[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] The present application embodiment discloses a multifunctional grille fixing device, referring to Figure 1 and Figure 2 The grille fixing device includes a clip 1, which is made of a circular metal plate by stamping and has a plate surface protruding to one side. The plate surface of the clip 1 on the concave side is integrally formed with an anti-skid column 2. A plurality of anti-skid columns 2 are arranged and are arranged in a "cross" shape along the diameter of the plate surface of the clip 1. The anti-skid column 2 protrudes from the edge of the clip 1 away from one end of the clip 1.

[0033] Reference Figure 2A fixing hole 11 is provided at the center of the plate surface of the clip 1, a bolt 3 is passed through the fixing hole 11, a threaded hole 31 is provided on the bottom surface of the screw portion of the bolt 3 toward the big head end, a nail 4 is threadedly connected to the threaded hole 31, and a section of the peripheral wall of the nail 4 close to the bolt 3 is processed to form a threaded section 41 that matches the inner wall of the threaded hole 31.

[0034] When using the present grille fixing device, the staff will drive the tip of the nail 4 into the support beam through the grille gap of the grille plate according to the fixing position of the grille, and fix it, so that the bolt 3 passes through the fixing hole 11 of the clip 1, and the clip 1 is placed above the nail 4 parallel to the plate surface of the grille plate, and the position of the clip 1 is fine-tuned so that the anti-skid column 2 can be inserted into the grille gap, and the bolt 3 is turned so that the threaded hole 31 at the bottom is sleeved and threadedly connected to the threaded section 41 of the nail 4. At this time, the anti-skid column 2 can prevent the clip 1 from rotating with the bolt 3, and at the same time prevent the clip 1 from sliding on the plate surface of the grille plate, so that the staff can fix the grille plate.

[0035] Reference Figure 2 A spring washer 5 is sleeved on the side where the bolt 3 contacts the clip 1, and the outer diameter of the spring washer 5 is equal to the outer diameter of the large end of the bolt 3. When the grille fixing device is used, when the staff rotates the bolt 3 to clamp the clip 1, the spring washer 5 is compressed as the bolt 3 rotates and generates a reverse elastic force, which makes it easy for the staff to judge the tightening degree of the bolt 3 according to the reaction force generated when the spring washer 5 is compressed, and reduces the possibility of thread slippage caused by excessive tightening force of the bolt 3.

[0036] Reference Figure 2 The opening of the threaded hole 31 is processed inward to form a chamfer. When the grid fixing device is used, it is inconvenient for the staff to align the threaded hole 31 with the threaded section 41 of the nail 4 because the clip 1 blocks the line of sight. The chamfer formed by the processing of the threaded hole 31 can facilitate the threaded section 41 of the nail 4 to slide into the threaded hole 31, so that the staff can tighten the bolt 3.

[0037] Reference Figure 2 , a section of the peripheral wall of the bolt 3 near the nail 4 is processed to form an external thread 32. When using the grille fixing device, the clip 1 is placed at the connection between the two grille plates and the bolt 3 is passed through the fixing hole 11, and then the fixing hole 11 of the other clip 1 is sleeved on the end of the bolt 3 processed to form the external thread 32, so that the two clips 1 are formed with the anti-skid column 2 on one side facing each other, and the anti-skid columns 2 of the two clips 1 are respectively inserted into the grille gaps on the two side surfaces of the two grille plates, and the two clips 1 are fixed using nuts that can be threadedly connected with the external thread 32. The external thread 32 can increase the way in which the grille fixing device fixes the grille plate, which is convenient for the staff to firmly fix the grille plate according to different positions.

[0038] Reference Figure 2The bolt 3 is provided with an anti-slip groove 61 on the peripheral wall near the clamping piece 1. Two anti-slip grooves 61 are provided and are respectively located at the two ends of the diameter of the bolt 3. An anti-slip block 6 is slidably arranged in the anti-slip groove 61. The anti-slip block 6 is in a right-angled triangle and can be completely embedded in the anti-slip groove 61. Two adjacent right-angled surfaces of the anti-slip block 6 are located in the anti-slip groove 61. The bottoms of the two anti-slip grooves 61 are connected by a connecting hole, and an elastic member 62 is arranged in the connecting hole. In this embodiment, the elastic member 62 is a spring, and the two ends of the elastic member 62 are respectively fixed to the two anti-slip blocks 6 on the opposite sides. When the elastic member 62 is in an extended state, the two anti-slip blocks 6 are respectively located in the two anti-slip grooves 61.

[0039] When using the present grille fixing device, after the bolt 3 passes through the fixing hole 11 of the clip 1, the clip 1 continues to move toward the big head end of the bolt 3. When the clip 1 moves to above the anti-slip groove 61, the anti-slip block 6 can abut against the fixing hole 11 of the clip 1. The clip 1 pushes the anti-slip block 6 to embed into the anti-slip groove 61 and compresses the elastic member 62. When the clip 1 moves to fit the big head end of the bolt 3, the elastic force of the elastic member 62 will push the anti-slip block 6 to protrude from the anti-slip groove 61 and limit the clip 1, which can prevent the clip 1 from falling off the bolt 3, making it convenient for the staff to move the position of the bolt 3 and the clip 1 when fixing the grille plate, and to align the threaded hole 31 of the bolt 3 with the threaded section 41 of the nail 4 and tighten it.

[0040] Reference Figure 2 The edge of the clip 1 is integrally formed with an anti-slip strip 12, which is arranged along the edge of the clip 1, and the edge of the anti-slip strip 12 is bent toward the bolt 3. When the grille fixing device is used, the anti-slip strip 12 can prevent the edge of the clip 1 from moving on the grille plate, ensuring the stability of the clip 1 when tightening the bolt 3, and facilitating the worker to tighten the threaded hole 31 of the bolt 3 with the threaded section 41 of the nail 4.

[0041] Reference Figure 3 The inner wall of the fixing hole 11 is processed to form fastening teeth 13, which are in the shape of a right triangle and whose right angle sides are connected to the inner wall of the fixing hole 11. The fastening teeth 13 are sequentially arranged along the inner wall of the fixing hole 11. When the grille fixing device is used, the fastening teeth 13 can prevent the bolt 3 from rotating in the opposite direction, and the matching clip 1 and the anti-skid column 2 can prevent the bolt 3 from rotating in the opposite direction and loosening, thereby ensuring the stability of the grille fixing device fixing the grille plate.

[0042] Reference Figure 3 The plate surface of the clip 1 on one side of which the anti-skid column 2 is provided is integrally formed with a reinforcing rib 14, and the reinforcing rib 14 is arranged in a "cross" shape along the anti-skid column 2 near one end of the clip 1. When the grille fixing device is used, the reinforcing rib 14 can increase the plate surface strength of the clip 1, ensure that the clip 1 can firmly clamp the grille plate, increase the overall structural strength of the grille fixing device, and ensure the stability of the fixing device to fix the grille plate.
