Description

Technical Field

[0001] The present invention relates to the technical field of controllers, and in particular to a control device for energy-saving refrigeration. Background Art

[0002] With the rapid development of modern industry and technology, various electronic devices and systems play an increasingly important role in people's daily life and industrial production. Among these devices and systems, refrigeration equipment is a key component to ensure its stable operation. Its performance and efficiency are directly related to the energy consumption and operating cost of the entire system. In most cases, existing controllers are fixed on the wall by bolts, which is not convenient for quick installation of controllers.

[0003] The patent with announcement number CN219995509U discloses an air-conditioning energy-saving controller based on a semiconductor refrigeration chip. When installing the controller component, first align the protection groove on the rear side of the controller component with the protection rod, and then push the controller component to the inside of the installation frame. At the same time, the limit block will be located on the inside of the limit hole, so that the position of the controller component can be initially limited. When the ring is pulled, the recovery rope can drive the clamping plate to move, and then the position movement of the clamping rod can be controlled, so as to realize the limiting and releasing functions of the limit block, so as to facilitate the position limitation of the controller component, and the limiting effect is better, so as to facilitate the disassembly and maintenance of the controller component.

[0004] Although the above scheme realizes the quick disassembly and assembly function of the controller assembly and improves the maintenance convenience of the equipment by designing the matching of the protection groove and the protection rod and the moving mechanism of the clip-on plate, but in the actual installation process, the above scheme requires a high matching accuracy between the protection groove and the protection rod on the controller assembly to ensure that the two are tightly connected to avoid gaps. When connecting the protection groove and the protection rod, the installer needs to carefully adjust the position of the controller assembly to ensure accurate connection. This operation not only increases the complexity of the installation, but also reduces the installation efficiency, because any slight position deviation may lead to poor matching, thereby affecting the stability and performance of the equipment.

[0017] 1.

DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] Reference Figures 1 to 12As shown: an energy-saving refrigeration control device, including a mounting plate 1 and a mounting frame 2 arranged on the front side of the mounting plate 1, and also including a controller structure 3, a clamping and positioning structure and two fixing structures 6; the controller structure 3 includes a controller component 31 and a connecting plate 32 arranged on the back side of the controller component 31, and a docking block 321 is arranged in the middle of the connecting plate 32; the clamping and positioning structure is arranged inside the mounting frame 2, and the clamping and positioning structure includes a first clamping structure 4 and a second clamping structure 5, and the first clamping structure 4 includes two L-shaped clamping plates 41 symmetrically arranged about the middle surface of the mounting frame 2, and the two ends of the L-shaped clamping plate 41 are fixed to the mounting frame 2. A first telescopic clamping assembly 42 is provided at each end, and the two first telescopic clamping assemblies 42 control the distance between the two L-shaped clamps 41. The second clamping structure 5 includes two first clamps 51 and two second telescopic clamping assemblies 52. The two first clamps 51 are symmetrically arranged in the middle of the two L-shaped clamps 41, and the first clamps 51 are perpendicular to the two side edges of the L-shaped clamps 41. The two second telescopic clamping assemblies 52 are arranged on the sides of the two L-shaped clamps 41, and the two second telescopic clamping assemblies 52 correspond to the two first clamps 51 respectively; the two fixing structures 6 are respectively arranged on the upper and lower sides of the mounting frame 2.

[0034] In the initial state, the clamping and positioning structure is located inside the installation frame 2, and is divided into a first clamping structure 4 and a second clamping structure 5. The two first telescopic clamping components 42 maintain that the distance between the two L-shaped clamping plates 41 is greater than the distance between the upper and lower surfaces of the docking block 321. The two second telescopic clamping components 52 respectively control the positions of the two first clamping plates 51 to ensure that the distance between the two first clamping plates 51 is greater than the distance between the left and right surfaces of the docking block 321. At this time, the two L-shaped clamping plates 41 and the two first clamping plates 51 together form a rectangular area, and the area is greater than the cross-sectional area of ​​the docking block 321. During installation, the docking block 321 is placed in the rectangular area, and then a force is applied to the controller component 31 toward the inside of the installation frame 2. The side of the docking block 321 and the L-shaped clamping plate 41 After contact, the L-shaped clamp 41 moves toward the inside of the installation frame 2, and at the same time, the two L-shaped clamps 41 gradually approach each other under the action of the two first telescopic clamping components 42 until the two side surfaces of the L-shaped clamp 41 are abutted against the two side surfaces of the docking block 321. At the same time, the two L-shaped clamps 41 apply force to the two second telescopic clamping components 52, so that the two first clamps 51 move toward each other under the drive of the two second telescopic clamping components 52 until the two first clamps 51 are pressed against the left and right side surfaces of the docking block 321, thereby achieving the clamping of the docking block 321. Finally, the connecting plate 32 is firmly connected to the installation frame 2 through the two fixing structures 6, thereby significantly reducing the docking accuracy requirements during the installation of the controller component 31, and achieving fast and stable installation of the controller component 31.

