Abstract

The utility model discloses a three-point blocking-out control box door which mainly solves the problem that the traditional box door is easy to deform after long-term service. The three-point blocking-out control box door comprises a door body matched with a control box. A handle is arranged on the door body, the handle is interlocked with a door bolt arranged inside the door body and the door bolt is mounted on a stop mechanism. Lock bars are symmetrically arranged above and below the stop mechanism and are interlocked with the handle; the tail ends of the lock bars penetrate guide fixing frames, and the guide fixing frames are symmetrically fixed at the upper part and the lower part of the inner side of the door body. The three-point blocking-out is realized by the three-point blocking-out control box door through the cooperation of the lock bars, the door bolt and the stop mechanism; therefore, the deformation problem of the control box door due to the long-term service is avoided and the sealing performance of the control box is improved simultaneously.

Description

A kind of 3 screens operation chamber door

Technical field

The utility model relates to a kind of operation chamber door, a kind of specifically 3 screens operation chamber door.

Background technology

At present; When the operation chamber door cooperates with casing; Only some screens through the chamber door middle part match; The poor sealing that this kind fit system causes the two ends up and down of chamber door to cooperate with casing easily, rainwater gets into box house easily when running into sleety weather from the slit between casing and the chamber door, and the normal operation of casing is brought adverse influence.In addition, this kind structure is when operation chamber door when using for a long time, and the chamber door easy deformation has reduced the sealing performance of control box more.

The utility model content

The purpose of the utility model is to provide a kind of 3 screens operation chamber door, and this control box door cooperates with casing through 3 screens, has avoided the long-time problem on deformation that causes of using of operation chamber door, has improved the sealing performance of control box simultaneously.

The technical scheme that its technical problem of the utility model solution is taked is: a kind of 3 screens operation chamber door; Comprise the door body that cooperates with control box, it is characterized in that said door body is provided with handle; The keeper interlock that described handle is inboard with being located at a body, said keeper is installed on the stop mechanism; The above and below of said stop mechanism symmetry be provided with locking bar, described locking bar links with handle, the end of locking bar passes the guide securement frame; Said guide securement frame symmetry be fixed on the inboard upper and lower of a body.

Compared with prior art; The utlity model has following outstanding beneficial effect: through the acting in conjunction of locking bar, keeper and stop mechanism; Realize 3 clamping matching in upper, middle and lower between chamber door and the casing, effectively avoided the long-time problem on deformation that causes of using of operation chamber door; While, 3 screens can better improve the sealing performance of control box, prevented that rainwater from getting into box house from the slit between casing and the chamber door, the security reliability of the casing operation of increase.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the partial enlarged drawing at Q place among Fig. 1;

Fig. 3 is that the P of locking bar part under Fig. 1 chamber door locking state is to view;

Fig. 4 is that the P of locking bar part under Fig. 1 chamber door open mode is to view.

Among the figure: 1 body, 2 handles, 3 guide securement framves, 4 locking bars, 5 stop mechanisms, 6 keepers.

The specific embodiment

As depicted in figs. 1 and 2.A kind of 3 screens operation chamber door comprises the door body 1 that cooperates with control box, and said door body 1 is provided with handle 2, described handle 2 and the keeper that is located at a body 1 inboard 6 interlocks, and said keeper 6 is installed on the stop mechanism 5; The above and below of said stop mechanism 5 symmetry be provided with locking bar 4, described locking bar 4 and handle 2 interlocks, the end of locking bar 4 passes guide securement frame 3; The upper and lower that is fixed on a body 1 inboard of said guide securement frame 3 symmetries.

Like Fig. 3 and shown in Figure 4.When door body 1 is used with control box; Handle 2 and locking bar 4 interlocks; Handle 2 rotations can drive locking bar 4 and move up and down; Two locking bars 4 are fixed through guide securement frame 3 and control box shell under the control of handle up and down, realize 2 screens up and down, and middle stop mechanism 5 has been accomplished the screens of intermediate point.Through control box,, effectively avoided the long-time problem on deformation that causes of using of operation chamber door through 3 screens of operation chamber door; While, 3 screens can better improve the sealing performance of control box, prevented that rainwater from getting into box house from the slit between casing and the chamber door, the security reliability of the casing operation of increase.

The above; Some principles of the utility model just explain through diagrams; This manual be not be to the utility model be confined to shown in described concrete structure and the scope of application; So every the modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.

Except that the said technical characterictic of manual, all the other technical characterictics are those skilled in the art's known technology.

Claims

1. 3 screens operation chamber door comprises the door body that cooperates with control box, it is characterized in that, said door body is provided with handle, the keeper interlock that described handle is inboard with being located at a body, and said keeper is installed on the stop mechanism; The above and below of said stop mechanism symmetry be provided with locking bar, described locking bar links with handle, the end of locking bar passes the guide securement frame; Said guide securement frame symmetry be fixed on the inboard upper and lower of a body.
