DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0026] Reference Figure 1 As shown, an embodiment of an adjustable handle device of the present invention includes a power-assisting component and a sliding component. The user can use the power-assisting component to gain leverage, and the sliding component can adjust the position of the power-assisting component according to the different body shapes of the users to facilitate the user's power assistance and improve comfort during use.

[0027] Reference Figure 1-Figure 3 The sliding assembly includes a slide rail 1 and a slide seat 2 that can move along the slide rail 1. A pressing block 3 and an auxiliary assembly are arranged inside the slide seat 2, and the pressing block 3 can be attached to or separated from the slide rail 1 under the action of the auxiliary assembly. When the pressing block 3 abuts against the slide rail 1 under the push of the auxiliary assembly, the slide seat 2 and the slide rail 1 can be relatively fixed; when the pressing block 3 is separated from the slide rail 1 under the push of the auxiliary assembly, the slide seat 2 can move along the slide rail 1, so that the position of the slide seat 2 is easily adjusted.

[0028] Reference Figure 3-Figure 5 The auxiliary assembly includes a compression spring 41, a push rod 42 and a docking seat 43, which are sequentially arranged in the slide 2. A limit ring 421 is fixedly arranged on the outer wall of the push rod 42, and the limit ring 421 is arranged near one end of the compression spring 41, and the compression spring 41 is sleeved on the push rod 42. One end of the compression spring 41 abuts against the limit ring 421, and the other end abuts against the bottom wall of the pressure block 3 or the slide 2. In this embodiment, the compression spring 41 abuts against the pressure block 3.

[0029] Reference Figure 3-Figure 5, one end of the push rod 42 away from the compression spring 41 passes through the docking seat 43. The auxiliary component also includes a first handle 6 that cooperates with the docking piece, and the first handle 6 and the docking seat 43 are rotatably connected through a universal joint. The first handle 6 includes a first flange 61 located at the rotation connection, and the docking seat 43 includes a boss 431 that cooperates with the first flange 61. The above-mentioned universal joint includes the above-mentioned first flange 61 and boss 431. The first flange 61 and the boss 431 are connected by a fixing pin, so that the docking piece and the first handle 6 can be rotatably connected around the fixing pin. In order to maintain the force balance when the first handle 6 and the docking seat 43 rotate, the first flange 61 is symmetrically arranged about the center point of the end of the first handle 6, and similarly, the boss 431 is symmetrically arranged about the center of the end of the docking seat 43; the first flange 61 and the boss located on the same side are in contact with each other, and the fixing pin passes through the two first flanges 61 and the two bosses 431 to realize the rotation connection between the first handle 6 and the docking seat 43.

[0030] Reference Figure 3-Figure 5 , the free end of the first flange 61 can abut against the protruding end of the push rod 42, because the push rod 42 is arranged along the axis of the docking seat 43, so the boss 431 in this embodiment is located on the outside of the first flange 61. The first flange 61 can rotate relative to the boss 431 around the fixing pin. In order to reduce the resistance during rotation, the free end of the first flange 61 in this embodiment is arranged in an arc shape. In the process of the first flange 61 moving from the edge of the arc to its apex, the first flange 61 can push the push rod 42 to extend and retract into the docking seat 43. The push rod 42 can abut against the pressure block 3 under the drive of the first flange 61, and can push the pressure block 3 to continuously approach and contact the slide rail 1. When the apex of the first flange 61 abuts against the push rod 42, the pressure block 3 can abut against the slide rail 1 under the push of the push rod 42, thereby achieving the fixation of the slide seat 2 relative to the slide rail 1.

[0031] Reference Figure 3-Figure 5 When the push rod 42 continuously drives the pressure block 3 and the slide rail 1 to abut against each other under the push of the first flange 61, the limit ring 421 will apply pressure to the compression spring 41, so that the compression spring 41 is continuously compressed, thereby further increasing the abutment force between the pressure block 3 and the slide rail 1. When the position of the slide seat 2 needs to be changed, the first handle 6 is turned to make the first flange 61 move along its vertex toward the edge, so that the thrust applied by the first flange 61 on the push rod 42 is continuously reduced. At this time, the compression spring 41 can convert its own elastic force into a thrust to push the limit ring 421 and the push rod 42 to move, so as to assist the reset of the push rod 42.

[0032] Reference Figure 3-Figure 5The outer wall of the docking seat 43 is sleeved with an adjusting nut 5, and the adjusting nut 5 is threadedly connected to the slide seat 2, so that the position of the docking seat 43 can be changed by adjusting the nut 5. After a long time, the elasticity of the rear compression spring 41 decreases, and the docking seat 43 is driven to approach the limit ring 421 by rotating the adjusting nut 5 to maintain its performance.

