Description
Technical Field
The invention relates to the field of fitness equipment, in particular to a locking horizontal bar.
Background
With the development of society, people's living standard is improved, and the maintenance and exercise of the body are also more and more important. The more the need for exercise equipment. Particularly, the horizontal bar product is light and portable, almost occupies no use space, and is particularly suitable for families. However, most of the products on the market are not provided with a locking mechanism, so that looseness in use is easy to cause accidents. The small part of the shoe sole is also fixedly locked, and looseness caused by compression thinning or deformation of the pressure bearing surface of the shoe sole after long-time use cannot be eliminated.
Disclosure of Invention
The invention aims to provide a locking horizontal bar, which solves the problems in the prior art.
In order to achieve the above purpose, the present invention provides the following technical solutions: a locking horizontal bar is mainly formed by combining an outer tube, a left inner tube, a right inner tube, a screw rod combination and two ends of a foot support, wherein the rotatable direction between the inner tube and the outer tube is controlled through a pawl combination between the left inner tube and the right inner tube and between the outer tube. The specific structure is as follows: including the outer tube, the cover has middle bubble cotton on the outer tube, and the both ends cover that is close to the outer tube has the bubble cotton of shaking hands, and this has the screw rod subassembly in the outer tube, and the both ends of outer tube are connected with left inner tube and right inner tube respectively through the screw rod subassembly, and the outer end of left inner tube and right inner tube all is connected with the heel brace through the pipe plug, all is equipped with pawl subassembly between left inner tube and right inner tube and the outer tube.
The invention further improves that: the outer sides of the foot supports are provided with foot support pads.
The invention further improves that: the pawl assembly comprises a pawl positioning sleeve and a pawl sleeve cover, and the pawl positioning sleeve is connected with the pawl sleeve cover through a screw. A positioning boss and a positioning groove are arranged on the pawl positioning sleeve; the pawl sleeve cover is provided with a shifting block hole; a positive and negative shifting block is assembled in the pawl positioning sleeve, and a platform and a screw hole are arranged on the positive and negative shifting block; a positive and negative knob is arranged above the positive and negative shifting block; the left pawl and the right pawl are respectively arranged on two sides of the positive and negative shifting block; the left side of the left pawl is provided with a left pressure spring, and the right side of the right pawl is provided with a right pressure spring; an outer tube gear sleeve is arranged above the left pawl and the right pawl, and teeth and grooves are arranged on the outer tube gear sleeve. The positive and negative shifting block connected with the positive and negative knob ensures that the positive and negative shifting block and the positive and negative knob keep rotating in the same direction through a platform arranged on the positive and negative shifting block. When the positive and negative knob is in the loosening position, the positive and negative shifting block is in the right high left bottom position, at the moment, the left circular arc surface of the positive and negative shifting block compresses the left pawl, the left pressure spring is compressed, and the left pawl is separated from the teeth on the outer tube gear sleeve. The right pawl is pressed on the right side plane of the positive and negative shifting block due to the resilience force of the right pressure spring, and the position of the right pawl can just clamp the teeth on the outer tube gear sleeve. In this state, the right pawl is blocked in the left direction, and only the right direction is supported by the right pressure spring, so that the outer tube gear sleeve can only rotate anticlockwise and cannot rotate clockwise. Similarly, when the positive and negative knob is rotated to the right side, the positive and negative shifting block is arranged at the left high and right bottom position, at the moment, the right circular arc surface of the positive and negative shifting block compresses the right pawl, the right pressure spring is compressed, and the right pawl is separated from the teeth on the outer tube gear sleeve. The left pawl is pressed on the left plane of the positive and negative shifting block due to the rebound force of the left pressure spring, and the position of the left pawl can just clamp the teeth on the outer tube gear sleeve. In this state, the left pawl is blocked in the rightward direction, and only the leftward direction is supported by the left compression spring, so that the outer tube gear sleeve can only rotate clockwise and cannot rotate counterclockwise.
