Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in fig. 1 to 4, the middle suspension member of the flat iron lock rod of the single-door cabinet of the embodiment includes a lock rod suspension member 10, the whole lock rod suspension member 10 is in a U-shaped structure, the structure includes a base, a side wall is arranged at the rear side of the base, and a boss 19 arranged opposite to the base is connected to the top of the side wall; the base bottom surface 11 of the base is distributed with a concave frustum 12 and a screw hole 13 which is coaxial with the concave frustum 12, the front surface of the side wall is provided with a process concave platform 22 which is butted with the outlet of the screw hole 13, the upper part of the rear surface of the side wall is provided with a step surface 17, and the lower part of the rear surface is extended with a back surface 15 which is vertically connected with the base bottom surface 11.

The locking bar hanger 10 is arranged by taking the plane of the longitudinal central axis of the side wall as a symmetrical mirror image.

The locking rod pendant 10 is connected with the frame upright post 30 in a matching mode, when the locking rod pendant 10 is fixed on the frame upright post 30, the O-shaped ring 50 is installed in the concave frustum 12, the screw 40 is locked in the screw hole 13, and meanwhile the bottom surface 11 and the back surface 15 of the base are attached to the corresponding contact surfaces of the frame upright post 30, so that a sealing connection structure with two surfaces and one hole is formed.

The part of the screw 40 extending out of the screw hole 13 is avoided by the concave processing platform 22.

The base bottom surface 11 is provided with a plurality of first blind holes 14, and the back surface 15 is also provided with a plurality of second blind holes 16.

The boss 19 includes a working surface 20 disposed opposite to and parallel to the base bottom surface 11, and first chamfered surfaces 21 extend from both sides of the working surface 20.

The upper end of the rear surface of the step surface 17 is smoothly transited to the working surface 20 through a second chamfer surface 18.

The utility model discloses an implement the principle as follows:

the base bottom surface 11 is perpendicular to the back surface 15 and serves to position the latch bar hanger 10 for installation on the frame upright 30 of fig. 5. The concave frustum 12 is used for accommodating an O-shaped ring 50 and playing a role in combining and sealing the contact positions of the locking rod hanging piece 10, the through hole of the frame upright post 30 and the screw 40;

the bottom of the concave frustum 12 is provided with a screw hole 13, a process concave platform 22 is arranged at the outlet of the through hole, and the process concave platform and a screw 40 form the locking function of the locking rod pendant 10;

the step surface 17 is attached to the folded edge 303 of the frame upright 30 in fig. 5, and can play a role in assisting positioning and preventing rotation when the screw 40 locks the locking rod hanger 10;

the second chamfer surface 18 can reduce weight and avoid elastic resistance at the contact position of the foaming strip 601 after the door panel 60 is closed;

the working surface 20 is the position where the cylindrical pin 90 of the flat iron lock rod 80 stops, and the first chamfer surface 21 provides buffering for the cylindrical pin 90 to enter and leave, so that the locking action resistance is appropriate, and the closing and the opening are smooth.

The reserved

blind holes

14 and 16 are reserved on the bottom surface 11 and the back surface 15 of the base and are reserved for the expanded application of the lock rod hanging piece 10, and the reserved blind holes can be used as riveting holes of positioning pins and bottom holes of tapping, and are determined according to requirements.

As shown in fig. 3, the locking rod hanger 10 is a mirror image structure with a section a-a (i.e. a plane where a longitudinal central axis of a side wall of the locking rod hanger 10 is located) as a symmetrical plane, and on the base bottom surface 11, as can be seen from the installation example of fig. 5, when the locking rod hanger 10 is fixed on the frame upright post 30, the concave frustum 12 can accommodate the O-ring 50, the screw 40 is locked into the screw hole 13, the locking rod hanger 10 is fixed on the frame upright post 30, and simultaneously, the base bottom surface 11 and the back surface 15 are attached to corresponding contact surfaces of the frame upright post 30, so as to form a reliable sealing connection structure with one hole on both surfaces;

the exposed head of the screw 40 is avoided by the process concave station 22, and the weight of the locking rod pendant 10 is reduced on the premise that the process concave station 22 completes the functions of the screw. The step surface 17 and the second chamfer surface 18 are communicated, and the working surface 20 parallel to the base bottom surface 11 is positioned on the inner side of the boss 19 and is in tangential contact with the cylindrical pin 90 of the flat iron lock rod 80 in fig. 5, so that the door plate 60 is locked on the frame upright post 30. The first chamfer surface 21 guides the cylindrical pin 90 to enter and exit the working surface 20;

the provision of the second chamfer 18 is functionally necessary, and in fig. 5, the foam strip 601 is avoided, so that the closing resistance of the door 60 is reduced, and at the same time, the weight is reduced.

In the specific implementation process, as shown in fig. 5, on the premise that the known frame upright 30 and the door panel 60 are installed in place, and the lock rod guide 70, the flat iron lock rod 80 and the cylindrical pin 90 are all assembled in place, in the figure, the door panel 60 is closed, and the cylindrical pin 90 of the flat iron lock rod 80 enters the working state.

The door panel 60 should be in an open state when the latch hanger 10 is assembled.

Firstly, placing an O-shaped ring 50 into a concave frustum 12 of a base bottom surface 11 of a locking rod pendant 10, then enabling the base bottom surface 11 of the locking rod pendant 10 to be abutted against a first positioning surface 304 of a frame upright post 30, enabling a back surface 15 of the locking rod pendant 10 to be attached to a second positioning surface 302 of the frame upright post 30, enabling a step surface 17 to be attached to a folded edge 303, and enabling a screw hole 13 of the locking rod pendant 10 to be aligned to a round through hole 305 of the frame upright post 30, so as to realize primary surface positioning of the locking rod pendant 10 on the frame upright post 30;

then, an inner hexagonal wrench is sleeved into the head of the screw 40, the screw is locked into the screw hole 13 of the locking rod hanger 10 through the square through hole 301 and the round through hole 305 of the frame upright post 30, the exposed tail of the screw 40 is avoided by the process concave table 22 of the locking rod hanger 10, so that the locking rod hanger 10 is fastened on the frame upright post 30, and the rest locking rod hangers 10 are installed and repeated.

Because the number of the locking rod hangers 10 in the cabinet corresponds to the number of the cylindrical pins 90 of the flat iron locking rod 80 one by one, before the door panel 60 is closed, the positions of each locking rod hanger 10 and the cylindrical pin 90 on the flat iron locking rod 80 are staggered, after the door panel 60 is closed, the foaming strip 601 firstly contacts the overlapped edge 303 of the frame upright post 30, after elastic resistance is met, a door lock handle of the door panel 60 can be pulled to drive the flat iron locking rod 80, so that the cylindrical pins 90 riveted on the door lock rod can slide through the first chamfered surface 21 of the locking rod hanger 10 in a tangent mode, and after the flat iron locking rod 80 finishes a stroke, the door lock rod finally stays on the working surface 20 of the locking rod hanger 10 and keeps a tangent state.

The cabinet door 60 is uniformly and resiliently locked by a plurality of locking bar hangers 10 as shown in fig. 5.

The above description is for the purpose of explanation and not limitation of the invention, which is defined in the claims, and any modifications may be made within the scope of the invention.
