Embodiment Construction
[0025] See attached figure 1 -4, which describes a preferred embodiment of the retractable portable fixed insertion rod according to the present invention. The retractable and portable fixing rod includes a main rod 1, a tail rod 2, a locking body 7 and a thimble 5. The main rod 1 is a hollow cylindrical tube. The outer diameter of the tail rod 2 is slightly smaller than the inner diameter of the main rod 1. The tail rod 2 is sleeved inside one end of the main rod 1 (hereinafter referred to as the lower end). The sliding of the rod 1 is controlled by a locking device (not shown) on its sliding. When the locking device is adjusted to the "open" position, the tail rod 2 can slide along the inner wall of the main rod 1. When the locking device is adjusted to the "open" position, the tail rod 2 can slide along the inner wall of the main rod 1. When the position is closed, the tail rod 2 cannot move, and its relative position with the main rod 1 is fixed. No matter where the tail...

A telescopic and portable fixed inserted-rod comprises a main rod, a tail rod and a thimble, one end of the tail rod is sleeved with the main rod and can slide along the main rod which is in a hollow cylinder shape, and the cylindrical surface of the main rod is provided with a window communicated with the cavity inside the main rod; a lock catch is arranged inside the main rod and provided with a groove, and the position of the groove corresponds to that of the window; the thimble is arranged inside the main rod and on the upper portion of the lock catch, and the thimble is connected with the lock catch through a spring; a U-shaped steel wire is arranged inside the lock catch, at least one part of one side of the U-shaped steel wire penetrates through the groove, and at least one part of the other side of the U-shaped steel wire is inserted in the thimble. The telescopic and portable fixed inserted-rod is convenient to use repeatedly, beneficial to standardization management and capable of being widely applied to transformer substations in a company scope.
Description
technical field [0001] The invention relates to an insertion rod, in particular to a two-stage retractable and conveniently portable fixed insertion rod. Background technique [0002] With the development of the urban economy, power supply and heating wells are gradually spreading in the streets and alleys of the city. In practical applications, when the power supply and heating fail or the system needs to be inspected and repaired, it is usually necessary to enter and deal with it from the well. During the above processing, in order to ensure safety, it is necessary to arrange certain safety measures to isolate the maintenance equipment from the operating equipment. Usually, the safety facilities include safety belts. [0003] The use of the safety girdle fixed inserting rod in the prior art is not economical and reasonable, and the work efficiency is not high. This is mainly manifested in the fact that most of the currently used safety belt fixed inserting rods are about...