[0035] Reference Figure 4 and Figure 5As shown: the first telescopic clamping assembly 42 includes a first guide rod 421, two first sliders 422, two first connecting arms 423 and two first springs 424; the two ends of the first guide rod 421 are respectively connected to the upper and lower sides of the mounting frame 2; the two first sliders 422 are both slidably arranged on the first guide rod 421; the two first connecting arms 423 correspond to the two first sliders 422 respectively, and the two first connecting arms 423 are cross-arranged, and the two ends of the first connecting arms 423 are respectively axially connected to the first slider 422 and the L-shaped clamping plate 41; the two first springs 424 are respectively sleeved on the two ends of the first guide rod 421, and the two ends of the first spring 424 are respectively abutted against the ends of the first slider 422 and the first guide rod 421.

[0036] In the initial unstressed state, the two first springs 424 are in an unenergy-storing state, and the first slider 422 is close to the middle position of the first guide rod 421 due to the constraint of the natural length of the first spring 424, resulting in the angle between the two cross-arranged first connecting arms 423 remaining small, so that the two L-shaped clamping plates 41 and the two first clamping plates 51 together form a rectangular space at a position close to the opening of the installation frame 2. When the docking block 321 is placed in the rectangular space, the two L-shaped clamping plates 41 move toward the inside of the installation frame 2 due to the push of the docking block 321, and the movement of the two L-shaped clamping plates 41 is transmitted to the two first connecting arms 423 respectively. A slider 422 causes the two first sliders 422 to move apart to both sides along the first guide rod 421, and at the same time compresses the two first springs 424 to store elastic potential energy. As the two first sliders 422 move away from each other, the two first connecting arms 423 respectively pull the two L-shaped clamps 41 closer to each other, and in the process of the two L-shaped clamps 41 approaching each other, the two first clamps 51 approach each other to clamp the docking block 321. Since the clamping range surrounded by the two L-shaped clamps 41 and the two first clamps 51 is near the opening of the installation frame 2 when no force is applied, it is convenient for the installer to accurately place the docking block 321 within the clamping range, thereby improving the installation efficiency.

[0037] Reference Figure 4 and Figure 6 As shown: the first clamping structure 4 also includes a synchronous motion structure 43, which is arranged in the middle of the two L-shaped clamps 41, and the synchronous motion structure 43 includes a second guide rod 431 and two second sliders 432; the second guide rod 431 is vertically arranged in the middle of the L-shaped clamp 41; the two second sliders 432 are respectively fixedly connected to the two L-shaped clamps 41, and the two second sliders 432 are slidably connected to the two second guide rods 431.

[0038] The L-shaped clamping plate 41 is only constrained by the first connecting arm 423 and is connected to the first connecting arm 423 by an axial connection, so that the two surfaces of the two L-shaped clamping plates 41 that abut against the same surface on the docking block 321 are in a non-coplanar state. When the docking block 321 is placed in the clamping range jointly surrounded by the two L-shaped clamping plates 41 and the two first clamping plates 51, there is a situation where the docking block 321 may first contact one of the L-shaped clamping plates 41, resulting in the two L-shaped clamping plates 41 not being subjected to force at the same time. By setting the synchronous motion structure 43, when the two L-shaped clamping plates 41 are in a static state, the second guide rod 431 and the two first clamping plates 51 are in a non-coplanar state. The cooperation of the second slider 432 ensures that the two L-shaped clamps 41 are in a coplanar state, and when the two L-shaped clamps 41 start to move, the two L-shaped clamps 41 will drive their respective associated second sliders 432 to slide synchronously along the second guide rod 431, and the two second sliders 432 always maintain a sliding connection with the second guide rod 431, thereby ensuring that the two L-shaped clamps 41 can maintain a coplanar state during the entire movement process, ensuring that the docking block 321 can contact the two L-shaped clamps 41 at the same time, thereby achieving the two L-shaped clamps 41 simultaneously bearing the force from the docking block 321.

