[0034] In the description of this utility model, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0035] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0036] An embodiment of the present invention provides a hand support device, which is applied to a seat. The specific structure and function of the hand support device provided by the embodiment of the present invention will be further described below with reference to text and drawings.

[0037] Reference Figures 1 to 7According to the first embodiment of the present invention, a hand support device includes a housing 100, a rotating base 200, and a pitch support assembly 300. The housing 100 serves as the supporting foundation for the entire device and possesses sufficient strength and stability. The rotating base 200 is disposed above the housing 100 and is rotatably connected thereto, allowing the rotating base 200 to rotate freely in the horizontal direction to accommodate different user requirements for armrest position.

[0038] The pitch support assembly 300 includes a pitch seat 310, a clip 320, an elastic member 330, and a support pad 340. The support pad 340 is disposed on the upper side of the pitch seat 310 to support the user's elbow. The pitch seat 310 is disposed above the rotating seat 200 and is connected to the pitch rotation of the rotating seat 200. Rotating the pitch seat 310 can adjust the pitch angle of the support pad 340. The lower side of the pitch seat 310 is provided with a plurality of clip grooves 311 spaced apart along the rotation direction. The clip 320 is movably connected to the rotating seat 200 and located below the pitch seat 310. Its upper side is provided with latching teeth 321 that match the latching grooves 311. The elastic member 330 is disposed between the rotating seat 200 and the clip 320 and is typically a spring or other elastic element. It is configured to push the clip 320 upward so that the latching teeth 321 can engage with the latching grooves 311. When the angle of the tilt base 310 needs to be adjusted, the user only needs to gently rotate the tilt base 310 so that the latching tooth 321 disengages from the current engaging slot 311 and moves to a new engaging slot 311 as the tilt base 310 rotates. When the latching tooth 321 aligns with the new engaging slot 311, the elastic member 330 pushes the engaging member 320 upward, causing the latching tooth 321 to engage with the engaging slot 311 again, thereby fixing the angle of the tilt base 310.

[0039] It is understood that the support pad 340 is located above the tilt seat 310 and is typically made of a soft and elastic material, such as sponge or memory foam, to provide comfortable elbow support. By rotating the tilt seat 310 and adjusting its angle, the user can easily adjust the tilt of the support pad 340 to meet the elbow support needs in different working scenarios.

[0040] According to the hand support device provided in the embodiment of the first aspect of the present utility model, the rotating seat 200 can rotate relative to the shell 100, so that the armrest can be adjusted in the horizontal direction according to the actual needs of the user. The pitch support assembly 300 realizes the angle adjustment and fixation of the support pad 340 in the pitch direction through the pitch rotation of the pitch seat 310 and the snap fit of the clamping member 320 and the clamping groove 311. This not only meets the needs of different users for the horizontal angle of elbow support, but also further takes into account the different tilt angles that the user's elbow may present during work, thereby providing a more fitting and comfortable support effect. The hand support device provided in the embodiment of the present utility model can greatly improve the comfort and experience of the user when using the chair, effectively relieve the elbow and shoulder and neck fatigue caused by long-term work, and improve the user experience.

[0041] Reference Figure 4 and Figure 5 According to the hand support device provided by the embodiment of the first aspect of the present invention, a receiving groove 201 is provided on the upper side of the rotating seat 200, which not only provides an installation space for the clamping member 320 and the elastic member 330, but also effectively protects the clamping member 320 and the elastic member 330, avoiding interference and damage from the external environment.

[0042] It is understood that both the clip 320 and the elastic member 330 are located within the receiving slot 201. The clip 320 is connected to the rotating base 200 via a connecting structure such as a rotating shaft, and can move up and down within the receiving slot 201 under the push of the elastic member 330. When the tilt base 310 rotates to a certain angle, the latching teeth 321 on the clip 320 align with the latching slot 311 on the underside of the tilt base 310. At this time, the elastic member 330 pushes the clip 320 upward, causing the latching teeth 321 to snap into the latching slot 311, thereby securing the tilt base 310.

[0043] Reference Figures 4 to 7 According to the hand support device provided by the embodiment of the first aspect of the present invention, the snap-in slot 311 is designed as a one-way slot with its opening facing the rear side. The front side of the snap-in slot 311 is a blocking surface, and the rear side is an inclined transition surface. This enables the snap-in member 320 to firmly fix the angle of the pitch seat 310 after being snapped into the snap-in slot 311. At the same time, when the angle of the pitch seat 310 needs to be adjusted, the snap-in member 320 can also slide smoothly through different snap-in slots 311.

[0044] The tilt base 310 is provided with a reset block 312 and a separation block 313. The reset block 312 is located in front of the multiple engaging slots 311, and the separation block 313 is located behind the multiple engaging slots 311. The reset block 312 and the separation block 313 assist in the engagement and disengagement of the engaging member 320, making the pitch adjustment of the tilt base 310 more convenient and stable.

[0045] The front side of the clip 320 is provided with a separation tooth 322, which is used to cooperate with the separation groove 202 on the rotating base 200 to separate the clip 320 from the engagement groove 311. When the pitch base 310 rotates forward and tilts upward, the multiple engagement grooves 311 on the pitch base 310 slide over the engagement teeth 321 on the clip 320 from front to back, eventually causing the engagement teeth 321 to abut against the separation block 313. At this time, the separation block 313 pushes the engagement teeth 321, causing them to separate from the engagement groove 311, and the separation tooth 322 to engage the separation groove 202. In this way, the clip 320 is fixed in the position of the separation groove 202, remaining separated from the engagement groove 311, allowing the pitch base 310 to be freely adjusted forward.

