Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The locking structure is suitable for a shielding door, when the locking structure is used, the handle component 1 is rotated to drive the locking component to act and be clamped with the clamping piece 2, the locking structure adopts a pure mechanical structure to lock, an electric part is not needed, the electromagnetic interference can be effectively reduced, and the specific action process is as follows:

as shown in fig. 1-3, when the shield door needs to be locked, the handle assembly 1 is rotated to drive the connecting rod 31 to move upwards (or downwards, specifically, the directions of different movements are different), the movement of the connecting rod 31 can drive the transmission block 32 to rotate around the rotating shaft 37, and the movement of the transmission block 32 drives the hook 33 to rotate synchronously through the rotating shaft 37, after the hook 33 rotates to a certain position, the hook 33 can be clamped and fixed with the clamping piece 2 fixed on the door frame, that is, the locking of the shield door is completed, the bearing 36 is arranged at the connection position of the rotating shaft 37 and the shield door, so that the friction force generated by the rotation of the bearing 36 is reduced, the locking and unlocking movements are smoother, and the force for people to rotate the handle assembly 1 is saved; when the shielding door needs to be opened, the handle assembly 1 is reset, namely the handle assembly 1 is rotated, the shielding door can be opened by referring to the steps, and the shielding door is very convenient to use; it should be noted that one side of the shield door is connected with the door frame through a hinge, and the shield door and the door frame are locked in the application, namely the other side of the shield door is attached and locked with the door frame;

in one embodiment, when the shielding door is not locked, the shielding door is attached to the door frame, the clamping hook 33 is gradually close to the clamping piece 2 by rotating the handle assembly 1, and finally the clamping piece 2 enters the arc-shaped groove 34 formed in the clamping hook 33, wherein the clamping piece 2 is arranged on the door frame of the fixing seat 21, the clamping hook 33 is arranged at the fixed position of the shielding door, along with the rotation of the clamping hook 33, the clamping piece 2 extends along the track of the arc-shaped groove 34 and gradually approaches the distance between the door frame and the shielding door, the door frame and the shielding door are already attached, namely, the door frame and the shielding door are mutually extruded, so that the locking effect is achieved;

still another embodiment, be located the opening part at joint spare 2, and when not getting into recess 34, door frame and shield door are not laminated, and there is the clearance, along with the action of handle subassembly 1 drive closure subassembly 3, make joint spare 2 get into recess 34 gradually, and make door frame and shield door laminate gradually and lock, joint spare 2 still can move and separate with pothook 33 along recess 34 orbit when opening the shield door so, at this in-process, the shield door also can separate gradually with the door frame, that is to say when rotating handle subassembly 1 unblock, can separate shield door and door frame simultaneously, the initial strength that the user pushed shield door open can be reduced to such design, under the prerequisite that can not influence the shielding effect, the strength of pushing shield door open has been saved, make things convenient for people's use.

The above two embodiments can also be used in combination with the protrusion 35, when the clip member 2 is located at the opening, and does not enter the groove 34, the convex block 35 is abutted against the door frame, so that the door frame is not attached to the shielding door, and a gap exists, the locking component 3 is driven by the handle component 1 to act, so that the clamping component 2 gradually enters the groove 34, but the door frame and the shielding door are gradually attached and locked, when the shielding door is opened, the clamping piece 2 still moves along the track of the groove 34 and is separated from the hook 33, in the process, no matter whether the groove 34 has the function of pushing open the shielding door or not, after the hook 33 rotates to a certain position, the edge of the convex block 35 is abutted against the door frame again, and along with the continuous rotation of the clamping hook 33, the convex block 35 can eject the shielding door out of the door frame again, so that the shielding door is separated from the door frame, the force for pushing the shielding door open is saved, and the use of people is facilitated.

In this embodiment, the clamping member 2 is divided into the fixing seat 21 mounted on the door frame and the clamping portion 22 clamped with the groove 34, and the roller 23 is arranged on the clamping portion 22, so that the roller 23 can abut against the inner wall of the groove 34, and friction force can be reduced;

in this embodiment, as shown in fig. 4 and 5, the handle assembly 1 also needs to have a corresponding structure for cooperating with the action of the locking assembly 3, wherein the connecting rod 31 in the locking assembly 3 is a rigid component, and when the two ends of the connecting rod 31 are not located on a plane, the driving block 32 cannot be driven to rotate;

more specifically, the mounting seat 12 is fixedly arranged on the shield door, the shaft core 11 is connected with the mounting seat 12 through threads, when the shielding door is used, the handle 17 rotates the shaft core 11 and simultaneously drives the connecting plate 13 to rotate, the connecting plate 13 also synchronously drives the connecting rod 31 to act, the number of turns of the threads corresponds to the rising amount of the end part of the connecting rod 31, so that the extending position of the shaft core 11 can be accurately controlled, an additional limiting structure is not required to be added, and the shielding door is relatively simple and easy to manufacture;

in addition, in order to enhance the shielding effect, an antimagnetic structure is further arranged between the shaft core 11 and the mounting seat 12, and the shielding door is in a normal state when being closed, because the end cover 14 is fixed on the shaft core 11, the mounting seat 12 extends into a certain position of the shaft core 11 and then abuts against the end cover 14, the flange 15 arranged on the end cover 14 also enters the groove 16 of the mounting seat 12, so that the end cover 14 and the mounting seat 12 form a whole, and after contacting the door core, an external electromagnetic signal is sequentially transmitted to the shaft core 11, the end cover 14 and the mounting seat 12, and finally the antimagnetic material arranged in the groove 34 is used for shielding, so that the purpose of shielding the electromagnetic signal is achieved, and the common antimagnetic material is a copper mesh.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
