Technical Field
[0001] This utility model relates to the field of handle technology, and more specifically, to a handle structure and a door / window. Background Technology
[0002] A handle is a device installed on door and window sashes that serves both to open and secure them after closing. Existing handles are usually designed with internal splicing assembly, but the splicing structure is unstable, parts are prone to loosening, and there is a lack of easy assembly solutions, resulting in low installation efficiency. Utility Model Content
[0003] To address at least one of the aforementioned problems, this utility model first provides a handle structure, including a handle, a rotating component, a sliding component, a spring, and a base for fixing to a door or window. The handle and the base are rotatably connected. The handle includes a connecting portion with a non-circular vertical cross-section. The rotating component is sleeved on the connecting portion and rotates with it. The rotating component has a rotating part with a non-circular vertical cross-section. The rotating part rotates and pushes the sliding component, causing it to move in the left-right direction. The sliding component is installed inside the base. The spring simultaneously abuts against the sliding component and the base, and the spring is used to reset the sliding component.
[0004] Optionally, it also includes a fixing plate, the base is provided with a receiving groove, the fixing plate is installed in the receiving groove, the fixing plate is provided with a sliding groove, the sliding member is provided with a sliding part, and the sliding part slides along the sliding groove.
[0005] Optionally, the sliding member is provided with a mounting groove, one end of the spring is accommodated in the mounting groove, and spring seats are recessed on both the left and right side walls of the accommodating groove. The other end of the spring is limited between the upper and lower end walls of the spring seat, and the two ends of the spring in the left and right direction respectively abut against the spring seat and the inner wall of the mounting groove.
[0006] Optionally, it also includes a retaining ring, wherein a retaining groove is provided on the outer wall of the connecting part, the retaining ring is installed in the retaining groove, and the upper limit of the rotating member in the front-to-back direction is located between the retaining ring and the base.
[0007] Optionally, there are two sliding members symmetrically arranged on the left and right sides of the rotating member, and two springs are respectively provided at the upper and lower ends of the side wall of the sliding member.
[0008] Optionally, the sliding member is provided with an abutment portion, and the rotating part rotates to abut the abutment portion and pushes the abutment portion to move in the left and right direction.
[0009] Optionally, the rotating member is provided with a flange located at the front end of the abutting portion, and the sliding member is provided with an arc-shaped opening for avoiding the flange.
[0010] Optionally, it also includes a connecting ring, which is sleeved on the connecting part, and the front and rear ends of the connecting ring abut against the base and the handle, respectively.
[0011] Optionally, it also includes a connecting shaft with a non-circular vertical cross-section. One end of the connecting shaft is inserted into the connecting part and rotates with the connecting part, while the other end of the connecting shaft is inserted into the connecting part of another handle.
[0012] Compared with the prior art, the handle structure in this utility model allows the base to be directly and quickly fixed to the pre-set holes in the door and window with screws. After the base is installed, a receiving cavity is formed between it and the door and window. The rotating parts, sliding parts and springs are all accommodated in the receiving cavity. As a pre-assembled functional module, it can be conveniently installed into the receiving cavity as a whole, which greatly simplifies the on-site installation steps and improves the assembly efficiency.
[0013] Both the connecting part and the rotating part have non-circular vertical cross-sections. This ensures that the rotating part rotates synchronously with the connecting part, guaranteeing reliable transmission without slippage. Furthermore, the distance from the center to the edge of this non-circular shape is unequal, with a long end and a short end. When no external force is applied to the handle, the short end of the rotating part abuts against the sliding component. When the handle is rotated by an external force, the connecting part drives the rotating part to rotate, pushing the sliding component to slide. The distance difference between the long and short ends causes the spring to be pushed and compressed. When the external force is released from the handle, the spring force causes the sliding component to slide back to its original position, and the sliding component pushes the rotating part to rotate. The structure is stable, the entire process operates smoothly, and there is no impact noise.
[0014] In addition, this utility model provides a door or window, including the handle structure described above.
[0015] Compared with the prior art, the door and window described in this utility model have the same advantages as the handle structure described above, which will not be repeated here. Attached Figure Description

Detailed Implementation
[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0026] The accompanying drawings of the embodiments of this utility model provide a coordinate system XYZ, where the positive direction of the X-axis represents the left and the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front and the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top and the negative direction of the Z-axis represents the bottom.
