Description
Technical field
The invention belongs to a kind of door closer-holder, especially relate to a kind of multipoint positioning cam.
Background technology
Cam is arranged in floor spring, and in use, door rotational band moving cam rotates, and cam opposite house carries out load-bearing, Men Ke
To rotate on cam, it is achieved open the door and close the door.But existing cam typically only has door to open 90 ° or 360 ° of arbitrarily angled unlatchings
Two kinds；When door opens 90 °, door easily swings when by external forces such as extraneous large winds, and door easily occurs
Damage, affect service life.
Summary of the invention
It is an object of the invention to provide a kind of multipoint positioning cam, it is possible to solve at least one in the problems referred to above.
According to an aspect of the invention, it is provided a kind of multipoint positioning cam, including body, body is provided with the first groove
Being two with the second groove, the first groove and the second groove, two the first grooves are symmetrical relative to the centrage of body, two
Second groove is symmetrical relative to the centrage of body, and when door is closed, the first groove matches with the roller of floor spring
Close；
When the opening angle of door is 120 °, the second groove matches with the roller of floor spring.
The invention has the beneficial effects as follows: be provided with the first groove and the second groove so that cam be closed at door and
When opening 120 °, it is achieved location, convenient use；It is provided with the second groove so that door realizes the location of door when opening 120 °, works as wind
When power or other active forces are bigger, wind is unloaded power by the both sides of door by realization, effectively prevent a swing, meets needs big simultaneously
Angle opens the access door or greeting door and needs needing again to open for a long time, improves the security performance of door, improves making of door
Use the life-span.
In some embodiments, body is provided with the 3rd groove, and the 3rd groove is two, is positioned at the first groove and second recessed
Between groove, when the opening angle of door is 90 °, the 3rd groove matches with the roller of floor spring.Thus, it is provided with the 3rd groove,
Can be the location that many angles are provided in door opening process, improve the scope of application.
In some embodiments, the cross section of the second groove is circular arc, this circular arc place circle radius be 35～
45mm.Thus, it is simple to the second groove coordinates with roller.
In some embodiments, the cross section of the 3rd groove is circular arc, and the radius of this circular arc place circle is 4～6mm.
Thus, it is simple to the 3rd groove coordinates with roller.
In some embodiments, the first groove is provided with projection, when door is closed, and protruding and two rollers
Corresponding.Thus, it is provided with projection, stability when door is closed can be increased, increase enabling power, effectively keep the closedown shape of door
State.
In some embodiments, the arc radius between the first groove and the 3rd groove is 18～25mm.Thus, it is simple to
The smooth pivotal of cam.
In some embodiments, body is provided with the 4th groove, and the 4th groove is two, is positioned at the second groove side, when
When the opening angle of door is 135 °, the 4th groove matches with the roller of floor spring.
Accompanying drawing explanation
Fig. 1 is the structural representation of the multipoint positioning cam of the present invention.
Detailed description of the invention
The present invention is further detailed explanation below in conjunction with the accompanying drawings.
With reference to Fig. 1: multipoint positioning cam, including body 1, body 1 is provided with the first groove 2 and the second groove 3, the first groove
2 and second groove 3 be two, two the first grooves 2 are symmetrical relative to the centrage of body 1, two the second grooves 3 relative to
The centrage of body 1 is symmetrical, and when door is closed, the first groove 2 matches with the roller of floor spring；
When the opening angle of door is 120 °, the second groove 3 matches with the roller of floor spring.
Thus, when door is opened into 120 °, by the second groove 3 and roller to coordinate opposite house to carry out spacing, prevent door and
Multipoint positioning cam occurs further to rotate so that door can be fixed on hexagonal angle degree position, thus when wind-force is bigger,
Wind can well realize unloading power by the both sides of door, it is therefore prevented that door swings, thus improves the security performance of use.
Body 1 is provided with the 3rd groove 4, and the 3rd groove 4 is two, between the first groove 2 and the second groove 3, works as door
Opening angle when being 120 °, the 3rd groove 4 matches with the roller of floor spring.
The cross section of the second groove 3 is circular arc, and the radius of this circular arc place circle is 35～45mm, preferably 40mm.From
And realize enabling power more than twice door closing force so that when door is in 135 ° of states of unlatching, by coordinating of the second groove 3 and roller
Realize spacing to cam, improve enabling power, keep door to be in opening, and door is still in opening when wind-force is slightly larger
State, prevents door from rocking, and improves the security performance of door, increases safety in utilization.
The cross section of the 3rd groove 4 is circular arc, and the radius of this circular arc place circle is 4～6mm, preferably 5.5mm.With
Reason, it is ensured that when door opening angle is 120 °, enabling power herein is more than twice door closing force, thus so that door can be protected
Holding steady statue, wind-force can be realized unloading power by the both sides of door, prevents door from rocking.
Being provided with protruding 5 at first groove 2, when door is closed, projection 5 is corresponding with two rollers.At door
When closed mode, the first groove 2 matches with roller, and protruding 5 are positioned at the side of the first groove 2, prevent cam at wind-force etc.
Rotate under active force, thus prevent door at extraneous wind-force effect lower swing, improve the security performance of door.
Arc radius between first groove 2 and the 3rd groove 4 is 18～25mm, preferably 20mm.Thus, opening when door
Opening angle when being between 120 °～135 °, this multipoint positioning cam can be with smooth pivotal, i.e. door can easily open promotion.
Body 1 is provided with the 4th groove 6, and the 4th groove 6 is two, is positioned at the second groove 3 side, when the opening angle of door is
When 135 °, the 4th groove 6 matches with the roller of floor spring.Thus, prevent cam from rotating under the active forces such as wind-force, from
And prevent door at extraneous wind-force effect lower swing, improve the security performance of door.
Thus, the multiple spot when multipoint positioning cam of the present invention can realize door closedown and door unlatching 120 ° and 135 ° is determined
Position, convenient use, facilitate door, when being in 120 ° and 135 °, wind-force is unloaded power, it is ensured that the safety in utilization of door.
Above-described is only the preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, it is also possible to make some deformation and improvement, these broadly fall into the present invention
Protection domain.
