Description

Acid and alkali resistant door lock device Technical Field The utility model relates to the field of door lock devices, in particular to an acid and alkali resistant door lock device. Background In chemical production, equipment is often in corrosive environments such as strong acid and alkali, and ordinary door lock is very easily corroded and damaged, leads to equipment unable normal switch and safety protection, and the magnetism of door plant installation in the past is inhaled and is bumped all to need metal screw to fix, is corroded and damaged in acid and alkali environment, lacks the lock product that can satisfy this kind of special environmental requirement on the present market. Disclosure of utility model The acid and alkali resistant door lock device solves the technical problems that in the prior art, a common door lock is easy to be corroded and damaged, equipment cannot be normally opened and closed and is safe to protect, and in the past, magnetic attraction and door bump of door plate installation are all fixed by metal screws and are corroded and damaged in an acid and alkali environment. The technical scheme adopted by the embodiment of the application is as follows: The acid and alkali resistant door lock device comprises a lock rod, a deflector rod device, a packaging box and a handle, wherein the lock rod is of a telescopic structure and is made of acid and alkali resistant engineering plastics, the deflector rod device is arranged in the packaging box and is connected with the lock rod through a mechanical linkage mechanism to control the telescopic action of the lock rod, the packaging box is an integrally formed corrosion resistant shell and covers the lock rod and a transmission part of the deflector rod device, the handle is connected with the deflector rod device through a rotating shaft, and anti-skid grains are formed on the surface of the handle. The further technical scheme is that the lock rod, the deflector rod device, the packaging box and the handle are made of polypropylene (PP) or polyvinyl chloride (PVC). The further technical scheme is that the tail end of the lock rod is provided with a conical guide part, and a rubber buffer cushion is correspondingly arranged in the clamping groove. The handle adopts a hollow injection molding structure. One or more technical solutions provided in the embodiments of the present application at least have the following technical effects or advantages: 1. Because the arrangement of the lock rod, the deflector rod device, the packaging box and the handle is adopted, the device ensures that the door lock maintains the open and close life for more than 5000 times in the corrosion environment with the pH value of 1-14 through the PP/PVC material combination and the fully-closed structure design, and compared with the maintenance period of a metal lock, the maintenance period of the door lock is prolonged by 5-8 times. The modularized design of the lock rod can quickly replace different length specifications, and the adaptation rate reaches more than 95%. The curvature design of the handle reduces the operating force and saves 40 percent of energy compared with the traditional structure. Through simulation test, the abrasion loss of key transmission parts is less than 0.1 mm/year in the 50 ℃ acid steam environment, and the overall cost of the stainless steel door lock is obviously reduced compared with that of the stainless steel door lock, so that the acid and alkali resistant door lock solves the problem that the door lock is easy to corrode and damage in the strong acid and alkali environment of chemical equipment, improves the safety and reliability of the equipment, reduces the maintenance and replacement cost, and the lock rod can be flexibly processed and manufactured according to different heights of the door so as to meet different design requirements of the door panel, thereby having wide application prospect.
