Example one

As shown in fig. 1 to 10, the exercise chest expander with the training strength capable of being replaced quickly in this embodiment includes a handle main body, a tensile cord 1, and an inner sleeve 2, wherein the handle main body includes a handle 4 and an outer sleeve 3, the handle 4 is connected with the outer wall of the outer sleeve 3 to form a whole, the tail end of the inner sleeve 2 is connected with the end of the tensile cord 1, and the inner sleeve 2 and the tensile cord 1 are taken as a whole. The pull rope 1 is installed in the handle main part through interior sleeve pipe 2, and the handle main part can be used always as the main part that does not need the replacement, and different pull ropes 1 are replaced according to the training intensity of difference, reinforcing handle main part practicality reduces the wasting of resources. Be equipped with the protruding tooth 5 of outside extension on interior sleeve pipe 2 outer wall, be equipped with the spout 7 that the axial link up on the 3 inside walls of outer tube, interior sleeve pipe 2 passes through protruding tooth 5 and spout 7 sliding fit, makes interior sleeve pipe 2 can penetrate from 3 bottoms of outer tube to wear out from 3 tops of outer tube. 3 tops of outer tube are equipped with spacing joint hole 6, and joint hole 6 and spout 7 do not overlap or do not coincide, promptly interior sleeve pipe 2 stretch into after the outer tube 3, interior sleeve pipe 2 continues to wear out to 3 tops from the outer tube forward, interior sleeve pipe 2 is rotatory after, put into outer tube 3 with interior sleeve pipe 2 again, protruding

tooth

5 and 6 joints in joint hole, make when using the chest expander to stretch, interior sleeve pipe 2 can not the slippage with outer tube 3, the stability of tensile rope 1 and handle main part connection has been ensured, safety and reliability, it is spacing to interior sleeve pipe 2 simultaneously, the installation work of interior sleeve pipe 2 and handle main part is accomplished. When the pulling force rope 1 needs to be replaced, the convex teeth 5 of the inner sleeve 2 move upwards and are not clamped with the clamping holes 6, the inner sleeve is rotated to coincide with one ends of the convex teeth 5 and the sliding grooves 7, the pulling force rope 1 is pulled, the convex teeth 5 are connected with the sliding grooves 7 in a sliding mode, the inner sleeve is separated from the outer sleeve, and the pulling force rope 1 is separated from the handle main body. After the tension rope 1 is disassembled, the tension rope 1 with different strengths can be replaced according to requirements.

Install the block 10 that is used for restricting protruding tooth 5 and joint hole 6 and breaks away from on outer tube 3, the top tip at outer tube 3 is installed to block 10, and block 10 bottom and outer tube 3 contact, block 10 and outer tube 3 joint carry out spacing protection to inner tube 2, effectively ensure the stability of interior sleeve pipe 2 and outer tube 3 being connected. Be equipped with two arcs 11 that extend along its axial outside on the bottom surface of block 10, two arcs 11 symmetry sets up in block 10 bottom surface border department, and two arcs 11 can slide the cover locate on the outer tube 3 outer wall, and two arcs 11 inside walls are equipped with plush copper 8, are equipped with the recess 9 of cooperating the joint with plush copper 8 on the outer tube 3 lateral wall. The cap 10 is sleeved on the outer sleeve 3, and the raised head 8 is clamped with the groove 9. After the inner sleeve 2 is clamped with the outer sleeve 3, the cap 10 is sleeved from the top end of the outer sleeve 3, the raised head 8 on the inner side wall of the arc-shaped plate 11 is clamped with the groove 9 on the outer sleeve 3, and the whole installation is completed. When the cap is disassembled, one end of the arc plate 11 far away from the bottom is pulled outwards, so that the raised head 8 on the arc plate 11 is separated from the groove 9 and is not clamped any more, and the cap can be separated from the outer sleeve 3. According to different training modes, the handle body is arranged in a ring shape or a T shape. The handle body is annular, so that the handle is more convenient to use by single hand, the handle 4 is in a non-closed annular shape, and two ends of the handle 4 are both connected with the outer side wall of the outer sleeve 3 to form an annular shape; the handle main part is the T type and sets up and make things convenient for both hands to use more, and handle 4 is a style of calligraphy, and the center of handle 4 is equipped with the mounting groove, and outer tube 3 installs in the mounting groove to form the T type. The user can select the handle main body with different shapes according to the training items and the requirements of the user.

The inner sleeve 2 is in a round table shape, the area of the end face of the head end of the inner sleeve 2 is larger than that of the end face of the tail end, and the convex teeth 5 are arranged close to the head end. When interior sleeve pipe 2 is the round platform form, interior sleeve pipe 2 lateral wall is littleer with 3 inside wall contact surfaces of outer tube, and total frictional force between the two is little, more conveniently slides interior sleeve pipe 2 in outer tube 3. The installation is more convenient and quicker when the tension rope 1 is replaced. Protruding tooth 5 can set up a plurality of, sets up along circumference equipartition, and preferably, protruding tooth 5 sets up two to the centre of a circle is the axle, is the axial symmetry and distributes the setting, and spout 7 on the 3 inside walls of outer tube also is two, is 90 settings between protruding tooth 5 and the spout 7. Therefore, the stress is more uniform when the clamping is carried out. The convex direction of the convex teeth 5 is vertical to the axial direction of the inner sleeve 2, or extends obliquely towards the tail end of the inner sleeve 2. The inner sleeve 2 is not easy to be separated from the outer sleeve 3 due to overlarge tensile force, the safety of the chest expander is improved, and the personal safety of a user is ensured.

Handle 4 is the plastics handle, perhaps is the handle 4 that forms by the meshbelt preparation, and the meshbelt is for the belt of weaving, like the meshbelt that the knapsack was used, can satisfy 4 pulling force demands of handle with plastics or meshbelt homoenergetic, and preferably, establish the bubble cotton at 4 outer wall covers of handle, bubble cotton soft and have stronger frictional force, and the user uses more comfortable, also is difficult to follow the slippage in the hand, can not appear the condition such as reining in the hand. The common tensile rope 1 that is used for the chest expander has spring, emulsion tube, can select suitable tensile rope 1 according to the degree of user's training, preferably, selects the emulsion tube, and the emulsion tube elasticity is good, and weight is lighter, conveniently carries, and the cost is low. The handle body is provided with a plurality of outer sleeves 3, and the outer sleeves 3 are arranged in sequence or in an array. Set up a plurality of outer tubes 3 for can install a plurality of pulling force ropes 1 in the handle main part, increase the tensile scope of being suitable for of chest expander, satisfy more tensile strength demands. The chest expander has the advantages of simple structure, convenient installation and disassembly, rapid replacement, strong structural connection stability, strong practicability and good commercial value.
