[0040] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, and are used only for explaining the present application, and cannot be understood as limiting the present application.

[0041] The core of the present application is to provide a universal ball fastening device and intelligent door lock accessory, which can effectively improve the locking effect of the ball head of the universal ball.

[0042] In order to enable those skilled in the art to better understand the technical solutions provided by the present application, the present application will be further described in detail below in conjunction with the drawings and specific embodiments.

[0043] Specifically, referring to Figures 1-9 The universal ball fastening device provided by the present application comprises a housing 100, a ball head 200, a locking core 300 and a fastener 400.

[0044] The housing 100 is a cylindrical structure with open ends, and has a hollow cavity inside. The two ends of the housing 100 are a large-diameter end and a small-diameter end, respectively. The diameter of the large-diameter end is larger than that of the small-diameter end.

[0045] One end of the ball head 200 is a spherical body, and the other end is provided with a first connecting part 210, which can be detachably used for connecting a component to be adjusted A. The diameter of the spherical body is smaller than that of the large-diameter end of the housing 100, and the diameter of the spherical body is larger than that of the small-diameter end. The spherical body can enter the hollow cavity from the large-diameter end of the housing 100 and be arranged in the housing 100, so that the small-diameter end of the housing 100 can limit the spherical body from coming out, and the spherical body can freely rotate in the hollow cavity of the housing 100. The first connecting part 210 extends out of the small-diameter end and is connected with the component to be adjusted A.

[0046] The locking core 300 is disposed in the hollow cavity of the housing 100 and a first end thereof is connected to the ball.

[0047] The fastener 400 is used to limit the relative movement between the locking core 300 and the ball head 200 .

[0048] The universal ball joint fastening device provided in this solution features a spherical head 200 rotatably mounted on the small-diameter end of the housing 100. The first connecting portion 210 of the ball joint 200 can extend from the small-diameter end of the housing 100 and connect to the component A to be adjusted. Adjusting the rotational direction of the ball joint 200 allows the orientation of the component A to be adjusted. Simultaneously, a locking core 300, with one end docked with the spherical head 200 and the other end mounted on the large-diameter end of the housing 100, limits relative movement between the locking core 300 and the ball joint 200 via a fastener 400. Compared to prior art methods that directly lock and limit the ball joint using a fastener, this solution effectively enhances the locking effect of the universal ball joint by adding the locking core 300.

[0049] In a specific embodiment, the first end surface of the locking core 300 is a hemispherical surface that matches the sphere. A layer of elastic pad 500 is disposed on the hemispherical surface, which fits the sphere. The elastic pad 500 can be made of an elastic material such as rubber or silicone. During the extrusion process, the elastic pad 500 deforms to achieve a tight fit with the sphere, thereby improving the locking effect of the ball head 200.

[0050] A soft, elastic pad 500 fills the gap between the ball head 200 and the fastener 400, reducing wear on the ball head 200 and ensuring the ball joint rotates freely and maintains stable positioning. Compared to conventional products, this arrangement optimizes and improves the installation and fixation of the ball head and fastener.

[0051] The elastic pad 500 is provided with a plurality of anti-skid protrusions 510 on the side in contact with the ball. The anti-skid protrusions 510 have an anti-skid effect and can be specifically circular protrusions.

[0052] The elastic pad 500 and the locking core 300 can be connected in a variety of ways. In one form, the elastic pad 500 is connected to the first end face of the locking core 300 via a snap to facilitate disassembly. The snap provided on the elastic pad 500 can be an elastic claw, and the locking core 300 is provided with a slot. The elastic pad 500 cooperates with the locking core 300, and after the elastic claw is inserted into the slot, it limits the elastic pad 500. The connection surface between the elastic pad 500 and the locking core 300 can also be a flat surface. In another form, the elastic pad 500 and the locking core 300 are bonded by glue. Of course, other methods can also be used to achieve the connection between the elastic pad 500 and the locking core 300.

[0053] In a specific embodiment, the fastener 400 is a locking pin, and the side wall of the shell 100 is provided with a socket 110 which can communicate the outside with the hollow cavity of the shell 100. Correspondingly, the side wall of the locking core 300 is provided with a clamping groove 310. When the fastener 400 and the locking core 300 are clamped, the first end of the locking core 300 can extrude the ball, and the space between the first end face of the locking core 300 and the hollow cavity of the shell 100 can limit the rotation of the ball head 200.

