Description
Technical field
The present invention relates to a kind of square tube hermetically sealed connector.
Background technology
In general, just build the city of subway, all enter water in the groove box of at least AFC ground wiring of Article 1 subway, cable is immersed in water not rarely seen.The subway owner of experience and lessons and engineering unit was had to cause the attention of height to the waterproof problem of AFC resistant ground wiring groove, box.
At first, Metro AFC ground wiring system be adopt traditional floor socket outlet groove, box carries out laying.Because traditional ground wiring system waterproof requirement is not high, so within the general all IP44 of degree of protection.Find after being used by domestic many AFC systems: groove box internal memory leaves a large amount of underground water, and the cable of quite a few is immersed in underground water, certainly also have partial cables line to cause crust damaged at work progress, therefore drain conditions certainly exists.
In order to solve the seepy question of Metro AFC wiring system groove, box, this just requires the degree of protection improving groove, box, i.e. dense water energy.By demonstration, degree of protection generally will reach IP67 and just meet waterproof requirement.So some Metro AFC ground domestic wiring is because the way of employing Site Welding that needs of waterproof solves this problem.Because general steel plate carried out surface treatment (the general method of hot galvanizing that adopts is to improve the decay resistance of steel), such general steel plate is just not suitable for welding at the scene.Because the anticorrosive coat of Site Welding meeting deface, weld will damage at short notice in corrosion, still the phenomenon of leaking easily is caused, based on above reason, domestic many Metro AFC ground wiring system, adopt stainless steel material to do grooving, box, then carry out assembled welding at the scene, improve the waterproof ability of groove, box with this.Certainly, this also serves certain waterproof effect, but is increased on-the-spot difficulty of construction.Be multiplied again investment simultaneously.Because Site Welding can produce naked light, too increase the potential safety hazard producing fire.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, the square tube hermetically sealed connector that fit sealing performance is good, easy to use.
Technical solution of the present invention is:
A kind of square tube hermetically sealed connector, is characterized in that: comprise brace, lower brace; Upper brace to comprise slice and with upper slice vertical lateral plate, upper slice one end is slope form, slope nearside is arranged installs the waist-shaped hole of tightening bolt, and be slide plate form with the lower end of upper slice vertical lateral plate, slide plate nearside arranges the waist-shaped hole installing time tightening bolt; Lower brace comprises bottom sheet and the lateral plate vertical with bottom sheet, and one end of bottom sheet is slope form, and slope nearside arranges lower tightening bolt, and the upper end of the lateral plate vertical with bottom sheet is slide plate form, and slide plate nearside arranges the hole of installing tightening bolt; Upper brace, lower brace are connected by upper tightening bolt, lower tightening bolt and corresponding attaching nut; Slide plate on upper brace, in the tightening process of lower tightening bolt, is the form of sliding on the slope of lower brace; Slide plate on lower brace, in the tightening process of upper tightening bolt, is the form of sliding on the slope of upper brace.
Upper brace, lower brace are provided with reinforcement.
Inside upper brace, lower brace, sponge rubber bed course is set respectively.
The slope of upper slice slope and bottom sheet is all in the slope form of 45 °.
Connector of the present invention is made up of upper and lower two panels, diagonally opposing corner direction construction bolt.When bolt tightens up, just have a vertical clamping force, owing to being provided with ramp structure cleverly, vertical power is converted to and makes a concerted effort containing horizontal, so, the upper and lower two panels of brace, will produce four inside face convergent forces to tighten up rubber strip, this ensures that theres effectively being tightly connected of square tube and junction box.Connector not only may be used for the connection of square tube and junction box, and also may be used for the connection of square tube and square tube, degree of protection is higher than IP67.High performance rubber blanket is lined with within connecting, telescopicing performance is excellent, the connection of every connector, be exactly in fact one to be flexible coupling, while there is the function that mode expands with heat and contract with cold, also can install on uneven ground, at all can not affect its water resistance, possess the function of expansion joint simultaneously, do not need separately to join expansion joint again.

Embodiment
A kind of square tube hermetically sealed connector, comprises brace 3, lower brace 2; Upper brace to comprise slice and with upper slice vertical lateral plate, upper slice one end is slope 6 form, slope nearside is arranged installs the waist-shaped hole 15 of tightening bolt 12, and be slide plate 8 form with the lower end of upper slice vertical lateral plate, slide plate 8 nearside arranges the waist-shaped hole 16 installing time tightening bolt 10; Lower brace comprises bottom sheet and the lateral plate vertical with bottom sheet, one end of bottom sheet is slope 9 form, slope nearside arranges lower tightening bolt (or stud) 10, and the upper end of the lateral plate vertical with bottom sheet is slide plate 7 form, and slide plate 7 nearside arranges the hole 14 of installing tightening bolt 12; Upper brace, lower brace are connected by upper tightening bolt 12, lower tightening bolt 10 and corresponding attaching nut 13,11; Slide plate on upper brace, in the tightening process of lower tightening bolt, is the form of sliding on the slope of lower brace; Slide plate on lower brace, in the tightening process of upper tightening bolt, is the form of sliding on the slope of upper brace.
Upper brace, lower brace are respectively arranged with reinforcement 4,5.
Sponge rubber bed course 17,18 is set inside upper brace, lower brace respectively.
The slope of upper slice slope and bottom sheet is all in the slope form of 45 °.
Sponge rubber bed course 17, is pasted onto on the inwall of brace 3 in advance; Sponge rubber bed course 18 is pasted onto on the inwall of lower brace 2, two the involutory assembled rear tightening bolts 12 of brace 2 and 3 being up and down pasted with sponge rubber penetrate brace mounting hole 15 and penetrate the hole 14 of lower brace, finally be screwed into nut 13, upper and lower brace can vertically be stepped up mutually.Because the effect of upper brace 45 ° of slopes 6 and lower brace slide plate 7, the vertical force of mutually being stepped up by tightening bolt 12 and nut 13 be converted to horizontal direction and vertical direction with joint efforts.Meanwhile, penetrate upper brace mounting hole 16 by the lower tightening bolt 10 of lower brace, nut 11 is screwed into tightening bolt 10 under lower brace, owing to there being the effect of upper brace slide plate 8 and lower brace 45 ° of hypotenuses 9.The power of stepping up up and down of nut 11 and stud 10 forms the power of both direction and vertical clamping forces and horizontal-clamping power simultaneously, be there is clamping force, so reach the effect of water-tight like this by fitting square tube 1 four faces simultaneously.
In actual assembled, only need two interfaces of the square tube 1 be connected be placed on the centre position of the foam rubber layer 18 of lower brace 2, in split, brace 3. is set to the fastening method of diagonal due to bolt again, vertical clamping forces is produced when screwing tight, due to the effect of brace upper slide and slope, be vertical clamping force reaches square tube sealing object with regard to the tightening force being converted to four faces originally.
