Description

Technical Field

[0001] This utility model relates to the field of door and window accessories technology, and in particular, to a door and window handle. Background Technology

[0002] Currently, as people's demands for quality of life continue to increase, the requirements for the design of door and window handles are also getting higher and higher. They not only need to have advantages such as small size, convenient installation, and simple and beautiful appearance, but also need to completely cover and hide the installation structure.

[0003] For example, Chinese utility model patent CN204715890U provides an adjustable square-axis window handle, which includes a handle, a faceplate, and a base. The base is used to install on doors and windows with screws, the faceplate covers the base to conceal the screws, and finally, the handle presses the faceplate firmly onto the base. However, because the faceplate needs to rotate to expose or conceal the screws for disassembling and assembling the base, and the handle also needs to rotate to unlock the square core, the fit between the faceplate and the handle cannot be too tight in order for both to rotate independently. This results in the handle not being able to fully press the faceplate, leaving it relatively loose. During daily use, this can easily cause the faceplate to rotate relative to the base, exposing the screws and affecting the user experience. Utility Model Content

[0004] This utility model provides a door and window handle to solve the technical problem of loose decorative covers in existing door and window handles.

[0005] According to one aspect of the present invention, a door / window handle is provided, comprising a base, a cover plate, and a handle. The base is used for mounting on a door or window. The cover plate is disposed on the outside of the base and is used to cover the mounting structure on the base. The handle is provided with a drive shaft that passes sequentially through the cover plate and the base and is used for connecting to a door / window lock. The cover plate includes a cover plate body and an elastic support structure disposed on the side of the cover plate body away from the base. The elastic support structure is used to abut against the handle and elastically press the cover plate body against the base.

[0006] Preferably, the elastic support structure is configured as an annular structure surrounding the drive shaft. The annular structure includes a connecting part and a supporting part. The connecting part is connected to the cover plate body. The supporting part is bent relative to the connecting part in a direction away from the cover plate body to have a gap relative to the cover plate body. The supporting part elastically abuts against the handle.

[0007] Preferably, the support portion is provided in multiple parts, and the multiple support portions are arranged equidistantly around the drive shaft.

[0008] Preferably, the connecting portion includes a connecting boss extending in a direction toward the cover plate body, and the connecting portion is connected to the cover plate body through the connecting boss.

[0009] Preferably, the cover plate body is provided with a first reinforcing rib and a second reinforcing rib on the side facing the base. The width of the first reinforcing rib is greater than the width of the second reinforcing rib. The connection positions of the first reinforcing rib and the connecting part are arranged in a one-to-one correspondence. The second reinforcing rib is arranged as a cross structure that connects the first reinforcing rib and the edge of the cover plate body into an integral whole.

[0010] Preferably, the handle has a receiving cavity, and the elastic support structure is placed inside the receiving cavity.

[0011] Preferably, the handle includes a metal frame and a non-metallic layer covering the outer periphery of the metal frame, and the metal frame is integrally formed with the drive shaft.

[0012] Preferably, the drive shaft includes a round shaft and a square shaft connected in sequence, and the base has a limiting hole adapted to the round shaft on the side facing the cover plate. The round shaft is rotatably inserted into the limiting hole, and the square shaft is used to connect with door and window locks.

[0013] Preferably, the base has a mounting hole coaxially arranged with respect to the limiting hole on the side away from the cover plate, and a spring hole extending radially outward along the mounting hole;

[0014] The door and window handle also includes a limiting gear, a limiting member, and a spring. The limiting gear is located in the mounting hole and has a square hole at its center that matches the square shaft. The sidewall of the limiting gear is provided with multiple limiting grooves spaced circumferentially. The limiting member is used to be embedded in the limiting groove. The spring is pressed into the spring hole and elastically supports the limiting member. When one of the limiting grooves of the limiting gear rotates to face the limiting member, the spring drives the limiting member to pop out and embed into the corresponding limiting groove.

[0015] Preferably, the cover plate body has a clearance hole for the drive shaft to pass through, and the base and / or the edge of the cover plate body has a notch, which is used for the user to pry up the cover plate and drive the cover plate to rotate along the clearance hole to expose the mounting structure on the base.

