New description: [New technical field] [0001] This creation relates to a sofa, especially a headrest structure for a sofa that can withstand large loads. [Prior Art] [0002] Sofa has become an indispensable must-have furniture in the home. The general consumer _ in the selection of the sofa is not only beautiful, gorgeous and noble, but the most important thing is the comfort of the sofa. Spatial visual experience. Most of the traditional sofas have a fixed design of the headrest structure, which is an adjustable design of the headrest structure, as disclosed by the creator's previously proposed new national patent certificate number M348538; Although the pillow structure can withstand a large load, but the height is fixed, 'can not be adjusted according to the user of different heights. In addition, the aforementioned patents can effectively overcome the aforementioned problems, because the load that can be withstood by the human body is affected by the direction of the human body's head force, and cannot withstand large forces, and is liable to cause damage and the like. Problem 〇 [New Content] [0003] One of the purposes of the present invention is to provide a headrest structure for a sofa that can withstand large loads, which utilizes the tilting arrangement of the insertion rod and can be applied to the human head. The direction of the force is in an orthogonal relationship', and the load on the load of the headrest portion can be increased. [0004] In order to achieve the above object, the present invention provides a headrest structure for a sofa that can carry a large load, the sofa has a back pad. The head is tied to form form number A0101. Page 3 of 15 The utility model comprises at least one socket, a plug rod, a headrest and a linkage mechanism, the socket comprises a tube body, the tube body has a socket, the tube body is fixed on the back pad, and the insertion body is The center line of the hole is disposed in a non-parallel relationship with the vertical line; the insertion rod is inserted parallel to the center line of the insertion hole; the headrest portion is formed above the back pad; one end of the linkage mechanism is connected to the insertion rod The other end is connected to the headrest portion. [0005] In order to achieve the above object, the present invention provides a headrest structure for a sofa that can withstand a large load, the sofa having a back pad, the headrest structure including at least one receiving seat, a plug rod and a headrest The socket includes a tube body having a socket fixed to the back pad such that the center line of the jack is disposed in a non-parallel relationship with the vertical line; the plug rod Parallel to the center line of the jack; the headrest portion is coupled to the jack and formed over the back pad. [0006] The present invention also has the following effects, since the insertion rod can be inserted and removed with respect to the insertion hole of the tube body, and the height adjustment can be made. The other body and the connecting rod are tapered, with automatic centering and stable positioning. [Embodiment] [0007] The detailed description and technical contents of the present invention are described below with reference to the drawings, but the drawings are only for reference and description, and are not intended to limit the creation. [0008] Please refer to the first and second figures, the present invention provides a headrest structure for a sofa that can withstand a large load, which mainly includes a receiving base 10, a plug rod 20, a headrest portion 30 and a Linking mechanism 40. Form No. A0101 Page 4 of 15 [0009] The socket 10 can be provided in a single or plural manner, and includes a circular seat plate 11 and a tubular body 12, and three through holes 111 are formed in the seat plate 11 The body 12 is a conical tube and has a receiving hole 121. One end of the tubular body 12 is connected to the end surface of the corresponding seat plate 11, and an inner angle is arranged between the axial line of the insertion hole 121 and the seat plate 11. The angle of the inner angle is less than 90 degrees. [0010] The insertion rod 20 is a hollow conical tube body, which is inserted corresponding to the aforementioned insertion hole 121, and the axis line of the insertion rod 20 is parallel to the center line of the insertion hole 121, thereby utilizing the plugging. The tapered body of the rod 20 is automatically centered and has a stable fixing effect when assembled with the jack 121. [0011] The headrest portion 30 is a rectangular body made of a combination of foam, cloth or leather, but is not limited by such a shape, and may also be shaped by other various geometric shapes in the headrest portion 30. The inside has a fixing plate 31 ^ [0012] The linking mechanism 40 includes a ratchet 41 fixed to the end of the insertion rod 20, a rotating base 42 fixed to the headrest portion 30, and a moving arm 43 framed on the rotating base 42. The rotating base 42 is pivotally connected to the ratchet 41 through a pivot 44, so that the rotating base 42 can be angularly adjusted relative to the insertion rod 20. The free end of the swinging arm 43 is associated with the ratchet 41 to limit the ratchet 41. Can only be rotated in one direction. Further, the rotary base 42 is slidably fastened to a fixing plate 31 of the headrest portion 30 by a screwing member such as a screw. [0013] Please refer to the second to fifth figures. 'The headrest structure of the present invention can be applied to a sofa 5'. The sofa 5 has a back pad 51, wherein the tube 12 of the receiving seat 1 is pierced. The back pad 51 is disposed such that the center line of the insertion hole 121 is in a non-parallel relationship with the # perpendicular line (i.e., perpendicular to the horizontal line). The insertion rod 20, the headrest portion 30 and the linkage mechanism 4〇 are assembled into a single member, and the form number A0101 is 5/15 M393235. The insertion rod 20 is connected to the aforementioned insertion hole 121. The headrest portion 30 is formed on the back pad 51. In use, the direction of the force of the head of the human body is substantially orthogonal to the axial extension of the insertion rod 20, so that the headrest structure can withstand a large load. Further, the addition of the interlocking mechanism 40 can be utilized to adjust the headrest portion 30 to various angles with respect to the back pad 51. [0014] Please refer to the sixth figure, the headrest structure of the present invention may be in the form of the present embodiment, except for the above-mentioned embodiment, which mainly includes a socket 10, a plug rod 20 and a headrest portion. 30. The socket 10 is fixed to the back pad 51, and the insertion rod 20 is inserted into the oblique insertion hole 121, and the axis line of the insertion rod 20 is parallel to the center line of the insertion hole 121, and the headrest portion 30 (not shown) is connected to the insertion rod 20 and formed above the backing 51; thus, it also has the equivalent effect of the foregoing embodiment. [0015] In summary, the headrest structure of the present invention for the sofa can withstand a large load can achieve the intended purpose of use, and solve the lack of conventional knowledge, and is completely new and novel because of its novelty and progress. The patent application requirements are filed in accordance with the Patent Law. Please check and grant the patent in this case to protect the rights of the creator.
