Compared with the prior art, the technical scheme of the utility model possess following beneficial effect:

the utility model provides a telescopic bag cage mechanism of slide bar through slider and slide, just can let two slide bars relative slip to change the distance between the support ring that these two slide bars are connected. Therefore, the bag cage can be stretched and contracted, and is convenient to transport and store.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.

The scheme takes a six-rib six-section bag cage as an example, and fig. 1 is a schematic structural view of the bag cage after contraction, wherein the bag cage comprises seven support rings 103 and six sliding rod groups 102, and each sliding rod group comprises six sliding rods 101. Fig. 2 is a side view of the bag cage, and the curvature of the outside circle of the support ring 103 is equal to the curvature of the inside arc of the slide bar group 102, so as to increase the contact strength between the slide bars 101 and the support ring 103. The section of the sliding rod 101 is formed by cutting concentric circular rings according to a certain central angle, the section is 8 degrees in the figure, the outer surface of the bag cage is ensured to be still round, the smoothness degree of the contact surface of the bag cage and the filter bag is increased, and the filter bag is not easy to scratch.

In this embodiment, two adjacent slide bars 101 in the slide bar group 102 are connected in a sliding manner, so that the two adjacent slide bars 101 can slide relatively, and the distance between two adjacent support rings 103 can be changed, so that the bag cage can be contracted, and the bag cage is convenient to transport and store. Fig. 2 is a front view of the bag cage after contraction, and as shown in the figure, the support ring 103 is welded on the top of the slide bar 101, wherein the bottom of the slide bar 101 of the first section of the bag cage also contains the support ring 103. The sliding rods 101 in the sliding rod group 102 are staggered by a certain distance along the axial direction, so that two ends of a first sliding rod 101 in the sliding rod group 102 are respectively connected outside one supporting ring 103, and each of the rest sliding rods 102 is welded with and only welded with one supporting ring 103 in the supporting ring group;

fig. 3 is a schematic structural view of the support ring 103, which is shown as being rectangular in cross section along the axial direction.

Fig. 4 is a schematic structural diagram of the slide rods 101, two adjacent slide rods 101 are respectively provided with a T-shaped slide way 302 and a slide block 303 on opposite sides, in order to prevent the slide block 303 from being jammed, the slide block 303 is circular, the contact area between the slide way 302 and the slide block 303 is reduced, and a gap is left between the slide block 303 and the slide way 302 in a matching manner. The top of the slide way is provided with a limiting structure 301 for preventing the slide block 303 from separating from the slide way 302.

Figure 5 shows the movement of the bag cage mechanism. As shown in the figure, two adjacent sliding rods 101 are connected by a sliding block 303 and a sliding way 302 mechanism, and when the sliding rods 101 extend to the maximum position, the sliding block 303 is prevented from being separated from the sliding way 302 by a limiting structure 301.

The sliding rod telescopic bag cage mechanism has the advantages that the longitudinal ribs of the bag cage adopt the sliding rod and sliding block structures, so that the length of the bag cage can be reduced to one section, the length of the bag cage is reduced, and the bag cage mechanism is convenient to transport and store.

The support ring 103 and the slide bar 101 are both made of 2205 stainless steel, so that the overall strength of the bag cage mechanism is ensured, the curvature of the inner side arc of the slide bar 101 is equal to that of the outer side arc of the slide bar 101, the contact surface is ensured to be inosculated, and the welding strength is improved. The circular sliding block 303 can reduce the contact area with the slide way, and a gap is reserved between the sliding block 303 and the slide way 302 in a matching manner, so that the smooth degree of the movement of the mechanism is increased.

The outer surface of the cage is round, so that the smoothness of the contact surface of the bag cage and the filter bag is increased, and the filter bag is not easy to scratch.

The above description is only an exemplary embodiment of the present invention, and the scope of the present invention should not be limited accordingly. The equivalent changes and modifications made according to the patent scope and the content of the specification of the present invention should still fall within the scope covered by the present invention.
