Description

Technical Field

[0001] The invention relates to the field of construction safety equipment production, in particular to a safety protection device used in dock construction projects. Background Art

[0002] A dock is a transportation hub located along the sea, river, lake, or reservoir, with water-land transport equipment and conditions for safe entry, exit, and berthing of ships. Dock construction is usually carried out near waters, and there are a large number of high-altitude operations during dock construction, such as the construction of dock trestles and the installation of loading and unloading equipment. During these high-altitude operations, workers are prone to falling accidents. In order to avoid safety accidents, it is necessary to design a safety protection device based on dock construction projects, which can physically prevent people from accidentally stepping off the edge and falling, and at the same time, can block objects falling from above to ensure the safety of people below.

[0003] After searching, the authorization announcement number CN218148151 U is a safety protection device for port terminal construction, including two support columns, and straight grooves are opened on the opposite sides of the inner wall between the two support columns. A combination mechanism is slidably matched between the two straight grooves. The combination mechanism can combine the railings through the combination mechanism, so that personnel can transport the combination mechanism and the support columns separately during transportation. Such a setting can greatly increase the number of railings in transportation, thereby improving the transportation speed of the railings by users. Since the device is inserted between the two support columns through the slider on the first first rod body, and then multiple second rod bodies are inserted into the groove of the first first rod body one by one, and finally another first rod body is plugged into the second rod body On the top of the body, since the slider and the straight groove and the upper and lower ends of multiple second rod bodies need to be precisely aligned and installed in the two first rod bodies, this step is relatively complicated to install, and each set of parts of the device needs to be installed on-site, which will take up a large space during transportation, resulting in low on-site installation efficiency. Secondly, the positioning mechanism is threadedly connected on the two box bodies through two screws, so that the positioning rod can slide into the straight groove along the slide groove and hinder the slider of the upper first rod body to prevent the first rod body from sliding freely. However, when the two screws cannot be driven synchronously, the positioning rod will be positioned differently in the process of sliding into the straight groove along the slide groove, causing the upper first rod body to shake on the second rod body, resulting in poor fixing effect and low installation efficiency.

[0004] Therefore, it is necessary to propose a safety protection device based on dock construction engineering to solve the above technical problems. Summary of the invention

[0040] (3) The present invention sets up a locking system, and through the cooperation of locking torsion, the first conical wheel, the second conical wheel, the multilateral limit rod and the extrusion rod, the slider can be accurately controlled to achieve accurate locking of the final position of the support column, thereby ensuring that the support column is in the accurate preset position after the protective device is installed, thereby improving the installation accuracy.

DETAILED DESCRIPTION

[0052] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0053] like Figure 1-Figure 3As shown, a safety protection device for dock construction projects includes a base 1, the top of the base 1 is provided with symmetrically distributed corner seats 11, and support columns 12 are provided between the opposite sides of the corner seats 11. A plurality of protection rods 13 are provided on the top of the base 1, and enclosure plates 14 are installed at the front and rear ends of the base 1. The safety protection device is based on the base 1, and the corner seats 11 and support columns 12 are provided on the top of the base 1, providing a basic support framework for the entire protection device. At the same time, a plurality of protection rods 13 are also provided on the top of the base 1 for blocking protection, and enclosure plates 14 are installed at the front and rear ends to further enhance the protection effect. The first module assembly 2 is provided on the plurality of protection rods 13, and is used to combine the plurality of protection rods 13 to form a modular assembly, so as to realize the modular assembly of the plurality of protection rods 13. The first module assembly 2 includes: a first rotating plate 21, the number of which is at least one group, and a group is two, a group of first rotating plates 21 is connected to rotate in a cross shape through a rotating shaft, and a group of first rotating plates 21 is provided at the upper and lower ends of the protection rod 13. The fixing block 210 is symmetrical, and its front and rear ends are rotatably connected to the left end of the first rotating plate 21 of the left group through a rotating shaft; the connecting plate 22, the number of which is at least one, and the front and rear ends of the top are provided with a slide groove, and the connecting plate 22 is symmetrically arranged at the upper and lower ends of the protective rod 13; the moving block 23 is slidably connected to the inner side of the slide groove through a slide rail, and the right end of the first rotating plate 21 of the left group and the left and right ends of the other group of first rotating plates 21 are rotatably connected to the moving block 23 through a rotating shaft, and the first rotating plates 21 and the moving block 23 at the upper and lower ends and a group of The intersections of the first rotating plate 21 are rotatably connected to the protective rod 13 through a rotating shaft; there are two module plates 24, which are symmetrically installed between the fixed block 210 on the left and the connecting plate 22 on the right, and the module plate 24 is in a U-shaped structure; module slots 25 are provided at the lower sides of the two module plates 24 on the opposite sides, and the module slots 25 are arranged in a T-shape, and the module slots 25 in the module plates 24 are connected by sliding inside the support column 12; the support column 12 is located below the module plate 24 and has a first notch 26 on both sides, the first A compression spring limiting rod 27 is slidably connected inside the slot 26, and the lower part of the compression spring limiting rod 27 slides through the lower part of the support column 12 and extends out. By setting the compression spring limiting rod 27, the compression spring limiting rod 27 can be retracted into the first slot 26, which is convenient for folding so as to reduce the occupied space. The middle part of the compression spring limiting rod 27 at the front and rear ends is fixedly connected with a pressed plate 28, and the left and right ends of the base 1 are provided with limiting grooves 29 adapted to the compression spring limiting rod 27, and the lower part of the compression spring limiting rod 27 is tightly attached to the inner side of the limiting groove 29.

