Technical Field

[0001] The utility model relates to the technical field of electric power signboards, in particular to a mounting fixture for electric power signboards. Background Art

[0002] The primary functions of power signage include providing reminders, warnings, and ensuring safe production. These signs remind people to identify and be alert to dangerous factors, ensuring that workers can avoid risks during operations, maintaining the reliable operation of the power grid, and ensuring stable power supply to thousands of households.

[0003] Usually, power signs are installed outdoors using mounting fixtures, and are therefore greatly affected by external environmental factors. The mounting fixtures often become loose and fall off due to rust, wear, wind, and other reasons, causing safety hazards such as injury to people, scratches on wires, scratches on insulators, and misleading of staff. Therefore, the applicant has made a useful design and found a solution to the above problems. The technical solution to be introduced below was produced in this context. Summary of the Invention

[0031] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] In the embodiments of the present invention, "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0034] Reference example Figures 1 to 5A mounting fixture for an electric power sign includes a sign 1, a first fixing frame 2, and a second fixing frame 3. Several first mounting holes 11 are provided on both sides of the sign 1, and the second fixing frame 3 is provided with a second fixing hole. The first mounting hole 11 is provided with a bolt 4, which passes through the first fixing frame 2 and the second mounting hole 31. The bolt 4 is threadedly connected with a nut 41 and abuts the end face of the second fixing hole. The end faces of the first mounting hole 11 and the second mounting hole 31 are provided with a countersink 5. The side wall of the countersink 5 is provided with a backstop groove 51. The countersink 5 is provided with a protective sleeve 6. The protective sleeve 6 is evenly distributed with several backstop blocks 61 with a dot as the axis, and is embedded in the backstop groove 51. An elastic member 7 is provided in the protective sleeve 6, and abuts the end faces of the bolt 4 and the nut 41. The protective sleeve 6 is provided with a cavity 66 for accommodating the bolt 4 and the nut 41, and abuts against each other. The stop block 61 is embedded in the stop groove 51 by interference fit, increasing the friction between the protective sleeve 6 and the countersunk hole 5; the elastic member 7 releases the elastic force to the bolt 4 and the nut 41, increasing the friction between the thread groove of the bolt 4 and the thread groove of the nut 41, and at the same time, further improving the friction between the stop block 61 and the stop groove 51. Through the above-mentioned structural design of increasing friction, and cooperating with the cavity 66, the nut 41 or the bolt 4 is prevented from loosening due to wind or vibration, and the protective sleeve 6 greatly reduces the erosion of rainwater at the connection between the bolt 4 and the nut 41, avoiding the reduction of the locking degree of the nut 41 and the bolt 4, ensuring the stable connection between the signboard 1 and the tower 8,

[0035] It is worth mentioning that the protective sleeve 6 of the second fixing hole is provided with a through hole 62 for the bolt 4 to pass through;

[0036] It is worth mentioning that an extension portion 21 is provided at one end of the first fixing frame 2, and the extension portion 21 is perpendicular to the first fixing frame 2. The extension portion 21 is provided with a fixing portion 22, and the fixing portion 22 is arranged opposite to the first fixing frame 2. The fixing portion 22 is provided with a threaded hole 23, and the threaded hole 23 is provided with a countersunk hole 5. The threaded hole 23 is used to cooperate with the bolt 4. The extension portion 21 plays the role of supporting the tower 8, and the fixing portion 22 provides support for the bolt 4 here.

[0037] It is worth mentioning that the first fixing frame 2 is provided with a limiting through hole 24 for the bolt 4 to pass through. By adjusting the position of the bolt 4 in the limiting through hole 24, the upper and lower positions of the signboard 1 can be changed.

[0038] It is worth mentioning that a contraction chamber 63 is provided at one end of the protective sleeve 6, and a cap body 64 is provided at the other end of the protective sleeve 6. When the protective sleeve 6 is separated from the countersunk hole 5, the outer wall diameter of the protective sleeve 6 is retracted by the contraction chamber 63, thereby separating from the countersunk hole 5. The cap body 64 facilitates the user to apply force to the protective sleeve 6.

[0039] It is worth mentioning that the cavity 66 is provided with a blind hole 65 for accommodating the elastic member 7. The elastic member 7 is configured as a spring. The blind hole 65 concentrates the force of the elastic member 7.

[0040] It is worth mentioning that the second fixing frame 3 is provided with a supporting portion 32, which is in a vertical relationship with the second fixing frame 3, and the supporting portion 32 plays a role in preventing separation after fixing;

[0041] It is worth mentioning that a first inclined surface 611 and a second inclined surface 612 are respectively provided on both sides of the stop block 61. When the protective sleeve 6 enters the countersunk hole 5, the first inclined surface 611 causes the contraction chamber 63 to contract toward the axial direction. When the protective sleeve 6 leaves the countersunk hole 5, the second inclined surface 612 causes the contraction chamber 63 to contract toward the axial direction.

[0042] The operating principle of the present invention is now described as follows:

[0043] Place the first fixing frame 2 against one side of the tower 8, with the fixing portion 22 engaged with the bottom of the tower 8. Rotate the nut 41 and push the second fixing frame 3 until the second fixing frame 3 abuts the other side of the tower 8. Continue rotating the nut 41 to form a clamping force between the first fixing frame 2 and the second fixing frame 3 to clamp the tower 8. Thread the bolt 4 into the threaded hole 23 and rotate the bolt 4 until its tip abuts the tower 8. This serves as the second connection point, increasing the stability of the connection between the signboard 1 and the tower 8.

[0044] Take the protective sleeve 6, put the cavity 66 on the outer wall of the nut 41 or the bolt 4, apply thrust to the protective sleeve 6, and shrink the contraction chamber 63 through the first inclined surface 611 to allow the stop block 61 to enter the countersunk hole 5, until the stop block 61 is embedded in the stop groove 51, and the installation of the protective sleeve 6 is completed.

[0045] The above design solution can enable the product to achieve the advantages of stable connection and reliable fixation.

[0046] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
