[0002] With the development of display technology, users have increasingly diverse needs for monitor support devices. Among them, support devices with lifting functions are gaining popularity. Traditional support devices with lifting functions typically include a fixed sleeve, a constant force spring located within the fixed sleeve, and a sliding component located within the fixed sleeve and supporting the constant force spring. However, the traditional assembly structure of the sliding component and the fixed sleeve is usually fixed with screws. Specifically, a lower connecting component is connected to the upper sliding component by screws, and a limiting cylinder is fixedly connected to the top of the lower sleeve. The upper sliding component is inserted into the limiting cylinder, and the lower connecting component moves upward with the upper sliding component until it abuts against the bottom end face of the limiting cylinder, thus achieving the limiting effect of the limiting cylinder. In traditional lifting components, the assembly of the upper sliding component, lower connecting component, lower sleeve, and limiting cylinder is quite difficult. Summary of the Invention

[0003] The main objective of this invention is to provide a lifting assembly that reduces the difficulty of assembling the lifting assembly.

[0004] To achieve the above objectives, the present invention proposes a lifting assembly comprising a fixed sleeve, a constant force spring, and a sliding member; one end of the constant force spring is fixedly connected to the fixed sleeve, and the other end is retractable within the fixed sleeve; the sliding member is slidably disposed within the fixed sleeve and abuts against the other end of the constant force spring; a slot is also formed within the fixed sleeve, the slot having an insertion port on the end face of the fixed sleeve; one end of the sliding member extending into the fixed sleeve is also provided with a limiting protrusion; the lifting assembly further includes a pin, the pin being inserted from the insertion port into the slot and engaging with the slot, and the pin and the limiting protrusion abutting against each other in the sliding direction of the sliding member to limit the sliding member from disengaging from the fixed sleeve.

[0005] In one embodiment, the latch includes:

[0006] The main body, inserted into the slot, abutting against at least one wall of the slot; and

[0007] An elastic piece, one end of which is fixedly connected to the main body, and the other end extends in a direction away from the insertion port; a lifting protrusion is provided on the groove wall of the slot away from the slider, the lifting protrusion abuts against the elastic piece, and the elastic piece and the limiting protrusion abut against each other in the sliding direction of the slider.

[0008] In one embodiment, the main body has an opening for clearance, one end of the elastic piece is located inside the opening for clearance and is connected to the inner wall of the opening for clearance;

[0009] And / or, the end face of the body inserted into the slot is a guide slope.

[0010] In one embodiment, the body includes:

[0011] Insert, the insert being inserted into the slot, one end of the elastic piece being fixedly connected to the insert; and

[0012] A flexible locking arm, one end of which is connected to the end of the insert that extends into the slot, the other end of which extends toward the insertion port and forms a gap with the insert, and the flexible locking arm abuts against at least one wall of the slot.

[0013] In one embodiment, one of the slot wall and the elastic locking arm is provided with a buckle hole, and the other is provided with a buckle that engages with the buckle hole.

[0014] In one embodiment, the resilient locking arm extends out of the slot.

[0015] In one embodiment, the end of the elastic locking arm extending out of the slot is provided with a lug, and the lug abuts against the end face of the fixing sleeve where the insertion port is located;

[0016] And / or, one end of the insert is inserted into the slot, and the other end is located outside the slot, with a handle hole provided at the end of the insert located outside the slot.

[0017] The present invention also proposes an assembly method based on the above-described lifting component, the assembly method comprising:

[0018] The constant force spring is fixed inside the fixed sleeve;

[0019] Insert the slider into the fixed sleeve and move the slider against the constant force spring to a first position, and keep it in the first position;

[0020] Insert the pin into the slot of the fixing sleeve and insert it to the second position;

[0021] Release the slider so that it automatically moves toward the pin under the force of the constant force spring and abuts against the pin.

[0022] The present invention also proposes a support device, including a head mounting structure and the above-mentioned lifting assembly, wherein the head mounting structure is connected to the end of the sliding member that does not extend into the fixed sleeve.

