Description

Technical Field

[0001] The utility model relates to the technical field of chiller equipment, and particularly relates to a convenient maintenance device for a chiller unit. Background Technique

[0002] In the utility model patent No. CN219454298U, which discloses a chiller unit convenient for maintenance, through the sliding connection structure between the bottom plate and the U-shaped frame, the function of moving the chiller unit body out of the U-shaped frame to expand the maintenance space is realized, and the problem of inconvenient maintenance is solved to a certain extent.

[0003] However, the fixing of the bottom plate of this chiller unit adopts the method of screwing the fixing bolts with the threaded holes and threaded grooves, which has obvious limitations in actual maintenance operations: when the chiller unit needs to be maintained, the staff needs to manually unscrew the fixing bolts first to pull the bottom plate out of the chiller unit body; after the maintenance is completed, the fixing bolts need to be screwed tightly again to fix the bottom plate. This bolt fixing method has cumbersome operation steps. Especially in the scenario where the chiller unit needs to be frequently maintained, it will additionally increase the operation time and labor intensity of the staff and reduce the maintenance efficiency. Therefore, a chiller unit maintenance device is needed that can optimize the fixing and unlocking method of the bottom plate and further improve the operation convenience while retaining the function of sliding out. Summary of the Invention

[0004] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments.

[0008] As a preferred scheme of a convenient maintenance device for a chiller according to the present invention, wherein: the upper end of the elastic member is hinged to the bottom of the foot pedal, and the lower end is hinged to the top of the fixing plate.

[0009] As a preferred scheme of a convenient maintenance device for a chiller according to the present invention, wherein: a horizontal chute aligning with the bottom plate is recessed and opened on the inner bottom of the front and rear side walls of the U-shaped frame. Rectangular frames are protrudingly arranged on the front and rear side walls of the bottom plate. The top view cross-section of the rectangular frame is in an inverted "mouth" shape. Rotating wheels are equidistantly rotatably arranged inside the rectangular frame. The lower surface of the rotating wheel is in rolling connection with the lower surface of the chute.

[0010] As a preferred scheme of a convenient maintenance device for a chiller according to the present invention, wherein: mounting blocks are symmetrically fixedly installed at the left and right of the bottom of the front and rear side walls of the U-shaped frame. There are four mounting blocks in total, and each mounting block is provided with a vertical mounting hole.

[0011] As a preferred scheme of a convenient maintenance device for a chiller according to the present invention, wherein: universal wheels are uniformly fixedly arranged at the bottom of the bottom plate and the side plate. The bottom surface of the wheel body of the universal wheel is coplanar with the lower surface of the U-shaped frame. A handle is fixedly installed on the right side wall of the side plate.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] Please see Figures 1-4 The diagram shown is a structural schematic of an embodiment of a convenient maintenance device for a chiller unit according to this utility model. Please refer to [link / reference]. Figures 1-4 This paper provides a detailed introduction to a convenient maintenance device for water chiller units.

[0022] Example 1 This solution discloses a convenient maintenance device for a chiller unit, mainly including a U-shaped frame 100, a mounting port 101, a rotating shaft 102, a mounting rod 103, a fixing block 104, an insert block 105, a foot pedal 106, a fixing plate 107, an elastic element 108, a base plate 200, a side plate 201, and an insertion hole 202. The U-shaped frame 100 has a U-shaped cross-section when viewed from above. The mounting port 101 is located in the lower middle part of its left side. The mounting rod 103 is rotatably mounted inside the mounting port 101 via the rotating shaft 102. The fixing block 104 is fixed to the right end of the mounting rod 103. A circular insert block 105 is located at the lower end of the fixing block 104. The foot pedal 106 is fixed to the left end of the mounting rod 103. The fixing plate 107 located below the foot pedal 106 is fixed to the lower middle part of the left side wall of the U-shaped frame 100. The bottom of the foot pedal 106 is connected to the fixing plate 107. The top is hinged with an elastic element 108; the bottom of the inner side of the C-shaped frame 100 is horizontally slidably set with a base plate 200, the chiller unit body is installed on the top of the base plate 200, and a side plate 201 is fixed at the end away from the C-shaped frame 100. An insertion hole 202 is opened on the left side of the top. The elastic element 108 pushes the foot plate 106 to insert the insertion block 105 into the insertion hole 202. The left edge of the upper surface of the base plate 200 is rounded.

