Description

Technical Field

[0001] This utility model belongs to the field of auxiliary device technology, and more specifically, it relates to an auxiliary device for opening the door of a medical refrigeration equipment. Background Technology

[0002] A low-temperature freezer is a device specifically designed for storing medical supplies. Its temperature is controlled below -25°C, and it is commonly used to store items such as plasma, reagents, and samples. When the door is closed, the incoming hot air cools rapidly and contracts in volume, creating negative pressure that causes the door to adhere tightly to the freezer. This negative pressure phenomenon is due to the excellent sealing effect of the door seal, resulting in the air intake being far less than the internal air contraction. Therefore, users need to apply considerable force when opening the door. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a door opening assistance device for medical refrigeration equipment, which solves the problem that users need to apply considerable force when opening the door after it has been closed.

[0004] The purpose and function of this utility model, a door opening auxiliary device for medical refrigeration equipment, are achieved by the following specific technical means:

[0005] A door opening auxiliary device for medical refrigeration equipment includes a refrigeration equipment cabinet; two sliding seats are fixed to the front face of the refrigeration equipment cabinet, a cabinet door slides on the two sliding seats, and a handle is fixed to the cabinet door; a mounting block is fixed to the rear face of the cabinet door, a locking rod is welded to the left end face of the mounting block, and a slot with an annular groove structure is opened on the locking rod; a seat is fixed to the left end face of the inner wall of the refrigeration equipment cabinet, the seat has a concave structure, a connecting seat is welded to the seat, a guide rod slides on the connecting seat, and a locking block is fixed to the bottom end face of the guide rod, the locking block is engaged in the slot.

[0006] Furthermore, a first electromagnet is fixed on the connecting seat. The first electromagnet is located directly above the guide rod, which is made of iron. When the first electromagnet is energized, the guide rod is attracted to the first electromagnet under its attraction.

[0007] Furthermore, a sensor switch is installed on the handle, and a microprocessor is installed inside the handle. The sensor switch, the microprocessor, and the first electromagnet are electrically connected.

[0008] Furthermore, the mounting block, locking rod, slot, base, connecting seat, guide rod, locking block and first electromagnet together form an auxiliary component. The locking rod is a cylindrical rod structure, and the insertion end of the locking rod is polished, resulting in an arc-shaped structure.

[0009] Furthermore, two adsorption blocks are fixed on the left end face of the inner wall of the refrigeration equipment cabinet. Both adsorption blocks are made of iron. Two permanent magnets are fixed on the cabinet door. When the cabinet door is closed, the two permanent magnets and the two adsorption blocks are in an adsorption state.

[0010] Furthermore, a third electromagnet is fixed on the base, and a second electromagnet is fixed inside the mounting block. The second and third electromagnets are aligned. When the cabinet door is closed, the second and third electromagnets come into contact. The second and third electromagnets have the same magnetic poles. Both the second and third electromagnets are electrically connected to the microprocessor inside the handle. The repulsive force between the second and third electromagnets is greater than the attraction force of the two permanent magnets.

[0011] Furthermore, a rectangular plate-shaped auxiliary plate is fixed to the rear end face of the cabinet door. The auxiliary plate is rectangular plate-shaped, and a sealing gasket is attached to the left end face of the auxiliary plate. The left end face of the sealing gasket is in contact with the left end face of the inner wall of the refrigeration equipment cabinet.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] When a person grips the handle, the sensor switch triggers the microprocessor, energizing the first electromagnet to attract the iron guide rod, which in turn causes the locking block to disengage from the locking rod slot, achieving keyless automatic unlocking. This makes the operation convenient and improves efficiency.

[0014] The locking rod insertion end is polished into an arc shape, which can automatically lift the locking block when the cabinet door is closed, making the locking process smoother, reducing component wear and reducing the difficulty of operation.

[0015] After the cabinet door is closed, the permanent magnet attracts the adsorption block, and together with the sealing gasket on the auxiliary plate, it contacts the cabinet body, providing double protection for sealing performance. This effectively prevents cold air leakage, maintains stable temperature inside the equipment, and meets the stringent environmental requirements for storing medical supplies.

