Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

with reference to the accompanying drawings: this kind of waist is leaned on convenient to equipment, lean on body 1 including the waist, body 1 is leaned on the waist including the waist and leans on inner shell 11, the waist leans on outer cover 12, the waist leans on inner shell 11 to be equipped with a plurality ofly by fastener 2, it is preceding two to have by fastener 2, relative back that sets up by cap 21, the waist leans on outer cover 12 to be equipped with the fastener 3 that is equal by the number of the card quantity, fastener 3 has two preceding, the relative card 31 that sets up in back, there is spacing distance and formation bayonet socket 32 between two cards 31, two cards 31 act on two when being blocked cap 21 realize that the waist leans on outer cover 12 lid to fit the waist by inner shell 11 through bayonet socket 32.

The clamped piece 2 is also provided with two left and right bottom blocks 22, the bottom block 22 is provided with a front end bulge 22-a and a rear end bulge 22-b, wherein two ends of a clamped cap 21 positioned at the front end are respectively connected with the front end bulge 22-a at the left end and the front end bulge 22-a at the right end, and two ends of the clamped cap 21 positioned at the rear end are respectively connected with the rear end bulge 22-b at the left end and the rear end bulge 22-b at the right end. The arrangement can reinforce the bottom of the clamped cap 21, namely, the strength of the clamped cap for resisting stress is increased, and the damage caused by overlarge stress when the clamping piece 3 is clamped is avoided.

The clamped cap 21 comprises a connecting plate 21-a and a stop 21-b fixed on the upper surface of the connecting plate 21-a, wherein the stop 21-b extends outwards, and the lower surface of the stop and the outer surface of the connecting plate 21-a form a clamping area 21-c. The principle is that the stop block 21-b extends outwards, namely the width is larger than that of the connecting plate 21-a, the convenience of clamping installation and disassembly is considered, the outward extending distance of the stop block 21-b is the width of the connecting plate 21-a, and is just the part extending outwards, the lower surface of the stop block 21-b is in an L shape with the outer surface of the connecting plate 21-a, so that after the clamping piece 3 is clamped, namely the clamping piece 31 is positioned below the stop block 21-b and can be attached to the lower surface extending from the stop block 21-b and the outer surface of the connecting plate 21-a, stable clamping is realized, meanwhile, the connecting plate 21-a has two states of an unstressed state and a stressed state, namely the connecting plate 21-a is not changed, the stressed state is that when a user clamps the clamping piece 3, the downward pressure needs to be applied, and when the connecting plate 21-a is influenced by the downward pressure, an inward extrusion force is automatically generated, so that the part, contacting with the card 32, of the connecting plate 21-a is inclined inwards, the inclination angle is 5-10 degrees, the clamping piece 3 can enter conveniently, after the force is released, the connecting plate 21-a returns to the original position, stable clamping is realized, and meanwhile, when the clamping piece is disassembled, the clamping piece is also inclined inwards due to the stress, and the disassembly is also convenient.

The upper surface of the stopper 21-b is a slope inclined outward. The ramp has a guiding function to facilitate the snapping in of the card 31.

The lumbar cover 12 includes a lumbar portion 12-a and a plate body 12-b, the plate body 12-b being embedded in the lumbar portion 12-a, wherein the plate body 12-b has a channel 12-b1, the channel 12-b1 extending through the plate body 12-b, wherein two cards 31 reside within the channel 12-b 1. In consideration of the comfort of the waist support, the outer cover 12 of the waist support is composed of two parts, the waist support part 12-a is made of soft materials, and in consideration of the stability of clamping, the plate body 12-b made of hard materials is added, so that the clamping piece 3 has rigidity, and the stability of clamping is ensured while the comfort is achieved.

The channel 12-b1 is a limited installation space, the length of the channel is consistent with the length of the clamped cap 21, the width is larger than the width of the clamped cap 21, the clamped card can avoid the clamped card 2 from moving in the channel 12-b1, and the installation space of two cards 31 is also provided, only one connection surface is arranged between a single card 31 and the channel 12-b1, the arrangement is such that when the card 31 is clamped, the card 31 is stressed, because of the block 21-b, and because of the installation mode of the card 31, the stressed end of the card 31 is prevented from interference, gradually bends upwards, bends to the bending outer surface to abut against the outer surface of the block 21-b, so as to avoid the block, and gradually separates from the block 21-b along with the increase of the installation depth, when the installation depth reaches to the block 21-b, the card 31 resets and is completely clamped on the clamped cap, namely, the upper surface of the card 31 is abutted against the lower surface extended from the block 21-b, The front end face of the card 31 is attached to the outer surface of the connecting plate 21-a, so that the card is limited on the clamped piece 2 to complete stable clamping.

The plate body 12-b also has a plurality of heat sinks 12-b 2. The heat dissipation opening 12-b2 can increase the heat dissipation effect of the lumbar outer cover 12 and also increase the stability of the embedded plate body 12-b.

The lumbar portion 12-a is a cotton pad. The cotton material is not only soft, can have obvious comfort when the user leans on, and the gas permeability of cotton material is good moreover, especially in hot summer, avoids sitting for a long time and generates heat, sends out the scald.

Example 2:

While the invention has been shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the appended claims.
