Description

A kind of desk clock

Technical field

The utility model relates to a kind of desk clock, is meant the supporting structure of desk clock especially.

Background technology

At present, disclosed on the market desk clock, as Fig. 1, shown in, generally be support and base 102 formations by hour 100, straight-bar support 101 or spring suppport 101 ' or other fixed in shape.Because above-mentioned support fixed in shape, when support during higher or broad, shared packing and transport space are all bigger, and current society, the consumer is not only just given the correct time to the demand of desk clock, more be that requirement has ornamental and type toy, therefore the immutable support of existing shape is the demand that has been difficult to satisfy above-mentioned production, transportation and use.

The utility model content

For overcoming the above-mentioned defective of prior art, it is collapsible that the purpose of this utility model provides a kind of support, can change the desk clock of multiple shape.

For achieving the above object, the utility model provides a kind of desk clock, it comprises hour, chain stay, base, wherein chain stay is by the fitting chain sheet, intermediate chain sheet and the chain core that is fastenedly connected the chain sheet, spring, chain rivet reaches the keeper formation supporting with chain rivet, fitting chain sheet two ends and centre position respectively have a center hole, intermediate chain sheet two ends respectively have a center hole, the chain core is a circular cylinder, ring diameter is greater than the spring external diameter in it, spring inside diameter is greater than the chain shaft diameter, the chain shaft diameter is suitable with each chain sheet center hole aperture, the chain shaft length is greater than the thickness and the spring length sum of four chain sheets, spring length is greater than chain core length, concrete fit is: the center hole that at first a chain rivet is passed successively an outer chain sheet, the center hole of one inner chain sheet, the spring and the spring of ining succession pass the chain core together, pass the center hole of another inner chain sheet and the center hole of another chain sheet again, use at last one with the chain sheet of the supporting fastening chain shaft end of keeper of chain rivet, by chain sheet pressuring spring, spring tip is not exposed for the chain core, and each chain sheet is only as outer chain sheet or only as inner chain sheet; Secondly, the fitting chain sheet is folded in half into " ㄇ " font, its two perpendicular section is connected in the above described manner with the intermediate chain sheet, the one crosspiece with hour the base or end top margin all be connected by bolted.

The keeper two that above-mentioned chain rivet reaches and chain rivet is supporting is preferably screw and bolt.

Above-mentioned chain structure mainly is to utilize the spring of chain in-core when being subjected to the compressing of chain sheet, produce deformation, thereby produce the elastic-restoring force that reacts on the chain sheet, when the chain sheet be fixed spacing after, this restoring force makes two adjacent interior outer chain sheets compacted, friction factor between the chain sheet increases, the reverse friction force that makes the chain sheet be produced because of the desk clock self gravitation is enough to overcome the deformation requirement of the gravity that bears, and make the chain of this desk clock can not resemble in the daily life or can't be uprightly the common chain that arrives in the factory, typing.Simultaneously, when chain-sheet of chain is being subjected under the big external force effect such as manpower, when promptly oppositely friction force can't overcome this external force to the requiring of deformation, the chain sheet will be subjected to displacement, cause chain stay deformation, and, because the general characteristic of chain is the characteristic of remote transferring power, as long as external force is enough big, each chain sheet of entire bracket all might be subjected to displacement so, and, as long as external force acts on hour or base, just can make chain stay produce deformation.

The chain stay of gained desk clock both can be upright, collapsible, can change multiple shape, can also save a large amount of packings and transport space, has very high ornamental and type toy.

Embodiment

As shown in Figure 2, a kind of desk clock, comprise hour 1, chain stay 2, base 3, wherein chain stay 2, as Fig. 3,4, shown in 5, be by fitting chain sheet 21 ', intermediate chain sheet 21 and the chain core 22 that is fastenedly connected the chain sheet, spring 24, screw 23, bolt 25 constitutes, fitting chain sheet 21 ' two ends and centre position respectively have a center hole 21 ' 1, intermediate chain sheet 21 two ends respectively have a center hole 211, chain core 22 is a circular cylinder, ring diameter is greater than spring 24 external diameters in it, spring 24 internal diameters are greater than screw 23 diameters, screw 23 diameters are suitable with each chain sheet 21 center hole apertures, screw 23 length are greater than the thickness and the spring 24 length sums of four chain sheets 21, spring 24 length are greater than chain core 22 length, concrete fit is: as Fig. 2, shown in Figure 5, at first a screw 23 is passed successively the center hole 211 of an outer chain sheet 21, the center hole 211 of one inner chain sheet 21, the spring 24 and the spring 24 of ining succession pass chain core 22 together, pass the center hole 211 of another inner chain sheet 21 and the center hole 211 of another chain sheet 21 again, the chain sheet 21 of last bolt 25 holding screws 23 ends, by chain sheet 21 pressuring springs 24, spring 24 terminations are not exposed for chain core 22, and each chain sheet 21 is only as outer chain sheet or only as inner chain sheet; Secondly,, fitting chain sheet 21 ' is folded in half into " ㄇ " font, its two perpendicular section is connected in the above described manner with intermediate chain sheet 21 as Fig. 2, shown in Figure 4, the one crosspiece and hour 1 base or base 3 top margins all be fastenedly connected by bolt 10.

Use screw 23, bolt 25 to be fastenedly connected, can adjust spring 24 deformation quantities, thereby adjust the friction factor between two adjacent inside and outside chain sheets, adjusting makes chain 2 produce the size of the required external force of identical deformation, like this can be at dissimilar consumers, unscrew such as bolt, child and female consumer just can be easier to folding chain 2, otherwise male sex consumer then.Simultaneously, rivet, snap ring is spacing etc. connects rivet length dimension, the bayonet socket position that fastening means all needs strict control to cooperate with chain core 22, chain leaf length, after using a period of time, cooperating can be loosening and influence the stability of desk clock support: and screw 23, bolt 25 both can constantly have been adjusted the size that cooperates with chain core 22, chain leaf length, still the standard component that is seen everywhere on cheap, the market, simplify production process greatly, reduce production costs.
