Description
Technical Field
[0001] This utility model relates to the field of handle technology, specifically to a baseless handle. Background Technology
[0002] A handle is a device installed on door and window sashes that serves both to open and to secure the door / window after closing. Traditional handles require a mounting bracket to connect to the door / window to enable opening and closing. The mounting bracket is relatively large, making installation cumbersome and heavy. Furthermore, the mounting bracket can scratch the surface of the door / window during installation, affecting its overall aesthetics.
[0003] Chinese utility model patent with publication number "CN214091379U" discloses a baseless swing lock handle mounting structure, including a handle, a rotating shaft, and a bushing. The rotating shaft fixing block protrudes from the handle and has a bushing mating end. A rotation positioning structure is provided between the bushing mating end and the bushing. The rotation positioning structure includes a spring hole in the bushing, a spring installed in the spring hole, a plate body installed in the bushing, and a recessed hole in the bushing mating end. The plate body has a positioning spherical surface protruding towards the bushing mating end corresponding to the spring hole. The spring protrudes outward from the spring hole and is correspondingly connected to the back of the positioning spherical surface. The recessed hole corresponds to and is connected to the positioning spherical surface. An outer shell is provided on the outside of the bushing.
[0004] However, the aforementioned baseless square steel handle still has the following drawbacks: the rotation positioning structure requires the spring inside the spring hole to press against the positioning spherical surface of the plate, so that the positioning spherical surface of the plate can be inserted into the concave hole to achieve rotation positioning. When the handle is rotated, the positioning spherical surface of the plate will be squeezed, and the positioning spherical surface is prone to wear and dent, causing the handle to loosen. At the same time, the handle has many parts, making assembly more complicated.
[0005] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content
[0006] The purpose of this invention is to provide a baseless handle that is stable in rotational positioning, simple in structure, and easy to assemble, so as to solve the above-mentioned problems existing in the prior art.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a baseless handle, including a handle, a mounting base, a rotating base, and a square shaft. The mounting base has a mounting hole in the middle, and the handle mounting area has a fixing hole. One end of the rotating base is rotatably connected to the mounting hole, and the other end is hinged to the fixing hole. The rotating base has a shaft hole in the middle for mounting the square shaft. The feature is that: a plurality of positioning keyways are spaced apart on the periphery of the rotating base, a positioning plate that is linked with the positioning keyways is provided in the mounting base, and a plurality of positioning springs that abut against the positioning plate are provided in the mounting base.
[0008] By adopting the above technical solution: the handle is installed inside the door or window through the mounting base. The shaft hole in the middle of the rotating base is square and fits the square shaft. When the handle is in the initial position, the positioning plate is abutted in the positioning keyway by the positioning spring, locking the rotating base in place. The handle will not rotate due to accidental operation. When the handle is manually rotated, the square shaft can rotate with the rotating base. The positioning plate disengages from the positioning keyway and squeezes the positioning spring. The positioning spring is compressed. When the positioning plate rotates through the middle of the arc surface between the positioning keyways, the positioning spring applies an oblique force, causing the positioning plate to smoothly lock into the next positioning keyway. This achieves precise positioning and stable retention of the handle in different positions, while also reducing the complexity of assembly and maintenance of the handle.
[0009] The aforementioned baseless handle can be further configured as follows: the mounting base is provided with a positioning block, the two ends of the positioning block are provided with arc-shaped limiting parts, and a receiving groove is formed between the limiting parts. The two ends of the positioning plate can abut against the end face of the arc-shaped limiting part. The positioning spring is provided in the receiving groove, one end of the positioning spring abuts against the side wall of the receiving groove, and the other end abuts against the side wall of the positioning plate.
[0010] By adopting the above technical solution: the limiting parts at both ends of the positioning block can limit the movement range of the positioning plate during movement, preventing the positioning spring from being over-compressed at one end of the positioning plate and causing the positioning spring to fail. At the same time, when the handle rotates, it can provide a resisting force to the handle before the positioning plate rotates past the middle of the arc surface between the positioning keyways, preventing incorrect opening or closing due to misoperation. Furthermore, it provides an accelerating force when rotating past the middle of the arc surface, so that the handle can automatically rotate until the positioning plate is engaged in the positioning keyway. In addition, the receiving groove between the limiting parts can ensure that the spring is subjected to uniform force during operation, extending the service life of the spring, while further enhancing the elastic reset capability of the positioning plate and improving the positioning accuracy and reliability of the handle.
