[0002] Floor spring glass doors, as a common type of automatic closing door system, are widely used in commercial buildings, public places, and some residences. In commercial places such as shopping malls, hotels, and office buildings, their transparent glass material not only does not obstruct the view between the inside and outside, making the space appear open and spacious, but also fully showcases the interior environment and displays, attracting customers' attention. At the same time, the automatic closing function facilitates the entry and exit of people without the need for manual closing, improving the convenience of use.

[0003] A search revealed that Chinese patent CN206273988U discloses "a floor spring glass door, including a crossbeam, a floor spring, a pivot device, and symmetrically arranged left and right door panels. Each door panel includes tempered glass and a door frame. The door frame is composed of a top galvanized square tube, a bottom galvanized square tube, and two vertical galvanized square tubes fixedly connected end to end. The inner ends of the two vertical galvanized square tubes are fixedly connected to U-shaped slots, and the openings of the U-shaped slots are arranged opposite each other to allow the tempered glass to be placed in the door..." The door is positioned within the frame using a U-shaped slot to prevent the tempered glass from tilting; stainless steel plates are attached to the outer surface of each galvanized square tube to enhance the door's appearance; a floor spring is located at the bottom end of the bottom galvanized square tube to control the opening and closing of the left and right door panels; the pivot device includes a rotating main shaft and a bushing, with the main shaft vertically positioned and fixedly connected to the crossbeam, and the bushing vertically positioned on the upper end face of the top galvanized square tube. During assembly, the bushing is fitted onto the main shaft to allow the door panel to rotate around the main shaft. However, the following defects still exist: When this device is in use, a gap forms between the glass door and the frame during opening and closing. This gap can easily become a danger zone for children or careless adults. If a finger is accidentally inserted into the gap, the strong force generated when the glass door closes can quickly trap the finger, causing varying degrees of injury. This safety hazard not only causes physical pain to the user but also brings legal risks and financial compensation pressure to the venue manager. Therefore, a floor-spring glass door that prevents finger pinching is proposed. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] like Figure 1 and Figure 3 As shown, this embodiment proposes a floor spring glass door that can prevent hand pinching, including a frame 1, an anti-pinch component 2 that prevents hand pinching in the gap of the glass door is provided inside the frame 1, and a sealing component 3 that assists in sealing the gap of the glass door is provided on the inner wall of the frame 1. like Figure 2 and Figure 3As shown, the anti-pinch component 2 includes two floor springs 201 installed on the inner bottom wall of the frame 1. Each floor spring 201 has a fixed bracket 202 at its top, and each fixed bracket 202 is rotatably connected to an upper pivot 203. Through the cooperation of the floor springs 201 and the upper pivot 203, the glass door 204 can be better adapted to different opening angles and rotation speeds. Each fixed bracket 202 has a glass door 204 installed on its inner wall. Handles 205 are bolted to opposite sides of each glass door 204, facilitating easy opening and closing for the user. Side frames 206 are fixedly connected to opposite sides of the frame 1, providing precise guidance and positioning for the rotation of the glass door 204, preventing users' fingers from being pinched and thus providing safety protection. Dustproof plates 207 are fixedly connected to the bottom of each fixed bracket 202, preventing external debris from entering the room. The floor spring 201 serves as the power source and support foundation for the rotation of the entire glass door 204. It not only provides stable rotational support for the fixing frame 202, but also generates a reset force through its internal spring mechanism after the glass door 204 is opened. The floor spring 201 and the upper pivot 203 at the top of the fixing frame 202 cooperate to ensure that the glass door 204 can be opened and closed easily and freely. The handle 205 provides a convenient operating point for the user, greatly improving the convenience of use. The side frame 206 not only provides precise guidance and positioning for the rotation of the glass door 204, ensuring that the glass door 204 can open and close smoothly according to the predetermined trajectory, but also effectively prevents the user's fingers from being accidentally inserted into the gap and pinched when the glass door 204 is opened or closed, significantly improving the safety of use. The dustproof plate 207 at the bottom of the fixing frame 202 can block external debris from entering the room, avoiding pollution of the indoor environment, thereby greatly improving the stability and service life of the overall structure.

