CN201242605Y - Wire coil bracket for backpack optical cable releasing device - Google Patents

Abstract

The utility model particularly relates to a knapsack-type optical cable coiling and uncoiling device, which aims to provide a wire coil bracket used for the knapsack-type optical cable coiling and uncoiling device which is more suitable for one person. The wire coil bracket is characterized in that the wire coil bracket is mainly composed of a left side supporting arm (31), a main knapsack bracket (33) and a right side supporting arm (36); the left side supporting arm (31) and the right side supporting arm (36) are symmetrically arranged at two sides of the main knapsack bracket (33) to form a U shape structure for installing a wire coil supporting mechanism; the rear bracket surface (37) of the main knapsack bracket (33) is an arc-shaped knapsack surface which can be matched with the curved surface of the human body; a plurality of polygonal holes used for reducing the weight are arranged on the left side supporting arm (31), the right side supporting arm (36) and the main knapsack bracket (33); and an artificial leather foam-rubber cushion (34) is affixed through a nylon fastener tape on the arc-shaped knapsack surface (37). The performance requirement of the human body for the knapsack is fully considered in the structural design of the wire coil bracket, thereby ensuring that the process of coiling and uncoiling the optical cable in a knapsack way is more convenient and laborsaving.

Description

A kind of backpack optical cable draw off gear drum support

Technical field:

The utility model belongs to and relates to the backpack optical cable draw off gear that is used under a kind of lowered in field environment condition promptly laying with the rolling optical cable in the optical communication field.

Background technology:

In the prior art, the applicant has invented a kind of traditional optical cable take-up and pay-off device (referring to Fig. 1) once during the State's Ninth Five-Year Plan period.That this take-up and pay-off device has is collapsible, putting after the triangularity can be vehicle-mounted, be extended into behind the in-line to be lifted by two people and move or a series of functions such as push-and-pull, and is equipped with the unwrapping wire arrestment mechanism and receives around wire-arranging mechanism.But, thereby have a strong impact on the mobility of optical fiber cable for field operation folding and unfolding because the limit load of this take-up and pay-off device is up to 55kg.

The applicant has invented a kind of backpack optical cable draw off gear (referring to Fig. 2) again in 2007.Its drum support C and take-up handle B who has the drum supporting device by a tape spool formula folding and unfolding drum A, one pair and bear mechanism forms.Because in light weight, bear the rational in infrastructure of mechanism, thereby this device by single bearing after, in occasions such as regional electronics synthesis communication systems, created necessary condition for maneuverability ground lays the large-size optical cable repeatedly.

During the cloth cable, but this device is born unwrapping wire with both shoulders behind its take-up handle of removal B while moving ahead; During the rolling optical cable, this device that take-up handle B then will be installed moves to before the chest abdomen, in the face of desiring the optical cable of rolling, shakes the take-up handle while moving ahead, with the optical cable rolling to drum.The take-up handle can be installed arbitrarily on the left side or the right side of wire coil shaft.

Yet when the drum full load, the limit load of above-mentioned (Fig. 2) this backpack optical cable draw off gear also will reach 20kg; Thereby, still feel not very convenient by single long-distance when bearing this draw off gear.And, bear mechanism on its drum support C, and the stickiness between the human body abdomen back of the body is good inadequately, thereby influence comfort level, increasing bears a heavy burden feels.

Summary of the invention:

Technical problem to be solved in the utility model is to provide a kind of and more can be fit to the single backpack optical cable draw off gear drum support of bearing, thereby makes the weight of backpack optical cable draw off gear lighter, and performance is better, uses more convenient.

The utility model is achieved through the following technical solutions above-mentioned purpose:

A kind of backpack optical cable draw off gear drum support is characterized in that: described drum support is mainly born frame 33 by left side support arm 31, right side support arm 36 and master and is formed; Described left side support arm 31, right side support arm 36 are symmetricly set on main both sides of bearing frame 33, constitute " U " word shape, are used to install the drum supporting device; Described master bears the after-frame face 37 of frame 33, for bearing face with the arc that the human body curved surface fits; Described master bears on upper and lower the face of frame 33, all respectively is provided with two braces seats 35; Described left side support arm 31, right side support arm 36 and main bearing on the frame 33 are provided with several polygonal hole structures 32 that are used for loss of weight altogether.

Described arc is born on the face 37, has pasted leatheroid sponge mat 34 with velcro; Described leatheroid sponge mat is made by leatheret parcel foam-rubber cushion and is formed; Described velcro is buckled to take by female, male two and is formed; Described female or male sheet hasp are cemented in the main arc of bearing frame 33 and bear on the face 37, and corresponding male sheet or female hasp then are sutured in the relevant position of the leatheret cover of parcel foam-rubber cushion.

Described braces seat 35 is connected in main bearing on upper and lower the face of frame 33 by screw, is arranged on the spacing between main two braces seats 35 bearing on the frame 33 undercarriage faces, greater than being arranged on main put on the shelf the spacing between two braces seats 35 on the face of frame 33 of bearing.

The beneficial effects of the utility model are:

The structural design of drum support has fully taken into account human body to its performance requirement of bearing, and to bear folding and unfolding optical cable process more convenient, more laborsaving thereby make, and the work efficiency that makes backpack optical cable draw off gear carry out optical cable laying is further enhanced.
