Detailed Description

The push type lock head of the metering box comprises an elastic hanging piece 4, a hanging bolt 2, a return spring 5 and a lock sleeve 3 (see the attached figures 1, 2 and 3 in the specification).

A flip cover 1 of the metering box is provided with a mounting bolt 2 (see the attached figure 1 of the specification). The lower end of the mounting bolt 2 is provided with a clamping block 10; the lower end face of the clamping block 10 is symmetrically provided with guide inclined planes 11; clamping bosses 12 are symmetrically arranged at the upper ends of the clamping blocks 10 at the two sides of the mounting bolt 2 (refer to the attached figure 6 in the specification).

A lock sleeve 3 is arranged on the box body of the metering box; the mounting bolt 2 and the lock sleeve 3 are mutually corresponding. When the batch meter is closed, the mounting bolt 2 can be inserted into the lock sleeve 3.

The lock sleeve 3 is movably provided with an elastic hanging piece 4 (refer to the attached figures 1 and 2 in the specification). The elastic hanging part 4 is of an integrated structure and comprises a positioning pin 7, an elastic fork 6, a clamping claw 8 and a guide boss 9 (see the description and the attached drawing 5). The fork openings of the elastic forks 6 can be mutually closed when stressed.

The middle part of the elastic fork 6 is provided with a positioning pin 7; a return spring 5 is arranged between the lower end of the positioning pin 7 and the bottom of the lock sleeve 3 (see the attached figure 2 in the specification); a positioning flange 19 is arranged at the center of the bottom of the lock sleeve 3; reset spring 5's upper end and locating pin 7 plug-in connection, lower extreme and 19 plug-in connections of locating flange, the aim at that so sets up: so that the return spring 5 can be positioned by the positioning flange 19 and the positioning pin 7, and the problem that the return spring is separated from the assembly station is avoided.

Clamping claws 8 are symmetrically arranged on the inner side of the upper end head of the elastic fork 6; the lateral surface of the outer side of the elastic fork 6 is symmetrically provided with a guide boss 9 (see the attached figure 5 in the specification); the elastic hanging piece 4 is connected with the inner wall of the lock sleeve 3 in a sliding way through a guide boss 9. The guide boss 9 is intermittently connected with the positioning insertion hole 18 on the lock sleeve 3 in a clamping way. The lower extreme face of direction boss 9 is slope column structure, so sets up the aim at of direction boss 9: so that the guide boss 9 is separated from contact with the positioning insertion hole 18 along the slope of the lower end surface in the downward movement process of the elastic hanging part 4 under the stress; therefore, the problem that the guide boss 9 cannot be separated from the positioning jack 18 in a clamping mode when the lower end face of the guide boss 9 is in a step shape can be avoided.

The gap between the clamping claws 8 of the elastic hanging and carrying piece 4 is larger than the width of the clamping block 10; the purpose of thus arranging the clamping block 10 is: when the clamping device works, when the clamping claws 8 correspond to the width of the clamping blocks 10, the clamping claws 8 can be inserted into the elastic hanging piece 4 from the space between the clamping claws 8; then, when the elastic hanging part 4 rotates 90 degrees, the clamping claw 8 of the elastic hanging part 4 corresponds to the clamping block 10, and the clamping block 10 is clamped and connected with the clamping claw 8.

Two groups of limiting bosses 13 are symmetrically arranged on the upper part of the inner wall of the lock sleeve 3; the lower end of the limiting boss 13 is connected with a long guide chute 15 through a short vertical chute 14; one side of the bottom of the long guide chute 15 is connected with a long vertical chute 16; the upper end of the long vertical chute 16 is connected with the short vertical chute 14 of the other group of limiting bosses 13 through a short guide chute 17; the middle parts of the two groups of long guide chutes 15 are provided with positioning insertion holes 18 (see the description and the attached drawing 8); the two groups of positioning insertion holes 18 and the two groups of limiting bosses 13 are arranged in a crisscross manner (see the attached figure 7 in the specification).

The elastic suspension 4 is slidably connected to the short vertical chute 14, the long guide chute 15, the long vertical chute 16 and the short guide chute 17 by the guide bosses 9 (see fig. 2, 3 and 4 of the specification).

When the push type lock head of the metering box is in an open state, the guide boss 9 of the elastic hanging piece 4 is abutted against the limiting boss 13 of the lock sleeve 3, and the elastic hanging piece 4 is located at the upper limit position. The clamping claw 8 of the elastic hanging piece 4 corresponds to the width direction of the clamping block 10 of the hanging bolt 2.

When the lock head is used for locking the metering box, the turning cover 1 is firstly closed, and the mounting bolt 2 is inserted into the elastic mounting piece 4. Then, the flip cover 1 is pressed downwards continuously, so that the mounting bolt 2 can press the elastic mounting piece 4 through the positioning pin 7 to overcome the elastic force of the return spring 5 and then descend. During the downward movement of the elastic suspension element 4, the guide projections 9 of the elastic suspension element 4 first enter the corresponding long guide chutes 15 along the short vertical chutes 14. In this way, when the guide boss 9 moves along the long guide chute 15, the elastic hanging member 4 will gradually rotate during the downward movement under the guidance of the guide boss 9 and the long guide chute 15. When the guiding boss 9 of the elastic carrying piece 4 rotates to correspond to the positioning insertion hole 18, the elastic fork 6 of the elastic carrying piece 4 is expanded under the action of the self elastic force, so that the guiding boss 9 is inserted into the corresponding positioning insertion hole 18. The elastic mount 4 is now held fixedly connected via the guide cams 9 and the positioning receptacles 18. At this time, the elastic hanging piece 4 just rotates 90 degrees, and the clamping boss 12 of the hanging bolt 2 is connected with the clamping claw 8 of the elastic hanging piece 4 in a clamping manner (see the attached figure 3 in the specification). Therefore, the aim of locking the flip cover 1 by clamping and fixing the mounting bolt 2 through the elastic mounting piece 4 can be achieved.

When the metering box is locked by using the lock head and needs to be opened, the turning cover 1 is continuously pressed, so that the mounting bolt 2 continuously extrudes the elastic mounting piece 4; after the elastic hanging piece 4 is stressed, the guide boss 9 is separated from the contact with the positioning insertion hole 18 and then continuously moves to the bottom of the long vertical sliding groove 16 along the long guide chute 15 (see the attached figure 4 in the specification). Then the flip cover 1 is released, and at the moment, the elastic hanging part 4 moves upwards under the action of the elastic force of the return spring 5; during the upward movement of the elastic hanging part 4, the guide boss 9 will move along the long guide chute 15 and finally enter under the limit boss 13 under the guidance of the short guide chute 17 to be in interference connection with the limit boss. In the process the elastic carriers 4 will rotate 90 degrees under the guidance of the long guide chute 15; at this time, the clamping claw 8 of the elastic hanging piece 4 corresponds to the width direction of the clamping block 10 of the hanging bolt 2. Then the flip cover 1 is lifted upwards and closed to separate the mounting bolt 2 from the elastic mounting piece 4.

The push type lock head of the metering box is compact in structure and ingenious in design, the lock head can be locked when being pressed once, and can be loosened when being pressed again, so that the problem that the existing metering box lock head is complex in operation is solved, and the metering box is particularly suitable for being frequently opened and is low in confidentiality and safety requirements.
