Abstract
The utility model relates to a rigid pole for a driver examination, which comprises a pole body and a spring component used for connecting the pole body with a door frame beam, wherein an upper connecting pole and a lower connecting pole are connected through a spring to form the spring component and are in cuttage grafting through a conical lug and a conical groove arranged at the connecting end of the connecting pole and the lower connecting pole, and cone angles of the conical lug and the conical groove are larger than 20 degrees and smaller than 50 degrees. The utility model provides the pole spring component which can satisfy the return static time requirement of a swaying pole and has lower processing cost.
Description
Technical field
The utility model relates to the stake bar spring assembly that a kind of driving test is used.
Background technology
At present, in human pilot training and the examination, need use relevant examination training device, when the exercise inbound/outbound process, what use at present is that the device of portal frame and both sides stake bar is trained and taken an examination.And the stake bar of both sides is bumped by the wiping of student's car through regular meeting; cause rocking of a bar; in order to make a bar rock return and static at short notice; present stake bar lower end is equipped with iron block; and with corresponding position, stake bar lower end; be provided with magnet on the ground, can make the stake bar that rocks static rapidly like this by the magnetic force between iron block and the magnet.But the magnetic force between iron block and the magnet is limited after all, can only make the stake bar that rocks static as early as possible, but does not still reach at present the industry requirement for 20 seconds stall of stake bar of rocking, and this set increased the manufacturing cost of stake bar, and iron block gets rusty easily.
The utility model content
The utility model relates to and has developed the satisfied stake bar stall time requirement of rocking of a kind of energy at the deficiencies in the prior art, and the lower stake bar spring assembly of processing cost.
The utility model is achieved through the following technical solutions:
The driver takes an examination and uses the rigid pile bar, the stake bar is made of the body of rod and the spring assembly that is used for connecting-rod body and door frame crossbeam, described spring assembly is linked into an integrated entity upper and lower connecting link two parts by spring, and upper connecting rod is connected the taper projection of end and conical socket and cooperates and be plugged on by being arranged on upper connecting rod between lower connecting rod with lower connecting rod.
The driver takes an examination and uses the rigid pile bar, is provided with return awl piece between described upper connecting rod and the lower connecting rod; The upper end of return awl piece is plugged on by taper projection and conical socket cooperation with the upper connecting rod lower end; The lower end of return awl piece is plugged on by taper projection and conical socket cooperation with the lower connecting rod upper end.
The driver takes an examination and uses the rigid pile bar, and the cone angle of described taper projection and conical socket is less than 90 degree greater than zero degree.
The driver takes an examination and uses the rigid pile bar, and the cone angle of described taper projection and conical socket is less than 50 degree greater than 20 degree.
The utility model mechanism assembly has following advantage: 1) compact conformation, and processing cost is low, and with stake bar simple installation, the mounting or dismounting of stake bar are convenient, good looking appearance; 2) return awl piece is guaranteed after the stake bar collision of 15Kg stall rapidly, the stake bar its stall time of tilting after 60 ° less than 20 seconds; Simultaneously also can guarantee can not rock, improve examination efficient at general strong wind king-pile bar.
Description of drawings
Accompanying drawing is a stake bar spring assembly structural representation.
Embodiment
Shown in accompanying drawing.
The utility model driver takes an examination with rigid pile bar spring assembly, the stake bar is made of the body of rod and the spring assembly that is used for connecting-rod body and door frame crossbeam, and spring assembly is bored piece 2 by upper connecting rod 1, lower connecting rod 3 and return and constituted with the spring 4 of upper connecting rod 1, lower connecting rod 3 threaded engagement.Upper connecting rod 1, lower connecting rod 3 are processed with the screw thread that matches with spring respectively, and spinning is in spring 4 two ends; The upper end of return awl piece 2 is plugged on by taper projection and conical socket cooperation with upper connecting rod 1 lower end; The lower end of return awl piece 2 is plugged on by taper projection and conical socket cooperation with lower connecting rod 3 upper ends.The cone angle of taper projection and conical socket is 30 degree.Be plugged on together by awl piece and conical socket cooperation between upper connecting rod 1, lower connecting rod 3 and the return awl piece 2.When the stake bar was rocked by collision, the structure that this awl piece and conical socket cooperate can make a bar spring assembly part make a bar return and static rapidly.
Claims (4)
1. the driver takes an examination with rigid pile bar spring assembly, the stake bar is made of the body of rod and the spring assembly that is used for connecting-rod body and door frame crossbeam, it is characterized in that described spring assembly is linked into an integrated entity upper connecting rod and lower connecting rod two parts by spring, upper connecting rod is connected the taper projection of end and conical socket and cooperates and be plugged on by being arranged on upper connecting rod between lower connecting rod with lower connecting rod.
