[0001] This utility model relates to the field of unit door threshold technology, specifically a unit door threshold that facilitates entry and exit. Background Technology

[0002] The threshold of a unit door, also known as a door sill, is a small protrusion installed below the unit door. Its main function is to transition between the height difference between the inside and outside of the door, prevent water or dust from entering the room, and provide a certain degree of security. Although door thresholds are common in architectural design, their height, material, and function will vary depending on different design requirements.

[0003] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. The height of the existing ordinary unit door threshold is fixed and cannot be flexibly adjusted according to the diverse needs of actual use scenarios, which makes it unsuitable for different ground conditions or special passage requirements; 2. The existing ordinary unit door threshold is mostly rectangular in shape, which causes inconvenience for wheeled devices such as wheelchairs, strollers, and trolleys to cross the threshold in actual use. Utility Model Content

[0004] The purpose of this utility model is to provide a unit door threshold that facilitates entry and exit, thereby solving the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a unit door threshold that facilitates entry and exit, comprising a mounting assembly, an adjusting assembly mounted on the top of the mounting assembly, and a movable assembly mounted on the inner wall of the adjusting assembly.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a unit door threshold for easy access, including an installation component 1, an adjustment component 2 installed on the top of the installation component 1, and a movable component 3 installed on the inner wall of the adjustment component 2.

[0025] Mounting assembly 1 includes a base plate 101, on the top of which are mounted an insert block 102 and an adjusting block 103.

[0026] The adjustment component 2 includes a housing 201, and a first rubber sealing sheet 202 is installed at the front end of the housing 201.

[0027] The active component 3 includes a support plate 301, a number of springs 302 are installed on the top of the support plate 301, an L-shaped plate 303 is installed on the top of the springs 302, a connecting rod 304 is rotatably installed through one side of the L-shaped plate 303, sliding blocks 305 are installed on both sides of the L-shaped plate 303, and a second rubber sealing sheet 306 is installed at the front end of the L-shaped plate 303.

[0028] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the inserts 102 are symmetrically distributed about the vertical center line of the base plate 101. The bottom of the outer shell 201 and near both sides are provided with slots whose internal dimensions are consistent with the external dimensions of the inserts 102, and the inserts 102 are slidably installed in the slots. When adjusting the height of the adjusting component 2, the outer shell 201 slides on the two inserts 102 when the adjusting component 2 is moved up and down, which can improve the stability when adjusting the height of the adjusting component 2.

[0029] In this embodiment, as Figure 3 and Figure 5As shown, both the outer shell 201 and the top of the L-shaped plate 303 are provided with anti-slip textures; the anti-slip textures can increase the friction between the sole of the shoe and the top surface of the ledge. When someone steps on the top of the ledge, the anti-slip textures can play a role in preventing slipping and falling.

[0030] In this embodiment, as Figure 3 As shown, the rear end of the outer casing 201 is provided with a slope; the slope on the outer casing 201 facilitates wheeled equipment such as wheelchairs, strollers, and trolleys to pass over the bottom step. The wheeled equipment can be easily pushed along the slope without lifting it, reducing the obstruction and difficulty when passing over the bottom step.

[0031] In this embodiment, as Figure 2 and Figure 3 As shown, the front end of the adjusting block 103 is provided with several evenly spaced screw holes, and there are several adjusting blocks 103 in total. The adjusting blocks 103 are evenly spaced on the top of the base plate 101. The rear end of the outer shell 201 is provided with several evenly spaced screw holes. The height of the outer shell 201 can be adjusted as needed. Then, bolts are used to fix the position of the outer shell 201 through the screw holes on the outer shell 201 and the adjusting block 103, thereby improving the applicability of the bottom sill when used.

[0032] In this embodiment, as Figure 3 , Figure 4 and Figure 5 As shown, the support plate 301 and the connecting rod 304 are installed on the inner wall of the housing 201, and the springs 302 are evenly distributed at the top of the support plate 301. When the wheeled equipment moves from front to back, the L-shaped plate 303 is pushed and squeezed to rotate, and several springs 302 are compressed, so that the L-shaped plate 303 forms a slope, which facilitates the wheeled equipment to pass smoothly through the bottom sill.

[0033] In this embodiment, as Figure 3 , Figure 4 and Figure 5 As shown, both sides of the inner wall of the outer shell 201 are provided with arc-shaped grooves, and the sliding block 305 is slidably installed in the arc-shaped grooves. The rear end of the L-shaped plate 303 and the top of the inner wall of the outer shell 201 are provided with inclined surfaces. When the L-shaped plate 303 rotates, the sliding block 305 slides in the arc-shaped grooves of the inner wall of the outer shell 201, which can improve the stability of the L-shaped plate 303 when rotating, and at the same time limit the L-shaped plate 303, so that when the L-shaped plate 303 is subjected to the elastic force of the spring 302, it can close with the outer shell 201. When the L-shaped plate 303 is squeezed, it can form a suitable slope.

[0034] The usage method and advantages of this utility model: The working process of this convenient entry and exit unit door threshold is as follows:

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the outer casing 201 is first moved upwards, and the outer casing 201 slides on the two insert blocks 102. After the outer casing 201 is adjusted to a suitable height, several bolts are used to fix the position of the outer casing 201 through the screw holes on the outer casing 201 and the adjusting block 103. When entering or exiting the unit door and passing the bottom sill, when the wheeled equipment is moved forward from the rear end of the bottom sill, the wheeled equipment can easily pass through the bottom sill along the slope at the rear end of the outer casing 201. When the wheeled equipment is moved backward from the front end of the bottom sill, the L-shaped plate 303 is pushed, squeezed and rotated by the wheeled equipment, and several springs 302 are compressed. The wheeled equipment passes smoothly through the slope formed by the L-shaped plate 303.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
