Description

  The present invention relates to an electric equipment storage cabinet having a structure in which a door is locked to a cabinet body with a lock bar.

  2. Description of the Related Art As an electrical equipment storage cabinet, a cabinet having a cabinet main body whose entire front surface is opened and a door that is provided on the front surface and that opens one side or double doors is widespread. The cabinet with this configuration is configured such that the closed door is locked by locking the upper and lower ends of the locking rod provided on the back of the door to the cabinet body by a handle operation provided on the door ( For example, see Patent Document 1).

Japanese Patent Laid-Open No. 11-146510

The above-mentioned conventional electrical equipment storage cabinet that locks the door with a locking bar is because the upper and lower sides of the door are locked to the main body by a locking bar extended by the operation of a handle provided at the approximate center on the open end side of the door. Even if the door is long in a simple operation, it can be locked and locked to the cabinet body.
However, the two rod rods constituting the locking rod are only supported at the back of the door by a support piece at one location in the vicinity of the tip, so that even if they are made of metal, they are easily bent when subjected to stress. When the door is subjected to a large force in the opening direction, the rod rod may be bent and disengage from the cabinet body.

  As a countermeasure for this problem, a configuration in which the rod rod is thickened or the rod rod is supported at a plurality of locations to prevent the occurrence of bending can be considered. A change is necessary, which causes a significant increase in cost. In addition, the configuration for supporting a plurality of positions of the rod rod is not practical because the operation of supporting the rod rod by inserting the support rod into the support member during assembly is not simple and the assembly process is complicated.

  In view of the above problems, an object of the present invention is to provide an electrical equipment storage cabinet that realizes a structure in which a rod bar constituting a locking bar is less likely to be bent by a slight design change.

In order to solve the above-mentioned problem, the invention of claim 1 operates a handle provided on the door of the cabinet so that the locking bar assembled on the back surface of the door expands and contracts to lock / lock the door with respect to the cabinet body. A cabinet for storing electrical equipment that can be unlocked, and the two rods constituting the locking rod are each a support member in which two places with a predetermined interval in the vicinity of the tip are fixed to the back of the door It is characterized by being supported by.
According to this configuration, since the two rod rods constituting the locking rod are supported at two locations with a predetermined interval, the rod rod is difficult to bend even when the door is subjected to stress in the opening direction. It becomes difficult to be unlocked. Moreover, since it is a structure which supports two places near the front-end | tip of a rod rod, it needs only a slight design change from the structure which supports only one conventional place. Furthermore, since the rod rod insertion operation is not significantly different from the conventional operation that is supported by insertion through one support member, the assembly operation of the locking rod is still easy.

According to a second aspect of the present invention, in the configuration of the first aspect, the support member has a pair of parallel support plates formed by bending a steel plate into a U-shape, and the support holes are formed in the support holes. The rod bar is inserted and supported to support two places, and the central flat portion arranged between the support plates forms a fixing surface that is fixed to the back of the door, and the pair of support plates are arranged 30 to 80 mm apart. It is characterized by being made.
According to this configuration, the distance between the pair of support plates is 30 to 80 mm apart, so that both the prevention of rod rod deflection and the workability of insertion and assembly can be achieved.

According to a third aspect of the present invention, in the configuration of the second aspect, one of the support holes formed in the pair of support plates is a long hole extending in a direction parallel to the door surface, and the other is a round hole. It is characterized by that.
According to this configuration, since the support hole on the handle side is a long hole, it is easier to insert the rod rod than in a state where both of the pair of support holes are round holes. In addition, since the long hole is long in the lateral direction parallel to the door, it can continue to support the rod rod well in the door opening / closing direction, and no rattling occurs in the front-rear direction, which is the door opening direction. .

  According to the present invention, since the two rod rods constituting the locking rod are each supported at two locations, even if the door is subjected to stress in the opening direction, the rod rod is not easily bent, and as a result, the door lock is released. It becomes difficult to be done. In addition, since two places close to the tip of the rod rod are supported, the rod rod insertion operation is not much different from the conventional operation of inserting one support member, and the rod rod assembly operation is still easy.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below in detail with reference to the drawings. FIG. 1 is an explanatory front view showing an example of an electrical equipment storage cabinet according to the present invention, and shows a state in which the opened front surface of the cabinet body 1 is closed by a door 2. A handle 3 is provided on the door 2, and a locking bar 4 connected to the handle 3 extends in the vertical direction on the back surface of the door 2. The locking rod 4 is composed of a pair of rod rods 4a and 4b. One rod rod 4a extends upward from the handle 3, and the other rod rod 4b extends downward from the handle 3. The rod rods 4a and 4b The front end is locked to the cabinet body 1 to prevent the door 2 from being opened. The vicinity of the top and bottom ends of the locking bar 4 is supported on the back surface of the door 2 by a support member 5.

