Description

Technical Field

[0001] The utility model relates to the field of handles, in particular to a handle with a screw cap. Background Art

[0002] The handle is an important component on the window, which includes a base installed on the window by screws, a rotating shaft arranged in the base, and a handle arranged above the base to drive the rotating shaft to rotate. The window is locked and unlocked by turning the handle to drive the rotating shaft to rotate.

[0003] A Chinese patent with announcement number CN219910358U discloses a self-locking handle base, including a base, a lock base and a pushing mechanism. The lock base is provided with a limiting groove, and the pushing mechanism is clamped in the limiting groove through a ball. The pushing mechanism includes a gear and a cover plate. The gear is rotatably embedded in the base, and installations are symmetrically provided on both sides of the gear. A button is embedded and slidably installed in the base. One end of the button is pressed against the base by a first spring, and the other end extends from the base. The button is provided with a step for shifting the tooth portion of the gear, the top of the tooth of the gear is used to press the ball in the limiting groove, and the root of the tooth of the gear is used to engage the ball. The cover plate covers the gear, the button and the ball and is installed in the base.

[0004] After the above mechanism is installed as a whole, it is necessary to use screws or the like to screw into the window frame through the through holes on the base, so as to install the handle on the window frame. However, the screws installed on the handle will be exposed to the air for a long time, thereby reducing the service life of the screws. Utility Model Content

[0005] The utility model provides a handle with a screw cap to solve the problem that the handle is installed on the window frame by screws in the prior art, but the heads of the screws are exposed to the air for a long time after installation, thus reducing the service life of the screws.

[0006] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0007] A handle with a rotating cover comprises a base, a square shaft installed in the base and a handle arranged on the top of the base for driving the square shaft to rotate, wherein a plurality of countersunk holes for installing screws are arranged on the base, and an opening and closing component for opening and closing the countersunk holes on the base is arranged on the top of the base, the opening and closing component comprises a cover plate arranged on the top of the base, a avoidance hole for the cover plate to rotate on the top of the base is arranged on the cover plate, and a limiting component for limiting the cover plate when the cover plate is flipped to be parallel to the base is arranged between the cover plate and the base.

[0008] By adopting the above scheme, the countersunk hole on the base can be covered by the set cover plate when it is parallel to the base, thereby reducing dust and wind particles falling onto the screw in the countersunk hole and increasing the service life of the screw. When the user needs to turn the screw, the cover plate can be rotated to make it intersect with the base. At this time, the countersunk hole set on the base will be exposed, and the set limiting component can limit the cover plate when the cover plate is rotated to be parallel to the base, thereby preventing the cover plate from automatically flipping over and improving the sealing performance between the cover plate and the base.

[0009] Preferably, the limiting component comprises four mutually spliced ​​limiting plates arranged around the cover plate, and a limiting groove for partial insertion of the limiting plates is arranged on the upper surface of the base.

[0010] By adopting the above scheme, the limit plate can be inserted into the limit groove on the base when the cover is parallel to the base, thereby limiting the cover and preventing the cover from rotating. At the same time, when the limit plate is inserted into the limit groove, the sealing of the cover to the countersunk hole can be improved, thereby further improving the service life of the screws installed in the countersunk hole.

[0011] Preferably, there is a rotation space between the handle and the base for the cover plate and the limit plate to rotate therebetween, and the height of the rotation space is greater than or equal to the height of the cover plate plus the limit plate.

[0012] By adopting the above scheme, a rotating space is set between the handle and the base for the cover plate and the limit plate to rotate therebetween, so that when the cover plate drives the limit plate to disengage from the limit groove, the cover plate and the limit plate can rotate in the rotating space, thereby realizing the opening and closing of the countersunk hole on the base.

[0013] Preferably, a pressing component is provided between the handle and the base for pushing the cover plate down when the cover plate is rotated to be parallel to the base.

[0014] Preferably, the pressing component includes a slot arranged at the bottom of the handle, in which is an elastic member with one end abutting against the bottom surface of the slot and the other end abutting against the upper surface of the cover plate, and one end of the elastic member away from the plug-in bottom surface partially extends out of the slot.

[0015] By adopting the above scheme, the elastic member arranged in the slot can push the cover plate to move downward when the cover plate is rotated to be parallel to the base, so that the limit plate arranged under the cover plate is inserted into the limit groove on the base. When the countersunk hole on the base needs to be exposed, the cover plate can be moved upward first to make the limit plate under the cover plate completely disengage from the limit groove and overlap on the top of the base after rotation. When the cover plate rises, it will also put pressure on the elastic member in the slot to retract it; and when the countersunk hole needs to be closed, the cover plate needs to be rotated to be parallel to the base. When the cover plate is parallel to the base, the elastic member will recover, thereby pushing the cover plate to move downward, so that the limit plate on the cover plate is automatically inserted into the limit groove on the base.

[0016] Preferably, operating components are provided on the side walls on both sides of the base to facilitate the user to push the cover plate upwards to drive the limiting plate to separate from the limiting groove.

[0017] Preferably, the operating component includes operating grooves symmetrically arranged on the side walls of both sides of the base.

[0018] By adopting the above solution, the provided operating slot can facilitate the user to push the cover plate upward and rotate it to expose the countersunk hole on the base.

[0019] Due to the adoption of the above technical scheme, the utility model has significant technical effects: the cover plate can cover the countersunk hole on the base when it is parallel to the base, thereby reducing dust and wind particles falling onto the screw in the countersunk hole and improving the service life of the screw; when the user needs to turn the screw, the cover plate can be rotated to intersect with the base, and the countersunk hole set on the base will be exposed, and the limiting component can limit the cover plate when the cover plate is rotated to be parallel to the base, thereby preventing the cover plate from automatically flipping over and improving the sealing performance between the cover plate and the base.