[0024] The technical solution of this invention fixes one end of a constant force spring to a fixed sleeve, allowing the spring to extend and retract within the sleeve. A sliding member is slidably positioned within the fixed sleeve and abuts against the other end of the spring, enabling the sliding member to rise under the spring's action and providing good positioning during descent. A slot is also formed within the fixed sleeve, with an insertion port on the end face of the sleeve. A pin can be inserted into the slot through this port to connect the sliding member to the fixed sleeve. A limiting protrusion is also provided on the outer wall of the sliding member. When the pin is inserted into the slot and engages with it, the pin and the limiting protrusion abut against each other in the sliding direction of the sliding member, providing a good limiting effect when the pin disengages from the fixed sleeve, thus effectively achieving the connection between the sliding member and the fixed sleeve. The connection between the sliding component and the fixed sleeve is achieved simply by inserting the sliding component into the fixed sleeve and inserting the pin into the slot. There is no need to use a locking method, which makes the assembly process of the sliding component and the fixed sleeve simpler, easier, and more efficient. Attached Figure Description

[0043] Example 1:

[0044] This invention proposes a lifting assembly.

[0045] In the embodiments of the present invention, please refer to the reference. Figures 1 to 8 The lifting assembly includes a fixed sleeve 100, a constant force spring 200, and a sliding member 300. One end of the constant force spring 200 is fixedly connected to the fixed sleeve 100, and the other end can extend and retract within the fixed sleeve 100. The sliding member 300 is slidably disposed within the fixed sleeve 100 and abuts against the other end of the constant force spring 200. A slot 110 is also formed within the fixed sleeve 100. The slot 110 has an insertion port 111 opened on the end face of the fixed sleeve 100. One end of the sliding member 300 extending into the fixed sleeve 100 is also provided with a limiting protrusion 310. The lifting assembly also includes a pin 400. The pin 400 is inserted into the slot 110 from the insertion port 111 and engages with the slot 110. The pin 400 and the limiting protrusion 310 abut against each other in the sliding direction of the sliding member 300 to limit the sliding member 300 when it is disengaged from the fixed sleeve 100.

[0046] In the lifting assembly, the fixed sleeve 100 can serve as either the upper sliding member 300 or the lower sleeve. When the fixed sleeve 100 serves as the lower sleeve, the sliding member 300 can serve as the upper sliding member 300. The following explanation uses the fixed sleeve 100 as the lower sleeve and the sliding member 300 as the upper sliding member 300 as an example.

[0047] By fixing one end of the constant force spring 200 inside the fixed sleeve 100, and allowing the other end to extend and retract within the fixed sleeve 100, a constant force support effect can be achieved for the sliding member 300 during its sliding process. The constant force spring 200 can be connected to the fixed sleeve 100 via a snap-fit ​​connection or a screw connection, as long as one end of the constant force spring 200 can be connected to the fixed sleeve 100. It is understood that, to facilitate the insertion of the sliding member 300 into the fixed sleeve 100, the fixed sleeve 100 must at least have a sliding cavity 130 for the sliding member 300 to be inserted and slide. The sliding cavity 130 has an inlet for the sliding member 300 to be inserted, and the constant force spring 200 is disposed within this sliding cavity 130. In this invention, a slot 110 is formed inside the fixed sleeve 100, and the slot 110 has an insertion port 111 on the end face of the fixed sleeve 100, allowing the pin 400 to be inserted into the slot 110 through the insertion port 111. Furthermore, by having the pin 400 and the limiting protrusion 310 on the slider 300 abut against each other in the sliding direction of the slider 300, a limiting basis is provided for the slider 300 to be ejected from the fixed sleeve 100 under the elastic force of the constant force spring 200, thereby achieving the effect of connecting the fixed sleeve 100 and the slider 300. For ease of installation, the insertion port 111 and the entrance of the sliding cavity 130 are located on the same end face of the fixed sleeve 100, thus achieving the effect of inserting both the slider 300 and the pin 400 into the fixed sleeve 100 without flipping the fixed sleeve 100. Furthermore, by engaging the pin 400 with the slot 110, the pin 400 will not easily pop out of the slot 110 due to the resistance of the slider 300. It should be noted that the engagement between the pin 400 and the slot 110 can be a snap-fit ​​connection or an interference fit. Understandably, when the pin 400 and the slot 110 are in an interference fit, the friction at their contact surfaces is greater, which can counteract the resistance of the slider 300, thereby reducing the risk of the pin 400 popping out of the slot 110.

