Description

Technical Field

[0001] This utility model belongs to the technical field of location identification equipment, and in particular relates to a novel location identifier. Background Technology

[0002] When installing a fresh air system or air conditioner, the exact location needs to be marked in advance so that the installers know the exact location during installation. The traditional marking method involves workers climbing up using an A-frame ladder and spraying the markings with a spray gun, which is quite dangerous.

[0003] To address this issue, the applicant proposed a position marker in utility model patent application number 202321955909.3. This marker mainly comprises a rod, a printed element, and a hinge. The hinge is fixed to the rod and rotates with the printed element, giving the printed element two degrees of freedom of movement. Workers can perform the marking operation by holding the rod and adjusting the orientation of the printed surface, effectively improving operational safety. However, in actual use, it has been found to have at least the following drawbacks: Firstly, the overall structure is complex, and workers need to adjust two degrees of freedom of movement simultaneously to change the orientation of the printing surface, which is cumbersome and affects work efficiency.

[0004] Secondly, the structure has poor stability. The hinges are prone to loosening due to the large pressure they need to withstand, which can lead to unclear text / graphic markings and affect the user experience. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit this application. The connection relationships shown in the accompanying drawings are only for clear description and do not limit the connection method.

[0025] See appendix Figure 1 -Appendix Figure 9 A novel position marker includes a rod 1, a printed element 2, a fixing frame 3, and a locking element 4; the printed element 2 has multiple printed surfaces 20; the fixing frame 3 is mounted on the rod 1 and rotatably connected to the printed element 2, and the printed element 2 is rotated to adjust the orientation of each printed surface 20 one by one; the locking element 4 is mounted on the fixing frame 3 and is set corresponding to the printed element 2 to lock or release the printed element 2.

[0026] Specifically, in use, first control the locking part 4 to release the printed part 2, then rotate the printed part 2 to switch the required printing surface 20. After the orientation of the required printing surface 20 is adjusted, lock the printed part 2 with the locking part 4 so that the printing surface 20 remains stable and maintains its current orientation. Then, the worker holds the rod 1 and moves the printed part 2 close to the area to be marked until the printing surface 20 is in parallel contact with the surface of the area to be marked to complete the marking operation. When it is necessary to change the marking content, first control the locking part 4 to release the printed part 2, then rotate the printed part 2 to switch the required printing surface 20, and then repeat the above operation.

[0027] The area to be marked is generally the ceiling surface, so the switched printing surface 20 is usually set upwards to ensure that the printing surface 20 can contact the ceiling surface in parallel. The area to be marked can also be a wall surface. In this case, the switched printing surface 20 faces left and right to ensure that the printing surface 20 can contact the wall surface in parallel. On the other hand, according to the content to be marked, corresponding text and patterns can be set on the printing surface 20. Since there are many actual usage methods and many contents to be marked, this utility model does not impose any restrictions.

[0028] In summary, this utility model constitutes a position marker by connecting the rod body 1 and the printed part 2 through the fixing frame 3. The overall structure is simple, which can effectively reduce the cost. Moreover, the fixing frame 3 is directly rotatably connected to the printed part 2, so only one degree of freedom of movement needs to be adjusted to change the orientation of the printed surface 20, making the operation relatively simple and improving work efficiency. At the same time, the structure that restricts the degree of freedom of movement by pre-tightening the printed part 2 through the locking part 4 has high stability, which can effectively reduce the possibility of the printed part 2 becoming loose, ensuring that the text / patterns can be clearly marked, and improving the user experience.

[0029] See appendix Figure 4 -Appendix Figure 10The fixing frame 3 includes a connecting arm 30, a first support arm 31, and a second support arm 32. The connecting arm 30 is mounted on the rod body 1. The first support arm 31 and the second support arm 32 are respectively fixed to both ends of the connecting arm 30 so that the fixing frame 3 is U-shaped. The printed part 2 is disposed between the first support arm 31 and the second support arm 32, and the printed part 2 is rotatably connected to the first support arm 31 and / or the second support arm 32. The locking part 4 is mounted on the first support arm 31 or the second support arm 32 and is disposed corresponding to the printed part 2 to lock or release the printed part 2.

[0030] Specifically, the U-shaped design of the fixing frame 3, which surrounds the printed part 2, not only makes the center of gravity of the printed part 2 and the fixing frame 3 consistent to reduce the vibration of the printed part 2, but also prevents the two ends of the printed part 2 from being exposed and accidentally touching the workers.

