Abstract

The utility model discloses a magnetic door opening device, which comprises a door frame; wherein a door cover is arranged on the door frame; a rotating shaft is arranged on the door cover; a handle is arranged on the rotating shaft; a connecting rod is arranged at one side of the rotating shaft; the end part of the connecting rod is provided with a first magnet; a fixing plate is arranged at the inner side of the door frame; a second magnet is arranged on the fixing plate; and a third magnet is also arranged on the fixing plate. A clamp ring is arranged at one side of the door frame; a bulge plate is arranged on the door cover; and the clamp ring is matched with the bulge plate. The magnetic door opening device has the advantages that the structure is rational, the door cover is firmly fixed, the opening and closing are convenient, and the situation in which the door cover cannot be opened owing to rusting cannot occur.

Description

The magnetic force door opener

Technical field

The utility model relates to a kind of opening and closing device of appliance doors, specifically a kind of magnetic force door opener.

Background technology

Many equipment all need be installed the door closure for operation or maintenance usefulness on housing, door closure mostly passes through snap close or snap fit on door frame, but because some door closure frequency of utilization is lower, do not use for a long time to cause snap close or buckle corrosion distortion, door closure can't normally be opened.

Summary of the invention

The purpose of this utility model provides a kind of magnetic force door opener, and its adopts the mode of magnetic force with door closure and door frame adhesive, the situation that the door closure of avoiding occurring causing because of corrosion can't be opened.

The utility model for achieving the above object, be achieved through the following technical solutions: comprise door frame, door closure is installed on the door frame, rotating shaft is installed on the door closure, mounting knob in the rotating shaft, rotating shaft one side is installed connecting rod, and first magnet is installed in the connecting rod end, door frame installed inside fixed head is installed second magnet on the fixed head.The 3rd magnet also is installed on the fixed head.Door frame one side is provided with snap ring, and door closure is provided with lug, and snap ring matches with lug.

Advantage of the present utility model is: reasonable in design, the door closure fixation is opened, is closed conveniently, the situation that the door closure that can not occur causing because of corrosion can't be opened.

Description of drawings

Fig. 1 is the utility model structural representation; Fig. 2 is the backsight structural representation of Fig. 1; Fig. 3 is an I portion structure for amplifying schematic diagram among Fig. 1; Fig. 4 is the structural representation that handle goes to the enable possition among Fig. 3.

The specific embodiment

Magnetic force door opener described in the utility model comprises door frame 1, door closure 2 is installed on the door frame 1, rotating shaft 3 is installed on the door closure 2, mounting knob 4 in the rotating shaft 3, rotating shaft 3 one sides are installed connecting rod 5, and first magnet 6 is installed in connecting rod 5 ends, door frame 1 installed inside fixed head 7, the pole orientation that second magnet, 8, the second magnet 8 are installed on the fixed head 7 is identical with first magnet 6.Handle 4 can drive connecting rod 5 rotations by rotating shaft 3, when user's swing handle 4, when connecting rod 5 drives first magnet 6 goes to second magnet, 8 places, because the pole orientation of second magnet 8 is identical with first magnet 6, so the magnetic pole of first magnet 6 and second magnet, 8 contact surfaces is a heteropole,

first magnet

6 and 8 adhesives of second magnet, door closure 2 is closed condition; When connecting rod 5 drove the magnetic force scope of first magnet, 6 disengagings, second magnet 8, door closure can be opened.

Open door closure 2 for the convenience of the users, the 3rd magnet 9 can be installed on fixed head 7 described in the utility model, the pole orientation of the 3rd magnet 9 is opposite with first magnet 6, when user's swing handle 4, when connecting rod 5 drives first magnet 6 goes to the 3rd magnet 9 places, because the pole orientation of the 3rd magnet 9 is opposite with first magnet 6, so the magnetic pole of first magnet 6 and the 3rd magnet 9 contact surfaces is a homopolarity, first magnet 6 and the 3rd magnet 9 repel mutually, door closure 2 can be automatically springed open.

In order to make door closure 2 more firm being fixed on the door frame 1 described in the utility model, also can adopt following structure: door frame 1 one sides are provided with snap ring 10, and door closure 1 is provided with lug 11, and snap ring 10 matches with lug 11.Adopt this structure one side of door closure 1 can be fixed, door closure 1 is opened to a side only, has reduced the load-bearing of magnet adhesive place, the situation of door closure 2 accidental can not occur.
