Description
Technical Field
[0001] This utility model belongs to the field of folding door technology, and specifically relates to a folding door with good stability. Background Technology
[0002] A folding door is a type of door that can be folded up, also known as a sliding door or push-pull door. It is usually composed of multiple interconnected panels or glass, which can be easily folded up or unfolded by pushing and pulling. Folding doors are commonly found in indoor or outdoor doors and windows. They can be used to divide space or as a transition door between indoor and outdoor spaces. They do not take up extra space and are characterized by their beauty, flexibility, and space saving. They are widely used in residential, commercial, and office spaces. They can effectively provide insulation, dust prevention, noise reduction, sound insulation, and privacy. Therefore, it is necessary to design a folding door with good stability.
[0003] Traditional sliding doors mostly operate by using rollers and tracks. However, over time, the rollers may wear down and derail. Additionally, improper installation by operators that fails to align the rollers with the tracks can also cause derailment, thus affecting the stability of the folding door during later use. Utility Model Content
[0004] The purpose of this utility model is to provide a folding door with a simple structure, reasonable design, and good stability in order to solve the above problems.
[0005] This utility model achieves the above objectives through the following technical solutions:
[0006] A folding door with good stability includes a mounting assembly. Movable door panel assemblies are slidably connected to both sides of one end of the front of the mounting assembly. Fixing components that are inserted into the interior of the mounting assembly are fixedly installed at the middle position of both sides of the two movable door panel assemblies.
[0007] As a further optimization of this utility model, the mounting component includes a rectangular fixing frame. Guide grooves are provided at one end of the top and bottom sides of the rectangular fixing frame. Limiting grooves are provided at both ends of the two guide grooves. Mounting sliders extending to the outside are slidably connected to both sides of the two guide grooves. Limiting sliders extending into and slidably connected to the two mounting sliders on the same side are fixedly installed at both ends of the two mounting sliders. Fixing grooves are provided on both sides of the top of the two mounting sliders and on both sides of the bottom of the other two mounting sliders.
[0008] As a further optimization of this utility model, the movable door panel assembly includes movable mounting frames placed inside two mounting sliders on the same side, and the top and bottom of the two movable mounting frames are fixedly installed with U-shaped slots that engage with the outside of the mounting sliders.
[0009] As a further optimization of this utility model, the fixing component includes mounting grooves fixedly opened on both sides of the two movable mounting frames. The inner top and inner bottom of the two mounting grooves on the same side are slidably passed through by fixing rods extending into the fixing groove. A spring connected to the fixing rod is fixedly installed at the middle position inside the two mounting grooves on the same side.
[0010] As a further optimization of this utility model, the bottom of the two mounting sliders and the top of the other two mounting sliders are provided with opening slots, and multiple rollers are rotatably installed inside the four opening slots, with the multiple rollers fitting into the interior of the guide groove.
[0011] As a further optimization of this utility model, a fixed door panel that fits into the movable mounting frame is threadedly fixed to one end of the back side of both sides inside the rectangular fixed frame. The fixed door panel includes a fixed mounting frame, and a glass plate is fixedly installed on the inner side of the fixed mounting frame.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. This utility model, through the structural design of the installation components, can effectively prevent the folding door from derailing during later pushing and pulling, thereby improving the stability of the folding door's later pushing and pulling operation. By using the sliding connection design between the installation slider and the guide groove, and then cooperating with the sliding connection between the limiting groove and the limiting slider, the stability of the installation slider sliding inside the guide groove can be improved, effectively preventing derailment. Compared with the traditional sliding connection of rollers and slide rails, it has a longer service life and more stable sliding.
