This connection positioner can be symmetrical arranged with respect to column column cap 2, for example, can be symmetrical arranged this connection positioner in the left and right sides of column column cap 2, and correspondingly, blind hole 21 can be symmetricly set in the left and right sides of column column cap 2.
The bottom surface of blind hole 21 is towards first end of axle body 3, and blind hole 21 has the predetermined degree of depth, and this predetermined degree of depth needs first end of a body 3 is plugged in the blind hole 21, has the gap between the diapire of assurance axle body 3 first ends and blind hole 21 simultaneously.
The cross section of blind hole 21 can be circle, and to cooperate installation better with first end of axle body 3, down, column column cap 2 can be that swing in the axle center with the axle center of blind hole 21 in working order.
Please further with reference to figure 6, Fig. 6 is the back timber structural representation that connects among Fig. 3 in the positioner.
Back timber 1 is provided with the engaging lug 11 relative with blind hole 21 positions, and the number of engaging lug 11 need be provided with according to the number of blind hole 21 and axle body 3, and blind hole 21 and an axle body 3 be corresponding to be provided with an engaging lug 11; Engaging lug 11 is provided with through hole, and second end of axle body 3 runs through the through hole of engaging lug 11 and stretches out from through hole.The shape of through hole cross section can match with the shape of cross section of axle body 3 correspondence positions, and usually, both shapes can be circle, and the inwall of through hole can have the gap with the circumferential side wall of axle body 3 correspondence positions, is beneficial to install.
Can be provided with the earflaps 12 relative with engaging lug 11 positions on the back timber 1, earflaps 12 can be arranged on the diapire of back timber 1, but is not limited thereto, and earflaps 12 also can be arranged on other positions of back timber 1, for example can be arranged on the sidewall of back timber 1.Can be provided with groove 121 on the earflaps 12, positive stop 4 removably is connected in the groove 121.For the operating position, the opening of this groove 121 can be connected with it to make things convenient for positive stop 4 down.
Can be respectively equipped with first pin-and-hole and second pin-and-hole on the cell wall of earflaps 12 further groove 121 both sides, can correspondingly be provided with the 3rd pin-and-hole on the postioning abutment, fixed pin shaft 5 can be set, this fixed pin shaft 5 runs through first pin-and-hole, the 3rd pin-and-hole and second pin-and-hole successively, and positive stop 4 can removably be connected in the groove 121 by fixed pin shaft 5.
One end of fixed pin shaft 5 can be provided with the connection pin-and-hole, connects in the pin-and-hole to be plugged with cottor pin 6, to carry out spacing to fixed pin shaft 5.
Can also be provided with the hemispherical groove 13 of ccontaining column column cap 2 on the diapire of back timber 1, because column column cap 2 can be swung with respect to back timber 1, hemispherical groove 13 is set, under the situation that does not influence 2 swings of column column cap, can makes whole hydraulic rack structure compact more.
The connection positioner that the utility model provides connects bearing pin for dividing body structure, comprises a body 3 and positive stop 4; Has the gap between first end of axle body 3 and the diapire of blind hole 21, stretch out the through hole of the engaging lug 11 of its second end from back timber 1, and the axial arranged outside of its second end has above-described positive stop 4, and this positive stop 4 removably connects by connecting rod and back timber 1.
In the course of the work, owing to have the gap between first end of axle body 3 and the diapire of blind hole 21, column column cap 2 has certain free space and carries out side-to-side vibrations, when 21 diapires of the blind hole on the column column cap 2 touch to the axle body 3 first end time, the active force vertically that passes to a body 3 can significantly reduce; Transitivity according to power, axle body 3 can be given 4 one active forces vertically of positive stop, because axle body 3 is the branch body structure with positive stop 4, in the course of the work, axle body 3 is along with the side-to-side vibrations of column column cap 2, also be in the continuous move left and right, also can produce the gap between axle body 3 and the positive stop 4, the axial force that the existence in this gap makes axle body 3 pass to positive stop 4 equally significantly reduces.
According to the transitivity of power, positive stop 4 can be given shearing force of connecting rod equally, because positive stop 4 is subjected to axial force and significantly reduces, thereby make the shearing force of 4 pairs of connecting rods of positive stop also significantly reduce, therefore, connecting rod is not easy to occur bending and deformation, and can dismantle more easily.
The concrete mode that is connected with back timber 1 by connecting rod for positive stop 4, in a kind of specific embodiment, the connection positioner that the utility model provides, back timber 1 is provided with the earflaps 12 relative with engaging lug 11 positions, earflaps 12 is provided with groove 121, be respectively equipped with first pin-and-hole and second pin-and-hole on the cell wall of groove 121 both sides, corresponding the 3rd pin-and-hole that is provided with on the postioning abutment, positive stop 4 further runs through first pin-and-hole, the 3rd pin-and-hole and second pin-and-hole successively by fixed pin shaft 5, thereby is connected in the groove 121.The connection positioner of She Zhiing is like this realized being connected of positive stops 4 and back timber 1 by fixed pin shaft 5,
Because positive stop is subjected to axial force and significantly reduces, the shearing force of 4 pairs of fixed pin shafts 5 of positive stop also significantly reduces, and fixed pin shaft 5 is not easy to occur bending and deformation, and therefore can more successfully disassemble from pin-and-hole.
Connecting through hole on the positive stop 4 both can be a screwed hole, also can be unthreaded hole, can also be the through hole with part screw thread.Through hole with part screw thread both had been easy to dismounting, also made set bolt more firm with being connected of back timber 1 simultaneously.
Please further with reference to figure 7, Fig. 7 is the axle body construction schematic diagram that connects among Fig. 3 in the positioner.
In another preferred embodiment, the connection positioner that the utility model provides can be provided with dismounting groove 31 on the axle body 3.Dismounting groove 31 is set, when dismounting, can comes shifting axle body 3, make a body 3 be easier to hold, so that dismounting is more successfully carried out by dismounting groove 31.
Dismounting groove 31 can be arranged at second end of a body 3, and the axial arranged outside of second end of axle body 3 has positive stop 4, with dismantling second end that groove 31 is arranged at a body 3, can dismantle positive stop 4 more easily.
Dismounting groove 31 can be the cannelure of circumferential setting along axle body 3, and the dismounting groove 31 of She Zhiing is simple in structure, easy to process like this.
More than a kind of connection positioner provided by the utility model is described in detail.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
