Description

Mechanical expansion shell anchor head Technical Field The utility model relates to the technical field of anchor heads, in particular to a mechanical expansion shell anchor head. Background The existing expansion shell type anchoring head is a device for fixing the hollow anchor rod body in the center of an anchor hole by generating anchoring force through extrusion friction between an expansion shell and the inner wall of the anchor rod hole and applying prestress. The authority publication number CN221462354U describes a mechanical expansion shell anchor head, which comprises an anchor head main body and two guide strips, wherein the inside of the anchor head main body is provided with a through groove, the left side and the right side of the anchor head main body are respectively provided with a chamfer, and the two guide strips are respectively arranged on the corresponding chamfer. The mechanical expansion shell anchor head realizes the anchoring problem of large diameter, improves the overall strength of the anchor body, is easy to ensure the quality, has better positioning of the top of the anchor head main body, is favorable for the initial enlargement of the wedge-shaped expansion shell, and has smooth guiding and stable operation, thereby solving the problem of the blocking of the wedge-shaped expansion shell in the initial operation. The problem that the wedge-shaped expansion shell is blocked in initial operation can be solved, the problem that the anchor head main body is poor in guiding in the initial operation stage is eliminated through the integral design, and the requirement of large-diameter anchoring is met. Disclosure of utility model The utility model provides a mechanical expansion shell anchor head, which is characterized in that a groove of a clamping strip is sleeved on a tooth of an anchor head main body through a sliding groove, a tooth, the clamping strip, a groove and a stop block, so that the clamping strip is clamped and embedded into the anchor head main body, and the stop block at the bottom is utilized to limit the sliding out of an expansion piece, so that the expansion piece is prevented from being pulled out in the use process, and the limiting effect is realized. In order to achieve the purpose, the utility model is realized by the following technical scheme that the mechanical expansion shell anchor head comprises: Anchor head main part and two piece that rise, two the piece that rises is located anchor head main part both sides, two spouts have been seted up at the top of anchor head main part, anchor head main part is located two spouts department and all inwards extends and be equipped with two teeth, two the piece that rises all extends and is equipped with the card strip in one side that is close to each other, the notch has been seted up to outer wall one side of card strip, notch and tooth mutually support, two the outer wall bottom of tooth all extends and is equipped with two dogs. As the mechanical expansion shell anchor head, the outer wall of the clamping strip is embedded in the chute in a sliding way. As the mechanical expansion shell anchor head, an opening is formed in the bottom of the outer wall of the anchor head main body. As the mechanical expansion shell anchor head, the upper surface of the outer wall of the anchor head main body is provided with two water outlets. As the mechanical expansion shell anchor head, the two sides of the outer wall of the anchor head main body are provided with the reinforcing ribs in an extending mode. The utility model provides a mechanical expansion shell anchor head. The beneficial effects are as follows: (1) The mechanical expansion shell anchor head can enable the notch of the clamping strip to be sleeved on the tooth of the anchor head main body through the sliding groove, the tooth, the clamping strip, the notch and the stop block, so that the mechanical expansion shell anchor head is clamped in the anchor head main body, and the stop block at the bottom is utilized to limit the expansion piece from sliding out, so that the expansion shell anchor head cannot be pulled out in the use process, and plays a limiting role.
