Description

Technical Field

[0001] This utility model relates to the field of handles, and more particularly to an outward-opening handle. Background Technology

[0002] An outward-opening handle is a device specifically designed for operating outward-opening windows. Its purpose is to facilitate users in opening and closing windows and to ensure that windows can be securely locked.

[0003] Chinese Patent No. CN221838118U discloses a plastic sliding cover structure for a handle base, including a base, a rotating shaft disposed in the base, and a handle that can drive the rotating shaft to rotate. The base has a countersunk hole, in which a screw for fixing the base to a window is disposed. The base has a cover component for covering the countersunk hole. The cover component includes a sliding cover that is slidably disposed on the base. Anti-detachment components are respectively disposed between the two inner walls of the sliding cover and the two side walls of the base to limit the sliding cover when it is fully slid in. The anti-detachment components include a first limiting component for limiting the vertical movement of the sliding cover and a second limiting component for limiting the horizontal movement of the sliding cover. The first limiting component includes a limiting plate disposed on the inner walls of the two sides of the sliding cover and a limiting groove disposed on the base with the same size as the limiting plate. The second limiting component includes a locking block protruding on the limiting groove and a locking groove disposed on the limiting plate for partial insertion of the locking block.

[0004] In the above structure, the limiting plates on both sides of the sliding cover can restrict the vertical movement of the sliding cover when it is installed on the base. The slots on the limiting plates allow the protrusions on the limiting slots to be partially inserted when the sliding cover is installed on the base, thereby restricting the horizontal movement of the sliding cover. However, when the sliding cover needs to be removed from the base, it is necessary to pull the sliding cover to make the slots and the blocks press against each other, thereby causing the limiting plates to deform the sliding cover and the blocks to come out of the slots. At this time, the sliding cover can be removed from the base. However, it is very difficult to pull the sliding cover to make the limiting plates on the sliding cover deform the sliding cover. Utility Model Content

[0005] This invention addresses the drawback of existing technologies where pulling a sliding cover requires considerable effort, causing the limiting plate on the cover to deform locally. It provides an outward-opening handle that makes disassembling the sliding cover easier and more convenient.

[0006] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0007] An outward-opening handle includes a handle body and a sliding cover disposed on the handle body. A vertical limiting component and a horizontal limiting component are disposed between the sliding cover and the handle body to restrict the vertical movement of the sliding cover when it is closed onto a countersunk hole. The horizontal limiting component includes slots disposed on the inner walls of both sides of the sliding cover and blocks disposed on both sides of the handle body that are inserted into the slots to restrict the horizontal movement of the sliding cover when it is closed onto the countersunk hole. The blocks are telescopically mounted on the handle body via a telescopic structure. Pushing components are disposed on both sides of the sliding cover to drive the blocks out of the slots when the sliding cover needs to be removed from the handle body. The pushing components include sliding grooves disposed on both sides of the sliding cover and pushing blocks disposed within the sliding grooves that can push the blocks out of the grooves when the blocks are pushed into the sliding grooves. The two sliding grooves are respectively connected to their corresponding slots.

[0008] Using the above solution, the pushing block set in the sliding groove can push the locking block out of the locking groove on the sliding cover when the sliding cover needs to be removed from the handle body. After the locking block is removed from the locking groove, the sliding cover can be directly removed from the handle body by simply sliding the sliding cover horizontally, thus making the removal of the sliding cover more convenient and labor-saving.

[0009] Preferably, the push block extends partially outside the sliding groove, and a position limiting component is provided at the point where the push block extends outside the sliding groove to prevent the push block from being completely retracted into the sliding groove.

[0010] Preferably, the position limiting component includes a blocking plate sleeved on the part of the push block extending out of the sliding groove, wherein the surface of the blocking plate abuts against the outer wall of the sliding cover when the push block extends into the sliding groove.

[0011] Using the above solution, the blocking plate fitted outside the sliding groove of the push block can abut against the outer wall of the sliding cover when the push block moves into the sliding groove, thereby limiting the push block from going deeper into the sliding groove, reducing the probability of the push block being completely retracted into the sliding groove, and making it more convenient for the operator to push the push block.

[0012] Preferably, an anti-detachment component is provided between the sliding groove and the pushing block to prevent the pushing block from detaching from the sliding groove.

[0013] Preferably, the anti-detachment component includes a mounting groove recessed on the side wall of the push block, an elastic hook provided on the side wall of the mounting groove away from the bottom of the groove, and a locking groove provided on the inner wall of the sliding groove, wherein the end of the elastic hook that moves therein and is away from the handle body can engage with the elastic hook.

[0014] Using the above scheme, the elastic hook on the side wall of the push block can undergo elastic deformation due to the pressure of the inner wall of the sliding groove when the push block is inserted into the sliding groove, so that the push block can be inserted into the sliding groove. When the push block is inserted into the sliding groove and the elastic hook moves into the engagement groove, the elastic hook will return to its original position. At this time, the elastic hook can slide in the engagement groove. When the elastic hook and the end of the engagement groove engage with each other, the elastic hook will limit the movement of the push block, thereby preventing the push block from coming out of the sliding groove.

[0015] Preferably, the telescopic structure includes a storage groove on the handle body for storing the card block when the card block retracts, an inlet component on the card block for automatically retracting the card block into the storage groove when the sliding cover is installed on the handle body, and a reset component for causing the card block to extend partially out of the storage groove in normal operation and for resetting the card block after it retracts.

[0016] Using the above solution, the storage slot on the handle body can store the locking block when the locking block retracts, so that the sliding cover can slide horizontally on the handle body, realizing the disassembly of the sliding cover and the handle body. The guide component on the locking block can drive the locking block to automatically retract into the storage slot when the sliding cover is installed on the handle body, so that the sliding cover can be installed onto the handle body more effortlessly. The reset component between the storage slot and the locking block can drive the locking block retracted into the storage slot to reset and partially extend out of the storage slot and maintain the state of partially extending out of the storage slot.

[0017] Preferably, the inlet component includes an inlet ramp provided at the end of the card block away from the bottom of the storage slot.

[0018] Using the above solution, the guide slope set at the end of the card block away from the bottom of the storage slot can abut against the surface of the sliding cover when the sliding cover is installed on the handle body. As the sliding cover continues to move horizontally, the sliding cover will squeeze the guide slope, thereby causing the guide slope to drive the card block into the storage slot.

[0019] Preferably, the reset component includes a reset spring disposed between the storage slot and the locking block, with both ends of the reset spring connected to the bottom of the storage slot and the end of the locking block near the bottom of the storage slot, respectively.

[0020] Using the above solution, the reset spring set between the card block and the storage slot can push the card block to a state where it is partially extended out of the storage slot under normal conditions. At the same time, when the card block is retracted into the storage slot and the card block is aligned with the card slot, the reset spring will push the card block to move out of the storage slot. At this time, the card block will automatically insert into the card slot, thereby limiting the horizontal movement of the sliding cover.

[0021] This utility model has significant technical effects due to the adoption of the above technical solutions: the pushing block set in the sliding groove can push the locking block to disengage from the locking groove on the sliding cover when the sliding cover needs to be removed from the handle body. After the locking block disengages from the locking groove, the sliding cover can be directly removed from the handle body by simply sliding the sliding cover horizontally, thus making the disassembly of the sliding cover more convenient and labor-saving.
