[0013] In order to more clearly illustrate the technical solutions of the embodiments of the utility model, the drawings required for describing the embodiments are briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0019] See also Figure 1-3 As shown, the utility model is a rubber sealing ring size detection device, comprising a bottom plate 15, the upper surface of the bottom plate 15 is connected to a support plate 10 through five guide sleeves 14, a truncated cone-shaped column 1 is fixed to the upper surface of the support plate 10, the circumferential side wall of the truncated cone-shaped column 1 is provided with two mutually connected rectangular openings 11, and a "cross" 12 movable along the axial direction of the truncated cone-shaped column 1 is provided in the rectangular opening 11; the bottom end of the "cross" 12 is connected to five guide rods 13 inserted into the guide sleeves 14, one of which is connected to the guide sleeve 14. The outer wall of 14 is provided with a scale line B141 along the vertical direction. When in use, the rubber sealing ring is put in from the top of the truncated cone column 1 and controlled to abut against the upper surface of the "cross" 12. The inner ring of the rubber sealing ring is controlled to abut against the outer wall of the truncated cone column 1 under the action of its own gravity. At this time, the relative movable distance of the "cross" 12 to the top is passed through, that is, the scale value corresponding to the bottom end of the guide rod 13 at this time, and the inner diameter of the rubber sealing ring is calculated in combination with the radius and height of the two ends of the truncated cone column 1.

[0020] In order to ensure that any size of rubber sealing ring can be pressed against the outer wall of the truncated cone column 1 under the action of gravity after being placed in it, a piston 131 is provided at the end of the guide rod 13, which is sealed and slides along the inner wall of the guide sleeve 14, and a flow channel connected to the five guide sleeves 14 is provided in the bottom plate 15. An air inlet connected to the flow channel is provided on the upper surface of the bottom plate 15, and a plug body 151 is provided at the air inlet. Then, when in use, the position of the piston 131 in the guide sleeve 14 is adjusted according to the size of the rubber sealing ring in the initial stage; when the rubber sealing ring is larger, the piston 131 is controlled to move downward along the guide sleeve 14 and then the plug body 151 is inserted into the air inlet. At this time, the adjustment makes it possible for the rubber sealing ring to overcome the air pressure in the guide sleeve 14 and move downward as a whole after being placed in the "cross" 12.

[0021] The four ends of the cross 12 are provided with upwardly protruding bumps 121. The setting of the bumps 121 facilitates the position restriction of the placed rubber sealing ring to prevent the rubber sealing ring from sticking out from one end of the cross 12. A scale line A122 is provided along the vertical direction on one side of the bump 121. The setting of the scale line A122 facilitates the detection of the thickness of the rubber sealing ring when the rubber sealing ring is placed on the cross 12.
