Description

Technical Field

[0001] This utility model belongs to the technical field of security and anti-theft, specifically a convenient door stop. Background Technology

[0002] Currently, to enhance door security, people often install a movable door chain on the door and frame. Once engaged, the door can only open to a certain angle, preventing unauthorized entry. However, current door chains almost universally suffer from the following problems: 1. Door chains are composed of multiple linked links, resulting in limited strength. A significant impact can easily damage the chain, making its security level low. 2. Since most doors are now made of wood, the fixing pins used to secure the door chain often come loose or fail to hold properly, rendering the chain merely decorative and ineffective in preventing forced entry. This is especially true in hotels and guesthouses, where many door chains are damaged and unusable, significantly increasing the security risk for guests. 3. Current door chains have limited applicability; they can only be used on wooden doors. If the door is made of steel, the chain cannot be securely fastened.

Detailed Implementation

[0022] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model discloses a convenient door stopper, including a connecting plate 1 for inserting into the gap between the door frame and the door, and a blocking block 3 fitted and sliding on the connecting plate 1. The connecting plate 1 has a blocking hole 5 on its side wall, and the blocking block 3 has a locking hole 9 on each side wall that is adapted to the size of the blocking hole 5. It also includes a locking member 4 for inserting into the locking hole 9 and the blocking hole 5.

[0024] This embodiment includes a connecting plate 1, a blocking block 3, and a locking member 4. The blocking block 3 slides on the connecting plate 1. The connecting plate 1 has evenly distributed blocking holes 5. The blocking block 3 has locking holes 9 corresponding to the blocking holes 5. The locking member 4 passes through the locking hole 9 and is limited within the blocking hole 5 to lock and fix the blocking block 3. After the connecting plate 1 is inserted into the gap between the door frame and the door, it prevents the blocking block from moving, thus preventing the door from being opened and improving the safety of the residents.

[0025] In a preferred embodiment, the locking member 4 includes a locking body 41 that is arc-shaped and inserted into the locking hole 9 and the blocking hole 5, and an arc-shaped connecting part 42 that extends along the arc-shaped outer wall of the locking body 41. In this embodiment, by using the locking body 41 to simultaneously insert into the locking hole 9 and the blocking hole 5, the blocking block 3 is locked and limited to prevent it from moving, thereby achieving a door-blocking effect.

[0026] In a preferred embodiment, the blocking block 3 is provided with a connecting hole 8 near the top to accommodate the sliding of the arc-shaped connecting part 42. In this embodiment, this structure is advantageous for connecting the locking member 4 to the blocking block 3, which facilitates operation.

[0027] In a preferred embodiment, the end of the arc-shaped connecting portion 42 is provided with a front protrusion 43 extending out of the inner wall of the arc-shaped connecting portion 42, and a locking protrusion 44 extending out of the inner wall of the arc-shaped connecting portion is provided near the end of the arc-shaped connecting portion. An anti-retraction groove 45 for engaging with the connecting hole 8 is provided between the front protrusion and the locking protrusion. In this embodiment, this structure allows the locking member 4 to deflect and move between the connecting hole 8 and the locking hole 9. When moving upward along the connecting hole 8, the locking body 41 disengages from the locking hole 9. When moving downward along the connecting hole 8, the locking body 41 slides into the locking hole 9. The anti-retraction groove 45 facilitates locking and anti-retraction after the locking body 41 slides into the locking hole 9. Only after the arc-shaped connecting portion 42 is lifted and moved out of the anti-retraction groove 45 can the locking body 41 deflect and move upward and downward along the connecting hole.
