Therefore, they cannot be understood as limitations on the present invention.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The following is combined with Figure 1-Figure 6 The utility model is further described.

[0027] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: a foldable dust bag cage.

[0028] The specific technical scheme includes a fixed bag cage section 1 and a folding bag cage section 2. The fixed bag cage section 1 includes an end plate 101, an outer keel rod 102 and a connecting ring plate 103. The outer keel rod 102 is evenly welded to the end plate 101 and the connecting ring plate 103, which are welded in sequence. The folding bag cage section 2 includes a fixed ring plate 201 and an inner keel rod 202. One end of the inner keel rod 202 is evenly welded to the inner side of the fixed ring plate 201, and the other end of the inner keel rod 202 is located in the connecting ring plate 103 and is arranged on the inner side of the outer keel rod 102. A guide ring 3 is welded on the outer side of one end of the inner keel rod 202. The guide ring 3 is sleeved on the outer side of the outer keel rod 102. By moving the guide ring 3 along the outer keel rod 102, the bag cage can be controlled to be unfolded as a whole or the fixed bag cage section 1 and the folding bag cage section 2 can be overlapped together.

[0029] Reference Figure 4 and Figure 5 As shown, two of the relatively arranged guide rings 3 are welded with positioning pieces 4 on their outer sides, and a positioning groove 5 corresponding to the positioning piece 4 is opened on one side of the connecting ring plate 103. The folding bag cage section 2 can be fully unfolded after the positioning piece 4 is moved into the positioning groove 5.

[0030] Reference Figure 5 and Figure 6 As shown, protrusions 6 are welded on both sides of the connecting ring plate 103, and the protrusions 6 are located outside the positioning groove 5. A receiving groove 7 is provided on one side of the protrusion 6. A through hole 8 communicating with the receiving groove 7 is provided between the positioning groove 5 and the outer wall of the connecting ring plate 103. A fixing structure 9 is provided in the positioning groove 5 and the through hole 8. The folding bag cage section 2 and the fixed bag cage section 1 can be fixedly connected through the fixing structure 9, thereby ensuring good stability during use, and at the same time being convenient for being able to be quickly folded together again when disassembled and not in use.

[0031] The fixing structure 9 includes a fixing block 901, a control rod 902, a control spring 903 and a control head 904. A fixing hole 10 is provided on the positioning plate 4 and is located on one side of the through hole 8. One end of the fixing block 901 is clamped in the through hole 8 and the other end is clamped in the fixing hole 10. The fixing plate can be fixed by the part of the fixing block 901 clamped in the fixing hole 10. A notch is provided between the outer wall of the accommodating groove 7 and the protrusion 6. The control head 904 is arranged on the outside of the notch. The control rod 902 is welded between the fixing block 901 and the control head 904 and is clamped in the notch. The position of the control rod 902 and the fixing block 901 can be conveniently adjusted through the control head 904, thereby conveniently releasing the fixing effect.

[0032] A pulling piece 11 is welded on one side of the control head 904 . The diameter of the pulling piece 11 is larger than the diameter of the control head 904 , so the control head 904 can be easily pulled to move.

[0033] The compression length of the control spring 903 is greater than the depth of the fixing hole 10 , thereby providing sufficient movement space for the fixing block 901 .

[0034] In order for those skilled in the art to fully understand the technical solution, this application makes the following overall summary:

[0035] When the utility model is in use, the folded state is as follows Figure 2As shown, when it needs to be unfolded for use, the folding bag cage section 2 is pulled, the guide ring 3 can move along the outer keel frame, and then the pulling piece 11 and the control head 904 are pulled outward, so that the control rod 902 can drive the fixed block 901 to move into the through groove 8 and the accommodating groove 7, and the positioning piece 4 moves into the positioning groove 5 and then releases the pulling piece 11. The fixed block 901 can bounce into the fixing hole 10 under the elastic force of the control spring 903, thereby fixing the folding bag cage section 2, and then it can be used.

[0036] The standard parts used in the utility model can be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art.