[0048] The following describes the assembly process of the lifting assembly: First, fix the constant force spring 200 inside the fixed sleeve 100, at which point the constant force spring 200 is in its natural state; then, insert the sliding member 300 into the fixed sleeve 100 so that the sliding member 300 abuts against the constant force spring 200, and push the sliding member 300 so that the sliding member 300 and the elastic end of the constant force spring 200 move downward together a certain distance. At this time, keep the state of the constant force spring 200 and the sliding member 300 unchanged, that is, keep the constant force spring 200 in its natural state. The device is in a compressed state. Next, the pin 400 is inserted into the insertion slot through the insertion port 111. At this time, at least a portion of the pin 400 corresponds to the limiting protrusion 310 of the slider 300 in the vertical direction (i.e., the sliding direction of the slider 300). Finally, the slider 300 is released. At this time, the slider 300 moves upward under the action of the constant force spring 200 until the limiting protrusion 310 of the slider 300 and the pin 400 abut against each other in the vertical direction. This completes the assembly process of the lifting assembly. During this assembly process, the user only needs to perform two insertion actions when connecting the slider 300 to the lifting assembly: inserting the slider 300 into the fixing sleeve 100 and inserting the pin 400 into the slot 110 of the slider 300. No locking operation is required. Therefore, the assembly operation of the lifting assembly is simplified, the assembly difficulty is reduced, the assembly efficiency of the lifting assembly is improved, and the risk of damage to the various parts of the lifting assembly is reduced.

[0049] When it is necessary to disassemble or assemble the lifting assembly, simply pull the pin 400 out of the slot 110 first, and then pull the sliding part 300 out of the fixed sleeve 100. This simplifies the disassembly and assembly of the lifting assembly, reduces the difficulty of disassembly and assembly, improves the efficiency of disassembly and assembly, and also reduces the risk of damage to various parts of the lifting assembly.

[0050] The technical solution of this invention fixes one end of a constant force spring 200 to the fixed sleeve 100, while the other end of the constant force spring 200 can extend and retract within the fixed sleeve 100. A sliding member 300 is slidably disposed within the fixed sleeve 100 and abuts against the other end of the constant force spring 200. This allows the sliding member 300 to rise under the action of the constant force spring 200, and also provides a good positioning effect during descent. Furthermore, a slot 110 is formed within the fixed sleeve 100, with an insertion port 111 on the end face of the fixed sleeve 100. A pin 400 can be inserted from this insertion port 111 into the slot 110 to facilitate the connection between the sliding member 300 and the fixed sleeve 100. The outer wall of the slider 300 is also provided with a limiting protrusion 310. When the pin 400 is inserted into the slot 110 and engages with the slot 110, the pin 400 and the limiting protrusion 310 abut against each other in the sliding direction of the slider 300. This provides a good limiting effect when the pin 400 disengages from the fixed sleeve 100, thereby effectively achieving the connection between the slider 300 and the fixed sleeve 100. During the connection process between the slider 300 and the fixed sleeve 100, only two insertion operations are required: inserting the slider 300 into the fixed sleeve 100 and inserting the pin 400 into the slot 110. No locking method is needed, making the assembly process of the slider 300 and the fixed sleeve 100 simpler, easier, and more efficient.

[0051] In one example, please refer to the reference. Figure 2 , Figure 3 , Figures 5 to 8 The pin 400 includes a body 410 and a spring piece 420. The body 410 is inserted into the slot 110 and abuts against at least one wall of the slot 110. One end of the spring piece 420 is fixedly connected to the body 410, and the other end extends in a direction away from the insertion port 111. A lifting protrusion 120 is provided on the slot wall away from the slider 300. The lifting protrusion 120 abuts against the spring piece 420, and the spring piece 420 and the limiting protrusion 310 abut against each other in the sliding direction of the slider 300.

[0052] By inserting the body 410 of the pin 400 into the slot 110, and having the body 410 abut against at least one wall of the slot 110, the friction between the body 410 and the wall of the slot 110 can be increased, reducing the risk of the pin 400 dislodging from the slot 110. By fixing one end of the elastic piece 420 to the body 410 and extending the other end in a direction away from the insertion port 111, the elastic piece 420 can deform in the direction perpendicular to the insertion of the pin 400, that is, in the sliding direction perpendicular to the sliding member 300. By providing a lifting protrusion 120 on the groove wall of the slot 110 away from the slider 300, that is, by providing a lifting protrusion 120 on the groove wall of the slot 110 near the outer side wall of the fixed sleeve 100, when the pin 400 is inserted into the slot 110, the elastic piece 420 can deform towards the slider 300 under the resistance of the lifting protrusion 120. This makes it easier for the elastic piece 420 to resist the limiting protrusion 310 of the slider 300 when the slider 300 moves upward, thereby providing a better limiting effect on the upward movement of the slider 300 and reducing the risk of the slider 300 coming out of the fixed sleeve 100.

