When the mounting plate is subsequently installed with the door panel, it controls the opening and closing range of the double-leaf door.

Description

Technical Field

[0001] This utility model relates to the technical field of double-door limiting mechanisms, and in particular to a double-door limiting mechanism. Background Technology

[0002] A double door, also called a swing door, refers to a door with two separate door panels. It is typically designed as a double door when the doorway is wide, for ease of opening and aesthetic purposes. The upper and lower limit mechanisms of a double door control the degree of opening and closing, preventing excessive opening and collisions.

[0003] Most of the top-and-bottom door limiting mechanisms on the market currently use fixed-angle limiting designs, such as the common preset positions of 90° and 120°. While these structures provide basic opening and closing control functions, in real-world applications, the required door opening angle is often not fixed but needs to be flexibly adjusted based on the specific spatial layout, usage habits, or functional requirements. For example, in narrow passages, it may be necessary to limit the door opening to avoid collisions, while when ventilation or moving items is needed, it is desirable for the door to open to a wider angle. Traditional limiting mechanisms, due to their fixed angle and lack of adjustability, are difficult to adapt to diverse usage scenarios, thus limiting their practicality and user-friendliness in actual operation.

[0004] Based on this, this application proposes a top-and-bottom door limiting mechanism. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology, and to propose a top-and-bottom opening door limiting mechanism.

[0006] The technical problem to be solved by this utility model is to provide a limiting mechanism for vertically opening doors to solve the problem that the limiting angle is not adjustable in existing models.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A limiting mechanism for a vertically opening door includes: a column, two circular sleeves 1 fixedly mounted on the outer wall of the column, the two circular sleeves 1 being located at opposite ends of the column, and each of the two circular sleeves 1 having a mounting plate 1 fixedly connected to its outer wall, each of the two mounting plates 1 having two mounting holes 1; a circular sleeve 2 fixedly mounted at the center of the column, a sleeve sleeve movably mounted on the outer side of the circular sleeve 2, a mounting plate 2 fixedly mounted on the outer wall of the sleeve, the mounting plate 2 having two mounting holes 2; a limiting groove formed on the outer wall of the sleeve sleeve, a limiting block slidably connected to the inner cavity of the limiting groove, the limiting block being fixedly mounted on the outer wall of the circular sleeve 2; and an abutment block movably mounted in the inner cavity of the limiting groove.

[0009] Preferably, buffer pad one is embedded and fixedly installed on both sides of the outer wall of the limiting block, and buffer pad two is embedded and fixedly installed on the side of the outer wall of the contact block near the limiting block.

[0010] Preferably, the top and bottom of the abutment block are fixedly connected to movable blocks, the top and bottom of the inner wall of the limiting groove are provided with side grooves, the two movable blocks are respectively movably installed in the inner cavity of the corresponding side groove, and the two movable blocks are provided with positioning holes, the inner walls of the two side grooves are provided with multiple round holes, the top and bottom of the sleeve are provided with fixing pins, and one end of the fixing pin passes through the adjacent round hole and the positioning hole.

[0011] Preferably, arc-shaped strips are fixedly installed on the outer walls of both movable blocks, and arc-shaped grooves are opened on the inner walls of both side grooves. The two arc-shaped strips are slidably connected to the inner cavities of the corresponding arc-shaped grooves.

[0012] Preferably, a handle is fixedly installed on the outer wall of the fixing pin, and the handle is cylindrical.

[0013] Preferably, the outer wall of the fixing pin has multiple sets of anti-slip textures, and the outer wall of the fixing pin fits into the inner wall of the positioning hole.

[0014] Preferably, both the first mounting hole and the second mounting hole are elongated.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above solution, the limiting groove and the limiting block work together to limit the movement of the second mounting plate. When the second mounting plate moves to the point where the limiting block and the abutting block collide, the second mounting plate cannot move further, thus achieving the limiting operation. The position of the abutting block can be adjusted to control the movement range of the second mounting plate. When the second mounting plate is installed with the door panel, the purpose of controlling the opening and closing range of the double doors is achieved. Attached Figure Description

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

[0027] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The above-displacement door limiting mechanism, as shown in the embodiment of this utility model, includes: a column 1, two circular sleeves 2 fixedly mounted on the outer wall of the column 1, the two circular sleeves 2 being located at both ends of the column 1 respectively, and mounting plates 3 fixedly connected to the outer walls of the two circular sleeves 2, each of the two mounting plates 3 having two mounting holes 4, a circular sleeve 5 fixedly mounted at the center of the column 1, a sleeve 8 movably mounted on the outer side of the circular sleeve 5, a mounting plate 20 fixedly mounted on the outer wall of the sleeve 8, two mounting holes 21 on the mounting plate 20, a limiting groove 9 on the outer wall of the sleeve 8, a limiting block 6 slidably connected to the inner cavity of the limiting groove 9, the limiting block 6 being fixedly mounted on the outer wall of the circular sleeve 5, and an abutment block 11 movably mounted in the inner cavity of the limiting groove 9.

