Description

Anti-dress trailer bulb
Technical field
The utility model relates to a kind of vehicle towed device, particularly a kind of anti-dress trailer bulb.
Background technology
Existing Trailer tool generally is to be made up 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 the tow ball head-shield is firmly got final product with the trailer ball cover.Conventional trailer bulb; Generally comprise and be used for and be located at the threaded shank that is pulled the tapped bore on the vehicle and matches, be used for and trailer ball cover bonded assembly spherical head and the round platform portion between threaded shank and spherical head, threaded shank, round platform portion and spherical head are an integral body.Need not towing vehicle when traction, making on its surface attachment foreign matter in the external environment or be corroded for preventing that the tow ball head length phase is exposed to, people can be covered up the trailer bulb usually; But after taking off the trailer bulb, be located at and be pulled the tapped bore that is used for trailer-erector bulb on the vehicle and will be exposed to external environment, the time has foreign matter such as sand and dust and piles up in long tapped bore; Therefore; Before the trailer bulb was installed to the tapped bore place, people need dispose the foreign matter that is deposited in the tapped bore earlier at every turn, and tapped bore is generally all less; This makes the foreign matter of concealing between thread be very difficult to cleaning, is not easy to the installation of trailer bulb.
The utility model content
The technical matters that the utility model will solve is a kind of cleaning work that can make things convenient for greatly before using to be provided, thereby to make things convenient for the anti-dress trailer bulb of installing.
For solving the problems of the technologies described above; The utility model provides a kind of anti-dress trailer bulb of following structure: comprise being used for and trailer ball cover bonded assembly spherical head and an end and spherical head bonded assembly round platform portion; Wherein, The round platform portion other end is connected with a pipe link, and spherical head, round platform portion and pipe link are an integral body, and pipe link is provided with negative thread.
The described anti-dress trailer bulb of the utility model, wherein, pipe link is provided with the pin-and-hole that communicates with negative thread.
After adopting said structure, compared with prior art, the utlity model has following advantage: because the anti-trailer bulb of adorning of the utility model has replaced the threaded shank in the prior art trailer bulb with the pipe link that is provided with negative thread; Therefore; People only need a screw rod that matches with pipe link is set on the vehicle can the anti-trailer bulb of adorning of the utility model is installed to and is pulled on the vehicle being pulled, and undoubted, than tapped bore; Screw rod not only is not easy to foreign matter and piles up; But also be easier to clear up the foreign matter of concealing between thread, in addition, because the anti-trailer bulb of adorning of the utility model can be covered up when not using usually; Therefore the negative thread place of its pipe link also is difficult for piling up foreign matter; Comprehensively above-mentioned, the utility model is counter adorns the cleaning work before the trailer bulb can make things convenient for it to use greatly, and it can be installed to more easily be pulled on the vehicle.
The utility model is counter to be adorned the trailer bulb and in the effect that the pin-and-hole that communicates with negative thread is set on the pipe link is: people can be arranged on be pulled on the vehicle and with screw rod that pipe link matches on offer a through hole that matches with this pin-and-hole; When the utility model is counter adorn the tow ball epicranium be installed to be pulled on the vehicle after; People just can be inserted in pin in pin-and-hole and the through hole, thereby can prevent effectively that pipe link and screw rod from relatively rotating and break away from each other.
Description of drawings
Fig. 1 is the counter perspective view of adorning the trailer bulb of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the anti-trailer bulb of adorning of the utility model is done further to specify.
As shown in Figure 1; In this specific embodiment; The utility model the utility model is counter adorn the trailer bulb comprise be used for trailer ball cover bonded assembly spherical head 1, be used for be arranged on be pulled the pipe link 3 that the screw rod on the vehicle matches and be connected spherical head 1 and pipe link 3 between round platform portion 2; Spherical head 1, round platform portion 2 and pipe link 3 are an integral body, and pipe link 3 is provided with the pin-and-hole 5 that negative thread 4 and being used for of communicating with negative thread 4 match with through hole on being opened in screw rod.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection domain of the utility model claims.
