Abstract
The utility model relates to a cam -type intermittent control structure for revolving door, including interior carousel, outer carousel, the cam, the ejector pin, locating pin and spring, the outer carousel of the coaxial suit of interior carousel outer fringe, including a carousel middle part coaxial arrangement cam, the system has two bellied cams of mirror symmetry on this cam, every arch on this cam realizes the unidirectional rotating cooperation with an ejector pin respectively, the system has the top on the position of every ejector pin and protruding contact, the one end of every ejector pin is passed through the locating pin and is fixed with interior carousel, the other end passes through the hinge with the one end of a spring and is connected, the other end of spring is fixed through another locating pin and interior carousel. The utility model provides a cam -type intermittent control structure for revolving door's cam and the corotation that the ejector pin passes through the axis of rotation and reversal realize the forward motion, and the structure of reverse mismatch realizes the intermittent control of revolving door from this through electric motor rotating shaft corotation and reversal, and simple structure is reasonable, and easily installation is used and is hanged down with cost of maintenance.
Description
Technical field
This utility model belongs to revolving door field, particularly a kind of Cam intermittent control structure for revolving door.
Background technology
Revolving door is using and in maintenance process, rotate and stopping is respectively adopted respective driving structure and stops into structure, need to run two groups of control panels just can complete when controlling, certain waste is all also existed for energy and space, and part revolving door is in order to save the energy and space at present, by microprocessor, revolving door is electronically controlled, but the initial stage is bought relatively costly with what the later stage used.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, it is proposed to a kind of Cam intermittent control structure for revolving door focusing on second protection.
This utility model solves it and technical problem is that and take techniques below scheme to realize:
A kind of Cam intermittent control structure for revolving door, including inner rotary table, outer rotary table, cam, push rod, alignment pin and spring, inner rotary table outer rim coaxial package outer rotary table, a cam it is co-axially mounted in the middle part of inner rotary table, this cam is shaped with the cam that two specular are protruding, each projection on this cam realizes one-directional rotation with a push rod respectively and coordinates, each push rod and the position of projection contacts are shaped with top, one end of each push rod is fixed by alignment pin and inner rotary table, stud connection is passed through in one end of the other end and a spring, the other end of spring is fixed by another alignment pin and inner rotary table.
And, described outer rotary table and revolving door top are fixedly mounted with.
Advantage of the present utility model and having the benefit effect that
The cam of the Cam intermittent control structure for revolving door that this utility model provides and push rod realize positive movement by rotating rotating and reverse of axle, the structure of reverse mismatch, when positive movement, cam lobe and push rod top drive inner rotary table and outer rotary table motion by frictional force, revolving door rotates, during reverse movement, cam lobe and push rod top mismatch, rotate the idle running of axle band moving cam, revolving door does not turn, and rotates and reverse the tapping mode realizing revolving door from there through motor rotation axis, simple and reasonable, it is easily installed, uses and maintenance cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model (vertical view).
Detailed description of the invention
Implementing to be further described to this utility model below in conjunction with accompanying drawing, following example are illustrative, are not determinate, it is impossible to limit protection domain of the present utility model with this.
A kind of Cam intermittent control structure for revolving door, including inner rotary table 5, outer rotary table 4, cam 9, push rod 7, alignment pin and spring 2, inner rotary table outer rim coaxial package outer rotary table, a cam it is co-axially mounted in the middle part of inner rotary table, this cam is shaped with the cam that two specular are protruding, projection can be multiple, must be arranged on cam uniformly at intervals, each projection on this cam realizes one-directional rotation with a push rod respectively and coordinates, each push rod and the position of projection contacts are shaped with top 6, one end of each push rod is fixed by alignment pin 8 and inner rotary table, one end of the other end and a spring is connected by hinge 3, the other end of spring is fixed with inner rotary table by another alignment pin 1, push rod and spring is thus made to realize hinge structure, realize being rotatably assorted by frictional force between cam lobe and push rod top, simultaneously the top on push rod is subjected to the power that cam lobe drives and decomposes, obtain the pressure of steering force and pressuring spring.
Operation principle of the present utility model is:
During use, being coaxially fixedly mounted with realization by axle key with electric machine rotational axis 10 and drive in the middle part of cam, outer rotary table and revolving door top are fixedly mounted with, cam and push rod realize positive movement by rotating rotating and reverse of axle, the structure of reverse mismatch, when positive movement, cam lobe and push rod top drive inner rotary table and outer rotary table motion by frictional force, outer rotary table and revolving door are fixed, revolving door rotates, and during reverse movement, cam lobe comes directly towards mismatch with push rod, rotating the idle running of axle band moving cam, revolving door does not turn.
Although disclosing embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope without departing from this utility model and claims, various replacements, to change and modifications be all possible, therefore, scope of the present utility model is not limited to embodiment and accompanying drawing disclosure of that.