[0039] Reference Figure 5 and Figure 6 As shown: the synchronous motion structure 43 also includes two limiting structures 433, which are respectively arranged at the two ends of the second guide rod 431. The limiting structure 433 connects the end of the second guide rod 431 with the mounting frame 2. The limiting structure 433 includes a first telescopic arm 4331, a second telescopic arm 4332 and a second spring 4333. One end of the first telescopic arm 4331 is connected to the mounting frame 2, the second telescopic arm 4332 is coaxially arranged with the first telescopic arm 4331, and one end of the second telescopic arm 4332 is slidably connected to the second guide rod 431. The second spring 4333 is arranged inside the first telescopic arm 4331, and the two ends of the second spring 4333 are respectively connected to the end of the first telescopic arm 4331 and the end of the second telescopic arm 4332.

[0040] Since the second guide rod 431 needs to move with the two L-shaped clamping plates 41, it is necessary to limit the two ends of the second guide rod 431 so that the two ends of the second guide rod 431 can move synchronously to achieve the vertical translation of the second guide rod 431 and play the role of the two L-shaped clamping plates 41 being coplanar. By respectively providing limiting structures 433 at the two ends of the second guide rod 431, in the initial state, due to the pre-tightening force of the second spring 4333, the second telescopic arm 4332 coincides with the first telescopic arm 4331. When the second guide rod 431 moves toward the outside of the installation frame 2, the two ends of the second guide rod 431 will slide smoothly along the second telescopic arms 4332 in the two limiting structures 433. Once the second guide rod 431 moves to contact with the end of the second telescopic arm 4332, the second guide rod 431 will further The second telescopic arm 4332 is further pushed to move along the axis direction of the first telescopic arm 4331. During this process, the second spring 4333 is gradually stretched and stores elastic potential energy. On the contrary, when the second guide rod 431 is driven externally to move toward the inside of the installation frame 2, the elastic potential energy in the second spring 4333 is released, prompting the second spring 4333 to contract, keeping the end of the second telescopic arm 4332 in close contact with the second guide rod 431. Under this action, the second telescopic arm 4332 will move in the opposite direction along the axis direction of the first telescopic arm 4331, ensuring that the two ends of the second guide rod 431 can move synchronously and smoothly along the axes of the two first telescopic arms 4331 toward the inside of the installation frame 2, thereby ensuring that the two ends of the second guide rod 431 can maintain synchronous movement during the movement.

[0041] Reference Figure 7 and Figure 8 As shown: the second telescopic clamping assembly 52 includes a connecting block 521 and two second connecting arms 522; the connecting block 521 is arranged in the middle of the two L-shaped clamps 41, and the middle of the connecting block 521 is connected to the first clamp 51; the two second connecting arms 522 are respectively arranged at the upper and lower ends of the connecting block 521, and the two ends of the second connecting arm 522 are respectively axially connected to the end of the connecting block 521 and the end of the L-shaped clamp 41.

[0042] The two second connecting arms 522 in the second telescopic clamping assembly 52 form a V-shaped opening toward one end of the L-shaped clamping plate 41. When the two L-shaped clamping plates 41 move toward the outside of the installation frame 2, the two L-shaped clamping plates 41 will move away from each other. At this time, the two L-shaped clamping plates 41 respectively apply a force to the two second connecting arms 522 to move away from each other, and the two second connecting arms 522 are subjected to a force horizontally toward the ends of the L-shaped clamping plates 41, so that the connecting block 521 moves horizontally toward the ends of the L-shaped frame plates, and the distance between the two first clamping plates 51 increases. When the two L-shaped clamping plates 41 move toward the inside of the installation frame 2, the two L-shaped clamping plates 41 apply a force in opposite directions to the two second connecting arms 522, and the two second connecting arms 522 form a force horizontally toward the middle part of the L-shaped clamping plate 41 at the connecting block 521, so that the connecting block 521 moves toward the middle part of the L-shaped clamping plate 41, and the connecting block 521 drives the first clamping plate 51 to move, thereby realizing the linkage between the two first clamping plates 51 and the two L-shaped frame plates.

