Detailed Description
Specific embodiments of the present utility model will be described below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the bolt 3 in a bolt-nut assembly for fixing an air conditioner external unit includes a stud 31 and a screw head 32. The screw head 32 may be a quadrangular prism as shown in fig. 1, or a hexagonal prism as shown in fig. 6 or a polygonal prism structure such as a triangular prism as shown in fig. 7. The stud 31 is sequentially provided with a first external thread 311, a second external thread 312 and a limiting part 313 from one end far away from the screw head 32 to one end close to the screw head 32, wherein the external diameter of the second external thread 312 is larger than that of the first external thread 311, two sides of the limiting part 313 are planes 314 parallel to each other, the distance between the two planes is consistent with that of the second external thread 312, and the distance between the two planes 314 is slightly smaller than the width of the waist-shaped mounting hole 11 of the air conditioner bracket 1, so that the limiting part 313 is embedded and clamped in the waist-shaped mounting hole 11, and is preferably slightly smaller than 1-2 mm. It should be noted that the elongated through holes are commonly used in the air conditioning bracket of the kidney-shaped mounting hole 11 and are used for adapting to the distances between the two connecting holes 211 of the base 21 of different air conditioning external units.
The center of the nut 4 is provided with a threaded hole 41 therethrough, and the threaded hole 41 is adapted to the first external thread 311. The edge of one end of the nut 4 is further provided with a blocking portion 422 protruding to the side face, the end face of the other end of the nut 4 is further provided with a gasket portion 43, the bottom face of the gasket portion 43 is provided with protruding lines, and the lines are a plurality of tooth-shaped protrusions 44 distributed on the bottom face of the gasket portion in an annular mode.
In the above structure, the threaded hole 41 of the nut 4 is adapted to be screwed with the first external thread 311 of the bolt 3, and the second external thread 312 of the bolt 3 is used to connect with the shock pad 5. The blocking part 42 at one end of the nut 4 can prevent the nut 4 from falling freely due to the blocking of the ball 62 in the sleeve 61 after the nut 4 is embedded in the sleeve 61 of the socket wrench, so that the situation that the nut 4 falls from high altitude during installation can be avoided, and the safety of installation operation and the efficiency of installation are improved; the pad portion 43 at the other end of the nut 4 and the texture structure arranged on the bottom surface thereof can play a role in increasing friction force between the nut 4 and the base 21 of the air conditioner external unit after the nut 4 is fastened, prevent the nut 4 from loosening, effectively ensure long-term stability of the air conditioner external unit, avoid loosening and even falling of the air conditioner external unit, and further improve durability and safety of the air conditioner external unit after being fixed. In addition, the limiting part 313 of the bolt 3 is correspondingly embedded in the kidney-shaped mounting hole 11 of the air conditioner bracket 1, so that two planes of the limiting part 313 can be clamped in the kidney-shaped mounting hole 11 of the air conditioner bracket 1, the bolt 3 cannot rotate under the limitation of the kidney-shaped mounting hole 11, and the bolt 3 is prevented from rotating simultaneously when the nut 4 is connected and rotated.
Referring to fig. 4 and 5, the specific installation process of the fixing air conditioner bracket of the present utility model is as follows:
s1: the bolt 3 passes through the kidney-shaped mounting hole 11 of the air conditioner bracket 1 from bottom to top until the screw head 32 is propped against the bottom edge of the kidney-shaped mounting hole 11, so that the first external thread 311 and the second external thread 312 pass through the kidney-shaped mounting hole 11, and the limiting part 313 is embedded in the kidney-shaped mounting hole 11;
s2: fitting screw-coupling the shock pad 5 to the second external screw thread 312 so as to be closely attached to the upper end edge of the kidney-shaped mounting hole 11;
s3: correspondingly sleeving a connecting hole 211 on the base 21 of the air conditioner external unit on a first external thread 311 of the bolt 3;
s4: the nut 4 is pressed into the sleeve 61 of the wrench until the blocking part 42 is blocked on the ball in the sleeve 61, so that the nut 4 cannot fall out of the sleeve 61, then the wrench is operated until the threaded hole 41 of the nut 4 is correspondingly sleeved on the first external thread 311, and the wrench is rotated until the nut 4 is fastened on the base 21 of the air conditioner external unit, and then the fixing of the air conditioner external unit by the bolt 3 and the nut 4 can be completed.
In the above-mentioned installation step, step S1 and S2 can be completed indoors, namely, before fixing the air conditioner bracket 1, the bolt 3 is installed and fixed to the air conditioner bracket 1, which is more convenient and faster, and is safer than the traditional way of installing bolts and nuts completely at outdoor high altitude, and simultaneously, the bolt 3 and the shock pad 5 can be conveniently installed and fastened on the air conditioner bracket 1, so that the overall firmness degree can be improved. When the air conditioner outdoor unit is fixed, the limit part 313 of the bolt 3 is limited by the waist-shaped mounting hole 11 of the air conditioner bracket 1 and cannot rotate, and the bolt 3 is limited by the connecting shock pad 5 at the upper end of the limit part 313 so as not to fall. Therefore, when the nut 4 is installed and locked, only one hand is needed to operate the wrench, the other hand is not needed to fix the bolt 3, the installation is very convenient, and the installation efficiency can be effectively improved. And for an installer who installs the air conditioner outdoor unit at outdoor high altitude, the other hand can be used for stabilizing the body, such as holding a lifting rope and the like, so that the structure of the utility model can effectively improve the safety factor of the operation of the installer.
The foregoing is merely illustrative of specific embodiments of the present utility model, but the design concept of the present utility model is not limited thereto, and any insubstantial modification of the present utility model by using the design concept shall fall within the scope of the present utility model.
