Description

Technical Field

[0001] This utility model belongs to the field of refrigeration equipment technology, and in particular to a refrigerant diversion device for cold storage refrigeration equipment. Background Technology

[0002] A refrigerant distributor is a mechanical structure specifically designed for the diversion of refrigerant. Most existing refrigerant distributors are fixedly installed on the evaporator, making regular maintenance very inconvenient. Furthermore, current refrigerant distributors that can be disassembled suffer from poor sealing after installation.

[0003] A search revealed a Chinese patent document (authorization announcement number CN216557794U) describing a refrigerant distribution device for cold storage refrigeration equipment. The device involves an upper connecting pipe that penetrates a distribution cylinder. A lower base is snapped into the lower side of the distribution cylinder, and a side fixing ring is positioned on the upper side of the lower base. The outer wall of the side fixing ring is flush with the inner wall of the distribution cylinder. A fixing structure is located on the outer side of the distribution cylinder, passing through the distribution cylinder and engaging with a recessed hole on the side fixing ring. While this device facilitates disassembly and maintenance of the distribution cylinder, the seal between the distribution cylinder and the lower base is only achieved through a sealing groove or similar structure. Furthermore, the distribution cylinder and the lower base only have contact without any interaction force. Prolonged use may lead to a decrease in sealing effectiveness or even leakage. Therefore, a refrigerant distribution device for cold storage refrigeration equipment is urgently needed to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide a refrigerant diversion device for cold storage refrigeration equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a refrigerant diversion device for a cold storage refrigeration equipment, comprising an installation plate for installing the refrigerant diversion device in the cold storage refrigeration equipment and an installation cylinder for refrigerant diversion, wherein a circular groove is provided on the top surface of the installation plate, an annular groove is provided on the inner wall of the circular groove, and two vertical grooves are symmetrically provided on the inner wall of the circular groove, and the bottom of the vertical grooves communicates with the annular grooves.

[0006] Two arc-shaped blocks are symmetrically fixedly installed on the outer wall of the mounting cylinder, and the arc-shaped blocks match the vertical groove and the annular groove;

[0007] A top ring is slidably installed on the inner wall of the circular groove, and multiple limiting cylinders are fixedly installed at the lower end of the inner side of the circular groove. A telescopic rod is slidably installed inside the limiting cylinder, and the top surface of the telescopic rod is fixedly connected to the top ring.

[0008] A push spring is fixedly installed on the inner wall of the limiting cylinder, and the top surface of the push spring is fixedly connected to the bottom of the telescopic rod.

[0009] Preferably, the inner wall of the limiting cylinder has two symmetrically formed limiting grooves, and the side wall of the telescopic rod is symmetrically fixedly installed with limiting blocks.

[0010] Preferably, the two limiting blocks fixedly installed on the side wall of the telescopic rod are slidably connected to the inside of the two limiting grooves opened in the inner wall of the limiting cylinder.

[0011] Preferably, a sealing ring is fixedly bonded to the top surface of the top ring, and the top surface of the sealing ring is sealed to the bottom of the mounting cylinder.

[0012] Preferably, a sealing ring is fixedly bonded to the outer wall of the top ring, and the outer wall of the sealing ring slides and seals against the inner wall of the circular groove.

[0013] Preferably, rubber pads are fixedly bonded to the outer walls of the two arc-shaped blocks, and the rubber pads slide against the inner wall of the annular groove.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0015] The refrigerant distribution device of this cold storage refrigeration equipment benefits from the setting of two arc-shaped blocks, vertical grooves and annular grooves. The two arc-shaped blocks on the side wall of the mounting cylinder are aligned with the two vertical grooves respectively and pressed down until the arc-shaped blocks move into the interior of the annular groove. Rotating the mounting cylinder can make the arc-shaped blocks and vertical grooves staggered, thereby installing the mounting cylinder and the mounting plate.

[0016] The refrigerant distribution device of this cold storage refrigeration equipment benefits from the design of a circular groove, a top ring, a limiting cylinder, a telescopic rod, and a push spring. After the mounting cylinder is inserted into the circular groove, the bottom of the mounting cylinder will contact the top ring. Continuing to press the mounting cylinder down causes the telescopic rod to retract into the limiting cylinder and compress the push spring. The push spring pushes the top ring to make tight contact with the bottom of the mounting cylinder, which can further improve the sealing effect between the mounting cylinder and the mounting plate.

[0017] The refrigerant distribution device of this cold storage refrigeration equipment, thanks to the setting of the sealing ring, can effectively improve the sealing effect between the top ring and the inner wall of the circular groove, thereby further improving the sealing effect between the mounting cylinder and the mounting plate;

[0018] Compared with existing technologies, the refrigerant distribution device of this cold storage refrigeration equipment can effectively improve the sealing effect after the refrigerant distribution device is installed. Attached Figure Description

[0027] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0028] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0029] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0030] like Figures 1 to 5The main structure of the refrigerant distribution device of the cold storage refrigeration equipment shown is an installation plate 3 for installing the refrigerant distribution device in the cold storage refrigeration equipment and an installation cylinder 1 for refrigerant distribution. The top surface of the installation cylinder 1 is connected to the inlet pipe 2, and the bottom of the installation plate 3 is connected to the outlet pipe 4.

