Description
Technical field
The utility model relates to ball-head tension rod technical fields, particularly, are related to a kind of ball-head tension rod retaining mechanism.
Background technique
Existing ball-head tension rod structure, its structure are combined between connector non-activity with glue, modeling, polyurethane iron set
Gap, axis be it is dead, by own material elasticity suppress firmly, over time add doube bridge carload lot it is big, on capital construction building site
Road is bad, and torsion increases, and glue product is easy to aging, and the service life is short.
Doube bridge truck balancing pull rod connector iron-clad in current existing automotive engineering, ball axis are connected in automobile balance drawing
On rod bearing.Effect is to reach balance and stability effect in vehicle traveling process, mitigates the friction of wheel tire and ground, and structure is
In balance set inner cavity, there are connector and fulcrum post in side respectively.
With the passage for using the time, the stability of bulb, mainly due to bulb part wears, will be caused by impression
Gap increases, and is easy to produce shock and vibration, and sound of movement occurs, reduces the service life of pull rod.Therefore it needs to carry out structure to this
It improves.
Utility model content
In view of this, the utility model aim is to provide a kind of ball-head tension rod retaining mechanism, between there is adjusting ball head to wear
The effect of gap compensation dynamics.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is: a kind of ball-head tension rod retaining mechanism, including
Pull rod main body with ball head, first be socketed on ball head locking pedestal, the second locking bottom on ball head top
Seat, the connection ring being threaded on the second locking pedestal, the connection ring and the first locking pedestal are fixed by the first bolt
Connection, the first locking pedestal and the second locking pedestal form the installation cavity for accommodating ball head, and the ball head is close to the first locking
Rubber ring is set at the position of pedestal, and the first locking pedestal is radially provided with mounting hole, installation in the mounting hole

Except seat, the spacing between pedestal and connection ring, i.e., the first locking pedestal and the second locking bottom can also be locked to adjusting first
Spacing between seat.After there is abrasion on the surface of ball head, the second locking pedestal can be continued into precession inside, improve connection
Reliability and compactness.Reinforcing rib then can effectively improve the structural strength of the second locking bed, because of the second locking bed indent, knot
Structure intensity decreases, and keeps stable structure by reinforcing rib, to improve service life.
Concrete scheme as the utility model can be preferred are as follows: the second locking pedestal includes and ball head surface is pasted
The curved surface of conjunction, the recessed bottom of the curved surface are provided with accommodating chamber, are filled with lubricating grease in the accommodating chamber.
By above-mentioned setting, accommodating chamber is primarily to facilitate the storage of lubricating grease, so as to the table of effective protection ball head
Degree of lubrication is improved in face.
Concrete scheme as the utility model can be preferred are as follows: the inside of the connection ring has and the first locking pedestal
Second thread segment of the first thread segment of connection and the second locking pedestal connection, the first thread segment and the second thread segment internal diameter are not
Deng.
By above-mentioned setting, step can be formed in this way, can be easy to differentiate the first thread segment and the second thread segment, not allowed
Easily the installation direction of connection ring is mixed up, is easily installed.
The utility model has the technical effect that following aspect: from many aspects, the tightening state in adjusting ball head portion,
The adjusting of spring makes up so that the tightness of rubber ring is changed so as to play the role of gap, in addition it can
Second locking bed is adjusted, so that the tightness to bulb is also adjusted.

Specific embodiment
Below in conjunction with attached drawing, specific embodiment of the present utility model is described in further detail, so that the utility model skill
Art scheme is more readily understood and grasps.
Embodiment:
Refering to what is shown in Fig. 1, a kind of ball-head tension rod retaining mechanism, including with ball head 14 pull rod main body 1, be socketed in ball
The first locking pedestal 2 on head 14, is threaded in the second locking bottom at the second locking pedestal 3 on the top of ball head 14
Connection ring 4 on seat 3.
Connection ring 4 is fixedly connected with the first locking pedestal 2 by the first bolt 9, and there are three the first bolt 9 tools or three
More than.The location drawing of three the first bolts 9 is illustrated in the present embodiment, it can be with reference to shown in Fig. 2.First bolt 9 directly by
The first locking pedestal 2 and connection are secured under.
First locking pedestal 2 and the second locking pedestal 3 form the installation cavity 5 for accommodating ball head 14, and ball head 14 is close to the
Rubber ring 6 is set at the position of one locking pedestal 2, rubber ring 6 is socketed on ball head 14.Have on ball head 14 for rubber ring
The annular groove of 6 inlay cards, does not illustrate in Fig. 1.
First locking pedestal 2 is radially provided with mounting hole 7, elastic component 8 is equipped in mounting hole 7, mounting hole 7 is close
External threaded one end connects the second bolt 10 for adjusting elastic elastic force potential energy.It is spring, shown spring that elastic component 8, which has,
Two ends have movable block, movable block is iron block, contradict on rubber ring 6, or contradict on the second bolt 10.?
In the present embodiment there are three the second bolt 10 tools, as shown in Figure 2.Second bolt 10 is uniformly arranged on the side of the first locking pedestal 2
On wall.
It returns to shown in Fig. 1, the second locking pedestal 3 and connection ring 4 are threadedly coupled, and are provided with reinforcement on the second locking pedestal 3
Muscle 11.Second locking pedestal 3 and connection ring 4 are threadedly coupled, and have lock except pedestal 3 convenient for assembling second in this way, can be with
Spacing between pedestal 2 and connection ring 4 is locked to adjusting first, i.e., between the first locking pedestal 2 and second are locked between pedestal 3
Away from.After there is abrasion on the surface of ball head 14, the second locking pedestal 3 can be continued into precession inside, improve connection reliability
And compactness.Reinforcing rib 11 then can effectively improve the structural strength of the second locking bed, because the second locking bed indent, structure are strong
Degree decreases, and keeps stable structure by reinforcing rib 11, to improve service life.
Second locking pedestal 3 includes the curved surface 12 with the fitting of 14 surface of ball head, and the recessed bottom of curved surface 12 is provided with appearance
