Description

Technical Field

[0001] This utility model relates to the field of laboratory equipment technology, and in particular to a high and low temperature circulation integrated machine with rapid cooling function. Background Technology

[0002] The high and low temperature cycle integrated machine is a laboratory equipment that has both heating and cooling functions. It is widely used in petroleum, chemical, metallurgical, pharmaceutical and biochemical fields. It can realize rapid high and low temperature cycle control within the same system, thereby providing a simulated environment for the property changes and thermal stress tests of various substances at specific temperatures.

[0003] A Chinese patent with publication number CN219252637U discloses a high and low temperature circulating integrated machine with rapid cooling function. The key technical points are: it includes a machine body, a fixed frame, and a first magnetic block. A groove is formed on one side of the machine body. Fixed blocks are fixedly connected to both ends of the fixed frame. The fixed blocks are connected to the groove by fasteners. The fixed frame has through slots distributed symmetrically, with a T-shaped cross-section. One side of the first magnetic block is fixedly connected to the side of the through slot away from the machine body. A fan blade device is provided within the through slot of the fixed frame. When the machine body generates a large amount of heat during operation, a drive motor drives a rotating shaft to rotate the fan blade device at high speed, thereby dissipating the heat generated inside the machine body and rapidly cooling it. This improves the stability of the machine body's operation and extends its service life.

[0004] Existing technologies often have the following drawbacks: when the high and low temperature circulation integrated machine with rapid cooling function is not used, the buttons on its control panel are exposed and are easily damaged by accidental touch or bumps.

[0005] Therefore, this utility model provides a high and low temperature circulation integrated machine with rapid cooling function. Utility Model Content

[0006] The purpose of this utility model is to solve the problem that in the existing technology, when a high and low temperature circulation integrated machine without a rapid cooling function is used, the buttons on its control panel are exposed and are easily damaged by accidental touch or bumps. Therefore, this utility model proposes a high and low temperature circulation integrated machine with a rapid cooling function.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a high and low temperature circulating integrated machine with rapid cooling function, comprising a casing, a heat dissipation box fixedly connected to the side of the casing, a control panel fixedly connected to the surface of the casing, two connection ports installed on the side of the casing away from the heat dissipation box, and a protective device provided on the side of the casing near the control panel. The protective device comprises two rectangular plates, both of which are fixedly connected to the side of the casing near the control panel, and a first protective plate and a second protective plate are rotatably connected to the side of the two rectangular plates away from the casing, respectively.

[0008] The effect achieved by the above components is that the first protective plate and the second protective plate can be connected to the casing through the rectangular plate, thereby shielding the control panel and protecting the buttons on the control panel.

[0009] Preferably, a clamping plate is fixedly connected to the side of the first protective plate away from the casing, and a fixing plate is fixedly connected to the side of the second protective plate away from the casing, with a sliding rod slidably connected to the inner wall of the fixing plate.

[0010] The effect achieved by the above components is that the first protective plate and the second protective plate can be easily connected and their positions restricted by the set clamping plate, fixing plate and sliding rod.

[0011] Preferably, an arc-shaped block is fixedly connected to one end of the slide bar near the card plate, and the side of the arc-shaped block near the machine housing is an arc surface.

[0012] The effect achieved by the above components is that, during the process of moving the arc-shaped block close to the plate, the arc surface of the arc-shaped block contacts the plate, thereby pushing the arc-shaped block to drive the slide rod to move.

[0013] Preferably, a pull plate is fixedly connected to the end of the slide rod away from the arc-shaped block, and a first spring is sleeved on the surface of the slide rod, with the two ends of the first spring being fixedly connected to the pull plate and the fixed plate, respectively.

[0014] The effect achieved by the above components is that the first spring can be installed through the set pull plate, thereby achieving the effect of limiting the position of the slide bar.

[0015] Preferably, a limiting device is provided on the side of the housing near the connection port. The limiting device includes four arc-shaped blocks, all of which are installed on the side of the housing near the connection port, and each of the four arc-shaped blocks is glued with a rubber pad on the side near the connection port.

