Problems solved by technology

In the existing horizontal bar, all components are fixedly connected. When the horizontal bar is stressed, the maximum friction force is increased through the pressure of the second suction cup, and the load-bearing capacity is increased. However, when the horizontal bar is stressed, a certain amount of deformation will occur, and the deformation amount It will cause the fixed seat to be deformed by force. When the maximum elastic deformation of the fixed seat is exceeded, it will not be able to rebound and cause deformation and damage to the equipment. In order to enhance reliability and prolong service life, the fixed seat needs to be made of high toughness and high strength materials, but Correspondingly, its production cost is also high, and then it needs to be structurally modified to reduce manufacturing cost while enhancing reliability

Embodiment Construction

[0021] The present invention will be further described below through specific embodiments.

[0022] refer to Figure 1 to Figure 5 As shown, a reinforced door frame horizontal bar includes a telescopic rod 1 and a support seat assembly.

[0023] The telescopic rod 1 includes an adjustment section 11 and two extension sections 12. The two extension sections 12 are respectively arranged at both ends of the adjustment section 11. The two extension sections 12 are respectively connected to the adjustment section 11 by positive and negative threads. By rotating the adjustment section 11 The two extension sections 12 can be extended or contracted simultaneously.

[0024] The support base assembly includes a first support base 2 , a second support base 3 , a support sleeve 4 and a support rod 5 .

[0025] Both the first support seat 2 and the second support seat 3 include a top pressure surface and two side wall surfaces. The top pressure surface is located on the outside of the su...

Abstract

The invention relates to the technical field of horizontal bars, in particular to a reinforced door frame horizontal bar. The reinforced door frame horizontal bar comprises a telescopic rod and is characterized in that supporting base assemblies are arranged at the two ends of the telescopic rod and comprise first supporting base, second supporting bases, supporting sleeves and supporting rods, the telescopic rod is sleeved with the supporting sleeves, the supporting sleeves are rotatably arranged on the first supporting bases, one end of each supporting rod is connected with the lower portionof the corresponding supporting sleeve, and the other end of each supporting rod is connected with the corresponding second supporting base. The supporting base assemblies of the door frame horizontal bar have a good supporting effect and are each provided with a good structure, the maximum supporting force capable of being provided by the supporting base assemblies can be synchronously increasedalong with increase of the stress of the telescopic rod, and installing is firmer.

Description

technical field [0001] The invention relates to the technical field of horizontal bars, in particular to a reinforced door frame horizontal bar. Background technique [0002] The door frame horizontal bar is a kind of portable fitness equipment, which can be installed and used on the ordinary door frame, which is convenient for exercising in the home and office. In order to increase the load capacity of the horizontal bar and the safety after overloading, the Chinese patent application publication number CN107050735 A discloses a combined horizontal bar for preventing overload, which includes a retractable horizontal bar body. The positive and negative telescopic rods are threadedly connected to the two ends of the screw rod, and a horizontal bar fixing seat assembly is respectively installed at the two ends of the single rod body. The support rod is provided with an internal threaded hole in the horizontal bar fixing seat, and the positive and square telescopic rods are re...