[0054] When the fastener 400 is a locking pin, one end of the locking pin can be inserted into the socket 110 of the shell 100, and the other end of the locking pin is provided with a handle. When the locking pin and the clamping groove 310 of the locking core 300 are clamped, the first end of the locking core 300 can extrude the ball, so that the space formed between the first end face of the locking core 300 and the hollow cavity of the shell 100 can limit the rotation of the ball head 200.

[0055] In another specific embodiment, the fastener 400 is a locking knob, and one end of the fastener 400 is provided with an external thread, and the other end of the locking knob can also be provided with a handle. The side wall of the shell 100 is provided with a socket 110 which can communicate the outside with the hollow cavity of the shell 100. The side wall of the locking core 300 is provided with an internal thread matched with the external thread. When the fastener 400 and the locking core 300 are connected through the threads, the ball head 200 can be extruded by the locking core 300 to limit the relative position of the locking core 300 and the shell 100.

[0056] Of course, the fastener 400 can also adopt other structural forms such as a clamp, for example, the relative position of the locking core 300 and the shell 100 is limited by the clamp, so that the first end face of the locking core 300 presses the ball head 200 to the small-diameter end of the shell to limit the relative movement of the locking core 300 and the ball head 200. As long as the fastener 400 has the above limiting function, it is within the scope of the present application, and will not be described here.

[0057] Further, when the fastener 400 is a locking pin, the side of the clamping groove 310 close to the ball is designed as an inclined surface, and the side surface of one end of the fastener 400 is a tapered surface, which is beneficial to the smooth rotation of the fastener 400 into the clamping groove 310 of the locking core 300. After the fastener 400 is rotated, the inclined surface of the clamping groove 310 is contacted, and a downward extrusion force is generated on the inclined surface.

[0058] In addition, the number of fasteners 400 can be one, or can be designed as multiple according to actual conditions. Figures 2-3 As shown, the number of fasteners 400 is one, and correspondingly, the socket 110 on the shell 100 and the clamping groove 310 of the locking core 300 are also one. It can also be as shown in Figure 1As shown, the number of fasteners 400 is two, and the two fasteners 400 are symmetrically arranged, and correspondingly, the number of the insertion holes 110 on the shell 100 and the clamping grooves 310 of the locking core 300 is also two, and the positions correspond to the fasteners 400 one by one.

[0059] In specific embodiments, the small-diameter end of the shell 100 is provided with an avoiding groove 120 for avoiding the first connecting part 210 of the ball head 200. The number of the avoiding grooves 120 can be multiple, and each avoiding groove 120 is arranged in the main rotating direction of the ball head 200, so that the first connecting part 210 of the ball head 200 can be avoided from interfering with the shell 100 during rotation.

[0060] In actual design process, the small-diameter end of the shell 100 can be provided as a tapered mouth, and the hollow cavity is a cylindrical cavity, and the inner wall of the shell 100 formed by the tapered mouth can prevent the ball of the ball head 200 from being taken out from the end.

[0061] In specific embodiments, the second end of the locking core 300 is provided with a boss, and the boss can abut against the end face of the large-diameter end of the shell 100, so that the locking core 300 is prevented from being completely taken out from the hollow cavity of the shell 100.

[0062] In order to facilitate disassembly and assembly, the second end face of the locking core 300 is provided with a threaded hole for connecting with the mounting component B.

[0063] In addition, the utility model also provides a kind of intelligent door lock accessory, including to be adjusted component A and the universal ball fastening device in the above specific embodiments, the first connecting part 210 of ball head 200 is connected with to be adjusted component A, one of the second end of shell 100 or locking core 300 is connected with mounting component B. Wherein, to be adjusted component A is the component that needs to adjust the angle on intelligent door lock accessory, such as charging accessory (wireless charging device) etc., mounting component B is fixed position such as wall body. When intelligent door lock accessory is applied to wireless charging device, as shown in Figure 8 and Figure 9 As shown, to be adjusted component A can be the transmitting end A1 or receiving end A2 of wireless charging device.

[0064] Obviously, the intelligent door lock accessory containing the above universal ball fastening device has the same beneficial effects, which will not be repeated here.
