[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation, connection and connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] A handle and an installation method thereof according to an embodiment of the present invention are described below with reference to the accompanying drawings.

[0042] Reference Figures 1 to 3 The present invention aims to provide an embodiment of a handle, which is used to be installed on a door panel 250.

[0043] In this embodiment, the door panel 250 is the installation object of the handle, and can be a protective door of equipment, a door or window of a building, etc.

[0044] In this embodiment, the handle mainly includes a handle body 100 . The handle body 100 is in an arch shape, so that a gap is formed between the handle and the door panel 250 , which is convenient for a person to reach in and hold the handle body 100 .

[0045] In some specific embodiments of the present invention, the handle may include a cover 260. The cover 260 may be formed by injection molding to facilitate the formation of a snap-fit ​​buckle. The snap-fit ​​buckle may be deformed, so that the snap-fit ​​buckle connects the cover 260 and the handle body 100, thereby reducing the use of screws, and reducing assembly operations and assembly costs.

[0046] In some specific embodiments of the present invention, the snap-fit ​​buckles can be arranged side by side. Figure 3 The two ends of the middle cover 260 can also be arranged in a column shape, referring to Figure 2 The arrangement of the middle portion of the middle cover 260 can be implemented in various forms.

[0047] In some specific embodiments of the present invention, a gap can be formed between the handle body 100 and the cover 260 to reduce the entity, reduce weight and cost, and reserve space for arranging various structures, such as the return spring 200 and the control shaft 170.

[0048] In this embodiment, the handle also includes a knob 110, which is rotatably connected to the handle body 100. The outer contour of the surface of the knob 110 for fitting the door panel 250 is non-circular relative to the rotation center of the knob 110, and the knob 110 has a first state and a second state.

[0049] In the first state, the knob 110 can pass through the opening on the door panel 250 , so that the knob 110 and the handle body 100 are located on both sides of the door panel 250 .

[0050] In the second state, the knob 110 can abut against the door panel 250 , so that the knob 110 and the handle body 100 clamp the door panel 250 to complete the installation.

[0051] In this embodiment, the cross-section of the knob 110 is rectangular. Therefore, when the knob 110 is rotated 90°, both ends of the knob 110 in the length direction will press on the entity of the door panel 250 to prevent the handle from separating from the door panel 250.

[0052] With regard to the understanding that the outer contour of the surface of the knob 110 for fitting the door panel 250 is not a perfect circle relative to the rotation center of the knob 110, it can be considered that when the knob 110 rotates, the area covered by the knob 110 will change, thereby enabling the knob 110 to be pressed against the door panel 250 entity to complete the installation.

[0053] When the surface of the knob 110 for fitting the door panel 250 is circular, and the center of the circle coincides with the rotation center of the knob 110, when the knob 110 is rotated, the knob 110 is still located in the area surrounded by the opening on the door panel 250, which cannot meet the installation requirements.

[0054] In some specific embodiments of the present invention, the surface of the knob 110 for fitting the door panel 250 can be an ellipse or a polygon. The polygon includes a triangle, rectangle, square, parallelogram, rhombus, pentagon, hexagon and more sides, which can meet the installation requirements, but will increase the manufacturing difficulty and needs to be reasonably determined.

[0055] In some specific embodiments of the present invention, the surface of the knob 110 for contacting the door panel 250 may be circular, but the center of the circle does not coincide with the rotation center of the knob 110 , which can also meet the installation requirements.

[0056] In some specific embodiments of the present invention, the surface of the knob 110 for fitting the door panel 250 can be the axial projection of the gear, which can also meet the installation requirements, but the manufacturing cost is high and there are strict restrictions on the shape of the opening on the door panel 250.

[0057] In some specific embodiments of the present invention, knobs 110 may be provided at both ends of the handle body 100 so that the installation methods of the two ends of the handle are the same, thereby reducing the specifications of components.

[0058] In some specific embodiments of the present invention, a knob 110 may be provided at one end of the handle body 100, and a buckle 210 may be provided at the other end of the handle body 100, thereby reducing the number of knobs 110. Meanwhile, the buckle 210 is directly inserted and installed without rotating the knob 110, thereby further simplifying the operation.

[0059] The present invention sets the knob 110, so when installing the handle, the knob 110 can be passed through the opening on the door panel 250, and then the knob 110 is rotated so that the knob 110 presses the door panel 250 to complete the installation of the handle, simplifying the installation operation and allowing the handle to be installed quickly and conveniently.

[0060] In some specific embodiments of the present invention, the end of the handle body 100 can be inserted into the opening of the door panel 250 to reduce the gap between the handle body 100 and the opening of the door panel 250 and prevent the handle body 100 from moving along the door panel 250 .

