Abstract

An electric door belongs to the field of doors. One end of a main flexible outer barrel is permanently connected with a beam; the other end is connected with a driving flexible inner cylinder inside the main flexible outer barrel through thread. An output shaft of a first reductor is connected with one end of a long worm. One end of a first worm wheel which is meshed with and is driven by or drives the long worm is connected with a transmission shaft through keys; the other end is matched with a supporting shaft in a sliding way. The transmission shaft is connected with the driving flexible inner cylinder. The supporting shaft is connected with a transverse cylinder at the bottom, and is fixed with pin rolls. A second reductor is permanently arranged in a flute in ground. An output shaft of the second reductor is permanently connected with a second worm. The second worm is on the same level with the ground. A second worm wheel meshed with and driving the second worm is axially fixed on one end of the transverse cylinder at the bottom. One end of a driven expansion sleeve is connected with the beam; the other end is permanently connected with the transverse cylinder at the bottom. Both ends of the transverse cylinder at the bottom are connected to a bed. When the utility model is folded, the utility model can be on the same level with the ground, accordingly, takes up no space. After the utility model is unfolded, the height of the door can be adjusted at discretion. The utility model is applicable for various fields.

Description

Electric door

Technical field

The utility model relates to a kind of door, specifically a kind of scalable, folding electric door.

Background technology

Most popular in the market electric door is the electric expansion gate, and its weak point is the cost height, and used tubing is many, can not regulate height, and the occupation of land space is big.

Summary of the invention

Goal of the invention of the present utility model is the defective at prior art, provides space, a kind of battlefield little, low, collapsible, the telescopic electric door of cost of manufacture.

Realize the foregoing invention purpose by the following technical solutions: a kind of electric door, comprise base, motor, the reductor that is connected with motor and the ground groove that is used with electric door, its structural feature is, initiatively outer telescopic tube one end is fixedlyed connected with crossbeam, and the other end is threaded with the inner core that initiatively stretches that is positioned at it; The output shaft of first reductor is fixedlyed connected with the end of long worm screw, be connected with key with power transmission shaft with first worm gear, one end of long worm engaging transmission, the other end and bolster are slidingly matched, and this power transmission shaft is connected with the inner core that initiatively stretches, and this bolster is connected with the bottom transverse tube and locatees with bearing pin; Second reductor is fixedly mounted in the underground groove, is fixedly connected with second worm screw on its output shaft, and second worm screw and ground are positioned on the same horizontal plane, is axially fixed in an end of bottom transverse tube with second worm gear of the second worm engaging transmission; One end of passive extension sleeve is fixedlyed connected with crossbeam, and the other end is fixedlyed connected with the bottom transverse tube, and the two ends of bottom transverse tube are connected on the base.

Owing to adopted technique scheme, to compare with existing electric door, its remarkable advantage is, can be on the same horizontal plane with ground when it is packed up, therefore taking up room is zero, can regulate height of V window opening arbitrarily after opening, and adapts to various and use.In addition, the utility model design science is reasonable, and is simple in structure, the outward appearance novelty, and used tubing is few, and cost of manufacture is low.

Fig. 2 is first worm gear and power transmission shaft, bolster syndeton schematic diagram.

Fig. 3 is the state diagram of retracting cylinder when not stretching out.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

The utility model by second worm screw 1, second worm gear 2, lifting motor 3, initiatively outer telescopic tube 4, initiatively stretch inner core 5, power transmission shaft 6, first worm gear 7, grow worm screw 8, bottom transverse tube 9, passive extension sleeve 10, crossbeam 11, bolster 12, bearing pin 13, first reductor 14, second reductor 15, electric rotating machine 16, base 17, key 18, groove 19 is formed.

Referring to accompanying drawing 1, accompanying drawing 2, lifting motor 3 is fixedlyed connected with first reductor 14, and the output shaft of first reductor 14 is fixedlyed connected with the end of long worm screw 8, long worm screw 8 and first worm gear, 7 engaged transmission.First worm gear, 7 one ends are connected with power transmission shaft 6 usefulness keys 18, and the other end and bolster 12 are slidingly matched.Power transmission shaft 6 is connected with the inner core 5 that initiatively stretches, and bolster 12 passes bottom transverse tube 9 usefulness bearing pins 13 location.Bottom transverse tube 9 is a square structure, and lifting motor 3, first reductor 14, long worm screw 8 and first worm gear 7 are positioned at bottom transverse tube 9.Retracting cylinder is made up of two active retracting cylinders and the moving retracting cylinder of two velamens, initiatively retracting cylinder is divided into urceolus and inner core, initiatively outer telescopic tube 4 is the same axis of symmetry with the inner core 5 that initiatively stretch, and this active outer telescopic tube 4 is a double-decker, wherein in drum outer wall be provided with external screw thread.The inwall of inner core 5 of initiatively stretching is provided with the internal thread that is used with described external screw thread.Initiatively outer telescopic tube 4 one ends are fixedlyed connected with crossbeam 11, and the other end flexibly connects with the inner core 5 usefulness screw threads that initiatively stretch.Two passive extension sleeve 10 1 ends are fixedlyed connected with crossbeam 11 respectively, and the other end is fixedlyed connected with bottom transverse tube 9.Bottom transverse tube 9 can axially revolve and turn 90 degrees.

Electric rotating machine 16 is fixedlyed connected with second reductor 15, is fixedly connected with second worm screw, 1, the second worm gear 2 and the 1 engaged transmission work of second worm screw on the output shaft of second reductor 15, and second worm gear 2 is axially fixed in bottom transverse tube 9 ends.Second worm gear 2 is movably connected on the base 17 together with the two ends of bottom transverse tube 9.Second reductor 15 is fixed on the installing plate, and installing plate is fixed in the groove 19 of ground below 20, and second worm screw 1 and ground 20 are on same horizontal plane.

Referring to Fig. 3, ground 20 has the groove 19 that is used with electric door (dropping to minimum dimension), and after electric door is put down and ground 20 is on same horizontal plane.

Use step:

Upright be an angle of 90 degrees when electric door is in, when retracting cylinder rises, put down electric door and at first start lifting motor 3 and fall retracting cylinder, control electric rotating machine 16 then, make to revolve to turn 90 degrees to fall in the groove 19 to lowest order with ground.
