Description

Technical Field

[0001] This utility model relates to the field of handles, and more particularly to a handle with a keyhole opening and closing plate. Background Technology

[0002] Chinese Patent No. CN221742306U discloses a handle with a support structure, including a base and a handle disposed on the upper end of the base. The base is provided with a keyhole for inserting a key, and an opening and closing component is provided on the keyhole for opening and closing the keyhole. The opening and closing component includes an opening and closing plate disposed on the keyhole that can be flipped on the keyhole, and blocking components disposed on both sides of the keyhole to reduce the probability of the opening and closing plate automatically flipping. The blocking component includes a storage groove disposed on the base, a blocking block that is telescopically disposed in the storage groove, an elastic member disposed between the blocking block and the storage groove to drive the blocking block to extend out of the storage groove, and an inlet component to drive the blocking block to retract into the storage groove. The inlet component includes an inlet ramp disposed at the end of the blocking block away from the storage groove.

[0003] In the above structure, when the opening and closing plate is rotated, the opening and closing plate will press against the guide slope on the blocking block, thereby driving the blocking block to retract into the storage groove. When the blocking block retracts into the storage groove, the elastic element set between the blocking block and the storage groove will be compressed. At this time, the elastic element will apply a reaction force to the blocking block, which makes it more difficult for the opening and closing plate to press the blocking block to retract. Utility Model Content

[0004] This invention addresses the drawback of existing technologies where, when the blocking block rotates and is squeezed to retract, the elastic element between the blocking block and the storage groove exerts a reaction force on the blocking block, making it difficult for the opening and closing plate to squeeze the blocking block to retract. The invention provides a handle with a keyhole opening and closing plate that makes opening the keyhole effortless.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] A handle with a keyhole opening and closing plate includes a handle body, a keyhole provided on the handle body, and an opening and closing plate provided on the handle body for opening and closing the keyhole. One end of the opening and closing plate is hinged to the handle body. A first limiting component is provided between the opening and closing plate and the handle body to limit the position of the opening and closing plate when the keyhole is closed. The first limiting component includes a through hole provided on the opening and closing plate, a limiting hole provided on the handle body at a position opposite to the through hole, and a limiting pin that passes through the through hole and is inserted into the limiting hole to limit the flipping of the opening and closing plate.

[0007] With the above solution, the limiting pin can pass through the through hole on the opening and closing plate and insert into the limiting hole on the handle body when the keyhole is closed, thereby limiting the position of the opening and closing plate and keeping it in the closed keyhole state. When the keyhole needs to be opened, simply pull the limiting pin out of the limiting hole and flip the opening and closing plate, making it more convenient and effortless to open the keyhole.

[0008] Preferably, a second limiting component is provided on the handle body for the insertion of a limiting pin and for limiting the position of the opening and closing plate when the opening and closing plate is flipped to open the keyhole.

[0009] Preferably, the second limiting component includes a plug hole on the handle body that faces the through hole when the opening and closing plate is flipped to the open keyhole state and is for the insertion of the limiting pin.

[0010] With the above solution, the insertion hole on the handle body, which is opposite to the through hole when the opening and closing plate is flipped to the open keyhole state, allows the insertion of the limiting pin when the opening and closing plate is flipped to the open keyhole state, thereby limiting the position of the opening and closing plate and keeping the opening and closing plate in the open keyhole state, so that the operator can easily insert the key into the keyhole to open the door lock.

[0011] Preferably, the limiting pin is provided with a pull block that allows the operator to pull the limiting pin through the hole, and a detachable component is provided between the pull block and the limiting pin to enable disassembly and assembly between the two.

[0012] Using the above solution, the pull block set on the limit pin can facilitate the operator to pull the limit pin out of the through hole, and facilitate the limit pin to disengage from the limit hole or the insertion hole, so that the opening and closing plate can be flipped on the handle body. The detachable part set between the pull block and the limit pin can remove the pull block from the limit pin when the limit pin is inserted into the limit hole or the insertion hole.

[0013] Preferably, the detachable component includes a first magnet embedded in the traction block and a second magnet that can be attracted to the first magnet and is provided on the limiting pin. The second magnet is provided in two pieces and is respectively embedded at both ends of the limiting pin.

[0014] Using the above scheme, the first magnet set on the pulling block can attract the second magnet on the limiting pin when the limiting pin needs to be pulled out from the limiting hole or the insertion hole, thereby realizing the connection between the pulling block and the limiting pin, which makes it convenient for the operator to pull the limiting pin inserted into the limiting hole or the insertion hole.

[0015] Preferably, the handle body or the opening and closing plate is provided with a storage groove for storing the pull block removed from the limiting pin.

[0016] With the above solution, the storage slot provided on the handle body or the opening and closing plate can be used to insert the pull block when it is removed from the limiting pin, thereby realizing the storage of the pull block.

[0017] Preferably, the end of the pulling block away from the first magnet is hinged with a pulling ring that facilitates the operator to remove the pulling block from the storage slot.

