Description

Technical Field

[0001] This utility model relates to the field of template snap-fit ​​technology, and in particular to a template stable snap-fit ​​structure. Background Technology

[0002] Formwork is a temporary structure used for shaping and supporting concrete during construction. When installing formwork, it is often spliced ​​using a snap-fit ​​structure. By optimizing the mechanical design, material selection, and combination of the snap-fit ​​joints, it is ensured that the formwork can remain fixed in position and firmly connected when subjected to lateral pressure and vibration loads during concrete pouring, thus avoiding quality problems such as formwork bulging and grout leakage due to connection failure.

[0003] Most common snap-fit ​​mechanisms currently use bolts for direct fixing. This connection method has a simple structure and is prone to loosening during use. When assembling two templates, manual pushing is required to align the plates before bolting. However, when using bolts to fix the plate connection, someone must always push the plates to ensure a tight closure. Once the pressure is released, the plates will not be tightly joined. Therefore, this application proposes a template stable snap-fit ​​structure. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a template stable snap-fit ​​structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a template stable snap-fit ​​structure, comprising two plates, which are connected in a left-right distributed manner. A detachable locking mechanism is provided at the center of the front side of the connection end of the two plates, and snap-fit ​​mechanisms are provided at the top and bottom of the front side of the connection end of the two plates. A docking groove is provided at the left end of each of the two plates, and a docking plate is installed at the right end of each of the two plates. The docking plate on the right side of the plate can be inserted into the docking groove on the left side of the other plate.

[0006] Optionally, the locking mechanism includes a first fixing block, a second fixing block, a rack plate, a transmission gear, and a limiting component. The first fixing block and the second fixing block are respectively installed at the middle position on the front side of the connecting end of the two plates. A through-hole is opened on the side of both the first fixing block and the second fixing block. The rack plate is inserted into the through-hole on the side of the first fixing block and the second fixing block. A baffle that fits against the right side of the second fixing block is fixedly installed on the right end of the rack plate. A gear groove is provided at the bottom of the rack plate. A limiting tooth groove is opened at the top of the rack plate. A circular inner groove is opened at the bottom of the through-hole on the side of the first fixing block. The transmission gear is rotatably installed in the inner groove. The top of the transmission gear extends into the through-hole and meshes with the gear groove at the bottom of the rack plate. A square storage groove is opened at the top of the through-hole on the side of the first fixing block. The limiting component is movably installed in the storage groove and can engage with the limiting tooth groove at the top of the rack plate.

[0007] Optionally, a first handle extending into the inner groove and fixedly connected to the transmission gear shaft is rotatably inserted into the front of the first fixing block, and a second handle extending into the storage groove is threaded into the top of the first fixing block, with one end of the second handle located in the storage groove rotatably connected to the top of the limiting component.

[0008] Optionally, the limiting component includes a lifting block, a limiting block, and a first spring. The lifting block is located in the storage slot, and a first groove is provided at the bottom of the lifting block. A fixed shaft is installed at the upper position in the first groove. The top of the limiting block is rotatably sleeved on the fixed shaft. The first spring is fixedly connected between the left side of the inner wall of the first groove and the left side of the limiting block, and the right side of the limiting block is in contact with the right side of the first groove. The right side of the bottom end of the limiting block is set as an arc surface, and the shape of the limiting tooth groove at the top of the rack plate is adapted to the shape of the bottom end of the limiting block.

[0009] Optionally, the top of the lifting block is provided with a shaft groove, and a bearing is fixedly installed in the shaft groove. The bottom end of the second handle is fixedly connected to the inner ring wall of the bearing.

[0010] Optionally, the top of the second fixing block is provided with a first through hole, and the right end of the rack plate is provided with a second through hole that runs vertically through and is aligned with the first through hole. A first bolt is inserted through the first through hole and the second through hole.

[0011] Optionally, each of the four corners on the sides of the first and second fixing blocks is fixedly equipped with a hanging ear, and each hanging ear is connected to the plate body by a threaded bolt.

[0012] Optionally, the snap-fit ​​mechanism includes a plug-in plate and a connecting plate. The plug-in plate is fixedly installed on the front side of the right side plate, and the connecting plate is fixedly installed on the front side of the left side plate. The connecting plate is C-shaped, and the left end of the plug-in plate can be inserted between the connecting plates.

[0013] Optionally, a second groove is provided at the top and bottom of the left end of the plug-in plate. A locking block is movably inserted into each of the two second grooves. Both sides of the locking block extending out of the second groove are set as bevels. A second spring is fixedly connected between the inner end of each of the two second grooves and the corresponding locking block. The top and bottom of the inner wall of the connecting plate are provided with slots that are adapted to the shape of the beveled end of the locking block. When the left end of the plug-in plate is inserted between the connecting plates, the parts of the two locking blocks extending out of the second grooves are respectively engaged in the two slots.

[0014] Optionally, each card block has a first threaded hole that runs through the front and back on its side. The front side of the left end of the plug-in plate has two second threaded holes that communicate with the second groove. When the card block is engaged in the slot, the first threaded hole on the card block is aligned with the corresponding second threaded hole, and a second bolt is threaded between the first threaded hole and the second threaded hole.