FIG. 2 is an enlarged view of a portion A, and FIG. As shown in FIGS. 2 and 3, a tongue piece 11 that is connected to the rotating shaft 10 of the handle 3 and engages with the cabinet body 1 is provided on the back surface of the door 2 that is the rear portion of the handle 3. In addition, the base ends of the pair of rod bars 4a and 4b are connected to form the locking bar 4.
The locking rod 4 is constructed by axially attaching two rod rods 4a and 4b at a point-symmetrical position about the rotation shaft 10 of the handle 3, and when the door 2 is closed as shown in FIG. It is arranged at an angle of about 45 degrees around the rotation shaft 10 with respect to the horizontal direction, the connecting portion of the upper rod rod 4a is arranged above the rotating shaft 10, and the connecting portion of the lower rod rod 4b is below Is arranged. In this state, as described above, the rod rods 4a and 4b have their tips locked to the cabinet body 1 to prevent the door 2 from being opened.
When the door 2 is closed, the tongue 11 is also locked to the frame 1a formed around the opening of the cabinet body 1 as shown in FIG. Be blocked.

  From this state, when the handle 3 is turned about 60 degrees in the direction of the arrow P1, the locking bar 4 is retracted and the locking with the cabinet body 1 is released. At the same time, the tongue piece 11 is also rotated in the P2 direction, and the locking to the cabinet body 1 is released. Thus, the lock bar 4 is locked / unlocked with respect to the cabinet body 1 by the turning operation of the handle 3, and the tongue piece 11 is also locked / unlocked with respect to the cabinet body 1.

  FIG. 4 is a cross-sectional view taken along the line C-C, and FIG. As shown in FIGS. 4 and 5, a roller 8 is attached to the tip of the rod rods 4a and 4b so that the locking rod 4 that is extended / retracted can smoothly engage / disengage.

6A and 6B are explanatory views of the support member 5, in which FIG. 6A is a left side view, FIG. 6B is a front view, and FIG. 6C is a right side view. The front is set according to the front direction of FIG.
The support member 5 is formed by bending a steel plate into a U-shape, and is disposed on the back surface of the door 2 so that the bent pieces 5a and 5b at both ends are opposed to each other in the vertical direction, and the central flat portion 5c is welded or the like. It is a fixed surface that is fixed to the back surface of the plate. The bent pieces 5a and 5b thus fixed project from the rear and constitute a pair of support plates that support the rod bars 4a and 4b.

  The bent pieces 5a and 5b are formed with support holes 6 (6a and 6b) through which the rod rods 4a and 4b are inserted and supported. However, the support holes 6 are not identical in shape with the bent pieces 5a and 5b facing each other, and the support holes 6a formed in one of the bent pieces 5a arranged on the handle 3 side are long holes, and the rod rods 4a and 4b. The support hole 6b formed in the other bent piece 5b on the distal end side of this is a round hole.

  The support hole 6a, which is a long hole formed in one bent piece 5a, is formed long in the lateral direction, that is, long in the left-right direction parallel to the surface of the door 2. Moreover, in FIG. 6, the space | interval (outside dimension) W1 of the bending pieces 5a and 5b is formed 35 mm apart.

In this way, the two rod bars 4a and 4b constituting the locking bar 4 are supported at two positions with a predetermined interval, so that the rod bars 4a and 4b can be applied even when the door 2 is stressed in the opening direction. Becomes difficult to bend and the lock of the door 2 is difficult to be released. Moreover, since it is a structure which supports two places close | similar to the front-end | tip of rod rod 4a, 4b, it needs only a slight design change from the structure which supports only one conventional place. Further, since the insertion work of the rod bars 4a and 4b is not significantly different from the work supported by the conventional single support member 5 by insertion or the like, the assembly work of the locking bar 4 is still easy.
Further, the distance between the pair of bent pieces 5a and 5b is 35 mm apart, so that both the prevention of bending of the rod rods 4a and 4b and the workability of inserting and assembling can be achieved. The distance between the bent pieces 5a and 5b does not have to be 35 millimeters. If the bent pieces 5a and 5b are arranged 30 to 80 millimeters apart, the rod rods 4a and 4b can be prevented from being bent and the lock rod 4 can be assembled easily. Can be compatible.
Further, since the support hole 6 on the handle 3 side is a long hole 6a, it is easier to insert the rod rods 4a and 4b than when both the pair of support holes 6 are round holes. . Further, since the long hole 6a is long in the lateral direction parallel to the door 2, the rod rods 4a and 4b can be supported well in the opening and closing direction of the door, and the back and forth direction, which is the opening direction of the door 2, rattles. Will not occur.

  In addition, although the support hole 6 formed in the support member 5 forms one side by the side of the handle | steering-wheel 3 as the long hole 6a, both are good also as a long hole. Furthermore, the rod rods 4a and 4b can be inserted easily and effectively compared to the case where both ends of the rod rods 4a and 4b are made into the long holes 6a with the hole shapes being reversed, but both are round holes.
