Technical Field
[0001] The utility model relates to the technical field of door locks. Specifically, the utility model relates to a handle assembly and a door lock. Background Art
[0002] As the name implies, a door lock is a device used to lock a door to prevent others from opening it. There are many classifications of door locks, and the requirements for door locks vary in different occasions. Ordinary families generally use anti-theft door locks, which are highly secure and relatively inexpensive. Door locks can be classified into spherical door locks, three-rod handle locks, mortise handle locks, glass door locks, etc. according to different lock-making technologies and applications. The commonly used handle lock is generally composed of structures such as a housing, a handle, a lock core, and a lock core seat, and is usually opened and closed by rotating the handle.
[0003] However, when assembling the door lock rotating shaft and the handle at present, the rotating shaft is fixed at the front end of the handle head, and the other end of the rotating shaft is inserted into the handle without additional fixation. There is a gap between the end of the rotating shaft and the handle. When the handle rotates, it is easy to cause the handle of the handle to loosen relative to the rotating shaft, resulting in a "void", which also affects the feel of opening / closing the door and the user experience.

[0028] Please refer to Figures 1 to 5 , the present utility model relates to a handle assembly 100, which is applicable to a door lock (such as a minimalist door lock, see Figure 6 ), and is sleeved on the part where the door lock rotating shaft passes through the door lock cylinder, and is used to rotatably drive the rotating shaft 200 to rotate, so as to make the lock tongue in the door lock cylinder 300 stretch and retract, realizing closing or opening the door.
[0029] The handle assembly 100 includes a handle body 10 and a bushing. The handle body 10 includes a handle head 11 and a handle connected to one end of the handle head 11. An accommodation cavity is provided in the handle head 11. The bushing is arranged in the accommodation cavity and wraps the rotating shaft 200 when the handle body 10 and the rotating shaft 200 are assembled, and is in tight fit with the rotating shaft 200 and the handle body 10.
[0030] The beneficial effects brought by the technical solution provided by the present utility model are as follows: In the handle assembly 100 of the present utility model, by arranging a bushing in the handle body 10, the bushing wraps the rotating shaft 200 and is in tight fit between the handle body 10 and the rotating shaft 200, the gap between the rotating shaft 200 and the handle body 10 can be eliminated, thus avoiding the relative loosening problem between the rotating shaft 200 and the handle body 10 and improving the user experience.
[0031] In one implementation manner, the accommodation cavity is sequentially provided with a fixed cavity 111 and a loosening prevention cavity 112 from the end surface of the handle head 11 away from the handle inward. The loosening prevention cavity 112 is smaller than the fixed cavity 111, and is adjacent to the fixed cavity 111 and communicates with the fixed cavity 111.
[0032] The bushing includes an outer fixing block 21 and an inner cushion block 22. The outer fixing block 21 is embedded in the fixed cavity 111 and is used to fix the handle head 11 and the rotating shaft 200. The inner cushion block 22 is embedded in the loosening prevention cavity 112 and is used to wrap the part where the rotating shaft 200 passes through the outer fixing block 21. Among them, the inner cushion block 22 is made of elastic plastic, so that it can be elastically matched with the handle body 10 and the rotating shaft 200, reducing the gap between the rotating shaft 200 and the handle body 10.
[0033] In one embodiment, the outer fixing block 21 is provided with a first rotating shaft hole 210 and a fixing block fixing hole 211 that both penetrate through the two end faces. The first rotating shaft hole 210 is for the rotating shaft 200 to pass through. A plurality of fixing block fixing holes 211 are provided around the first rotating shaft hole 210. Corresponding to the fixing block fixing holes 211 at the bottom of the fixing cavity 111, there are fixing threaded holes 113 for screws to pass through the fixing block fixing holes 211 and connect to the fixing threaded holes 113 to fix the outer fixing block 21 in the fixing cavity 111 of the handle head 11.
[0034] In one embodiment, a first relief notch 213 is formed at the top end of the outer fixing block 21. The first relief notch 213 is located at one end of the outer fixing block 21 close to the inner cushion block 22 and communicates with the first rotating shaft hole 210. The first relief notch 213 is for making way for the push button of the slidable push rod on the rotating shaft 200 to ensure the normal movement of the push button.
[0035] In one embodiment, the outer fixing block 21 is provided with a first rotating shaft hole 210 and a rotating shaft fixing hole 212. The first rotating shaft hole 210 penetrates through the two end faces of the outer fixing block 21. The rotating shaft fixing hole 212 is formed on the bottom side of the outer fixing block 21 and communicates with the first rotating shaft hole 210 for passing a screw to realize the fastening of the rotating shaft 200 and the outer fixing block 21.
[0036] In one embodiment, the handle assembly 100 further includes a rotating washer 23. The rotating washer 23 is attached to the end face of the handle head 11 away from the handle. An installation boss 214 is provided at one end of the outer fixing block 21 away from the inner cushion block 22. The rotating washer 23 is sleeved on the outer periphery of the installation boss 214.
[0037] In one embodiment, one end of the inner cushion block 22 abuts against the outer fixing block 21, and the other end of the inner cushion block 22 abuts against the inner side face of the anti-loosening cavity 112 at the end away from the fixing cavity 111, so that the inner cushion block 22 covers the entire anti-loosening cavity 112, thereby completely wrapping the rotating shaft 200.
[0038] In one embodiment, the inner cushion block 22 is provided with a second rotating shaft hole 220, a second relief notch 222 and a relief hole 221. The second rotating shaft hole 220 penetrates through both ends of the inner cushion block 22 in the length direction. The second relief notch 222 and the relief hole 221 are provided on a pair of opposite side faces of the inner cushion block 22 and both communicate with the second rotating shaft hole 220. The second relief notch and the relief hole are for making way for other components installed on the handle body.
[0039] By providing a first relief notch 213 on the outer fixing block 21 and second relief notches 222 and relief holes 221 on two opposite side surfaces of the inner cushion block 22, the universality of the outer fixing block 21 and the inner cushion block 22 on the inner and outer handles can be achieved, reducing the manufacturing cost of the lock.
[0040] During assembly, first, the outer fixing block 21 is sleeved on the outer periphery of the rotating shaft 200, and screws are passed through the fixing holes 211 of the fixing block to be fastened with the preset threaded holes on the rotating shaft 200. The inner cushion block 22 is sleeved on the part of the rotating shaft 200 that passes through the first rotating shaft hole 210. Then, the inner cushion block 22 is inserted into the anti-loosening cavity 112 along the fixing cavity 111, and the outer fixing block 21 is placed into the fixing cavity 111 of the handle body 10. The outer fixing block 21 is fastened to the handle body 10 with screws, thus completing the assembly of the handle assembly 100 and the rotating shaft 200.
[0041] The present utility model further provides a door lock, including a lock core 300, a rotating shaft 200, and the above-mentioned handle. The rotating shaft 200 passes through the lock core 300 and is inserted into the handle body 10 and is used to drive the handle to rotate to make the lock tongue of the lock core 300 extend and retract. The bushing is arranged between the rotating shaft 200 and the handle body 10. Since the door lock has the above-mentioned handle assembly, it has its beneficial effects, which will not be elaborated here.
