Description

  The present invention relates to a mounting structure for a handle locking device used for a door of a storage box or the like of various devices.

  An example of a known device having a handle locking device attached to a door is described in FIG. 7, FIG. 8 and FIG. 9 of Patent Document 1 and the specification [0026]. This is because the packing member interposed between the peripheral surface of the door mounting hole (FIG. 9) formed in a rectangular shape and the outer periphery of the fixing case of the lock handle device for the door (form along the mounting hole) from the door. Prevents inundation such as rainwater.

  A similar technique is also described in [FIG. 4] and specification [0008] of Patent Document 2.

  However, techniques similar to these are shown in FIGS. 1 and 2, in which the clasp 102 of the handle locking device 101 installed on the door 100 is tightened and locked to the receiving portion 104 of the box body 103. The stress (arrow) generated at the time of tightening is directed in the direction of the arrow of the handle shaft 107 to which the handle locking device 101 is attached from the metal receiving portion 104 that holds the clasp 102, and the reaction force is the handle locking device. In order to appear as a reaction force on the upper and lower portions of the door 100 through packings 105 positioned above and below 101, the door 100 around the vertically long attachment hole 106 is bent and deformed.

  Due to this deformation, the water stop function between the mounting hole 106 and the packing 105 becomes insufficient, which not only causes corrosion of the door lock handle device 101, but also adversely affects various devices in the box body. There was a problem.

  Therefore, the present invention is to solve the above-described problems, and it is an object of the present invention to increase the strength of the door where the handle locking device is attached and to improve the sealing performance between the device and the door.

  The gist of claim 1 of the present invention lies in the form of a door mounting hole to which the handle locking device is attached, and a main body for mounting the handle locking device to the door, and a handle base having at least a handle shaft fitted therein. By limiting to the through holes with the mounting screw holes, the seal is limited to the periphery of each through hole, which has a smaller area than the seal on the wide surface of the door surface where the packing mounting holes are provided so far. Thus, the handle locking device mounting structure increases the waterproof effect by reducing the bending deformation in the mounting hole.

  A handle lever pivotally attached to a handle shaft that is housed and locked in the handle base is rotated with a separately provided key to release the rotation of the locked handle shaft. Thus, by pulling and rotating the handle lever from the handle base, the clasp installed at the tip of the handle shaft is locked and unlocked to the receiving portion of the box body. In this case, it is possible to prevent water from entering the door surface by covering all the rotor-type lock projections with the above-described packing.

  On the door side of the packing between the handle base and the door, there are a periphery of the protrusion of the handle base, a periphery of the body mounting screw hole at the vertical position of the handle base, and the entire periphery of the handle base. By providing the protruding edge portions having the same height, the effect of preventing water from entering between the door and the handle base is increased.

  By making the outer periphery at the top of the protruding edge portion higher than the inner periphery, the surface seal at the top was changed to a linear seal.

  When locking the door to which the handle locking device is attached to the box body, by providing a through hole that penetrates at least the protrusion on the back of the handle base and the body mounting screw hole on the attachment door, The area where the through holes are added is smaller than the area where the mounting holes that are slightly smaller than the outer periphery are provided, and the stress concentration around the through holes at the time of locking is dispersed to reduce the bending of the door around the handle locking device. Increase the waterproofing effect of the part.

  When the handle locking device has a rotor-type lock projection, the projection is covered with a packing to prevent water from entering from the door surface.

  The door side of the packing between the handle base and the door has the same height around the protrusion of the handle base, around the body mounting screw holes above and below the handle base, and around the entire handle base. By providing the projecting edge part, it is possible to prevent the water from entering between the door and the handle base by concentrating stress on the projecting edge part.

  By making the outer periphery at the top thickness of the protruding edge portion higher than the inner periphery, the sealing force between the door around each through hole and the handle locking device can be increased.

FIG. 9 is a plan view of the packing used in the present invention. FIG. 10 is a rear view of FIG. 9. It is BB sectional drawing of FIG.

  When the handle locking device is attached to the door, until now the seal of the device has been sealed along one vertically long mounting hole provided in the door. However, in the present invention, the mounting hole for attaching the handle locking device to the door is provided. The main body is attached via the door by providing a through hole in the door that penetrates at least the main body mounting screw hole of the device and the protrusion on the back surface of the handle base. A screw is screwed into the screw hole, and the packing of the handle locking device is pressed against the peripheral surface of each through hole.

  As shown in FIGS. 3 to 6, main components of the handle locking device 3 installed on the door 1 include a handle base 4, a handle shaft 6, a handle lever 5, a stopper 7, and a packing 10. The definition of the locking device 3 here does not mean that the rotor lock is locked and unlocked by a key, but simply has a function of opening and closing the door 1 from the box body 2. .

