[0001] This utility model relates to the fields of engineering construction and traffic management technology, specifically a warning sign installation structure that is easy to replace. Background Technology

[0002] Warning signs originally refer to signs used to provide reminders and warnings. The content and application of warning signs vary across different industries and environments. However, in municipal management, the use of warning signs is even more widespread. In order to enhance the management of parks, flower beds, lawns, and roads, warning signs with warning and reminder information are often used to guide and remind the behavior of the general public, thereby playing a vital role in urban civilization construction and municipal management.

[0003] Traditional warning signs have a fixed structure, making it extremely difficult to change the warning content once installed, requiring the reinstallation of a new sign. Furthermore, signs of different sizes require custom-made frames to fit their dimensions, resulting in poor adaptability of the installation structure. Utility Model Content

[0004] The purpose of this utility model is to provide a warning sign installation structure that is easy to replace, in order to solve the problems of the traditional warning sign structure in the prior art being difficult to change the warning content and having poor applicability of the installation structure.

A first telescopic component is provided between the two lower plates. The first telescopic component can be adjusted in the left and right directions so as to adjust the length of the mounting frame in the left and right directions by adjusting the position of the two lower plates in the left and right directions.

[0007] The lower plate is L-shaped and includes vertically connected vertical bars and horizontal bars, with the first telescopic component disposed between the two horizontal bars;

[0008] The mounting frame also includes an upper plate extending in the left-right direction. The upper plate is provided with a second telescopic component, which can be adjusted in the left-right direction to adjust the length of the upper plate in the left-right direction.

[0009] The mounting frame is adjustable in length in the vertical direction. The top of the vertical rod of the lower plate and the two ends of the upper plate are respectively provided with a third telescopic component. The third telescopic component can be adjusted in the vertical direction to adjust the length of the mounting frame in the extension direction of the vertical rod of the lower plate.

[0010] Preferably, the first telescopic component includes a left slot fixed on the left vertical bar, a right slot fixed on the right vertical bar, and an extension plate inserted between the left slot and the right slot. The first telescopic component also includes a left positioning slot on the left horizontal bar and a right positioning slot on the right horizontal bar. The left positioning slot is provided with a first clamping structure for fixing the extension plate, and the right positioning slot is provided with a second clamping structure for fixing the extension plate.

[0011] Preferably, the upper plate includes a left insert plate and a right insert plate, and the second telescopic component is disposed between the left insert plate and the right insert plate;

[0012] The second telescopic component includes a left slot in the left insert plate, a right slot in the right insert plate, and a limiting plate that is adapted to be inserted into the left and right slots. The limiting plate is respectively provided with a fixing structure between itself and the left and right insert plates.

[0013] Preferably, the fixing structure includes a left limiting groove formed on the left insert plate and a right limiting groove formed on the right insert plate. Upper bolts are respectively provided on the left limiting groove and the right limiting groove, so as to fix the two ends of the limiting plate relative to the left insert plate and the right insert plate respectively by means of the upper bolts.

[0014] Preferably, the third telescopic component includes a receiving groove, a connecting rod, and an adjusting structure;

[0015] The receiving groove is formed on the vertical rod, and the connecting rod is fixed on the left and right insert plates respectively. The connecting rod is set in the receiving groove and can retract relative to the receiving groove.

[0016] Preferably, the adjustment structure includes a lead screw rotatably disposed in a receiving groove and a threaded hole formed in a connecting rod, wherein the lead screw is threadedly adapted to the threaded hole, and a knob is provided at the end of the lead screw.

[0017] Preferably, the first support assembly includes a first support leg rotatably connected to the outside of the vertical rod and a first extension leg slidably inserted into the first support leg.

Detailed Implementation

[0031] The following description, in conjunction with the accompanying drawings, further illustrates a specific embodiment of the easily replaceable warning sign installation structure of this utility model.

[0032] like Figure 1-7 As shown, an easy-to-replace warning sign installation structure is mainly used to place warning signs of different sizes, and the warning signs are placed on the ground for use through this device; at present, warning signs are installed on the ground, but because the size of the warning frame is fixed, it cannot be used for warning signs of different sizes, resulting in poor applicability.