[0011] The aforementioned baseless handle can be further configured as follows: the mounting base is covered with a fixing plate, the fixing plate has a rotating hole in the middle, the rotating base passes through the rotating hole and engages with the handle, the positioning plate and the inner wall of the mounting base form a mounting groove, the end face of the fixing plate has a mounting block, the mounting block can be inserted into the mounting groove; the rotating base has an annular groove, the annular groove has a limiting retaining ring, the limiting retaining ring abuts against the end face of the mounting base.
[0012] By adopting the above technical solution: the fixing plate rotates and engages with the rotating seat through the rotating hole. The fixing plate can protect the positioning plate and positioning spring inside the mounting seat, preventing dust or liquid from entering the mounting seat and causing rotational positioning failure, thus improving the stability of the handle rotational positioning. In addition, the gap between the limiting block and the inner wall of the mounting seat forms a mounting groove. The fixing plate can be quickly assembled with the mounting seat by the mounting block extending along the axis of the rotating seat through its end face. The limiting ring is locked into the ring groove, which fixes the fixing plate and prevents the fixing plate from loosening with the mounting seat, while improving the stability of the connection between the rotating seat and the mounting seat.
[0013] The aforementioned baseless handle can be further configured as follows: a fixing ring is provided on the end face of the mounting base away from the fixing plate, and a fixing step is provided on the side of the mounting base opposite to the fixing ring. A through hole is provided in the middle of the fixing ring along the axial direction of the mounting base through the fixing step, and a sliding part is provided on the side of the fixing step to slide with the rotating base.
[0014] By adopting the above technical solution: the mounting base ensures the handle is stably positioned at the mounting point by inserting a fixing ring, and then the handle is installed on the door or window by passing screws through the through hole. At the same time, the mounting base remains stable during the rotation of the handle, preventing loosening or displacement due to external force or long-term use. The fixing step improves the structural strength of the mounting base, preventing damage caused by excessive installation force. Furthermore, the sliding part makes the connection between the rotating seat and the mounting base smoother, reducing friction and wear, while ensuring the flexible rotation of the rotating seat and improving the service life of the handle.
[0015] The aforementioned baseless handle can be further configured as follows: the fixed step has a groove at the end of the through hole, the mounting base has an installation notch connected to the groove, the fixing plate has a fixing block, the fixing block can abut against the fixed step, and the fixing block has a slot hole that is linked with the groove.
[0016] By adopting the above technical solution: the slot can accommodate the flat end of the screw, and the through hole can accommodate screws of different sizes, which improves the adaptability of the mounting base during installation. The fixing block on the fixing plate has the same shape as the fixing step, and the fixing block is tightly connected to the end face of the fixing step, which further improves the dustproof capability of the mounting base. At the same time, the slot allows the fixing plate to be fixed to the mounting base before being installed on the door and window, which optimizes the installation process of the handle and improves the convenience of the handle installation.
[0017] The aforementioned baseless handle can be further configured as follows: a support block for supporting the handle is symmetrically arranged on the end face of the fixed plate, the mounting base is covered with a sleeve, the sleeve has a sleeve hole, the sleeve hole has a limiting block, and the limiting block abuts and cooperates with the end of the support block.
[0018] By adopting the above technical solution: the support block can abut against the end face of the handle mounting point, providing stable support for the handle and ensuring that the handle will not shake or tilt during rotation. The sleeve is fitted onto the outer surface of the mounting base, which not only protects the mounting base from damage caused by bumps during installation, but also improves the overall aesthetics of the handle. At the same time, the side wall of the limiting block abuts against the end of the support block, allowing the sleeve to be quickly positioned during installation. In addition, the limiting block covers the end of the slot, which can block the slot and prevent dust or rainwater from entering the through hole and corroding the screw, thus improving the service life of the handle.
