Description

Tensimeter sampling anti-theft lock device

Technical field: the utility model relates to the locking device field, is specially a kind of tensimeter sampling anti-theft lock device.

Background technology: at present, on China's tensimeter, also do not have anti-theft device.

Summary of the invention: the purpose of this utility model is to provide a kind of simple in structure, with low cost, safe and reliable, survivable, the anti-theft lock device of tensimeter sampling easily of taking a sample.

The purpose of this utility model is achieved in that it comprises O type circle (1), O type circle (2), lock core (3), lock body (4), O type circle (5), lock slots (6), pellet shot from a slingshot (7), pod apertures (8), pod apertures (9), lock core space (10), lock core hole (11), lock body space (12), jump ring (13).Lock core (3) is in the below off-centre of lock body (4), lock core (3) is slidingly matched in lock body (4), pellet shot from a slingshot (7) slides in the pellet shot from a slingshot hole of lock body (4) and lock core (3), O type circle (2) is embedded in the lock core (3), O type circle (1) is embedded in the lock body (4), O type circle (5) is embedded in the lock body (4), and card yellow (13) is pushed down lock core (3) and is embedded in the lock body (4), and lock core (3) is fixed on the lock body 4.The utility model has the advantages that: simple in structure, with low cost, safe and reliable, sampling, pressure are convenient, fast, rotate light.

Description of drawings: Fig. 1 looks synoptic diagram for the utility model structural principle section master; Fig. 2 is the utility model structural principle schematic side view.

Embodiment: it comprises O type circle (1), O type circle (2), lock core (3), lock body (4), O type circle (5), lock slots (6), pellet shot from a slingshot (7), pod apertures (8), pod apertures (9), lock core space (10), lock core hole (11), lock body space (12), jump ring (13).Lock core (3) is in the below off-centre of lock body (4), lock core (3) is slidingly matched in lock body (4), pellet shot from a slingshot (7) slides in the pellet shot from a slingshot hole of lock body (4) and lock core (3), O type circle (2) is embedded in the lock core (3), O type circle (1) is embedded in the lock body (4), O type circle (5) is embedded in the lock body (4), and card yellow (13) is pushed down lock core (3) and is embedded in the lock body (4), and lock core (3) is fixed on the lock body 4.The utility model course of work: this lock body is fixed on body or the valve body, can take a sample at any time or monitor hydrodynamic pressure, after key inserted the lock core space, pellet shot from a slingshot moves on up and down in its hole, play the slip rotation relationship between locked or unlatching lock core and the lock body, the utility model sampling key drives lock hole and plays circular motion between rotary locking cylinder and the lock body, makes liquid not pass through pod apertures (8) and pod apertures (9) enters in the key pressure samples device.Revolve turn 90 degrees after, liquid is from entering the key pod apertures to pod apertures through pod apertures, then to tensimeter or sample valve, turns over and turn 90 degrees and can close, taking out key can be antitheft.
