Description

Technical Field

[0001] The invention belongs to the field of industrial cantilevers, in particular to a cantilever for an industrial display. Background Art

[0002] Currently, existing monitors on the market generally require a support mechanism to support the monitor body;

[0003] The common cantilever lifting support mechanism is a double-link structure. During the rotation process, the angle of the display body relative to the desktop remains fixed, and there are not many display viewing angles for users to choose from. In addition, a locking bolt is usually used to lock the posture and position of the display. Due to the complex factory environment, the posture of the display needs to be frequently adjusted to facilitate viewing and avoid collisions. When adjusting the posture of the display, the locking bolt needs to be turned each time to adjust various posture parameters of the industrial display, including the elevation angle and height. This is time-consuming, labor-intensive and inconvenient. Therefore, a cantilever for an industrial display is proposed. Summary of the Invention

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of this application to avoid obscuring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions should not be used to limit the scope of the present invention.

[0005] In view of the following technical problems in the existing technology: the common cantilever lifting support mechanism is a double-link structure, and the angle of the display body relative to the desktop is fixed during the rotation process, and there are not many display viewing angles for users to choose; and a locking bolt is usually used to lock its posture and position. Due to the complex factory environment, the posture of the display needs to be frequently adjusted to facilitate viewing and avoid collisions. When adjusting the posture of the display, the locking bolt needs to be turned each time to adjust various posture parameters of the industrial display, including elevation and height.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: A cantilever for an industrial display, comprising a supporting mechanism, wherein the supporting mechanism comprises a supporting assembly, a rocking member, an elevation adjustment assembly, a control mechanism and a display assembly, the upper side of the supporting assembly is screwed to the rocking member, the control mechanism is located above the rocking member, and one end of the rocking member is screwed to the display assembly.

[0007] As a preferred technical solution for a cantilever for an industrial display, the support assembly includes a vertical beam and a stabilizing platform. A vertical groove is formed in the middle section of the vertical beam, and the inner bottom wall of the vertical groove is fixedly connected to the lower end of the locking arm.

[0008] The rocking member includes a second connecting column and a transverse arm. The second connecting column is installed on both sides of one end of the transverse arm. The transverse arm passes through the vertical groove of the vertical beam. The second connecting column on the transverse arm is screwed to the vertical beam.

[0009] The support assembly further includes a locking arm, and the rocking member further includes a connecting tube, the connecting tube being disposed at one end of the transverse arm, a connecting column being mounted at the other end of the transverse arm, the connecting column being movably connected to the outer wall of the locking arm, a gap being greater than two millimeters between the vertical surface of the locking arm and the vertical surface of the vertical groove on the vertical beam, the upper side of the stabilizing platform being fixedly connected to the lower side of the vertical beam, and the locking arm being made of elastic steel;

[0010] The elevation adjustment assembly includes a locking column, an elastic member 1, a U-shaped shell, and a connecting column 3. One end of the locking column extends into the U-shaped shell, and the other end of the locking column passes through a clip cylinder. The clip cylinder is movably connected to the locking column. The locking column passes through the elastic member 1. One end of the elastic member 1 abuts the clip cylinder and the other end abuts the U-shaped shell. A connecting column 3 is respectively installed on both sides of the U-shaped shell away from the end of the locking column.

[0011] The control mechanism includes a swing beam, an arc-shaped piece, a connecting beam, two elastic members, and a triangular hammer. The swing beam is provided with an arc-shaped piece at one end, and long straight grooves are respectively provided on both sides of the other end. The top of the connecting beam is movably connected to the swing beam. A connecting beam is respectively provided on both sides of the swing beam. The connecting beam is fixedly connected to the cross arm. The lower sides of the two elastic members are fixedly connected to the swing beam. The elastic members are respectively arranged on both sides of the swing beam. The triangular hammer is paired with the connecting column three.

[0012] The display assembly includes a display, a center column, short columns, and an intermediate beam. A short column is installed on each side of the upper side of the intermediate beam. The center column is connected between the short columns. The outer periphery of the short column abuts against the inner side of the arc-shaped piece. The center column passes through the connecting tube. The center column and the connecting tube are movably connected. The end of the intermediate beam away from the short column is fixedly connected to the display.