[0019] The aforementioned baseless handle can be further configured such that the mounting base has several mounting protrusions spaced apart around its circumference.
[0020] By adopting the above technical solution: the mounting protrusion has a certain deformation capability. When the sleeve is fitted onto the mounting base, the mounting protrusion can improve the tightness of the connection between the mounting base and the sleeve, and improve the stability of the connection between the sleeve and the mounting base. At the same time, the mounting base can be adapted to various sleeves of different shapes through the mounting protrusion, thus improving the applicability of the handle.
[0021] The aforementioned baseless handle can be further configured such that: a first hinge hole is provided in the fixing hole on the side of the handle, and a second hinge hole is provided in the shaft hole at the end of the rotating seat; a hinge bolt is internally threaded into the first hinge hole and the second hinge hole, and the end of the hinge bolt can abut against the square shaft.
[0022] By adopting the above technical solution, the hinge bolt is threaded into the first hinge hole and the second hinge hole, and its end abuts against the side wall of the square shaft, making the connection between the handle and the rotating seat more secure. At the same time, the square shaft is fastened in the shaft hole, making the connection between the square shaft and the rotating seat more stable. In addition, when it is necessary to replace different handles, the hinge bolt can be disengaged from the second hinge hole to pull the handle out along the central axial direction of the rotating seat for smoother operation, which improves the convenience of handle maintenance.
[0023] The beneficial effects of this utility model are as follows:
[0024] First, the handle achieves rotational positioning by setting a positioning plate and positioning spring in the mounting base, and by cooperating with multiple positioning keyways spaced circumferentially on the positioning plate and the rotating base. Compared with the sliding snap-fit method of the bushing through the concave hole and positioning ball, the structure of the positioning plate and positioning keyway is more stable. Multiple positioning springs ensure that the positioning plate can always be linked with the positioning keyway, making assembly more convenient and quick. At the same time, it simplifies the internal structure of the handle, reduces the overall size of the handle, and can be used in various spaces of different sizes.
[0025] Secondly, the mounting base, through the fixing plate, can provide good protection for the positioning plate and positioning spring, effectively preventing dust and rainwater from seeping into the mounting base and extending the service life of the handle. At the same time, the mounting base is fitted with a snap-fit sleeve, which further improves the protection of the mounting base and enhances the overall aesthetics of the handle.

Detailed Implementation
[0034] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0035] Example 1: As Figures 1 to 4The illustrated baseless handle includes a handle 1, a mounting base 2, a rotating base 3, and a square shaft 4. The mounting base 2 has a mounting hole 21 in the middle, and the handle 1 has a fixing hole 11 at the mounting position. One end of the rotating base 3 is rotatably connected to the mounting hole 21, and the other end is hinged to the fixing hole 11. The rotating base 3 has a shaft hole 31 in the middle for mounting the square shaft 4. Several positioning keyways 32 are spaced apart on the periphery of the rotating base 3. The mounting base 2 has a positioning plate 22 that is linked with the positioning keyways 32. The mounting base 2 also has several positioning springs 23 that abut against the positioning plate 22. The handle is installed inside the door or window via the mounting base 2. The shaft hole 31 in the middle of the rotating base 3 is square and fits the square shaft 4. When the handle is in the initial position, the positioning plate 22 is abutted in the positioning keyway 32 by the positioning spring 23, which locks the rotating base 3 in place. The handle will not rotate due to slight force. When the handle 1 is manually rotated, the square shaft 4 can rotate with the rotating base 3. The positioning plate 22 disengages from the positioning keyway 32 and squeezes the positioning spring 23. The positioning spring 23 is compressed. When the positioning plate 22 rotates through the middle of the arc surface between the positioning keyways 32, the positioning spring 23 applies an oblique force, so that the positioning plate 22 smoothly locks into the next positioning keyway 32. This achieves precise positioning and stable retention of the handle in different positions, while also reducing the complexity of assembly and maintenance of the handle.