[0023] Solution Analysis: The core innovation of this solution lies in the construction of a foot-driven linkage fixing structure. The "U"-shaped structure of the U-shaped frame 100 provides a stable sliding track for the base plate 200. The opening of the mounting port 101 precisely matches the rotation range of the mounting rod 103, ensuring that the mounting rod 103 rotates around the pivot 102 without jamming. The fixing block 104 connects the mounting rod 103 and the insertion block 105, allowing the rotation of the mounting rod 103 to be directly transmitted to the insertion block 105. The cooperation between the circular insertion block 105 and the insertion hole 202 ensures smooth insertion and disengagement. The positional relationship between the foot pedal 106 and the fixing plate 107 (the fixing plate 107 is below the foot pedal 106) provides installation space for the elastic element 108. The hinged connection of the elastic element 108 allows it to adapt to the rotation of the foot pedal 106, always maintaining a thrust on the foot pedal 106. The smooth design of the left edge of the upper surface of the base plate 200 is a key detail. When the base plate 200 is pushed into the U-shaped frame 100, the smooth edge can naturally lift the insert 105 upwards to avoid hard collision and realize the automatic insertion of the insert 105 when it slides along the surface of the base plate 200 to the insertion hole 202.

[0024] Technical Benefits: This solution completely changes the cumbersome traditional bolt-fixing method, replacing manual bolt tightening with foot-operated operation, significantly simplifying the fixing and unlocking process. Under normal conditions, the thrust of the elastic element 108 ensures that the insert 105 is stably inserted into the socket 202, guaranteeing the reliability of the base plate 200 and the chiller unit body and preventing shaking during equipment operation. For unlocking, simply pressing the foot pedal 106 disengages the insert 105 from the socket 202. The entire process requires no tools and can be quickly completed by a single person, effectively saving maintenance preparation time. This is especially significant in scenarios where chiller units require frequent maintenance, significantly reducing the workload of staff. Furthermore, the smooth design of the left edge of the base plate 200 makes installation more convenient. There is no need to deliberately align the insert 105 with the socket 202; simply pushing the base plate 200 achieves automatic fixing, improving operational smoothness and user experience.

[0025] Example 2 This solution discloses a convenient maintenance device for a water chiller unit, which mainly includes a foot pedal 106; the foot pedal 106 is fan-shaped and its surface is provided with anti-slip texture.

[0026] Solution Analysis: The fan-shaped design of the foot pedal 106 is based on ergonomic optimization. Compared with the traditional rectangular plate, the fan-shaped structure can better fit the foot's pedaling posture, increase the contact area between the foot and the foot pedal 106, distribute the pressure during pedaling, and reduce foot fatigue caused by prolonged operation or frequent pedaling. The anti-slip texture on the surface is designed for actual operating environments. In maintenance scenarios, workers may wear shoes with oil stains or wetness. The anti-slip texture can effectively increase the friction between the foot and the foot pedal 106, preventing slippage during pedaling and ensuring that the pedaling action is accurately transmitted to the mounting rod 103, guaranteeing the reliable disengagement of the insert 105.

[0027] Technical Benefits: The fan-shaped foot pedal 106 significantly improves the comfort of foot operation, making it easier for operators to apply force and reducing discomfort, especially suitable for scenarios requiring repeated pressing. The anti-slip texture greatly enhances operational safety, preventing operational errors caused by slipping and ensuring the stability and reliability of the unlocking process. The combination of these two features makes foot operation both comfortable and safe, further optimizing the user experience and indirectly improving maintenance efficiency.

