Four core shielding lines having assemble plug connection, during collection only need to by plug be inserted to correspondence jack i.e. be capable of achieving data transmission and
Collection, has saved test period, improves operating efficiency.
In order to realize above-mentioned task, the utility model uses following technical scheme：
A kind of type vibration wire surface strain meter with detachable base, including the first fixing end and the second fixing end, it is described
The bottom of the first fixing end and the second fixing end is detachably provided with base respectively, and the base is made up of bolt and nut,
The nut bottom is quincunx, and the nut bottom is provided with several annular dimpled grains.
Further, strain protection pipe, the strain protection pipe are provided between first fixing end and the second fixing end
Middle part be provided with data transmission device, the data transmission device is connected by a single data transmission line with data transmission joint,
The data transmission joint is connected with vasculum.
Further, the data transmission joint includes intercalation part and jack portion, the intercalation part by the first plug handle and
Plug is constituted, and the jack portion is made up of the second plug handle and jack.
Further, being marked on the first plug handle and the second plug handle has " 1~4 ".
Compared with prior art, the utility model has following technique effect：
1. the utility model devises dismountable surface strain meter base, can effectively solve type vibration wire surface strain meter
In actual applications, glue location for paste is difficult to clean, strain gauge is unable to the problem of sustainable utilization, it is to avoid waste of material, saves significantly
About experimentation cost, the set design of data transmission joint, has saved test period, and for engineers and technicians' execute-in-place is provided
Convenience；
2. the utility model improves the acquisition mode that existing " four wire terminals folder " is connected respectively, by four cores in transmission line
Shielding line enters row set, is designed as the plug-type joint being easily attached, and during data acquisition, directly draws plug and vasculum
Patch jack correspondence is connected, and greatlys save test period, improves test efficiency.

Specific embodiment
Embodiment 1
As shown in figure 1, a kind of type vibration wire surface strain meter with detachable base, including strain protection pipe 3, strain guarantor
The left end of pillar 3 is tightly connected with the first fixing end 1, built-in rubber pad；The strain right-hand member of protection pipe 3 and the screw thread of the second fixing end 2 connect
Connect；String wire 4 is built in strain protection pipe 3；Data transmission device 5 is arranged on the middle part of strain protection pipe 3, and signal is passed by with data
The data line 9 of the connection of defeated device 5 is transmitted, and data line 9 is connected to connecing for vasculum extraction through data transmission joint 10
The end of a thread, carries out the collection of data.
The data transmission device 5 includes coil 7 and vibration pickup 8, and data are picked up into treatment.
The bottom of the fixing end 2 of first fixing end 1 and second is detachably provided with base 6 respectively.
