Description
Technical field
The utility model belongs to electrical equipment technical field, especially a kind of mounting structure of middle-placed switch cabinet chassis vehicle roller.
Background technique
Currently, for filling the chassis vehicle of breaker, including vehicle frame, roller on traditional middle electrical cabinet, roller
Mounting means is the two sides that roller is loaded on to vehicle frame side wall using axle screw and nut, and when actual production needs roller manually
Wheel is set on screw, is then passed through side wall, then roller is connected on side wall by nut, and there are operative employee's duration, knots
Structure is unfavorable for Automated assembly, causes productivity effect low, usually again not easy to disassemble, it has not been convenient to maintenance.
Summary of the invention
It is a kind of simpler than prior art operation that in order to overcome the deficiencies of the prior art, the utility model provides, facilitates dimension
Shield maintenance, conducive to the mounting structure of the middle-placed switch cabinet chassis vehicle roller assembled on automatic assembly line.
To achieve the goals above, the technical solution adopted in the utility model is: a kind of peace of middle-placed switch cabinet chassis vehicle roller
Assembling structure, including vehicle frame, further include connecting shaft, are set in connecting shaft and around the roller that connecting shaft rotates, the connecting shaft with
One end of roller axially position, the connecting shaft is connect with vehicle frame, and the other end is connect with roller, and the connecting shaft is circumferentially provided with
First annular groove, the roller include the connecting hole being cooperatively connected with connecting shaft, are circumferentially provided on the hole inner wall of connecting hole
Second annular groove is provided between the first annular groove and second annular groove and enables axis between the connecting shaft and roller
To the retainer ring of positioning.
Using the above scheme, one end of connecting shaft is connect with vehicle frame, first annular recessed by setting up in connecting shaft week
Connecting hole is arranged in slot on roller, and second annular groove is arranged on the hole wall of connecting hole, and first annular groove and the second annular are recessed
Slot is oppositely arranged, and retainer ring can be enabled to play positioning action between first annular groove and second annular groove, can be with
Roller is rotated in connecting shaft along first annular groove, and facilitates installation.It can be reduced by above-mentioned structure
Operating time when installation, while its structure is simple, is conducive to Automated assembly, so that productivity effect greatly improves, usually needs
It is also very easily disassembled when wanting maintenance.
As the further setting of the utility model, the left and right sidewall of the second annular groove respectively with the hole of connecting hole
It is provided with firmly lower from connecting shaft disassembly radially convenient for roller between wall or installs the chamfering of connecting shaft.
Using the above scheme, chamfering is set with the hole wall of connecting hole respectively in the left and right sidewall of second annular groove, so that
Roller can remove or install connecting shaft from connecting shaft by the way that chamfering is convenient when exerting oneself radially.
As the further setting of the utility model, the groove depth of the first annular groove is less than the second annular groove
Groove depth.
Using the above scheme, when roller is rotated relative to connecting shaft, the groove depth of first annular groove is recessed less than the second annular
It can make when the groove depth of slot more stable after cooperating retainer ring, it is not easy to fall off, in addition also more convenient connecting shaft and roller
Between installation and removal, improve productivity effect.
As the further setting of the utility model, the groove depth of first annular groove is the 1/2 of second annular groove groove depth.
As the further setting of the utility model, it is provided in the connecting shaft convenient for connecting shaft quick insertion roller company
Connect the conehead in hole.
Using the above scheme, facilitate connecting shaft that can utilize the characteristic of conehead when being inserted into roller, more accurately carry out
Grafting installation.
The utility model is further described with reference to the accompanying drawing.
Detailed description of the invention
Attached drawing 1 is the utility model specific embodiment appearance diagram；
Attached drawing 2 is the cross-sectional view of the utility model specific embodiment A-A；
Attached drawing 3 is the enlarged drawing in the portion the utility model specific embodiment B；

Specific embodiment
Specific embodiment of the utility model is as shown in Figs 1-4, and specific embodiment of the utility model is as shown in Figs 1-4,
A kind of mounting structure of middle-placed switch cabinet chassis vehicle roller 3, including vehicle frame 1 further include connecting shaft 2, are set in connecting shaft 2 and around even
The roller 3 that spindle 2 rotates, the connecting shaft 2 and 3 axially position of roller, one end of the connecting shaft 2 is connect with vehicle frame 1, another
End is connect with roller 3, and the connecting shaft 2 is circumferential to be provided with first annular groove 21, and the roller 3 includes cooperating with connecting shaft 2
The connecting hole 31 of connection is circumferentially provided with second annular groove 32, the first annular groove 21 on the hole inner wall of connecting hole 31
The retainer ring 4 for enabling the connecting shaft 2 and 3 axially position of roller is provided between second annular groove 32.
In the present embodiment, the left and right sidewall of the second annular groove 32 is arranged between the hole wall of connecting hole 31 respectively
Have firmly lower from the disassembly of connecting shaft 2 radially convenient for roller 3 or installs the chamfering of connecting shaft 2.
In the present embodiment, the groove depth of the first annular groove 21 is less than the groove depth of the second annular groove 32, excellent
The groove depth of selection of land first annular groove 21 is the 1/2 of 32 groove depth of second annular groove.
In the present embodiment, it is provided in the connecting shaft 2 convenient for the cone of 2 quick insertion roller of connecting shaft, 3 connecting hole 31
First 22.
