Description

Technical Field

[0001] This utility model belongs to the technical field of temperature control equipment, specifically, it relates to a high and low temperature cycle integrated machine. Background Technology

[0002] In pilot-scale and kilogram-level laboratory settings, the high and low temperature circulation integrated machine has become an indispensable key device due to its ability to precisely control the temperature of the reactor. It is connected to the reactor through a liquid inlet pipe to achieve liquid circulation to regulate the temperature. Therefore, the stability, convenience, and related protection measures of the connection between the liquid inlet pipe and the inlet and outlet pipes of the integrated machine are crucial to the efficient and safe operation of the equipment.

[0003] For example, the utility model patent with patent application number 202321757407.X, entitled "Protection Device for High and Low Temperature Cycling Integrated Machine," although it limits and protects the delivery pipe by setting a protective shell and a movable clamping part, still has the following defects in practical applications:

[0004] ① In terms of connection efficiency, the double-layer clamping ring structure of its movable clamping part needs to overcome the pressure of the elastic movable part when the delivery pipe is inserted, and it lacks the design for quick positioning and initial connection. The installation process is relatively cumbersome and it is difficult to achieve quick connection without complicated tools, resulting in low installation efficiency.

[0005] ② Regarding connection stability, relying solely on the clamping force of the compression spring on the delivery pipe to prevent dislocation is easily affected when the equipment vibrates, making it difficult to guarantee a long-term stable locking state. Loosening may still occur at the connection between the delivery pipe and the inlet / outlet, posing a safety hazard.

[0006] ③ In terms of operational flexibility, when disassembling the conveying pipe, this structure needs to overcome the elastic force of the elastic moving part, and there is no convenient control component similar to a pull rod. The switching between locking and unlocking is not fast and flexible enough, which brings inconvenience to frequent installation and disassembly operations. In view of this, this utility model is proposed. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a high and low temperature cycle integrated machine that can overcome or at least partially solve the above problems.

[0008] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0009] A high and low temperature circulation integrated machine includes a main body, on which an inlet / outlet pipe for liquid entry and exit in a reaction vessel is provided on the side wall. The inlet / outlet pipe is connected to the reaction vessel via a delivery pipe. The machine also includes: a mounting cap, fixedly connected to the end of the delivery pipe away from the reaction vessel; a fixing ring, fixedly connected to the inlet / outlet pipe, wherein the fixing ring has a insertion groove, and the mounting cap has a corresponding insertion block fixedly connected to it. The insertion block has a snap-fit ​​groove. When the insertion block is inserted into the insertion groove, the mounting cap is rotated so that the insertion block intersects with the insertion groove of the fixing ring via the snap-fit ​​groove; and a locking component, disposed on the mounting cap and connected to the fixing ring, for locking and limiting the mounting cap.

[0010] Preferably, the locking component includes a locking pin, a pull rod, an elastic reset member, and a locking hole. A sliding groove is provided inside the mounting cap, the locking pin is slidably connected in the sliding groove, the locking hole is opened on the fixing ring, the elastic reset member is disposed in the sliding groove and is used to push the locking pin into the locking hole, the pull rod is fixedly connected to the locking pin, and one end away from the locking pin extends out of the sliding groove.

[0011] Furthermore, the elastic reset member includes a spring, which is disposed in the slide groove. One end of the spring is fixedly connected to the locking pin, and the other end is fixedly connected to the inner wall of the slide groove.

[0012] Furthermore, it also includes a handle, which is fixedly connected to the end of the lever away from the locking pin.

[0013] To increase friction and make it easier for operators to operate the handle, the handle is further provided with anti-slip textures, the textures of which are distributed in an interlaced diamond grid pattern.

[0014] To increase the sealing performance at the connection between the mounting cap and the inlet / outlet pipe, preferably, a sealing gasket is provided inside the mounting cap, and the sealing gasket fits snugly against the inlet / outlet pipe.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0016] This utility model, with its plug-in block and plug-in slot plug-in mating and rotating staggered structure, can quickly achieve the initial connection between the infusion tube and the inlet / outlet tube without complicated tools, greatly improving installation efficiency;

[0017] In the locking components, the elasticity and restoring properties of the spring ensure that the locking pin always tends to insert into the locking hole, guaranteeing a stable locking state, effectively preventing the mounting cap from accidentally rotating and loosening due to equipment vibration, enhancing the overall connection reliability, and reducing the risk of equipment failure.

[0018] The lever allows for easy control of the locking pin's movement, enabling quick switching between locking and unlocking, further enhancing operational flexibility. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0027] Example 1:

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6The high and low temperature circulation integrated machine includes a main body 1, with an inlet / outlet pipe 101 on the side wall for the liquid to enter and exit the reactor. The inlet / outlet pipe 101 is connected to the reactor through a delivery pipe 102. It also includes: a mounting cap 2, fixedly connected to the end of the delivery pipe 102 away from the reactor; a fixing ring 201, fixedly connected to the inlet / outlet pipe 101, wherein the fixing ring 201 has a insertion groove 202, and the mounting cap 2 has a corresponding insertion block 203 fixedly connected to the insertion groove 202. The insertion block 203 has a snap-fit ​​groove 204. When the insertion block 203 is inserted into the insertion groove 202, the mounting cap 2 is rotated so that the insertion block 203 intersects with the insertion groove 202 of the fixing ring 201 through the snap-fit ​​groove 204; and a locking component, provided on the mounting cap 2 and connected to the fixing ring 201, for locking and limiting the mounting cap 2.