[0016] The effect achieved by the above components is that after the connecting cable is connected to the housing through the connecting socket, the connecting cable can be clamped by the arc-shaped clip and rubber pad, thereby restricting its position and minimizing the risk of bending or breaking the connecting cable.

[0017] Preferably, four sleeve plates are fixedly connected to the side of the housing near the arc-shaped locking block, and sliding plates are slidably connected to the inner walls of the four sleeve plates. Adjusting screws are threaded into the inner walls of the sliding plates, and the adjusting screws are rotatably connected to the arc-shaped locking block.

[0018] The effect achieved by the above components is that the sliding plate and the sleeve plate ensure that the adjusting screw and the arc-shaped locking block can move, thereby providing a buffer effect for the connecting wires.

[0019] Preferably, each of the four arc-shaped blocks has two guide rods fixedly connected to the side of the slide plate, and the two guide rods are slidably connected to the inner wall of the slide plate. The side of the slide plate near the housing has two second springs fixedly connected, and the other ends of the two second springs are fixedly connected to the sleeve plate.

[0020] The aforementioned components achieve the following effects: the guide rod can restrict the rotation of the arc-shaped locking block, and the second spring can slow down the movement of the slide during its movement, thereby providing a buffering effect for the bending of the connecting line.

[0021] In summary:

[0022] 1. In this utility model, by setting up protective devices, when the high and low temperature cycle integrated machine with rapid cooling function is not in use, the control panel can be shielded by the first protective plate and the second protective plate, so as to avoid accidental touch or bumping of the buttons on the control panel as much as possible, thereby protecting the buttons on the control panel.

[0023] 2. In this utility model, the limiting device can clamp the connecting wire with the arc-shaped block and rubber pad after the wire is connected through the connector. At the same time, the sliding plate, the second spring and the sleeve plate can buffer the connecting wire when it tends to bend, thereby avoiding bending of the connecting wire as much as possible.

[0030] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a high and low temperature circulation integrated machine with rapid cooling function, including a housing 1, a heat dissipation box 3 fixedly connected to the side of the housing 1, a control panel 2 fixedly connected to the surface of the housing 1, two connection ports 4 installed on the side of the housing 1 away from the heat dissipation box 3, a protective device 5 provided on the side of the housing 1 close to the control panel 2, and a limiting device 6 provided on the side of the housing 1 close to the connection ports 4.

[0031] The specific design and function of its protective device 5 and limiting device 6 will be explained below.

[0032] Reference Figure 1 and Figure 2 as well as Figure 3 As shown in this embodiment, the protective device 5 includes two rectangular plates 51, both of which are fixedly connected to the side of the housing 1 near the control panel 2. A first protective plate 52 and a second protective plate 53 are rotatably connected to the sides of the two rectangular plates 51 away from the housing 1, respectively. Through the rectangular plates 51, the first protective plate 52 and the second protective plate 53 can be connected to the housing 1, thereby shielding the control panel 2 and protecting the buttons on the control panel 2. A retaining plate 54 is fixedly connected to the side of the first protective plate 52 away from the housing 1, and a fixing plate 55 is fixedly connected to the side of the second protective plate 53 away from the housing 1. A sliding rod 56 is slidably connected to the inner wall of the fixing plate 55. The retaining plate 54, the fixing plate 55, and the sliding rod 56 facilitate the connection and position restriction of the first protective plate 52 and the second protective plate 53.

[0033] An arc-shaped block 57 is fixedly connected to one end of the slide rod 56 near the clamping plate 54. The side of the arc-shaped block 57 closest to the housing 1 is curved. As the arc-shaped block 57 moves closer to the clamping plate 54, its curved surface contacts the clamping plate 54, thereby pushing the arc-shaped block 57 to move the slide rod 56. A pull plate 58 is fixedly connected to the end of the slide rod 56 away from the arc-shaped block 57. A first spring 59 is fitted onto the surface of the slide rod 56, and both ends of the first spring 59 are fixedly connected to the pull plate 58 and the fixing plate 55, respectively. The pull plate 58 allows the first spring 59 to be installed, thus restricting the position of the slide rod 56.

