Description

Technical Field

[0001] The present invention relates to the technical field of air heaters, and more particularly to an air source heat pump air heater and cooling machine assembly device. Background Art

[0002] In the modern air-conditioning and refrigeration industry, air source heat pump cooling and heating fans are widely used in various scenarios as an important temperature control device. Their core components include a circular outer shell and an internal fan. The installation accuracy of these components directly affects the operating efficiency and service life of the equipment. Especially during the installation of the fan, it is necessary to consider the precise positioning of both the axial distance and the circumferential angle. The adjustment of the axial position is related to the gap between the fan blades and the outer shell, which directly affects the stability of the airflow and noise control; while the adjustment of the circumferential angle involves the dynamic balance of the fan, which has an important impact on the vibration control and operating life of the equipment.

[0003] However, traditional installation methods often require repeated debugging to achieve the ideal installation effect, which not only increases the installation time, but also easily causes damage to components. Especially when adjusting the circumferential angle, due to the lack of precise positioning mechanism, installers often need to rely on experience to judge. This highly subjective adjustment method makes it difficult to ensure the accuracy of the installation. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the problems existing in the prior art, the present invention provides an air source heat pump cooling and heating fan assembly device to solve the technical problems mentioned in the background technology.

[0005] (II) Technical solution To achieve the above object, the present invention provides the following technical solutions: an air source heat pump cooling and heating fan assembly device, comprising three retractable rods and a fixing sleeve fixedly connected to the retractable rods; A follow-up mechanism, comprising a plurality of follow-up springs installed on the outer wall of the fixed sleeve at equal intervals, the plurality of follow-up springs are respectively connected to the fitting wheel, a plurality of pressure rods are respectively installed between the plurality of follow-up springs, a plurality of telescopic grooves are opened on the side wall of the fitting wheel at equal intervals, a telescopic rod is slidably connected in each of the telescopic grooves, a support spring is installed in the telescopic rod, a resistance disk is installed on the support spring on one side close to the fixed sleeve, and a stop block is installed on the support spring on the other side; and The rotating mechanism comprises a fixing frame installed on the external equipment, two outer sleeves are installed on the fixing frame, an inner sleeve is rotatably installed on each outer sleeve, and the two inner sleeves are respectively installed on both sides of the follower frame.

[0006] Preferably, multiple rollers are rotatably installed on the multiple fitting wheels at equal intervals, and when multiple pressure rods are respectively pressed on the contact disk, the stop block contacts the side wall of the roller. A return spring is respectively installed on each contact disk, and the return spring is connected to the inner wall of the fitting wheel. This design realizes the clamping of the outer shell through the rotating installation of the roller, and the cooperation of the pressure rod and the contact disk provides pressure control to ensure the limitation of the roller, and the setting of the return spring ensures that the stop disk can be automatically reset, forming a complete clamping-release cycle system.

[0007] Preferably, the rotating mechanism also includes a driven wheel rotatably connected to the inner sleeve, the driven wheel is rotatably connected to the retraction rod, a synchronization frame is rotatably mounted on the follower frame, and a synchronization plate is rotatably connected between the driven wheel and the synchronization frame. Through the coordinated work of the driven wheel, the synchronization frame and the synchronization plate, the synchronous movement of the retraction rod is achieved, thereby ensuring the uniform distribution of the clamping force and avoiding deformation or positioning deviation caused by uneven force.

[0008] Preferably, a driving shaft is rotatably connected to the inner sleeve, and two driving wheels are installed on both sides of the driving shaft, the driving wheel fits on the inner sleeve, and the driving wheel meshes with the driven wheel, a motor is installed on the inner sleeve, and the protruding end of the motor is connected to the driving shaft. This transmission structure drives the driving shaft through the motor, and then transmits the power through the meshing of the driving wheel and the driven wheel, thereby achieving smooth and controllable power output.

[0009] Preferably, handles are respectively installed on the two inner sleeves, and the two handles are on the same plane. The symmetrical design of the handles achieves convenient operation and ensures convenience of operation and observation during the adjustment process.

[0010] Preferably, the rotating mechanism also includes a plurality of positioning holes formed on the inner sleeve, a mounting sleeve is fixedly connected to the outer sleeve, a positioning rod is slidably connected to the mounting sleeve, and the positioning rod is clamped in the positioning hole. This positioning structure realizes angular positioning through the cooperation between the positioning rod and the positioning hole, thereby ensuring the stability of the position after adjustment.