[0053] With this configuration, there is no need to drive the elastic piece 420 to deform by setting a separate driving component, and there is also no need for the user to pull the elastic piece 420 towards the sliding member 300. This not only makes the connection between the sliding member 300 and the fixed sleeve 100 in the lifting assembly of the present invention more stable, but also further reduces the assembly difficulty of the sliding member 300 and the fixed sleeve 100.

[0054] Specifically, the main body 410 may be a single insert 411 structure, with the insert 411 and the slot 110 having an interference fit; or the main body 410 may also include a snap-fit ​​structure on the insert 411 to facilitate a snap-fit ​​connection with the slot 110. To reduce the possibility of the spring piece 420 and the lifting protrusion 120 getting stuck when the pin 400 is inserted into the slot 110, the surface of the lifting protrusion 120 facing the insertion port 111 may be configured as a guide slope 411b, or the free end of the spring piece 420 may be configured as an arc shape, with the free end of the spring piece 420 tilted towards the insertion port 111.

[0055] In one example, please refer to the reference. Figure 5 or Figure 6 The main body 410 has an opening 411a, one end of the elastic piece 420 is located inside the opening 411a and is connected to the inner wall of the opening 411a.

[0056] This configuration allows the entire surface of the elastic piece 420 facing away from the sliding member 300 to face the lifting protrusion 120, thus facilitating the lifting protrusion 120 to support the elastic piece 420 and cause it to deform. On the other hand, it also reduces the weight and material cost of the pin 400.

[0057] Of course, in other examples, the body 410 may not have an opening 411a. The elastic piece 420 may be connected to the side of the body 410 facing the slider 300 or to the side of the body 410 away from the slider 300, and the elastic piece 420 may be located at least partially below the bottom end of the body 410.

[0058] Furthermore, such as Figure 6 As shown, the end face of the main body 410 inserted into the slot 110 is a guide slope 411b.

[0059] By setting the end face of the part of the main body 410 that is inserted into the slot 110 as a guide slope 411b, it is easier for the main body 410 to be smoothly inserted into the slot 110, reducing the risk of the main body 410 getting stuck with the slot wall of the slot 110.

[0060] Specifically, based on the design of providing a clearance opening 411a on the main body 410, the end face of the main body 410 inserted into the slot 110 is a guide slope 411b. This can be achieved by setting the outer surface of the bottom edge of the clearance opening 411a away from the insertion port 111 as the guide slope 411b. In addition, to facilitate the removal of the pin 400 from the slot 110, the projection of the bottom edge of the clearance opening 411a in the plane perpendicular to the sliding direction of the slider 300 does not coincide with the projection of the limiting protrusion 310 and the projection of the lifting protrusion 120. This ensures that when the pin 400 is pulled out of the slot 110, neither the limiting protrusion 310 nor the lifting protrusion 120 will interfere with the bottom edge of the clearance opening 411a.

[0061] In one example, please refer to the reference. Figure 2 , Figure 4 , Figures 5 to 7 The main body 410 includes an insert 411 and an elastic locking arm 412. The insert 411 is inserted into the slot 110, and one end of the elastic piece 420 is fixedly connected to the insert 411. One end of the elastic locking arm 412 is connected to the end of the insert 411 that extends into the slot 110, and the other end of the elastic locking arm 412 extends toward the insertion port 111 and forms a gap with the insert 411. The elastic locking arm 412 abuts against at least one groove wall of the slot 110.

[0062] The spring clip serves as the connecting base for the elastic piece 420. By connecting one end of the elastic locking arm 412 to the main body 410 and extending the other end toward the insertion port 111, forming a gap between it and the main body 410, and by having the elastic locking arm 412 abut against at least one groove wall of the slot 110, the pin 400 abuts against the groove wall of the slot 110 through the elasticity of the elastic locking arm 412 itself. This increases the friction between the pin 400 and the groove wall of the slot 110, reducing the risk of the pin 400 being ejected when the slider 300 moves upward. In addition, by providing the elastic locking arm 412, when the pin 400 is pulled out of the slot 400, the user deforms the elastic locking arm 412 toward the insertion piece 411, thereby forming a gap between the elastic locking arm 412 and the groove wall of the slot 110, which facilitates a smoother removal of the pin 400 from the slot 400.