[0016] This utility model has the following beneficial effects:

[0017] The door and window handle provided by this utility model can be installed on doors and windows via a base. A cover plate is placed on the outside of the base and conceals the mounting structure of the base relative to the door and window, achieving complete concealment of the mounting structure. Furthermore, an elastic support structure is provided on the side of the cover plate away from the base. This elastic support structure abuts against the handle and elastically presses the cover plate against the base, ensuring a tight fixation of the cover plate and effectively preventing it from easily rotating relative to the base during daily use. The elastic support structure also provides reverse support to the handle, preventing it from loosening and improving the handle's feel. Secondly, because the handle and cover plate are supported by the elastic support structure, the end face of the handle and the surface of the cover plate do not need to be tightly fitted, effectively reducing the actual contact area between the handle and the cover plate. This increases the clamping force while preventing excessive friction between the handle and the cover plate, thus preventing the cover plate from rotating synchronously when the handle is turned.

[0018] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[0028] Figures 1 to 4 The present invention provides a door and window handle that is installed on doors and windows and drives door and window locks to lock or unlock. The overall structure is simple and efficient, and the fit is tight, so there will be no loosening problem.

[0029] Please combine Figure 1 and Figure 2The door and window handle 1000 includes a base 1, a cover plate 2, and a handle 3. The base 1 is provided with an installation structure 11 for fixing relative to a door or window. The cover plate 2 covers the outside of the base 1 and is used to cover the installation structure 11 on the base 1. The drive end of the handle 3 is provided with a drive shaft 4. The drive shaft 4 passes through the cover plate 2 and the base 1 in sequence and is used to connect with the door and window lock. Thus, when the handle 3 is driven to rotate, the drive shaft 4 drives the door and window lock to lock or unlock. The cover plate 2 includes a cover plate body 21 and an elastic support structure 22 provided on the side of the cover plate body 21 away from the base 1. The elastic support structure 22 is used to abut against the handle 3 and elastically press the cover plate body 21 onto the base 1.

[0030] Furthermore, the mounting structure 11 includes a plurality of mounting holes arranged around the drive shaft 4. These mounting holes are used to pass bolts through and to connect and fix the structure to the door or window via the bolts. In other embodiments, the mounting structure 11 may also include a positioning pin, a positioning hole, and / or a snap fastener. The positioning pin is used to insert into a pre-set opening on the door or window, the positioning hole is used for positioning a pre-set pin on the door or window, and the snap fastener is used to engage a pre-set slot on the door or window. The specific installation method can be adjusted according to actual needs.

[0031] Specifically, the door and window handle 1000 can be installed on the door or window via the base 1. The cover plate 2 is placed on the outside of the base 1 and covers the mounting structure 11 of the base 1 relative to the door or window, thus completely concealing the mounting structure 11. Furthermore, an elastic support structure 22 is provided on the side of the cover plate body 21 away from the base 1. The elastic support structure 22 abuts against the handle 3 and elastically presses the cover plate body 21 onto the base 1, thus achieving a tight fixation of the cover plate 2. This effectively prevents the cover plate 2 from loosening and being easily rotated relative to the base 1 during daily use. Moreover, the elastic support structure 21 can also press against the handle 3 in the opposite direction, preventing the handle 3 from loosening and improving the feel of the handle 3. Secondly, since the handle 3 and the cover plate body 21 are supported by the elastic support structure 22, the end face of the handle 3 and the surface of the cover plate body 11 do not need to be tightly fitted, which effectively reduces the actual contact area between the handle 3 and the cover plate 2. While increasing the clamping force, it can avoid excessive friction between the handle 3 and the cover plate 2, so that the cover plate 2 will not be driven to rotate synchronously when the handle 3 is driven to rotate.

