Technical Field
[0001] This utility model relates to the field of fan processing technology, specifically a pressure-reducing device for processing labor-saving fans. Background Technology
[0002] A fan is a device used to generate airflow and cool down in hot weather. An electric fan is a device that uses electricity to generate airflow. When the fan inside is powered on, it rotates, converting mechanical energy into wind energy, which in turn creates a natural breeze to achieve a cooling effect. In the process of manufacturing fans, a labor-saving downward pressure device is needed.
[0003] Existing pressing devices introduce errors when placing parts, leading to inaccurate fan positioning and affecting fan operation. Furthermore, they suffer from several drawbacks: height adjustment is required, but current devices are often inconvenient, significantly reducing their versatility; fan stability is critical, but existing devices lack adequate fan limiting and anti-displacement capabilities, causing inaccurate fan machining due to displacement and reducing processing efficiency; and the spring force is critical, but current devices typically lack spring replacement protection, preventing spring detachment during manual pressing and making spring replacement inconvenient. Utility Model Content

[0007] Preferably, the surface of the device base is provided with a groove, the groove is connected to the interior of the fixed groove, the interior of the groove is provided with a limiting plate, and the inner wall of the device base is provided with a guide groove, the guide groove and the surface of the limiting plate slide in mutual engagement.
[0008] Preferably, each of the device bases is equipped with an electric push rod. The input end of the electric push rod is electrically connected to the output end of the control button. The output end of the electric push rod is fixed to the surface of the limiting plate. Each of the limiting plates is equipped with equally spaced extension springs. The surface of each extension spring is equipped with a positioning clamp for limiting the fan.
[0009] Preferably, the replaceable anti-detachment component is disposed on the surface of the L-shaped support frame. The replaceable anti-detachment component is composed of a groove, an arc-shaped slot, and an arc-shaped clip. The surface of the L-shaped support frame is fitted with an installation ring for blocking and limiting the spring body. The inner wall of the installation ring is provided with a groove.

[0010] Preferably, the surface of the L-shaped support frame is provided with an arc-shaped groove, the arc-shaped groove and the surface of the arc-shaped clip are engaged with each other, and the surface of the arc-shaped clip is provided with a telescopic spring, one end of the telescopic spring being fixed to the inner wall of the groove.

[0012] Preferably, the inner walls of the first arc-shaped frame and the second arc-shaped frame are provided with equally spaced roller grooves, and the surface of the roller groove is provided with rotating balls. The rotating balls rotate and cooperate with the inner wall of the roller groove, and the surface of the rotating balls is in contact with the surface of the support column.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the manual pressing device for fan processing not only allows the height of the fixed frame and fixed cylinder to be adjusted according to the pressing needs, greatly improving the versatility of the manual pressing device, but also allows the fan to be processed to be placed on the surface of the device base, avoiding the phenomenon of insufficient processing of the fan due to fan displacement during pressing, thus making the processing efficiency of the fan higher. Moreover, the manual pressing device can block the surface of the spring body during use, preventing the spring body from loosening during use, and making it more convenient to replace the spring body.
[0014] 1. By setting an adjustable height mechanism, the first arc-shaped frame and the second arc-shaped frame move on the surface of the support column. At this time, the rotating ball rotates on the surface of the groove. Under the combined action of the rotating ball and the groove, the spring body and the first arc-shaped frame move more quickly on the surface of the support column. At this time, the first arc-shaped frame drives the stabilizing suction cup inside the holding groove to move to contact the inner wall of the second arc-shaped frame. Under the combined action of the holding groove and the stabilizing suction cup, the second arc-shaped frame and the first arc-shaped frame are prevented from loosening. The first arc-shaped frame and the second arc-shaped frame are adjusted to the required height on the surface of the support column. Then, the screws on the surface of the first arc-shaped frame are tightened to install the first arc-shaped frame and the second arc-shaped frame on the surface of the support column. This realizes the function of adjusting the height of the manual pressing device. Thus, the height of the fixed frame and the fixed cylinder can be adjusted according to the pressing needs when using the manual pressing device, which greatly improves the versatility of the manual pressing device in use.
