Detailed Description

The embodiments of the invention will be described in detail below with reference to fig. 1 to 3, but the invention can be implemented in many different ways as defined and covered by the claims.

With reference to fig. 1 to 3, the balance weight moving bracket for a pumping unit provided by the present invention comprises an L-shaped positioning plate 1 fixedly connected to a crank 11 through a bolt 8, wherein a threaded hole 10 is transversely formed in an upper portion of the L-shaped positioning plate 1, and an adjusting screw 7 is disposed through the threaded hole 10; a fixing plate 3 is welded at the lower part of the L-shaped positioning plate 1, a shaft 9 is transversely arranged on the side surface of the fixing plate 3, and a swinging arm 4 is movably sleeved on the shaft 9; the upper part of the swing arm 4 is movably connected with an upper movable plate 2, the lower part of the swing arm 4 is movably connected with a lower movable plate 5, and the lower movable plate 5 is longitudinally provided with a through hole 6; the adjusting screw 7 can act on the upper movable plate 2.

According to the structure of above-mentioned embodiment can discover, this utility model is an utilize the through-hole 6 of seting up on the activity board 5 down as the crow bar fulcrum, reach and avoid the crow bar to skid, thereby the purpose of safe prying balancing piece 12, activity board 5 passes through swing arm 4 swing joint upper movable plate 2 down, and swing arm 4 movable sleeve establishes on the axle 9 of the side of fixed position fixed plate 3, consequently, act on movable plate 2 when adjusting lead screw 7, swing arm 4 will rotate around axle 9, thereby make activity board 5 lateral shifting down, this embodiment makes the staff at the in-process of prying balancing piece 12, can adjust the position of activity board 5 down at any time, make the crow bar always can obtain the fulcrum of ideal position.
