Description

Technical Field

[0001] The invention relates to the technical field of building doors and windows, and in particular to a quick-install transmission lock box for an inner horizontal opening and lower hanging system. Background Art

[0002] The transmission lock box used in the underslung system commonly used in the current construction field needs to be installed with screws during the installation process, which is labor-intensive and time-consuming. The lock box is installed with a vane, and the vane is exposed and unsightly. The market prefers fashionable and simple designs with large glass and narrow-sided windows. Narrow-sided windows reduce the installation space of the transmission lock box, and the transmission distance of the traditional underslung system limits the minimum size of the lock box gear, resulting in a large size of the lock box. As a result, the transmission lock boxes on the market cannot be adapted to this type of material.

[0003] To this end, the present application designs a quick-install transmission lock box for an inner horizontal opening lower suspension system and solves the above-mentioned problems. Summary of the invention

[0004] In order to make up for the deficiencies in the prior art, the present invention provides a quick-install transmission lock box for an inner horizontal opening lower suspension system.

[0005] A quick-install transmission lock box for an inner horizontal opening lower suspension system, comprising a housing A and a housing B, characterized in that: The two ends of the shell A are provided with limit grooves, the inner wall of the limit groove is provided with at least two limit ribs, and the middle position of the limit groove is provided with a semicircular limit hole; the middle position of the inner cavity of the shell A is provided with an installation groove, an elastic device is installed in the installation groove, and a positioning steel ball is provided on the top of the elastic device; the shell A is installed with a gear, the gear meshes with a transmission rack, and a transmission tooth of the meshing gear is provided on the middle side of the rack; the two ends of the shell B are provided with limit grooves, the inner wall of the limit groove is provided with at least two limit ribs, and the middle position of the limit groove is provided with a semicircular limit hole; after the shell B and the shell A are assembled, the two groups of semicircular limit holes form a complete circular limit hole, a fixing piece is provided at the complete circular limit hole, a circular boss is provided at the center position of the fixing piece, and a hexagonal wrench hole is provided at the center of the circular boss; the shell A is provided with a slider mounting hole, and the slider is placed in the slider mounting hole.

[0006] Furthermore, in order to better realize the present invention, the gear adopts a gradual tooth height, and the gear has a middle tooth whose tooth height gradually decreases toward the edge tooth; the transmission teeth of the rack adopt a gradual tooth height, and the transmission tooth height gradually increases from the middle part to both ends. The gear and the transmission tooth shape complement each other in meshing transmission, and the edge tooth height of the gear is reduced, which can effectively reduce the volume of the lock box and improve the adaptability range of the lock box.

[0007] Furthermore, in order to better realize the present invention, a positioning groove is set in the middle of the rack away from the transmission tooth side. Under the action of the elastic device, the positioning steel ball elastically squeezes the rack to reduce the shaking of the rack. The rack slides to the middle position of the lock box, and the positioning steel ball presses against the positioning groove to realize the positioning function.

[0008] Furthermore, in order to better implement the present invention, at least one slot is set on the side of the slider, and an anti-slip strip is provided in the slot. The slider is inserted into the slider mounting hole of the outer shell armor, and the anti-slip strip forms elastic extrusion with the inner wall of the outer shell armor to prevent the slider from falling off.

[0009] The beneficial effects of the present invention are: The invention has a simple structure, and under the condition of the same edge-to-center distance, the lock box of the invention has a smaller volume, is convenient to install, has strong practicality, has good structural strength, and is widely applicable.
