in the figure: 1. the clamping device comprises a bottom plate, 2, a transverse plate, 3, a vertical plate, 4, a right clamping head seat, 5, a right clamping head piece, 6, a left clamping head seat, 7, a left clamping head piece, 8, a nut, 9, a T-shaped screw, 10, a pressure head, 11, a transverse rod, 12 and a connecting part.

Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

The utility model discloses an anchor clamps that is used for test panel to detain scaffold mechanical properties as shown in figure 1, this anchor clamps include the lower anchor clamps that are connected with the last anchor clamps of testing machine upper portion and are connected with the test machine workstation, go up anchor clamps and include horizontal pole 11, and horizontal pole top middle part is provided with clamping part 12, and the connected mode is welding or screwed connection, pressure head 10 of each sliding connection in the left and right sides of clamping part on the horizontal pole, every pressure head all be provided with horizontal pole sliding fit's through-hole, the through-hole passes through the screw and is connected with the horizontal pole is detachable.

The lower clamp is connected with a test machine workbench through a connecting hole in a bottom plate 1, two first T-shaped grooves in the horizontal direction are arranged on the upper plane of the bottom plate in parallel, the first T-shaped grooves are connected with a left clamp head seat 6 through T-shaped screws 9 and nuts 8, and the left clamp head seat is connected with a left clamp head piece 7 through screws and nuts and used for fixing a vertical rod part of a buckle scaffold of a fixed disc. First T type groove passes through screw 9 and nut 8 and right support sliding connection, and this right support includes diaphragm 2 and riser 3 that mutually perpendicular connects, for reinforcing stability, is provided with the strengthening rib between diaphragm and riser.
