Description

Technical Field

[0001] The present invention relates to the technical field of steel structure factories, and specifically relates to a steel structure factory that is convenient for extension. Background Technique

[0002] A steel structure factory mainly refers to a factory whose main load-bearing members are made of steel, including steel columns, steel beams, steel structure foundations, steel roof trusses (for cases where the factory span is relatively large, steel structure roof trusses are basically used now), and steel roofs, etc. In addition, its walls can also be enclosed with brick walls.

[0003] Some existing expandable factory structures are either complex to operate and require the assistance of large professional equipment and a large number of manpower to achieve space adjustment. This not only increases the manpower and equipment costs of the enterprise, but may also delay production or warehousing arrangements due to cumbersome operations when space adjustment is urgently needed; or the structural stability after expansion or contraction is poor, and safety hazards such as loosening and deformation of the connection parts are likely to occur, affecting the safety of personnel and equipment in the factory and reducing the service life of the factory. In addition, in terms of the fixing method after space adjustment, some factories cannot achieve rapid and reliable fixing, and the extended part is likely to be displaced due to external factors such as vibration and wind force during subsequent use, unable to meet the requirements of long-term stable use. Summary of the Invention

[0004] The purpose of the present invention is to provide a steel structure factory that is convenient for extension to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A steel structure factory that is convenient for extension, including a factory shell, a factory door is hinged to the front of the factory shell through a hinge, receiving grooves are respectively opened on both sides of the factory shell, engaging holes one are respectively opened at equal intervals on the front and back of the factory shell, and an extension component is arranged inside the factory shell.

[0006] Preferably, the extension component includes: extension parts, symmetrically arranged on both sides of the factory shell; blocking parts, symmetrically arranged on the front and back of the factory shell; fixing parts, symmetrically arranged inside the factory shell.

[0007] Preferably, the extension parts include: slide rails, symmetrically and fixedly installed at the top and bottom of the factory shell; slide seats, slidably connected inside the slide rails.

[0008] Preferably, an extended inner plate is fixedly installed between the sliding seats. The extended inner plate is movably connected to the factory building shell through a storage groove. Clamping holes II are equidistantly formed in the front and back of the extended inner plate respectively. A fixed side plate is fixedly installed on the outer side of the extended inner plate. Fixing plates are symmetrically and fixedly installed on the other side of the fixed side plate. A movable rod is slidably sleeved inside the fixing plate. A first pulling plate is fixedly installed at one end of the movable rod. The other end of the movable rod is rotatably connected to a baffle through a bearing. A spring is sleeved on the outer wall of the movable rod. One end of the spring is fixedly connected to the first pulling plate, and the other end of the spring is fixedly connected to the fixing plate.

[0009] By arranging a structural combination of the first pulling plate, the movable rod, the baffle and the spring, when it is necessary to extend the lateral space of the factory building, the operator only needs to pull the first pulling plate. While the spring is stretched, the movable rod can drive the baffle to move, thereby reducing the friction between the sliding seat and the slide rail, enabling the fixed side plate to be pulled more easily, and finally driving the extended inner plate to slide out of the storage groove along the slide rail, realizing the extension of the factory building space.

[0010] Preferably, the blocking component includes: mounting plates symmetrically and equidistantly fixedly installed on the front and back of the factory building shell; guide rods symmetrically fixedly installed on the top of the mounting plates.

[0011] Preferably, a connection groove is formed on one side of the mounting plate, and a movable opening is formed on the top of the mounting plate. A limit top plate is fixedly installed at the top of the guide rod. A connecting plate is slidably sleeved on the outer wall of the guide rod. A first spring is sleeved on the outer wall of the guide rod. One end of the first spring is fixedly connected to the connecting plate, and the other end of the first spring is fixedly connected to the limit top plate. A connecting rod is slidably sleeved inside the limit top plate. A second pulling plate is fixedly installed at the top of the connecting rod. A connecting plate is fixedly installed at the bottom of the connecting rod. A vertical baffle is fixedly installed at the bottom of the connecting plate. The vertical baffle is movably connected to the mounting plate through the movable opening. The connection groove is adapted to the baffle.

[0012] The setting of the first spring enables the whole structure to have the function of automatic reset. When the second pulling plate is released, under the elastic restoring force of the first spring, the connecting plate will be automatically pulled to move along the guide rod, so that the vertical baffle quickly and accurately returns to the initial position.

