Dynamic securing rod and the through hole of lower swing securing rod, and the dextral platform portion of described upper pendulum lock fixed pole is in the top of upper top pressure spring pressure
Make described upper pendulum lock fixed pole downward-sloping under effect, so that the upper locking teeth in the through hole of described upper pendulum lock fixed pole
Engaging with the right flank of described screw shell to form the latching force preventing described screw shell slide downward, described lower swing is locked
The sinistral platform portion of fixed pole makes described lower swing securing rod downward-sloping under the top pressure effect of lower top pressure spring, so that
Lower locking teeth in the through hole of described lower swing securing rod engages with the left surface of described screw shell and prevents described spiral shell to be formed
The latching force of stricture of vagina sleeve slide downward；Thus, described upper pendulum lock fixed pole and lower swing securing rod can allow for lifting motor general
The upwards lifting of described screw shell and stop moving downward of described screw shell；Fixedly mount on the end face of support frame as described above top
Having crashproof cushion pad, described crashproof cushion pad touches with support frame as described above when moving downward in order to avoid described hoistable platform
Hit, thus improve use safety guarantee.
According to the present invention, owing to employing two hinged swing arms, screw shell can be locked by it from both sides, and
And utilize the pressure effect of spring and downward angle of inclination and realize the locking for moving downward；Utilize pendulum upwards simultaneously
Dynamic action, it is possible to realize Self-unlocking thus do not interfere with and move upward.
Accompanying drawing explanation
Fig. 1 schematically illustrates the overall structure schematic diagram of assembly of the invention.
Detailed description of the invention
Below in conjunction with Fig. 1, embodiments of the present invention are illustrated.
With reference to Fig. 1, according to the one of embodiment unidirectional lifting equipment, including: bracing frame 3, it is arranged on support frame as described above 3
Lifting motor 94, the screw shell 92 that driven by the screw rod 93 that coupled by lifting motor 94 carry out the liter of lifting campaign

The upper pendulum lock fixed pole 81 at the left and right sides of described screw shell 92 and lower swing securing rod it is hingedly connected on bracing frame 3
61, described screw shell 92 is through described upper pendulum lock fixed pole 81 and the through hole of lower swing securing rod 61, and described upper pendulum lock
The dextral platform portion 82 of fixed pole 81 makes pendulum lock fixed pole 81 on described downward-sloping under the top pressure effect of upper top pressure spring 84,
So that the upper locking teeth 83 in the through hole of described upper pendulum lock fixed pole 81 engage with the right flank of described screw shell 92 with
Forming the latching force preventing described screw shell 92 slide downward, the sinistral platform portion 62 of described lower swing securing rod 61 is at Xia Ding
Make described lower swing securing rod 61 downward-sloping under the top pressure effect of pressing spring 64, so that described lower swing securing rod 61
Through hole in lower locking teeth 63 engage with the left surface of described screw shell 92 with formed prevent described screw shell 92 downward
The latching force slided；Thus, described upper pendulum lock fixed pole 81 and lower swing securing rod 61 can allow for lifting motor 94 by described
Screw shell 92 upwards lifting and stop moving downward of described screw shell 92；Fixing peace on the end face of support frame as described above 3 top
Equipped with crashproof cushion pad 31, described crashproof cushion pad 31 is in order to avoid described hoistable platform 91 when moving downward and described support
Frame 3 collides, thus improves use safety guarantee.
Valuably or exemplarily, wherein, near the dextral platform portion 82 of described upper pendulum lock fixed pole 81 with connecting rod 51
Upper end thereof, hinged with the lower end of connecting rod 51 near the sinistral platform portion 62 of described lower swing securing rod 81, described sinistral platform
The downside in portion 62 unlocks drive rod 22 with lifting and engages, and described lifting unlocks drive rod 22 and driven motor 21 to drive by unblock and rise
Fall；Thus, described lifting unlocks drive rod 22 move upward can be by described upper pendulum lock fixed pole 81 and lower swing securing rod 61
It is pivoted up unlocking to allow moving downward of described screw shell 92 to described screw shell 92.
Owing to employing two hinged swing arms, screw shell can be locked from both sides, and utilize spring by it
Pressure effect and downward angle of inclination and realize the locking for moving downward；Utilize oscillatory forces effect upwards simultaneously,
It is capable of Self-unlocking thus does not interferes with and move upward.This device can effectively solve the problem that the problems referred to above of the prior art.
By with upper type, those skilled in the art can the present invention spirit and main scope according to reality
Need and specific works pattern makes various change.Within these changes and modification each fall within the scope of protection of present invention.
The above-mentioned example of the present invention is merely exemplary, should not be construed as limitation of the present invention.Protection scope of the present invention with