[0046] When the user needs to reconnect the separated latching teeth 321 with the engaging grooves 311, the user only needs to rotate the tilt seat 310 backward. The multiple engaging grooves 311 on the tilt seat 310 will slide over the latching teeth 321 on the engaging member 320 from back to front, and finally make the latching teeth 321 abut against the reset block 312. The reset block 312 pushes the latching teeth 321, causing the separating teeth 322 to disengage from the separating grooves 202. At this time, the elastic member 330 pushes the engaging member 320 upward, causing the latching teeth 321 to reengage the engaging grooves 311 at the front of the tilt seat 310, thereby fixing the angle of the tilt seat 310 and making it easier for the user to adjust the pitch angle of the tilt seat 310 and the support pad 340.

[0047] Reference Figure 2 、 Figure 3 as well as Figure 6 According to the hand support device provided by the embodiment of the first aspect of the present invention, the underside of the pitch base 310 is designed with an arcuate groove 314 extending in the front-to-back direction. The curvature of the arcuate groove 314 matches the possible rotation range of the pitch base 310 relative to the rotating base 200. Furthermore, a limiter 210 is provided on the rotating base 200. The limiter 210 is configured to pass through the arcuate groove 314 on the underside of the pitch base 310. This not only allows the rotating base 200 to adjust the pitch angle relative to the pitch base 310 within a certain range, but also ensures the stability and reliability of the rotating base 200 during adjustment through the cooperation between the limiter 210 and the arcuate groove 314. When the user needs to adjust the pitch angle of the hand support device, they simply move the rotating base 200 and slide the limiter 210 along the arcuate groove 314 to the desired position, achieving stable support angle adjustment, thereby meeting the needs of different users or usage scenarios.

[0048] Reference Figure 2 、 Figure 3 as well as Figure 6According to the hand support device provided by the embodiment of the first aspect of the present utility model, two arc-shaped grooves 314 are provided at intervals on the lower side of the pitch seat 310. The arc-shaped grooves 314 are parallel and extend in the front-to-back direction. Two limiting members 210 are also provided on the rotating seat 200. The positions of the two limiting members 210 correspond to the two arc-shaped grooves 314 under the pitch seat 310. During installation, the two limiting members 210 are respectively inserted into the two arc-shaped grooves 314 to form a double limiting structure. Such a design not only enables the rotating seat 200 to slide more smoothly along the arc-shaped grooves 314 during the pitch adjustment process, avoiding shaking or instability caused by unilateral force, but also improves the load-bearing capacity and durability of the entire hand support device through double-point support. When adjusting the pitch angle of the hand support device, the user can feel a smoother and more stable operating experience, meeting the accuracy and stability requirements in different usage scenarios.

[0049] Reference Figure 4 and Figure 5 According to the hand support device provided by the embodiment of the first aspect of the present utility model, the lower end surface of the rotating seat 200 is designed to be a plane, and a plurality of gear slots 203 are provided on the plane. The plurality of gear slots 203 are arranged circumferentially at intervals along the rotation direction of the rotating seat 200, forming a series of optional fixed positions. In order to cooperate with these gear slots 203, a connecting seat 110 is provided at the upper end of the shell 100, and a telescopic column 120 that can be extended toward or away from the rotating seat 200 is installed on the connecting seat 110. The upper end of the telescopic column 120 is designed to be able to be clamped in any one of the gear slots 203 on the lower end surface of the rotating seat 200, thereby realizing the stable fixation of the rotating seat 200 at a specific angle.

[0050] When the user needs to adjust the angle of the hand support device, they simply rotate the tilt seat 310 or support pad 340. The shift slots 203 and the top of the telescopic column 120 generate a squeezing force, causing the telescopic column 120 to disengage from the current shift slot 203 and snap into the next shift slot 203. This not only provides a clear sense of shift position, allowing the user to easily and accurately adjust to the desired angle, but also ensures the stability and reliability of the hand support device during use through the tight fit between the telescopic column 120 and the shift slot 203.

[0051] Reference Figure 4 and Figure 5 According to the hand support device provided by the embodiment of the first aspect of the present invention, the connecting seat 110 is provided with at least two telescopic columns 120, and the two telescopic columns 120 are respectively inserted into the gear slots 203 at different positions, thereby ensuring the stability of the fixation.

[0052] Reference Figure 5 and Figure 6According to the hand support device provided by the embodiment of the first aspect of the present invention, the reset block 312 and the pitch seat 310 are an integrally formed structure, which is beneficial to enhancing the stability and reliability of the structure between the reset block 312 and the pitch seat 310.

[0053] Reference Figure 5 and Figure 6 According to the hand support device provided by the embodiment of the first aspect of the present invention, the separation block 313 and the pitch seat 310 are an integrally formed structure, which is beneficial to enhancing the stability and reliability of the structure between the separation block 313 and the pitch seat 310.

[0054] The seat provided in accordance with the embodiment of the second aspect of the present invention has all the beneficial effects of the embodiment of the first aspect of the present invention.
