Description

Component installs rack

Technical field

The utility model is related to Installation cabinet technical field, specifically be a kind of component installation rack.

Background technology

In the prior art, in order to realize that installation is orderly, power supply is convenient and be easy to management etc., electronic component is typically unified to pacify In a component installation rack.

Component installation rack generally there are following deficiency in the prior art：

1. the top assembly of component installation rack is directly one block of sheet material, sheet material is not provided with the hole of threading, so, It is very inconvenient when needing wiring to be passed through from component fitting machine cabinet top parts；

2. the base assemblies of component installation rack are also directly one block of sheet material, cause base assemblies structural strength low, Deformation is also easy to produce in transportation, influences the normal use of component installation rack；

Together with 3. the vertical beam of component installation rack is welded to crossbeam, so, it must be welded into assembling Type, cause general frame assembling inconvenience.

4. the plate of side plate one of component installation rack is that screw-driving is fixed, so, needing to unload lower side panel inspection cabinet Dismounting trouble, is caused inconvenient for use during internal structure.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of convenience in top trace and effectively avoids dust The component entered from component fitting machine cabinet top installs rack.

In order to solve the above technical problems, component installation rack of the present utility model, including four vertical beams；Four described perpendicular Beam, which is square, to be set and fixes to form installation cabinet framework by more crossbeams；Top plate is connected with the top of installation cabinet framework Component, it is characterised in that the top plate member includes top plate, hairbrush and the ventilating board with air port, and the top plate is provided with the One resigning mouthful and the second resigning mouthful, the ventilating board are connected to the first resigning mouthful opening position, and the hairbrush is connected to the second resigning Mouth opening position.

After said structure, have the following advantages that：So, passed through when the second resigning mouthful is used to wiring, it is convenient Connected up at the top of installation cabinet framework, in addition, hairbrush is connected to the second resigning mouthful opening position, the hair of such hairbrush is due to being soft , it can be stepped down to line, and the elasticity of the hair of hairbrush can wrap up line, so as to avoid dust from entering to cabinet from top Internal portion.

The bristle of the hairbrush be arranged in parallel with top plate, and the ventilating board is used to install blower fan.

The top of the vertical beam is provided with cavity, and installation contiguous block is fixed with cavity, and the top plate leads to installation contiguous block Cross mode connects for screw.So, facilitate the connection of top plate, improve efficiency of assembling.

The side wall of the cavity has the breach that the axis direction along vertical beam is set.So, the presence of breach so that cavity Size it is adjustable, it is convenient that contiguous block is fixedly mounted when installing contiguous block and being put into cavity.

The outside edge of the installation contiguous block is provided with chamfering, when the installation contiguous block is located in cavity, it is described The side wall of angle and cavity forms the molten groove of welding, and the installation contiguous block is welded in cavity.So, when installation contiguous block is to weld Form when fixing, convenient welding, welding can be made more firm.

The cross section of the vertical beam is step, the vertical beam of step have be used for first confined planes spacing to crossbeam and Second confined planes, the crossbeam and the first confined planes or the second confined planes push against.So, can be with when vertical beam and crossbeam assemble Position-limiting action is played, improves efficiency of assembling.

Four sides of the top plate have the flanging rolled over downwards, and the flanging pushes against with corresponding beam side wall.So, flanging On the one hand the structural strength of top plate is improved, in addition, flanging pushes against with corresponding beam side wall, dust can be avoided to enter.

The inner side of crossbeam at the top of installation cabinet framework has a sinking step, and the top plate is towards installation cabinet framework side The end of the flanging of portion one end is provided with flange, and the flange be arranged in parallel with top plate, and the flange pushes against with sinking ledge surface. So, flange not only acts as the effect of roof supporting, also acts as the effect for further preventing that external dust from entering.

The bottom surface of the top plate is provided with reinforcement, and the reinforcement extends to the other end, the reinforcement by one end of top plate Muscle pushes against between flange and top plate.So, reinforcement plays a part of strengthening the structural strength of top plate, avoids due to structure There is the defects of recessed in insufficient strength.

Four vertical beams are respectively the first vertical beam, the second vertical beam, the 3rd vertical beam and the 4th vertical beam, first vertical beam, Second vertical beam and crossbeam composition side frame, the 3rd vertical beam, the 4th vertical beam and crossbeam composition side frame；It is connected with the middle part of the side frame Middle beam part, the component installation rack also include the first lateral plate component and the second lateral plate component, the first side plate group One end of part and the crossbeam clamping positioned at side frame bottom, the other end and the middle beam part interlocking of first lateral plate component, institute State the second lateral plate component and middle beam part clamping, the other end of second lateral plate component and the cross beam lock at the top of side frame Connect.So, interface arrangment is employed with interlocking to coordinate, when needing to unload the structure in lower side panel inspection cabinet, easy disassembly.

The lower section of first lateral plate component and the second lateral plate component is provided with the card adapter plate protruded down, institute's middle beam part There is clamping step, the card adapter plate and clamping step clamping with the crossbeam positioned at side frame bottom.So, it can be made in clamping When than stronger, avoid the first lateral plate component and the second lateral plate component from departing from.

It is provided with positioned at the crossbeam installed at the top of cabinet framework and between the crossbeam of installation cabinet framework bottom along vertical The angle gauge that direction is set, is provided with the interface arrangment to cooperate between the crossbeam and angle gauge, the crossbeam passes through spiral shell with angle gauge Line part connects.So, angle gauge plays a part of convenient installation electronic component, also, phase interworking is provided between crossbeam and angle gauge The interface arrangment of conjunction, so, when assembling crossbeam and angle gauge, can first clamping, tightened again by being spirally connected afterwards, it is convenient for assembly.
