DETAILED DESCRIPTION

[0018] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The preferred embodiments of the present application will be described in detail with reference to the drawings.

[0019] The joint mechanism 100 provided by the embodiments of the present application includes a base 1, a connecting seat 2, and an adjusting rod 3. Figures 1 to 6 As shown in the drawings, the base 1 is provided with two mounting arms 11 and a connecting piece 13, the two mounting arms 11 are oppositely arranged, and the accommodating space 12 is defined between the two mounting arms 11, and the connecting piece 13 is used for connecting a main body; the connecting seat 2 includes a first joint 21 and a second joint 22 for connecting accessories, the first joint 21 and the second joint 22 are respectively located at two ends of the connecting seat 2, and the connecting seat 2 is arranged in the accommodating space 12 and is rotationally connected with the mounting arm 11, so that at least one of the first joint 21 and the second joint 22 is exposed outside the accommodating space 12; the adjusting rod 3 is arranged through the two mounting arms 11 and the connecting seat 2, so as to adjust the clamping force between the two mounting arms 11, thereby clamping or releasing the connecting seat 2.

[0020] Specifically, the base 1 is provided with two mounting arms 11 and a connecting piece 13, and the connecting piece 13 can be used for connecting a main body, so as to mount the joint mechanism 100 on the main body. It should be noted that the connecting piece 13 can be a plug rod, a screw rod, etc., as long as it can realize the connection between the base 1 and the main body, and the connecting piece 13 is not specifically limited here.

[0021] The connecting seat 2 includes a first joint 21 and a second joint 22, the first joint 21 and the second joint 22 are respectively located at two ends of the connecting seat 2, and the first joint 21 and the second joint 22 can be used for connecting different accessories, so as to realize the connection between the accessories and the main body through the cooperation of the first joint 21, the second joint 22, and the connecting piece 13 of the joint mechanism 100. And the connecting seat 2 can expand the joint type of the joint mechanism 100 by arranging the first joint 21 and the second joint 22, thereby increasing the versatility of the joint mechanism 100.

[0022] In addition, the two mounting arms 11 are oppositely arranged, and a receiving space 12 is defined between the two mounting arms 11, the connecting seat 2 is arranged in the receiving space 12 and rotationally connected with the mounting arms, so that at least one of the first joint 21 and the second joint 22 can be exposed outside the receiving space 12 (see Figure 1 , Figure 4 and Figure 6 ) by rotating the connecting seat 2, so as to conveniently switch out the joint matched with the accessory, so that the user can connect different accessories as needed, so that the replacement operation of the accessory is convenient and efficient, effectively avoiding the defect that the entire joint mechanism 100 needs to be replaced when the accessory needs to be replaced in the prior art, and compared with the prior art, the first joint 21 and the second joint 22 can also connect two accessories at the same time, expand the use scene of the joint mechanism 100. Exemplarily, when the joint mechanism 100 is applied to a shooting support and is in an environment with insufficient light, the joint mechanism 100 can connect a clamping mechanism to fix a shooting device, and the second joint 22 can connect a light supplementing device to cooperate with the shooting device to supplement light.

[0023] The adjusting rod 3 penetrates the two mounting arms 11 and the connecting seat 2, and can be used to adjust the clamping force between the two mounting arms 11 to clamp or loosen the connecting seat 2, so as to lock or unlock the connecting seat 2, realize positioning control of the connecting seat 2, and ensure the stability and reliability of the first joint 21 and the second joint 22 during use.

[0024] Further, as a specific embodiment in some embodiments of the present application, as shown in Figures 1 to 6 , the side walls of the two mounting arms 11 are each provided with a switching groove 111, and the two sides of the connecting seat 2 are each provided with a limiting block 23, the limiting block 23 is accommodated in the switching groove 111, and the limiting block 23 can rotate along the groove wall of the switching groove 111 and can slide along the groove wall of the switching groove 111 in the axial direction perpendicular to the adjusting rod 3.

[0025] Specifically, the side walls of the two mounting arms 11 are each provided with a switching groove 111, and the two sides of the connecting seat 2 are each provided with a limiting block 23, the limiting block 23 is accommodated in the switching groove 111, so that the connecting seat 2 can be arranged between the two mounting arms 11. And the limiting block 23 can rotate along the groove wall of the switching groove 111, and the limiting block 23 can slide along the groove wall of the switching groove 111 in the axial direction perpendicular to the adjusting rod 3, so that the connecting seat 2 can be slid up and down relative to the mounting arms 11 while being rotationally connected with the mounting arms 11, thereby increasing the adjusting range and flexibility of the connecting seat 2, so that the user can adjust the position of at least one of the first joint 21 and the second joint 22 exposed outside the receiving space 12 as needed.