[0029] The locking component includes a locking pin 301, a pull rod 304, an elastic reset member, and a locking hole 302. A sliding groove 3 is provided inside the mounting cap 2. The locking pin 301 is slidably connected in the sliding groove 3. The locking hole 302 is provided on the fixing ring 201. The elastic reset member is provided in the sliding groove 3 and is used to push the locking pin 301 into the locking hole 302. The pull rod 304 is fixedly connected to the locking pin 301, and one end away from the locking pin 301 extends out of the sliding groove 3.

[0030] The elastic reset component includes a spring 303, which is disposed in the slide groove 3. One end of the spring 303 is fixedly connected to the locking pin 301, and the other end is fixedly connected to the inner wall of the slide groove 3.

[0031] When connecting the infusion tube 102 and the inlet / outlet tube 101, first align the plug 203 on the mounting cap 2 with the plug groove 202 on the fixing ring 201 and insert it. Then rotate the mounting cap 2 so that the plug 203 intersects with the plug groove 202 of the fixing ring 201 through the snap-fit ​​groove 204 to achieve a stable snap-fit. When the mounting cap 2 is rotated to the appropriate position, the locking pin 301 in the locking component automatically slides from the slide groove 3 into the locking hole 302 on the fixing ring 201 under the elastic force of the spring 303, thus completing the locking and limiting of the mounting cap 2.

[0032] When disassembly is required, the operator pulls the lever 304, which causes the locking pin 301 to compress the spring 303, disengaging the locking pin 301 from the locking hole 302 and releasing the lock. Then, the mounting cap 2 is rotated in the opposite direction to align the insertion block 203 with the insertion slot 202. At this point, the compression of the sealing gasket 4 gradually dissipates. Finally, the insertion block 203 is pulled out of the insertion slot 202, completing the disassembly.

[0033] Through the insertion and engagement of the plug-in block 203 and the plug-in slot 202, and the staggered structure formed after rotation, the initial connection between the infusion tube 102 and the inlet / outlet tube 101 can be quickly achieved. This structure requires no complicated tools, is easy to operate, and greatly improves installation efficiency. In the locking component, the spring 303 has good elasticity and reset performance. Its elasticity makes the locking pin 301 always tend to insert into the locking hole 302, ensuring the stability of the locking state and effectively preventing the installation cap 2 from accidentally rotating and loosening due to vibration or other reasons during the operation of the integrated machine. This enhances the reliability of the overall connection and reduces the risk of equipment failure. At the same time, the pull rod 304 can be used to easily control the movement of the locking pin 301, realizing quick switching between locking and unlocking, further improving the flexibility of operation.

[0034] Example 2:

[0035] Reference Figure 6 The high and low temperature cycle integrated machine is basically the same as that in Example 1. Furthermore, it also includes a handle 305, which is fixedly connected to the end of the pull rod 304 away from the locking pin 301.

[0036] When the lever 304 needs to be pulled, the operator holds the handle 305 and pulls it, making it easier to apply force and allowing the locking pin 301 to smoothly exit from the locking hole 302. When the handle 305 is released, the elastic potential energy released by the compressed spring 303 can push the locking pin 301 to automatically reset. The handle 305 increases the contact area between the operator and the lever 304, so that when the same force is applied, the pressure on the operator's hand is reduced, making the operation more comfortable. It is also easier to control the magnitude and direction of the pulling force, improving the convenience and accuracy of the operation. Especially when performing frequent installation and disassembly operations, the handle 305 can effectively reduce the operator's hand fatigue and improve work efficiency.

[0037] The handle 305 is provided with anti-slip texture, and the texture is distributed in an interlaced diamond grid pattern;

[0038] When the operator holds the handle 305 with its diamond-patterned anti-slip texture to pull or release, the interlaced diamond-patterned anti-slip texture significantly increases the friction between the handle 305 and the operator's hand. Even if the hands are sweaty or oily, it can effectively prevent slippage and ensure that the operator can hold the handle 305 stably during operation, thus improving operational safety. At the same time, this texture design not only has a good anti-slip effect but also has a certain aesthetic appeal.

[0039] Example 3:

[0040] Reference Figure 2 , Figure 5The high and low temperature circulation integrated machine is basically the same as that in Example 1. Furthermore, a sealing gasket 4 is provided inside the mounting cap 2, and the sealing gasket 4 is in contact with the inlet and outlet liquid pipes 101.

[0041] During the connection process between the mounting cap 2 and the inlet / outlet pipe 101, as the mounting cap 2 is rotated and fixed, the sealing gasket 4 is gradually compressed and eventually fits tightly against the inlet / outlet pipe 101, filling the gap between the mounting cap 2 and the inlet / outlet pipe 101 to form a seal. This effectively prevents liquid from leaking from the connection point, ensuring the normal operation of the high and low temperature circulation integrated machine, avoiding resource waste and equipment damage caused by liquid leakage, reducing safety hazards caused by leakage, and improving the safety of equipment operation.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
