Description

Technical Field

[0001] This utility model relates to the field of door stop technology, specifically a novel outward-opening door stop. Background Technology

[0002] Outward-opening door stoppers are a common device used for home protection and burglary prevention, especially suitable for women living alone. Most existing outward-opening door stoppers use mechanical principles or locking mechanisms to effectively prevent forced entry and burglary. Outward-opening door stoppers are suitable for doors that open outwards; because the inner handle of the door lock is locked, the outward-opening door cannot be pulled open from the outside.

[0003] Most outward-opening door stoppers on the market currently use adhesive or quick-release latches for partial locking. Their structure has poor stability and is prone to failure under violent damage, thus rendering the outward-opening door stopper ineffective in preventing the outward-opening door from being forcibly opened. In addition, existing outward-opening door stoppers are cumbersome to install and remove and are prone to wear and tear on the outward-opening door. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of outward-opening door stopper, which is convenient to install and disassemble, has high stability, and is not prone to causing wear and tear on outward-opening doors.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a novel outward-opening door stopper, including a limiting support frame and a locking pin. The limiting support frame is used to press against the horizontal brace inside the wall door frame. The locking pin is detachably installed on the limiting support frame. The locking pin is used to block and limit the outward movement of the door handle on the outward-opening door.

[0006] Preferably, the limiting support frame has a rectangular structure.

[0007] Furthermore, the limiting support frame includes a main frame and a telescopic frame, with the telescopic frame slidably fitted onto one end of the main frame.

[0008] Furthermore, a pressing bolt for pressing and positioning the telescopic frame is provided on the main frame.

[0009] Preferably, a jacking mechanism is provided between the main frame and the telescopic frame, and the jacking mechanism always applies a thrust to the telescopic frame away from the main frame.

[0010] Preferably, the jacking mechanism is a gas spring support rod, one end of which is hinged to one end of the main frame, and the other end of which is hinged to one side of the telescopic frame.

[0011] Furthermore, both the main frame and the telescopic frame are U-shaped.

[0012] Furthermore, two first through holes are vertically provided on the end of the main frame away from the telescopic frame, and the locking pin can be vertically inserted into the two first through holes.

[0013] Furthermore, two first support rods distributed to the left and right are provided on the inner side of the end of the main frame away from the telescopic frame, and a second through hole is provided horizontally on each of the two first support rods, and the locking pin can be horizontally inserted into the two second through holes.

[0014] Furthermore, the locking pin is a tongue-type pin.

[0015] The beneficial effects of this utility model are as follows: The utility model has a simple structure and is convenient to manufacture; both the main frame and the telescopic frame are rectangular frame structures, allowing them to fit flush with the outward-opening door frame. This prevents the locking pin from rotating when the door handle pulls the locking pin. Simultaneously, the limiting effect of the outward-opening door frame provides strong outward resistance, further enhancing the locking effect of the locking pin on the door handle and effectively preventing the outward-opening door from being forcibly pulled open. The main frame and telescopic frame are adjustable, allowing this utility model to be used on wall frames of different widths. The top-pressing bolts and pushing mechanism effectively prevent the support limiting frame from detaching from the wall frame, thus improving the reliability of this utility model. The locking pin is installed on the main frame using a plug-in method, making installation and disassembly convenient. During application, the locking pin does not contact the outward-opening door, and the ends of the main frame and telescopic frame only contact the side walls of the outward-opening door frame, making this utility model less prone to wear on the outward-opening door.

Detailed Implementation

[0024] The following will describe specific embodiments and appendices. Figure 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some preferred embodiments of this utility model, and not all embodiments. Those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0025] This utility model provides a novel outward-opening door stop (such as...). Figure 1 As shown, it includes a limiting support frame 1 and a locking pin 2. The limiting support frame 1 is used to press the horizontal brace against the wall door frame 5. The locking pin 2 is detachably installed on the limiting support frame 1. The locking pin 2 is used to block and limit the outward movement of the door handle on the outward-opening door 6. In practical applications, when the limiting support frame 1 is pressed against the wall door frame 5, the limiting support frame 1 is positioned, and the outward opening door frame 61 has an outward movement limiting effect on the limiting support frame 1. When the outward opening door is pulled outward with force, the door handle is blocked by the locking pin 2, and the locking pin 2 transmits the force to the limiting support frame 1. The limiting support frame 1 is blocked by the outward opening door frame 61, thereby achieving the outward opening blocking of the outward opening door 6. The installation and removal of the limiting support frame 1 on the wall door frame 5 are convenient. At the same time, the installation and removal of the locking pin 2 on the limiting support frame 1 are also convenient, thereby improving the installation convenience of this utility model. Moreover, the limiting support frame 1 uses the outward opening door frame 61 to achieve blocking and limiting, and its blocking stability is high. Based on the high connection strength between the door handle and the outward opening door 6 and the high structural strength of the limiting support frame 1 itself, this utility model can effectively achieve strong outward pulling blocking of the outward opening door 6, thereby improving home security and anti-theft effect.

[0026] Based on the above embodiments, in order to effectively prevent the limiting support frame 1 from rotating when it is pulled, the limiting support frame 1 is made into a rectangular structure. When the limiting support frame 1 is rectangular, the door handle of the outward opening door 6 is located inside the limiting support frame 1. When the door handle of the outward opening door 6 is pulled, the locking pin 2 will not apply a rotational torque to the limiting support frame 1, thereby effectively preventing the limiting support frame 1 from rotating.