[0026] Further, it is understandable that when the limiting block 23 can only rotate along the groove wall of the switching groove 111, in order to ensure that the first joint 21 and the second joint 22 can be switched to the vertical direction and exposed outside the accommodation space 12 after rotation, the distance between the first joint 21 and the second joint 22 and the adjusting rod 3 must be equal. However, by implementing the embodiment, the limiting block 23 can not only rotate along the groove wall of the switching groove 111, but also slide along the groove wall of the switching groove 111 in a direction perpendicular to the axial direction of the adjusting rod 3. Therefore, even if the distance between the first joint 21 and the second joint 22 and the adjusting rod 3 is not equal, as long as the connecting seat 2 is adjusted to slide up and down relative to the mounting arm 11, it can be ensured that at least one of the first joint 21 and the second joint 22 is switched to the vertical direction and exposed outside the accommodation space 12, so that the designer can avoid the constraint that the distance between the first joint 21 and the second joint 22 and the adjusting rod 3 must be equal when designing the joint mechanism 100, so that the designer can flexibly adjust the size and shape of the joint mechanism 100 according to actual needs and application scenarios, realize the optimization of the overall design of the joint mechanism 100, and reduce the design difficulty.

[0027] Further, as shown in Figure 2 , Figure 3 and Figure 5 , the first joint 21 is provided with a insertion hole 24, which penetrates the first joint 21 and is correspondingly arranged with the switching groove 111, so that the adjusting rod 3 can pass through the insertion hole 24 along the switching groove 111 of one of the mounting arms 11 and be inserted into the switching groove 111 of the other mounting arm 11.

[0028] Specifically, the insertion hole 24 penetrates the first joint 21 and is correspondingly arranged with the switching groove 111, which can ensure that the adjusting rod 3 can pass through the insertion hole 24 along the switching groove 111 of one of the mounting arms 11, be connected to the first joint 21, and be inserted into the switching groove 111 of the other mounting arm 11, so that the adjusting rod 3 can adjust the clamping force between the two mounting arms 11, thereby clamping or releasing the connecting seat 2.

[0029] Further, as shown in Figure 2 , Figure 3 and Figure 5 , the end of the first joint 21 away from the second joint 22 is provided with a plurality of insertion pieces 211, which are arranged at intervals in the axial direction of the adjusting rod 3 to define an insertion space 2111, the insertion space 2111 is in communication with the insertion hole 24, so that when the adjusting rod 3 passes through the insertion hole 24, the insertion piece 211 and the accessory joint inserted into the insertion space 2111 can be connected in series, and the second joint 22 is a screw and is connected to the other end of the first joint 21.

[0030] Specifically, the first joint 21 is provided with a plurality of insertion pieces 211 at one end away from the second joint 22, and the plurality of insertion pieces 211 are arranged at intervals in the axial direction of the adjusting rod 3, so that an insertion space 2111 can be defined between any two adjacent insertion pieces 211. The insertion space 2111 is in communication with the insertion hole 24, so that when the adjusting rod 3 passes through the insertion hole 24, the accessory joint inserted into the insertion space 2111 can be connected in series with the insertion pieces 211, so that the adjusting rod 3 can be used to fix the accessory joint while locking the connecting seat 2, and the accessory joint can be stably locked in the insertion space 2111, thereby ensuring the stability of the connection between the accessory and the first joint 21. In addition, the second joint 22 is a screw, and the second joint 22 is connected to the other end of the first joint 21, so that the accessory joint can be connected to the second joint 22 by screw connection.

[0031] It is worth mentioning that, in order to improve the strength of the screw connection of the second joint 22 and avoid damage to the second joint 22, the second joint 22 is made of metal material. The first joint 21 is made of plastic material, and the first joint 21 and the second joint 22 are integrally formed by injection molding, so that the first joint 21 and the second joint 22 can be efficiently and stably connected, thereby improving production efficiency and production quality.

[0032] Further, as a specific embodiment of some embodiments of the present application, Figure 2 , Figure 3 and Figure 5 as shown, the adjusting rod 3 is arranged in the switching groove 111 away from the base 1, and abuts against one end of the insertion hole 24 away from the second joint 22, and the limiting block 23 is arranged at the edge of the other end of the insertion hole 24 and abuts against the other end of the switching groove 111.

