Description

Technical Field

[0001] The utility model relates to the technical field of swing doors, and more specifically, to a gap adjustment device for a swing door panel and a door frame. Background Art

[0002] In the current technical fields of automatic doors and swing doors of platform ladders, the installation and fixing methods of door panels are directly related to the overall performance of the door system and the user experience. Traditional installation methods mostly adopt the strategy of fixing both sides of the door frame in combination with fixing the door head and the floor sill up and down. This design simplifies the process during the manufacturing and shipping stages, but a series of problems are exposed in actual applications:

[0003] First of all, since the door panel and the door frame will inevitably be subjected to external forces such as vibration and collision during transportation, even if strict quality control is carried out at the factory, it is difficult to completely avoid slight deformations. After the installation is completed, these deformations often lead to uneven gaps between the door panel and the floor sill and the door head, which in turn cause abnormal noises and poor operation when opening and closing the door. These problems not only affect the normal function of the door system but also reduce the user experience. Secondly, a significant defect of the traditional installation method is its lack of flexibility in on-site adjustment. Once the door panel is installed, its position and gap are basically fixed and it is difficult to make fine adjustments. This means that any deformation or deviation that occurs during transportation or installation will directly affect the final installation effect. To solve these problems, it is often necessary to replace components or reinstall, which undoubtedly increases the installation cost and difficulty. Therefore, we make improvements in this regard and propose a gap adjustment device for a swing door panel and a door frame. Summary of the Invention

[0025] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] As recorded in the background art, since the door panel and the door frame will inevitably be affected by external forces such as vibration and collision during transportation, even if strict quality control is carried out during factory production, it is difficult to completely avoid slight deformations. After installation, these deformations often lead to uneven gaps between the door panel and the sill and the door head, which in turn cause abnormal noises and poor operation when opening and closing the door. These problems not only affect the normal function of the door system but also reduce the user experience; secondly, a significant defect of the traditional installation method is its lack of flexibility in on-site adjustment. Once the door panel is installed, its position and gap are basically fixed and it is difficult to make fine adjustments. This means that any deformation or deviation that occurs during transportation or installation will directly affect the final installation effect. To solve these problems, it is often necessary to replace components or reinstall, which undoubtedly increases the installation cost and difficulty.

[0027] To solve this technical problem, the present utility model provides a gap adjustment device for the flat door panel and the door frame.

[0028] Specifically, please refer to Figures 1-3 , the gap adjustment device for the flat door panel and the door frame specifically includes:

[0029] A sill main body 1 and a door panel main body 6. A sill embedded seat 2 is provided in the sill main body 1. A lower bearing fixing seat 3 is installed in the sill embedded seat 2. A bearing main body 4 is provided in the lower bearing fixing seat 3. A gap is left between the lower bearing fixing seat 3 and the sill embedded seat 2 to achieve the adjustment of the door panel main body 6 in the front and back directions.

[0030] The gap adjustment device for the swing door panel and the door frame provided by the present utility model allows for precise on-site adjustment of the gap of the door panel body 6, ensuring a uniform gap between the door panel body 6 and the sill body 1, effectively avoiding abnormal noises during door opening and closing and smooth operation problems, improving the user experience. Even if the door panel body 6 undergoes slight deformation during transportation or initial installation, it can be corrected without replacing components, reducing the installation difficulty and cost.

[0031] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0032] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0034] Embodiment 1, please refer to Figures 1-3 , a gap adjustment device for a swing door panel and a door frame, including a sill body 1 and a door panel body 6. A sill inlay seat 2 is provided in the sill body 1, a lower bearing fixing seat 3 is installed in the sill inlay seat 2, a bearing body 4 is arranged in the lower bearing fixing seat 3, and a gap is left between the lower bearing fixing seat 3 and the sill inlay seat 2 to realize the adjustment of the door panel body 6 in the front-rear direction. The present application allows for precise on-site adjustment of the gap of the door panel body 6, ensuring a uniform gap between the door panel body 6 and the sill body 1, effectively avoiding abnormal noises during door opening and closing and smooth operation problems, improving the user experience. Even if the door panel body 6 undergoes slight deformation during transportation or initial installation, it can be corrected without replacing components, reducing the installation difficulty and cost.

[0035] Furthermore, as Figure 3 shown, the gap is composed of a first gap H1 and a second gap H2. The first gap H1 and the second gap H2 are provided between the sill inlay seat 2 and the lower bearing fixing seat 3. Subdividing the gap into the first gap H1 and the second gap H2 is of great significance. This subdivision design makes the adjustment process more delicate and accurate. For example, when the deviation of the door panel body 6 in the front-rear direction is mainly concentrated on one side, precise correction can be achieved by separately adjusting the corresponding gap. Moreover, different gaps can be adjusted specifically for different degrees of deviation, so as to achieve a more accurate and ideal position adjustment of the door panel body 6.