[0013] Preferably, the fixing component includes: fixing columns symmetrically fixedly installed on the front inner wall and the back inner wall of the factory building shell.

[0014] Preferably, one side of the fixing column is symmetrically provided with an installation slot, and the fixing column is fixedly installed with a guide short rod through the installation slot, and the outer wall sliding sleeve of the guide short rod is provided with a clamping block, and the clamping block is adapted to the clamping hole one and the clamping hole two, and the clamping block is slidably connected with the fixing column through the installation slot, and the outer wall sleeve of the guide short rod is provided with a spring two, one end of the spring two is fixedly connected to the clamping block, and the other end of the spring two is fixedly connected to the fixing column, and the other side of the clamping block is respectively fixedly installed with a connecting top plate and a connecting bottom plate, and the connecting bottom plate is arranged directly below the connecting top plate, and the other sides of the connecting top plate and the connecting bottom plate movably penetrate one side of the inner wall of the fixing column and extend to one side of the outer wall of the fixing column, and are fixedly installed with a connecting vertical plate, and the other side of the connecting vertical plate is fixedly installed with a handle two.

[0015] The design of the fitting block, the first fitting hole and the second fitting hole matching each other ensures the accurate positioning of the extended inner plate and the outer shell of the plant building during the connection.

[0016] The present invention provides a steel structure factory building that is easy to extend and has the following beneficial effects:

[0017] (1) The present invention rotates the movable rod 90 degrees to align the movable rod with the connecting groove, and pulls the pull plate 1 outward. The pull plate 1 drives the baffle plate to separate from the mounting plate through the movable rod. At the same time, when the pull plate 1 is pulled, the spring is stretched to separate the fixed side plate from the factory shell. The operator can pull the fixed side plate by the handle, and the fixed side plate drives the extended inner plate to move. The extended inner plate slides outward on the slide rail of the factory shell through the slide seats on both sides and gradually moves out of the storage groove, thereby achieving the effect of extending the horizontal space of the factory.

[0018] (2) According to the present invention, after the extended inner plate is moved to a suitable position, it needs to be fixed to ensure the stability of the factory building structure. The fixing components start to work, and the guide short rod on the fixing column provides a sliding guide for the locking block. Under the elastic force of the second spring, the locking block partially protrudes from the outside of the fixing column. When the extended inner plate is unfolded to the corresponding position, the locking block is aligned with the second locking hole on the extended inner plate and the first locking hole on the factory building shell. Under the action of the second spring, the locking block automatically snaps into the corresponding locking hole, thereby achieving the effect of fixing the extended inner plate to the factory building shell after extension.

[0019] (3) After the extended inner plate is completely stored, the present invention pushes the pull plate 1, which drives the baffle plate through the connecting groove and penetrates the mounting plate through the movable rod, and rotates the baffle plate. At this time, the baffle plate is subjected to resistance and the spring does not rebound. Then, the pull plate 2 is released, the spring 1 contracts, and the connecting plate is pulled downward, so that the vertical baffle plate drops back to the initial position in the mounting plate, preventing the baffle plate from detaching from the mounting plate, thereby achieving the effect of fixing the extended inner plate after storage.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Embodiment 1:

[0034] A preferred embodiment of the steel structure factory building that is convenient for extension provided by the present invention is as Figures 1-6 shown: A steel structure factory building that is convenient for extension includes a factory building outer shell 1. A factory door 2 is hinged to the front of the factory building outer shell 1 through a hinge. Receiving grooves are respectively opened on both sides of the factory building outer shell 1. Clamping holes one 4 are respectively and equidistantly opened on the front and back of the factory building outer shell 1. An extension assembly 3 is arranged inside the factory building outer shell 1. The extension assembly 3 includes: extension components 31, symmetrically arranged on both sides of the factory building outer shell 1; blocking components 32, symmetrically arranged on the front and back of the factory building outer shell 1; fixing components 33, symmetrically arranged inside the factory building outer shell 1. The extension components 31 include: slide rails 311, symmetrically and fixedly installed on the top and bottom of the factory building outer shell 1; sliding seats 312, slidably connected inside the slide rails 311; an extension inner plate 313 is fixedly installed between the sliding seats 312. The extension inner plate 313 is movably connected to the factory building outer shell 1 through the receiving groove. Clamping holes two 3111 are respectively and equidistantly opened on the front and back of the extension inner plate 313. A fixed side plate 314 is fixedly installed on the outer side of the extension inner plate 313. Fixing plates 316 are symmetrically and fixedly installed on the other side of the fixed side plate 314. A movable rod 317 is slidably sleeved inside the fixing plate 316. A pull plate one 318 is fixedly installed at one end of the movable rod 317. The other end of the movable rod 317 is rotatably connected to a baffle 3112 through a bearing. A spring 319 is sleeved on the outer wall of the movable rod 317. One end of the spring 319 is fixedly connected to the pull plate one 318, and the other end of the spring 319 is fixedly connected to the fixing plate 316.

