Description

Technical Field

[0001] This utility model relates to the field of display device technology, specifically a display device for product art design. Background Technology

[0002] In product demonstrations, warning tape is typically placed around the booth to protect exhibited products from accidental damage caused by visitors. While traditional warning tape, which is widely used, provides some degree of isolation, it has several significant drawbacks. First, the installation and removal of traditional tape requires cumbersome operations, such as repeated bundling, unbundling, and securing. This not only consumes considerable time and manpower but can also disrupt the demonstration if handled improperly. Second, when not in use, the tape requires dedicated storage space, which is undoubtedly a waste of resources in exhibition spaces with limited space. Utility Model Content

[0003] To address the technical problems in the background art, this utility model discloses a display device for product art design.

[0004] This utility model provides a product art design display device, which consists of a display stand, a support column and a base connected from top to bottom, and at least three rotationally symmetrical telescopic rods are hinged on the support column;

[0005] The telescopic rod consists of an outer cylinder, several middle cylinders, and an inner cylinder arranged sequentially from the outside to the inside.

[0006] A compression spring is installed inside the inner cylinder. When the compression spring is in its free state, the telescopic rod is in the extended state.

[0007] The opening and closing end of the inner cylinder is equipped with a warning tape, one end of which is fixed to the inner cylinder and the other end is floating, used to lock the adjacent inner cylinder.

[0008] The beneficial effects of the above design are: 1. The telescopic pole is hinged to the support column. When it rotates to be parallel to the support column, it is retracted. When it is extended to the horizontal, it is engaged with the adjacent telescopic pole by the warning tape, so that the telescopic pole and the warning tape form a circular warning area, preventing visitors from touching the exhibits. This not only makes the warning tape easy to install and remove, but also eliminates the storage space required for traditional warning lines. 2. The compression spring supports the telescopic pole, keeping it in the extended state, thereby improving the stability of the connection structure of the warning tape.

[0009] Since the position of the telescopic rod is not fixed, it is difficult to play an effective blocking role. Based on this, a further improvement is made: a storage groove is provided on the side of the support column; the telescopic rod is hinged to the upper part of the bottom of the storage groove, and when the telescopic rod rotates to the horizontal state, its upper side abuts against the upper wall of the storage groove.

[0010] Since the telescopic pole's natural state is extended, if its length exceeds the support column's length, it becomes difficult to retract. Therefore, a further improvement is made: the length of the storage slot is greater than or equal to the retracted length of the telescopic pole. With this design, the retracted pole is blocked by the lower wall of the storage slot, thus maintaining stability in its retracted state.

[0011] Because the telescopic rod is placed in the storage slot and its position is unstable, and its position is also unstable when the telescopic rod is extended, a further improvement is made: the area where the storage slot is opened on the support column is provided with external threads, and a limit sleeve is threadedly connected to it; when the telescopic rod extends, it is clamped between the limit sleeve and the upper wall of the storage slot; when the telescopic rod is retracted, it is limited to the bottom of the storage slot and the inner wall of the limit sleeve.

[0012] When the telescopic rod is removed from the storage slot, it will quickly pop out under the action of the compression spring, which can easily cause injury to the human body. Based on this, a further improvement is made: a baffle is installed inside the inner cylinder, and its outer wall is sealed to the inner wall of the inner cylinder; the inner cylinder and the middle cylinder are sealed together; adjacent middle cylinders are sealed together; the middle cylinder and the outer cylinder are sealed together; and the baffle is provided with air holes. In this arrangement, the baffle, inner cylinder, middle cylinder and outer cylinder form a closed space, which is connected to the outside world only through the air holes; when the inner cylinder extends outward, due to the small flow area of ​​the air holes, the air pressure in this space is difficult to quickly balance with the outside, thus forming a negative pressure in this space, thereby resisting the extension shape of the inner cylinder and reducing the extension speed of the inner cylinder.

[0013] To facilitate the storage of the warning tape when not in use, a further design feature is provided: a spool is installed at the outer end of the inner cylinder; the warning tape is wound onto the spool; the spool is elastically connected to the inner cylinder via a spring for automatic winding of the warning tape.

[0014] The locking structure of the warning tape is as follows: a locking plate is provided at the outer end of the inner cylinder; the locking plate is provided with a first locking groove and a second locking groove; a locking rod is connected to the moving end of the warning tape; when the warning tape is rolled up, it locks with the first locking groove; when the warning tape is stretched, it locks with the second locking groove of the adjacent telescopic rod.

