Description

Technical Field

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

[0002] At present, there are many ways to install signboards in power plants, among which the hanging type is more common, and the hanging type is usually fixed by hanging with wire ropes. This method is suitable for situations where the signboard is light and needs to be hung for installation. First, it is necessary to install a hanging bracket at the installation location, and then pass the wire rope through the hanging hole of the signboard to hang the signboard on the hanging bracket. This method is flexible to install, and the position and height of the signboard can be adjusted as needed. However, the traditional hanging of signboards has the following defects:

[0003] It is not convenient to replace the signboard, the wire rope hanging operation is not convenient, and it cannot be adaptively installed for different scenarios. The wire rope has a single shape and a fixed length, and cannot be adaptively adjusted according to different installation scenarios. Most installation locations are high, and it is inconvenient to check which hook is suitable for the installation environment before replacing it. After the signboard is hung, it needs to be temporarily moved and it is not easy to disassemble. In addition, the ordinary hanging method also makes it easy for the signboard to have problems such as inflexible hanging angles and blocking the equipment. Utility Model Content

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.

[0032] Example 1

Spring 202c-6, wherein the fixed shell 202c-1 is socketed with the push rod 202b, and the fixed shell 202c-1 is fixedly connected to the replacement turntable 201b, the push block 202c-2 is fixedly connected to the push rod 202b, and the limit rocker 202c-5 is provided with a sliding pin 203d at one end on one side of the push block 202c-2, and the sliding pin 203d is adapted to the size of the first limit slide 202c-3 and the second limit slide 202c-4, and the limit rocker 202c-5 is hinged to the fixed shell 202c-1.

[0051] It should be noted that the first limiting slideway 202c-3 and the second limiting slideway 202c-4 are symmetrically distributed on the surface of the pushing block 202c-2.

[0052] Furthermore, the clamping assembly 203 includes a pushing rod 203a arranged on one side of the pushing block 202c-2, a swing link 203b arranged on both sides of the pushing rod 203a, a clamping claw 203c arranged on one side of the swing link 203b, a sliding pin 203d penetrating through one end of the swing link 203b, and a sliding groove 203e arranged on the outside of the sliding pin 203d, wherein the pushing rod 203a is fixedly connected to the pushing block 202c-2, the swing link 203b is connected to the pushing block 202c-2, the clamping claw 203c is hinged to the swing link 203b, the sliding pin 203d is slidably connected to the sliding groove 203e, and the sliding pin 203d is hinged to the swing link 203b.

[0053] It should be noted that the pushing rod 203a is arranged on the inner side of the return spring 202c-6, and a strong magnet is provided at one end of the pushing rod 203a connected to the hook, which can adsorb the hook so that when the hook is connected to the identification plate, the identification plate can be hung at the same time.

[0054] When in use, the staff rotates the manual wheel 102c in the opposite direction according to the direction of the hook position required, and drives the active rotating rod 102b to rotate synchronously in the same direction through the manual wheel 102c, and the active rotating rod 102b drives the synchronous rotating wheel to rotate synchronously in the same direction, and the synchronous rotating wheel drives the intermittent rotating rod 103a to rotate synchronously in the same direction. The intermittent rotating rod 103a enters the through groove provided in the intermittent wheel every time the synchronous rotating wheel rotates one circle, driving the intermittent wheel to rotate 1 / 4 circle, and the intermittent wheel drives the replacement turntable 201b to rotate synchronously in the same direction, so that the required hook and fixed pushing member 202c are rotated to the installation position at the same time. When the hook and fixed pushing member 202c move to the installation position, the inclined surface provided on the pushing rod 202b contacts the inclined surface provided on the pushing fixed disk 202a, and the fixed disk 202a is pushed to squeeze the pushing rod 202b, so that the pushing rod 202b is moved to When the push rod 202b is pushed to the bottom, the limit swing rod 202c-5 reaches the highest point of the second limit slide 202c-4, and the reset spring 202c-6 is compressed to the shortest point, and the push block 202c-2 pushes the swing link 203b outward, so that the swing link 203b moves outward along the sliding groove 203e through the sliding pin 203d, driving the clamping claw 203c to open to both sides. At the same time, the pushing rod 203a follows the pushing block 202c-2 to move outward, pushes the hook, and makes the hidden buckle of the hook and the hidden buckle of the sign engage with each other. At this time, the sign can be directly hung at the position where the replacement mechanism is located, or it can be removed together with the hook and hung at other required positions. When the hook needs to be removed, the manual wheel 102c is further rotated to drive the replacement turntable 201b to continue to rotate through the intermittent wheel. When the pushing rod 202b leaves the pushing fixed disk 202a, the pressure is released, the pressure of the reset spring 202c-6 disappears, and the pushing block 202c-2 is pushed inward. The pushing block 202c-2 moves to the innermost side, and the limiting swing rod 202c-5 continues to slide to the bottom along the second limiting slide 202c-4. At the same time, the pushing block 202c-2 drives the swing link 203b to move inward along the sliding groove 203e, and the swing link 203b drives the clamping claw 203c to retract inward, and the clamping hook moves inward synchronously, so that the hook is detached from the identification plate, and the disassembly is completed.

[0055] In summary, the beneficial effect of a convenient replacement mechanism is that the power component 102 is manually rotated, and the intermittent component 103 ensures that the required hook stays in the installation position, so as to avoid the rotating component 201 rotating beyond the installation position when the sign is installed or the hook is removed. By cooperating with the pushing component 202 and the rotating component 201, the hook is pushed out for installation or pulled back for removal while moving to the installation position, so that the hook can be conveniently replaced when the type of sign is changed, and the mechanism can store multiple hooks at the same time, so as to avoid the loss of the hook when the sign is installed, and it is convenient to temporarily change the hanging position of the sign.

[0060] Furthermore, the adjustment component 301 includes a connection fixing seat 301a arranged at the bottom of the installation component 101, a ratchet 301b arranged at the lower side of the connection fixing seat 301a, a pawl 301c arranged at one side of the ratchet 301b, and an adjustment shell 301d arranged outside the ratchet 301b.

[0061] Furthermore, the fixing assembly 302 includes a mounting suction cup 302a disposed on one side of the adjusting housing 301d, a silicone pad 302b disposed on the inner side of the mounting suction cup 302a, and a control panel 302c disposed on one side of the mounting suction cup 302a.

[0063] When in use, the staff adjusts the angle by rotating the adjustment shell 301d. At the same time, the ratchet 301b rotates synchronously, and the pawl 301c limits the ratchet 301b so that the pawl 301c does not rotate in the opposite direction. When the angle of the connecting and fixing seat 301a is adjusted to be parallel to the installation plane, the connecting and fixing seat 301a is pressed to the installation plane to make the silicone pad 302b fit the installation plane. Further, the staff presses the control panel 302c, and the control panel 302c drives the silicone pad 302b to move toward the inside of the installation suction cup 302a, and at the same time applies pressure to the installation plane, so that the silicone pad 302b fits the installation suction cup 302a, and the air inside is sucked out to form a vacuum environment, so that the installation suction cup 302a is sucked on the installation plane to fix the entire mechanism.

[0064] In summary, the beneficial effect of a fixing device is that the angle between the installer and the connecting fixing seat 301a can be adjusted by the cooperation of the ratchet 301b and the pawl 301c, and the overall structure can be fixed on the installation plane by the cooperation of the installation suction cup 302a and the silicone pad 302b, so that the installation of the signboard can adapt to various angle installation environments, while also ensuring that the damage to the installation plane is reduced during the installation process.
