Detailed Description

As shown in fig. 1-4, the adjusting and locking mechanism of the horizontal bar comprises a bar body 1, wherein the bar body 1 comprises a bar main body 2, a loose joint component 3 and an adjusting bar 4 which are sequentially connected, the bar body 1 is adjusted by the loose joint component 3 in a telescopic mode, the loose joint component 3 comprises inner conical teeth 5, outer conical teeth 6 and a fixing nut 7, the outer conical teeth 6 are fixedly assembled with the bar main body 2, and the inner conical teeth 5 are circumferentially assembled with the adjusting bar 4 in a linkage mode. The outer bevel gear 6 and the lever main body 2 are relatively fixed, and the inner bevel gear 5 and the adjusting rod 4 are relatively fixed, so that only the relative assembly relation between the outer bevel gear 6 and the inner bevel gear 5 needs to be adjusted. When the outer conical teeth 6 are separated from the inner conical teeth 5, the lever body 2 or the adjusting rod 4 can be adjusted in a rotating mode, and otherwise, the outer conical teeth 6 are meshed with the inner conical teeth 5, so that the whole structure is fixedly integrated. The bar body 1 can be adjustable at one end or both ends, and is not limited herein, mainly for illustration at the locking structure. The conical surface area of the conical tooth is large, the stress intensity is large, the engagement and disengagement switching process between the outer conical tooth 6 and the inner conical tooth 5 is short, and the design and use requirements are met.

The fixing nut 7 is in blocking fit with the inner conical teeth 5 in the axial direction, the outer conical teeth 6 are in threaded connection with the fixing nut 7, the inner conical teeth 5 axially move by rotating the fixing nut 7, and the inner conical teeth 5 are in a meshed state or a separated state with the outer conical teeth 6. Interior awl tooth 5 is last to have the installation department 8 that supplies fixation nut 7 to assemble and restriction axial displacement's fender portion of connecting 9, be equipped with on the 7 inside walls of fixation nut and keep off ring 10, still be equipped with jump ring 11 on the installation department 8, keep off that connecting 9, fender ring 10 and jump ring 11 keep off in proper order and connect the setting. The fixed nut 7 is sleeved on the inner bevel gear 5 and slides to one side of the tooth surface of the inner bevel gear 5, and reaches the end point at the blocking part 9 to limit the movement. During installation, the fixing nut 7 is firstly sleeved on the installation part 8, and then the clamp spring 11 is sleeved on the installation part 8. The snap spring 11, also called a retainer ring or a snap ring, belongs to one type of fastener, is arranged in a shaft groove or a hole groove of a machine or equipment and plays a role of preventing parts on a shaft or a hole from moving axially. Here, the circlip 11 mainly limits the reverse disengagement of the fixing nut 7, avoiding the loose frame of the structure at this point in the adjustment process.

The outer bevel gear 6 one end is equipped with fretwork groove 12, is equipped with fixed muscle 13 on the fretwork groove 12 inner wall, 2 tip of thick stick main part are equipped with grooving 14, fixed muscle 13 inserts grooving 14 fixed, and interference fit between outer bevel gear 6 and thick stick main part 2. The fixing ribs 13 and the cutting grooves 14 are used for assisting in fixing, so that slipping can be prevented during circumferential rotation, and the linkage effect is enhanced.

The inner bevel gear is characterized in that a matching groove 15 is formed in one end of the inner bevel gear 5, a V-shaped rib 16 is arranged on the wall of the matching groove 15, a V-shaped groove 17 is formed in the adjusting rod 4, and the inner bevel gear 5 is inserted into the V-shaped groove 17 through the V-shaped groove 17 to be fixedly matched. In a similar way, the connection tightness of the structure is enhanced, and linkage matching is promoted. The adjusting rod 4 is partially inserted into the bar body 2, and after the horizontal bar is extended or the adjusting rod 4 is extended, the retraction and resetting can be avoided through a spring designed inside the horizontal bar, which is a mature technical means and a variety of ways, and the limitation is not limited to the way.

The outer side wall of the fixing nut 7 is provided with a plurality of anti-slip grooves 18 which are uniformly distributed, so that the hand of a human body can conveniently hold and rotate.

The principle is summarized as follows: when the width of the horizontal bar needs to be adjusted, the fixing nut 7 is screwed out for 1-2 circles, namely the inner conical teeth 5 are driven to be separated from the outer conical teeth 6, and the horizontal bar main body 2 or the adjusting rod 4 is rotated to move axially to be adjusted. When the required position is reached, the inner conical teeth 5 and the outer conical teeth 6 can be meshed and locked by screwing the fixing nut 7. The principle of locking is mainly explained, and the rest are mature technical means, which are not explained and limited too much here.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the position or positional relationship based on the position or positional relationship shown in the drawings, and are only for convenience of description, and are not intended to indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific orientation, and therefore, are not to be considered as limitations of the present invention, and the fundamental principles, main features, and advantages of the present invention have been shown and described above, as would be understood by those skilled in the art.
