Description

Technical Field

[0001] This utility model relates to the field of electric door technology, and in particular to a quick-release structure for vertical bars, a door panel assembly, and a drop-down door. Background Technology

[0002] Airlock gates are widely used at highway toll stations, parking lots, residential communities, and enterprise entrances to facilitate the orderly management of vehicle access. They can also be heightened for use at villa and courtyard entrances for security purposes. An airlock gate consists of a housing and a gate assembly. The gate assembly includes a front beam and a bottom beam positioned opposite each other, along with several vertical bars positioned between them. The ends of the vertical bars are rotatably connected to the front and bottom beams. A drive mechanism within the housing raises and lowers the gate assembly. When the gate assembly rises, the front and bottom beams rotate relative to each other, causing the vertical bars to tilt. When the gate assembly lowers, the front and bottom beams rotate relative to each other, causing the vertical bars to be perpendicular to the front and bottom beams. Thus, the airlock gate opens by raising the gate assembly, which then folds back into the housing. The gate closes by lowering the gate assembly, which then lays horizontally on the ground.

[0003] Current airlock gate structures feature horizontally penetrating mounting holes at both ends of the vertical rod, which are rotatably connected to the top and bottom beams via connecting seats. Specifically, a fixing pin passes sequentially through the connecting hole of the connecting seat and the mounting hole of the vertical rod, and then fasteners are used to secure the cover to the end of the fixing pin, thus achieving a rotatable connection between the connecting seat and the vertical rod. The mounting holes at both ends of the vertical rod are typically formed by stamping; however, the vertical rod is generally a hollow tube structure made of aluminum profile, which is prone to deformation during the stamping process, affecting the structural strength of the vertical rod and the assembly effect between the vertical rod and the connecting seat.

[0034] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0037] See Figure 2-4 This utility model provides a quick-assembly and disassembly structure for vertical rods, including: two mounting beams 1 arranged at relative intervals, and a plurality of vertical rods 2 spaced apart between the two mounting beams 1 along their length direction. Both ends of the vertical rods 2 are rotatably mounted on the two mounting beams 1 through connecting blocks 3, and the vertical rods 2 are plugged into the connecting blocks 3.

[0038] by Figure 2The directions shown are referenced, with x representing the length and y representing the width. Two mounting beams 1 are arranged parallel to each other, and several vertical rods 2 are rotatably mounted on the mounting beams 1 along their length. If the vertical rods 2 are directly rotatably connected to the mounting beams 1, holes need to be punched at the ends of the vertical rods 2 to achieve assembly between the vertical rods 2 and the mounting beams 1. However, the vertical rods 2 are generally hollow tube structures made of aluminum profiles, which are prone to deformation during the stamping process, thus affecting the structural strength of the vertical rods 2 and the assembly effect between the vertical rods 2 and the mounting beams 1.

[0039] This invention features a connecting block 3 between the vertical rod 2 and the mounting beam 1. The vertical rod 2 and the connecting block 3 are plugged into each other. When the vertical rod 2 needs to be rotatably installed on the mounting beam 1, the vertical rod 2 and the connecting block 3 can be pre-installed by plugging them together, and then the connecting block 3 can be rotated and installed on the mounting beam 1. When the vertical rod 2 needs to be removed for maintenance or replacement, the connecting block 3 can be directly disassembled from the mounting beam 1, thus enabling quick assembly and disassembly of the vertical rod 2 on the mounting beam 1. Furthermore, the connecting block 3 prevents deformation of the vertical rod 2 and weakening of structural strength caused by punching, ensuring the assembly strength of the vertical rod 2 and the mounting beam 1.

[0040] The vertical rod 2 and the connecting block 3 can be connected by inserting the connecting block 3 with a groove structure, and the corresponding end of the vertical rod 2 with a matching protruding structure. Inserting the protruding structure into the groove structure achieves the insertion of the vertical rod 2 and the connecting block 3. (See also: [reference needed]) Figure 4 Both ends of the vertical rod 2 are provided with mounting slots 21. The connecting block 3 is provided with a matching mounting block 311 corresponding to the mounting slot 21, and the mounting block 311 is inserted into the mounting slot 21. During assembly, the mounting slot 21 and the mounting block 311 are inserted and connected to achieve the connection between the vertical rod 2 and the connecting block 3. Then, the connecting block 3 and the mounting beam 1 are rotated and installed to achieve the quick installation of the vertical rod 2 and the mounting beam 1. During disassembly, the connecting block 3 and the mounting beam 1 are directly disassembled and separated to achieve the separation of the vertical rod 2 and the mounting beam 1.

[0041] It is worth noting that the mounting block 311 is inserted into the mounting groove 21, and the connection between the vertical rod 2 and the connecting block 3 needs to be kept firm when the vertical rod 2 and the connecting block 3 rotate relative to the mounting beam 1.