[0031] Since there are various ways to connect the printed part 2 and the locking part 4 to the first arm 31 and the second arm 32 of the fixing frame 3, this utility model does not limit this. The following are three examples of connection methods: First, the printed part 2 is rotatably connected only to the first support arm 31, and the locking part 4 is set on the first support arm 31. The second support arm 32 serves to enclose the two ends of the printed part 2 and the balance fixing frame 3. Conversely, if the printed part 2 is rotatably connected only to the second support arm 32, and the locking part 4 is set on the second support arm 32, then the first support arm 31 serves to enclose the two ends of the printed part 2 and the balance fixing frame 3.

[0032] Second, the printed part 2 is rotatably connected only to the first support arm 31, and the locking part 4 is set on the second support arm 32. The second support arm 32 can also support the printed part 2 and improve its load-bearing capacity. Conversely, if the printed part 2 is rotatably connected only to the second support arm 32, and the locking part 4 is set on the first support arm 31, then the first support arm 31 can also support the printed part 2 and improve its load-bearing capacity.

[0033] Third, the printed part 2 is rotatably connected to the first arm 31 and the second arm 32, and the locking part 4 is set on the first arm 31 / second arm 32. In the marking process, the force on the printed part 2 can be transmitted to the connecting arm 30 and the rod 1 through the first arm 31 and the second arm 32, so as to ensure that the force on both ends of the printed part 2 is more uniform and improve the structural stability, thereby reducing the possibility of the printed part 2 shaking.

[0034] It should be noted that in practical use, the third connection method offers higher structural stability. Therefore, if manufacturing costs are not a concern, the third connection method should be preferred. For ease of understanding, this utility model provides a schematic diagram illustrating the third connection method. Please refer to the appendix for details. Figure 4 -Appendix Figure 10 .

[0035] See appendix Figure 5 -Appendix Figure 10 The present invention also includes a fastening bolt 5, which is disposed on the connecting arm 30 and threadedly connected to the rod body 1 to install the connecting arm 30 on the rod body 1. This design facilitates the disassembly and assembly between the fixing frame 3 and the rod body 1, allowing the fixing parts and the rod body 1 to be manufactured separately, thereby improving the convenience of production and use. The fastening bolt 5 is welded to the connecting arm 30 or directly integrally formed.

[0036] See appendix Figure 1 -Appendix Figure 5 The connecting arm 30 is provided with a through hole 300, which has an upper hole position 301 and a lower hole position 302. The head end of the fastening bolt 5 is placed in the upper hole position 301, and the tail end of the fastening bolt 5 passes through the lower hole position 302 and is threadedly connected to the rod body 1. The cross-section of the head end of the fastening bolt 5 and the upper hole position 301 are both polygonal and are adapted to snap-fit ​​to restrict the rotation of the fastening bolt 5.

[0037] Specifically, during assembly, the fastening bolt 5 is first inserted into the through hole 300, with the tail end of the fastening bolt 5 passing through the lower hole 302 and the head end of the fastening bolt 5 engaging with the upper hole 301, thereby restricting the rotation of the fastening bolt 5; then, the rod body 1 is threadedly connected to the tail end of the fastening bolt 5, thus completing the assembly between the fixing frame 3 and the rod body 1; therefore, the above structural design can not only improve the ease of assembly, but also avoid removing the fastening bolt 5 from the fixing frame 3, preventing the fastening bolt 5 from being exposed and scratching the user. At the same time, after the fastening bolt 5 is installed, it can also be hidden to improve the aesthetics.

[0038] See appendix Figure 4 -Appendix Figure 12 The specific rotational mounting structure between the printed part 2 and the first arm 31 and / or the second arm 32 of the fixing frame 3 varies, and this utility model does not limit it. For ease of understanding, two embodiments are described here: Example 1 As attached Figure 4 -Appendix Figure 6 As shown, the printed part 2 is provided with a rotating shaft 211 and a threaded shaft 212 at both ends. The tail end of the rotating shaft 211 rotatably passes through the first support arm 31 and is fixedly connected to a screw block 6. The tail end of the threaded shaft 212 rotatably passes through the second support arm 32. The locking part 4 includes a screw sleeve 41 that is threadedly connected to the tail end of the threaded shaft 212. Tightening the screw sleeve 41 can abut against the second support arm 32 and lock the printed part 2.

