Description

Technical Field

[0001] This utility model relates to the field of security door technology, and in particular to a security door with an openable and closable threshold. Background Technology

[0002] A security door is a protective door at the entrance of a residence, designed to prevent theft and ensure safety. Using a security door enhances the protection of property and people inside the home. Security doors typically have a threshold at the bottom of the door panel. The threshold, a horizontal structure at the lower end of the door frame, serves as a building component, providing practical functions such as wind and dust protection. It also improves the seal between the door panel and the door frame, as well as between the door panel and the ground. Security doors with thresholds offer greater security.

[0003] Existing technologies often result in shoes being removed during door opening, obstructing the door and making it inconvenient to open and close. Furthermore, when moving outdoor shoes, shoes worn indoors can easily pick up dust from outside and bring it inside. The existing technology cannot effectively control the opening and closing of the door to facilitate entry and exit, or prevent dust and bacteria from being brought indoors. This leads to the problem of inconvenience in changing shoes when entering and leaving the house, hindering indoor cleanliness. Additionally, it fails to prevent toddlers from leaving the house and mosquitoes from entering during ventilation. Utility Model Content

[0004] In existing technical solutions, shoes removed during door opening can obstruct the door, making it inconvenient to open and close. When moving outdoor shoes, shoes worn indoors can easily pick up dust from outside and bring it inside. The existing solutions cannot achieve the desired effect of convenient door opening and closing and preventing dust and bacteria from being brought indoors through adjustable door thresholds. This leads to the problem of inconvenience in changing shoes before entering and leaving the house, which is detrimental to indoor cleanliness. Furthermore, the solutions fail to prevent toddlers from leaving the house and mosquitoes from entering during ventilation. Therefore, this invention provides a security door with an openable and closable door threshold.

[0005] The technical solution adopted in this utility model is: a security door for entering a house with an openable and closable threshold, comprising:

[0006] Mother door panel;

[0007] A movable door sill assembly is installed below the main door panel. The movable door sill assembly is used to block dust and shoes. The movable door sill assembly includes a first insert, a pin, a second insert, a movable door sill body, a bolt, and a hook. The first insert is fixedly installed below the side wall of the main door panel, the second insert is fixedly installed on the side wall of the movable door sill body, the pin is inserted into the first insert and the second insert, the bolt is rotatably connected to the movable door sill body, and the bolt is sleeved on the hook.

[0008] Furthermore, a sub-door panel is installed on one side of the mother door panel, and the hook is fixedly connected to the sub-door panel.

[0009] Furthermore, a positive L-groove is provided on the upper part of the movable threshold body, and an inverted L-groove is provided on the lower part of the mother door panel, with the inverted L-groove inserted into the positive L-groove.

[0010] Furthermore, a sealing strip is fixedly installed inside the positive L-groove, and the sealing strip is located between the positive L-groove and the inverted L-groove.

[0011] Furthermore, a handle is fixedly installed on the side wall of the main door panel.

[0012] Furthermore, hinges are fixedly installed on the side walls of the main door panel and the movable threshold body.

[0013] Furthermore, a low threshold is installed below the active threshold body.

[0014] The beneficial effects of this utility model are:

[0015] This utility model, through the design of a movable threshold component, allows shoes to be placed under the door and then directly entered the house. Whether the door is open from the inside or outside, shoes can be easily lifted to change in and out of the house, making shoe changing smooth and convenient, eliminating the hassle of bending over to move shoes, saving time, and effectively solving the problem of the inconvenience of changing shoes when entering and leaving the house. It also facilitates the movement of large furniture in and out. The adjustable opening and closing of the movable threshold body easily prevents dust and bacteria from entering the house. The movable threshold body clearly defines the boundary between the inside and outside of the house, preventing dust and bacteria from entering and improving the cleanliness of the house. At the same time, it can prevent toddlers from leaving the house during ventilation. Combined with a screen door, it can reduce the chance of mosquitoes entering the house, and the ventilation area is larger and more effective when the door is open. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0024] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a security door with an openable and closable threshold.

[0025] The specific technical solution includes a main door panel 1 and a movable threshold assembly 2;

[0026] like Figure 1-4As shown, the movable threshold assembly 2 is installed below the main door panel 1. The movable threshold assembly 2 is used to block dust and shoes. The movable threshold assembly 2 includes a first insert 201, a pin 202, a second insert 203, a movable threshold body 204, a bolt 205, and a hook 206. The first insert 201 supports the pin 202 to prevent it from falling. The second insert 203 covers the bottom of the pin 202. The pin 202 can fix the first insert 201 and the second insert 203 together. The threshold body 204 can cover the bottom of the mother door panel 1. The bolt 205 can be connected to the hook 206. After the bolt 205 is connected to the hook 206, it can drive the movable threshold body 204 to be fixed to the daughter door panel 3. The first insertion cylinder 201 is fixedly installed on the lower side wall of the mother door panel 1, and the second insertion cylinder 203 is fixedly installed on the side wall of the movable threshold body 204. The pin 202 is inserted into the first insertion cylinder 201 and the second insertion cylinder 203. The bolt 205 is rotatably connected to the movable threshold body 204 and is sleeved on the hook 206.

