[0042] Specifically, the end surface of the first connecting rod 1 is provided with a connecting part which is inserted into the first support frame 4, and the plug-in part can be bonded or welded, or can be threadedly connected or screw-fixedly connected, and the utility model does not limit this, in order to improve the overall detachability, in the embodiment, the first connecting rod 1 and the first support frame 4 are threadedly connected, that is, the connecting part is a threaded column, and a matching threaded hole is arranged at the corresponding position of the first support frame 4.

[0043] The plug-in block 11 is formed on the end surface of the first connecting rod 1 and is in an integral structure. The plug-in hole 21 is formed on the end surface of the second connecting rod, and the depth of the plug-in hole 21 is greater than the length of the plug-in block 11, so as to ensure that the plug-in block 11 can be completely inserted into the plug-in hole 21. The locking notch 22 is formed through the side wall of the second connecting rod 2, and the locking notch 22 is close to the opening of the plug-in hole 21. The locking assembly 3 is sleeved on the outside of the second connecting rod 2, the locking assembly 3 can close the locking notch 22, and part of the locking assembly 3 can be deep into the locking notch 22, such as using an elastic structure to set a stretchable part, the stretchable part can abut against the plug-in block 11 or be clamped on the plug-in block 11, and a cam structure can also be rotationally arranged, and the protruding part of the cam is abutted against the plug-in block 11 by rotating.

[0044] When the first support frame 4 and the second support frame 5 are fixed, only the first connecting rod 1 and the second connecting rod 2 are connected with the first support frame 4 and the second support frame 5 respectively, and then the locking assembly 3 is arranged, the plug-in block 11 is inserted into the plug-in hole 21, and the locking assembly 3 is partially inserted into the locking notch 22 and abuts against the plug-in block 11, so that the plug-in block 11 is locked in the plug-in hole 21, and then the first connecting rod 1 is locked with the second connecting rod 2, that is, the quick locking between the first support frame 4 and the second support frame 5 is realized. Therefore, when the locking mechanism is used, only the first connecting rod 1 and the second connecting rod 2 are connected, and then the plug-in block 11 is inserted into the plug-in slot and locked by the locking assembly 3, so that the quick installation of the first support frame 4 and the second support frame 5 is completed, the positioning and alignment accuracy required is low, the installation time between the first support frame 4 and the second support frame 5 is small, and the efficiency is high, so that the installation efficiency of the whole support device is effectively improved.

[0045] With reference to Figure 3 And Figure 4 The locking assembly 3 comprises a locking sleeve 31 and a locking part 32. The locking sleeve 31 is sleeved on the second connecting rod 2, and the locking sleeve 31 has a locking hole communicating with the locking notch 22; the locking part 32 is rotationally connected to the locking sleeve 31, and the locking part 32 has a locking protrusion which can be inserted into the locking notch 22 through the locking hole and abut against the first connecting rod 1.

[0046] Specifically, the locking sleeve 31 is located outside the end of the second connecting rod 2 close to the first connecting rod 1, and the locking sleeve 31 can be threadedly connected with the first connecting rod 1 or connected by a screw. In this embodiment, two through holes are arranged on the opposite sides of the locking sleeve 31, and a threaded hole is arranged at the corresponding position of the first connecting rod 1. A screw is arranged in each through hole and is threadedly connected in the threaded hole, so as to fix the locking sleeve 31 on the second connecting rod 2.

[0047] A through hole is arranged at the position of the locking sleeve 31 corresponding to the locking notch 22 as a locking hole, two lugs are arranged outside the locking hole, and the locking part 32 is rotationally connected between the two lugs through a rotating rod. The locking part 32 can be in the shape of a cam to form a locking protrusion, or in other shapes such as a square block, and a part of the side close to the locking hole is protruded to form a locking protrusion. In order to facilitate the rotation of the locking part 32, a long handle structure can be arranged on the side wall of the locking part 32, or a connecting hole can be arranged on the locking part 32, and a rod-shaped structure inserted into the connecting hole can also drive the locking part 32 to rotate.

