Abstract

The utility model relates to a kind of adjustable fork, the conduction axis that it comprises a base, be arranged on the prong in base, the setscrew nut that be fixedly connected with relative to described prong and controlled described setscrew nut, wherein said prong is two and arranges in pairs, the corresponding setscrew nut hand of spiral of described a pair of prong is contrary, described conduction axis is symmetrical, and is provided with described nut the positive and reverse return screw thread engaging.The relative position that this utility model device is controlled prong by conduction axis simultaneously guarantees that this can not be partial to a side of fork truck to prong, and can regulate prong relative distance according to the size of goods, make it possible to transport more reposefully goods.

Description

Adjustable fork

Technical field

The utility model, about a kind of mechanical field crane tool, refers in particular to the adjustable fork being arranged on fork truck.

Background technology

The prior art relevant to the utility model refers in No. 201121113 patent of Chinese utility model of on 09 24th, 2008 bulletins, this patent has disclosed a kind of fork truck, this fork truck has adjustable four tooth forks, the bottom of crotch is provided with plinth, prong is installed on plinth, and be arranged on fork shaft by sliding sleeve, be respectively equipped with crotch adapter plate in the both sides of crotch, be provided with mounting hole thereon, the two ends of fork shaft are fixed on crotch by pressing plate, are convenient to like this dismounting and the use of fork.But the fork structure of four teeth itself has just caused the waste of resource, when its tooth head regulates in addition, can not ensure that its relative center of tooth head is in fork centre, thereby easily cause fork goods that the situation to lopsidedness occurs in transportation.

Therefore, be necessary to provide one to there is structure improved fork truck crotch, to overcome above-mentioned defect.

Utility model content

The purpose of this utility model is to provide a kind of fork truck fork that can free adjustment prong relative distance.

For achieving the above object, the utility model adopts following technical scheme:

A kind of adjustable fork, the conduction axis that it comprises a base, be arranged on the prong in base, the setscrew nut that be fixedly connected with relative to described prong and controlled described setscrew nut, wherein said prong is two and arranges in pairs, it is described that this is contrary to the corresponding setscrew nut hand of spiral of prong, described conduction axis is symmetrical, and is provided with described nut the positive and reverse return screw thread engaging.

Further, described conduction axis is controlled the right spinning in and out of described nut simultaneously.

Further, face centered by the mirror symmetry planes of the left and right wheels of fork truck, described prong is about described longitudinal plane of symmetry symmetry.

Further, described fork is also provided with a control apparatus, and conduction axis rotation can be controlled or suppress to this control apparatus, to control the relative position of described prong.

Compared with prior art, the utility model device has following beneficial effect: the relative position of simultaneously controlling prong by conduction axis guarantees that this can not be partial to a side of fork truck to prong, and can regulate prong relative distance according to the size of goods, make it possible to transport more reposefully goods, and easy and simple to handle.

Detailed description of the invention

Please refer to shown in Fig. 1 and Fig. 4 the utility model electronic adjustable fork 1, the conduction axis 4 of comprise a plinth 2, be arranged on the prong 3 in described base 2, the setscrew nut that be fixedly connected with 5 relative to described prong 3 and being controlled described setscrew nut 5.

Described prong 3 is two and is arranged in pairs in described base 2.If face centered by the mirror symmetry planes of the both sides wheel (not shown) of fork truck (not shown), described prong 3 is about described longitudinal plane of symmetry symmetry.

Please, with further reference to shown in Fig. 2, Fig. 3, the nut that be fixedly connected with relative to described prong 3 is to 5a, and 5b is respectively equipped with the negative thread that hand of spiral is contrary.Described nut is to 5a, and 5b is sheathed on described conduction axis 4 both sides, please refer to shown in Fig. 1, and these conduction axis 4 two ends are also provided with helicitic texture, and described helicitic texture and described nut are to 5a, and the negative thread of 5b engages.Described fork is also provided with a control apparatus (not shown), and this control apparatus can be controlled or suppress conduction axis 4 and rotate, to control the relative position of described prong 3.

Please refer to shown in Fig. 1 to Fig. 5, in the time that described conduction axis 4 rotates, nut 5a and nut 5b are because hand of spiral is contrary, so nut 5a and nut 5b counter motion, and only there is the difference of hand of spiral in nut 5a and nut 5b, so the stepping length of nut 5a and nut 5b is consistent, nut 5a and nut 5b can be consistent to the distance of aforementioned longitudinal plane of symmetry like this.Same, the fixing prong 3 of nut 5 also can, in adjusting prong spacing, remain that the distance of described longitudinal plane of symmetry is consistent relatively.In the time of fork truck real work, staff can be according to the profile of goods, prong 3 spacings are adjusted, to keep the stability of goods in transport process, and the relative longitudinal plane of symmetry symmetry of prong 3, so under the prerequisite of proper operation, the center of gravity of goods can be too partial to a certain prong 3, has strengthened equally the stability of goods in transport process.

In sum, these are only preferred embodiment of the present utility model, should not limit scope of the present utility model with this, be that every simple equivalence of doing according to the utility model claims and utility model description changes and modifies, all should still belong in the scope that the utility model patent contains.
