Abstract
The utility model provides an electric screw bar elevating gear for burglary -resisting door, including frame, drive machine, screw rod, lift bracket, nut, nut permanent seat, upper bearing fixing base. The drive machine device is on the frame to be connected with screw rod one end through transmission, the other end of screw rod passes through the bearing and is connected with the upper bearing fixing base. Frame and upper bearing fixing base are fixed respectively on the skeleton of door leaf. The cover is equipped with the nut, fixedly connected with nut permanent seat on the nut, nut permanent seat and lift bracket fixed connection, lift bracket and movable part fixed connection on the screw rod. Screw rod, nut can be for the bull structures. The nut also can be for the plastic nut. Compared with the prior art, the utility model discloses an electric screw bar elevating gear for burglary -resisting door owing to adopt the electric screw bar structure, does not need the manual work manual, and easy operation is convenient.
Description
Technical field
The utility model relates to a kind of lifting gear, particularly relates to a kind of Motorized lift device for security door.
Background technology
Security door has both antitheft and security performance.The metal anti-theft door that the security door of current use has the real abdomen door of the individual layer not possessing ventilation and lighting function, door is provided with anti-theft grid structure and screen window, exterior wing have safety grid and ventilation window and double-layer door that interior wing is real abdomen door.The shortcoming of the real abdomen door of individual layer does not have ventilation and lighting function, though the metal anti-theft door being provided with anti-theft grid structure and screen window has ventilation and daylighting function, do not have sound insulation and sealing effectiveness, and the shortcoming of double-layer door takes up room comparatively large and cost is higher.
Have design to propose Combined theft-proof door, door leaf is divided into inside and outside door-plate, arranges gravity vent at inside and outside door-plate, arranges liftable movable part, as baffle plate, glass etc. between inside and outside door-plate.Thus must lifting gear be set.When lifting gear adopts manual, operate harder.
Utility model content
The utility model is overcome above-mentioned deficiency, provides a kind of security door electronic screw lifting device, easy to operate.
The utility model is realized by following technical scheme:
The electronic screw lifting device of a kind of security door, comprises support, driving motor, screw rod, shears, nut, nut holder, upper bearing (metal) holder.
Driving motor device on support, and is connected with screw rod one end by transmission device, and the other end of screw rod is connected with upper bearing (metal) holder by bearing.Support and upper bearing (metal) holder are separately fixed on the skeleton of door leaf.
Screw rod is set with nut, nut is fixedly connected with nut holder, nut holder is fixedly connected with shears, and shears is fixedly connected with movable part.
Improve further as the utility model, described screw rod is multiple-threaded screw, and nut is bull nut.
Improve further as the utility model, described nut is plastic nut.
Compared with prior art, the electronic screw lifting device of security door of the present utility model, owing to adopting electric screw structure, does not need manually, simple to operation.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model movable part lifting position front schematic view.
Accompanying drawing 2 is the utility model movable part lifting position side schematic view.
Accompanying drawing 3 is the utility model movable part down position side schematic view.
In figure: 1-support, 2-driving motor, 3-draws aluminum frame, 4-multiple-threaded screw, 5-shears, 6-plastic nut, 7-nut holder, 8-upper bearing (metal) holder, 9-movable part.
Detailed description of the invention
Below in conjunction with accompanying drawing, the electronic screw lifting device of this practical a kind of Anti-theft door is described further.
The electronic screw lifting device of a kind of security door, comprises support 1, driving motor 2, draws aluminum frame 3, multiple-threaded screw 4, shears 5, plastic nut 6, nut holder 7, upper bearing (metal) holder 8.
Driving motor 2 device on support 1, and is connected with multiple-threaded screw 4 one end by transmission device, and the other end of multiple-threaded screw 4 is connected with upper bearing (metal) holder 8 by bearing.Support 1 and upper bearing (metal) holder 8 are separately fixed on the skeleton of door leaf.
Multiple-threaded screw 4 is set with plastic nut 6, plastic nut 6 is fixedly connected with nut holder 7, nut holder 7 is fixedly connected with shears 5, and shears 5 is fixedly connected with movable part.
Drive plastic nut 6 to move up and down when multiple-threaded screw 4 rotates, plastic nut 6 drives movable part 9 to move up and down by shears 5 simultaneously, and the motion of movable part 9 is led by the ways be arranged on door leaf.
A kind of security door of the utility model is as follows by the electronic screw lifting device course of work:
When movable part 9 needs to rise, control the direction of rotation of driving motor 2, drive plastic nut 6 to move upward when multiple-threaded screw 4 rotates, plastic nut 6 moves upward under driving the ways guiding of movable part 9 on door leaf by shears 5 simultaneously.Movable part 9 stops driving motor 2 behind in-position.
When movable part 9 needs to decline, control the direction of rotation of driving motor 2, drive plastic nut 6 to move downward when multiple-threaded screw 4 rotates, plastic nut 6 moves downward under driving the ways guiding of movable part 9 on door leaf by shears 5 simultaneously.Movable part 9 stops driving motor 2 behind in-position.
