[0001] This utility model relates to an improvement of an accessory for a snow melting machine, particularly the locking structure of the material cylinder. Background Technology

[0002] In the field of cold beverage production, slush machines have become an extremely crucial and indispensable piece of equipment. Currently, slush machines generally adopt a horizontal design, with its basic structure consisting of a horizontally placed slush container and a matching main unit. Considering the differences in slush machine specifications, especially for small slush machines, a detachable locking device is mostly used to connect the container and the main unit's motor cover for easy daily cleaning and maintenance.

[0003] The utility model patents CN202423092038.4 and 202422225369.4 disclose a locking structure for a snow melting machine and a snow melting machine, respectively, and the utility model patent for the main body of a snow melting machine disclose an existing locking device of this type.

[0004] The existing latch body is composed of a circular latch block and a metal rod connected together. The metal rod has a ball handle or a strip handle at the end, which makes the assembly cost quite high.

[0005] In addition, after the material cylinder and motor cover of the snow melting machine adopt the structure of the locking device, the motor cover is a shell part with a complex structure. The existing locking design requires the setting of protrusions on the two outer planes to limit the locking, which greatly increases the complexity and difficulty of the motor cover mold design. Utility Model Content

[0006] In order to overcome the shortcomings of the current locking mechanism of snow melting machine, which increases the difficulty of opening the motor cover mold, this utility model provides a locking mechanism for the material cylinder of snow melting machine.

[0007] The technical solution of this utility model to solve its technical problem is: a locking mechanism for a snow melting machine cylinder, including a main body shell, a motor is provided on the upper rear end of the main body shell, a motor cover is fixedly provided on the outside of the motor, a cylinder is detachably provided on the front side of the motor cover, locking blocks with levers are rotatably provided on both sides of the motor cover, the two locking blocks are concentrically linked by a transmission shaft, the cylinder is provided with a locking protrusion, the locking block is provided with a locking channel with a side opening, the locking channel is surrounded by the locking channel side wall, the locking protrusion can be locked into the locking channel when the locking block rotates; the outer edge of the locking block is a ring of outer side wall, the outer side wall is provided with a stroke groove; the main body shell is provided with a stroke block protruding on the side facing the locking block, the head of the stroke block is located in the stroke groove; the wall of the stroke groove is provided with a stop protrusion to prevent the stroke block from retracting; a wave protrusion is provided in the middle of the locking channel side wall, the wave protrusion is located between the locking protrusion and the deepest part of the locking channel.

[0008] In a preferred embodiment, the distance between the gear shift protrusion and the stop end of the travel groove is such that the travel block is precisely engaged.

[0009] Further preferably, the gear shift protrusion has two parts, namely a left gear shift protrusion and a right gear shift protrusion.

[0010] To facilitate manufacturing and reduce production costs, the lever and locking block are integrally injection molded.

[0011] In a preferred embodiment, the locking protrusion consists of a circular boss and a fan-shaped plate on the side, with the fan-shaped plate facing downwards; the opening of the locking channel faces forward, and the lever is on top, rotating in a forward and downward direction.

[0012] To increase the structural strength of the lock track, the side wall of the lock track is provided with a thickened part near the lever, and the thickened part is provided with reinforcing ribs that run in the direction of the lever.

[0013] This utility model is used in the same way as existing snow melting machines, and will not be described in detail here.