[0054] It should be noted that, first, in the preparation stage or during transportation, the device can be in a folded state, and multiple protection rods 13 are installed at specific positions, namely, between the fixed block 210, the intersection of the first rotating plates 21 arranged in a cross pattern, and the connecting plate 22. This installation method utilizes the shaft connection between the components, so that the protection rod 13 can flexibly cooperate with these components. Then, by retracting the module plates 24 on both sides, the retraction of the module plates 24 will cause the multiple first rotating plates 21 to rotate. Because the first rotating plates 21 and the module plates 24 are indirectly connected through the fixed block 210 and other components, the rotation of the first rotating plate 21 will drive the connected moving block 23 to slide on the slide groove of the connecting plate 22. In this process, due to the synergistic effect of the rotating shaft and the sliding connection between the components, the protection rod 13 will gradually fold up with the movement of these components. This folding design is convenient for transportation and storage.

[0055] When installing the device on site, unfold the module plates 24 on both sides so that the moving block 23 slides in the slide groove of the connecting plate 22. As the moving block 23 slides, the spacing between the multiple protection rods 13 gradually increases, and then the module plates 24 are unfolded vertically from the corner seats 11 on the two support columns 12 on the base 1, and the module grooves 25 on the module plates 24 slide downward along the inside of the support columns 12. When the module plates 24 slide to a certain position on the support columns 12, the bottom end of the module plates 24 will contact the pressed plate 28. Due to the downward pressure of the module plates 24 during the sliding process, the pressed plate 28 will be acted upon by the force and drive the compression spring limiting rod 27 to move downward. The compression spring limiting rod 27 slides in the first notch 26, and its bottom end extends out of the bottom of the support column 12 and is inserted into the limiting groove 29 on the base 1. Through the cooperation between the compression spring limiting rod 27 and the limiting groove 29, the module plates 24 are limited on the support column 12, thereby fixing the various components of the entire protection device in a suitable position, completing rapid assembly, and improving installation efficiency.

[0056] The present invention sets a first module assembly 2, and this technical solution can be folded during transportation or storage, thereby reducing the occupied space. In an environment with limited space such as a dock construction site, this foldable design is convenient for storing and managing protective devices, and avoids affecting construction operations and on-site management due to the protective devices occupying too much space. At the same time, the downward extrusion force of the module plate 24 drives the compression spring limit rod 27 to be inserted into the limit groove 29, thereby realizing the rapid limitation of the module plate 24 on the support column 12, greatly reducing the time and labor cost of on-site installation, and improving installation efficiency.

[0057] like Figure 3-Figure 4As shown, the second module assembly 211 is arranged inside the base 1, and is used to enable the support columns 12 on both sides to be quickly unfolded from the corner seat 11 during the installation of the guardrail. The second module assembly 211 includes: second slots 212, of which there are at least four in number and are arranged in a rectangular array above the base 1, and the second slots 212 are long structures; a compression spring telescopic rod 213, which is fixedly mounted on the side wall of the second slot 212; a first rack plate 214, which is fixedly mounted on the moving end of the compression spring telescopic rod 213, and the lower part of the first rack plate 214 and the bottom wall of the second slot 212 are connected by a slide rail; a reset gear 215, which is symmetrically mounted on the front and rear ends of the support column 12, and the lower part of the reset gear 215 is meshed with the first rack plate 214.

