Abstract
The invention discloses a trailer towing mechanism. The trailer towing mechanism comprises a towing base, and a coupler lock, a lever, an operation rod, a wedge-shaped block, an operation rod spring and a towing pin assembly which are all located at the bottom of the towing base. The coupler lock and the towing base are hinged to each other. The coupler lock can be controlled to rotate and reset. In the trailer towing mechanism, the towing pin assembly comprises a screw, a nut and an insertion pin. The screw penetrates through the lever and the operation rod to be connected with the nut in a screwed mode. A plurality of notches are formed in the axial end face of the nut. The screw comprises a radial through hole. The insertion pin is connected into the through hole in an inserted mode. The two ends of the insertion pin are located in the corresponding notches. By means of the trailer towing mechanism, potential safety hazards caused when the insertion pin falls can be avoided.
Description
Technical field
The invention belongs to a kind of trailer accessory field, be specifically related to a kind of trailer draw gear.
Background technology
Trailer is generally all provided with trailer coupling, trailer coupling generally all includes lever and control lever, described control lever can drive lever to move, including diameter between described lever and control lever is the screw of 16mm and the latch of 2mm, described screw is directly through after lever and control lever, and described latch is horizontally through latch thus lever and control lever are interconnected.But such anatomical connectivity is insecure, and latch easily comes off and causes potential safety hazard.
Summary of the invention
(1) technical matters that will solve
The technical problem to be solved in the present invention to propose a kind of well-set trailer draw gear, to solve the problem that latch comes off.
(2) technical scheme
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of trailer draw gear, comprises traction seat and is all positioned at hook lock, lever, joystick, wedge, joystick spring and the towing pin assembly bottom traction seat;
Described hook lock and traction seat are hinged, and can control the rotatable reset of hook lock;
Described joystick can traction seat can transverse shifting relatively, and the two ends of described joystick spring are connected with traction seat and joystick respectively thus joystick is moved towards traction seat direction;
One end and the traction seat of described lever are hinged, the other end by towing pin assembly and joystick hinged;
Described wedge is connected with lever, and described lever can drive wedge to move to make wedge and hook lock realize locking and coordinates or unblank to coordinate;
In above-mentioned trailer draw gear, described towing pin assembly includes screw, nut and latch; Described screw is spirally connected with nut through after lever and joystick, and the axial end of described nut is provided with several breach, and described screw includes a radial through hole, and described latch is plugged in through hole, and its two ends are positioned at breach.
In above-mentioned trailer draw gear, described screw and nut are welded to each other.
In above-mentioned trailer draw gear, also comprise hook lock spring, the two ends of described hook lock spring connect hook lock and traction seat respectively, and described hook lock spring controls hook lock automatic rotation and resets.
(3) beneficial effect
Trailer draw gear of the present invention, arranges screw and nut structure, improves fastness, and by the mode of latch and nut clamping, so further increase fastness.Weld after screw and nut spins in addition, achieve the connection of multipass approach, thus actv. avoids lever to be separated with joystick, improves safety performance.

Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
A kind of trailer draw gear as Figure 1-Figure 2, comprises traction seat 1 and is all positioned at hook lock 2, lever 3, hook lock spring 8, joystick 4, wedge 5, joystick spring 6 and the towing pin assembly 7 bottom traction seat 1.
Described hook lock 2 is hinged with traction seat 1, and can control the rotatable reset of hook lock 2;
Described joystick 4 can traction seat 1 can transverse shifting relatively, and the two ends of described joystick spring 6 are connected with traction seat 1 and joystick 4 respectively thus joystick 4 is moved towards traction seat 1 direction.
The two ends of described hook lock spring 8 connect hook lock 2 and traction seat 1 respectively, and described hook lock spring 8 controls hook lock 2 automatic rotation and resets.
One end and the traction seat 1 of described lever 3 are hinged, and the other end is hinged by towing pin assembly 7 and joystick 4.
Described traction seat 1 includes traction mouth 11, and described traction mouth 11 is all positioned at traction mouth 11 place for placing described wedge 5 and hook lock 2.
Described wedge 5 is connected with lever 3, and described lever 3 can drive wedge 5 to move to make wedge 5 and hook lock 2 realize locking and coordinates or unblank to coordinate;
As shown in Figure 3 and Figure 4, described towing pin assembly 7 includes screw 71, nut 72 and latch 73; Described screw 71 is through lever 3 and joystick 4 is rear and nut 72 is spirally connected, therefore the fastness that improve between lever 3 and joystick 4, lever 3 is prevented to be separated with joystick 4, the axial end of described nut 72 is provided with 8 breach 74, described screw 71 includes a radial through hole 75, described latch 73 is plugged in through hole 75, its two ends are positioned at breach 74, thus nut loosening can be limited by actv., in order to increase the fastness between lever 3 and joystick 4, the present invention encourages described screw 71 and is welded to each other with nut 72.
Described traction seat 1 includes traction mouth 11, and described traction mouth 11, cooperatively interact between wedge 5 and hook lock 2 interlocking.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
