Abstract

The invention discloses a vehicular tyre wrench combined with a towing hook ring. The vehicular tyre wrench comprises an internal hexagonal sleeve and a handle lever, and is characterized in that the front end of the tyre wrench is the internal hexagonal sleeve which is fixedly connected with the handle lever of the tyre wrench to form a whole body; a rear end section of the handle lever is provided with a threaded section which can be in screwing connection with a corresponding thread of a head part section of a vehicular towing hook ring; and a connection thread of the end part of the towing hook ring can be matched with the thread formed at the connection part of an automobile to which the connection thread belongs. The vehicular tyre wrench combined with the towing hook ring has the advantages that: as the thread pre-formed at one end of the tyre wrench which is provided with the internal hexagonal sleeve can be matched with the thread of the towing hook ring which is originally used for towing a vehicle in an emergency to form a lengthened wrench tool, the aim of easily and stably using the towing hook ring as a prolonged handle lever of the wrench can be fulfilled on the premise of basically not increasing the cost, an operator has a good handfeel on the ring arranged at the rear part of the towing hook ring, and the effect of applying force is obvious.

Description

Combination towing hook ring with the tire for vehicles spanner

Technical field

The present invention relates to tyre wrench, especially relate to a kind of automobile with the automobile-used tyre wrench that can be used in combination with the Automotive Drawbar ring.

Background technology

Though traditional tyre wrench is in structure, form, the purposes each side has had big improvement, the diversity of pattern also has been suitable for many different actions, but its cost increase of spanner preferably of some function is more after all, directly influenced cost performance as available attachment, some combination wrench that can reduce cost is then given a strained interpretation, Chinese patent ZL93215071.3 discloses a kind of by sleeve, the Wrench of " convenience type multifunctional tire spanner " by name that connecting rod and drive rod are formed, though the dismantled and assembled characteristics of tool, but tend to lose sub-assembly with the car keeping or in using, and the fit clearance that the part of instrument and the loose joint of part bring, make in the dismounting tire bolt unsatisfactory, its jack depression bar of being made by thin-walled material of using is suitable for the jack operation handle than the laborsaving function of tool often again, and not too be suitable for the occasion of the bigger dismounting tire bolt of operating physical force, sometimes in bolt assembly is got rusty in dismounting, especially can be at palm, pin is stepped on etc. under the actual working state, make and join the very fast damage of the drive rod of making in the jack depression bar originally, causing described tyre wrench thus lost efficacy with the car jack time, the emergency that has directly influenced two cover driver's tools is used, and makes open-air vehicle-mounted maintenance that difficulty take place.

Summary of the invention

Situation or deficiency in view of above-mentioned correlation technique, the objective of the invention is to propose a kind ofly can satisfy with the dismounting of vehicle tyre bolt, not only can when using the big spin of spanner demand, easily change new departure of the tyre wrench of the combined transformation of spanner and combination back but also tool stable operation performance with plain mode, substantially do not increasing under the prerequisite of manufacturing cost, spanner partial structurtes key element is made very little change and then tried to achieve stable lever combination.

Above-mentioned purpose of the present invention is achieved through the following technical solutions: a kind of tyre wrench that makes up the towing hook ring, Hexagonal jacket and handlebar in comprising, it is characterized in that: the front end of tyre wrench is one to connect firmly the interior Hexagonal jacket of one with its handlebar, and the rear end section of handlebar is provided with one can screw the thread segment that connects with the head sections respective threaded of towing hook ring with automobile; The connection screw thread of towing hook ring end should can cooperate with the screw thread of automobile connection place under it.

The beneficial effect that the present invention compared with prior art has is: because the default screw thread of tyre wrench one end of Hexagonal jacket can be combined into the Wrench of lengthening with the former threaded engagement that is used for the towing hook ring that emergent trailer uses in having, prolong the effectiveness of handlebar as spanner so under the prerequisite that does not increase cost substantially, can easily, firmly realize the towing hook ring, and the operator is to the good hand touch at towing hook ring rear annular place, and afterburning effect is obvious.

The parts title is as follows shown in each label of accompanying drawing:

1 tyre wrench, 2 interior Hexagonal jackets, 3 towing hook rings, 4 internal threads, 5 external screw threads, 6 ring portions, 7 screw thread pairs, 8 tyre wrench, 9 interior Hexagonal jackets, 10 towing hook rings, 11 external screw threads, 12 internal threads, 13 ring portions, 14 screw thread pairs.

The specific embodiment

The invention will be further described below in conjunction with the accompanying drawing of embodiment, will help the understanding to the technology of the present invention content and effect, but embodiment do not constitute the restriction to technical solution of the present invention.

Fig. 1 is the basic model tyre wrench of the embodiment one of the described invention of this case, when general dismounting tire bolt, just can use it comparatively easily, but when the handle active force is not enough to overcome the moment of resistance, towing hook ring 3 and tyre wrench 1 can be integrated, its combination is to screw into screw thread pair 7 with external screw thread 5 intrinsic on internal thread prefabricated on the tyre wrench 14 and the towing hook ring 3; In like manner, Fig. 5 is the basic model tyre wrench of the embodiment two of the described invention of this case, when general dismounting tire bolt, just can use it comparatively easily, but when the handle active force is not enough to overcome the moment of resistance, towing hook ring 10 and tyre wrench 8 can be integrated, its combination is to screw into screw thread pair 14 with internal thread 12 intrinsic on external screw thread prefabricated on the tyre wrench 8 11 and the towing hook ring 10; And the ring portion 6 on two kinds of pattern towing hook rings or 13 couples of operators' the application of force is pleasant favourable; Again within the described embodiment one of this case within Hexagonal jacket 2 or the embodiment two Hexagonal jacket 9 be fixedly connected with tyre wrench 1 and tyre wrench 8 respectively, the operation that its globality is brought is smooth and easy to be self-evident.

Claims
