Detailed Description

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

with reference to the accompanying drawings: the backrest provided with the backrest decorative cover convenient to mount comprises a backrest body 1, wherein the backrest body 1 is provided with a cross rod 2, the cross rod 2 and a part below the cross rod 2 are covering areas 3 of the backrest body 1, the covering areas 3 are covered with a decorative cover 4, the backrest body 1 is provided with two first long-axis mounting surfaces 11 and two first short-axis mounting surfaces 12 at the covering areas 3, at least one clamped piece 5 is mounted on each first long-axis mounting surface 11 and each first short-axis mounting surface 12, the first long-axis mounting surface 11 is positioned on the cross rod 2, the decorative cover 4 is provided with two second long-axis mounting surfaces 41 and two second short-axis mounting surfaces 42 facing the backrest body 1, the number of clamped pieces 6 which is the same as that of the clamped pieces 5 is mounted on each second long-axis mounting surface 41 and each second short-axis mounting surface 42, the first long-axis mounting surface 11 positioned above is provided with a plurality of clamped pieces 7, wherein each of the to-be-jacked pieces 7 is positioned between adjacent to-be-jacked pieces 7 of all the to-be-jacked pieces 7 of the first long-axis mounting surface 11, the second long-axis mounting surface 41 positioned above is provided with the same number of jacking pieces 8 as the to-be-jacked pieces 7, and each jacking piece 8 is positioned between adjacent jacking pieces 8 of all the jacking pieces 8 of the second long-axis mounting surface 41. The double restraint is realized by the clamping piece 5 and the clamping piece 6, and the top piece 7 and the top piece 8, so that the traditional bolt fixing trouble is replaced.

The card 5 has a channel 51, the channel 51 is provided with a left end opening 51-a and a right end opening 51-b on the backrest body 1, wherein the card 6 is arranged in the right end opening 51-b to move along the channel 51, an upper stop 51-b1 is fixed at the right end opening 51-b, and the card 6 is connected with the card 5 when acting on the upper stop 51-b 1. The clamped piece 5 is of an embedded structure, the clamped piece 6 is guided to enter the channel 51 through the right end opening 51-b, the upper stop block 51-b1 enables the channel 51 to be internally provided with a limiting structure, the clamped piece 6 is limited in the channel 51, and the clamped piece 5 is in card connection fit, so that the decorative cover 4 is stably installed on the backrest body 1.

A lower stop block 51-a1 is fixed at the left end opening 51-a, the lower stop block 51-a1 and the upper stop block 51-b1 are staggered left and right, and the clamping piece 6 abuts against the lower stop block 51-a1 in preassembly and assists the top piece 8 to be placed above the top piece 7. This structure not only needs fastener 6 to realize the card with by fastener 5 and is connected, and top 8 and by the fixed piece 7 need also realize the top and connect, and when fastener 6 blocks in by fastener 5, need top 8 to be located by the fixed piece 7 top promptly, so set up lower dog 51-a1, lower dog 51-a1 has the height, when making fastener 6 support in lower dog 51-a1 top, can increase the use height of top 8, this height is located by top 7 tops, can be simultaneously to control the top 8 and by the spacing difference between top 7, avoid the interval too big, and lead to fastener 6 unable smooth entering by the fastener, thereby realize once action, accomplish the cooperation of two kinds of connected modes.

The channel 51 further has protruding strips 9 located on both sides of the channel 51 and symmetrically arranged on the backrest body 1, and the distance between the two protruding strips 9 is for the clip 6 to pass through. Two sand grips 9 play the guide effect, and the interval between two sand grips 9 is unanimous with passageway 51's width, so when fastener 6 gets into, stably exist between two sand grips 9, the condition of skew can not appear, also plays the positioning action simultaneously for dress trim cover 4 can close regional 3 quick accurate counterpoints with the lid, and guarantee that every fastener 6 can both be gone into smoothly in being blocked by fastener 5, and efficient.

The clip member 6 includes a mounting plate 61 and a latch 62, and the mounting plate 62 is obliquely fixed to the second long-axis mounting surface 41. The mounting plate 61 plays a role in connection, one side is connected with the decorative cover 4, the other side is connected with the clamping tongue 62, the clamping tongue 62 connected to the mounting plate 61 is enabled to extend to the left end of the upper stop block 51-b1 to be attached to the left end face of the upper stop block when the clamping tongue 62 is clamped into the clamped piece 5 according to the length of the mounting plate 61, the mounting plate 61 abuts against the lower end of the upper stop block 51-b1, the upper stop block 51-b1 is completely clamped in the clamping piece 6, the clamping tongue 62 can smoothly enter the clamped piece 5 through oblique arrangement, an adjusting space is formed after the clamping tongue 62 enters the clamping piece, the adjusting space can be adjusted, the ejector 8 of the other constraint structure abuts against the jacked piece 7, and double constraint is achieved.

The contact part of the top piece 7 and the top piece 8 is a plate body with a plane section. The structure of ejecting 8 and being ejected 7 has been optimized with face-to-face contact to the face, and simple process easily the shaping does not have other complicated cooperation structures, and both when the cooperation, by the contact surface of ejecting 7 with ejecting 8 the contact surface laminating can, convenient and fast.

The lower surface of the jacked piece 7 and the upper surface of the jacking piece 8 are both provided with a plurality of reinforcing ribs 10. The reinforcing ribs 10 increase the use strength of the top parts 7 and 8, and the problem of poor stress resistance of a single plate is solved, so that the decorative cover 4 can be stably arranged on the backrest body 1.

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.
