[0030] In actual use of an existing steel structure support structure that is easy to disassemble, support rod 1 and support rod 2 are fixed to the slider by anti-slip bolts 4, which means that every time support rod 1 and support rod 2 need to be disassembled, the bolts need to be turned to remove them from the slider, which consumes a certain amount of time. In the case of frequent installation and disassembly of the device, this time consumption may become very obvious, resulting in low overall disassembly efficiency. Therefore, a structure that is easier to disassemble is provided.

[0031] Embodiment 1:

[0032] like Figures 1 to 5 The utility model provides a steel structure support structure which is easy to disassemble.

[0033] Specifically, by Figure 1-Figure 5 A steel structure support structure that is easy to disassemble is provided, comprising a base 1 and a support frame 3, a fixing assembly 2 is arranged between the base 1 and the support frame 3, the fixing assembly 2 comprises a fixing plate 201 fixedly installed at the bottom of the support frame 3, two fixing rods 202 are arranged inside the base 1, the fixing plate 201 is plugged into the outer wall of the fixing rod 202, two arc-shaped clamping blocks 203 are fixedly installed on the top of the fixing plate 201, the fixing rod 202 is located between the two arc-shaped clamping blocks 203, the outer wall of the fixing rod 202 is against the inner wall of the arc-shaped clamping block 203, and the two arc-shaped clamping blocks 203 are between Two arc-shaped clamping blocks 204 are provided, and the fixing rod 202 is located between the arc-shaped clamping block 203 and the arc-shaped clamping block 204. Two tension springs 205 are connected between the two arc-shaped clamping blocks 204. A steel ball 206 is provided above the arc-shaped clamping block 204, and the steel ball 206 is located between the two arc-shaped clamping blocks 204. A U-shaped fixing frame 207 is fixedly connected to the top of the arc-shaped clamping block 203, and a reset spring 208 is connected between the U-shaped fixing frame 207 and the steel ball 206. A pull rod 209 is inserted into the U-shaped fixing frame 207, and the bottom of the pull rod 209 is fixedly connected to the outer wall of the steel ball 206.

[0034] When the pull rod 209 is pulled to drive the steel ball 206 to move upward, the steel ball 206 will squeeze the reset spring 208, and then the fixing plate 201 is sleeved on the outer wall of the fixing rod 202 to connect the support frame 3 with the base 1. After the pull rod 209 is released, the reset spring 208 will bounce the steel ball 206 back to its original position, so that the steel ball 206 is pushed back between the two arc-shaped clamping blocks 204. The elastic force of the reset spring 208 is greater than that of the tension spring 205. Therefore, when the two arc-shaped clamping blocks 204 are squeezed by the steel ball 206, they will move closer to the position of one of the arc-shaped clamping blocks 203 respectively.

[0035] When the arc-shaped clamping block 204 and the arc-shaped clamping block 203 are brought close to each other, they will squeeze the fixing rod 202, so that the fixing plate 201 and the fixing rod 202 are tightly connected together. At this time, the fixing plate 201 cannot be easily pulled out from the fixing rod 202, and the support frame 3 cannot be easily moved from the base 1. Pulling the pull rod 209 again to make the steel ball 206 away from the two arc-shaped clamping blocks 204 can separate the support frame 3 from the base 1.

[0036] Further:

[0037] like Figure 5 It is shown that the inner walls of the arc-shaped clamping block 203 and the arc-shaped clamping block 204 are integrally formed with rubber anti-skid particles, and a grab plate 11 is provided above the steel ball 206 . The grab plate 11 is located between the two fixing rods 202 , and the grab plate 11 is fixedly installed on the top of the pull rod 209 .

[0038] The rubber anti-skid particles enhance the friction between the arc-shaped clamping block 203 and the arc-shaped clamping block 204 and the fixing rod 202, so that the fixing rod 202 can be fixed more tightly. The gripping plate 11 makes the pull rod 209 easier to manipulate, so that the user can hook the gripping plate 11 with his fingers to pull the pull rod 209.

[0039] Further:

[0040] like Figure 5 It is shown that the outer wall of the arc-shaped clamping block 203 is fixedly connected with two sliding rods 4 , the arc-shaped clamping block 204 is slidably connected with the outer wall of the sliding rod 4 , and the arc-shaped clamping block 204 is slidably connected with the top of the fixed plate 201 .

[0041] The slide bar 4 prevents the two arc-shaped blocks 204 from tilting and shifting when they approach the arc-shaped clamping block 203 , so that the arc-shaped blocks 204 can maintain horizontal movement. The arc-shaped blocks 204 are slidably connected to the fixed plate 201 , so the arc-shaped blocks 204 can move when they are resisted by the steel balls 206 .

