For this reason, tie rod assembly of the present utility model adopts following technical scheme:
A kind of tie rod assembly comprises that the ball key seat and the ball pin of top end opening, the bulb of described ball pin are nested in the described ball key seat and can rotate along described ball key seat inwall, and the top of described bulb cooperates with described ball key seat and forms the oiling cavity; Pull bar has externally threaded adjustment screw rod in the setting of the two ends of described pull bar;
Side extension at described ball key seat is provided with screwed pipe, and the external diameter of the internal diameter of described screwed pipe and described adjustment screw rod is suitable, and described screwed pipe inwall is provided with and the suitable negative thread of described outside thread;
Along the bearing of trend of described screwed pipe, on the outer wall of described screwed pipe, be vertically arranged with two relative extension edges, be formed with slit between two described extension edges, described slit is connected with described screwed pipe inwall; Connect two described extension edges and be provided with at least two bolts hole, the described bolt hole of bolt-through carries out fastening to described screwed pipe.
Outside described bolt, be set with jam nut.
Socket is provided with oscillating bearing on described ball key seat inwall, and described bulb is nested in described oscillating bearing inside and can rotates along described oscillating bearing.
At the opening part of described ball key seat, be provided with and be used for described opening is carried out osed top ball key seat lid.
Described ball key seat lid has the extension arm towards described bulb, and described extension arm is nested in the described oiling cavity.
Also comprise the oil nipple that is connected with described oiling cavity.
Technique scheme of the present utility model has the following advantages compared to existing technology:
(1) tie rod assembly described in the utility model, at the adjustment screw flight bonded assembly of realizing ball key seat screwed pipe and pull bar simultaneously, also realize described screwed pipe is carried out fastening, make the pull bar of tie rod assembly described in the utility model and the problem that running can not appear owing to the wearing and tearing of screw thread in connection between the ball key seat compared to prior art by the bolt on the extension edge that is arranged on described screwed pipe.
(2) tie rod assembly described in the utility model is provided with described ball key seat lid, has avoided the volatilization of oiling cavity inside lubricating oil, so do not need compared to prior art frequently to bring great convenience to the user to the oiling of described oiling cavity.
Further, in the tie rod assembly described in the utility model, described ball key seat is set covers the extension arm that has towards described bulb, described extension arm is nested in the described oiling cavity, thereby can further seal the faying face between described ball key seat and the ball key seat lid by described extension arm, thereby guarantee that more lubricating oil is in the sealed chamber that can not cause the lubricating oil volatilization as far as possible.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, according to specific embodiment of the utility model also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is the utility model tierod assembly structure scheme drawing;
Fig. 2 is the lateral plan of the total balling-up key seat of the utility model tierod;
Reference numeral is expressed as among the figure: the 1-pull bar, and 11-adjusts screw rod, 2-ball key seat, 3-oscillating bearing, 4-ball pin, 41-bulb, the 5-jam nut, 6-ball key seat lid, 61-oiling cavity, 62-opening, 63-extension arm, 64-oil nipple, the 7-screwed pipe, 71-extension edge, 72-bolt hole, 73-slit, 8-bolt.
The specific embodiment
As shown in Figure 1, the utility model tie rod assembly, the ball key seat 2 and the ball pin 4 that comprise top end opening, the bulb 41 of described ball pin 4 are nested in the described ball key seat 2 and can rotate along described ball key seat 2 inwalls, and the top of described bulb 41 cooperates with described ball key seat 2 and forms oiling cavity 61; Pull bar 1 has externally threaded adjustment screw rod 11 in the setting of the two ends of described pull bar 1.
As can be seen from Figure 2, extend in a side of described ball key seat 2 and to be provided with screwed pipe 7, the external diameter of the internal diameter of described screwed pipe 7 and described adjustment screw rod 11 is suitable, and described screwed pipe 7 inwalls are provided with and the suitable negative thread of described outside thread; Along the bearing of trend of described screwed pipe 7, be formed with slit 73 being vertically arranged with on the outer wall of described screwed pipe 7 between 71, two described extension edges 71 of two relative extension edges, described slit 71 is connected with described screwed pipe 7 inwalls; Connect two described extension edges 71 and be provided with at least two bolts hole 72, bolt 8 runs through 72 pairs of described screwed pipes 7 of described bolt hole and carries out fastening.As preferred embodiment, connect two described extension edges 71 and be provided with two bolts hole 72, and outside described bolt 8, be set with jam nut 5.Jam nut 5 plays the effect that prevents that bolt 8 from becoming flexible from bolt hole 72.
