Detailed Description
The invention is further elucidated below in conjunction with the accompanying drawings.
The directions referred to in the present specification are all directions in normal operation of the shock absorbing boom for a high-strength washing machine according to the present invention, and are not limited to directions in storage and transportation, but merely represent relative positional relationships, and not absolute positional relationships.
Examples:
as shown in fig. 1-5, the present solution provides a shock-absorbing boom for a high-strength washing machine, which comprises a supporting rod 1, wherein a clamping table 2 is installed at the top of the supporting rod 1, and the clamping table 2 is connected with a buckle at the top of the washing machine to realize fixation. A blocking seat 3 is arranged at the bottom of the supporting rod 1, a sealing cover 4 is arranged between the clamping table 2 and the blocking seat 3, the supporting rod 1 vertically penetrates through the sealing cover 4, and the sealing cover 4 is in sliding connection with the supporting rod 1; the sealing cover 4 has two functions, namely an air spring mechanism is formed by the sealing cover 4 and the blocking seat 3, and the blocking seat 3 is caused to slide in the sealing cover 4 when the supporting rod 1 moves up and down at the moment because the sealing cover and the blocking seat 3 are in sealing connection, so that the blocking seat 3 can squeeze air, and the process is similar to an air spring, so that the damping function of the supporting rod 1 is realized; and the outer wall of the sealing cover 4 is fixed with a buckle at the bottom of the washing machine, and the damping suspender is arranged between the inner cylinder and the outer cylinder of the washing machine.
In order to further optimize the shock attenuation effect, the sealed cowling 4 has set gradually the receipts platform 41 and cup joints the cover 42 from top to bottom, cup joints the bottom of cover 42 and surrounds the setting of jam seat 3, install extrusion spring 5 between receiving the platform 41 and the jam seat 3, be provided with in the receiving the platform 41 and store chamber 43, be provided with lubricating oil circuit 44 between storage chamber 43 and the bracing piece 1. The superposition buffering is realized through the extrusion spring 5 and air compression, and the damping effect is ensured to the greatest extent. In actual assembly, grease or other lubricating grease is often smeared on the outer wall of the support rod 1, however, the grease is gradually reduced during long-term use, and noise is caused. In order to solve the above problem, the top of the sealing cover 4 is provided with a storage cavity 43, then a filling oil pipeline 46 communicated with the storage cavity 43 is arranged on the side wall of the sealing cover 4, and lubricating grease is sent to the storage cavity 43 by using the filling oil pipeline 46. This design allows the lubrication grease in the reservoir 43 to be continuously replenished between the support bar 1 and the seal housing 4. Under the influence of gravity, lubricating grease can naturally flow downwards and slowly fill between the blocking seat 3 and the sealing cover 4. The design reduces the occurrence probability of noise and prolongs the service life of the damping suspender.
If the lubrication oil passage 44 is not restricted, there is a possibility that the grease in the reservoir 43 is consumed at a high rate, that is, the grease may flow outward when the washing machine is not operated. To solve this problem, the lubrication oil passage 44 includes a fixed chamber in which the lubrication ball 441 is installed, and a partial area of the lubrication ball 441 is in contact with the support rod 1. When the washing machine is not in operation, the lubrication ball 441 plays a role of blocking, and when the washing machine is in operation, the support rod 1 moves up and down, at this time, the support rod 1 drives the lubrication ball 441 to rotate, and the lubrication grease in the lubrication oil path 44 is brought out by the rotating lubrication ball 441, so that lubrication is realized.
In order to avoid oil accumulation in the storage chamber 43, one end of the lubrication oil path 44 is connected to the bottom of the storage chamber 43.
The lubricating grease flows downward under the influence of gravity, but the flow speed is low, and it is difficult to replenish the grease between the clogging seat 3 and the seal cover 4. For this purpose, the inside of the blocking seat 3 is provided with an oil storage cavity 31, an oil outlet channel 32 is arranged between the oil storage cavity 31 and the sleeve cover 42, one end of the oil outlet channel 32 is communicated with the sleeve cover 42, and the other end of the oil outlet channel 32 is communicated with the bottom of the oil storage cavity 31. The design enables lubricating grease to be continuously supplemented between the sealing cover and the sealing seat along with the sliding of the sealing seat 3 in the sealing cover 4, and the sufficient lubrication between the sealing cover and the sealing seat is ensured.
The oil outlet channel 32 includes a limiting cavity, in which the blocking ball 33 is installed, and a partial area of the blocking ball 33 contacts with the socket cover 42, which is the same as the principle of the lubrication ball 441.
In order to further ensure air tightness, a positioning groove 34 is arranged in the circumferential direction of the blocking seat 3, and an elastic protrusion 47 matched with the positioning groove 34 is arranged on the inner wall of the sleeve cover 42.
The elastic protrusion 47 plays a role of enhancing air tightness, but itself continuously passes through one end of the oil outlet passage 32 along with the sliding of the clogging seat 3, and is contaminated with the lubricating grease, so that the check ball 33 can be omitted by utilizing this characteristic. Thus, the positioning groove 34 is located between the oil outlet channel 32 and the clamping table 2, and/or the positioning groove 34 is located on the side of the oil outlet channel 32 away from the clamping table 2.
Preferably, the blocking seat 3 is made of corrosion-resistant elastic rubber, and an air bag 35 is arranged at the bottom of the blocking seat 3.
In order to prevent the clamping table 2 from separating from the supporting rod 1, one end of the supporting rod, which is far away from the blocking seat 3, is provided with a fixing table 11, and a sealing gasket 12 is arranged between the fixing table 11 and the clamping table 2. The gasket 12 is made of elastic material, so as to avoid the problem of breakage of the clamping table 2 caused by hard contact between the clamping table 2 and the fixing table 11.
In order to reduce the water drop corrosion support bar 1 thrown out of the inner barrel of the washing machine, the top of the clamping table 2 is provided with a sealing cover 6, the clamping table 2 comprises a first cavity 21 and a second cavity 22, and the support bar 1 penetrates through the first cavity 21 to be connected with the fixing table 11. The first cavity 21 in this scheme is used for fixed station 11, and the effect of second cavity 22 then is the drop of water that throws away in the interception inner tube, avoids drop of water and bracing piece 1 direct contact, leads to bracing piece 1 to receive the corruption.
In summary, the scheme has the following advantages: firstly, utilize the storage chamber 43 to store lubricating grease to with lubricating grease through lubricating oil circuit 44 constantly supply between sealed cowling 4 and the bracing piece 1, realized sealed, lubrication, anticorrosion, noise reduction and extension whole life's purpose. Secondly, by utilizing the lubricating balls 441, lubricating grease can be continuously supplemented between the sealing cover 4 and the supporting rod 1 when the washing machine works, and the lubricating grease is sealed when the washing machine does not work, so that the waste of the lubricating grease is reduced.
The present invention is not limited to the above-described specific embodiments, and various modifications may be made by those skilled in the art without inventive effort from the above-described concepts, and are within the scope of the present invention.
