Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments, and the following embodiments are used for illustrating the present invention, but do not limit the scope of the present invention.
The first embodiment is as follows:
as shown in fig. 2 and 3, the utility model provides an adjusting shim with self-locking function, including gasket body 6, gasket body 6 is diameter D's round gasket, is provided with an opening 7 on gasket body 6, is inserted in opening 7 by plug-in components, and in this embodiment, as shown in fig. 1 to adjust shim between bogie air spring and the air spring mount pad for the example and explain in detail, by plug-in components for cylinder 5 of air spring gas outlet department. The adjusting gasket is not only arranged between the bogie air spring and the air spring mounting seat, but also is suitable for any other component needing to be provided with the adjusting gasket.
The opening 7 is a U-shaped opening structure formed by connecting two straight line side edges 7a and an arc edge 7b, and bulges 8 protruding towards the direction of the central line of the opening are arranged at the connecting points of two end points of the arc edge 7b and the two straight line side edges 7 a. In order to avoid damaging the cylinder 5 at the air outlet of the air spring, the bulges 8 are all subjected to smooth treatment.
In this embodiment, in order to guarantee the chucking effect, the dismouting of being convenient for again, preferably, the distance a value between the summit of two bellyings 8 is greater than or equal to the diameter of cylinder 5, be configured into little clearance fit between the two, the scope of clearance a value between the summit of two bellyings 8 and the cylinder 5 is preferably 0-0.15mm, be blocked tightly between two bellyings 8 after cylinder 5 inserts opening 7, at this moment, need certain external force just can deviate from adjusting shim 4 from cylinder 5 of gas outlet department, make adjusting shim 4 have the function of auto-lock, can effectively prevent adjusting shim 4 to drop. Meanwhile, after the cylinder 5 is inserted into the opening 7, the adjusting gasket 4 can rotate around the cylinder 5, which is beneficial to reducing the assembly difficulty.
The diameter of the circular arc edge 7b and the distance between the tail ends of the two straight line side edges 7a are both larger than the diameter of the air spring air outlet cylinder 5, so that the adjusting gasket 4 is convenient to disassemble and assemble, more preferably, the distance d between the tail ends of the two straight line side edges 7a is equal to the diameter of the circular arc edge 7b, and the value d is larger than the value a.
In this embodiment, the arc length of the arc edge 7b is greater than that of the semicircle, the two protrusions 8 are symmetrically arranged relative to the central line of the opening 7, that is, the two protrusions 8 are both arranged on one side of the central line of the arc edge 7b (perpendicular to the central line of the opening 7) facing the end of the opening 7, and the included angle between the top point of the two protrusions 8 and the circle center of the arc edge 7b is less than 180 °.
In this embodiment, in order to simplify the processing process of the adjustment pad 4 and reduce the cost, preferably, the vertex of the protrusion 8 is located on the arc line of the arc edge 7b, the end point of the arc edge 7b is the starting point of the protrusion 8 and is also the vertex of the protrusion 8, the two linear sides 7a are arranged at equal intervals from the starting point to the end, the vertex of the protrusion 8 and the starting point of the linear side 7a are transited by an arc line, as shown in fig. 3, the arc line includes two segments R1 and R2, and R1 is greater than R2.
When the opening 7 of adjusting shim 4 is plugged into cylinder 5, because of the minimum distance between two archs 8 equals the diameter of cylinder 5, there is the sensation of chucking, adjusting shim 4 can be rotatory around cylinder 5 after plugging in, simultaneously because protruding 8's existence, make adjusting shim 4 can better chucking in the cylinder 5 department of air spring gas outlet after plugging in, adjusting shim 4 needs certain external force just can deviate from cylinder 5, consequently, make adjusting shim 4 have the function of auto-lock, can guarantee that adjusting shim 4 can not drop. Meanwhile, the two side edges of the opening 7 are designed into straight side edges, and the distance is larger than the diameter of the round body 5, so that the installation and the disassembly of the adjusting gasket 4 are convenient.
In this embodiment, the side portion of the gasket body 6 further has a linear edge 9, the linear edge 9 is provided to cooperate with a tool for detaching the adjustment gasket 4, and an operator pushes the tool for detaching against the linear edge 9 to detach and mount the adjustment gasket 4. Specifically, preferably, the straight edge 9 is disposed opposite to the opening 7, the center of the straight edge 9 coincides with the center line of the opening 7, and the straight edges 9 are disposed on both sides of the gasket body 6 opposite to the opening 7, so that the tool can be pushed against the side away from the opening 7 when the adjustment gasket 4 is inserted, and the tool can be pushed against the side of the opening 7 when the adjustment gasket 4 is detached. Through the setting of straight line limit 9, not only make things convenient for operating personnel to use instrument dismouting adjusting shim 4, also be favorable to operating personnel to confirm the direction of opening 7 according to the position of straight line limit 9 simultaneously.
Example two:
as shown in fig. 4 and 5, the difference from the embodiment is that the starting points of the two straight-line sides 7a coincide with the top point of the protrusion 8, the distance from the starting point to the end of the two straight-line sides 7a is designed to be a trumpet shape with a small inside and a large outside, that is, the distance between the starting points of the two straight-line sides 7a is smaller than the distance between the end points, the two straight-line sides 7a are arranged in oblique lines, and the distance d between the end points is equal to the diameter of the circular-arc side 7 b. In this structure, the opening 7 gradually expands from the peak a of the protrusion 8 to the end d of the linear side 7a, which is more favorable for clamping the adjustment pad 4 and is more favorable for mounting and dismounting the adjustment pad 4.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and although the present invention has been disclosed with reference to the above preferred embodiment, but not to limit the present invention, any person skilled in the art can make some changes or modifications to equivalent embodiments without departing from the scope of the present invention, and any simple modification, equivalent change and modification made to the above embodiments by the technical spirit of the present invention still fall within the scope of the present invention.