[0035] Furthermore, in the embodiment, the movable rod 317 is rotated ninety degrees so that the movable rod 317 is aligned with the connecting groove 329, and the pull plate 318 is pulled outward. The pull plate 318 drives the baffle 3112 to separate from the mounting plate 321 through the movable rod 317. At the same time, when the pull plate 318 is pulled, the spring 319 is stretched to separate the fixed side plate 314 from the factory shell 1. The operator can pull the fixed side plate 314 through the handle 315, and the fixed side plate 314 drives the extended inner plate 313 to move. The extended inner plate 313 slides outward on the slide rail 311 of the factory shell 1 through the slide seats 312 on both sides, and gradually moves out of the storage slot, thereby extending the horizontal space of the factory.

[0036] Embodiment 2:

[0037] See also Figures 1-6 , and on the basis of the first embodiment, it is further obtained that the blocking component 32 includes: a mounting plate 321, which is symmetrically and equidistantly fixedly installed on the front and back of the plant shell 1; a guide rod 322, which is symmetrically and fixedly installed on the top of the mounting plate 321; a connecting groove 329 is opened on one side of the mounting plate 321, and a movable opening is opened on the top of the mounting plate 321. A limited top plate 323 is fixedly installed on the top of the guide rod 322, and a connecting plate 327 is provided on the outer wall sliding sleeve of the guide rod 322. A spring 327 is provided on the outer wall sleeve of the guide rod 322. 24. One end of spring 1 324 is fixedly connected to connecting plate 327, and the other end of spring 1 324 is fixedly connected to limiting top plate 323. The internal sliding sleeve of limiting top plate 323 is provided with connecting rod 325, and pull plate 2 326 is fixedly installed on the top of connecting rod 325, and connecting plate 327 is fixedly installed on the bottom end of connecting rod 325. Vertical baffle 328 is fixedly installed on the bottom of connecting plate 327, and vertical baffle 328 is movably connected to mounting plate 321 through a movable opening, and connecting groove 329 is adapted to baffle 3112.

[0038] Furthermore, in the embodiment, by pulling the pull plate 2 326 upward, the pull plate 2 326 drives the connecting plate 327 to move upward through the connecting rod 325, and at the same time, the connecting plate 327 drives the vertical baffle 328 to separate from the mounting plate 321, and the connecting plate 327 compresses the spring 1 324 when moving. When the extended inner plate 313 is completely stored, the pull plate 1 318 is pushed, and the pull plate 1 318 drives the baffle 3112 to pass through the connecting groove 329 through the mounting plate 321 through the movable rod 317, and the baffle 3112 is rotated. At this time, the baffle 3112 is subjected to resistance, and the spring 319 does not rebound. Subsequently, the pull plate 2 326 is released, the spring 1 324 contracts, and the connecting plate 327 is pulled downward, so that the vertical baffle 328 drops back to the initial position in the mounting plate 321, preventing the baffle 3112 from separating from the mounting plate 321.

[0039] Embodiment three:

[0040] Please refer to Figures 1-6 , and on the basis of Embodiments 1 and 2, it is further obtained that the fixing component 33 includes: fixing columns 331, symmetrically and fixedly installed on the front inner wall and the back inner wall of the factory building shell 1; installation grooves are symmetrically opened on one side of the fixing columns 331, and the fixing columns 331 are fixedly installed with guiding short rods 332 through the installation grooves. A clamping block 333 is slidably sleeved on the outer wall of the guiding short rod 332. The clamping block 333 is adapted to the first clamping hole 4 and the second clamping hole 3111. The clamping block 333 is slidably connected to the fixing column 331 through the installation groove. A second spring 334 is sleeved on the outer wall of the guiding short rod 332. One end of the second spring 334 is fixedly connected to the clamping block 333, and the other end of the second spring 334 is fixedly connected to the fixing column 331. A connecting top plate 335 and a connecting bottom plate 336 are respectively fixedly installed on the other side of the clamping block 333. The connecting bottom plate 336 is arranged directly below the connecting top plate 335. The other sides of the connecting top plate 335 and the connecting bottom plate 336 movably penetrate through one side of the inner wall of the fixing column 331 and extend to one side of the outer wall of the fixing column 331, and a connecting vertical plate 337 is fixedly installed. A second handle 338 is fixedly installed on the other side of the connecting vertical plate 337.

