Description

Technical Field

[0001] This utility model belongs to the field of floodproof door sealing technology, specifically a thresholdless floodproof door with a split lock head pressing down bearing sealing beam structure. Background Technology

[0002] The door frame of a floodproof door supports the door leaf by bearing the load around the door leaf through components such as pressure strips / thresholds. When the floodproof door is flooded, the door leaf will bear the force first. When bearing the force, the door leaf and the door frame must be locked together to transfer the force to the door frame. In order to increase the load-bearing capacity of the door frame, a sealing beam structure is added to the door leaf to seal with the door frame / threshold. However, the conventional sealing beam structure and the locking structure of the lower frame and threshold are not strong enough to withstand the impact force of 12560KN. In severe cases, it may lead to the risk of the door leaf being blown away from the door frame.

[0003] Most existing floodgate locks are one-piece structures. After years of resisting floodwater, the locks will suffer varying degrees of damage, requiring the replacement of the entire lock, which greatly increases the cost of flood prevention. Therefore, there is an urgent need to design a thresholdless floodgate with a split lock head and a pressure-bearing sealing beam structure to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a thresholdless floodproof door with a split lock head and a pressure-bearing sealing beam structure, which solves the problem that the conventional sealing beam structure and the locking structure of the lower frame threshold are not firm and cannot withstand the impact force of 12560KN, which may lead to the door leaf being blown away from the door frame in severe cases.

[0005] Over the years, lock cylinders will inevitably suffer varying degrees of damage from debris, necessitating the replacement of the entire lock cylinder, which significantly increases the cost of prevention.

[0006] To solve the above-mentioned technical problems, this utility model provides a thresholdless floodproof door with a split lock head and a pressure-bearing sealing beam structure. The door includes a door frame, door leaves, a sealing beam structure, and a lock head structure. The door frame is a recessed door frame, with a mating groove on the lower frame. There are two door leaves, each connected to one of the side frames of the door frame via hinges. Several guide brackets are spaced apart on the back of each of the two door leaves.

[0007] The lock head structure consists of two sets, and the fixed ends of the two sets of lock head structures are connected to the inner side of the upper frame of the door frame. The lock head of each set of lock head structures passes through the guide bracket on the back of the corresponding door leaf and is connected to a connecting plate. The bottom of each connecting plate is provided with a corresponding sealing beam structure, and each sealing beam structure is slidably connected to the back of the corresponding door leaf. When the connecting plate is subjected to the downward pressure of the lock head structure, it drives the sealing beam structure to extend downward into the mating groove and lock.

[0008] Furthermore, several door frame lower fixing components are embedded in the ground below the lower frame of the door frame. Each door frame lower fixing component includes a support frame and a support reinforcing rib embedded in the ground. The top surface of the support frame abuts against the lower surface of the lower frame of the door frame. The support reinforcing ribs are a pair and are symmetrically arranged on both sides of the support frame. Each pair of support reinforcing ribs is fixedly arranged on the two side walls that are vertically arranged on the outer wall of the support frame.

[0009] Furthermore, each of the sealing beam structures includes a movable plate, a sealing beam, and a support plate. The movable plate is slidably connected to the back of the door leaf and fixed to one side of the sealing beam. The support plate is fixedly disposed on the side of the sealing beam away from the movable plate and is used to fit against and support the upper surface of the lower frame of the door frame. The top of the sealing beam is fixedly connected to the connecting plate. The lower two sides of the sealing beam are respectively provided with a first inclined wall and a second inclined wall, the height of the second inclined wall being less than the height of the first inclined wall.

[0010] The mating groove includes a first stop section, a second stop section, and a sealing section arranged sequentially. The inner wall of one side of the first stop section is provided with a third inclined wall, which cooperates with and limits the first inclined wall. The width of the second stop section is greater than the width of the bottom of the sealing beam and less than the distance between the first inclined wall and the vertical wall above the second inclined wall. The second stop section and the sealing section are provided with sealing elements.

[0011] Furthermore, a number of reinforcing ribs are provided between the support plate and the connecting plate, and the connecting plate, the movable plate, the sealing beam, the support plate and the number of reinforcing ribs are integrally formed.

