Abstract
The utility model relates to a novel manhole cover lock and an opener thereof. The main technical characteristics are that: the manhole cover lock is formed by connecting a lock body, a lock core, and a tongue; the lock body is a rectangular plate body with a rectangular groove at the middle and through holes at two ends; the lock core is sleeved in a round hole formed at the center of the rectangular groove; the lock core is a cylinder body of which the diameter of the upper end is larger than that of the lower end; a pair of key slots are formed on an upper-end edge of the cylinder body; and a lower-end edge of the cylinder body is fixed with the rectangular tongue. The novel manhole cover lock with rational design can be mounted on an inner-side surface of various outer covers and can be opened and locked by a specific opener; moreover, the lock has features of strong anti-theft performance, simple structure, low cost, and convenient installation and maintenance and the like.
Description
Technical field
The utility model belongs to the manhole cover field, especially a kind of new pattern manhole cover lock and opener thereof.
Background technology
At present, be embedded in underground transmission line of electricity and be provided with inspection-pit, well lid is installed on inspection-pit.Well lid constitutes by being fixed on well seat on the inspection-pit matrix and the enclosing cover that is installed on the well seat usually, and enclosing cover can be opened and separates fully with the well seat from the well seat.Stolen in order to prevent manhole cover, normally install weld tabs additional or measure such as trip bolt is installed between loam cake and base at place, the dislodging hole of loam cake, still, the form that installs weld tabs additional can be easy to be destroyed by instruments such as crowbars, is difficult to play antitheft effect; Adopt the form of trip bolt, also used common tool such as monkey wrench to open easily by other people, still do not have good antitheft effect.Now, though the mount pin locking device is also arranged between loam cake and base improving theftproof performance,, these lock apparatus structure complexity, easily damage and also cost higher, therefore also be difficult to promote the use of.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, with low cost and new pattern manhole cover lock and opener thereof that theftproof performance is strong are provided.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of new pattern manhole cover lock, connect and compose by lock body, lock core and dead bolt, lock body is that a middle part is provided with the rectangle plate body that rectangular recess and two ends are shaped on through hole, in the circular hole that rectangular recess central authorities are shaped on, be set with lock core, this lock core is the cylinder cylindrical shell of a upper end diameter greater than lower end diameter, be shaped on a pair of key on the upper end of cylinder cylindrical shell tube edge, the lower end tube of cylinder cylindrical shell is along being solidly installed with the rectangle dead bolt.
And a limited block is installed in the outer end of the upper and lower side junction of described cylinder cylindrical shell, and this limited block is inlaid in the 90 degree stopper slots that lock is shaped on.
And described lock body, lock core and dead bolt are stainless steel material.
And the lower end of described dead bolt and cylinder cylindrical shell adopts welding manner to be solidly installed.
A kind of opener of pattern manhole cover lock is connected and composed by handle and column, and handle installs an end of column, and the projection with the key coupling radially is installed in the other end both sides of column.
Advantage of the present utility model and good effect are:
1, the employing of this pattern manhole cover lock is sleeved on lock core on the lock body and with dead bolt and is solidly installed, and by unlatching and locking function that the key and the special-purpose opener of lock core upper end can be realized pattern manhole cover lock, it is simple and practical, and is with low cost.
2, this pattern manhole cover lock can be installed together by the bolt mode with the enclosing cover of any kind, and its scope of application is extensive, and installation and easy to maintenance can solve the stolen problem of well lid effectively.
3, the utility model is reasonable in design, it can be installed on the inner surface of various enclosing covers and realize the unlatching and the locking function of pattern manhole cover lock by the special opening instrument, and it is strong, simple in structure, with low cost and be convenient to characteristics such as I﹠M to have a theftproof performance.
Description of drawings
Fig. 1 is the structural representation of pattern manhole cover lock;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Fig. 3 is the structural representation of pattern manhole cover lock opener.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described:
A kind of new pattern manhole cover lock as shown in Figure 1 to Figure 3, is connected and composed by lock body 1, lock core 3 and dead bolt 5, and lock body, lock core and dead bolt all adopt stainless steel material to make.Lock body is the corrosion resistant plate that a middle part is provided with rectangular recess 10, is shaped on through hole 2 respectively at the corrosion resistant plate two ends, utilizes two through holes lock body and enclosing cover inner surface can be installed together.Lock core is a cylinder cylindrical shell wide at the top and narrow at the bottom, be the diameter of the diameter of cylinder cylindrical shell upper end 9 greater than cylinder cylindrical shell lower end 7, on the upper end of cylinder cylindrical shell tube edge, be shaped on a pair of key 4, lock core is sleeved in the circular hole that rectangular recess central authorities are shaped on, be that cylinder cylindrical shell upper end is fitted on the upper surface of rectangular recess, cylinder cylindrical shell lower end is passed the bottom of rectangular recess and is welded together with the rectangle dead bolt.For the anglec of rotation that limits lock core is opened or locking with convenient, a limited block 6 is installed in outer end in the upper and lower side junction of the cylinder cylindrical shell of lock core, this limited block is inlaid in the 90 degree stopper slots that lock is shaped in 8, make lock core in 90 degree scopes, to rotate, thereby screw out locking and the open function of realizing pattern manhole cover lock in the locked groove that makes in the locked groove that lock core precession well seat is shaped on or be shaped on from the well seat, promptly spend the time-division other places in unlatching and locking states at 0 degree and 90.
This pattern manhole cover lock can be installed on the enclosing cover inner surface by the bolt mode, on the dislodging hole that covers outside the rectangular recess of pattern manhole cover lock is aimed at, uses this pattern manhole cover lock opener to open or the locking pattern manhole cover lock simultaneously.The structure of this pattern manhole cover lock opener is connected and composed by handle 11, column 12 as shown in Figure 3, and handle installs an end of column, and the projection 13 with the key coupling radially is installed in the other end both sides of column.This pattern manhole cover lock opener should be inserted in the key of pattern manhole cover lock by the dislodging through hole that covers outward, effect by projection makes lock core carry out 90 degree rotations, thereby screw out locking and the open function of realizing pattern manhole cover lock in the locked groove that makes in the locked groove that lock core precession well seat is shaped on or be shaped on from the well seat, the projection at two ends, pattern manhole cover lock opener bottom can tangle the enclosing cover inboard and carries out opening or fastening of enclosing cover simultaneously.
It is emphasized that; embodiment described in the utility model is illustrative; rather than it is determinate; therefore the utility model is not limited to the embodiment described in the specific embodiment; every by those skilled in the art according to other embodiments that the technical solution of the utility model draws, belong to the scope of the utility model protection equally.
