Description

Technical Field

[0001] This utility model relates to the field of door stop technology, specifically a multifunctional door stop that can be extended and retracted to adapt to different door gap widths. Background Technology

[0002] A doorstop is an item used in daily life to prevent doors from being blown away by the wind when opening windows for ventilation, thus avoiding inconvenience. People usually find some wood blocks, bricks, heavy books, etc., and place them between the door and the ground, or in the gap between the door frame and the door leaf. By using these items to block the door, the range of movement is restricted, and the door is tightly fixed, so that the door can remain relatively stable and not easily blown away by the wind.

[0003] For example, an existing Chinese patent (CN202706727U) discloses a doorstop with a flexible handle at the tail of a wedge-shaped block. To increase the doorstop's friction, the front end of the wedge-shaped block has two through holes, each containing a rubber plug, the length of which is slightly longer than the length of the through holes. This doorstop, with its novel design, incorporates a flexible handle and rubber plugs, mimicking an animal's tail and eyes, thus possessing both practical function and decorative appeal. Furthermore, the rubber plugs can be exposed at the bottom of the wedge-shaped block to increase friction, while the flexible handle enhances ease of use. In summary, this doorstop is convenient to use, has a long lifespan, and is also decorative.

[0004] Currently available doorstops on the market typically have a fixed height. However, in actual use cases, due to factors such as door installation conditions and floor flatness, door gap heights often vary. This necessitates the use of doorstops of different heights to accommodate door gaps of varying sizes, and existing doorstops cannot meet diverse usage needs. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional door stop that can be extended and adapted to different door gap widths, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional doorstop that can extend and adapt to different door gap widths, comprising a base plate and triangular side plates. The triangular side plates are fixed on both sides of the base plate. The inner walls of both sides of the triangular side plates are provided with T-shaped grooves. An adjusting plate is slidably provided at the top of the T-shaped groove. A connecting rod is fixed on one side of the bottom of the adjusting plate. A fixing sleeve is fixed on the outer wall of the middle part of the connecting rod. A positioning rod is provided at the bottom end of the fixing sleeve. A triangular plate is provided at the center of the top of the base plate. An adjusting groove is opened at the top of the triangular plate. A rubber plate is provided at the top of the adjusting groove. A positioning hole is opened inside the rubber plate. The positioning rod can be inserted into the positioning hole.

[0007] Furthermore, the T-shaped groove is installed at an angle, and the top surface of the T-shaped groove is parallel to the top surface of the triangular side plate.

[0008] Furthermore, a T-shaped slider is slidably provided inside the T-shaped groove, and the bottom of the adjusting plate is fixed to the T-shaped slider.

[0009] Furthermore, the two ends of the connecting rod are fixed to the T-shaped slider, and the top of the adjusting plate is provided with a handle.

[0010] Furthermore, the top surface of the triangular plate is parallel to the top surface of the triangular side plate.

[0011] Furthermore, there are multiple positioning holes, which are equidistantly arranged inside the rubber sheet. A through groove is provided between the positioning holes, and the width of the through groove is smaller than the diameter of the positioning hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model, through the setting of a base plate, a triangular plate, and a rubber plate, enables the adjustment plate to be pulled by the handle when the door stop is in use. During the pulling process, the T-shaped sliding groove and the T-shaped slider cooperate to make the adjustment plate extend along the direction of the T-shaped sliding groove, thereby adjusting the height of the top of the adjustment plate and increasing the height of the entire door stop. This makes it suitable for use in door gaps of different heights and improves the multi-functional applicability of the door stop.

[0014] When the adjusting plate is pulled, it will drive the connecting rod and the positioning rod to move together, so that the positioning rod overcomes the resistance of the various through grooves and positioning holes in the rubber plate and reaches the positioning holes at different heights. The positioning of the positioning rod by the through grooves and positioning holes can prevent the adjusting plate from changing its height arbitrarily and ensure the stability of the door stop during use.

[0015] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a multi-functional doorstop that can extend and adapt to different door gap widths, including a base plate 1 and triangular side plates 2. The triangular side plates 2 are fixed on both sides of the base plate 1. The base plate 1 serves as the basic support component of the entire doorstop, providing an installation carrier for other components. The triangular side plates 2 fixed on both sides form a stable frame structure with the base plate 1. The triangular shape has good stability, which can enhance the overall strength and deformation resistance of the doorstop, making it less prone to damage when subjected to door pressure and external forces. At the same time, it provides space and position support for the installation of other components.

[0023] The inner walls of both sides of the triangular side plate 2 are provided with T-shaped grooves 3. An adjusting plate 5 is slidably mounted at the top of the T-shaped grooves 3. The T-shaped grooves 3 provide a specific track for the movement of the adjusting plate 5, ensuring that the adjusting plate 5 can only slide along the direction of the T-shaped grooves 3. This guarantees the stability and accuracy of the movement of the adjusting plate 5 and prevents it from deviating or shaking during movement, thereby ensuring the normal operation of the door stop height adjustment function. As a key component for height adjustment, the adjusting plate 5 can change its position in the door stop by sliding within the T-shaped grooves 3, thereby adjusting the overall height of the door stop to accommodate door gaps of different heights.

[0024] A connecting rod 7 is fixed to one side of the bottom of the adjusting plate 5. A fixing sleeve 8 is fixed to the outer wall of the middle part of the connecting rod 7. A positioning rod 9 is provided at the bottom end of the fixing sleeve 8. The connecting rod 7 not only connects the T-shaped slider 4, but also provides an installation position for the fixing sleeve 8. The fixing sleeve 8 is used to fix the positioning rod 9, so that the positioning rod 9 can move with the adjustment plate 5. The positioning rod 9 is a key component for the height positioning of the door stop. It can be inserted into the positioning hole 13 in the rubber plate 12 to fix the height of the adjusting plate 5, prevent the adjusting plate 5 from moving arbitrarily due to external forces during the use of the door stop, and ensure the stability of the door stop height.

