reference numerals in the drawings of the specification include: the device comprises a top plate 1, a pulley 2, a pull rope 3, a pull ring 4, a guide rod 5, a base block 6, an air cushion 7, a buffer sleeve 8, a base 9, a piston 10, a spring 11, a buffer cavity 12, a ball 13, an oil cavity 14, a U-shaped groove 15, a connecting hole 16, a weight increasing block 17, a cam 18, a gear 19 and a rack 20.
Example one
As shown in fig. 1 to 4, a wall chest expander for rehabilitation comprises a top plate 1, a base 9, guide rods 5, balancing weights and pull ropes 3, wherein four guide rods 5 are vertically fixed between the top plate 1 and the base 9, two guide rods 5 form a group, and each group of guide rods 5 is slidably connected with a group of balancing weights. Every group balancing weight all includes a foundation block 6 and a plurality of weight block 17 that increases, all shows its dead weight on foundation block 6 and the weight block 17 that increases, and foundation block 6 sliding connection is on guide arm 5, and weight block 17 and guide arm 5 can dismantle and be connected. Specifically, it has two vertical guide holes to open on the basis piece 6, a set of two guide arms 5 alternate respectively in two guide holes, it has two U type grooves 15 to open on the piece 17 that increases weight, U type groove 15 and guide arm 5 sliding connection, U type groove 15 runs through the piece 17 that increases weight in vertical direction, the opening in U type groove 15 extends to one side that increases weight 17, it has connecting hole 16 to open between U type groove 15, it places on basis piece 6 to increase weight 17, make guide arm 5 card go into U type groove 15 in, stay cord 3 is located connecting hole 16, can install weight 17.
The top of foundation block 6 is opened there is the spread groove (not shown in the figure), and pre-buried fixed hook in the spread groove, stay cord 3 bottom mounting have the hookup, and the hookup colludes on the fixed hook, and stay cord 3 free end is fixed with pull ring 4, and the rotation is installed in roof 1 bottom to be used for the pulley 2 for the direction of stay cord 3, and the tensioning of stay cord 3 is on pulley 2.
The base block 6 and the weight increasing block 17 are both provided with oil chambers 14 for containing lubricating oil, the side surfaces of the oil chambers 14 are communicated with oil pipes (not shown in the figure), and valves are arranged on the oil pipes. Two rows of balls 13 are rotatably arranged on the inner walls of the guide hole and the U-shaped groove 15, two sliding grooves are axially formed in the left side and the right side of the guide rod 5, the two rows of balls 13 are respectively in rolling fit with the two sliding grooves, and one part of each ball 13 is positioned in the oil cavity 14 and is contacted with lubricating oil.
The specific implementation process is as follows:
the balancing weight is located 5 bottoms of guide arm under initial condition, and the pulling rope 3 is pulled up the balancing weight during the use, releases the balancing weight down of stay cord 3, so relapse can train limbs. The foundation blocks 6 are always connected to the guide rods 5 in a sliding mode, and the number of the weight increasing blocks 17 can be increased or decreased according to training strength in practical use, so that the training purpose is achieved.
After releasing the balancing weight, the balancing weight gliding under the action of gravity, cushion collar 8 stretches out base 9 top under the initial condition, earlier with cushion collar 8 contact before balancing weight and the contact of base 9, press cushion collar 8 down, spring 11 compresses, cushion collar 8 drives the gas in piston 10 extrusion cushion chamber 12 above that, cushions the impact force of balancing weight gliding jointly through cushion collar 8, gas and spring 11, make its comparatively slow fall on base 9. Meanwhile, the air in the buffer cavity 12 is extruded into the air cushion 7, the air cushion 7 is filled on the surface of the base 9 after expanding, the balancing weight falls on the air cushion 7 after reaching the base 9, the balancing weight is buffered again, the direct impact of the balancing weight on the base 9 is avoided, the service lives of the balancing weight and the base 9 are prolonged, and the noise generated by impact is also reduced.
When the balancing weight slides along the guide rod 5, the balls 13 on the balancing weight can roll in the sliding groove on the guide rod 5, so that the sliding friction between the guide rod 5 and the balancing weight is changed into rolling friction, the friction force is effectively reduced, the balancing weight can slide more smoothly, the abrasion of the guide rod 5 is reduced, and the service life of the balancing weight is prolonged. Because ball 13 partly is located oil pocket 14, can carry lubricating oil to the spout when ball 13 rolls in, realize the lubrication of guide arm 5, further reduce the friction for the balancing weight slides more smoothly. When the portable oil pump is carried and transported, the valve can be opened to discharge lubricating oil in the oil cavity 14, so that the weights of the base block 6 and the weight increasing block 17 are reduced, and the portable oil pump is convenient to transport and carry.
Example two
The difference between this embodiment and the first embodiment is that, as shown in fig. 5, a cam 18 is rotatably disposed on the left side of the U-shaped groove 15, a convex portion of the cam 18 can abut against the guide rod 5, a gear 19 is coaxially connected to the cam 18, and a rack 20 is engaged with the outer side of the gear 19.
When the weight increasing block 17 is installed, the rack 20 is pulled outwards, the rack 20 drives the gear 19 and the cam 18 to rotate, so that the cam 18 is released from the U-shaped groove 15, and the guide rod 5 can be smoothly clamped into the U-shaped groove 15; after the guide rod 5 is clamped into the U-shaped groove 15, the rack 20 is pushed back, the gear 19 and the cam 18 rotate reversely, and the cam 18 abuts against the guide rod 5, so that the guide rod 5 is positioned, the connection stability of the guide rod 5 and the weight increasing block 17 is improved, and the installation stability of the weight increasing block 17 is further improved.
