Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy doors and windows, in particular to a false stile blocking for a screen door. Background Art

[0002] Screen doors, which are equipped with screens, are mainly used to prevent mosquitoes. Screen doors are widely used in various places such as homes, restaurants, hotels, offices, hospitals, etc. The normal entrance and exit of the door opening only requires about 1 meter, but we need to consider moving objects in the house, especially in high-rise buildings. The first choice is to enter from the door opening, so the door needs to be made wider to prevent the problem of not being able to enter during transportation. The door is opened and closed many times, and the durability and operating comfort of the hardware must also be considered. Single-leaf doors generally cannot be made too wide, so biparting doors will be selected. Biparting doors can open one or both, so that the opening space is large, which is more convenient for entering and exiting and carrying items. One feature of biparting doors is that they need to have a false stile, because the door itself needs to be sealed, there must be an overlap relationship, so a false stile needs to be attached to the passive leaf. The false stile is a full-length profile, and there is no way to achieve the same appearance as the door leaf. In order to seal, we choose to install a plug in the gap between the false stile profile and the door frame.

[0003] Because the sealing performance of the false stile needs to be taken into consideration, the plugging is made of rubber material with a waterproof sealing effect. However, due to the structural characteristics of the false stile itself, multiple cavities are opened on the inside of the false stile. Therefore, the plugging must also be produced as the cavities are opened. The plugging also needs to specially set up sealing parts to seal the cavities, and the rubber material itself has a deformation function. As the number of cavities increases, the multiple sealing parts set up are prone to deform and shrink into the cavity, making the sealing part not fit the inner wall of the cavity, thereby reducing the sealing effect on the false stile and affecting the normal use of the false stile.

[0004] Therefore, it is particularly important to design a screen door false stile to solve the above-mentioned defects. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model designs a screen door false stile seal, which aims to solve the technical problem that the sealing part of the screen door false stile seal set in the false stile cavity in the prior art is easily deformed and contracted into the cavity, so that the sealing part does not fit the inner wall of the cavity, thereby reducing the sealing effect of the false stile and affecting the normal use of the false stile.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A false stile blocking for a screen door comprises a false stile body installed between two groups of screen door bodies and a blocking plate installed on the top of the false stile body, wherein the inner side of the false stile body is provided with a first cavity, a second cavity and a third cavity in sequence from front to back, a mounting portion is installed at the front end of the blocking plate, a first blocking frame, a second blocking frame and a third blocking frame are installed at the bottom of the blocking plate and inside the first cavity, the second cavity and the third cavity respectively, and a tightening mechanism is installed on the inner sides of the first blocking frame, the second blocking frame and the third blocking frame.

[0008] As a preferred solution of the utility model, the size of the blocking plate is the same as the size of the cross section of the false stile body, and the bottom of the blocking plate fits with the top of the false stile body.

[0009] As a preferred solution of the utility model, the mounting portion and the sealing plate are designed as an integrated structure, a hand buckle portion is fixedly provided at the front end of the mounting portion, and the mounting portion is designed as an L-shaped structure.

[0010] As a preferred solution of the utility model, the first sealing frame, the second sealing frame and the third sealing frame are all designed as an integrated structure with the sealing plate, the first sealing frame, the second sealing frame and the third sealing frame are all made of rubber material, the outer edges of the bottom ends of the first sealing frame, the second sealing frame and the third sealing frame are fixedly connected with a scraping protrusion, and the outer sides of the first sealing frame, the second sealing frame and the third sealing frame are all provided with two sets of rubber sealing rings.

[0011] As a preferred solution of the utility model, the tightening mechanism includes a fixed cylinder, a telescopic column, a spring and a top plate, the fixed cylinder is installed at the bottom end inside the first blocking frame, the second blocking frame and the third blocking frame, the two groups of telescopic columns are slidably connected to the left and right ends of the fixed cylinder, the spring is located inside the fixed cylinder and between the two groups of telescopic columns, the top plate is fixedly connected to one end of the telescopic column away from the fixed cylinder, and the top plates are all in contact with the inner walls of the first blocking frame, the second blocking frame and the third blocking frame.

