Embodiment

With reference to the accompanying drawings and examples, the utility model is described in detail.

The flow computer assembling case of easy access, as shown in Figure 1 and Figure 2, including bottom plate 1, the weldering of the upper surface both sides of bottom plate 1 Connect and be fixed with side shield 11, rear baffle, rear baffle and two top bolts of side shield 11 are welded with rear side of the upper surface of bottom plate 1 Top plate 14 is fixed with, its bottom plate 1, side shield 11, top plate 14 are aluminum alloy plate materials, so that 1, two side shield 11 of bottom plate, The casing of top plate 14, rear baffle splicing composition front end face hatch frame, the opening terminal bolt is fixed with front apron 13, by front baffle board 13 or so are divided into two halves, and half offers display screen windows 15 and multiple button grooves 16, and second half offers access panel 21, Access panel 21 is detachably provided with maintenance door 22；Maintenance door 22 is unloaded when needing maintenance, by access panel 21 in assembling case The circuit in portion is overhauled, so as to provide facility for maintenance.

As shown in Figure 2 and Figure 3, for the side of maintenance door 22 integrally formed with two grafting blocks 27, grafting block 27 can be flat Rectangular block, the side wall of access panel 21 offer the inserting groove 28 coordinated with grafting block 27, and the section of inserting groove 28 is in V-shape, so that After grafting block 27 is inserted in inserting groove 28, maintenance door 22 has the ability to be turned an angle with grafting block 27 for center of rotation； As shown in Figure 2, Figure 4 shows, the opposite side of maintenance door 22 is through groove 23 is offered, and about 23 both sides point in groove for the internal face of maintenance door 22 Sliding wall 24 is not welded with, is slid between two sliding walls 24 and is connected with latch segment 25, and the welding of the side wall of access panel 21 is solid Surely there is the locking bar 26 coordinated with latch segment 25, wherein locking bar 26 is flat bonding jumper, latch segment 25 is rectangular metal block, It offers the notch 254 equal with the locking thickness of bar 26 towards locking bar 26 one end, so as to be matched somebody with somebody by the notch 254 of latch segment 25 Close maintenance door 22 and form U-shaped folder mouth clamping locking bar 26；In fixed maintenance door 22, grafting block 27 is directed at inserting groove 28 and inserted Enter, be that center of rotation rotates maintenance door 22 to being completely in access panel 21 with grafting block 27, along sliding wall 24 and towards locking The slide-and-lock block 25 of bar 26, it is in bar 26 is locked in the notch 254 of latch segment 25, so as to complete the fixation of maintenance door 22； When dismantling maintenance door 22, along sliding wall 24 and away from the locking slide-and-lock block 25 of bar 26, maintenance door 22 is turned out, by grafting block 27 in inserting groove 28 by extracting and removing maintenance door 22.

Be limited the sliding trajectory of latch segment 25 processed, as shown in figure 4, the sliding opposite face of wall 24 opens up respectively along its center line direction There is chute 241, latch segment 25 slides the slipping part 242 coordinated integrally formed with chute 241, and wherein slipping part 242 is side The rectangle being bonded with latch segment 25, so as to cause latch segment 25 to be only capable of along sliding between slipping part 242 and chute 241 The length direction of wall 24 slides.

To avoid the skidding distance of latch segment 25 excessive, it is caused to depart from sliding wall 24, as shown in Figure 4, Figure 5, two by both ends Away from locking bar 26 between individual sliding wall 24（It is shown in Fig. 2）It is provided with limiting plate 243, the two side of limiting plate 243 is respectively with two Individual sliding wall 24 is welded and fixed, so as to limit the skidding distance of latch segment 25 backward；The outside wall surface of latch segment 25 is integrally formed with applying Power block 251, force-application block 251 is the dome-type projection for protruding from the outside wall surface of latch segment 25, so as to the groove 23 with force-application block 251 The skidding distance of side wall limitation latch segment 25 forward；Force-application block 251 also has simultaneously provides a force for slide-and-lock block 25 The effect of point, facility is provided for slide-and-lock block 25.

It is as shown in Figure 4, Figure 5, two sliding walls 24, spacing to avoid the dirts such as dust from being entered by groove 241 in assembling case Dust board 244 is provided between plate 243, the side wall of dust board 244 3 is welded and fixed with two sliding walls 24, limiting plate 243 respectively, The surface of dust board 244 is bonded with latch segment 25, and 243, two dust board 244, limiting plate sliding walls 24 form a four sides and sealed Structure, only a surplus opening are blocked by latch segment 25, so as to effectively prevent dust from being entered by groove 23 in assembling case.

To avoid because improper slip occurs for latch segment 25, it is caused to depart from locking bar 26, it is as shown in Figure 4, Figure 5, spacing Be provided with compression spring 252 between plate 243 and latch segment 25, the both ends of compression spring 252 respectively with limiting plate 243, latch segment 25 Be welded and fixed, its in the raw under, locking bar 26 be in the notch 254 of latch segment 25（Refer to the stationary state of maintenance door 22 Under）, so as to utilize the improper slip of the elastic power restriction latch segment 25 of compression spring 252.

As shown in Figure 2, Figure 4 shows, latch segment 25 towards locking bar 26（It is shown in Fig. 2）Offer inclined plane 253, installation and repairing Door 22 is during center of rotation rotates with inserting groove 28, and inclined plane 253 contacts at locking bar 26 edge, because normal pressure is former Reason, locking bar 26 produce the reaction force perpendicular to inclined plane 253 to latch segment 25, are decomposed through stress, partly push dynamic locking Block 25 slides away from locking bar 26, and now compression spring 252 is in contraction state, when locking bar 26 is in latch segment 25 and maintenance When in the jaws of door 22, latch segment 25 is no longer influenced by the reaction force of locking bar 26, and compression spring 252 discharges elastic potential energy and promoted Latch segment 25 slides towards locking bar 26 and clamps locking bar 26；So as to when closing maintenance door 22, be slided without force in addition Latch segment 25, facility is provided for closure maintenance door 22.

To avoid because groove 23 influences the aesthetic property of assembling case front end face, as shown in Figure 6, Figure 7, the lower wall of groove 23 is hinged There is cover board 231, so as to there is cover board 231 to cover groove 23, a more complete front end face is provided for assembling case；For ease of Cover board 231 is opened, the edge of groove 23 offers the overall deep-slotted chip breaker 232 in 1/4 ball-type, and the deep-slotted chip breaker 232 is available for a hand Finger stretches into, so as to provide a point of application to open cover board 231；To avoid the unnormal unlocking of cover board 231, cover board 231 The pin joint of groove 23 is provided with torsion spring 233, torsion spring 233 descends cover board 231 to close the openend of groove 23 in the raw.

Described above is only preferred embodiment of the present utility model, and the scope of protection of the utility model is not limited merely to Above-described embodiment, all technical schemes belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