[0027] Based on the above embodiments, to facilitate the installation and fixation of the limiting support frame 1 on wall frames 5 of different widths, the limiting support frame 1 includes a main frame 11 and a telescopic frame 12. The telescopic frame 12 is slidably fitted onto one end of the main frame 11. By changing the position of the telescopic frame 12 on the main frame 11, the length of the limiting support frame 1 can be adjusted. Furthermore, to facilitate the positioning of the telescopic frame 12 on the main frame 11 and ensure the stable horizontal support of the limiting support frame 1 on the wall frame 5, a pressing bolt 3 is provided on the main frame 11 for pressing and positioning the telescopic frame 12. After adjusting the position of the telescopic frame 12 on the main frame 11, the pressing bolt 3 is tightened to fix the telescopic frame 12 on the main frame 11. When it is necessary to disassemble the limiting support frame 1, the pressing bolt 3 is loosened, and then the telescopic frame 12 is retracted to a certain extent, so that the limiting support frame 1 can be easily removed from the wall frame 5.

[0028] Based on the above embodiments, to further improve the stability of the lateral bracing of the limiting support frame 1 within the wall frame 5, a pushing mechanism is provided between the main frame 11 and the telescopic frame 12. This pushing mechanism consistently applies a pushing force to the telescopic frame 12 away from the main frame 11. Specifically, the pushing mechanism can be a gas spring support rod 4, a regular spring, etc. When the pushing mechanism is a gas spring support rod 4, one end of the gas spring support rod 4 is hinged to one end of the main frame 11, and the other end of the gas spring support rod 4 is connected to the telescopic frame 12. The gas spring support rod 4 is a mature technology product on the market, and its specific structure and working principle will not be described in detail here. The gas spring support rod 4 can extend and retract to a certain extent, and thus the telescopic frame 12 can be continuously pushed by the gas spring support rod 4. Even after the top bolt 3 loses its locking function, the top pressure of the telescopic frame 12 by the gas spring support rod 4 can also achieve stable support between the main frame 11 and the telescopic frame 12 and the wall frame 5, thereby improving the application reliability of this utility model.

[0029] To facilitate the processing and manufacturing of the main frame 11 and the telescopic frame 12, both the main frame 11 and the telescopic frame 12 are U-shaped, and a reinforcing rod is provided inside the main frame 11.

[0030] In practical applications, the inner door handles on outward-opening doors 6 are generally divided into horizontally placed L-shaped door handles 62 and vertically placed L-shaped door handles 63. To facilitate the outward pulling limit of the horizontally placed L-shaped door handle 62 using this utility model, two first through holes are vertically provided on the end of the main frame 11 away from the telescopic frame 12. The locking pin 2 can be vertically inserted into the two first through holes. In practical applications, when this embodiment is required, the limiting support frame 1 is first horizontally fixed to the wall door frame 5. The corresponding side wall of the limiting support frame 1 is aligned with the outward-opening door frame 61. After the installation and positioning of the limiting support frame 1 is completed, the horizontally placed L-shaped door handle 62 is located inside the main frame 11. Then, the locking pin 2 is directly inserted into the first through hole. At this time, the locking pin 2 is located between the horizontally placed L-shaped door handle 62 and the inner side wall of the outward-opening door 6. Thus, when the outward-opening door 6 is pulled from the outside, the locking pin 2 blocks the outward movement of the horizontally placed L-shaped door handle 62, thereby blocking the outward opening of the outward-opening door 6.

[0031] To facilitate the outward pulling limit of the vertically placed L-shaped door handle 63 using this utility model, two left-right distributed first support rods 111 are provided on the inner side of the end of the main frame 11 away from the telescopic frame 12. A second through hole is horizontally provided on each of the two first support rods 111, and the locking pin 2 can be horizontally inserted into the two second through holes. In practical applications, when this embodiment is required, the limiting support frame 1 is first horizontally fixed to the corresponding position on the wall door frame 5, thus limiting the movement. The corresponding side wall of the support frame 1 fits against the outward-opening door frame 61. After the installation and positioning of the limiting support frame 1 is completed, the vertically placed L-shaped door handle 63 is located between the two first support rods 111. Then, the locking pin 2 is directly inserted into the second through hole. At this time, the locking pin 2 is located between the vertically placed L-shaped door handle 63 and the inner side wall of the outward-opening door 6. Thus, when the outward-opening door 6 is pulled from the outside, the locking pin 2 blocks the outward movement of the vertically placed L-shaped door handle 63, thereby blocking the outward opening of the outward-opening door 6.

[0032] In order to effectively prevent the locking pin 2 from falling off the limiting support frame 1 during the handling or use of this utility model, the locking pin 2 is made into a tongue-type pin, a locking ring pin, or a locking bead pin. The tongue-type pin, the locking ring pin, or the locking bead pin are known mature technology products in the prior art, so the detailed structure and usage of the tongue-type pin will not be described in detail.

[0033] In this utility model, "upper", "lower", "front", "back", "left", and "right" are all relative positions used to facilitate the description of positional relationships, and therefore cannot be understood as absolute positions as limitations on the scope of protection.

[0034] Except for the technical features described in the specification, all other technologies are known to those skilled in the art.

[0035] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. For those skilled in the art, several improvements and modifications can be made without departing from the concept of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