[0031] The top surface of the mounting plate 3 has a circular groove 5, the inner wall of the circular groove 5 has an annular groove 7, and the inner wall of the circular groove 5 has two vertical grooves symmetrically opened, and the bottom of the vertical grooves is connected to the annular groove 7. The outer wall of the mounting cylinder 1 has two arc-shaped blocks 6 symmetrically fixedly installed, and the arc-shaped blocks 6 match the vertical grooves and the annular groove 7. Thanks to the structure of the two arc-shaped blocks 6, the vertical grooves and the annular groove 7, by aligning the two arc-shaped blocks 6 on the side wall of the mounting cylinder 1 with the two vertical grooves respectively, and pressing them down until the arc-shaped blocks 6 move into the interior of the annular groove 7, rotating the mounting cylinder 1 can make the arc-shaped blocks 6 and the vertical grooves separate, thereby installing the mounting cylinder 1 and the mounting plate 3.

[0032] A top ring 8 is slidably installed on the inner wall of the circular groove 5. Multiple limiting cylinders 9 are fixedly installed at the lower end of the inner wall of the circular groove 5. A telescopic rod 10 is slidably installed inside the limiting cylinder 9, and the top surface of the telescopic rod 10 is fixedly connected to the top ring 8. A push spring 11 is fixedly installed on the inner wall of the limiting cylinder 9, and the top surface of the push spring 11 is fixedly connected to the bottom of the telescopic rod 10. Thanks to the structure of the circular groove 5, the top ring 8, the limiting cylinder 9, the telescopic rod 10, and the push spring 11, when the mounting cylinder 1 is inserted into the inner wall of the circular groove 5, the bottom of the mounting cylinder 1 will contact the top ring 8. As the mounting cylinder 1 is pressed down further, the telescopic rod 10 will retract into the limiting cylinder 9 and compress the push spring 11. At the same time, the push spring 11 pushes the top ring 8 to make close contact with the bottom of the mounting cylinder 1, thereby further improving the sealing effect between the mounting cylinder 1 and the mounting plate 3.

[0033] The inner wall of the limiting cylinder 9 has two symmetrical limiting grooves. The side wall of the telescopic rod 10 is symmetrically fixedly installed with limiting blocks 12. The two limiting blocks 12 fixedly installed on the side wall of the telescopic rod 10 are slidably connected to the inside of the two limiting grooves opened in the inner wall of the limiting cylinder 9. The limiting blocks 12 can effectively limit the sliding direction of the telescopic rod 10, and at the same time further improve the stability of the telescopic rod 10 and the top ring 8.

[0034] A sealing ring is fixedly bonded to the top surface of the top ring 8, and the top surface of the sealing ring is sealed to the bottom of the mounting cylinder 1. Thanks to the setting of the sealing ring, the sealing effect between the top ring 8 and the bottom of the mounting cylinder 1 can be further improved.

[0035] A sealing ring 13 is fixedly bonded to the outer wall of the top ring 8. The outer wall of the sealing ring 13 slides and seals against the inner wall of the circular groove 5. Thanks to the setting of the sealing ring 13, the sealing effect between the top ring 8 and the inner wall of the circular groove 5 can be effectively improved, thereby further improving the sealing effect between the mounting cylinder 1 and the mounting plate 3.

[0036] Rubber pads are fixedly bonded to the outer walls of the two arc-shaped blocks 6, and the rubber pads slide against the inner wall of the annular groove 7. The rubber pads against the inner wall of the annular groove 7 can make the arc-shaped blocks 6 have a damping effect in the annular groove 7, thereby further improving the stability of the arc-shaped blocks 6 inside the annular groove 7.

[0037] Working principle

[0038] When using the refrigerant distribution device of this cold storage refrigeration equipment, firstly, the bottom of the mounting cylinder 1 is inserted into the circular groove 5 opened on the top surface of the mounting plate 3. At the same time, the two arc-shaped blocks 6 on the side wall of the mounting cylinder 1 are aligned with the vertical groove and inserted into it. Then, the bottom of the mounting cylinder 1 will first contact the top ring 8. Subsequently, as the mounting cylinder 1 continues to press down, it will press down on the top ring 8 and compress the telescopic rod 10 into the limiting cylinder 9. At the same time, the push spring 11 is compressed until the arc-shaped blocks 6 on the side wall of the mounting cylinder 1 move into the annular groove 7. At this time, rotating the mounting cylinder 1 will cause the arc-shaped blocks 6 to be misaligned with the vertical groove, thereby achieving a seal between the mounting cylinder 1 and the mounting plate 3 and fixing the mounting cylinder 1 and the mounting plate 3.
