Description

Technical Field

[0001] The utility model relates to a device for preventing a door leaf from closing unexpectedly, in particular to a door stop limiting device. Background Art

[0002] Exterior swing doors are a common door structure, widely used in exterior entrances and exits of residences, factories, public facilities, and other places. Existing exterior swing doors are typically equipped with ground plugs to maintain the door leaf in the open position and prevent it from accidentally closing. However, after prolonged use, if the concrete foundation surrounding the door body settles or the door leaf deforms slightly, the ground plugs can no longer effectively secure the door leaf. This can cause the door leaf to close automatically due to gravity or strong winds, potentially causing collision damage to passing vehicles and personnel. Utility Model Content

[0003] In order to solve the above deficiencies in the prior art, the present invention aims to provide a door stop limiting device to prevent the door leaf from closing accidentally.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a door stop limit device, comprising a limit pile and a limit striker used in conjunction to keep the door in an open state;

[0005] The limiting pile includes a fixed pile for pre-embedded in the ground, a limiting ring groove fixed on the top of the fixed pile, and a retaining ring suspended in the limiting ring groove by a limiting ring retaining rod; the limiting ring retaining rod is fixed at a position one-third of the distance from the front end of the limiting ring groove and is arranged along the width direction of the limiting ring groove;

[0006] The limiting striker is used for being installed on the door, and its height corresponds to the height of the retaining ring.

[0007] As a limitation of the present invention, the position-limiting striker includes a position-limiting bolt for installation on the door.

[0008] As another limitation of the present invention, the position-limiting impact member includes a mounting plate for mounting on the door and a position-limiting ring fixed on the mounting plate and used for sleeved on the retaining ring.

[0009] As a further limitation of the present invention, the limiting ring is a U-shaped ring.

[0010] As a third limitation of the present invention, the fixing pile includes a connecting plate and embedded fixing pipes fixed at both ends of the connecting plate;

[0011] The limiting ring groove is fixed in the middle of the connecting plate and is perpendicular to the surface of the connecting plate.

[0012] As a further limitation of the present invention, the limiting ring groove is a U-shaped groove.

[0013] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0014] (1) The structure of the present invention is ingeniously designed. Through the interaction of the limiting pile and the limiting impact piece, the door leaf can be restricted in the open state, preventing accidental closing and collision damage to passing vehicles and people. Regardless of whether the door leaf undergoes significant deformation or the concrete foundation settles, the present invention can effectively fix the door.

[0015] (2) The utility model is small in size, does not occupy road area, and does not affect the normal passage of vehicles. In addition, the utility model is simple and quick to operate. When opening the door, the limit striker moves to contact the retaining ring, and the retaining ring is subjected to horizontal thrust and rolls upward over the limit striker. When a gap larger than the diameter of the retaining ring is formed between the limit striker and the limit ring groove, the retaining ring falls back under the action of gravity, limiting the position of the limit striker and thus preventing the door leaf from closing. When closing the door, there is no need to bend over to operate. You only need to lift the retaining ring upward with your feet to separate the limit striker and the retaining ring, and then the door leaf can be closed.

[0016] The utility model is easy to process, simple to install, strong and durable, and is suitable for various outdoor swing doors. It is used to prevent the door from closing automatically and ensure the safety of people and vehicles passing through. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and understand the present invention and are not intended to limit the present invention.

[0026] This embodiment discloses a door stop limiting device, such as Figure 1 As shown, the embodiment includes a limit post 1 and a limit striker, which cooperate to limit the door leaf of the swing door to an open state, preventing it from accidentally closing and causing collision damage to passing vehicles and people. The limit post 1 and the limit striker in this embodiment are both welded from metal components, which are easy to obtain, low in cost, simple to manufacture and install, and have a strong and durable structure.

