Description
Technical field
The present invention relates to lifting gear parts, specifically a kind of folding tyre wrench for safeguarding vehicle.
Background technology
In the maintenance maintenance lifting gear of such as all kinds of automobile, horizontal hydraulic workshop jack, hoisting jack, screw jack and scissor-like jack are there is in large quantities, universal due to family-sized car, with the supporting scissor-like jack of car because of the excellent safety in utilization of its lightweight He More, reliability and being widely used.The power that such scissor-like jack rises with screw thread pair transmission, have the excellent feature making to be realized at any height and position by jacking vehicle mechanical caging, the kinetic moment rotated needed for scissor-like jack screw rod then needs to impose on suitable twisting resistance to realize as power arm with the tyre wrench that has operating grip concurrently.This operating grip as power arm is general with it with the tyre wrench installing and removing wheel of vehicle, thus, tyre wrench with regard to subject application is got on very well, and such tyre wrench will have good serviceability just must have the arm of force pattern of enough structural strengths, size reasonable.Usual existing tyre wrench power arm is that the storage in the majority of single-unit is very inconvenient, be designed to once in a while can the extension handle of pull also because the fit clearance between the joint arm of force of front and back controls bad and make instrument in use in rocking situation, directly affect operating effect.
Summary of the invention
The power arm of scissor-like jack twist thread pair and the in esse storage inconvenience of tyre wrench of mounting or dismounting wheel tyre locknut is common in view of above-mentioned, coordinate the shortcoming of rocking the result of use difference brought, engineers through earnest analytical study think this tyre wrench should be designed to by prosthomere handle hinge extend handle and be added on mechanical transposition lock structure as well, it is active that rotation between each sub-assembly of tyre wrench formed connects palpus folding, location is correct, locking is reliable, the tolerance band of the action required power of being separated with prosthomere handle by extension handle is 30 ~ 65 newton, and extension handle is incorporated into the tolerance band of action required power in prosthomere handle in 50 ~ 90 newton, the moment of torsion of 150Nm is applied for rating test moment of torsion Gn to operate the tire handle launched completely, then with 1.5 of Gn times for long duration test moment of torsion, the test of the long duration test moment of torsion of 260 times will be passed through, with the prescribed torque that the rating test moment of torsion of 2.5 times is strength test, after once continuing the strength test of 30 seconds, tyre wrench is without permanent deformation and the mutual interference that do not produce between structural member that various impact normally uses.But old money tyre wrench before is then difficult to reach above-mentioned relevant U.S.'s product standard or technical specification.
Above-mentioned purpose of the present invention is achieved in that a kind of tyre wrench, comprises sleeve part and handle component, it is characterized in that: handle component is implemented to rotate connection with extending handle with the second rotating pin in one end section of prosthomere handle; Implement to connect with the rotation of sleeve part with the first rotating pin at the other end of prosthomere handle; Using the big groove end face of prosthomere handle as sleeve part around the spacing buting iron of the first rotating pin expanded angle; Be provided with big groove in the large end section of the inner groovy of prosthomere handle and connect little groove through groove changeover portion; The open-end segment place of little groove is provided with Left-Hand Panel and right panel; The little groove end face of little groove is provided with and extends the spacing lug of rotatable handle; Left-Hand Panel and right panel are provided with the little groove of arc-shaped first of indent evagination, the second little groove, the 3rd little groove, the 4th little groove respectively, and be provided with the first top cap stay cave and second top cap stay cave, and the first little groove is identical with the 3rd little groove pattern, positional symmetry, second little groove is identical with the 4th little groove pattern, positional symmetry, and cave and first stayed by the second top cap, and to push up cap pattern in cave identical, positional symmetry, the left pin shaft hole of setting and right pin shaft hole are coaxial aperture; The cross section, extension extending handle is circular, the groove section left and right sides being " U " shape opening at it is through with the second rotating pin mating holes, and puts at the parallel position with described second rotating pin mating holes center line the left side slip hole and right side slip hole that are provided with and have same centerline hole; The small end section of extension handle is provided with the sled tire flange in " V " font, and fragment position is provided with utensil locating hole wherein, and overlaps as coaxial aperture with the through hole of the little bottom portion of groove of prosthomere handle relative to the axial line symmetry of the second rotating pin; The coil portion of locating tensioning torsion spring is placed in the groove segment type chamber of " U " shape opening below the second rotating pin, and each spring pin place of locating tensioning torsion spring is overlapped respectively the first slippage top cap and the second slippage top cap; The cylindrical of the second slippage top cap and left side slip hole are formed and move axially pair, and the cylindrical of the first slippage top cap and right side slip hole form another and move axially pair.
Wherein, axis hole matched in clearance is implemented with the endoporus of the first slippage top cap and the endoporus of the second slippage top cap respectively at each spring pin cylindrical shell of column of described locating tensioning torsion spring;
Wherein, when sleeve part is contained, sleeve part is in the default die cavity of big groove just;
Wherein, extend handle when being contained, locating tensioning torsion spring pass through respectively the first slippage top cap head of right side slip hole and left side slip hole, the second slippage top cap head under the effect of torsion spring tension force respectively by positioning fastener at the 3rd little groove die cavity and the first little groove die cavity; The large portion extending handle body is then threaded in the default die cavity of the little groove of handle component;
Wherein, when extension handle is fully stretched, under the tension force effect of locating tensioning torsion spring, described first slippage top cap is crossed the 4th little groove and is slipped into the first top cap locking in cave, and meanwhile, described second slippage top cap is crossed the second little groove and slipped into the second top cap locking in cave;
Wherein, when described extension handle is stretch-like, the inner plane of the groove section of " U " shape opening and spacing lug adjoin;
Wherein, through little interior hexagonal die cavity is provided with in the two sides of described prosthomere handle.
The beneficial effect that the present invention compared with prior art has is: with related rotation duplicate invoice knot sleeve part and the tyre wrench extending handle, built-in locating tensioning torsion spring coordinates each structural element, change the imprecision between traditional design structural member, relevant factor, loosen, abnormal sound, location are unreliable, the defect of mechanical strength, poor rigidity, substantially increase safety in utilization and the reliability of Wrench.