[0042] Further:

[0043] like Figure 3It is shown that a support plate 8 is fixedly installed on the inner wall of the base 1 , and the support plate 8 is provided with two through slots 12 . The fixing rod 202 is located inside the through slots 12 and is slidably connected to the through slots 12 .

[0044] The support plate 8 limits the fixing rod 202 and the gear 5 to prevent the fixing rod 202 and the gear 5 from being pulled out of the base 1 together when the support frame 3 is moved. At the same time, the through groove 12 provides sliding space for the fixing rod 202, so that when the support frame 3 is moved, the fixing rod 202 can move along the through groove 12 with the support frame 3 and the fixing plate 201.

[0045] Embodiment 2:

[0046] like Figure 2-Figure 4 It is shown that a gear 5 is fixedly installed on the outer wall of the fixed rod 202, and the two gears 5 are meshingly connected. Two racks 6 meshingly connected to the gears 5 are fixedly installed on the inner wall of the base 1. A limit ring 7 is fixedly installed on the outer wall of the fixed rod 202, and the limit ring 7 is located between the support plate 8 and the gear 5.

[0047] When the support frame 3 and the fixing plate 201 are pushed to move, the gear 5 will move along the support plate 8. When the support frame 3 moves to one side, one of the gears 5 will rotate clockwise along the support plate 8, while the other gear 5 will move counterclockwise along the support plate 8. Therefore, the meshing connection of the two gears 5 will not affect the movement of the two gears 5. The limiting ring 7 blocks the gear 5 to prevent the gear 5 from affecting the structure above the gear 5 when rotating.

[0048] When the gear 5 moves, the fixing rod 202 will also rotate. When the support frame 3 is moved to a specific position, the pull rod 209 is released to allow the steel ball 206 to return to between the two arc-shaped blocks 204. At this time, the fixing rod 202 is fixed, so that the fixing rod 202 cannot rotate, and then the position of the support frame 3 can also be fixed, so that the support frame 3 cannot be moved again.

[0049] Further:

[0050] like Figure 2-Figure 4 It is shown that two slide grooves 9 are provided on the inner bottom wall of the base 1 , and the bottom end of the fixing rod 202 is rotatably connected to two balls 10 , which are located inside the slide grooves 9 and are slidably connected to the slide grooves 9 .

[0051] When the fixed rod 202 moves following the fixed plate 201 and the support frame 3, the ball 10 will slide along the inside of the slide groove 9. The connection between the ball 10 and the slide groove 9 allows the support frame 3 to move more smoothly, and also eliminates the need for contact between the fixed rod 202 and the base 1, so as to avoid friction and wear when the outer wall of the fixed rod 202 moves along the inner bottom wall of the base 1.

[0052] Working principle:

[0053] When the pull rod 209 is pulled to drive the steel ball 206 to move upward, the steel ball 206 will squeeze the reset spring 208, and then the fixing plate 201 is sleeved on the outer wall of the fixing rod 202 to connect the support frame 3 with the base 1. After the pull rod 209 is released, the reset spring 208 will bounce the steel ball 206 back to its original position, so that the steel ball 206 is pushed back between the two arc-shaped clamping blocks 204. The elastic force of the reset spring 208 is greater than that of the tension spring 205. Therefore, when the two arc-shaped clamping blocks 204 are squeezed by the steel ball 206, they will move closer to the position of one of the arc-shaped clamping blocks 203 respectively.

[0054] When the arc-shaped clamping block 204 and the arc-shaped clamping block 203 are brought close to each other, they will squeeze the fixing rod 202, so that the fixing plate 201 and the fixing rod 202 are tightly connected together. At this time, the fixing plate 201 cannot be easily pulled out from the fixing rod 202, and the support frame 3 cannot be easily moved from the base 1. Pulling the pull rod 209 again to make the steel ball 206 away from the two arc-shaped clamping blocks 204 can separate the support frame 3 from the base 1.

[0055] When the support frame 3 and the fixing plate 201 are pushed to move, the gear 5 will move along the support plate 8. When the support frame 3 moves to one side, one of the gears 5 will rotate clockwise along the support plate 8, while the other gear 5 will move counterclockwise along the support plate 8. Therefore, the meshing connection of the two gears 5 will not affect the movement of the two gears 5. The limiting ring 7 blocks the gear 5 to prevent the gear 5 from affecting the structure above the gear 5 when rotating.

[0056] When the gear 5 moves, the fixing rod 202 will also rotate. When the support frame 3 is moved to a specific position, the pull rod 209 is released to allow the steel ball 206 to return to between the two arc-shaped blocks 204. At this time, the fixing rod 202 is fixed, so that the fixing rod 202 cannot rotate, and then the position of the support frame 3 can also be fixed, so that the support frame 3 cannot be moved again.

[0057] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical contents suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