[0027] Specifically, such as Figure 2 As shown, the limit pile 1 includes a fixed pile 2, a limit ring groove 3, a limit ring retaining rod 4, and a retaining ring 5. The fixed pile 2 is used to be pre-buried in the ground and includes a connecting plate 101 and an embedded fixed pipe 102 fixed at both ends of the connecting plate 101 and extending vertically downward. The limit ring groove 3 is fixed in the middle of the connecting plate 101 and is a U-shaped groove with both ends fixed vertically to the surface of the connecting plate 101. The limit ring retaining rod 4 is fixed in the limit ring groove 3 and arranged along the width direction of the limit ring groove 3. The limit ring retaining rod 4 is fixed at a position one-third of the distance from the front end of the limit ring groove 3. The retaining ring 5 is a steel ring structure that is sleeved on the limit retaining rod and is a limit structure suspended in the limit ring groove 3. Under the action of its own gravity, the bottom of the retaining ring 5 is lower than the bottom of the limit ring groove 3.

[0028] In actual use, the fixing piles 2 can be pre-buried in the ground by pouring a concrete foundation, or the fixing piles 2 can be fixed on the ground by drilling holes with a water drill.

[0029] Since the retaining ring 5 is suspended at one-third of the front end of the limiting ring groove 3 by the limiting stop rod, the front end of the limiting ring groove 3 is in contact with the retaining ring 5, and the rear side of the limiting ring groove 3 has a gap for the retaining ring 5 to move. Therefore, when a backward horizontal thrust is applied, the retaining ring 5 can use the limiting ring stop rod 4 as an axis and roll upward to the inside of the limiting ring groove 3 until the bottom of the retaining ring 5 is basically level with the bottom of the limiting ring groove 3; when a forward horizontal thrust is applied, the retaining ring 5 is blocked by the front end of the limiting ring groove 3 and cannot move. It should be noted that the "front" and "rear" defined here are based on Figure 1 The symbols in are used only for explaining and understanding this embodiment and are not used to limit this embodiment.

[0030] The limit striker is used to be installed on the door, and its height corresponds to the height of the retaining ring 5. Figure 4 and Figure 5As shown. The limit impact piece can be any of the following structures:

[0031] A. The limit striker is a limit bolt 6 formed by cutting a metal rod. Figure 5 As shown, it is welded to the bottom of the door, with 5-7 cm exposed. When the door is opened, the limit pin 6 applies an inward thrust to the retaining ring 5, causing the retaining ring 5 to roll upward and over the limit pin 6. When the distance between the front end of the limit ring groove 3 and the limit pin 6 is greater than the diameter of the retaining ring 5, the retaining ring 5 falls back under the action of gravity. At this time, the limit pin 6 is stuck between the connecting plate 101 and the retaining ring 5, which can prevent the door from closing automatically. When the door needs to be closed, the retaining ring 5 is lifted upward by the foot surface of the single foot, so that the limit pin 6 is free from the restriction of the retaining ring 5, and the door can be closed.

[0032] B. Figure 1 As shown, the stopper includes a mounting plate 7 for mounting on the door and a stopper ring 8 fixed on the mounting plate 7. In this embodiment, the stopper ring 8 is a U-shaped ring with both ends fixed on the mounting plate 7. In actual use, it is fixed to the bottom of the door by welding the mounting plate 7. The structure is as shown in FIG. Figure 4 When the door is opened, the front end of the limit ring 8 applies an inward thrust to the retaining ring 5, causing the retaining ring 5 to roll upward so that the limit ring 8 moves to the bottom of the retaining ring 5. The process can be referred to Figure 3 , then the retaining ring 5 falls back under the action of gravity, and the bottom extends into the limiting ring 8, so that the limiting ring 8 cannot be separated from the limiting pile 1, thereby preventing the door from closing automatically; when the door needs to be closed, the retaining ring 5 is lifted upward with one foot, so that the retaining ring 5 is separated from the limiting ring 8, and the door can be closed.

[0033] It should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art may still modify the technical solutions described in the above embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
