Description

Technical Field

[0001] The utility model belongs to the technical field of home decoration hardware and relates to an elastic door stopper. Background Art

[0002] A door stop is a device that holds the door in place after it is opened to prevent the wind from blowing or touching the door leaf and causing it to close.

[0003] The applicant previously applied for a hidden door stop with authorization announcement number CN218206271U, which includes a base body, wherein a positioning column and a door stop column are connected to the base body, which can move up and down relative to the base body. The positioning column always has a tendency to move upward, and a rocker arm is provided in the base body. The middle part of the rocker arm is hinged to the base body, one end of the rocker arm is tilted and located below the positioning column, and the other end of the rocker arm is located below the door stop column. When the door body drives the positioning column to move downward, it can drive one end of the rocker arm to move downward, and the other end of the rocker arm drives the upper end of the door stop column to extend out of the base body.

[0004] The above-mentioned door stop has a beautiful appearance and can produce a door-blocking effect, but it still has some shortcomings: the positioning column itself has a certain height, and the upper end of the positioning column is subjected to a horizontal thrust when it interacts with the door body, which sometimes easily causes a large force to be generated between the outer periphery of the positioning column and the seat body, and the positioning column is blocked from moving downward, thereby affecting the stable performance of the door-blocking positioning function. Summary of the Invention

[0005] The utility model aims at the above-mentioned problems existing in the existing technology and provides an elastic door stop. The technical problem to be solved by the utility model is that the existing door stop is unstable when playing the role of blocking and positioning the door.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] An elastic door stop comprises a base body, to which is rotatably connected a door-stop rocker in the shape of a strip and whose end can swing up and down, the bottom of one end of the door-stop rocker abuts against the base body, and the other end of the door-stop rocker is tilted upward, and is characterized in that one end of the door-stop rocker has a door-stop portion arranged upward, and the other end of the door-stop rocker has a positioning portion arranged from bottom to top toward the side where the door-stop portion is located, and the positioning portion can move downward to drive the door-stop portion to move upward and above the positioning portion.

[0008] The seat body is used to be installed on the ground, by providing an upward door-stop part at one end of the door-stop rocker and a positioning part inclined toward the side where the door-stop part is located at the other end of the door-stop rocker that is inclined upward. In this way, when the door body is opened and moves to the door-stop rocker, it can first contact the positioning part. Since the positioning part is inclined, the edge of the bottom surface of the door body can continue to move along the positioning part. At the same time, since the door-stop rocker is hinged on the seat body, the positioning part can be synchronously and smoothly swung downward around the hinge position, thereby driving the door-stop part to move upward and above the positioning part. The door body continues to move and is blocked by the door-stop part. When the door body contacts the door-stop part, the positioning part can also maintain contact with the bottom surface of the door body to ensure the positioning effect and prevent the door body from bouncing open easily. During the whole process, the positioning part will not be affected by friction and cause jamming, thereby ensuring that the door-stop positioning effect of the door collision is stably realized.

[0009] In the above elastic door stop, the positioning portion is formed by bending the other end of the door stop plate toward the side where the door stop portion is located. In this way, the positioning portion is directly formed by the end of the plate-shaped door stop plate through a bending process, which reduces processing efficiency and cost.

[0010] In the above elastic door stop, the door stop portion is formed by bending one end of the door stop rocker plate upward. Similarly, the door stop is directly formed by bending the end of the plate-shaped door stop rocker plate, which effectively improves processing efficiency and reduces process costs.

[0011] In the above elastic door stop, the top of the positioning portion is processed with an arc transition, which helps to reduce the resistance of the positioning portion during sliding along the bottom surface of the door body and avoid scratching the door body.

[0012] In the above elastic door stop, the side edge of the positioning portion close to the door stop portion is bent downwards. This is conducive to forming an arc transition at the top of the positioning portion through a bending process, which is lower in cost than grinding or cutting.

[0013] In the above-mentioned elastic door stop, the positioning portion always tends to move upward. This helps to ensure the abutting pressure between the positioning portion and the door body after it moves to the bottom surface of the door body, making the positioning portion's positioning effect on the door body more stable, and also helps the door rocker to quickly and smoothly return to its original position after the door body is closed.

[0014] In the above-mentioned elastic door stop, the base is connected to an upwardly disposed compression spring, the upper end of which is opposite to the bottom of the other end of the door stop rocker. In this way, the compression spring can provide an upward force for the positioning portion, and the compression spring is installed in the exposed area for easier assembly.

