Abstract

An open and close device for door panels of a safe inner box comprises a door panel (1) used for closing and opening the inner box, and is characterized in that the door panel (1) can be arranged in slide rails (5) on the left side and the right side of the inner box opening in an up-and-down sliding manner; the slide rails (5) extend to the lower part of the inner box opening, and the distance (H) of the slide rails (5) extending downwards from the inner box opening is at least larger than or equal to the height of the door panel (1); a lock disc (2) which can rotate during open and close processes is arranged at the middle part of the door panel (1); the upper end and the lower end of the lock disc (2) are respectively and movably connected with one end of respective bolts (3); and when the bolts (3) extend out, the other ends of the bolts (3) are inserted in limited blocks (4) in corresponding positions on the left side and the right side of the inner box opening. Compared with the prior art, the utility model has the advantages that the utilization rate of the inner box of the safe is high, and the unnecessary space for a drawer is eliminated; furthermore, the firm structure of the door panel of the inner box can still play a better prevention effect, thereby realizing double-insuring effect; and the use is convenient, and the inner box can be opened through the dead weight of the door panel only if the lock disc is opened.

Description

The closing and opening device of chamber door plate in the strongbox

Technical field

The utility model relates to a kind of strongbox production technical field, especially refers to the closing and opening device of chamber door plate in the strongbox.

Background technology

In the existing strongbox, be designed to drawer mostly, so that deposit different types of thing, but adopt the shortcoming of drawer, drawer itself will occupy the certain space of strongbox, if there are a plurality of drawers will occupy space in the more strongbox, thereby reduces the utilization rate of strongbox; Also have, adopt the fastness of drawer lock device not enough, it is just very low to play two road safety effects.Is by casing as the patent No. for its structure of Chinese utility model patent that the CN93245381.3 name is called " wall type strongbox ", the case header board, plate behind the case, drawer, chamber door and coded lock are formed, for overcoming the defective that existing wall type strongbox is installed in the strong and fire line difference of fastness on the body of wall, the size of plate is greater than the size of casing respective face behind the utility model raising middle flask header board and the case, make it before casing forms, the back edge projection, middle recessed structure, outside at chamber door is provided with one deck labeled door again, and constitute interlayer between the chamber door, therefore this wall type strongbox can wholely embed and be installed in the body of wall, fastness is good, and has simple in structure, the advantage that fire line is good.But its shortcoming is the same with above-mentioned prior art, takes up space and reduces the utilization rate of strongbox.So can improve utilization of space in the insurance, the safety effect of case has become the important topic of exploitation in strengthening again.

Summary of the invention

Technical problem to be solved in the utility model is the closing and opening device that chamber door plate in the strongbox that a kind of case volume easy to use, interior is big and structure is more firm is provided at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the closing and opening device of chamber door plate in this strongbox, include the door-plate of case in being used to seal and open, it is characterized in that: described door-plate can slide up and down to place on the slide rail of interior case mouth the right and left, case mouth below in this slide rail extends to, and the distance that slide rail extends downwards from interior case mouth is at least more than or equal to the height of door-plate, rotating lock collar when the door-plate middle part is provided with opening and closing, the upper and lower side of this lock collar is connected movably with an end of keeper separately respectively, and when keeper stretched out, the other end of keeper was plugged on the limited block that is positioned at case mouth the right and left relevant position separately.

As improvement, described lock collar is arranged on the inner surface of door-plate, and described keeper is positioned at the inner surface position of door-plate, and the tapered end on the lock collar extends to the external surface of door-plate from the middle part of door-plate.

Its lower end of above-mentioned slide rail is respectively arranged with the backing pin that prevents to fall under the door-plate.

Now improve, the left and right sides, door-plate the inside of described interior case also can be provided with guide shaft fixing unit again, and the guide shaft fixing unit perforate is passed for the keeper other end.

Compared with prior art, the utility model adopts door-plate can slide up and down to place on the slide rail of interior case mouth the right and left, case mouth below in this slide rail extends to, and the distance that slide rail extends downwards from interior case mouth is at least more than or equal to the height of door-plate, rotating lock collar when the door-plate middle part is provided with opening and closing, the upper and lower side of this lock collar is connected movably with an end of keeper separately respectively, and when keeper stretched out, the other end of keeper was plugged on the limited block that is positioned at case mouth the right and left relevant position separately.The advantage of this design is: the utilization rate height of case in the insurance, and that promptly saves drawer needn't the space; Also have, the door panel structure of interior case firmly and still can play the effect of well preventing, promptly forms the effect of two roads insurance; Also have, easy to use, as long as open lock collar, door-plate just can be opened interior case by deadweight, so the utility model is a kind of very practical product rational in infrastructure, is worthy of popularization.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1 to Figure 3, the closing and opening device of chamber door plate in the strongbox of present embodiment, include the door-plate 1 of case in being used to seal and open, described door-plate 1 can slide up and down to place on the slide rail 5 of interior case mouth the right and left, case mouth below in this slide rail 5 extends to, and the distance H that slide rail 5 extends downwards from interior case mouth is at least more than or equal to the height of door-plate 1, rotating lock collar 2 when door-plate 1 middle part is provided with opening and closing, the upper and lower side of this lock collar 2 is connected movably with an end of keeper 3 separately respectively, and when keeper 3 stretched out, the other end of keeper 3 was plugged on the limited block 4 that is positioned at case mouth the right and left relevant position separately.Above-mentioned lock collar 2 is arranged on the inner surface of door-plate 1, and described keeper 3 is positioned at the inner surface position of door-plate 1, and the tapered end 21 on the lock collar 2 extends to the external surface of door-plate 1 from the middle part of door-plate 1.And the lower end of slide rail 5 is respectively arranged with the backing pin 51 that prevents that door-plate from falling for 1 time.The left and right sides, door-plate 1 the inside of case also is provided with guide shaft fixing unit 11 in above-mentioned, and guide shaft fixing unit 11 perforates are passed for keeper 3 other ends.

Operating principle of the present utility model is:

At first open, the door of strongbox, and then with in the tapered end on the lock collar of key insertion door-plate, rotation lock collar, lock collar drive keeper and shrink, promptly door-plate is by conducting oneself with dignity along the slide rail downslide and opening interior case automatically.During the case mouth, as long as door-plate is upwards sliding, rotate lock collar then in needs are closed, two of keeper is stretched out and be inserted on the limited block, extract key again, the band door of insuring gets final product again.
