The cylinder-type lock being distributed there are four even circumferential is set on cylindrical surface is closely assembled connecting column, the central axis of the locking assembly connection column
On the inner cylinder face that a connecting hole is kept away at the center, the thickness and the main body assembly connection column of the locking assembly connection column
Thickness it is identical, it is described locking assembly connection column front center position be equipped with a cylinder-type lock fasten connecting hole, it is described
The front of main body assembly connection column is equipped with arc-shaped part and is stably connected with slot, the center of arc's axis for being stably connected with slot and institute
The central axis for stating main body assembly connection column is identical, and the slot position that is stably connected with is described in the outside of the connecting hole that is locked
It is located at the position being locked between connecting hole and the mating groove that is connected together on the front of main body assembly connection column to set
The cylindrical heat-radiating ventilation connecting hole for thering is even circumferential to be distributed.
Further, the diameter that a connecting hole is kept away at the center is greater than the half of the main body assembly connection column diameter.
Further, the quantity of the heat dissipation ventilation connecting hole is 2 times of the mating groove that is connected together.
The utility model has the beneficial effects that
On former and later two end faces that the utility model is mounted on gear body structural member in assembly, to gear structure main body
Play the role of security protection, keep the overall security of gear structure in use more preferable, abrasion is smaller, and service life is more
It is long, it can reduce the whole use cost of gear structure in use.

Specific embodiment
As shown in Figures 1 to 4, a kind of gear structure protects stable connection pad, it is mounted on gear body knot in assembly
On former and later two end faces of component, plays the role of security protection to gear structure main body, make gear structure in use
Overall security it is more preferable, wear smaller, the service life is longer, can reduce gear structure in use whole and uses
Cost, its mode for being screwed in assembly link together with gear structure, and passes through and be arranged on this part
Heat dissipation ventilation structure, the heat that can be generated in gear structure use process carries out certain heat dissipation, so as to effectively prolong
In the service life of long tooth wheel construction in use, increase stability in use.It includes that cylinder-shaped body assembly connects
Column 1 is connect, the section that the external cylindrical surface of the main body assembly connection column 1 is equipped with even circumferential distribution is being connected together for inverted trapezoidal
The position of mating groove 2, the tooth that is connected together on the position and gear structure that it is assembled corresponds, and position is connected together mating groove
2 bottom position is higher than the bottom position of the engaging slot on gear structure in assembly, gear structure can be made to make in this way
