Abstract
The utility model discloses a trailer ball head convenient to hold. The technical scheme is that the trailer ball head convenient to hold comprises a rod portion used for being connected with a vehicle chassis and a ball head used for clamping a trailer arm. A cone portion is placed between the rod portion and the ball head. The diameter of the cone portion gradually increases along the direction of the rod portion from the direction of the ball head. Due to the adoption of the trailer ball head convenient to hold, a round table portion of a conventional trailer ball body is changed into the cone portion, and the diameter of the cone portion gradually increases along the direction of the rod portion from the direction of the ball head, and therefore when installing the trailer ball head, operating personnel hold the trailer ball head conveniently, and accordingly the trailer ball head and the vehicle chassis can be fast and conveniently installed.
Description
Technical field
The utility model relates to a kind of vehicle towed device, and more particularly, it relates to a kind of trailer bulb of being convenient to control.
Background technology
Existing Trailer tool generally is to be made of trailer bulb, tow arm and trailer ball cover three parts that are connected on the tow arm, tow arm is installed on the towing vehicle usually, the trailer bulb then is installed in usually and pulls, fault vehicle etc. is pulled on the vehicle, when needs with towing vehicle when being pulled vehicle and being connected, only need with a trailer ball cover tow ball head-shield is firmly got final product.
Conventional trailer bulb, generally comprise for be located at the bar portion that is pulled the tapped bore on the vehicle and matches, be used for the spherical head that is connected with the trailer ball cover and the round platform portion between bar portion and spherical head, round platform portion is commonly used to be connected with handle, and bar portion, round platform portion and spherical head are an integral body.
Because above-mentioned bar portion, round platform portion and spherical head are rotary structure, in other words, bar portion, round platform portion and spherical head periphery wall are the smooth side that is unfavorable for tool operations such as spanner, therefore, when the trailer-erector bulb of assembly crewman, generally can only bar portion be screwed in the tapped bore on the vehicle chassis with hand-tight round platform portion or the spherical head of holding, the size of round platform portion axial direction is less, be the thinner thickness of round platform portion, be unfavorable for operating personal rotation dominated by hand, assembling is trouble.
The utility model content
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of trailer bulb of being convenient to control, so that trailer bulb and vehicle chassis can be realized convenient the installation.
For achieving the above object, the utility model provides following technical scheme: a kind of trailer bulb of being convenient to control, the spherical head that comprises for the bar portion that is connected with vehicle chassis and be used for blocking for tow arm, be provided with cone part between described bar portion and the ball head, the direction diameter of described cone part from the direction of spherical head along bar portion increases gradually.
By adopting technique scheme, make the trailer spheroid round platform portion of routine into cone part, the direction diameter of cone part from the direction of spherical head along bar portion increases gradually, this is convenient to operating personal and when trailer-erector bulb the trailer bulb is gripped, thereby makes trailer bulb and vehicle chassis can realize convenient the installation.
The utility model further is set to: be provided with interconnecting gangway between described spherical head and the cone part, described spherical head, interconnecting gangway, cone part and bar portion are wholely set successively, and the axial dimension of spherical head, cone part and bar portion is elongated successively.
By adopting technique scheme, make the structure of trailer spheroid specialize, whole spheroid is wholely set, and need not the trailer bulb self is assembled, and each spot size increases gradually, improves the reasonableness of structure.
The utility model further is set to: described interconnecting gangway is cylindric, the junction of interconnecting gangway and spherical head is planar for the arc of depression, the diameter of corresponding interconnecting gangway one end of described cone part is identical with the diameter of interconnecting gangway, and the diameter of the corresponding bar of described cone part portion one end is identical with the diameter of bar portion.
By adopting technique scheme, the connection structure of interconnecting gangway and spherical head can strengthen the intensity that both connect, and the connection mode at each position has improved the aesthetics of trailer bulb.
Description of drawings
The structural representation of the trailer bulb embodiment that Fig. 1 is convenient to control for the utility model.
The specific embodiment
The trailer bulb embodiment of being convenient to control with reference to the utility model of Fig. 1 is described further.
A kind of trailer bulb of being convenient to control, the spherical head 2 that comprises for the bar portion 1 that is connected with vehicle chassis and be used for blocking for tow arm, be provided with cone part 3 between described bar portion 1 and the ball head, the direction diameter of described cone part 3 from the direction of spherical head 2 along bar portion 1 increases gradually.
By adopting technique scheme, make the trailer spheroid round platform portion of routine into cone part 3, the direction diameter of cone part 3 from the direction of spherical head 2 along bar portion 1 increases gradually, this is convenient to operating personal and when trailer-erector bulb the trailer bulb is gripped, thereby makes trailer bulb and vehicle chassis can realize convenient the installation.
Be provided with interconnecting gangway 4 between described spherical head 2 and the cone part 3, described spherical head 2, interconnecting gangway 4, cone part 3 and bar portion 1 are wholely set successively, and the axial dimension of spherical head 2, cone part 3 and bar portion 1 is elongated successively.
By adopting technique scheme, make the structure of trailer spheroid specialize, whole spheroid is wholely set, and need not the trailer bulb self is assembled, and each spot size increases gradually, improves the reasonableness of structure.
Described interconnecting gangway 4 is cylindric, interconnecting gangway 4 is planar for the arc of depression with the junction of spherical head 2, the diameter of described cone part 3 corresponding interconnecting gangway 4 one ends is identical with the diameter of interconnecting gangway 4, and the diameter of the corresponding bar of described cone part 3 portion 1 one ends is identical with the diameter of bar portion 1.
By adopting technique scheme, the connection structure of interconnecting gangway 4 and spherical head 2 can strengthen the intensity that both connect, and the connection mode at each position has improved the aesthetics of trailer bulb.
