[0030] Next, refer to Figures 1 to 3 A heavy-duty floor spring according to an embodiment of the present invention will be described in detail with specific embodiments. It should be understood that the following description is only an exemplary illustration and not a specific limitation to the invention.

[0031] Refer to Figures 1 to 3 , an embodiment of the present invention provides a heavy-duty floor spring, including an outer shell 110, a bearing component, a floor spring body 200, a panel, and an adjustment assembly.

[0032] Among them, the outer shell 110 is used to be embedded in the cement floor. During installation, a placement groove is usually opened on the cement floor, and the outer shell 110 is placed in the placement groove; the floor spring body 200 is installed in the outer shell 110 and plays a major functional role. The bearing component includes a bearing and a bearing seat. The bearing is installed on the bearing seat, and the bearing seat is fixedly connected to the outer shell 110 for assisting rotation. The floor spring body 200 is provided with a rotating shaft 210, and the rotating shaft 210 passes through the bearing and the bearing seat and is connected to the door body. The panel is arranged above the outer shell 110, and through holes corresponding to the bearing component are arranged on the panel. The panel is fixedly connected to the floor spring body 200 to prevent dust from entering, improve the use stability, and improve the aesthetics. The adjusting component abuts against the floor spring body 200 and the outer shell 110 respectively, and is used to finely adjust the position of the floor spring body 200 and fix the floor spring body 200 so that the turning position of the door body is accurate.

[0033] Refer to Figure 1 , specifically, the outer shell 110 is a box shape with an open upper end. The outer shell 110 is divided into a first area and a second area. The second area is higher than the first area, forming a stepped structure. The bearing seat is fixed on the first area of the outer shell 110 by a first screw. Among them, a pressing block is also arranged between the first screw and the bearing seat for finely adjusting the bearing seat. A dust-proof cover plate 120 is arranged in the second area of the outer shell 110. One end of the dust-proof cover plate 120 facing the bearing seat is folded downwards, and the top of the bearing seat is flush with the top of the dust-proof cover plate 120, which can cover the floor spring body 200 in the second area, prevent dust from entering, improve the use stability, and also play a certain aesthetic role.

[0034] The panel includes a first panel 410 and a second panel 420. The first panel 410 and the second panel 420 are arranged above the bearing seat. A through hole corresponding to the bearing component is arranged at the connection of the first panel 410 and the second panel 420. The first panel 410 and the second panel 420 are connected to the floor spring body 200 by second screws. By providing the first panel 410 and the second panel 420, the contact area between the door body and the heavy-duty floor spring is increased, the load-bearing capacity of the heavy-duty floor spring is improved, and at the same time, accessories such as the bearing and the bearing seat can be covered to prevent dust from entering, improve the use stability, and improve the aesthetics.

[0035] It should be noted that the bearing seat can also be arranged in the outer shell 110. At this time, the outer shell 110 and the bearing seat are fixedly connected on the side. However, due to the heavy weight of the door body, this solution will cause the use stability of the heavy-duty floor spring to deteriorate and shorten the service life of the heavy-duty floor spring.

[0036] It can be understood that the bearing housing includes a bottom plate 310 and a mounting member 320. The mounting member 320 is a cylinder with openings at the top and bottom. A groove adapted to the mounting member 320 is provided on the bearing housing. The bottom plate 310 is mounted on the first region, and the bearing is installed inside the mounting member 320. By setting the bearing housing as a split type, it is convenient for processing and improves work efficiency. It is easy to think that the bottom plate 310 and the mounting member 320 can also be integrally formed, but this solution is troublesome to process, increases labor intensity, and reduces production costs.

[0037] It should be noted that the bearing housing can also be a bottom plate 310 with a bearing installation position inside, but the bearing housing using this solution has a large thickness and an increased weight, resulting in an increase in the weight of the heavy-duty floor spring.

[0038] It is easy to think that a top rubber 350 is provided on the bottom plate 310, and the top of the top rubber 350 is flush with the top of the mounting member 320. Refer to Figure 1 and Figure 3 , there is a certain interval between the first panel 410, the second panel 420 and the bottom plate 310 of the bearing housing. Due to the heavy weight of the door body, it is easy to deform the first panel 410 and the second panel 420, affecting the use stability. Therefore, a top rubber 350 is provided in the interval between the first panel 410, the second panel 420 and the bearing housing, giving a certain support to the first panel 410 and the second panel 420, and improving the use stability of the heavy-duty floor spring.

