In addition to the function of opening and closing the lock, the door handle 1000 also requires a great aesthetic appearance, such as screws that do not allow the mounting seat to be seen. To solve this problem, a rotating handle 100 of the related art is generally provided with a mounting seat and an outer cover 400, the mounting seat is connected with the rotating handle 100, after the mounting seat is fixedly connected to the door body by a fastener, the outer cover 400 is moved along the rotating handle 100 and finally covered on the mounting seat, and after the mounting is completed, the screw is hidden. However, this solution may restrict the shape of the handle 100, and since it is required that the outer cover 400 can be moved along the handle 100 to the mounting seat, the handle 100 is generally cylindrical, such as the shape of the handle 100 shown in fig. 1, but the present invention may not be limited to the shape of the handle 100 shown in the drawings.

In order to solve the above problems, referring to fig. 1 to 6, the present invention provides a door handle 1000, which can hide fasteners such as screws and bolts on a fixing base 300, and can be designed into different shapes according to preferences of different people, without restriction on the shape of the handle, thereby improving product competitiveness.

Referring to fig. 1 to 5, in some embodiments, a door handle 1000 includes a twist grip 100, a snap seat 200, and a fixed seat 300. The rotating handle 100 is connected to a square bar (not shown), for example, a square groove 111 is formed at one end of the rotating handle 100, and the square bar is partially disposed in the square groove 111, so that the rotating handle 100 rotates to drive the square bar to rotate synchronously. The square bar is used for controlling the opening and closing of the lockset, and the door can be opened or closed by rotating the rotating handle 100.

Referring to fig. 5, the clamping seat 200 includes a first mounting portion 201 and a first connecting portion 202, the first connecting portion 202 is disposed around the first mounting portion 201, and the first mounting portion 201 is disposed with a through hole, for example, in the middle, so that the clamping seat 200 can penetrate through one end of the rotating handle 100 and can be rotatably connected. The card socket 200 may be in a circular cover shape, and the inner sidewall of the card socket 200 is provided with an abutting portion 210, for example, the abutting portion 210 is in a convex round point shape. The fixing base 300 includes a second mounting portion 310 and a second connecting portion 320, and the second connecting portion 320 is disposed around an edge of the second mounting portion 310. The fixing base 300 may also be in the shape of a circular cover, for example, the second mounting portion 310 is a cover bottom, and the second connecting portion 320 is a side surrounding portion of the cover.

Referring to fig. 3, in some embodiments, the limiting portion 321 includes a first limiting protrusion 3211 and a second limiting protrusion 3212, the first limiting protrusion 3211 is configured to limit a rotation angle of the bayonet socket 200, and the second limiting protrusion 3212 is configured to limit the bayonet socket 200 from disengaging from the fixing base 300. For example, the first position-limiting protrusion 3211 extends along the wall surface of the second connecting portion 320 in a direction close to the second mounting portion 310, and the second position-limiting protrusion 3212 extends along the outer edge of the second connecting portion 320 and is perpendicular to the first position-limiting protrusion 3211. It can be understood that when the snap-fit socket 200 is screwed on the fixing socket 300, the abutting portion 210 can abut against the first position-limiting protrusion 3211 to perform a positioning function, so as to enable the handle to be located at a substantially parallel position. When the handle 100 is pulled outward, the abutting portion 210 can abut against the second limiting protrusion 3212, so as to limit the engaging seat 200 from disengaging from the fixing seat 300. It should be noted that the term "substantially parallel" mentioned in the embodiments of the present invention may be understood as parallel, nearly parallel, or having a predetermined angle.

It should be noted that, in other embodiments, the first limiting protrusion 3211 may also be in the shape of an arc, and the second limiting protrusion 3212 is tangent to the arc-shaped first limiting protrusion 3211.

Referring to fig. 3 and 4, in some embodiments, the first and second limiting protrusions 3211 and 3212 are connected to each other and define two mounting grooves 301, and the two mounting grooves 301 are respectively located at two sides of the first limiting protrusion 3211. The mounting groove 301 has a width L, which is the shortest distance between the second mounting portion 310 and the second stopper protrusion 3212, and the width L gradually decreases along a direction approaching the first stopper protrusion 3211. It can be understood that, in the process of rotationally connecting the abutting portion 210 and the limiting portion 321, the L gradually decreases, that is, the connection between the socket 200 and the fixing base 300 is gradually clamped, so that the risk of dropping the socket 200 can be reduced. Because the door handle 1000 installation direction of inside and outside both sides is inconsistent, therefore be provided with two mounting grooves 301 and can improve the commonality of fixing base 300, the door inside and outside can general one type fixing base 300, reduces manufacturing cost, reduces the condition of installation mistake.

