Abstract
The utility model discloses an universal chain link, it includes two relative chain sheaths, has coaxial chain sheath hole on two chain sheaths, the axis perpendicular to chain sheath plane in chain sheath hole, its characterized in that: the upper half part and the lower half part of the chain sheath are intersected planes, a pair of coaxial chain sheath holes are respectively arranged, the axes of the two chain sheath holes are straight lines with different surfaces, and the two pairs of chain sheath holes are respectively connected with other chain links. The utility model discloses can select the transmission direction wantonly as required.
Description
Technical field
The utility model belongs to the chain technical field, relates in particular to a kind of Hook's joint that changes the chain direction.
Background technique
At some by the field of chain as the transmission medium of power, particularly in the energy-storage module or other similar structures of the spring operating mechanism of high-pressure vacuum breaker, sometimes need to change the transmission direction of chain, and this can't accomplish with general drive chain according to the relative position between energy storage motor and spring structure.What use in the spring operating mechanism of now commercially available high-pressure vacuum breaker all is general chain, as the ZW36-126 type single break vacuum circuit breaker of being developed by Beijing Beikai Electrical Co., Ltd..
Summary of the invention
To be solved in the utility model is the technical problem that can't change direction in the chain transmission, and a kind of Hook's joint that can select transmission direction arbitrarily is provided
The technical solution adopted in the utility model is such: Hook's joint, comprise two relative chain sheaths, on two chain sheaths coaxial chain sheath hole is arranged, the axis normal in chain sheath hole is in chain sheath plane, it is characterized in that: upper half part of chain sheath and lower half portion plane for intersecting, a pair of coaxial chain sheath hole is respectively arranged, and two chain sheath axially bored lines are different surface beeline, and two pairs of chain sheath holes link to each other with other chain link respectively.
Upper half part and lower half portion that preferred scheme is the chain sheath are the plane that intersects vertically, and two chain sheath axially bored lines are mutually perpendicular different surface beeline.
In this scheme, the size of angle between can dividing by the upper and lower half that changes the chain sheath, the i.e. relative position of two chain sheath axially bored lines, change the transmission direction of chain, so, the relative position between spring and the energy storage motor just can be set arbitrarily, and according to different relative positions, determine the relative position of two chain sheath axially bored lines, produce the different Hook's joint of steering angle.
This Hook's joint is specially adapted to energy-storage module and other similar structures of high-pressure vacuum breaker spring operating mechanism.
Description of drawings
Fig. 1 is the use working drawing of the utility model in the energy-storage module of high-pressure vacuum breaker spring operating mechanism.
Fig. 2 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, in the energy-storage module of high-pressure vacuum breaker spring operating mechanism, use Hook's joint disclosed in the utility model, drive camming (1) by energy storage motor and be rotated counterclockwise, realize energy storage by chain (4,7) compression spring assembly (9).Upper saw pulley (2,3,6,8) plays the guide and limit effect, because the existence of Hook's joint (5), the transmission direction of chain (4,7) has been changed.
As shown in Figure 2, the chain sheath (14) of Hook's joint (5) comprises upper half part (10,13) and lower half portion (15,16), the axis normal in chain sheath hole (11,12) is in chain sheath (10,13) plane, the axis normal in chain sheath hole (17) is in chain sheath (15,16) plane, chain sheath (10,13) and chain sheath (15,16) parallel separately and vertical respectively, two chain sheath axially bored lines are also orthogonal.
Claims (2)
1. Hook's joint, comprise two relative chain sheaths, on two chain sheaths coaxial chain sheath hole is arranged, the axis normal in chain sheath hole is in chain sheath plane, it is characterized in that: upper half part of chain sheath and lower half portion plane for intersecting, a pair of coaxial chain sheath hole is respectively arranged, and two chain sheath axially bored lines are different surface beeline, and two pairs of chain sheath holes link to each other with other chain link respectively.
2. Hook's joint as claimed in claim 1 is characterized in that: upper half part of chain sheath and lower half portion are the plane that intersects vertically, and two chain sheath axially bored lines are mutually perpendicular different surface beeline.
