Abstract

The invention provides a modular external enclosure. The external enclosure comprises a shell, a buckle and a moving part, wherein the buckle comprises a bolt and a fixing portion; the fixing portion comprises a nut cap and a throat; the bolt passes through the shell from one side of the shell and is locked with the throat of the fixing portion on the other side of the shell; the moving part is movably sleeved on the throat of the fixing portion; the moving part is arranged between the nut cap of the fixing portion and the shell; and Teflon paste is arranged in the position where the bolt and the throat are locked to enhance connection of the bolt and the throat. The external enclosure has the following beneficial effects that the Teflon paste adjoins the contact portion of the bolt and the throat in the bolt and throat locking process so that the bolt and the throat can be tightly locked to prevent the buckle from getting loose.

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, for the modularity external connection box is operated, usually can a connection piece be set at the modularity external connection box, and fix a movement parts at connector, be used for rotating around the connector axle center.The rotation meeting of movement parts produces the effect of power in tangential direction to connector.Because the rotation of movement parts is frequent, easily causes getting loose of connector, this can directly affect the performance of movement parts.

Summary of the invention

Therefore, be necessary to provide a kind of modularity external connection box that can prevent that connector from getting loose.

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, and 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, movement parts is between the block and shell of fixed part, and wherein screw and the locked position of throat have the anti-glue that falls to strengthen being connected of screw and throat.

This anti-glue that falls abuts against the contact site of the two in the sealed process of screw and throat, so that screw and throat can be closely sealed, prevent that fastener from getting loose.

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, one fasteners 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 is formed 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.

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, show the partial enlarged drawing of modularity external connection box of the present invention.Point has the anti-glue 211 that falls on the spire 210 of fixed part 23.This anti-glue 211 that falls can be put any position that is threaded one side at spire 210.The described anti-glue 211 that falls is the high elasticity abrasion-proof texture coatings that produce with the high-performance fine powder, be comprised of polymer resin, hot elastomer, polyvinyl chloride (PVC), polyethylene (PE), nylon (11 types or 12 types), mixed solvent, polypropylene (PP) and polyester etc., working temperature is generally-60 ° of C to+180 ° of C.

Please consult again Fig. 3, show the side sectional view after modularity external connection box of the present invention is assembled.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.When spire 210 screws in throat 232, the anti-glue 211 that falls is applied to the contact position of spire 210 and throat 232, so that spire 210 is closelyr sealed with throat 232.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 push down handle 30 tightly, be the thickness that thickness that the length of throat 232 adds upper gasket 22 is larger than handle 30, namely 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.Handle 30 can rotate take throat 232 as the axle center well, and because the anti-glue 211 that falls has high-wearing feature and high mechanical elasticity, after spire 210 and fixed part 23 are sealed, can solve race that becoming flexible of screw 21 that the rotation because of handle 30 brings cause, emit, fall apart, the phenomenon such as leakage.Even throat 232 often be subject to from handle 23 from the active force on the tangential direction, also can keep closely sealed with screw 21, can keep the proper motion of handle 30.