[0011] Preferably, a plurality of expansion frames are slidably connected to the side wall of the mounting sleeve at equal intervals, an annular groove is provided on the side wall of the positioning rod, and the plurality of expansion frames are respectively inserted into the annular groove, and a push plate is installed on the positioning rod. Through the coordinated design of the expansion frame and the annular groove, the positioning rod is reliably locked, and the setting of the push plate facilitates the operator to make quick adjustments.

[0012] Preferably, two extension plates are respectively installed on both sides of each expansion frame, the upper limit sliding connection of the mounting sleeve is connected to the bottom sleeve, and the bottom sleeve is evenly spaced and provided with the same number of stop plates as the expansion frames.

[0013] Preferably, a push sleeve is slidably connected inside the installation sleeve, a plurality of limit springs are installed at equal intervals between the push sleeve and the bottom sleeve, and a plurality of the extension plates are located inside the limit springs. Through the combined design of the push sleeve, the limit springs and the extension plates, a flexible limit function is realized, thereby ensuring the reliability of fixation.

[0014] Preferably, a rotating disk is threadedly provided on the outer wall of the mounting sleeve, and a plurality of double clamping rods are evenly spacedly installed at the lower end of the rotating disk, and the plurality of double clamping rods are rotatably connected in the push sleeve respectively.

[0015] (III) Beneficial effects Compared with the prior art, the present invention provides an air source heat pump cooling and heating fan assembly device, which has the following beneficial effects: The axial position and circumferential angle can be adjusted through the motor-driven rotating mechanism and the coordinated retractable rod system. During axial adjustment, the self-locking function of the worm gear ensures the stability of the adjusted position, while the circumferential angle is adjusted through the rotation of the inner and outer sleeves. This design makes the adjustment process smoother and more precise, and improves installation efficiency.

[0016] By adopting an innovative multi-level fixing system, the precise locking of the angle position is achieved through the cooperation of the expansion frame, positioning rod and annular groove. At the same time, the design of the push sleeve and limit spring provides a reliable secondary fixing function to ensure stability during long-term use. This multiple protection mechanism effectively avoids the loosening problem that may occur during use.

[0017] Through the reasonable design of the handle and the coordination of the positioning system, the operator can complete the complex installation and adjustment process through simple turning and pushing and pulling movements, which improves work efficiency, especially when adjustments are required.

DETAILED DESCRIPTION

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0022] In the present invention, unless otherwise specified, the directions used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0023] See also Figures 1 to 7 , an air source heat pump cooling and heating fan assembly device, comprising three retractable rods 11 and a fixed sleeve 12 fixedly connected to the retractable rod 11, a follower mechanism comprising a plurality of follower springs 21 installed at equal intervals on the outer wall of the fixed sleeve 12, the plurality of follower springs 21 are respectively connected to a fitting wheel 22, a plurality of pressure rods 23 are respectively installed between the plurality of follower springs 21, a plurality of telescopic grooves 24 are opened at equal intervals on the side wall of the fitting wheel 22, and a telescopic rod 23 is slidably connected in each telescopic groove 24 5. A support spring 26 is installed in the telescopic rod 25, and a contact plate 27 is installed on the support spring 26 on the side close to the fixed sleeve 12, and a stop block 28 is installed on the support spring 26 on the other side. A plurality of rollers 29 are rotatably installed on the plurality of fitting wheels 22 at equal intervals. When the plurality of pressure rods 23 are respectively pressed on the contact plates 27, the stop blocks 28 contact the side walls of the rollers 29. A return spring 210 is respectively installed on each of the contact plates 27, and the return spring 210 is connected to the inner wall of the fitting wheel 22.