[0014] The beneficial effects of this utility model are as follows: 1. The limiting structures on both sides of the original motor cover are transferred to the main body shell, reducing the mold opening cost and difficulty of the originally very complex motor cover. 2. The locking structure design of the snow melting machine in this application is flexible and convenient. The locking blocks are rotatably set on both sides of the motor cover, and the rotation stroke is limited by the stroke block and stroke groove. There are initial position and locking position. In the initial position, the material cylinder is easy to disengage, and in the locking position, it can be firmly fixed, which facilitates the installation and disassembly of the material cylinder. 3. The locking block and the lever are integrally injection molded, and the locking structure is sturdy and durable. The side wall of the locking channel near the lever is thickened and reinforced with reinforcing ribs in the longitudinal and other directions, which enhances the compressive and tensile strength of the side wall of the locking channel and extends the service life of the locking block. 4. The design of the gear protrusion on the stroke groove and the wavy protrusion on the locking channel prevents the locking block and lever from drooping and rotating due to gravity, and provides the operator with a jerky feeling during use, indicating that the operation is in place and improving the operating feel.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] Example 1 Combined with appendix Figures 1 to 7 A locking mechanism for a snow melting machine cylinder includes a main body shell 1. A motor is mounted on the upper rear end of the main body shell 1, and a motor cover 2 is fixedly mounted on the outside of the motor. A cylinder 3 is detachably mounted on the front side of the motor cover 2. Locking blocks 5 with levers 4 are rotatably mounted on both sides of the motor cover 2. The levers 4 and locking blocks 5 are integrally injection molded. The two locking blocks 5 are concentrically linked by a transmission shaft. Non-circular connectors 20 are provided at both ends of the transmission shaft and connected to the locking blocks 5. The cylinder 3 is provided with a locking protrusion 6, which is composed of a circular boss 16 and a fan-shaped blade 17 on the side, with the fan-shaped blade 17 facing downwards. The locking block 5 is provided with a locking channel 7 with a side opening facing forward. The lever 4 is on top and rotates in a forward and downward direction. The locking channel 7 is surrounded by a locking channel side wall 8. The side wall 8 near the lever 4 has a thickened portion 18, and this thickened portion 18 has reinforcing ribs 19 that align with the lever 4. The locking protrusion 6 can engage with the locking channel when the locking block 5 rotates. The outer edge of the locking block 5 is a ring of outer walls 9, and the outer walls 9 have travel grooves 10. The main body shell 1 has a travel catch block 11 protruding towards the locking block 5, and the head of the travel catch block 11 is located within the travel groove 10. The wall of the travel groove 10 has two shift protrusions 12 to prevent the travel catch block 11 from retracting. There are two shift protrusions 12: a left shift protrusion 14 and a right shift protrusion 15. A wavy protrusion 13 is located in the middle of the locking channel side wall 8, between the locking protrusion 6 and the deepest part of the locking channel. The distance between the shift protrusion and the stop end of the travel groove 10 is precisely enough to engage the travel catch block 11.

[0024] In this embodiment, the locking block 5 is rotatably mounted on both sides of the motor cover. The lower end of the locking block 5 is provided with a stroke groove 10. The head of the stroke block 11 is inserted into the stroke groove 10 to limit the stroke of the locking block 5. The locking block 5 has two stroke points: an initial position and a locking position. In the initial position, the locking protrusion 6 is located at the opening of the locking channel, and the material cylinder 3 can be easily disengaged from the mounting position. When the locking block 5 reaches the locking position after rotating one stroke, the locking protrusion 6 is engaged deep into the locking channel to complete the locking, and the material cylinder 3 is firmly fixed in front of the motor cover.

[0025] The advantage of this embodiment is that our locking block 5 and lever 4 are integrally injection molded. The locking channel side wall 8 of the locking block 5 is provided with a thickened part 18 on the side near the lever 4, and the thickened part 18 is provided with reinforcing ribs 19 in the direction of the lever 4 and reinforcing ribs in other directions, which are used to increase the compressive and tensile strength of the locking channel side wall 8 and improve the service life of the locking block 5.

[0026] The presence of the gear shift protrusions prevents the locking block 5 and the lever 4 from drooping and rotating due to gravity, and provides the operator with a tactile feedback when in use, indicating that the gear is in position. The wave protrusion 13 further enhances this operating feel.

[0027] The limiting structures on both sides of the original motor cover 2 have been transferred to the main body shell 1, which reduces the mold opening cost and difficulty of the original motor cover, which had a very complex structure.

[0028] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
