Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figure 1-6 shown, a split lock includes a seat body 1, a cover body 2 covering the seat body 1, a receiving cavity 3 formed between the seat body 1 and the cover body 2, an abutting block 4 and a limiting block 5 provided on the seat body 1, a handle head 6 provided on the seat body 1 and rotatably arranged between the abutting block 4 and the limiting block 5, and a reset member provided in the receiving cavity 3 and configured to urge the handle head 6 to rotate and reset. The reset member is configured as a flat spring 7. One end of the flat spring 7 is placed on the handle head 6, and the other end of the flat spring 7 abuts or is placed on the abutting block 4. A convex block 8 that can abut against the abutting block 4 and the limiting block 5 is provided on the handle head 6. The surface of the convex block 8 facing the abutting block 4 is a mating surface 81. When the handle head 6 is not rotated, under the action of the flat spring 7, the mating surface 81 will fit against the abutting block 4, and a frictional force away from the self-weight direction of the handle head 6 is formed between the abutting block 4 and the mating surface 81. The surface of the abutting block 4 that fits against the convex block 8 is configured as a vertical surface 41, and the mating surface is also configured as a matching vertical surface. A stepped surface 61 is provided on the handle head 6 and located in the receiving cavity 3 and abuts against the seat body 1. A pressing plate 9 that abuts against the handle head 6 and presses the stepped surface 61 against the seat body 1 is installed in the receiving cavity 3. A clamping block 11 with an inclined surface is provided on the inner peripheral surface of the seat body 1, and an inclined block 21 that is buckled on the clamping block 11 and limited by the clamping block 11 is provided on the edge of the cover body 2. A locking hole 12 is provided on the outer peripheral surface of the seat body 1, and a locking groove 22 corresponding to the locking hole 12 is provided on the cover body 2.

[0023] By adopting the above technical solutions, the main innovation point of the present invention is to set the convex block 8 that is always in contact with the abutting block 4, so that the contact area between the handle head 6 and the abutting block 4 is increased, and the situation of slight sagging of the handle can be effectively prevented. Among them, by providing the flat spring 7, one end of the flat spring 7 is placed in the groove of the handle head 6, and the other end of the flat spring 7 can abut against the surface of the abutting block 4 away from the vertical surface 41. Specifically, this surface is arranged opposite to the vertical surface 41. In this way, when the handle head 6 is rotated to abut against the limiting block 5, a restoring force can be provided for the handle head 6, and when the handle head 6 is not rotated, due to the action of the flat spring 7, the mating surface 81 of the convex block 8 can always fit against the vertical surface 41 of the abutting block 4. Since the above two surfaces are in vertical contact, the contact area between the two in the vertical direction is increased, and the situation of slight sagging of the handle installed on the handle head 6 can be overcome.

[0024] Moreover, by providing a stepped surface 61 at the perforation in the housing through which the handle head 6 passes, the stepped surface 61 can also increase the contact area between the handle head 6 and the housing, and to a certain extent prevent the handle from sagging. And by providing a pressing plate 9, the pressing plate 9 can be fixedly installed on the mounting post in the housing, playing a role in positioning the handle head 6, so that the stepped surface 61 can be well abutted and fitted on the housing, ensuring a certain frictional force between the stepped surface 61 and the housing.

[0025] In addition, by providing a clamping block 11 and a cooperating inclined block 21, when the cover 2 is snapped and pressed into the housing, it can automatically rotate and be limited by the clamping block 11, effectively ensuring the connection stability between the cover 2 and the housing, and facilitating the installation of both sides. And with the cooperation of the locking hole 12 and the locking groove 22, the cover 2 and the base 1 can be fixedly connected by passing a fastener through.

[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, making equivalent replacements or changes, should be covered within the protection scope of the present invention.
