Abstract

A modularized external connection box comprises an outer casing, a fastener and a movable part. The faster comprises a screw and a fixed portion, and the fixed portion comprises an end cap and a throat. The screw penetrates out of the outer casing from one side of the outer casing and is locked with the throat of the fixed portion arranged on the opposite side of the outer casing, and the movable part is movably sleeved on the throat of the fixed portion, arranged between the end cap of the fixed portion and the outer casing and spaced with the same. A gap reserved between the movable part and the fixed portion provides a proper rotation space for the movable part after assembly, and too loose or tight assembly is avoided.

Description

The modularity external connection box

Technical field

The present invention relates to a kind of modularity external connection box, particularly a kind of modularity external connection box with the fastener that is spirally connected.

Background technology

For realizing numerous functions of computer, its main frame inside is equiped with various modular functional units.Produce and installation exercise for simplifying, each functional unit generally all is placed in a modularity external connection box, and then the interface unit by external connection box is connected the various functions of realization with other functional units.

At present, industry all adopts the movement parts such as all kinds of handles or control lever as the interface unit of modularity external connection box.Therefore, guaranteeing that the Function of movement parts is very important, is how movement parts reasonably to be fixed on the casing of modularity external connection box and serve as what want the angle at this.Market product normally carries out riveted with blind rivet to movement parts, makes it to be fixed with external connection box.Yet the riveted process is difficult to accurate control usually, may cause the tension that is connected between movement parts and the external connection box, is unfavorable for operating personnel's controlling movement parts.

Summary of the invention

Therefore, be necessary to provide a kind of can controlled motion spare with external connection box between the modularity external connection box that is connected distance.

A kind of modularity external connection box, comprise shell, fastener and movement parts, this fastener comprises screw and fixed part, fixed part comprises block and throat, described screw passes shell and sealed with the throat of the fixed part that is positioned at the relative opposite side of shell from a side of shell, and movement parts is movably set in the throat of fixed part, and movement parts separates the gap between the block of fixed part and shell and with block or the shell of fixed part.

Suitable rotation space is left for the movement parts after the assembling in gap between movement parts and the fixed part, avoids assembling too pine or too tight situation appearance.

With reference to the accompanying drawings, the invention will be further described in conjunction with concrete preferred embodiment.

Embodiment

See also Fig. 1, show the exploded view of modularity external connection box of the present invention, it comprises a shell 10,, a fastener 20 and a movement parts 30.In the present embodiment, shell 10 is a canister 10, and described movement parts 30 is leader 30.Certainly, movement parts 30 also can be the miscellaneous parts such as control lever.

Canister 10 forms the structure of a hollow by some top boards 11, base plate 13 and side plate, in order to hold each electronic device (not shown) of this modularity functional unit.The top board 11, base plate 13 and the left plate 12 that have only shown canister 10 among Fig. 1.In the present embodiment, canister 10 is the rectangular structure of a hollow.The top board 11 of canister 10 is extended by left plate 12 horizontal vertical.Top board 11 bends also horizontal buckling vertically upward first again and forms a step in the position away from left plate 12.Near left plate 12 places one first through hole 101 is arranged at top board 11.

Please consult simultaneously Fig. 2 and Fig. 3, fastener 20 comprises a screw 21, some packing rings 22 and a fixture 23.The spire 210 of screw 21 mates with the first through hole 101 sizes of canister 10 top boards 11, and it can just be rotated through from the first through hole 101.Packing ring 22 is one to be the panel beating material packing ring 22 of annular.Spire 210 excircles just in time can mate with the inner periphery of packing ring 22, so that spire 210 can pass through from the interior ring of packing ring 22.Fixed part 23 comprises a block 231 and one throat 232.Block 231 is hexagon, and every limit to hexagonal centre slightly indent make block 231 seem round and smooth.Block has a manhole (figure is mark) that runs through whole fixed part 23 in the middle of 231, and described manhole diameter is identical with spire 210 diameters.The interior week of through hole is with the screw thread that is complementary with spire 210, so that screw 21 can firmly be locked in the throat 232.The overall diameter of throat 232 is larger than the overall diameter of packing ring 22, and the two is all little than block 231 diameter, and larger than the diameter of the spire 210 of screw 21.

Have one second through hole 31 on the handle 30.The second through hole 31 diameters are less than the diameter of the block 231 of fixed part 23 and greater than the diameter of throat 232, so that fixed part 23 only has throat 232 can pass through the second through hole 31.

Please consult again Fig. 2 and Fig. 3, show the assembly drawing of two different embodiment of modularity external connection box of the present invention.When canister 10, fastener 20 and handle 30 threes assemble, the spire 210 of screw 21 passes the first through hole 101 on the canister 10 up, packing ring 22 is enclosed within on the spire 210 from top board 11 tops of canister 10, and handle 30 is enclosed within outside spire 210 and the packing ring 22 by the second through hole 31.The throat 232 of fixed part 23 penetrates 31 li of the second through holes, and locks together with spire 210, and finally is connected to the top of packing ring 22.Because the diameter of the second through hole 31 of handle 30 is the diameters that are slightly larger than the throat 232 of fixed part 23, therefore after screw 21 and fixed part 23 are fixing, handle 30 radially do not have limited.For handle 30 can freely not rotated axial also limited, need to guarantee that block 231 lower surfaces of fixed part 23 can not be pushed down handle 30 tightly, namely the length of throat 232 thickness that adds upper gasket 22 is larger than the thickness of handle 30.Comparison diagram 2 and Fig. 3, the handle 30 in Fig. 2 is thinner than the handle 30 of three li in figure, so the embodiment among Fig. 2 adopted two packing rings 22, and the embodiment among Fig. 3 has adopted three packing rings 22.Certainly, when handle 30 is enough thin, can not use packing ring 22.That is to say, can change the quantity of packing ring 22 in when assembling, increase or cancel a packing ring 22 and produce a height and increase and decrease the space, so that block a shot 231 lower surfaces and handle 30 upper surfaces leave a slight gap 40 all the time.The thickness in gap 40 is preferred so that handle 30 leaves suitable rotation space after assembling, avoids Tai Song or too tight situation to occur.
