Further: the outside that is positioned at the two ends of the first slotted hole on the first locating part is respectively arranged with the first locating part locating slot, two crotch portions of the openend of the first bent other hook locate by the first locating part locating slot respectively, the outside that is positioned at the two ends of the 4th slotted hole on the second locating part is respectively arranged with the second locating part locating slot, and two crotch portions of the openend of the second bent other hook locate by the second locating part locating slot respectively.
Further: the closed end of the second bent other hook is connected with iron chains.
Further: the closed end of the first bent other hook is connected with CAP NUTS.
The utility model also provides the cloth bag structure that adopts above-mentioned hanging mechanism, comprises cloth bag, and CAP NUTS is connected with cloth bag.
The beneficial effects of the utility model are: utilize the position-limiting action of locating part, make not contact mutually between bent other hook and spring, thereby avoided rubbing between the two.By locating part, can guarantee that two other hooks of song are mutually vertical, and then can guarantee the center line of spring and the center line of cloth bag consistent, can reduce the fault rate of cloth bag.Hanging mechanism of the present utility model is simple in structure, low cost of manufacture.This erecting by overhang has very strong limit effect for having the higher back-blowing bag-type dusting facility of pressure, can improve the stability of cloth bag operation, reduces the fault rate of cloth bag, is having blast furnace gas back-blowing bag-type dusting industry to have good application prospect.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of hanging mechanism of the present utility model;
Fig. 2 is the schematic diagram of locating part;
In figure, be labeled as: bent other hook 4, the first slotted hole 5, the second slotted holes 6 of the bent other hook 3, the first of the first locating part 1, the second locating part 2, the second, iron chains 7, spring 8, CAP NUTS 9, the first locating part locating slots 10.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As depicted in figs. 1 and 2, hanging mechanism of the present utility model, comprise the bent other hook 4 of spring 8, first and the second bent other hook 3, the first bent other hook 4 comprises openend and closed end, the openend of the first bent other hook 4 comprises two crotch portions separated from one another, the second bent other hook 3 comprises openend and closed end, and the openend of the second bent other hook 3 comprises two crotch portions separated from one another, and the two ends of spring 8 are respectively arranged with the first locating part 1 and the second locating part 2; The first locating part 1 has cross through hole, the cross through hole of the first locating part comprises the first orthogonal slotted hole 5 and the second slotted hole 6, the openend of the first bent other hook 4 by the first slotted hole 5, passed and with the two ends clamping of the first slotted hole 5, the closed end of the second bent other hook 3 is passed by the second slotted hole 6; The second locating part 2 has cross through hole, the cross through hole of the second locating part comprises the 3rd slotted hole and the 4th slotted hole, the closed end of the first bent other hook 4 is passed by the 3rd slotted hole, the openend of the second bent other hook 3 by the 4th slotted hole, passed and with the two ends clamping of the 4th slotted hole; The first bent other hook 4 is by leaving gap between the first locating part 1 and the second locating part 2 maintenances and spring, and the second bent other hook 3 is by leaving gap between the first locating part 1 and the second locating part 2 maintenances and spring; By the first locating part 1 and the second locating part 2, make the first bent other hook 4 and the second bent other hook 3 keep vertical relation.In order effectively to keep, between bent other hook and spring, leave gap, can be when arranging, the length of above-mentioned each slotted hole is all less than to the internal diameter of spring, because the length of each slotted hole is all less than the internal diameter of spring, bent other hook is only contacted with locating part, cannot with spring contact, make can keep certain interval between two other hooks of song and spring, in use, bent other hook can not rub with spring.And that cross through hole can guarantee between two other hooks of song is mutually vertical, can effectively guarantee that like this spring is in deformation process, the center line of its center line and cloth bag is consistent.When arranging, the madial wall of each slotted hole is as far as possible little with the gap between the other hook of corresponding song, for example, can be less than 0.5mm, such good limit effect.