[0033] In this embodiment, the frame includes a mounting frame for installing warning signs and a first support component 8 and a second support component 9 hinged to the mounting frame.

[0034] like Figure 1 and Figure 2 As shown, the mounting frame is adjustable in length in the left and right directions. The mounting frame includes lower plates 102 arranged symmetrically on the left and right. A first telescopic component is provided between the two lower plates 102. The first telescopic component can be adjusted in the left and right directions. By adjusting the position of the two lower plates 102 in the left and right directions, the length of the mounting frame in the left and right directions can be adjusted. The operator can manually pull the two lower plates 102 to extend them along the extension plate 101 to achieve the effect of adjusting the horizontal length. This allows for the placement of warning signs that are too wide horizontally.

[0035] The lower plate 102 is L-shaped and includes vertically connected vertical bars and horizontal bars, with a first telescopic assembly disposed between the two horizontal bars.

[0036] The first telescopic assembly includes a left slot fixed on the left vertical bar, a right slot fixed on the right vertical bar, and an extension plate 101 inserted between the left slot and the right slot. The first telescopic assembly also includes a left positioning slot on the left horizontal bar and a right positioning slot on the right horizontal bar. A first clamping structure for fixing the extension plate 101 is provided in the left positioning slot, and a second clamping structure for fixing the extension plate 101 is provided in the right positioning slot.

[0037] In this embodiment, the first tightening structure and the second tightening structure respectively include a lower left bolt and a lower right bolt. The lower left bolt passes through the left positioning groove and is threaded to the extension plate 101. The lower right bolt passes through the right positioning groove and is threaded to the extension plate 101. When the lower plate 102 is stretched along the extension plate 101, the lower left bolt and the lower right bolt on the extension plate 101 can move along the left positioning groove and the right positioning groove respectively. When the lower left bolt and the lower right bolt are tightened, the lower plate 102 and the extension plate 101 can be connected. When the length of the two lower plates 102 is sufficient for the warning sign to be placed, the lower left bolt and the lower right bolt are tightened to lock the lower plate 102 and the extension plate 101.

[0038] like Figure 2 As shown, the mounting frame also includes an upper plate 201 extending in the left and right direction. The upper plate 201 is provided with a second telescopic component, which can be adjusted in the left and right direction to adjust the length of the upper plate 201 in the left and right direction. When the upper plate 201 moves to both sides under the action of the lower plate 102, the two upper plates 201 will move along the limiting plate 6.

[0039] The upper plate 201 includes a left insert plate and a right insert plate, and the second telescopic component is disposed between the left insert plate and the right insert plate. The second telescopic component includes a left slot in the left insert plate, a right slot in the right insert plate, and a limiting plate 6 that is adapted to be inserted into the left slot and the right slot. The limiting plate 6 is provided with a fixing structure between itself and the left insert plate and the right insert plate, and the fixing structure can lock the limiting plate 6 to the left insert plate and the right insert plate.

[0040] Specifically, the fixing structure includes a left limiting groove on the left insert plate and a right limiting groove on the right insert plate. Upper bolts 701 are respectively provided on the left and right limiting grooves to fix the two ends of the limiting plate 6 relative to the left and right insert plates respectively. When the two upper plates 201 move, they will drive the upper bolts 701 to move along the left and right limiting grooves. When the distance is appropriate, the upper bolts 701 are tightened to lock the plate.

[0041] While tightening the lower left and lower right bolts, the upper bolt 701 can also be tightened, so that the lower plate 102 and the upper plate 201 are locked together by the lower left and lower right bolts and the upper bolt 701, thereby improving the stability of the lower plate 102 and the upper plate 201 and making the warning sign more secure.

[0042] In other embodiments, the upper limiting plate 6 may not be provided between the two upper plates 201. As long as the upper plate 201 moves with the lower plate 102, the upper limiting plate 6 can prevent the upper plate 201 from tilting when it moves. Moreover, the connection of the upper limiting plate 6 can make the two upper plates 201 more closely connected.