[0039] Specifically, during assembly, it must be ensured that the first arm 31 or the second arm 32 is not installed on the connecting arm 30. If the second arm 32 is not installed on the connecting arm 30, the manufacturer can first rotatably pass the rotating shaft 211 through the first arm 31, then rotatably pass the threaded shaft 212 through the second arm 32, and finally fix the second arm 32 to the connecting arm 30 by welding, snap-fitting, or other methods to complete the installation of the printed part 2. After the printed part 2 is installed, the threaded sleeve 41 is threadedly connected to the tail end of the threaded shaft 212.

[0040] Example 2 As attached Figure 7 -Appendix Figure 12 As shown, the printed part 2 has a slot 213 extending from both ends to connect to the outside. The fixing frame 3 also includes a rotating rod 33. The first end of the rotating rod 33 is provided with a rotating block 6. The tail end of the rotating rod 33 can pass through the first support arm 31, the slot 213 and the second support arm 32 in sequence. The rotating rod 33 is rotatably connected to the first support arm 31 and / or the second support arm 32. The cross-section of the slot 213 and the rotating rod 33 are both polygonal and adapted to snap together to restrict the rotation of the printed part 2 relative to the rotating rod 33. The locking part 4 adopts a screw sleeve 41 that is threadedly connected to the tail end of the rotating rod 33. Tightening the screw sleeve 41 can abut against the second support arm 32 to lock the printed part 2.

[0041] Specifically, during assembly, the printed part 2 is first placed between the first arm 31 and the second arm 32. Then, the tail end of the rotating rod 33 can pass through the first arm 31, the slot 213 and the second arm 32 in sequence until the rotating block 6 contacts the first arm 31. Then, the screw sleeve 41 is threadedly connected to the tail end of the threaded shaft 212, so that the installation of the printed part 2 and the locking part 4 can be completed simultaneously.

[0042] In both Embodiment 1 and Embodiment 2, when using the printed part 2, turning the screw sleeve 41 to disengage from the second support arm 32 can release the restriction on the printed part 2. Turning the screw block 6 can drive the printed part 2 to rotate and switch the printing surface 20. After switching to the desired printing surface 20, turning the screw sleeve 41 to abut against the second support arm 32 can lock the printed part 2. The operation is very simple.

[0043] It should be noted that the rotating mounting structure in Embodiment 1 has a relatively low manufacturing cost, but its assembly is more complicated and it is not conducive to disassembly later; the rotating mounting structure in Embodiment 2 is very convenient to assemble and disassemble, but its manufacturing cost is relatively high. Therefore, in the actual production process, the manufacturer can choose according to the needs. Of course, the printing frame can also use other structures to rotatably connect with the first arm 31 and the second arm 32, and use them in conjunction with the locking part 4. Since there are many types of related structures, they will not be listed one by one in this utility model.

[0044] On the other hand, in Embodiment 1, as shown in the appendix Figure 5 -Appendix Figure 6As shown, both the rotating shaft 211 and the threaded shaft 212 are fitted with washers 8. One washer 8 abuts against the first support arm 31 and the printed part 2, and the other washer 8 abuts against the second support arm 32 and the printed part 2. In embodiment two, as shown in the attached figure... Figure 9 Appendix Figure 10 and attached Figure 12 As shown, both ends of the rotating rod 33 are fitted with washers 8. One washer 8 abuts against the first support arm 31 and the printed part 2, and the other washer 8 abuts against the second support arm 32 and the printed part 2. The design of the washers 8 can eliminate the gap between the printed part 2 and the first support arm 31 and the second support arm 32, prevent the printed part 2 from wobbling from side to side, and further improve the stability of the printed part 2 in use.

[0045] See appendix Figure 5 -Appendix Figure 10 In Embodiment 1 and Embodiment 2, the screw sleeve 41 adopts a wing nut and the screw block 6 adopts a disc-shaped screw block. This design can increase the force points of the screw sleeve 41 and the screw block 6, making it convenient for users to turn the screw block 6 to drive the printed part 2 to rotate and switch the printing surface 20, and to make it convenient for users to turn the screw sleeve 41 to lock or loosen the printed part 2, further improving the ease of use.

[0046] See appendix Figure 1 -Appendix Figure 3 The pole 1 is made up of multiple sub-poles (not shown in the figure), or the pole 1 is a telescopic pole with an adjustable length.

[0047] Specifically, users can disassemble and assemble the sub-poles or retract the telescopic pole to shorten the pole body 1 to improve portability. When in use, users can assemble the sub-poles or extend the telescopic pole to lengthen the pole body 1 to ensure that the height position of the printed part 2 meets the requirements.