[0016] In addition, the second electromagnet on the cabinet door has the same magnetic poles as the third electromagnet in the cabinet. When unlocking, the two like poles repel each other to generate a pushing force, and the repulsive force is greater than the attraction force of the permanent magnet. This can assist the cabinet door to open automatically, which is especially suitable for medical staff when their hands are busy, reducing the need for manual pushing. Attached Figure Description

[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0027] like Figures 1 to 5 As shown, this embodiment provides a door opening auxiliary device for medical refrigeration equipment, specifically including a refrigeration equipment cabinet 1. Two sliding seats 101 are fixed on the front end of the refrigeration equipment cabinet 1, and a cabinet door 102 slides on the two sliding seats 101. A handle 103 is fixed on the cabinet door 102. A mounting block 201 is fixed on the rear end of the cabinet door 102. A locking rod 202 is welded to the left end of the mounting block 201. A groove 203 with an annular groove structure is opened on the locking rod 202. A seat 204 is fixed on the left end of the inner wall of the refrigeration equipment cabinet 1. The seat 204 has a concave structure. A connecting seat 205 is welded on the seat 204. A guide rod 206 slides on the connecting seat 205. A locking block 207 is fixed to the bottom end of the guide rod 206 and is engaged in the groove 203.

[0028] A first electromagnet 208 is fixed on the connecting seat 205. The first electromagnet 208 is located directly above the guide rod 206, which is made of iron. When the first electromagnet 208 is energized, the guide rod 206 is attracted to the first electromagnet 208. The locking rod 202 is unlocked by the attraction between the guide rod 206 and the first electromagnet 208.

[0029] The handle 103 is equipped with a sensor switch 104 and a microprocessor is installed inside the handle 103. The sensor switch 104, the microprocessor, and the first electromagnet 208 are electrically connected. When a person grips the handle 103, they make contact with the sensor switch 104. The sensor switch 104 sends a signal to the microprocessor, which then turns on the power to the first electromagnet 208, thus completing the unlocking action.

[0030] The auxiliary component 2 is composed of the mounting block 201, locking rod 202, slot 203, base 204, connecting seat 205, guide rod 206, locking block 207 and first electromagnet 208. The locking rod 202 is a cylindrical rod structure. The insertion end of the locking rod 202 is polished and has an arc-shaped structure. When the locking rod 202 is inserted into the base 204, it will be smoother. Due to the arc-shaped part of the insertion end of the locking rod 202, the locking block 207 can be automatically lifted when the cabinet door 102 is closed.

[0031] Two adsorption blocks 5 are fixed on the left end face of the inner wall of the refrigeration equipment cabinet 1. Both adsorption blocks 5 are made of iron. Two permanent magnets 6 are fixed on the cabinet door 102. When the cabinet door 102 is closed, the two permanent magnets 6 and the two adsorption blocks 5 are in an adsorption state. The seal at the cabinet door 102 can be completed through the adsorption of the two permanent magnets 6 and the two adsorption blocks 5.

[0032] A third electromagnet 4 is fixed on the base 204, and a second electromagnet 3 is fixed inside the mounting block 201. The second electromagnet 3 and the third electromagnet 4 are aligned. When the cabinet door 102 is closed, the second electromagnet 3 and the third electromagnet 4 come into contact. The second electromagnet 3 and the third electromagnet 4 have the same magnetic poles. Both the second electromagnet 3 and the third electromagnet 4 are electrically connected to the microprocessor inside the handle 103. The repulsive force between the second electromagnet 3 and the third electromagnet 4 is greater than the attraction force of the two permanent magnets 6. When a person holds the handle 103, they make contact with the induction switch 104. The induction switch 104 sends a signal to the microprocessor, which turns on the power to the second electromagnet 3 and the third electromagnet 4. The second electromagnet 3 and the third electromagnet 4 automatically open the door under the repulsive action of their like poles.

[0033] A rectangular auxiliary plate 105 is fixed to the rear end face of the cabinet door 102. The auxiliary plate 105 is a rectangular plate structure. A sealing gasket 106 is attached to the left end face of the auxiliary plate 105. The left end face of the sealing gasket 106 contacts the left end face of the inner wall of the refrigeration equipment cabinet 1. The contact between the left end face of the sealing gasket 106 and the left end face of the inner wall of the refrigeration equipment cabinet 1 can improve the sealing performance of the cabinet door 102.

[0034] Working principle: When a person grips handle 103, they make contact with induction switch 104. Induction switch 104 sends a signal to microprocessor, which then powers on the first electromagnet 208, completing the unlocking action. Simultaneously, induction switch 104 sends a signal to microprocessor, which powers on the second electromagnet 3 and the third electromagnet 4. The second electromagnet 3 and the third electromagnet 4 automatically open the door due to the repulsion between like poles. When closing cabinet door 102, the curved part of the locking rod 202 automatically lifts the locking block 207 as the door closes, and the locking block 207 finally engages in the slot 203 to complete the locking.