[0025] A triangular plate 10 is located at the top center of the base plate 1. An adjustment groove 11 is formed at the top of the triangular plate 10, and a rubber plate 12 is located at the top of the adjustment groove 11. A positioning hole 13 is formed inside the rubber plate 12, into which a positioning rod 9 can be inserted. The triangular plate 10, positioned at the top center of the base plate 1, provides a mounting base for the rubber plate 12. The adjustment groove 11 provides sufficient space and position for the rubber plate 12, allowing it to be securely mounted on the triangular plate 10. The rubber plate 12 possesses good elasticity and friction. When the positioning rod 9 is inserted into its internal positioning hole 13, the rubber plate 12 can generate resistance to the positioning rod 9 through its own elasticity, enhancing positioning stability. Simultaneously, the rubber material reduces noise during the insertion and removal of the positioning rod 9, improving user comfort.

[0026] The T-shaped slide rail 3 is installed at an angle, with its top surface parallel to the top surface of the triangular side plate 2. This angled installation allows the adjusting plate 5 to move at a specific tilt angle during sliding. This design ensures that the doorstop better matches the bottom shape of the door when its height is adjusted, increasing the contact area between the doorstop and the door, and improving its blocking effect and stability. Simultaneously, the parallelism between the top surface of the T-shaped slide rail 3 and the top surface of the triangular side plate 2 ensures a smooth transition between the adjusting plate 5 and the top of the triangular side plate 2 at its highest position, resulting in a more aesthetically pleasing overall appearance of the doorstop and preventing potential scratches to the door or floor due to inconsistent heights.

[0027] A T-shaped slider 4 slides inside the T-shaped groove 3, and the bottom of the adjusting plate 5 is fixed to the T-shaped slider 4. The T-shaped slider 4 slides within the T-shaped groove 3, serving to connect and transmit motion. It connects the adjusting plate 5 to the T-shaped groove 3, allowing the adjusting plate 5 to slide smoothly within the T-shaped groove 3 via the T-shaped slider 4. This connection method is simple and reliable, can withstand a certain amount of force, ensures that the adjusting plate 5 will not fall off during sliding, and facilitates the height adjustment of the adjusting plate 5.

[0028] The connecting rod 7 is fixed at both ends to the T-shaped sliders 4, and the top of the adjusting plate 5 is equipped with a handle 6. The connecting rod 7 connects the T-shaped sliders 4 on both sides into a whole, enhancing the stability of the structure. When the adjusting plate 5 is pulled by the handle 6, the adjusting plate 5 drives the T-shaped sliders 4 to slide within the T-shaped groove 3. The connecting rod 7 ensures that the T-shaped sliders 4 on both sides move synchronously, thereby allowing the adjusting plate 5 to rise or fall smoothly and avoiding jamming or tilting of the adjusting plate 5 due to asynchronous movement on both sides. The handle 6 provides a convenient operating point for the user. The user can easily pull the adjusting plate 5 by holding the handle 6 to adjust the height of the door stop, improving the ease of use.

[0029] The top surface of the triangle 10 is parallel to the top surface of the triangle side plate 2. This design ensures that the positioning rod 9 remains within the adjustment groove 11 inside the triangle 10 during movement.

[0030] There are multiple positioning holes 13, which are equidistantly arranged inside the rubber plate 12. A through groove is provided between the positioning holes 13, the width of which is smaller than the diameter of the positioning hole 13. The positioning holes 13 provide precise positioning positions for the positioning rod 9. When the adjusting plate 5 is adjusted to the appropriate height, the positioning rod 9 is inserted into the corresponding positioning hole 13, accurately fixing the adjusting plate 5 at that height and preventing it from sliding down or moving up. This ensures that the door stop can stably adapt to door gaps of different heights during use, improving the reliability and practicality of the door stop. The multiple equidistant positioning holes 13 provide users with more height adjustment options. Users can insert the positioning rod 9 into different positions of the positioning hole 13 according to the actual door gap height, achieving fine adjustment of the door stop height and further improving its applicability. The width of the through groove between the positioning holes 13 is smaller than the diameter of the positioning holes 13. This design ensures that the positioning rod 9 can move smoothly from the through groove into the positioning hole 13. After the positioning rod 9 is inserted into the positioning hole 13, the through groove and the edge of the positioning hole 13 exert a certain constraint force on the positioning rod 9, preventing the positioning rod 9 from easily coming out of the positioning hole 13, thus enhancing the stability of the positioning.

[0031] When using the door stop, the adjustment plate 5 is pulled by the handle 6. During the pulling process, the adjustment plate 5 extends along the direction of the T-shaped slide 3 through the cooperation of the T-shaped slide 3 and the T-shaped slider 4, thereby adjusting the height of the top of the adjustment plate 5 and making the height of the entire door stop higher. This makes it suitable for use in door gaps of different heights and improves the multi-functional applicability of the door stop.

[0032] When the adjusting plate 5 is pulled, it will drive the connecting rod 7 and the positioning rod 9 to move together, so that the positioning rod 9 overcomes the resistance of the various through grooves and positioning holes 13 in the rubber plate 12 and reaches the positioning holes 13 at different heights. The positioning of the positioning rod 9 by the through grooves and positioning holes 13 can prevent the adjusting plate 5 from changing its height arbitrarily and ensure the stability of the door stop during use.

[0033] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
