The utility model discloses a simple and easy-to-use jack, which relates to the technical field of lifting devices, comprising a scissor lifting device, a transmission screw, a universal rotation structure, a connecting rod and a ratchet wrench, and is characterized in that the transmission screw One end of the universal rotating structure is sleeve-connected, the other end of the universal rotating structure is sleeve-connected with one end of the connecting rod, and the other end of the connecting rod is connected with the ratchet wrench. The combination of the universal rotating structure and the ratchet wrench saves time and effort in use, and avoids injury to the user during use.
Description
Technical field
The utility model relates to a kind of hoisting device technical field, especially a kind of jack that is simple and easy to use.
Background technology
At present, the scissor-like jack that automobile is conventional, comprise base and back-up block, between base and back-up block, by upper bracket, be connected with lower bracket, upper bracket and lower bracket hinged place arrange drive screw, one end of drive screw is provided with U-shaped connecting bridge, by rocking bar, connecting U-shaped connecting bridge rotarily drives screw rod and rotates, easily there is slippage in U-shaped connecting bridge in the process of rotation, due to rocking bar limited length, rotating torque is short, so rotate very effort, and user is also easy and ground and vehicle body generation collision when rotating rocking arm, to use, bring inconvenience, exist some potential safety hazards.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple to operate, time saving and energy saving jack that is simple and easy to use.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of jack that is simple and easy to use, comprise that scissors play falling unit, drive screw, universal rotational structure, pipe link and free wrench, it is characterized in that described drive screw is connected with one end sleeve-type of described universal rotational structure, the other end of described universal rotational structure is connected with one end sleeve-type of described pipe link, and the other end of described pipe link is connected with described free wrench.
The square projection of described drive screw coupling end, the transmission shaft of described universal rotational structure is provided with the square groove corresponding with described drive screw coupling end.
The square projection of described pipe link and described universal rotational structure coupling end, the transmission shaft of described universal rotational structure is provided with corresponding square groove with described pipe link coupling end.
The square projection of described pipe link and described free wrench coupling end, described free wrench is provided with corresponding square hole with described pipe link coupling end.
Described pipe link is provided with external extension rod.
Described extension rod and described pipe link coupling end are provided with corresponding square groove, and the set square hole of the square projection of the described extension rod other end and described free wrench is suitable.
The beneficial effect that adopts technique scheme to produce is: the utility model has made original U-shaped connection structure into fabricate block that free wrench is connected with universal structure, jack is in ascending, descending process, its universal structure can change direction, having guaranteed that connecting bridge is unlikely gets loose, also guaranteed that free wrench can not produce friction and collision with vehicle body and ground in rotary course simultaneously, by increasing the pipe link of different length, can be applicable to various operating environments, avoid the in use injury to user of service.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model integral structure schematic diagram.
As described in Figure 1: 1 scissors play falling unit, 2 drive screies, 3 universal rotational structures, 4 free wrenchs, 5 pipe links.
The specific embodiment
As shown in Figure 1, a kind of jack that is simple and easy to use, comprise that scissors play falling unit 1, drive screw 2, universal rotational structure 3, pipe link 5 and free wrench 4, it is characterized in that described drive screw 2 is connected with one end sleeve-type of described universal rotational structure 3, the other end of described universal rotational structure 3 is connected with one end sleeve-type of described pipe link 5, the other end of described pipe link 5 is connected with described ratchet wrench 4 hands, the square projection of described drive screw 2 coupling ends, the transmission shaft of described universal rotational structure 3 is provided with the square groove corresponding with described drive screw 2 coupling ends, the square projection of described pipe link 5 and described universal rotational structure 3 coupling ends, the transmission shaft of described universal rotational structure 3 is provided with corresponding square groove with described pipe link 5 coupling ends, the square projection of described pipe link 5 and described free wrench 4 coupling ends, described free wrench 4 is provided with corresponding square hole with described pipe link 5 coupling ends, described pipe link 5 is provided with external extension rod, described extension rod and described pipe link 5 coupling ends are provided with corresponding square groove, the set square hole of the square projection of the described extension rod other end and described free wrench 4 is suitable.
The utility model has made original U-shaped connection structure into fabricate block that free wrench is connected with universal structure, jack is in ascending, descending process, its universal structure can change direction, having guaranteed that connecting bridge is unlikely gets loose, also guaranteed that machine-processed spanner can not produce friction and collision with vehicle body and ground in rotary course simultaneously, by increasing the pipe link of different length, can be applicable to various operating environments, avoided the in use injury to user of service.
