Abstract
The utility model relates to an improved knob lock comprising a lock assembly, a head seat, a fix cap shaped like a mortar board, an outer spring assembly, and a square tube, wherein the head seat is connected with the fix cap, and one end part of the square pipe passes through a central hole of the out spring assembly. The improved knob lock is characterized in that a positioning block is arranged inside the fix cap; at least two grooves are formed on the positioning block in the axial direction of the external diameter; bulges matched with the grooves on the positioning block are formed on the inner wall of the fix cap; the bulges are just clamped in the grooves; through-holes are formed on the positioning block and are matched with the external diameter of the square pipe; a buckle is arranged on the external diameter of the end part of the square pipe, which is stuck into the outer spring assembly; a cone spring is arranged between the buckle and the fix cap; and the diameter of the end of the cone spring, which is in contact with the buckle, is smaller than the external diameter of the buckle. By adopting the structure, the positioning block has certain thickness, so that the knob lock is abandoned caused by excessive damage after long-term service is prevented.
Description
Technical field
The utility model belongs to a kind of lockset, is specifically related to a kind of spherical door lock.
Background technology
Existing lockset is of all kinds, correlation technique about the door lock aspect, basically similar, such as the disclosed a kind of type gate of utility model patent (CN200720106351.6) lock is comprised lock body, lock core, inside and outside handle, interior overcoat dish, spring base, the four directions pipe, dead bolt etc., wherein interior overcoat dish is installed in the front and rear of lock body respectively, the spacing of two baffle plates equals the thickness of door, spring base flexibly connects with the four directions pipe, be provided with spring and stator between the two, the four directions pipe is connected with dead bolt, after key insertion lock core is opened, turn the handle, drive spring base, four directions pipe and dead bolt interlock make dead bolt retraction lock body, door is opened the most at last, the weak point of this door lock: stator is owing to be laminated structure, in long-term use since cubic pipe when rotating to its wearing and tearing that cause, cause stator damaged easily, make the function of lock scatter and disappear.
Summary of the invention
Technical problem to be solved in the utility model is: on the technical foundation of existing door knob lock, provide a kind of wear-resistant improved door knob lock that can grow use.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of improved door knob lock, comprise lock group, headstock, the locking cap that is the mortar-board shape, outside groups of springs, four directions pipe, described headstock is connected with locking cap, the centre bore of outside groups of springs is passed in the end of described cubic pipe, it is characterized in that: described locking cap inside is provided with a locating piece, described locating piece is provided with at least 2 road grooves on the axial direction of its external diameter, the locking cap inwall is provided with the projection that matches with groove on the locating piece, projection just in time is stuck in the groove, and described locating piece is provided with the through hole that is complementary with cubic external diameter of pipe.
On the external diameter of the end of groups of springs a buckle is set outside described cubic pipe stretches into, is provided with volute spring between described buckle and the locking cap, the contact jaw diameter of described volute spring and buckle is less than the buckle external diameter.
Described four directions pipe is provided with spring and covers the inside cover that offsets with spring one end outside spring with the contact jaw of interior cover dish, and described inside cover is provided with the through hole that is complementary with cubic external diameter of pipe.
Adopt said structure, the locating piece outer radius is provided with at least 2 road grooves, when locating piece placed locking cap inner, the locking cap inwall was provided with the projection that matches with groove on the locating piece, and projection just in time is stuck in the groove, projection can prevent then that in groove locating piece from arbitrarily rotating in locking cap, be fixed on locking cap inside,, can guarantee under long-term user mode because locating piece has certain thickness, can the transition breakage, cause the door knob lock not use.Contact jaw at four directions pipe and interior cover dish is provided with spring, because both ends of the spring offsets with internal memory lid and turn-knob respectively, then provides a restoring force after handle reverses, and makes the door knob lock use convenient.
Description of drawings
Fig. 1 is an explosive view of the present utility model;
Fig. 2 is an assembled state sectional drawing of the present utility model.
The specific embodiment
Referring to Fig. 1, the utility model is the improvement for prior art, its integral body is by outer handle 14, lock group 1, outer tube 15, packing ring 16, overcoat dish group 17, middle core bar 18, headstock 2, the locking cap 3 (calling mortar-board in the following text) that is the mortar-board shape, locating piece 6, volute spring 10, buckle 9, outside groups of springs 4, four directions pipe 5, with four directions pipe 5 dead bolts that are connected (not indicating among the figure), inside cover 13, spring 12, interior cover dish 11, interior pipe 19, Internal handle 20, turn-knob 21 is assembled successively, improvements are: mortar-board 3 inside have additional one certain thickness locating piece 6, locating piece 6 is provided with at least 2 road grooves 7 on the axial direction of its external diameter, locating piece 6 is provided with the through hole that is complementary with four directions pipe 5 external diameters, when locating piece 6 places mortar-board 3 inside, mortar-board 3 inwalls are provided with the projection 8 that matches with groove 7 on the locating piece 6, projection 8 just in time is stuck in the groove 7, then can make locating piece 6 fixing can not arbitrarily rotations, because locating piece 6 has certain thickness, can guarantee under long-term user mode, can the transition breakage, cause the door knob lock not use, replace the existence of stator.
Referring to Fig. 1, Fig. 2, outside stretching into, four directions pipe 5 on the external diameter of the end of groups of springs 4 buckle 9 is set, be provided with volute spring 10 between buckle 9 and the mortar-board 3, volute spring 10 is less than buckle 9 external diameters with the diameter of buckle 9 contact jaws, buckle 9 is used for fixing the position of the contact jaw of volute spring 10 and buckle 9, make the volute spring 10 and the contact jaw of buckle 9 arbitrarily not to stretch, the centre bore of outside groups of springs 4 is passed in the end of four directions pipe 5, and can rotate within it, because the external diameter of buckle 9 is greater than the inner edge diameter of outside groups of springs 4 simultaneously, so buckle 9 in outside groups of springs 4, can not extract four directions pipe 5 out the ends restrict of four directions pipe 5.
Four directions pipe 5 coils 11 contact jaws with interior cover and is provided with spring 12 and covers the inside cover 13 that offsets with spring 12 1 ends outside spring 12, inside cover 13 is provided with the through hole that is complementary with four directions pipe 5 external diameters, the purpose that spring 12 is set here is in order to provide a restoring force after the handle rotation, automatically handle is returned to the origin-location, increases operating handle.