[0015] 2. By setting up a high-efficiency operating mechanism, the electric push rod inside the base of the control device works. Under the action of the electric push rod, the limiting plate slides inside the guide groove. Under the action of the guide groove, the limiting plate is guided. At this time, the limiting plate moves inside the groove. Under the elastic force of the extension spring on the surface of the limiting plate, the positioning clamp moves, so that the positioning clamp moves to contact the surface of the fan. Under the joint action of the limiting plate and the positioning clamp, the fan is clamped and limited inside the groove. This realizes the function of limiting and preventing displacement of the fan by the manual pressing device. Thus, when the manual pressing device is used, the fan to be processed can be placed on the surface of the device base. This avoids the phenomenon of insufficient precision in processing the fan due to fan displacement when the manual pressing device is pressing down, making the processing efficiency of the fan by the manual pressing device higher.
[0016] 3. By incorporating a replacement anti-detachment mechanism, the user places the installation ring onto the surface of the L-shaped support frame. The elastic force of the telescopic spring inside the groove drives the arc-shaped clip to move, causing it to engage with the arc-shaped slot. The engagement between the arc-shaped clip and the arc-shaped slot secures the installation ring to the surface of the L-shaped support frame. The installation ring acts as a barrier, preventing the spring from detaching from the L-shaped support frame during operation. This achieves the anti-detachment function of the manual pressing device for spring replacement, ensuring that the spring is prevented from loosening during use and making spring replacement more convenient.

[0025] The present invention provides a pressure-reducing device for manufacturing a labor-saving fan, the structure of which is as follows: Figure 1 and Figure 2 As shown, the device includes a base 1, a fixing plate 101 mounted on the surface of the base 1, a support column 102 mounted on the top of the fixing plate 101, a first arc-shaped frame 114 fitted onto the surface of the support column 102, and a second arc-shaped frame 115 fitted onto the surface of the support column 102. The second arc-shaped frame 115 is threadedly fastened to the surface of the first arc-shaped frame 114 by screws. A fixing frame 104 is mounted on the surface of the spring body 113, a moving rod 110 is provided on the top of the fixing frame 104, an L-shaped support frame 105 is mounted on the surface of the fixing frame 104, a connecting seat 116 is provided on the surface of the moving rod 110, and mounting screws 111 are threadedly connected to the surface of the moving rod 110. One end of the mounting screw 111 passes through the moving rod 110 and the connecting seat 116 and extends above the connecting seat 116. A fastening bolt 112 is threadedly fitted onto the surface of the mounting screw 111. The surface of the fixed frame 104 is in contact with the surface of the connecting seat 116. An operating handle 103 is provided on the surface of the fixed frame 104.

The model of the control button 117 can be selected from the LA series. A fixing cylinder 107 is installed on the surface at the bottom position of the frame body 109. A disassembly rod 108 is installed on the surface at the bottom position of the moving rod 110. One end of the disassembly rod 108 passes through the fixed frame 104 and the fixing cylinder 107 in sequence and extends to the bottom of the fixing cylinder 107. A fixing groove 106 is opened on the surface of the device base 1. The fixing groove 106 is located directly below the disassembly rod 108. A spring body 113 is fitted on the surface of the L-shaped support frame 105. The bottom end of the spring body 113 is fixed to the surface of the connecting seat 116.
[0026] Furthermore, such as Figure 2 and Figure 4As shown, each fixed groove 106 is equipped with a high-efficiency operating mechanism 2. The high-efficiency operating mechanism 2 includes an electric push rod 21, a guide groove 22, a limiting plate 23, a groove 24, a extension spring 25, and a positioning clamp 26. The surface of the device base 1 is provided with a groove 24, which is connected to the interior of the fixed groove 106. Each groove 24 is provided with a limiting plate 23. The inner wall of the device base 1 is provided with a guide groove 22, which slides with the surface of the limiting plate 23. Each device base 1 is equipped with an electric push rod 21, which can be of the DG series. The input end of the electric push rod 21 is electrically connected to the output end of the control button 117. The output end of the electric push rod 21 is fixed to the surface of the limiting plate 23. Each limiting plate 23 is equipped with an equally spaced extension spring 25, and the surface of the extension spring 25 is equipped with a positioning clamp 26 for limiting the fan.
[0027] During implementation, the electric push rod 21 inside the base 1 of the control device operates, and under the action of the electric push rod 21, the limiting plate 23 slides inside the guide groove 22. Under the action of the guide groove 22, the limiting plate 23 is guided. At this time, the limiting plate 23 moves inside the groove 24. Under the elastic force of the extension spring 25 on the surface of the limiting plate 23, the positioning clamp 26 moves, so that the positioning clamp 26 moves to contact the surface of the fan. Under the joint action of the limiting plate 23 and the positioning clamp 26, the fan is clamped and limited inside the groove 24, so as to realize the function of the manual pressing device to limit the fan and prevent displacement.