[0015] The beneficial effects of this utility model are:

[0016] By using threaded bolts, the first and second fixing blocks in the locking mechanism are respectively installed at the middle position of the front mating ends of the two plates. Then, the rack plate is inserted into the through hole on the second fixing block, and the second fixing block is fixed and locked with the first bolt. Then, the other end of the rack plate is inserted into the through hole on the first fixing block, so that the bottom of the rack plate is connected with the top of the transmission gear. By turning the first handle, the transmission gear meshes with the gear groove at the bottom of the rack plate, thereby driving the rack plate to move to the left between the first fixing blocks. The movement of the rack plate can drive the second fixing block to move closer to the first fixing block, thereby completing the mating of the two plates.

[0017] When the rack plate moves within the first fixed block, the rack plate can be locked in place by the limiting component. The limiting block in the limiting component is squeezed by the limiting groove at the top of the rack plate, and will rotate around the fixed axis and squeeze the first spring. Since the right side of the limiting block is in contact with the inner wall of the first groove, it cannot rotate to the right, thus preventing the rack plate from moving to the right. This locks the rack plate in place, so that after the plates are joined, the two plates can always be tightly joined together due to the obstruction of the limiting component.

[0018] During the process of the two plates approaching and docking, the plug plate on the right plate will be inserted between the connecting plates on the left plate. The inclined surfaces of the locking blocks at the top and bottom of the plug plate are squeezed and move into the second groove. When the plug plate and the connecting plate are fully docked, the locking blocks will be locked into the slot by the elastic force released by the second spring. Finally, the second bolt is used to fix the position of the locking blocks. In this way, the top and bottom of the docking end of the plates can be reinforced by the locking mechanism.

Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] Please see Figures 1-7This utility model provides a technical solution: a template stable snap-fit ​​structure, including two plates 1, which are connected in a left-right distributed manner. A detachable locking mechanism 2 is provided at the center of the front side of the connection end of the two plates 1, and snap-fit ​​mechanisms 3 are provided at the top and bottom of the front side of the connection end of the two plates 1. A docking groove 101 is opened at the left end of each of the two plates 1, and a docking plate 102 is installed at the right end of each of the two plates 1. The docking plate 102 on the right side of plate 1 can be inserted into the docking groove 101 on the left side of the other plate 1. The locking mechanism 2 can enhance the connection stability at the middle position of the connection end of the two plates 1, and the two snap-fit ​​mechanisms 3 can strengthen the connection stability at the top and bottom of the connection end of the plates 1, thereby improving the overall stability of the two plates 1 after docking.

[0030] like Figures 2-5 As shown, the locking mechanism 2 includes a first fixing block 21, a second fixing block 22, a rack plate 24, a transmission gear 25, and a limiting assembly 28. The first fixing block 21 and the second fixing block 22 are respectively installed at the middle position on the front side of the connecting end of the two plates 1. A through-hole is opened on the side of both the first fixing block 21 and the second fixing block 22. The rack plate 24 is inserted into the through-hole on the side of the first fixing block 21 and the second fixing block 22. A baffle 23 that fits against the right side of the second fixing block 22 is fixedly installed on the right end of the rack plate 24. A gear groove 241 is provided at the bottom of the rack plate 24, and a limiting groove 242 is provided at the top of the rack plate 24. A circular inner groove is provided at the bottom of the through-hole on the side of the first fixing block 21. The transmission gear 25 is rotatably installed in the inner groove, and the top of the transmission gear 25 extends into the opening and meshes with the gear groove 241 at the bottom of the rack plate 24. A square storage groove 27 is provided on the top of the side opening of the first fixing block 21. The limiting component 28 is movably installed in the storage groove 27, and the limiting component 28 can engage with the limiting tooth groove 242 at the top of the rack plate 24. The rotation of the transmission gear 25 causes it to mesh with the gear groove 241 at the bottom of the rack plate 24, thereby driving the rack plate 24 to move to the left between the first fixing blocks 21. The movement of the rack plate 24 can drive the second fixing block 22 to move closer to the first fixing block 21, thereby driving the right plate 1 to dock with the left plate 1.

[0031] like Figure 2 , Figure 3 and Figure 5As shown, a first handle 26 is rotatably inserted into the front of the first fixing block 21, extending into the inner groove and fixedly connected to the shaft of the transmission gear 25. A second handle 29 is threaded into the top of the first fixing block 21, extending into the storage groove 27. One end of the second handle 29 located in the storage groove 27 is rotatably connected to the top of the limiting component 28. By turning the first handle 26, the transmission gear 25 can be driven to mesh and rotate with the gear groove 241 at the bottom of the rack plate 24. By turning the second handle 29, the limiting component 28 can be driven to move up and down in the storage groove 27.

