A kind of tensioning apparatus

Technical field

The utility model relates to a kind of tensioning apparatus, is specially adapted to use on the paulin frame, to improve the firm and reliable connection between paulin hack lever body.

Background technology

Tent generally includes in design: a support is located at a ground paulin frame and a tarpaulin that is overlapped on the paulin frame, and wherein the paulin frame is to be connected and composed by some montants, cross bar and brace.And in order to improve the rigidity that is connected between montant and cross bar, the paulin frame can firmly be supportted be located on the ground, known mode is that support bar is established in oblique support between cross bar and montant.This mode is no doubt feasible, but because the bad adjusting of support bar makes troubles for the assembling of paulin frame, is easy to generate fork, rocks unstable phenomenon.Therefore the paulin frame firmly and simply being set up on the ground, is in the general tent design problem to be solved to be arranged.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of can more convenient, firmly the paulin frame support to be located at ground tensioning apparatus at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this tensioning apparatus, mainly comprise a rotatable adapter sleeve, be arranged with shoulder hole with the length center in the adapter sleeve, be respectively equipped with left and right screw thread in the hole, an one left-handed bolt and a dextrorotation bolt are connected in two of adapter sleeve respectively, are respectively equipped with the connector that connects usefulness on two bolts.

Described connector can be a hook that connects with the bolt end hook, and hook is provided with the rivet hole that is connected and fixed usefulness with pole.One end face of described two bolts all is processed into the inclined-plane of certain angle, is shaped on the ladder U-shaped hook groove of an opening on the inclined-plane respectively; Described hook can be made one and have the hook spare that big or small newel post platform, cross section are " worker " shape, wherein the small end pylon hooks in the U-shaped hook groove of adapter sleeve, the profile of big newel post platform and the inclined-plane of bolt are suitable, and upper and lower surface matches with the inclined-plane of contacted surface of pole and bolt respectively.

Described connector can also be one to have the cylindrical drag hook of a plurality of steps, and an end face of described two bolts all adds angled inclined-plane, is shaped on a jack on the inclined-plane respectively.

The profile of described adapter sleeve can be circular, square or by four circular arc limits constitute similar square.

Compared with prior art, advantage of the present utility model is: as long as the utility model is by the cover that is rotatably connected, but with regard to the tensioning of implement device or unclamp simple in structure, good looking appearance, easy to operate; Apply on the tent, it is firm that column is connected with crossbeam, and help regulating the steady of each column, can not rock, diverge, and can easily, easily tent firmly be supportted to be located on the ground.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Embodiment one: specifically as shown in Figure 1, the utility model tensioning apparatus mainly comprises an adapter sleeve 1, one a left-handed bolt 2a and a dextrorotation bolt 2b.

The profile of described adapter sleeve 1 is similar square (as shown in Figure 2) that is made of four circular arc limits, the inside of adapter sleeve 1 is processed with the centrosymmetric shoulder hole 11 of length with cover, wherein the hole is processed with left and right hand thread respectively in adjacent with two stomidiums, to connect with left and

right bolt

2a, 2b respectively.

Described left and

right bolt

2a, 2b except the rotation direction of screw thread on the contrary, shape is identical, is a stepped cylinder.One end face of two bolts all is processed into the inclined-plane 21 of certain angle, coincideing with the contact surface of crossbeam 4 that is connected or column 5 respectively.On inclined-plane 21, be shaped on 22 (as shown in Figure 3) of ladder U-shaped hook groove of an opening respectively, in the hook groove 22 respectively hook be provided with one the hook 3.Described left and

right bolt

2a, 2b are connected in two of adapter sleeve 1 respectively, and precession or outwards back-out inwards simultaneously under the turning effort of adapter sleeve is so the two articles that drive is connected with two bolts is drawn over to one's side or diverged.

Described hook 3 is one to have the hook spare that big or small newel post platform, cross section are " worker " shape, wherein the small end pylon hooks in the U-shaped hook groove 22 of adapter sleeve, the profile of big newel post platform and the inclined-plane 21 of bolt are suitable, can make ellipse roughly, the upper and lower surface of big newel post platform respectively with the inclined-plane of crossbeam or contacted surface of column and bolt match (combining Fig. 4, shown in Figure 5).Also be provided with on 3 at hook and be used for the rivet hole that is connected and fixed with crossbeam 4 or column 5.

With reference to Fig. 4, shown in Figure 8, when the utility model was applied on the tent, this device was contained between the crossbeam and column on the paulin, had not only solved the support and connection between crossbeam and column but also helped regulating each column by this device so steadily to stay on the ground.During assembling, earlier two hooks, 3 usefulness rivets 6 are separately fixed at the corresponding position of crossbeam 4 or column 5, hook respectively then in the U-shaped hook groove 22 of two bolt heads, hold adapter sleeve 1 again, counterclockwise or clockwise direction rotates, to making crossbeam 4 and column 5 be in best connection status.

Embodiment two: as shown in Figure 6, except connector and embodiment one were different, structure was basic identical with embodiment one.Connector is one to have the cylindrical drag hook 7 of a plurality of steps, all is processed with the jack that can insert for drag hook accordingly on the inclined-plane of left and right bolt.And on the crossbeam 4 of paulin and column 5, be processed with the Pear-Shaped hole 8 that can hook for drag hook.

The utility model can also have other constructional variant, and not break away from protection domain of the present utility model except the structure shown in above-mentioned two embodiment.Except similar square as shown in the figure, can also do circular, square etc. as the profile of adapter sleeve; One end inclined-plane of left and right bolt also can be processed into circular arc, is used for columniform crossbeam or column suitable; Connector also can adopt the connector of other structural shape, does some adaptive changes according to the end of the left and right bolt of connector.