[0058] It should be noted that during transportation, the support columns 12 on both sides are folded horizontally with the base 1. At this time, the compression spring telescopic rod 213 is in a compressed state. When the support column 12 needs to be turned away from the inside of the corner seat 11 to a vertical state, the external force constraint on the compression spring telescopic rod 213 is released, and the spring potential energy stored therein begins to be released. Under the action of the spring force, the first rack plate 214 moves along the compression spring telescopic rod 213 close to its fixed end. The movement of the first rack plate 214 will drive the reset gear 215 to rotate in the opposite direction. The rotation of the reset gear 215 will drive the support column 12 connected thereto to start rotating from the base 1, and finally the support column 12 is arranged vertically on the corner seat 11, completing the conversion from the transportation state to the working state. The whole process is fast and efficient. The present invention can realize the rapid deployment of the support column 12 by setting the second module. The deployment action of the support column 12 can be completed in a short time by utilizing the cooperation of the compression spring telescopic rod 213, the first rack plate 214 and the reset gear 215, which greatly reduces the time for on-site installation of the protective device and improves the efficiency of the entire installation process. Especially for large-scale dock construction projects, the construction period can be effectively shortened, and the support column 12 can be folded with the base 1 during transportation, which reduces the space occupied by the entire protective device and is convenient for transportation and storage.

[0059] like Figure 3-Figure 5 As shown, a third slot 221 in a rectangular array is provided on the top of the base 1, and a slider 222 is connected to the third slot 221 through a slide rail. An auxiliary rotating plate 223 is rotatably connected between the opposite sides of the sliders 222 at the front and rear ends and the middle of the side wall of the support column 12, and a damper is arranged on the slider 222 in the third slot 221.

[0060] It should be noted that when the spring potential energy of the compression spring telescopic rod 213 is released, the first rack plate 214 drives the reset gear 215 to rotate rapidly, thereby causing the support column 12 to start rotating on the angle seat 11. In this process, the rotation of the support column 12 will cause the slider 222 to slide in the third notch 221. The slider 222 is provided with a damper, which will generate resistance to the sliding of the slider 222. This resistance reacts to the rotation process of the support column 12 through the auxiliary rotating plate 223, thereby buffering the rapid rotation of the support column 12 and reducing its impact force, making the position of the support column 12 after installation more accurate and stable, avoiding installation deviation caused by impact force, and preventing the support column 12 from accidentally shaking, displacing or component damage due to impact force during the deployment process, thereby ensuring the safety of personnel at the construction site and the smooth progress of construction.

[0061] like Figure 3-Figure 4 As shown, the sliders 222 located on the left and right sides of the rear end are equipped with matching blocks 224 of different lengths at one end away from the protective rod 13, and the middle part of the protective plate 14 is provided with a transverse groove slidably connected to the matching block 224. The two matching blocks 224 of different lengths are equipped with a second rack plate 225 at one end away from the slider 222, and the middle part of the rear end of the base 1 is rotatably connected with a synchronous gear 226 meshing with the second rack plate 225.

[0062] It should be noted that when one of the support columns 12 starts to rotate from the angle seat 11, since it is connected to the auxiliary rotating plate 223 and the slider 222, the rotation of the support column 12 will drive the auxiliary rotating plate 223 and the slider 222 to move. Therefore, the auxiliary rotating plate 223 will push the slider 222 to slide in the third slot 221, and the sliding of the slider 222 will drive the matching block 224 connected to it to move together. At the same time, the movement of the matching block 224 will cause the second rack plate 225 connected to it to move accordingly. When one second rack plate 225 moves, it will drive the synchronous gear 226 to rotate. Since the synchronous gear 226 is also meshed with the other second rack plate 225, the rotation of the synchronous gear 226 will drive the other second rack plate 225 to move. The movement of the other second rack plate 225 will drive the matching block 224 and the slider 222 connected to it to move. Therefore, the movement of the slider 222 will drive the auxiliary rotating plate 223 to move, thereby causing the other support column 12 to start rotating from the angle seat 11. In this way, the synchronous rotation of the two support columns 12 is achieved. Through this synchronous rotation mechanism, the two support columns 12 can be deployed at the same time without separate operations. Compared with the method of installing and deploying the support columns 12 one by one, it greatly saves installation time and speeds up the installation progress of the entire protective device. The synchronous rotation makes the deployment angles of the two support columns 12 consistent, ensuring the symmetry and stability of the overall structure of the protective device.

