Description
Technical field
The utility model relates to lorry accessory technical fields, and in particular to the hitch frame for lorry.
Background technique
The full trailor of lorry have many uses in transport service it is general, generally in order to save transportation cost, by tractor and trailer
It is attached by hitch frame, to transport more article, hitch frame is used to reduce the turning radius of vehicle in trailer, with drop
Requirement of the low vehicle to road, parking space etc..But inevitably will do it steering during tractor moves ahead, in rotation process
In it is larger to towing pin abrasion in hitch frame, it is especially the most serious to the abrasion of the upper and lower ends of towing pin.Meanwhile working as tractor
When stopping, subsequent trailer is had due to effect of inertia and is continued forward trend, at this moment can form an impact force to towing pin
Hitch frame is damaged, towing pin is easily broken off by prolonged abrasion, collision, leads to tractor and extension in vehicle travel process
Vehicle can separate, and there is very big road traffic safety hidden danger.
For this purpose, Chinese patent notification number is that CN207028738U discloses a kind of vehicle hitch frame, including main frame, fixation
Plate and towing pin, one end of main frame are fixed with fixed plate, and the other end of main frame is equipped with lifting lug, and lifting lug is equipped with pin
Frame, the interior rotation of pin frame are equipped with towing pin, and the side of fixed plate is equipped with mounting base, and fixation is set between mounting base and fixed plate
There is connecting column, the periphery of connecting column is equipped with several dampers, and damper is fixed between mounting base and fixed plate.This reality
It is simple with new structure, it is easy to use, the abrasion of towing pin can be reduced, while preventing the collision of towing pin, extend hitch frame
Service life.But above scheme has the following problems: when road conditions are bad in lorry traveling, lorry generates biggish vibration,
Towing pin in hitch frame is deviate from from pin hole, causes the rope of towing pin loss or dilatory article to fall off, or even cause people
The injures and deaths of member or the loss of property.
Utility model content
The utility model is intended to provide the hitch frame for being used for lorry, avoids towing pin from deviating from from pin hole, eliminates lorry
Security risk.
In order to achieve the above objectives, the utility model adopts the following technical solution: for the hitch frame of lorry, including main frame
And towing pin, the side of main frame are fixedly connected with lifting lug, and the towing pad with towing pin cooperation is offered on lifting lug, main frame
The other side is fixedly connected with fixed mechanism, and the escapement being of an L-shaped structure is rotatably connected on lifting lug, and escapement includes vertical
Bar and horizon bar, vertical bar are fixedly connected with horizon bar, and the end of vertical bar and the upper surface of lifting lug are rotatablely connected, horizon bar
Lower end surface is fixedly connected with the lid with towing pin cooperation, and lid offers bayonet, the two sides of bayonet close to the side of towing pin
It is hinged with snap-gauge, snap-gauge is connected by the inside of the first spring and lid, and the frontal projected area of lid is greater than the positive throwing of towing pin
Shadow area；The upper surface of lifting lug is fixedly connected with limited block far from the side of bayonet.
The utility model has the advantages that
1, escapement is arranged in the utility model on lifting lug, by rotating vertical bar, to drive horizon bar and level
The lid of bar lower end surface is rotated to towing pin direction, when the bayonet of lid is in contact with towing pin, is continued to rotate vertical bar, is led
Drawing pin will push snap-gauge to lid medial motion, and such towing pin is stuck in cover inside.By the way that the structure is arranged, to towing pin
Top is limited, and towing pad plays certain position-limiting action to towing pin itself, when the road conditions of lorry traveling are bad, is avoided
Towing pin is deviate from from towing pad, eliminates the security risk of lorry.
2, limited block is set in the utility model, escapement is limited so that escapement along single direction into
Row rotation.Meanwhile towing pin, when being stuck in lid, for towing pin in the case where no external force is assisted, towing pin can not be from lid
Interior abjection, towing pin itself are used as the locking structure to escapement, without in addition increasing lockable mechanism, so that total is simple
It is single, it is easy to operate.
Further, the first mounting hole is offered on lifting lug, vertical bar passes through the first mounting hole, and vertical bar is located at the upper of lifting lug
Side offers the second mounting hole, and the first pin shaft is equipped in the second mounting hole, and vertical bar, which is located at below lifting lug, offers third peace
Hole is filled, is equipped with the second pin shaft in third mounting hole, the axis of the second mounting hole and third mounting hole is mutually perpendicular to vertical bar.It is logical
The structure is crossed, so that vertical bar is rotated along the upper surface of lifting lug, and vertical bar is carried out by the first pin shaft and the second pin shaft
Limit is dismantled more convenient.
Further, lifting lug includes upper plate, lower plate and side plate, and upper plate is connected with lower plate by side plate, and side plate and main frame are solid
Fixed connection.By the way that the structure of lifting lug is arranged, convenient for hitch frame and tractor to be attached, connect than stronger.
Further, the upper inside wall of lid is fixedly connected with elastic cushion.When the traveling road conditions of lorry are bad, towing pin meeting
The vertical tremor in towing pad plays buffer function to towing pin, and can avoid towing pin and constantly hit by the way that elastic cushion is arranged
The top of lid and generate noise.
Further, fixed mechanism includes fixed plate and mounting plate, is connected between fixed plate and mounting plate by connecting rod, Gu
Fixed board is fixedly connected far from the side of connecting rod with main frame, and the 4th mounting hole is offered on mounting plate.By the way that fixed machine is arranged
Structure is classified as fixed plate and mounting plate, increases the distance between hitch frame and trailer, provides installation and service clearance.
