Description

Technical Field

[0001] The utility model belongs to the technical field of floor spring doors, and particularly relates to a new type of steel floor spring door. Background Art

[0002] Floor spring doors are commonly used in places such as stores and office partitions. They have the advantages of good permeability, beautiful appearance, and the ability to open both inwards and outwards, and are very common.

[0003] Due to the influence of the fan-shaped opening method and the profile structure of the existing floor spring doors, there are certain drawbacks in airtightness. There will be obvious gaps between the door leaf and the door frame, and there will also be obvious convection phenomena when closing.

[0004] Currently, flexible sealing strips or wool strips are mostly installed at the gap positions, which can achieve a certain sealing effect. However, it is still difficult to ensure strict airtightness in the case of large pressure differences such as strong winds, and it is inconvenient to use. Moreover, this sealing method is mostly a single sealing measure, and the sealing effect is also limited. With the extension of the use time and the aging and deformation of related accessories, once the door leaf does not return completely, the sealing strip or wool strip will be misaligned to generate gaps, and the sealing effect will be lost. Summary of the Utility Model

[0005] In order to solve the technical problem of incomplete sealing of the existing floor spring doors, the utility model provides a new type of steel floor spring door to improve the sealing effect.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A new type of steel floor spring door includes a door frame embedded in a door opening, and at least one door leaf hinged to the door frame;

[0008] At least around the periphery of the door leaf away from the hinged direction, there is a limiting part, and on the opposite direction of the limiting part, there is a first sealing strip placed on the other door leaf or the door frame, and the first sealing strip and the limiting part are mutually adapted and docked.

[0009] Furthermore, a second sealing strip is provided on the door leaf at least on one side direction of the limiting part.

[0010] Furthermore, limiting parts are provided on both vertical peripheries and the top periphery of the door leaf.

[0011] Furthermore, the first sealing strip is placed in a card slot on the other door leaf or the door frame.

[0012] Furthermore, the limiting part is located at the central axis of the periphery of the door leaf.

[0013] Furthermore, the limiting part is a limiting groove adapted to the first sealing strip.

[0014] Furthermore, a rubber strip groove for accommodating the second sealing strip is provided on the door leaf.

[0015] Furthermore, both the first sealing strip and the second sealing strip are fireproof rubber strips.

[0016] Due to the adoption of the above technical solutions, the present utility model has the following beneficial effects:

[0017] The traditional floor spring door has a single sealing structure, that is, it uses a sealing rubber strip or a wool strip for sealing. Once it is damaged after long-term use, it loses the sealing effect. However, the present utility model uses a mutually adapted docking method for sealing, and also has two additional second sealing strips, which can form a triple sealing structure and has a better sealing effect.

[0018] In addition, affected by the docking structure, when the door leaf is closed with the door frame, or when two door leaves are closed, it can achieve more accurate positioning, ensure the accuracy of the door leaf closing, prevent the situation that the door leaf cannot be closed tightly after long-term use, and has a longer service life.

[0027] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the following will be described with reference to the appended Figures 1 to 4Embodiments are provided to further elaborate on the present utility model in detail. However, it should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0028] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0029] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected", "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] Referring to the attached Figure 1 to the attached Figure 4 , this embodiment provides a new type of steel floor spring door. In this embodiment, taking a single door leaf as an example for illustration, it can be inward-opening, outward-opening, or double-opening, and has a more excellent sealing effect.

[0031] It includes a door frame 100 embedded in the door opening, and at least one door leaf 200 hinged to the door frame 100. The hinged manner is preferably the hinged manner of a floor spring. At least a limiting portion 202 is provided on the periphery of the door leaf 200 away from the hinged direction. Generally speaking, a limiting portion 202 is provided on a vertical periphery of the door leaf 200 close to the opening direction, and its specific structure is a groove structure. The reason for adopting the groove structure is that the door leaf is opened frequently, and it is very easy to be accidentally touched or scratched against this vertical periphery after being opened. If a rubber strip is provided at this position, it is very easy to be rubbed off and separated. By adopting the groove structure, such a situation will not occur.

[0032] In addition, a first sealing strip 103 is provided on the vertical frame edge 101 of the door frame 100 in the opposite direction of the limiting portion 202, and the first sealing strip 103 and the limiting portion 202 are adapted and docked with each other. Specifically, when the door leaf 200 is closed, the first sealing strip 103 can be docked with the limiting portion 202. This structure not only facilitates sealing but also plays a role in limiting the door leaf. Since the first sealing strip 103 is restricted in the limiting portion 202 and is difficult to displace, the door leaf cannot easily shift and form a gap, and the overall service life is longer. The limiting portion 202 is preferably located at the central axis of the periphery of the door leaf 200, that is, at the axis of symmetry of the periphery of the door leaf 200. Of course, the volume of the first sealing strip 103 should not be excessively larger than that of the limiting portion 202, otherwise the door leaf will be easily resisted by it and difficult to close completely.

[0033] In this embodiment, a second sealing strip 204 is provided on the door leaf 200 at least on one side of the limiting portion 202. It can be placed in the rubber strip groove 203 on the door leaf 200 for easy disassembly and fixing, thereby forming two sealing structures. In practice, the second sealing strip 204 is mostly provided on both sides, so that a three-sealing structure can be formed. Compared with the traditional sealing method, the sealing effect is better, and it also has a limiting effect on the door leaf 200 to prevent it from not closing completely.

[0034] Moreover, in practice, the limiting portions 202 are provided on both vertical peripheries and the top periphery of the door leaf 200, and the bottom edge is realized through other sealing structures. For example, sealing wool strips or rubber strips.

[0035] In order to achieve a better limiting and fixing effect on the first sealing strip 103, the first sealing strip 103 is placed in the card slot 102 on the other door leaf 200 or the door frame 100, so that it is not easy to fall off and be damaged.

[0036] In this embodiment, both the first sealing strip 103 and the second sealing strip 204 are fireproof rubber strips, which can expand and block gaps in case of fire, and the safety is better. Of course, the glass 3 on the door leaf 200 is preferably made of fireproof glass. The profile is also made of steel material, which has a better fire resistance effect.

[0037] In another embodiment, taking two double-leaf doors as an example, it can be inward-opening, outward-opening or double-directionally opening, and it also has a more excellent sealing effect.

[0038] The same parts of this embodiment and the above embodiment will not be described in detail.

[0039] In this embodiment, a limiting portion 202 is provided on the periphery of one door leaf 200 away from the hinge direction, and then a first sealing strip 103 needs to be provided on the periphery of the other door leaf 200 away from the direction, so as to form a good docking and sealing effect.

[0040] Of course, the above structure can also be provided for the two vertical peripheries 201 and the top edge of the door leaf, and a conventional sealing method can also be adopted for the bottom edge.

[0041] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0042] The traditional floor spring door has a single sealing structure, that is, it uses a sealing strip or a wool strip for sealing. Once it is damaged after long-term use, the sealing effect is lost. However, the utility model adopts a docking method that matches each other for sealing, and is also provided with two additional sealing strips II, which can achieve a triple sealing structure and has a better sealing effect.

[0043] In addition, affected by the docking structure, when the door leaf and the door frame are closed, or when two door leaves are closed, the door leaf can be more accurately positioned, ensuring the accuracy of the door leaf closing and preventing the situation that the door leaf cannot be closed tightly after long-term use, thus having a longer service life.

[0044] Although the utility model has been described above with reference to the embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the utility model. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed by the utility model can be combined with each other in any way. The exhaustive description of these combinations is not given in this specification only for the consideration of saving space and resources. Therefore, the utility model is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