[0036] Embodiment 2 further optimizes the gap adjustment device for the swing door panel and the door frame provided in Embodiment 1. Specifically, asFigure 2 As shown, a lower rotating shaft 5 of the door leaf is embedded in the bearing body 4 to achieve the adjustment of the door panel body 6 in the height direction, and the stroke of the height adjustment is Figure 2 marked as H3 in the figure. Adding the adjustment function of the door panel body 6 in the height direction brings many benefits. On the one hand, it makes the position adjustment of the door panel body 6 more comprehensive and accurate. In actual installation, the ground may be uneven or the installation height of the door needs to be fine-tuned according to special requirements. At this time, the adjustment in the height direction is crucial. On the other hand, this comprehensive adjustment function can better adapt to different installation conditions and requirements.

[0037] Furthermore, as Figure 1 and Figure 2 shown, the lower rotating shaft 5 of the door leaf is connected to the door panel body 6. The direct connection between the lower rotating shaft 5 of the door leaf and the door panel body 6 has significant advantages. First of all, this direct connection ensures that the adjustment force can be effectively transmitted to the door panel body 6 to achieve stable and reliable height adjustment. During the adjustment process, the loss or deviation of the adjustment force will not occur due to the looseness or error of the intermediate connection link, so that the door panel body 6 can be accurately adjusted to the required height position. Secondly, the direct connection improves the response speed and accuracy of the adjustment. When operating on the lower rotating shaft 5 of the door leaf, the door panel body 6 can quickly make corresponding movements and can achieve small and precise height changes to meet the high requirements for installation accuracy.

[0038] Furthermore, as Figure 1 shown, a door frame body 7 is arranged on the outer side of the door panel body 6, and the door frame body 7 is connected to the top of the floor sill body 1. The door frame body 7 significantly enhances the structural stability of the door panel body 6. It can bear the weight of the door panel itself and various forces generated during the opening and closing of the door, effectively preventing the deformation and distortion of the door panel body 6, and ensuring that the door panel body 6 maintains a good shape and performance during long-term use. Through the front-back, up-down adjustment of the door panel body 6, its adjustment with the door frame body 7 can be achieved.

[0039] Furthermore, as Figure 1 shown, a door panel glass 8 is arranged in the door panel body 6.

[0040] Furthermore, the door panel glass 8 is connected to the door panel body 6 through glue. The glue connection can provide a relatively firm connection effect. After the glue is cured, it can form a uniform bonding layer, tightly combine the door panel glass 8 and the door panel body 6 together, bear various stresses generated during the opening and closing of the door, and ensure the stability and reliability of the connection. Secondly, the operation is relatively simple, without the need for complex tools and equipment, reducing the installation difficulty and cost. The glue connection can also reduce the gaps and crevices at the connection part, improve the sealing performance and sound insulation effect of the door, and enhance the overall quality and performance of the door.

[0041] Example 3 further optimizes the gap adjustment device for the swing door panel and the door frame provided in Example 1 or 2. Specifically, as Figure 2 shown, a locking screw 501 is provided on the lower rotating shaft 5 of the door leaf. The locking screw 501 is used for locking the lower rotating shaft 5 of the door leaf after adjustment. It can ensure that the lower rotating shaft 5 of the door leaf maintains a stable position after adjustment. During the use of the door, it will be affected by frequent opening and closing actions and external factors. Without the locking screw 501, the lower rotating shaft 5 of the door leaf may displace, resulting in a change in the position of the door panel main body 6 and affecting the normal use of the door. The locking screw 501 provides a strong fixing force and effectively prevents this situation from occurring.

[0042] Furthermore, a locking mechanism is further included. The locking mechanism is used to fix the relative position between the lower bearing fixing seat 3 and the sill embedded seat 2 after adjustment to prevent unexpected movement and ensure the stability of the door panel main body 6. It effectively prevents unexpected movement between the lower bearing fixing seat 3 and the sill embedded seat 2 after adjustment. During the long-term use of the door, due to factors such as vibration and temperature change, there may be slight displacements between components. The locking mechanism can eliminate this possibility and ensure that the door panel main body 6 always remains in the adjusted stable position, thus ensuring the normal operation and performance of the door.

[0043] Furthermore, the locking mechanism includes at least one locking screw. The locking screw is used to lock the gap between the lower bearing fixing seat 3 and the sill embedded seat 2. Using the locking screw as a component of the locking mechanism has multiple advantages. The locking screw has a low cost, is easy to obtain and replace. During large-scale production and installation, it can effectively control costs and is also convenient for quick repair and replacement when needed. Secondly, it is easy to operate. The installer only needs to use simple tools, such as a screwdriver, to easily tighten or loosen the locking screw to achieve the locking and unlocking operations. In addition, the locking screw can provide a reliable locking effect.

[0044] Install the sill embedded seat 2, the lower bearing fixing seat 3, and the bearing main body 4 in the cavity of the sill main body 1. Fix the sill main body 1 and the door frame main body 7 with bolts. Seat the door panel main body 6 into the bearing main body 4 through the lower rotating shaft 5 of the door leaf. Adjust the gap between the lower bearing fixing seat 3 and the sill embedded seat 2 to adjust the position of the door panel main body 6 in the well depth direction to adjust the step difference between the surface of the door panel main body 6 and the inner surface of the well. Use a special tool or a flat screwdriver to engage with the spline groove of the lower rotating shaft 5 of the door leaf and rotate the lower rotating shaft 5 of the door leaf to adjust the height position of the door panel main body 6.
