Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to a handle structure and a door leaf. Background Art

[0002] Currently, in the field of glass doors and windows, due to the particularity of glass materials (including the inability to drill holes arbitrarily), non-circular tube door handles and all symmetrical door handles are usually fixed by screwing the bottom of the handle. During installation, due to the short distance between the bottom tightening screw and the glass door and the obstruction of the handle body, the tightening screw cannot be tightened quickly with a screwdriver or an Allen wrench, and can only be tightened a small half turn each time, which is very inconvenient to install. At the same time, because the handle is fixed with a single-point tightening screw, there is a large gap inside the handle. After using the handle for a period of time, it is very easy to loosen, and the bottom tightening screw needs to be re-tightened. After repeated several times, the handle hole is loose, and the handle needs to be replaced as a whole, which has a short service life. Utility Model Content

[0035] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, a handle structure 10 is provided, which is used to be installed on a body 20 to be installed, and a first connection hole is provided on the body 20 to be installed. The handle structure 10 includes a first handle 100, a mounting member 200, a locking member 300, a second handle 400 and a tightening member 500. Among them, the end surface of the first handle 100 facing the body 20 to be installed is provided with a second connection hole 110. The mounting member 200 and the first handle 100 are respectively located on both sides of the body 20 to be installed, and a clamping portion 210 is provided on the side of the mounting member 200 away from the first handle 100, and a filling groove 220 is provided on the bottom surface of the clamping portion 210. The mounting member 200 is also provided with a third connection hole 230, and the third connection hole 230 passes through the clamping portion 210. The locking member 300 passes through the third connection hole 230 and the first connection hole in sequence and extends into the second connection hole 110 to lock and match the mounting member 200, the body 20 to be installed and the first handle 100. The second handle 400 and the mounting member 200 are located on the same side of the body 20 to be mounted. A clamping groove 410 is provided on the bottom surface of one end of the second handle 400 facing the body 20 to be mounted. The clamping groove 410 is used to clamp and limit the clamping portion 210 when the second handle 400 is mounted on the mounting member 200. The pressing member 500 is used to be inserted into the filling groove 220 when the second handle 400 is mounted on the mounting member 200, so that the clamping portion 210 is deformed to press against the inner wall of the clamping groove 410.

[0037] When installing the handle structure 10 in the above embodiment, first, the first handle 100 and the mounting member 200 are placed on both sides of the body 20 to be installed, and then the mounting member 200, the body 20 to be installed and the first handle 100 are locked together by the locking member 300. Then, the second handle 400 is put on the mounting member 200 from top to bottom by using the clamping limit of the clamping groove 410 and the clamping portion 210. The second handle 400 is in a loose state relative to the mounting member 200, but will not fall off the mounting member 200. Finally, the pressing member 500 is inserted into the filling groove 220 from bottom to top, so that the clamping portion 210 is deformed, the gap between the clamping portion 210 and the inner wall of the clamping groove 410 disappears, and the clamping portion 210 presses against the inner wall of the clamping groove 410, ensuring that the second handle 400 is stably and reliably fixed on the mounting member 200, and the installation of the handle structure 10 is completed. Compared with the existing door handles, the handle structure 10 in the present application has at least the following advantages: 1. The second handle 400 is mounted on the mounting member 200 by hanging, and can be operated by one person with both hands and installed in place at one time. 2. The second handle 400 and the mounting member 200 are fixed by a tightening member 500 installed from bottom to top, which is simple and convenient to operate. 3. The deformed clamping part 210 can be squeezed with the second handle 400 in a multi-faceted manner to ensure that there is no active gap between the mounting member 200 and the second handle 400, and it is not easy to loosen. After long-term use, it can maintain overall stability without shaking. The handle structure 10 has a long service life and a low maintenance rate.

[0038] Among them, the handle structure 10 can be a non-circular tube door handle structure or a symmetrical door handle structure. The body 20 to be installed can be a cabinet door, a window door, an ordinary door or other objects that need to be installed with handles. Specifically in this embodiment, the first handle 100 and the second handle 400 are fixedly installed on both sides of the body 20 to be installed through the mounting member 200, the locking member 300 and the top member 500. There can be multiple end surfaces of the first handle 100 facing the body 20 to be installed, and there can be multiple end surfaces of the second handle 400 facing the body 20 to be installed. The end surfaces of each first handle 100 facing the body 20 to be installed and the end surfaces of each second handle 400 facing the body 20 to be installed are fixedly installed on both sides of the body 20 to be installed through the mounting member 200, the locking member 300 and the top member 500.