[0015] The beneficial effects of this utility model are: 1. The telescopic rod is hinged to the support column. When it rotates to be parallel to the support column, it is retracted. When it is opened to the horizontal, it is engaged with the adjacent telescopic rod by the warning tape, so that the telescopic rod and the warning tape form a ring-shaped warning area to prevent visitors from touching the exhibits. This not only makes the warning tape easy to assemble and disassemble, but also eliminates the storage space required by traditional warning lines; 2. The setting of the compression spring supports the telescopic rod, so that the telescopic rod remains in the extended state, thereby improving the stability of the connection structure of the warning tape.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] like Figure 1 As shown, this utility model discloses a product art design display device, which consists of a display stand 1, a support column 2 and a base 3 connected from top to bottom. The display stand 1 and the base 3 are arranged horizontally, and the support column 2 is arranged vertically.

[0026] At least three rotationally symmetrical telescopic rods 4 are hinged to the support column 2; a warning strip 6 connects the ends of the telescopic rods 4 to form a ring-shaped warning area. To increase the area of ​​the warning area, six telescopic rods 4 are used in this embodiment.

[0027] like Figure 5As shown, the telescopic rod 4 comprises an outer cylinder 41, several middle cylinders 42, and an inner cylinder 43 arranged sequentially from the outside to the inside. The number of middle cylinders 42 is determined according to the required length of the telescopic rod 4 after it extends; in this embodiment, the number of middle cylinders 42 is set to one. A hinge seat 10 is provided at the inner end of the outer cylinder 41, which is hinged to the support column 2.

[0028] The outer cylinder 41 has an inwardly protruding fixed limiting ring 411 at its outer end; the middle cylinder 42 has an outwardly protruding central locking ring 421 at its inner end and an inwardly protruding movable limiting ring 422 at its outer end; the inner cylinder 43 has an outwardly protruding inner locking ring 431 at its inner end. When the telescopic rod 4 extends, the central locking ring 421 engages with the fixed limiting ring 411, and the inner locking ring 431 engages with the movable limiting ring 422. If there is more than one middle cylinder 42, the central locking ring 421 of the inner middle cylinder 42 engages with the movable limiting ring 422 of the outer middle cylinder 42.

[0029] A baffle 8 is vertically installed on the inner wall of the inner cylinder 43. A compression spring 5 is installed inside the inner cylinder 43, with one end abutting against the bottom plate at the inner end of the outer cylinder 41 and the other end abutting against the baffle 8. When the compression spring 5 is in its free state, the telescopic rod 4 is in the extended state.

[0030] A warning tape 6 is installed at the opening / closing end of the inner cylinder 43. One end of the tape is fixed to the inner cylinder 43, while the other end floats, used to engage adjacent inner cylinders 43. The specific installation structure of the warning tape 6 is as follows: a freely rotatable roller 44 is installed inside the opening / closing end of the inner cylinder 43. One end of the warning tape 6 is fixed to the roller 44 and wound around it. A spring 9 is also installed on the roller 44, elastically connected to the inner cylinder 43, for automatic winding of the warning tape 6, thus facilitating its storage.

[0031] The inner cylinder 43 has a blocking snap plate 45 at its opening and closing end; the snap plate 45 has an elongated slot in the middle, the movable end of the warning tape 6 extends outward from the slot, and the movable end is fixedly connected to a snap rod 61.

[0032] like Figure 3 and Figure 4As shown, the outer surface of the snap-fit ​​plate 45 is provided with two symmetrically arranged rectangular protrusions 46. One end of each protrusion 46 is provided with a U-shaped first groove extending along the length of the protrusion 46. The openings of the two first grooves face each other and penetrate the opposite sides of the protrusions 46. The two first grooves form a first locking groove 451. When the warning tape 6 is not in operation, the snap-fit ​​rod 61 is engaged in the first locking groove 451, thereby preventing the warning tape 6 from retracting into the inner cylinder 43 when it is rolled up, making it difficult to pull out. The other end of the protrusion 46 is provided with a U-shaped second groove 4521. The second groove 4521 extends along the thickness of the protrusion 46, with one end penetrating the outer surface of the protrusion 46 parallel to the snap-fit ​​plate 45, and the other end abutting against the snap-fit ​​plate 45. A third groove 4522 extends vertically outward from the groove wall of the second groove 4521 away from the first groove. The opening ends of both the second groove 4521 and the third groove 4522 penetrate the opposite sides of the protrusion 46. The second groove 4521 and the third groove 4522 form the second locking groove 452. When the warning tape 6 needs to be pulled out to form a warning area, the locking rod 61 first locks into the second groove 4521 of the adjacent telescopic rod 4, and then locks into the third groove 4522, thereby completing the locking and fixing of the locking rod 61.

