Description
Technical Field
The utility model discloses be applied to the technical field of closing the door mechanism.
Background
Today, the electronic testing industry is rapidly developing, the functional requirements for electronic products are increasing, and in order to provide an absolute testing environment, various shielding boxes are needed to isolate the interference of the external environment. However, get the in-process of putting the test product at manual work or machine and need carry out opening of shielding case, in order to guarantee the sealed of shielding case, need set up seal structure at the edge of shield door usually, the setting up of seal structure makes the required strength of closing of shield door great, and the door of the shielding case on the market is mostly manual operation, and manual operation's the degree of difficulty is great, and the cost time is long, is difficult to guarantee the lock degree of a body and box. The structure can avoid these problems well.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome prior art not enough, provide a convenient to use is swift, safe and reliable, sealed effectual and use manpower sparingly close a mechanism.
The utility model adopts the technical proposal that: the utility model discloses a mounting bracket, shield door, locking cylinder and wedge, the shield door articulates on the mounting bracket, wedge sliding fit is in on the mounting bracket, the one end of locking cylinder with the mounting bracket is connected, the expansion end of locking cylinder with the wedge is connected, be provided with the spigot surface on the wedge, be provided with on the shield door with the spacing subassembly of spigot surface complex.
According to the scheme, the wedge block is driven by the locking cylinder to slide on the mounting frame, so that the wedge block advances, contacts with the limiting assembly and drives the shielding door to be buckled and sealed with the box body, and the wedge block is driven to return to be unlocked. Through locking cylinder realizes mechanical locking as power component, provides sufficient power and locks, need not the manual locking that shields the door that carries on, and is convenient and use manpower sparingly fast. And meanwhile, the cylinder is adopted as a locking structure, so that the locking effect can be ensured. Through the guiding surface is in the direction and spacing are carried out to spacing subassembly, and then drive the shield door is close to and the lock is in on the mounting bracket, realize the sealed of shielded cell.
According to a preferable scheme, the locking cylinder is hinged to the mounting frame, and the movable end of the locking cylinder is hinged to and matched with the wedge block.
According to the scheme, the locking cylinder is arranged in a mode that two ends are hinged, so that the angle of the locking cylinder can be automatically adjusted, the wedge-shaped block is adaptive to the angle change of the stress of the wedge-shaped block, and the locking cylinder is prevented from being damaged due to uneven stress.
According to a preferable scheme, the mounting frame is provided with a linear guide rail, and the wedge block is in sliding fit with the linear guide rail through a sliding block.
According to the scheme, the linear guide rail is arranged to improve the linear movement precision of the wedge-shaped block.
One preferred scheme is that the mounting frame is provided with an in-place sensor matched with the shielding door.
According to the scheme, the shield door is detected whether to be in place through the in-place sensor, so that the shield door is automatically started after being in place, the effect of automatically closing the door is achieved, and meanwhile the locking cylinder is prevented from being started by mistake to cause the door to be closed.
Preferably, the spacing assembly comprises a bearing which is rotatably fitted on the screen door.
According to the scheme, the bearing is used as the limiting part, so that the abrasion of the wedge block is reduced, and the service life is prolonged.
Preferably, an end of the guide surface away from the locking cylinder is rounded.
It can be seen from the above-mentioned scheme that the design through the fillet shape realizes passing through gradually spacing subassembly drives the shield door is closed.
Preferably, a sealing cover is arranged on the mounting frame.
According to the scheme, the action component is protected by arranging the sealing cover.

FIG. 2 is a schematic view of the lock cylinder and the wedge block in a first view;
fig. 3 is a schematic structural view of the locking cylinder and the wedge block from a second perspective.
Detailed Description
As shown in fig. 1 to 3, in this embodiment, the utility model discloses a mounting bracket 1, shield door 2, locking cylinder 3 and wedge 4, shield door 2 articulates on mounting bracket 1, wedge 4 sliding fit is in on the mounting bracket 1, locking cylinder 3's one end with mounting bracket 1 connects, locking cylinder 3's expansion end with wedge 4 connects, be provided with spigot surface 5 on the wedge 4, be provided with on shield door 2 with the spacing subassembly of spigot surface 5 complex.
In this embodiment, the locking cylinder 3 is hinged to the mounting frame 1, and the movable end of the locking cylinder 3 is hinged to the wedge block 4.
In this embodiment, a linear guide rail 6 is arranged on the mounting frame 1, and the wedge block 4 is slidably fitted on the linear guide rail 6 through a slider.
And the mounting rack 1 is provided with an in-place sensor 7 matched with the shielding door 2.
The limiting assembly comprises a bearing 8 which is rotatably matched on the shielding door 2.
The end of the guide surface 5 far away from the locking cylinder 3 is in a round angle shape.
The mounting frame 1 is provided with a sealing cover.
The utility model discloses a theory of operation:
after the operator puts into the shielded cell with the product that awaits measuring, will shield door 2 pushes away to the below of sensor 7 that targets in place, sensor 7 feedback signal that targets in place makes locking cylinder 3 starts, 4 atress removals of wedge, works as guide surface 5 with after the bearing 8 contacts, the bearing 8 atress drives shield door 2 is close to mounting bracket 1, and then the realization is closed the door and is sealed.
