Description

Technical Field

[0001] The utility model relates to the technical field of flat door accessories, and particularly to a mechanical stop device for a flat door to reach the closed position. Background Art

[0002] As the main passage for passengers to enter and exit, the safety performance of the flat door is directly related to the personal safety of passengers. However, the current flat door products on the market have significant limitations in design, especially in terms of the strength and stability of the door panel.

[0003] Specifically, the design of these door panels often only relies on the simple limit block between the upper edge of the door panel and the door head, and the shaft limit at the upper and lower parts of the door panel rotation shaft. This design may meet the basic requirements under normal use conditions, but in the face of sudden external impacts, especially when the impact point is in the middle or lower part of the door panel (i.e., the relatively weak area in terms of strength), the door panel is prone to large deformation. Such deformation may not only cause the door panel to rub against the running platform, resulting in equipment damage, but also may lead to serious safety accidents. Therefore, we make improvements and propose a mechanical stop device for a flat door to reach the closed position. Summary of the Invention

[0004] The purpose of the utility model is to address the problem that when the impact point is in the middle or lower part of the door panel (i.e., the relatively weak area in terms of strength), the door panel is prone to large deformation.

[0005] In order to achieve the above invention purpose, the utility model provides a mechanical stop device for a flat door to reach the closed position to improve the above problems.

[0006] Specifically, this application is as follows:

The second stop member can be detachably connected to the first stop member, and when the second stop member is connected to the first stop member, it is used to block the door panel frame.

[0008] As a preferred technical solution of this application, the first stop member is a blocking seat, and the blocking seat is arranged on the floor sill.

[0009] As a preferred technical solution of this application, a first installation groove for installing the blocking seat is opened on the floor sill, and several first installation bolts are connected between the floor sill and the blocking seat.

[0010] As a preferred technical solution of the present application, the top of the blocking seat has a limit groove, and a slope is provided on the side wall at the opening of the limit groove.

[0011] As a preferred technical solution of the present application, the second blocking member includes a first installation groove provided at the bottom of the door panel frame, a limit bracket is provided in the first installation groove, and the bottom end of the limit bracket extends out of the first installation groove and is inserted into the limit groove.

[0012] As a preferred technical solution of the present application, the limit bracket is provided in a hook shape, the bottom end of the limit bracket is a hook-shaped end, and a hole is provided on the blocking seat for the hook-shaped end of the limit bracket to pass through.

[0013] As a preferred technical solution of the present application, the limit bracket is provided in an L shape, and the bottom end of the limit bracket is vertically arranged.

[0014] As a preferred technical solution of the present application, a second installation groove is further provided in the door panel frame, and a connecting member is provided between the second installation groove and the limit bracket.

[0015] As a preferred technical solution of the present application, the connecting member includes a connecting seat inserted into the second installation groove, and a plurality of second fixing bolts are connected between the connecting seat and the limit bracket.

[0016] As a preferred technical solution of the present application, a gap is left between one side of the bottom of the limit bracket and the limit groove.

[0018] As a preferred technical solution of the present application, a door panel glass is installed in the door panel frame.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] In the solution of the present application:

[0021] In order to solve the problem that in the prior art, when the impact point is located in the middle or below the door panel (i.e., the area with relatively weak strength), the door panel is prone to large deformation. In the present application, a blocking part is provided between the door panel frame and the sill, the blocking part is composed of a first blocking member and a second blocking member, and the second blocking member is connected to the first blocking member for blocking the door panel frame, effectively limiting the deformation range of the door panel frame when subjected to external force impact.

[0032] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] As described in the background art, there are significant limitations in the design of current market side-hung door products, especially in terms of the strength and stability of the door panels. Specifically, the design of these product door panels often relies only on the simple limit block between the upper edge of the door panel and the door head, as well as the shaft limit at the upper and lower parts of the door panel rotation axis. This design may meet the basic requirements under normal use conditions, but when faced with sudden external force impacts, especially when the impact point is in the middle or lower part of the door panel (i.e., the relatively weak strength area), the door panel is prone to large deformations. Such deformations may not only cause scratches between the door panel and the running platform, resulting in equipment damage, but may also lead to serious safety accidents.

[0034] To solve this technical problem, the present utility model provides a mechanical stop device for a side-hung door to reach the closed position.

[0035] Specifically, please refer to Figures 1-6 , the mechanical stop device for a side-hung door to reach the closed position specifically includes:

[0036] A sill 103 and a rotatable and openable door panel frame 101. A stop portion is provided between the sill 103 and the door panel frame 101. The stop portion is located on the side of the door panel frame 101 away from the rotation point. The stop portion includes a first stop member provided on the sill 103 and a second stop member provided on the door panel frame 101. The second stop member and the first stop member can be detachably connected together, and the second stop member and the first stop member are connected together for blocking the door panel frame 101.

[0037] For the mechanical stop device for a side-hung door to reach the closed position provided by the present utility model, in this application, a stop portion is provided between the door panel frame 101 and the sill 103. The stop portion is composed of a first stop member and a second stop member. The second stop member and the first stop member are connected together for blocking the door panel frame 101, effectively limiting the deformation range of the door panel frame 101 when subjected to external force impacts. It not only meets the 300N force test standard required by regulations, but also enhances the resistance, greatly reducing the accident risk caused by door panel deformation and ensuring the personal safety of passengers and operators.