[0042] Based on this, see Figure 6-7 The side wall of the mounting block 311 is provided with a slot 3111, and the inner wall of the mounting groove 21 is provided with a locking block 22 corresponding to the slot 3111. In the assembled state, the locking block 22 is locked in the slot 3111. In this way, the locking block 22 and the slot 3111 can be used to achieve a stable connection between the connecting block 3 and the vertical rod 2.

[0043] The locking block 22 is formed by stamping inward through the groove wall of the mounting groove 21. In the assembled state, the locking block 22 abuts against the groove wall of the slot 3111 near the insertion end of the mounting block 311. The stamping process of the locking block 22 is simple and ensures that the locking block 22 and the vertical rod 2 are an integral structure, preventing the locking block 22 from detaching from the vertical rod 2 and affecting the fixing effect. When the vertical rod 2 is separated from the connecting block 3, the locking block 22 is not stamped on the vertical rod 2. After the mounting block 311 of the connecting block 3 is inserted into the end of the vertical rod 2, the corresponding position of the vertical rod 2 is stamped to form the locking block 22, which is locked in the slot 3111, thereby completing the stable installation of the connecting block 3 and the vertical rod 2. Since both the vertical rod 2 and the connecting block 3 are rigid structures, the fitting and insertion of the mounting block 311 into the mounting groove 21, combined with the locking of the locking block 22 into the slot 3111, ensures the firmness of the installation of the connecting block 3 and the vertical rod 2. Furthermore, when the vertical rod 2 is stamped to form the locking block 22, an installation block 311 is inserted into the vertical rod 2, which can prevent the deformation of the vertical rod 2 caused by stamping, thereby ensuring the strength of the vertical rod 2 and its assembly structure.

[0044] The side wall of the insertion end of the mounting block 311 and / or the groove wall of the slot 3111 away from the insertion end of the mounting block 311 are provided with inclined structures 3112, which are formed by the inward inclination of the side wall of the mounting block 311. When the mounting block 311 is inserted into the mounting groove 21 and presses against the side wall of the vertical rod 2, the inclined structure 3112 can reduce damage to the vertical rod 2 and prevent deformation of the vertical rod 2. Furthermore, the inclined structure 3112 can reduce the contact area between the side wall of the mounting block 311 and the inner wall of the mounting groove 21, thereby improving the smoothness of the insertion of the connecting block 3 and the vertical rod 2.

[0045] Furthermore, the mounting block 311 has several perforated holes 3113, which are designed to avoid the slots 3111. The perforated holes 3113 help reduce the weight of the connecting block 3, thereby reducing the weight of the entire assembly. The perforated holes 3113 need to avoid the slots 3111 to ensure the overall strength of the mounting block 311, thereby improving its installation strength with the vertical rod 2.

[0046] Based on the above structure, see [link / reference] Figure 3-5 Mounting beam 1 is provided with mounting ears 11 corresponding to connecting block 3. Connecting block 3 includes plug-in block 31 and mating block 32 which is detachably connected to plug-in block 31 and is disposed opposite to it. Plug-in block 31 includes mounting block 311 inserted into mounting groove 21 and rotating block 312 located outside mounting groove 21. Rotating block 312 and mating block 32 are respectively disposed on both sides of mounting ear 11 and rotatably connected to mounting ear 11. Mounting ear 11 is fixedly installed on mounting beam 1. Mounting ear 11 and mounting beam 1 can be integrally formed, or they can be connected by welding, bonding, snap-fitting, screwing, etc., to form a detachable structure, as long as the reliability of the connection between mounting ear 11 and mounting beam 1 can be guaranteed.

[0047] Rotating block 312 and mating block 32 extend towards each other to form a first connecting shaft 3121 and a second connecting shaft 321, respectively. Mounting ear 11 is provided with mounting holes 111 that rotatably engage with the first connecting shaft 3121 and the second connecting shaft 321, and the mounting holes 111 extend through the mounting ear 11 in the width direction. Connecting block 3 includes two parts: a plug-in block 31 and a mating block 32, dividing the connecting shaft into a first connecting shaft 3121 and a second connecting shaft 321. When the first connecting shaft 3121 and the second connecting shaft 321 are rotatably inserted into the mounting holes 111, the relative connection relationship between the plug-in block 31 and the mating block 32 fixes the positions of the first connecting shaft 3121 and the second connecting shaft 321, resulting in a small gap. This prevents the first connecting shaft 3121 and the second connecting shaft 321 from easily disengaging from the mounting holes 111, thereby improving the reliability of the connection between connecting block 3 and mounting ear 11.