[0039] Among them, the locking member 300 passes through the third connecting hole 230 and the first connecting hole in sequence and extends into the second connecting hole 110 to lock the mounting member 200, the body to be installed 20 and the first handle 100. It means that the locking member 300 can pass through the third connecting hole 230 and the first connecting hole in sequence and extend into the second connecting hole 110 to fix the mounting member 200, the body to be installed 20 and the first handle 100 as a whole.

[0040] Among them, the mounting member 200 can be configured to install a locking plate, a mounting block or other mounting structures. The second connecting hole 110 can be configured to be a threaded hole. The third connecting hole 230 can be configured to be a countersunk hole. The locking member 300 can be configured to be a locking screw. The top member 500 can be configured to be an anti-loosening wedge (an anti-loosening wedge refers to an object that is thick at one end and sharp at the other end and is used to fill the gap of an object to make it firm, such as a small wooden peg). In other embodiments, the locking member 300 can also be configured to be a latch, an expansion bolt or other locking structure.

[0041] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, further, the card slot 410 has an escape opening 411, and the escape opening 411 is along the width direction of the second handle 400 (such as Figure 2 The first side wall 221 and the second side wall 412 are located in the same plane and are in contact with the top tightening member 500. In this way, the side wall of the filling groove 220 close to the avoidance opening 411 and the side wall of the card slot 410 close to the avoidance opening 411 can both serve as the limiting surface of the top tightening member 500, ensuring that the top tightening member 500 can squeeze the clamping portion 210 to deform, and the deformed clamping portion 210 can simultaneously clamp multiple surfaces of the clamping groove 410, thereby improving the reliability of the handle structure 10.

[0042] like Figure 7 and Figure 8 As shown, optionally, along the vertical direction, the cross section of the filling groove 220 is set to be a right-angled trapezoid, the inclined side wall of the filling groove 220 is located on the side of the filling groove 220 away from the avoidance opening 411, and the width of the bottom of the filling groove 220 is greater than the width of the top of the filling groove 220. In this way, when the pressing member 500 is inserted into the filling groove 220, the inclined surface of the pressing member 500 will squeeze the inclined side wall of the filling groove 220, so that the clamping portion 210 is deformed so as to be able to press against multiple surfaces of the clamping groove 410 at the same time, thereby improving the reliability of the handle structure 10.

[0043] like Figure 3 , Figure 4 and Figure 8As shown, in one embodiment, there are two filling grooves 220, which are respectively located on both sides of the third connection hole 230, and the sides of the two filling grooves 220 that are away from each other extend to the two opposite outer side walls of the clamping portion 210, and the pressing member 500 is provided with two wedge-shaped portions 510 arranged at intervals, and the two wedge-shaped portions 510 are respectively inserted into the two filling grooves 220 when the second handle 400 is installed on the mounting member 200, so that the clamping portion 210 is deformed to press against the inner wall of the clamping groove 410. In this way, by increasing the number of wedge-shaped portions 510 and filling grooves 220, the pressing force of the pressing member 500 on the clamping portion 210 is more evenly distributed, the deformation amount of the clamping portion 210 is also more even, and it can press against multiple surfaces of the clamping groove 410 at the same time, thereby improving the reliability of the handle structure 10.

[0044] The number of the filling slots 220 and the wedge-shaped portions 510 can be flexibly adjusted according to the actual use requirements. Specifically in this embodiment, the width of the bottom of the wedge-shaped portion 510 is greater than the width of the bottom of the filling slot 220, and the width of the top of the wedge-shaped portion 510 is less than the width of the bottom of the filling slot 220. The inclination of the inclined surface of the wedge-shaped portion 510 is adapted to the inclination of the inclined side wall of the filling slot 220, so that the inclined surface of the wedge-shaped portion 510 and the inclined side wall of the filling slot 220 maintain surface contact during the process of the wedge-shaped portion 510 being inserted into the filling slot 220.

