Specific embodiment
Specific embodiment of the present utility model is used to illustrate the utility model, but is not limited to the specific implementation
Mode.
Below by taking the transmission equipment in express delivery Automated Sorting System as an example, the utility model is specifically described.
Fig. 1 is the stereoscopic schematic diagram of the transmission equipment for being equipped with seal of the utility model embodiment.
As shown in Figure 1, being equipped with seal 2 on the transmission equipment 1 of the present embodiment, electronics is installed on seal 2
Element 3.
Fig. 2 is I enlarged drawing in Fig. 1.
As shown in Fig. 2, the seal 2 of the present embodiment, is mounted on the main frame 11 of transmission equipment 1, including bracket
22 and insulation spacer 21, bracket 22 is used for supporting electronic components 3, and insulation spacer 21 is arranged between bracket 22 and transmission equipment 1,
And bracket 22 and insulation spacer 21 are fixed on transmission equipment 1 by insulated connecting piece 24.
Bracket 22 includes pedestal 221, connecting column 222 and support plate 223, and pedestal 221 is mounted on 21 top of insulation spacer, and
It is fixed on transmission equipment 1 by insulated connecting piece 24,222 one end of connecting column is fixed on pedestal 221, the other end and support plate
223 are fixedly connected, and electronic component 3 is equipped in support plate 223.
In the present embodiment, electronic component 3 is the coded system that encoder 31 and 32 component of code wheel form, the coded system
It is a kind of rotating detector that swing offset is converted into string number pulse signal, these pulses can be used to pilot angle position
It moves, if encoder is combined together with gear bar or screw, it can also be used to measure straight-line displacement.
Encoder 31 and code wheel 32 are separately mounted to the two sides of support plate 223, and code wheel 32 is bolted on branch
On fagging 223.
In order to guarantee to be isolated as far as possible electrostatic and potential difference, the size of support plate 223 should be designed to make electronic component 3 with
