The utility model discloses a pry-proof water meter with a protective cover, which comprises a shell, a reading window, an inlet end and an outlet end. A metal pry-proof protective cover is arranged at the reading window; a vertical square hole is arranged on the side wall of the pry-proof protective cover, and a matching vertical pole and a vertical master pole are arranged in the vertical square hole; the cross section of the vertical pole is convex; The cross section of the vertical master bar is concave-shaped; the vertical master bar is provided with a bump on the side wall opposite its concave surface; the anti-prying protective cover is provided with a transverse through hole on the side wall adjacent to the reading window; the transverse through hole extends to the side wall of the reading window to form an inner concave part; and the convex block cooperates with the inner concave part. Since the anti-prying protective cover is not welded and fixed with the water meter shell, it is fixed with the reading window by the cooperation of the vertical rod, the vertical master rod and the concave part. The anti-prying protective cover has the function of anti-prying and can be disassembled, and has simple structure and convenient use.

保护罩防撬式水表
本技术涉及供水设备领域,尤其涉及一种保护罩防撬式水表。
技术介绍
现有水表在读表窗口处通常设有盖板或保护罩,防止灰尘进入读表窗口内或人为破坏读表窗口从而拆卸水表;而现有的保护罩很多不具有防撬功能,部分具有防撬功能的保护罩也会存在结构复杂,安装成本高,防撬效果差的缺陷。
技术实现思路
本技术的目的就是要克服现有的水表保护罩不防撬的问题,提供一种防撬效果好,结构简单,安装方便的保护罩防撬式水表。为实现上述目的,本技术所设计的保护罩防撬式水表,包括壳体、读表窗口、进水端和出水端,所述读表窗口处罩设有金属防撬保护罩;所述防撬保护罩为底端敞口的圆形罩体,其侧壁设有竖直方孔,其上端嵌设有钢化玻璃层;所述竖直方孔内设有相配合的竖直公杆和竖直母杆;所述竖直公杆的横截面为凸字形;所述竖直母杆的横截面为凹字形;所述竖直母杆在与其凹面相对的侧壁上设有凸起块;所述防撬保护罩在与读表窗口相贴的侧壁设有横向通孔;所述横向通孔延伸至所述读表窗口的侧壁形成内凹部;所述凸起块与所述内凹部配合;所述竖直公杆与所述竖直母杆相配合后两者外壁与所述竖直方孔的内壁间隙小于3mm;所述竖直母杆与所述凸起块的厚度之和a等于所述竖直公杆和竖直母杆的厚度之和b;所述竖直公杆的上端固定有公杆拉手;所述竖直母杆的上端固定有母杆拉手。进一步,所述公杆拉手边缘设有末端朝下弯曲的延伸部,所述延伸部贴壁扣合于所述防撬保护罩上端边缘处。进一步,所述母杆拉手为朝背对所述公杆拉手的方向水平延伸的横向板体,其末端与所述防撬保护罩上端之间具有3~6mm的间隙。通过将母杆拉手末端与防撬保护罩上端之间设置间隙,便于拉出竖直 ...
