Description

Technical Field

[0001] The utility model relates to the technical field of movable door and window protection devices, in particular to a movable door and window opening blocker. Background Art

[0002] The sliding door and window limiter is a protective device used to control the opening degree of sliding doors and windows, so as to maintain indoor air circulation when the doors and windows are half-open and avoid danger caused by children's misoperation.

[0003] The traditional design of movable door and window limiters includes a base and a baffle hinged thereon, and a movable top plate is hinged on the base to drive the baffle to swing. In the initial state, the movable top plate is upright to limit the movement of the baffle and prevent the doors and windows from opening beyond a predetermined position. In order to open or close the doors and windows again, the movable top plate can be tilted to a flat state. This function is achieved by a driving mechanism. However, in practice, this design has defects: first, the current limiter operates the driving mechanism through buttons on both sides to flatten the top plate to release the limit. Many household appliances also use a similar side button design to unlock, which may induce children to operate incorrectly and cause safety risks. Secondly, in order to achieve automatic opening of the baffle, a common solution is to use a compressed spring between the baffle and the base, but this makes the structure complicated and the cost increased. Utility Model Content

[0004] The purpose of the utility model is to solve the potential safety hazards in the prior art and the technical problems of increased costs due to complex structures, and to provide a movable door and window stopper with a simplified structure, low cost and difficult for children to operate by mistake.

[0005] In order to solve the above problems, the utility model provides a movable door and window blocker, including a base and a swing baffle plate hinged to the base at one end, the base is provided with an open groove for accommodating the swing baffle plate, a movable top plate for driving the other end of the swing baffle plate to swing open is provided in the open groove, one end of the movable top plate is hinged to the base, a torsion spring for keeping the movable top plate in an upright state and a driving mechanism for tilting and swinging the movable top plate are provided between the movable top plate and the base, a slide groove is provided in the open groove, the driving mechanism includes a moving part arranged in the slide groove and an elastic part arranged at one end of the moving part, the other end of the moving part is provided with a driving part for driving the movable top plate to rotate around the axis, a notch connected to the slide groove is provided at one end of the swing baffle plate, a pulling part for driving the moving part to move in the direction of the elastic part is provided in the notch.

[0006] Compared with the prior art, the utility model is advantageous in that: the utility model adopts a design of a driving mechanism and a pulling component, and the pulling component is hidden in the notch at one end of the swing baffle. Compared with the existing structure of buttons on both sides of the base, it has stronger concealment, and the pulling component requires greater force to operate than the buttons, which can effectively prevent children from operating it incorrectly and greatly improves safety during use; secondly, the utility model can control the swing baffle to open automatically by means of a torsion spring for keeping the movable top plate in an upright state, thereby eliminating the compression spring added between the swing baffle and the base in the prior art, greatly simplifying the overall structure and saving manufacturing costs.

[0007] Specifically, a slot is provided at the other end of the moving component for inserting one end of the movable top plate, and the driving part includes a first inclined block and a second inclined block which are arranged in a matching manner. The first inclined block is formed by extending the outer groove edge of the slot toward the rotating end of the movable top plate, and the second inclined block is arranged at the rotating end of the movable top plate and is pressed and matched with the first inclined block. After the structure is applied, when in use, the movable top plate is driven to rotate around the axis by the moving component through the pressing and matching of the first inclined block and the second inclined block, thereby realizing the conversion process of the movable top plate from the upright state to the inclined state, which not only improves the convenience of operation, but also ensures the smoothness and stability of the conversion process.

[0008] Specifically, one end of the pull component is hinged to the base, one end of the moving component is provided with a limit groove, and one end of the pull component is provided with a limit protrusion corresponding to the limit groove. After applying this structure, the upper limit protrusion of the pull component and the upper limit groove of the moving component cooperate with each other to achieve precise control of the movement range of the pull component.

[0009] As an improvement, a mounting groove for accommodating an elastic component is provided on the base, the mounting groove is located in the opening groove, the elastic component is a compression spring arranged in the mounting groove, a channel connected to the slide groove is provided on the outside of the mounting groove, and an extrusion portion is provided at one end of the movable component, the extrusion portion is inserted into the channel and is extruded and matched with one end of the compression spring. After applying this structure, the rebound force provided by the compression spring can drive the first inclined block and the second inclined block to release the extrusion state, thereby allowing the movable top plate to remain in an upright state under the action of the rebound force of the torsion spring. At the same time, the cooperation of the extrusion portion and the compression spring can effectively prevent impact during operation and protect the internal structure from damage. In addition, by optimizing the design of the mounting groove and the slide groove, the integration and compactness of the overall structure are improved, which is conducive to reducing the product volume and saving space.

[0010] As an improvement, the elastic component is an arc-shaped spring piece integrally formed with one end of the moving component, the free end of the arc-shaped spring piece contacts the inner groove wall of the slide groove and there is a movable gap between the free end of the arc-shaped spring piece and one end of the moving component. After the structure is applied, the rebound force provided by the arc-shaped spring piece can drive the first inclined block and the second inclined block to release the squeezed state, thereby keeping the movable top plate in an upright state under the action of the rebound force of the torsion spring. At the same time, the arc-shaped spring piece is integrally formed at one end of the moving component, which not only makes the two have a stronger connection strength, but also does not require additional components to provide rebound force, thereby simplifying the structure and saving costs.

[0011] As an improvement, a fixed connection spring sheet is provided between the swing baffle and the base, one end of the fixed connection spring sheet is fixedly connected to the base, and a movable gap is provided between the other end of the fixed connection spring sheet and the base. After the structure is applied, the swing baffle can have a greater resilience through the fixed connection spring sheet to drive it to open automatically. At the same time, compared with the spring drive structure in the prior art, the fixed connection spring sheet has a simpler structure and can save costs.

[0012] As an improvement, a pair of decorative buttons are provided on both sides of the base. The provision of the decorative buttons can induce children to press the decorative buttons, thereby reducing the risk of children unlocking by pulling the components, and further enhancing the safety protection function of the blocking device when in use.