[0048] By setting the locking sleeve 31 and the locking portion 32, after the insertion block 11 is inserted into the insertion hole 21, the locking portion 32 can be rotated so that the locking protrusion of the locking portion 32 extends into the locking gap 22 through the locking hole, and when the locking protrusion abuts against the insertion block 11, the insertion block 11 can be locked in the insertion hole 21, and at the same time, the locking portion 32 can also be locked due to the abutting force, so that the locking of the insertion block 11 can be quickly completed.

[0049] Optionally, the locking assembly 3 further comprises a handle 33. The handle 33 is fixedly arranged on the locking portion 32 and extends along the circumference of the locking sleeve 31.

[0050] Specifically, the handle 33 in a long rod shape is fixedly connected to the outside of the locking portion 32, and the two can be in an integrated structure. The end of the handle 33 away from the locking portion 32 is bent and extends along the outside wall of the locking sleeve 31, which can quickly drive the locking portion 32 to rotate through the handle 33, and on the other hand, when the locking portion 32 is locked, the handle 33 is attached to the outside wall of the locking sleeve 31, thereby reducing the situation that the handle 33 is moved by being accidentally touched.

[0051] Optionally, the locking mechanism further comprises a pressing portion 6. The pressing portion 6 is arranged on the side of the insertion block 11 facing the locking gap 22, and the pressing portion 6 can be inserted into the locking gap 22 and abut against the locking portion 32.

[0052] Specifically, a mounting cavity is formed in the side of the insertion block 11, and the pressing portion 6 is embedded in the mounting cavity, and part of the pressing portion 6 protrudes out of the mounting cavity. The thickness of the protruding part of the pressing portion 6 is just equal to the thickness of the locking gap 22, so that when the insertion block 11 is inserted into the insertion hole 21, the side wall of the insertion block 11 can be attached to the hole wall of the insertion hole 21, and the pressing portion 6 can be just inserted into the locking gap 22.

[0053] In order to play a guiding effect, the width of the pressing portion 6 can be equal to the width of the locking gap 22, so that the side wall of the pressing portion 6 can be slidably attached to the side wall of the locking gap 22.

[0054] The pressing portion 6 can have a certain elasticity, for example, it can be made of POM (polyoxymethylene) or super glue, or it can be made of a rigid material, so that it can deform when being abutted. The pressing portion 6 can also be made of a rigid material, at this time, a spring or other elastic structure can be arranged on the back of the pressing portion 6, so that the pressing portion 6 has a certain displacement ability when being abutted.

[0055] By setting the pressing part 6, when the plug-in block 11 is inserted into the plug-in hole 21, the pressing part 6 can be inserted into the locking gap 22, and then when the locking part 32 is rotated to make the locking protrusion extend into the locking gap 22, the locking protrusion can extrude the pressing part 6, so that the pressing part 6 generates a certain deformation or displacement, and when the rotating part is rotated to the position, the pressing part 6 can form sufficient abutting force with the locking protrusion by corresponding elasticity to form locking, and the specific abutting force can be designed by changing the elastic deformation capacity or displacement capacity of the pressing part 6 or the size of the locking protrusion, which can meet the locking requirement, and the utility model does not make limitation on this.

[0056] Optionally, the side wall of the pressing part 6 has a clamping hole 61 matched with the locking protrusion.

[0057] Specifically, the clamping hole 61 is arranged at the middle position of the side wall of the pressing part 6, the clamping hole 61 can correspond to the locking hole, and the aperture of the clamping hole 61 is smaller than the maximum outer diameter of the locking protrusion, so that the locking protrusion can be partially clamped in the clamping hole 61. By arranging the clamping hole 61, the locking protrusion is partially clamped in the clamping hole 61 when locking, so that the locking protrusion and the pressing part 6 not only form sufficient abutting force, but also have clamping effect, thereby improving the locking effect of the plug-in block 11.

