Abstract
The utility model provides an interlocking device's of examination article chamber door protective structure, examination article case and bag contain box and chamber door, examination article incasement is equipped with experimental port, the box inner wall is equipped with the chain socket of door, position that the chamber door back corresponds chain socket is equipped with a chain bolt, protective structure contain: the protection casing, it is located examination article incasement and detains door outside the chain socket, the protection casing has unlimited portion to the position of the chain socket head of answering the door, makes the chain socket head of door exposed. Through setting up the protection casing outside the chain socket of door at examination article incasement wall, play spacing when closing and avoid probably facing each other the damage of chain socket when high -current test.
Description
Technical field
This utility model relates to a kind of particular power source technical field of measurement and test, is specifically related to the interlock of a kind of test product chamber door
Safeguard structure.
Background technology
General high voltage, big electric current particular power source test equipment in, for security protection, the company of being provided with at test product case
Locking device, effect is to open test product chamber door user of service, when test product being operated or correlation meter is installed, energy
Enough guarantee tests port ground connection or not charged.Normal practice is that installation door is chain, by the change in location of chamber door, is switched on or switched off
Security protection circuit.But in actual use, following two point defects can be there are:
The most tested product it may happen that blast, damage door interlock, cause follow-up test to enter in process of the test
OK；
2. to only rely on interlock body spacing for chamber door, and life-time service is likely to result in interlock displacement or comes off.
Utility model content
The purpose of this utility model is to provide the safeguard structure of the interlock of a kind of test product chamber door, by test product case
Outside the chain socket of door of inwall, protective cover is set, plays door when closed spacing and avoid may be right when cranking test
The damage of the chain socket of door.
In order to achieve the above object, this utility model is achieved through the following technical solutions:
The safeguard structure of the interlock of a kind of test product chamber door, described test product case comprises casing and chamber door, test product case
Inside being provided with test port, cabinet wall is provided with the chain socket of door, and it is chain slotting that the position of the corresponding chain socket in the chamber door back side is provided with door
Pin, is characterized in that, described safeguard structure comprises:
Protective cover, it is positioned at test product case and is buckled in outside the chain socket of described door, and protective cover is to chain socket head of answering the door
The position in portion has opened portion, makes the chain socket head of door exposed.
The safeguard structure of the interlock of above-mentioned test product chamber door, wherein:
Described protective cover has the Baltimore groove of a shape and described door chain socket form fit.
The safeguard structure of the interlock of above-mentioned test product chamber door, wherein, also comprises:
Connector, described protective cover is fixed on the inwall of described casing by connector.
The safeguard structure of the interlock of above-mentioned test product chamber door, wherein:
On described protective cover, the outside of opened portion socket head chain with door flushes.
This utility model compared with prior art has the advantage that by the door chain socket peripheral hardware at test product chamber interior wall
Put protective cover, play door when closed spacing and avoid when cranking test may the damage of the chain socket of opposite house.
Accompanying drawing explanation
Fig. 1 is use state reference map one of the present utility model；
Fig. 2 is use state reference map two of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, this utility model is done and explains further
State.
As shown in Figure 1, 2, the safeguard structure of the interlock of a kind of test product chamber door, described test product case comprise casing 4 with
And chamber door 7, it being provided with test port 5 in test product case, casing 4 inwall is provided with the chain socket of door 2, the corresponding chain socket 2 in chamber door 7 back side
Position be provided with the chain latch of door 6, it is characterised in that described safeguard structure comprises: protective cover 1, and it is positioned at test product case also
Being buckled in outside the chain socket of described door 2, protective cover 1 has opened portion to the position of chain socket 2 head of answering the door, and makes door chain slotting
Seat 2 heads are exposed, and concrete, protective cover 1 can be fixed on the inwall of described casing 4 by connector.
Described protective cover 1 has the Baltimore groove of a shape and described door chain socket 2 form fit.
On described protective cover 1, the outside of opened portion socket chain with door 2 head flushes.
Described connector can be screw 3 or elastic displacement structure, and elastic displacement structure can be generally that spring etc. has
The mechanism of displacement function, so can conveniently adjust the position of protective cover 1, so that chamber door 7 is played position-limiting action, reliable at latch
When ground inserts socket, outside protective cover 1, withstand chamber door 7, it is to avoid directly active force is on socket, after avoiding life-time service, door
The displacement of chain socket 2 even comes off and cannot normally work.
The operation principle of this safeguard structure is, when closing 7 test product chamber door, door chain latch 6 insert in chain socket 2,
Providing the feedback signal of Guan Bi, test is normally carried out, when opening test product chamber door 7, chain latch 6 in the chain plug housing of door 2
Extracting, provide the feedback signal of disconnection, control system carries out ground connection, it is ensured that the test port 5 in casing 4 is not charged, works as generation
During the acutely situation such as blast, fragment can damage protective cover 1, and the chain socket of door 6 in protective cover 1 is by unaffected.
Although content of the present utility model has been made to be discussed in detail by above preferred embodiment, but it should be appreciated that
The description stated is not considered as restriction of the present utility model.After those skilled in the art have read foregoing, for
Multiple amendment of the present utility model and replacement all will be apparent from.Therefore, protection domain of the present utility model should be by appended
Claim limit.
