Description

The connecting ring of line cross protection pipe

The utility model relates to the connecting ring that uses on a kind of crossing protection tube of circuit.

In the prior art,, complicated overhead telephone line, power line, broadcast wire have particularly been formed throughout the country in the city along with the high speed development of post and telecommunications, electric power, broadcasting industry.The crossing that power high voltage line and telephone wire, broadcast wire intersect is seen everywhere, year in and year out, under the situation of blowing and raining, disconnected dropping on phone steel hinge line, the broadcast wire often takes place in high-voltage line, thereby causes that high pressure smashes the generation of phone, broadcast facility and the accident that creates greater casualties.A kind of line cross protection pipe is arranged at present; its structure is seen shown in the accompanying drawing 3; comprise ring, encircle down; the described lower openings that goes up ring also is connected with the upper opening of ring down; use brace between described upward ring and following the ring and be connected, the described bottom of encircling down is opening also, and the described lower opening that encircles down is provided with and the following brace of the downward extension that following ring is connected; be connected and fixed with upper fixing element between the described last brace, be connected and fixed with following fixture between the described following brace.Described upper fixing element or following fixture generally are that bolt matches with nut, also have to adopt the nail of blooming as fixture.Because the installation of protection tube usually is to carry out in the high-altitude, therefore above-mentioned fixture needs specialist tools when installing, and the fixture locking is inconvenient, and the skyborne installment work time is long.

The purpose of this utility model is to provide a kind of can make the fixture connecting ring of fixing line cross protection pipe fast.

The technical solution of the utility model is: a kind of connecting ring of line cross protection pipe, comprise ring, encircle down, the described lower openings that goes up ring also is connected with the upper opening of ring down, using brace between described upward ring and the following ring is connected, the bottom of described ring down is opening also, the described lower opening of ring down is provided with and the following brace that encircles the downward extension that is connected down, be connected and fixed with upper fixing element between the described last brace, be connected and fixed with following fixture between the described following brace; Described upper fixing element or following fixture are the self-locking pins that the surface has saw shape tooth, described self-locking pin is inserted in the pin jack that crosses described two last braces or two following braces, and the hole inwall of described pinning jack is provided with the locking teeth that is meshed with described saw shape tooth.

The utility model compared with prior art has following advantage:

Because the surface of self-locking pin has saw shape tooth, so the self-locking pin inserts the tooth of self-locking pin in back in the pin jack and meshes automatically with tooth in the jack and finish fixingly, do not need tool using during operation, so convenient fixing.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing 2 is the A-A direction cutaway view of accompanying drawing 1;

Three-dimensional structure diagram when accompanying drawing 3 uses jointly for connecting ring of the prior art and protection tube;

Accompanying drawing 4 is the B place zoomed-in view of accompanying drawing 2; Wherein:

[1]. protruding block; [2]. go up ring; [3]. go up the hole; [4]. upper fixing element; [5]. go up locking teeth; [6]. go up brace; [7]. following hole; [8]. encircle down; [9]. following fixture; [10]. following locking teeth; [11]. following brace; [12]. steel hinge line; [13]. the steel hinge line protection tube; [14]. cable; [15]. saw shape tooth; [16]. the pin jack; [17]. the self-locking pin; [18]. unlock button; [19]. the gap; [20]. locking teeth; [21]. the pinning seat.

Embodiment: referring to accompanying drawing 1,2,3, a kind of connecting ring of line cross protection pipe, comprise and be used for the upward ring [2] that protection tube passes, be used for the following ring [8] that cable passes, the described lower openings that goes up ring [2] also is connected with the upper opening of ring [8] down, the described ring [2] of going up is used brace [6] between [8] and is connected with encircling down, the bottom of described ring [8] down is opening also, the described lower opening of ring [8] down is provided with the following brace [11] of the downward extension that is connected with following ring [8], be connected and fixed with upper fixing element [4] between the described last brace [6], be connected and fixed with following fixture [9] between the described following brace [11]; Referring to accompanying drawing 4, described upper fixing element [4] or following fixture [9] are the self-locking pins [17] that the surface has saw shape tooth [15], described self-locking pin [17] is inserted in the pin jack [16] that crosses described two last braces [6] or two following braces [11], the hole inwall of described pinning jack [16] is provided with the locking teeth [20] that is meshed with described saw shape tooth [15], after inserting in the pinning jack [16], self-locking pin [17] can therefore not need the tool using locking by locking teeth [20] automatically with self-locking pin [17] locking.The upper surface of described self-locking pin [17] and lower surface are provided with saw shape tooth [15], to the fashionable positive and negative that does not need to differentiate self-locking pin [17] of pinning jack [16] interpolation, only need directly insertion to get final product at self-locking pin [17].The end of described self-locking pin [17] is provided with the pinning seat [21] of cross section greater than described pinning jack [16], is convenient to be pressed into self-locking pin [17] with hand.The hole lower inner wall of described pinning jack [16] is provided with locking teeth [20], can reduce manufacturing cost like this, and it is also passable that certain upper wall also is provided with locking teeth [20].The below of described locking teeth [20] has gap [19], the hole wall of the pinning jack [16] at described locking teeth [20] place stretches out and forms unlock button [18], when pressing down unlock button [18], can make locking teeth [20] break away from the saw shape tooth of self-locking pin [17], can in pinning jack [16], extract self-locking pin [17].Preferably described upper fixing element [4] and following fixture [9] all are the self-locking pins [17] that the surface has saw shape tooth [15], some continuously connected fasteners of blooming of selecting for use that also can be wherein.Described top of going up ring [2] is provided with the protruding block [1] that raises up, and its effect is tiltedly to slide on the steel hinge line [12] when preventing that high-voltage line is disconnected and dropping on the protection tube, causes charged casualty accident to making.