[0061] In some specific embodiments of the present invention, the knob 110 may have a flat portion for manual turning and rotation, making it easier for manual force to be applied.

[0062] In some specific embodiments of the present invention, the knob 110 can be rotatably connected to the handle body 100 via the mounting member 120 .

[0063] Specifically, the mounting member 120 includes a rotating shaft 130 penetrating the handle body 100 , one end of the rotating shaft 130 is provided with a radial protrusion 140 for preventing from falling off, and the other end of the rotating shaft 130 is used for connecting with the knob 110 .

[0064] The handle body 100 may be provided with a mounting hole for accommodating the rotation of the shaft 130 , so that the shaft 130 of the mounting member 120 moves from the axial direction of the mounting hole toward the knob 110 , and then the shaft 130 is connected to the knob 110 , and the knob 110 is rotationally connected to the handle body 100 .

[0065] In some specific embodiments of the present invention, the radial protrusion 140 may be an outwardly convex ring to improve the matching strength with the handle body 100 and prevent the mounting member 120 from coming off and causing the knob 110 to separate from the handle body 100 .

[0066] In some specific embodiments of the present invention, the mounting hole can be made into a semi-enclosed shape, so that the mounting member 120 can be installed radially along the mounting hole. Furthermore, the knob 110 can be manufactured integrally with the mounting member 120, such as by casting, to reduce the number of parts.

[0067] To facilitate the connection between the shaft 130 and the knob 110 , the shaft 130 can be inserted into the knob 110 . The knob 110 is provided with a set screw 150 , and the end of the set screw 150 is used to abut against the radial outer surface of the shaft 130 to fix the shaft 130 and the knob 110 .

[0068] It is easy to understand that this embodiment can not only meet the connection between the rotating shaft 130 and the knob 110, but also can adjust the depth of the rotating shaft 130 inserted into the knob 110, that is, make the fixing screw 150 abut against different axial positions of the rotating shaft 130, thereby changing the distance or gap between the knob 110 and the handle body 100 to adapt to door panels 250 of different thicknesses.

[0069] In some specific embodiments of the present invention, the mounting member 120 may be replaced so that the length of the rotating shaft 130 of the mounting member 120 is different to overcome the great difference in the thickness of the door panel 250 .

[0070] In this embodiment, there are two set screws 150 , and the two set screws 150 abut against and clamp the rotating shaft 130 .

[0071] It is easy to understand that, in this embodiment, by providing two set screws 150 , it is possible to increase the locking points, improve the locking reliability, increase the bearing strength, and prevent the knob 110 from separating from the mounting member 120 .

[0072] In some specific embodiments of the present invention, the two set screws 150 can be distributed on both sides of the width direction of the knob 110, or in other words, the two set screws 150 are located on the two long sides of the knob 110, which is beneficial to shortening the length of the set screws 150 and the depth of the corresponding hole, thereby reducing the manufacturing cost.

[0073] In some specific embodiments of the present invention, the radial outer surface of the rotating shaft 130 can have a rough portion 160, and the rough portion 160 is used to abut the end of the locking screw 150 to increase the friction between the locking screw 150 and the rotating shaft 130 and improve the bearing capacity. The bearing capacity is used to resist the force or tendency of pulling the handle to drive the door panel 250 to move and separate the knob 110 from the rotating shaft 130.

[0074] In some specific embodiments of the present invention, the rough portion 160 may include a knurled surface to reduce the difficulty of forming the rough portion 160 .

[0075] In some specific embodiments of the present invention, the rough portion 160 may include a rack shape, so that the set screw 150 is inserted into the tooth groove to limit the axial movement of the rotating shaft 130 .

[0076] In some specific embodiments of the present invention, the rough portion 160 may be a plane to increase the contact with the set screw 150 .

[0077] Since the rotating shaft 130 needs to pass through the mounting hole of the handle body 100 and the rotating shaft 130 realizes the rotational connection between the knob 110 and the handle body 100, the cross-section of the rotating shaft 130 has a circular profile matching the mounting hole. At the same time, since the rough portion 160 is provided, the cross-section of the rotating shaft 130 is not a full circle, or a section of the rotating shaft 130 used to match the mounting hole is a full circle, while a section of the rotating shaft 130 used to match the set screw 150 is not a full circle, so as to meet the need of providing the rough portion 160.

[0078] In order to prevent the knob 110 from accidentally rotating and causing the handle to loosen, the handle includes a rotation control assembly, and the rotation control assembly includes a control shaft 170 .