[0029] Specifically, firstly, bolts are passed through multiple mounting holes 4, and two mounting plates 3 are installed in the equipment. Then, bolts are passed through mounting holes 21, and mounting plate 20 is installed on the double doors. When the double doors are opened, the sleeve 8 will rotate synchronously. The sleeve 8 is limited by the cooperation of the limiting block 6 and the limiting groove 9, which limits the arc movement of the sleeve 8 and further limits the opening and closing of the double doors. During the rotation of the sleeve 8, the contact block 11 will move synchronously. After the contact block 11 moves to fit with the limiting block 6, the double doors move to the limit position.

[0030] Before the above operation, the position of the abutment block 11 can be adjusted according to the actual situation, thereby controlling the active area between the limit block 6 and the abutment block 11, so as to adjust the opening angle and opening range of the double door.

[0031] In this embodiment, as Figures 2-5 As shown; buffer pad 7 is embedded and fixedly installed on both sides of the outer wall of the limiting block 6, and buffer pad 12 is embedded and fixedly installed on the side of the outer wall of the contact block 11 near the limiting block 6.

[0032] Specifically, the combination of buffer pad 7 and buffer pad 12 can provide a buffering effect when the limiting block 6 contacts the abutting block 11 and when the limiting block 6 contacts the inner wall of the limiting groove 9, thus avoiding direct collision and preventing damage to the parts.

[0033] In this embodiment, as Figures 4-5 As shown; the top and bottom of the contact block 11 are fixedly connected to the movable block 14, the top and bottom of the inner wall of the limiting groove 9 are provided with side grooves 10, the two movable blocks 14 are respectively movably installed in the inner cavity of the corresponding side groove 10, and the two movable blocks 14 are provided with positioning holes 17, the inner walls of the two side grooves 10 are provided with multiple round holes 13, the top and bottom of the sleeve 8 are provided with fixing pins 15, one end of the fixing pin 15 passes through the adjacent round hole 13 and the positioning hole 17.

[0034] Specifically, when adjusting the position of the abutment block 11, remove the upper and lower fixing pins 15, then move the abutment block 11 so that the abutment block 11 drives the upper and lower movable blocks 14 to move synchronously. The two movable blocks 14 slide inside the two side grooves 10. After the abutment block 11 moves to the appropriate position, insert the two fixing pins 15 into the two positioning holes 17 respectively to realize the positioning operation of the two movable blocks 14, and further realize the positioning operation of the abutment block 11.

[0035] In this embodiment, as Figure 5 As shown; arc-shaped strips 18 are fixedly installed on the outer walls of the two movable blocks 14, and arc-shaped grooves 19 are opened on the inner walls of the two side grooves 10. The two arc-shaped strips 18 are slidably connected to the inner cavities of the corresponding arc-shaped grooves 19.

[0036] Specifically, when the two movable blocks 14 move, they will cause the two arc-shaped strips 18 to slide inside the two arc-shaped grooves 19, thereby limiting the movement of the movable blocks 14 and even the abutting block 11.

[0037] In this embodiment, as Figures 4-5 As shown; a handle 16 is fixedly installed on the outer wall of the fixing pin 15, and the handle 16 is cylindrical.

[0038] Specifically, the handle 16 facilitates the application of force to the fixing pin 15, thereby controlling the insertion and removal of the fixing pin 15.

[0039] In this embodiment, as Figure 5 As shown, multiple anti-slip textures 22 are provided on the outer wall of the fixing pin 15, and the outer wall of the fixing pin 15 fits against the inner wall of the positioning hole 17.

[0040] Specifically, the anti-slip texture 22 effectively increases the friction between the outer wall of the fixing pin 15 and the inner wall of the positioning hole 17, thereby improving the firmness of the fixing pin 15 insertion.

[0041] In this embodiment, as Figures 1-2 As shown, multiple mounting holes 1 (4) and multiple mounting holes 2 (21) are all arranged in an elongated shape.

[0042] Specifically, the above-mentioned configuration allows the bolt to be adjusted slightly within the mounting holes 4 and 21 as it passes through them.

[0043] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