[0043] Reference Figure 7 and Figure 8 As shown: the second clamping structure 5 also includes a guiding structure 53, which is arranged between the two second telescopic clamping assemblies 52, and the guiding structure 53 is connected to the two connecting blocks 521 in the two second telescopic clamping assemblies 52, and the guiding structure 53 includes a third guide rod 531 and two third springs 532, the third guide rod 531 is horizontally arranged between the two L-shaped clamping plates 41, the two connecting blocks 521 are slidably connected to the third guide rod 531, and the two third springs 532 are respectively sleeved on both ends of the third guide rod 531, and the two ends of the third spring 532 are respectively abutted against the ends of the connecting block 521 and the third guide rod 531.

[0044] When the two second connecting arms 522 apply a force toward the end of the L-shaped clamping plate 41 to the connecting block 521, the connecting block 521 will move toward the corresponding end along the third guide rod 531. During this process, the third spring 532 between the connecting block 521 and the end of the third guide rod 531 is compressed. On the contrary, when the two second connecting arms 522 apply a force toward the middle of the L-shaped clamping plate 41 to the connecting block 521, the previously compressed third spring 532 will release its elastic potential energy, assisting the connecting block 521 to move toward the middle of the third guide rod 531. Since the two connecting blocks 521 slide along the third guide rod 531, it is ensured that the two first clamping plates 51 can be maintained at the same height. When the two first clamping plates 51 are used to clamp the docking block 321, the two first clamping plates 51 can apply two opposite and collinear forces to the docking block 321, thereby achieving a force balance on the left and right sides of the docking block 321.

[0045] Reference Figure 7 and Fig. 9As shown: the second clamping structure 5 also includes two centering structures 54, which are respectively arranged at the two ends of the guide structure 53, and the centering structure 54 connects the guide structure 53 with the two L-shaped clamping plates 41, and the centering structure 54 includes a fourth guide rod 541, two arc-shaped cover plates 542 and two support structures 543, the fourth guide rod 541 vertically passes through the third guide rod 531, and the fourth guide rod 541 is fixedly connected to the third guide rod 531, the two arc-shaped cover plates 542 are respectively covered at the two ends of the fourth guide rod 541, and the fourth guide rod 541 is fixedly connected to the third guide rod 531, and the two arc-shaped cover plates 542 are respectively covered at the two ends of the fourth guide rod 541, and the fourth guide rod 541 is fixedly connected to the third guide rod 531. The two ends of the guide rod 541 are slidably connected to the two L-shaped clamps 41, and the two support structures 543 are respectively arranged at the two ends of the fourth guide rod 541. The support structure 543 includes a first plate body 5431, a second plate body 5432 and a fourth spring 5433. The first plate body 5431 is connected to the fourth guide rod 541, the second plate body 5432 is connected to the arc cover plate 542, and the second plate body 5432 is parallel to the first plate body 5431, and the two ends of the fourth spring 5433 are respectively connected to the first plate body 5431 and the second plate body 5432.

[0046] When the two L-shaped clamps 41 move away from each other due to external force, the two L-shaped clamps 41 will slide and separate along the fourth guide rod 541. During this process, the two fourth springs 5433 at both ends of the fourth guide rod 541 will be gradually compressed. Since the two fourth springs 5433 respectively apply elastic forces to the two ends of the fourth guide rod 541 to move away from each other, it is ensured that the fourth guide rod 541 maintains force balance in the vertical direction, thereby preventing the fourth guide rod 541 from being displaced in the vertical direction. Therefore, the third guide rod 531 fixedly connected to the fourth guide rod 541 can maintain its horizontal height unchanged. Since the two first clamps 51 are slidably connected to the third guide rod 531, when the third guide rod 531 maintains a horizontal height unchanged, the two first clamps 51 can also maintain their height unchanged, ensuring that the two first clamps 51 are always in the middle position of the two L-shaped clamps 41, thereby effectively avoiding direct contact between the two L-shaped clamps 41 and the two first clamps 51.

[0047] Reference Figure 8 and Fig.10 As shown: the second clamping structure 5 also includes two buffer structures 55, the two buffer structures 55 are respectively connected to the two connecting blocks 521 in the two second telescopic clamping assemblies 52, and the buffer structure 55 is connected to the first clamping plate 51, the buffer structure 55 includes a support plate 551, a fifth guide rod 552 and a fifth spring 553, the middle part of the support plate 551 is connected to the connecting block 521, one end of the fifth guide rod 552 is connected to the first clamping plate 51, and the other end of the fifth guide rod 552 is slidably connected to the support plate 551, the fifth spring 553 is sleeved on the fifth guide rod 552, and the two ends of the fifth spring 553 are respectively abutted against the first clamping plate 51 and the support plate 551.

