Description

Technical Field

[0001] The utility model belongs to the technical field of fireproof doors, in particular to a fireproof door which is easy to install. Background Art

[0002] As an important safety facility in a building, fire doors can effectively isolate fire and prevent it from spreading when a fire occurs, providing important protection for people's lives and property safety. The materials used in the main structure of fire doors include metal materials such as steel and stainless steel. These metal materials have good fire resistance and structural strength and can remain stable for a long time in a fire. Some fireproof materials, such as rock wool and glass fiber, are filled inside the fire door to enhance its fire resistance and thermal insulation performance. Therefore, the overall weight of a fire door is usually much greater than that of a general door body.

[0003] However, there are some technical difficulties in the installation process of fire doors, mainly concentrated on the connection between the door frame and the door leaf. The traditional installation method requires the door leaf and door frame to be installed separately and then connected. After the door frame is connected to the building frame, the door leaf and door frame are aligned to connect the hinges. Due to the heavy weight of the fire door and the complex door frame structure, this installation method requires at least two workers to operate together, resulting in greater construction difficulty. The door frame shakes greatly during the installation of the hinge, which is prone to problems such as improper installation and looseness between the door leaf and the door frame. Utility Model Content

[0004] The purpose of the utility model is to provide a fireproof door which is easy to install, so as to solve the problems raised in the above-mentioned prior art.

[0005] Provided is a fire door that is easy to install, comprising:

[0006] The door body comprises a door frame and a door leaf, and a mounting groove is provided on one side of the door leaf;

[0007] A hinge component, wherein at least one hinge of the hinge component extends outward from the plate structure to form an insertion strip, and the insertion strip can be embedded in the interior of the mounting groove. The hinge of the hinge component with the insertion strip is fixedly connected to the door leaf, and the other hinge of the hinge component is fixedly connected to the door frame.

[0008] The supporting structure according to the embodiment of the utility model has at least the following technical effects:

[0009] When assembling the door leaf and door frame, you can first insert the insert into the installation groove to temporarily fix the door leaf and door frame, reducing the difficulty of manually stabilizing the door leaf. The cooperation between the insert and the installation groove plays a positioning role in the door leaf and door frame. There is no need to repeatedly adjust the position of the door leaf relative to the door frame. The hinge part can be directly fixed to the door leaf and door frame.

[0010] Furthermore, the two hinges of the hinge member extend outwardly from the plate structure to form an insertion strip, and a mounting groove is provided on one side of the door frame, and the insertion strip can be embedded in the mounting groove on the door sill. The door frame and the door leaf are both provided with mounting grooves to cooperate with the hinge member to enhance the positioning effect.

[0011] Furthermore, the notch of the installation groove is located on the adjacent side of the opposite surface of the door leaf and the door frame. This structure allows the hinge of the hinge member located on the door leaf side to extend out of the opposite surface of the door leaf and the door frame, thereby allowing the hinge part to avoid the opposite surface of the door leaf and the door frame and be located outside the opposite surface, thereby avoiding interference between the hinge of the hinge member and the door leaf or the door frame.

[0012] Furthermore, the installation slot on the door frame is located at the adjacent side of the opposite surface of the door frame and the door leaf. When the door frame is also provided with the installation slot, this structure enables the hinge of the hinge member located on the door frame side to extend out of the opposite surface of the door leaf and the door frame, thereby enabling the hinge part to avoid the opposite surface of the door leaf and the door frame and be located outside the opposite surface, thereby avoiding the interference between the hinge of the hinge member and the door leaf or the door frame.

[0013] Furthermore, the door leaf is located at the adjacent side of the door leaf and the door frame and extends outward to form a convex block, and the notch of the installation groove is located on the side of the convex block opposite to the door frame. This structure can avoid the hinge of the hinge member located on the door leaf side and the insertion strip from forming a certain angle to cooperate with the installation groove, and can simplify the structure of the hinge member, and the hinge of the hinge member can be extended.

