[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1:

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention provides an automatic locking device for a combined connecting rod, comprising a connecting rod body 1 and a combined rod 2. Six insertion holes 3 are evenly arranged on the outer surface of the connecting rod body 1. The inside of the insertion hole 3 is also connected to an L-shaped groove 4. A first spring 5 is arranged inside the L-shaped groove 4. A locking mechanism 6 for buckling the combined rod 2 is arranged on the upper end of the first spring 5.

[0036] The above structure, under the action of the first spring 5, can drive the locking mechanism 6 to move elastically, and then the locking mechanism 6 can be clamped into the combination rod 2, so that the connecting rod body 1 can be quickly locked without the aid of tools during assembly, which greatly improves the assembly and disassembly efficiency and is particularly suitable for building products that are frequently assembled.

[0037] The connecting rod body 1 is internally rotatably connected with a connecting sleeve 7, and a sliding rod 8 is provided in the middle of the connecting sleeve 7, which rotates with the connecting sleeve 7 and maintains vertical sliding. The sliding rod 8 rotates with the rotation of the connecting sleeve 7 and can slide up and down. The upper end of the sliding rod 8 passes through the upper part of the connecting rod body 1 and is fixedly connected with a pressing head 9. The bottom end of the sliding rod 8 is fixedly connected with a toggle block 10, and the height of the toggle block 10 is higher than the locking mechanism 6.

[0038] In the above structure, pressing the pressing head 9 drives the slide bar 8 and the toggle block 10 to move downward, thereby pressing down the locking mechanism 6, thereby disengaging the locking mechanism 6, making it easier to disassemble and achieving the purpose of rapid disassembly and assembly.

[0039] Embodiment 2:

[0040] Based on the first embodiment, Figure 6 and Figure 7 Specifically, the locking mechanism 6 includes a connecting plate 61 fixedly connected to the upper end of the first spring 5, and two fixing rods 62 are fixedly connected to the upper surface of the connecting plate 61. The upper ends of the two fixing rods 62 are fixedly connected to a clamp 63, and the outer diameter of the outer clamp 63 is larger than the outer diameter of the inner clamp 63.

[0041] The above structure can improve the stability of the connection by using two clamps 63 with different outer diameters.

[0042] One end of the combination rod 2 is fixedly connected to a plug rod 201 , and two sockets 202 are provided at the bottom of the plug rod 201 . The diameter of the outer socket 202 is smaller than that of the inner socket 202 . The plug rod 201 is docked with the socket 3 , and the socket 202 is correspondingly buckled with the clamp 63 .

[0043] In summary, by providing the clamping heads 63 and the sockets 202 with different diameters, the connection of the combination rod 2 is made more stable, while the flexibility and diversity of assembly are ensured.

[0044] A second spring 15 is further disposed inside the insertion hole 3 , and a pressing plate 16 is fixedly connected to the other end of the second spring 15 , and the pressing plate 16 abuts against the plug-in rod 201 .

[0045] The above structure increases the contact pressure between the plug rod 201 and the connecting rod body 1 and improves the stability of the connection by arranging the second spring 15 and the extrusion plate 16 inside the plug hole 3.

[0046] Embodiment three:

[0047] Based on the second embodiment, Figure 4 Specifically, a bearing seat 17 is fixedly connected to the interior of the connecting rod body 1 , and the connecting sleeve 7 is fixedly connected to the interior of the bearing seat 17 .

[0048] The above structure can provide position-limiting support for the connecting sleeve 7 through the connecting function of the bearing seat 17 .

[0049] The outer walls on both sides of the slide rod 8 are fixedly connected with the first slide block 18, the inner wall of the connecting sleeve 7 is provided with a first slide groove 19, the first slide block 18 is slidably connected in the first slide groove 19, the inner bottom of the first slide groove 19 is fixedly connected with the third spring 20, and the upper end of the third spring 20 is fixedly connected to the bottom of the first slide block 18.

[0050] With the above structure, under the limiting action of the first slider 18 and the first slide groove 19 , the slide rod 8 can rotate along with the rotation of the connecting sleeve 7 , and under the action of the third spring 20 , the slide rod 8 can return to its original position after moving up and down.

[0051] Embodiment 4:

[0052] Based on the third embodiment, Figure 5 Specifically, a turntable 11 is rotatably connected to the upper position of the connecting rod body 1, and second sliders 21 are fixedly connected to the outer walls of both sides of the slide rod 8. A second slide groove 22 is opened in the middle of the turntable 11, and the second slider 21 is slidably connected to the second slide groove 22.

[0053] The above structure realizes the rotation of the slide bar 8 as the turntable 11 rotates.

[0054] A damping chamber 12 is provided at the connection between the connecting rod body 1 and the rotating disk 11 . A plurality of first elastic balls 13 are fixedly connected to the upper inner wall of the damping chamber 12 . A plurality of second elastic balls 14 are fixedly connected to the upper surface of the rotating disk 11 . The first elastic balls 13 abut against the second elastic balls 14 .

[0055] The above structure can increase the damping feeling of the turntable 11 and avoid shaking under the mutual interference of the first elastic ball 13 and the second elastic ball 14. That is, by providing the damping chamber 12 and the elastic ball at the connection between the connecting rod body 1 and the turntable 11, the turntable 11 can rotate smoothly, the friction force can be increased, the deviation during operation can be reduced, and the use experience can be improved.

[0056] Secondly, the combined connecting rod automatic locking device also includes a pointer 23 fixedly connected to the bottom of the outer surface of the turntable 11, and the pointer 23 points to the socket 3. That is, the design of the pointer 23 facilitates the user to quickly identify the position of the socket 3, facilitates disassembly, and improves the convenience of operation.

[0057] Working principle: Take Example 4 as an example:

[0058] When the combination rod 2 needs to be plugged into the connecting rod body 1, it is only necessary to insert the plugging rod 201 of the combination rod 2 into the insertion hole 3 of the connecting rod body 1. Specifically, under the action of the first spring 5, the locking mechanism 6 can be driven to move elastically, and then the clamping head 63 of the locking mechanism 6 can be clamped into the socket 202, so that the connecting rod body 1 can be quickly locked without the help of tools during assembly, which greatly improves the assembly and disassembly efficiency and is particularly suitable for building products that are frequently assembled. Secondly, by arranging the second spring 15 and the extrusion plate 16 inside the insertion hole 3, the contact pressure between the plugging rod 201 and the connecting rod body 1 is increased, and the stability of the connection is improved;

[0059] When the required combination rod 2 needs to be removed, the turntable 11 is rotated to make the pointer 23 point to the corresponding socket 3, and then the pressing head 9 is pressed downward to drive the slide bar 8 and the toggle block 10 to move downward, thereby pressing the locking mechanism 6 downward, thereby disengaging the locking mechanism 6, making it convenient to disassemble and achieve the purpose of quick disassembly and assembly.