[0045] like Figure 3 and Figure 8 As shown, further, the pressing member 500 is further provided with a first connection portion 520, the first connection portion 510 is connected to both the two wedge-shaped portions 510, and the bottom surface of the clamping portion 210 is further provided with a second connection portion 240, and when the two wedge-shaped portions 510 are respectively inserted into the two filling grooves 220, the first connection portion 520 is connected to the second connection portion 240. In this way, after the pressing member 500 is inserted into the filling groove 220, the pressing member 500 can be fixed on the clamping portion 210 through the first connection portion 520 and the second connection portion 240, so as to prevent the pressing member 500 from falling off from the clamping portion 210, thereby improving the reliability of the handle structure 10.

[0046] The first connection part 520 and the second connection part 240 can be connected by snapping, plugging, buckling, screwing or other methods. The number of the first connection part 520 and the second connection part 240 can be flexibly adjusted according to the actual needs. Specifically in this embodiment, there are two first connection parts 520 and two second connection parts 240, and the two first connection parts 520 are corresponding to the two wedge-shaped parts 510, and the two second connection parts 240 are corresponding to the two filling slots 220.

[0047] like Figure 4 and Figure 8As shown, optionally, the first connection part 520 is provided with a limiting hole 521, and the second connection part 240 includes two elastic buckles 241 arranged at intervals. When the two wedge-shaped parts 510 are respectively inserted into the two filling slots 220, the two elastic buckles 241 are both passed through the limiting holes 521 and are respectively clamped on the opposite sides of the limiting holes 521. In this way, when the top fastener 500 is inserted into the filling slot 220, the two elastic buckles 241 are deformed to pass through the limiting hole 521, and the two elastic buckles 241 can be respectively buckled and clamped on the opposite sides of the limiting hole 521, thereby improving the reliability and convenience of the handle structure 10.

[0048] like Figure 3 and Figure 8 As shown, in one embodiment, the handle structure 10 further includes a cover plate 600, which is located at the bottom of the card slot 410 and covers the bottom of the card slot 410. In this way, the cover plate 600 can close the card slot 410 and shield the top fastener 500 and the clamping portion 210 in the card slot 410. The handle structure 10 has no exposed parts, which avoids rust problems and improves the service life and aesthetics of the handle structure 10.

[0049] Specifically in this embodiment, the handle structure 10 further includes a connecting sleeve 700 for connecting a decoration, the connecting sleeve 700 is located in the card slot 410, and is sleeved on the outer side of the clamping portion 210. When the pressing member 500 is inserted into the filling slot 220, the clamping portion 210 presses against the connecting sleeve 700, and the connecting sleeve 700 presses against the inner wall of the card slot 410, and the cover plate 600 is detachably connected to the bottom of the connecting sleeve 700 to cover the bottom of the card slot 410.

[0050] like Figure 3 and Fig. 9 As shown, in one embodiment, a mounting groove 120 is provided at one end of the first handle 100 facing the body 20 to be installed, and a second connection hole 110 is provided at the bottom wall of the mounting groove 120. The handle structure 10 further includes a gasket 800, which is installed in the mounting groove 120 and is provided with a fourth connection hole 810 corresponding to the second connection hole 110. The locking member 300 sequentially passes through the third connection hole 230, the first connection hole and the fourth connection hole 810 and extends into the second connection hole 110 to lock and match the mounting member 200, the gasket 800 and the first handle 100. In this way, the gasket 800 can fill the gap between the first handle 100 and the body 20 to be installed, ensuring that the first handle 100 can be stably and reliably fixed on the body 20 to be installed, thereby improving the reliability of the handle structure 10.

[0051] Optionally, the gasket 800 is limitedly matched with the inner side wall of the mounting groove 120 along the circumferential direction of the second connection hole 110. In this way, relative rotation does not occur between the gasket 800 and the first handle 100. Specifically in this embodiment, the mounting groove 120 and the gasket 800 are both arranged in a square shape.

