Description

Technical Field

[0001] This utility model relates to the field of door handle technology, and in particular to a split-type door handle. Background Technology

[0002] Door handles are an indispensable door accessory, serving both decorative and functional purposes. They are made of various materials, including ceramic, solid wood, metal, glass, crystal, plastic, and alloy. There are many types of door handles available. They are installed in pairs on the inside and outside of the door. Door handles are usually available in two shapes: "7" and round. They are rotated by hand to release the lock and open the door.

[0003] For example, Chinese utility model patent CN222501303U discloses an adjustable door handle, which incorporates an assistive component to help the user turn the door handle. When the door handle drives the rotating shaft to rotate, it triggers an electronic control unit, which in turn starts a motor and gearbox to assist the rotating shaft, thereby reducing the force required to turn the door handle. This design greatly enhances the user experience and can be of great help to some young children and users with myasthenia gravis. However, such a structure still has the following significant drawbacks:

[0004] 1. When existing handles are used as components, they are all integrated, which makes it inconvenient and difficult to transport the handles. Improper handling may easily cause damage to the handles.

[0005] 2. Existing door locks usually have a deadbolt mechanism. The deadbolt mechanism is mainly implemented by a deadbolt knob located on the front face of the door handle or separately located on one side of the door handle. Turning the deadbolt knob will drive the linkage device inside the lock body to rotate, thereby locking the door. This type of deadbolt mechanism increases the structure of the outer surface of the door lock, especially the front visible surface, and is not suitable for minimalist style application scenarios. Summary of the Invention

[0006] This utility model aims to solve one of the technical problems existing in the prior art.

[0007] This application provides a split door handle, including a handle and a base; a drive shaft is fixedly installed on the handle, and the drive shaft has a first circular groove and a second circular groove along its height and length directions, respectively; a rotating block is rotatably installed on the base, and the rotating block has a drive groove that slides with the drive shaft; a cylindrical block that slides with the first circular groove is provided in the drive groove; a deadbolt device is provided on the base; when the drive shaft is inserted into the drive groove, the deadbolt device is aligned with / not aligned with the second circular groove, and rotating the handle can / cannot drive the drive shaft to rotate.

[0008] Furthermore, the locking device includes a locking ball and a pushing device. The transmission groove has a mounting groove along its width, in which the locking ball is rolled. The base has a pushing device that can push the locking ball in, causing it to slide within the mounting groove and transmission groove.

[0009] A limiting ring block is provided at the groove opening where the mounting groove connects to the transmission groove.

[0010] Furthermore, the pushing device includes a pushing block and a pushing spring. The base is provided with a pushing groove, and the pushing block is slidably installed in the pushing groove. One end of the pushing spring is pressed and fixed on the pushing block, and the other end is pressed and fixed on the pushing groove.

[0011] Furthermore, a limiting block is fixed on the pushing block, and a limiting groove is provided on the pushing groove to slide in cooperation with the limiting block.

[0012] Furthermore, the limiting ring block is circular, and the inner diameter of the limiting ring block is smaller than the diameter of the locking ball.

[0013] Furthermore, the handle is provided with a connecting part, and the connecting part is provided with a connecting groove, and one end of the drive shaft is fixedly installed in the connecting groove.

[0014] Furthermore, the drive shaft is a square block, and both the drive groove and the connecting groove are square grooves that match the drive shaft.

[0015] Furthermore, a cover plate is rotatably mounted on the base, which can completely cover the drive shaft.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. With the design of the handle split structure, each component can be classified and stored or transported before use, which effectively improves the convenience of storage or transportation and reduces the storage or transportation loss rate.

[0018] 2. With the addition of a deadbolt device, the deadbolt function can be achieved without relying on the structure inside the door lock. The locking ball and push device with the deadbolt function are located inside the base, which will not affect the appearance of the front visible surface of the inner handle, ensuring that the front visible surface of the inner handle has a clean appearance.

[0028] The following description, in conjunction with the accompanying drawings, details a split-type door handle provided in this application through specific embodiments and application scenarios.

[0029] Example 1:

[0030] like Figures 1 to 4As shown, this application embodiment provides a split door handle, including a handle 1 and a base 2; a drive shaft 3 is fixedly installed on the handle 1, and the drive shaft 3 is provided with a first circular groove 31 and a second circular groove 32 along its height direction and length direction, respectively; a rotating block 21 is rotatably installed on the base 2, and the rotating block 21 is provided with a drive groove 22 that slides with the drive shaft 3; a cylindrical block 23 that slides with the first circular groove 31 is provided in the drive groove 22; a deadbolt device 4 is provided on the base 2; when the drive shaft 3 is inserted into the drive groove 22, the deadbolt device 4 and the second circular groove 32 are in corresponding / non-corresponding positions, and rotating the handle 1 can / cannot drive the drive shaft 3 to rotate.

