The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.

Please refer to Fig.1 to Fig.4, a kind of auto-folder bag cage, including expansion bracket 10, sliding block 30, ring support 20, annulus branch Support 50, stent bar 40, electric pushrod 60 and driving motor (not shown)；Horizontal arrangement and face between two ring supports 20 Set, i.e., two ring supports are completely overlapped in the projection of horizontal plane.

Expansion bracket 10 is connected to form by multiple X-type telescopic units 11 ending, and each expansion bracket 10 is slided by sliding block 30 It is arranged between two neighboring ring support 20.X-type telescopic unit 11 includes two panels metal strip cross-articulation, the hinge joint It is located at for X-type telescopic unit intersection point 11a, fulcrum 11a at the center of two panels metal strip.The X-type of the outermost end of expansion bracket 10 is stretched Four endpoints of contracting unit 11 connect one piece of sliding block 30 respectively, and both each expansion bracket 10 was connected to two annulars by four pieces of sliding blocks 30 Between stent 20.

Expansion bracket 10 is set around ring support 20 to surround to form an accommodating space with ring support 20；Electric pushrod 60 Relative to the axially symmetric distribution of ring support 20, ensure that ring support stress is symmetrical, when elongating or shortening, 20 energy of ring support It is always maintained at level.Preferable ring support 20 is regular hexagon, and ring support 20 is formed with expansion bracket 10 and electric pushrod 60 Accommodating space be in positive six ribs right cylinder.It is high that ring support 20 uses hexagonal structure that whole storage unit can be allowed to possess comparison Stability, 6 stents can allow arch brace frame 50 to possess more supporting point, and overall structure is more stablized.In storage unit 100 need to stack or when multiple tilings, and each side of regular hexagon can be completely superposed, and when transport saves sky very much Between.

The quantity of electric pushrod can be more, all connected at each angle of hexagon, and thrust and support force intensity all will more Greatly, but the important and production cost of corresponding bag cage will improve, the power that the quantity of electric pushrod is born according to actual needs Spend to select.

The surrounding of ring holder 50 is by the fixed setting of stent bar 20 with expansion bracket 10, connecting same annular brace The stent bar 40 of frame 50 is connected on the intersection point 11a of the X-type telescopic unit 11 of sustained height.It is connected to intersection point 11a On, one is conveniently to allow ring holder 50 to follow the stretching motion of expansion bracket 10 to raise or decline, on the other hand, allow friendship Point 11a load-bearing annular supporting racks, are most stability, ensure that 4 endpoint uniform forces of X-type telescopic unit 11.

Bag cage, which needs to install filter bag, realizes dedusting function, and the bag cage of the utility model is that filter bag is installed on several rings Shape supporting rack is surrounded in the hollow circuit cylinder formed.Bag cage includes bottom cover 70, bag cage from opening to 70 direction of bottom cover on The 3rd arch brace frame 50 and the bottom cover on be equipped with lock, for filter bag to be fixedly mounted, prevent filter bag in bag cage Shrink shrivelled.

The distance between two neighboring arch brace frame is h, when expansion bracket 10 reaches capacity development length, 18cm≤h ≤20cm.H is too small, and the setting of arch brace frame is excessively intensive, causes bag cage quality to increase, and the installation of bag cage is sometimes furred ceiling and hangs Empty, the excessive stability that certainly will influence bag cage installation of quality；Quality is excessive, and cost of transportation and manufacture cost can all increase accordingly Greatly.When h is excessive, during injection tube outlet air directly over bag cage, since ring holder 50 is spaced much, filter bag is easy by wind-force Excessively spread towards surrounding, and pull filter bag installing port, filter bag is caused to pull open the accidental destructions such as scuffing, reduces the practicality of filter bag Service life.

The preferred h=20cm of the utility model, had not only met the protection to filter bag, but also to be unlikely to ring holder 50 excessively close Collection, reduces the overall weight of bag cage.Arch brace frame internal diameter is r, 15cm≤r≤16cm；Existing filter bag is coordinated to use, it is optimal Choosing for 15cm, be slightly less than the diameter of filter bag, when ensureing ventilation, filter bag can be close to circular support frame 50, reduce filter bag Stress.

