Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
The new water meter protective cover structural representation that Fig. 3 provides for the present embodiment, as it is shown on figure 3, the new water meter protective cover that this utility model provides, including upper cover 1 and ring protection cover body 2；Described upper cover 1 one edge is provided with breach 101, described breach 101 be respectively provided on two sides with cylindrical bump 102；Described ring protection cover body 2 one edge is provided with fixed block 201, and the distance of described fixed block 201 both sides is not more than the distance of described breach 101 both sides；The both sides of described fixed block 201 are provided with arc gap 202, and the diameter of described arc gap 202 is not less than the diameter of described cylindrical bump 102；When described cylindrical bump 102 loads described arc gap 202, described upper cover 1 overturns around described cylindrical bump 102；Described upper cover 1 is when described cylindrical bump 102 goes to vertical described ring protection cover body 2, and bottom arc gap edge 204, the distance to annular surface 203 is less than the distance arriving described annular surface 203 bottom described cylindrical bump 102.
When being embodied as; owing to the distance of fixed block 201 both sides is not more than the distance of breach 101 both sides; so first the breach 101 of upper cover 1 edge to be stretched into the fixed block 201 of ring protection cover body 2 edge; cylindrical bump 102 on breach 101 is positioned at arc gap, is pressed in arc gap 202 by cylindrical bump 102.Owing to the diameter of arc gap 202 is not less than the diameter of described cylindrical bump 102, so upper cover 1 can overturn around cylindrical bump 102, it is achieved the opening and closing of Water meter protective cover.As shown in Figure 4; when upper cover 1 goes to be perpendicular to ring protection cover body 2 around cylindrical bump 102; when the edge of upper cover 1 is close to the annular surface 203 of ring protection cover body 2; arc gap edge 204 is less than cylindrical bump 102 top distance to annular surface 203 to the distance of annular surface 203; so upper cover 1 will not come off easily from ring protection cover body 2; realize the connection of upper cover 1 and ring protection cover body 2, when user needs water-meter reading registration, open upper cover 1；After water-meter reading registration, cover upper cover 1.When upper cover 1 damages, being not required to can self-changeable upper cover 1 by instrument.
Compared to traditional mode using pin to fix connection, the new water meter protective cover that the present embodiment provides is simpler when assembling, and can save manpower.In use, it is also possible to avoid the pin caused owing to repeatedly stirring for a long time upper cover to come off the problem causing using.
Fig. 5 is arc gap embodiment one schematic diagram in Fig. 3, as shown in Figure 5, preferably, described arc gap 202 is made up of the first arc surface 205 and plane 206, described plane 206 is tangent with described first arc surface 205, the center of circle of described first arc surface 205 place circle is positioned at inside described arc gap edge 204, and described arc gap 202 edge Opening length is less than the diameter of described cylindrical projection 102.
When being embodied as; owing to the center of circle of the first arc surface 205 place circle on arc gap 202 is positioned at inside arc gap edge 204; arc gap 202 edge Opening length is less than the diameter of cylindrical projection 102; Water meter protective cover all uses plastic material; there is certain elasticity, cylindrical projection 102 can be pressed in arc gap 202, now so needing to add some external force; upper cover 1 can rotate around cylindrical projection 202, and will not come off from ring protection cover body 2.
Fig. 6 is upper cover edge breach schematic diagram in Fig. 3, as shown in Figure 6, it is preferable that described upper cover 1 is along being respectively present the first trapezoidal gradient 103 and the second trapezoidal gradient 104 in the middle part of described breach 101 edge to described upper cover 1 top and bottom.Due to the existence of the first trapezoidal gradient 103, when opening upper cover 1, upper cover 1 top can overturn 180 °, facilitates water-meter reading reading；Due to the existence of the second trapezoidal gradient 104, when covering upper cover 1, bottom upper cover 1, it is adjacent to ring protection cover body 2 completely, it is to avoid dust etc. enter.
Fig. 7 is arc gap preferred embodiment two schematic diagram in Fig. 3, as shown in Figure 7, it is preferable that described arc gap 202 first arc surface 205 is connected with described arc gap edge 204 by the second arc surface 207.When being embodied as, due to the existence of the second arc surface 207, the cylindrical bump 102 on upper cover 1 is easily pressed in arc gap 102, and on fixed block 201, the first arc surface 205 is hardly damaged with junction, arc gap edge 204, increases the service life.
Fig. 8 is annular protective enclosure outer schematic diagram in Fig. 3, and as shown in Figure 8, described ring protection cover body 2 is provided with annular outer 208, with the assembling of hydrous water watch case.When being embodied as; ring protection cover body 2 arranges annular outer 208; when water meter assembles; as it is shown in figure 9, annular outer 208 is pressed on water gage glass sheet 210 by watermeter shell 209, it is not necessary to arrange bolt fitting holes on Water meter protective cover; buckle and snap ring etc.; simplify the manufacturing process of Water meter protective cover, save Water meter protective cover material, and convenient for assembly.
Using the new water meter protective cover that this utility model provides, water meter upper cover is easily disassembled with ring protection cover body, is hardly damaged, and service life is long；Easily assembling.
Although the most more employs such as upper cover, ring protection cover body, breach, arc gap, cylindrical bump, the term such as fixed block, but is not precluded from using the probability of other term.Use these terms to be only used to more easily to describe and explain the essence of the present invention；It is all contrary with spirit of the present invention for being construed as any additional restriction.
Finally it should be noted that various embodiments above, only in order to the technical solution of the utility model to be described, is not intended to limit；Although this utility model being described in detail with reference to foregoing embodiments, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or the most some or all of technical characteristic is carried out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of this utility model each embodiment technical scheme.
