[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 5 As shown, the utility model provides a car seat back with a detachable lumbar support, comprising a seat back 1, the inner cavity of the seat back 1 is movably sleeved with a guide rod 2, the right side of the guide rod 2 is fixedly connected with a mounting block 3, the surface of the mounting block 3 is movably sleeved with a mounting sleeve 4, the front side of the mounting sleeve 4 is fixedly connected with a plug-in tube 5, the inner cavity of the plug-in tube 5 is fixedly connected with a plug-in spring 6, the side of the plug-in spring 6 close to the mounting block 3 is fixedly connected with a plug-in block 7, the side of the plug-in block 7 away from the mounting block 3 is fixedly connected with a pull ring 8, and the right side of the mounting sleeve 4 is fixedly connected with a lumbar support 10;

[0022] The plug-in spring 6 is contracted by pulling the pull ring 8, and then the mounting sleeve 4 is sleeved on the outer surface of the mounting block 3. The pull ring 8 is loosened, so that the tension of the plug-in spring 6 drives the plug-in block 7 to be inserted into the inner cavity of the mounting block 3, thereby plugging and fixing the mounting block 3 and the mounting sleeve 4. Then the user can use the lumbar support 10 to support the waist. When disassembly is required, the lumbar support 10 can be disassembled by pulling the pull ring 8, thereby realizing the disassembly and installation of the lumbar support 10 from the front side, and the fixing force of the lumbar support 10 is increased to ensure that the lumbar support 10 will not shift during use.

[0023] The side of the mounting block 3 away from the mounting sleeve 4 is fixedly connected with a threaded rod 11, the surface of the threaded rod 11 is meshed with a threaded tube 12, and the side of the threaded tube 12 away from the mounting block 3 is fixedly connected with a twisting rod 14;

[0024] By holding the twisting rod 14 and rotating the threaded tube 12, the threaded rod 11 meshed with the threaded tube 12 is driven to move along the axial direction of the threaded tube 12, thereby driving the lumbar support 10 to move along the axial direction of the threaded rod 11 and the guide rod 2, so as to adjust the depth of the lumbar support 10, thereby achieving the depth of the lumbar support 10 being adjustable according to the needs of the user, and supporting the user's waist at different depths.

[0025] The pull ring 8 is composed of a round rod and a round ring. The round rod is located at the center of the inner cavity of the plug spring 6. The round rod is fixedly connected to the plug block 7. The round ring is located on the outside of the plug tube 5.

[0026] The round rod is fixedly connected to the plug-in block 7, so when the user pulls the ring, the plug-in block 7 can be driven to move, thereby allowing the plug-in block 7 to enter and exit the inner cavity of the installation block 3, and then the ring is located on the outside of the plug-in tube 5, allowing the user to pull the plug-in block 7 to move, thereby controlling the installation of the installation sleeve 4.

[0027] Among them, a mounting hole 9 is opened on one side of the mounting block 3 close to the plug-in block 7, and the plug-in block 7 fits in the inner cavity of the mounting hole 9;

[0028] Through the mounting socket 9 on the side of the mounting block 3 close to the plug-in block 7, the plug-in block 7 can be plugged into the inner cavity of the mounting socket 9 to fix the mounting block 3. Then, the plug-in block 7 is fitted into the inner cavity of the mounting socket 9 to prevent the mounting sleeve 4 from shaking when the plug-in block 7 is located in the inner cavity of the mounting socket 9.

[0029] A rectangular groove is provided on one side of the seat back 1 close to the lumbar support 10, and the mounting block 3 is located on the right side of the rectangular groove;

[0030] Since the mounting block 3 is located on the right side of the rectangular groove, when the lumbar support 10 is not in use, the mounting block 3 can be stored in the inner cavity of the rectangular groove by continuing to rotate the threaded tube 12, thereby avoiding excessive protrusion of the mounting block 3, which would cause the user to be pressed by the mounting block 3 when the lumbar support 10 is not needed.

[0031] The outer surface of the threaded tube 12 is fixedly connected with a mounting ring 13, and the threaded tube 12 is movably sleeved in the inner cavity of the seat back 1 through the mounting ring 13;

[0032] Through the mounting ring 13 on the outer surface of the threaded tube 12 , the threaded tube 12 can stably rotate in the inner cavity of the seat back 1 , so that the threaded tube 12 will not move during rotation, and the threaded rod 11 will move, thereby adjusting the depth of the lumbar support 10 .

[0033] The twisting rod 14 is semicircular, and the inner cavity of the threaded tube 12 is provided with a thread groove, and the threaded rod 11 is threadedly connected to the inner cavity of the threaded tube 12 through the thread groove;

[0034] Since the twisting rod 14 is semicircular, passengers in the rear row can hang items on the inner cavity of the twisting rod 14, thereby improving the convenience of users when using it.

[0035] The working principle and use process of the utility model are as follows: the user pulls the pull ring 8 to shrink the inner cavity of the plug-in tube 5 by the plug-in block 7, and then puts the installation sleeve 4 on the outer surface of the installation block 3, so that the plug-in block 7 is aligned with the installation socket 9, and then releases the pull ring 8, and inserts the plug-in block 7 into the inner cavity of the installation socket 9 through the tension of the plug spring 6, so as to fix the installation sleeve 4, and then fix the waist support 10, and then the user uses the waist support 10 to support the waist;

[0036] Then, during use, the screw rod 14 can be rotated to drive the threaded tube 12 to rotate, and the threaded tube 12 can rotate to drive the threaded rod 11 meshed with the threaded tube 12 to move along the axis of the threaded tube 12 and the guide rod 2, thereby driving the lumbar support 10 to move, and then adjusting the depth of the lumbar support 10;

[0037] And the passengers in the back row can hook and support the items by using the twisting rod 14.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
