The utility model provides a kind of for angle stroke valve non-contact installation mechanism, at least two clamping holes are opened in the gripping handle of valve upper portion, positioning hole is opened in the flange plate of valve upper portion, and it is matched with clamping hole, installation mechanism includes the clamping rod matched with clamping hole, the number of clamping rod is equal to the number of clamping hole, the upper portion of clamping rod is provided with connecting plate, the outside of connecting plate is provided with force applying element, the utility model can be clamped into the clamping hole and positioning hole matched with it by clamping rod, then it is tightened operation by the aid of force applying element, it can be realized not to contact angle stroke valve to realize the firm efficient installation or dismounting operation to it, greatly improve the efficiency of installation and dismounting, operation is more convenient and efficient.

The utility model discloses a LED display screen with remote switch receiver, it includes LED display screen, the front side fixedly connected with rectangular box of LED display screen, the front side fixedly connected with two fixed blocks of LED display screen, the surface of fixed block is equipped with the inclined plane, the inner wall of two fixed blocks is connected with two symmetries connecting rod of mutual sliding, the surface sliding of connecting rod is connected with two symmetries ring block, four ring blocks are fixedly connected with receiver between mutual, both ends of two connecting rods are fixedly connected with L type pole. The utility model discloses through holding and connecting the L type pole of fixed L type pole and exerting the pulling force of connecting rod, make connecting rod along the inner wall of fixed block and slide, thereby make connecting rod drive receiver and fixed block separate, can reach the convenient nature of effective improvement of LED display screen and receiver between dismounting, and the purpose that fixed effect is better.

This utility model discloses a vibrating frame for a benchtop soil aggregate structure analyzer, comprising an analyzer, a vibration assembly mounted on the surface of the analyzer, four bases fixedly connected to the inner wall of the analyzer, a water bucket on the top of each of the four bases, and two sliding plates fixedly connected to the top of each of the four bases by bolts. Sliding blocks are slidably connected to the surfaces of the two sliding plates. Two arc-shaped plates are mounted on the top of each base; the bottom of the left arc-shaped plate is fixedly connected to the top of the base, and the surface of the right arc-shaped plate is fixedly connected to the two sliding blocks. This utility model utilizes a rotating threaded rod, causing the threaded rod to drive an internal threaded block to press against the arc-shaped plates, thereby fixing the water buckets in place. This effectively reduces the displacement of the water buckets during vibration, thus minimizing collisions between the vibrating frame and the water buckets.
