Description

Technical Field

[0001] The present application relates to the technical field of ball playing cabinets, and in particular to a sealing structure of a barrel-type ball playing cabinet. Background Art

[0002] To provide a richer and more diverse dining experience, many buffet restaurants offer a wide variety of desserts. Ice cream, one of the most popular desserts, is often found on buffet tables. A bowling cabinet is a device specifically designed to hold ice cream. It's designed to preserve its quality during display and serving, while also providing customers with a more convenient self-service experience. While keeping the ice cream fresh and delicious while also facilitating self-service, it also needs to be kept at a low temperature to maintain its taste and quality. While traditional refrigerators or freezers can meet this requirement, they're not convenient for customers in a buffet setting. Bowling cabinets are equipped with efficient insulation and a refrigeration system to keep the ice cream at the perfect temperature while on display, preventing it from melting. Customers can reach directly into the ice cream, and a dedicated bowling spoon is provided for easy selection. Bowling cabinets feature a protective cover or transparent panel to prevent contaminants from entering, ensuring food hygiene. The cabinets are also easy to clean, allowing staff to disinfect them regularly.

[0003] As a container for ice cream, the ice cream cabinet consists of three main parts: a container, a fixed container, and an end cap. During use, the fixed container is placed inside the container and sealed with an end cap. However, this split structural design allows for cold air to escape through the joints, creating gaps between the components, leading to cold air leakage. This air leakage not only wastes energy but also causes the ice cream to melt faster, affecting its taste and quality. It also impacts the customer experience, especially in the hot summer months, when ice cream melts more easily and customers may find it less cold. Summary of the Invention

[0004] This device provides a barrel-type ball playing cabinet sealing structure, the specific implementation is as follows:

[0005] A barrel-type ball playing cabinet sealing structure, comprising:

[0006] A holding cylinder with an opening at the top and a fixed cylinder for placing the holding cylinder, the holding cylinder is sleeved in the fixed cylinder, and a sealing ring is provided between the fixed cylinder and the holding cylinder, the sealing ring acts on the connection between the fixed cylinder and the holding cylinder, and a plurality of arc-shaped sealing strips are arranged at intervals along the circumferential direction on the inner side of the sealing ring;

[0007] An openable end cover is provided on the top of the containing cylinder. A sealing member is provided on the peripheral side of the end cover to act on the inner side of the containing cylinder. The sealing member includes a vertical rubber cylinder. Several sealing rings are provided along the length of the vertical rubber cylinder. The arc-shaped sealing strips and sealing rings are used to solve the sealing problem at the connection position between the containing cylinder, the fixed cylinder and the end cover.

[0008] Based on the above technical solution, arc-shaped sealing strips and sealing members are added to solve the sealing problem at the connection position between the containing cylinder, the fixed cylinder and the end cover. The sealing ring is used for axial sealing between the fixed cylinder and the end cover. The arc-shaped sealing strip can form a tighter seal after the containing cylinder and the fixed cylinder are clamped together, ensuring that cold air will not leak out from the joint.

[0009] Preferably, a mounting bracket is integrated into the bottom of the fixing cylinder, and the sealing ring is installed at the bottom of the mounting bracket.

[0010] Preferably, the outer side of the sealing ring is provided with a hard ring body, the mounting frame is provided with a positioning ring downwardly through the cantilever, and the positioning ring, the hard ring body and the flange are connected through positioning through holes and bolts.

[0011] Preferably, the bottom diameter of the fixing cylinder is smaller than the top diameter of the containing cylinder.

[0012] Based on the above technical solution, the main part of the sealing ring is a ring body made of hard material, and the hard ring body is equipped with a circle of arc-shaped sealing strips with a certain elasticity, which can ensure that the sealing ring can better fit the interface between the containing cylinder and the fixed cylinder during the installation process, thereby improving the sealing effect; its installation positioning can achieve precise positioning of the sealing ring through the installation of the containing cylinder and the mounting frame, and firmly fix it in the predetermined position, avoiding poor sealing caused by position offset; the elastic arc-shaped sealing strip has a certain tension, which enables the sealing strip to automatically adjust the contact pressure between the containing cylinder and the fixed cylinder during the assembly process, thereby ensuring that the sealing effect of the sealing ring after installation is more reliable.

[0013] Preferably, the end cover is sequentially provided with a top cover portion, an equal diameter portion and a conical head from top to bottom, and the sealing member is installed at the equal diameter portion.

[0014] Preferably, the equal diameter portion is provided with a lateral mounting groove, which is a C-shaped structure with a flat protrusion in the middle. The inner side of the vertical rubber cylinder is a T-shaped structure and is filled with a hard block that abuts against the flat protrusion.

[0015] Based on the above technical solution, when the fixed cylinder and end cap are closed, the hard block contacts and interacts with the flat protrusion. The seal tilts during the closing process. When the fixed cylinder and end cap are closed, the hard block contacts the flat protrusion, causing the seal to tilt slightly, allowing it to better fit the gap between the fixed cylinder and the end cap, thereby improving the sealing effect.

[0016] Preferably, vertical protrusions are respectively provided at the upper and lower ends of the lateral mounting slot, and corresponding limiting grooves are opened on the inner side of the vertical rubber cylinder at the positions of the vertical protrusions.

[0017] Preferably, the sizes of the vertical protrusions at the upper and lower ends of the lateral mounting slot are different.