[0014] Furthermore, the door frame is located at the adjacent side of the door frame and the door leaf opposite to each other and extends outward to form a protrusion, and the notch of the installation groove is located on the side of the protrusion opposite to the door leaf. When the door frame is also provided with an installation groove, this structure can avoid the hinge of the hinge member located on the door frame side and the insertion strip from forming a certain angle to cooperate with the installation groove, and can simplify the structure of the hinge member, and the hinge of the hinge member can be extended.

[0015] Furthermore, a side of the door leaf adjacent to the notch of the installation groove and on the side wall opposite to the inner cavity of the installation groove is provided with a plurality of first bolt holes, and a second bolt hole corresponding to the plurality of first bolt holes is provided on the inserting strip. When the inserting strip is inserted into the installation groove, the bolts are passed through the first bolt hole and the second bolt hole, which can strengthen the fixing effect of the inserting strip and the installation groove, improve the connection strength between the door leaf and the door frame, and prevent the gap between the inserting strip and the installation groove from causing excessive local stress.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] When the fireproof door provided by the utility model is installed, after the door frame and the wall are fixed, the insert strips on the hinge parts can cooperate with the installation grooves to realize pre-fixation of the door leaf and the door frame, and realize positioning at the same time, thereby reducing the problems of shaking, instability and inaccurate positioning caused by manual support of the door leaf and reducing the difficulty of construction.

For example, detailed descriptions of well-known matters and repeated descriptions of substantially the same structures may be omitted. This is to avoid the following description from becoming unnecessarily lengthy and to facilitate understanding by those skilled in the art. In addition, the drawings and the following description are provided to enable those skilled in the art to fully understand the present application and are not intended to limit the subject matter described in the claims.

[0027] See also Figure 1 and Figure 2 As shown, in an embodiment of the utility model, a fireproof door that is easy to install includes a door body 1 and a hinge member 2. The door body 1 includes a door frame 11 and a door leaf 12. A mounting groove 3 is opened on one side of the door leaf 12. The hinge member 2 has at least one hinge extending outward from the plate structure to form an insertion strip 21, and the insertion strip 21 can be embedded in the interior of the mounting groove 3. The hinge of the hinge member 2 with the insertion strip 21 is fixedly connected to the door leaf 12, and the other hinge of the hinge member 2 is fixedly connected to the door frame 11.

[0028] In one embodiment, the insertion strip 21 is located on the hinge of the hinge member 2 near the door leaf 12. When the door leaf 12 is assembled with the door frame 11, the hinges of the hinge members 2 at the end away from the insertion strip 21 are connected and fixed to the door frame 11 by bolts, and then the mounting grooves 3 on the door leaf 12 are aligned and matched with the corresponding insertion strips 21. The door leaf 12 and the door frame 11 can be temporarily fixed by the restriction of the insertion strip 21 and the mounting groove 3 to prevent the door leaf 12 from deviating. At this time, the hinge of the hinge member 2 is connected and fixed to the door leaf 12 by bolts to achieve temporary fixation and positioning of the door leaf 12.

[0029] As a further example of the main implementation scheme, the two hinges of the hinge member 2 are respectively engaged with the installation grooves 3 of the door leaf 12 and the door frame 11 through the insertion strips 21, that is, the two hinges of the hinge member 2 extend outward from the plate structure to form the insertion strips 21, and the installation groove 3 is also opened on one side of the door frame 11. When installing the door leaf 12, first insert one of the insertion strips 21 on the hinge members 2 into the installation groove 3 on the door frame 11 to fix the hinge on the door frame 11 side, and then match the installation groove 3 on the door leaf 12 with the corresponding insertion strips 21 to fix the hinge on the door leaf 12 side to the door leaf 12. This fixing method can reduce the positioning adjustment between the hinge member 2 and the door frame 11, and the operation is more convenient.

[0030] As a further example of the main implementation, see Figure 1 and Figure 2 As shown, the notch of the installation groove 3 is located on the adjacent side of the opposite surface of the door leaf 12 and the door frame 11, and the cavity of the installation groove 3 extends along the width direction of the door leaf 12. In order to adapt to the extension direction of the installation groove 3, the insertion strip 21 forms an angle of 90° with the hinge of the hinge member 2. This structure allows the hinge of the hinge member 2 located on the side of the door leaf 12 to extend out of the opposite surface of the door leaf 12 and the door frame 11, and then the hinge part of the hinge member 2 can avoid the opposite surface of the door leaf 12 and the door frame 11 and be located outside the opposite surface, avoiding the interference between the hinge of the hinge member 2 and the door leaf 12 or the door frame 11.