[0034] Reference Figure 2 and Figure 4 as well as Figure 5 As shown, specifically, the limiting device 6 includes four arc-shaped locking blocks 64, all of which are installed on the side of the housing 1 near the connection port 4. Each of the four arc-shaped locking blocks 64 near the connection port 4 has a rubber pad 65 glued to it. After the connecting wire is connected to the housing 1 through the connection port 4, the connecting wire can be clamped by the arc-shaped locking blocks 64 and the rubber pads 65, thereby limiting its position and minimizing the risk of bending or breaking. Four sleeve plates 61 are fixedly connected to the side of the housing 1 near the arc-shaped locking blocks 64. Slide plates 62 are slidably connected to the inner walls of each of the four sleeve plates 61. Adjusting screws 63 are threaded into the inner walls of the slide plates 62, and the adjusting screws 63 are rotatably connected to the arc-shaped locking blocks 64. The slide plates 62 and sleeve plates 61 ensure that the adjusting screws 63 and the arc-shaped locking blocks 64 can move, thus providing a buffering effect for the connecting wire.

[0035] Each of the four arc-shaped locking blocks 64 has two guide rods 66 fixedly connected to the side near the slide plate 62. Both guide rods 66 are slidably connected to the inner wall of the slide plate 62. Two second springs 67 are fixedly connected to the side of the slide plate 62 near the housing 1, and the other ends of both second springs 67 are fixedly connected to the sleeve plate 61. The guide rods 66 can restrict the rotation of the arc-shaped locking blocks 64, and the second springs 67 can slow down the movement of the slide plate 62 during movement, thus providing a buffer against bending of the connecting wires.

[0036] Working principle: When the high and low temperature circulation integrated machine with rapid cooling function is not used, the first protective plate 52 is first rotated close to the casing 1. At this time, the rectangular plate 51 restricts the rotation of the first protective plate 52. Then, the second protective plate 53 is rotated close to the first protective plate 52. During this process, the arc surface of the arc block 57 contacts the clamping plate 54, so that the arc block 57 pushes the slide rod 56 to slide on the inner wall of the fixed plate 55, causing the pull plate 58 to move away from the fixed plate 55. When the arc block 57 approaches the first protective plate 52, under the action of the elastic force of the first spring 59, the arc block 57 moves close to the clamping plate 54 and is inserted into the clamping plate 54, thereby completing the connection between the first protective plate 52 and the second protective plate 53, and at the same time restricting the position of the two. Through the heat dissipation box 3, the rapid cooling effect of the high and low temperature circulation integrated machine can be achieved. With the protective device 5 in place, when the high and low temperature cycle integrated machine with rapid cooling function is not in use, the control panel 2 can be shielded by the first protective plate 52 and the second protective plate 53, so as to avoid accidental touch or bumping of the buttons on the control panel 2 as much as possible, thereby protecting the buttons on the control panel 2.

[0037] After the connecting wire is connected to the housing 1 through the connecting socket 4, the adjusting screw 63 is rotated to make it rotate on the inner wall of the sliding plate 62 and the surface of the arc-shaped clamp 64. Under the guidance of the guide rod 66, the arc-shaped clamp 64 moves the rubber pad 65 closer to the connecting wire to clamp it. When the connecting wire tends to bend, it slides on the inner wall of the sleeve plate 61 through the arc-shaped clamp 64. When the external force on the connecting wire disappears, the sliding plate 62 moves away from the housing 1 under the elastic force of the second spring 67, so that the connecting wire returns to its original position. With the setting of the limiting device 6, after the wire is connected through the connecting socket 4, the arc-shaped clamp 64 and the rubber pad 65 can clamp the connecting wire. At the same time, the sliding plate 62, the second spring 67 and the sleeve plate 61 can buffer the connecting wire when it tends to bend, thereby avoiding bending of the connecting wire as much as possible.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
