The beneficial effects of the utility model are：It is provided with the first groove and the second groove so that cam is in door in closing shape
When state is with opening 120 °, positioning, convenient use is realized；It is provided with the second groove so that door realizes the positioning of door when opening 120 °,
When wind-force or other active forces larger, wind unloads power by the both sides of door by realization, effectively prevent a swing, while meeting need
Want wide-angle to open the access door or greeting door and needs for needing long-time to open again, improve the security performance of door, improve door
Service life.
In some embodiments, body is provided with the 3rd groove, and the 3rd groove is two, recessed with second positioned at the first groove
Between groove, when the opening angle of door is 90 °, the 3rd groove is engaged with the roller of floor spring.Thus, the 3rd groove is provided with,
Can be the positioning 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 in circular arc, and the radius of circle that the circular arc is located is 35～
45mm.Thus, it is easy to the second groove to coordinate with roller.
In some embodiments, the cross section of the 3rd groove is in circular arc, and the radius of circle that the circular arc is located is 4～6mm.
Thus, it is easy to the 3rd groove to coordinate with roller.
In some embodiments, the first groove is provided with projection, when door is closed, raised and two rollers
Corresponding.Thus, projection is provided with, stability when door is closed can be increased, increased enabling power, effectively keep the closing shape of door
State.
In some embodiments, the arc radius between the first groove and the 3rd groove are 18～25mm.Thus, it is easy to
The smooth pivotal of cam.
In some embodiments, body is provided with the 4th groove, and the 4th groove is two, positioned at the second groove side, when
When the opening angle of door is 135 °, the 4th groove is engaged with the roller of floor spring.
Description of the drawings
Fig. 1 is the structural representation of multipoint positioning cam of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in further detail.
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 is engaged with the roller of floor spring；
When the opening angle of door is 120 °, the second groove 3 is engaged with the roller of floor spring.
Thus, when door is opened into 120 °, carried out by the second groove 3 and the cooperation opposite house of roller spacing, prevent door and
There is further rotation in multipoint positioning cam so that door can be fixed on hexagonal angle degree position, so as to when wind-force is larger,
Wind can be very good to realize unloading power by the both sides of door, it is therefore prevented that door swings, so as to improve the security performance for using.
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 be 120 ° when, the 3rd groove 4 is engaged with the roller of floor spring.
The cross section of the second groove 3 is in circular arc, and the radius of circle that the circular arc is located is 35～45mm, preferably 40mm.From
And realize that enabling power is more than twice door closing force so that door is in when opening 135 ° of states, by the cooperation of the second groove 3 and roller
Realize to the spacing of 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 in circular arc, and the radius of circle that the circular arc is located 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, so as to so that door can be protected
Steady statue is held, wind-force can be realized unloading power by the both sides of door, prevent door from rocking.
Raised 5 are provided with first groove 2, and when door is closed, raised 5 is corresponding with two rollers.At door
When closed mode, the first groove 2 is engaged with roller, and raised 5 are located at the side of the first groove 2, prevent cam in wind-force etc.
Rotate under active force, so as to prevent door from lower swing is acted in extraneous wind-force, improve the security performance of door.
Arc radius between first groove 2 and the 3rd groove 4 are 18～25mm, preferably 20mm.Thus, opening when door
When opening angle between 120 °～135 °, the multipoint positioning cam can easily open promotion with smooth pivotal, i.e. door.
Body 1 is provided with the 4th groove 6, and the 4th groove 6 is two, positioned at 3 side of the second groove, when the opening angle of door is
When 135 °, the 4th groove 6 is engaged with the roller of floor spring.So as to, prevent cam from rotating under the active forces such as wind-force, from
And prevent door from acting on lower swing in extraneous wind-force, improve the security performance of door.
Thus, multipoint positioning cam of the present utility model can realize door close and door open 120 ° and 135 ° when multiple spot
Positioning, convenient use facilitate door to carry out unloading power to wind-force when being in 120 ° and 135 °, it is ensured that the safety in utilization of door.
Above-described is only preferred implementation of the present utility model, it is noted that for the ordinary skill of this area
For personnel, on the premise of design being created without departing from this utility model, can also make some deformations and improvement, these all belong to
In protection domain of the present utility model.
