The utility model discloses a tension control device for a cable drum pay-off rack, and relates to the technical field of cable pay-off devices. The first belt pulley is mounted on an input shaft of the reduction gearbox; the mounting frame is arranged on the reduction gearbox; the air cooling cover is arranged on the mounting frame; the clutch is arranged on the mounting frame, and the clutch is located in the air cooling cover; the second belt pulley is installed at the output end of the clutch, a belt is installed between the second belt pulley and the first belt pulley, and the second belt pulley is located in the air cooling cover. According to the utility model, the technical problem of unstable tension of the cable unwinding device in the prior art is solved.

The utility model belongs to the technical field of material testing equipment, and particularly relates to an overload protection device for a testing machine and compression testing equipment, and the overload protection device comprises a shell, a first connecting module, a second connecting module, an elastic force storage part and an overload feedback module, the second connecting module is arranged at the bottom of the shell in a sliding manner; the elastic force storage piece is arranged in the shell and arranged between the first connecting module and the second connecting module in an abutting mode. The overload feedback module is arranged on the outer side of the bottom of the shell, and the second connecting module is in transmission connection with the overload feedback module through a transmission piece; the overload protection device has an overload protection function, and when a test force value exceeds a safety force value, the second connecting module slides upwards and enables the overload feedback module to trigger a limiting system or an emergency shutdown device, so that the test is interrupted in time, and the test machine or a tested material is prevented from being damaged due to overload.

The utility model discloses an electric meter box with an overload protection function, which relates to the technical field of electric meter boxes and comprises a protective shell, mounting seats are fixedly mounted on two sides of the protective shell, a protective cover plate is attached to the front side of the protective shell in a sliding manner, and closed positioning mechanisms are mounted at the bottom of the protective cover plate and the bottom of the protective shell. According to the electric meter box with the overload protection function, the protection cover plate can slide in the limiting sliding grooves through the sliding blocks to achieve sliding opening and closing of the front side of the protection shell, the phenomenon that the protection cover plate cannot be rotationally opened when the protection cover plate is blocked in a narrow space can be avoided, and convenience of internal maintenance is improved; and the closing positioning mechanism can realize positioning after the protection cover plate is closed through clamping, the use effect of the electric meter box with the overload protection function is improved, active short circuit can be realized through arrangement of an overload protection switch when current is overloaded, and potential safety hazards caused by overload are avoided.

The utility model discloses a clutch mechanism for a hydraulic pump. The clutch mechanism comprises an outer coupling, an inner coupling, a separating mechanism, a tripping mechanism and an electric switch, end face teeth are arranged at the other end of the outer coupling; an inner hole for mounting a ball bearing is formed in the outer coupling, and the outer coupling is arranged on the inner shaft through a small limiting shaft; the ball bearing is in interference connection with the limiting screw, and a locking nut is arranged on the side close to the pump cavity. The limiting small shaft is arranged in an inner hole of the inner coupling, and the limiting right end is connected with the limiting sleeve through external threads; the limiting sleeve is arranged in a screw sleeve on the inner shaft; the left end of the limiting screw is attached to the outer coupler step. The reliability of the overload protection function of the hydraulic pump is effectively improved, the use working condition of a hydraulic system is improved, and therefore the reliability, the safety and the service life of the hydraulic system, accessories of the hydraulic system and even the whole equipment are improved.
