[0036] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.

[0040] For ease of explanation, this embodiment exemplifies the structure of the door leaf when used as a room door. However, the multi-lock pin structure door of this patent is not limited to use as a house door, and can also be used in cabinets, boxes, and other occasions with openable and closable door leaves.

[0041] Typical door structure, such as Figure 1 As shown: It includes a door frame 8 and a door leaf 9, the door frame is installed on the wall 7, and the multi-lock structure door of the utility model, such as Figures 2 to 7 Shown, including:

[0042] A lock pin 1 is slidably mounted on a door leaf 9, with the end of the lock pin being able to slide out from the side of the door leaf, and a lock slot 81 for inserting the lock pin into the door frame 8;

[0043] A sliding rod 2 is slidably connected to the door leaf, and the rod body of the sliding rod has straight grooves 21 corresponding to the number of the locking pins. The length direction of the straight grooves is set at an acute angle to the sliding direction of the sliding rod. The other end of the locking pin is movably connected to the straight groove and can slide along the straight groove;

[0044] The handle 3 is connected to the slide bar and can drive the slide bar to slide.

[0045] During specific implementation, the slide rod is driven by the handle, and the locking pin is connected to the slide rod through an inclined straight groove. When the slide rod moves, the locking pin is driven to extend, and the locking pin is inserted into the locking groove. By locking the door leaf at the same time through multiple locking pins, the degree of closing of the door leaf can be ensured, thereby offsetting the airtightness problem caused by a larger door leaf or a door frame that is not very horizontal.

[0046] Similarly, in order to solve the problem more accurately, the above-mentioned locking pins are usually arranged on opposite sides of the long side of the door leaf.

[0047] It is well understood that the long sides of the door leaf are more likely to not close tightly, so from an economic point of view, it is more reasonable to set only the long sides. Of course, other settings such as single-side, three-side, and four-side settings are just simple changes based on the present invention and also fall within the scope of protection of the present invention.

[0048] On this basis, this embodiment also provides a second lock pin at the top and / or bottom of the door leaf. The function of the second lock pin is the same as that of the above-mentioned lock pin, but the driving method of the second lock pin is different.

[0049] The sliding rod is in the shape of a long rod and is arranged parallel to the long side of the door leaf. One end or both ends of the sliding rod are close to the short side of the door leaf, and the end is fixedly connected to a second lock pin 4. The second lock pin can be slidably connected relative to the door leaf along with the sliding rod. The second lock pin can slide out from the side of the door leaf, and the door frame 8 is correspondingly provided with a lock slot 81 for inserting the second lock pin.

[0050] That is, the second lock pin is driven by the slide bar. Since the slide bar is arranged parallel to the long side, its movement can directly insert it into the lock slot at the top of the door frame.

[0051] In this embodiment, the locking pin and the sliding rod are vertically arranged. This is because in this embodiment, other components are connected to both ends of the sliding rod, that is, the vertical arrangement of the sliding rod is a certain consideration in this embodiment. For the function of the locking pin, the sliding direction of the locking pin is perpendicular to the sliding rod, that is, perpendicular to the two sides of the door leaf, which is the most reasonable, at least it is easy to process. It is also acceptable to adopt a structure that extends out and inserts obliquely.

[0052] The best implementation method is to set the second lock pin at the top of the door leaf and set a sealing structure at the bottom of the door leaf. Specifically: a sealing plate 5 is connected to one end or both ends of the sliding rod, and the sealing plate is equal in length along the short side of the door leaf and is set parallel to the short side. The sealing plate can slide out of the side of the door leaf as the sliding rod slides.

[0053] In this embodiment, since the door leaf is a room door, the lower end of the door leaf is the ground. Generally, there is no door stop like a door frame on the ground. Therefore, the sealing plate is provided at the lower end of the door leaf to improve the sealing performance.

[0054] If the lock pin structure of the present invention is used in cabinet doors, boxes and the like, the four sides of the door leaf can all be provided with the same lock pin device, without the need for a sealing plate, and can be used in any combination as required.

[0055] Specifically, when the operating handle drives the slide rod to move, the sealing plate moves downward under the drive of the slide rod and fits with the floor at the lower end of the door leaf to seal the gap below the door leaf.

[0056] In order to ensure sealing performance, the sealing plate is made of rubber or is covered with rubber.

[0057] In a simple structure, the sealing plate is directly fixedly connected to the sliding rod, but since the sealing plate has a certain length, its rigidity is also related to the sealing performance when it is sealed after closing. In order to improve the overall stability and rigidity of the sealing plate, the sealing plate is also connected to the sliding rod through a connecting rod structure in this embodiment. Specifically, it also includes a connecting rod 51, the middle part of the connecting rod is hinged to the door leaf, one end of the connecting rod is movably connected to the sliding rod, and the other end of the connecting rod is movably connected to a pressure block 52, and the sealing plate is fixedly connected to the pressure block.

[0058] That is, the two pressing blocks are connected to the sealing plate at intervals, providing the sealing plate with two supporting points, so that the sealing plate has more stable rigidity, and then driven by the connecting rod.

[0059] In addition, in a specific implementation, there are many solutions for the sliding connection between the sliding rod and the locking pin and the door leaf. In this embodiment, a door leaf slotting method (or splicing groove) is adopted, and the door leaf has several grooves 91, and the sliding rod and the locking pin are slidably arranged in the grooves.

[0060] This structure can ensure the heavy sound insulation performance of the door leaf while conveniently forming the sliding groove required for sliding.

[0061] It should also be noted that in order to ensure the stability of the door leaf after the lock pin is inserted, the lock pin and the lock slot cannot be too loose. Here, the utility model provides two solutions:

[0062] 1. The side of the lock pin away from the closed door leaf is flush with one side notch of the lock slot, or protrudes from the notch.

[0063] 2. The door frame is provided with a door stop 82 for limiting the closing position of the door leaf, and a rubber strip is provided at the contact portion between the door stop and the door leaf.

[0064] Finally, regarding the driving method of the handle, the simplest structure is that the handle is directly fixedly connected to the slide rod, and the driving method of the handle is to move it along the sliding direction of the slide rod. This has the simplest structure and is more laborious to operate.

[0065] The handle in this embodiment is driven by a gear and rack structure. Specifically, a gear 31 is provided at one end of the handle, and a rack 32 is provided on the shaft of the slide rod. The slide rod is connected and driven by the gear and rack. With this structure, only one hole is required in the door leaf, and operating the handle by rotating it is more labor-saving than sliding it.

[0066] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
