Abstract
The utility model relates to a bolt lock preventing prizing and stealing, which solves the technique problem of that: the bolt movement end is completely shielded, and cooperated closely with the lower part, reducing the prizing space. The bolt lock afforded by the utility model is characterized in that: the utility model is provided with a spherical crown shaped barrel body (1) with a nut cavity (1-1) at the bottom, and the nut cavity is provided with a through hole, and a pin hole (1-2) is positioned on the inside wall of the through hole. A rotary lock shell (2) is positioned in the through hole, and the upper surface of the lock shell is provided with a rotating mechanism, and the lower end is provided with an inner threaded sleeve (6). A lock core (3) with a poke rod (4), and an oval poke disk (5) is fixedly positioned on the poke rod, and a spring pin mechanism (7) installed in the lock body is touched with the poke disk.
Description
Technical field
The utility model relates to a kind of lockset, specifically is that a kind of bolt of prizing and stealing that prevents is locked.
Background technique
Chinese patent literature CN2069363U discloses " a kind of motor vehicle Security for fuel tank bolt lock ", and it is made up of the bolt of band groove and the protecting cover of band hole clipping.Protecting cover can encase nut, is not prized and groove-hole clipping structure can guarantee that protecting cover can only dally.But it is special that the bolt of this structure needs, and its intensity reduces because of the protecting cover structure, and particularly nut and protecting cover prize to have stayed to brute force and put forth effort the space solitarily on bolt.
Summary of the invention
The utility model technical issues that need to address are, the whole bag of bolt movable end is protected, and cooperate closely with the bottom, dwindle prizing the space.
Bolt lock of the present utility model is characterized in that having a spherical crown shape cylindrical shell, and nut cavity is arranged at the cylindrical shell bottom, and nut cavity is provided with through hole, and through-hole wall has pin-and-hole; Be provided with rotating lock housing in the through hole, the lock housing upper surface is stirred structure, swivel nut in the band of lock housing lower end; The lock core of band turning lever is arranged in the lock housing, be connected with oval plectrum on the turning lever, be provided with spring pin mechanism in the lock body and contact with plectrum.Lockset is designed to the spherical crown shape can allow instruments such as spanner lose force surface; Having designed nut cavity can dwindle and prize the space; Swivel nut entangles bolt to be locked in the design, can stop lockset to be pulled by external force, thereby has realized anti-prizing and stealing more dexterously.
As preferably, the rotational structure of lock housing upper surface can be pit or projection.As two and above pitting, or projection.As long as can effortlessly it be turned with simple tools such as climbing nail or first quarter moon spanner.
Structural integrity of the present utility model is good, makes general tool lose force application part, thereby has prevented from dexterously to prize and steal.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described further.
Embodiment 1.See Fig. 1, this routine bolt lock is combined by lock housing-two of Nei swivel nuts of a spherical crown shape cylindrical shell 1 and the cylindrical shell of can packing into.Six-sided nut chamber 1-1 is arranged at spherical crown shape cylindrical shell 1 bottom, and nut cavity is provided with through hole, and through-hole wall has a pair of pin-and-hole 1-2.Be provided with rotating lock housing 2 in the through hole, the lock housing lower end is the interior swivel nut 6 conjuncted with it, and the lock housing upper surface has a pair of pitting 10; Lock core 3 is arranged in the lock housing, and lock core is divided into turning lever 4, is welded with oval plectrum 5 on the turning lever, is provided with spring pin mechanism 7 in the lock housing and contacts with plectrum 5.
Fixed structure with stepney is an example.During use, earlier the nut cavity 1-1 of this lockset is enclosed within on the hexagon nut 8 on the spare tyre pressing plate 11, and is close to pressing plate as far as possible.Insert key and turn core 3-turning lever 4 for clockwise 90 °, allow plectrum 5 be in oval-shaped minor axis, pin 7 contracts under the effect of spring.Push down pitting 10 rotations with climbing nail again, lock housing-Nei swivel nut is rotated, put some the button at bolt 9 heads that pass pressing plate 11.Confirming that swivel nut 6 is inserted in the degree of depth when enough, take away and climb nail, instead twist key promote pin always by plectrum 5; When arriving pin-and-hole 1-2 position, the elastic force that pin promptly overcomes spring ejects (see figure 2), core is lived surely, as long as it is promptly locked to extract key nut.Because the hexagon nut 8 on the pressing plate 11 is entangled by nut cavity 1-1, can guarantee that nut 8 does not directly contact and is disassembled with instrument; Because the lockset outward appearance becomes spherical crown, can guarantee that cylindrical shell can not dismantled by spanner class instrument yet; Because interior swivel nut 6 has been inserted in bolt 9 and has been close to pressing plate, can guarantee that the bolt lock can not be pulled.So bolt lock of the present utility model is not easy to be turned by improper.
Claims (2)
1, a kind of bolt lock is characterized in that having a spherical crown shape cylindrical shell (1), and nut cavity (1-1) is arranged at the cylindrical shell bottom, and nut cavity is provided with through hole, and through-hole wall has pin-and-hole (1-2); Be provided with rotating lock housing (2) in the through hole, the lock housing upper surface has rotational structure (10), swivel nut (6) in the band of lock housing lower end; The lock core (3) of band turning lever (4) is arranged in the lock housing, be connected with oval plectrum (5) on the turning lever, be provided with spring pin mechanism (7) in the lock body and contact with plectrum.
2, bolt lock according to claim 1 is characterized in that the structure (10) of stirring of described lock housing upper surface can be pit or projection.