[0028] Example 3 This solution discloses a convenient maintenance device for a chiller unit, which mainly includes a mounting rod 103 and a rotating shaft 102; the length of the mounting rod 103 on the left side of the rotating shaft 102 is greater than the length of the mounting rod 103 on the right side of the rotating shaft 102.

[0029] Solution Analysis: The mounting rod 103, with the pivot 102 as its fulcrum, forms a force-saving lever structure. According to the lever principle, the longer the lever arm, the smaller the force required. The left side (the side connecting the foot pedal 106) of the mounting rod 103 is longer than the right side (the side connecting the fixing block 104 and the insertion block 105). This means that the operator can apply a smaller force to the foot pedal 106 to generate sufficient torque on the right side, causing the insertion block 105 to overcome the thrust of the elastic element 108 and disengage from the insertion hole 202. This length ratio design is precisely calculated, ensuring both force-saving effect and avoiding the wobbling of the mounting rod 103 due to an excessively long left side or the insufficient travel of the insertion block 105 due to an excessively short right side.

[0030] Technical benefits: This lever structure significantly reduces the force required for unlocking, allowing operators to perform the pressing action without applying excessive force. It is particularly suitable for workers with limited physical strength or for scenarios involving frequent, prolonged operation. This labor-saving design not only reduces operator fatigue but also improves the response speed of the unlocking action, enabling the insertion block 105 to quickly disengage from the insertion hole 202, further shortening maintenance preparation time and reflecting the equipment's user-friendly design philosophy.

[0031] Example 4 This solution discloses a convenient maintenance device for a chiller unit, which mainly includes an elastic element 108, a foot pedal 106, and a fixed plate 107; the upper end of the elastic element 108 is hinged to the bottom of the foot pedal 106, and the lower end is hinged to the top of the fixed plate 107.

[0032] Solution Analysis: The two ends of the elastic element 108 are hinged rather than fixed, allowing for adaptive angle adjustment as the foot pedal 106 rotates. When the foot pedal 106 is pressed down and rotates downwards, the elastic element 108 bends and deforms with the angle change of the foot pedal 106, storing elastic potential energy. When the foot pedal 106 is released, the elastic element 108 releases its potential energy, pushing the foot pedal 106 to rotate upwards and reset, simultaneously driving the insert 105 into the socket 202 via the mounting rod 103. The hinged connection ensures that the elastic element 108 is not subjected to additional torque or shear force during deformation, extending its service life, while ensuring that the thrust direction always matches the rotation trajectory of the foot pedal 106, maintaining stable thrust output.

[0033] Technical benefits: The hinged structure allows the force of the elastic element 108 to be transmitted to the footplate 106 more efficiently, ensuring that the insertion block 105 can be stably inserted into the insertion hole 202 under normal conditions, thus improving the fixing reliability of the base plate 200. At the same time, the deformation and reset process of the elastic element 108 is smoother, avoiding problems such as jamming or insufficient thrust caused by improper connection. This design extends the service life of the elastic element 108, reduces the frequency of equipment maintenance, lowers operating costs, and ensures the consistency and stability of fixing and unlocking actions.

[0034] Example 5 This solution discloses a convenient maintenance device for a chiller unit, mainly including a U-shaped frame 100, a sliding groove 109, a base plate 200, a rectangular frame 203, and rotating wheels 204; the inner bottom of the U-shaped frame 100 is recessed and has a transverse sliding groove 109 aligned with the base plate 200; the front and rear side walls of the base plate 200 are provided with a rectangular frame 203 protruding from the bottom; the top view cross-section of the rectangular frame 203 is inverted "U" shape; rotating wheels 204 are rotatably arranged at equal intervals on the inner side of the rectangular frame 203; the lower surface of the rotating wheels 204 is in rolling connection with the lower surface of the groove 109.

