Description

Technical Field

[0001] The present application relates to the field of luminous characters, and in particular to a fixing structure and luminous characters. Background Art

[0002] Illuminated characters are luminous signs, mainly used in dark weather, which make the signs more conspicuous and play an important role in promoting enterprises, shops, exhibitions, etc. Existing luminous characters mainly consist of a character shell, a transparent plate and a bottom plate for installing LED light-emitting modules. The existing fixing method of the character shell and the transparent plate is to fix the transparent plate with hot melt glue, and then use glass glue to seal the contour. Due to the large metal edging range of the character shell, a lot of manpower is required to apply glue.

[0003] However, as time goes by, the adhesive fixing method has a short service life, and the adhesive parts are prone to cracking and aging. This leads to problems such as increased processing costs, long processing time, low reliability of various components of the luminous characters, and high later maintenance costs. Utility Model Content

[0004] In order to improve the installation efficiency of luminous characters, shorten the installation time, and improve the stability between the various components of the luminous characters, the present application provides a fixing structure and a luminous character.

[0006] A fixing structure comprises a nail handle, a nail cap arranged on the bottom surface of the nail handle, a nail body arranged on the bottom surface of the nail cap and a welding point arranged on the bottom surface of the nail body.

[0007] By adopting the above technical solution, the nail handle is used to clamp the gun head of the nail welding machine, the nail cap is used to lock the object to be fixed, and the nail body is used to be inserted into the object to be fixed. The gun head of the nail welding machine clamps the nail handle, and then presses down at the reserved opening of the object to be fixed, and presses the power switch of the nail welding machine. The instantaneous high temperature generated by the electrode is used to introduce the welding point and melt the welding point. At this time, the fixed structure is welded to the bottom metal plate, and the nail cap fixes the object to be fixed on the metal plate. The application has a small welding point and no obvious welding marks on the surface. At the same time, the operation is simple and the fixing effect is good.

[0008] Preferably, the diameter of the nail cap is larger than the width of the nail handle or the nail body.

[0009] Preferably, one or more welding points are provided.

[0011] Preferably, the cross-section of the nail body along the center line is trapezoidal in shape.

[0012] Preferably, the welding point is convex.

[0013] The present application also provides a luminous character, which adopts the following technical solution:

[0014] A luminous character comprises a character shell, a light-transmitting plate arranged at one open end of the character shell, a bottom plate arranged at the other open end of the character shell and any of the above-mentioned fixing structures, wherein the fixing structure is used to position the light-transmitting plate on the character shell, and a pressing edge is provided along the inner wall at one end of the character shell for positioning the light-transmitting plate.

[0015] By adopting the above technical solution, the fixing structure fixes the light-transmitting plate and the pressing edge, thereby improving the stability of the light-transmitting plate on the letter case and improving the fixing efficiency.

[0016] Preferably, the light-transmitting plate is provided with an insertion port along the side edge, which is within the coverage range of the pressing edge; the nail body is located in the insertion port; and the welding point is connected to the pressing edge.

[0017] By adopting the above technical solution, the plug interface is used for the nail body to be inserted, which is convenient for the soldering point to contact with the pressing edge, and convenient for the fixed structure to be welded on the pressing edge. The nail cap locks the light-transmitting plate, thereby improving the stability of the light-transmitting plate on the letter shell.

[0018] Preferably, the width of the inserting interface is smaller than the width of the pressing edge, and the width of the inserting interface is smaller than the width of the nail cap.

[0019] Preferably, the side wall of the bottom plate is provided with fixing screws, and the fixing screws are used to mount the bottom plate on the character case.

[0020] By adopting the above technical solution, the fixing screws are used to fix the bottom plate on the character shell, thereby improving the stability of the bottom plate on the character shell.

[0021] In summary, the fixed structure can effectively reduce the welding range and prevent welding marks from penetrating the letter shell.

