Description

Technical Field

[0001] The utility model relates to the technical field of screws, in particular to a cap screw. Background Art

[0002] "Screw" is a common fastener, also known as a screw or bolt, used to connect or fix two or more objects. It usually consists of a head and a screw (a rod with threads). Screws are widely used in daily life and industrial production. For example, screws can be seen in furniture, machines, cars, buildings, and electronic equipment.

[0003] For example, the prior art patent publication number CN215720079U discloses an easy-to-install rust-proof screw. When the screw needs to be fixed, the round clamp block is pressed inward to make the round clamp block slide on the outer surface of the rod. The sliding of the round clamp block will cause the reset spring to deform. At this time, the hexagonal block is slid into the hexagonal groove. When the clamping hole and the round clamp block are at the same horizontal position, under the action of the reset spring, the round clamp block will move outward and be clamped into the clamping hole to complete the fixation. At this time, the screw body can be fixed on the object by turning the easy-to-tighten cap. The entire device makes the fixing operation between the screw body and the object simple through the interaction of various components, and no other tools are needed, thereby improving the practicality of the device.

[0004] However, in the above manner, after use, it is inconvenient to disassemble the easy-twist cap, resulting in poor practicality. Utility Model Content

[0011] Wherein, the protective component includes a tough ring and a sealing member, the nut is provided with a mounting groove, the tough ring is placed in the mounting groove, and the sealing member is clamped in the mounting groove through the tough ring.

[0012] The utility model provides a cap screw, by providing the installation and disassembly mechanism. When the stud needs to be driven to rotate by the easy-to-twist cover during specific use, the round rod is firstly screwed, and the round rod drives the two cams to rotate. The two cams abut the two force-bearing members, so that the two force-bearing members move toward each other in the corresponding slide grooves respectively. The two force-bearing members drive the corresponding springs to contract, and drive the two positioning rods to move relative to each other through the two connecting members. After moving to the specified position, the fitting groove is sleeved on the nut, and after being pushed to the specified position, the round rod is loosened. When the spring is reset and stretched, the two force-bearing members can be driven to move toward each other, and the two force-bearing members can indirectly drive the two positioning rods to be inserted into the corresponding positioning grooves to install the easy-tighten cover.
