[0002] Traditional elevator components are typically installed using expansion anchors, but existing anchors can be difficult to install and remove, have insufficient expansion force, or exhibit complex structures. Common expansion bolts rely on tapping or tightening nuts to expand the expansion sleeve, making them difficult to remove after installation and prone to loosening due to vibration, compromising elevator safety. Furthermore, some anchors require specialized tools for installation, making the process cumbersome and prone to slipping within the concrete hole, resulting in a loosened anchor. Summary of the Invention

Then, the connecting column and the interference sleeve are driven to move by the driving mechanism, so that the interference sleeve is separated from the elastic sheet, and the connecting column drives the interference cone to move, so that the interference cone is in contact with several elastic sheets, so that the elastic sheet expands outward and is in contact with the inner wall of the wall socket, so that the anchor rod can be installed. After installation, the driving mechanism is blocked by the blocking mechanism.

[0005] As a further improvement of the present invention, a plurality of interference rods are fixed on the outer ring wall of the elastic sheet in a matrix manner, and the interference rods are located outside the interference sleeve; Through the above technical solution, the friction between the elastic sheet and the installation position can be increased, thereby improving the stability after installation.

[0006] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

When the cam is in the closed position, the sliding block is in contact with the inner wall of the sliding groove on the contact sleeve, and the contact sleeve is moved to the outside of the contact sleeve. When the cam is in the closed position, the sliding block is in contact with the inner wall of the sliding groove on the contact sleeve, and the contact sleeve is moved to the outside of the contact sleeve. When the cam is in the closed position, the sliding block is in contact with the inner wall of the sliding groove on the contact sleeve, and the contact sleeve is moved to the outside of the contact sleeve.

[0007] As a further improvement of the present invention, a gripping rod is embedded in the rotating rod on a side away from the rotating disk, and the end of the gripping rod is screwed to the rotating rod via a shaft; With the above technical solution, after the rotating rod is rotated out of the rotating disk, the gripping rod is rotated out of the rotating rod, so that the rotating rod can be rotated by gripping the gripping rod, which is convenient to operate.

[0008] As a further improvement of the present invention, the blocking mechanism includes: a blocking plate, the blocking plate is embedded in the circular groove at the end of the anchor rod, an arc-shaped slide rail is fixed on the side wall of the blocking plate, the arc-shaped slide rail is slidably arranged in the arc-shaped slide groove on the inner wall of the circular groove, and a rectangular opening is provided on the blocking plate, and the rectangular opening is arranged corresponding to the rotating rod; a return spring, the return spring is arranged in the arc-shaped slide groove on the blocking plate, and the two ends of the return spring are respectively fixed to the inner wall of one side of the arc-shaped slide groove and the end wall of the arc-shaped slide rail; an arc-shaped strut, the arc-shaped strut is arranged through the return spring, one end of the arc-shaped strut is fixed on the inner wall of the arc-shaped slide groove, and the other end of the arc-shaped strut is movably inserted in the arc-shaped slide rail; Through the above technical solution, when the rotating rod needs to be rotated, the blocking plate is rotated, and the blocking plate drives the arc slide rail to rotate. The arc slide rail resists the return spring, causing the return spring to be compressed. The rectangular opening is located on one side of the rotating rod. At this time, the rotating rod can be rotated out. When the installation is completed, the rotating rod is rotated into the rectangular groove at the end of the anchor rod, and the blocking plate is loosened. The blocking plate rotates under the elastic force of the return spring, so that the blocking plate resists the rotating rod and prevents the rotating rod from rotating outward.

[0009] As a further improvement of the present invention, the arc-shaped support rod is located on both side walls of one end of the arc-shaped slide rail, and the limit sliders are slidably arranged in the slide grooves on both sides of the arc-shaped slide rail; Through the above technical solution, the stability of the arc-shaped support rod during movement can be increased, and the separation of the arc-shaped slide rail and the arc-shaped support rod can be avoided.

[0010] As a further improvement of the present invention, the front and rear sides of the inner ring wall of the gasket are fixed with connecting support plates, which are movably inserted into the strip groove on the anchor rod, and the upper and lower side walls of the connecting support plate are fixed with sliding inserts, which are slidably arranged in the slide groove on the inner wall of the strip groove; Through the above technical solution, the gasket can be supported by connecting the support plate so that the center point of the gasket and the center point of the anchor rod are on the same plane, thereby increasing the movement of the gasket while ensuring that the nut contacts the middle side of the gasket.

[0011] As a further improvement of the present invention, a covering cap is screwed onto one end of the anchor rod adjacent to the nut through a thread, and a limiting rod is movably inserted into the upper and lower ends of the covering cap. One end of the limiting rod is inserted into the end wall of the anchor rod, and the other end of the limiting rod is fixed to the upper and lower sides of the pull rod after passing through the covering cap. The pull rod is located in a slot on the side wall of the covering cap. A limiting spring is sleeved on the limiting rod, and the two ends of the limiting spring are respectively fixed to the limiting rod and the inner wall of the covering cap. Through the above technical solution, after the anchor rod is inserted into the wall, the covering cap is screwed onto the anchor rod, and under the elastic force of the limiting spring, the limiting rod is driven to be inserted into the anchor rod, which can avoid the covering cap from rotating. The covering cap can be knocked to make the anchor rod inserted into the appropriate position inside the wall. When the driving mechanism and the blocking mechanism need to be operated, the pull rod is pulled outward, and the pull rod drives the limiting rod to move outward and separate from the anchor rod, thereby not affecting the use of the anchor rod itself.

[0012] As a further improvement of the present invention, a grip groove is provided on the side wall of the covering cap, and the middle end of the pull rod is located in the grip groove; With the above technical solution, it is convenient to hold the pull rod by hand, thereby facilitating the movement of the pull rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. One-touch expansion and contraction is achieved through the drive mechanism. During installation, only the drive screw needs to be rotated to complete the expansion and fixation of the elastic sheet. During disassembly, the reverse operation can quickly release the anchoring. 2. The dual limit design of the contact sleeve and elastic sheet effectively prevents loosening caused by vibration. The matrix contact rod further enhances the pull-out resistance, allowing the anchor bolt to remain stable under dynamic loads, meeting the high safety requirements of elevator components. 3. The driving mechanism integrates a rotating rod, a grip rod and a blocking mechanism. The operation can be performed by pulling the rotating rod outward. The blocking plate is automatically locked by the return spring to avoid accidental contact. 4. The blocking mechanism adopts double guidance of arc slide rail and limit slider to prevent parts from falling off; the covering cap has both dust-proof and auxiliary knocking functions to protect the internal driving components.