[0013] Apply pressure to one end of the triangular hammer on the swing beam to control the swing beam to swing, causing the triangular hammer to move downward without touching the third connecting column. This causes the arc piece to rise and separate from the short column. The short column can move relative to the arc piece and rotate. During this process, the direction of the display is adjusted. Then, the pressure applied to the swing beam is released, and the second elastic member controls the swing beam to restore its original posture, causing the arc piece and the short column to engage and lock again.

[0014] Applying pressure to one end of the triangular hammer on the swing beam controls the swing beam to swing, causing the triangular hammer to move downward and touch the connecting column three. The oblique side of the triangular hammer abuts and presses the connecting column three to move along the extension direction of the cross arm, causing the U-shaped shell to separate from the locking arm with the locking column. Under the pressure of the elastic member one, the locking cylinder forces the locking arm to separate from the locking column, and the locking column is released from the locking arm.

[0015] Then the cross arm can be controlled to swing around the axis of the second connecting column to adjust the elevation angle of the cross arm. After the adjustment is completed, the swing beam is loosened again to connect the locking column with the locking arm to lock the posture of the display.

[0016] As a preferred technical solution for an industrial display cantilever, a locking arm is provided with a plurality of locking holes, which are movably connected to locking posts, and the locking posts extend into the locking holes;

[0017] After the locking post extends into the locking hole, the locking post and the locking arm are locked relative to each other.

[0018] As a preferred technical solution for a cantilever for an industrial display, the swing member further includes a receiving piece. A vertical hole is respectively opened on each side of the horizontal arm. The receiving piece is installed at the bottom of the vertical hole. The upper side of the receiving piece is connected to the second elastic member.

[0019] The connecting piece provides support for the second elastic member so that the connecting piece is indirectly connected to the cross arm.

[0020] As a preferred technical solution for a cantilever for an industrial display, the rocking member further comprises a gasket, which is fixedly connected to the lower side of the cross arm;

[0021] The spacer can raise the height of the middle section of the wishbone.

[0022] As a preferred technical solution for a cantilever for an industrial display, the rocking member further includes a long straight groove, a U-shaped shell is sleeved on the outer periphery of the cross arm, and two opposing inner surfaces of the U-shaped shell are provided with ridges. Long grooves are formed on both sides of the cross arm, and the ridges extend into the long grooves, and the long grooves are movably connected to the ridges.

[0023] The long groove cooperates with the ridge to enable the U-shaped shell to move along the extending direction of the long groove of the cross arm.

[0024] As a preferred technical solution for a cantilever for an industrial display, the control mechanism further includes a safety cover. A safety cover is installed on the outside of each triangular hammer. The upper side of the safety cover is fixedly connected to the swing beam, and a gap is formed between the inner side of the safety cover and the connecting column three.

[0025] The safety cover covers the triangular hammer and the connecting column three to prevent the triangular hammer and the connecting column three from hitting or even clamping human limbs during the mutual movement.

[0026] The number of connecting teeth on the same circumference of the short column outer ring shall not be less than 60.

[0027] The beneficial effects of the cantilever for an industrial display of the present invention are as follows: through the coordinated use of the arc piece and the short column, and through the coordinated use of the swing member, the elevation adjustment assembly and the locking arm, the height and elevation angle of the display can be adjusted to several levels, and the adjustment is very convenient and fast;

[0028] By cooperating with the control mechanism and the elevation adjustment component, the display posture and the elevation angle of the cross arm can be unlocked or locked very conveniently and quickly, thereby greatly improving production efficiency and greatly reducing the difficulty of use;

[0029] When the number of connecting teeth on the same circumference of the outer ring of the short column is not less than 60, and the pitch angle of the rocking member will also change the posture of the display, the diversity of the display's changing orientation will be greatly expanded.

[0043] like Figures 1 to 7 As shown, the present invention proposes a cantilever for an industrial display, including a supporting mechanism 12, wherein the supporting mechanism 12 includes a supporting assembly 13, a rocking member 14, an elevation adjustment assembly 15, a control mechanism 16 and a display assembly. The upper side of the supporting assembly 13 is screwed to the rocking member 14, the control mechanism 16 is located above the rocking member 14, and one end of the rocking member 14 is screwed to the display assembly.

