To this end, the spring is provided in the form of a spiral spring (17) with ends (18, 19) tangentially leading out from the spirals (16), whereby each of the ends (18, 19) is respectively connected to a fixing point of the supporting plate (8) or of the supporting element.
Description
The present invention relates to by the connection of claim 1 a kind of pivotal supporting plate as described in the preamble on a jack.
Jack, promptly those are positioned in the jack on the following settlement, automobile bottom to be hoisted, and the back plate on it normally is being connected on the corresponding supporting member of jack pivotally perpendicular to automobile longitudinal.Thereby can guarantee that this back plate is arranged into below the automobile definitely, this and jack be at the location independent in the direction of autocentre, and irrelevant with the height of the automobile that is raised.
Oneself knows according to DE-GM 74 14 229, through tension spring or the adjustable certain rudimentary horn position of being arranged between back plate and supporting member of making back plate to supporting member of pressure spring.
Above-mentioned design-calculated shortcoming is that it is very complicated that the connection of spring seems, especially all the more so under the situation of setting different settlements aspect the substantially the same jack type for the back plate below automobile.Above-mentioned shortcoming betides following situation especially: aspect the automobile of same type, for example put lowlyer by originating firm requirement automobile, perhaps require bigger chassis degree of freedom aspect cross country car.In order to change this jack, must set different hinge points at back plate or on supporting member, this will improve the manufacturing cost and the housing cost of this jack.
Task of the present invention is to simplify the connection of a kind of pivotal supporting plate on the supporting member of a jack, can pre-determine the initial angle of back plate to supporting member arbitrarily on this jack.
According to the present invention, above-mentioned task is to solve by the feature of claim 1.Some favourable improvement projects are seen described in the claim 2 to 4.
Utilize advantage that the present invention obtains particularly in: back plate is only determined by the angle between the coil spring two ends the initial angle that supporting member sets.Hinge point on the back plate with on supporting member, all keep identical.In addition, a kind of installation of greatly simplifying of spring can realize because helical spring tangentially from two terminations need only be inserted on back plate or supporting member in the best attachment point designed as eyelet, through hole or clamping plate.Under the situation that adopts the plastics forming back plate, above-mentioned the sort of eyelet or through hole can directly be formed on these parts together especially.And under the design-calculated swivel coupling situation as the bolt of the clamping plate of back plate and supporting member, coil spring also can be advantageously to be assembled on its this bolt ground of helix line looping.By above-mentioned favourable design, also can realize helical spring a kind of accurate center fixation.
One embodiment of the present of invention shown in the accompanying drawing will elaborate below.Accompanying drawing is represented:
Fig. 1 is in the pivot arm jack in folded position and the initial position,
Fig. 2 jack shown in Figure 1 is in the top lift position,
The terminal enlarged drawing of the lift of Fig. 3 jack shown in Figure 1,
The front elevation of Fig. 4 Fig. 3.
Following pivot arm jack only is a kind of of jack.But the present invention can use on the various jacks, especially under the settlement on the automobile can begin situation of movement from angle of contact with respect to the supporting member of jack during in lifting.
Fig. 1 and Fig. 2 represent a kind of pivot arm jack, the supporting arm 3 as supporting member that it is provided with a gravity leg 1 and rotatably is attached thereto through a movable joint 2.Through a leading screw 4, this supporting arm 3 is lifted with respect to gravity leg 1.Gravity leg 1 stands on the ground 6 with a leg 5.On the free end of supporting arm 3, settle a back plate 8 through a steering shaft 7 that extends along automobile longitudinal pivotally, this back plate is disposed in the receiving station 9 that is placed in below the car chassis, and lifts automobile.
In Fig. 1, supporting arm illustrates on two positions.Following position represents that jack is in folded position, as it is installed on the automobile.Above the position represent that jack is on the originating location, just be in automobile be not loaded with the perfect position of tire on.On this position, the inevitable starting the most continually of jack, tire changing for example, from summer tire change Tire used in winter into.Also be this position, as described below, in the zero-bit of determining the angle between back plate 8 and the supporting arm 3 on this position.
The locational jack of its top lift that is in shown in Figure 2.
As finding out from Fig. 3 and 4 especially, supporting arm 3 passes through in two clamping plate 10,11 at its free end, and the bolt 12 that these two clamping plate are formed steering shaft 7 penetrates.This bolt 12 also passes the clamping plate 13,14 that are placed on the back plate 8.Back plate is as diecasting making with high-intensity plastics with a kind of hard.It has the flat side head 15 of rounding in addition.This head 15 is passed into downwards in above-mentioned two clamping plate 13,14, and these two clamping plate are also penetrated by above-mentioned bolt 12, so back plate 8 is rotatably mounted on the supporting arm 3.Between clamping plate 13,14, produce a clearance envelope.This clearance envelope is used to hold the helix line 16 of coil spring 17.Helix line 16 bolt 12 with a determining deviation ground looping, so they can not be clamped on this bolt 12, when coil spring is turned.Coil spring 17 is passed into two ends 18,19, and these two ends extend out according to tangential helix line 16 from coil spring 17.One of above-mentioned two ends 18 are inserted in the hole 20 that is arranged on the back plate 8.Thus, coil spring 17 power link to each other with back plate 8 with engaging.The other end 19 of coil spring 17 passes the clamping plate 22 by end wall 21 compression moldings of supporting arm 3.So also being power, coil spring links to each other with supporting arm 3 with engaging.
18,19 angles that constituted each other, end deviate from 180 ° in the present embodiment slightly, and its decision is in the position, angle of the 8 pairs of supporting arms 3 of jack situation lower support plate that do not load.This point refers specifically to the starting position of jack below automobile, as very foregoing.
One when back plate 8 is loaded by vehicle weight, and it is flat being in below the car chassis under the reverse side in the receiving station 9 on arbitrary rotary position supporting arm or rather or jack of automobile and lift location just.When the starting position of jack is low, defined as the front, also above-mentioned situation can appear, even also be like this under and/or the automobile situation that oneself is loaded cranky at tire.Spring force is a design-calculated like this, makes coil spring always be unscrewed or be screwed by vehicle weight, and can not produce a kind of obviously excessive spring force.One when jack is unloaded again, and spring always rotates back into back plate 8 in the starting position of initial specification.
The advantage that above-mentioned solution has is: the angle position that not load of back plate 8 for supporting arm 3 can be regulated arbitrarily, and only the shape by coil spring 17 decides.This position, angle can be in both direction opening or closing and come adaptive various requirement by the helix line 16 of coil spring 17.
The assembling of back plate 8 on supporting arm 3 is simple especially.After in the clamping plate 22 of the end wall 21 that one of coil spring 17 end 19 is inserted into supporting arm 3, then back plate 8 just is sleeved on the other end 18 of coil spring 17 with its hole 20.At this moment, the clamping plate 13,14 of back plate 8 just move on between the clamping plate 10,11 of supporting arm 3.Then, make bolt 12 pass eyelet on the clamping plate 10,11,13,14, and be inserted in the helix line of coil spring 17, and it is pressed on or is riveted on the termination 24 of not being furnished with head 23.
In the present embodiment, design is shaped as slotted hole in the hole 25 of the clamping plate that pass through back plate 8 13,14 that passed by bolt 12.For favourable part that this reached is: back plate 8 can be oblique in a fixed limit introversion along automobile longitudinal with respect to supporting arm 3.Consequently: since automobile forward or backward inclination or can not produce side-bend power because of the longitudinal movement of automobile to jack.