[0031] Furthermore, the locking device 4 includes a locking ball 41 and a pushing device 42. The transmission groove 22 is provided with a mounting groove 43 along its width direction. The locking ball 41 is rolled in the mounting groove 43. The base 2 is provided with a pushing device 42, which can push the locking ball 41 to slide, so that the locking ball 41 is located in the mounting groove 43 and the transmission groove 22. A limiting ring block 44 is provided at the groove opening where the mounting groove 43 and the transmission groove 22 are connected.

[0032] Furthermore, the pushing device 42 includes a pushing block 421 and a pushing spring 422. The base 2 is provided with a pushing groove 423. The pushing block 421 is slidably installed in the pushing groove 423. One end of the pushing spring 422 is pressed and fixed on the pushing block 421, and the other end is pressed and fixed on the pushing groove 423.

[0033] Furthermore, a limiting block 424 is fixed on the pushing block 421, and a limiting groove 425 is provided on the pushing groove 423 to slide in cooperation with the limiting block 424.

[0034] Furthermore, the limiting ring block 44 is circular, and the inner diameter of the limiting ring block 44 is smaller than the diameter of the locking ball 41.

[0035] In this embodiment of the application, due to the above-described structure, the base 2 is installed on the inside of the door. In the initial state, the push groove 423 is connected to the mounting groove 43, and the push block 421 and the push spring 422 can make the corresponding locking ball 41 located in the transmission groove 22 and the mounting groove 43.

[0036] During the process of inserting the drive shaft 3 into the drive groove 22, the drive shaft 3 will push a pair of locking balls 41 to slide outward, and push the corresponding push block 421 to slide synchronously, squeezing the corresponding push spring 422, until the drive shaft 3 is inserted into the bottom of the drive groove 22. At this time, the position of the locking balls 41 and the second groove 32 is corresponding / not corresponding.

[0037] When the locking ball 41 corresponds to the position of the second circular groove 32, under the action of the spring force of the push spring 422, the corresponding push block 421 and the corresponding locking ball 41 are pushed to slide inward, so that the locking ball 41 is located in the mounting groove 43 and the second circular groove 32, and the push block 421 is located in the push groove 423. At this time, rotating the handle 1 can synchronously drive the transmission shaft 3 and the rotating block 21 to rotate. The rotating block 21 cooperates with the external linkage structure to achieve unlocking.

[0038] When the locking ball 41 and the second circular groove 32 are not in the same position, the locking ball 41 is pressed against the side wall of the transmission shaft 3, and the corresponding push spring 422 and push block 421 cannot push the locking ball 41 to slide inward. At this time, the locking ball 41 is located in the mounting groove 43 and the push groove 423, the handle 1 cannot be rotated, and therefore cannot be unlocked, that is, it is currently in the reverse lock state.

[0039] A limiting block 424 is fixed on the pushing block 421, and a limiting groove 425 is provided on the pushing groove 423 to slide with the limiting block 424. The limiting block 424 and the limiting groove 425 can prevent the pushing block 421 from partially sliding out of the pushing groove 423.

[0040] A limiting ring block 44 is provided at the groove opening where the mounting groove 43 connects to the transmission groove 22. The limiting ring block 44 is circular, and the inner diameter of the limiting ring block 44 is smaller than the diameter of the locking ball 41, so as to prevent the locking ball 41 from being completely pushed out of the mounting groove 43 by the corresponding push spring 422 and the corresponding push block 421.

[0041] Example 2:

[0042] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the handle 1 is provided with a connecting part 11, the connecting part 11 is provided with a connecting groove 12, and one end of the transmission shaft 3 is fixedly installed in the connecting groove 12.

[0043] Furthermore, the drive shaft 3 is a square block, and both the drive groove 22 and the connecting groove 12 are square grooves that match the drive shaft 3.

[0044] Furthermore, a cover plate 24 is rotatably mounted on the base 2, which can completely cover the drive shaft 3.

[0045] In this embodiment of the application, due to the above-mentioned structure, the handle 1 is provided with a connecting part 11, the connecting part 11 is provided with a connecting groove 12, and the end of the transmission shaft 3 without the first circular groove 31 and the second circular groove 32 can be inserted into the connecting groove 12 and can be fixedly connected together by welding.

[0046] The drive shaft 3 is a square block, and both the connecting groove 12 and the drive groove 22 are square grooves, so that rotating the handle can drive the drive shaft 3 to rotate synchronously, and rotating the drive shaft 3 can drive the rotating block 21 to rotate synchronously.

[0047] A cover plate 24 is rotatably mounted on the base 2. Before installation, the cover plate 24 can completely cover the drive shaft 3 to prevent dust and debris from entering during storage or transportation.
