Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.
Please consult Fig. 1, Fig. 2 and Fig. 3 together, the utility model sectional shelf-unit comprise a metallic support 10 and with the combined shielding case 20 of this metallic support 10.
See also Fig. 2, described metallic support 10 has a substrate 11, the middle part of the and arranged on left and right sides edge of this substrate 11 and the middle part of posterior lateral margin all form screens 12 to the middle part of described substrate 11 depression, the middle part of described substrate 11 cephalolateral margins has extended to form first location division 13 downwards, offers a jack 131 on this first location division 13.Respectively there is one second location division 14 both sides of described first location division 13, and this second location division 14 has a criss-cross positioning head 141, offers location hole 142 on the described positioning head 141.Be connected by a connecting rod 17 between described first location division 13 and described second location division 14, described first location division 13 and second location division 14 are arranged side by side and the end of described first location division 13 and second location division 14 all has a linking arm 16 that is connected on the strip 15, make that whole metallic support 10 can be one-body molded by a mold.
See also Fig. 3, described shielding case 20 has a tabular screening cover 21, and each prolongs the middle part of the and arranged on left and right sides edge of this screening cover 21 to evagination and be formed with a location hook 22, and this positioning hanger 22 is the I-shaped shape substantially.The middle part of the forward and backward both side edges of screening cover 21 has outwards protruded out preceding support column 23, back support column 24 respectively.Described screening cover 21 the both sides of back support column 24 outwards respectively protruded out a card 25 respectively.The both sides of the posterior lateral margin of described screening cover 21 respectively protrude out a linking arm 27 that is connected on the strip 26, thereby whole shielding case 20 can be one-body molded by a mold.
Please consult Fig. 1, Fig. 2 and Fig. 3 together, described shielding case 20 is combined on the described metallic support 10, the positioning hanger 22 of the and arranged on left and right sides of described shielding case 20 bends the back holding respectively in the screens 12 of the and arranged on left and right sides of described metallic support 10, be plugged in after preceding support column 23 bending of described shielding case 20 in the jack 131 on first location division 13 of described support, the back support column 24 bending back holdings of described shielding case 20 are in the screens 12 of the rear side of described metallic support 10.The card 25 that the rear end of the left and right lateral margin of described screening cover 21 protrudes out is replaced on the substrate 11 of described metallic support 10 after bending respectively.Described shielding case 20 begins described strip 15,26 to cut off from the front end that links to each other with connecting rod 17 with cutting tool after making up with described metallic support 10 again.
