Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of load-supporting device, particularly relates to the load-supporting device that a kind of setting range is wider.
Background technology
At present, for the goods in freight container or box-body truck, use common rope cannot reach the object of fixing transporting cargo, in order to address this problem, people have devised various instrument, and load-supporting device is exactly wherein a kind of.Load-supporting device is made up of inner and outer tubes, and on inner pipe, outer tube is hinged with handle, and the inner of handle has ratchet to outer tube part cover, interior pipe has some teeth along its axial array.Just handle can be fixed after the ratchet embedding teeth of handle, making interior pipe and outer tube fix both can not shrink again.
As the lockout mechanism [patent No.: 200920117212.2 of a kind of load-supporting device that the applicant once proposed; Notification number: CN201423974Y], comprise interior pipe and part cover outer tube on inner pipe, teeth are axially arranged with along it outside interior pipe, outer tube is hinged with handle, the inner of handle has the engaging tooth that can be embedded in teeth place, be provided with locations between outer tube and handle, when handle the inner is embedded in teeth place, handle can be located by locations.The load-supporting device of this lockout mechanism application is exactly utilize handle to control interior relative position of managing between outer tube according to the height in compartment or length, and load-supporting device is elongated or shortened.Relative position between interior pipe and outer tube is then undertaken regulating by the teeth on handle and interior pipe, during adjustment, teeth on the engaging tooth of handle the inner and interior pipe are separated from each other, interior pipe can move relative to outer tube, after interior pipe is moved to correct position, in the teeth that turning handle makes the engaging tooth of handle the inner clamp on interior pipe, then utilize locations to be located by handle, engage therefore interior pipe because handle is inner with the teeth on interior pipe and interfix with outer tube.
Teeth on interior pipe are all adopt impact style directly shaping at interior pipe outer surface, but the restriction of inner pipe wall, general all more shallow in the degree of depth of the teeth of interior pipe outer surface punching press formation, in the teeth of pipe in the engaging tooth of handle the inner embeds and when being meshed with it, because the degree of depth of teeth is more shallow, the engaging tooth of handle the inner is caused easily to come off out from teeth, thus make support goods time interior pipe and outer tube between connection firm not, stability is not high enough, easily has influence on the using function of load-supporting device.
Summary of the invention
The purpose of this utility model is the problems referred to above existed for prior art, propose a kind of ensure to support goods setting range while can improve again the load-supporting device of interior pipe and outer tube Joint strenght.
The purpose of this utility model realizes by following technical proposal: a kind of load-supporting device, comprise outer tube and be partly positioned at the pipe of outer tube, described interior pipe is protruding from the outer end of outer tube, outer tube is hinged with handle and handle the inner is provided with ratchet, it is characterized in that, described interior pipe outer end place is fixed with tooth bar by fastener, described tooth bar is axially arranged with some teeth that can be meshed with ratchet along it, extension tube is arranged with outside described outer tube, described extension tube sidepiece has some just right adjustment holes along its axial array, the inner sidepiece correspondence of described outer tube is provided with just right knock hole, described outer tube be provided with the locations both being connected when knock hole faces with one of them adjustment hole or making both to be separated between extension tube.
Extension tube is enclosed within outside outer tube, initial condition, and most of outer tube is positioned at extension tube, and adjustment hole corresponding with current location for the knock hole on outer tube is connected by locations.During adjustment, first by locations, outer tube and extension tube are separated, then extension tube is stretched to suitable position relative to outer tube, when recycling locations makes the knock hole on outer tube therewith, in extension tube, corresponding adjustment hole is connected, outer tube and extension tube are retightened, and finally recycling handle regulates the relative length between outer tube and interior pipe.
This load-supporting device is by connecting the mode of tooth bar outward at interior pipe, because teeth are arranged on tooth bar, what therefore the degree of depth of teeth can be arranged is darker, thus the ratchet of handle the inner can be engaged more securely with the teeth on tooth bar, not easily departs from.But because the length of tooth bar is general shorter, therefore ensure that this load-supporting device has original setting range by extension tube.
In above-mentioned load-supporting device, the side relative with interior pipe, described tooth bar outer end has in block location division of protruding, and the bottom of described location division has the locating surface fitted with interior tube side part, and described fastener passes location division and interior pipe.
Tooth bar is fixed through pipe in location division and interior Guan Eryu by fastener, in order to prevent tooth bar from rotating relative to interior pipe around fastener, therefore arranging locating surface in the bottom of location division, being affixed the rotation of incompatible elimination tooth bar by locating surface and interior tube side part.
In above-mentioned load-supporting device, described interior pipe is pipe, and described locating surface is circular arc.
In above-mentioned load-supporting device, as another kind of technical scheme, described interior pipe is that square, described locating surface takes the shape of the letter U.Adopt square tube or pipe to be common mode, when interior pipe be pipe or square tube time, the joint face bottom location division is arranged to arc or U-shaped, and such joint face just can fit with the sidepiece of interior pipe, thus tooth bar can not be swung relative to interior pipe.
In above-mentioned load-supporting device, as another kind of technical scheme, the side relative with interior pipe, described tooth bar outer end has the sleeve with interior tube side part mating shapes, and described sleeve is placed on interior pipe, and described fastener is through sleeve and interior pipe.Tooth bar, by the outside of jacket casing at interior pipe, utilizes fastener sleeve and outer tube to be fixed together, and prevents tooth bar to rotate relative to interior pipe.
In above-mentioned load-supporting device, described interior pipe is pipe, and described sleeve cylindrically.
