Description

Pedal door mechanism

Technical Field

The utility model belongs to the lock field especially relates to a pedal lock mechanism that is used for downstairs steel construction stair to open door.

Background

The steel structure door that sets up at steel structure stair lower extreme need bend down and rotate the door handle when the switch, and this is not conform to human engineering. In addition, the structural door is usually used outdoors or in factories, and workers can carry articles and can generate potential safety hazards in the door opening and closing process. It is therefore desirable to develop a mechanism for opening a door without bending over.

Disclosure of Invention

For overcoming the not enough of prior art, the utility model aims at providing a pedal door mechanism can adopt pedal mode easily to open the door to make the door slowly close under the state of opening the door, can not quick resilience, can not have the potential safety hazard.

In order to achieve the above object, the utility model discloses a following technical scheme realizes:

the utility model provides a pedal door mechanism, including the door frame, a door, fold paper, integrative lock, the door frame is fixed subaerial, door and door frame are through folding paper articulated, be connected with integrative lock on the door, still include the pivot, the footboard, wire rope, the fixed pulley, the location box, door closing damper, pivot fixed connection is in the lower part of door, the footboard is articulated with the pivot, wire rope one end and footboard fixed connection, the spring bolt pivot piece fixed connection of fixed pulley and integrative lock is walked around to the other end, location box fixed connection is on the door, location box bottom and pivot are in the coplanar, be provided with wire rope in the location box, door closing damper installs at the door frame lateral part.

The fixed pulley is connected to the door.

The fixed pulley is arranged beside the integrated lock and is higher than the connecting position of the steel wire rope and the integrated lock.

The fixed pulley is connected with the door through a bracket.

The support is fixedly connected with the door, and mounting holes are arranged in rows on the support.

Compared with the prior art, the beneficial effects of the utility model are that:

the pedal door mechanism has simple and reasonable structure, adopts the pulleys, the steel wire rope and the pedals, can easily and simply open the door, and does not have potential safety hazard. Utilize the extreme position of location box limited footboard, avoid the footboard transition upset, simultaneously, can hide inside the location box wire rope, play protection wire rope's effect, in case take place wire rope and break up disconnected phenomenon, still can ensure user's safety. The setting of door closing damper can prevent that the back door that opens the door has the phenomenon of kick-backing fast, ensures personnel's safety, prolongs the life of door.

In the figure: 1-door frame, 2-door, 3-hinge, 4-rotating shaft, 5-pedal, 6-steel wire rope, 7-fixed pulley, 8-bolt rotating shaft piece, 9-integrated lock, 10-door closing damper 11-positioning box 12-support.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings, but it should be noted that the present invention is not limited to the following embodiments.

See fig. 1, fig. 2, a pedal door mechanism, including door frame 1, door 2, fold paper 3, integrative lock 9, door frame 1 is fixed subaerial, door 2 is articulated through folding paper 3 with door frame 1, be connected with integrative lock 9 on the door 2, still include pivot 4, footboard 5, wire rope 6, fixed pulley 7,

location box

11, 4 fixed connection in the lower part of door 2 of pivot, footboard 5 is articulated with

pivot

4, 6 one end of wire rope and footboard 5 fixed connection, the other end walks around fixed pulley 7 and the 8 fixed connection of the spring bolt pivot piece of integrative lock 9, location box 11 fixed connection is on door 2, location box 11 bottom is in the coplanar with pivot 4, be provided with wire rope 6 in the location box 11. The door closing damper 10 is installed at a side of the door frame 1.

Wherein the fixed pulley 7 is attached to the door 2 and is adjacent to the integral lock 9. The fixed pulley 7 is arranged beside the integrated lock 9 and is higher than the connecting position of the steel wire rope 6 and the integrated lock 9, so that more labor-saving door opening can be realized.

Referring to fig. 2 and 3, the fixed pulley 7 is connected with the door 2 through a support 12, the support 12 is fixedly connected with the door 2, and mounting holes are formed in the support 12 in rows and used for mounting the fixed pulley 7, conveniently adjusting the tightness of the steel wire rope 6 and facilitating maintenance and replacement of the fixed pulley 7 and the steel wire rope 6.

The utility model discloses it is simple reasonable, adopt pulley, wire rope 6, footboard 5, can relax simple and convenient opening the door to do not have the potential safety hazard.