[0035] Solution Analysis: The slide groove 109 provides precise guidance for the sliding of the base plate 200, ensuring that the base plate 200 can only move laterally and avoids deviation. The rectangular frames 203 on the front and rear side walls of the base plate 200 are inverted "U" shapes, and the rotating wheels 204 arranged at equal intervals on their inner sides form a rolling support structure. The rolling contact between the rotating wheels 204 and the slide groove 109 converts the sliding friction between the base plate 200 and the U-shaped frame 100 into rolling friction, significantly reducing the coefficient of friction. The rectangular frames 203 not only provide a mounting carrier for the rotating wheels 204, but also protect the rotating wheels 204, preventing external dust and debris from entering and affecting the normal operation of the rotating wheels 204, while also enhancing the structural strength of the edges of the base plate 200.

[0036] Technical benefits: The application of rolling friction significantly reduces the sliding resistance of the base plate 200 within the U-shaped frame 100. Operators only need a small force to pull or push the base plate 200, making the movement of the chiller unit body easier and smoother. The guiding function of the slide groove 109 ensures the precise movement trajectory of the base plate 200, avoiding misalignment between the insertion block 105 and the insertion hole 202 due to misalignment. The protection of the rotating wheel 204 by the rectangular frame 203 extends the service life of the rolling structure, reduces the probability of equipment failure, and ensures the continuity and efficiency of the maintenance process.

[0037] Example 6 This solution discloses a convenient maintenance device for a chiller unit, which mainly includes a U-shaped frame 100, mounting blocks 110, and mounting holes 111; mounting blocks 110 are symmetrically fixedly installed on the bottom of the front and rear side walls of the U-shaped frame 100, and the mounting blocks 110 are provided with four in total, each with a vertical mounting hole 111.

[0038] Solution Analysis: Four mounting blocks 110 are symmetrically distributed on the bottom of the front and rear side walls of the U-shaped frame 100. This symmetrical structure allows the fixing force to be evenly distributed to all corners of the U-shaped frame 100, avoiding deformation of the U-shaped frame 100 due to excessive local stress. The mounting holes 111 are vertically opened, allowing bolts and other fasteners to pass through, facilitating a secure connection between the mounting blocks 110 and the ground or mounting foundation. The mounting blocks 110 are made of high-strength metal, ensuring they can withstand the overall weight of the U-shaped frame 100 and the chiller unit, while resisting the vibration and impact forces generated during equipment operation.

[0039] Technical benefits: By cooperating with the mounting block 110 and the mounting hole 111, the U-shaped frame 100 can be stably fixed to the ground, effectively preventing displacement or shaking of the equipment during operation or maintenance, and ensuring the operational stability of the chiller unit. The symmetrically distributed four mounting blocks 110 make the fixation more reliable, maintaining the positional accuracy of the U-shaped frame 100 even after long-term use or under external impact, avoiding problems such as poor sliding of the base plate 200 or misalignment of the insertion block 105 and the insertion hole 202 caused by the offset of the U-shaped frame 100, thus improving the overall safety and service life of the equipment.

[0040] Example 7 This solution discloses a convenient maintenance device for a chiller unit, mainly including a base plate 200, a side plate 201, casters 205, a U-shaped frame 100, and a handle 206; casters 205 are evenly fixedly arranged on the bottom of the base plate 200 and the side plate 201, and the bottom surface of the caster 205 is coplanar with the lower surface of the U-shaped frame 100; a handle 206 is fixedly installed on the right side wall of the side plate 201.

[0041] Solution Analysis: The casters 205 are evenly distributed at the bottom of the base plate 200 and side plate 201, providing stable support for the base plate 200 and the chiller unit body when the U-shaped frame 100 is pulled out, preventing the base plate 200 from tilting due to one end being suspended. The bottom of the casters 205 is coplanar with the lower surface of the U-shaped frame 100, ensuring that when the base plate 200 is inside the U-shaped frame 100, the casters 205 are in contact with the ground but do not bear additional pressure, thus ensuring the horizontal placement of the base plate 200 and preventing wear and tear on the casters 205 due to long-term stress. The handle 206 is fixed to the right side wall of the side plate 201, and its height is adapted to the hand position when the operator is standing, making it easy for the operator to apply pulling force to pull the base plate 200. The surface of the handle 206 is usually provided with anti-slip texture to further improve grip stability.

