Description
Technical Field
The utility model relates to an open door structure before applying to the drop-down formula of standard machine case, especially an open door structure before the drop-down formula of aluminum alloy plug-in card formula controller machine case.
Background
The aluminum alloy card-inserting type controller case is widely used in various industries. In the design of opening the front panel, the hinge structure of the case directly influences whether the case is firm and beautiful. In order to open the panel smoothly. In the existing structure, the traditional hinge form is generally used, the hinge axis is usually arranged outside the door plate, the front panel is not smooth enough in the mode, and the hinge is complex and fine to manufacture. If the hinge axis is arranged at the inner side of the door panel, the opening and closing angle of the panel is limited, and a more complex hinge structure is often used.
SUMMERY OF THE UTILITY MODEL
The utility model discloses its purpose is just providing one kind and is applying to the pull-down formula front opening structure of standard machine case, has solved current pull-down formula front opening structure and has had its angle that opens and shuts that can restrict the panel, and the amount problem that hinge structure is complicated.
The technical scheme adopted for achieving the purpose is that the pull-down front opening door structure applied to the standard case comprises a panel, panel shaft pins are symmetrically arranged at two ends of the inner side of the panel, the panel shaft pins are connected with one end of a hinge rocker arm through screws, the other end of the hinge rocker arm is arranged on a side plate shaft sleeve, and the side plate shaft sleeve is fixedly arranged on the inner side of a side plate of the case through countersunk screws.
Advantageous effects
Compared with the prior art, the utility model has the following advantages.
The utility model has the advantages that, this structure is realized two rotational degrees of freedom of hinge structure by panel pivot and curb plate axle sleeve, makes the panel open smoothly and closed to this structure can consume less quick-witted case space with the help of original quick-witted case part, has simple structure, the characteristics of the installation of being convenient for.
Drawings
The invention is further described with reference to the following figures and examples.
Fig. 1 is a side view of the hinge of the case in an open state of the present invention;
fig. 2 is a side view of the hinge of the case in a closed state;
FIG. 3 is a view of a panoramic view of the front door of the cabinet of the present invention when opened;
fig. 4 is the view of the panoramic view of the front door of the case of the utility model when closed.
Detailed Description
The present invention will be further described with reference to the following embodiments and the accompanying drawings.
A pull-down front door opening structure applied to a standard case comprises a panel 5, as shown in figures 1-4, panel shaft pins 4 are symmetrically arranged at two ends of the inner side of the panel 5, the panel shaft pins 4 are connected with one end of a hinge rocker arm 3 through screws, the other end of the hinge rocker arm 3 is installed on a side plate shaft sleeve 2, and the side plate shaft sleeve 2 is fixedly installed on the inner side of a side plate 1 of the case through countersunk screws.
The hinge rocker arm 3 is made of aluminum alloy materials, the hinge rocker arm 3 is sleeved on the side plate shaft sleeve 2, and the hinge rocker arm 3 and the side plate shaft sleeve 2 can rotate relatively.
The side plate shaft sleeve 2 is made of 304 stainless steel materials, and the side plate shaft sleeve 2 is sleeved on the countersunk head screw.
The panel shaft pin 4 is made of 304 stainless steel, the depth of the connecting part of the panel shaft pin 4 and the hinge rocker arm 3 is larger than the thickness of the rocker arm, and an inner hexagonal groove is drilled on the end surface of the panel shaft pin 4 for being used for installing the panel shaft pin 4.
In the utility model, a countersunk screw hole is drilled below the side plate 1, and a countersunk screw is arranged on the hole so as to fix the side plate shaft sleeve 2; the hinge rocker arm 3 is made of aluminum alloy, the aperture of the end, connected with the side plate shaft sleeve 2, of the hinge rocker arm 3 is slightly larger than the outer diameter of the part, connected with the hinge rocker arm 3, of the side plate shaft sleeve 2, and the difference between the aperture of the end, connected with the panel shaft pin 4, of the hinge rocker arm 3 is smaller than 1mm, the aperture of the end, connected with the panel shaft pin 4, of the hinge rocker arm is slightly larger than the outer diameter of the part, connected with the panel shaft pin 4 and the; the side plate shaft sleeves 2 are made of 304 stainless steel, the inner diameters of the side plate shaft sleeves 2 are slightly larger than the diameters of countersunk screw holes in the side plates 1, the difference between the diameters is smaller than 1mm, and the wall thickness of a pipe at the part, connected with the hinge rocker arm 3, in the side plate shaft sleeves 2 is about 2 mm; the panel shaft pin 4 is made of 304 stainless steel, the depth of the connecting part of the panel shaft pin 4 and the hinge rocker arm 3 is larger than the thickness of the rocker arm, the difference between the depths is smaller than 0.5mm, and an inner hexagonal groove is drilled on the surface for fixing the panel shaft pin 4 so as to be used for installing the panel shaft pin 4.
When the structure of the utility model is implemented again, in the first step, countersunk screws are arranged in conical holes below the side plates 1 at the two ends and are used for positioning the side plate shaft sleeve 2 at the position of the side plate 1; secondly, mounting the side plate shaft sleeve 2 on a countersunk screw of the side plate 1; thirdly, the hinge rocker arm 3 is sleeved on the side plate shaft sleeve 2; fourthly, aligning a threaded hole for realizing a fixing structure of the panel shaft pin 4 with the other end hole of the hinge rocker arm 3; and fifthly, the panel shaft pin 4 passes through the hole on the hinge rocker arm 3 and is screwed into the shaft pin fixing hole of the panel 5.
