Technical Field

[0001] The utility model relates to the technical field of identification plate installation, in particular to an identification plate fixing mechanism and an installation frame. Background Art

[0002] A sign is a visual tool used to indicate direction, location or operation method, warn of danger, provide information, and guide people's behavior. Signs usually use text, graphics, colors, shapes, etc., and are used in many fields such as road traffic, public places, buildings, product descriptions, etc. Signs may also refer to billboards with advertising functions. Signs play an important role in people's lives. They not only provide necessary guidance and warnings, but also facilitate use and maintenance.

[0003] At present, when installing signboards outdoors, one signboard is usually equipped with one mounting frame, and the mounting frame is also welded in advance according to the size of the signboard for adaptation, so it cannot be used for signboards of different sizes, resulting in single functionality and poor versatility. Utility Model Content

[0004] In view of the technical problem that the identification plates of different sizes cannot be installed in the above-mentioned or existing technologies, the present utility model is proposed.

[0005] The utility model aims to provide a identification plate fixing mechanism.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: including:

[0007] The main body component includes a positioning frame, a movable slider slidably connected to the positioning frame, and a threaded cylinder arranged at one end of the movable slider;

[0008] The force unloading component includes a wind feedback component and a wind load buffer component. There are two groups of wind feedback components and wind load buffer components. The two groups of wind feedback components and wind load buffer components are arranged in a mirror-symmetrical manner about the transverse center line of the positioning frame. The two groups of wind feedback components and wind load buffer components are connected to the positioning frame through a threaded tube. The two groups of wind feedback components and wind load buffer components can fix the signboard.

[0009] As a preferred solution of the identification plate fixing mechanism of the utility model, wherein: the inner side of the threaded barrel is threadedly connected with a bidirectional threaded rod, the bottom end of the bidirectional threaded rod is fixedly installed with an adjustment disk, the outer side of the adjustment disk is provided with a limiting ring, and the limiting ring is fixedly installed on one side of the positioning frame;

[0010] The bidirectional threaded rod will move two sets of wind feedback components and wind load buffer components when rotating. The wind feedback components and wind load buffer components are threadedly connected to the bidirectional threaded rod through a threaded tube to strengthen the fixation of the identification plate and adapt to identification plates of different sizes.

[0011] As a preferred solution of the identification plate fixing mechanism of the utility model, wherein: the wind force feedback member includes a fixed edge strip, a circular ring arranged on one side of the fixed edge strip, and an arc-shaped protrusion arranged on the outer side of the circular ring, and a positioning shaft hinged to the inner side of the circular ring;

[0012] The wind load buffer comprises a cylinder, which is fixedly mounted on the outer side of the threaded cylinder, and also comprises a through groove opened on the outer side of the cylinder;

[0013] The positioning shaft is fixedly installed on the outside of the cylinder, the arc-shaped protrusions are arranged in the through grooves, the arc-shaped protrusions are symmetrically distributed on the outside of the ring, and the wind force feedback component and the wind load buffer component are connected to the fixed edge strip through the positioning shaft.

[0014] As a preferred solution of the identification plate fixing mechanism of the utility model, the wind load buffer also includes a retaining frame, a rotating wheel rotatably connected to the retaining frame, the retaining frame is slidably connected to the inner side of the cylinder, and the rotating wheel is arranged in a close fit with the arc-shaped protrusion.

[0015] As a preferred solution of the identification plate fixing mechanism of the utility model, a shock absorbing spring is fixedly installed at the bottom of the retaining frame, and one end of the shock absorbing spring is in conflict with the cylinder.

[0016] As a preferred solution of the identification plate fixing mechanism of the utility model, a damper is fixedly installed at the bottom of the retaining frame, the shock-absorbing spring is arranged on the outside of the damper, and when the damper is in the retracted state, the rotating wheel is always in contact with the arc-shaped protrusion to prevent the arc-shaped protrusion from flipping over and out of position.

[0017] The beneficial effects of the sign fixing mechanism of the utility model are as follows: the sign is placed on the wind feedback member, and then the adjusting disk is rotated to make the threaded cylinder slide along the outer side of the bidirectional threaded rod, thereby driving the two groups of wind feedback members and the wind load buffer member to gather and clamp the sign, and then fix the sign. When the outdoor wind is too strong, the wind blows to the surface of the sign, which will cause the sign to deflect. When the sign deflects, it will drive the fixed edge strip to deflect. When the circular ring deflects, the arc-shaped protrusion contacts the positioning shaft, which will push the retaining frame to retract and squeeze the shock-absorbing spring. At the same time, the damper is used to consume wind force to achieve the effect of shock absorption and buffering to prevent damage to the sign. When the wind disappears, the shock-absorbing spring rebounds to drive the damper to extend, and at the same time pushes the retaining frame to reset. At this time, the rotating wheel will push the arc-shaped protrusion to deflect and make the sign return to the normal position, thereby reducing the direct contact area with the wind direction, effectively unloading part of the wind force, and preventing the sign from being deformed or falling off due to excessive wind pressure.