[0027] Both the main door panel 1 and the movable threshold body 204 are rotatably connected to the door frame via hinges 8. By pulling the pin 202 upward, the bottom of the pin 202 can be pulled out of the insert 203, thus releasing the fixation between the pin 202 and the insert 203. By rotating the main door panel 1, the main door panel 1 can drive the hinge 8 connected to it to rotate around the central axis of the hinge 8, allowing the main door panel 1 to be opened and closed independently. At this time, one end of the bolt 205 is hooked in the hook 206, and the fixation between the bolt 205 and the hook 206 can fix the movable threshold body 204 to the sub-door panel 3. At this time, the movable threshold body 204 can define the boundary between the inside and outside of the house. The movable threshold body 204 can be set to two heights. When the height of the movable threshold body 204 is 15 cm higher than the height of shoes outside the door, the top surface of the movable threshold body 204 is higher than the shoes. Shoes can be left outside the movable threshold body 204 without being pushed by the main door panel 1 when it opens or closes alone, preventing shoes from blocking the main door panel 1. This avoids the problem of shoes being moved separately, preventing dust from the soles of indoor shoes from being carried into the house. When the height of the movable threshold body 204 is 50 cm, it can effectively prevent toddlers learning to walk from entering the house. To prevent young children from climbing out of the house when the main door panel 1 is opened for ventilation, the latch 202 is inserted into the second socket 203. The latch 202 can fix the first socket 201 and the second socket 203 together. The fixation between the first socket 201, the latch 202, and the second socket 203 can fix the main door panel 1 and the movable threshold body 204 together. Rotating the bolt 205 horizontally can turn the bolt 205 out of the hook 206. At this time, the bolt 205 and the hook 206 are released from fixation, and the movable threshold body 204 is released from fixation to the child door panel 3. By rotating the main door panel 1, the first socket 201 can be moved. When rotated, the first insert 201 can drive the second insert 202 to rotate, the second insert 202 can drive the third insert 203 to rotate, and the second insert 203 can drive the movable threshold body 204 to rotate. The movable threshold body 204 can rotate synchronously with the main door panel 1, allowing the main door panel 1 and the movable threshold body 204 to be opened simultaneously. At this time, without the obstruction of the movable threshold body 204, large furniture can easily enter and exit the room from under the door frame. When the second insert 202 is pulled out from the first insert 201 and the second insert 203, the movable threshold body 204 is pulled, and the movable threshold body 204 pulls the hinge 8, which can remove the movable threshold body 204 from the door frame.

[0028] like Figure 1-4 As shown, a sub-door panel 3 is installed on one side of the mother door panel 1, and the hook 206 is fixedly connected to the sub-door panel 3.

[0029] The sub-door panel 3 is fixedly installed inside the door frame. The mother door panel 1, the movable threshold body 204, and the sub-door panel 3 can isolate the indoor and outdoor spaces and protect the indoor space.

[0030] like Figure 2 As shown, a positive L-groove 4 is provided above the movable door sill body 204, and an inverted L-groove 5 is provided below the mother door panel 1. The positive L-groove 4 and the inverted L-groove 5 are connected, which can improve the sealing between the mother door panel 1 and the movable door sill body 204. The inverted L-groove 5 is inserted into the positive L-groove 4.

[0031] like Figure 2 As shown, a sealing strip 6 is fixedly installed inside the positive L-groove 4. The sealing strip 6 can better improve the sealing between the main door panel 1 and the movable threshold body 204. The sealing strip 6 is located between the positive L-groove 4 and the inverted L-groove 5.

[0032] like Figure 1-2 As shown, a handle 7 is fixedly installed on the side wall of the mother door panel 1. By pulling the handle 7, the handle 7 can drive the mother door panel 1 to rotate, thus opening and closing the mother door panel 1.

[0033] like Figure 1 and Figure 3 As shown, hinges 8 are fixedly installed on the side walls of the main door panel 1 and the movable threshold body 204. The hinges 8 can drive the main door panel 1 and the movable threshold body 204 to connect with the door frame.

[0034] like Figure 1-2 As shown, a lower threshold 9 is installed below the movable threshold body 204, which can improve the sealing between the movable threshold body 204 and the ground.
