[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but only represents selected embodiments of the present invention.

[0023] Example 1

[0024] Reference Figure 1 The present invention discloses a combined ball locking structure, including a base 200 and a ball head connecting rod 100 rotatably mounted on the base 200, a push rod 300 is slidably arranged in the ball head connecting rod 100, one end of the push rod 300 extends to the end of the ball head connecting rod 100 mounted on the base 200, and when the push rod 300 slides toward the base 200, a convex portion can be formed on the surface of the end of the ball head connecting rod 100 mounted on the base 200, thereby locking the relative position of the ball head connecting rod 100 and the base 200.

[0025] Specifically, the ball head connecting rod 100 includes a mounting ball head 102 and a connecting rod 101 fixed to the mounting ball head 102. A spherical mounting cavity 203 adapted to the mounting ball head 102 is concavely arranged on the base 200. The dimensions between the two are transitional or clearance matched so that the ball head connecting rod 100 can rotate flexibly.

[0026] In this embodiment, through holes are directly provided on the connecting rod 101 and the mounting ball head 102, and the top rod 300 is slidably inserted therein, so that the top rod 300 can pass through the mounting ball head 102 and form a convex portion on the surface of the mounting ball head 102. Since the spherical mounting cavity 203 is adapted to the mounting ball head 102, when the top rod 300 is extended, the friction between the mounting ball head 102 and the base 200 is increased, thereby achieving locking.

[0027] Obviously, the combined ball locking structure in this embodiment only needs to control the sliding of the push rod 300 to achieve the switching of the ball head connecting rod 100 between the adjustment mode and the locking mode.

[0028] In order to realize the control of the push rod 300, the other end of the push rod 300 passes through the end of the ball head connecting rod 100 away from the base 200, and the ball head connecting rod 100 is preset with a connection structure 103 at the end. The connection structure 103 can be set to connect other supporting mechanisms, such as a tripod, a hand-held rod, a tripod, a quick-release wrench seat, etc. during actual use, and when connecting other supporting mechanisms, the end of the push rod 300 is supported by other supporting mechanisms, and when fully connected, the push rod 300 slides to a relative position where the ball head connecting rod 100 and the base 200 are completely locked.

[0029] like Figure 3 As shown in the figure, as a first preferred embodiment of the connection structure 103, the connection structure 103 is configured as a threaded mounting hole coaxially distributed with the push rod 300, the threaded mounting hole is opened at the end of the ball head connecting rod 100 away from the base 200, and the end of the push rod 300 extends into the threaded mounting hole. In this way, when other supporting mechanisms are threadedly connected to the threaded mounting hole, the push rod 300 can be gradually pushed during the screwing process, and the other end of the push rod 300 is controlled to extend out of the surface of the mounting ball head 102 until it is completely locked.

[0030] As a second preferred embodiment of the connection structure 103, the connection structure 103 is provided with a threaded connection sleeve, which is clamped on the end of the ball head connecting rod 100 away from the base 200, and the end of the top rod 300 is inserted into the threaded connection sleeve. A concave-convex structure can be provided between the connecting rod 101 and the threaded connection sleeve to prevent it from falling off. In this way, compared with the first preferred embodiment, it is not necessary to process a hole at the end of the connecting rod 101, which is conducive to improving production efficiency and production quality.

[0031] Of course, the connection structure 103 may also be configured as other snap-fit ​​or buckle-fit structures.

[0032] In summary, the conventional ball head is locked from the outside to the inside, while the combined ball locking structure of the present invention is locked by forming a convex portion on the ball head connecting rod 100, which is locked from the inside to the outside. The different implementation methods can not only realize the flexible adjustment of the ball head connecting rod 100, but also realize locking and fixing at any position, and have a longer service life and strong practicality. A connecting structure 103 is further provided, so that the base 200 and the ball head connecting rod 100 are locked and fixed while the connecting structure 103 is connected to the head or other supporting mechanism, which is simpler and more practical than the installation method of the traditional structure.

[0033] In addition, the present embodiment further provides a clamping device, which includes a clamping body, on which the combined ball locking structure of the above structure is arranged. Specifically, the clamping body is provided with a supporting structure and a clamping structure, the clamping structure is arranged on a base 200, and the supporting structure is connected to the ball head connecting rod 100 through a connecting structure 103, so that angle adjustment can be achieved through the combined ball locking structure during use.

