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.

The utility model relates to a dustproof and waterproof vertical charging pile which comprises a mounting plate, a charging pile body is mounted on the outer side of the mounting plate, the charging pile body is composed of a rear cover and a front cover, a display screen and a light bar are arranged on the surface of the front cover, and two side blocks are mounted on the outer surface of the mounting plate and located on the upper side of the charging pile body. A rain shielding cover is rotatably mounted between the two side blocks through a rotating shaft, a raindrop sensor is arranged on the upper surface of the rain shielding cover, and a turnover mechanism capable of driving the rain shielding cover to turn over when the raindrop sensor detects raining is arranged on the outer side of the mounting plate; the outer side of the rear cover is provided with a charging head slot, and the bottom of the rear cover is provided with a charging wire. When the raindrop sensor detects raining, the turnover mechanism drives the rain cover to turn over and cover the outer side of the charging pile body to shield rain and protect the charging pile body, so that the situation that rainwater enters the charging pile body to cause short circuit or other electrical problems is avoided, the cost is low, and the waterproof effect is good.

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.

The utility model discloses a positioning structure for a distribution box body welding clamp frame, which comprises a fixed bottom plate, a rail rod is fixedly arranged on the surface of the fixed bottom plate through a bolt, the surface of the rail rod is connected with the clamp frame in a sliding manner, a metal block is arranged on the surface of the clamp frame, a plurality of limiting holes are formed in the surface of the fixed bottom plate, and the metal block is arranged in the limiting holes. And the inner wall of the metal block is in threaded connection with a bolt rod. The round plate and the spring are used in cooperation, the sliding rod can drive the hemisphere block to vertically move on the top of the fixed bottom plate, the outer wall of the hemisphere block and the inner wall of the clamping groove are both spherical surfaces, and then the hemisphere block can slide out of the clamping groove, so that movement of the welding clamp frame on the surface of the sliding rail can be pre-positioned, and the welding clamp frame is convenient to use. When the clamp frame needs to be locked, it can be guaranteed that the bolt rod and the limiting hole of the fixed bottom plate are conveniently aligned, and then the purpose of improving the locking and aligning convenience when the position of the welding clamp frame is adjusted is achieved.
