[0001] This utility model relates to the field of chair technology, and in particular to an antistatic chair seat and chair. Background Technology

[0002] Currently, common anti-static chairs mainly suppress static electricity by installing a layer of anti-static material on the base plate. However, existing anti-static chairs only have anti-static material on the seat surface. When users move the chair, they inevitably come into contact with the edge of the seat surface. Since the edge of the seat is not covered with anti-static material, the overall anti-static effect of the chair is defective and cannot meet the requirements of comprehensive anti-static. At the same time, the backrest spacing of the chair is fixed and cannot be flexibly adjusted according to the different body characteristics of different users and changes in usage scenarios. This greatly limits its applicability and makes it difficult to meet the needs of a variety of people. Utility Model Content

[0026] Please see Figures 1-2In this embodiment of the present invention, an antistatic chair seat includes a seat cushion 1, an L-shaped rod 2, and a backrest 3. One end of the L-shaped rod 2 is fitted with the backrest 3, and the other end is slidably connected to the lower end face of the seat cushion 1. A sliding groove 11 for sliding the L-shaped rod 2 is provided on the upper end face of the seat cushion 1 near the L-shaped rod 2. The opening size of the sliding groove 11 is not less than the diameter of the L-shaped rod 2. The seat cushion 1 includes a base plate 12, an antistatic pad 13, and a seat cushion 14. The antistatic pad 13 is installed on the upper end of the base plate 12, and the seat cushion 14 is laid on the upper end face of the antistatic pad 13. The base plate 12 is provided with an antistatic edging sleeve 16, which is fitted onto the edge of the base plate 12. Specifically, the installation methods between the L-shaped plate and the backrest 3 include, but are not limited to, threaded connections, snap-fit ​​connections, tenon and mortise connections, or adhesive bonding. The antistatic pad 13 and the antistatic edging sleeve 16 can be made of conductive polyurethane material or antistatic PU leather. Conductive polyurethane material has good wear resistance and antistatic effect. Its low surface resistivity effectively prevents static electricity accumulation, while the material itself has high mechanical strength and wear resistance, making it suitable for chair surfaces. PU leather is a commonly used antistatic material with good wear resistance, softness, and comfort. Its surface resistivity is typically between 10^6 and 10^9 ohms, effectively preventing static electricity accumulation. The working principle of this embodiment: By setting an antistatic edging sleeve 16 at the edge of the base plate 12, static electricity can be avoided at the edge of the seat, making the overall antistatic effect of the antistatic chair more complete and better meeting the requirements of antistatic protection. Simultaneously, the spacing of the backrest 3 is adjustable, driving the L-shaped rod 2 to slide towards the sliding groove 11. The L-shaped rod 2 can slide into the sliding groove 11, and the sliding of the L-shaped rod 2 allows for flexible adjustment of the backrest 3 spacing to meet the needs of different users, improving applicability and satisfying the needs of more people.

[0027] Further as Figures 3-4As shown in this embodiment of the invention, a groove 15 is provided on the lower end face of the cushion 1, which connects to a sliding groove 11. An L-shaped rod 2 has a slider 21, which is slidably installed within the groove 15. The rear side of the slider 21 is connected to the L-shaped rod 2. Several locking grooves 151 are provided on the left and right edges of the groove 15. The slider 21 has at least two eccentric locking rods 22, which are hinged to the lower end face of the slider 21. The size of the locking groove 151 is not less than the diameter of the eccentric locking rod 22. The eccentric locking rod 22 includes an eccentric wheel 221 and a first handle 222. The eccentric wheel 221 is hinged to the lower end face of the slider 21, and one end of the first handle 222 is connected to the eccentric wheel 221 to drive its rotation. Specifically, the connection between the L-shaped rod 2 and the slider 21 includes, but is not limited to, threaded connection, snap-fit ​​connection, or adhesive connection. The size of the slot 151 is not less than the thickness of the eccentric wheel 221, so that the eccentric wheel 221 can be locked in the slot 151, thereby restricting the eccentric wheel 221. For example, when the eccentric wheel 221 is locked in the slot 151, the slider 21 cannot continue to slide in the direction of the sliding groove 15, and the distance between the backrests 3 cannot be adjusted. The working principle of this embodiment is as follows: the user drives the slider 21 to slide by hand, which causes the L-shaped rod 2 connected to one end of the slider 21 to slide together with the slider 21. The backrest 3 installed on the L-shaped rod 2 will also slide along the sliding direction of the slider 21 with the L-shaped block. The L-shaped rod 2 can slide into the sliding groove 11 to adjust the distance between the backrests 3.

[0028] like Figure 4 As shown, in another embodiment of this utility model, the operator first drives the slider 21 to slide, aligning the eccentric wheel 221 with the locking groove 151. Then, by rotating the first handle 222, the operator can drive the eccentric wheel 221 to rotate. As the eccentric wheel 221 rotates, its radius gradually increases, resulting in a stronger pressing force on the slider 21. Simultaneously, after rotation, the eccentric wheel 221 locks itself in the locking groove 151, restricting the position of the eccentric locking rod 22 and preventing the slider 21 from sliding. The backrest 3's spacing is then locked and cannot be adjusted. Conversely, by rotating the first handle 222 in the opposite direction, the operator causes the eccentric wheel 221 to rotate out of the locking groove 151, and the pressing force on the slider 21 gradually decreases. At this point, the slider 21 can slide, allowing for continued adjustment of the backrest 3's spacing. This solution enables the adjustment of different backrest spacings to meet the needs of different users.

[0029] Further as Figures 4-5As shown in the embodiment of this utility model, the eccentric wheel 221 and the first handle 222 are integrally formed. The eccentric wheel 221 and the first handle 222 can be formed by casting or by machining. The material of the eccentric wheel 221 and the first handle 222 can be steel, iron, or cast iron, etc.

[0030] Further as Figures 3-5 As shown in this embodiment of the invention, three locking slots 151 are provided at equal intervals on the left and right edges of the slide groove 15. These three locking slots 151 serve as the three adjustable positions of the backrest 3, allowing it to cover the body shape of most people. The double-sided locking slots 151 design ensures balanced pressure on both sides when the slider 21 is locked.

[0031] Further as Figures 1-2 As shown in the embodiment of this utility model, the surface of the seat cushion 14 and the surface of the backrest 3 are provided with anti-slip textures. Specifically, the surfaces of the seat cushion 14 and the backrest 3 are provided with diamond-shaped raised anti-slip textures (height 1-2mm, spacing 5mm), which increases the friction by increasing the roughness of the contact surface and prevents the staff from sliding on the seat. The anti-slip textures can also adopt a hard anti-slip structure, such as rubber particles attached to the surface, which can improve the comfort of sitting.

[0032] Further as Figures 4-5 As shown in this embodiment of the invention, the slider 21 is provided with a second handle 211, which is detachably mounted on the rear end face of the slider 21. The surface of the second handle 211 is provided with anti-slip texture. The connection between the second handle 211 and the slider 21 includes, but is not limited to, threaded connection or snap-fit ​​connection, which facilitates the user to grip the second handle 211 to slide the slider 21. The anti-slip texture on the grip surface prevents slippage during gripping, increases the friction with the hand, and facilitates a firm grip on the second handle 211.

[0033] In another embodiment of the present invention, an antistatic chair includes the aforementioned antistatic chair seat.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