[0063] like Figure 5-Figure 6As shown, a lock box 231 is provided on the top of the left and right ends of the base 1, and a lock torsion 232 is rotatably connected to the top of the lock box 231. A linkage groove is opened in the inner cavity of the lock box 231, and a first conical wheel 233 fixedly connected to the lock torsion 232 is rotatably connected to the bottom wall of the linkage groove. The front and rear ends of the linkage groove are rotatably connected to the second conical wheel 234 meshing with the first conical wheel 233, and a polygonal limiting rod 235 rotatably connected to the lock box 231 is installed on the back side of the second conical wheel 234 at the front and rear ends. The front and rear ends of the lock box 231 are threadedly connected to an extrusion rod 236 slidably connected to the polygonal limiting rod 235, and a sleeve is installed on the opposite side of the slider 222 at the front and rear ends, and the extrusion rod 236 is squeezed in the sleeve when extended.

[0064] When the support column 12 is unfolded, the slider 222 will move synchronously in the third slot 221 with the unfolding action of the support column 12. When the slider 222 moves to a specific position, the operator rotates the lock twist 232, and the rotation of the lock twist 232 will directly drive the first conical wheel 233 to rotate around the bottom wall of the linkage groove. When the first conical wheel 233 rotates, it will drive the two second conical wheels 234 to rotate synchronously around their respective linkage grooves. When the second conical wheel 234 rotates, it will drive the polygonal limiting rods 235 connected thereto to rotate around their respective rotation axes in the lock box 231. When the polygonal limiting rod 235 rotates, due to the extrusion rod 236 and the polygonal limiting rod 236, the extrusion rod 236 and the polygonal limiting rod 236 are pressed together. 235 is a sliding connection and is threadedly connected to the lock box 231, so the extrusion rod 236 moves along the axial straight line in the lock box 231, that is, the extrusion rod 236 is extended on the lock box 231 and squeezed inside the sleeve, limiting the further movement of the slider 222 in the third notch 221, thereby indirectly controlling the movement of the support column 12 connected to the slider 222 through the auxiliary rotating plate 223 and other components, completing the control state locking of the support column 12, so that it remains in the current deployed position, ensuring the stability of the overall structure of the protective device;

[0065] By accurately controlling the slider 222 through the locking system, the final position of the support column 12 can be accurately locked, which helps to ensure that the support column 12 is in the accurate preset position after the protective device is installed, thereby improving the installation accuracy of the entire protective device.

[0066] like Figure 5 and Figure 7As shown, vertically arranged telescopic grooves 2311 are provided at the left and right ends of the top of the base 1, and limit plates 2312 are installed on the tops of the left and right ends of the telescopic grooves 2311. A triangular structure is arranged in the middle of the lower part of the lock box 231, and reset grooves 2313 are provided at the left and right ends of the moving block 23. A reset spring rod 2314 slidably connected to the limit plate 2312 is installed on the bottom wall of the limit plate 2312, and a symmetrically arranged first pushing seat 2315 is connected to the middle of the bottom wall of the telescopic groove 2311 through a slide rail, and an inclined groove tightly attached to the triangular inclined surface is provided on the opposite sides of the first pushing seats 2315 at the front and rear ends, and a connecting rod 2316 is installed on the back side of the first pushing seats 2315 at the front and rear ends, and a second pushing seat 2317 is installed on the end of the connecting rod 2316 away from the first pushing seat 2315, and the end of the second pushing seat 2317 away from the connecting rod 2316 slides through the third notch 221, and an inclined surface contact is arranged between the second pushing seat 2317 and the slider 222.