[0018] In actual use, there is still the problem that the installation height of the signboard is not convenient enough.

[0019] In order to solve the above technical problems, the utility model also provides the following technical solutions: a mounting frame; including the above-mentioned identification plate fixing mechanism; and,

[0032] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0035] Example 1

[0036] Reference Figure 1 , is the first embodiment of the utility model, which provides a sign fixing mechanism, including:

[0037] The main body component 100 includes a positioning frame 101, a movable slider 102 slidably connected to the positioning frame 101, and a threaded cylinder 103 provided at one end of the movable slider 102. The movable slider 102 slides in the positioning frame 101, and the positioning frame 101 limits the movable slider 102 so that the movable slider 102 can only slide up and down, so that the distance between the two movable sliders 102 can be adjusted to adapt to identification plates of different sizes;

[0038] The force unloading component 200 includes a wind feedback component 201 and a wind load buffer component 202. There are two groups of wind feedback components 201 and wind load buffer components 202. The two groups of wind feedback components 201 and wind load buffer components 202 are arranged in a mirror-symmetrical manner about the transverse center line of the positioning frame 101. The two groups of wind feedback components 201 and wind load buffer components 202 are connected to the positioning frame 101 through a threaded tube 103. The two groups of wind feedback components 201 and wind load buffer components 202 can fix the signboard. When the two groups of wind feedback components 201 and wind load buffer components 202 slide together, not only can the spacing be adjusted according to the size of the signboard, but also a certain clamping force is exerted on the signboard, thereby fixing the signboard.

[0039] Furthermore, the inner side of the threaded barrel 103 is threadedly connected with a bidirectional threaded rod 104, and an adjusting disk 105 is fixedly installed at the bottom end of the bidirectional threaded rod 104. A limiting ring 106 is provided on the outer side of the adjusting disk 105, and the limiting ring 106 is fixedly installed on one side of the positioning frame 101. The limiting ring 106 is used to limit the bidirectional threaded rod 104 so that the bidirectional threaded rod 104 will not disengage when rotating. By using the bidirectional thread setting of the bidirectional threaded rod 104, the bidirectional threaded rod 104 will drive the threaded barrel 103 to move in the opposite direction or relatively when rotating forward or reverse, so as to adjust the spacing according to the signboards of different sizes.

[0040] When the bidirectional threaded rod 104 is in a rotating state, the two sets of wind feedback components 201 and wind load buffer components 202 will move. The wind feedback components 201 and the wind load buffer components 202 are threadedly connected to the bidirectional threaded rod 104 through the threaded tube 103 to strengthen the fixation of the identification plate, and adapt to identification plates of different sizes. The pre-tightening force generated by the threaded engagement of the threaded tube 103 and the bidirectional threaded rod 104 is used to strengthen the fixation of the identification plate, thereby preventing the identification plate from falling off.

[0041] Usage process: place the identification plate on the wind feedback member 201, then rotate the adjustment disk 105 to make the threaded tube 103 slide along the outer side of the bidirectional threaded rod 104, thereby driving the two sets of wind feedback members 201 and the wind load buffer member 202 to gather and clamp the identification plate, thereby fixing the identification plate.

[0042] Example 2

[0043] Reference Figure 2, which is the second embodiment of the utility model, this embodiment further provides a wind feedback member 201, including a fixed side strip 201a, a circular ring 201b arranged on one side of the fixed side strip 201a, and an arc-shaped protrusion 201c arranged on the outer side of the circular ring 201b, and a positioning shaft 201d hinged on the inner side of the circular ring 201b. The fixed side strip 201a is L-shaped, so that it can support the sign. When the outdoor wind is too strong, the wind blows to the surface of the sign, which will cause the sign to deflect, thereby reducing the direct contact area with the wind direction, thereby effectively unloading part of the wind force and preventing the sign from being deformed or falling off due to excessive wind pressure.

[0044] The wind load buffer 202 includes a cylinder 202a, which is fixedly mounted on the outer side of the threaded cylinder 103, and also includes a through slot 202b provided on the outer side of the cylinder 202a. The through slot 202b can provide a certain activity space for the arc-shaped protrusion 201c when the fixed edge strip 201a drives the arc-shaped protrusion 201c to deflect.

