Description

One kind can self-oiling spring

Technical field

The utility model relates to mechanical engineering fields more particularly to one kind can self-oiling spring.

Background technique

Spring is a kind of using the elastic machine components come work, is generally made of spring steel, to control the fortune of parts It is dynamic, mitigate impact or vibration, storage or saving energy, the size of measuring force etc., machine is widely used in, in instrument, since spring is certain After working environment or long-time use, need to oil to spring and other parts, therefore it provides a kind of structure it is simple, It is easily achieved, the spring with automatically oiling function is very necessary.

Utility model content

In order to overcome the defects of the prior art described above, the technical problem to be solved by the utility model is to provide a kind of structures Simply, it is easily achieved, it can self-oiling spring.

In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model are as follows: one kind can self-oiling spring, Including spring body, the inside of the spring body is hollow structure, and the channel inside the spring body is used for oil storage, described The opening along the distribution of spring spiral outer wall is offered on spring body, the opening is connected to the channel.

In an alternative embodiment, it is described can self-oiling spring further include oil storage rope, the oil storage rope is contained in described In channel.

In an alternative embodiment, the material of the oil storage rope is the rope made of hemp or cotton cord.

In an alternative embodiment, the position that the spring body is located at the opening offers through slot, and the one of the through slot End is connect with the channel, the other end and external connection of the through slot.

In an alternative embodiment, it is described can self-oiling spring further include closeouts, the closeouts are arranged in spring It the both ends of main body and is adapted with the channel.

In an alternative embodiment, projection of shape of the opening in the plane perpendicular to spring rotating path is sector.

The utility model has the beneficial effects that: a kind of spring is provided, the inner hollow and both ends open of the spring body, Opening is opened up by the inner surface in spring body, makes inner cavity and the turned on outside of spring body, when spring body is pressed After compeling, the oil in inner cavity can be overflowed from opening, to realize the automatically oiling to spring and other parts, the utility model Structure is simple, is easily achieved, and saves a large amount of manpower and extends the service life of spring and other parts.

Specific embodiment

For technology contents, the objects and the effects that the utility model is described in detail, below in conjunction with embodiment and match Attached drawing is closed to be explained.

The design of the utility model most critical is: opening up opening by the inner surface in spring body, makes spring master The inner cavity of body and turned on outside.

Please refer to shown in Fig. 1 to Fig. 2, one kind of the utility model can self-oiling spring, including spring body is described The inside of spring body is hollow structure, and the channel inside the spring body is used for oil storage, is offered on the spring body Along the opening of spring spiral outer wall distribution, the opening is connected to the channel.

As can be seen from the above description, the utility model has the beneficial effects that: in use, after spring body is oppressed, Oil in inner cavity can be overflowed from opening, to realize the automatically oiling to spring and other parts.Oil itself has certain Viscosity, according to this characteristic adjustment opening size can guarantee spring only when compressive deformation to a certain degree when can just go out Oil, spring are generally formed by spring steel helically coiling, and above-mentioned opening is in bar shaped, the side wall of spring steel are provided with, in this way in spring It can guarantee that opening rotating path is consistent with spring when rotational forming.

Further, it is described can self-oiling spring further include oil storage rope, the oil storage rope is contained in the channel.

As can be seen from the above description, by the inner cavity of spring place oil storage rope, further ensure spring only when by Compressive strain to a certain degree when, oil storage rope can just be oppressed it is fuel-displaced, it is structurally reasonable and be conveniently replaceable.

Further, the material of the oil storage rope is the rope made of hemp or cotton cord.

As can be seen from the above description, the rope made of hemp or cotton cord have good oil storage effect.

Further, the position that the spring body is located at the opening offers through slot, one end of the through slot and institute State channel connection, the other end and external connection of the through slot.

As can be seen from the above description, the design of through slot improves oil yield efficiency, ensure that oil uniformly, enhance the effect that oils Fruit.

Further, it is described can self-oiling spring further include closeouts, spring body is arranged in the closeouts It both ends and is adapted with the channel.

As can be seen from the above description, closeouts guarantee that oil will not be flowed out from spring body both ends open.

Further, projection of shape of the opening in the plane perpendicular to spring rotating path is sector.

As can be seen from the above description, the opening section of opening is designed to sector, in this way may be used since oil has certain stickiness To reduce oil when overflowing and the contact area of aperture position, convenient for spring body compressive deformation and storage is squeezed in the lumen Oil.

Please refer to shown in Fig. 1 to Fig. 2, the embodiments of the present invention one are as follows: one kind can self-oiling spring, including bullet Spring main body 1, the inside of the spring body 1 are hollow structure, and the channel 2 inside the spring body 1 is used for oil storage, the bullet The opening 3 along the distribution of spring spiral outer wall is offered in spring main body 1, the opening 3 is connected to the channel 2.

Please refer to shown in Fig. 1 to Fig. 2, the embodiments of the present invention two are as follows: one kind can self-oiling spring, including bullet Spring main body 1, the inside of the spring body 1 are hollow structure, and the channel 2 inside the spring body 1 is used for oil storage, the bullet The opening 3 along the distribution of spring spiral outer wall is offered in spring main body 1, the opening 3 is connected to the channel 2.

It is described can self-oiling spring further include oil storage rope 4, the oil storage rope 4 is contained in the channel 2.The storage The material of wick 4 is the rope made of hemp or cotton cord.The position that the spring body 1 is located at the opening 3 offers through slot 5, the through slot 5 One end connect with the channel 2, the other end and external connection of the through slot 5.It is described can self-oiling spring further include Closeouts 6, the closeouts 6 are arranged in the both ends of spring body 1 and are adapted with the channel 2.

In conclusion a kind of spring provided by the utility model, the inner hollow and both ends open of the spring body, pass through Opening is opened up in the inner surface of spring body, makes inner cavity and the turned on outside of spring body, after spring body is oppressed, Oil in inner cavity can be overflowed from opening, to realize the automatically oiling to spring and other parts, the utility model structure Simply, it is easily achieved, saves a large amount of manpower and extends the service life of spring and other parts.

The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all Equivalents made based on the specification and figures of the utility model are applied directly or indirectly in relevant technology neck Domain is also included in the patent protection scope of the utility model.
