Detailed Description

The invention has the core that the bidirectional limiting door lock is provided, the inward limiting and the outward limiting can be realized through the door lock, and a limiting structure is not required to be arranged on a cabinet body independently, so that the structure is simplified.

In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the bidirectional position limiting door lock of the present invention in detail with reference to the accompanying drawings and the specific embodiments.

Fig. 1 is a schematic structural view of a bidirectional limiting door lock according to the present invention; the bidirectional limiting door lock comprises a rotating handle 1, a handle clamping seat 2, a rotating shaft 3 and other structures, wherein one of the rotating handle 1 and the handle clamping seat 2 is arranged on a cabinet door, and the other is arranged on a cabinet body.

The handle clamping seat 2 is a fixed structure; the rotating shaft 3 is fixedly arranged, the rotating handle 1 is rotatably arranged on the rotating shaft 3, the rotating handle 1 can rotate around the rotating shaft 3, the rotating shaft 3 is perpendicular to the surface on which the rotating handle is arranged, and the plane on which the rotating handle 1 rotates is parallel to the surface on which the rotating handle is arranged.

The handle 1 is rotated and is provided with the two-way locking block 11, the two-way locking block 11 is of a circumferential protruding structure, the distance between the far end of the two-way locking block 11 and the rotating shaft 3 is larger, and a convex block is formed on the periphery of the handle 1. When the bidirectional locking block 11 rotates to a locking state, the bidirectional locking block can be clamped into the bidirectional clamping groove 21 arranged on the handle clamping seat 2, and the handle 1 and the handle clamping seat 2 are mutually matched to limit inward and outward opening of the cabinet door. Fig. 2A is a schematic front view of the twist grip 1 in an unlocked state; fig. 2B is a schematic front view of the twist grip 1 in the locked state; the turning handle 1 is turned in the direction of the arc arrow in fig. 2A, and can be turned to the state shown in fig. 2B.

Because the radius of the position of the bidirectional locking block 11 is larger, the bidirectional locking block 11 can rotatably extend into the bidirectional clamping groove 21; fig. 3 is a schematic structural diagram of the handle holder 2; when the bidirectional locking block 11 is clamped in, the bidirectional locking block is blocked by two side walls of the bidirectional clamping groove 21 and cannot move in the axis direction of the rotating shaft 3, so that the cabinet door cannot rotate inwards or outwards relative to the cabinet body, and bidirectional limiting is realized; the invention realizes bidirectional limit to the cabinet body only by depending on the structure of the door lock, and has no other structure, thereby simplifying the structure of the cabinet body.

On the basis of the scheme, the side wall of the rotating shaft 3 is provided with a positioning hole, the rotating handle 1 is provided with a locking spring pin 4, and the locking spring pin 4 is assembled on the rotating handle 1 in a sliding mode and can stretch into the positioning hole formed in the rotating shaft 3 to achieve positioning. A sliding hole is formed in the rotating handle 1, the locking spring pin 4 is slidably arranged in the sliding hole, a spring is arranged, and the locking spring pin 4 has a tendency of moving inwards through the elastic force of the spring; set up two locating holes on the lateral wall of pivot 3, be located latched position and unblock position respectively, when rotating handle 1 and being in latched state and unblock state, the one end of locking spring catch 4 can be absorbed in the locating hole, prevents that personnel's mistake from touching and opens the door handle.

The rotating handle 1 is arranged on the cabinet door, and the handle clamping seat 2 is arranged on the cabinet body. Fig. 4 is a schematic view of the bidirectional limiting door lock of the present invention installed in a cabinet door and a cabinet body, wherein a represents the cabinet door.

In the embodiment, the rotating handle 1 is provided with a positioning lug 12, and the positioning lug 12 can contact the cabinet body to position the cabinet door; under the unblock state, location lug 12 stretches out from the edge of cabinet door, and when the cabinet door from opening the in-process that closes gradually, when the cabinet door reachd the angle of closing just, location lug 12 contacts the cabinet body, makes the unable further inward rotation of cabinet door.

Preferably, one side of the rotating handle 1 facing the cabinet door is provided with a rotation limiting arc groove 7, a rotation limiting pin is arranged on a rotation shaft seat of the cabinet door, and a rotation limiting convex block is inserted into the rotation limiting arc groove 7 to limit the rotating handle 1 to rotate within the range of the unlocking position and the locking position. Referring to fig. 2A, the arc-limiting groove 7 is an arc structure with a central angle of 90 degrees, so that the rotating handle 1 can only rotate within an angle range of about 90 degrees, and the angle range of the rotating handle 1 between the unlocking state and the locking state is limited.

The rotating handle 1 is provided with a pull rod 13 for hand operation, and the pull rod 13 is equivalent to a rod-shaped structure which is formed by the rotating handle 1 in a protruding mode along the circumferential direction, so that the acting force can be conveniently applied to the rotating handle 1 by the hand.

On the basis of any one technical scheme and the mutual combination thereof, the in-place sensor 5 is arranged in the handle clamping seat 2, the handle 1 is rotated to be provided with the detection block 6, and the in-place sensor 5 is used for sensing whether the detection block 6 is clamped in place or not; for some special operations, for example, when the cabinet door is closed, the system can inflate the air sealing ring of the cabinet door through the in-place detection signal to realize automatic sealing; because the coating pan body is arranged in the cabinet body and rotates, when the system monitoring cabinet door is not closed, the pan body can be controlled to be incapable of rotating in a linkage manner so as to avoid hurting people. The detection signal of the position sensor 5 is used to realize linkage with other operations.

The bidirectional locking groove 21 is a U-shaped groove which is transversely penetrated and has no bottom surface, and as shown in fig. 3, the bidirectional locking groove 21 is enclosed by the surfaces of the left side and the right side and the upper surface, and the lower part is open for the bidirectional locking block 11 to go in and out.

The invention also provides a coating machine shield shell which is wrapped with the bidirectional limiting door lock and can achieve the same technical effect.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