[0048] Furthermore, the side wall of the rotating block 312 is provided with a first through hole 3122 corresponding to the first connecting shaft 3121, and the side wall of the mating block 32 is provided with a second through hole 322 corresponding to the second connecting shaft 321. The axes of the first through hole 3122, the first connecting shaft 3121, the second connecting shaft 321, and the second through hole 322 coincide. The first connecting shaft 3121 and the second connecting shaft 321 are connected by fasteners 33 that penetrate axially therein. The first through hole 3122 and the second through hole 322 are provided with matching sealing members 34. After the first connecting shaft 3121 and the second connecting shaft 321 are rotatably inserted into the mounting hole 111, the first connecting shaft 3121 and the second connecting shaft 321 are locked by the fasteners 33, and the sealing members 34 are filled into the first through hole 3122 and the second through hole 322. This can further improve the reliability of the connection between the connecting block 3 and the mounting ear 11, and the setting of the sealing member 34 helps to improve the aesthetics of the assembly structure.

[0049] Among them, fastener 33 can be a common screw, pin, or other structure. Sealing component 34 can be a rubber gasket, which has the function of sealing and filling.

[0050] Regarding the relative connection structure between the rotating block 312 and the mating block 32, in this utility model, the rotating block 312 and the mating block 32 are slidably inserted into each other. (See reference...) Figure 6 and Figure 7The rotating block 312 has a first sliding groove 3123 at the exposed end of the mounting block 311, and a first slider 3124 extends in opposite directions along the length of the end of the first sliding groove 3123 away from the mounting block 311. The mating block 32 has a matching second sliding groove 323 corresponding to the first slider 3124, and a matching second slider 324 extends in opposite directions along the length of the end of the second sliding groove 323 near the mounting block 311. During installation, the mounting block 311 is inserted into the mounting groove 21, and the first connecting shaft 3121 of the insertion block 31 and the second connecting shaft 321 of the mating block 32 are inserted into the mounting hole facing each other. At the same time, the mating block 32 and the rotating block 312 are slidably inserted into each other, so that the first slider 3124 is inserted into the second sliding groove 323 and the second slider 324 is inserted into the first sliding groove 3123, thereby realizing the installation of the connecting block 3 and the mounting ear 11.

[0051] For the assembly of vertical rod 2 and mounting beam 1, the two ends of vertical rod 2 are generally connected to opposite sides of the two mounting beams 1. Alternatively, the two ends of vertical rod 2 can be installed on the same side of the width direction of the two mounting beams 1. There are various installation positions for vertical rod 2, which can be selected according to actual needs. Based on this, refer to... Figure 3 The mounting ear 11 is located on the end face of the mounting beam 1 facing another mounting beam 1, and / or, the mounting ear 11 is located on the side of the mounting beam 1 in the width direction. The mounting ear 11 is selected at the mounting beam 1 according to the requirements of the vertical rod 2's installation position, thereby enabling the vertical rod 2 to be rotated relative to the mounting beam 1 through the rotational connection between the mounting ear 11 and the connecting block 3.

[0052] See Figure 2 and Figure 3 This utility model also provides a gate assembly, including the aforementioned quick-release structure for vertical bars. The gate assembly has a lifting function. During the lifting process, the two mounting beams 1 rotate synchronously, and a plurality of vertical bars 2 rotate relative to the two mounting beams 1, so that when the gate assembly is lowered to the ground, both mounting beams 1 are in a horizontal state, and the plurality of vertical bars 2 are perpendicular to the mounting beams 1; after the gate assembly is raised, the two mounting beams 1 are in a vertical state, and the plurality of vertical bars 2 are inclined relative to the mounting beams 1.

[0053] The gate assembly of this utility model includes the above-mentioned quick-assembly and disassembly structure for the vertical rod. During installation, the connecting block 3 and the vertical rod 2 can be pre-assembled, and then the connecting block 3 and the mounting ear 11 can be rotated and installed accordingly. This enables the quick assembly of the gate assembly. Furthermore, when it is necessary to disassemble the gate assembly or replace or repair the vertical rod, the connecting block 3 and the mounting ear 11 can be directly separated, which greatly improves the disassembly and assembly efficiency of the gate assembly.

[0054] See Figure 1The present invention also provides an air-drop door, including: a housing 4 and the aforementioned door assembly. The housing 4 is provided with a drive mechanism connected to the door assembly. The drive mechanism can drive the door assembly to rotate in a vertical plane to raise or lower.

[0055] The airlock door is raised or lowered by a drive mechanism inside the housing 4. When raised, the door assembly folds up at the housing 4 to open the door; when lowered, it unfolds flat on the ground to close the door. This structure allows for rapid assembly of the door assembly, accelerating the assembly process between the door assembly and the housing 4 and significantly improving the assembly efficiency of the airlock door. Simultaneously, the connecting block 3 prevents deformation of the vertical rod 2 and weakening of structural strength caused by punching, thus ensuring the structural strength of the door assembly and guaranteeing the service life of the airlock door during frequent opening and closing operations.

[0056] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