[0012] As a preferred solution of the utility model, the outer side of the fixed cylinder is fixedly connected to the sealing plate through a mounting block, and mounting holes are provided at both the front and rear ends of the mounting block. The two groups of telescopic columns are located at one end inside the fixed cylinder and are fixedly connected to the limiting blocks on the left and right sides of the spring.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model adopts the matching design of the blocking plate, the installation part, the first blocking frame, the second blocking frame, the third blocking frame and the tight mechanism. When the blocking plate is installed, the first blocking frame, the second blocking frame and the third blocking frame are pressed into the first cavity, the second cavity and the third cavity by force through the blocking plate itself and the installation part. When the blocking plate is disassembled, the hand buckle part at the front end of the installation part is buckled up, so that it is convenient to buckle the blocking plate with force, and then it is convenient to disassemble the blocking plate. After the blocking plate is installed, the first blocking frame, the second blocking frame and the third blocking frame made of rubber are used to improve the sealing of the first cavity, the second cavity and the third cavity. The fixing tube is fixed through the installation hole on the installation block. The locking plate is installed at the bottom of the sealing plate and is located on the inner side of the first, second and third sealing frames. After the first, second and third sealing frames are pressed into the first, second and third cavities, the limit block is pushed under the action of the spring to make the telescopic column push toward the outside of the fixed tube, and then the inner side walls of the first, second and third sealing frames are supported by the top plate. When the first, second and third sealing frames are located on the inner side of the first, second and third cavities, the first, second and third sealing frames are more closely fitted to the first, second and third cavities, thereby greatly improving the sealing performance of the false stile sealing of the screen door.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0024] A false stile blocking for a screen door comprises a false stile body 2 installed between two groups of screen door bodies 1 and a blocking plate 3 installed on the top of the false stile body 2, the inner side of the false stile body 2 is provided with a first cavity 4, a second cavity 5 and a third cavity 6 in sequence from front to back, a mounting portion 7 is installed at the front end of the blocking plate 3, a first blocking frame 8, a second blocking frame 9 and a third blocking frame 10 are installed at the bottom of the blocking plate 3 and inside the first cavity 4, the second cavity 5 and the third cavity 6 respectively, and a tightening mechanism 11 is installed on the inner sides of the first blocking frame 8, the second blocking frame 9 and the third blocking frame 10.

[0025] Firstly, the size of the blocking plate 3 is the same as the size of the cross section of the false stile body 2, and the bottom of the blocking plate 3 fits with the top of the false stile body 2. After installation, the blocking plate 3 fits with the top of the false stile body 2. During installation, the gap between the blocking plate 3 and the top of the false stile body 2 is minimized to improve the sealing of the false stile of the screen door.

[0026] Furthermore, the mounting portion 7 and the blocking plate 3 are designed as an integrated structure, and a hand buckle portion 701 is fixedly provided at the front end of the mounting portion 7. The mounting portion 7 is designed as an L-shaped structure. When installing the blocking plate 3, the first blocking frame 8, the second blocking frame 9 and the third blocking frame 10 are pressed into the first cavity 4, the second cavity 5 and the third cavity 6 through the blocking plate 3 itself and the mounting portion 7. When disassembling the blocking plate 3, the hand buckle portion 701 at the front end of the mounting portion 7 is buckled up, thereby facilitating the application of force to buckle up the blocking plate 3, and then facilitating the disassembly of the blocking plate 3.

[0027] Then, the first blocking frame 8, the second blocking frame 9 and the third blocking frame 10 are all designed as an integrated structure with the blocking plate 3, and the first blocking frame 8, the second blocking frame 9 and the third blocking frame 10 are all made of rubber, and the outer edges of the bottom ends of the first blocking frame 8, the second blocking frame 9 and the third blocking frame 10 are fixedly connected with a scraping protrusion 801, and the outer sides of the first blocking frame 8, the second blocking frame 9 and the third blocking frame 10 are sleeved with two groups of rubber sealing rings 802. After the blocking plate 3 is installed, the first blocking frame 8, the second blocking frame 9 and the third blocking frame 10 made of rubber are used to improve the sealing of the first cavity 4, the second cavity 5 and the third cavity 6. At the same time, when the first blocking frame 8, the second blocking frame 9 and the third blocking frame 10 are pressed into the first cavity 4, the second cavity 5 and the third cavity 6, the scraping protrusion 801 and the rubber sealing ring 802 are squeezed into the first cavity 4, the second cavity 5 and the third cavity 6 together. Inside the second cavity 5 and the third cavity 6, the sealing performance between the first sealing frame 8, the second sealing frame 9 and the third sealing frame 10 and the first cavity 4, the second cavity 5 and the third cavity 6 is further improved by the rubber sealing ring 802, and then the sealing performance of the false stile body 2 is further improved. At the same time, when the sealing plate 3 is disassembled, as the sealing plate 3 is disassembled, the first sealing frame 8, the second sealing frame 9 and the third sealing frame 10 are slowly moved out from the inner side of the first cavity 4, the second cavity 5 and the third cavity 6, and then the dust entering the inner side walls of the first cavity 4, the second cavity 5 and the third cavity 6 are scraped out from the inside of the first cavity 4, the second cavity 5 and the third cavity 6 by the scraping protrusion 801 along the inner side walls of the first cavity 4, the second cavity 5 and the third cavity 6, thereby improving the cleanliness of the first cavity 4, the second cavity 5 and the third cavity 6 and further improving the applicability of the false stile sealing.