[0018] Using the above scheme, the traction ring located at the end of the traction block away from the first magnet makes it easy for the operator to remove the traction ring stored in the storage slot from the storage slot.

[0019] Preferably, the limiting pin has a certain degree of damping when sliding within the perforation.

[0020] By adopting the above solution, a certain damping is set between the limiting pin and the through hole, which can improve the stability of the limiting pin when it passes through the through hole and is inserted into the limiting hole or the insertion hole, and reduce the probability of the limiting pin automatically coming out of the limiting hole or the insertion hole.

[0021] This utility model has significant technical effects due to the adoption of the above technical solutions: the limiting pin can pass through the through hole on the opening and closing plate and insert into the limiting hole on the handle body when the keyhole is closed, thereby limiting the position of the opening and closing plate and keeping the opening and closing plate in the closed keyhole state. When the keyhole needs to be opened, it is only necessary to pull out the limiting pin from the limiting hole and flip the opening and closing plate, thereby making the opening of the keyhole more convenient and labor-saving.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0034] Example

[0035] A handle with a keyhole opening and closing plate, reference Figures 1-3 , Figures 7-10 The device includes a handle body 1, a keyhole 2 provided on the handle body 1, and an opening / closing plate 3 provided on the handle body 1 for opening and closing the keyhole 2. One end of the opening / closing plate 3 is hinged to the handle body 1. A first limiting component is provided between the opening / closing plate 3 and the handle body 1 to limit the position of the opening / closing plate 3 when the keyhole 2 is closed. The first limiting component includes a through hole 4 provided on the opening / closing plate 3, a limiting hole 5 provided on the handle body 1 at a position opposite to the through hole 4, and a limiting pin 6 that passes through the through hole 4 and is inserted into the limiting hole 5 to limit the flipping of the opening / closing plate 3. The limiting pin 6 slides in the through hole 4 with a certain amount of damping.

[0036] refer to Figures 1-6 The handle body 1 is provided with a second limiting component that allows the limiting pin 6 to be inserted and limits the position of the opening and closing plate 3 when the opening and closing plate 3 is flipped to open the key hole 2. The second limiting component includes a plug hole 7 provided on the handle body 1 that is opposite to the through hole 4 and allows the limiting pin 6 to be inserted when the opening and closing plate 3 is flipped to open the key hole 2.

[0037] The limiting pin 6 is provided with a pulling block 8 to facilitate the operator to pull the limiting pin 6 in the through hole 4. A detachable component is provided between the pulling block 8 and the limiting pin 6 to realize the assembly and disassembly of the two. The detachable component includes a first magnet 9 embedded in the pulling block 8 and a second magnet 10 that can be attracted to the first magnet 9 on the limiting pin 6. Two second magnets 10 are provided and are respectively embedded at both ends of the limiting pin 6.

[0038] refer to Figures 1-5 ,refer to Figures 7-9 The handle body 1 or the opening and closing plate 3 is provided with a storage groove 11 for storing the pull block 8 removed from the limiting pin 6. In this embodiment, the storage groove 11 is provided on the handle body 1, and the end of the pull block 8 away from the first magnet 9 is hinged with a pull ring 12 to facilitate the operator to take the pull block 8 out of the storage groove 11.

[0039] The specific opening and closing process of keyhole 2 is as follows: When keyhole 2 needs to be opened, firstly, the pulling block 8 is pulled out of the storage slot 11 by the pulling ring 12. Then, the pulling block 8 is installed on the limiting pin 6, so that the first magnet 9 on the pulling block 8 and the second magnet 10 at one end of the limiting pin 6 attract each other. At this time, the pulling block 8 can be pulled to pull the limiting pin 6 out of the limiting hole 5. When the limiting pin 6 is pulled out of the limiting hole 5, the opening and closing plate 3 can be flipped, thereby opening keyhole 2. When the opening and closing plate 3 is flipped so that the through hole 4 and the insertion hole 7 are aligned, one end of the limiting pin 6 can be inserted into the insertion hole 7 through the through hole 4, thereby limiting the position of the opening and closing plate 3 and reducing the impact of the opening and closing plate 3 on the subsequent operator to open the door lock. Finally, First, remove the pull block 8 from the limiting pin 6 and install it into the storage slot 11 for storage. When the keyhole 2 needs to be closed, first, pull the pull block 8 out of the storage slot 11 using the pull ring 12, then install the pull block 8 onto the limiting pin 6. After that, pull the pull block 8 so that it drives the limiting pin 6 to disengage from the insertion hole 7. At this time, the opening and closing plate 3 can rotate on the handle body 1. When the opening and closing plate 3 rotates to the closed handle body 1 state, the limiting pin 6 can be inserted into the limiting hole 5 through the through hole 4. At this time, the limiting pin 6 will limit the position of the opening and closing plate 3, keeping the opening and closing plate 3 in the closed keyhole 2 state. Finally, remove the pull block 8 from the limiting pin 6 and install it into the storage slot 11 for storage.
