It may shorten the working life.
Summary of the invention
The purpose of the present invention is to provide a kind of unidirectional lifting driving devices, can overcome in the prior art above-mentioned scarce
It falls into.
A kind of unidirectional lifting driving device according to the present invention, comprising: support frame, the lifting being mounted on support frame as described above
Motor carries out hoistable platform and the installation of lifting movement by the screw shell that the screw rod coupled by lifting motor drives
Monodirectional locking component on support frame as described above, wherein the monodirectional locking component includes being respectively articulated on support frame as described above
Upper pendulum lock fixed pole and lower swing locking level at the left and right sides of the screw shell, the screw shell pass through on described
The through-hole of pendulum lock fixed pole and lower swing locking level, and the dextral platform portion of the upper pendulum lock fixed pole is on the top of upper top pressure spring
Pressure effect is lower so that the upper pendulum lock fixed pole tilts down, so that the upper locking in the through-hole of the upper pendulum lock fixed pole
The right side face bonding of tooth and the screw shell is to form the latching force for preventing the screw shell slide downward, the lower swing
The sinistral platform portion of locking level tilts down the lower swing locking level under the press effect of lower top pressure spring, to make
Lower locking teeth and the screw shell in the through-hole of the lower swing locking level left side face bonding with formed prevent it is described
The latching force of screw shell slide downward；The upper pendulum lock fixed pole and lower swing locking level can allow for lifting motor as a result,
The screw shell is lifted upwards and prevents moving downward for the screw shell.
According to the present invention, due to having used two hinged oscillating rods, screw shell can be locked from two sides, and
And the locking for moving downward is realized using the pressure of spring effect and downward tilt angle；Upward pendulum is utilized simultaneously
Power effect can be realized Self-unlocking to will not influence and move upwards.
Detailed description of the invention
Fig. 1 schematically illustrates the overall structure diagram of the device of the invention.
Specific embodiment
Below with reference to Fig. 1, embodiments of the present invention will be described.
Referring to Fig.1, a kind of unidirectional lifting driving device according to the embodiment, comprising: support frame 3 is mounted on the support
Lifting motor 94 on frame 3, the screw shell 92 driven and screw rod 93 coupled by lifting motor 94 carry out lifting fortune
Dynamic hoistable platform 91 and the monodirectional locking component being mounted on support frame as described above 3, wherein the monodirectional locking component includes
Upper pendulum lock fixed pole 81 and the lower swing lock being hingedly connected on support frame as described above 3 at the left and right sides of the screw shell 92
Fixed pole 61, the screw shell 92 pass through the through-hole of upper the pendulum lock fixed pole 81 and lower swing locking level 61, and the upper pendulum
The dextral platform portion 82 of dynamic locking level 81 makes the upper pendulum lock fixed pole 81 downwards under the press effect of upper top pressure spring 84
Inclination, so that the upper locking teeth 83 and the right side of the screw shell 92 in the through-hole of the upper pendulum lock fixed pole 81 connect
It closes to form the latching force for preventing 92 slide downward of screw shell, the sinistral platform portion 62 of the lower swing locking level 61 exists
The press effect of lower top pressure spring 64 is lower so that the lower swing locking level 61 tilts down, so that the lower swing locks
The left side face bonding of lower locking teeth 63 and the screw shell 92 in the through-hole of bar 61 prevents the screw shell 92 to be formed
The latching force of slide downward；The upper pendulum lock fixed pole 81 and lower swing locking level 61 can allow for lifting motor 94 will as a result,
The screw shell 92 is lifted upwards and prevents moving downward for the screw shell 92.
Valuably or illustratively, wherein the dextral platform portion 82 of the upper pendulum lock fixed pole 81 and the upper end of connecting rod 51
Hingedly, the sinistral platform portion 62 of the lower swing locking level 81 and the lower end of connecting rod 51 are hinged, under the sinistral platform portion 62
Side is engaged with lifting unlock drive rod 22, and the lifting unlock drive rod 22 is driven by unlock driving motor 21 and gone up and down；As a result,
The lifting unlock drive rod 22 moves upwards and can be pivoted up the upper pendulum lock fixed pole 81 and lower swing locking level 61
To unlock the screw shell 92 to allow moving downward for the screw shell 92.
Due to having used two hinged oscillating rods, screw shell can be locked from two sides, and utilize spring
Pressure effect and downward tilt angle and realize the locking for moving downward；It is acted on simultaneously using upward oscillatory forces,
Self-unlocking be can be realized to will not influence and move upwards.The device can effectively solve the problem that the above problem in the prior art.
In the above manner, those skilled in the art can be in spirit of the invention and main scope according to reality
It needs to make various changes with specific works mode.These change and modification is each fallen within the scope of protection of present invention.
Above-mentioned example of the invention is only exemplary, and should not be construed as limitation of the present invention.Protection scope of the present invention with
Subject to the attached claims.