[0020] like Figure 3 As shown, the sealing assembly 3 includes a first magnetic sealing strip 301 that is slidably connected to the inner wall of the frame 1, and magnetic strips 302 are provided on the top of both fixing brackets 202. When the glass door 204 is closed, the first magnetic sealing strip 301 inside the frame 1 and the magnetic strips 302 inside the fixing brackets 202 are tightly attracted and adhered, thereby achieving auxiliary sealing of the gaps in the glass door 204. This effectively prevents air, dust, etc. from entering the room through the gaps in the glass door 204, improving the room's airtightness and cleanliness.

[0021] like Figure 5As shown, four limiting plates 4 are fixedly connected to the two opposing sides of the frame 1, and plastic pads 5 are provided on the side of each limiting plate 4 away from the frame. When the glass door 204 is opening and closing, the limiting plates 4 can restrict the opening and closing position of the glass door 204 and prevent the glass door 204 from being opened or closed excessively. The plastic pads 5 play a buffering role when the glass door 204 comes into contact with the limiting plates 4, reducing the noise and damage caused by the collision.

[0022] like Figure 4 As shown, each of the two mounting brackets 202 has a fixed post 6 fixedly connected to its bottom, and two rollers 7 are rotatably connected to the outer wall of each of the two fixed posts 6. When the glass door 204 rotates, the rollers 7 roll on the ground, reducing the friction between the mounting bracket 202 and the ground, making the rotation of the glass door 204 easier and smoother, and greatly extending the service life of the mounting bracket 202.

[0023] like Figure 5 As shown, each of the two glass doors 204 has a connecting frame 8 on one side, and each of the adjacent sidewalls of the two connecting frames 8 has a second magnetic sealing strip 9. When the two glass doors 204 are closed, the second magnetic sealing strips 9 attract each other, sealing the gap between the two glass doors 204, further improving the sealing performance of the glass doors 204, effectively preventing dust and other contaminants from entering the room through the gap between the two glass doors 204, and enhancing the sealing effect of the room.

[0024] like Figure 5 As shown, three baffles 10 are fixedly connected to one side of the two fixed brackets 202, and the three baffles 10 are circumferentially distributed along the central axis of the fixed brackets 202. When the glass door 204 is opened or closed, the baffles 10 move with the rotation of the fixed plate 11, further blocking the gaps in the side frame 206, making the overall appearance of the glass door 204 and the fixed brackets 202 more aesthetically pleasing, while also providing a certain degree of protection.

[0025] like Figure 2 As shown, multiple fixing plates 11 are fixedly connected to both sides of the two fixing frames 202, and the fixing plates 11 are evenly distributed along the height direction of the fixing frames 202. The fixing plates 11 can increase the structural strength of the fixing frames 202, making the fixing frames 202 more stable when bearing the weight of the glass door 204 and the force during rotation, and less prone to deformation. This greatly improves the structural stability of the fixing frames 202, ensures the safety of the installation and use of the glass door 204, and extends the service life of the glass door 204.

[0026] Specifically, in use, the floor spring glass door, designed to prevent finger pinching, features the following: The floor spring 201 serves as the power source and support for the rotation of the entire glass door 204. It not only provides stable rotational support for the fixing frame 202 but also generates a restoring force through its internal spring mechanism after the glass door 204 is opened. The floor spring 201 and the upper pivot 203 at the top of the fixing frame 202 work together to ensure that the glass door 204 can open and close easily and smoothly. The side frame 206 provides precise guidance and positioning for the rotation of the glass door 204, ensuring that the glass door 204 opens and closes smoothly along a predetermined trajectory. It also effectively prevents users from accidentally inserting their fingers into the gap and getting pinched when the glass door 204 is opened or closed, significantly improving safety. The dustproof plate 207 at the bottom of the fixing frame 202 prevents external debris from entering the room, avoiding pollution of the indoor environment (e.g., dust from outside objects entering the room). Figure 2 and Figure 3 (As shown); when the glass door 204 is closed, the first magnetic sealing strip 301 inside the frame 1 and the magnetic strip 302 inside the fixed frame are tightly attracted and adhered, thereby achieving auxiliary sealing of the gaps in the glass door 204. This effectively prevents air, dust, etc., from entering the room through the gaps in the glass door 204, improving the room's airtightness and cleanliness (e.g. Figure 3 (as shown in the figure), thereby significantly improving the stability and service life of the overall structure.

[0027] All technical features in this embodiment can be freely combined according to actual needs.

[0028] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
