Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for art display, in particular to a track pulley for a display board. Background Technique

[0002] As is well known, when displaying some flat works such as paintings and photos, the works are placed on a display board; the traditional display board is provided with hooks on the back, and then the hooks are hung on the wall fasteners. Although the display board is installed, the position of the display board is fixed and cannot be adjusted anymore. As a result, when replacing exhibits or changing the exhibition layout, it is necessary to remove the wall fasteners, which causes great damage to the wall; or select display boards of the same specification. However, due to the different sizes of the works, it is more wasteful of materials to select display boards of the same specification. To sum up, there is a need for a structure that can conveniently adjust the position of the display board in the current market.

[0003] Therefore, we designed a track pulley for a display board that can cooperate with a slide rail installed on or embedded in a wall to facilitate the adjustment of the position of the display board. Content of the Utility Model

[0004] In order to overcome the deficiencies in the background technique, the utility model discloses a track pulley for a display board.

[0005] To achieve the above-mentioned invention purpose, the utility model adopts the following technical scheme:

[0006] A track pulley for a display board includes a T-shaped slider. Pulley structures are arranged at both the upper and lower ends of the wing part of the T-shaped slider, and the two pulley structures are respectively movably matched with the inner top surface and the inner bottom surface of the track. A hanging groove is arranged at the outer end of the top surface of the abdomen of the T-shaped slider; a through hole is arranged on one side wall of the hanging groove corresponding to the wing part of the T-shaped slider, and a locking rod is slidably penetrated through the through hole cavity. The inner end surface of the locking rod is an inclined surface that is inclined up and down, so that after the hook on the back of the display board is hung into the hanging groove, the locking rod is extruded, and the outer end surface of the locking rod abuts against the inner wall surface of the track to lock the position of the T-shaped slider;

[0007] An elastic extrusion structure for elastically extruding the locking rod is arranged on the wing part of the T-shaped slider, so as to facilitate the movement of the locking rod towards the hanging groove, so that the locking rod is separated from the inner wall surface of the track and the position of the T-shaped slider is conveniently adjusted.

[0008] Preferably, the elastic extrusion structure includes a compression spring sleeved on the rod body of the locking rod and a fixing ring fixedly sleeved on the rod body of the locking rod. One end of the compression spring corresponding to the hanging groove abuts against the fixing ring to elastically extrude the fixing ring and drive the locking rod to move.

[0009] Preferably, the through hole is a stepped hole, a section of the T-shaped slider wing corresponding to the through hole is a large diameter section, the compression spring and the fixing ring are both located correspondingly in the hole cavity of the large diameter section of the through hole, and the outer end of the large diameter section of the through hole is provided with a limiting piece that cooperates with the end of the compression spring away from the fixing ring.

[0010] Preferably, the outer end surface of the T-shaped slider wing is provided with an outer shell body which is sleeved on the locking rod body, and a port of the outer shell body which is away from the T-shaped slider is provided with a reduced diameter portion which matches the locking rod body, and the compression spring and the fixing ring are both located in the inner cavity of the outer shell body.

[0011] Preferably, a friction plate is provided at the outer end of the locking rod.

[0012] Preferably, the pulley structure comprises pulley blocks respectively arranged on both sides of one end of the wing of the T-shaped slider.

[0013] Preferably, the pulley structure includes a pulley block and a V-shaped rotating frame, the pulley block is in the middle of one end of the T-shaped slider wing, the closed end of the V-shaped rotating frame is correspondingly hinged to the end of the T-shaped slider wing, and pulley blocks are provided at both ends of the open end of the V-shaped rotating frame.

[0014] Preferably, the pulley block includes two pulleys respectively located on two sides of the wing of the T-shaped slider.

[0015] Preferably, the V-shaped rotating frame comprises a V-shaped rotating plate symmetrically arranged on both sides of the wing of the T-shaped sliding block, and pulleys are arranged on the outer sides of both ends of the opening end of the V-shaped rotating plate.

[0016] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0017] 1. The display board can move along the track axis with the T-shaped slider to adjust the position of the display board. The T-shaped slider can also adjust the position according to the position of the hook on the back of the display board to adapt to display boards of different sizes.

[0018] 2. The weight of the display board can cause the hook on the back to squeeze the locking rod, so that the locking rod moves axially and contacts the inner wall of the track, thereby locking the position of the T-shaped slider and increasing the stability of the display board. When the display board is not mounted, the locking rod is separated from the inner wall of the track by the elastic squeezing structure, which facilitates the adjustment of the position of the T-shaped slider.

[0019] 3. The setting of the V-shaped rotating frame can enable the V-shaped rotating frame to rotate when the slide rail has flatness defects due to manufacturing, installation and other tolerances, so that the pulley can drive over the unevenness, ensuring the smooth movement of the T-shaped slider and preventing the T-shaped slider from getting stuck or even getting stuck due to flatness defects in the slide rail due to manufacturing, installation and other tolerances.

[0028] Embodiment 1, in combination with the attached Figure 1-6 , a track pulley for a display board, including a T-shaped slider 1. Pulley structures 2 are provided at both the upper and lower ends of the wing part of the T-shaped slider 1, and the two pulley structures 2 are respectively movably fitted to the inner top surface and the inner bottom surface of the track. A hanging groove 11 is provided at the outer end of the top surface of the abdomen of the T-shaped slider 1; specifically, the outer end of the abdomen of the T-shaped slider 1 extends out of the track groove, and the hanging groove 11 is correspondingly located outside the track, so that the hook on the back of the display board can be hung into the hanging groove 11.

