Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Referring to fig. 1 to 6, embodiment 1: the anchor bolt suitable for the integrated plate comprises a screw rod 1 and an expansion sleeve 2 which are in threaded connection, clamping jaws which are circumferentially distributed are arranged at the bottom of the expansion sleeve 2, and the screw rod 1 comprises a nut mounting part 11, a polished rod part 12 and an expansion sleeve mounting part 13 which are sequentially arranged along the axial direction; the nut mounting part 11 and the expansion sleeve mounting part 13 are both provided with thread structures; the nut mounting part 11 is used for connecting a lock nut in a threaded manner; the polished rod part 12 is used for limiting the displacement of the screw along the spiral of the expansion sleeve 2; the top of the expansion sleeve 2 is provided with a limiting structure 21 for preventing the expansion sleeve 2 from rotating, and the limiting structure 21 is a boss or a groove; the top of the screw rod 1 is provided with a slot for inserting a driving piece which drives the screw rod to rotate.
The axial length of the expansion sleeve is more than or equal to 6 mm. And then fix the bottom of expansion sleeve on the bottom plate, the top is located the rock wool board.
The outer diameter of the polished rod part is larger than the minimum outer diameter of the expansion sleeve mounting part. And further realize the screw rod and the relative screw process of expansion sleeve to the spacing of polished rod portion. Preferably, the outer diameter of the polished rod portion is larger than the smallest outer diameter of the expansion sleeve mounting portion. And when the machining is convenient, the thread structures are machined at the two ends of the optical axis, so that the structure of the optical axis part in the middle of the threads at the two ends can be realized. The processing is simple.
The slots are prismatic slots. Preferably, the slot is a hexagonal prism slot. The driver may be a power hex wrench.
The mounting structure also comprises a mounting sleeve 5, wherein an inner hole of the mounting sleeve 5 is a through hole for longitudinally sliding and connecting a screw rod; the bottom of the mounting sleeve is provided with a clamping structure 51 matched with the limiting structure; a gripping member is fixed to the outer wall of the mounting sleeve 5. The limiting sleeve is convenient to limit the expansion sleeve in the mounting hole penetrating through the integrated plate. The clamping structure comprises at least two protrusions. Preferably, the clamping structure is two oppositely arranged protrusions; the limiting structure is a groove matched with the protrusion. A handle extending outwards in the radial direction is fixed on the outer wall of the mounting sleeve and is used as a gripping part.
The bottom of the expansion sleeve 2 is provided with strip-shaped gaps which are circumferentially distributed and separate adjacent clamping jaws; the bottom of the claw is provided with a protrusion extending outwards. When the screw rod does not extend into the clamping jaw, the expansion sleeve is provided with a clamping jaw which retracts inwards; when the screw rod stretched into jack catch department, expansion sleeve was equipped with jack catch department and expands outward, and expansion sleeve is equipped with the external diameter that the external diameter of jack catch department is greater than the external diameter at expansion sleeve top. The expansion sleeve is provided with a strip-shaped gap and is provided with a thread structure at the position where the strip-shaped gap is not arranged. The looseness prevention performance is improved. The expansion sleeve is provided with the jaws and contracts inwards, namely, in the manufacturing process of the expansion sleeve, after the strip-shaped gaps are formed, the jaws are bent inwards, and then the jaws contract inwards. At this time, the orthographic projection area of the jaws is located within the orthographic projection area of the top of the expansion sleeve. When the clamping jaws are not retracted inwards, namely when the bolt extends into the clamping jaws, the outer diameter of the protrusions at the bottoms of the clamping jaws is larger than that of the tops of the expansion sleeves.