[0012] Furthermore, each of the lock head structures includes a telescopic cylinder, an upper locking head, a lower locking head, and a limiting bolt. The telescopic cylinder is connected to the upper frame of the door frame. The upper end of the upper locking head is connected to the telescopic cylinder, and the lower end is hinged to the lower locking head. The lower locking head passes through the corresponding guide bracket and is connected to the connecting plate. Each guide bracket is embedded with a limiting sleeve. The side wall of the limiting sleeve has a first waist-shaped groove that penetrates both side walls. The outer side wall of the lower locking head has a second waist-shaped groove. The limiting bolt passes through the guide bracket and the first waist-shaped groove, and its inner end engages with the second waist-shaped groove.

[0013] The beneficial effects of this utility model are as follows: The thresholdless floodproof door of this utility model guides the locking direction of the lock head structure through the corresponding guide bracket, which improves the stability of the locking path of the lock head structure. At the same time, the lock head of the lock head structure locks with the matching groove on the lower frame of the door frame to strengthen the resistance of the door leaf and the door frame, so that it can meet the requirement of resisting the impact force of 12560KN.

[0014] The installation of the door frame lower fixing component involves burying the door frame lower fixing component in the ground and abutting the lower surface of the door frame lower frame against it. The lower frame of the door frame is fixed to the top surface of the support frame of the door frame lower fixing component by fasteners, thereby effectively improving the stability of the lower frame of the door frame and strengthening the resistance of the door frame.

[0015] The sealing beam structure is designed to prevent the sealing beam from moving further into the sealing section by engaging with the mating groove in the lower part of the sealing beam and the lower frame of the door frame through a double stop limit. At the same time, the sealing elements in the second stop section and the sealing section can effectively form a good seal with the lower part of the sealing beam to improve the sealing performance of the lower edge of the floodproof door.

[0016] The lock head structure is designed so that the output shaft of the telescopic cylinder drives the upper locking head to move up or down, thereby causing the lower locking head to move up or down within the limiting sleeve. The inner end of the limiting bolt, which passes through the guide bracket, achieves maximum limitation with the upper and lower groove walls of the second oblong groove on the lower locking head, so as to avoid the lower locking head moving downward without restriction due to wear of the mating groove. This solves the problem that existing lock heads are prone to detaching from the threshold due to years of resisting erosion, and also solves the problem that existing one-piece lock heads need to be replaced as a whole when damaged.

Detailed Implementation

[0026] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] In one specific embodiment of this utility model, such as Figure 1-7 As shown, a thresholdless floodproof door with a split lock head and a pressure-bearing sealing beam structure is disclosed. It includes a door frame 1, door leaves 2, a sealing beam structure 3, and a lock head structure 4. The door frame 1 is a recessed door frame, with a mating groove 111 on the lower frame 11. There are two door leaves 2, each connected to the side frames 12 of the door frame 1 via hinges. Several guide brackets 7 are spaced apart on the back of each of the two door leaves 2.

[0028] The lock head structure 4 consists of two sets, and the fixed ends of the two sets of lock head structures 4 are connected to the inner side of the upper frame of the door frame 1. The lock head of each set of lock head structures 4 passes through the guide bracket 7 on the back of the corresponding door leaf 2 and is connected to a connecting plate 52. Each connecting plate 52 has a corresponding sealing beam structure 3 at its bottom, and each sealing beam structure 3 is slidably connected to the back of the corresponding door leaf 2. When the connecting plate 52 is subjected to the downward pressure of the lock head structure 4, it drives the sealing beam structure 3 to extend downward into the mating groove 111 and lock.

[0029] The thresholdless floodproof door guides the locking direction of the lock head structure 4 through the corresponding guide bracket 7, improving the stability of the locking path of the lock head structure 4. At the same time, the lock head of the lock head structure 4 locks with the mating groove 111 on the lower frame 11 of the door frame 1 to strengthen the resistance of the door leaf 2 and the door frame 1, so that it can meet the requirement of resisting the impact force of 12560KN.

