Description

Pin hole type anti-drop square tube sealing connector

Technical Field

The utility model belongs to the technical field of square pipe connection, and particularly relates to a pin hole type anti-falling square pipe sealing connector.

Background

Generally, in cities of the first subway, at least the tank boxes of the AFC ground wiring of the first subway are filled with water, and the cable is not uncommon to be immersed in the water. The subway owners and engineering units with experience training have paid great attention to the waterproof problem of the AFC ground wiring groove and the box.

Initially, subway AFC floor wiring systems were laid using conventional floor socket slots, boxes. Since the waterproof requirements of conventional ground wiring systems are not high, the protection level is generally within IP 44. After the domestic multiple AFC systems are used, the following steps are found: a large amount of groundwater is reserved in the tank box, a considerable part of cables are soaked in the groundwater, and certainly, the outer skin of the cables is damaged in the construction process, so that the electric leakage condition is necessarily present.

In order to solve the problem of water leakage of the subway AFC wiring system groove and box, the protection level of the groove and box, namely the water sealing performance, is required to be improved. By demonstration, the protection grade generally reaches IP67 to meet the waterproof requirement. Therefore, some subway AFC ground wiring in China solves the problem by adopting a field welding method because of water resistance. Because the common steel plate is subjected to surface treatment (the corrosion resistance of the steel is improved by adopting a hot galvanizing method), the common steel plate is not suitable for being welded on site. Because the on-site welding can damage the anticorrosive coating on the surface, the welding position can be corroded and damaged in a short time, or the phenomenon of water leakage is easily caused, based on the reasons, the domestic multi-subway AFC ground wiring system adopts stainless steel materials to form grooves and boxes, and then the grooves and boxes are assembled and welded on site, so that the waterproof capacity of the grooves and the boxes is improved. Of course, this also plays a role in some waterproofing, but increases the difficulty of construction on site. And the investment is multiplied. Open fire can be generated due to field welding, and the potential safety hazard of fire is increased.

Some existing AFC waterproof sealing connectors generally adopt two connecting sheets with different structures or the same structure, and then the connecting sheets are oppositely connected and fixed through bolts. But in the subsequent use process, the wire groove box is generally subjected to external impact and other conditions, so that the wire groove box transversely moves in the laying direction, and the sealing waterproof performance of the wire groove is affected.

The utility model will now be described in further detail by way of specific examples of embodiments in connection with the accompanying drawings.

Examples

As shown in fig. 1, a pinhole type anti-drop square tube sealing connector comprises a first wire groove 1 and a second wire groove 2 which are connected with each other, wherein a connector 3 is installed at the joint of the first wire groove 1 and the second wire groove 2, a positioning hole 5 is installed on the connector 3, and the positioning hole 5 is matched with a positioning pin 6 on the wire groove.

In the pin hole type anti-drop square pipe sealing connector in the embodiment, the locating pin 6 passes through the locating hole 5 to be connected in an adapting mode, so that the wire groove is prevented from traversing in the length direction, and the sealing performance of the wire groove is guaranteed.

Examples

In this embodiment, as shown in fig. 1, the positioning hole 5 is located at a side portion of the connector 3, that is, a side portion of the wire slot, and is not an upper surface, so that normal construction or laying above the wire slot is not affected.

In this embodiment, the positioning hole 5 may be mounted on one of the upper connector or the lower connector. However, in order to realize the protection in all directions, prevent to take place the disjoint, can select and all install locating hole 5 on top connector and the below connector, the anticreep function can all be realized to two lateral parts of wire casing like this, has improved holistic sealing performance greatly. The combination symmetry of both sides locating hole 5 and locating pin 6 realizes dual protection, improves shock resistance, and no matter from which direction takes place to strike like this, all can protect two wire casings, prevents the condition of sideslip.

In this embodiment, the number of the positioning holes 5 on the same side may be one, and when one positioning hole is provided, the positioning hole 5 is located at a position close to the slot 4, but at a position avoiding the slot 4. Meanwhile, in order to further prevent the disconnection and improve the overall protection performance, the number of the positioning holes 5 on the same side can be two or more. When the number of the positioning holes on the same side is two, as shown in fig. 1 and 2, the two positioning holes are symmetrically distributed on two sides of the slot 4 and are respectively equal to the space between the slot 4 and the positioning pin 6, and the space between the slot 4 and the positioning pin 6 is equal to the space between the slot 4.

In this embodiment, the positioning hole 5 is a kidney-shaped hole. The positioning holes 5 are waist-shaped holes, so that when the connector is installed, certain position difference between the positioning holes and the positioning pins 6 is allowed, and the construction is facilitated.

Examples

In this embodiment, similar to the arrangement structure of the positioning holes, the positioning pins 6 may be selectively fixed (welded or otherwise fixed) on the first wire slot 1 or the second wire slot 2, or may be simultaneously installed on the first wire slot 1 and the second wire slot 2, where the positioning pins 6 are arranged and the number of the positioning pins are adapted to the positioning holes 5.

Further, as shown in fig. 2, when the positioning pins 6 are fixed on the first wire slot 1 and the second wire slot 2 at the same time, the positioning pins 6 on the respective wire slots are equidistant from the wire slot slit 4.

In this embodiment, the positioning pin 6 not only can abut against the positioning hole 5, but also can perform positioning. In the actual installation process, the slot 4 is positioned at the center of the connector, so that good sealing performance can be ensured. However, in the actual installation process, sometimes the position of the slot 4 is not centered, so that the sealing performance is affected after the installation. Thus, if the installation is carried out according to the position of the fixed locating pin 6, the position of the slot 4 of the wire groove can be ensured to be positioned at the center of the connector, thereby realizing good sealing performance and ensuring sealing effect.

In this embodiment, in order not to affect the construction and laying of the side portion of the trunking, the length of the locating pin 6 is 5-20mm.

Examples

The pin-hole type anti-slip square tube sealing connector has the same structure as that in the embodiment 3, except that the positioning pin 6 is not fixedly connected, but can be connected in a threaded manner. The fixing mode of threaded connection is adopted, the positioning pin 6 is not required to be fixed with the wire groove in advance, a plurality of threaded holes can be formed in the side wall of the wire groove, and then the positioning pin 6 is fixed on the wire groove in a threaded mode.

Or the positioning pin 6 can be welded or press-riveted with the wire slot, and the positioning pin 6 can be made of a metal material or a nonmetal material. The welding or crimping mode is firm in connection, the abutting effect can be achieved as well, lateral movement is prevented, and sealing performance is improved.

The connector in the above embodiment adopts the connector structure of the prior art chinese laid-open patent CN103151737B or CN 213990078U.