The invention further improves that: several outer tube bosses are uniformly arranged at two ends of the outer tube; the left inner tube is provided with a right-hand plug and a left inner tube groove, and the right inner tube is provided with a left-hand plug and a right inner tube groove. The screw assembly is provided with a right threaded end, a left threaded end and a screw fixing block, and the heel brace is provided with a heel brace boss.
Several bosses are uniformly arranged at two ends of the outer tube, and several matched grooves are formed in the outer tube gear sleeve, and the outer tube gear sleeve is tightly sleeved with the bosses of the outer tube through the grooves. Thus, the outer tube and the outer tube gear sleeve form a whole, and the outer tube gear sleeve rotates simultaneously when the outer tube rotates. The pawl locating sleeve and the pawl sleeve cover are locked by the screw to form a whole, and the locating boss arranged on the pawl locating sleeve is clamped in the groove of the right inner tube, so that the whole formed by the right inner tube, the pawl locating sleeve and the pawl sleeve cover can not rotate relatively and can only move mutually in the length direction. Similarly, the right inner tube is tightly propped against the heel brace through the tube plug, and at the moment, the right inner tube groove on the right inner tube is matched with the heel brace boss, so that the right inner tube and the heel brace are also equivalent to a whole in the circumferential direction, can not rotate relatively and can only move mutually in the length direction. The screw rod combination is arranged in the outer tube in the middle and is fixed with the outer tube through a screw rod fixing block (welded or riveted). Thus, when the outer tube is rotated, the screw rod combination brought into the inner tube is rotated, and the right-hand plug and the left-hand plug in the left and right inner tubes are driven to correspondingly rotate through the left-hand threaded end and the left-hand and right-hand threads of the right-hand threaded end which are arranged at the two ends of the screw rod combination. When in installation and use, one hand can hold the outer tube, and the other hand rotates the left inner tube and the right inner tube in turn to adjust to be close to the width of a door frame or other supporting walls to be installed. Then the anti-loose horizontal bar is plugged into the frame, the outer tube is rotated anticlockwise, and the right inner tube can only move to the right side after being limited to rotate due to the left-handed plug matched in the right inner tube. Similarly, the right-handed plug is arranged in the left inner tube, so that the left inner tube can move leftwards at the moment, and the aim of locking is fulfilled. Because of the effect of the pawl combination, before the positive and negative knob is not stirred, the outer tube can only rotate anticlockwise, that is to say, the horizontal bar can only be locked and cannot be loosened, and the anti-loosening purpose is achieved. In the long-time use process, if the heel brace pad is compressed and thinned or the supporting surface is deformed, the horizontal bar may be loosened, but because the outer tube which is gripped can be passively rotated along with the force of a user in the use process, and can only rotate in the anticlockwise direction, the inner tubes at two sides can be naturally stretched outwards, and the deformed part of the heel brace pad is compressed and thinned or the supporting surface is complemented. The horizontal bar is always in a locking state, so that the use safety is ensured. If the outer tube is to be detached, the outer tube can be easily removed by only adjusting the positive and negative knob to the other side and rotating the outer tube clockwise.
Compared with the prior art, the invention has the beneficial effects that:
The invention adds a ratchet mechanism capable of reversing positively and negatively between the inner tube and the outer tube of the single rod, and rotates the adjusting button to the locking direction during installation. During the installation and use process, the left-handed inner tube and the right-handed inner tube can only be rotated and stretched outwards, but cannot be rotated and shortened inwards. Therefore, before the disassembly, the long and long support surfaces can be ensured, and the support surfaces can be clamped on the wall bodies or door frames on two sides. Because the reverse direction cannot rotate, the locking can only be realized and the locking cannot be loosened. When the rotary knob is required to be disassembled, the rotary knob can be easily unscrewed by only reversing the rotary knob.