  Therefore, the handle shaft 6 is fitted into the annular receiving groove 14 penetrating the handle base 4, and the tip portion of the handle shaft 6 is pivoted on the pivot 15 provided on the annular receiving groove 14 provided at the base of the shaft 6. The handle shaft 6 is rotated by pulling the handle lever 5 being worn out of the handle base 4 and turning it. A stopper 7 is fixed to the tip of the handle shaft 6 with a screw 12 via a washer 16, and a locking protrusion (not shown) is provided on the outer periphery of the protrusion 8 on the back side of the handle base. A control plate 17 having a 90-degree cutout groove (not shown) that rotates around the protrusion together with the stopper plate 7 controls the rotation within the range of 90 degrees, whereby the handle lever 5 controls the handle. The shaft 6 is rotated and rotated from FIG. 7 to FIG. 8 so that the stopper 7 of the door 1 is unlocked from the receiving portion 11 of the box body 2 and is reversely rotated from FIG. 8 to FIG. Thus, a known mechanism such as a configuration in which the stopper plate 7 is locked to the receiving portion 8 is locked.

  A rotor-type lock projection 13 is provided at the bottom of the handle base 4, and a handle lever pivotally attached to the handle base 4 is rotated by a separately prepared key so that the handle lever 4 can be moved from the receiving portion 8 of the stopper plate 7. Allows for opening and withdrawal.

  On the other hand, two main body mounting screw holes 18 are provided in the upper and lower portions of the handle locking device 3, and the concave metal receiving portion 11 provided in the box main body 2 by the upper and lower main body mounting screws 9 from the back side of the door 2. Corresponding to the position, it is fixed to the surface of the door 1.

  The main part of the present invention is located between the door 1 and the handle base 4 and has a packing 10 attached to the handle locking device 3 side, but the door 1 is not a conventional vertically long mounting hole, As shown in FIG. 3, through holes 19 and 19 ′ of the door through which the main body mounting screw 9 is passed through the upper and lower main body mounting screw holes 18, and through holes 19 ″ through which the handle base protrusion 8 fitted with the handle shaft 6 is passed. And a through hole 19 ″ ′ through which the rotor-type lock projection 13 of the handle base 4 passes. Note that the total area of these through holes is smaller than the area of the previous mounting holes.

  In this case, the packing 10 attached to the back surface of the handle locking device 3 is located between the door 1 and the handle base 4 as shown in FIG. On the door 1 side of the packing of FIGS. 9 and 11, the outer shape of the plane (FIG. 9) and the rear surface (FIG. 10) is substantially the same shape as the plane shape of the handle base 4, and the protruding edges on the entire circumference thereof. The upper longitudinal section has a thickness of a double linear endless seal portion 53 in which the height of the inner peripheral end 52 is lower than the height of the outer peripheral end 51. Further, in the upper and lower sides of the packing 10, the inner peripheral end 55 is lower in the longitudinal section than the outer peripheral end 54 in the longitudinal section in the vicinity of the hole 59 positioned around the main body attaching screw hole 18. A double linear endless seal portion 56 is provided on the outer periphery of the main body mounting screw hole, and is higher than the height of the screw hole 18 so as to be the same as the height of the seal portion 53. Further, the same cross-sectional shape as that of the seal portion 53 is also provided around the hole 60 located on the outer periphery of the handle base 4 and the height of the inner peripheral end 58 is lower than the height of the outer peripheral end 57 in the vertical cross section. I am doing. In this way, by making the outer peripheral end of the protruding edge portion protruding upward in the packing 10 higher than the inner peripheral end, a linear shape in which the portion in contact with the door 1 is doubled between the outer peripheral end and the inner peripheral end. The sealing effect is improved compared to the planar seal. The packing 10 is covered with a cover 61 on the entire outer periphery of the rotor type lock projection 13.

  Further, the right side of FIGS. 10 and 11 is a drawing of the side contacting the handle base 4 of the packing. By providing the reinforcing rib 62 on the handle base 4 side, not only the packing 10 itself is reinforced, but also the handle base. A part of the packing 10 is prevented from entering inside.

  In the mounting structure of the handle locking device according to the present invention having the above-described configuration, the handle locking device that penetrates the protrusion of the handle base of the locking device and the through hole of the packing located around the body mounting screw hole is attached to the door. Even if the handle shaft is turned and the clasp at the tip of the handle shaft is tightened and hooked on the receiving portion of the box body, the area of the hole plus each through hole is the handle lock on the door of the conventional product It is smaller than the area of the mounting holes of the device and is dispersed. In addition, in the present invention, the peripheral surface of each through hole is sealed with a packing attached to the handle locking device, so that the stress applied to the handle shaft at the time of tightening can be reduced with the reaction force against the stress of the through hole having a small area. By dispersing around, the door can be prevented from being greatly deformed by the locking device, and intrusion of water leaks into the door as much as possible.

Also, on the door side of the packing, a protrusion that presses the door around the protrusion of the handle base into which the handle shaft is fitted, the periphery of the body mounting screw holes above and below the handle base, and the entire periphery of the handle base By providing the edge portion, a surface water stop effect is enhanced between the door side of the periphery and the outer periphery and the handle locking device.
Furthermore, the outer periphery of the upper cross-section of the projecting edge is made a line higher than the inner periphery, and the sealing effect is achieved by compressing with a double line of the door side, the outer periphery with a higher line and the inner periphery with a lower line. Can be more sufficient.

  INDUSTRIAL APPLICABILITY The present invention is used for an attachment structure of a handle locking device used for a door of a box body such as a switchboard or various instruments.
