Fixing device for fixing water pump connecting rod

Abstract

The invention discloses a fixing device for fixing a water pump connecting rod. The fixing device includes a lower fixing device, a concave surface of the lower fixing device, limiting surfaces, a lower fixing device vertical interface, an input fixing buckle, an upper fixing device, an upper fixing device vertical interface and a limiting hole; the limiting surfaces are machined in the lower fixing device through turning; limiting holes are machined between the limiting faces, the input fixing buckle is arranged below the lower fixing device, the upper fixing device is installed above the lower fixing device, the upper fixing device vertical interface is machined above the upper fixing device, and the lower fixing device vertical interface is machined above the concave face of the lower fixing device. The fixing device is simple in design, reasonable in manufacturing, not large in modification and compact in structure, the phenomenon that the limiting middle column is loosened due torotating force and friction force is effectively prevented, the loosening problem of the double middle columns is better solved, the stainless steel pin is used to prevent rusting in water, durable, convenient to use, rapid and capable of improving safety.

Description

technical field [0001] The invention relates to the technical field of preventing loosening of a connecting rod of a water pump, in particular to a fixing device for fixing a connecting rod of a water pump. Background technique [0002] The most important part of the water pump is the bearing. The connecting rod in the bearing is particularly important. During the use of the water pump, the connecting rod is easy to loosen and cannot be fixed effectively, resulting in great losses. Therefore, the connection rod of the water pump Anti-loosening plays a key role. The connecting rod of the pump is fixed. The double-column fixing method has been used to prevent loosening. It is easy to cause the shaft sleeve to fall off and cause product quality accidents. [0003] In view of the above shortcomings, it is necessary to design and develop a fixing device for fixing the connecting rod of the water pump, which can make up for the above shortcomings.

[0002] The most important part of the water pump is the bearing. The connecting rod in the bearing is particularly important. During the use of the water pump, the connecting rod is easy to loosen and cannot be fixed effectively, resulting in great losses. Therefore, the connecting rod of the water pump Anti-loosening plays a key role. The connecting rod of the pump is fixed. In the past, the double center column fixing method was used to prevent loosening. It is easy to cause the shaft sleeve to fall off and cause product quality accidents.
