Summary of the invention
The purpose of this utility model provide a kind of component processing simply, the three rod-type constant-force spring hangers that easily assemble, need not to lead, overcome the deficiencies in the prior art.
Three rod-type constant-force spring hangers of the present utility model, comprise be positioned at the top by two parallel support side plate, the support that the front cover of the top board of support side plate top and support side plate below is formed, two parallel rotor plates are arranged in the support and be rotationally connected by main shaft and support side plate, being positioned at a side of main shaft and the upper end of load bolt on the rotor plate is rotationally connected, the opposite side that is positioned at main shaft on two rotor plates has connecting plate, the adjustment bolt is arranged on this connecting plate, adjust bolt between two rotor plates, adjusting the inner end of bolt and the upper end of arm-tie is rotationally connected, spring is arranged below front cover, there is pressing plate the lower end of spring, and arm-tie passes between the center hole of front cover and lower end and the pressing plate and is rotationally connected.
Three rod-type constant-force spring hangers of the present utility model, wherein said arm-tie is two, described adjustment bolt clip is between two arm-tie upper end portions, two slotted holes are arranged on pressing plate, the lower end of described two arm-ties is stretched out also downwards from two slotted holes respectively, and end machining has pin-and-hole, bearing pin penetrates in this pin-and-hole, between bearing pin and the pressing plate for fixedlying connected.
Three rod-type constant-force spring hangers of the present utility model, when operation, swing mechanism is if any a certain amount of swing, adjust bolt and drive the arm-tie action, spring is compressed, this moment, arm-tie had certain radial and axial displacement in the center hole of front cover, and the rotation of several angle is arranged with respect to pressing plate, need not guide element leads, reduce guide element of the prior art, saved the process time and the installation process of component, time saving and energy saving, greatly reduce cost, effectively prevented the generation of suspension bracket stuck phenomenon.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is that B shown in Figure 1 is to schematic representation;
Fig. 3 is the schematic top plan view of pressing plate.
Embodiment
As shown in Figure 1: this suspension bracket top is support, and this support comprises two support side plate that are parallel to each other 22, is welded with top board 1 in the top of two support side plate 22, is processed with mounting hole on the top board 1, is used for fixing this suspension bracket.Bottom in support side plate 22 is welded with front cover 6.Support forms frame structure.
Be connected with swing mechanism on the support, concrete structure is as follows: two rotor plates that are parallel to each other 3 are arranged in the support inboard, be rotationally connected mutually by main shaft 18 between rotor plate 3 and the support side plate 22.Be fixed with displacement indication bearing pin 2 in the outside of each rotor plate 3, displacement indication bearing pin 2 just is positioned at the curve bath 21 on the support side plate 22, guarantee that rotor plate 3 can relatively rotate several angle with respect to support side plate 22, when rotor plate 3 rotates with respect to support side plate 22 along main shaft 18, can indicate bearing pin 2 and curve bath 21 to carry out the spacing of displacement indication and rotor plate 3 rotation limit positions by displacement.
A side that is positioned at main shaft 18 on rotor plate 3 is rotationally connected by the upper end of coupling shaft 20 with load bolt 19.Be that load bolt 19 can rotate with respect to rotor plate 3 along coupling shaft 20.Be connected with degree of tightness nut 17 at the lower end of load bolt 19 screw thread and be used to connect the lifted weight thing.