[0038] To enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0039] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0040] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0041] Example 1, please refer to Figures 1-6 , a mechanical stop device for a French door to close in place, including a sill 103 and a door panel frame 101 that can rotate and open / close. A stop portion is provided between the sill 103 and the door panel frame 101. The stop portion is located on the side of the door panel frame 101 away from the rotation point. The stop portion includes a first stop member provided on the sill 103 and a second stop member provided on the door panel frame 101. The second stop member and the first stop member can be detachably connected together. The second stop member and the first stop member are connected together for blocking the door panel frame 101. In this application, by providing a stop portion between the door panel frame 101 and the sill 103, the stop portion is composed of a first stop member and a second stop member, and the second stop member and the first stop member are connected together for blocking the door panel frame 101, effectively limiting the deformation range of the door panel frame 101 when subjected to external force impact. It not only meets the 300N force test standard required by regulations but also enhances the resistance, greatly reducing the accident risk caused by door panel deformation and ensuring the personal safety of passengers and operators.

[0042] Furthermore, as Figures 1-6 shown, the first stop member is a blocking seat 2, and the blocking seat 2 is provided on the sill 103.

[0043] Furthermore, as Figure 2 shown, a first installation groove for installing the blocking seat 2 is provided on the sill 103. A number of first installation bolts 201 are connected between the sill 103 and the blocking seat 2, and the first installation bolts 201 realize the installation of the blocking seat 2, which is convenient for disassembly and assembly.

[0044] Furthermore, as Figure 2 shown, the top of the blocking seat 2 has a limit groove, and a slope is provided on the side wall at the opening of the limit groove. The setting of the slope facilitates the insertion of the second stop member into the limit groove.

[0045] Furthermore, as Figures 4-6 shown, the second stop member includes a first installation groove 3 provided at the bottom of the door panel frame 101. A limit bracket 301 is provided in the first installation groove 3. The bottom end of the limit bracket 301 extends out of the first installation groove 3 and is inserted into the limit groove. The mutual cooperation between the limit bracket 301 and the limit groove can realize the blocking of the door panel frame 101 and improve the stability of the door panel frame 101.

[0046] Example 2, further optimize the mechanical stop device for a French door to close in place provided in Example 1. Specifically, as Figure 5 shown, the limit bracket 301 is provided in a hook shape, the bottom end of the limit bracket 301 is a hook end, and a hole for the hook end of the limit bracket 301 to pass through is provided on the blocking seat 2;

[0047] When the automatic double - door closes in place, the limit bracket 301 can be hooked into the limit slot. When the door panel glass 102 is subjected to an external force, the hole through which the hooked end of the limit bracket 301 passes will pass through the hole and move towards the cavity of the sill 103. When the moving amount offsets the gap between the limit bracket 301 and the sill 103, the limit bracket 301 no longer generates displacement but is restricted by the sill 103. If the external force applied to the door panel glass 102 continues to be applied and increased, it will cause the door panel glass 102 to deform. When the force applied to the door panel glass 102 is equal to 300 N and this force is maintained, the door panel glass 102 no longer deforms. When the strength of the door panel glass 102 is sufficient, at this time, the elastic deformation of the door panel glass 102 is not greater than 15 mm. When the 300 - N force applied to the door panel glass 102 is withdrawn, the elastic deformation of the door panel glass 102 is restored without permanent deformation. When the door panel glass 102 is impacted by a soft or hard pendulum hammer, the limit bracket 301 hooks the sill 103 to prevent the door panel glass 102 from undergoing large deformations, thereby passing the pendulum - hammer test.

[0048] Example 3 further optimizes the mechanical stop device for the flat - open door closing in place provided in Example 1. Specifically, as Figure 6 shown, the limit bracket 301 is arranged in an L - shape, and the bottom end of the limit bracket 301 is vertically arranged. When closing the door, after the bottom end of the limit bracket 301 is inserted into the limit slot, it can block the door panel frame 101.

[0049] Example 4 further optimizes the mechanical stop device for the flat - open door closing in place provided in the above - mentioned examples. Specifically, as Figure 5 and Figure 6 shown, a second installation groove 302 is further opened in the door panel frame 101. A connecting piece is arranged between the second installation groove 302 and the limit bracket 301, and the connecting piece is used to connect the door panel frame 101 and the limit bracket 301.

[0050] Furthermore, as Figure 5 and Figure 6 shown, the connecting piece includes a connecting seat 303 inserted into the second installation groove 302. A number of second fixing bolts 304 are connected between the connecting seat 303 and the limit bracket 301. Through the mutual cooperation of the second fixing bolts 304 and the second installation groove 302, the limit bracket 301 can be installed and fixed.

[0051] Furthermore, as Figure 5 and Figure 6 shown, there is a gap between one side of the bottom of the limit bracket 301 and the limit slot, and the gap is the Figure 5 and Figure 6 marking at A in

[0052] Example 5 further optimizes the mechanical stopping device for the flat door to be in place when closed provided in the above embodiments. Specifically, as Figure 1 shown, the number of door panel frames 101 is two. A support frame 1 is connected between the two door panel frames 101, and both the two door panel frames 101 and the support frame 1 are rotatably connected. The floor sill 103 is installed at the bottom of the door panel frame 101, and the support frame 1 is used for the support of the support frame 1.

[0053] Further, as Figure 1 shown, a door panel glass 102 is installed inside the door panel frame 101.

[0054] The structure of this application is simple, the installation is convenient and fast, and the overall setting makes less changes to the existing door panel frame 101 and floor sill 103, that is, there are fewer changed components and the cost is low.