[0029] This arrangement enables the display board to move along the track axis with the T-shaped slider 1, thereby adjusting the position of the display board. The T-shaped slider 1 can also adjust the position according to the position of the hook on the back of the display board, thus being suitable for display boards of different sizes.

[0030] A through hole 12 is provided on one side wall of the hanging groove 11 corresponding to the wing of the T-shaped slider 1, and a locking rod 3 is slidably penetrated through the through hole 12, and the inner end surface of the locking rod 3 is an inclined surface inclined up and down, so that the hook on the back of the display board is hung in the hanging groove 11 and the locking rod 3 is squeezed, so that the outer end surface of the locking rod 3 contacts the inner wall surface of the track to lock the position of the T-shaped slider 1;

[0031] As required, the locking rod 3 can only move axially in the through hole 12 and cannot rotate.

[0032] The wing of the T-shaped slider 1 is provided with an elastic extrusion structure 4 for elastically extruding the locking rod 3, so that the locking rod 3 can move toward the hanging groove 11, so that the locking rod 3 is separated from the inner wall of the track and the position of the T-shaped slider 1 can be adjusted conveniently.

[0033] This arrangement can use the gravity of the exhibition board to make the hook on the back squeeze the locking rod 3, so that the locking rod 3 moves axially and contacts the inner wall of the track, thereby realizing the function of locking the position of the T-shaped slider 1, increasing the stability of the exhibition board, and when the exhibition board is not hung, the locking rod 3 is in a separated state from the inner wall of the track under the action of the elastic squeezing structure 4, which facilitates the adjustment of the position of the T-shaped slider 1.

[0034] Furthermore, the elastic extrusion structure 4 includes a compression spring 41 matched with the rod body of the locking rod 3 and a fixing ring 42 fixedly mounted on the rod body of the locking rod 3. One end of the compression spring 41 corresponding to the hanging groove 11 abuts against the fixing ring 42 to elastically squeeze the fixing ring 42 to drive the locking rod 3 to move.

[0035] Furthermore, in order to increase the stability of the position of the T-shaped slider 1 after the display board is hung, a friction plate 5 is provided at the outer end of the locking rod 3.

[0036] To ensure that the compression spring 41 has elastic extrusion properties on the fixing ring 42:

[0037] In a possible embodiment, in combination with the attached Figure 4 The through hole 12 is a stepped hole. A section of the wing of the T-shaped slider 1 corresponding to the through hole 12 is a large diameter section. The compression spring 41 and the fixing ring 42 are both located in the cavity of the large diameter section of the through hole 12. The outer end of the large diameter section of the through hole 12 is provided with a limit piece 13 that abuts against one end of the compression spring 41 away from the fixing ring 42.

[0038] In another possible embodiment, Figure 3, an outer end surface of a wing portion of the T-shaped slider 1 is provided with a housing 14 sleeved on the rod body of the locking rod 3. One end port of the housing 14 facing away from the T-shaped slider 1 is provided with a reduced-diameter portion matching the rod body of the locking rod 3. The compression spring 41 and the fixing ring 42 are both located in the inner cavity of the housing 14.

[0039] To ensure the stability of the position of the T-shaped slider 1:

[0040] In a possible embodiment, in combination with the attached Figure 6 , the pulley structure 2 includes pulley groups 21 respectively arranged on both sides of one end of the wing portion of the T-shaped slider 1; as required, the pulley group 21 includes two pulleys 211 respectively corresponding to both sides of the wing portion of the T-shaped slider 1.

[0041] In another possible embodiment, in combination with the attached Figure 1-5 , the pulley structure 2 includes a pulley group 21 and a V-shaped rotating frame 22. The pulley group 21 is in the middle of one end of the wing portion of the T-shaped slider 1. The closed end of the V-shaped rotating frame 22 is correspondingly hinged to this end of the wing portion of the T-shaped slider 1, and pulley groups 21 are provided at both ends of the open end of the V-shaped rotating frame 22; as required, the pulley group 21 includes two pulleys 211 respectively corresponding to both sides of the wing portion of the T-shaped slider 1.

[0042] With such a setting, when the slide rail has flatness defects due to manufacturing, installation and other tolerances, the rotation of the V-shaped rotating frame 22 can be achieved, so that the pulley 211 can cross the uneven drive, ensuring the smooth movement of the T-shaped slider 1 and preventing the T-shaped slider 1 from jamming or even being stuck due to the flatness defects of the slide rail caused by manufacturing, installation and other tolerances.

[0043] Furthermore, in combination with the attached Figure 1 , the V-shaped rotating frame 22 includes V-shaped rotating plates 221 symmetrically arranged on both sides of the wing portion of the T-shaped slider 1, and pulleys 211 are provided on the outer sides of both ends of the open end of the V-shaped rotating plate 221.

[0044] As required, the two V-shaped rotating plates 221 in the same V-shaped rotating frame 22 can rotate synchronously or asynchronously.

[0045] For example, when the two V-shaped rotating plates 221 in the same V-shaped rotating frame 22 rotate synchronously, a pin shaft can be fixedly installed between the closed ends of the two V-shaped rotating plates 221, and the rotation connection with one end of the wing portion of the T-shaped slider 1 is realized through this pin shaft.

[0046] When the two V-shaped rotating plates 221 in the same V-shaped rotating frame 22 rotate asynchronously, a pin shaft is rotatably connected to the closed end of each of the two V-shaped rotating plates 221, and this pin shaft is correspondingly connected to one end of the wing portion of the T-shaped slider 1. Here, the corresponding connection can be a fixed connection or a rotating connection; it is specifically designed according to actual needs and is not specifically limited here.

[0047] The parts not detailed in this utility model are prior art. For those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive, aiming to encompass all changes falling within the meaning and scope of equivalent elements in this utility model.