[0018] Based on the above technical solution, a seal with limiting grooves is designed, which not only improves the installation stability of the seal, but also ensures that the hard block will not separate from the end cover when tilted, thereby improving the overall sealing effect. These limiting grooves match the vertical protrusions in the lateral installation grooves to ensure that the seal can be accurately positioned during installation and remain stable during subsequent use.

[0019] Preferably, two sealing rings are integrally provided outside the vertical rubber cylinder along its length direction.

[0020] In summary, this application has the following beneficial technical effects:

[0021] 1. To ensure tightness at the junction of the containing cylinder, fixed cylinder, and end cap, and to prevent cold air from leaking out of the joints, this utility model solves the sealing problem by installing arcuate sealing strips and sealing members at the junction of the containing cylinder, fixed cylinder, and end cap. The arcuate sealing strips can better adapt to the shape differences between the different components, ensuring a tight seal at the connection. The sealing ring can effectively prevent cold air from leaking in the axial direction, ensuring tightness between the fixed cylinder and the end cap.

[0022] 2. The utility model provides an integrated hard ring and arcuate sealing strip for the sealing ring, so that the sealing ring can be installed and positioned by means of the installation of the container and the mounting frame. At the same time, the arcuate sealing strip has a certain degree of tension, making the assembly smoother.

[0023] 3. The utility model has a simple structure. By providing a flat protrusion, the flat protrusion interacts with the hard block of the seal so that after the fixed cylinder and the end cover are covered, the seal can produce a corresponding tilt, thereby achieving better sealing performance.

[0043] The following is combined with Figure 1-7 This application is described in further detail.

[0044] The embodiment of the present application discloses a sealing structure for a barrel-type ball playing cabinet.

[0045] Example 1

[0046] Reference Figures 1 to 3 and Figure 7 The present embodiment discloses a sealing structure of a barrel-type ball playing cabinet, comprising a containing cylinder 1 with an opening at the top, a fixed cylinder 4 for placing the containing cylinder 1, and an openable end cover 5 provided on the top of the containing cylinder 1. The containing cylinder 1 is sleeved in the fixed cylinder 4, and a sealing ring 3 is provided between the fixed cylinder 4 and the containing cylinder 1. The sealing ring 3 acts on the connection between the fixed cylinder 4 and the containing cylinder 1. A plurality of arcuate sealing strips 301 are arranged at intervals along the circumferential direction on the inner side of the sealing ring 3. A sealing member 7 acting on the inner side of the end cover 5 is provided on the circumferential side of the end cover 5. The sealing member 7 includes a vertical rubber cylinder 701. A plurality of sealing rings 702 are provided outside the vertical rubber cylinder 701 along its length direction. The arcuate sealing strips 301 and the sealing rings 702 are used to solve the sealing problem at the connection position between the containing cylinder 1, the fixed cylinder 4 and the end cover 5.

[0047] A mounting frame 2 is integrated at the bottom of the fixed cylinder 4, and a sealing ring 3 is installed at the bottom of the mounting frame 2. A hard ring body 302 is provided on the outside of the sealing ring 3. A positioning ring 201 is provided downwardly through the cantilever 202 on the mounting frame 2. The positioning ring 201, the hard ring body 302 and the flange 6 are connected by positioning through holes and bolts. The bottom diameter of the fixed cylinder 4 is smaller than the top diameter of the containing cylinder 1, which can prevent the containing cylinder 1 from sliding down from the inside of the fixed cylinder 4.

[0048] Example 2

[0049] Reference Figures 1 to 6 Based on the above embodiment, this embodiment also discloses a barrel-type ball playing cabinet sealing structure, in which the equal-diameter portion 502 is provided with a lateral mounting groove 5021, and the lateral mounting groove 5021 is in a C-shaped structure, in which a horizontal protrusion 5022 is provided in the middle, and the inner side of the vertical rubber cylinder 701 is in a T-shaped structure, and the interior is filled with a hard block 703 that abuts against the horizontal protrusion 5022.

[0050] The upper and lower ends of the lateral mounting slot 5021 are respectively provided with vertical protrusions 5023, and the inner side of the vertical rubber cylinder 701 is provided with corresponding limiting grooves 7011 at the position of the vertical protrusions 5023. In this structure, the vertical protrusions 5023 at the upper and lower ends of the lateral mounting slot 5021 are different in size.

[0051] The specific implementation process is as follows: the mounting frame 2 is directly connected to the ball game cabinet, and the fixed cylinder 4 containing ice cream is placed into the holding cylinder 1. At this time, the arc-shaped sealing strip 301 acts on the axial connection between the two, thereby enhancing the sealing effect. When the end cap 5 is fastened to the fixed cylinder 4, the vertical rubber cylinder 701 is constrained by the inner wall of the fixed cylinder 4, causing the hard block 703 to obliquely press the flat protrusion 5022. Under the action of the vertical protrusion 5023, the base of the vertical rubber cylinder 701 is stably installed in the lateral mounting groove 5021. Two sealing rings 702 act on the inner wall of the fixed cylinder 4, further improving the fastening effect between the end cap 5 and the fixed cylinder 4.

[0052] Many other changes and modifications can be made without departing from the concept and scope of the present invention. It should be understood that the present invention is not limited to specific embodiments, and the scope of the present invention is defined by the appended claims.