[0027] This utility model embodiment provides a handle structure, combined with Figures 1 to 7 As shown, the device includes a handle 1, a rotating component 3, a sliding component 4, a spring 5, and a base 2 for fixing to a door or window. The handle 1 and the base 2 are rotatably connected. The handle 1 includes a connecting part 11 with a non-circular vertical cross-section. The rotating component 3 is sleeved on the connecting part 11 and rotates with the connecting part 11. The rotating component 3 has a rotating part 31 with a non-circular vertical cross-section. The rotating part 31 rotates and pushes the sliding component 4, causing the sliding component 4 to move in the left and right direction. The sliding component 4 is installed inside the base 2. The spring 5 simultaneously abuts against the sliding component 4 and the base 2, and the spring 5 is used to reset the sliding component 4.
[0028] like Figure 1 and Figure 2As shown, the base 2 can be directly and quickly fixed to the pre-set holes in the door and window using screws. After installation, the base 2 forms a receiving cavity with the door and window. The rotating part 3, the sliding part 4, and the spring 5 are all accommodated in the receiving cavity. As a pre-assembled functional module, it can be conveniently installed into the receiving cavity as a whole, greatly simplifying the on-site installation steps and improving assembly efficiency. The handle 1 and the base 2 are rotatably connected through the connecting part 11. The handle 1 is integrally molded, with a stable structure, and can effectively bear the torque generated by the frequent rotation of the handle 1.
[0029] Both the connecting part 11 and the rotating part 31 have non-circular vertical cross-sections, ensuring that the connecting part 11 can drive the rotating part 31 to rotate synchronously when rotating, resulting in reliable transmission without slippage. Furthermore, the distance from the center to the edge of this non-circular shape is unequal, with a long end distance and a short end distance. When no external force is applied to the handle 1, the short end distance of the rotating part 31 abuts against the sliding member 4. When the handle 1 is rotated by an external force, the connecting part 11 drives the rotating part 31 to rotate, pushing the sliding member 4 to slide. The distance difference between the long end distance and the short end distance causes the spring 5 to be pushed and compressed. When the external force is released from the handle 1, the elastic force of the spring 5 drives the sliding member 4 to slide back to its original position, and the sliding member 4 pushes the rotating part 31 to rotate.
[0030] In this embodiment, both the connecting part 11 and the rotating part 31 have a racetrack-shaped vertical cross-section. This rounded corner at the junction of the long and short ends ensures a smooth transition, making the rotation and pushing process smoother and reducing the likelihood of jamming. This further enhances the smoothness of operation and the lifespan of the structure. The entire process runs smoothly without impact noise.
[0031] like Figure 5 and Figure 7 As shown, optionally, the handle structure further includes a fixing plate 6, the base 2 is provided with a receiving groove 21, the fixing plate 6 is installed in the receiving groove 21, the fixing plate 6 is provided with a sliding groove 61, the sliding member 4 is provided with a sliding part 41, and the sliding part 41 slides along the sliding groove 61.
[0032] In this embodiment, the fixing plate 6 is embedded in the receiving groove 21 and fixed in place. Both the upper and lower ends of the fixing plate 6 protrude forward to form limiting walls 62. The sliding groove 61 is provided on the limiting wall 62 and extends in the left and right direction. The sliding part 41 is provided at the upper and lower ends of the sliding member 4. The sliding part 41 is block-shaped or strip-shaped. The limiting wall 62 restricts the position of the sliding member 4 from the upper and lower direction, and the sliding groove 61 restricts the position of the sliding part 41 from the front and back direction. During the sliding process, the sliding member 4 is not prone to overturning, tilting or jamming due to uneven force, which greatly improves the reliability of the action and the stability of the structure. The structure is simple and easy to install.
[0033] like Figure 2As shown, optionally, the sliding member 4 is provided with a mounting groove 42, one end of the spring 5 is accommodated in the mounting groove 42, and spring seats 22 are recessed on both the left and right side walls of the accommodating groove 21. The other end of the spring 5 is limited between the upper and lower end walls of the spring seat 22, and the two ends of the spring 5 in the left and right directions respectively abut against the inner wall of the spring seat 22 and the mounting groove 42.
[0034] In this embodiment, the mounting groove 42 is cylindrical, and the axis of the spring 5 is located in the left-right direction. The two ends of the spring 5 are limited between the mounting groove 42 and the spring seat 22. This design ensures that the spring 5 is always compressed and released on the preset axis, and the force at both ends is uniform. This avoids problems such as loss of elasticity, abnormal noise due to wear, or inaccurate reset caused by the bending or deflection of the spring 5, and significantly improves the working life of the spring 5 and the reliability of the reset action.
[0035] like Figure 2 and 3 As shown, optionally, the handle structure further includes a retaining ring 9, and a retaining groove 111 is provided on the outer wall of the connecting part 11. The retaining ring 9 is installed in the retaining groove 111, and the upper limit of the rotating member 3 in the front-back direction is located between the retaining ring 9 and the base 2.