[0079] In this embodiment, one end of the control shaft 170 is slidably connected to the knob 110, and the other end of the control shaft 170 is passed through the handle body 100. One of the handle body 100 and the control shaft 170 is provided with a limiting protrusion 190, and the other of the handle body 100 and the control shaft 170 is provided with a limiting recess 180. When the control shaft 170 moves along its own axis, the limiting protrusion 190 and the limiting recess 180 can be engaged with or staggered with each other, and the limiting protrusion 190 and the limiting recess 180 are engaged with each other to prevent the knob 110 from rotating.

[0080] In some specific embodiments of the present invention, since the mounting member 120 and the knob 110 are relatively fixed, the control shaft 170 can also be slidably connected to the mounting member 120, and the rotation of the knob 110 can also be controlled.

[0081] In some specific embodiments of the present invention, one end of the control shaft 170 can be slidably connected to the handle body 100, and the other end of the control shaft 170 is inserted into the knob 110. A limiting protrusion 190 is provided on one of the knob 110 and the control shaft 170, and a limiting recess 180 is provided on the other of the knob 110 and the control shaft 170. When the control shaft 170 moves along its own axis, the limiting protrusion 190 and the limiting recess 180 can be engaged with or staggered with each other, and the limiting protrusion 190 and the limiting recess 180 are engaged with each other to prevent the knob 110 from rotating.

[0082] Therefore, for the control of rotation, the structures among the knob 110 , the control shaft 170 and the handle body 100 may be reversed to achieve the same effect.

[0083] As for the limiting recess 180 and the limiting protrusion 190 , the limiting recess 180 and the limiting protrusion 190 can be located in the radial direction of the control shaft 170 to facilitate limiting the rotation.

[0084] In some specific embodiments of the present invention, the limiting recess 180 and the limiting protrusion 190 can be located in the axial direction of the control shaft 170, but the limiting recess 180 and the limiting protrusion 190 are required to deviate from the rotation center of the knob 110, or the limiting recess 180 and the limiting protrusion 190 have a solid part that deviates from the rotation center of the knob 110.

[0085] In this embodiment, the limiting recess 180 is arranged on the handle body 100, and the limiting protrusion 190 is arranged at the end of the control shaft 170 to reduce the manufacturing difficulty and reduce the manufacturing cost. At the same time, the structure is reasonable and reliable. Moreover, the limiting protrusion 190 is arranged at the end of the control shaft 170, which is also convenient for connecting the return spring 200.

[0086] The rotation control assembly includes a return spring 200, which is used to drive the control shaft 170 to move so that the limiting protrusion 190 and the limiting recess 180 can engage with each other, thereby keeping the control shaft 170 in a state of preventing rotation.

[0087] In some specific embodiments of the present invention, the cover 260 may be provided with a positioning column to position the end of the return spring 200 away from the control shaft 170 to facilitate the return spring 200 to apply force.

[0088] In some specific embodiments of the present invention, the control shaft 170 may pass through the knob 110 and protrude to the outside of the knob 110 , so that a person can press the control shaft 170 to operate it.

[0089] In some specific embodiments of the present invention, the handle may include a rotating shaft 130 , which is used to rotatably connect the knob 110 to the handle body 100 . The rotating shaft 130 is hollow and is sleeved on the outside of the control shaft 170 .

[0090] Therefore, the control shaft 170 can be pressed to make the limiting concave portion 180 and the limiting convex portion 190 staggered or separated, and the knob 110 and the control shaft 170 do not need to be separated, which also reduces the difficulty of returning the control shaft 170.

[0091] At the same time, the rotating shaft 130 is hollow and is sleeved on the outside of the control shaft 170 , which is also beneficial to reducing the space occupied by the rotating shaft 130 in the radial direction.

[0092] As for the buckle 210 , the buckle 210 may be welded to the handle body 100 to reduce the number of parts.

[0093] In some specific embodiments of the present invention, the buckle 210 can be a detachable elastic member with high deformation ability for easy installation.

[0094] Reference Figure 2In some specific embodiments of the present invention, the handle body 100 may be provided with an adjustment rod 220, which is used to adjust the gap between the buckle 210 and the handle body 100. The adjustment rod 220 includes a threaded portion 230 connected to the handle body 100 and a rotating connection portion 240 connected to the buckle 210.

[0095] In some specific embodiments of the present invention, a nut may be welded to the handle body 100 , and the nut may be screwed together with the threaded portion 230 , thereby reducing manufacturing difficulty.

[0096] In some specific embodiments of the present invention, the adjusting rod 220 can be a bolt, the screw section of the bolt passes through the buckle 210, and the screw section of the bolt is fitted with another nut, which cooperates with the head of the bolt to clamp the buckle 210, and the rotating connection part 240 is formed by the cooperation of the nut and the head of the bolt.