[0032] like Figure 3As shown, the elastic support structure 22 is an annular structure surrounding the drive shaft 4. The annular structure has at least one connecting part 221 and at least one supporting part 222 along the circumferential direction, and the connecting part 221 and the supporting part 222 are arranged alternately in sequence. The connecting part 221 is fixedly connected to the cover plate body 21. The supporting part 222 is bent relative to the connecting part 221 in a direction away from the cover plate body 21 to have a gap relative to the cover plate body 21, so that the supporting part 222 has elastic force in the direction close to or away from the cover plate body 21. The supporting part 222 elastically abuts against the handle 3.

[0033] The elastic support structure 22 is arranged around the drive shaft 4 in a ring structure, and connecting parts 221 and supporting parts 222 are alternately arranged on the ring structure in sequence. While avoiding the drive shaft 4, it forms at least one elastic support point on the handle 3, realizing elastic support between the cover plate body 21 and the handle 3. The support structure is simple, efficient and occupies little space. Secondly, since the elastic support structure 22 is fixedly connected to the cover plate body 21 through the connecting part 221, that is, the elastic support structure 22 and the cover plate body 21 are integrally formed. Compared with the additional spring, spring sheet and other structures between the cover plate 2 and the handle 3, the number of accessories of the door and window handle 1000 can be reduced. It is convenient to disassemble and assemble, and can avoid the impact on the use effect due to the omission of accessories during the assembly process.

[0034] Preferably, multiple support portions 221 are provided, and these multiple support portions 221 are arranged equidistantly around the drive shaft 4. Similarly, multiple connecting portions 221 are also provided, and these multiple connecting portions 221 are arranged equidistantly around the drive shaft 4. By having multiple support portions 221 respectively form multiple elastic support points arranged around the drive shaft 4, it ensures that the elastic force distribution between the handle 3 and the cover plate body 21 is uniform, avoiding uneven force that could cause the rotation of the cover plate 2 or the handle 3 to become stuck.

[0035] In this embodiment, two support portions 221 are provided, symmetrically arranged on opposite sides of the drive shaft 4; correspondingly, two connecting portions 221 are provided, with the line connecting the two connecting portions 221 perpendicular to the line connecting the two support portions 221, that is, the two connecting portions 221 are also symmetrically arranged on opposite sides of the drive shaft 4. The elastic support structure 22 elastically abuts against the handle 3 through the two support portions 221, and the directional force of the handle 3 causes the two support portions 221 to apply an elastic clamping force to the two connecting portions 221, so that the cover plate body 21 can tightly cover the base 1.

[0036] Preferably, the connecting portion 221 includes a connecting boss 2211 extending in a direction toward the cover plate body 21, and the connecting portion 221 is connected to the cover plate body 21 via the connecting boss 2211. The connecting boss 2211 extends the lever arm of the connecting portion 221 on the cover plate body 21, thereby increasing the elasticity of the support portion 221 and improving the elastic clamping effect.

[0037] like Figure 4 As shown, the cover plate body 21 is provided with a first reinforcing rib 211 and a second reinforcing rib 212 on the side facing the base 1. The width of the first reinforcing rib 211 is greater than the width of the second reinforcing rib 212. The connection positions of the first reinforcing rib 211 and the connecting part 221 are arranged one-to-one. The second reinforcing rib 212 is set as a cross structure that connects the first reinforcing rib 211 and the edge of the cover plate body 21 into a whole.

[0038] Specifically, the number and position of the first reinforcing ribs 211 are respectively arranged corresponding to the connecting part 221. Since the cover plate body 21 mainly bears the clamping force applied by the hand 3 through the connecting part 221, the first reinforcing ribs 211 strengthen and reinforce the connection position of the connecting part 221, and the second reinforcing ribs 212 distribute the force of the first reinforcing ribs 211 to the periphery of the cover plate body 21, which can prevent the cover plate body 21 from being damaged due to the excessive concentration of force and improve durability.

[0039] Preferably, the handle 3 has a receiving cavity 31, and the elastic support structure 22 is placed in the receiving cavity 31. By receiving the elastic support structure 22 in the receiving cavity 31, the elastic support structure 22 can be completely covered and hidden, making the overall shape of the door and window handle 1000 more concise and elegant, and also realizing the protective function of the elastic support structure 22 to prevent foreign objects from entering.