[0063] Specifically, the deformation direction of the elastic locking arm 412 can be the same as or perpendicular to the deformation direction of the elastic piece 420. There may be one elastic locking arm 412. Alternatively, there may be two elastic locking arms 412, each positioned on opposite sides of the insert 411. With this arrangement, the user can pinch the two elastic locking arms 412 with their thumb and forefinger, causing both arms to deform towards the insert 411, thus disengaging from the groove wall of the slot 110. Simultaneously, lifting the elastic locking arms 412 upwards will dislodge the pin 400 from the slot 110.

[0064] Furthermore, please refer to the following: Figure 2 , Figure 4 , Figures 5 to 7 The elastic arm 412 has a buckle 413 on the side away from the insert 411, and the slot wall of the slot 110 has a corresponding buckle hole 112, and the buckle 413 is inserted into the buckle hole 112.

[0065] By providing a latch 413 on the side of the elastic arm 412 away from the insert 411, and correspondingly providing a latch hole 112 on the groove wall of the slot 110, the latch 413 engages with the latch hole 112, further improving the stability of the insert 411 within the slot 110. This avoids the risk of the slider 300 moving upward and abutting against the elastic piece 420, causing the insert 411 to dislodge from the slot 110. Furthermore, this design also produces a clicking sound when the latch 413 engages with the latch hole 112, thus providing a confirmation to the user that the pin 400 is fully inserted into the slot 110, preventing the user from inserting the pin 400 too deeply.

[0066] Understandably, when it is necessary to remove the pin 400 from the slot 110, the user only needs to pinch the elastic locking arm 412 so that the elastic locking arm 412 moves towards the insert 411. This not only creates a gap between the elastic locking arm 412 and the slot wall of the slot 110, but also disengages the latch 413 from the latch hole 112, thereby facilitating the smooth removal of the pin 400 from the slot 110.

[0067] Of course, in other examples, the elastic locking arm 412 can also have a snap hole 112 on the side away from the insert 411, and the slot wall of the slot 110 can have a corresponding snap 413, which snaps into the snap hole 112. It should be noted that this setting has the same effect as the above-mentioned setting where "the elastic locking arm 412 has a snap 413 on the side away from the insert 411, and the slot wall of the slot 110 has a corresponding snap hole 112, which snaps into the snap hole 112".

[0068] To facilitate the removal of the drive pin 400 from the slot 110, please refer to the following: Figure 1 , Figure 5 and Figure 6 The flexible locking arm 412 extends out of the slot 110.

[0069] By extending the elastic locking arm 412 out of the slot 110, it is easier for the user to pinch the elastic locking arm 412, thereby making it easier to drive the elastic locking arm 412 away from the slot wall of the slot 110, so that it can be pulled out from the slot 110 more smoothly.

[0070] Furthermore, please refer to the following: Figure 1 , Figure 2 as well as Figure 4 The end of the elastic locking arm 412 that extends out of the slot 110 is provided with a lug 414, which abuts against the end face of the fixing sleeve 100 that is provided with an insertion port 111.

[0071] By providing a lug 414 at one end of the elastic locking arm 412 that extends out of the slot 110, and having the lug 414 abut against the end face of the fixed sleeve 100 with the insertion port 111, the fixed sleeve 100 and the lug 414 can be mutually limited, thereby avoiding the risk that the entire pin 400 will be inserted into the slot 110 and the pin 400 will be difficult to pull out later.

[0072] To facilitate the insertion of the pin 400 into the slot 110, one end of the insert 411 is inserted into the slot 110, and the other end is located outside the slot 110. The end of the insert 411 located outside the slot 110 has a handle hole 411c.

[0073] By providing a handle hole 411c at one end of the insert 411 outside the slot 110, the user can insert the pin 400 into the slot 110 by holding the handle hole 411c, thereby improving the convenience of user operation.

[0074] Example 2:

[0075] This invention also proposes an assembly method for a lifting component. This assembly method is based on the aforementioned lifting component, the specific structure of which is described in the above embodiments. Since this assembly method employs all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here. Please refer to [reference needed]. Figures 1 to 9 The assembly method of the lifting component includes:

[0076] Step 10: Fix the constant force spring 200 inside the fixed sleeve 100.