[0045] The positioning shaft 201d is fixedly installed on the outside of the cylinder 202a, the arc-shaped protrusion 201c is arranged in the through groove 202b, and the arc-shaped protrusion 201c is symmetrically distributed on the outside of the ring 201b. The wind feedback member 201 and the wind load buffer member 202 are connected to the fixed edge strip 201a through the positioning shaft 201d, and are fixed to the fixed edge strip 201a through the positioning shaft 201d, so that the fixed edge strip 201a and the ring 201b can rotate freely within a certain range, so that the sign can achieve a certain angle of deflection, thereby removing the wind force;

[0046] Furthermore, the wind load buffer 202 also includes a retaining frame 202c, a rotating wheel 202d rotatably connected to the retaining frame 202c, the retaining frame 202c is slidably connected to the inner side of the cylinder 202a, the rotating wheel 202d is arranged in a close fit with the arc-shaped protrusion 201c, a shock-absorbing spring 202e is fixedly installed at the bottom of the retaining frame 202c, one end of the shock-absorbing spring 202e is in conflict with the cylinder 202a, and a damper 202f is fixedly installed at the bottom of the retaining frame 202c, and the shock-absorbing spring 202e is arranged on the outer side of the damper 202f. When the damper 202f is in the retracted state, the rotating wheel 202d is always in a close fit with the arc-shaped protrusion 201c to prevent the arc-shaped protrusion 201c from flipping over and offside. When the ring 201b is deflected, the arc-shaped protrusion 201c contacts the positioning shaft 201d, which will push the retaining frame 202c to retract and squeeze the shock-absorbing spring 202e. At the same time, the damper 202f is used to consume wind force to achieve the effect of shock absorption and buffering. After the retaining frame 202c is retracted to the maximum distance, the rotating wheel 202d and the arc-shaped protrusion 201c remain in contact, limiting the arc-shaped protrusion 201c to prevent the arc-shaped protrusion 201c from deflecting too much and separating from the cylinder 202a. When the wind force disappears, the shock-absorbing spring 202e rebounds to drive the damper 202f to extend, and at the same time push the retaining frame 202c to reset. At this time, the rotating wheel 202d will push the arc-shaped protrusion 201c to deflect and make the sign return to the normal state.

[0047] Usage process: When the outdoor wind is too strong, the wind blows to the surface of the sign, causing the sign to deflect. When the sign deflects, it will drive the fixed edge strip 201a to deflect. When the ring 201b deflects, the arc-shaped protrusion 201c contacts the positioning shaft 201d, which will push the retaining frame 202c to retract and squeeze the shock-absorbing spring 202e. At the same time, the damper 202f is used to consume wind power to achieve the effect of shock absorption and buffering to prevent damage to the sign. After the retaining frame 202c retracts to the maximum distance, the rotating wheel 202d and the arc-shaped protrusion 201c maintains a fitted state and limits the arc-shaped protrusion 201c to prevent the arc-shaped protrusion 201c from deflecting too much and separating from the cylinder 202a. When the wind disappears, the shock-absorbing spring 202e rebounds to drive the damper 202f to extend and push the retaining frame 202c to reset. At this time, the rotating wheel 202d will push the arc-shaped protrusion 201c to deflect and make the sign return to the normal state, thereby reducing the direct contact area with the wind direction, effectively unloading part of the wind force, and preventing the sign from being deformed or falling off due to excessive wind pressure.

When the locking component 303 is connected to the driving component 302, the main body component 100 is positioned on the support tube 301. The driving component 302 controls the lifting of the main body component 100. The locking component 303 is used to fix the driving component 302, so that the main body component 100 is fixed at a height to prevent the main body component 100 from moving.

The connecting rope 302b is arranged on the second rotating cylinder 302d, and the second rotating cylinder 302d provides assistance for the connecting rope 302b. To reduce resistance and alleviate wear, one end of the connecting rope 302b is fixedly connected to the positioning frame 101, and the positioning frame 101 and the support tube 301 are arranged in a sliding connection. The first rotating drum 302a is driven to rotate by turning the crank 302c. When the first rotating drum 302a reels in the connecting rope 302b, the positioning frame 101 will be pulled up, thereby raising the signboard. When the first rotating drum 302a reverses, the connecting rope 302b will be released.

[0054] The round frame 303a is fixedly installed on the outside of the support tube 301, and gaps are provided between the plurality of clamping plates 303b. The T-shaped locking rod 303c is slidably connected to the round frame 303a. The positioning frame 101 is inserted into the gaps between the plurality of clamping plates 303b and fixed via the T-shaped locking rod 303c.

[0055] Usage process: The first rotating drum 302a is driven to rotate by turning the crank 302c. When the first rotating drum 302a reels in the connecting rope 302b, the positioning frame 101 will be pulled up, thereby raising the identification plate. When the first rotating drum 302a reverses, the connecting rope 302b will be released. After the connecting rope 302b is stretched, the identification plate will be lowered, thereby adjusting the height of the identification plate. Then, the T-shaped locking rod 303c is inserted into the gap between the multiple clamping plates 303b to prevent the first rotating drum 302a from rotating, thereby fixing the position of the identification plate.
