Lower pressing reinforcing 8；For the reinforcing bar 8 of different-diameter, the distance between two bearings 2 L is different；Therefore, it is curved in large batch of reinforcing bar
In song experiment, staff needs that the very big time is spent to go to measure and adjust the distance between two bearings 2, cumbersome.
Utility model content
The technical problems to be solved in the utility model is that the reinforcing steel bar bending tester of the prior art uses connecting rod and nut tune
The distance between two bearings of section, it is long to adjust the required time, influences bend test efficiency.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of reinforcing bar adjusted using gear
Apparatus for Bending at low-temp, including pedestal, bearing, stent, connecting rod, driving gear and driven gear；
The surface of pedestal is provided with a sliding slot, and two bearings are mounted in sliding slot, and bearing can change position along sliding slot
It puts；
Stent is mounted on pedestal, and driving gear and driven gear are installed on stent, driving gear and driven gear
Engagement；Generally adding the combination of two driven gears using a driving gear, two driven gears are arranged on driving gear both sides,
Driving gear synchronizes two driven gears of driving；
The center of each driven gear is fixedly connected with a connecting rod, and the surface of connecting rod is provided with two sections of oppositely oriented spiral shells
Line, connecting rod are threadedly coupled using two sections of screw threads with two bearings respectively, and connecting rod is parallel with sliding slot；
When staff rotates driving gear, two driven gears and the connecting rod being fixed on driven gear synchronize rotation
Turn, the connecting rod of rotation drives two bearings close to each other or separate, realizes that the distance between bearing is adjusted.
Further, the connector for being connect with can be manually rotated tool is provided in the middle part of the driving gear.
Further, the carrying axle for being capable of spinning is provided on the bearing, carrying axle is used to carry steel to be bent
Muscle.
Advantageous effect：The Apparatus for Bending at low-temp of the utility model adjusts the distance between two bearings using gear set, not only
It is easy to operate laborsaving, and degree of regulation higher, greatly improve the efficiency that bar bending is tested.

Specific embodiment
The utility model is described in further detail With reference to embodiment.
Embodiment 1
As shown in Figures 3 to 5, the reinforcing steel bar bending tester of the present embodiment, including 1, two bearing 2 of pedestal, stent 3, two
A connecting rod 4, driving gear 5 and two driven gears 6；
The surface of pedestal 1 is provided with a sliding slot 11, and two bearings 2 are mounted in sliding slot 11, and bearing 2 can be along sliding slot
11 change position, and the carrying axle 21 for being capable of spinning is provided on bearing 2, and carrying axle 21 is used to carry reinforcing bar to be bent；
Stent 3 is mounted on pedestal 1, and driving gear 5 and driven gear 6 are installed on stent 3, two driven gears 6
5 both sides of driving gear are arranged on, driving gear 5 is engaged with driven gear 6, and driving gear 5 synchronizes two driven gears 6 of driving；
The middle part of driving gear 5 is provided with the connector 51 for being connect with can be manually rotated tool；
The center of each driven gear 6 is fixedly connected with a connecting rod 4, the surface of connecting rod 4 be provided with two sections it is oppositely oriented
Screw thread, connecting rod 4 is threadedly coupled using two sections of screw threads with two bearings 2 respectively, and connecting rod 4 is parallel with sliding slot 11；