[0040] Preferably, the handle 3 includes a metal frame and a non-metallic layer covering the outer periphery of the metal frame. The metal frame is integrally formed with the drive shaft 4. Compared with a separate design of the handle 3 and the drive shaft 4, this design can further reduce the number of parts, facilitate assembly and use, and improve the installation strength and stability of the drive shaft 4, ensuring that the handle 3 can stably drive the drive shaft 4 to rotate. Secondly, the metal frame can improve the structural strength of the handle 3, increase tensile and torsional strength, and improve durability. Conventional metal handles generally require oxidation, spraying, and electroplating processes to form a protective layer on their outer surface. However, after long-term use in coastal areas, the protective layer may peel off or develop spots. The handle 3, by covering the outer periphery of the metal frame with a non-metallic layer, can improve the strength of the handle 3 while effectively solving problems such as discoloration and peeling on the surface of the handle 3.

[0041] Furthermore, the non-metallic layer can be made of non-metallic materials such as plastic, rubber, leather, wood, ceramics, and synthetic fibers, and can be adjusted according to specific usage requirements or decorative styles to meet more application scenarios.

[0042] like Figure 2 As shown, the drive shaft 4 includes a round shaft 41 and a square shaft 42 connected in sequence. The base 1 has a limiting hole 12 on the side facing the cover plate 2, which is adapted to the round shaft 42. That is, the limiting hole 12 is a round hole, and the inner diameter of the limiting hole 12 is adapted to the outer diameter of the round shaft 41. The round shaft 41 is rotatably inserted into the limiting hole 12. The square shaft 42 is used to connect with door and window locks. The cooperation between the round shaft 41 and the limiting hole 12 radially limits the drive shaft 4, improving the installation accuracy and stability of the drive shaft 4 and preventing it from shaking during use.

[0043] like Figure 4As shown, the base 1 has a mounting hole 13 coaxially arranged with respect to the limiting hole 12 on the side away from the cover plate 2, and a spring hole 14 extending radially outward along the mounting hole 13. The spring holes 14 are arranged in multiple equidistantly along the circumference of the mounting hole 13. Furthermore, the door and window handle 1000 also includes a limiting gear 5, a limiting member 6, and a spring 7. The limiting gear 5 is disposed in the mounting hole 13 and has a square hole 51 at its center that is adapted to the square shaft 42. The side wall of the limiting gear 5 is provided with a plurality of limiting grooves 52 spaced circumferentially. The limiting member 6 is used to be embedded in the limiting groove 52. The spring 7 is pressed into the spring hole 14 and elastically supports the limiting member 6. When one of the limiting grooves 52 of the limiting gear 5 rotates to a state facing the limiting member 6, the spring 7 is used to drive the limiting member 6 to pop out and embed into the corresponding limiting groove 52. The square shaft 42 is used to drive the limiting gear 5 to rotate synchronously when rotating and to push the limiting member 6 to retract against the elastic force of the spring 7.

[0044] Furthermore, the limiting member 6 is a steel ball with a spherical structure, allowing it to smoothly enter the limiting groove 52 and smoothly disengage from it when the handle 3 is rotated, preventing jamming. In use, when the handle 3 drives the square shaft 4 to rotate to a preset angle, the spring 7 elastically pushes the limiting member 6 into the corresponding limiting groove 52, achieving circumferential limiting of the limiting gear 5, thereby achieving circumferential limiting of the handle 3 and improving the feel of the handle 3.

[0045] Please combine Figure 1 and Figure 2 The cover plate body 21 has a clearance hole 213 for the drive shaft to pass through. The base 1 and / or the edge of the cover plate body 21 have a notch 15. The notch 15 is used for the user to pry up the cover plate 5 and rotate the cover plate 5 along the clearance hole 213 to expose the mounting structure 11 on the base 1, improving ease of use. In this embodiment, the notch 15 is provided on the base 1 so that the cover plate 2 can cover and cover the notch 15, achieving the effect of hiding the notch 15.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