[0034] Obviously, during use, it is only necessary to first adjust the angle between the base 200 and the ball head connecting rod 100, and then connect and fix the supporting structure to the ball head connecting rod 100 to achieve angle fixing. By separating the two or loosening the connection between the two appropriately, the angle between the ball head connecting rod 100 and the base 200 can be flexibly adjusted. The adjustment is convenient, flexible and practical.

[0035] Example 2

[0036] This embodiment is based on the embodiment 1, except that Figure 2 and Figure 3 As shown, in this embodiment, a locking portion 301 is provided at one end of the ball head connecting rod 100 installed on the base 200 corresponding to the push rod 300, and the locking portion 301 can be convexed outward to form a convex portion under the action of the push rod 300 when the push rod 300 slides toward the base 200. Specifically, the push rod 300 is inserted into the connecting rod 101, and a mounting hole 104 is provided on the mounting ball head 102 corresponding to the push rod 300, and the locking portion 301 is slidably installed in the mounting hole 104, and the outer surface of the locking portion 301 is adapted to the mounting ball head 102 to form a complete spherical surface with it when installed in the mounting hole 104, and is partially pushed out when the push rod 300 slides toward the base 200, thereby achieving locking.

[0037] like Figure 2 and Figure 3 As shown, in this embodiment, only one locking portion 301 is provided on the mounting ball head 102. The size of the locking portion 301 is larger than the top rod 300, so that the contact area with the spherical mounting cavity can be increased, which is conducive to locking.

[0038] Of course, in the actual production process, multiple locking parts 301 can also be provided on the mounting ball head 102, so that multiple convex parts and multiple force application points can be formed on the surface of the mounting ball head 102 to facilitate locking. The sliding control can cooperate with the push rod 300 through the wedge surface structure to achieve the push rod 300 pushing multiple locking parts 300 to extend at the same time.

[0039] In order to ensure the sliding and locking effects, the locking portion 301 is preferably made of a hard material so that it has a certain strength.

[0040] In addition, it should be noted that in the actual production process, the size of the locking portion 301 needs to be smaller than the size of the mounting ball head 102. And when multiple locking portions 301 are provided, their arrangement positions meet the requirements of not being exposed or falling out within the rotatable range of the mounting ball head 102.

[0041] Example 3

[0042] This embodiment is based on the embodiment 1, except that the combined ball locking structure in this embodiment is further provided with a support rod, which is detachably connected to the ball head connecting rod 100 through the connecting structure 103 and pushes the push rod 300 to slide at the same time. In this way, the push rod 300 is pushed by the support rod.

[0043] Example 4

[0044] This embodiment is based on the embodiment 1, except that: Figure 4 As shown, in this embodiment, a boss is provided on the surface of the base 200, and a spherical installation cavity 203 adapted to the installation ball head 102 is provided inwardly on the boss, so that a circle of ribs 202 protruding relative to the surface of the base 200 is formed at the edge of the spherical installation cavity 203, and a plurality of adjustment grooves 201 are provided on the ribs 202, and the width of the adjustment grooves 201 is adapted to the connecting rod 101. For example, two adjustment grooves 201 can be provided, and the central angle between the two is set to 90°. In this way, during the adjustment process, they can correspond to the horizontal and vertical directions respectively, and by inserting the connecting rod 101 into the adjustment groove 201 and then fixing it, it is conducive to ensuring the stability of the angle.

[0045] Example 5

[0046] This embodiment is based on the embodiment 1, except that Figure 4 As shown, the base 200 in this embodiment is provided with a locking bolt 400 corresponding to one end of the ball head connecting rod 100 installed on the base 200 . The locking bolt 400 is rotatably installed on the base 200 and can be screwed into and abut against one end of the ball head connecting rod 100 installed on the base 200 .

[0047] Such an arrangement allows the mounting ball head 102 to be subjected to multi-directional forces, so that multiple force points are formed between the mounting ball head 102 and the spherical mounting cavity 203 , which is beneficial for strengthening the angle fixation between the ball head connecting rod 100 and the base 200 .

[0048] The above embodiments are only preferred embodiments of the present invention, and the present invention may also have other implementation schemes, such as reasonably combining the above multiple embodiments. Those skilled in the art may also make equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope set by the claims of this application.
