Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0022] Example
[0023] Please see Figure 1 , Figure 2 and Figure 5 A two-way multi-point locking door includes a door frame 1. Two hinge mechanisms 9 are symmetrically arranged on the upper and lower right side of the door frame 1, and a door body 3 is installed between the two hinge mechanisms 9. An installation groove 11 is opened in the upper part of the door body 3, and a two-way locking mechanism 5 is installed inside the installation groove 11. A door lock 4 is fixedly installed on the left side of the middle part of the door body 3, and a rubber sealing ring 2 is provided between the door body 3 and the door frame 1. The door body 3 is hollow inside, and a vertical partition 6 and several horizontal partitions 7 are fixedly connected to the hollow part. The horizontal partitions 7 and the vertical partitions 6 are distributed at a 90-degree angle. The vertical partitions 6 and the horizontal partitions 7 divide the interior of the door body 3 into several cavities, and each cavity is provided with a heat insulation layer 8.
[0024] In use, this utility model utilizes a hinge mechanism 9 to achieve hinged installation of the door body 3, facilitating bidirectional opening and closing of the door body 3. A bidirectional locking mechanism 5 achieves locking and fixing of the door body 3 at both the top and bottom points, and in conjunction with the door lock 4, achieves multi-point locking and fixing of the door body 3, improving security. Horizontal partition 7 and vertical partition 6 are used to enhance the structural strength of the door body 3. Thermal insulation layer 8 is used to improve the thermal insulation capacity of the door body 3. The thermal insulation layer 8 is a polyurethane foam filling layer. Rubber sealing ring 2 is used to achieve sealing and dust prevention between the door body 3 and the door frame 1.
[0025] Please see Figure 2 , Figure 3 and Figure 4The hinge mechanism 9 includes two second fixing plates 91 that are symmetrically fixed to the inner wall of the right side of the door frame 1. Each of the two second fixing plates 91 is fixedly connected to a second mounting plate 94 on its left side. A metal pulley 93 is rotatably passed through the second mounting plate 94. Each of the two metal pulleys 93 is fixedly connected to a mounting shaft 96 on one side. Each of the two mounting shafts 96 is fixedly connected to a pad 95 on the side of the two mounting shafts that are close to each other. The door body 3 is fixedly connected between the two pads 95. Two reinforcing ribs 92 are symmetrically fixed between the second fixing plate 91 and the second mounting plate 94.
[0026] The second fixing plate 91 is used to fix the second mounting plate 94. The reinforcing rib plate 92 is used to enhance the structural strength between the second fixing plate 91 and the second mounting plate 94. The metal pulley 93 and the mounting shaft 96 are used to realize the rotational connection between the second mounting plate 94 and the door body 3. Compared with the ordinary hinge connection, this connection method has a higher degree of freedom and makes it easier to open and close the door body 3 in two directions.
[0027] Please see Figure 1 , Figure 5 and Figure 6 The bidirectional locking mechanism 5 includes a locking head 51, a fixing rod 52, and a drive assembly 53. The fixing rod 52 is mounted on the drive assembly 53. The drive assembly 53 includes two mounting plates 531 that are symmetrically fixedly connected to the inside of the mounting groove 11. A lock cylinder 533 is fixedly connected to the middle of each of the two mounting plates 531. A fixing plate 534 is fixedly sleeved in the middle of each of the two lock cylinders 533. The fixing plate 534 is fixedly connected to the inside of the mounting groove 11. A connecting shaft 532 is fixedly connected between the rotating parts of the two lock cylinders 533. A gear 536 is fixedly sleeved in the middle of the connecting shaft 532.
[0028] Please see Figure 5 and Figure 6 The mounting groove 11 has two guide rods 54 fixedly connected symmetrically on the left and right sides. Each guide rod 54 has two limiting blocks 55 slidably sleeved on it. The two limiting blocks 55 on the same guide rod 54 are fixedly connected to a rack 535. Both racks 535 mesh with gears 536. Each rack 535 is fixedly connected to a fixing rod 52. The two fixing rods 52 are centrally symmetrically distributed. The two fixing rods 52 slide through the top and bottom of the door body 3 respectively. After sliding through the door body 3, both fixing rods 52 are fixedly connected to a locking head 51. The top and bottom surfaces inside the door frame 1 are provided with locking grooves 10 that cooperate with the locking heads 51.
[0029] When it is necessary to lock or unlock the door body 3, first use the door lock 4 to lock it. Then, insert the corresponding key into the keyhole inside the lock cylinder 533 in the two-way locking mechanism 5. At this time, rotate the key to drive the corresponding rotating part in the lock cylinder 533 to rotate, which in turn drives the connecting shaft 532 and the gear 536 on it to rotate. At the same time, it drives the two racks 535 to move away from the gear 536, which in turn drives the fixed rod 52 and the locking head 51 on it to move away from the gear 536 until the locking head 51 is locked into the locking groove 10. Reverse the key to unlock it. With the locking of the door lock 4, multi-point locking is achieved, the locking effect is good, and the security of the door body 3 is improved.
[0030] It should be noted that, in the use of this type of two-way multi-point locking door, the pad 95 in the hinge mechanism 9 is first fixedly connected to the top and bottom of the door body 3, and then the second fixing plate 91 in the hinge mechanism 9 is fixedly connected to the door frame 1 with bolts, thus realizing the installation of the door body 3. Compared with ordinary hinges, the hinge mechanism 9 has a higher degree of freedom, which is conducive to realizing two-way opening and closing. The horizontal partition 7 and vertical partition 6 inside the door body 3 enhance the structural strength of the door body 3, and the thermal insulation layer 8 improves the thermal insulation capacity of the door body 3. The two-way locking mechanism 5 is used to realize the upper and lower two-point locking of the door body 3. With the use of the door lock 4, multi-point locking is realized.
[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
