[0006] To achieve the above objectives, the present invention provides the following technical solution: a prestressed anchor with a detachable anchor head, comprising an anchor plate, a base plate fixedly connected to one side of the anchor plate, a reinforcing mechanism fixedly installed on the outer side of the base plate near the anchor plate, an anchor head sleeved on the outer side of the base plate, and a fastening disc sleeved on the outer side of the anchor head.

[0007] The reinforcement mechanism includes a fixed plate, and a locking plate is rotatably connected to the groove in the circumferential direction of the fixed plate via a rotating shaft. Each locking plate has an installation cavity at its other end, and a movable plate is slidably connected to the inner wall of each installation cavity. A return spring is embedded on the left and right sides of the upper end of the movable plate, and the other side of the return spring is connected to the top side of the installation cavity. A pull rod is fixedly connected to the middle of the upper end of the movable plate, and the pull rod passes through the top side of the locking plate. Limiting posts are fixedly connected to the left and right ends of the bottom side of the movable plate, and the limiting posts pass through the bottom side of the locking plate.

[0008] In the above technical solution, the locking plates around the perimeter can be rotated to lock them onto the annular sleeve, further improving the stability of the fastening disc. In addition, the return spring causes the limiting post to engage in the insertion hole, thereby reducing the impact of misrotation of the locking plates.

[0009] As a further preferred embodiment of this technical solution, the outer surface of the front circumference of the anchor head is provided with L-shaped grooves, and the outer side of the anchor head is provided with perforations, each of which is equipped with a retaining sleeve.

[0010] As a further preferred embodiment of this technical solution, the clamping sleeve includes three clamping pieces, which form a locking and fastening structure through the anchor head.

[0011] In the above technical solution, a fastening disc is fitted on the outside of the anchor head, which can further compress and fix the clamp, ensuring the stability of the installation and improving the overall strength.

[0012] As a further preferred embodiment of this technical solution, an annular sleeve is fixedly connected to the outer side of the rear end of the fastening disc, and the annular sleeve has insertion holes arranged in the circumferential direction on the front side of the annular sleeve, with two insertion holes forming a group.

[0013] As a further preferred embodiment of this technical solution, the inner wall of the fastening disc in the circumferential direction is provided with sliders, the outer wall of the sliders is slidably connected to the inner wall of the L-shaped slot, and is engaged in the L-shaped slot by rotation.

[0014] In the above technical solution, the fastening disc slides in the L-shaped slot via a slider, and the slider is locked inside the L-shaped slot by rotation, which improves the stability of the fastening disc and prevents it from falling off.

[0015] As a further preferred embodiment of this technical solution, the slider is inserted into the L-shaped slot so that the insertion hole is aligned with the rotating limiting post.

[0016] As a further preferred embodiment of this technical solution, the limiting post is engaged into the insertion hole by a reset spring.

[0017] In the above technical solution, the return spring is pulled to disengage the limiting post from the insertion hole, and the fastening plate is rotated to remove it from the anchor head, which facilitates the subsequent disassembly of the anchor head.

[0018] This utility model provides a prestressed anchor with a detachable anchor head, which has the following advantages:

[0019] (1) By fitting a fastening disc on the outside of the anchor head, the present invention can further compress and fix the clamping cylinder, ensuring the stability of the installation and improving the overall strength. The fastening disc slides in the L-shaped groove through a slider, and the slider is locked in the inside of the L-shaped groove by rotation, which improves the stability of the fastening disc and avoids the phenomenon of falling off.

[0020] (2) By installing a reinforcement mechanism, this utility model can make the locking plate around the ring sleeve to be locked, thereby further improving the stability of the fastening plate. In addition, under the action of the return spring, the limiting post is locked into the insertion hole, thereby reducing the impact of the locking plate being rotated by mistake. Furthermore, the return spring can be pulled to pull the limiting post out of the insertion hole, and the fastening plate can be rotated to remove it from the anchor head, which facilitates the subsequent disassembly of the anchor head.
