[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0028] The present invention will be further described below with reference to the embodiments.
[0029] This embodiment provides a buffer structure for a mechanically locked integrated valve pushrod, such as... Figures 1 to 5 As shown, it includes a valve push rod body 1, a bare head body 2 fixedly connected to the bottom end of the valve push rod body 1, and a multi-layer processing mechanism provided on the outer surface of the valve push rod body 1.
[0030] The multi-layer processing mechanism is used to buffer the end of the valve push rod body 1 away from the bald head body 2, and to lubricate the connection between the valve push rod body 1 and the rocker arm ball joint during the buffering process.
[0031] As a preferred embodiment of this example, Figure 3 , Figure 4 and Figure 5As shown, the multi-layer processing mechanism includes a buffer ring 31, which is threaded to the outer surface of the valve push rod body 1. A mounting plate 32 is fixedly connected to the outer surface of the buffer ring 31. A reservoir 33 is fixedly connected to the top of the mounting plate 32. An integrated sealing plug is inserted into the top of the reservoir 33. A guide tube 34 is fixedly connected to the side of the reservoir 33 near the buffer ring 31. An atomizing plate 35 is fixedly connected inside the guide tube 34. A processing chamber is opened inside the buffer ring 31 and is connected to the guide tube 34. A processing hole 38 is opened at the top of the buffer ring 31 and is connected to the processing chamber. Multiple conical buffer blocks 36 and hemispherical buffer blocks 37 are fixedly connected to the top of the buffer ring 31. The hemispherical buffer blocks 37 are disposed between every two conical buffer blocks 36.
[0032] Working principle:
[0033] Initial limitations:
[0034] Before using this utility model, the user needs to install a micro-transfer pump inside the storage tank 33 and connect the outlet of the micro-transfer pump to the delivery tube 34. The user needs to manually pull the integrated sealing plug at the top of the storage tank 33 upwards to move the integrated sealing plug away from the top of the storage tank 33. When the integrated sealing plug is completely detached from the top of the storage tank 33, the user needs to inject lubricant into the storage tank 33 from the connection between the integrated sealing plug and the storage tank 33. After the lubricant is injected, the integrated sealing plug is reinserted into the top of the storage tank 33.
[0035] like Figures 1 to 5 As shown, by installing the conical buffer block 36 and the hemispherical buffer block 37 on the top of the buffer ring 31, the force borne by the valve push rod body 1 is buffered by the conical buffer block 36 and the hemispherical buffer block 37 when the valve push rod body 1 is in use. The unique shape of the hemispherical buffer block 37 distributes the external pressure evenly along the spherical surface, making the force at each point more uniform, which is conducive to providing a greater buffering effect. In addition, the shape of the conical buffer block 36 can maintain its shape and function when the valve push rod body 1 is impacted, providing a reliable buffering effect, thereby ensuring the normal performance of the valve push rod body 1 during use.
[0036] The user turns on the power supply of the micro conveying pump, so that the micro conveying pump starts to work, the micro conveying pump conveys the lubricant in the storage tank 33 to the inside of the lubricant guide pipe 34, then the lubricant is atomized by the atomizing plate 35 in the inside of the lubricant guide pipe 34, the lubricant mist is guided from the inside of the lubricant guide pipe 34 to the processing cavity in the buffer ring 31, then is guided out from the processing hole 38 to the joint between the valve push rod body 1 and the rocker arm ball head, and then lubricates the joint between the valve push rod body 1 and the rocker arm ball head, which is beneficial to reduce the friction of the joint between the valve push rod body 1 and the rocker arm ball head, and then improve the buffering effect of the conical buffer block 36 and the hemispherical buffer block 37, and the mist lubrication is adopted, which is beneficial to the lubricant covering the joint between the valve push rod body 1 and the rocker arm ball head, and then improves the lubrication effect of the joint between the valve push rod body 1 and the rocker arm ball head.
[0037] The above examples are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
