[0002] At present, for refrigeration equipment in the market, such as display cabinets, upright refrigerators, refrigerators, etc., their door bodies are all equipped with door handles, and users open the door bodies by pulling the handles. Since when the refrigeration equipment closes the door body, in order to ensure the sealing performance of the box body and avoid heat exchange between the inside of the box and the outside, a sealing strip with a magnetic strip is provided on the contact surface between the door body and the box body, which strengthens the adsorption of the glass door to prevent cold air from leaking and increases power consumption. In addition, when the refrigeration equipment operates with the door body closed, a large negative pressure will be generated inside the box body. The suction force of the door seal magnetic strip and the negative pressure environment generated inside the box during operation together cause a significant increase in the opening resistance of the door. Opening the door requires a lot of force to complete. If the cabinet is not loaded and its own weight is insufficient, the force to open the door body forward may even cause the entire cabinet to tip forward, posing a safety hazard. Therefore, a handle structure that is labor-saving when opening the door while maintaining the sealing performance of the door body is needed. Summary of the Utility Model

[0003] To solve the problem in the prior art that the opening resistance of the door is large due to the suction force of the door seal magnetic strip and the negative pressure environment generated inside the box during operation, the utility model provides a handle structure, which is arranged on the opening side of the door body of the refrigeration equipment. The refrigeration equipment includes a door body and a box body. A door seal strip is arranged on the edge of the door body. The handle structure is characterized by including an outer handle and an inner handle. The outer handle is fixedly connected to the door body. The inner handle includes a connecting rod, a handle inner frame and a separating piece. The connecting rod is in a scissor fork-shaped structure, having a short force arm and a long force arm. A strip-shaped connecting hole is arranged at the intersection of the connecting rod. A hinge shaft that is slidably hinged to the connecting rod is arranged in the strip-shaped connecting hole. The hinge shaft is arranged on the side wall of the door body. The handle inner frame is arranged inside the outer handle and is hinged to the long force arm side of the connecting rod. The separating piece is arranged between the door seal strip and the box body. The connecting rod transmits the pulling force for opening the door to the separating piece, separating an opening between the door seal strip and the box body.

[0004] Specifically, the outer handle includes a handle outer frame and a connecting piece. The handle outer frame is fixedly connected to the connecting piece, and the connecting piece is fixedly connected to the door body.

[0005] Specifically, the connecting pieces are arranged at the upper end and the lower end of the handle outer frame.

[0006] Specifically, the handle inner frame is in a "U" shape, including a rear frame and side frames. The handle inner frame is movably connected to the handle outer frame, and a chamber is formed between the handle inner frame and the handle outer frame.

[0007] Specifically, a spring is provided in the cavity, with one end of the spring attached to the rear side of the handle frame and the other end attached to the front side of the rear frame.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This utility model provides a handle structure, including an inner handle and an outer handle. The inner handle uses a connecting rod with a scissor-fork structure to connect the inner frame of the handle and the partition plate. The force applied to the long lever arm is amplified by the connecting rod and transmitted to the partition plate located on the short lever arm, causing the partition plate to move forward and separate the door seal from the box body to create an opening. This allows some air to enter the box body through the opening, balancing the air pressure inside and outside the box body. With a smaller force applied, the box body can be opened, making opening the door easier. Users do not need to pull the handle forcefully to open the door, reducing the risk of the box body tipping over and improving safety performance. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. The specific implementation of the present utility model will be described in detail below with reference to specific embodiments.

[0017] like Figures 1-4As shown in the figure, to solve the problem that in the prior art, the negative pressure environment generated inside the box during the operation of refrigeration equipment leads to a large resistance when opening the door, the present utility model provides a handle structure, which is arranged on the opening side of the door body 1 and includes an outer handle and an inner handle. The inner handle is connected to the separating piece 8 by a scissor-like connecting rod 6. When the handle is pulled, the connecting rod 6 transmits the pulling force to the separating piece 8, and the separating piece 8 separates the door seal 3 from the door body 1, making the internal and external air pressures balanced, thereby reducing the resistance when opening the door and achieving the purpose of labor saving.

[0018] This handle structure is applied to refrigeration equipment such as refrigerators, display cabinets, and cold storage cabinets. The refrigeration equipment includes a box body 2 having an internal chamber and a door body 1 hinged to one side of the box body 2 for opening and closing the internal chamber. A door seal 3 for sealing the door body 1 is provided at the edge of the door body 1.

[0019] The outer handle is fixedly installed on the side wall of the door body 1 and includes a handle outer frame 4 and a connecting member 5. The connecting member 5 is arranged at the upper and lower ends of the handle outer frame 4 and is fixedly connected to the handle outer frame 4 by bolts. The connecting member 5 is fixedly connected to the door body 1 by bolts.

[0020] The inner handle is movably connected to the side wall of the door body 1 and includes a connecting rod 6, a handle inner frame 7, and a separating piece 8. The connecting rod 6 is of a scissor-like structure with a short force arm and a long force arm. A strip-shaped connecting hole 9 is provided at the intersection of the connecting rod 6, and a hinge shaft 10 is arranged in the strip-shaped connecting hole 9. The hinge shaft 10 is fixedly installed on the side wall of the door body 1. The handle inner frame 7 is hinged to the long force arm side of the connecting rod 6, and the separating piece 8 is hinged to the short force arm side of the connecting rod 6.

[0021] The handle inner frame 7 is in a "U" shape and includes a rear frame 11 and side frames 12. The handle inner frame 7 is arranged inside the handle outer frame 4. The handle inner frame 7 is movably connected to the handle outer frame 4, and a chamber is formed between the handle inner frame 7 and the handle outer frame 4. The side frames 12 are fitted on both sides of the handle outer frame 4 to provide guidance for the forward and backward movement of the handle inner frame 7.

[0022] The separating piece 8 is in an "L" shape and is inserted between the box body 2 and the door seal 3. The door seal 3 is made of an elastic material. When the handle is pulled, using the lever principle, the force applied to the long force arm side is amplified by the connecting rod 6 and transmitted to the separating piece 8 located on the short force arm, causing the separating piece 8 to move forward, separating the door seal 3 from the box body 2 to form an opening, so that part of the air can enter the box body 2 through the opening, making the air pressures inside and outside the box body 2 balanced, and then a smaller force can be applied to open the box body 2.

[0023] A spring 13 is further arranged in the chamber. One end of the spring 13 is fitted to the rear side of the handle outer frame 4, and the other end is fitted to the front side of the rear frame 11. The spring 13 is fixedly connected to the handle outer frame 4 or the rear frame 11 by gluing. After the user releases the handle, the handle inner frame 7 automatically returns to its original position under the elastic force of the spring 13.

[0024] With the door closed, hinge 10 is located in front of the strip-shaped connecting hole 9. When the inner handle is pulled, it drives the connecting rod 6 and the partition plate 8 forward. The partition plate 8 presses against the door seal 3, creating an opening between the door seal 3 and the box 2. Some air enters the box 2 through this opening, balancing the air pressure inside and outside the box 2. At this point, hinge 10 is located behind the strip-shaped connecting hole 9. Pulling the inner handle further opens the door 1. This handle makes opening the door effortless. Even without using the handle, the door 1 maintains a good seal. Using this handle structure, users can open the door 1 without pulling the handle forcefully, reducing the risk of the box 2 tipping over and improving safety.
