Description

The rotatable Christmas tree foot rest that closes up of cross-garnet butt formula

The utility model relates to and a kind ofly is used for apparatus or the board or the frame of the conduct supporting of goods on it, especially can rotate and folding Christmas tree foot rest.

Support bigger Christmas tree, have enough big Area of bearing could keep its stability, the most of steel plate that adopts of existing large-scale Christmas tree foot rest welds or monoblock cast.Its weight and volume is all bigger.Manufacturing cost is relative with freight higher, and these problems directly influence to be used and competitiveness of product.

The purpose of this utility model is to propose the rotatable Christmas tree foot rest that collapses of a kind of cross-garnet butt formula, and it is big that it has an Area of bearing, can rotate the characteristics of transporting, occupying little space of closing up conveniently again.

Utility model is achieved in that the rotatable Christmas tree foot rest that closes up of a kind of cross-garnet butt formula, comprise supporting leg 3,4, lacing wire 5,6, central tube 7, it is characterized in that: the upper end of central tube 7 is provided with the draw 71, the lower end of central tube is provided with down the draw 72, the last sleeve pipe 1 that tube wall is provided with screw slightly is shorter than the draw 71 with the last draw 71 rotatable covers merging, setting of casing 8 slightly is shorter than down the draw 72 with the following draw 72 rotatable covers merging that tube wall is provided with concave point, supporting leg 4 symmetries are fixed in two sides of central tube 7, symmetrically arranged lacing wire 6 one ends are fixed in the lower end of central tube 7, and end is fixed in the bend pipe side of supporting leg 4 in addition; Supporting leg 3 symmetries are fixed on the sleeve pipe 1, and symmetrically arranged lacing wire 5 one ends are fixed in the bend pipe side of supporting leg 3, and end is fixed on the setting of casing 8 in addition; On the last cover tube wall three screws 11 are set, can run through eyebolt 2 when three Chang Yuan holes 711 of described screw 11 and last draw setting are involutory state.The following draw 72 tube walls are provided with three concave points 721.First group of supporting leg is for being fixed in symmetrically arranged supporting leg 4 and lacing wire 6 on the central tube 7; Second group of supporting leg is to be fixed in symmetrically arranged supporting leg 3 and an end on the sleeve pipe 1 to be fixed on the setting of casing 8 lacing wire 5 that end in addition is fixed in supporting leg 3 bend pipe sides; The supporting leg bending is Type.The draw 71 cover exposed parts behind the sleeve pipe 1 that closes on the central tube, the exposed parts two places outer walls thickening behind the following draw 72 fit setting of casings 8 makes respectively to cooperate the contact position endways with upper and lower sleeve pipe 1,8.

The utility model is by the supporting leg of four welded pipe bend pipes moulding, and to be symmetrically welded at that central tube and upper and lower cover form with the central tube be the cross of axis, the cross that supporting leg forms can be around the central tube rotation, and just supporting leg closes up the very thin volume of Cheng Yizhan, conveniently transports and closes up foot rest.In light weight, simple in structure, and processing ease.

Now further narrate structure of the present utility model in conjunction with the accompanying drawings:

Referring to Fig. 1-6: the utility model by central tube 7, go up sleeve pipe 1, setting of casing 8, supporting leg 3,4, lacing wire 5,6, eyebolt 2, footmuff 9 and be combined to form.The two ends draw of central tube 7, the draw 71 and last sleeve pipe 1 fit on it, last casing length is shorter than the length of the draw, the following draw 72 and setting of casing 8 fits of central tube, the cased length that is shorter in length than down the draw.The central tube upper end draw 71 suitable for reading is provided with three slotted holes 711, and three concave points 721 of the central tube lower end draw 72 end punching presses make the internal diameter of this concave point place draw become little than draw place.External diameter unanimity after central tube 7, last sleeve pipe 1, setting of casing 8 fits.The corresponding position that slotted hole 711 is set at the last sleeve pipe 1 upper end central tube draw is provided with three screws 11.Supporting leg 3,4 all is with thinner welded pipe bending Shape.Referring to first group of supporting leg of Fig. 3, two supporting legs 4 of draw part bilateral symmetry welding not in the centre of central tube 7.And the lacing wire 6 that connects supporting leg 4 in the bottom of central tube 7, the other end of lacing wire 6 is welded on the lower end of supporting leg 4 respectively, second group of supporting leg welds two supporting legs 3 in the bilateral symmetry of last sleeve pipe 1, and the lacing wire 5 of welding supporting leg in the bottom of setting of casing 8, the other end of lacing wire 5 is welded on the lower end of two supporting legs 3 respectively, as shown in Figure 4.First group of supporting leg and second group of supporting leg can rotate around central tube 7, when supporting leg 3 and supporting leg 4 are vertical mutually, slotted hole 711 central lines at the draw 71 places on the center line of three screws 11 on the last sleeve pipe 1 and the central tube can be inserted eyebolt 2 and twist spiral shell.When the front end of eyebolt 2 entered three slotted holes 711 on the central tube 7, the upright position between the supporting leg 3,4 was fixed, and was inserted into to continue to tighten eyebolt 2 behind the Christmas tree trunk again trunk is fixed.When Christmas, trunk inserted central tube 7 because central tube is shorter, at following three concave points 721 of the draw 72 places punching press, make trunk can not pass central tube concave point 721, play the effect of supporting trunk, come off from the central tube draw for fear of upper and lower sleeve pipe, wall thickness made sleeve pipe 1, setting of casing 8 can only rotate in the draw and can not come off outside the outer most edge of the draw 71 and the following draw 72 increased a bit with spot welding slightly on central tube.Each supporting leg lands to hold and is with plastics footmuff 9 to increase frictional force.Three eyebolts 2 do not insert sleeve pipe 1 in the transportation and storage process, foot rest is and closes up state, in use the foot rest that closes up state is opened to make and be 90 ° of arrangements between four supporting legs, allow three Chang Yuan hole 711 central lines on three screws 11 and the central tube 7 of sleeve pipe simultaneously, be screwed into the eyebolt 2 supreme draw 71 inner wall edges, then the Christmas tree trunk is inserted central tube 7, and confirms that trunk fallen three concave point 721 places, continue again to tighten eyebolt 2 Christmas trunk lock.The Christmas tree foot rest that this moment, the utility model limited is firm is supporting a big Christmas tree.
