Background technique

Chairs are widely used in families or offices. In order to ensure the comfort of chairs, existing office chairs usually have functions such as adjustable backrests and adjustable armrests. This can satisfy people with different body shapes and different sitting postures. use needs. However, the adjustable backrest can only adapt to the posture of the waist, and the adjustable armrest can only adapt to the bearing of the arms. Both of the above-mentioned two cannot meet the needs of the adjustment of the hips and the front and rear positions of the human body. Therefore, the chair only has an adjustable backrest and adjustable armrests. Adjustment is obviously not enough. In order to achieve higher standards of comfort and convenience of use, and to meet the needs of users with more levels and orientations, it is also necessary to make the seat of the chair adjustable. However, the existing chairs generally do not have chairs. The adjustable function of the seat is due to the lack of an adjustable, simple and convenient adjustment mechanism.

Therefore, there is a need for an adjustment mechanism that can adjust the position, is simple to operate, and is convenient to use.

Detailed ways

In order to describe the technical content, structural features, and achieved effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

As shown in Fig. 1 and Fig. 2, the sliding bottom plate 100 of the utility model is used as a seat of a chair, and it includes a bottom plate 1, a base 2, a buckle 3, a handle 4, a rotating shaft 5, a first reset spring 6, a second reset spring A spring 7 and a sliding limiter 8; the base plate 1 slides relative to the base 2, the base plate 1 is fixedly provided with a mounting seat 9, and the buckle 3 is pivotally connected to the mounting plate through the rotating shaft 5 Seat 9. The buckle 3 is fixedly connected to one end of the rotating shaft 5 , and the other end of the rotating shaft 5 is fixedly connected to the handle 4 so as to drive the buckle 3 to move through the handle 4 . The buckle 3 can be conveniently operated by being arranged on the handle 4, which improves the convenience of operation. The base 2 is provided with a plurality of engaging teeth 21 corresponding to the locking member 3 along the sliding direction of the bottom plate 1, and the locking member 3 is selectively engaged with at least one of the engaging teeth. The part 21 is used to lock the relative position of the bottom plate 1 and the base 2 after sliding.

As shown in Figure 1 and Figure 2 again, the first return spring 6 provides an elastic force to engage the buckle 3 with the engaging teeth 21, and the first return spring 6 is a torsion spring , the torsion spring is placed in the handle 4 , and one end is in contact with the mounting base 9 , and the other end is in contact with the handle 4 . The first return spring 6 can make the buckle 3 engage with the engaging teeth 21 automatically, even if the bottom plate 1 and the base 2 are automatically locked to prevent accidental sliding. The second return spring 7 is connected between the base plate 1 and the base 2 and arranged along the sliding direction of the base plate 1, the second return spring 7 is a tension spring, one end is connected to the base plate 1, The other end is connected to the base 2; the second return spring 7 provides an elastic force to make the bottom plate 1 and the base 2 slide close to each other. The second return spring 7 can make the bottom plate 1 and the base 2 automatically return to the initial state, thereby also indirectly realizing the automatic adjustment of the retracted position between the bottom plate 1 and the base 2, improving the convenience of use .

As shown in Figure 1 again, the bottom plate 1 is provided with an elongated hole 11 along the sliding direction, the bottom surface of the bottom plate 1 is provided with a concave sliding groove 12, and the elongated hole 11 is opened in the sliding groove 12 The bottom of the bottom, the sliding limit piece 8 is slidably arranged in the sliding groove 12, the upper end of a shaft pin 22 is fixed with the base 2, and the lower end of the shaft pin 22 is inserted into the elongated hole 11 And it is fixedly connected with the sliding limiting piece 8. There is also a sound insulation sheet 10 between the bottom plate 1 and the base 2, and the sound insulation sheet 10 can prevent the bottom plate 1 and the base 2 from producing harsh friction sounds when sliding.

Based on the above and in conjunction with Figures 2 to 4, the working principle of the sliding bottom plate 100 of the present invention is described in detail below, as follows:

At the beginning, the bottom plate 1 and the base 2 are overlapped. At this time, under the elastic force of the first return spring 6, the buckle 3 is engaged with the first engaging On the tooth portion 21 , at this time, the relative position between the bottom plate 1 and the base 2 is fixed. When the bottom plate 1 needs to be elongated, the handle 4 is rotated, and the handle 4 drives the buckle 3 to rotate through the rotating shaft 5, so that the buckle 3 is separated from the engaging teeth 21, and at the same time The first return spring 6 is compressed. At this time, the base plate 1 and the base 2 are unlocked, and the base plate 1 is pulled by the handle 4, so that the base plate 1 slides relative to the base 2 and pulls Stretch the second return spring 7, the base plate 1 can slide out to the base 2, at this time, adjust the sliding distance of the base plate 1, and then release the handle 4, the buckle 3 Under the action of the elastic restoring force of the first return spring 6, it will be rotated and engaged with the corresponding engaging teeth 21. At this time, the bottom plate 1 and the base 2 will be locked on the at the current position. When the bottom plate 1 needs to be shortened, it is only necessary to unlock the bottom plate 1 and the base 2 according to the above operation, and pull the bottom plate 1 under the elastic restoring force of the second return spring 7 to make the bottom plate 1 shrinks relative to the base 2, and then lock the relative positions of the bottom plate 1 and the base 2 again. Compared with the prior art, because the utility model makes the bottom plate 1 and the base 2 slide, and the base 2 is provided with engaging teeth 21, and the bottom plate 1 is set The buckle 3 makes the buckle 3 movable. Therefore, when the buckle 3 is engaged with the engaging teeth 21, the bottom plate 1 and the base 2 can be opposite to each other. Position locking, and when the buckle 3 leaves the engaging teeth 21, the bottom plate 1 and the base 2 can slide against each other. The adjustment of the position between them only needs to operate the buckle 3, which is easy to operate and very convenient to use.

What is disclosed above is only a preferred example of the utility model, and of course the scope of rights of the utility model cannot be limited with this. Therefore, equivalent changes made according to the patent scope of the utility model still belong to the scope covered by the utility model .
