Abstract
The utility model discloses a worm wheel and worm type safety hook, which comprises a top plate, wherein the top plate is provided with a motor and a connecting plate; an output shaft of the motor is connected with a gear through a bearing; the gear is mutually engaged with gear teeth on the outer wall of a drum; gear teeth in the drum are engaged with a lead screw; the lead screw is connected with a safety hook through a connecting rod; and the safety hook is hinged with the connecting plate. Through the worm wheel and worm type safety hook, the defects in the prior art are overcome, and the cost and the energy are saved; and the worm wheel and worm type safety hook is safe and reliable.
Description
Technical field:
The utility model relates to the falling-proof safety device of mechanical stereo garage, is specifically related to a kind of Worm-gear type safety hook.
Background technology:
Mechanical Three-dimensional Garage many parts on falling-proof safety device are quoted electromagnet absorption traction and are driven safety hook and reset on the market at present, to reach the effect of safety hook.Yet the electromagnet that this mode is used needs long-term energising, and the time grown and will produce the demagnetization phenomenon, client vehicles is not had reliable safety assurance.
The utility model content:
The utility model provides a kind of Worm-gear type safety hook, has overcome deficiency of the prior art, practices thrift the cost and the energy, and is safe and reliable.
A kind of Worm-gear type safety hook wherein, comprises top board; On top board, be provided with motor and junction plate; The output shaft of said motor is connected through bearing with gear, and the gear teeth on gear and the cylinder outer wall are meshing with each other, the gear teeth in the cylinder and screw mandrel engagement; Screw mandrel is connected with safety door hook through connecting rod, safety door hook and junction plate hinge joint.
Further, said cylinder is provided with postive stop baffle.
Further, said top board is provided with travel switch.
The advantage of the utility model:
More the falling-proof safety device of Mechanical Three-dimensional Garage in the prior art adopts electromagnet absorption traction to drive safety hook and resets, to reach the effect of safety hook; Electromagnet that this mode is used needs long-term energising, and the time grown and will produce the demagnetization phenomenon, the utility model has overcome deficiency of the prior art; Adopt the driven by motor cylinder, cylinder drives screw mandrel, and then drives the mechanical motion mode of safety door hook motion; This mode need not to adopt electromagnet, thereby need not switch on for a long time, also the demagnetization phenomenon can not take place; Practice thrift the cost and the energy, and safe and reliable for a long time.
Other advantages, target and the characteristic of the utility model will be set forth in manual subsequently to a certain extent; And to a certain extent; Based on being conspicuous to those skilled in the art, perhaps can from the practice of the utility model, obtain instruction to investigating of hereinafter.The target of the utility model can realize through the structure that is particularly pointed out in following manual or the accompanying drawing and obtain with other advantages.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
The utility model comprises travel switch 1, motor 2, motor cabinet 3, connecting rod 4, junction plate 5, safety door hook 6, top board 7, bearing pin 8, cylinder 9, postive stop baffle 10, gear 12, motor output shaft 13 and screw mandrel 14; Travel switch is installed on the top board 7; Motor 2 is fixed on the top board 7 through motor cabinet 3, and motor output shaft 13 is connected through bearing 11 with gear 12, and the gear teeth on gear 12 and cylinder 9 outer walls are meshing with each other; On cylinder 9, be provided with two postive stop baffles 10; The gear teeth in the cylinder 9 and screw mandrel 14 engagements, screw mandrel 14 is connected with safety door hook 6 through connecting rod 4, and safety door hook 6 is through bearing pin 8 and junction plate 5 hinge joints.
The course of work of the utility model is:
Direct current generator 2 rotates through motor output shaft 13 driven gears 12; The rotation of cylinder 9 below the rotation of gear 12 drives, the rotation of cylinder 9 just promotes the rotation of screw mandrel 14 in the cylinder 9, and screw mandrel 14 is seesawed; Thereby promoted the swing of safety door hook 6, reached the purpose that safety door hook 6 is set.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Other modifications that those of ordinary skills make the technical scheme of the utility model perhaps are equal to replacement; Only otherwise break away from the spirit and the scope of the utility model technical scheme, all should be encompassed in the claim scope of the utility model.
