A kind of tap water watch glasses
Technical field
The utility model relates to a kind of tap water watch glasses.
Background technology
Existing tap water watch glasses mounting means is generally and is threaded, and concrete screwing position mainly contains following several: 1, mounting hole site is in water meter cover both sides, and this connected mode takes up room greatly, in narrow space, be just not suitable for this connected mode; 2, utilize the copper band having beaten multiple hole to connect, the operation of this connected mode is many road auger shell pit, also reduces production efficiency unsightly; 3, utilize pad to fixedly mount, due to the not high reason of machining precision, the pad quantity needed for installing cannot be determined, add uncertainty.
Utility model content
The utility model object be for prior art exist defect provide one be convenient to install, tap water watch glasses attractive in appearance.
The utility model for achieving the above object, adopts following technical scheme: a kind of tap water watch glasses, comprises and covers the water meter cover that water meter is outer, be fixedly connected with water meter; At described water meter cover inside surface, the junction of water meter is provided with to organize spring tooth more, described spring tooth comprises bow-shaped support and is fixed on described bow-shaped support two ends, the upper spring tooth integrally formed with described bow-shaped support and lower spring tooth; Described lower spring tooth fixes the raised position of water meter bottom it, prevents water meter cover from upwards departing from water meter; Described upper spring tooth fixes the copper band in water meter portion thereon, prevents water meter cover from moving down.
Preferably, described lower spring tooth adopts wedge shape spring tooth.
Preferably, described bow-shaped support upper end is close to described water meter cover and is arranged, and leaves space between lower end and described water meter cover.
The beneficial effects of the utility model: adopt many group spring teeth to install water meter cover, fixing compact, and do not need other instruments when mounted, convenient operation; By spring tooth as inside water meter cover, not only make this water meter cover good looking appearance, and decrease water meter cover and take up room; The spring tooth adopted is integrally formed, decreases processing technology; The press-bending height of Elastic Teeth is flexible, has adaptive character to copper band height, can aim at water meter numeral by adjusting angle.
Accompanying drawing explanation
Fig. 1 the utility model using state figure.
Embodiment
Fig. 1 is a kind of tap water watch glasses, comprises and covers the water meter cover 1 that water meter 2 is outer, be fixedly connected with water meter 2; At described water meter cover 1 inside surface, the junction of water meter 2 is provided with to organize spring tooth more, described spring tooth comprises bow-shaped support 5 and is fixed on described bow-shaped support 5 two ends, the upper spring tooth 3 integrally formed with described bow-shaped support 5 and lower spring tooth 4; Described lower spring tooth 4 fix water meter 2 in its bottom raised position, prevent water meter cover 1 from upwards departing from water meter 2; Described upper spring tooth 3 fixes the copper band in water meter 2 portion thereon, prevents water meter cover 1 from moving down.Described lower spring tooth 4 adopts wedge shape spring tooth, and described bow-shaped support 5 upper end is close to described water meter cover 1 and is arranged, and leaves space between lower end and described water meter cover 1.
Gradually near water meter 2 upper end bottom water meter cover 1, when lower spring tooth 4 touches water meter 2 upper end, water meter 2 props up lower spring tooth 4, lower spring 4 is made laterally deformation to occur, bow-shaped support 5 lower end struts to the space between bow-shaped support 5 and water meter cover 1 together along with lower spring tooth 4, be convenient to water meter cover 1 continue to entangle water meter 2 downwards, when upper spring tooth 3 soon blocks the copper band of water meter 2 upper end, suitable rotating water watch glasses 1, water meter cover 1 viewing area is made to aim at water meter numeral, continue again to press down water meter cover 1, until lower spring tooth 4 just in time props up the lower end raised position of water meter 2, limit water meter cover 1 to move up, now going up spring tooth 3 enters in the copper band of water meter 2 upper end completely, limit water meter cover 1 to move down, water meter cover is with regard to installation.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