[0048] Due to the linkage relationship between the two first clamps 51 and the two L-shaped clamps 41, when the two first clamps 51 are in contact with the left and right ends of the docking block 321, the two L-shaped clamps 41 may not yet be in contact with the upper and lower sides of the docking block 321. Therefore, two buffer structures 55 are set to make up for this potential gap. As the docking of the two first clamps 51 with the left and right ends of the docking block 321 is completed, the two L-shaped clamps 41 continue to move toward the docking block 321. During this process, the two second telescopic clamping assemblies 52 respectively apply forces to the two support plates 551, resulting in relative sliding between the support plates 551 and the fifth guide rod 552. As the sliding progresses, the fifth spring 553 is gradually compressed, thereby achieving that during the process of the L-shaped clamps 41 and the docking block 321, the two second clamping telescopic assemblies still have room for movement.

[0049] Reference Figure 4 and Fig.11 As shown: four sequentially connected surfaces of the docking block 321 are provided with continuous annular grooves 3211, the surface where the L-shaped clamping plate 41 abuts against the docking block 321 is provided with a first clamping strip 411, and the surface where the first clamping plate 51 abuts against the docking block 321 is provided with a second clamping strip 511, and the first clamping strip 411 and the second clamping strip 511 cooperate with the annular grooves 3211.

[0050] When the two L-shaped clamps 41 and the two first clamps 51 are tightly attached to the docking block 321, the docking block 321 is subjected to a stable restraining force in the up-down and left-right directions. However, in the front-back direction, the docking block 321 may shake due to the lack of corresponding restraining force. Therefore, a first clamping strip 411 is provided on the L-shaped clamping plate 41, a second clamping strip 511 is provided on the first clamping plate 51, and a continuous annular clamping groove 3211 is provided on the docking block 321. When the plate 41 is pressed against the upper and lower sides of the docking block 321 respectively, the first clamping strip 411 on the L-shaped clamping plate 41 will be embedded in the annular clamping groove 3211. At the same time, when the two first clamping plates 51 are pressed against the left and right sides of the docking block 321, the second clamping strip 511 on the first clamping plate 51 will also be embedded in the annular clamping groove 3211, so that the first clamping strip 411 and the second clamping strip 511 are in contact with the groove wall of the annular clamping groove 3211, thereby effectively limiting the shaking of the docking block 321 in the front and rear directions.

[0051] Reference Figure 3 and Fig.12As shown: the fixing structure 6 includes a fixing block 61 and a locking structure 62; the fixing block 61 is connected to the connecting plate 32, and a plug hole is opened in the middle of the fixing block 61; the locking structure 62 is arranged on the installation frame 2, and the locking structure 62 fixes the connecting plate 32 to the installation frame 2, and the locking structure 62 includes a U-shaped plate 621, a locking rod 622, a sixth spring 623 and a toggle rod 624, the U-shaped plate 621 is connected to the inner wall of the installation frame 2, the locking rod 622 is slidably connected to the two ends of the U-shaped plate 621, the sixth spring 623 is sleeved on the locking rod 622, and the two ends of the sixth spring 623 are respectively connected to the end of the locking rod 622 and the end of the U-shaped plate 621, one end of the toggle rod 624 is connected to the locking rod 622, and the other end of the toggle rod 624 extends out of the installation frame 2.

[0052] During the installation process, the installer first pushes the controller structure 3 into the installation frame 2. At this time, the first springs 424 in the two first telescopic clamping assemblies 42 are in a compressed state, which has a tendency to push the L-shaped clamping plate 41 out of the installation frame 2, which may cause the clamping of the docking block 321 to loosen. For this purpose, two fixing structures 6 are set. Before pushing in the controller structure 3, the installer needs to apply a force on the locking rod 622 in the opposite axial direction of the locking rod 622 by using the toggle rod 624 to stretch the sixth spring 623. Sufficient space is left between the end of the U-shaped plate 621 to accommodate the fixing block 61. When the controller structure 3 is pushed into the installation frame 2, the fixing block 61 is exactly located between the end of the locking rod 622 and the end of the U-shaped plate 621. At this time, the force on the toggle rod 624 is removed, and the sixth spring 623 contracts, pushing the locking rod 622 to insert into the fixing block 61 and finally to the end of the U-shaped plate 621, fixing the position of the fixing block 61, thereby effectively preventing the controller structure 3 from being pushed out of the installation frame 2 by the first spring 424 in the first telescopic clamping assembly 42.
