Description
Technical field
The utility model relates to a kind of mosquito net frame with rotational expansion fastening joint.
Background technology
The mosquito net of Foldable dismounting formula is comparatively popular at present, and it has advantage easy to carry, that save the space.The tester of this class mosquito net mostly uses expansion link as main support rod, and the expansion link that uses roughly is divided into collapsible and bushing type two classes at present.The adjusting length of folding expansion link generally is several fixed values, promptly expansion link can not be carried out the accent of random length and establish, and also need establish fixture in addition to fix its sub-folding rod at expansion link.Present bushing type expansion link also utilizes peripheral hardware fixture (as snap close etc.) to fix its sub bar, has the defective of using trouble, snap close easily to throw off because of the external force effect; Also have and utilize spring top bead to control length of telescopic bar, same existence can not be regulated the defective of length of telescopic bar arbitrarily.
The utility model content
The technical problems to be solved in the utility model is: can not regulate in order to overcome the present existing tester height of mosquito net that uses of people, or can not carry out after step-less adjustment and the telescopic adjustment defective of fastening poor effect between the tube coupling, the spy provides a kind of mosquito net frame with rotational expansion fastening joint.This mosquito net frame easy accessibility, but back tester height free adjustment is installed, and the tester firm supporting is stable.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of mosquito net frame with rotational expansion fastening joint, it has four telescopic support bars, each telescopic support bar is socketed to form by more piece sleeve pipe correspondence, relatively be divided into extra heavy pipe and tubule according to nest relation between the sleeve pipe, it is fastening by rotational expansion fastening joint after telescopic adjustment that each saves sleeve pipe, described rotational expansion fastening joint is made up of a plinth and an eccentric distensible ring, one end of plinth is fixedlyed connected with an end of tubule, plinth has an eccentric shaft with respect to the central axis off-centre of tubule, and described eccentric distensible ring is sleeved on the above-mentioned eccentric shaft.
The plinth of described rotational expansion fastening joint has a connecting axle that is plugged in the tubule, and fixedlys connected with tubule by this connecting axle.
In order to prevent that eccentric shaft and eccentric distensible ring from " overwinding " phenomenon taking place in revolving the process of expanding, on eccentric distensible ring, have stopper slot, the limited block that matches with stopper slot is set on eccentric shaft.
Be provided with at the two ends of described eccentric shaft and prevent that eccentric distensible ring from axially displaced spacing termination taking place; Another kind prevents that the design that " overwinding " phenomenon takes place for eccentric shaft and eccentric distensible ring from being in revolving the process of expanding: on the eccentric distensible ring with on the above-mentioned spacing termination limited block that matches is being set.
For the ease of making, described plinth is an integral structure.
For convenience eccentric distensible ring cover is loaded onto eccentric shaft, eccentric distensible ring is made open type; Simultaneously for guaranteeing the swelling effect of eccentric distensible ring swelling side, the open side of the inclined to one side near-ring of annular distance of eccentric distensible ring.
Plinth and eccentric distensible ring adopt plastic cement or other to have certain flexible material and make.
The beneficial effects of the utility model are: this mosquito net easy accessibility, but back tester height free adjustment is installed, the tester firm supporting is stable; The telescopic supporting bar structure of tester is simple, easily manufactured, and fastening effect is splendid in the telescopic adjustment process.

Among the figure: 1. 22. eccentric distensible ring 221. stopper slots of telescopic support bar 11. extra heavy pipes 12. tubules 2. rotational expansion fastening joints 21. plinths 211. eccentric shafts 2111. limited blocks 212. connecting axles 213. spacing terminations
The specific embodiment
As shown in Figure 1, a kind of mosquito net frame with rotational expansion fastening joint, have four telescopic support bars 1, as shown in Figure 2, each telescopic support bar is socketed to form by more piece sleeve pipe correspondence, relatively be divided into extra heavy pipe 11 and tubule 12 according to nest relation between the sleeve pipe, it is fastening by rotational expansion fastening joint 2 after telescopic adjustment that each saves sleeve pipe, described rotational expansion fastening joint 2 is made up of a plinth 21 and an eccentric distensible ring 22, one end of plinth 21 is fixedlyed connected with an end of tubule 12, plinth 21 has an eccentric shaft 211 with respect to the central axis off-centre of tubule 12, and described eccentric distensible ring 22 is sleeved on the above-mentioned eccentric shaft 211.
The plinth 21 of rotational expansion fastening joint 2 has a connecting axle 212 that is plugged in the tubule 12, and fixedlys connected with tubule 12 by this connecting axle 212.Be provided with at the two ends of eccentric shaft 211 and prevent that eccentric distensible ring 32 from axially displaced spacing termination 213 taking place.In order to prevent that eccentric shaft 211 and eccentric distensible ring 22 from " overwinding " phenomenon taking place in revolving the process of expanding, on eccentric distensible ring 22, have stopper slot 221, the limited block 2111 that matches with stopper slot 221 is set on eccentric shaft 211.
As another embodiment, prevent that eccentric shaft and eccentric distensible ring from revolving the another kind of design that " overwinding " phenomenon takes place in the process that expands and being: be provided with the limited block that matches with spacing termination 213 on the eccentric distensible ring 22.
For the ease of making, plinth 21 is an integral structure.For convenience eccentric distensible ring 22 covers are loaded onto eccentric shaft 211, eccentric distensible ring 22 is made open type; Simultaneously for guaranteeing the swelling effect of eccentric distensible ring 22 swelling sides, the open side of the inclined to one side near-ring of annular distance of eccentric distensible ring 22.Plinth 21 adopts plastic cement or other to have certain flexible material with eccentric distensible ring 22 and makes.
The swelling Guyuan that revolves of telescopic support bar is managed as follows: when rotating tubule 12, the eccentric shaft 211 that tubule 12 drives rotational expansion fastening joint 2 rotates, thereby eccentric distensible ring 22 is expanded to the inwall of extra heavy pipe 11 gradually by eccentric shaft 211, after rotating 180 °, the pressure of 22 pairs of extra heavy pipe 11 inwalls of eccentric distensible ring reaches maximum, the also corresponding increasing of pressure in this process between eccentric distensible ring 22 and the eccentric shaft 211, by eccentric distensible ring 22, eccentric shaft 211 and extra heavy pipe 11 triangular swellings, realize that expansion link is thick, fastening between the tubule.When need shrink or readjust expansion link, derotation tubule 12, tubule 12 drives eccentric shaft 211 revolutions, eccentric shaft 211 weakens the expansive force to eccentric distensible ring 22 gradually, thereby eccentric distensible ring 22, eccentric shaft 211 and extra heavy pipe 11 triangular tension forces progressively disappear, and expansion link returns to slightly, the tubule state of slippage mutually.
Mosquito net frame easy accessibility of the present utility model, but back tester height free adjustment is installed, and the tester firm supporting is stable; The telescopic supporting bar structure of tester is simple, easily manufactured, and fastening effect is splendid in the telescopic adjustment process.
