The structure includes a housing, and an inner box is slidably connected inside the housing. An elevating mechanism is arranged inside the inner box, and the elevating mechanism includes three outer cylinders, and inner cylinders are slidably connected to the inner walls of the three outer cylinders.

[0006] For the sofa with adjustable height in this utility model patent, its general structural principle is as follows: grasping the crank and rotating the rotating rod drives the three gears to rotate synchronously and engage with the toothed block, and the toothed block drives the inner cylinder to slide upward along the inner wall of the outer cylinder, so that the three inner cylinders push the inner box upward, and the inner box slides upward along the inner wall of the housing. Similarly, rotating the crank in the reverse direction drives the rotating rod to rotate and move in the reverse direction, thereby enabling the elevation adjustment of the sofa.

[0007] However, during the actual use process of this guiding and deviation-correcting device, there are at least the following deficiencies, that is to say, they are the technical problems to be solved by this utility model.

[0008] The crank is fixedly arranged on the outside of the sofa, which not only increases the difficulty of packing and transporting the sofa, but also is easily squeezed and damaged during transportation.

[0009] Therefore, in summary, there is an urgent need for a new type of sofa operating handle that is convenient to disassemble. Content of the Utility Model

[0010] The utility model provides a sofa operating handle that is easy to disassemble. By setting a fixed rod unit, a driving outer tube unit, and an installation handle unit, the following can be achieved: The fixed rod unit and the driving outer tube unit are inserted into the armrest. When the hole of the driving outer tube unit passes through the marbles on the fixed rod unit, the marbles are limited and clamped, completing the installation. The installation handle unit is located outside the armrest. By rotating the installation handle unit, the fixed rod unit can be driven to adjust the rotation angle of the sofa. When disassembling, only need to press the marbles to remove the driving outer tube unit and the installation handle unit, making the installation and disassembly of the sofa operating handle very convenient. And during transportation, the sofa operating handle can be disassembled for transportation, which will not damage the sofa operating handle and at the same time reduces the transportation difficulty, and the selection flexibility of the sofa operating handle is stronger.

[0033] The following is only a preferred embodiment of the present utility model, and does not limit the scope of the present utility model.

[0034] As shown in the Figure 1-8 drawings, a detachable sofa operating handle is characterized in that: the structure includes a fixed rod unit 1 arranged on the sofa running mechanism a and located inside the armrest b, a driving outer tube unit 2 sleeved on the fixed rod unit 1, and an installation handle unit 3 arranged on the driving outer tube unit 2 and located outside the armrest b.

[0035] In this embodiment, as Figure 7 shown, the existing sofa operating handle connects the fixed rod unit 1 and the driving outer tube unit 2 through bolts, making the installation and disassembly of the sofa operating handle difficult. During transportation, the operating handle is exposed outside the armrest for packing, and most of the operating handles are made of plastic, resulting in the operating handle being easily damaged by external force bumps during transportation, thus affecting the normal use effect of the operating handle. As Figure 8 shown, this figure shows the connection method of the operating handle of this application. The fixed rod unit 1 and the driving outer tube unit 2 are detachably installed through the jumping bean spring 102.

[0036] In addition, the function of the fixed rod unit 1 is to connect with the sofa running mechanism a. One end of the driving outer tube unit 2 is provided with the installation handle unit 3, and the other end is inserted into the fixed rod unit 1. The fixed rod unit 1 and the driving outer tube unit 2 are square tubes, so that rotating the installation handle unit 3 can control the sofa running mechanism a, thereby adjusting the running mode of the sofa, which can be applied to adjusting the backrest angle, adjusting the footrest angle, adjusting the massage function intensity, etc. The fixed rod unit 1 and the driving outer tube unit 2 are arranged inside the sofa, mostly arranged inside the armrest b, and the installation handle unit 3 is exposed outside the sofa. During transportation, the fixed rod unit 1 and the driving outer tube unit 2 are separated and arranged. The fixed rod unit 1 is fixedly arranged inside the armrest b, which does not affect packing and transportation, and the structure is stable and firm. The driving outer tube unit 2 and the installation handle unit 3 are additionally packed, thereby reducing the damage to the driving outer tube unit 2 and the installation handle unit 3 during transportation, and at the same time, the packing space can be further compressed. During installation, insert the driving outer tube unit 2 into the through hole reserved in the armrest b and insert it into the fixed rod unit 1. When the aperture of the driving outer tube unit 2 passes through the marbles on the fixed rod unit 1, the marbles are limited and clamped, thus completing the installation; when disassembling, just press the marbles to pull out the driving outer tube unit 2. The installation and disassembly are very convenient and fast, and during transportation, the sofa operating handle can be disassembled and transported, which will not damage the sofa operating handle, and at the same time, the transportation difficulty is reduced, and the selection flexibility of the sofa operating handle is stronger.