[0014] 2. This utility model, through the structural design of the movable door panel assembly and the subsequent use of the fixing assembly, increases the convenience and flexibility for operators to assemble and disassemble the movable mounting frame. Moreover, it eliminates the need for alignment of the rollers and the track. Operators only need to slide the U-shaped slot and the mounting slider into place, and then use the fixing rod and the fixing groove to fix the movable mounting frame. This effectively increases the practicality of the operation for operators. Attached Figure Description

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0023] Example 1
[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, a folding door with good stability includes an installation component 1. The structural design of the installation component 1 facilitates the subsequent fixed installation of the folding door and its components. The installation component 1 includes a rectangular fixing frame 100. A fixed door panel 2 is threadedly fixed to one end of the back side of both sides inside the rectangular fixing frame 100. The fixed door panel 2 includes a fixed mounting frame. A glass plate is fixedly installed on the inner side of the fixed mounting frame. The structural design of the fixed door panel 2 improves the lighting performance of the folding door. Guide grooves 102 are provided at one end of the front side of the top and bottom of the rectangular fixing frame 100. Limit grooves 101 are provided at both ends of the two guide grooves 102. Mounting sliders 103 are slidably connected to the adjacent sides of the two guide grooves 102. Both ends of the two mounting sliders 103 on the same side are fixed. Limiting sliders 104 are installed, extending into and slidably connected to the limiting groove 101. Opening slots are provided at the bottom of two mounting sliders 103 and at the top of the other two mounting sliders 103. Multiple rollers are rotatably installed inside each of the four opening slots, and these rollers engage with the guide groove 102 to improve the smoothness of the mounting sliders 103's sliding and reduce friction. The installation design of the limiting groove 101 and limiting sliders 104 also limits the mounting sliders 103, effectively preventing them from derailing. Fixing slots 105 are provided on both sides of the top of two mounting sliders 103 and on both sides of the bottom of the other two mounting sliders 103, allowing for easy fixing of the folding door panel.
[0025] like Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the inner sides of the two mounting sliders 103 on the same side are each equipped with a movable door panel assembly 3 that cooperates with the mounting component 1 and the fixed door panel 2. The later push-pull operation of the folding door can be tested through the movable door panel assembly 3. Each of the two movable door panel assemblies 3 includes a movable mounting frame 300, and the two movable mounting frames 300 are located inside the two mounting sliders 103 on the same side. A glass plate 2 is fixedly installed inside each of the two movable mounting frames 300, facilitating the later operation of blocking and opening / closing the door from the inside and outside. An opening is located at the middle position of one of the two movable mounting frames 300 on the side closest to each other. The two movable mounting frames 300 have grooves, and the inner sides of the grooves are provided with anti-slip textures, which facilitates the operation of pushing and pulling the movable mounting frame 300 and its components by the operator. U-shaped slots 301 are fixedly installed at the top and bottom of both movable mounting frames 300, and the U-shaped slots 301 slide and engage with the outside of the mounting slider 103, facilitating the assembly of the movable mounting frame 300 and its components by the operator without requiring the operator to align the rollers with the slide rail. Fixing components 4 are installed at the middle position on both sides of the two movable mounting frames 300. The fixing component 4 facilitates the fixing and limiting of the movable mounting frame 300 and its components, allowing the movable mounting frame 300 to be fixedly connected to the mounting slider 103 via the U-shaped slot 301. This facilitates the subsequent driving and sliding operation of the mounting slider 103 via the movable mounting frame 300. The fixing component 4 includes mounting grooves 400 located at the middle of the two movable mounting frames 300. Fixing rods 402, extending into the inner side of the fixing groove 105, slide through the top and bottom of the two mounting grooves 400 on the same side. The insertion and connection of the fixing rod 402 and the fixing groove 105 facilitates the fixed installation of the movable mounting frame 300 and above. A spring 401 is welded and fixed in the middle position inside the two mounting grooves 400 on the same side. The middle position of the outer side of the spring 401 is welded and connected to the middle position inside the mounting groove 400. The top and bottom of the spring 401 are fixedly connected to the fixing rod 402. In the future, it is convenient to realize the compression displacement and automatic reset of the fixing rod 402, which in turn facilitates the subsequent driving of the fixing rod 402 to realize the insertion and connection of the fixing rod 402 with the fixing groove 105.
[0026] It should be noted that this type of folding door with good stability allows the operator to first fix the mounting component 1 and above to the designated position. Later, the operator can directly drive the movable mounting frame 300 through the groove, and then, through the fixed connection between the U-shaped slot 301 and the mounting slider 103, the mounting slider 103 can slide inside the guide groove 102. Then, the mounting slider 103 can drive the limiting slider 104 to slide inside the limiting groove 101, finally achieving stable push-pull operation by driving the movable mounting frame 300, effectively preventing derailment later on. When it is necessary to replace or repair the movable mounting frame 300, the operator can directly squeeze the fixing rod 402 through the mounting groove 400. Then, the fixing rod 402 can compress the spring 401 inside the mounting groove 400. Finally, the fixing rod 402 can be driven to disengage into the fixing groove 105, thereby releasing the fixed connection between the U-shaped slot 301 and the mounting slider 103. Then, the movable mounting frame 300 can be used to drive the U-shaped slot 301 to disengage from the outside of the mounting slider 103. This allows the operator to easily disassemble and repair the movable mounting frame 300 later.
[0027] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
