Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 4, the connector in the present embodiment includes a base body 1, and the base body 1 has a first mounting groove 11, a second mounting groove 12, a third mounting groove 13, a fourth mounting groove 14, and a fifth mounting groove 15 therein, to which the stay bar 2 can be mounted. This base member 1 can be a block, and inside this first mounting groove 11, second mounting groove 12, third mounting groove 13, fourth mounting groove 14 and fifth mounting groove 15 of shaping respectively, and this base member 1 also can be for the cylinder body that the axial that corresponds each mounting groove outwards extends one and has the cell body of outside open-ended respectively and connect and the part that forms. In the present embodiment, the latter base body 1 is used, and the base body 1 may be integrally formed by a mold.

Wherein first mounting groove 11, second mounting groove 12 extend to the horizontal plane tilt up, have contained angle and bilateral symmetry between the central axis of first mounting groove 11, second mounting groove 12. The third mounting groove 13 and the fourth mounting groove 14 extend downwards relative to the horizontal plane, and an included angle is formed between the central axes of the third mounting groove 13 and the fourth mounting groove 14 and the third mounting groove and the fourth mounting groove are symmetrical left and right. And in order to ensure the supporting stability after the stay bar 2 is connected, the central axes of the first mounting groove 11, the second mounting groove 12, the third mounting groove 13 and the fourth mounting groove 14 are on the same plane. The included angle between the central axes of the first mounting groove 11 and the second mounting groove 12 is an obtuse angle. The included angle between the central axes of the third mounting groove 13 and the fourth mounting groove 14 is an obtuse angle. The included angle between the central axes of the first mounting groove 11 and the second mounting groove 12 is equal to the included angle between the central axes of the third mounting groove 13 and the fourth mounting groove 14. Therefore, the central connecting lines of the first mounting groove 11, the second mounting groove 12, the third mounting groove 13 and the fourth mounting groove 14 can form an X shape.

The fifth mounting groove 15 extends horizontally forwards and/or backwards, that is, the axial center line of the fifth mounting groove 15 is perpendicular to the axial center lines of the first mounting groove 11, the second mounting groove 12, the third mounting groove 13 and the fourth mounting groove 14. The extending direction of the fifth mounting groove 15 is specifically set as required, if the connecting piece is applied to the middle position, the two sides of the connecting piece are respectively required to be connected with the support rods 2 to be connected with other connecting pieces in a supporting manner, and the fifth mounting groove 15 is horizontally extended forwards and backwards in the base body 1. If the connecting element is used in the end position, it is only necessary to provide this fifth mounting groove 15 extending horizontally forwards or backwards in the base body 1.

In addition, vaulting pole 2 is when installing to each mounting groove, because vaulting pole 2 needs carry out the fastness of tight fit in order to guarantee the connection with the mounting groove, consequently can compress the space between vaulting pole 2 and the mounting groove bottom when vaulting pole 2 pegs graft in to the mounting groove and form certain atmospheric pressure, thereby make vaulting pole 2 can't insert the bottom to the mounting groove, in order to avoid this condition, be corresponding to first mounting groove 11 in the base member 1, second mounting groove 12, third mounting groove 13, all be provided with cavity 18 outside the bottom of fourth mounting groove 14, first mounting groove 11, second mounting groove 12, third mounting groove 13, the bottom of fourth mounting groove 14 all is provided with the connecting hole 16 that is linked together with the cavity that corresponds. Therefore, when the support rod is used, the situation that the support rod 2 is not inserted in the installation groove in place can be effectively avoided.

In addition, in order to improve the strength of the connector, reinforcing ribs 17 are connected between the outer surface of the fifth mounting groove 15 and the outer surfaces of the first mounting groove 11, the second mounting groove 12, the third mounting groove 13 and the fourth mounting groove 14.

The use method of the connecting piece on the leisure bed comprises the following steps: one coupling member having two fifth mounting grooves 15 and two coupling members having one fifth mounting groove 15 are used. For convenience of description, the coupling member having two fifth mounting grooves 15 is referred to as a first coupling member, and the coupling member having one fifth mounting groove 15 is referred to as a second coupling member. Two second connecting pieces are respectively arranged at two sides of the first connecting piece, the fifth mounting grooves 15 on the second connecting pieces are respectively arranged facing the first connecting pieces, one support rod 2 is horizontally inserted into the two fifth mounting grooves 15 of the first connecting piece respectively, the outer ends of the two support rods 2 are inserted into the fifth mounting grooves 15 of the first connecting piece, so that the two support rods 2 are utilized to connect the three connecting pieces together, and the total length of the formed connecting pieces is basically consistent with the total length of the leisure bed. Then, the stay bars 2 are respectively inserted into the first mounting groove 11, the second mounting groove 12, the third mounting groove 13 and the fourth mounting groove 14 of each connecting piece, and the stay bars 2 inserted into the third mounting groove 13 and the fourth mounting groove 14 of the three connecting pieces can be supported on the ground, thereby forming ground support. The upper ends of the support rods 2 inserted into the first mounting groove 11 and the second mounting groove 12 of the three connecting pieces are respectively connected with a fastener 3 which can be connected with the bed surface. Both sides of the width direction of the bed surface are provided with a stay bar 2, and the two stay bars 2 are respectively buckled on the buckling pieces 3 at both sides, so that the leisure bed is assembled.

Therefore, when the leisure bed using the connecting piece is assembled, the connecting piece is few, the number of parts for assembling is small, the connecting speed is high, the connecting mode is simple, the operation is easy, the connecting piece is not in contact with the ground, the service life is long, the stability in the using process is good, and the service life is long.
