Description

Electrician's skate

Technical field

The utility model belongs to the instrument field of climbing usefulness, relates in particular to a kind of tiing up and climb the device that column, cylinder or type bar are used on pin.

Background technology

Electrician's skate is commonly called as " climbers ", the indispensability that is a kind of electrician when the various wooden or concrete wire pole of climbing step on the bar safety appliance.

November 11 1998 day for announcing, a kind of " climbers " are disclosed in the Chinese patent of notification number CN2296742Y, one side of its pin dish 14 is fork 12 and button 7 fixedly, the prong of fork 12 connects T shape plate 9, the other end of button 7 and triangle conduit 5 are fixing, are with triangle movable hook 2 in the triangle conduit 5.But it exists triangle movable hook rigidity intensity on its load-bearing direction little, can bear lightweight deficiency, simultaneously, because it has adopted fixed non-slipping block structure at the end of triangle movable hook circular arc portion, the position quick abrasion that non-slipping block often contacts with electric pole, replacing inconvenience have caused shorten the service life of entire product.

The utility model content

The rigidity intensity that technical problem to be solved in the utility model provides a kind of expansion link is big, good toughness, can bear bigger weight, can adapt to vary in diameter, longer service life and safer electrician's skate of line bar better.

The technical solution of the utility model is: a kind of electrician's skate is provided, comprise pedal, be arranged at first non-slipping block of pedal one side, connect with pedal and an end has the connecting rod of sleeve pipe and passes the expansion link of sleeve pipe, the cross section of the part body of rod that it is characterized in that described expansion link is for oval or intersect formed structures by a rectangle and two circular arcs; The cross section of sleeve pipe and containing expansion link identical with the cross section of expansion link; Be provided with second non-slipping block of gimbal structure at described expansion link one end.

Wherein, the cross section of the body of rod of the straight bar part of described expansion link is hollow ellipse shape or intersects formed hollow-core constructions by a rectangle and two circular arcs.

Its described second non-slipping block that has gimbal structure comprises that an end has the fixed bar of hemispherical projection, has jut and the fixed head of centre bore is arranged and is arranged on non-slip rubber block on the fixed head, fixed bar passes the centre bore of fixed head and connects with expansion link, and the hemispherical jut of fixed bar cooperates the formation gimbal structure with the jut of fixed head; Described non-slip rubber block parcel is arranged on the fixed head.

It is stupefied that the contact-making surface of described first non-slipping block and second non-slipping block and electric pole is provided with non-slip process; The stupefied contact-making surface surface at first non-slipping block or second non-slipping block of non-slip process forms rhombus, circle, rectangle or linear figure.

Compared with the prior art, the utility model has the advantages that:

1. because expansion link adopts oval or intersect formed hollow-core construction by a rectangle and two circular arcs, sectional dimension on its load-bearing direction is big, thus expansion link integral intensity height, good toughness, compare with the expansion link of footpath hollow steel pipe manufacturing with employing, can bear bigger weight.

2. adopt second non-slipping block that has gimbal structure, the vary in diameter that can adapt to the line bar better guarantees that non-slipping block is constant with the contact area of line bar, increased with the line bar armful and power, not easy to wear, help increasing the security and the reliability of stepping on bar operating personnel work.

3. that non-slip process is set is stupefied on the surface of non-slipping block, has increased the frictional force of its contact-making surface, more stable during use, non-slip; Simultaneously, second non-slipping block adopts non-slip rubber block to wrap up the version that is arranged on the fixed head, is convenient to change, and has prolonged the actual life of entire product.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is an overall structure schematic diagram of the present utility model;

Fig. 2 is the A-A ' cross section structure schematic diagram of embodiment;

Fig. 3 is the A-A ' cross section structure schematic diagram of another embodiment;

Fig. 4 is the structural representation of second non-slipping block.

1 is pedal among the figure, and 2 is first non-slipping block, and 3 is connecting rod, and 4 is sleeve pipe, and 5 is expansion link, and 6 is second non-slipping block.

The specific embodiment

Among Fig. 1, but first non-slipping block 2 of a side setting axial rotation of pedal 1, the connecting rod 3 that one end has sleeve pipe 4 is fixedly connected with pedal, expansion link 5 passes sleeve pipe and is in slidably mobile status, be provided with second non-slipping block 6 of gimbal structure at expansion link one end, the cross section of the part body of rod of expansion link is oval or intersects formed structures by a rectangle and two circular arcs; The cross section of sleeve pipe and containing expansion link identical with the cross section of expansion link.

Among Fig. 2, the cross section of the straight line portion body of rod of connecting rod 3 and expansion link 5 is a hollow ellipse shape structure, and the cross section of sleeve pipe 4 is identical with the cross section of expansion link and contain expansion link, and sleeve pipe and expansion link are slidingly matched, and Socket welding is connected on the connecting rod.

Owing to adopt above-mentioned body of rod version, to compare with the expansion link of footpath hollow steel pipe manufacturing with employing, the face size of the utility model on the load-bearing direction of expansion link is big, so expansion link integral intensity height, good toughness can bear bigger weight.