[0031] Furthermore, the notch of the installation groove 3 on the door frame 11 is located on the adjacent side of the opposite surface of the door frame 11 and the door leaf 12. This structure is an improvement on the basis that the two hinges of the hinge member 2 are respectively engaged with the installation grooves 3 of the door leaf 12 and the door frame 11 through the insertion strip 21. The hinge of the hinge member 2 located on the door frame 11 side can extend to the outside of the opposite surface of the door leaf 12 and the door frame 11, and then the hinge part can avoid the opposite surface of the door leaf 12 and the door frame 11 and be located outside the opposite surface, avoiding the interference between the hinge of the hinge member 2 and the door leaf 12 or the door frame 11.

[0032] As a further example of the main implementation, see Figure 1 and Figure 3As shown, the door leaf 12 is located at the adjacent side of the opposite surface of the door leaf 12 and the door frame 11 and extends outward to form a protrusion 121. The protrusion 121 is integrally formed with the plate on the door leaf 12 to ensure the strength of the connection area. The notch of the mounting groove 3 is located on the side of the protrusion 121 relative to the door frame 11. The function of the protrusion 121 is to move the position of the mounting groove 3 outward relative to the surface of the door leaf 12. The insertion strip 21 is formed by the hinge of the hinge member 2 continuing to extend outward along the length direction, and the angle between the hinge and the hinge is 180°. When the insertion strip 21 is assembled with the mounting groove 3, the hinge of the hinge member 2 can be located outside the opposite surface of the door leaf 12 and the door frame 11, avoiding the interference between the hinge of the hinge member 2 and the door leaf 12 or the door frame 11. At the same time, the structure of this hinge member 2 is relatively simple and the processing difficulty is relatively low.

[0033] Furthermore, the door frame 11 is located on the adjacent side of the opposite surface of the door frame 11 and the door leaf 12 and extends outward to form a protrusion 121. The notch of the installation groove 3 is located on the side of the protrusion 121 relative to the door leaf 12. The protrusion 121 is integrally formed with the plate on the door frame 11 to ensure the strength of the connection area. This structure is an improvement on the basis that the two hinges of the hinge member 2 are respectively engaged with the door leaf 12 and the installation groove 3 of the door frame 11 through the insertion strip 21. This structure can avoid the need for the hinge of the hinge member 2 on the side of the door frame 11 to form a certain angle with the insertion strip 21 to cooperate with the installation groove 3, and can simplify the structure of the hinge member 2 by extending the hinge of the hinge member 2.

[0034] See also Figure 1 and Figure 4 As shown, a side of the door leaf 12 adjacent to the notch of the installation groove 3 and on the side wall opposite to the inner cavity of the installation groove 3 is provided with a plurality of first bolt holes 122, and a second bolt hole 211 corresponding to the plurality of first bolt holes 122 is provided on the insert strip 21. By reserving the first bolt hole 122 and the second bolt hole 211, bolts can be used to reinforce the insert strip 21 after it is matched with the installation groove 3, and the connection strength is further enhanced on the basis of the bolt reinforcement between the hinge of the hinge member 2 and the door leaf 12. At the same time, the gap between the insert strip 21 and the installation groove 3 can be eliminated to avoid excessive local stress and local deformation. In addition, when the insert strip 21 enters the installation groove 3, if the first bolt hole 122 is aligned with the second bolt hole 211, it means that the door leaf 12 and the door frame 11 have been positioned, reducing the difficulty of positioning.

[0035] It should be noted that the present application is not limited to the above-mentioned embodiments. The above-mentioned embodiments are only examples, and the embodiments having the same structure as the technical idea and exerting the same effect within the scope of the technical solution of the present application are all included in the technical scope of the present application. In addition, without departing from the scope of the main purpose of the present application, various modifications that can be thought of by those skilled in the art to the embodiments and other methods of combining some of the constituent elements in the embodiments are also included in the scope of the present application.
