Description

Technical Field

[0001] This invention relates to the field of installation and fixing technology for refrigeration equipment components, specifically a clamping and fixing device for refrigeration equipment installation parts. Background Technology

[0002] Refrigeration equipment, as the name suggests, is mainly used for cooling. Of course, there are many kinds of refrigeration equipment nowadays. They can be divided into many categories according to the usage scenario, purpose and effect. In daily life, the refrigeration equipment used is mainly air conditioners and electric fans.

[0003] Electric fans, as a common daily cooling device, are used very frequently in summer, almost every day. The principle of electric fans is mainly based on the motor driving the fan blades to rotate to achieve their main function. The protective structure on electric fans is mainly the grille structure at the fan blade position. Moreover, all electric fans currently use a two-part structure for the grille, that is, two semi-circular grille structures are assembled. During assembly, a plastic strip is used in conjunction with bolts and nuts to lock and fix the two grilles.

[0004] There are some problems and defects in the assembly and fixing of the above-mentioned grid cover structure during use, such as:

[0005] When electric fans are not in use, a lot of dust accumulates on their blades and grilles. When used in the summer, these impurities become sticky and need to be cleaned. This requires disassembling the grille structure and cleaning the blades and grille structure. Reassembling is quite troublesome and difficult. The plastic strips are difficult to maintain their shape in the initial state. When fitting them onto the two halves of the grille structure, it takes a lot of time just to adjust the grille position and fit the plastic strips. The key issue is that the plastic strips cannot quickly fix the two grille structures together and are too easy to misalign.

[0006] In addition, after it is fixed, it needs to be tightened with auxiliary tools such as wrenches and screwdrivers. In this process, apart from professional assembly operators, it is not only time-consuming and laborious for a normal family to assemble, but also requires the cooperation of multiple people.

[0007] Therefore, we propose a clamping and fixing device for refrigeration equipment mounting parts to solve the above problems. Summary of the Invention

[0008] The purpose of this invention is to provide a clamping and fixing device for mounting parts of refrigeration equipment, so as to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] A clamping and fixing device for mounting parts of a refrigeration equipment includes a first fixing ring and a second fixing ring. A fastening groove is provided on one side of the first fixing ring, and an insertion ring is provided on one side of the second fixing ring. Locking mechanisms are provided on the outer surfaces of both the first fixing ring and the second fixing ring.

[0011] The locking mechanism mainly includes a protruding strip, a rotating plate, and a locking plate. The protruding strip is fixedly installed on the outer side wall of the first fixing ring and the second fixing ring. The rotating plate is installed between the two protruding strips. The locking plate is fixedly installed at the end of the rotating plate.

[0012] Preferably, both the first and second fixing rings have annular grooves in the middle of their opposite sides. These annular grooves are fastened to the end face of the grille structure. The side of the clamping plate has an annular groove of the same size as the annular groove. When the clamping plate is moved to a vertical position, the annular groove can wrap around and secure the ring structure of the grille from the other side.

[0013] Preferably, a slide is provided on the side opposite to the protrusion, and a piston block is movably engaged in the inner cavity of the slide.

[0014] Preferably, each of the piston blocks has a horizontal bolt structure fixedly connected to its opposite side surface, and holes adapted to the horizontal bolt structure are provided on both sides of the rotating plate. One end of the horizontal bolt structure is engaged in the hole on the side of the rotating plate, so that the rotating plate can rotate at a certain angle with the horizontal bolt structure as the center.

[0015] Preferably, each of the protruding strips has a groove on its opposite side, and the groove is connected to the inner cavity of the slide. The groove design allows the rotating plate to move back and forth, meaning the horizontal bolt structure has movable space.

[0016] Preferably, the inner cavity of the slide is the same shape as the piston block, both being cylindrical structures, and a tension spring is installed in the inner cavity of the slide.

[0017] Preferably, the two ends of the tension spring abut against the inner wall of the slide and the end of the piston block, respectively.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 2. The clamping and fixing device for the installation parts of this refrigeration equipment, through the design and use of a rotating plate, a clamping plate, a piston block and a tension spring, can quickly reassemble and fix the grille. Compared with the bolt and nut fixing method of the existing technology, the assembly is simpler and more convenient, and does not require the cooperation of multiple people.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] This invention provides a technical solution for a clamping and fixing device for mounting parts of refrigeration equipment:

[0028] Example:

[0029] A clamping and fixing device for mounting parts of a refrigeration equipment includes a first fixing ring 1 and a second fixing ring 2. A fastening groove 4 is provided on one side of the first fixing ring 1, and an insertion ring 5 is provided on one side of the second fixing ring 2. Locking mechanisms are provided on the outer surfaces of both the first fixing ring 1 and the second fixing ring 2.

