Abstract
The utility model relates to a door plate fixed part having a grounding function. With the prior art, the door plate of a cabinet is usually fixed via a bolt, and then the cabinet realizes grounding via a grounding cable. In this way, the structure can not bear oversize weight. What is worse, the assembling and dismounting of the door plate are inconvenient as the grounding cable is required to be connected or disconnected. The utility model relates to a door plate fixed part having a grounding function. The door plate fixed part comprises a boss, a sinking table, an installing hole, and a spine. The door plate fixed part of the utility model simplifies the structure, realizes the reliable installation and grounding of the door plate having overlarge weight. Moreover, the installation and dismounting of the door plate are convenient. The production efficiency is improved and the door plate facilitates maintenance.
Description
Technical field
The utility model relates to a kind of cabinet door board fixing structure, particularly relates to the door-plate fixed structure that needs ground connection and need not use hinge.
Background technology
The door-plate of rack of the prior art is fixed with dual mode, and a kind of is to need the door of switch to use hinge and door lock to realize; Also have a kind of door-plate to fix; In use generally need not open, be generally used for some regulator cubicles, these door-plates are normally used bolt through fixing support; Be grounded through earth cable then; This structure has two shortcomings, and the one, door-plate fixed support intensity is limited, can not bear excessive weight; The 2nd, owing to need to connect and break off earth cable, door-plate assembling and dismounting are inconvenient.
Summary of the invention
Do not need the door-plate of frequent switch to this type, in order to overcome the deficiency of prior art, increase product reliability, make things convenient for installing/dismounting, improve product competitiveness, it is the purpose of the utility model that a kind of reliable easy door-plate fixed structure is provided.
The utility model solves the technical scheme that its technical problem adopted: 1, adopt mach fixture to gain in strength; 2, on fixture, realize the function of rack ground connection.The utility model is to come concrete the realization through following technical measures; A kind of structure of the door-plate fixture with grounding function; It is characterized in that described fixture is a kind of fixed component of type shape, comprise boss, heavy stand, installing hole and spine, described fixture is processed into by steel plate or shaped steel; The transverse gage of fixture can be designed as 15mm to 30mm according to cabinet dimensions; Fixture boss top can be designed according to the spacing of door-plate and rack to the height of bottom, is generally 20mm between the 50mm, the fixture longitudinal length at 50mm between the 200mm; At the boss center and heavy stand center, the two ends processing mounting holes of fixture, the diameter dimension in hole at ∮ 6.5mm between the ∮ 16.5mm; With fixture and rack and door-plate connection, bolt can be selected the standard component bolt of M6 to M16 through bolt; Around installing hole on the bottom surface of the middle part of fixture boss end face and two ends protrusion, process a plurality of spines with machine work; These spines can puncture rack and door-plate surface paint when mounted and embed rack cabinet and door-plate; Assurance is grounded; To between the 5mm, quantity can decide according to the size of fixture the height of spine at 2mm, and each face quantity is between 10 to 50; The heavy stand at the boss two ends, middle part of fixture and the heavy stand at the boss back side are used to bury the bolt head of installation; Machine the back fixture is heat-treated, surface hardening, hardness is at HRC40 to 60, and degree of depth 1.5mm electroplates anti-corrosion treatment to whole part at last again.
The good effect of the utility model is: simplify the structure, realized that the reliable installation of big weight door-plate, ground connection guarantee that easy accessibility has improved production efficiency simultaneously, is convenient to product maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the upward view of Fig. 1.
Each mark is represented the following meaning respectively among the figure:
1, boss; 2, heavy stand; 3, installing hole; 4, spine; The width of B, fixture; The height of H, fixture; The length of L, fixture.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Present embodiment is the door-plate fixture that is fit to be installed in the band ground connection in the regulator cubicle, and the rack height is at 2 meters, 0.8 meter of width, and door-plate weight is at 25 kilograms; Adopt the door-plate fixture of 6 band ground connection, each fixture is all formed by the structure that accompanying drawing provides, and comprises boss 1, heavy stand 2, installing hole 3 and spine 4, is processed into the fixture of type shape by the 20mm steel plate; It is of a size of width B=20mm, height H=30mm, length L=80mm, and each 3 hole of fixture processing, the hole dimension on both sides is ∮ 10.5mm; Use on the cabinet framework of M10 bolt, middle boss centre bore is processed into ∮ 8.5mm, with M8 bolt door-plate; Heavy stand 2 that height is 5mm of processing is used to imbed the M8 bolt head at boss 1 back side, around the installing hole 3 of fixture boss and bottom surface, two ends, processes spine; The spine height is at 2mm, and quantity is 30 in each face, heat-treats at last; With the fixture surface hardening, hardness is at HRC50, degree of depth 1.5mm; Again whole part is electroplated anticorrosion at last, actual installation is accomplished the test door-plate by reliable fixation, and grounding function is good simultaneously.
