The door lock handle, also called handle, can play the effect of making things convenient for the user to open the door and lock the door. The door lock handle is usually connected with an elastic structure, and through the elastic structure in the door lock, the handle can automatically return to a horizontal state after door opening or door locking is completed. That is, the handle can be maintained in a normal horizontal state after the handle loses the influence of external force. However, after the door lock is used for a long time, the handle is shaken and sagged due to fatigue of the internal elastic structure. And the handle is rocked and sagged to influence the normal use experience of the user.

At present, the design scheme of preventing the door lock handle from sagging generally selects torsion springs, middle frame limit posts and handle clutch piece reversing screws to be matched. The handle drives the reversing screw after being pressed down/lifted up, and then drives the torsion spring. After the door opening or locking action is completed, the handle can be reset by the reverse moment generated by the torsion spring. However, the scheme requires torsion springs, middle frame limiting columns and handle clutch member transposition screws to be in a close fit state. In actual situations, because of the torsion spring, the middle frame limit column structural member has tolerance and can not keep a close fit state, and therefore the handle shaking and sagging phenomena are easy to occur. Simultaneously, after the door lock is used for a long time, the torsional spring can also be tired, and the phenomenon of shaking and sagging of the handle can be caused. And the handle appears rocking and sagging, can influence user's use experience. In addition, adjusting the torsion spring also wastes a lot of manpower efficiency.

In order to ensure that the handle is in a stable horizontal state during use, some embodiments of the present utility model provide a handle arrangement. The clutch part matched with the handle in the handle device keeps the handle in a horizontal state by the acting force exerted by the acting part. Wherein, the acting piece is movably connected with the shell of the handle device through an elastic structure. And, the acting member takes the form of an elastic structure connected from edge portions of both sides. In this way, the acting element can be made to exert a force on the clutch element from the direction of movement. So that the acting member can stably exert a force on the clutch member for a long period of time to ensure that the handle is stably maintained in a horizontal state.

The structure of the handle device according to some embodiments of the present utility model will be described with reference to fig. 1 to 3.

As shown in fig. 1 to 3, some embodiments of the present utility model provide a handle device including a housing 10, a handle 11, a clutch member 12, and an acting member 13. The housing 10 is provided with mounting holes 103 extending from the inner side 101 to the outer side 102. The handle 11 is placed on the outside 102 of the housing 10. The clutch member 12 is disposed on the inner side 101 of the housing 10, one of the clutch member 12 and the handle 11 is connected to the other through the mounting hole 103, and the clutch member 12 is rotatable with the handle 11 around the axial direction of the mounting hole 103. The acting member 13 is movably provided on the inner side 101 of the housing 10 in the radial direction of the mounting hole 103, and the edge portions 131 of the acting member 13 on both sides of the mounting hole 103 are applied with elastic force, and the intermediate portion 132 of the acting member 13 between the edge portions 131 on both sides abuts against the clutch member 12 to hold the handle 11 in a horizontal state.

The housing 10 serves in the handle device to provide a mounting base for other components, the housing 10 being fixable in the door leaf at the location of the locking hole. A cavity is formed in the housing 10, and the cavity of the housing 10 can be used for installing components such as a lock tongue. The mounting hole 103 is a hole formed in the housing 10 for mounting the handle 11, and the mounting hole 103 penetrates from the inner side 101 to the outer side 102 of the housing 10. The inner side 101 of the housing 10, i.e. the side of the housing 10 where the cavity is formed, and the outer side 102 of the housing 10, i.e. the side of the door leaf when the housing 10 is mounted.

The handle 11 is mounted on the outside 102 of the housing 10. A portion of the handle 11 is disposed opposite the mounting hole 103 of the housing 10, and the handle 11 may be provided in a bent shape or a lug-attached spherical shape for a user to grip. When the user rotates the handle 11, the handle 11 can rotate around the axial direction of the mounting hole 103 relative to the housing 10, so as to drive the lock tongue to realize door opening or conveniently lock the door, and the lock tongue enters the lock hole of the door frame.

The clutch member 12 is a component for realizing the function of preventing the peep hole from unlocking in the handle device, a button can be arranged on the handle 11, and the clutch member 12 and the lock tongue can be in a matched state when the button is pressed, so that the lock tongue is driven to move in the process of rotating the handle 11. In practice, the clutch member 12 may be fixed to the handle 11 to perform the function of mounting the handle 11. The clutch member 12 can rotate in synchronization with the handle 11 in the axial direction around the mounting hole 103.