[0041] Further, after the extended inner plate 313 moves to a suitable position in the embodiment and needs to be fixed to ensure the stability of the factory building structure, the fixing component starts to work. The guiding short rod 332 on the fixing column 331 provides sliding guidance for the clamping block 333. Under the elastic force of the second spring 334, part of the clamping block 333 protrudes outside the fixing column 331. When the extended inner plate 313 is unfolded to the corresponding position, the clamping block 333 is aligned with the second clamping hole 3111 on the extended inner plate 313 and the first clamping hole 4 on the factory building shell 1. Under the action of the second spring 334, the clamping block 333 automatically snaps into the corresponding clamping hole, realizing the fixed connection between the extended inner plate 313 and the factory building shell 1. If it is necessary to adjust the position of the extended inner plate 313, pull the second handle 338. The second handle 338 drives the connecting vertical plate 337 to move. The connecting vertical plate 337 drives the connecting top plate 335 and the connecting bottom plate 336 to move. The connecting top plate 335 and the connecting bottom plate 336 drive the clamping block 333 to slide on the guiding short rod 332, overcoming the elastic force of the second spring 334, so that the clamping block 333 withdraws from the clamping hole.

[0042] During use, when it is necessary to extend the factory building, pull up the second pull plate 326. The second pull plate 326 drives the connecting plate 327 to move upward through the connecting rod 325. At the same time, the connecting plate 327 drives the vertical baffle 328 to disengage from the mounting plate 321, and the connecting plate 327 compresses the first spring 324 when moving. After the vertical baffle 328 disengages from the mounting plate 321, rotate the movable rod 317 by 90 degrees so that the movable rod 317 is aligned with the connecting groove 329. Pull out the first pull plate 318 outward. The first pull plate 318 drives the baffle 3112 to disengage from the mounting plate 321 through the movable rod 317. At the same time, when pulling the first pull plate 318, the spring 319 is stretched, so that the fixed side plate 314 is separated from the factory building shell 1. The operator can pull the fixed side plate 314 through the handle 315. The fixed side plate 314 drives the extended inner plate 313 to move. The extended inner plate 313 slides outward on the slide rail 311 of the factory building shell 1 through the two slide seats 312 on both sides and gradually moves out of the storage groove, realizing the extension of the horizontal space of the factory building. When the extended inner plate 313 moves to the appropriate position, it needs to be fixed to ensure the stability of the factory building structure. The fixing component starts to work. The guiding short rod 332 on the fixing column 331 provides sliding guidance for the engaging block 333. Under the elastic force of the second spring 334, part of the engaging block 333 protrudes outside the fixing column 331. When the extended inner plate 313 is unfolded to the corresponding position, the engaging block 333 is aligned with the second engaging hole 3111 on the extended inner plate 313 and the first engaging hole 4 on the factory building shell 1. Under the action of the second spring 334, the engaging block 333 automatically snaps into the corresponding engaging hole, realizing the fixed connection between the extended inner plate 313 and the factory building shell 1. If it is necessary to adjust the position of the extended inner plate 313, pull the second handle 338. The second handle 338 drives the connecting vertical plate 337 to move. The connecting vertical plate 337 drives the connecting top plate 335 and the connecting bottom plate 336 to move. The connecting top plate 335 and the connecting bottom plate 336 drive the engaging block 333 to slide on the guiding short rod 332, overcoming the elastic force of the second spring 334, so that the engaging block 333 withdraws from the engaging hole. At this time, the extended inner plate 313 can be moved and the extended inner plate 313 can be stored. When the extended inner plate 313 is completely stored, push the first pull plate 318. The first pull plate 318 drives the baffle 3112 to pass through the mounting plate 321 through the connecting groove 329 through the movable rod 317. Rotate the baffle 3112. At this time, the baffle 3112 is subject to resistance and the spring 319 will not rebound. Then release the second pull plate 326. The first spring 324 contracts, pulling the connecting plate 327 to move downward, so that the vertical baffle 328 drops back to the initial position inside the mounting plate 321 to prevent the baffle 3112 from disengaging from the mounting plate 321.
