Third embodiment, the present embodiment is a description of the hinge assembly 3, and refer to fig. 3 to 5;

the installation mode of the hinge in the embodiment is the same as or similar to that of a hinge on the market, and is not described herein again, after the installation is completed, the shielding door is downward under the gravity, that is, the hinge is used as a middle part of the door frame 1 and the shielding door to be stressed, when the shielding door is used, the shielding door is opened or closed, the hinge first 31 and the hinge second 33 rotate relatively through the hinge first 32 and the hinge second 34, and because the bearing 35 is arranged between the hinge first 32 and the hinge second 34, the gravity of the shielding door can be applied to the bearing 35 at the moment, when the shielding door rotates, the bearing 35 can greatly reduce the friction between the hinge first 32 and the hinge second 34, so that a user can open or close the shielding door without strong effort, and the shielding door can be conveniently used by people;

to explain further, the bearing 35 used here is a plane bearing 35, the plane bearing 35 is a component composed of a plane retainer assembly with needle roller or cylindrical roller or steel ball and a plane washer, and is held and guided by the plane retainer, and the hinge sheet one 31 also rotates in a plane, the plane main bearing 35 can be used for better stress, and the friction is smaller, and the rotation is smoother;

in this embodiment, a gap of 1mm-2mm exists between the first hinge part 32 and the second hinge part 34, and when the installation is not in place, the gap between the first hinge part 32 and the second hinge part 34 can be adjusted by the adjusting structure 36, for example, the shielding door is installed on the door frame 1, the first hinge piece 31 can be adjusted downward by the adjusting structure 36, so that the shielding door is aligned with the door frame 1, and the bearing 35 will abut against the adjusting structure 36, so that the normal use of the bearing 35 will not be affected;

more specifically, the adjusting structure includes at least one screw hole 361 disposed at the second hinge portion 34, and in the present embodiment, the number of the screw holes 361 is two, and in use, by adjusting the position of the screw 362 in the screw hole 361, the end of the screw 362 is abutted against the side of the bearing 35 close to the second hinge portion 34, for example: the screw 362 continuously penetrates into the screw hole 361, so that the gap between the first hinge part 32 and the second hinge part 34 close to one end of the adjusting structure is gradually increased, that is, the shielding door is adjusted upwards, otherwise, the shielding door is adjusted downwards;

certainly, both ends of the second hinge portion 34 can be provided with an adjusting structure, when in use, the screw 362 in the adjusting structure at one end of the second hinge portion 34 gradually extends into the screw hole 361, and the screw 362 in the adjusting structure at the other end of the second hinge portion 34 gradually exits from the screw hole 361, so that the screw 362 can be abutted against the bearings 35 at both ends in a matching manner, the structure is more compact, the more the screw holes 361 are, the more the screws 362 are, the more the bearing 35 is stressed, and meanwhile, the flat head screws 362 can be used as the screws 362.

Fourth, the present embodiment is described with reference to fig. 6 and 7 for the handle assembly 4 and the locking assembly 5;

during the use, can drive the built-up components action and with joint 55 block through rotating handle subassembly 4, adopt pure mechanical structure to lock, need not to use electronic component, can effectively reduce electromagnetic interference, specific action process as follows:

when the shielding door needs to be locked, the connecting rod 51 is driven to move upwards (or downwards, and the specific setting directions are different) by rotating the handle assembly 4, the transmission block 52 can be driven to rotate by taking the rotating shaft 53 as the center through the movement of the connecting rod 51, the movement of the transmission block 52 synchronously drives the hook 54 to rotate through the rotating shaft 53, and the hook 54 can be clamped and fixed with the clamping piece 55 fixedly arranged on the door frame 1 after rotating to a certain position, so that the locking of the shielding door body 2 is completed, the bearing 35 is arranged at the connecting part of the rotating shaft 53 and the shielding door, the rotating friction force of the bearing 35 is reduced, the locking and the unlocking are smoother, and the force for rotating the handle assembly 4 by people is saved; when the shielding door body 2 needs to be opened, the handle assembly 4 is reset, namely the handle assembly 4 is rotated, the shielding door can be opened by referring to the steps, and the use is very convenient; it should be noted that, one side of the shield door is connected with the door frame 1 through a hinge, and the locking of the shield door body 2 and the door frame 1 in the embodiment means that the other side of the shield door is attached and locked with the door frame 1;

in one embodiment, when the shielding door is not locked, the shielding door body 2 is attached to the door frame 1, the hook 54 is gradually close to the clamping piece 55 by rotating the handle assembly 4, and finally the clamping piece 55 enters the arc-shaped groove 56 formed in the hook 54, wherein the clamping piece 55 is fixed on the door frame 1, the hook 54 is installed at a fixed position on the shielding, the clamping piece 55 extends along the track of the arc-shaped groove 56 and gradually approaches the distance between the door frame 1 and the shielding door, and the door frame 1 and the shielding door are already attached, that is, the door frame 1 and the shielding door are mutually extruded, so that the locking effect is achieved;

in another embodiment, when the clip 55 is located at the opening and does not enter the groove 56, the shielding position two 21 does not completely enter the shielding position one 11, and the locking assembly 5 is driven by the handle assembly 4 to move, so that the clip 55 gradually enters the groove 56, but the shielding position two 21 gradually enters the shielding position one 11, so that the shielding door body 2 is attached to and locked with the door frame 1, and due to the clamping action of the shielding elastic assembly, the shielding door body 2 can be pushed away from the door frame 1 by using a large force, so that the clip 55 still moves along the track of the groove 56 to separate from the hook 54 when the shielding door body 2 is opened, in this process, the shielding door body 2 can also gradually separate from the door frame 1, that is, when the handle assembly 4 is rotated to unlock, the shielding door body 2 can be separated from the door frame 1 at the same time, and such design can reduce the initial force of the user for pushing the door open, under the prerequisite that can not influence shielding effect, saved the strength that pushes away the shield door, made things convenient for people's use.

The above two embodiments can also be used in combination with the protrusion 57, when the clamping member 55 is located at the opening and does not enter the groove 56, the protrusion 57 abuts against the door frame 1, and the shielding position two 21 does not completely enter the shielding position one 11, the clamping member 55 gradually enters the groove 56 as the handle assembly 4 drives the locking assembly 5 to move, but the shielding position two 21 gradually enters the shielding position one 11, so that the shield door body 2 is attached to and locked with the door frame 1, when the shield door body 2 is opened, the clamping member 55 still moves along the track of the groove 56 and separates from the hook 54, during this process, no matter whether the groove 56 has the effect of pushing open the shield door, after the hook 54 rotates to a certain position, the edge of the protrusion 57 will again abut against the door frame 1, and as the hook 54 continues to rotate, the protrusion 57 will push out the shield door body 2 from the door frame 1 again, make shielding door body 2 and door frame 1 separation, saved the strength that pushes away shielding door body 2, make things convenient for people's use.

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.