[0033] The support column 2 has a storage groove 21 on its side; the telescopic rod 4 is hinged to the upper part of the bottom of the storage groove 21. When the telescopic rod 4 rotates to a horizontal state, its upper side abuts against the upper wall of the storage groove 21, thereby achieving the rotation limit of the telescopic rod 4.

[0034] The length of the storage slot 21 is greater than or equal to the length of the telescopic rod 4 after it is retracted. With this design, the telescopic rod 4 will be blocked by the lower wall of the storage slot 21 after it is retracted, thus keeping the telescopic rod 4 stable in the retracted state and making it easy to store the telescopic rod 4.

[0035] The area of ​​the support column 2 with the storage groove 21 is provided with external threads, and a limit sleeve 7 is threadedly connected to it; such as Figure 1 As shown, when the telescopic rod 4 needs to open, first rotate the limiting sleeve 7 so that the limiting sleeve 7 disengages downward from the telescopic rod 4. When the telescopic rod 4 rotates to the horizontal position, rotate the limiting sleeve 7 in the opposite direction so that the limiting sleeve 7 moves upward and abuts against the telescopic rod 4. The telescopic rod 4 is then clamped between the limiting sleeve 7 and the upper wall of the storage groove 21, thus fixing the position of the telescopic rod 4 after it opens. Figure 2 As shown, when the telescopic rod 4 needs to be stored, first rotate the limiting sleeve 7 so that the limiting sleeve 7 moves downward and disengages from the storage groove 21. Then rotate and compress the telescopic rod 4 so that the telescopic rod 4 is engaged in the storage groove 21. Finally, rotate the limiting sleeve 7 in the opposite direction so that the limiting sleeve 7 rises and clamps the outside of the telescopic rod 4, so that the telescopic rod 4 is limited between the bottom of the storage groove 21 and the inner wall of the limiting sleeve 7, thereby keeping the telescopic rod 4 in a stable storage position.

[0036] In other embodiments, the telescopic rod 4 can be hinged to the lower end of the storage groove 21, and when the telescopic rod 4 is opened or closed, the limiting sleeve 7 moves upward first.

[0037] Compared with the prior art, the beneficial effects of this embodiment are: 1. The telescopic rod 4 is hinged to the support column 2. When it rotates to be parallel to the support column 2, it is retracted. When it is opened to the horizontal, it is engaged with the adjacent telescopic rod 4 by the warning tape 6, so that the telescopic rod 4 and the warning tape 6 form a ring-shaped warning area to prevent visitors from touching the exhibits. This not only makes the warning tape 6 easy to assemble and disassemble, but also eliminates the storage space required by the traditional warning line; 2. The setting of the compression spring 5 supports the telescopic rod 4, so that the telescopic rod 4 remains in the extended state, thereby improving the stability of the connection structure of the warning tape 6.

[0038] Because the telescopic rod 4 will quickly pop out under the action of the compression spring 5 when it is removed from the storage slot 21, which may easily cause injury to the human body, the following design is also made: Figure 6 As shown, the outer wall of the middle retaining ring 421 is fitted with a sealing ring 11, forming a sealed connection with the outer cylinder 41; the outer wall of the inner retaining ring 431 is fitted with a sealing ring 11, forming a sealed connection with the middle cylinder 42; the outer wall of the baffle 8 is welded to the inner wall of the inner cylinder 43. An air hole 81 is provided at the center of the baffle 8. This arrangement, with the baffle 8, inner cylinder 43, middle cylinder 42, and outer cylinder 41 forming a closed space, communicates with the outside only through the air hole 81. When the inner cylinder 43 extends outward, due to the small flow area of ​​the air hole 81, the air pressure in this space is difficult to quickly balance with the outside, thus creating a negative pressure in this space, which resists the extension of the inner cylinder 43 and reduces its extension speed. The extension speed of the inner cylinder 43 can also be changed by adjusting the size of the air hole 81.

[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
