Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of antistatic stools, specifically to a combined antistatic stool. Background Technology
[0002] In electrostatic-sensitive work environments such as electronics manufacturing and laboratories, anti-static stools are crucial for ensuring equipment safety and protecting operators. Publication number CN219845767U discloses an anti-static laboratory stool, including a seat and legs mounted on the seat. An insulating layer is detachably mounted on the seat, and a positioning mechanism is provided for positioning the insulating layer. The positioning mechanism includes a sub-Hook and loop fastener, a female hook and loop fastener, and a positioning component. The sub-Hook and loop fastener is detachably mounted on the seat; the female hook and loop fastener is mounted on the insulating layer and can be adhesively connected to the sub-Hook and loop fastener for positioning the insulating layer; the positioning component is mounted on the seat and is used to position the sub-Hook and loop fastener. This application reduces the probability of static electricity accumulation on the seat, thereby reducing the probability of workers suffering discomfort due to static electricity, thus improving the comfort of the stool.
[0003] However, the existing anti-static test bench has the following problems: 1. The components of the existing anti-static test bench are connected by fastening or integrated design. When one component is damaged, the whole bench needs to be replaced.

The grounding structure of the existing anti-static test bench mostly uses a single contact point or wire connection. With long-term use, wear and oxidation can easily lead to a decrease in conductivity stability, resulting in poor grounding conductivity and poor anti-static effect. Utility Model Content

The antistatic grounding structure 7 is used to ensure the stability of the grounding wire and the antistatic effect.
[0028] The lifting mechanism 4 includes a pneumatic rod, which comprises a fixed rod, a movable rod, a lifting assembly, and a control assembly. The fixed rod has a sliding cavity, and the lifting assembly is disposed within the sliding cavity. The movable rod is connected to the lifting assembly and disposed within the fixed rod, and the movable rod can rise or fall along the sliding cavity seat via the lifting assembly. The movable rod has a cavity, and the control assembly is disposed within the cavity. The control assembly includes a control valve, which has an operating handle 40. The lifting mechanism 4 is used to adjust the height of the stool seat 2, forming a combination anti-static stool 1 of different heights, thereby improving its usability.
[0029] The top of the movable rod and the bottom of the fixed rod are both provided with connecting seats 41. The stool base 2 and the stool frame 3 are both provided with first connecting seats 8. The connecting seats 41 are both provided with grooves 410. The snap-fit connection structure 6 includes a snap-fit structure 60 and a snap-hole structure 61. The snap-fit structure 60 is disposed on the first connecting seat 8, and the snap-hole structure 61 is disposed on the connecting seat 41. The snap-fit structure 60 is used to snap-fit with the snap-hole structure 61 during assembly. The snap-fit structure 60 includes multiple elastic hooks arranged in a circular array on the first connecting seat 8; the snap-hole structure 61 includes multiple snap-holes arranged in a circular array on the outer wall of the connecting seat 41. The hooks are connected to the snap-holes through the grooves 410. The snap-fit connection structure enables detachable assembly and disassembly between the stool seat 2 and the lifting mechanism 4, and between the lifting mechanism 4 and the stool legs 5, improving the efficiency of assembly or disassembly and facilitating the maintenance and replacement of individual components. When the stool seat 2, the lifting mechanism 4, or the stool frame 3 malfunctions or is damaged, individual components can be disassembled and replaced without replacing the entire modular anti-static stool 1, thus reducing maintenance and repair costs.
[0030] Each groove 410 has a positioning post 410a at its center, and each of the first connecting seats 8 has a positioning hole 80 that cooperates with the positioning post 410a. The positioning post 410a is used for positioning connection with the positioning hole 80 during assembly.

Furthermore, this invention employs an anti-static grounding structure composed of an outer and inner contact structure to ensure stable grounding contact between the stool seat and the lifting mechanism, and between the lifting mechanism and the stool legs. This increases the grounding contact area during connection, ensuring subsequent grounding conductivity and guaranteeing anti-static performance. Additionally, springs and two contact plates ensure a tight fit between the support rod and the legs, guaranteeing the effectiveness of the subsequent grounding wire and ensuring anti-static performance.
