Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing.

As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 9, a kind of novel switched magazine, including upper frame body 1 and lower case 2, The upper frame body 1 is detachably connected by connecting elements 3 and lower case 2, in the technical scheme, the preferably described connection structure Part 3 includes the nut 31 of attachment screw 30 and adaptation locking attachment screw 30, using the assembly side of attachment screw 30 and nut 31 Formula can be further simplified the process of installation, be easily installed or dismantle.The inner sidewall of the upper frame body 1 is equipped with for installing spiral shell Mother 31 hollow card column 10, hollow card column 10 hollow shape adaptation nut 31 shape so as to which nut 31 is clamped in In empty calorie column 10, and the attachment screw 30 is threadedly coupled after the hollow structure of hollow card column 10 with the realization of nut 31, is twisted The head for being tightly connected attachment screw 30 after screw 30 is then pressed on the edge of hollow card column 10, enables upper frame body 1 and lower casing Body 2 is realized detachably connected.In addition, for convenience attachment screw 30 and nut 31 connection, in the present embodiment, it is described on Framework 1 is also pre-installed by bayonet unit 8 and lower case 2, and the benefit of pre-installation is that attachment screw 30 is aligned The position of nut 31 is unlikely to relocate the position of nut 31 again.And bayonet unit 8 includes fixture block 80 and adaptation and fixture block 80 The hook 81 of clamping, fixture block 80 are equipped with installation inclined-plane 800, and specifically, the quantity of fixture block 80 is three, accordingly hook 81 It is three, the fixture block 80 is set in lower case 2, and the hook 81 is set on upper frame body 1.When installation, fixture block 80 is one by one first The position of corresponding hook 81, it is then that upper frame body 1 is mobile toward the direction of lower case 2, when the inner wall of upper frame body 1 and the peace of fixture block 80 When filling inclined-plane 800 and contacting, due to upper frame body 1 blocking and fixture block 80 is squeezed so that inwardly flexible deformation occurs, block Block 80 stores the elastic potential energy expanded outwardly after flexible deformation occurs, and continues upper frame body 1 working as fixture block toward the movement of lower case 2 80 when being moved to the position of hook 81, and departing from the contact of upper frame body 1, the elastic potential energy stored before fixture block 80 obtains fixture block 80 To release, caught on after fixture block 80 being expanded outwardly so that flexible deformation, fixture block 80 be overcome to expand outwardly by hook 81, from And the realization of upper frame body 1 is connect with the pre-installation of lower case 2.When needing to dismantle upper frame body 1, fixture block 80 need to be only pressed inside The opposite direction of upper frame body 1 toward lower case 2 is pulled out to the disassembly that upper frame body 1 Yu lower case 2 can be realized afterwards.

As shown in Fig. 2, Fig. 4, Fig. 5 and Fig. 8, the surrounding side wall of the upper frame body 1 is equipped with several upper half-round slots 4, In In the present embodiment, the upper half-round slot 4 there are three parallel arrangement is set in the one side wall of upper frame body 1, is then arranged two on other side walls The upper half-round slot 4 of a parallel arrangement, in order to when encounter number of electrical lines it is more when the trend of electric wire can be better distributed, Prevent electric wire confusion.The lower half circular groove 5 of corresponding upper half-round slot 4, the upper frame body are then equipped on the side wall of the lower case 2 1 forms the circular hole 6 passed through for electric wire with upper half-round slot 4 after the assembly of lower case 2 and lower half circular groove 5, and in the mistake of actual production Cheng Zhong, the movable plate 60 that masking circular hole 6 is typically provided in circular hole 6 and can be cracked, user can go to determine to make according to the quantity of electric wire With how many a circular holes 6, the circular hole 6 on the same face can be only used, the circular hole 6 on two opposite faces also can be used, this When movable plate 60 crack can supply lines pass through, and other it is useless to circular hole 6 then covered by movable plate 60, prevent other Impurity such as dust or wall ash enter in lower case 2.Specifically, the movable plate 60 and the lower half circular groove 5 of lower case 2 are integrated Structure depanning simultaneously, it is easy to produce.It needs exist for further illustrating, the movable plate 60 cracked refers to activity Then plate 60 can be separated by applied force with lower half circular groove 5, the movable plate 60 after cracking no longer is connect with lower half circular groove 5, thus Circular hole 6 is enabled to be used for the interspersed of electric wire.It can be inserted into cable conduct 9 in the circular hole 6 after movable plate 60 in addition, cracking to prevent electricity Line skin breakage effectively acts as the effect of protection electric wire.

As shown in Figures 3 to 5, the junction between the upper half-round slot 4 and upper frame body 1, lower half circular groove 5 and lower case 2 Between junction be equipped with the sliding slot 7 for preventing surfaces of wires from rupturing, sliding slot 7 is for smooth fillet, so as to do To in Mold Making formed pull the wire position be it is smooth, reduce rubbing between electric wire and upper frame body 1 or lower case 2 Power is wiped, the epidermis for destroying electric wire in pull the wire is prevented, prevents from leaking electricity.

As an improvement, as shown in Figure 6 and Figure 7, the lower case 2 is equipped with the top pillar 20 for binding nut 31, described The adaptation of top pillar 20 is inserted into hollow card column 10, and the nut 31 is located at the top of top pillar 20, and top pillar 20 is inserted into hollow card column The top of nut 31 toward hollow card column 10 is held out against after 10, thus realize the clamping to 31 upper and lower ends of nut, and 31 quilt of nut After clamping, so that attachment screw 30 will not there is a phenomenon where sliding teeths when connecting or dismantle with nut 31.Existing switch magazine one There is sliding teeth situation in denier, and the entire magazine that switchs all is not dismantled, and can only be tolled breakdown by way of demolishing walls, very inconvenient, and The increased top pillar 20 of the utility model institute is for secondary fixture nut 31, so that the tightening in attachment screw 30 of nut 31 in fact Or attachment screw 30 will not be followed to rotate during unscrewing, to play the role of preventing sliding teeth.

In conclusion the utility model is formed using upper frame body 1 and 2 two parts of lower case, upper half-round slot 4 and lower half circular groove 5 form the circular hole 6 that can be inserted into cable conduct 9, without installing connection accessory again, save time and the cost of assembly, Improve the efficiency of installation.In addition, the top pillar 20 of the utility model plays the role of secondary fixation to nut 31, connection spiral shell is prevented There is the case where sliding teeth in nail 30.

The preferred embodiments of the present invention have been described in detail above.It should be appreciated that the ordinary skill people of this field Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks Technical staff passes through logic analysis, reasoning or limited reality according to the design of the utility model on the basis of existing technology in domain Available technical solution is tested, it all should be within the scope of protection determined by the claims.
