Detailed Description
The invention is further described below with reference to the accompanying drawings.
The invention is composed of an L-shaped shaft body 1 and the like, wherein the horizontal section of the L-shaped shaft body 1 is rotationally connected with a fixing clamp of a sun shield, a lubricating hole 11 is arranged in the middle of a corner of the shaft body 1 along the axial direction of the horizontal section of the shaft body 1, and a push rod 12 is arranged in the lubricating hole 11, as shown in fig. 1 and 2.
The outer side face of the horizontal section of the shaft body 1 is provided with a wavy groove 21 with a groove width of 3mm and a groove depth of 2mm along the position of the axial corresponding fixing clamp, the wavy groove 21 comprises two wave crests and two wave troughs, and the arc distance between every two adjacent wave crests and wave troughs is 3mm.
A through hole 22 with a diameter of 5mm is provided in the groove 21, and the through hole 22 communicates with the lubrication hole 11 at a position where the through hole 22 is located adjacent to the non-corner end of the groove 21 corresponding to the horizontal section of the shaft body 1.
A pressure compensating hole 13 is further formed in one side of the lubricating hole 11, the pressure compensating hole 13 is arranged in parallel with the lubricating hole 11 along the axial direction of the horizontal section of the shaft body 1, the pressure compensating hole 13 is communicated with the groove 21, and the bottom of the pressure compensating hole 13 is flush with the bottom of the groove 21; the position of the pressure compensating hole 13 corresponding to the hole opening of the outer side of the shaft body 1 is provided with a receiving block 14, the receiving block 14 is provided with a first U-shaped groove 141 and a second U-shaped groove 142 which are in a step shape, the first U-shaped groove 141 is clamped on the outer side wall of the horizontal section of the shaft body 1, the second U-shaped groove 142 is positioned under the hole opening of the pressure compensating hole 13, and the hole opening of the pressure compensating hole 13 is in threaded connection with a hole cover 131.
The application method of the invention is as follows:
as shown in fig. 1 and 2, the through hole 22 is a hole inner hole, and to achieve the machining and forming of the through hole 22, the size needs to be calculated in design, and according to the design size, a hole is drilled from one side of the lubrication hole 11 to the groove 21 at a corresponding position on the horizontal section of the shaft body 1, and after the hole is drilled into the groove 21, the through hole (a position above the through hole 22 in fig. 1) at a non-use position is sealed so as to achieve a structure that the lubrication hole 11 is only in unidirectional communication with the through hole 22.
When no abnormal sound is found, the push rod 12 is inserted into the lubrication hole 11, the hole cover 131 is fixedly connected to the orifice of the pressure supplementing hole 13 in a threaded manner, the gap between the clamping surface of the sun shield fixing clamp and the outer side wall of the rotating shaft is small, the lubrication hole 11 and the groove 21 are blocked by the lubricant, and the push rod 12 cannot easily fall down; if not filled with lubricant, the push rod 12 may be removed and placed.
When the abnormal friction sound is found, solid lubricant is filled into the lubrication hole 11, the push rod 12 extrudes the lubricant into the wavy groove 21 through the through hole 22, the gap between the clamping surface of the sun shield fixing clamp and the outer side wall of the rotating shaft is smaller in the pushing process, the lubricant coming out of the through hole 22 is blocked on the clamping surface of the fixing clamp and enters the groove 21, the lubricant moves along the wavy groove 21, the rough position of the lubricant entering the groove can be known according to the pushing depth of the push rod 12, at the moment, the sun shield is rotated, the push rod 12 is continuously pushed, so that whether the abnormal friction sound between the sun shield and the rotating shaft is reduced or not is observed, if the abnormal friction sound is not changed, the push rod 12 is continuously pushed, the lubricant gradually fills the groove 21, the sun shield is continuously rotated, the lubricant moves back and forth along the groove 21 at the clamping surface of the fixing clamp, namely, the lubricant is brushed back and forth along the axial wavy groove 21, a curved surface is formed by rotating until the abnormal friction sound is eliminated.
Under the pushing of the push rod 12, the injected lubricant overflows the groove 21, and overflowed lubricant flows out through the pressure compensating hole 13, at this time, the first U-shaped groove 141 is clamped and fixed on the shaft body 1 by the connector block 14 at the orifice of the pressure compensating hole 13, and the second U-shaped groove 142 is positioned right below the orifice of the pressure compensating hole 13, so that the lubricant flowing out is temporarily collected, on one hand, the lubricant is prevented from directly dripping on the vehicle bottom plate, and on the other hand, the lubricant is also convenient to gather, so that the lubricant is collected and refilled into the lubricating hole 11 for repeated use.
After the use, take down the thing piece 14 and clean with the rag, the spiro union is gone up handhole door 131 again, and push rod 12 then is placed in lubricated downthehole 11 temporarily, and when using again, only need open handhole door 131, according to above-mentioned step repeated implementation can, simple structure is compact, lubricated effectual.
Because the position of the sun shield clamping rotating shaft is generally an opening-shaped clip, the opening angle is smaller than 180 degrees, and the maximum rotating angle of the sun shield during use is 180 degrees, when the sun shield is installed, the wave crest and the wave trough positions of the wavy grooves 21 are all arranged in the clamping surface of the clip, namely, the through holes 22 and the pressure supplementing holes 13 are respectively communicated with the grooves 21, and all arranged in the clamping surface of the clip, so that lubricant cannot overflow and pollute the sun shield at normal temperature under normal use conditions.
The undescribed portions of the invention are consistent with the prior art and are not described in detail herein.
The foregoing is only the embodiments of the present invention, and therefore, the patent scope of the invention is not limited thereto, and all equivalent structures made by the description of the invention and the accompanying drawings are directly or indirectly applied to other related technical fields, which are all within the scope of the invention.