[0044] The supporting assembly 13 includes a vertical beam 19 and a stabilizing platform 20. A vertical groove is formed in the middle of the vertical beam 19, and the inner bottom wall of the vertical groove is fixedly connected to the lower end of the locking arm 18.

[0045] The rocking member 14 includes a second connecting post 22 and a cross arm 23. The second connecting post 22 is installed on both sides of one end of the cross arm 23. The cross arm 23 passes through the vertical groove of the vertical beam 19. The second connecting post 22 on the cross arm 23 is screwed to the vertical beam 19.

[0046] The support assembly 13 further includes a locking arm 18, and the rocking member 14 further includes a connecting tube 24. The connecting tube 24 is disposed at one end of the cross arm 23. A connecting column 21 is mounted at the other end of the cross arm 23. The connecting column 21 is movably connected to the outer wall of the locking arm 18. The clearance between the vertical surface of the locking arm 18 and the vertical surface of the vertical groove on the vertical beam 19 is greater than two millimeters. The upper side of the stabilizing platform 20 is fixedly connected to the lower side of the vertical beam 19. The locking arm 18 is made of elastic steel.

[0047] The elevation adjustment assembly 15 includes a locking column 28, an elastic member 30, a U-shaped shell 31, and a connecting column 32. One end of the locking column 28 extends into the U-shaped shell 31, and the other end of the locking column 28 passes through a clip barrel 29, which is movably connected to the locking column 28. The locking column 28 passes through the elastic member 30. One end of the elastic member 30 abuts the clip barrel 29 and the other end abuts the U-shaped shell 31. A connecting column 32 is respectively installed on both sides of the U-shaped shell 31 away from the end of the locking column 28.

[0048] The control mechanism 16 includes a swing beam 34, an arc-shaped piece 35, a connecting beam 36, a second elastic member 37, and a triangular hammer 38. The arc-shaped piece 35 is mounted on one end of the swing beam 34, and long straight grooves 27 are recessed on both sides of the other end. The top of the connecting beam 36 is movably connected to the swing beam 34. A connecting beam 36 is mounted on each side of the swing beam 34. The connecting beams 36 are fixedly connected to the cross arm 23. The lower sides of the two second elastic members 37 are fixedly connected to the swing beam 34. The second elastic members 37 are arranged on both sides of the swing beam 34. The triangular hammer 38 is paired with the third connecting column 32.

[0049] The display assembly includes a display 17, a center column 39, a short column 40, and an intermediate beam 41. A short column 40 is installed on each side of the upper side of the intermediate beam 41. The center column 39 is connected between the short columns 40. The outer periphery of the short column 40 abuts the inner side of the arc-shaped piece 35. The center column 39 passes through the connecting tube 24 and is movably connected to the connecting tube 24. The end of the intermediate beam 41 away from the short column 40 is fixedly connected to the display 17.

[0050] Connecting teeth are provided on the arc-shaped piece 35 and the short column 40 .

[0051] The swing beam 34 exerts downward pressure on one end where the triangular hammer 38 is located, causing the swing beam 34 to sink and swing, causing the triangular hammer 38 to move downward a certain distance without touching the third connecting post 32. The curved piece 35 at the other end of the swing beam 34 rises and then disengages from the short post 40, allowing the short post 40 to move relative to the curved piece 35. The short post 40 can rotate to adjust the direction of the display 17. Then, the pressure applied to the swing beam 34 is released, and the second elastic member 37 controls the swing beam 34 to return to its original position, causing the curved piece 35 and the short post 40 to contact each other again and then engage and lock.

[0052] Pressure is applied to one end of the triangular hammer 38 on the swing beam 34 to control the swing beam 34 to swing, causing the triangular hammer 38 to move downward and touch the third connecting post 32. The oblique side of the triangular hammer 38 abuts and presses the third connecting post 32 to move along the extension direction of the cross arm 23, causing the U-shaped shell 31 to separate from the locking arm 18 with the locking post 28. Under the pressure of the elastic member 1 30, the locking cylinder 29 forces the locking arm 18 to separate from the locking post 28, and the locking post 28 is released from the locking arm 18.

