Description

Technical Field

[0001] The utility model relates to the technical field of identification plates, in particular to an adjustable mechanism of a vertical identification plate. Background Art

[0002] In gardens, there are a large number of trees, and each tree needs to be maintained according to its specific growth conditions. Information data from multiple maintenance needs to be recorded for use in tree growth research. In order to facilitate timely understanding of the maintenance conditions of the seedlings, such as nurturing, pruning, and fertilizing, identification plates are generally set on the trunks of the seedlings.

[0003] Patent No.: CN220984068U, discloses an information sign for forest trees. By setting a first sealed bottom plate, a back plate, a first magnetic ring, an information leaflet and a marker pen, after the seedling maintenance is completed, the first sealed bottom plate can be pulled downward to disconnect it from the first magnetic ring at the bottom of the signboard shell, and at the same time drive the sealing block and the back plate to be pulled out of the signboard shell. After being pulled out, the second sealed bottom plate can be pulled downward to disconnect it from the second magnetic ring at the bottom of the storage box, and at the same time drive the marker pen to be pulled out of the storage box. The pulled out marker pen can record data and maintenance information on the information leaflet on the back plate, so that the information of the seedling can be timely understood during the next maintenance.

[0004] However, in the process of implementing this plan, in order to avoid the surrounding water from spraying onto the sign during the process of watering the garden, thereby affecting the pollution of the information sign and the subsequent recording and modification of the sign information, the recorders habitually hang the sign high. However, when tourists or some other recorders want to check or change the information on the sign, due to the different heights of people, they often need to use other external equipment to take it down, check or change it. The height of the sign cannot be changed independently according to the height of the tourists or recorders, which is inconvenient to use. It is not convenient for tourists to understand the trees, and it is not convenient for other recorders to maintain the trees. Therefore, an adjustable mechanism for a vertical sign is proposed.

[0023] See also Figure 1-4 The utility model provides a technical solution: an adjustable mechanism of a vertical sign, including a support rod 1, an internal sliding tube of the support rod 1 is connected with an adjusting rod 2, a sign housing 9 is arranged on the top of the adjusting rod 2, a tree information sign is placed inside the sign housing 9, two arc springs 3 are fixedly connected to the surface of the sign housing 9, the opposite ends of the two arc springs 3 are respectively fixedly connected with a fixing plate 4 and a connecting plate 5, a bolt 6 is rotatably connected to the side of the fixing plate 4 close to the connecting plate 5, and the surface of the bolt 6 is threadedly connected to the internal thread of the connecting plate 5, so that the elastic force of the arc spring 3 can be used to restrain the device on trees of different sizes, thereby improving the applicability of the device.

[0024] The bottom of the support rod 1 is also provided with an arc spring 3, a fixing plate 4, a connecting plate 5, and a bolt 6, which are used to tie the tree again, thereby improving the connection strength between the device and the tree.

[0025] Furthermore, the support rod 1 is internally slidably connected with an insertion rod 14 that passes through the surface of the support rod 1, the surface of the insertion rod 14 is fixedly connected with a U-shaped frame 13, the inner wall of the U-shaped frame 13 is fixedly connected with a reset spring 15, and the reset spring 15 is fixedly connected to the surface of the support rod 1 away from the U-shaped frame 13, so as to reset the U-shaped frame 13 and the insertion rod 14.

[0026] The surface of the adjustment rod 2 is provided with slots 7 arranged at equal intervals, and the slots 7 and the insertion rod 14 are adapted to each other. The overall height of the device can be adjusted by inserting the insertion rod 14 into the slots 7 at different positions, thereby making it convenient for recorders of different heights to change the identification card information in the identification card housing 9, thereby improving the use effect of the device.

[0027] Furthermore, the internal rotation of the adjusting rod 2 is connected to a rotating shaft 17, and the surface of the rotating shaft 17 is fixedly connected to a gear 16. The internal sliding connection of the adjusting rod 2 is provided with two racks 8 that penetrate the surface of the adjusting rod 2. The gear 16 is located between the two racks 8. The surfaces of the two racks 8 are meshed with the surfaces of the gear 16. The opposite ends of the two racks 8 are fixedly connected to a connecting rod 10 that is arranged obliquely. The surfaces of the two arc springs 3 on the identification plate housing 9 are fixedly sleeved with fixing sleeves 11. The ends of the two connecting rods 10 away from the two racks 8 are fixedly connected to the surfaces of the two fixing sleeves 11 respectively, and then the staff can drive the two racks 8 to rotate by driving the gear 16. The two fixing sleeves 11 are moved back and forth, thereby pulling the two fixing sleeves 11 through the connecting rod 10, so that the two fixing sleeves 11 move back and forth, and then the two arc springs 3 are stretched, so that the arc springs 3 are no longer in close contact with the surface of the tree, and then the staff can lower the sign housing 9 by operating other steps, so that the staff does not need to untie the connection between the two upper arc springs 3 to lower the sign housing 9, so that the sign housing 9 can adjust the height independently according to the user's requirements, thereby facilitating recorders of different heights to change and view the tree sign information, improving the convenience of using the device and improving the practicality of the device.

[0029] Specifically, when it is necessary to lower the sign housing 9 and change the information on the sign, the recorder can rotate the screw 12, through the transmission of the pulley 18 and the belt 19, drive the gear 16 to rotate, thereby driving the two racks 8 to move away from each other, thereby driving the two connecting rods 10 to move away from each other, and then pulling the two arc springs 3 to move away from each other, so that the upper arc spring 3 is no longer in close contact with the tree. At this time, the recorder can pull the U-shaped frame 13 so that the insertion rod 14 is no longer stuck in the slot 7, so that the adjustment rod 2 can be smoothly lowered in the support rod 1, and then the height of the adjustment rod 2 can be adjusted, thereby facilitating recorders at different heights to change or view the sign in the sign housing 9.

[0030] Working principle: When it is necessary to lower the sign housing 9 and change the information on the sign, the recorder can rotate the screw 12, through the transmission of the pulley 18 and the belt 19, drive the gear 16 to rotate, and then drive the two racks 8 to move away from each other, thereby driving the two connecting rods 10 to move away from each other, and then pull the two arc springs 3 to move away from each other, so that the upper arc spring 3 is no longer in close contact with the tree. At this time, the recorder can pull the U-shaped frame 13 so that the insertion rod 14 is no longer stuck in the slot 7, so that the adjustment rod 2 can be smoothly lowered in the support rod 1, and then the height of the adjustment rod 2 can be adjusted.
