Abstract

The utility model relates to an improved structure for a combined dog for fastening. A fixed group and a movable group are respectively fixed the end sides of two different wainscots, and the fixed group is provided with pins which can make the dog board of the movable group hooked, clamped and combined. The movable group can use an actuating lever to drive an eccentric wheel to rotate, and the eccentric wheel is sheathed in the circular hole of the dog board through a convex circular wheel. The actuating lever can drive the dog board, and thereby, a clamping dog on the dog board can be tightly buckled on the pin of the fixed group. The structure of the utility model can make the wainscots closed well, and thereby, the better thermal insulation effect and the better airtight effect are obtained. The utility model is especially suitable for the refrigerator needing the good thermal insulation property.

Description

The improvement structure of the primary and secondary clasp that a kind of fastening is used

The utility model relates to a kind of improvement structure of primary and secondary clasp, especially a kind of double buckle hook structure that uses on the wallboard of freezer.

At present, the schematic perspective view of normally used double buckle hook structure as shown in Figure 7.This primary and secondary clasp 14 mainly is made up of a mother buckle 141 and sub-fastener 142.Wherein mother buckle 141 is with an interior hexagonal axis 144 an envelope hook 143 to be installed in a housing 145, and sub-fastener 142 then is provided with a fixture block 147 in a housing 146, can hook with hook 143 to cooperate.When mounted, son, mother buckle 141,142 are installed in respectively on two blocks of adjacent freezer plates.Yet the primary and secondary clasp of said structure still can't make and obtain better heat insulation, airtight effect between the wallboard.

The purpose of this utility model is to provide the improvement structure of the primary and secondary clasp that a kind of fastening uses, and makes to have closed preferably, effect of heat insulation between wallboard.

The purpose of this utility model is achieved in that in the improvement structure of the primary and secondary clasp that a kind of fastening is used, have fixing group and movable group, they are separately fixed at the end limit of two different wallboards, and fixedly group is provided with the tip that the hook plate that can make movable group gives the grab engaging.Movable group drives eccentric wheel by starting bar and rotates, and eccentric wheel is enclosed within the circular port of a hook plate by the circular wheel of protruding.Eccentric wheel is provided with projection and can contacts with the bossy body of hook plate, makes hook plate be activated bar and drives indirectly.Hook plate is provided with the grab on the tip that can closely be fastened on fixing group.

Owing to adopt such scheme, fixing group is separately fixed on two different wallboards with the activity group, is provided with by the tip of snapping in fixing group, makes the movable hook plate of organizing buckle with it.The activity group itself is to drive a hook plate indirectly by starting bar to rotate, hook plate can snap onto earlier on the tip of fixing group, and hook plate itself is driven indirectly by an eccentric wheel, therefore can continue to drive eccentric wheel by starting bar, make hook plate more closely fastening on the tip of fixing group, make wallboard have closed preferably, effect of heat insulation.

The utility model structure shown in Fig. 1,2 includes members such as fixing group 1, movable group 2.

Fixing group 1 is fixed on the end limit of wallboard usually, can be as shown in the figure, be fixed on the wallboard by two plates, and two plates respectively are provided with tip hole 11, tip hole 11 can have fixed effect preferably for making fixing group 1 with wallboard for the tip 12 location, and the plate of fixing group is provided with more convex body, when making the fixing plate of organizing be fixed on wallboard, better positioning effect is arranged.

Movable group 2 also is fixed on the end limit of the adjacent wallboard of freezer by convex body 26, as shown in the figure, be combined into one with setting elements such as bolt 21 between two plates, and this two plate respectively is provided with axis hole 22 and can supports eccentric wheel 23 and hook plate 24 to rotate, and is driven by a starting bar 25; Eccentric wheel 23 protrudes with one and becomes eccentric circular central siphon 231 external diameters to be enclosed within the axis hole 22 makes position rotating, circular central siphon 231 internal diameters are the Cheng Feizheng toroidal then, can cooperate driven rotary for starting bar 25, eccentric wheel 23 has the circular wheel 232 of protrusion, can cooperate in the circular port 241 that is contained in plate 24 by circular wheel 232, and eccentric wheel 23 has the projection 233 of protrusion, can contact bossy body 242 at hook plate 24 by projection 233, forms the motion of eccentric wheel 23 and hook plate 24; Hook plate 24 is inserted for circular wheel 232 cooperations of two eccentric wheels 23 by circular port 241, and two eccentric wheels 23 slightly become tight friction to contact with 24 of hook plates, this hook plate 24 is provided with the bossy body 242 of protrusion, projection 233 by eccentric wheel 23 can contact with it, do the motion of the two, hook plate 24 is provided with grab 243, this grab 243 can hook the tip 12 of fixing group 1, for making hook plate 24 that locating effect be arranged when opening, hook plate 24 can be established location hook 244 in addition, can be hooked on the setting element 21 by location hook 244 when hook plate 24 is opened; Starting bar 25 has non-just round pole face, can coincide with central siphon 231 internal diameters of eccentric wheel 23, rotates in order to drive eccentric wheel 23.

Fig. 3,4 be depicted as 2 one-tenths of fixedly group 1 of the present utility model and movable groups near the time situation, at this moment, hook plate 24 with fix that to organize 1 12 one-tenth first section at the tip approaching.

See also shown in Figure 5ly, when starting bar 25 continued to drive eccentric wheels 23 and rotates, hook plate 24 can closely be snapped onto on the tip 12 of fixing group 1 by grab 243, and then wallboard can have airtight effect preferably.

See also shown in Figure 6ly, when hook plate 24 need not fasten, can as shown in the figure hook plate 24 be stood, and be relied on the setting element 21 by location hook 244, then hook plate 24 can become to stand parked.

Member of the present utility model can make adjacent wallboard that airtight effect is preferably arranged, and fixes group and establish more convex body with movable group, therefore, and also has bond strength preferably between wallboard, and the two does not have the problem of coming off.