[0058] Optionally, the locking mechanism further comprises a limiting part 62. One end of the limiting part 62 is fixedly connected with the plug-in block 11, the other end can elastically stretch and retract, and the limiting part 62 can be extruded by the hole wall of the plug-in hole 21 when the plug-in block 11 is inserted into the plug-in hole 21. The plug-in hole 21 has a limiting hole 24 for inserting the limiting part 62.

[0059] Specifically, the limiting part 62 can be arranged on the plug-in block 11 or the pressing part 6, and in the embodiment, the limiting part 62 is arranged on the pressing part 6 and located below the clamping hole 61. A blind hole is arranged on one side of the pressing part 6 inserted into the plug-in hole 21, a spring or other elastic structure can be arranged in the blind hole, part of the limiting part 62 is arranged in the blind hole and connected with the spring or other elastic structure, and the other part of the limiting part 62 protrudes from the blind hole and can be spherical. The limiting part 62 can also be directly arranged at the opening of the blind hole, and the limiting part 62 is made of elastic material at this time. The limiting hole 24 is arranged on the hole wall of the plug-in hole 21, and the limiting hole 24 is located below the locking hole, and the limiting part 62 and the limiting hole 24 form clamping cooperation when the plug-in block 11 is completely inserted.

[0060] By setting the limiting portion 62 and the limiting hole 24, when the plug-in block 11 is inserted into the plug-in hole 21, the limiting portion 62 is extruded with the hole wall of the plug-in hole 21 to generate a certain displacement or deformation, when the plug-in block 11 is completely inserted into the plug-in hole 21, the limiting portion 62 corresponds to the limiting hole 24, then the limiting portion 62 can be smoothly inserted into the limiting hole 24, thereby forming a clamping. When the clamping action occurs, a certain sound can be emitted to prompt the operator that the plug-in block 11 has been plugged in place.

[0061] In order to facilitate disassembly, the plug-in hole 21 penetrates the side wall of the second connecting rod 2. So that when disassembling, the rod-shaped structure can be inserted into the plug-in hole 21 at the same time, the limiting portion 62 can be pushed out of the limiting hole 24, so that the limiting action of the limiting portion 62 and the limiting hole 24 can be quickly released.

[0062] Optionally, the outer side wall of the second connecting rod 2 is provided with a mounting notch 23 for mounting the locking assembly 3.

[0063] Specifically, the mounting notch 23 is provided on the outer side wall of the upper end of the second connecting rod 2, the bottom wall of the mounting notch 23 forms a receiving table, the locking sleeve 31 is lapped on the receiving table, and the height of the locking sleeve 31 is equal to the height of the mounting notch 23, so that the top wall of the locking sleeve 31 is flush with the end face of the second connecting rod 2, and when the plug-in block 11 is inserted into the plug-in hole 21, the end face of the first connecting rod 1 is in contact with the end face of the second connecting rod 2 and the end face of the locking sleeve 31.

[0064] By setting the mounting notch 23, space can be provided for the installation of the locking assembly 3, thereby improving the installation strength between the locking assembly 3 and the second connecting rod 2, and the upper and lower sides of the locking assembly 3 can be respectively limited by the first connecting rod 1 and the second connecting rod 2 to ensure that the locking assembly 3 does not shift after locking the plug-in block 11.

[0065] The support device includes a first support frame 4 and a second support frame 5. The second support frame 5 is fixedly installed with the first support frame 4 through the locking mechanism as in the above embodiment.

[0066] When the support device is installed, the first support frame 4 and the second support frame 5 are directly installed and fixed through the corresponding locking mechanism, the locking mechanism has low requirements for positioning and alignment accuracy during installation and fixation, and can quickly realize the installation and fixation of the first support frame 4 and the second support frame 5, and has strong connection strength, thereby being beneficial to saving the time spent during the installation of the whole support device and effectively improving the installation efficiency.

[0067] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and replacements can be made without departing from the protection scope of the present application.