[0033] Specifically, the adjusting rod 3 is arranged in the switching groove 111 away from the base 1, i.e. the adjusting rod 3 is connected to one end (i.e. the free end) of the two mounting arms 11 away from the base 1. Compared with other positions, arranging the adjusting rod 3 in the switching groove 111 away from the base 1 can minimize the resistance of the two mounting arms 11 to the adjusting rod 3, so that the adjusting rod 3 can more easily tighten the two mounting arms 11, thereby reducing the operation difficulty of the adjusting rod 3, and the user only needs to exert a small force to adjust the adjusting rod 3, so that the two mounting arms 11 can tightly clamp and fix the connecting seat 2. In addition, the adjusting rod 3 abuts against one end of the insertion hole 24 away from the second joint 22, and the limiting block 23 is arranged at the edge of the other end of the insertion hole 24 and abuts against the other end of the switching groove 111, so that the rotation of the connecting seat 2 relative to the switching groove 111 can be limited, so as to cooperate with the clamping force between the two mounting arms 11 and the connecting seat 2, thereby more stably locking the connecting seat 2.

[0034] Further, as a specific embodiment of some embodiments of the present application, Figure 2 ,Figure 3 and Figure 5 As shown in

[0035] Specifically, the adjusting rod 3 and the end wall of the switching groove 111 away from the base 1 define a limiting space 1111, so that when the limiting block 23 moves into the limiting space 1111, the limiting block 23 can be limited between the adjusting rod 3 and the end wall of the switching groove 111, and the adjusting rod 3 can abut the end of the insertion hole 24 close to the second joint 22, so as to limit the sliding of the limiting block 23 along the groove wall of the switching groove 111, cooperate with the clamping force between the two mounting arms 11, and more stably lock the connecting seat 2.

[0036] Further, as a specific embodiment of some embodiments of the present application, Figure 2 , Figure 3 and Figure 5 As shown in

[0037] By implementing the present embodiment, the mounting arm 11 is provided with a mounting hole 112, which communicates with the end of the switching groove 111 away from the base 1, so that the mounting hole 112 and the switching groove 111 can form a continuous channel to facilitate the installation of the adjusting rod 3. One end of the adjusting rod 3 is provided with an operating portion 31, and the other end is provided with a threaded portion 32. One of the two mounting holes 112 is provided with a nut 4, and the operating portion 31 is exposed outside the other mounting hole 112. The threaded portion 32 is detachably connected with the nut 4. Thus, when the user rotates the operating portion 31, the threaded portion 32 can be screwed into or out of the nut 4, thereby adjusting the distance between the two mounting arms 11 and realizing the adjustment of the clamping force between the two mounting arms 11, so that the two mounting arms 11 can clamp or release the connecting seat 2. In addition, the threaded portion 32 and the nut 4 can realize the detachable connection between the adjusting rod 3 and the two mounting arms 11 and the connecting seat 2, so that by disassembling the adjusting rod 3, the two mounting arms 11 can clamp or release the connecting seat 2, and the accessories are inserted into the insertion space and fixed by the adjusting rod 3, or the accessories are separated from the insertion space 2111, and the first joint 21 is disassembled.

[0038] More specifically, as Figure 2 , Figure 3 andFigure 5 As shown, the mounting arm 11 provided with the nut 4 is provided with a boss 113 on the side away from the switching groove 111, the mounting hole 112 penetrates the boss 113 and the mounting arm 11 and communicates with the switching groove 111, and the boss 113 can increase the setting length of the mounting hole 112, so that the mounting hole 112 can install the nut 4 with a longer threaded groove, thereby improving the stability and reliability of the threaded part 32 and the nut 4 connection, and reducing the risk of loosening or falling off of the adjusting rod 3.

[0039] Further, as a specific embodiment in some embodiments of the present application, Figures 1 to 5 As shown, the operation part 31 is sleeved with a knob 5, and the knob 5 is integrally formed with the adjusting rod 3.

[0040] Specifically, the knob 5 is sleeved on the operation part 31, and the knob 5 is integrally formed with the adjusting rod 3, so that the user can adjust the tightness of the threaded part 32 of the adjusting rod 3 and the nut 4 by rotating the knob 5, so as to adjust the clamping force between the two mounting arms 11, thereby clamping or loosening the connecting seat 2. And the knob 5 can be an extension of the operation part 31, providing the user with a larger force arm and a more comfortable gripping surface, thereby improving the convenience and comfort of operation.

[0041] Further, as a specific embodiment in some embodiments of the present application, Figure 4 As shown, the base 1 is provided with a plurality of reinforcing ribs 14, and the plurality of reinforcing ribs 14 are annularly arranged on the periphery of the connecting piece 13.

[0042] Specifically, the base 1 is provided with a plurality of reinforcing ribs 14, and the plurality of reinforcing ribs 14 are annularly arranged on the periphery of the connecting piece 13. The reinforcing ribs 14 can effectively increase the structural strength of the base 1, uniformly distribute stress to the entire base 1, avoid stress concentration on the periphery of the connecting piece 13, ensure that the base 1 can stably support the connecting piece 13 and the mounting arm 11, and prevent the base 1 from deforming or being damaged, thereby prolonging the service life of the base 1.
