Description

Technical Field

[0001] The utility model relates to the technical field of door locks, in particular to a door handle resetting structure. Background Art

[0002] Handle door locks are widely used in building structures, and are mainly used to open and close the lock body embedded in the door panel. The door handle lifting and pressing rotating structure with the publication number of "CN208220381U" includes a handle, a hollow base, and a handle head, a handle reset torsion spring and a handle sealing plate installed in the base. The handle head is in a "convex" shape, which rotates in the circular hole of the base and is exposed from the base to be connected with the handle; a pair of torsion spring push positions distributed at 180 degrees are provided on the periphery of the bottom of the handle head; a pair of spring stop positions distributed at 180 degrees for the torsion spring push position to rotate along its inner wall are provided in the base; after the handle reset torsion spring is twisted and broken apart, the spring arms at both ends of the handle reset torsion spring respectively cross the end faces of the torsion spring push position and the spring stop position at the same position at the same time; an extension arm is provided on the handle head; a limit opening is provided in the base for blocking the extension arm when the handle is lifted up to lock the door and pressed down to open the door; a square rod hole for inserting the square rod of the lock body is provided at the center of the inner end of the handle head.

[0003] Although the rotating structure in the above document requires fewer parts, and only a base, a handle head and a handle reset torsion spring are needed to realize the reset of the door handle after lifting it up to lock the door and pressing it down to open the door, it still uses a torsion spring for reset, just like the existing door handles on the market. When the user uses it, improper force of the torsion spring may cause the door handle to feel stiff or too loose when rotating. At the same time, the torsion spring may generate noise during movement, affecting the user experience. In addition, if the torsion spring is damaged during long-term use and needs to be replaced, special tools such as circlip pliers are required, which may be inconvenient for ordinary users.

[0004] In addition, existing door handles may shake during use, which may prevent users from operating smoothly, resulting in unsmooth or even difficult opening and closing of the door. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a door handle reset structure which improves the reset effect, improves the user's hand feeling and prevents the door handle from shaking, in view of the above-mentioned deficiencies in the prior art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a door handle reset structure, comprising a door handle and a base, wherein the door handle is rotatably mounted on the base through a handle head, and is characterized in that: an installation cavity is provided on the end of the base away from the door handle, and at least one group of spring rails are provided on the inner wall of the installation cavity, a reset spring is installed in the spring rail, and a linkage paddle is provided between the handle head and the reset spring, which is linked to the door handle and enables the reset spring to be compressed and moved along the spring rail.

[0007] The above-mentioned technical scheme is adopted: compared with the structure of existing door handles that use torsion springs for resetting, the utility model adopts the setting of spring rails and linkage paddles, and a reset compression spring is arranged in the spring rail. When the user turns the door handle, it can drive the linkage paddle to rotate together, thereby prompting the reset compression spring to be compressed along the spring rail in the rotation direction of the door handle. When the user releases the door handle, the force of compressing the reset compression spring disappears, and the elastic force of the compression spring pushes the linkage paddle to reset, thereby driving the door handle to reset. Preferably, two groups of spring rails are arranged, and a reset compression spring is arranged in each group of spring rails. During use, smoother and more consistent force feedback can be provided, making the operation of the door handle smoother and improving the user's feel when using it.

[0008] A further configuration of the utility model is that the linkage paddle extends toward the door handle and is provided with a pair of spring stops distributed at both ends of a return compression spring, each spring stop abuts against the two ends of the return compression spring respectively, and the linkage paddle is sleeved on the handle head through a first through hole provided in the middle.

[0009] The above technical solution adopts: by setting the spring stopper, and the two spring stoppers are respectively in contact with the two ends of the return spring, so that the user can compress the return spring no matter whether he lifts the door handle up or turns the door handle down, and when the door handle is released, the return spring can quickly return the door handle to its original position.

[0010] A further configuration of the utility model is: the handle head is provided with at least two groups of first mounting grooves along its outer wall, the linkage paddle is located in the first through hole and is provided with a first mounting block that can be plugged into the first mounting groove, the end of the handle head is provided with a second mounting groove along the circumferential direction near the linkage paddle, and a retaining spring is provided in the second mounting groove.

[0011] The above technical solution is adopted: through the setting of the first mounting groove and the first mounting block, the linkage paddle is installed on the handle head to achieve the linkage effect. At the same time, the structure is simple and convenient for the staff to assemble; the setting of the retaining spring can ensure the stable resetting of the door handle and prevent axial movement of parts.

[0012] A further configuration of the utility model is that a first ring piece and a second ring piece are provided in the installation cavity, and at least two groups of first sliding grooves are spaced apart on the inner walls of the first ring piece and the second ring piece, and when the first ring piece and the second ring piece are assembled, the first sliding grooves between the two form a spring track.

[0013] The above technical solution is adopted: by adding the first and second ring pieces in the base, and combining the two to form a spring track, the processing difficulty of the spring track is reduced. At the same time, the noise generated by the reset spring during the movement of the spring track formed by the ring pieces will be smaller, thereby improving the user experience.

[0014] A further arrangement of the utility model is: the base is provided with a second through hole for installing the handle head in the installation cavity, a plurality of groups of arc grooves are provided on the side wall of the installation cavity, a plurality of groups of arc clamping blocks are provided on the outer circumference of the first ring piece and the second ring piece corresponding to the arc grooves, and a first limit block is provided at both ends of the reset compression spring on the inner wall of the first ring piece and the second ring piece.

[0015] The above technical solution is adopted: the setting of the second through hole facilitates the assembly of the base and the door handle. At the same time, the setting of the arc groove and the arc block can ensure that the first and second ring pieces are fixed on the base to avoid the first and second ring pieces being driven to rotate when the door handle is turned, thereby affecting the resetting effect of the resetting compression spring; in addition, due to the setting of the first limit block on the inner wall of the first and second ring pieces, the reset compression spring can be initially limited when the staff performs assembly to ensure the subsequent assembly process.

[0016] A further arrangement of the utility model is: a step washer is provided on the handle head, at least two groups of first mounting grooves are provided along the outer wall of the handle head, a second mounting block which can be plugged into the first mounting groove is provided on the inner wall of the step washer, the linkage paddle is in contact with one end of the step washer away from the door handle, and the base is provided on the step washer.

[0017] The above technical solution is adopted: by setting a step washer, and a second mounting block is provided on the step washer, the step washer is plugged into the first mounting groove on the handle head through the second mounting block, and the base is sleeved on the step washer, which can prevent the door handle from shaking and make the structure more tight.