[0028] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0029] Embodiment 1:

[0030] The present application embodiment discloses a fixing structure. Figure 1 , including a nail handle 1, a nail cap 2 fixedly mounted on the bottom surface of the nail handle 1 and used to lock and position the object to be fixed, a nail body 3 fixed on the bottom surface of the nail cap 2 and used to be embedded in the object to be fixed, and a welding point 4 fixed on the bottom surface of the nail body 3. The nail cap 2 of the present application is integrally formed with the nail handle 1. In the existing implementation process, the nail cap 2 can be set to a detachable mode as needed. The detachable connection mode can be a threaded connection. An external thread is provided on the outer wall of the nail handle 1, and an internal thread matching the external thread of the nail handle 1 is provided on the inner wall of the nail cap 2. One or more welding points 4 are provided. In the embodiment of the present application, when one welding point 4 is provided, the center points of the nail handle 1, the nail cap 2, the nail body 3 and the welding point 4 are all on the same straight line, which can improve the welding stability. When multiple welding points 4 are provided, multiple welding points 4 are evenly distributed on the bottom surface of the nail body 3 in a circular ring shape, which is convenient for improving the welding firmness; the arrangement of the welding points 4 can be arranged in a matrix or scattered according to the needs of the welding personnel. The welding spot 4 is convex, and the cross-sectional shape of the convex is semicircular, rectangular, conical, trapezoidal, etc. The diameter of the nail cap 2 is larger than the diameter of the nail handle 1, and the diameter of the nail cap 2 is larger than the diameter of the nail body 3, so as to improve the positioning effect of the nail cap 2. In the embodiment of the present application, the diameter of the nail handle 1 is smaller than the diameter of the nail body 3, and the diameter of the nail body 3 is smaller than the diameter of the nail cap 2. The nail handle 1 is convenient for clamping by the nail welding machine, and the nail body 3 is convenient for better insertion into the object to be fixed; in the specific implementation process, the diameter of the nail handle 1 can be larger than the diameter of the nail body 3 or the diameter of the nail handle 1 is consistent with the diameter of the nail body 3. The cross-sectional shape of the nail body 3 along the center line is square, which is convenient for the nail body 3 to be directly inserted into the reserved hole of the object to be fixed, and improves the stability of the nail body 3 in the object to be fixed.

[0031] Reference Figure 1 In the embodiment of the present application, the nail cap 2 is circular. In the specific implementation process, the nail cap 2 can be elliptical, rectangular, square or special-shaped, so that the nail cap 2 can lock the object to be fixed.

[0032] Reference Figure 1The nail cap 2 of the present application can also be set to a 360° rotation state. A groove for positioning the nail cap 2 is opened along the circumference of the outer wall of the nail body 3. The nail cap 2 is in a circular ring shape or a circular hole is opened in the center of the nail cap 2. The inner ring end of the nail cap 2 is located in the groove, which is convenient for expanding the force-bearing area between the nail body 3 and the object to be fixed, so that the nail cap 2 can press the object to be fixed more firmly.

[0033] Reference Figure 1 , the nail welding machine clamps the nail handle 1, inserts the nail body 3 into the reserved socket of the object to be fixed, presses the power switch of the nail welding machine, uses the instant high temperature generated by the electrode to introduce the welding point 4 and melt the welding point 4 on the metal plate, and then the nail cap 2 locks the object to be fixed to improve the stability of the object to be fixed on the metal plate. Then release the clamp of the nail welding machine and detach the nail handle 1. The installation of the fixed structure of the present application is completed. The welding point 4 of the fixed structure of the present application is small, the welding is stable, and there is no obvious welding mark directly opposite the welding position of the metal plate, which ensures the aesthetics of the luminous characters and the fixing effect of the fixed structure on the object to be fixed.