[0077] When the constant force spring 200 is installed inside the fixed sleeve 100, it can be achieved through screw connection, snap-fit ​​connection, or welding. The installation of the constant force spring 200 provides a supporting foundation for the subsequent insertion of the sliding component 300 into the fixed sleeve 100.

[0078] Step 20: Insert the slider 300 into the fixed sleeve 100 and move the slider 300 against the constant force spring 200 to the first position and maintain it in the first position.

[0079] One end of the slider 300 inserted into the fixed sleeve 100 has a structure adapted to the force spring 200, such as an arc-shaped groove structure adapted to the winding portion of the force spring 200. When installing the slider 300, the user inserts the end of the slider 300 adapted to the force spring 200 into the fixed sleeve 100, so that the slider 300 and the force spring 200 abut against each other. Then, the user can push the slider 300 deeper into the fixed sleeve 100, at which time the slider 300 drives the force spring 200 to elastically stretch. When the slider 300 abuts against the force spring 200 and moves to the first position, the user can hold the slider 300 with one hand to keep it in the first position. The first position in this invention refers to the position that can avoid the subsequent insertion of the pin 400 into the slot 110, that is, the limiting protrusion 310 of the slider 300 is located after the pin 400 is inserted into the slot 110, and the part of the pin 400 used to abut against the limiting protrusion 310 can be located above the limiting protrusion 310.

[0080] Step 30: Insert the pin 400 into the slot 110 of the retaining sleeve 100 and insert it to the second position.

[0081] When the pin 400 is inserted into the slot 110 of the fixed sleeve 100, the user only needs to operate with one hand. When the pin 400 is inserted into the second position, it proves that the pin 400 is inserted in place. The insertion of the pin 400 provides a good limiting effect for the upward movement of the slider 300, thereby reducing the risk that the slider 300 may easily fall out of the fixed sleeve 100, and providing a connection basis for the stable connection of the slider 300 to the fixed sleeve 100.

[0082] Step 40: Release the slider 300 so that the slider 300 automatically moves towards the pin 400 under the elastic force of the constant force spring 200 and abuts against the pin 400.

[0083] After the slider 300 is released, it is no longer supported by the spring force of the constant force spring 200 used by the user. At this time, the slider 300 loses its balance and will return upward under the action of the spring force spring 200. It will stop when it returns to abutting the pin 400. At this time, the process of installing the slider 300 on the fixed sleeve 100 is completed.

[0084] In this invention, after fixing the constant force spring 200 inside the fixed sleeve 100, the sliding member 300 is inserted into the fixed sleeve 100 to support the constant force spring 200 and move it to a first position. After maintaining this first position, the pin 400 is inserted into the slot 110 of the fixed sleeve 100. This simple plug-in connection connects the fixed sleeve 100 and the sliding member 300, reducing the cumbersome operation of screw fastening and making the assembly process simpler and more convenient. Of course, when it is necessary to separate the fixed sleeve 100 and the sliding member 300, simply pulling out the pin 400 removes the sliding member 300 from the fixed sleeve 100. The assembly and disassembly of this lifting assembly are relatively easy.

[0085] Example 3:

[0086] The present invention also proposes a support device, such as... Figure 10 As shown, the support device includes a head mounting structure 500 and a lifting assembly. The specific structure of the lifting assembly is as described in the above embodiments. Since this support device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The head mounting structure 500 is connected to the end of the sliding member 300 that does not extend into the fixed sleeve 100.

[0087] The head mounting structure 500 of the support device is used to mount the display. By mounting the display on the head mounting structure 500, and connecting the head mounting structure 500 to the end of the slider 300 that does not extend into the fixed sleeve 100, the display can be raised and lowered in the vertical direction along with the head mounting structure 500 and the slider 300, thereby achieving the effect of adjusting the height of the display.

[0088] Example 4:

[0089] The present invention also proposes a display device, such as Figure 11 As shown, the display device includes a display 600 and a support device. The specific structure of the support device is as described in the above embodiments. Since this display device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The display is mounted on the head mounting structure 500.

[0090] By mounting the display on the head-mounting structure 500, the display can be raised and lowered by the lifting component along with the head-mounting structure 500, thus achieving the effect of adjusting its height.

[0091] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
