Clamp for reinforcing the end of ventilation duct

Abstract

The invention relates to a fixture for reinforcement of the end part of a ventilating duct. The fixture comprises a support device and a pressing device, wherein the support device comprises a base; first oblique surfaces are arranged at the front side, rear side, left side and right side of the upper end of the base respectively; dovetail slideways are arranged on the first oblique surfaces; stop blocks are arranged at the front end, rear end, left end and right end of the base respectively; second oblique surfaces are arranged on the stop blocks; push blocks are arranged on the first oblique surfaces, and comprise slide rails; inner oblique surfaces parallel to the first oblique surfaces correspondingly are arranged at the lower end faces of the inner sides of the push blocks; outer oblique surfaces parallel to the second oblique surfaces correspondingly are arranged at the lower end faces of the outer sides of the push blocks; first pressure springs are fixedly arranged between the outer oblique surfaces and the corresponding second oblique surfaces; and a plurality of vertically formed strip-type holes are formed in the outer end faces of the push blocks. With the adoption of the internal support and external pressing combined mode, the ventilating duct is pressed, so that a situation that angle iron is not fixed tidily due to the fact that an alloy iron sheet is liable to fold during manual fixing is avoided; the personal security is ensured; and the probability of a situation that personnel is scratched is reduced.

Description

technical field [0001] The invention relates to the technical field of marine ventilation pipe processing equipment, in particular to a clamp for reinforcing the end of a ventilation pipe. Background technique [0002] The interior of the cabin is equipped with ventilation pipes leading to the outside. At present, alloy iron sheets with high corrosion resistance are often used to make ventilation pipes. The alloy iron skin is thin and easy to deform. Formed and riveted with rivets during installation. The alloy iron skin is soft. In order to meet the assembly needs, angle steel is usually riveted at the end of the ventilation duct made of alloy iron skin to strengthen the end of the ventilation duct and facilitate the connection of the ventilation duct. [0003] However, the end of the iron sheet is relatively sharp, and it is very easy for the operator to touch the end of the ventilation pipe when riveting the angle steel to the end of the ventilation pipe, and the probabi...

[0003] However, the end of the iron sheet is relatively sharp, and it is very easy for the operator to touch the end of the ventilation pipe when riveting the angle steel to the end of the ventilation pipe, and the probability of being scratched is relatively high. In order to protect the safety of personnel and improve the processing efficiency of the ventilation pipe, people need a A clamp that can assist manual reinforcement of the end of the ventilation duct with angle steel