[0036] Mounting base 2 is provided with positioning block 24, and the two ends of positioning block 24 are provided with arc-shaped limiting parts 241. A receiving groove 242 is formed between the limiting parts 241. The two ends of positioning plate 22 can abut against the end face of arc-shaped limiting part 241. Positioning spring 23 is provided in receiving groove 242. One end of positioning spring 23 abuts against the side wall of receiving groove 242 and the other end abuts against the side wall of positioning plate 22. The limiting parts 241 at both ends of the positioning block 24 can limit the movement range of the positioning plate 22 during movement, preventing the positioning plate 22 from over-compressing the positioning spring 23 and causing the positioning spring 23 to fail. At the same time, when the handle rotates, it can provide a resisting force to the handle before the positioning plate 22 rotates past the middle of the arc surface between the positioning keyway 32, preventing incorrect opening or closing due to misoperation. And when it rotates past the middle of the arc surface, it provides an accelerating force, so that the handle can automatically rotate until the positioning plate 22 is engaged in the positioning keyway 32 after rotation. In addition, the receiving groove 242 between the limiting parts 241 can ensure that the spring is evenly stressed during operation, extend the service life of the spring, and further enhance the elastic restoring ability of the positioning plate 22, thereby improving the positioning accuracy and reliability of the handle.
[0037] Mounting base 2 is covered by fixing plate 5. Fixing plate 5 has a rotating hole 51 in the middle. Rotating base 3 passes through rotating hole 51 and engages with handle 1. Positioning plate 22 and inner wall of mounting base 2 form mounting groove 25. Fixing plate 5 has mounting block 52 on end face. Mounting block 52 can be inserted into mounting groove 25. Rotating base 3 has annular groove 33. Limiting retaining ring 34 is provided in annular groove 33. Limiting retaining ring 34 abuts against end face of mounting base 2. The fixing plate 5 rotates with the rotating seat 3 through the rotating hole 51. The fixing plate 5 provides protection for the positioning plate 22 and positioning spring 23 inside the mounting seat 2, preventing dust or liquid from entering the mounting seat 2 and causing rotational positioning failure, thus improving the stability of the handle rotational positioning. The gap between the limiting block 62 and the inner wall of the mounting seat 2 forms the mounting groove 25. The fixing plate 5 is inserted into the mounting groove 25 by the mounting block 52 extending along the axis of the rotating seat 3, so that the fixing plate 5 can be quickly assembled with the mounting seat 2. The limiting ring 34 is inserted into the ring groove 33, which fixes the fixing plate 5 and prevents the fixing plate 5 from loosening with the mounting seat 2, while improving the stability of the connection between the rotating seat 3 and the mounting seat 2.
[0038] A fixing ring 26 is provided on the end face of the mounting base 2 away from the fixing plate 5. A fixing step 27 is also provided on the side of the mounting base 2 opposite to the fixing ring 26. A through hole 271 is opened in the middle of the fixing ring 26 along the axial direction of the mounting base 2 through the fixing step 27. A sliding part 272 is provided on the side of the fixing step 27 to slide with the rotating base 3. The mounting base 2 ensures that the handle is stably installed at the mounting position by inserting the fixing ring 26 into the mounting position. Then, the screw is passed through the through hole 271 to install the handle on the door or window. At the same time, the mounting base 2 can maintain stability during the rotation of the handle, avoiding loosening or displacement due to external force or long-term use. The fixing step 27 improves the structural strength of the mounting base 2 and prevents the mounting base 2 from being damaged due to excessive installation force. The sliding part 272 makes the connection between the rotating base 3 and the mounting base 2 smoother, reduces friction and wear, and ensures the flexible rotation of the rotating base 3, thereby improving the service life of the handle.
[0039] The fixed step 27 has a slot 273 at the end of the through hole 271. The mounting base 2 has an installation notch 274 connected to the slot 273. The fixing plate 5 has a fixing block 53, which can abut against the fixed step 27. The fixing block 53 has a slot hole 54 that is linked with the slot 273. The slot 273 can accommodate the flat end of the screw. Combined with the installation notch 274, the through hole 271 can accommodate screws of different sizes, which improves the adaptability of the mounting base 2 during installation. The fixing block 53 on the fixing plate 5 has the same shape as the fixed step 27. The fixing block 53 is tightly connected to the end face of the fixed step 27, which further improves the dustproof capability of the mounting base 2. At the same time, the slot hole 54 allows the fixing plate 5 to be fixed to the mounting base 2 before being installed on the door or window, which optimizes the installation process of the handle and improves the convenience of the handle installation.