[0052] like Figure 3 and Fig. 9 As shown, optionally, a first bite portion 820 arranged around the axis of the fourth connection hole 810 is provided on one side of the gasket 800 close to the mounting member 200, and a second bite portion 250 arranged around the axis of the third connection hole 230 is provided on one side of the mounting member 200 close to the gasket 800, and the first bite portion 820 and the second bite portion 250 are engaged to limit the relative rotation between the mounting member 200 and the gasket 800. In this way, the engagement and limiting of the first bite portion 820 and the second bite portion 250 ensure that the first handle 100, the gasket 800 and the mounting member 200 will not rotate relative to each other during the installation of the first handle 100, which is convenient for the installation of the first handle 100, and can also ensure the accuracy of the subsequent installation position of the second handle 400, thereby improving the convenience and assembly efficiency of the handle structure 10.

[0053] The number of the first bite portion 820 and the number of the second bite portion 250 can be flexibly adjusted according to the actual use needs. Specifically in this embodiment, the first bite portion 820 is set as a first protrusion, and there are at least two first protrusions. Both sides of each first protrusion along the circumference of the fourth connection hole 810 are 45° to the axis of the fourth connection hole 810. The second bite portion 250 is set as a second protrusion, and there are at least two second protrusions. Both sides of each second protrusion along the circumference of the third connection hole 230 are 45° to the axis of the third connection hole 230. Each first protrusion is correspondingly engaged with each second protrusion.

[0054] like Figure 1 As shown, in one embodiment, a door leaf is provided, including a door body and the handle structure 10 in any of the above embodiments, and the door body is provided with a first connecting hole for installing the handle structure 10.

[0055] When installing the door leaf in the above embodiment, first, the first handle 100 and the mounting member 200 are placed on both sides of the door body respectively, and then the mounting member 200, the door body and the first handle 100 are locked as a whole by the locking member 300. Then, the second handle 400 is put on the mounting member 200 from top to bottom by using the clamping limit of the clamping groove 410 and the clamping part 210. The second handle 400 is in a loose state relative to the mounting member 200, but will not fall from the mounting member 200. Finally, the pressing member 500 is inserted into the filling groove 220 from bottom to top, so that the clamping part 210 is deformed, the gap between the clamping part 210 and the inner wall of the clamping groove 410 disappears, and the clamping part 210 presses against the inner wall of the clamping groove 410, ensuring that the second handle 400 is stably and reliably fixed on the mounting member 200, and the installation of the handle structure 10 is completed. The door leaf in the present application has at least the following advantages: 1. The second handle 400 is mounted on the mounting member 200 in a hanging manner, which can be operated by one person with both hands and installed in place in one time. 2. The second handle 400 and the mounting member 200 are fixed by a tightening member 500, which is simple and convenient to operate. 3. The deformed clamping portion 210 can be multi-facetedly squeezed with the second handle 400, with no gap between the two, and the whole is stable without shaking. 4. The second handle 400 and the mounting member 200 do not need to be fixed with tightening screws, and there is no problem of loose tightening screws and slipping of the handle hole. The handle structure 10 has a long service life and a low maintenance rate.

[0056] Among them, the door body can be a glass door, a wooden door, a metal door, or a plastic door.

[0057] In order to facilitate further understanding of the handle structure 10 in the present application, the following will be described in detail by taking one of the installation methods of the handle structure 10 on the door body as an example, which should not be construed as a limitation to the present application.

[0058] When assembling the handle structure 10, first, place the first handle 100 and the mounting member 200 on both sides of the door body respectively, and then lock the mounting member 200, the door body and the first handle 100 as a whole by using the locking member 300. Secondly, by using the clamping limit of the clamping slot 410 and the clamping portion 210, the second handle 400 is sleeved on the mounting member 200 from top to bottom, and the second handle 400 is in a loose state relative to the mounting member 200, but will not fall from the mounting member 200. Then, the pressing member 500 is inserted into the filling slot 220 from bottom to top, so that the clamping portion 210 is deformed, the gap between the clamping portion 210 and the inner wall of the clamping slot 410 disappears, and the clamping portion 210 presses against the inner wall of the clamping slot 410, ensuring that the second handle 400 is stably and reliably fixed on the mounting member 200. Then, the pressing member 500 is further inserted into the filling slot 220, so that the two elastic buckles 241 on the clamping portion 210 are deformed and pass through the limiting hole 521, and the two elastic buckles 241 are respectively buckled and clamped on the opposite sides of the limiting hole 521 to prevent the pressing member 500 from loosening. Finally, the cover plate 600 is installed at the bottom of the clamping slot 410 and covers the clamping slot 410, and the installation of the handle structure 10 is completed.
