Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. It will be understood that, as used herein, the terms "first," "second," and the like may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the present application. The first and second elements are both elements, but they are not the same element.

In this embodiment, as shown in fig. 1-4, the present invention includes: vibration transmitter includes 1 and 1 internally mounted of shell has vibration transmitter body 2, its characterized in that includes: shell 1 includes transmitter casing 3 and gauge outfit casing 4, gauge outfit casing 4 is connected with transmitter casing 3, gauge outfit casing 4 includes upper end cover 42 and tee bend end cover 7, the tee bend end cover includes wiring port 71, electric port 72 and lead terminal 73, and installs circuit board 31 in transmitter casing 3 and be connected with binding post 41, binding post 41 installs on wiring port 71, wiring port 71 is fixed on upper end cover 42. Based on above-mentioned design, technical scheme effectively solved following technical problem: when in maintenance and installation, because the electrical wiring port in the prior art is exposed outside, the volume of the shell occupies a large space, when a user uses the electric wiring port, the electrical wiring port is of a horizontal insertion type structure, the wiring space is limited, and the narrow wiring port space causes certain difficulty in installing a lead wire, thereby bringing great inconvenience to the installation work; moreover, the explosion-proof level in the prior art is lower, the main reason is that the sealing performance is poor, and a garland caused by the damage of an internal circuit can be splashed out of a gap of the shell to cause fire, so that the injury to people and the economic loss are caused.

The central line of the wiring port 71 and the horizontal line form an acute angle along the clockwise direction, so that the wiring terminal 41 installed on the wiring port 71 is obliquely arranged, and the wiring space in the three-way end cover 7 is increased.

Wherein the sealing element 6 comprises a sealing ring 61 and a sealing gasket 62, the sealing ring 61 being arranged between the upper end cap 42 and the connection port 71, the sealing gasket 62 being arranged at the port of the connection port 71 to form a sealing result between the upper end cap 42 and the connection port 71. The sealing ring 61 can be an O-shaped ring, for example, the O-shaped ring is a circular rubber sealing ring, the device utilizes the sealing element 6 to have higher sealing performance, so that the device can be used in industrial places with large dust and extremely harsh environment, and the sealing effect can improve the explosion-proof grade. Spark generated by the circuit board is effectively prevented from being sprayed to the outside of the meter head shell, and then the thickness of the wall of the shell 1 is thickened, the transmitter shell 3 is made of stainless steel, and the meter head shell 4 is made of cast aluminum or stainless steel and used in a high-corrosion environment.

The three-way end cover 7 and the upper end cover 42 are fixedly connected through a jackscrew structure 43. The jackscrew structure 43 can be a jackscrew, and the jackscrew is used for jacking a small screw moving on the shaft, so that the phenomenon that the screw is easy to slip is effectively prevented in a long-term vibration state, and the reinforcing device prevents equipment from being damaged, thereby having a positive effect on an explosion-proof function. The transmitter shell 3 is mechanically connected with the gauge head shell 4 in an ET threaded connection mode; the upper end cover 42 is connected with the three-way end cover 7 through metric screw threads, and has high sealing performance and fastening performance.

The circuit board 31 is fixed in the transmitter housing 3 through an epoxy resin layer, and an electric wire led out from the circuit board 31 is connected with the wiring terminal 41 through the wiring port 73. When the installation is overhauled, upper end cover 42 can be opened, and the electric wire is introduced to binding post 41 of wiring port 71 department through electric port 72 on, can realize being connected of this device and external line, easy to assemble.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present application.
