The utility model discloses a saddle-type traction seat which comprises a traction seat board and support seats arranged on two sides of the traction seat board, wherein a sliding guide rail is fixed below a square frame between the two support seats; a lock bolt is arranged on the sliding guide rail; the lock bolt is connected with a pull handle through a loosing rod; an insurance baffle is arranged beside the pull handle; a tension spring is connected on the pull handle in a hanging way, and the other end of the tension spring is connected on a support plate of the traction seat board; a lock hook is arranged on the lock bolt; the lock hook is mounted on the inner wall of the square frame of the traction seat board; and a bulge on the lock hook is connected with the top end of the inner wall of the square frame through a tension spring of the lock hook. The saddle-type traction seat has a simple structure, when a carriage is connected with a trailer, the insurance baffle is pushed aside, the pull handle is pulled outward, an opening of the lock hook is opened, so that a traction pin of the carriage enters the opening of the lock hook, and then the traction pin reaches the limiting position, the lock bolt automatically reaches a preset position under the pulling action of the tension spring to lock the lock hook, so that the safety performance of the traction seat is greatly improved.

Description

A kind of saddle traction seat

Technical field

The utility model relates to a kind of draw gear, more particularly, relates in particular to a kind of saddle traction seat, belongs to technical field of automobile parts.

Background technology

Continuous growth along with trade of goods activity; Transit industry is also developed thereupon; And it is the most outstanding with the development of heavy trucking and freight container traffic; Thereby promoted the development of trailer relevant industries, the loading wheel tractor that superimposed trailer is big as a kind of load carrying ability, load-carrying capacity is high more and more is used widely.And the saddle traction seat is installed on the tractor truck as the vitals of semi-trailer automobile, its effect be realize between wheel tractor and the superimposed trailer connection, affect and separate.But traction seat of the prior art not only complex structure, productive costs is higher, and safety performance is lower when using, and serious safety problem takes place misoperation easily.

The utility model content

The purpose of the utility model is the deficiency to above-mentioned prior art, and a kind of simple in structure, saddle traction seat that safety performance is high is provided.

For realizing above-mentioned purpose; The saddle traction seat that the utility model provided comprises the traction seat board that is the inverted V-shaped opening, and a bearing is respectively established on the both sides of traction seat board lower surface; Be fixed with slide rail under the square frame between said two bearings; Slide rail is provided with locking bolt, and said locking bolt is connected with the medial concavity of trip lever through the locking bolt pin, and the upper end of said trip lever connects handle through the eye bolt assembly; The next door of handle is provided with safety screen, and handle is provided with spring hanging plate, is mounted with extension spring on the spring hanging plate, and the other end of extension spring articulates on the support plate of traction seat board; Locking bolt is provided with latch hook, and said latch hook is installed in through lock hook pin on the square frame inwall of traction seat board, and the convexity on the latch hook is connected with square frame inwall top through the latch hook extension spring; The adjusting screw(rod) relative with the free end of said latch hook is threaded on the said traction seat board.

The utility model saddle traction seat is simple in structure; When the compartment is connected with trailer, push safety screen aside and outwards spur handle, open the opening of latch hook; Make the opening of the towing pin entering latch hook in compartment; When towing pin reached the limit of the position, locking bolt reached the desired location automatically latch hook is carried out locking under the tension of extension spring, improved the safety performance of traction seat greatly.

Among the figure: 1-draws seat board; The 11-safety screen; The 12-Insurance Block; The 13-wear ring; The 2-bearing; The 3-latch hook; The 31-lock hook pin; The extension spring of 4-latch hook; The 5-handle; The 51-bayonet socket; The 52-draw-in groove; The 53-spring hanging plate; The 6-extension spring; The 7-trip lever; The 8-locking bolt; 81-locking bolt pin; The 9-slide rail; The 10-adjusting screw(rod).

The specific embodiment

Below in conjunction with the embodiment in the accompanying drawing the utility model is done further to specify, but do not constitute any restriction the utility model.

Consult illustrated in figures 1 and 2; The utility model saddle traction seat comprises the traction seat board 1 that is the inverted V-shaped opening, and a bearing 2 is respectively established on the both sides of traction seat board 1 lower surface; Be fixed with slide rail 9 under the square frame between this two bearing 2; Slide rail 9 is provided with locking bolt 8, and locking bolt 8 is connected with the medial concavity of trip lever 7 through locking bolt pin 81, and the upper end of said trip lever 7 connects handle 5 through the eye bolt assembly.Handle 5 is provided with bayonet socket 51, draw-in groove 52 and spring hanging plate 53, and when handle 5 was not drawn out traction seat board 1, bayonet socket 51 was stuck on traction seat board 1 madial wall; Be mounted with extension spring 6 on the spring hanging plate 53, the other end of extension spring 6 articulates on the support plate of traction seat board 1.The next door of handle 5 is provided with safety screen 11, and safety screen 11 is installed on the Insurance Block 12 of traction seat board 1 through assemblies such as torsion spring, bolt, nuts.Locking bolt 8 is provided with latch hook 3, and this latch hook 3 is installed in through lock hook pin 31 on the square frame inwall of traction seat board 1, and the convexity on the latch hook 3 is connected with square frame inwall top through latch hook extension spring 4.Draw the adjusting screw(rod) 10 relative that be threaded on the seat board 1, be used to limit the position that locking bolt 8 slides to the right, play position-limiting action with the free end of said locking bolt 8.Because towing pin frequently turnover causes certain wearing and tearing can for traction seat board 1, therefore is provided with wear ring 13 in the upper surface of traction seat board 1.

When the compartment is connected with trailer; Earlier with 11 groups of safety screens on one side; Pulling handle 5 makes bayonet socket 51 break away from the madial wall of traction seat board 1; Then outwards pulling handle 5 is pulled handle 5 once more draw-in groove 52 is stuck on the lateral wall of traction seat board 1 outside draw-in groove 52 exposes traction seat board 1, makes handle 5 fixed.In the process of pulling handle 5, handle 5 drives locking bolt 8 through trip lever 7 and on slide rail 9, slides left, spurs extension spring 6 simultaneously and makes it be in extended state.After locking bolt 8 slides left, latch hook 3 just under the tension of latch hook extension spring 4 around lock hook pin 31 left-hand revolutions, open the opening of latch hook 3, this moment latch hook 3 opening direction consistent with the inverted V-shaped opening of traction seat 1.

The towing pin that is contained on the compartment gets into latch hook 3 along opening, in the entering process, and towing pin collision latch hook 3; Latch hook 3 is clockwise rotated around lock hook pin 31, and in latch hook 3 rotating process, the long arm end of latch hook 3 extruding locking bolt 8 is moved to the left it; 8 of locking bolts make draw-in groove 52 break away from the lateral wall of traction seat boards 1 through trip lever 7 dual locks 5, shake hands this moment 5 to be in the state of getting loose, can be toward moving right under the tension of extension spring 6; Driving locking bolt 8 through trip lever 7 simultaneously moves right until latch hook 3 locks are firm; And safety screen 11 this moment also under the effect of torsion spring automatic homing block handle 5, handle 5 can not be swung back and forth, play safety effect.

When trailer and car separated, only need the repetition above-mentioned steps to push safety screen 11 and outside pulling handle 5 aside, open the opening of latch hook 3, towing pin skids off latch hook 3 along opening, and handle 5 can set back under the effect of extension spring 6.