[0040] The fixed plate 5 has a support block 55 symmetrically arranged on its end face to support the handle 1. The mounting base 2 is covered by a sleeve 6, which is polygonal in shape and has a sleeve hole 61 in the middle. The sleeve hole 61 has a limiting block 62, which abuts against the end of the support block 55. The support block 55 can abut against the end face of the handle 1, providing stable support for the handle 1 and ensuring that the handle 1 will not shake or tilt during rotation. The sleeve 6 is fitted on the outer surface of the mounting base 2, which not only protects the mounting base 2 from damage caused by bumps during installation, but also improves the overall aesthetics of the handle. At the same time, the side wall of the limiting block 62 abuts against the end of the support block 55, allowing the sleeve 6 to be quickly positioned during installation. In addition, the limiting block 62 covers the end of the slot 54, which can block the slot 273 and prevent dust or rainwater from entering the through hole 271 and corroding the screws, thus improving the service life of the handle.
[0041] The mounting base 2 has several mounting protrusions 28 spaced around its circumference. The mounting protrusions 28 have a certain deformation capacity. When the housing 6 is fitted onto the mounting base 2, the mounting protrusions 28 can improve the tightness of the connection between the mounting base 2 and the housing 6, and improve the stability of the connection between the housing 6 and the mounting base 2. At the same time, the mounting base 2 can be adapted to various housings 6 with different shapes through the mounting protrusions 28, thus improving the applicability of the handle.
[0042] The handle 1 has a first hinge hole 12 connected to the fixing hole 11 on its side, and a second hinge hole 35 connected to the shaft hole 31 at the end of the rotating seat 3. A hinge bolt 13 is internally threaded into the first hinge hole 12 and the second hinge hole 35, and the end of the hinge bolt 13 can abut against the square shaft 4. The hinge bolt 13 is threaded into the first hinge hole 12 and the second hinge hole 35, and its end abuts against the side wall of the square shaft 4, making the connection between the handle 1 and the rotating seat 3 more secure. At the same time, it fastens the square shaft 4 into the shaft hole 31, making the connection between the square shaft 4 and the rotating seat 3 more stable. In addition, when it is necessary to replace different handles 1, the handle 1 can be pulled out along the central axis of the rotating seat 3 by disengaging the hinge bolt 13 from the second hinge hole 35, which improves the convenience of handle maintenance.
[0043] Example 2: The difference between Example 2 and Example 1 is that, as Figure 5 , Figure 6 The handle housing 6 shown is generally circular, and a fingerprint groove is provided on the side of the handle 1 near the mounting base 2, which can realize automatic unlocking of the handle through fingerprint recognition.
[0044] The working principles of Embodiments 1 and 2 are as follows: During assembly, the rotating seat 3 is first inserted into the mounting hole 21 of the mounting base 2. Then, the positioning plate 22 is installed into the mounting base 2, and the positioning spring 23 is installed into the receiving groove 242 of the positioning block 24, so that the side wall of the positioning plate 22 engages with the positioning keyway 32 of the rotating seat 3. Afterward, the fixing plate 5 is mounted on the mounting base 2 via the mounting block 52 and the mounting groove 25. The fixing of the mounting base 2, the rotating seat 3, and the fixing plate 5 is achieved by engaging the limiting ring 34 into the ring groove 33. After installation, insert the square shaft 4 into the shaft hole 31, then insert the handle mounting base 2 into the mounting location through the fixing ring 26, and fix the mounting base 2 to the door or window by passing the screw through the slot hole 54 and the through hole 271. Then, insert the sleeve 6 into the mounting base 2 to protect and cover the mounting base 2 and the fixing plate 5. Finally, insert the end of the rotating base 3 into the fixing hole 11 to assemble the handle 1, the mounting base 2, and the rotating base 3. Screw the hinge bolt 13 into the first hinge hole 12 and through the second hinge hole 35 to abut against the side wall of the square shaft 4 to complete the installation of the entire handle.
[0045] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