The initial length of electric pushrod 60 is L1, and the extensible length of electric pushrod 60 is L2, each X-type telescopic unit 11 Compression height be h1, each X-type telescopic unit 11 can wicking height be h2, the X-type telescopic unit 11 of each expansion bracket Quantity is n, meets L1≤h1*n, L2 >=h2*n, and L1+L2 >=(h1+h2) * n.The initial length of electric pushrod 60 is less than or equal to Height under the most compressed state of expansion bracket, it is ensured that when compressing transport, each bag cage occupies transport space minimum.

L1+L2 be electric pushrod 60 to greatest extent height, (h1+h2) * n be expansion bracket maximum height, electric pushrod 60 maximum height is more than the maximum height of expansion bracket 10；If the maximum that the maximum height of electric pushrod 60 is less than expansion bracket 10 is high Degree, then in use, expansion bracket 10 does not just reach maximum elongation value, at this time, the setting of X-type telescopic unit 11 is excessive, can subtract Small number.

Most preferably, L1+L2=(h1+h2) * n, X telescopic units 11 and electric pushrod 60 be in the slight error installed, Select electric pushrod 60 to be slightly larger than the height of expansion bracket 10, ensure that expansion bracket 10 can most be played the height utilization of limit, avoid X The excessive setting of type telescopic unit 11, causes to waste.

Existing long bag cage, it is impossible to compress, occupied space is excessive during transport；The bag cage of the utility model, when not in use, pressure It is reduced to minimum constructive height；Same transport space, the freight volume of foldable bag cage are five to seven times of traditional long bag cage, are subtracted significantly Small cost of transportation.

When in use, the bag cage that compression is transported is powered the bag cage of the utility model, driving motor driving electric pushrod Elongation, the length elongation of whole bag cage close motor to suitable length；Limitation of the bag cage from air-purifying chamber height is folded, is needed How many height are needed, are elongated to more big heights.

The mounting means of existing bag cage is complicated, and when needing with changing bag cage, first to remove the injection tube of top；The bag of this case After cage is installed on injection tube, first injection tube is fixedly mounted, then filter bag is fixed and is placed in bag cage, by the ring holder of bag cage It is fixedly connected on the erecting device of injection tube, the air outlet of injection tube, which is stretched into first arch brace frame of bag cage, to be engaged surely Gu first arch brace frame 50 gives injection tube support force, it is ensured that the outlet air position of injection tube and bag cage are coaxial.Other are implemented In mode, injection tube is first installed, filter bag is placed in bag cage, and opening is fixed on the 3rd arch brace frame；Bag cage is aligned The air outlet of injection tube, startup motor will extend first arch brace frame 50 and engage with the air outlet of injection tube in bag cage, really Protect injection tube and be more than 25cm apart from the distance of filter bag, in case wind-force is excessive, it is excessive to filter bag impact force.When replacing bag cage, only Need to be by bag cage height reduction, replacement can be removed by being retracted to certain altitude, without removing injection tube.

In the selection of filter bag, using filter bag length slightly larger than the 3rd arch brace frame of bag cage to bottom cover 70 away from From again when bag cage extends to greatest extent, bag cage energy spread apart, which is unlikely to pull tension, to be caused to damage；If bag cage does not have to extend to To greatest extent, filter bag is heaved in bag cage by the effect of wind-force to the gap expansion between arch brace frame 50, limited In bag cage length, increase filter area, improve filter effect.

The bag cage of the utility model is compressed to minimum value in transit, by each bag cage, then put into successively it is cellular, The design of stretching structure causes the long bag cage volume of bag cage volume ratio tradition itself to greatly reduce, and regular hexagonal prism is shaped such that each Each side of bag cage can closely place in gapless fitting, and in limited transport space, the transport quantity of regular hexagonal prism will Much larger than circle.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this The spirit of utility model and any modification, equivalent substitution, improvement and etc. within principle, done, should be included in the utility model Within the scope of protection.