[0036] In this embodiment, the retaining ring 9 is a non-closed circular ring with a certain elastic force. It facilitates insertion into the retaining groove 111 from either the top-bottom or left-right direction. The retaining ring 9 effectively prevents axial movement of the rotating component 3 during rotation. This axial positioning method is simple in structure and convenient to install, reducing manufacturing costs and assembly difficulty while ensuring structural stability.
[0037] like Figure 2 As shown, optionally, there are two sliding members 4 symmetrically arranged on the left and right sides of the rotating member 3, and two springs 5 are respectively provided at the upper and lower ends of the side wall of the sliding member 4.
[0038] In this embodiment, the symmetrical layout of the double sliding member 4 and the four springs 5 ensures that the rotating member 3 receives a uniform and balanced pushing force and restoring force regardless of whether it rotates clockwise or counterclockwise. This eliminates the eccentric torque that may be generated by unilateral force, making the movement of the sliding member 4 smoother and more stable. It also greatly enhances the load-bearing capacity, torsional stiffness, and operating feel of the entire handle structure, making it suitable for scenarios requiring higher frequency and intensity of use.
[0039] like Figure 7 As shown, optionally, the sliding member 4 is provided with an abutment portion 43, the rotating part 31 rotates to abut the abutment portion 43, and pushes the abutment portion 43 to move in the left and right direction.
[0040] In this embodiment, the rotating part 31 directly abuts against and acts on the abutting part 43 during rotation, thereby efficiently converting the rotational motion into precise linear movement of the abutting part 43 and the entire sliding member 4 in the left and right directions. This direct-push method has high force transmission efficiency, rapid structural response, no intermediate conversion links, and small delay, making the operation of the handle more direct and precise.
[0041] like Figure 2 and Figure 6 As shown, optionally, the rotating member 3 is provided with a flange 32, the flange 32 is located at the front end of the abutting part 43, and the sliding member 4 is provided with an arc-shaped opening 44, the arc-shaped opening 44 is used to avoid the flange 32.
[0042] In this embodiment, the flange 32 acts as a reinforcing rib, improving the local strength and rigidity of the pushing part. The arc-shaped opening 44 provides ample clearance for the flange 32 throughout the entire movement, preventing any form of mechanical interference between the two during rotation or sliding, and ensuring smooth and unobstructed operation.
[0043] like Figure 3 and Figure 4 As shown, optionally, the handle structure further includes a connecting ring 7, which is sleeved on the connecting part 11, and the front and rear ends of the connecting ring 7 abut against the base 2 and the handle 1, respectively.
[0044] In this embodiment, the connecting ring 7 is used to fill the assembly gap between the handle 1 and the base 2, eliminate axial wobble, and make the handle 1 connection more stable; at the same time, it also serves as a replaceable wear-resistant part, effectively reducing direct friction and wear between the handle 1 and the base 2, protecting the core components, extending the product's service life, and facilitating later maintenance.
[0045] like Figure 1 As shown, optionally, the handle structure further includes a connecting shaft 8, the vertical cross-section of which is non-circular, one end of which is inserted into the connecting part 11 and rotates with the connecting part 11, and the other end of which is inserted into the connecting part 11 of another handle 1.
[0046] In this embodiment, the vertical cross-section of the connecting shaft 8 is square. The connecting shaft 8 realizes the synchronous and linked rotational movement of the handles 1 on both sides of the door and window, ensuring the synchronicity and consistency of the operation on both sides, improving the overall quality of the product and the user experience, and is the core component of the linkage handle system.
[0047] This invention significantly improves the stability of the sliding component 4 by introducing a guide combination of a fixed plate 6 and a sliding groove 61; the optimized spring 5 mounting structure ensures accurate and reliable reset force; the snap ring 9 achieves efficient and reliable axial positioning of the rotating component 3; the symmetrical layout of the two sliding components 4 and four springs 5 greatly enhances the rigidity and balance of the structure; the design of the abutment part 43 ensures efficient and direct force transmission; the avoidance design of the flange 32 and the arc-shaped opening 44 avoids motion interference; the application of the connecting ring 7 reduces wear and eliminates wobbling; and the connecting shaft 8 enables synchronous linkage of the two handles 1. These solutions work together to enhance the stability, reliability, durability, and operating feel of the handle structure, while also greatly improving production assembly efficiency and ease of later maintenance, resulting in excellent overall performance.
[0048] Another embodiment of this utility model provides a door or window, including the handle structure described above.