[0032] like Figure 3 and Figure 5 As shown, the limiting component 28 includes a lifting block 280, a limiting block 283, and a first spring 284. The lifting block 280 is located inside the storage slot 27. A first groove 281 is formed at the bottom of the lifting block 280. A fixed shaft 282 is installed at the upper position inside the first groove 281. The top end of the limiting block 283 is rotatably sleeved on the fixed shaft 282. The first spring 284 is fixedly connected between the left side of the inner wall of the first groove 281 and the left side of the limiting block 283. The right side of 283 fits into the right side of the first groove 281. The right side of the bottom end of the limiting block 283 is set as an arc surface. The shape of the limiting tooth groove 242 at the top of the rack plate 24 matches the shape of the bottom end of the limiting block 283. The limiting block 283 in the limiting assembly 28 engages with the limiting tooth groove 242 at the top of the rack plate 24, which can prevent the rack plate 24 from moving to the right, so that the rack plate 24 drives the second fixing block 22 and the right plate 1 to be tightly connected with the left plate 1.

[0033] like Figure 3 and Figure 5 As shown, the top of the lifting block 280 has a shaft groove, and a bearing 285 is fixedly installed in the shaft groove. The bottom end of the second handle 29 is fixedly connected to the inner ring wall of the bearing 285. The bearing 285 can rotate the bottom end of the second handle 29 to the top of the lifting block 280. When the second handle 29 rotates in a threaded manner, it can drive the limiting component 28 to move up and down in the storage slot 27. When the limiting component 28 moves up until the limiting block 283 disengages from the limiting tooth groove 242 on the top of the rack plate 24, the rack plate 24 is no longer constrained. Then, the first handle 26 is rotated in the opposite direction to drive the transmission gear 25 to mesh with the gear groove 241 and rotate, thereby causing the rack plate 24 to move to the right. In this way, the two plates 1 can be separated with manual assistance.

[0034] like Figure 3 , Figure 4 and Figure 5As shown, the top of the second fixing block 22 has a first through hole 210, and the right end of the rack plate 24 has a second through hole 211 that runs vertically through and is aligned with the first through hole 210. A first bolt 212 is inserted between the first through hole 210 and the second through hole 211. The position of the rack plate 24 can be fixed inside the second fixing block 22 by the first bolt 212. The baffle 23 at the right end of the rack plate 24 plays a positioning role. When the baffle 23 is attached to the right side of the second fixing block 22, the first through hole 210 on the second fixing block 22 is aligned with the second through hole 211 on the rack plate 24. Then the first bolt 212 can be inserted.

[0035] like Figure 1 and Figure 2 As shown, each of the four corners of the side of the first fixing block 21 and the second fixing block 22 is fixedly installed with a hanging ear 4. Each hanging ear 4 is connected to the plate 1 by a threaded bolt. The first fixing block 21 and the second fixing block 22 can be installed on the front side of the two plates 1 respectively through the hanging ear 4, and the installation height of the first fixing block 21 and the second fixing block 22 must be consistent.

[0036] like Figure 1 and Figure 6 As shown, the snap-fit ​​mechanism 3 includes a plug plate 31 and a connecting plate 32. The plug plate 31 is fixedly installed on the front side of the right plate 1, and the connecting plate 32 is fixedly installed on the front side of the left plate 1. The connecting plate 32 is C-shaped, and the left end of the plug plate 31 can be inserted between the connecting plates 32. The snap-fit ​​mechanism 3 can enhance the connection stability of the top and bottom of the two plates 1 at the docking ends.

[0037] like Figure 6 and Figure 7 As shown, the top and bottom of the left end of the plug-in plate 31 are provided with second grooves 34. Each of the two second grooves 34 is movably inserted with a locking block 35. Both sides of the locking block 35 extending out of the second groove 34 are set as bevels. A second spring 36 is fixedly connected between the inner end of the two second grooves 34 and the corresponding locking block 35. The top and bottom of the inner wall of the connecting plate 32 are provided with slots 33 that are adapted to the shape of the beveled end of the locking block 35. When the left end of the plug-in plate 31 is inserted between the connecting plates 32, the parts of the two locking blocks 35 extending out of the second grooves 34 are respectively engaged in the two slots 33. When the locking block 35 is squeezed by external force, it will move into the second groove 34. When the locking block 35 is not constrained by the second bolt 39, the plug-in plate 31 and the connecting plate 32 can be arbitrarily connected or separated.

[0038] like Figure 6 and Figure 7As shown, each locking block 35 has a first threaded hole 37 extending from front to back on its side. The front side of the left end of the plug-in plate 31 has two second threaded holes 38 that communicate with the second groove 34. When the locking block 35 is engaged in the slot 33, the first threaded hole 37 on the locking block 35 is aligned with the corresponding second threaded hole 38, and a second bolt 39 is threaded between the first threaded hole 37 and the second threaded hole 38. When the second bolt 39 passes through the second threaded hole 38 and is inserted into the first threaded hole 37 on the locking block 35, the locking block 35 cannot move into the second groove 34, thereby making the locking block 35 stably engaged in the slot 33, and thus preventing the plug-in plate 31 from separating from the connecting plate 32.

[0039] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