[0034] Reference Figure 2 , during the use of the fixing structure of the present application, when the thickness of the object to be fixed is inconsistent with the height of the nail body 3. When the height of the nail body 3 is less than the thickness of the object to be fixed, the nail body 3 is pressed down by a nail welding machine. The downward pressure of the nail welding machine is greater than the toughness of the nail cap 2. The nail cap 2 automatically bends under pressure. The greater the height difference between the object to be fixed and the nail body 3, the greater the bending angle of the nail cap 2. The nail cap 2 bends and positions the object to be fixed, effectively ensuring the locking effect of the nail cap 2 on the object to be fixed; on the contrary, the smaller the height difference between the object to be fixed and the nail body 3, the smaller the bending angle of the nail cap 2. When the welding point 4 contacts the metal plate, the power switch is turned on, the welding point 4 melts and is welded to the pressing edge 8. While the nail cap 2 locks the object to be fixed, it uses the bending toughness of the nail body 3 to press the object to be fixed, effectively solving the problem of inconsistent thickness of the customized object to be fixed and height of the nail body 3.

[0035] Embodiment 2:

[0036] The difference between this embodiment and the first embodiment is that, referring to Figure 3 , the cross-sectional shape of the nail body 3 along the neutral line is trapezoidal. When the cross-sectional shape of the nail body 3 is an inverted trapezoid, the cross-sectional area of ​​the nail body 3 gradually decreases away from the nail cap 2, which is used to provide an escape space, so that the nail body 3 can be inserted into the reserved hole of the object to be fixed. In the specific implementation process, the cross-sectional shape of the nail body 3 can also be a regular trapezoid, and the cross-sectional area of ​​the nail body 3 gradually increases away from the nail cap 2, which is used to increase the force-bearing area of ​​the welding point 4.

[0037] The present application also discloses a luminous character. Figure 4 and Figure 5, including a character shell 5, a light-transmitting plate 6 installed at one open end of the character shell 5, a bottom plate 7 installed at the other open end of the character shell 5 and a fixing structure for fixing the light-transmitting plate 6 on the character shell 5, a light strip is installed on the bottom plate 7, and the shape of the character shell 5 can be set as needed.

[0038] Reference Figure 4 and Figure 5 , the open end of the character shell 5 is provided with a pressure edge 8 for positioning the light-transmitting plate 6 along the inner wall. In the embodiment of the present application, the width of the pressure edge 8 is between 5mm and 15mm (including the end value). In the existing implementation, the pressure edge 8 of other sizes can be set according to the size of the character shell 5. The light-transmitting plate 6 is provided with a plurality of plug-in ports 9 located within the coverage range of the pressure edge 8 along the side edge. The nail body 3 is located in the plug-in port 9. The welding nail machine heats the solder joint 4, and the solder joint 4 melts on the pressure edge 8 and is fixed to the pressure edge 8. The nail cap 2 fixes the light-transmitting plate 6 on the character shell 5 to improve the stability of the light-transmitting plate 6 on the character shell 5. The width of the plug-in port 9 is smaller than the width of the pressure edge 8 to avoid the phenomenon of welding leakage of the solder joint 4 caused by the plug-in port 9 being too large. The width of the plug-in port 9 is smaller than the width of the nail cap 2, which facilitates the nail cap 2 to lock the light-transmitting plate 6. The side wall of the bottom plate 7 is installed with fixing screws, and the fixing screws install the bottom plate 7 on the character shell 5.

[0039] The installation method of the luminous characters of the present application is simple. First, place one end of the character shell 5 where the edge pressing 8 is installed on the operating table, and then place the light-transmitting plate 6 in the character shell 5. At this time, the edge pressing 8 is located on the bottom surface of the light-transmitting plate 6. The installer holds the nail welding machine, and the gun head of the nail welding machine clamps the nail handle 1, presses the nail body 3 down at the plug interface 9, presses the power switch, and the electrode generates instant high temperature to introduce the welding point 4. The welding point 4 melts on the edge pressing 8, and the fixed structure is welded to the edge pressing 8. At this time, the nail cap 2 locks the light-transmitting plate 6, loosens the clamp of the nail welding machine, and detaches from the nail handle 1. Then, according to this step, all the plug interfaces 9 opened on the light-transmitting plate 6 are installed on the fixed structure. At this time, the installation of the light-transmitting plate 6 is completed. Then place the bottom plate 7 on the character shell 5, and fix the bottom plate 7 on the character shell 5 with fixing screws.

[0040] The luminous characters of the present application are quick to install, have good stability, and effectively shorten the installation time between various components.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
