Description

Technical Field

[0001] The utility model relates to the technical field of door and window accessories, and in particular to a door and window handle spring box which is easy to install. Background Art

[0002] Door and window handle lock boxes are hardware accessories used to install and fix door and window handles and locks. They are key components for door and window safety. The handle lock boxes protect the safety of residents by firmly locking doors and windows to prevent illegal opening. The handle lock boxes are suitable for a variety of different types of doors and windows, such as PVC and aluminum alloy doors and windows, and can be adapted to related accessories such as actuators and linkage rods.

[0003] Publication No.: CN103410379B discloses an aluminum alloy handle for doors and windows. It assembles a shaft sleeve and a handle seat together, inserts the handle into the hole of the shaft sleeve; puts a spring into a lining plate, then puts a ball into the hole of the spring, assembles it with the lining plate, and then puts it inside the handle seat, then assembles a gasket on the lining plate and the other side of the handle seat, puts a gear on the gasket, fixes the handle seat and the handle together with a cross recessed countersunk screw, then puts a shift fork into the handle seat to mesh with the gear, a mounting hole passing through the handle seat is provided on the upper surface of the handle seat, a threaded hole is provided on the lower surface of the handle seat, a bottom cover is buckled in the hole of the handle seat and can expose the mounting hole and the threaded hole, and a matching buckle cover is provided on the mounting hole.

[0004] The lining plate of the aluminum alloy handle for doors and windows does not have an installation structure that is convenient for the installation of springs and steel balls. During installation, the transmission gear and the spring box must be installed first, and then the spring and the steel ball must be installed in the storage groove of the spring box. This installation method is not convenient for the production of automated machinery to automatically install springs and steel balls in the lock box because the transmission gear has a large number of sizes and models. The springs and steel balls need to be installed manually, and the installation efficiency is low. Therefore, this technology still has a certain room for modification. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a door and window handle spring box which is easy to install in view of the deficiencies of the above-mentioned prior art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a door and window handle spring box that is easy to install, comprising a box body, a spring, and a steel ball. Storage grooves are provided at both ends of the box body, and the spring and the steel ball are abutted and installed in the storage grooves. A mounting portion for installing an external transmission gear is provided in the center of the box body, characterized in that: the storage groove comprises a first storage groove and a second storage groove, the first storage groove is provided on both sides of the mounting portion, the first storage groove is provided with a first through hole with a diameter smaller than the steel ball at one end facing the mounting portion, the steel ball abuts against the first through hole, the second storage groove is axially provided at both ends of the mounting portion, the second storage groove is provided with a second through hole at one end facing the mounting portion, the mounting portion is provided with a shielding member for shielding the second through hole, and the steel ball in the second storage groove abuts against the shielding member.

During production, the shielding strip can serve as the abutment part of the steel ball in the second storage groove, which is convenient for the installation of the steel ball and the spring during production. During installation, the connecting block and the shielding strip are removed by the pressing force of the rotating gear, so that the internal steel ball can abut against the small teeth of the transmission gear, thereby realizing the function of the door and window handle to emit mechanical sound.

[0012] The above-mentioned door and window handle spring box that is easy to install can be further configured as follows: a first baffle plate is arranged around the connecting groove, a second baffle plate is arranged around the side of the connecting hole away from the first baffle plate, the first receiving groove is fixedly connected to the box body through the bottom first baffle plate, the first through hole is arranged in the middle of the first baffle plate, the box body and the second baffle plate form an installation groove, the second receiving groove is axially arranged in the installation groove and fixedly connected to the second baffle plate, and the second through hole is arranged in the middle of the second baffle plate.

[0013] By adopting the above technical solution, the large teeth and small teeth of the connected rotating gear can be stably linked with the steel balls in the first receiving groove and the second receiving groove through the setting of the first baffle plate and the second baffle plate, and the position of the rotating gear will not be changed, making the product more stable. The first receiving groove and the second receiving groove are respectively arranged on the first baffle plate and the second baffle plate to make the structure more solid and compact.

[0014] The above-mentioned door and window handle spring box which is easy to install can be further configured as follows: the steel ball in the first receiving groove abuts against the first through hole, the steel ball is partially exposed from the first through hole, one end of the spring abuts against the inner wall of the first receiving groove and the other end abuts against the steel ball; the steel ball in the second receiving groove abuts against the shielding member, one end of the spring abuts against the inner wall of the second receiving groove and the other end abuts against the steel ball.

[0015] By adopting the above technical solution, the spring in the first storage groove and the second storage groove contacts the steel ball and the inner wall of the storage groove, and based on the elastic force of the steel ball, the steel ball is prompted to closely cooperate with the large and small teeth of the transmission gear, which can enable the steel ball to generate a rebound force when it is linked with the transmission gear, making the product function more stable.

[0016] The above-mentioned door and window handle spring box that is easy to install can be further configured as follows: the at least two first storage grooves are fixedly connected to the first baffle plate, and the first storage grooves are symmetrically arranged; the at least two second storage grooves are fixedly connected to the second baffle plate, and the second storage grooves are symmetrically arranged.

[0017] By adopting the above technical solution, at least two first receiving grooves and the second receiving grooves are fixedly connected to the first baffle plate and the second baffle plate, ensuring that the linkage between the steel ball and the transmission gear is more stable, and the first receiving groove and the second receiving groove are symmetrically arranged so that the linkage between the steel ball and the transmission gear will not produce force deviation and cause damage to the product.

[0018] The beneficial effects of the utility model: the shielding effect of the first through hole and the shielding member can effectively install the steel ball and the spring directly in the first receiving groove and the second receiving groove without installing the transmission gear first. The spring and the steel ball can be directly installed by automated equipment, which greatly improves the installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