[0028] Furthermore, such as Figure 2 and Figure 5 As shown, the L-shaped support frame 105 is provided with a replaceable anti-detachment mechanism 3. The replaceable anti-detachment mechanism 3 includes an installation ring 31, a telescopic spring 32, and a replaceable anti-detachment component 33. The replaceable anti-detachment component 33 is provided on the surface of the L-shaped support frame 105 and is composed of a groove 331, an arc-shaped slot 332, and an arc-shaped clip 333. The surface of the L-shaped support frame 105 is fitted with an installation ring 31 for blocking and limiting the spring body 113. The inner wall of the installation ring 31 is provided with a groove 331. The inside of the groove 331 is provided with an arc-shaped clip 333. The arc-shaped clip 333 slides and engages with the inner wall of the groove 331. The surface of the L-shaped support frame 105 is provided with an arc-shaped slot 332. The arc-shaped slot 332 engages with the surface of the arc-shaped clip 333. The surface of the arc-shaped clip 333 is provided with a telescopic spring 32. One end of the telescopic spring 32 is fixed to the inner wall of the groove 331.
[0029] During implementation, the user places the mounting ring 31 onto the surface of the L-shaped support frame 105. Under the elastic force of the telescopic spring 32 inside the groove 331, the arc-shaped clip 333 moves, causing the arc-shaped clip 333 to engage with the inside of the arc-shaped slot 332. The engagement between the arc-shaped clip 333 and the arc-shaped slot 332 secures the mounting ring 31 onto the surface of the L-shaped support frame 105. The mounting ring 31 also acts as a barrier against the surface of the spring body 113, preventing the spring body 113 from detaching from the surface of the L-shaped support frame 105 during operation. This enables the manual pressing device to replace the spring body 113 without detaching.
[0030] Furthermore, such as Figure 3 and Figure 6 As shown, both the first arc-shaped frame 114 and the second arc-shaped frame 115 are equipped with height adjustment mechanisms 4 on their inner walls. The height adjustment mechanism 4 includes a stabilizing suction cup 41, a holding groove 42, and a height adjustment assembly 43. The height adjustment assembly 43 is located on the inner walls of both the first arc-shaped frame 114 and the second arc-shaped frame 115, and consists of rotating balls 431 and roller grooves 432. The inner wall of the first arc-shaped frame 114 is provided with a holding groove 42, and a useful... A stabilizing suction cup 41 is provided between the second arc-shaped frame 115 and the first arc-shaped frame 114 to prevent loosening. The surface of the stabilizing suction cup 41 is in contact with the inner wall of the second arc-shaped frame 115. The inner walls of the first arc-shaped frame 114 and the second arc-shaped frame 115 are provided with equally spaced roller grooves 432. The surface of the roller grooves 432 is provided with rotating balls 431. The rotating balls 431 rotate and cooperate with the inner wall of the roller grooves 432. The surface of the rotating balls 431 is in contact with the surface of the support column 102.
[0031] During implementation, the rotating ball 431 rotates on the surface of the groove 432. Under the combined action of the rotating ball 431 and the groove 432, the spring body 113 and the first arc-shaped frame 114 move more quickly on the surface of the support column 102. At this time, the first arc-shaped frame 114 drives the stabilizing suction cup 41 inside the holding groove 42 to move to contact the inner wall of the second arc-shaped frame 115. Under the combined action of the holding groove 42 and the stabilizing suction cup 41, the second arc-shaped frame 115 and the first arc-shaped frame 114 are prevented from loosening. The first arc-shaped frame 114 and the second arc-shaped frame 115 are adjusted to the required height on the surface of the support column 102. Then, the screws on the surface of the first arc-shaped frame 114 are tightened to install the first arc-shaped frame 114 and the second arc-shaped frame 115 on the surface of the support column 102 to realize the function of manually pressing down to adjust the height.
