, and the bevel 301 is located at one side of the connection rod 100. Therefore, the filter exchange tool may allow the connection plate 300 on the first link 210 and the connection plate 300 on the second link 220 to be caught in a gap between the filter cloth and the case of the filter during the disassembly of the filter. The filter changing tool may allow for a snap fit with the filter, thereby allowing for removal of the filter.

Referring to fig. 1 and 2, a spring 400 may be allowed to be connected between the first link 210 and the second link 220, and the spring 400 is used to drive the angle between the first link 210 and the second link 220 to have a tendency to expand. Therefore, the connection plate 300 on the first link 210 and the second link 220 can be tightly clamped in the filter by the spring 400.

It should be noted that, in order to improve the applicability of the device in the actual use process, a limiting rod 230 is further connected between the first connecting rod 210 and the second connecting rod 220, and a buckle is arranged at one end of the limiting rod 230. One end of the limiting rod 230 is pivotally connected to the first link 210, and a fastening end of the limiting rod 230 is allowed to be fastened to the second link 220. Therefore, the first link 210 and the second link 220 are within a predetermined range by the limiting rod 230, and the spring 400 is prevented from being damaged, thereby improving the using effect of the device.

Therefore, the utility model discloses thereby effectively overcome some practical problems among the prior art and had very high use value and use meaning.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.

Also, when numerical ranges are given in the examples, it is understood that both endpoints of each of the numerical ranges and any number between the endpoints are optional unless the utility model discloses otherwise. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs and are intended to describe the same, and all methods, apparatus and materials similar or equivalent to those described herein may be used in the practice of this invention.
