Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a cross-sectional view of the weighing assembly.
The labels in the figures are: 1-a mounting seat, 2-a weighing component, 3-a telescopic frame, 4-a weighing sensor, 5-a first sleeve, 6-a connecting shaft, 7-a pressure spring, 101-a vertical plate, 102-a second sleeve, 103-a first rib plate and 104-a second rib plate.
Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. A weighing device for an elevator car is shown in figure 1 and comprises a mounting seat 1, wherein weighing components 2 which are symmetrically arranged are connected to two sides of the mounting seat 1; weighing component 2 includes expansion bracket 3, and the middle part of expansion bracket 3 is connected with weighing sensor 4, and weighing sensor 4 can select for use the button type micro-gap switch of morals and western electric company, and the transmission button of 4 upper ends of weighing sensor extends to expansion bracket 3 top, is equipped with first sleeve 5 on the expansion bracket 3 of 4 both sides of weighing sensor, and 5 inboards of first sleeve are equipped with connecting axle 6, and the outside of connecting axle 6 is equipped with the pressure spring 7 that is located first sleeve 5.
The two ends of the connecting shaft 6 are respectively connected with a limiting part positioned on the outer sides of the mounting base 1 and the telescopic frame 3, and the limiting part can be the head of a nut or a bolt.
The first sleeve 5 is sleeved on the outer side of the second sleeve 102, and the lower end of the pressure spring 7 is attached to the top of the second sleeve 102.
A plurality of first rib plates 103 connected with the mounting base 1 are arranged on one side of the vertical plate 101, which is far away from the weighing component 2, and a plurality of second rib plates 104 are connected between the second sleeve 102 and the vertical plate 101.
