Abstract
The balance rod for washing machine cylinder consists of support rod and rod body. It features that inside the sleeve, there is one polyurethane rubber block capable of forming sliding friction with the inner wall of the sleeve and with spring seat for supporting spring embedded in the center. The upper and lower support rods connected to the washing machine cylinder and the base are connected to the two ends of the spring seat. The utility model discloses can attenuate the vibrational force, the swinging force of washing machine cylinder body at to a great extent, furthest gives the ability that washing machine cylinder body fast balance is stable. Use the utility model discloses can reduce washing machine cost, noise reduction, improve operational reliability, prolong its life.
Description
The utility model relates to damping device.More more particularly, be a kind of being used in the washing machine, so that washing machine when work, cylinder body keeps the washing machine cylinder body haltere of balance.
In the prior art, no matter be full-automatic or semi-automatic washing machine, all be directly to adopt metal spring that the washing machine cylinder body is carried out damping, damping metal spring one end is fixed in the washing machine cylinder body, and the other end is fixed in casing of washing machine.There is following obvious weak point in such shock-damping structure.
1, because the elasticity of metal spring own is limit, its balance and stability performance is relatively poor, especially when the washing machine initialization.
2, because metal spring is connected with casing of washing machine, the intensity, thickness that must increase casing is keeping firmly, thereby the increase cost.
The vibration that produces when 3, washing machine is worked is directly passed to the various electronic components that are installed on the casing, is easy to produce fault, reduces functional reliability.
4, metal spring is easy to fatigue damage under strong stress effect, and therefore be restricted service life.
The purpose of this utility model is to avoid the deficiencies in the prior art part, and the washing machine cylinder body haltere of a kind of simple in structure, long service life, good damping effect is provided.
The purpose of this utility model is realized by following technical scheme.
The utility model is made of pole and barred body.Feature of the present utility model is that described barred body is made of sleeve and the upper cover that is fixed on the sleeve upper/lower terminal, following capping, the polyurethane rubber piece that can form sliding friction with sleeve lining is housed in the sleeve, polyurethane rubber piece central authorities bury spring groove underground, and spring groove is embedded in spring.Be connected upper rack posts and the lower fulcrum bar that is connected on the washing machine base on the washing machine cylinder body described pole comprising, upper and lower pole is passed upper and lower capping respectively and is fixed on the spring groove two ends.
When the upper rack posts that is connected on the washing machine cylinder body bears certain load, owing to the good resistance against compression of polyurethane, and the humidification of metal spring, can guarantee that haltere still has less changes in amplitude under bigger load.When load alleviated, the frictional force on polyurethane rubber piece and the sleeve lining can be slowed down bounce to a great extent, and the polyurethane excellent abrasive can be guaranteed the long-term effectiveness of this frictional resistance.
The utility model is compared prior art and is had following advantage:
1, the utility model utilizes the good damping characteristic that polyurethane has, the vibration force, the nosing force that produce in the time of can decaying the washing machine cylinder body running to a great extent, thereby the ability of giving the quick balance and stability of washing machine cylinder body to greatest extent.
2, because casing itself is not subjected to stress, thereby can reduces its thickness, reduce cost, the electronic devices and components functional reliability that is installed on the casing of washing machine is improved.
3, the utility model can prolong service life greatly.
4, use the utility model can reduce the washing machine noise, thereby better people's living environment.
Accompanying drawing is the utility model structural representation.
Number in the figure:
1, upper rack posts, 2, the upper rack posts dowel hole, 3, upper cover, 4, sleeve, 5, lock nut, 6, envelope shelves ring, 7, spring groove, 8, spring, 9, the polyurethane rubber piece, 10, spring groove, 11, envelope shelves ring, 12, lock nut, 13, down capping, 14, lock nut, 15, the lower fulcrum bar dowel hole, 16, lower fulcrum bar, 17, groove.
By the following examples, in conjunction with the accompanying drawings the utility model is further described.
Embodiment:
Referring to accompanying drawing: the upper end of upper rack posts (1) is connected with the washing machine cylinder body by upper rack posts dowel hole (2), the lower end of upper rack posts (1) is passed upper cover (3) and is threaded with spring groove (7), and be equipped with envelope shelves rings (6), it is fixing to add locking nut (5).Metal spring (8) embeds spring groove (7,10), and imbeds polyurethane rubber piece (9) central authorities.Polyurethane rubber piece (9) can form sliding friction with sleeve (4) inwall.Be to offer some grooves (17) along its circumference on the periphery of the polyurethane rubber piece (9) that sleeve (4) inwall is close to.The upper end of lower fulcrum bar (16) is threaded with spring groove (10), and is equipped with envelope shelves rings (11), and it is fixing to add locking nut (12).Capping (13) is passed down in the lower end of lower fulcrum bar (16), behind lock nut (14) location, is connected with washing machine base by lower fulcrum bar dowel hole (15).Upper cover (3) and following capping (13) respectively with sleeve (4) to be threaded.
Claims (3)
1, a kind of washing machine cylinder body haltere, constitute by pole and barred body, it is characterized in that: described barred body is by sleeve (4) and be fixed on the upper cover (3) of sleeve (4) upper/lower terminal, capping (13) constitutes down, the interior dress of sleeve (4) can form the polyurethane rubber piece (9) of sliding friction with sleeve (4) inwall, polyurethane rubber piece (9) central authorities bury spring groove (7,10) underground, and spring groove (7,10) is embedded in spring (8); Be connected the upper rack posts (1) on the washing machine cylinder body described pole comprising and be connected lower fulcrum bar (16) on the washing machine base, described upper rack posts (1) and lower fulcrum bar (16) pass upper cover (3) respectively, capping (13) is fixed on spring groove (7,10) two ends down.