[0067] It should be noted that: when the slider 222 slides inside the third notch 221, since the slider 222 and the second push seat 2317 are arranged to be in contact with each other at an inclined surface, the inclined surface of the slider 222 will produce an extrusion effect with the inclined surface of the second push seat 2317 during the sliding process, so that the second push seat 2317 is extended inwardly inside the telescopic groove 2311. When the second push seats 2317 at the front and rear sides are extended, the connecting rod 2316 is driven to move, and then the first push seat 2315 is also moved. When the first push seats 2315 at the front and rear sides move, their inclined grooves will squeeze the triangular inclined surfaces of the lock case 231, so that the lock case 231 extends upward from the telescopic groove 2311 under the action of this squeezing force to reach a usable working position. In the process of the lock case 231 extending from the telescopic groove 2311, the limit plate 2312 will squeeze the return spring rod 2314 as the lock case 231 rises, so that the return spring rod 2314 enters a compressed state. The return spring rod 2314 now stores elastic potential energy, preparing for the subsequent retraction operation of the lock case 231;

[0068] When the lock box 231 is not used later, the elastic potential energy stored in the reset spring rod 2314 is released, and the reset spring rod 2314 will return to its original state under the action of its own elastic force. In this process, the reset spring rod 2314 will exert an upward force on the limit plate 2312, and this force will be transmitted to the lock box 231 through the limit plate 2312, prompting the lock box 231 to extend downward into the telescopic slot 2311, thereby realizing the retraction of the lock box 231, making it convenient for the entire device to be folded and transported, and reducing the occupied space.

[0069] like Figure 2 , Figure 4 and Figure 8As shown, the quick control component 3 is arranged on the base 1, and is used to automatically enter the control state when the first module component 2 is inserted into the second module component 211. The quick control component 3 includes: a control board 31, at least two of which are fixedly connected to the rear end of the corner seat 11; a control spring rod 32, the rear end of which slides through the top of the control board 31; a control push-pull plate 33, the control push-pull plate 33 and the rear end of the control spring rod 32 are fixedly connected, and a handle is installed in the middle of the control push-pull plate 33; a control block 34, which is fixedly connected to the front end of the control spring rod 32, and a bevel is arranged above the control block 34; an extrusion block 35, which is fixedly connected to the bottom of the module slot 25, and a bevel groove adapted to the bevel is opened below the extrusion block 35; a longitudinal groove 111, which runs through the middle of the support column 12 and is slidably connected to the extrusion block 35.

[0070] It should be noted that when the module plate 24 on the first module assembly 2 slides downward along the inside of the support column 12, the extrusion block 35 connected below the module plate 24 also moves downward accordingly, and the extrusion block 35 gradually approaches the control block 34 and interacts with it. During the downward movement of the extrusion block 35, its bevel groove slides along the bevel of the control block 34, and the downward movement of the control block 34 drives the control spring rod 32 into a compressed state. As the extrusion block 35 continues to move downward, the control block 34 moves to the top of the extrusion block 35 under the extrusion action of the bevel and squeezes it, thereby quickly completing the limit of the module plate 24 on the support column 12 and ensuring that the module plate 24 is in a suitable installation position;

[0071] When the control block 34 needs to be disassembled, the operator pulls the handle installed in the middle of the control push-pull plate 33 to move the control push-pull plate 33 away from the base 1. The movement of the control push-pull plate 33 will drive the control spring rod 32 to move backward as a whole. The control block 34 at the front end of the control spring rod 32 will also move backward synchronously, so that the control block 34 will lose its limiting effect on the extrusion block 35. By releasing the compression spring limit rod 27, the module plate 24 can be quickly extended upward on the support column 12, which can achieve fast disassembly efficiency;

[0072] Through the clever beveled cooperation between the extrusion block 35 and the control block 34 and the compression of the control spring rod 32, the module plate 24 can be automatically and quickly limited in the process of the module plate 24 sliding down. This limiting method does not require complicated manual adjustment operations, greatly improves the efficiency of the protective device during the installation process, enables the module plate 24 to be quickly and accurately fixed at a suitable position on the support column 12, and reduces installation time and labor costs.

[0073] like Figure 1 and Fig. 9As shown, a folding plate 311 is installed at the front end of the control push-pull plate 33 , and a bottom plate 312 tightly attached to the bottom of the folding plate 311 is installed at the intersection of a group of first rotating plates 21 located in the middle of the lower part.