[0032] Working principle: In use, first place the device base 1 in the designated position. The user loosens the screws on the surface of the first arc-shaped frame 114, and then pulls the first arc-shaped frame 114 and the second arc-shaped frame 115 on the surface of the support column 102 respectively, so that the first arc-shaped frame 114 and the second arc-shaped frame 115 move on the surface of the support column 102. At this time, the rotating ball 431 rotates on the surface of the groove 432. Under the combined action of the rotating ball 431 and the groove 432, the spring body 113 and the first arc-shaped frame 114 move more quickly on the surface of the support column 102. At this time, the first arc-shaped frame 114 drives the stabilizing suction cup 41 inside the holding groove 42 to move to the second arc-shaped frame 114. The inner walls of the 5 are in contact. Under the combined action of the holding groove 42 and the stabilizing suction cup 41, the second arc-shaped frame 115 and the first arc-shaped frame 114 are prevented from loosening. The first arc-shaped frame 114 and the second arc-shaped frame 115 are adjusted to the required height on the surface of the support column 102. Then, the screws on the surface of the first arc-shaped frame 114 are tightened, and the first arc-shaped frame 114 and the second arc-shaped frame 115 are installed on the surface of the support column 102 to realize the function of adjusting the height of the manual pressing device. This allows the height of the fixed frame 104 and the fixed cylinder 107 to be adjusted according to the pressing needs when the manual pressing device is used, which greatly improves the versatility of the manual pressing device in use.
[0033] Subsequently, the user places the fan to be processed inside the groove 24 on the surface of the device base 1. The user operates the control button 117 on the surface of the frame 109, causing the control button 117 to control the electric push rod 21 inside the device base 1. Under the action of the electric push rod 21, the limiting plate 23 slides inside the guide groove 22. Under the action of the guide groove 22, the limiting plate 23 is guided. At this time, the limiting plate 23 moves inside the groove 24. Under the elastic force of the extension spring 25 on the surface of the limiting plate 23, the positioning clamp 26 moves, causing the positioning clamp 26 to move to contact the surface of the fan. Under the joint action of the limiting plate 23 and the positioning clamp 26, the fan is clamped and limited inside the groove 24, so as to realize the function of limiting and preventing displacement of the fan by the manual pressing device. This allows the fan to be processed to be placed on the surface of the device base 1 when the manual pressing device is used, avoiding the phenomenon of insufficient precision in the processing of the fan due to fan displacement during the pressing process. This makes the processing efficiency of the fan by the manual pressing device higher.
[0034] Subsequently, the user rotates the operating handle 103 on the surface of the fixing frame 104, causing the operating handle 103 to rotate inside the fixing frame 104. At this time, the user rotates the fastening bolt 112 on the surface of the mounting screw 111, and the fastening bolt 112 fixes the connecting seat 116 and the moving rod 110 together. Under the elastic force of the spring body 113 on the surface of the connecting seat 116, the moving rod 110 moves downward, causing the moving rod 110 to move the disassembly rod 108 to the outside of the fixing cylinder 107. At this time, the disassembly rod 108 removes the surface of the fixing cylinder 107. The disassembly rod 108 is pushed open, causing its bottom end to move to the center of the fan assembly and extend below it. At this time, one end of the disassembly rod 108 moves into the interior of the fixing groove 106. With the cooperation of the fixing cylinder 107 and the disassembly rod 108, the parts on the surface of the fan assembly are removed. Then, under the elastic force of the spring body 113, the disassembly rod 108 is automatically moved upward. At this time, the removed parts are left on the surface of the fixing cylinder 107 as the disassembly rod 108 moves. At this time, the user can remove the fan assembly from the surface of the device base 1 and then remove the parts from the surface of the fixing cylinder 107.
[0035] Subsequently, the user places the mounting ring 31 onto the surface of the L-shaped support frame 105. Under the elastic force of the telescopic spring 32 inside the groove 331, the arc-shaped clip 333 moves, causing the arc-shaped clip 333 to engage with the inside of the arc-shaped slot 332. The engagement between the arc-shaped clip 333 and the arc-shaped slot 332 secures the mounting ring 31 onto the surface of the L-shaped support frame 105. The mounting ring 31 acts as a barrier against the surface of the spring body 113, preventing the spring body 113 from detaching from the surface of the L-shaped support frame 105 during operation. This achieves the function of preventing the spring body 113 from detaching when the manual pressing device is used. This allows the manual pressing device to block the surface of the spring body 113 during use, preventing the spring body 113 from detaching during operation. This makes it more convenient to replace the spring body 113 using the manual pressing device, thus completing the use of the pressing device.
