Abstract
The utility model provides an explosion-proof control box chamber door positioner, its main points are: the positioning device comprises a slope beam and a positioning shaft sleeve; the slope beam is in a slope shape at the bottom of the beam, the top of the slope beam is fixed on the side surface of the side door opening and closing side, and the bottom of the slope beam points to the outer side surface of the side door opening and closing side; the positioning shaft sleeve is fixed on the outer side surface of the side door opening and closing edge and at a position corresponding to the slope beam, wherein the corresponding position means that the positioning shaft sleeve can enter the slope bottom of the slope beam when the door is closed and the door edge is not attached to the door opening edge; the slope of the slope beam is defined in a way that when the door edge is attached to the door edge, the positioning shaft sleeve enters the slope of the slope beam, and the two groups of bolt holes can be aligned one by one. The utility model has the advantages that: the two-stage bolt holes are automatically aligned; when the door is locked, each bolt is free from shearing force, and the service life of the bolt is prolonged.
Description
Technical Field
The utility model relates to an explosion-proof control box specifically is positioner of explosion-proof control box chamber door.
Background
The explosion-proof control box comprises a box body, a box door, a door hinge and a bolt type box door lock, wherein the box body comprises a door opening edge (an outward flanging); the periphery of the box door is provided with a box door edge which corresponds to the door opening edge; a group of bolt holes are respectively arranged on the door opening edge and the door edge to form a circle, the two groups of bolt holes are in one-to-one correspondence, each pair of bolt holes is correspondingly provided with a bolt, and the bolt holes form a bolt type door lock of the box; the box door is folded around the door to realize opening and closing, and the box door edge comprises a folding side box door edge and an opening and closing side box door edge opposite to the door folding side, and correspondingly, the door opening edge also comprises an opening and closing side door opening edge. After the door edge of the box door is attached to the door edge after the box door is closed, two groups of bolt holes on the door edge and the box door edge are aligned one by one, and the box door is locked by sequentially screwing the corresponding bolts into the aligned bolt holes. For satisfying explosion-proof technical requirement, general box and chamber door are all very thick and heavy, and door fold paper self needs certain fit clearance again, when the chamber door is in the time of opening, the chamber door is in non-fixed free state except that door fold paper side, the chamber door receives gravity to slightly sink, will slightly sink the chamber door and close, these two sets of bolt holes must show the dislocation on case door limit and gate edge, need exert external force and lift the chamber door for this reason in the reality, after two sets of bolt holes one-to-one, use the bolt hole that aligns of corresponding screw bolt screw in proper order under keeping the external force condition, remove external force again after locking the chamber door. When the bolt type box door lock is locked, the weight of the box door still does not disappear, the weight is unloaded onto the bolts, each bolt is subjected to shearing force, and the service life of the bolt can be shortened.
Disclosure of Invention
In order to solve the technical problem, the utility model aims at providing an explosion-proof control box chamber door positioner.
The purpose of the utility model is realized like this: it includes door mouth limit, chamber door and case door limit, and the chamber door limit includes switching side case door limit, and the door limit includes switching side door mouth limit, characterized by: it also includes slope beam and positioning shaft sleeve; the slope beam is in a slope shape at the bottom of the beam, the top of the slope beam is fixed on the side surface of the side door opening and closing side, and the bottom of the slope beam points to the outer side surface of the side door opening and closing side; the positioning shaft sleeve is fixed on the outer side surface of the side door opening and closing edge and at a position corresponding to the slope beam, wherein the corresponding position means that the positioning shaft sleeve can enter the slope bottom of the slope beam when the door is closed and the door edge is not attached to the door opening edge; the slope of the slope beam is defined in a way that when the door edge is attached to the door edge, the positioning shaft sleeve enters the slope of the slope beam, and the two groups of bolt holes can be aligned one by one.
When the slightly sunken box door is closed and the edge of the box door is not attached to the edge of the door opening, the positioning shaft sleeve enters the slope bottom of the slope beam. And continuously closing the box door, operating the slope beam on the positioning shaft sleeve, gradually lifting the box door, laminating the door edge to the door edge, aligning the two groups of bolt holes one by one, and sequentially screwing the corresponding bolts into the aligned bolt holes to lock the box door. After the bolt type box door lock is locked, the weight of the box door is unloaded onto the box body through the slope beam and the positioning shaft sleeve, and the bolt does not bear the weight of the box door.
Compared with the prior art, the utility model has the positive effects that: the two-stage bolt holes are automatically aligned, so that the locking operation of the bolt type box door lock becomes simple and labor-saving; when the door is locked, each bolt is free from shearing force, and the service life of the bolt is prolonged.
Drawings
The present invention will be further described with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of the present invention.
Fig. 2 is an enlarged view of a portion a of fig. 1.
Detailed Description
The side door comprises a box body 1 and a door opening edge thereof, a box door 2 and a box door edge thereof, wherein the box door edge comprises an opening and closing side box door edge 21, the door opening edge comprises an opening and closing side door opening edge 11, and the side door further comprises a slope beam 3 and a positioning shaft sleeve 4; the slope beam is in a slope shape at the bottom of the beam, the top end 32 of the slope beam is fixed on the side surface of the side door of the opening and closing side, and the bottom end 31 of the slope beam points to the outer side surface of the side door opening edge of the opening and closing side; the positioning shaft sleeve is fixed on the outer side surface of the side door opening and closing edge and at a position corresponding to the slope beam, wherein the corresponding position means that the positioning shaft sleeve can enter the slope bottom of the slope beam when the door is closed and the door edge is not attached to the door opening edge; the slope of the slope beam is defined in a way that when the door edge is attached to the door edge, the positioning shaft sleeve enters the slope of the slope beam, and the two groups of bolt holes can be aligned one by one.
When the slightly sunken box door is closed and the edge of the box door is not attached to the edge of the door opening, the positioning shaft sleeve enters the slope bottom of the slope beam. And continuously closing the box door, operating on the positioning shaft sleeve by the slope beam, gradually lifting the box door, when the edge of the box door is attached to the edge of the door opening, aligning the two groups of bolt holes one by one, and at the moment, sequentially screwing the corresponding bolts 5 into the aligned bolt holes to lock the box door. After the bolt type box door lock is locked, the weight of the box door is unloaded onto the box body through the slope beam and the positioning shaft sleeve, and the bolt does not bear the weight of the box door. 6 is a door hinge.