[0043] like Figure 3 and Figure 4 As shown, the mounting frame is adjustable in length in the vertical direction. A third telescopic component is provided at the top of the vertical rod of the lower plate 102 and at both ends of the upper plate 201. This third telescopic component can be adjusted vertically to adjust the length of the mounting frame in the direction of the vertical rod extension of the lower plate 102. Driven by the third telescopic component, the mounting frame can be adjusted vertically to increase its length, making it suitable for excessively tall warning signs.

[0044] Specifically, the third telescopic component includes a receiving groove, a connecting rod, and an adjustment structure. The receiving groove is located on the vertical rod, and the connecting rod is fixed to the left and right insert plates respectively. The connecting rod is located in the receiving groove and can retract relative to the receiving groove. The adjustment structure includes a lead screw 202 rotatably located in the receiving groove and a threaded hole located in the connecting rod. The lead screw 202 is threadedly fitted to the threaded hole. A knob is located at the end of the lead screw 202. Rotating the knob causes the lead screw 202 to rotate. Since the lead screw 202 is threadedly fitted to the threaded hole, it can drive the connecting rod to move up and down along the receiving groove, thereby realizing the adjustment of the vertical direction of the mounting frame.

[0045] By cooperating with the first support component 8 and the second support component 9, the mounting frame can be placed firmly on the ground, thereby improving the stability of the mounting frame.

[0046] Specifically, the first support assembly 8 includes a first support leg 801 rotatably connected to the outside of the vertical rod and a first extension leg 802 slidably inserted into the first support leg 801. The first support leg 801 has a modular hole, and the first extension leg 802 has a through hole. The first support leg 801 and the first extension leg 802 are fixed by fasteners that pass through the through hole and the modular hole in sequence. In this embodiment, when the modular hole on the first support leg 801 matches the through hole, a locking bolt can be inserted to fix the first extension leg 802 and the first support leg 801.

[0047] In other embodiments, such as Figure 7 As shown, a first spring buckle 10 is fixedly provided on the first extension leg 802, and a plurality of first locking holes 11 are provided on the first support leg 801 at intervals. When the first spring buckle 10 engages with the first locking holes 11, the first extension leg 802 and the first support leg 801 are locked together.

[0048] The second support assembly 9 includes a second support leg 901 rotatably connected to the middle of the vertical rod and a second extension leg 902 slidably inserted into the second support leg 901. The second support leg 901 has a modular hole, and the second extension leg 902 has a through hole. The second support leg 901 and the second extension leg 902 are fixed by fasteners that pass through the through hole and the modular hole in sequence. In this embodiment, the connection principle is the same as that of the first support assembly 8. When the modular hole on the second support leg 901 matches the through hole, a locking bolt can be inserted to achieve a fixed connection between the second support leg 901 and the second extension leg 902.

[0049] In other embodiments, such as Figure 6 As shown, the second extension leg 902 is slidably inserted into the second support leg 901. A second spring buckle 12 is fixedly provided on the second extension leg 902, and a second locking hole 13 is provided on the second support leg 901. The second spring buckle 12 engages with the second locking hole 13, so that the second support leg 901 and the second extension leg 902 are connected. When the second spring buckle 12 and the second locking hole 13 are adapted, the second support leg 901 and the second extension leg 902 can be connected.

[0050] like Figure 1-4 As shown, a support rod 14 is provided between the two second support legs 901. The length of the support rod 14 is adjustable in the left and right directions, and both ends of the support rod 14 are fixedly connected to the second support legs 901 respectively.

[0051] like Figure 4 As shown, the bottom of the second extension leg 902 is fixed with a nail 15, which can be placed on the ground or erected by being driven into the ground.

[0052] Working principle: The operator manually pulls the two lower plates 102 to extend them along the extension plate 101, thereby achieving the effect of lateral length adjustment. During the pulling process, the lower plates 102 can drive the two upper plates 201 to move along the limiting plate 6. Then, the knob is turned, which drives the lead screw 202 to rotate, causing the connecting rod to move up and down along the receiving groove. After adjustment, the warning sign is placed in the installation frame. The above operation is then repeated to lock the warning sign in place by the lower plates 102 and the upper plates 201. After installation, the first extension leg 802 and the second extension leg 902 are extended from the first support leg 801 and the second support leg 901 respectively and fixed to ensure the stable use of the installation frame.

[0053] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