[0037] The fixed rod unit 1 includes a plug rod 101 arranged on the sofa running mechanism a and a jumping bean spring 102 arranged on the plug rod 101.

[0038] In this embodiment, the plug rod 101 is connected to the sofa running mechanism a of the sofa, and drives the sofa running mechanism a to operate by its own rotation. The jumping bean spring 102 is arranged on the plug rod 101 and is used for clamping with the sleeve 201 to achieve a locking effect. As Figure 7As shown, the existing plug rod 101 and the sleeve 201 are both provided with reserved holes and fixed by bolts, while in this application, as Figure 8 shown, a jumping bean spring 102 can be arranged on the reserved hole of the original plug rod 101, so as to solve the problem that the plug rod 101 and the sleeve 201 are fixedly arranged and inconvenient to install and disassemble. At the same time, the structure and settings of the original sofa can be not changed, and the flexibility is strong.

[0039] The driving outer tube unit 2 includes a sleeve 201 and a positioning hole 202 arranged on the sleeve 201 and used for clamping the jumping bean spring 102.

[0040] In this embodiment, the sleeve 201 is a square tube for sleeving the plug rod 101. The positioning hole 202 on the sleeve 201 is correspondingly arranged with the jumping bean spring 102 on the plug rod 101. When the positioning hole 202 passes through the jumping bean spring 102, the jumping bean spring 102 can be limited, so as to fix the sleeve 201 and the plug rod 101. It only needs to insert the sleeve 201 and the plug rod 101 after corresponding their positions, and the installation is convenient. When disassembling, only need to press the jumping bean spring 102 to make it retract into the positioning hole 202, then the sleeve 201 can be pulled out.

[0041] The installation handle unit 3 includes a handle 301 arranged on the sleeve 201.

[0042] In this embodiment, the handle 301 is connected to the sleeve 201 and is located on the outer side of the sofa, which is convenient for operation to control the sofa running mechanism a.

[0043] There are 2 jumping bean springs 102.

[0044] In this embodiment, there are two jumping bean springs 102, which can double-lock or adjustably lock the sleeve 201, so as to meet the installation and disassembly requirements of the sleeve 201 with different lengths.

[0045] The positioning holes 202 are arranged in 2 - 3.

[0046] In this embodiment, the positioning holes 202 are arranged in 2 - 3, which can make the installation of the sleeve 201 have more selectivity, and the flexibility and practicability are better.

[0047] The driving outer tube unit 2 further includes a screw connection hole 203 arranged on the sleeve 201. The installation handle unit 3 further includes an installation hole 302 on the side end of the handle 301 and used for aligning with the screw connection hole 203, and a fixing screw 303 arranged on the installation hole 302 and used for connecting the screw connection hole 203.

[0048] In this embodiment, the screw hole 203 is arranged at a position of the sleeve 201 close to the installation handle unit 3 for connecting with the handle 301. The installation hole 302 is arranged at the side end of the handle 301 and is fixed by the fixing screw 303, which facilitates the disassembly of the handle 301 and the sleeve 201, and is convenient for transportation and replacement. At the same time, the installation hole 302 can play a role in preventing misoperation and identifying the installation direction. After connecting the sleeve 201 and the handle 301, the connection position of the positioning hole 202 and the bean spring 102 can be determined according to the installation hole 302, making the installation more convenient.

[0049] The driving outer tube unit 2 further includes a triangular slide plate 204 arranged on the sleeve 201, far from the handle 301, and used for extruding the bean spring 102.

[0050] In this embodiment, the function of the triangular slide plate 204 is that the bean spring 102 is convex in its natural state, the gap between the sleeve 201 and the insertion rod 101 is small, and the resistance is large when contacting the bean spring 102, so it needs to be manually pressed to lock smoothly. Therefore, arranging the triangular slide plate 204 on the inner wall of the sleeve 201 can make it convenient for the bean spring 102 to slide in without manual pressing.

[0051] The driving outer tube unit 2 further includes a limiting plate 205 arranged on the inner wall of the sleeve 201 and used for resisting the insertion rod 101.

[0052] In this embodiment, the function of the limiting plate 205 is to limit the sleeve 201, to avoid the space existing after the insertion rod 101 is inserted into the sleeve 201. When impacted by an external force, the bean spring 102 is separated from the positioning hole 202, affecting the use experience. At the same time, repeated impacts are likely to damage the bean spring 102, and the limiting plate 205 can remind that the installation is in place and locked.

[0053] A grooved rubber sleeve 4 for clamping the bean spring 102 is arranged on the driving outer tube unit 2.

[0054] In this embodiment, the function of the grooved rubber sleeve 4 is to protect the locked state of the bean spring 102 and prevent the sleeve 201 from being separated after the bean spring 102 is extruded by an external force.
