Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in the scope of the claims of the utility model.

Embodiment 1, as shown in Figure 1, containing supporter 1 and linking arm 2, supporter 1 and human contact are supplied to human body One support force appropriate, supporter 1 are a upperseat concepts, can be the backboard with back contact, are also possible to connect with waist The waist support of touching.

In the present case, in order to improve supporter 1 to the support force of human body and reinforce laminating degree, so that supporter 1 and company Connect 2 active link of arm, it can in the horizontal direction or the rotation of level of approximation direction between two components.

As shown in figure 3, supporter 1 includes main support chip 16, main support chip 16 is equipped with multiple through-holes 14 and increases gas permeability. Connection sheet 11 there are two setting on main support chip 16, is the upper connection sheet 111 and the lower connection of lower position of top position respectively Piece 112.

It include supporter casting die 3 as shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 5, supporter casting die 3 is mounted on the sliding groove in Fig. 3 On 13, wherein the lower part of supporter casting die 3 is equipped with extending portion 32 and is mounted on connection when supporter 1 horizontally rotates Supporter casting die 3 on piece 111 equally rotates with it, i.e., in the present embodiment, there is no levels for supporter casting die 3 and supporter 1 The relative rotation in direction.

As shown in figure 5, the extending portion 32 of 3 lower part of supporter casting die is used to connect with supporter shaft 72, specifically, protruding into In upper fixing groove 722, for the ease of transmission, the cross section of upper fixing groove 722 and extending portion 32 is all the design of waist type, rotation process Non-slip, under the rotation of extending portion 32, entire supporter shaft 72 is also rotated with it.

Lower rotary shaft 723 below supporter shaft 72 is across pivoted arm interconnecting piece 21, pivoted arm interconnecting piece 21 and support It is to relatively rotate between body shaft 72.So that: supporter 1, supporter casting die 3, supporter shaft 72 these three components As a whole, whole to realize rotation, each other without relative rotation.And linking arm 2 is used as another entirety, with above-mentioned three A component relatively rotates so that supporter 1 with respect to linking arm 2 with supporter shaft 72 be axis carry out horizontal direction or The rotation in person's level of approximation direction.

On rotating effect, the technical program has done the design of elastic buffer and position reset.Specifically, such as Fig. 4 and Fig. 5 Shown, outer ring is arranged with reduction torsion spring 71 in supporter shaft 72.In supporter shaft 72, it is equipped with torsional spring connecting fin one 721, and in the inner ring of pivoted arm interconnecting piece 21, it is equipped with torsional spring connecting fin 2 22, the two connecting fins are respectively at reduction torsion spring 71 Both ends contradict connection.When supporter 1 rotates, torsional spring connecting fin 1 can be rotated relative to torsional spring connecting fin 2 22, to press Contracting reduction torsion spring 71, reduction torsion spring 71 generate elastic force, after user's body leaves supporter 1, this elastic force to torsional spring connecting fin Can rebound supporter 1 initial preset position.

The technical program also adds the function of limit and elastic force preload on the basis of elastic force.Specifically, such as Fig. 5 and Shown in Fig. 6, in the lower half portion of supporter shaft 72, it is equipped with lower rotary shaft 723, lower rotary shaft 723 is externally connected with limiting device 8.Limit Position device 8 includes spill spin block 81, is connect with the lower half portion of lower rotary shaft 723, and outer wall is equipped with the convex block 811 of evagination.And The lower half portion of pivoted arm interconnecting piece 21 is additionally provided with two limit barrier sheets 24, exists between the two limit barrier sheets 24 for convex The rotation of block 811 provides the rotational area 23 in space.Spill spin block 81 is equally fixedly connected with supporter shaft 72, and opposite turn does not occur It is dynamic, the then rotational angle of the rotational angle of supporter 1 i.e. convex block 811 in rotational area 23.

In addition to the effect of limit, the design of limiting device 8 equally plays the role of torsional spring preload, the position of preset rotational area 23 It is set to the position that reduction torsion spring 71 has generated suitable elastic force, 1 linking arm 2 of supporter is made to have the function for relatively rotating and resetting Energy.

It has been explained hereinbefore that supporter 1, be either still used as backboard as waist support, opposite linking arm 2 in the horizontal direction or Another utility model of this case is introduced below with the structural principle that supporter shaft 72 is that axis is rotated in person's level of approximation direction Point, i.e. supporter 1 can do pico- movement in another direction, such as vertical direction, so that the patch of supporter 1 and human body It is right more preferable, improve the comfort level that people leans on down.

As shown in Fig. 3, Fig. 4 and Fig. 7, sliding groove 13 is equipped in upper connection sheet 112, sliding groove 13 is close to supporter 1 Position, which is equipped with, puts piece 12.And supporting element casting die 3 mentioned above is just mounted in connection sheet 111.Specifically, extending portion 32 It extend into sliding groove 13, and can be moved in sliding groove 13.Also, as shown in figure 4, supporting element casting die 3 is apart from support There is one section of mobile gap 6 between body 1, this section of gap setting to have between supporter 1 and supporting element casting die 3 and slide relatively It is dynamic.

As shown in figure 4, in the present case, rotating connector 5 is specially standing screw, as a main connector, Across two connection sheets 11, across supporting element casting die 3, supporter shaft 72, spill spin block 81 and the spiral shell in lower connection sheet 112 Bolt through hole 15, lower end is fixed using nut.Such setting, so that supporter 1 is fixed in vertical direction lower end, upper end Since the presence in mobile gap 6 can be slided, entire supporter 1 can rotate in vertical direction.

As shown in figure 4, in order to further increase the fit and comfort of 1 vertical direction of supporter rotation, in supporting element Between casting die 3 and supporter 1, that is, moves and be equipped with resetting block 4 between gap 6.Resetting block 4 can be by elastic material such as rubber Glue or spring are made.As shown in fig. 7, side guide piece 31 is equipped on supporting element casting die 3, and the bending design of resetting block 4, main conflict Portion 41 and supporter 1 contradict, and the bending design of the briquetting interconnecting piece 42 at both ends, or vertical with main abutting portion 41, are caught in side and lead Into piece 31, good stability.
