Abstract

The utility model relates to a door opening mechanism which comprises a fixed movable guide rail on a cabinet, a rolling wheel and a pry bar; the pry bar is also provided with a prying point support and a support roller; one end of the pry bar is articulated with the shell of the cabinet, and the other end is articulated with the rolling wheel; the rolling wheel is matched with a door; the prying point support is articulated with the support roller; the support roller is matched with the guide rail; the guide rail is bent into an angle shape. Because of the structure, when the cabinet descends in the shell, the support roller moves in the guide rail, the pry bar rotates relatively to the shell, the rolling wheel moves from the lower part to the upper part of the door, the door rotates around the shell and is opened; on the contrary, when the cabinet moves upwards, the support roller moves down relatively to the guide rail, the rolling wheel on the pry bar moves from the upper part to the lower part of the door, and the door is closed. Therefore, the mechanism can effective open or close the door.

Description

A kind of door-opening mechanism

Technical field

The utility model relates to the device that a kind of locker is used, especially a kind of door-opening mechanism of locker.

Background technology

Present prior art, the locker of an automatic lifting comprise automatic hoisting mechanism, the door body of housing, cabinet, cabinet, and the top of door body and the top of housing articulate.During use, after cabinet descends, need strike a body with the hand; Cabinet after rising is put back to the door body.Existing problems: can not open or close a body automatically, use inconvenient.

Summary of the invention

The purpose of this utility model is: a kind of door-opening mechanism is provided, and it can overcome deficiency of the prior art effectively, when cabinet descends, beats opening door body automatically, and cabinet rises when resetting, door body self-closing doors body.

The utility model is achieved in that a kind of door-opening mechanism, and its special character is: comprise that one is fixed on the guide rail on the movable cabinet, and scroll wheel, ripping bar also has sled point support and support roller on the ripping bar; The housing of described ripping bar one end and cabinet articulates, and the ripping bar other end is articulated with scroll wheel, and scroll wheel cooperates with the door body; A sled point support and a support roller articulate, and the support roller cooperates with guide rail; Guide rail is bent into dihedral.

Described a kind of door-opening mechanism, its special character is: ripping bar with by the pivot joint of a pin joint seat and housing.

Described a kind of door-opening mechanism, its special character is: a gathering sill is arranged on the guide rail, and the support roller is positioned at gathering sill.

A kind of door-opening mechanism of the utility model comprises the guide rail on the movable cabinet of fixing, scroll wheel, and ripping bar also has sled point support and support roller on the ripping bar; The housing of described ripping bar one end and cabinet articulates, and the ripping bar other end is articulated with scroll wheel, and scroll wheel cooperates with the door body; A sled point support and a support roller articulate, and the support roller cooperates with guide rail; Guide rail is bent into dihedral.Owing to adopt such structure, when cabinet descended in housing, the support roller moved in guide rail, and ripping bar rotates with respect to housing simultaneously, and scroll wheel is moved by the top of the bottom Xiang Menti of door body, used the door body to rotate around housing, and beat opening door body; Otherwise the cabinet support roller that moves up moves down with respect to guide rail, and scroll wheel is moved to the bottom by door body top on the ripping bar, then closes a body.So it can open or close a body effectively.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As Fig. 1, Fig. 1-1, shown in Figure 2, a kind of door-opening mechanism comprises that one is fixed on the guide rail 2 on the movable cabinet 6, scroll wheel 3, and ripping bar 1 also has sled point support 11 and support roller 4 on the ripping bar 1; The housing 7 of described ripping bar 1 one ends and cabinet 6 articulates, and ripping bar 1 other end is articulated with scroll wheel 3, and scroll wheel 3 cooperates with door body 8; A sled point support 11 and a support roller 4 articulate, and support roller 4 cooperates with guide rail 2; Guide rail 2 is bent into dihedral.As Figure 1-1, a gathering sill 21 is arranged on the guide rail 2, support roller 4 is positioned at gathering sill 21.

Shown in Fig. 1-2, a ripping bar 1 and a pin joint seat 5 articulate, and pin joint seat 5 is fixedly connected with housing 7.

Fig. 2 is the figure that the utility model is in the state of closing the door.Fig. 3 is that the utility model is in door opening state figure.

The utility model in use, original state as shown in Figure 2, when connecting the work of power supply automatic hoisting mechanism, cabinet 6 moves down, and guide rail 2 is along with cabinet 6 moves down, ripping bar 1 rotates counterclockwise, support roller 4 moves up along guide rail 2, and scroll wheel 3 uses 8 motions of door body, leaves housing 7, and beat opening door body 8, as shown in Figure 3;

Otherwise when closing body 8, guide rail 2 moves up with cabinet 6, and support roller 4 moves down along guide rail 2, and this moment, ripping bar 1 clockwise rotated, and when support roller 4 arrived 21 places, oblique below of guide rails 2, then a door body 8 was closed, as shown in Figure 2.

The utility model is provided with one respectively in the both sides of cabinet 6 in use.