[0074] When the squeezing block 35 is squeezing on the control block 34, the control block 34 is squeezed and moves downward, and the control push-pull plate 33 is driven to move backward as a whole. During the backward movement of the folding plate 311, the bottom plate 312 can slide downward through one side of the folding plate 311. When the control block 34 completely enters the top of the squeezing block 35 and completes the squeezing action, the spring potential energy of the control spring rod 32 is released, driving the control push-pull plate 33 and the folding plate 311 to reset forward together. While the folding plate 311 is resetting, it will squeeze tightly against the top of the bottom plate 312. The bottom plate 312 is located in the first rotating plate 21 in the middle below the first module assembly 2, and can exert a downward squeezing effect on a group of first rotating plates 21 in the middle below the first module assembly 2, thereby reducing the possible shaking, displacement, etc. of the first rotating plate 21, so that the first module assembly 2 can be more firmly installed in the protective device, thereby ensuring the stability of the overall structure of the protective device.

[0075] like Figure 4 and Fig. 9 As shown, folding grooves 313 are provided on the tops of the support columns 12 at the left and right ends, and the folding plates 311 are arranged at an angle below. When the support columns 12 are folded on the corner seats 11, the folding plates 311 on the push-pull plates 33 are controlled to squeeze on the folding grooves 313 to facilitate folding during transportation.

[0076] It should be noted that when the protective device needs to be transported or stored, so that the support column 12 is folded on the corner seat 11, the support column 12 is in a horizontal state on the base 1, and the folding plate 311 on the control push-pull plate 33 can be squeezed between the folding grooves 313 on the support column 12, so that the support column 12 can be horizontally attached to the base 1 during the folding process, which is convenient for the transportation or storage of the entire protective device. The inclined structure of the folding plate 311 allows it to better fit the inner wall of the folding groove 313 during the folding process. During transportation, folding the support column 12 can greatly reduce the space occupied by the protective device and improve transportation efficiency.

[0077] The working principle of the present invention is that the safety protection device for dock construction projects is used, when in use, preparation or transportation, the protection bar 13 is installed in a specific position, and the module plate 24 is retracted to drive the first rotating plate 21 to rotate, and the moving block 23 slides in the sliding groove of the connecting plate 22, so that the protection bar 13 is folded for easy transportation;

[0078] During on-site installation, unfold the module plate 24, slide the moving block 23 to increase the spacing between the protection bars 13, and slide the module slot 25 of the module plate 24 along the support column 12. When the module plate 24 contacts the pressed plate 28, the compression spring limit rod 27 is inserted into the limit slot 29 to fix the components of the protection device.

[0079] During transportation, the support column 12 and the base 1 are horizontally folded, and the compression spring telescopic rod 213 is compressed. When unfolded, the compression spring telescopic rod 213 releases potential energy, and the first rack plate 214 moves to drive the reset gear 215 to rotate in the opposite direction, driving the support column 12 to rotate from the angle seat 11 to a vertical state;

[0080] The rotation of one support column 12 drives the slider 222, the matching block 224, and the second rack plate 225 to move, and the other second rack plate 225 is driven to move by the synchronous gear 226, so that the two support columns 12 can rotate synchronously;

[0081] During the unfolding process of the support column 12, when the slider 222 moves to a specific position, the lock buckle 232 is rotated to drive the first conical wheel 233, the second conical wheel 234, and the multilateral limiting rod 235 to rotate, so that the extrusion rod 236 extends out of the sleeve of the extrusion slider 222, restricting the movement of the slider 222 and locking the position of the support column 12;

[0082] When the module plate 24 slides down, the extrusion block 35 approaches the control block 34, and the control block 34 compresses the control spring rod 32 through the beveled edge cooperation, and the control block 34 moves to the top of the extrusion block 35 to complete the limit of the module plate 24;

[0083] Pull the handle of the control push-pull plate 33 to move the control spring rod 32 and the control block 34 backward, release the restriction on the extrusion block 35, and realize the rapid disassembly of the module plate 24;

[0084] When the extrusion block 35 squeezes the control block 34, the push-pull plate 33 is controlled to move backward, and the folding plate 311 also moves synchronously. When it is reset above the extrudable bottom plate 312, it stabilizes a group of first rotating plates 21 under the first module assembly 2. When the support column 12 is folded, the folding plate 311 can be squeezed in the folding groove 313 for easy transportation and storage.