[0039] Refer to Figure 1 and Figure 3 , the bearing includes a radial bearing 330 and a thrust bearing 340. The radial bearing 330 is in close contact with the mounting surface of the bearing housing, and the thrust bearing 340 is installed above the radial bearing 330. Using the combination of the radial bearing 330 and the thrust bearing 340 is beneficial to increase the load-bearing capacity and make the door body rotate conveniently. Of course, it can also be the combination of two thrust bearings 340, but due to the small thickness of the thrust bearing 340, the weight of the door body that it can bear is low; it can also be the combination of two radial bearings 330, but the radial bearing 330 has a large thickness, making the height of the bearing housing too high and the height of the housing also increasing, thus affecting the rotation of the door body.

[0040] It is easy to think that a second gasket can also be provided at the top of the bearing, which can prevent dust from entering the bearing, improve the use stability, and also extend the service life of the bearing.

[0041] Refer to Figure 3A first gasket 220 is provided between the rotating shaft 210 and the floor spring body 200. The connecting end of the rotating shaft 210 and the floor spring body is a square cone structure, so that there is a non-contact area between the floor spring body 200 and the rotating shaft 210. Therefore, the first gasket 220 is provided to facilitate the contact connection between the rotating shaft 210 and the floor spring body 200 and improve the stability of the connection.

[0042] Reference Figure 1 and Figure 3 The adjustment assembly includes a first adjustment assembly 510 and a second adjustment assembly 520. The first adjustment assembly 510 and the second adjustment assembly 520 are respectively arranged at two ends of the floor spring body 200. The first adjustment assembly 510 and the second adjustment assembly 520 are respectively in contact with the floor spring body 200 and the housing 110. The horizontal position of the floor spring body 200 in the housing 110 is finely adjusted by the first adjustment assembly 510 and the second adjustment assembly 520, thereby increasing the use effect of the heavy floor spring.

[0043] The first adjustment assembly 510 includes a first adjustment seat, a first adjustment plate and a first adjustment screw. One side of the first adjustment seat abuts against the ground spring body 200, and the other side abuts against the bottom of the accommodating cavity. Specifically, the ground spring body 200 is provided with a first adjustment hole. The first adjustment seat is a box-shaped structure with an opening at the bottom and a first elongated hole at the top, and the first adjustment seat abuts against the housing 110. The first adjustment plate is arranged in the first adjustment seat, and the first adjustment screw passes through the first adjustment hole and the first elongated hole, cooperates with the first adjustment plate to lock, and the end abuts against the bottom of the housing 110, so that the first adjustment assembly 510 is fixed between the ground spring body 200 and the bottom of the housing 110, so that the ground spring body 200 is fine-tuned by adjusting the first adjustment screw.

[0044] The second adjustment assembly 520 includes a second adjustment seat, a second adjustment plate and a second adjustment screw. The floor spring body 200 is provided with an extension portion outwardly, and the extension portion is provided with a second adjustment hole. The second adjustment seat is a box-shaped structure with an opening at the bottom and a second elongated hole at the top, and a slot is provided on the side. The second adjustment seat is abutted against the bottom of the housing 110, and the second adjustment plate is installed in the second adjustment seat and the two ends are movably inserted in the slot. The second adjustment screw passes through the second adjustment hole and the second elongated hole and is locked with the second adjustment plate, so that the second adjustment assembly 520 is fixed between the floor spring body 200 and the bottom of the housing 110, so that the floor spring body 200 can be fine-tuned by adjusting the second adjustment screw.

[0045] During installation, the heavy-duty floor spring is connected to the door body through the rotating shaft 210, so that the door body abuts against the top of the bearing and the housing 110, thereby transferring part of the weight of the door body to the housing 110 and the bearing, reducing the bearing weight of the heavy-duty floor spring, improving the load-bearing performance, and extending the service life of the heavy-duty floor spring. The heavy-duty floor spring according to the embodiment of the present invention can bear a door body with a relatively large weight, improve the use stability, and extend the service life.