[0042] Technical Benefits: The casters 205 allow the base plate 200 to move flexibly after being pulled out of the U-shaped frame 100, facilitating the adjustment of the chiller unit to the most suitable maintenance position and breaking the limitations of fixed space on maintenance operations. The coplanar design ensures the stability of the base plate 200 within the U-shaped frame 100, preventing shaking during equipment operation. The handle 206 provides operators with a convenient point of leverage, and together with the rolling action of the rotating wheels 204, makes pulling out and pushing in the base plate 200 easier, significantly improving the operational flexibility and convenience during maintenance and reducing the physical exertion of personnel.

[0043] Working Principle: This solution primarily utilizes a linkage structure and mechanical coordination to facilitate convenient maintenance of the chiller unit. Under normal conditions, the elastic element 108 applies an upward thrust to the foot pedal 106, causing the mounting rod 103 to rotate clockwise around the shaft 102. This rotates the fixing block 104 and the insert block 105 downwards, allowing the insert block 105 to insert into the socket 202 of the base plate 200, thus securing the base plate 200 to the chiller unit body. When maintenance is required, the operator presses the foot pedal 106, causing it to rotate downwards and compress the elastic element 108. The mounting rod 103 rotates counterclockwise around the shaft 102, causing the insert block 105 to disengage upwards from the socket 202, thus unlocking the unit. At this time, the operator pulls the handle 206 on the side plate 201, causing the base plate 200 to slide along the groove 109 inside the C-shaped frame 100. The rotating wheels 204 inside the rectangular frames 203 on the front and rear side walls of the base plate 200 roll in contact with the groove 109, reducing sliding resistance. After the base plate 200 is pulled out of the C-shaped frame 100, the universal wheels 205 at its bottom contact the ground, supporting the base plate 200 and allowing it to move flexibly for easy maintenance. After maintenance is completed, the base plate 200 is pushed back into place, and the smooth part on the left edge of the upper surface of the base plate 200 will naturally lift the insert 105. When the base plate 200 is fully reset, the insertion hole 202 aligns with the insert 105, the elastic element 108 pushes the foot pedal 106 to reset, and the insert 105 is reinserted into the insertion hole 202, completing the fixation. In addition, the C-shaped frame 100 is fixed to the foundation by the mounting block 110 at the bottom and the mounting hole 111, ensuring overall stability.

[0044] Technical Benefits of Implementing this Solution: Implementing this solution will bring significant technical benefits in several aspects. In terms of ease of operation, foot-operated unlocking and fixing replaces traditional bolt operations. No tools are required, and a single person can complete unlocking or fixing within seconds, significantly shortening maintenance preparation time, especially suitable for scenarios requiring frequent maintenance of chiller units. Regarding labor saving and safety, the lever structure of the mounting rod 103 makes pressing the foot pedal 106 less strenuous. The fan-shaped design and anti-slip texture of the foot pedal 106 improves comfort and safety, avoiding the risk of slipping. In terms of stability and reliability, the hinged connection of the elastic element 108 ensures the stable insertion of the insertion block 105 into the insertion hole 202, and the symmetrical fixing of the four mounting blocks 110 prevents the U-shaped frame 100 from shaking, ensuring stable equipment operation. In terms of mobility and flexibility, the cooperation between the rotating wheel 204 and the slide groove 109 allows the base plate 200 to slide smoothly, the caster wheel 205 allows the base plate 200 to move flexibly after being pulled out, and the handle 206 provides a convenient point of force application, significantly reducing the physical exertion of operators. In addition, the structural design of each component (such as the rectangular frame 203 protecting the rotating wheel 204 and the rounded edges of the base plate 200 for easy return to its original position) extends the service life of the equipment, reduces the probability of failure, and comprehensively improves the efficiency and experience of chiller unit maintenance.

[0045] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