[0030] The backs of the two door panels 2 are also equipped with several inclined support devices 5 at intervals, and each of the inclined support devices 5 is arranged one-to-one between two adjacent guide brackets 7.

[0031] A number of door frame lower fixing components 6 are embedded in the ground below the lower frame 11 of the door frame 1. Each door frame lower fixing component 6 includes a support frame 61 and a support reinforcing rib 62 embedded in the ground. The top surface of the support frame 61 abuts against the lower surface of the lower frame 11 of the door frame 1. The support reinforcing ribs 62 are a pair and are symmetrically arranged on both sides of the support frame 61. Each pair of support reinforcing ribs 62 is fixedly arranged on the two side walls that are vertically arranged on the outer wall of the support frame 61.

[0032] The door frame lower fixing component 6 is installed in the ground and the lower surface of the lower frame 11 of the door frame 1 abuts against it. The lower frame 11 of the door frame 1 is fixed to the top surface of the support frame 61 of the door frame lower fixing component 6 by fasteners, thereby effectively improving the stability of the lower frame 11 of the door frame 1 and strengthening the resistance of the door frame 1.

[0033] Each sealing beam structure 3 includes a movable plate 31, a sealing beam 32, and a support plate 33. The movable plate 31 is slidably connected to the back of the door leaf 2 and fixed to one side of the sealing beam 32. The support plate 33 is fixedly disposed on the side of the sealing beam 32 away from the movable plate 31. The support plate 33 is used to fit and support the upper surface of the lower frame 11 of the door frame 1. The top of the sealing beam 32 is fixedly connected to the connecting plate 52. The lower two sides of the sealing beam 32 are respectively provided with a first inclined wall 321 and a second inclined wall 322. The height of the second inclined wall 322 is less than the height of the first inclined wall 321.

[0034] The mating groove 111 includes a first stop section 1111, a second stop section 1112, and a sealing section 1113 arranged sequentially. The inner wall of one side of the first stop section 1111 is provided with a third inclined wall 11111. The third inclined wall 11111 cooperates with the first inclined wall 321 for limiting. The width of the second stop section 1112 is greater than the width of the bottom of the sealing beam 32 and less than the distance between the vertical wall above the first inclined wall 321 and the second inclined wall 322. The second stop section 1112 and the sealing section 1113 are provided with sealing elements 34.

[0035] The sealing beam structure 3 is designed so that the lower part of the sealing beam 32 cooperates with the mating groove 111 in the lower frame 11 of the door frame 1, and the sealing beam 32 is prevented from moving further to the sealing section 1113 by means of double stop limit. At the same time, the sealing element 34 in the second stop section 1112 and the sealing section 1113 can effectively form a good seal with the lower part of the sealing beam 32, so as to improve the sealing performance of the lower edge of the floodproof door.

[0036] Several reinforcing ribs 35 are provided between the support plate 33 and the connecting plate 52. The connecting plate 52, the moving plate 31, the sealing beam 32, the support plate 33 and the several reinforcing ribs 35 are integrally formed. The above-mentioned integrally formed structure can effectively improve the sealing stability between the sealing beam structure and the lower frame of the door frame.

[0037] Each lock structure 4 includes a telescopic cylinder, an upper locking head 42, a lower locking head 43, and a limiting bolt 44. The telescopic cylinder is connected to the upper frame of the door frame 1. The upper end of the upper locking head 42 is connected to the telescopic cylinder, and the lower end is hinged to the lower locking head 43. The lower locking head 43 passes through the corresponding guide bracket 7 and is connected to the connecting plate 52. Each guide bracket 7 is embedded with a limiting sleeve. The side wall of the limiting sleeve is provided with a first waist-shaped groove 411 that penetrates both side walls. The outer side wall of the lower locking head 43 is provided with a second waist-shaped groove 431. The limiting bolt 44 passes through the guide bracket 7 and the first waist-shaped groove 411, and its inner end cooperates with the second waist-shaped groove 431.