[0015] As another solution, a torsion spring is provided at the junction of the door stop plate and the base, with two free ends acting on the bottom of the other end of the door stop plate and the top surface of the base, respectively. In this way, the torsion spring ensures the upward movement of the positioning portion, while the structure is compact and not easily affected by external interference.

[0016] As another solution, the positioning portion is elastic and can bend and deform under pressure. In this way, when the positioning portion is subjected to the force of the door body, it can adaptively deform and slide relative to the door body. After moving downward, the deformation generated by the positioning portion can generate a continuous pushing force on the bottom surface of the door body, thereby ensuring positioning stability, while also making the structure more streamlined and reducing costs.

[0017] In the aforementioned elastic door stop, the base comprises a base and a movable plate that slides horizontally on the base. A door-stop rocker is rotatably connected to the top of the movable plate, with the rotation axis of the door-stop rocker perpendicular to the sliding direction of the movable plate. An elastic member is provided between the movable plate and the base to prevent the movable plate from moving toward the door stop. In this manner, when the door body collides rapidly with the door stop, the door-stop rocker can drive the movable plate to move. At this time, the elastic member, which can be a spring, a soft material, or a damper, can absorb the impact of the door body through compression, achieving a buffering effect to prevent damage to the door body or the door itself.

[0018] Compared with the prior art, the advantages of the present invention are as follows:

[0019] The movement direction of the elastic door-stop positioning part is guided by the door-stop rocker hinged on the base body, so that the positioning part moves downward more smoothly when subjected to force, and can stably realize the door-stop and positioning functions. In addition, the door-stop part and the positioning part are both arranged on the door-stop rocker and can be easily assembled from the outside. Under the condition of meeting the door-stop function requirements, the overall functional component structure is streamlined and the manufacturing cost is lower. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments. Example 1:

[0029] like Figure 1-4 As shown, the elastic door stop includes a base 1, to which is rotatably connected a door stop rocker 2 in the shape of a strip, the end of which can swing up and down. The door stop rocker 2 is a metal part, and the bottom of one end of the door stop rocker 2 abuts against the base 1. The other end of the door stop rocker 2 is tilted upward. One end of the door stop rocker 2 has a door stop portion 21 arranged upward, and the other end of the door stop rocker 2 has a positioning portion 22 arranged from bottom to top toward the side where the door stop portion 21 is located. The positioning portion 22 can move downward to drive the door stop portion 21 to move upward and be higher than the positioning portion 22. The bottom surface of the existing door body is often provided with a positioning groove that can cooperate with the positioning portion 22 to achieve a better positioning effect. The base 1 is used to be installed on the ground. As a preference, the positioning portion 22 is formed by bending the other end of the door stop rocker 2 toward the side where the door stop portion 21 is located, and the door stop portion 21 is formed by bending one end of the door stop rocker 2 upward. The side edge of the positioning portion 22, which is located near the door-blocking portion 21, is bent downward, forming a circular arc on the top surface of the positioning portion 22. An upwardly directed compression spring 3 is connected to the base 1, with the upper end of the compression spring 3 facing the bottom of the other end of the door-blocking rocker 2, so that the positioning portion 22 always tends to move upward. Specifically, the base 1 includes a base 11 and a movable plate 12 that is horizontally slidably connected to the base 11. The door-blocking rocker 2 is rotatably connected to the top of the movable plate 12. The rotation axis of the door-blocking rocker 2 is perpendicular to the sliding direction of the movable plate 12. An elastic member 5 is provided between the movable plate 12 and the base 11 to prevent the movable plate 12 from moving toward the door-blocking portion 21. The elastic member 5 is a conventional spring member. Example 2:

[0030] like Figure 5 As shown, this embodiment is basically the same as the first embodiment, except that: a torsion spring 4 is provided on the outer periphery of the hinge axis at the junction of the door rocker 2 and the base 11, with two free ends acting on the bottom of the other end of the door rocker 2 and the top surface of the movable plate 12 respectively, so that the positioning portion 22 always has a tendency to move upward. Example 3:

[0031] This embodiment is basically the same as the first embodiment, except that the positioning portion 22 is a metal spring having elasticity, and can bend and deform under pressure.

[0032] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
