Specific embodiment
The utility model discloses a kind of sliding sleeve groups, which can be avoided the abrasion of bolt and slideway, to improve
The service life of main brace device.
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are in the premise for not making creative work
Under all other embodiment obtained, fall within the protection scope of the utility model.
In a specific embodiment of the present invention, sliding sleeve group includes inner sliding sleeve 12 and outer sliding sleeve 11.Inner sliding sleeve 12 and outer
Sliding sleeve 11 is cylindrical shape.Bolt 4 can be threaded through in inner sliding sleeve 12.Outer sliding sleeve 11 is sleeved on outside inner sliding sleeve 12, and can cross around
Inner sliding sleeve 12 rotate.The length of outer sliding sleeve 11 and inner sliding sleeve 12 is all larger than the thickness of chute board 2, in other words the both ends of sliding sleeve group
It is protruded respectively in the two sides of chute board 2.In addition, outer sliding sleeve 11 can be threaded through in the slideway 21 of chute board 2, and can be along cunning
Road 21 rolls.
Main brace device includes main corbel, spring, mounting rack 3, chute board 2, bolt 4, nut 5.Chute board 2 has arc
Slideway 21.One end of spring is connected on main corbel, and the other end is connected on mounting rack 3.There are two opposite peaces for the tool of mounting rack 3
Loading board 31.4 hole of bolt is provided on mounting plate 31.During installation, two mounting plates 31 is made to be located at the two of chute board 2
Sliding sleeve group in the utility model is threaded through in slideway 21 by side, and bolt 4 is made to sequentially pass through the bolt 4 on a mounting plate 31
Hole, inner sliding sleeve 12,4 hole of bolt on another mounting plate 31, and lock nut 5 by bolt 4.Main brace device is in holding state
And bounce when switching between state, bolt 4 can be moved to the other end from one end of slideway 21, at the same spring can realize it is flexible.Spiral shell
The specific move mode of bolt 4 is: bolt 4 drives the sliding of inner sliding sleeve 12 or rolls, and inner sliding sleeve 12 drives outer sliding sleeve 11 to roll.Separately
Outside, during installation, the locking torque of bolt 4 is controlled, so that outer sliding sleeve 11 can be rotated relative to inner sliding sleeve 12
Subject to.So that inner sliding sleeve 12 can be rotated relative to bolt 4, and it is best that outer sliding sleeve 11 can be rotated relative to inner sliding sleeve 12.
This embodiment avoids the sliding frictions between bolt 4 and slideway 21, but by outer sliding sleeve 11 along slideway 21
Rolling realize the movement of bolt 4, therefore this embodiment avoids the abrasions of bolt 4, improve the service life of bolt 4.
In addition, outer sliding sleeve 11 rolls and non-slip in slideway 21, therefore smooth degree with higher.
Further, by the length for being longer than outer sliding sleeve 11 of the Design of length of inner sliding sleeve 12, the i.e. both ends of inner sliding sleeve 12 point
The both ends of outer sliding sleeve 11 are not protruded from.In this way, in clamping screw 4, as long as mounting plate 31 is pressed on the end face of inner sliding sleeve 12
Just explanation is installed in place, to greatly simplifie installation difficulty.In this embodiment, bolt 4 and the locking of inner sliding sleeve 12 are one
Body, for main brace device when holding state and bouncing switches between state, bolt 4 and inner sliding sleeve 12 can drive outer sliding sleeve 11 along cunning
Road 21 rolls.Specifically, the length of inner sliding sleeve 12 is 0.5-1mm longer than the length of outer sliding sleeve 11, can so ensure outer sliding sleeve 11
Always it is contacted with slideway 21.Certainly, if considering that the locking torque of bolt 4 still can with inner sliding sleeve 12 based on optimum state
It is rotated relative to bolt 4, it is best that outer sliding sleeve 11 can be rotated relative to inner sliding sleeve 12.
In a specific embodiment of the present invention, the hardness for limiting inner sliding sleeve 12 is less than the hardness of bolt 4.In this way,
When occurring between bolt 4 and inner sliding sleeve 12 relative to sliding or rotation, inner sliding sleeve 12 can be worn, and bolt 4 will not be worn,
Bolt 4 is just so protected, prevents bolt 4 from fracture occurs suddenly and occurs dangerous.
It specifically, is preferably copper by the material of inner sliding sleeve 12.Material by outer sliding sleeve 11 is preferably steel.Copper inner sliding sleeve
12 quality is soft, and when the bolt 4 with steel is worn, copper sliding sleeve is abrasion side.The price of the outer sliding sleeve 11 of steel is lower
It is honest and clean, to reduce the cost of sliding sleeve group.
The utility model additionally provides a kind of main brace device, which includes bolt 4, nut 5, chute board 2, bullet
Spring, mounting rack 3, sliding sleeve group.Chute board 2 has slideway 21, and one end of spring is connected on vehicle frame 6, and the other end is connected to installation
On frame 3, mounting rack 3 has two opposite mounting plates 31, and two mounting plates 31 are located at the two sides of chute board 2, and sliding sleeve group is in cunning
On road 21, bolt 4 is threaded through in sliding sleeve group and two mounting plates 31.Nut 5 is threadedly engaged with bolt 4, and bolt 4 is locked.
Sliding sleeve group in the present embodiment is any one of the above sliding sleeve group, and above-mentioned sliding sleeve group has said effect, has above-mentioned sliding sleeve group
Main brace device equally there is said effect, therefore, this article will not repeat them here.
Further, nut 5 loosens during use in order to prevent, nut 5 can be welded on mounting plate
On 31, during installation, directly bolt 4 is inserted into 4 hole of bolt and sliding sleeve group of two mounting plates 31, and simultaneously
It is screwed in nut 5.In addition, nut 5 belongs to small part, nut 5 is welded on mounting plate 31, also avoids installing
During nut 5 loss.
