Embodiment Construction
[0025] Such as figure 1 , figure 2 , image 3 As shown, a combined metering seal according to the present invention includes a housing 1, an outer insert 2 and an inner clamp 3, and the outer insert 2 and the inner clamp 3 are snapped together inside the housing 1 and sealed in the housing 1 Inside, the shell 1, the outer insert 2 and the inner clip 3 are correspondingly provided with threading holes or threading slots for the sealing line to pass through, specifically the two threading holes 11 on the shell 1 and the threading holes of the outer insert 2 25, and the threading hole 323 and the pre-threading hole 324 of the inner clip 3.
[0026] Depend on figure 1 , figure 2 It can be seen that the shell 1 is open at both ends, including an open end A and an open end B, and the inner clip 3 includes a terminal 31 placed at the inner end of the open end A of the shell 1 and a card placed inside the shell 1. The core 32 , two card springs 321 are symmetrically arranged on...

The invention belongs to the technical field of locking and sealing of metering devices, and particularly discloses a combination metering seal which comprises a casing (1), an outer inserting piece (2) and an inner clamping piece (3). The outer inserting piece (2) is clamped with the casing (1) in matching mode, is clamped with the inner clamping piece (3) inside the casing (1) in matching mode, and is blocked inside the casing (1). The casing (1), the outer inserting piece (2) and the inner clamping piece (3) are correspondingly provided with thread holes or thread grooves for sealing lines to penetrate through. The combination metering seal product is fewer in composition parts and simple, convenient and fast to assemble, and production efficiency is greatly improved. Preassembling of different levels can be achieved simultaneously, the combination metering seal is stable and firm after assembly, anti-opening performance is effectively improved, and the combination metering seal is safe and reliable to use.
Description
technical field [0001] The invention belongs to the technical field of sealing of metering products, in particular to a combined metering seal. Background technique [0002] In the prior art, in the technical field of sealing of water, electricity, gas, oil and other metering devices, taking electrical metering devices as an example, there are usually two sealing methods, specifically the lead seal method and the self-sealing method with sealing wires. Lock-type metering and sealing method. [0003] At present, the self-locking molded case seal with a sealing line includes a sealing line and an engaging device that cooperates with the sealing line. Embedded with stainless steel spring sheets, the shell and cover plate need to be ultrasonically welded, the product consists of many parts, the assembly process is cumbersome, and the assembly efficiency is low; in addition, its sealing performance is not good, the safety performance is poor, and it does not have good anti-openi...