[0097] Reference Figure 4 The present invention also aims to provide an embodiment of a handle installation method, which can be applied to the installation of the above-mentioned handle. The handle installation method mainly includes: passing the knob 110 through the opening of the door panel 250, rotating the knob 110 so that the knob 110 is offset from the opening of the door panel 250, and pressing the knob 110 against the door panel 250 to complete the installation.

[0098] In summary, the present invention can simplify the operation of installing the handle by applying the above handle, so that the handle can be installed quickly and conveniently.

[0099] For reference Figures 1 to 3 The handle of the present invention, the handle installation method is as follows: In the gap adjustment step S100, the adjustment rod 220 is rotated so that the gap between the buckle 210 and the handle body 100 matches the thickness of the door panel 250, the set screw 150 is loosened so that the gap between the knob 110 and the handle body 100 matches the thickness of the door panel 250, and then the set screw 150 is locked.

[0100] In the buckle installation step S200 , the edge of the buckle 210 is inserted into the opening of the door panel 250 , and the handle body 100 is rotated so that the buckle 210 passes through the opening of the door panel 250 , and at the same time, the knob 110 passes through another opening of the door panel 250 .

[0101] In some specific embodiments of the present invention, when the handle body 100 is rotated, the portion of the handle body 100 where the buckle 210 is provided may be pressed simultaneously, so as to facilitate the buckle 210 to be locked into the door panel 250 .

[0102] In the knob installation step S300, both ends of the handle body 100 are placed against the door panel 250, and the end of the control shaft 170 is pressed to move the control shaft 170 so that the limiting protrusion 190 and the limiting recess 180 are offset. The knob 110 is rotated so that the knob 110 is pressed against the door panel 250. Then, the control shaft 170 is released, and the reset spring 200 drives the control shaft 170 to move so that the limiting protrusion 190 and the limiting recess 180 are re-engaged.

[0103] In summary, the present invention provides the buckle 210 , so that the buckle 210 can be first inserted into the opening of the door panel 250 , and then the buckle 210 can be rotated to complete the installation of the buckle 210 , which is convenient and quick.

[0104] The present invention sets an adjustment rod 220, so that the threaded portion 230 of the adjustment rod 220 can engage the handle body 100 at different positions by rotating the adjustment rod 220, thereby changing the gap between the buckle 210 and the handle body 100 to adapt to door panels 250 of different thicknesses.

[0105] The present invention can also utilize the elasticity of the buckle 210 itself, so that the buckle 210 and the handle body 100 elastically clamp the door panel 250 to reduce looseness.

[0106] The present invention sets the knob 110, so when the knob 110 passes through another opening of the door panel 250, the knob 110 is rotated so that the knob 110 presses the door panel 250 to complete the installation of the knob 110, thereby realizing the quick installation of the handle, which is convenient and quick.

[0107] In the present invention, the mounting member 120 is provided so that the mounting member 120 has a rotating shaft 130 , thereby realizing the rotation connection between the knob 110 and the handle body 100 .

[0108] The present invention provides the radial protrusion 140 so that the radial protrusion 140 abuts against the handle body 100 , thereby preventing the mounting member 120 from coming off the handle body 100 and ensuring that the knob 110 is reliably rotatably connected to the handle body 100 .

[0109] The present invention sets a set screw 150, so that by loosening the set screw 150, the position of the knob 110 can be adjusted, and the gap between the knob 110 and the handle body 100 can be changed to adapt to door panels 250 of different thicknesses. By locking the set screw 150, the distance between the knob 110 and the handle body 100 is fixed, which facilitates clamping the door panel 250.

[0110] The present invention sets a control shaft 170 so that the control shaft 170 is slidably connected to the knob 110, so that the control shaft 170 and the knob 110 rotate synchronously. Furthermore, by limiting the control shaft 170, the knob 110 can be prevented from accidentally rotating and loosening or causing the handle to loosen.

[0111] The present invention provides the limiting protrusion 190 and the limiting recess 180 , so that when the limiting protrusion 190 and the limiting recess 180 are engaged, the knob 110 can be prevented from rotating.

[0112] The present invention provides a return spring 200 , so that the return spring 200 drives the control shaft 170 to move along its own axial direction, so that the limiting protrusion 190 and the limiting recess 180 are in a locked state and maintain the locked state, thereby preventing the control shaft 170 from rotating.

[0113] The present invention enables the control shaft 170 to pass through the knob 110 and protrude to the outside of the knob 110. Therefore, by pressing the end of the control shaft 170, the elastic force of the return spring 200 is resisted, so that the control shaft 170 moves in the opposite direction, and then the limiting protrusion 190 and the limiting recess 180 are separated or offset, and then the rotation restriction of the control shaft 170 is released, so that the knob 110 can rotate to meet the installation requirements.
