Abstract
The invention discloses a trailer coupler of a pump truck. The trailer coupler of the pump truck comprises a female coupler (1) and a male coupler (2). The female coupler (1) is provided with a counter bore (11). A concave spherical surface (111) is arranged at the end part of the counter bore (11). An open slot (12) which is used for being connected with a pump truck frame is arranged at one end of the female coupler (1) which is connected with the pump truck frame. The open slot (12) is provided with a through hole (13). A conical hole (14) which is communicated with the concave spherical surface is arranged at the other end of the female coupler (1). A ball head (21) which is matched with the concave spherical surface (11) is arranged at one end of the male coupler (2). A hinging hole (22) which is connected with a trailer pump is arranged at the other end of the male coupler (2). By adopting the technical scheme, trailer coupler of the pump truck has the advantages that since the two ends of the trailer coupler of the pump truck are connected with the pump truck frame and the trailer pump, the effect of horizontal and vertical free gyration is realized; and since the male coupler and the female coupler are connected through the spherical surface and the ball head, the effect of 360-degree free torsion is realized, the structure is more reasonable, the wear is reduced and the service life of the trailer coupler of the pump truck is improved.
Description
Technical field
The present invention relates to a kind of pump truck accessory, relate in particular to a kind of pump truck and pull button.
Background technology
The holder pump of pump truck and vehicle frame junction need to be used pump truck and be pulled button.The pump truck of prior art is pulled button and is only had freely turning round of horizontal and vertical directions, when walking easily pulls button to pump truck when twisting on the road surface of injustice and causes damage, and serious wear in use procedure, the life-span is short.
Summary of the invention
Goal of the invention: the object of the invention is to for the deficiencies in the prior art, provide a kind of rational in infrastructure, can also pull button by free 360 pump trucks of spending torsion when the horizontal and vertical direction freely returns.
Technical scheme: in order to realize the foregoing invention purpose, the technical solution adopted in the present invention is:.
A kind of pump truck is pulled button, comprise box and pin thread, described box is provided with counterbore, the end of described counterbore is provided with concave spherical surface, the end that described box is connected with vehicle frame is provided with the open slot that is connected for the pump truck vehicle frame, and open slot is provided with through hole, and the other end of described box is provided with the conical surface hole with concave spherical surface UNICOM, described pin thread is provided with the bulb that coordinates with concave spherical surface, and the other end of pin thread is provided with and the hinge hole that asks pump to be connected.
Described pin thread is spring steel.
Beneficial effect: the present invention compared with prior art, its beneficial effect is:
1, the pump truck two ends of pulling button are connected with pump truck vehicle frame, holder pump, realize that the horizontal and vertical direction freely returns, be connected with bulb by sphere between pin thread and box and realize 360 degree free torsion, structure is more reasonable, having reduced wearing and tearing and having improved the service life that pump truck is pulled button;
2, conical surface hole and concave spherical surface UNICOM, bulb coordinates with concave spherical surface, in use, not only can realize the function of 360 degree free torsion between pin thread and box, can also freely swing in chasing after the angle of face, further protect pin thread and box, improve service life;
3, pin thread is spring steel, and good springiness is antitorque, the hardness high abrasion, and be improved service life.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the section-drawing of the A-A of box.
The specific embodiment
Below in conjunction with accompanying drawing, by a most preferred embodiment, technical solution of the present invention is elaborated, but protection scope of the present invention is not limited to described embodiment.
as depicted in figs. 1 and 2, a kind of pump truck is pulled button, comprise box 1 and pin thread 2, described box is provided with counterbore 11, the end of described counterbore 11 is provided with concave spherical surface 111, the end that described box is connected with vehicle frame is provided with the open slot 12 that is connected for the pump truck vehicle frame, open slot is provided with through hole 13, the other end of described box is provided with the conical surface hole 14 with concave spherical surface UNICOM, described pin thread is provided with the bulb 21 that coordinates with concave spherical surface 11, the other end of pin thread is provided with and the hinge hole 22 that asks pump to be connected, described pin thread is spring steel, the open slot 12 of box 1 is hinged on the pump truck vehicle frame by through hole 13, the hinge hole 22 of pin thread 2 is hinged with the holder pump, realization realizes that the horizontal and vertical direction freely returns, the bulb of pin thread coordinates with the concave spherical surface of box, realize that 360 degree reverse, structure is more reasonable, wide adaptability.
Claims (2)
1. a pump truck is pulled button, it is characterized in that: comprise box (1) and pin thread (2), described box is provided with counterbore (11), the end of described counterbore (11) is provided with concave spherical surface (111), the end that described box is connected with vehicle frame is provided with for the open slot (12) that is connected with the pump truck vehicle frame, open slot is provided with through hole (13), the other end of described box is provided with the conical surface hole (14) with concave spherical surface UNICOM, described pin thread is provided with the bulb (21) that coordinates with concave spherical surface (11), the other end of pin thread is provided with and the handing-over hole (22) of asking pump to be connected.
