Embodiment 1

[0023] Such as figure 1 , figure 2 As shown, the elastic locking metering and sealing device of the present invention includes a meter housing 3 with a mounting hole 31, a sealing screw 2 placed in the mounting hole 31 of the meter housing 3, and a sealing screw 2 placed in the mounting hole 31. The plastic seal 1 on the top of the plastic seal 1 has a plastic cover 11 and a plastic card seat 12 that is engaged with the seal screw 2. The plastic card seat 12 is integrally provided with at least one hook 1211. The elastic locking block 121 , the inner surface of the hook portion of the hook 1211 is a plane, and the top of the sealing screw 2 is correspondingly provided with a locking groove 21 matching with the hook on the plastic card holder 12 . An electronic seal label or an anti-counterfeit label is provided between the plastic seal cover 11 and the bottom of the plastic card holder 12 in the meter housing 3 .

[0024] Such as figure 2 As shown, there are three elastic...

Embodiment 2

[0031] This embodiment is basically the same as the first embodiment, except that: the inner surface of the hook portion of the hook 1211 is an upwardly inclined slope.

Abstract

The invention belongs to the technical field of meter-sealing products and particularly discloses an elastic locking type meter-sealing device. The elastic locking type meter-sealing device comprises a meter shell with an installing hole, a sealing screw arranged in the installing hole of the meter shell and a plastic seal arranged on the sealing screw. The upper portion of the plastic seal is provided with a plastic cover body and a plastic clamping seat which is connected with the sealing screw in a matched and clamped mode. At least one elastic clamping block with a clamping hook is integrally designed on the plastic clamping seat. The top of the sealing screw is correspondingly provided with clamping grooves matched with the claming hooks on the plastic claming seat. The elastic locking type meter-sealing device effectively prevents some lawless persons from opening a cover of a meter arbitrarily, has good anti-opening and anti-theft performance, and is simple in structure and sealing process, convenient and fast to use, firm in structure, and capable of reducing pollution and damage to the environment and a human body.

Description

technical field [0001] The invention relates to a sealing device, in particular to an elastic locking metering and sealing device. Background technique [0002] The meter seal is a device to prevent unauthorized opening of the meter cover, which can prevent unauthorized changes to the meter structure or settings. In the prior art, in the field of sealing technology for metering devices such as water, electricity, oil, and gas, there are usually lead seals and seals with sealing lines. , The installation efficiency is low, and it is not convenient to popularize and apply under the situation that the metering devices such as electrical appliances are used more and more today. [0003] In order to overcome the deficiencies in the existing technologies, some inventors have improved the existing technologies. For example, Chinese Patent Publication No. CN202204855U, published on April 25, 2012, is an invention of an anti-theft seal structure for an electric energy meter. The el...
