Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the utility model will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
The specific embodiment of the utility model is as follows:
example (b): as shown in fig. 1-4, the present invention provides a chair, which comprises a chair back and a chair seat 1, wherein the chair seat 1 comprises a seat plate and a flexible cushion on the seat plate, a chassis 2 is arranged below the seat plate, and the chassis 2 comprises a connecting seat 3 and a supporting member 4. Connecting seat 3 sets up in the bottom face of seat support 1 in this scheme, is provided with linking bridge 5 on the back of the chair, linking bridge 5 and connecting seat 3 sliding connection, linking bridge 5 can slide in order to drive the back of the chair and remove on the seat depth direction of seat support 1 for connecting seat 3. The supporting member 4 is installed at the bottom end of the connecting seat 3 and connected with the bottom bracket 6 below to support the seat 1.
As a specific implementation mode, the connecting seat 3 and the seat 1 in the scheme are provided with a head end and a tail end along the seat depth direction of the seat 1, and the tail end of the connecting seat 3 and the back of the chair are adjacent to the tail end of the seat 1. As shown in fig. 4, the connecting base 3 is provided with a fixed connecting portion 14 and a sliding connecting portion 15 along the direction from the head end to the tail end thereof, and the supporting member 4 is mounted on the fixed connecting portion 14. Preferably, the connecting base 3 is provided with a positioning slot 7 on the fixed connecting portion 14, and the supporting member 4 is disposed in the positioning slot 7 and connected with the connecting base 3 through a screw. Through being provided with constant head tank 7, the location installation of the supporting piece 4 of being convenient for, and supporting piece 4 sets up in constant head tank 7, also plays the effect of hiding the shielding to supporting piece 4, and is not only more pleasing to the eye, also plays the guard action to supporting piece 4, avoids taking place to collide with.
The sliding connection portion 15 of the connecting seat 3 is provided with a sliding groove 8, and the sliding groove 8 extends along the direction from the head end to the tail end of the connecting seat 3 and penetrates through the tail end face of the connecting seat 3 to form an opening 9. Meanwhile, the groove walls on the two sides of the sliding groove 8 are provided with limiting protrusions 13 extending towards the center of the sliding groove 8 at the groove openings, and a gap 10 is formed between the two limiting protrusions 13. One end of the connecting bracket 5 is connected to the seat back, and the other end of the connecting bracket 5 is inserted into the slide groove 8 through the opening 9 and is slidable relative to the slide groove 8. And when the connecting bracket 5 is inserted into the sliding groove 8, the limiting bulges 13 at the two sides of the notch of the sliding groove 8 are propped against the bottom end of the connecting bracket 5 to form a bottom support, and the limiting bulges 13 play a role in supporting and fixing the connecting bracket 5.
The scheme also comprises a locking component, when the connecting bracket 5 slides to a designated position relative to the connecting seat 3, the locking component acts on the connecting bracket 5 to force the connecting bracket 5 and the connecting seat 3 to be relatively fixed.
Specifically, as shown in fig. 2 and 3, the locking assembly includes a knob handle 11, and the knob handle 11 is located in the gap 10 between the two side limiting protrusions 13. The bottom of knob handle 11 is provided with the threaded rod, and the tail end of linking bridge 5 is provided with logical groove 12, and the extending direction that leads to groove 12 is the same with the extending direction of sliding tray 8. The threaded rod at the bottom end of the knob handle 11 passes through the through groove 12 to be in threaded connection with the connecting seat 3. When the connecting bracket 5 slides to a designated position relative to the connecting seat 3, the knob handle 11 can be rotated to cooperate with the connecting seat 3 to clamp the connecting bracket 5, so that the connecting bracket 5 and the connecting seat 3 are forced to be relatively fixed. Because the gap 10 is reserved between the limiting bulges 13 on the two side groove walls of the sliding groove 8, and the knob handle 11 is positioned in the gap 10, the threaded hole on the connecting seat 3 can be quickly found, and then the threaded rod passes through the through groove 12 to be in threaded connection with the connecting seat 3, so that the device is convenient and quick. And a gap 10 is reserved between the limiting bulges 13 and does not completely wrap the bottom end surface of the connecting bracket 5, so that the contact area between the connecting bracket 5 and the sliding groove 8 is reduced, and the friction force is reduced, so that the sliding is facilitated.
Preferably, the sliding slot 8 extends upward along the direction from the head end to the tail end of the connecting seat 3. When connecting bracket 5 slides by the head end to the tail end direction of connecting seat 3 in sliding tray 8, because sliding tray 8 slope upwards extends, keeps away from the front end of seat support 1 gradually at the back of the chair for the in-process of seat depth crescent, connecting bracket 5 also drives the back of the chair slope and rises, accomplishes the regulation of back of the chair height.
Different from the supporting piece 4, the connecting seat 3 is made of plastic materials in the scheme, and the connecting seat 3 is mainly used for being in sliding fit with the connecting support 5 and does not need high material strength, so that the connecting seat is made of the plastic materials, and the material cost is reduced.
The present invention and its embodiments have been described above schematically, without limitation, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching, without departing from the spirit of the utility model, the person skilled in the art shall not inventively design the similar structural modes and embodiments to the technical solution, but shall fall within the scope of the utility model.
