Description

Technical Field

[0001] This utility model relates to the field of placement rack technology, specifically a steel door panel movable placement rack. Background Technology

[0002] Steel door panels are the door leaf parts made of steel. They have high hardness, strength, and durability, and are widely used in industrial, commercial, and residential buildings. As a common building material, steel has high tensile and compressive strength, and can withstand large external impacts and deformations, ensuring the stability and safety of the door leaf. Steel door panels provide high security performance, resisting damage and impacts from intruders, increasing the building's protective capabilities, and slowing the spread of fire in the event of a fire, protecting the safety of people and property inside. Through processing and surface coating, steel door panels can be presented in a variety of styles and colors, making buildings more aesthetically pleasing.

[0003] The existing steel door panel moving and placing rack uses casters at the bottom to move the steel door panels above. However, after the steel door panels are moved to the placement position, the casters at the bottom of the rack affect the stability of the rack when placing the panels. Furthermore, when the existing steel door panel moving and placing rack is not full, there will be gaps between the steel door panels and the rack, causing the steel door panels to sway and tip over during transportation. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to again Figure 1-4 This utility model provides a steel door panel movable placement rack, including a base 100, mounting plates 110 fixedly connected to both sides of the base 100, and movable wheels 111 rotatably connected to the bottom sides of the mounting plates 110. Mounting grooves 120 are formed on both sides of the interior of the base 100. Gear rotating screws 121 are rotatably connected to the bottom sides of the inner cavity of the mounting grooves 120. The bottom ends of the gear rotating screws 121 penetrate the mounting grooves 120 and extend to the bottom of the base 100. A first threaded sleeve 122 is screwed onto the outer wall of the gear rotating screw 121. A support plate 130 is fixedly connected to the bottom end of the first threaded sleeve 122. An installation chamber 140 is fixedly connected to one side of the base 100. The inner cavity of the installation chamber 140 is rotatably connected to the bottom sides of the support plate 130. A first gear transmission rod 141 is connected, one end of which passes through the mounting chamber 140 and the base 100 and extends into the inner cavity of the mounting groove 120. A first drive gear 142 is fixedly connected to both sides of the outer side of the first gear transmission rod 141. The first drive gear 142 meshes with the gear rotating screw 121. A rotating rod 150 is rotatably connected to one side of the mounting chamber 140. One end of the rotating rod 150 passes through the mounting chamber 140 and extends into the inner cavity of the mounting chamber 140. A second drive gear 151 is fixedly connected to both sides of the outer side of the rotating rod 150. The second drive gear 151 meshes with the first gear transmission rod 141. A first protective plate 160 is fixedly connected to the top of the base 100.

[0022] Specifically, when the position of the placement rack does not need to be moved, rotating the rotating rod 150 causes the second drive gear 151 on the rotating rod 150 to drive the first gear transmission rod 141 meshing with it to rotate, causing the first drive gear 142 on the first gear transmission rod 141 to drive the gear rotating screw 121 meshing with it to rotate, causing the first threaded sleeve 122 installed on the gear rotating screw 121 to descend, causing the support plate 130 at the bottom of the first threaded sleeve 122 to descend and contact the ground to support the placement rack. When the placement rack needs to be moved, reversing the rotating rod 150 will raise the support plate 130 and make the moving wheel 111 contact the ground.

[0023] Example 2: Please refer to again Figure 1-4The base 100 has a guide frame 200 embedded inside. A movable seat 210 is slidably connected to the inner side of the guide frame 200. A second protective plate 220 is fixedly connected to the top of the movable seat 210. A transmission chamber 230 is fixedly connected to one side of the movable seat 210. Gear driven screws 240 are rotatably connected to both sides of the inner cavity of the movable seat 210. One end of the gear driven screw 240 passes through the movable seat 210 and extends to the outer side of the movable seat 210. A second threaded sleeve 241 is screwed onto the outer wall of the gear driven screw 240. A compression limiting plate 250 is fixedly connected to one end of the second threaded sleeve 241. One side of the compression limiting plate 250 contacts the guide frame 200. Two limiting rods 251 are fixedly connected to the other side of the limiting plate 250. One end of the limiting rod 251 is fixedly connected to the movable seat 210. A second gear transmission rod 260 is rotatably connected to one side of the inner cavity of the transmission chamber 230. One end of the second gear transmission rod 260 passes through the transmission chamber 230 and extends into the inner cavity of the movable seat 210. The other end of the second gear transmission rod 260 is meshed with the gear driven screw 240. A gear drive rod 270 is rotatably connected to the top of the transmission chamber 230. The bottom end of the gear drive rod 270 passes through the transmission chamber 230 and extends into the inner cavity of the transmission chamber 230. The bottom end of the gear drive rod 270 is meshed with the second gear transmission rod 260.

[0024] Specifically, rotating the gear drive rod 270 drives the second gear transmission rod 260, which is meshed with it, to rotate. The second gear transmission rod 260 then drives the driven screws 240 on both sides, which are meshed with it, to rotate. This causes the second threaded sleeve 241 mounted on the driven screw 240 to move, and the compression limiting plate 250 connected to the second threaded sleeve 241 to move synchronously under the limitation of the telescopic rod. This cancels the compression contact with the guide frame 200 and releases the limitation fixation on the moving compartment. The position of the moving compartment can then be adjusted, causing the second protective plate 220 on the moving compartment to move and cooperate with the first protective plate 160 to compress and limit the steel door panel. Then, reversing the gear drive rod 270 resets the compression limiting plate 250 to compress and contact the guide frame 200, thus limiting and fixing the moving compartment.

[0025] Working principle: When the position of the placement rack does not need to be moved, rotating the rotating rod 150 causes the second drive gear 151 on the rotating rod 150 to drive the first gear transmission rod 141 meshing with it to rotate, causing the first drive gear 142 on the first gear transmission rod 141 to drive the gear rotating screw 121 meshing with it to rotate, causing the first threaded sleeve 122 installed on the gear rotating screw 121 to descend, causing the support plate 130 at the bottom of the first threaded sleeve 122 to descend and contact the ground to support the placement rack. When the placement rack needs to be moved, reversing the rotating rod 150 will cause the support plate 130 to rise, causing the moving wheel 111 to contact the ground.

[0026] Rotating the gear drive rod 270 causes the gear drive rod 270 to drive the second gear transmission rod 260, which in turn drives the driven screws 240 on both sides, which are also meshed with the gear drive rods 260, to rotate. This causes the second threaded sleeve 241 mounted on the driven screw 240 to move, and the compression limiting plate 250 connected to the second threaded sleeve 241 to move synchronously under the limitation of the telescopic rod. This cancels the compression contact with the guide frame 200 and releases the limitation fixation on the moving compartment. The position of the moving compartment can then be adjusted, causing the second protective plate 220 on the moving compartment to move and cooperate with the first protective plate 160 to compress and limit the steel door panel. Then, reversing the gear drive rod 270 resets the compression limiting plate 250 to compress and contact the guide frame 200, thus limiting and fixing the moving compartment.
