BRIEF DESCRIPTION OF THE DRAWINGS
[0012] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art are briefly introduced below.
[0013] Figure 1 It is a schematic diagram of the utility model.
[0014] Figure 2 It is a schematic diagram of the assembly of the connecting seat and the airbag. DETAILED DESCRIPTION
[0015] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings. The above description is simplified for the convenience of describing the present invention, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.
[0016] The singular forms "a", "said" and "the" used in the specification include plural forms unless clearly indicated. The terms "include", "comprise" and "contain" used in the specification indicate the presence of the claimed features, but do not exclude the presence of one or more other features. The term "and / or" used in the specification includes any and all combinations of one or more of the relevant listed items.
[0017] In the specification, when an element is said to be "on", "fixed" to, "connected" to, "engaged" to, etc., another element, the element may be directly on, fixed to, connected to, engaged to, or in contact with the other element, or there may be intervening elements. In the specification, when a feature is arranged "adjacent" to another feature, it may mean that the feature has a portion overlapping with the adjacent feature or a portion located above or below the adjacent feature.
[0018] It is to be understood that although the terms "first", "second", etc. may be used herein to describe different elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. Therefore, a first element may be referred to as a second element without departing from the teachings of the present application.
[0019] The following will describe exemplary embodiments of the present application with reference to the accompanying drawings. However, it should be understood that the present application can be presented in a variety of different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments. In all drawings, the same reference numerals represent the same or functionally identical elements.
[0020] Figure 1 The structure of the test bench connecting seat is composed of an upper connecting seat 10 and a lower connecting seat 20. A first airbag through hole 12, a second airbag through hole 13 and a third airbag through hole 14 are respectively provided on the pressure plate 11 of the upper connecting seat 10. The first airbag through hole 12, the second airbag through hole 13 and the third airbag through hole 14 are arranged in a straight line, and the virtual connecting line therebetween passes through the axis point of the upper connecting seat 10. A bracket 15 is provided on the pressure plate 11 to form a cavity 18 above the first airbag through hole 12, the second airbag through hole 13 and the third airbag through hole 14. The second boss 16 extends upward from the top of the bracket 15, and a cross bar 17 connected to the pressurized cylinder of the test bench is provided on the side of the second boss 16.
[0021] A positioning hole 22 is provided in the center of the lower connecting seat 20, and a first boss 23 for connecting to the test bench base extends downward from the bottom thereof. Specifically, a pin hole 24 is provided transversely through the side of the first boss 23. The first boss 23 is coaxial with the positioning hole 22, and the joint surface between the lower connecting seat 20 and the airbag 1 is a plane, so that the lower connecting seat 20 remains stable during the loading process of the airbag 1.
[0022] Combined with reference Figure 2 The assembly display shows that a threaded connector is provided at the bottom of the airbag 1 and is fastened to the positioning hole 22 on the lower connecting seat 20, so that the plane part of the lower connecting seat 20 is close to the bottom of the airbag 1. The top of the airbag 1 has an inflation hole 2 and a deflation hole 3 for inflation and deflation, which pass through two of the first airbag through hole 12, the second airbag through hole 13 and the third airbag through hole 14 respectively. By providing a plurality of through holes with different apertures on the upper connecting seat 10, one connecting seat can match airbags of various models. After the upper and lower connecting seats 10, 20 are connected to the airbag 1, a pin is used to pass through the pin hole 24 to fix the lower connecting seat 10 on the stand base, and the upper connecting seat 10 is fixed by clamping the cross bar 17 with the card slot on the pressurized cylinder.
