Description
Technical field
The utility model belongs to sports apparatus, particularly relates to a kind of disabled person's weight bench barbell stand lifting regulating mechanism.
Background technology
In disabled person's powerlifting category, sportsman's arm length difference is apart from bigger, and the special-purpose weight bench specification of disabled person should guarantee that adjustable range is big, guarantees that again spacing is as far as possible little simultaneously.At present, the special-purpose weight bench barbell stand of known disabled person spacing is excessive, its spacing is generally 50mm, not only can't satisfy disabled person's instructions for use, and when need adjusting the adjustable height of barbell stand, need two people to lift erector at least after, adjust height simultaneously in the weight bench both sides by two people again, waste of manpower, and give to regulate to operate and bring inconvenience.
Summary of the invention
The utility model provides a kind of have stepless adjustment adjustable height, safe and reliable and easy to operate disabled person's weight bench barbell stand lifting regulating mechanism for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Disabled person's weight bench barbell stand lifting regulating mechanism, it is characterized in that: comprise bracket component, casing, handwheel turning cylinder, travelling gear, leading screw, screw, outer tube and locking handwheel, on the described bracket component casing is installed, by bearing the handwheel power transmission shaft is installed in the casing, handwheel power transmission shaft end key is connected with handwheel, handwheel power transmission shaft middle part key is connected with travelling gear, by bearing leading screw is installed vertically on casing top, leading screw lower end key is connected and installed with the travelling gear that is meshed with travelling gear on the handwheel power transmission shaft; Leading screw and the screw engagement that is installed on the carriage are connected with the outer tube that is sleeved on the leading screw outside at the casing top, and outer tube is provided with fairlead and stop screw, is connected with the locking handwheel in the outer tube outside.
The utility model can also adopt following technical scheme:
The outside of described outer tube is by the locking handwheel that has been threaded.
Described travelling gear is bevel gear.
Advantage and the good effect that the utlity model has are: because the utility model adopts above-mentioned mechanical transmission structure, promptly adopt the transmission of a pair of bevel gear and leading screw screw to cooperate, and utilized the characteristic that leading screw screw transmission device volume is little, output torque is big, substituted the troublesome operation that needs two people at least.This barbell stand lifting regulating mechanism is reasonable in design and easy to operate, has reliable self-locking performance.When adjusting the adjustable height of carriage, need not to lift erector, only need to rotate the just adjustable height of quick adjustment carriage easily of handwheel, realized step-less adjustment, so can satisfy handicapped athlete's arm length difference apart from the specific (special) requirements big, that weight bench barbell stand adjustable range is big and regulated quantity is little.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the K of Fig. 1 is to view;
Fig. 3 is the B portion enlarged drawing of Fig. 1.
Among the figure: 1, bracket component; 2, handwheel; 3, handwheel power transmission shaft; 4, casing; 5, outer tube; 6, screw; 7, fairlead; 8, stop screw; 9, leading screw; 10, bolt; 11, rolling bearing; 12, bevel gear; 13, bevel gear; 14, pressure bearing; 15, locking handwheel; 16, carriage.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1-Fig. 3, a kind of disabled person's weight bench barbell stand lifting regulating mechanism comprises bracket component 1, casing 4, handwheel turning cylinder 3, travelling gear 12 and 13, leading screw 9, screw 6, outer tube 5 and locking handwheel 15.By bolt casing 4 is installed on the described bracket component 1, by rolling bearing 11 handwheel power transmission shaft 3 is installed in the casing, handwheel power transmission shaft 3 ends are connected with handwheel 2 by bolt, back-up ring and key, and the middle part key of handwheel power transmission shaft 3 is connected with bevel gear 12.By pressure bearing 14 leading screw 9 is installed vertically on casing top, leading screw 9 lower ends are connected and installed with the bevel gear 13 that is meshed with bevel gear 12 on the handwheel power transmission shaft 3 by key; Leading screw 9 and screw 6 engagements that are installed on the carriage 16 are connected with the outer tube 5 that is sleeved on leading screw 9 outsides at the casing top by bolt 10, and outer tube 5 is provided with fairlead 7 and stop screw 8, are connected with locking handwheel 15 in the outside screw of outer tube 5.
Operation principle of the present utility model is as follows:
During turning handle 2, power transmission shaft 3 drives bevel gear 12 and rotates, and bevel gear 12 drives leading screw 9 with bevel gear 13 engagements and rotates, screw 6 engagements on leading screw 9 and the carriage 16, leading screw drives the screw motion, carriage is moved up and down, and then can realize the lift in height of weight bench barbell stand.Because the self-locking performance of leading screw screw transmission is good, carriage 16 can stop any position in the barbell stand height adjustment range, has realized the height step-less adjustment.Because erector is heavier, in use is easy to generate impulsive force, can increase the stability of apparatus like this by locking handwheel 15, make apparatus more safe and reliable.
