Description

1. Technical field

[0001] The invention relates to a door and window transmission handle, in particular to a transmission mechanism handle with a lubrication device. 2. Background technology

[0002] At present, all plastic-steel transmission mechanism handles on the market are not equipped with lubrication devices. During the use of the handles, especially after a long time and in harsh environments, abnormal noises, excessive operating force, and even damage may occur. In order to avoid damage to the transmission mechanism handle due to wear and better extend the service life of the handle, a transmission mechanism handle with a lubrication device is specially invented. (III) Summary of the invention

[0003] In order to make up for the deficiencies of the prior art, the present invention provides a transmission mechanism handle with a lubrication device which has a simple structure, a reasonable design and a long service life.

[0004] The present invention is achieved through the following technical solutions:

[0005] A transmission mechanism handle with a lubrication device comprises a handle seat and a handle connected by a square pin, the handle seat is provided with a handle buckle cover on one side of the handle, and is characterized in that: a lubricating oil chamber connected to the handle seat is provided on the handle, and the lubricating oil chamber is connected to the square pin hole on the handle through an oil flow channel; two steel balls are symmetrically installed in the handle seat, and the two steel balls are respectively supported by springs clamped into the handle seat, a gear sleeve for fixing the steel balls is installed in the handle seat, a countersunk hole for riveting the handle is provided on the gear sleeve, and a sealing ring is fixed in the clamping groove of the gear sleeve, and a buckle plate and a decorative buckle plate are sequentially installed on one side of the sealing ring on the inner side surface of the handle seat; the oil flow channel is connected to the oil groove on the gear sleeve.

[0006] The present invention realizes the storage of lubricating oil in the handle by setting the lubricating oil cavity in the handle, and squeezes the lubricating oil into the handle seat by pressure drop to lubricate the worn parts of the gear sleeve and the steel ball, thereby avoiding wear caused by long-term use.

[0007] A better technical solution of the present invention is:

[0008] The side grooves of the oil groove opening on the gear sleeve match the position of the steel ball, so that the lubricating oil guided out from the oil flow channel can be in contact with the gear sleeve and the steel ball.

[0009] A handle buckle cover is installed on the handle seat, and a plastic elastic pad is installed on the middle hole of the handle buckle cover. The handle extends into the handle seat through the plastic elastic pad, and is positioned and riveted with the gear sleeve through the positioning block on the handle; the handle buckle cover is fixed in position by fixing the plastic elastic pad so that it cannot be opened at will, and the positioning block and the gear sleeve are positioned to achieve riveting of the root of the handle and the gear sleeve, and the riveted part of the handle and the gear sleeve corresponds to the countersunk hole position on the gear sleeve, and the riveting is tight without gaps.

[0010] A connecting block is threadedly connected to the mouth of the lubricating oil chamber, a plastic sealing gasket is fixed to the connecting block on one side of the lubricating oil chamber, and an adjusting cap is connected to the other side through a flat-head bolt, and a hexagonal socket is arranged on the top of the adjusting cap; a decorative cover located on the outside of the connecting block is buckled on the mouth of the lubricating oil chamber; the connecting block and the plastic sealing gasket connected to the adjusting cap are threaded into the handle through the hexagonal socket on the top of the adjusting cap, and then the decorative buckle cover is covered, so that the lubricating oil chamber is in a sealed state under normal conditions.

[0011] The oil flow channel is provided with an oil nozzle connected to the lubricating oil chamber. The oil nozzle is a hole with a diameter of 0.2 mm. When the handle is rotated to 180 degrees in daily life, the oil will pass through the oil nozzle through the oil flow channel to lubricate the friction between the gear sleeve and the steel ball to avoid wear.

[0012] The present invention has a simple structure, reasonable design, and flexible application, and can effectively avoid damage to the transmission mechanism handle due to wear during use, thereby extending the service life of the device and being suitable for wide promotion and application.

[0021] The side groove of the oil groove opening 20 on the gear sleeve 15 matches the position of the steel ball 12; a handle buckle cover 11 is installed on the handle seat 10, and a plastic elastic pad 9 is installed on the middle hole of the handle buckle cover 11, and the handle 8 extends into the handle seat 10 through the plastic elastic pad 9, and is positioned and riveted with the gear sleeve 15 through the positioning block on the handle 8; a connecting block 6 is threadedly connected to the mouth of the lubricating oil chamber 1, and a plastic sealing gasket 7 is fixed to the connecting block 6 on one side of the lubricating oil chamber 1, and an adjusting cap 4 is connected to the other side through a flat head bolt 5, and a hexagonal socket is provided on the top of the adjusting cap 4; a decorative cover 3 located on the outside of the connecting block 6 is buckled on the mouth of the lubricating oil chamber 1; an oil nozzle 2 connected to the lubricating oil chamber 1 is provided on the oil flow channel 19, and the oil nozzle 2 is a hole with a diameter of 0.2 mm.

[0022] The assembly and use process of the present invention is as follows:

[0023] Put two steel balls 12 into the handle seat 10 respectively, then insert the spring 13 into the handle seat 10, cooperate with the steel ball 12 to hold the steel ball 12, put the gear sleeve 15 into the handle seat 10, make the groove in the gear sleeve 15 cooperate with the steel ball 12, put the handle buckle cover 11 (covering the installation hole of the handle seat 10 to make the overall appearance) on the handle seat 10, and then put the plastic elastic pad 9 (so that the handle buckle cover 11 cannot be opened at will) on the handle buckle cover 11, and match the handle 8 with the gear sleeve 15 (handle 8 The gear sleeve 15 is provided with a positioning block and a positioning block thereon for positioning. The gear sleeve 15 is provided with a countersunk hole 21. The handle 8 and the gear sleeve 15 are riveted together at the root of the handle 8 by a riveting machine. The countersunk hole 21 is filled with the excess riveted part. The riveted part should be firm and there should be no gap. Then the sealing ring 16 (the height is slightly higher than the height of the handle seat 10 to prevent oil from flowing out) is placed in the slot of the gear sleeve 15.
