The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

In this embodiment, a hidden door handle is disclosed, and fig. 1 shows a three-dimensional structure of a section of the hidden door handle; fig. 2a and 2b show the three-dimensional structure of the concealed door handle at two different angles, wherein fig. 1 to 2b only show the structure related to the concealed door handle and the pivotal connection thereof, and the structure in other door locks is not the innovation point of the present application, and is not shown in the drawings.

Referring to fig. 1 to 2b, the concealed door handle is installed on a door at a position opposite to a door lock 3, and includes: a handle 1 and a knob 2. Wherein the handle 1 is in a strip structure, and the outer side of the handle is provided with an inwards concave installation position 11 for installing the knob 2. The middle part of the mounting position 11 is provided with a fitting hole 12, and the inside of the knob 2 is provided with a connecting part 21 which can be inserted into the fitting hole 12. Through inserting connecting portion 21 in the pilot hole 12, can rotate knob 2 and install on installation position 11 to when the door is closed state, when knob 2 was in the initial position, the lateral surface of knob 2 was parallel and level with the lateral surface of handle 1, and knob 2 and handle 1 present integral type structure in the outward appearance this moment, can make the outward appearance of the door body succinct pleasing to the eye more. In addition, a square core hole 22 which can be connected with the square core 31 of the door lock 3 is arranged at the inner end of the connecting part 21, and the knob 2 and the door lock 3 can be connected together by inserting the square core 31 into the Fang Xinkong. When the lock is unlocked or unlocked, the knob 2 is rotated firstly, the knob 2 can drive the square core 31 to rotate, the square core 31 drives the peach pulling device in the door lock 3 to rotate, and then other linkage mechanisms are driven to eject or retract the lock tongue, so that the lock is unlocked or unlocked, and after the lock is unlocked, the door can be opened by pulling the handle 1. The door lock 3 is a prior art, and specific structures and principles thereof are not described herein.

In this embodiment, the inner side of the handle 1 is provided with a spring groove 13 intersecting the assembly hole 12, a ball 131 and a compression spring 132 are provided in the spring groove 13, in addition, in this embodiment, the ball 131 abuts against the compression spring 132, the compression spring 132 can apply a force to the ball 131 by its own elasticity, and this arrangement can also ensure that the force between the ball 131 and the compression spring 132 is balanced. The connecting portion 21 is further provided with a recess 211 facing the spring groove 13 and accommodating a side surface of the ball 131. It can be seen that the balls 131 can be locked into the concave portion 211 by the pushing force of the compression spring 132 to fix the connecting portion 21, thereby achieving the effect of positioning the knob 2.

In this embodiment, the connecting portion 21 is symmetrically provided with two or more concave portions 211. When the door needs to be opened, after the user rotates the knob 2 by a certain angle, under the thrust of the compression spring 132 to the balls 131, the balls 131 are clamped into the corresponding concave portions 211, so that the knob 2 can be positioned at 180 °, 120 ° or 90 °.

In addition, in this embodiment, the surfaces of the connecting portions 21 on both sides of the recess portion 211 are provided with the moving surfaces, and the distance between the moving surfaces and the axis of the connecting portion 21 gradually increases from one end near the recess portion 211 to the other end, so that the direction of the acting force of the ball 131 by the compression spring 132 and the tangent line of the moving surfaces are not perpendicular to each other, but rather present a certain angle. In this case, the balls 131 apply a certain force to the running surface, and the connecting portion 21 is rotated. When the door needs to be opened, the user rotates the knob 2, the balls 131 move from the concave portions 211 to be in contact with the moving surfaces, and in the rotation process of the knob 2, the compression springs 132 are further compressed under the pushing action of the moving surfaces on the balls 131, when the knob 2 rotates to any angle, the compression springs 132 recover when the balls 131 move from the moving surfaces to the corresponding concave portions 211, and under the pushing action of the compression springs 132, the balls 131 are clamped into the concave portions 211, and at the moment, the corresponding angle positioning of the knob 2 can be achieved. Meanwhile, in the rotating process, under the driving of the knob 2, the square core 31 can drive the peach poking in the door lock 3 to rotate so as to drive other linkage mechanisms to extend or retract the lock tongue, and thus, the locking or unlocking is realized. In the rotation process, if the ball 131 does not reach the other concave portion 211, and when the user releases the knob 2, the ball 131 abuts against the moving surface at this time, and the ball 131 pushes the connecting portion 21 to rotate under the elastic force of the compression spring 132, that is, slowly moves along the moving surface and returns to the previous concave portion 211, so that the knob 2 automatically returns to the initial position, and continues to form an integral structure with the handle 1, so that the user can experience that only the handle 1 is provided without the knob 2.

As shown in the drawings, in this embodiment, the inside of the connecting portion 21 is fitted with a baffle 4 covering the side face of the spring groove 13. The baffle 4 can act to shield and fix the compression spring 132.

In addition, in this embodiment, the connection portion 21 is sleeved with a clamp spring located inside the baffle 4, so that the baffle 4 can be limited. Meanwhile, the clamp spring is a common part, is easy to obtain and has low cost. Further, the baffle 4 may be directly fixed to the handle 1 by a screw or the like.

Further, in this embodiment, the fitting hole 12 is a circular hole, and the front end of the connecting portion 21 is a cylindrical shape having a stepwise change in outer diameter. The design can realize the rotation function of the knob 2, and simultaneously, the front end of the connecting part 21 is arranged into a cylindrical shape with the outer diameter changing in a step-like manner, so that the installation of other parts can be facilitated.

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 utility model may be embodied in other specific forms without departing from the spirit or essential characteristics 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. Any reference sign in a claim should not be construed as limiting the claim concerned.
