Abstract
The utility model discloses an anticorrosive pneumatic door lock, which belongs to the technical field of electrical equipment, and is arranged at a cabinet bolt mounting hole, and comprises a fixed bottom plate, an inflatable shell and a bolt component, wherein the fixed bottom plate is used for being fixed at the cabinet bolt mounting hole, and the inflatable shell and the bolt component are arranged above the fixed bottom plate; meanwhile, other parts of the bolt are protected by the inflatable shell, the air blowing joint which is connected with the air source is arranged at the air blowing joint mounting hole, the air source blows air into the inflatable shell, the air in the inflatable shell is kept to be in positive pressure, and corrosive gas is prevented from entering the shell.
Description
Technical Field
The utility model relates to an electrical equipment technical field, concretely relates to pneumatic lock of anticorrosive type.
Background
The original bolt is used for doors and windows, is a part for preventing the doors and windows from being opened, has a simple structure, is convenient and practical, and is widely used in various fields including the field of electric control cabinets. But the bolt in the present electrical control cabinet because each part of bolt exposes in the acid-base environment for a long time in the actual use, the condition that the corrosion bonds together often takes place easily between each part of bolt, influences the normal of switch board cabinet door and opens and shuts, has very big limitation.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a pneumatic lock with anticorrosive effect to the shortcoming of pneumatic bolt among the prior art.
The technical scheme of the utility model is that: the utility model provides an anticorrosive type pneumatic door lock, set up in rack bolt mounting hole department, including being used for fixing the PMKD in rack bolt mounting hole department, install the casing of aerifing in the PMKD top, the bolt subassembly includes from the last air source interface that down connects gradually, the stainless steel cylinder, the stainless steel bolt, PMKD with aerify on the casing be equipped with respectively with rack bolt mounting hole setting on same straight line the bolt through-hole, the cylinder mounting hole, the bottom cover of stainless steel bolt is equipped with anticorrosive type outer tube, the length of anticorrosive type outer tube and the stroke phase-match of stainless steel cylinder, the internal diameter of bolt through-hole and the external diameter phase-match of anticorrosive type outer tube.
According to the further technical scheme, a first cavity is formed between the air inflation shell and the fixed bottom plate, and an air blowing joint mounting hole communicated with the first cavity is formed in the air inflation shell.
In a further technical scheme, the anti-corrosion outer sleeve is a PFA outer sleeve.
The utility model has the advantages that:
the utility model provides an anti-corrosion pneumatic door lock, which is characterized in that an anti-corrosion outer sleeve is sleeved on the stroke part of a bolt contacted with a cabinet, so as to prevent the bolt from being bonded with other parts on the cabinet; meanwhile, other parts of the bolt are protected by the inflatable shell, the air blowing joint which is connected with the air source is arranged at the air blowing joint mounting hole, the air source blows air into the inflatable shell, the air in the inflatable shell is kept to be in positive pressure, and corrosive gas is prevented from entering the shell.
Drawings
FIG. 1 is a schematic structural view of the present invention,
figure 2 is an exploded view of the structure of the utility model,
the device comprises a fixing base plate 1, a fixing base plate 11, a bolt through hole 2, an inflatable shell 21, a cylinder mounting hole 22, a blowing connector mounting hole 3, an air source interface 4, a stainless steel cylinder 5, a stainless steel bolt 51 and an anti-corrosion outer sleeve.
Detailed Description
The invention will be further elucidated below by means of non-limiting examples, with the understanding that the invention is not limited thereto.
As shown in fig. 1-2, the utility model relates to an anticorrosive type pneumatic lock sets up in rack bolt mounting hole department, including being used for fixing at the PMKD 1 of rack bolt mounting hole department, installing aerifing casing 2, the bolt subassembly in PMKD 1 top, the bolt subassembly includes from last air supply interface 3, stainless steel cylinder 4, the stainless steel bolt 5 that down connects gradually.
The fixing bottom plate 1 and the inflatable shell 2 are respectively provided with a bolt through hole 11 and a cylinder mounting hole 21 which are arranged on the same straight line with the cabinet bolt mounting hole, and the stainless steel bolt 5 below the stainless steel cylinder 4 is driven to move up and down along the cabinet bolt mounting hole, so that the cabinet door of the cabinet can be locked and opened.
The bottom cover of stainless steel bolt 5 is equipped with anticorrosive type outer tube 51, and is specific, in this embodiment, anticorrosive type outer tube 51 adopts the PFA outer tube. The length of the anti-corrosion outer sleeve 51 is matched with the stroke of the stainless steel cylinder 4, and the inner diameter of the bolt through hole 11 is matched with the outer diameter of the anti-corrosion outer sleeve 51.
A first cavity is formed between the inflatable shell 2 and the fixed base plate 1, an air blowing joint mounting hole 22 communicated with the first cavity is formed in the inflatable shell 2, and the air blowing joint mounting hole 22 is used for mounting an air blowing joint connected with an air source.
The utility model prevents the bolt from being bonded with other parts on the cabinet by sleeving the anti-corrosion outer sleeve 51 on the stroke part of the bolt contacted with the cabinet; meanwhile, other parts of the bolt are protected by the inflatable shell 2, the air blowing joint at the air blowing joint mounting hole 22 is connected with an external air source, the external air source blows air into the inflatable shell 2, the air in the inflatable shell 2 is kept to be in positive pressure, and corrosive gas is prevented from entering the shell.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
