Description

Technical Field

[0001] The utility model relates to the technical field of refrigerated trucks, and particularly relates to an installation structure of a chassis freezer for a refrigerated minibus. Background Art

[0002] Transactions of vegetables, fresh produce and various living supplies are required. In order to keep them for a longer time, they are often transported in a refrigerated box. Existing refrigeration units are mostly divided into independent units and split units. The independent unit is equipped with an imported silent engine for refrigeration, and the price is generally relatively high. The split unit drives the compressor for refrigeration by the vehicle's own engine, and the price is relatively economical. Some of the goods carried by the refrigerated truck have high requirements for the space inside the carriage, and the storage space of small and medium-sized minibuses is small, so it is inconvenient to transform them into special refrigerated trucks or add refrigeration units. Content of the Utility Model

[0003] The purpose of the utility model is to provide an installation structure of a chassis freezer for a refrigerated minibus to solve the problems existing in the above-mentioned prior art.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions:

[0005] An installation structure of a chassis freezer for a refrigerated minibus includes a freezer, an engine, and a bracket for bolt-connecting and fixing the front end of the freezer to the engine. The bracket includes a first component and a second component. The first component is provided with a plurality of through holes. The front top end of the first component is integrally formed with a left convex part and a right convex part. The front bottom end of the first component is integrally formed with a left supporting part and a right supporting part. The rear top end of the first component is integrally formed with a positioning part;

[0006] The bottom of the second component is provided with a front supporting part extending forward. The top of the front supporting part is provided with a through hole. A positioning rod is bolted from top to bottom in the through hole of the front supporting part. A positioning sleeve is welded to the top of the positioning rod. A waist-shaped hole is vertically arranged at the left end of the front side of the second component, and a plurality of through holes are arranged at the right end of the front side of the second component.

[0007] By adopting the above technical solution, the bracket where the first component and the second component cooperate can fix the refrigerator on the engine. The compartments of small or medium-sized minivans are relatively small, and when being retrofitted, split units rather than independent units are mostly used. Placing the refrigerator in the split unit in the compartment is not only troublesome to retrofit, but also will damage some goods stored in the compartment during the actual refrigeration process, which is not conducive to transportation. After fixing the refrigerator on the engine through the bracket, the spare space can be effectively utilized, and at the same time, the air quality in the storage space can be improved. Many of the bolted first components and second components adopt the connection method of straight thread sleeves. Straight thread sleeves are widely used in the construction field and can greatly improve their connection strength and are quite stable and reliable when used as connectors.

[0008] In a further embodiment, a waist-shaped hole is vertically arranged on the left side of the positioning part, a protruding part extending leftward is arranged on the top of the positioning part, and a through hole is arranged on the protruding part.

[0009] By adopting the above technical solution, the positioning part is mainly used for bolted fixing of the fixing device on one side of the refrigerator. At the same time, a clamping groove is arranged on one side of the refrigerator, which can be initially clamped and fixed with the protruding part and then the bolt is tightened, effectively improving the efficiency of on-site retrofit.

[0010] In a further embodiment, a receiving groove is arranged at the middle position of the top of the first component, a clamping groove is arranged at the middle position of the bottom of the first component, and an inclined angle is arranged on the right side of the top of the first component. The inclined angle of the first component is used to avoid the transmission.

[0011] By adopting the above technical solution, the receiving groove at the top can be used to receive some protruding parts of the transmission to avoid collision with it, while the clamping groove at the bottom can be engaged with the protrusion on the top cover of the engine.

[0012] In a further embodiment, an inclined angle is arranged on the left side of the top of the second component. The inclined angle of the second component is used to avoid the transmission.

[0013] By adopting the above technical solution, the second component is closer to the transmission side, so an inclined angle needs to be set for avoidance.

[0014] In a further embodiment, an acute angle rounding structure is arranged on the front side of the front supporting part.

[0015] By adopting the above technical solution, the acute angle rounding structure can prevent the front supporting part from bumping into other components due to bumps or the like during or after installation, causing problems such as depressions on other components, and improving the stability of the structure maintenance.

[0016] In a further embodiment, a through hole is provided at one end of the top of the left supporting portion close to the clamping groove, and a through hole is provided at one end of the top of the right supporting portion close to the clamping groove.

[0017] By adopting the above technical solution, the through holes on the left supporting portion and the right supporting portion are for facilitating bolt connection and fixing, while the supporting portion itself is for lifting the device to facilitate preliminary positioning.
