Example 1.

Referring to fig. 1-4, a lifting mounting bracket 1 for an upper air intake burner of a kitchen range is formed by a lifting mechanism 2 and a base 3, wherein a clamping groove 1-1 for hanging the upper air intake burner, a nozzle mounting part 1-2 for mounting a nozzle and a probe mounting part 1-3 for mounting an ignition needle 4 and a thermocouple 5 are arranged on the lifting mounting bracket 1, a blocking plate 1-4 is arranged above the nozzle mounting part 1-2, the projection of the blocking plate 1-4 is overlapped with the projection of the nozzle mounting part 1-3, and the upper surface of the nozzle mounting part 1-2 is used for mounting a nozzle 6.

Compared with the prior art, the lifting mounting bracket for the upper air inlet burner of the kitchen range has the main advantages that the lifting mounting bracket 1 is only used for lifting the nozzle 6, the ignition needle 4 and the thermocouple 5, the upper air inlet burner is detachably and overturned connected with the lifting mounting bracket through a slot, the lifting weight is low, the lifting mechanism is not easy to clamp, and the upper air inlet burner is convenient to detach and clean. The upper air inlet burner can avoid the difficulty of larger air passage and separate the air passage from the burner.

Moreover, as the projection of the blocking plate-4 is overlapped with the projection of the nozzle mounting part 1-2, when the lifting mounting bracket is in the sinking station, the nozzle mounting part 1-2 can be utilized to cooperate to avoid the hole site, when the lifting mounting bracket is in the lifting station, the blocking plate 1-4 can be utilized to cooperate to avoid the hole site, the nozzle blockage caused by cleaning is avoided, and the waterproof performance of each station state is ensured.

In this embodiment, the lifting mechanism 2 includes a spring 2-1, a positioning rod 2-2 and a positioning rail 2-3, the spring 2-1 is connected between the lifting mounting bracket 1 and the base 3 and provides an upward restoring force for the lifting mounting bracket 3, the positioning rail 2-3 is disposed on the lifting mounting bracket 1, one end of the positioning rod 2-2 is connected with the base 3, and the other end of the positioning rod 2-2 is movably inserted into the positioning rail 2-3 and moves along a track defined by the positioning rail 2-3 and is positioned with the positioning rail.

In this embodiment, a positioning rod mounting frame 7 is disposed on the base 3, a guiding groove 7-1 is disposed on the positioning rod mounting frame 7, one end of the positioning rod 2-2 is rotatably connected with the positioning rod mounting frame 7, and the other end of the positioning rod 2-2 passes through the guiding groove 7-1 and is spliced with the positioning rail 2-3, so that the other end of the positioning rod 2-2 can smoothly slide in a limited track of the positioning rail 2-3.

Referring to fig. 5 and 6, the positioning rail 2-3 is located at the front side of the nozzle mounting portion 1-2, and is composed of a first vertical section AB, a first inclined section BC, a second vertical section CD, a second inclined section DE, a third inclined section EF, a third vertical section FG, and a fourth inclined section GB, which are sequentially connected; the first inclined section BC is inclined upward to the left, the second inclined section DE is inclined downward to the right, the third inclined section EF is inclined upward to the right, and the fourth inclined section GB is inclined downward to the left; the transition of each section is provided with ase:Sub>A step (height difference) so that the positioning rod 2-2 can only run along the direction of A-B-C-D-E-F-G-B-A.

The lifting principle of the lifting mechanism 2 is as follows: the initial state is a normal working state, namely the lifting mounting bracket 3 is in a state of ascending station (a state protruding above the panel), at the moment, the other end of the positioning rod 2-2 is positioned at the point A, the gravity of the lifting mounting bracket 1 is counteracted due to the upward elastic force of the spring 2-1, and the positioning rod 2-2 is clamped at the point A to ensure that the lifting mounting bracket 3 cannot move upwards.

When the lifting mounting bracket 1 sinks, downward force is applied to the lifting mounting bracket 1, the lifting mounting bracket 1 starts to move downwards when gravity pressure is larger than the elastic force of the spring 2-1, the positioning rod 2-2 moves upwards along the chute, when the positioning rod moves to the junction with the first inclined section BC, the positioning rod 2-2 can only move to the left end to enter the first inclined section BC due to the action of the height difference of the steps (the left end is a smooth rising surface and the right end is a stop step), then the positioning rod moves to the second vertical section CD along the first inclined section BC until reaching the point D, and at the moment, the positioning rod 2-2 cannot move upwards to stop applying force due to the fact that the positioning rod 2-2 is propped against the top of the second vertical section CD.

After the positioning rod 2-2 reaches the point D, the force is stopped, the top of the lifting mounting bracket 1 is lower than the panel, under the action of the elastic force of the spring 2-1, the lifting mounting bracket 1 will rise upwards, and the positioning rod 2-2 can only advance obliquely downwards along the second inclined section DE due to the action of the step height difference at the transition part, so that the point E is the parallel part of the panel and the top of the lifting mounting bracket 3, and the pressing process is completed.

For the lifting of the lifting mounting bracket 1, the principle is the same as that of the lifting mounting bracket during pressing, the lifting mounting bracket 1 overcomes the elasticity of the spring 2-1 and the balance of the gravity of the lifting mounting bracket 1 and the tension generated by the positioning rod 2-2, so that the positioning rod 2-2 moves to the point F along the third inclined section EF, then moves to the point G and then moves to the point A, and the midway guiding mode is still the height difference at the transition position of the two sections to fix the movement direction.

In this embodiment, the first inclined section BC, the second inclined short DE and the fourth inclined section GB preferably have an angle of more than 45 ° with the horizontal line, and the third inclined section has an angle of less than 45 ° with the horizontal line.
