Abstract

The utility model relates to a door lock the lock-tongue of which is retractable in the hardware product field. The utility model is composed of a lock shell, an outer guide sleeve, an inner guide sleeve, a lock core, a rotary shaft, a pin, a lock-tongue etc. The utility model aims at tightly locking the door or the cabinet. The key point lies in that a set of spiral guiding mechanism which is connected into being by the outer guide sleeve, the inner guide sleeve and the pin is arranged in the lock shell. The outer guide sleeve is fixed on the lock shell and the opening or closing is determined by two different rotation directions. In opening, the lock core rotates in anticlockwise direction. Under the pressure of the spring, the pin is forced to move straightly backwards along the spiral groove and the rotary shaft and the lock-tongue move simultaneously to be separated from the pressed cabinet frame. Then if users continue to rotate the lock core, the pin drives the rotary shaft to make 90 DEG circumference rotation along the outer guide sleeve. The lock-tongue rotates 90 DEG simultaneously. Finally, the cabinet door is opened. Rotating in the contrary direction can lock the cabinet door. The utility model with a compact structure can be used on the electric cabinet door which has a strict requirement of the sealing performance. Therefore, the utility model is a relatively ideal lock at present.

Description

The collapsible door lock of dead bolt

Affiliated technical field

The utility model relates to the hardware products field, is the collapsible door lock of a kind of dead bolt.

Background technology

At present, the door lock kind is more, but their dead bolts can not shrink.The cabinet special door that has, a kind of dead bolt of needs is collapsible, make a door door lock good with the cabinet binding ability, and does not appear on the market as yet so far.

Summary of the invention

The purpose of this utility model is, provides a kind of dead bolt collapsible door lock, combines not good enough problem with cabinet to solve door.

The above-mentioned purpose design scheme is such: be provided with a cover in the lock housing of door lock and worn by pin by outer bush, interior guide pin bushing, rotating shaft and to close the spirally-guided mechanism that forms, outer bush is to be fixed on the lock housing, and the closure or openness state is realized by two different rotary directions.Lock core rotates counterclockwise during unlatching, and guide pin bushing rotates in driving, under the pressure of spring, force pin along helicla flute backward straight line move, the same moved further of rotating shaft and dead bolt is thrown off compacted tank bracket; Be rotated further lock core, pin drives rotating shaft and does 90 ° of circumference rotations along outer bush, and dead bolt also rotates 90 ° synchronously, and the cabinet door is opened.Otherwise rotate, pin the cabinet door.It is comparatively reasonable, compact that this door lock arrangement designs, and sealing and tight lock better performances are applicable to the electric cabinet door lock that sealing performance is had relatively high expectations.

Description of drawings

Fig. 1 is the utility model organigram;

Fig. 2 is the right apparent structure schematic diagram of Fig. 1.

Sequence number among the figure: 1, lock housing, 2, outer bush, 3, pin, 4, interior guide pin bushing, 5, rotating shaft, 6, dead bolt, 7, sealing ring, 8, jump ring, 9, spring, 10, lock core, 11, draw and climb.

Referring now to above schematic diagram, its feature is described as follows: Fig. 1, the collapsible door lock of dead bolt shown in Figure 2 be by being made up of parts such as lock housing, outer bush, interior guide pin bushing, lock core, rotating shaft, pin, dead bolts, and the double dot dash line position among the figure represents that dead bolt moves right and opens 90 ° state.It is characterized in that being provided with in lock housing 1 guiding mechanism of a cover spiral, this guiding mechanism is worn to close by pin 3 by outer bush 2, interior guide pin bushing 4, rotating shaft 5 and is formed, and outer bush 2 is to be fixed on the lock housing 1; Lock core 10 links with interior guide pin bushing 4 interlocks, is provided with spring 9 between the two, and lock core 10 is fixing by jump ring 8 with lock housing 1.Pin 3 and the helicla flute in the interior guide pin bushing 4 are done with to linking, and rotating shaft 5 also is that interlock links with lock core 10.Lock housing 1 is provided with sealing ring 7 with the junction of lock core 10.Connect fastening drawing at lock housing 1 one ends by nut and climb 11, the other end is being connected and fixed dead bolt 6 by nut, pad.The closure or openness state realizes by two actions, and its difference is the direction difference of being rotated.The first element of opening: lock core 10 rotates counterclockwise, and guide pin bushing 4 rotates in driving, under the pressure of spring 9, force pin 3 to move along the helicla flute straight line, make rotating shaft 5 and dead bolt 6 move (see Fig. 1 double dot dash line position, dead bolt move right about 8mm) together, throw off compacted tank bracket.Then second action: promptly be rotated further lock core, pin drives rotating shaft and makes circumference along outer bush 2 and rotate 90 °, and dead bolt 6 also and then rotates 90 °, cabinet door be opened (Fig. 2 dead bolt rotates counterclockwise 90 °).Otherwise lock core clockwise rotates, and dead bolt goes back to original position.Change, pin travels forward along helicla flute to the right again, and part all resets, and pins the cabinet door, makes it be in closure state.

The specific embodiment

Lock core and lock housing fix with stainless steel jump ring 8 in structure, make it certain anti-readily removable facility not arranged with any instrument dismounting, and sealing ring 7 plays sealing and protective action.The rotation that opens and closes electric cabinet door and be the long key of interior triangle by being inserted in the lock core termination realizes, for example the key used always of attendant is such for this key, the cover upper lock core termination triangular in shape of crossing the threshold, the rotating certain angle door just is lockable or opens, and pulls drawing on the door again and climbs 11 and open the door.This dead bolt and the difference of this structure are that a dead bolt can shrink, and another dead bolt then can not shrink.Have the outward appearance novelty, compact conformation, the peculiar function that dead bolt is collapsible can be used on the higher electric cabinet door of sealing requirements.
