Description
Technical field
The utility model relates to a kind of anti-thefting facility, more specifically is a kind of manhole antitheft lock device at the underground passage well lid.
Background technology
Present existing underground passage well cover antitheft device, because structure design is reasonable inadequately, anti-theft effect is bad, often by some persons of being greedy for small gains, pry open the back stealing with general general tool such as drill rod etc. and sell off, make well head exposed, often cause some personal security incidents, someone disables even loss of life, causes great harm for people's life security; Existing manhole antitheft lock simultaneously, when needs are normally opened well lid the inconvenient operation because keyhole is usually blocked, and since the connecting rod of pattern manhole cover lock easily blocked by dirt etc., when the opening and closing pattern manhole cover lock, waste time and energy and operating efficiency poor.
Summary of the invention
The utility model purpose provides a kind of above-mentioned shortcoming that can overcome, and has that theftproof is strong, pollution discharge capability good, open or close a kind of simply and easily manhole antitheft lock device.
The utility model is realized in the following way: a kind of manhole antitheft lock device, to form by key, tapered end, connecting rod, and the key bit of key and key rod are movable the bindings; A safety block is arranged in the tapered end and leave the embedded spring hole of installing with the corresponding snap of different key bits; Connecting rod is to be become with rotating shaft pin connection rod set by the pin connecting rod that shaft machine connects.
Leave and close the corresponding hole of tooth on the key rod of key.Close tooth by riveting with the unlatching tooth behind the key rod.
Shaft machine is fixed on the well lid by central rotating shaft, and two spacing holes are arranged on the shaft machine.Spacing hole is controlled two connecting rods respectively, further controls the open and close of anti-theft device.
Admittedly sell for two of close well and leave on the device and the corresponding hole of pin; Leave on all the other fixators and the corresponding hole of connecting rod.Admittedly sell device broad, thick for two, can strengthen anti-destruction, pick-proof ability.
Lockhole is corresponding with the hole on the well lid when mounted.Also can open some holes on the lock housing, to strengthen the pollution discharge capability of lock more.
The beneficial effects of the utility model are: 1, theftproof performance is strong.After adopting this lock of the built-in installation of well lid, do not change the original appearance of well lid, can not move, be difficult for prizing, have good anti-theft effect.2, blowdown, anti-foreign material performance are good.3, open or close simple and convenient.4, use is wide.

Specific embodiment
As shown in Figure 1, a kind of manhole antitheft lock device is made up of key, tapered end, connecting rod, and connecting rod is divided into pin connecting rod (6) and rotating shaft pin connecting rod (16) two parts, and they are fixed on the well lid (18) by fixator (19).Connecting rod is pin (4) away from the thick part in two ends of shaft machine (17), and pin (4) is fixed on the well lid (18) by selling device (5) admittedly, and the overall length of connecting rod should and place on the well (20) greater than well lid.Connecting rod leans on into, and two end points of shaft machine (17) insert respectively in the spacing hole (15) of shaft machine (17).Shaft machine (17) is fixed on the well lid (18) by central rotating shaft (14); There are corresponding two spacing holes (15) both sides of central rotating shaft.Two and the corresponding spacing hole of banking pin (12) are arranged on the pin connecting rod (6), and pin connecting rod (6) inserts in the spacing hole (15) by cotter way (13) back of theftproof lock.Theftproof lock is fixed on the well lid by three screws (10).When whole anti-theft device is installed as for below the well lid (18).
Be lock head separation structure schematic diagram as shown in Figure 2, there are three screws (10) to be used for tapered end is fixed on the well lid (18) on the lock housing (1), it is the rotation path of key key bit that the groove (2) of depression is arranged in the lock housing (1), groove (2) is divided into inside and outside two-layer lock housing to lock housing (1), lock housing (1) centre is the lockhole (3) of hollow, lock housing (1) goes up and is fixed with a safety block (7) by screw, can stop that approximate key passes through, on the inner and outer shell between group plate (8) on safety block (7) and the pin connecting rod (6), a pair of embedded spring hole (9) is arranged.The shape of embedded spring is corresponding with the shape of key key bit in the embedded spring hole (9), also be provided with two corresponding spacing holes that two banking pins (12) pass the pin connecting rod respectively on the tapered end, can make between pin connecting rod (6) and the cotter way (13) and leave the space, improve blowdown, anti-foreign material.Can get through a plurality of holes on the lock housing, to improve blowdown, anti-foreign material.
As shown in Figure 3, the key bit of key and key rod are movable the bindings, leave and close the corresponding hole of tooth (23) on the key rod (21), close after tooth (23) passes key rod (21), carry out riveted and fixed by rivet hole (24), convertible so different key key bits with unlatching tooth (22) again.
Shaft machine (17) is fixed on the well lid (18) by central rotating shaft (14), has two spacing holes (15) can allow connecting rod move interior on the shaft machine.Spacing hole is controlled two connecting rods respectively, further controls the open and close of anti-theft device.
As shown in Figure 4, leave on the device (5) and the corresponding hole of pin (4) selling admittedly near two of well; Leave on all the other fixators (19) and the corresponding hole of connecting rod.
When mounted, lockhole (3) is corresponding with the hole on the well lid.