[0048] It should be noted that adjustable-length telescopic rods are existing products and come in various types, therefore, this utility model does not limit or describe their type and specific structure; on the other hand, a rod body 1 with a fixed length can also be used directly, and this utility model does not limit this either.

[0049] See appendix Figure 6 -Appendix Figure 10 and attached Figure 13 -Appendix Figure 14 The present invention also includes a spring plunger 7. The printed part 2 has a plurality of positioning holes 214 arranged in a circumferential array. The plurality of positioning holes 214 are arranged one-to-one with the plurality of printing surfaces 20. The spring plunger 7 is mounted on the fixing frame 3, and the pin head 72 of the spring plunger 7 can be engaged or disengaged from the positioning holes 214 one by one as the printed part 2 rotates.

[0050] Specifically, under normal circumstances, the pin 72 engages with the current positioning hole 214. When it is necessary to switch the printing surface 20, the locking member 4 is first released from the restriction on the printing part 2 before rotating the printing part 2. During the rotation of the printing part 2, the pin 72 will disengage from the current positioning hole 214 and engage with the next positioning hole 214. When the pin 72 strikes the printing part 2 and engages with the positioning hole 214, it can provide audible feedback to remind the user that the switching of the printing surface 20 has been completed. It can also limit the printing part 2 after the switching of the printing surface 20, ensuring that the printing surface 20 stably maintains its current orientation. This prevents the printing surface 20 of the printed body that has been relocked by the locking member 4 from having an angular deviation that would affect the marking accuracy, further improving the user experience.

[0051] Among them, as attached Figure 13 -Appendix Figure 14 As shown, the spring plunger 7 is an existing product, and there are various types of spring plungers 7 on the market. Therefore, this utility model does not limit this. For ease of understanding, in this embodiment, the spring plunger 7 includes a column 71, a pin 72, and a spring 73. The column 71 is threadedly connected to the fixing frame 3, and the preload is adjusted by the thread insertion depth. The column 71 has an outwardly opening movable cavity 710 inside. The pin 72 is movably disposed in the movable cavity 710 and located at the opening of the movable cavity 710. The spring 73 is disposed in the movable cavity 710 and abuts against the inner wall of the movable cavity 710 and the pin 72.

[0052] Specifically, when the printed part 2 is rotated, the printed part 2 will squeeze the pin head 72 to disengage from the current positioning hole 214. During this process, the spring 73 deforms and stores energy. When the pin head 72 aligns with the next positioning hole 214, the spring 73 releases energy and restores its original state, and drives the pin head 72 to engage with the positioning hole 214 to complete the limit.

[0053] See appendix Figure 5 -Appendix Figure 10 The printing surface 20 can be directly integrally formed onto the printed part 2. However, this integrally formed structure design means that when the manufacturer processes the pattern / text on the printing surface 20, the printed part 2 must be processed together, which makes the processing of the printing surface 20 difficult. To solve this problem, in this utility model, the printed part 2 includes a main body 21 and an ink-absorbing panel 22. The main body 21 is rotatably mounted on the fixing frame 3. The ink-absorbing panel 22 has multiple pieces arranged in a circumferential array on the main body 21. The printing surface 20 is formed on the ink-absorbing panel 22, and the locking member 4 is set corresponding to the main body 21.

[0054] Specifically, during production, the manufacturer can separately manufacture the ink absorption panel 22 and process the corresponding pattern / text on the printing surface 20 of the ink absorption panel 22, and then fix the ink absorption panel 22 to the main body 21. This design improves production convenience.

[0055] When in use, the user holds the rod 1, switches the printing surface 20, and locks the main body 21 by locking the locking piece 4. Then, the user can stick the printing surface 20 with colored liquids such as ink or water-based dye to carry out the marking operation.

[0056] Furthermore, the ink absorption panel 22 is detachably connected to the main body 21. With this design, users can choose to install the ink absorption panel 22 that needs to be replaced according to the marking requirements, which improves versatility. At the same time, users can also disassemble the ink absorption panel 22 for cleaning, which improves maintenance convenience.

[0057] The ink-absorbing panel 22 can be attached to the main body 21 by Velcro (not shown in the figure) / adhesive, or it can be fixed by screws (not shown in the figure). There are various disassembly and connection structures between the ink-absorbing panel 22 and the main body 21, and this utility model does not limit them.

[0058] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