[0033] In another embodiment, referring to Figure 7 , the auxiliary component includes a first compression spring 91 and a first push rod 92, and a first limiting ring 93 is arranged on the outer wall of the first push rod 92. The first compression spring 91 is sleeved on the first push rod 92, and one end of the first compression spring 91 can abut against the first limiting ring 93, and the other end of the first compression spring 91 abuts against the bottom wall of the pressure block 3 or the slide seat 2. In this embodiment, the compression spring 41 abuts against the pressure block 3. The auxiliary component also includes a second handle 94 for auxiliary locking, and the end of the second handle 94 is provided with a second flange 941, and the second flange 941 is rotatably connected to the extended end of the first push rod 92. In this embodiment, in order to facilitate the rotation of the second handle 94, the second flange 941 is arranged in an arc shape. In the process of the second flange 941 moving from the edge of the arc to its apex, the second flange 941 can push the first push rod 92 to retract into the slide seat 2. The first push rod 92 can abut against the pressure block 3 under the drive of the second flange 941, and can push the pressure block 3 to continuously approach and contact the slide rail 1. When the vertex of the second flange 941 abuts against the end surface of the slide seat 2 , the pressing block 3 can abut against the slide rail 1 under the push of the first push rod 92 , thereby achieving the fixation of the slide seat 2 relative to the slide rail 1 .

[0034] Reference Figure 3 One end of the pressing block 3 is integrally formed with a protrusion, which is located on the side close to the push rod 42 to facilitate the contact between the push rod 42 and the pressing block 3. At the same time, in order to improve the clamping force between the pressing block 3 and the slide rail 1, the end surface of the pressing block 3 is provided with a recessed portion in which the slide rail 1 can be embedded, so as to increase the contact area between the pressing block 3 and the slide rail 1 and improve the clamping force. When the clamping force between the slide rail 1 and the pressing block 3 is released, part of the slide rail 1 can still be embedded in the recessed portion, thereby limiting the direction of movement of the pressing block 3.

[0035] Reference Figure 3 A plurality of fixing hooks 21 capable of being embedded in the slide rail 1 are arranged on the slide seat 2. In this embodiment, the fixing hooks 21 are symmetrically arranged, and the embedding force between the fixing hooks 21 and the slide seat 2 can prevent the slide seat 2 and the slide rail 1 from being separated.

[0036] Reference Figure 3 and Figure 6The resistance assembly includes an auxiliary handle 7, one end of which is inserted into the interior of the slide 2 and can rotate relative to the slide 2; the handle 7 can be used and stored by rotating it to different positions. In addition, a locking assembly is also provided in the slide 2, which can fix the handle 7 after it is rotated to a desired position, thereby locking the state of the handle 7.

[0037] Reference Figure 3 and Figure 6 The locking assembly includes a locking member 8 and an elastic member 82. The locking member 8 can rotate relative to the slide 2. One end of the handle 7 inserted into the slide 2 is provided with a slot 72 that cooperates with the locking member 8. The locking member 8 and the slot 72 can be used to fix the handle 7 relative to the slide 2. One end of the elastic member 82 is connected to the free end of the locking member 8, and the other end is fixed to the slide 2. In this embodiment, the elastic member 82 is preferably a coil spring.

[0038] Reference Figure 3 and Figure 6 The card slot 72 includes a first card slot 72 and a second card slot 72, and both the first card slot 72 and the second card slot 72 can be engaged with the locking member 8. In this embodiment, when the locking member 8 is embedded in the first card slot 72, the handle 7 is in a stored state; when the locking member 8 is embedded in the second card slot 72, the handle 7 is in a used state. However, this solution does not exclude the provision of more card slots 72 according to actual needs to achieve locking of the handle 7 in different states.

[0039] Reference Figure 3 and Figure 6 , the middle part of the locking member 8 is connected to the slide 2 through the flip switch 81. In the initial state, the locking member 8 is embedded in the first slot 72, and then the locking member 8 is rotated by the flip switch 81, so that the locking member 8 is disengaged from the first slot 72, and the elastic member 82 is in a compressed state; then the handle 7 is pulled to the use state, and the locking member 8 is rotated by the flip switch 81, so that the locking member 8 can be embedded in the second slot 72, thereby locking the handle 7 in the use state. At the same time, the elastic member 82 can convert its own elastic force into a thrust to push the locking member 8 to move, so as to facilitate the reset of the locking member 8.

[0040] Reference Figure 3 and Figure 6, when the end of the handle 7 is embedded in the inside of the slide 2 and rotates, in order to prevent the handle 7 from being separated from the slide 2, a limit plate 71 is sleeved on the handle 7. In order to facilitate installation, the handle in this embodiment is spliced ​​in sections, that is, the handle includes a first section and a second section that is detachably fixed to the first section. In this embodiment, the part inserted in the slide 2 is set as the first section, and the part located outside the slide 2 is set as the second section. During the installation process, the first section is first inserted into the slide 2, and then the limit plate 71 is embedded in the end of the first section close to the opening of the slide 2, and then the second section is connected to the first section.
