Cap, bearing, counter, backing pin, snap-gauge pin, counter transmitter gear, counter lock pin, it is characterised in that：The backing pin
Seat a and pin socket b is separately fixed on main board a and main board b with engagement thread, and backing pin floats and is through pin socket a and backing pin
The centre of seat b, the counter are installed in the open slot of main board a lower parts, counter transmitter gear and driving gear
After ratcheting, counter lock pin automatic clamping positions on the notch of main board a.
The beneficial effects of the utility model：The utility model proposes a kind of well mouth of oil well with wireless depth count lower sheave
Device, solves the problems, such as that definite transmission operation is time-consuming and laborious, the signal that count receiver is spread out of with wireless receiving transmitter is real
Now count, prevented the appearance of bad, short-circuit, breaking, damaged etc. the failure of cable insulation；Realize reliable operation, it is quick for installation,
The problems such as easy to maintain.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figs. 1-2, a kind of well mouth of oil well of the utility model counts lower sheave device, including fixation with wireless depth
Snap-gauge 1, main board a201, main board b202, open slot 203, axis pin 3, limit shaft 4, pin socket a5, pin socket b6, pulley 7,
Head bolts 8, oiling nozzle 9, end cap 10, gear fixing screws 11, square key 12, driving gear 13, terminal block ring 14, stop collar 15,
Main shaft 16, shaft nut 17, bearing 18, counter 19, backing pin 20, snap-gauge pin 21, counter transmitter gear 22, counter lock
Pin 23 forms；Main board is made of main board a201 and main board b202, and main board is made of carbon steel, main board a201, main body
Plate b202 is connected by main shaft 16, axis pin 3, limit shaft 4；Pin socket a5 and pin socket b6 are separately fixed at main body with engagement thread
On plate a201 and main board b202, backing pin 20, which floats, is through the centre of pin socket a5 and pin socket b6, and oiling nozzle 9 is installed on end cap
On 10, end cap 10, bearing 18, stop collar 15, terminal block ring 14 form a lubricating grease circulation passage, and head bolts 8 are end cap 10
It is fixed on pulley 7, square key 12 plays main shaft 16 and main board between main shaft 16 and main board a201, main board b202
The effect that a201, main board b202 are mutually rotated, main shaft 16 are fixed on main board a201 and main board by shaft nut 17