[0030] The locking mechanism mainly includes a protruding strip 6, a rotating plate 8, and a locking plate 9. The protruding strip 6 is fixedly installed on the outer side wall of the first fixing ring 1 and the second fixing ring 2. The rotating plate 8 is installed between the two protruding strips 6, and the locking plate 9 is fixedly installed at the end of the rotating plate 8.

[0031] In this design, annular grooves 3 are provided in the middle of the opposite sides of the first fixing ring 1 and the second fixing ring 2. The annular grooves 3 are fastened to the end face of the grille structure. Annular grooves of the same size as the annular grooves 3 are provided on the side of the clamping plate 9. When the clamping plate 9 is moved to a vertical position, the annular grooves on it can wrap around and fasten the ring structure of the grille on the other side.

[0032] Among them, a slide 11 is provided on one side of the protruding strip 6, and a piston block 7 is movably engaged in the inner cavity of the slide 11.

[0033] The piston block 7 has a horizontal bolt structure fixedly connected to each other on its opposite side, and holes adapted to the horizontal bolt structure are opened on both sides of the rotating plate 8. One end of the horizontal bolt structure is inserted into the hole on the side of the rotating plate 8, so that the rotating plate 8 can rotate at a certain angle with the horizontal bolt structure as the center.

[0034] Each of the protruding strips 6 has a groove on its opposite side, and the groove is connected to the inner cavity of the slide rail 11. The groove design allows the rotating plate 8 to move back and forth, meaning the horizontal bolt structure has movable space.

[0035] The inner cavity of the slide 11 has the same shape as the piston block 7, both being cylindrical structures, and a tension spring 10 is installed in the inner cavity of the slide 11.

[0036] The two ends of the tension spring 10 abut against the inner wall of the slide 11 and the end of the piston block 7, respectively.

[0037] In this embodiment, when using the clamping and fixing structure of this technical solution, especially when reinstalling the grille cover of the electric fan, the first fixing ring 1 is first fastened to the non-removable grille cover through the annular slot 3, and the second fixing ring 2 is fastened to the removed grille cover through the annular slot 3. Then, by aligning the insertion ring 5 with the fastening slot 4, the insertion ring 5 is directly inserted into the fastening slot 4 to complete the initial installation of the electric fan grille cover. No special position calibration is required in this process, and the installation is very convenient.

[0038] Then, directly move the rotating plate 8 to a position parallel to the outer ring of the grille cover. The retracted clamping plate 9 becomes vertical, and the annular groove on the clamping plate 9 covers and wraps the other side of the grille cover, thereby achieving rapid assembly and fixation of the grille cover.

[0039] It should be noted that when the rotating plate 8 is turned, the rotating plate 8 rotates around the horizontal bolt structure, and the rotating plate 8 needs to be pulled to move. When the rotating plate 8 moves, it will drive the piston block 7 to move along the inner cavity of the slide 11 through the horizontal bolt structure. When the piston block 7 moves, it will compress the tension spring 10 until the locking plate 9 is locked on the grille cover, and then the rotating plate 8 can be released.

[0040] When the rotating plate 8 is released, the tension spring 10 needs to return to its original position, which in turn pushes the piston block 7 in the opposite direction. The piston block 7 then applies a pulling force to the rotating plate 8, and finally applies a pulling force to the fan grille through the clamping plate 9, so that both grille covers tend to move closer to each other.

[0041] In this technical solution, the design and use of two fixing rings in conjunction with the annular slot 3, the fastening slot 4, and the plug-in ring 5 enable the rapid alignment and initial installation of the refrigeration equipment grille, which is more convenient and simpler than the existing plastic strip installation method.

[0042] Secondly, through the design and use of the rotating plate 8, the clamping plate 9, the piston block 7 and the tension spring 10, the reassembly and fixation of the grille can be achieved quickly. Compared with the bolt and nut fixing method of the existing technology, the assembly is simpler and more convenient, and does not require the cooperation of multiple people.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