[0024] When fixing the housing and then connecting with the fan, first the positioning rod 314 and the positioning hole 312 are not in a connected state, and then the circular housing is placed between the two inner sleeves 33. Figure 3 , and then start the motor 310, and the driving wheel 39 is driven to rotate under the action of the motor 310, and the driving wheel 39 is meshed with the driven wheel 35, and the synchronous frame 36 can be synchronously driven to rotate through the synchronous plate 37. Since the retractable rods 11 are respectively connected to the driven wheel 35 and the synchronous frame 36, they will synchronously drive multiple retractable rods 11 to retract along the axis of the inner sleeve 33, so that the roller 29 fits on the side wall of the circular shell. Since the motor 310 and the driving shaft 38 are connected through the worm gear, there is a self-locking function. When the multiple rollers 29 are respectively fitted on the outer wall of the shell, and drive the shell to move in the direction of the axis and then move to coincide with the axis to stop the rotation of the motor 310, the follower spring 21 is only slightly deformed at this time, so the pressure rod 23 does not press on the contact plate 27, and the roller 29 can still rotate. Then the position of the shell on the axis can be adjusted, so that the shell is adjusted to the most suitable position for fan installation. Please refer to Figure 6 When the adjustment is completed, the motor 310 is started to make the multiple retracting rods 11 continue to retract toward the axis. At this time, since the roller 29 is attached to the side wall of the shell, the roller 29 will not move, so the follower spring 21 is compressed. Since multiple pressure rods 23 are installed, when the follower spring 21 moves a small distance, the pressure rod 23 presses on the abutment plate 27. Please refer to Figure 7Then the stop block 28 is pressed against the roller 29 so that the roller 29 is in a fixed state. With the continuous force, the compression amount of the support spring 26 can be increased to ensure the stability of the fixation. When the fixation is completed and needs to be released, the stop block 28 can be returned under the action of the return spring 210, ensuring the convenience of use.

A synchronous frame 36 is rotatably installed on the follower frame 34, and a synchronous plate 37 is rotatably connected between the driven wheel 35 and the synchronous frame 36. The driving shaft 38 is rotatably connected, and two driving wheels 39 are installed on both sides of the driving shaft 38, the driving wheel 39 is fitted on the inner sleeve 33, and the driving wheel 39 is meshed on the driven wheel 35, a motor 310 is installed on the inner sleeve 33, and the extended end of the motor 310 is connected to the driving shaft 38, and handles 311 are respectively installed on the two inner sleeves 33, and the two handles 311 are on the same plane, the rotating mechanism also includes a plurality of positioning holes 312 opened on the inner sleeve 33, and a mounting hole 312 is fixedly connected to the outer sleeve 32. The mounting sleeve 313 is slidably connected with a positioning rod 314 in the mounting sleeve 313, and the positioning rod 314 is stuck in the positioning hole 312. A plurality of expansion frames 315 are slidably connected with the side wall of the mounting sleeve 313 at equal intervals. An annular groove 316 is provided on the side wall of the positioning rod 314, and the plurality of expansion frames 315 are respectively inserted into the annular groove 316. A push plate 317 is installed on the positioning rod 314, and two extension plates 318 are respectively installed on both sides of each expansion frame 315. The upper limit of the mounting sleeve 313 is slidably connected with a bottom sleeve 31 9. The bottom sleeve 319 is provided with stop plates 320 of the same number as the expansion frame 315 at equal intervals. The mounting sleeve 313 is slidably connected with a push sleeve 321. A plurality of limit springs 322 are installed at equal intervals between the push sleeve 321 and the bottom sleeve 319, and a plurality of extending plates 318 are located inside the limit springs 322.

A plurality of double-clamp rods 324 are installed at equal intervals at the lower end of the rotating disk 323. The plurality of double-clamp rods 324 are rotatably connected in the pushing sleeve 321, respectively.

[0026] After the shell is adjusted on the axis, the circumferential angle needs to be adjusted. At this time, the positioning rod 314 and the positioning hole 312 are in a disengaged state. Figure 1 The operator holds the handle 311, and then drives the inner sleeve 33 to rotate along the outer sleeve 32, which drives the outer shell to rotate, so that the angle is adjusted and fixed. Please refer to Figure 8First, rotate the rotating disk 323. Since the rotating disk 323 and the mounting sleeve 313 are threadedly connected and the double clamping rod 324 is limitedly clamped on the push sleeve 321, the push sleeve 321 will be driven to move up and down. When the positioning rod 314 needs to be inserted into the positioning hole 312, the push sleeve 321 is moved to the position where the extension plate 318 is in the middle of the limit spring 322. Please refer to Fig. 9 When the fan 315 is in the state of being rotated, the rotation of the push sleeve 321 and the rotation of the push sleeve 321 is completed, and the rotation of the push sleeve 321 is completed.