[0028] Secondly, in this embodiment, the specific structure of the compacting mechanism 11 is as follows:

[0029] The tightening mechanism 11 includes a fixed cylinder 1101, a telescopic column 1102, a spring 1103 and a top plate 1104. The fixed cylinder 1101 is installed at the bottom end of the first sealing frame 8, the second sealing frame 9 and the third sealing frame 10. The two groups of telescopic columns 1102 are slidably connected to the left and right ends of the fixed cylinder 1101. The spring 1103 is located inside the fixed cylinder 1101 and between the two groups of telescopic columns 1102. The top plate 1104 is fixedly connected to the end of the telescopic column 1102 away from the fixed cylinder 1101, and the top plate 1104 is in contact with the inner walls of the first sealing frame 8, the second sealing frame 9 and the third sealing frame 10.

[0030] Finally, the outer side of the fixed cylinder 1101 is fixedly connected to the blocking plate 3 through the mounting block 1105, and mounting holes are provided at both the front and rear ends of the mounting block 1105. Two sets of telescopic columns 1102 are located at one end of the fixed cylinder 1101 and are fixedly connected to the limit blocks 1106 on the left and right sides of the spring 1103. The fixed cylinder 1101 is installed at the bottom of the blocking plate 3 and is located on the inner sides of the first blocking frame 8, the second blocking frame 9 and the third blocking frame 10 through the mounting holes on the mounting block 1105. When the first blocking frame 8, the second blocking frame 9 and the third blocking frame 10 are pressed into the first cavity 4, the second cavity 5 and the third cavity 5, the fixed cylinder 1101 is fixedly connected to the blocking plate 3 through the mounting holes on the mounting block 1105. After entering the three cavities 6, the limit block 1106 is pushed under the action of the spring 1103, so that the telescopic column 1102 is pushed toward the outside of the fixed cylinder 1101, and then the inner walls of the first blocking frame 8, the second blocking frame 9 and the third blocking frame 10 are supported by the top plate 1104. When the first blocking frame 8, the second blocking frame 9 and the third blocking frame 10 are located on the inner side of the first cavity 4, the second cavity 5 and the third cavity 6, the first blocking frame 8, the second blocking frame 9 and the third blocking frame 10 are more closely fitted to the first cavity 4, the second cavity 5 and the third cavity 6, thereby further improving the sealing performance of the false center stile of the screen door.

[0031] In this embodiment, the implementation scenario is specifically as follows: when installing the blocking plate 3, the first blocking frame 8, the second blocking frame 9 and the third blocking frame 10 are pressed into the first cavity 4, the second cavity 5 and the third cavity 6 by the blocking plate 3 itself and the mounting portion 7. When disassembling the blocking plate 3, the hand buckle portion 701 at the front end of the mounting portion 7 is buckled up, so as to facilitate the application of force to buckle the blocking plate 3, and then facilitate the disassembly of the blocking plate 3. After the blocking plate 3 is installed, the first blocking frame 8, the second blocking frame 9 and the third blocking frame 10 made of rubber are used to improve the sealing of the first cavity 4, the second cavity 5 and the third cavity 6. The fixing tube 1101 is installed at the bottom of the blocking plate 3 and is located on the inner side of the first blocking frame 8, the second blocking frame 9 and the third blocking frame 10 through the mounting hole on the mounting block 1105. After the first blocking frame 8, the second blocking frame 9 and the third blocking frame 10 are pressed into the first cavity 4, the second cavity 5 and the third cavity 6, the limit block 1106 is pushed under the action of the spring 1103 to make the telescopic column 1102 push toward the outside of the fixed tube 1101, and then the inner wall of the first blocking frame 8, the second blocking frame 9 and the third blocking frame 10 is supported by the top plate 1104, and then when the first blocking frame 8, the second blocking frame 9 and the third blocking frame 10 are located on the inner side of the first cavity 4, the second cavity 5 and the third cavity 6, the first blocking frame 8, the second blocking frame 9 and the third blocking frame 10 are more fitted with the first cavity 4, the second cavity 5 and the third cavity 6, and the whole operation process is simple and convenient. Compared with the existing screen door false center jamb blocking, the utility model can improve the overall sealing and practicality of the screen door false center jamb blocking through design.
