一种电能表锁扣式封印 技术领域  Electric energy meter lock type seal technology
本发明属于封印技术领域， 特别涉及一种电能表锁扣式封印。 背景技术  The invention belongs to the field of sealing technology, and particularly relates to a power meter lock type seal. Background technique
电能表封印是一种防止未授权人打开电能表的装置， 其能够防止未授权人变动电能表结 构或者设置进行窃电。 目前， 在电力行业内， 传统封印结构是采用封印线穿过塑料外壳， 封 印螺钉， 再把两头塞到一个封印结构件里， 采用按压或者旋转的方式固定封印线， 在不破坏 封印结构件和拉断封印线的前提下不能拉出封印线， 从而不能旋转封印螺钉， 使非授权人不 能拧开封印螺钉， 打开被封印结构， 起到加封、 防破坏和防窃电的作用。 此结构主要存在以 下四方面的不足： 其一， 传统封印需穿封印线， 安装步骤比较繁琐， 加封效率较低； 其二， 传统封印结构的防盗性能差； 其三， 传统封印采用的铅， 对环境污染严重， 并且安装工作人 员长期接触铅， 易引起中毒； 其四， 传统封印不利于数字化管理和高效自动加封的需要。  The energy meter seal is a device that prevents an unauthorized person from opening the energy meter, which prevents an unauthorized person from changing the power meter structure or setting up to steal electricity. At present, in the power industry, the traditional seal structure uses a seal line through a plastic casing, seals the screw, and then plugs the two ends into a seal structure, and fixes the seal line by pressing or rotating, without damaging the seal structure and Under the premise of breaking the seal line, the seal line cannot be pulled out, so that the seal screw cannot be rotated, so that the unauthorized person can not unscrew the seal screw and open the sealed structure to seal, prevent damage and prevent electric theft. This structure mainly has the following four shortcomings: First, the traditional seal needs to wear the seal line, the installation steps are cumbersome, and the sealing efficiency is low; Second, the traditional seal structure has poor anti-theft performance; Third, the lead used in the traditional seal, The environmental pollution is serious, and the installation workers are exposed to lead for a long time, which is easy to cause poisoning. Fourth, the traditional seal is not conducive to the needs of digital management and efficient automatic sealing.
虽然现有技术对封印结构进行了诸多改进， 有些已经无须穿封印线， 对安装步骤进行了 简化， 但由于结构仍比较复杂， 而且还需要进行封印孔与其它部件间的校正， 所以， 安装操 作繁琐， 无法进行自动加封； 有些封印结构的改进， 则是暂时可以起到防盗作用， 但由于结 构上仍存在缺陷， 所以封印比较容易老化， 经过一段时间， 封印就降低或失去了防盗性能， 所以需要频繁更换， 提高了管理成本， 不利于实施。 发明内容  Although the prior art has made many improvements to the seal structure, some have no need to wear a seal line, which simplifies the installation procedure, but since the structure is still complicated, and correction between the seal hole and other components is required, the installation operation is performed. It is cumbersome and cannot be automatically sealed; some seal structure improvements can temporarily prevent theft, but because the structure still has defects, the seal is more susceptible to aging. After a period of time, the seal reduces or loses the anti-theft performance, so Frequent replacement is required, which increases management costs and is not conducive to implementation. Summary of the invention
为了克服现有技术的上述缺陷， 本发明的目的在于提出一种防盗性能好， 便于安装且能 够满足自动加封需求的电能表锁扣式封印。  In order to overcome the above-mentioned drawbacks of the prior art, it is an object of the present invention to provide an electric energy meter lock-type seal which is excellent in anti-theft performance, is easy to install, and can meet the requirements of automatic sealing.
本发明是通过如下技术方案实现的：  The invention is achieved by the following technical solutions:
一种电能表锁扣式封印， 包括底座和封印盖， 所述底座内设有沉孔， 通过该沉孔穿设用 于固接电能表壳体的螺钉， 所述封印盖位于螺钉上方， 其特征在于： 所述封印盖的下部伸入 底座的沉孔中， 所述封印盖的下端外周面上设有向外延伸的凸台， 沿底座的内壁周向设置有 弹性凸起， 所述弹性凸起的下端部向底座内倾斜、 且向下延伸并抵靠于封印盖的凸台上。  An electric energy meter lock type seal, comprising a base and a seal cover, wherein the base is provided with a counterbore through which a screw for fixing the electric energy meter case is disposed, the seal cover is located above the screw, The lower part of the sealing cover protrudes into the counterbore of the base, and the outer peripheral surface of the lower end of the sealing cover is provided with an outwardly extending boss, and an elastic protrusion is arranged along the inner wall of the base, the elasticity The lower end of the projection slopes into the base and extends downwardly against the boss of the closure.

When the base is subjected to external violence, it will not be damaged, and the seal can provide good support strength. The seal structure adopts the above elastic protrusion to cooperate with the boss The form realizes the fastening of the base and the sealing cover, so the sealing cover cannot be taken out from the base without damaging the sealing structure. The elastic protrusion and the boss adopt a matching structure of "the lower end portion is inclined toward the inside of the base and extends downward and abuts against the boss of the sealing cover", and the elastic protrusion of the structure does not need to be in a pressed state all the time. Therefore, the aging of the elastic protrusion is effectively delayed, the anti-counterfeiting and the anti-theft property are stronger, and the service life of the seal is prolonged; in addition, the overall structure of the seal is simple, and the alignment of each seal hole is not required before installation, and the installation can be directly performed. Easy to install and operate, it is suitable for automatic sealing of the assembly line, which greatly reduces the work intensity, reduces the cost and increases the output.
较优地， 所述封印盖包括盖板和上、 下开口的柱状套， 所述柱状套的上端外周面上设有 外凸沿、 其下端外周面上设有向外延伸的凸台； 所述盖板设置于柱状套的上端， 所述盖板的 下板面开设有第一易损槽。  Preferably, the seal cover comprises a cover plate and upper and lower open cylindrical sleeves, wherein the outer peripheral surface of the upper end of the cylindrical sleeve is provided with an outer convex edge, and the outer peripheral surface of the lower end is provided with an outwardly extending boss; The cover plate is disposed at an upper end of the column sleeve, and the lower plate surface of the cover plate is provided with a first vulnerable groove.
在盖板上设置第一易损槽的结构， 由于第一易损槽的强度较弱， 所以若需要进行维修时， 可通过破坏第一易损槽而开启盖板， 便于维修。  The structure of the first vulnerable groove is arranged on the cover plate. Since the strength of the first vulnerable groove is weak, if the maintenance is required, the cover plate can be opened by breaking the first vulnerable groove, which is convenient for maintenance.