[0038] The lock head structure 4 is designed so that the output shaft of the telescopic cylinder drives the upper locking head 42 to move up or down, thereby driving the lower locking head 43 to move up or down within the limiting sleeve. The inner end of the limiting bolt 44, which passes through the guide bracket 7, achieves maximum limiting with the upper and lower groove walls of the second waist-shaped groove 431 on the lower locking head 43, so as to avoid the lower locking head 43 from moving down without restriction due to wear of the mating groove 111. This solves the problem that existing lock heads are prone to detaching from the threshold due to constant resistance to erosion, and also solves the problem that existing one-piece lock heads need to be replaced as a whole when damaged.

[0039] The working process of this utility model:

[0040] Each pair of supporting reinforcing ribs 62 of the lower fixing component 6 of the door frame is fixed to the mutually perpendicular upper bottom surface and vertical surface of the outer wall of the support frame 61. The fixed support frame 61 is buried in the ground at intervals. A recessed groove is set above several parallel support frames 61. The door frame 1 is placed in the recessed groove. The bottom of the lower frame 11 of the door frame 1 is attached to the upper top surface of several support frames 61 and fixed with multiple fasteners. The door leaf 2 is then installed on the door frame 11. Several lock head structures 4 are installed on the inner wall of the upper frame of the door frame 1 on the back of each door leaf 2.

[0041] When the lower locking head needs to be locked, the telescopic cylinders of several lock head structures 4 connected to the inner side of the upper frame of the door frame 1 extend downward simultaneously to push the upper locking head 42 downward. After being subjected to downward force, the lower locking head 43 moves downward along the limiting sleeves in the corresponding guide brackets 7 fixed to the back of the two door leaves 2. The connecting plate 52 moves downward accordingly, and the sealing beam structure 3 integrally formed with the connecting plate 52 moves downward at the same time. The first inclined wall 321 at the lower part of the sealing beam 32 moves downward along the third inclined wall 11111 on one side of the first stop section 1111 of the mating groove 111. The third inclined wall 11111 of the first stop section 1111 engages with the inclined surface of the first inclined wall 321 for limiting. The reaction force of the third inclined wall 11111 is used to perform the first stop on the lower part of the sealing beam 32. When the sealing beam 32 or the mating groove 111 is worn, the second stop section 1112 uses its width to limit the width of the vertical wall above the first inclined wall 321 and the second inclined wall 322 by using its width to limit the width of the vertical wall above the first inclined wall 321 and the second inclined wall 322 of the sealing beam 32, so as to achieve the second limit. When the limit is completed, the sealing element 34 in the second stop section 1112 and the sealing section 11113 forms a seal with the lower part of the sealing beam 32, so as to improve the stability and sealing of the locking between the sealing beam structure 3 and the mating groove 111 of the lower frame 11 of the door frame 1.

[0042] When the lower locking head needs to be unlocked, the telescopic cylinders of several lock head structures 4 connected to the inner side of the upper frame of the door frame 1 are simultaneously lifted upward to drive the upper locking head 42 to move upward. After the lower locking head 43 is subjected to upward pulling force, it moves upward along the limit sleeves in the corresponding guide brackets 7 fixed on the back of the two door leaves 2 respectively. The connecting plate 52 moves upward accordingly, and the sealing beam structure 3 integrally formed with the connecting plate 52 moves upward at the same time. The lower part of the sealing beam 32 disengages from the seal in the mating groove 111.

[0043] When the sealing beam 32 or the mating groove 111 is worn, the sealing beam 32 will continue to move into the mating groove 111 during the locking process. When the inner end of the limiting bolt 44 on the guide bracket 7 abuts against the upper groove wall of the second waist-shaped groove 431 on the lower locking head 43, the sealing beam 32 can be controlled to move downward to the maximum extent. This effectively controls the maximum downward position of the sealing beam 32 to avoid the risk of the sealing beam 32 colliding with the bottom surface of the sealing section 11113, thereby improving the service life of the lock head structure 4.

[0044] The lock head structure 4 of this application adopts a split connection method, which allows for the replacement of local parts, thus greatly reducing the cost of security measures.

[0045] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