The acting member 13 is used to apply a force to the clutch member 12 so that the handle 11 can be placed in a horizontal state when the handle 11 is not affected by an external force. The acting element 13 is connected elastically to the housing 10 during installation, so that the acting element 13 can exert a force on the clutch element 12 under the influence of an elastic force. So that the clutch member 12 can be kept unchanged under the influence of the force from the acting member 13 when the handle 11 is not influenced by the force from the outside, so that the handle 11 is kept in a horizontal state.

Some embodiments of the present utility model provide a handle device, including a handle 11 and a clutch member 12, where the handle 11 is connected to the clutch member 12 and drives the clutch member 12 to rotate together around an axial direction of the mounting hole 103. The clutch member 12 receives a force from the acting member 13. The acting member 13 is movable in the radial direction of the mounting hole 103 and is applied with an elastic force, so that the acting member 13 can be stably held against the clutch member 12 for a long period of time while keeping the clutch member 12 unchanged. So that the handle 11 can be stably maintained in a horizontal state without being affected by external force. That is, by applying the urging force of the urging member 13 to the clutch member 12 from the moving direction, it is possible to ensure that the handle 11 is stably maintained in the horizontal state during use.

In addition, the middle part 132 of the acting piece 13 is abutted against the clutch piece 12, so that the acting force born by the two edge parts 131 of the acting piece 13 is relatively uniform, the resistance born by the clutch piece 12 when the handle 11 is rotated is reduced, and the rotation process of the handle 11 is relatively stable.

The mating portion 122 may be mated with the acting element 13 in a surface contact manner, that is, the mating surface 1221 of the mating portion 122 is disposed in parallel with the axial direction of the mounting hole 103. Thereby facilitating the abutment of the intermediate portion 132 of the acting element 13 against the mating surface 1221 in a surface contact. In actual situations, the mating surface 1221 may be planar or curved. In addition, the middle portion 132 of the acting element 13 may also abut against the mating surface 1221 in a line contact manner, and also may serve to limit the free rotation of the clutch element 12.

As shown in fig. 2, in some embodiments, the mating surface 1221 may be projected on the housing 10 in a racetrack shape, and the middle portion 132 of the acting element 13 abuts against the flat portion of the mating surface 1221 when the handle 11 is in the horizontal state.

In this way, when the middle portion 132 of the acting member 13 abuts against the straight portion of the mating surface 1221, the clutch member 12 can be kept unchanged, and the clutch member 12 is restricted from rotating randomly, so that the handle 11 is kept in a horizontal state when no external force is applied. When the user rotates the handle 11, the handle 11 drives the clutch member 12 to rotate, so that the curved portion of the mating surface 1221 contacts with the abutting member, thereby facilitating the user to smoothly rotate the handle 11.

In some embodiments of the present utility model, the acting member 13 may include a supporting plate 133 and a post 134 located at two opposite side edges of the supporting plate 133, where the supporting plate 133 is supported on the mating surface 1221, one end of the post 134 is connected to the supporting plate 133, the other end of the post 134 is sleeved with the elastic member 14, and the end of the elastic member 14 away from the post 134 is supported on the housing 10.

The supporting plate 133 is a portion of the acting member 13 that supports against the mating surface 1221 of the clutch member 12, and the supporting plate 133 is connected to the column 134 to form a whole. The end of the post 134 is connected to the housing 10 by the elastic member 14, and the elastic member 14 can apply an elastic force to the whole of the post 134 and the holding plate 133, so that the holding plate 133 is stably held against the clutch member 12.

In practical situations, the elastic member 14 may be a telescopic spring, a disc spring or a spring sheet. At the opposite side edges of the abutment plate 133, elastic members 14 are provided to achieve elastic connection between the housing 10 and the cylinder 134 of the acting member 13, so that the acting member 13 can stably apply a force to the clutch member 12. By adopting the form that the acting piece 13 abuts against the clutch piece 12, the acting piece 13 can apply acting force to the clutch piece 12 along the moving direction, the matching tightness degree between the elastic piece 14 and the acting piece 13 and between the elastic piece 14 and the shell 10 can be reduced, and the shaking and sagging phenomena of the handle 11 caused by the fact that the matching clearance exists between the elastic piece 14 and the acting piece 13 and between the elastic piece 14 and the shell 10 in the directions except the elastic force can be avoided.

As shown in fig. 3, in some embodiments, the handle device may further include a cover 15, where the inner side 101 of the housing 10 is provided with a cylindrical groove 104, and the elastic member 14 and a part of the column 134 are disposed in the cylindrical groove 104, and the cover 15 is detachably connected to the housing 10 and covers the elastic member 14 and the part of the column 134.