Referring to fig. 2 and 3, in some embodiments, there are at least two, such as two, abutments 210, one above the other. The number of the stopper portions 321 is the same as the number of the abutting portions 210, and the stopper portions 321 are provided at positions corresponding to the positions of the abutting portions 210, for example, the stopper portions 321 are provided at both upper and lower positions. It will be appreciated that the provision of a plurality of abutments 210 may improve the stability of the snap fit and reduce the risk of disengagement.

The direct mount includes that fixing base 300 is direct and tool to lock fixed connection, and the indirect mounting includes that the tool to lock sets up on the door, and fixing base 300 fixed connection waits the condition on the door.

In the installation process of the door handle 1000, the fixing seat 300 is fixed on the door, the engaging seat 200 can be directly connected with one end of the rotating handle 100, then the engaging seat 200 is screwed on the fixing seat 300, and the abutting part 210 abuts against the limiting part 321 to limit the engaging seat 200 to be separated from the fixing seat 300. Therefore, the shape of the rotating handle 100 is not limited, and can be designed into various forms. The fastening seat 200 may be designed in the shape of the outer cover 400, so that the fastening seat 200 covers the fixing seat 300, thereby hiding the mounting structures such as screws on the fixing seat 300 and improving the aesthetic appearance of the door handle 1000.

It will be appreciated that one way of mounting is: the clamping seat 200 and the rotating handle 100 integrally rotate along the second direction, and then are connected with the fixed seat 300 in a screwing way. Referring to fig. 2, the direction of the arrow in fig. 2 is a first direction. The stop piece 500 is engaged with the mounting end 110 of the rotating handle 100 and can rotate synchronously, and the second engaging portion 530 of the stop piece 500 abuts against the limiting member 230 of the engaging seat 200. If the rotating handle 100 can rotate along the first direction when in the locked position, the second engaging portion 530 drives the engaging seat 200 to rotate along the first direction, so as to cause the engaging seat 200 to disengage from the fixing seat 300. The square bar is connected to the mounting end 110 of the rotating handle 100, and the square bar cannot rotate in the first direction when in the locking position, and the rotating handle 100 and the square bar rotate synchronously, so that the rotating handle 100 cannot rotate in the first direction, and the rotating handle 100 and the engaging seat 200 cannot rotate integrally in the first direction to disengage the engaging seat 200 from the fixing seat. Therefore, the square bar can further limit the disengagement of the engaging seat 200 from the fixing seat 300.

Although the engaging seat 200 can also be rotated to the disengaging position along the first direction, the door handle 1000 of the present application only rotates the rotating handle 100 during the daily use, does not rotate the engaging seat 200, and can reset the engaging seat 200 to the position where the abutting portion 210 abuts against the limiting portion 321 under the elastic force of the flat spring 600, so that the engaging seat 200 is difficult to disengage from the fixing seat 300.

The other installation mode is as follows: since the door handle 1000 on one side is mounted, the square bar is also mounted in the door body. The door handle 1000 on the other side cannot be directly mounted by integral rotation. Therefore, the door handle 1000 on the other side needs to rotate the snap seat 200 in the direction away from the turn buckle, then the rotating handle 100 is connected with the square rod, then the hand is released to release the snap seat 200, the snap seat 200 can rotate in the turn buckle direction under the elastic force of the flat spring 600, and meanwhile, the rotation can be assisted by the hand to enable the abutting part 210 to abut against the limiting part 321, so that the relative position of the snap seat 200 and the fixed seat 300 is fixed.

The present invention also proposes a door including the door handle 1000 of the above embodiment. The door handle 1000 includes a twist grip 100, a snap seat 200, and a fixing seat 300. The rotating handle 100 is connected to a square bar (not shown), for example, a square groove 111 is formed at one end of the rotating handle 100, and the square bar is partially disposed in the square groove 111, so that the rotating handle 100 rotates to drive the square bar to rotate synchronously. The square bar is used for controlling the opening and closing of the lockset, and the door can be opened or closed by rotating the rotating handle 100.