[0053] Then the cross arm 23 can be controlled to swing around the axis of the second connecting column 22 to adjust the elevation angle of the cross arm 23. After the adjustment is completed, the swing beam 34 is released again to connect the locking column 28 with the locking arm 18, and the posture of the display 17 is locked at the same time.

[0054] The locking arm 18 is provided with a plurality of locking holes, which are movably connected to the locking posts 28, and the locking posts 28 extend into the locking holes;

[0055] After the locking post 28 extends into the locking hole, the locking post 28 and the locking arm 18 are locked relative to each other.

[0056] The rocking member 14 further includes a receiving piece 25. A vertical hole is formed on each side of the cross arm 23. The receiving piece 25 is installed at the bottom of the vertical hole. The upper side of the receiving piece 25 is connected to the second elastic member 37.

[0057] The receiving piece 25 provides support for the second elastic member 37 , so that the receiving piece 25 is indirectly connected to the cross arm 23 .

[0058] The rocker member 14 further includes a gasket 26 , which is fixedly connected to the lower side of the cross arm 23 ;

[0059] The spacer 26 can raise the height of the middle section of the cross arm 23 .

[0060] The rocker 14 further includes a long straight groove 27. A U-shaped shell 31 is sleeved on the outer periphery of the cross arm 23. The inner two opposite surfaces of the U-shaped shell 31 are provided with ridges. Long grooves are formed on both sides of the cross arm 23. The ridges extend into the long grooves. The long grooves and the ridges are movably connected.

[0061] The long groove cooperates with the ridge to enable the U-shaped shell 31 to move along the extending direction of the long groove of the cross arm 23 .

[0062] The control mechanism 16 also includes a safety cover 33. Each triangular hammer 38 is provided with a safety cover 33. The upper side of the safety cover 33 is fixedly connected to the swing beam 34. A gap exists between the inner side of the safety cover 33 and the connecting column 32.

[0063] The safety cover 33 covers the triangular hammer 38 and the connecting column 32 to prevent the triangular hammer 38 and the connecting column 32 from hitting or even clamping a person's limbs during their mutual movement.

[0064] The number of connecting teeth on the same circumference of the outer ring of the short column 40 is not less than 60.

[0065] The specific implementation method is as follows: in order to facilitate viewing of the content on the display 17 and adjust the posture of the display 17, downward pressure is applied to the end of the triangular hammer 38 of the swing beam 34 to control the swing beam 34 to swing, so that the triangular hammer 38 moves downward but does not touch the third connecting column 32, so that the arc piece 35 rises and separates from the short column 40. The short column 40 can move relative to the arc piece 35 and rotate. During this process, the direction of the display 17 is adjusted, and then the pressure applied to the swing beam 34 is released. The second elastic member 37 controls the swing beam 34 to restore its original posture, so that the connecting teeth inside the arc piece 35 and the connecting teeth on the outer ring of the short column 40 are engaged and locked again;

[0066] To accommodate different work needs and people of different heights, the vertical coordinate of the display 17 is adjusted. Pressure is applied to the end of the triangular hammer 38 on the swing beam 34 to control the swing beam 34 to swing, causing the triangular hammer 38 to move downward until it touches the third connecting post 32. The oblique side of the triangular hammer 38 presses the third connecting post 32 along the extension direction of the cross arm 23, causing the U-shaped shell 31 and the locking post 28 to separate from the locking arm 18. Under the pressure of the elastic member 1 30, the locking cylinder 29 forces the locking arm 18 to disengage the locking post 28, and the locking post 28 is released from the locking arm 18.

[0067] Then the cross arm 23 can be controlled to swing around the axis of the second connecting column 22 to adjust the elevation angle of the cross arm 23. After the adjustment is completed, the swing beam 34 is loosened again to allow the locking column 28 to be plugged into the locking arm 18, so that the posture of the display 17 is locked.

[0068] It will be appreciated that in the development of any actual embodiment, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will, for those of ordinary skill having the benefit of this disclosure, be a routine undertaking of design, fabrication, and production without undue experimentation.

[0069] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
