Detailed Description
Embodiment 1, this embodiment is an apparatus for connecting a wire chase and a wire chase, and as shown in fig. 2, this apparatus is configured such that a ground end of a wire chase 1 is connected to one end of another wire chase 1, a lapel 2, a snap-in piece 4, and the like are used in addition to a screw 3, and the two wire chases are connected at a connection point of the wire chase 1 and the wire chase 1 by the lapel 2 and the snap-in piece 4.
In this embodiment, the lapels 2 are combined with the screws 3 in advance, as shown in fig. 4, 5 and 6, the screws 3 are screwed into the corresponding positions of the lapels 2, and the gap between the screw caps and the lapels is kept to be larger than the thickness of the middle wall of the trunking 1.
The clamping sheet 4 is a copper waterline sheet, a clamping opening position 4-1 for clamping the screw rod is arranged on one side of the clamping sheet, in practice, the opening position 4-1 is an opening with a small outer part and a large inner part, the outer end of the opening position 4-1 only needs to be slightly larger than the diameter of the screw rod, the inner part can be larger than the opening part, but cannot be larger than the screw cap, namely, the screw cap cannot come out from the inner part of the opening position 4-1.
The assembly process of the device for connecting a wire chase and a wire chase of this embodiment is as follows:
step 1, screwing a screw into the lapel to ensure that a gap reserved between a screw cap and the lapel is wider than the thickness of the side wall of the wire groove; as shown in fig. 4, 5, 6.
Step 2, enabling the lapel to be close to one side of the side wall of the wire slot, enabling the screw cap to penetrate out of the middle of the locking hole in the side wall, and then moving towards one end of the locking hole; here, on the wire casing lateral wall, two wire casing junctions set up the connecting hole, utilize to refute piece and joint piece and connect two wire casings here, the connecting hole needs the screw cap to get into, but will block after removing, can not come out. Therefore, in this embodiment, the locking hole is adopted, and the shape is like a keyhole, the middle is larger, the two sides are smaller, in practice, the mode of arranging the small holes on the side surfaces of the large hole can also be adopted, the small holes comprise a pair of holes symmetrically arranged on the two sides of the large hole, and the small holes and the large hole form a transverse locking hole. Similarly, the small holes comprise a pair of holes which are symmetrically arranged above and below the large hole, and the small holes and the large hole form vertical locking holes. Of course, only one small hole may be provided on the side of the large hole. The following requirements are made for the large and small pores: the diameter of the large hole is larger than that of the screw cap, the diameter of the small hole is smaller than that of the screw cap and larger than that of the screw rod, and the screw rod can slide into the small hole from the large hole. In practice, the diameter of the large hole is about 14mm, the diameter of the small holes on two sides is 6mm, and the length of the whole lock hole is about 22 mm.
And 3, clamping the clamping sheet between the screw cap and the side wall from the other side of the side wall, and locking the screw.
So that the raceway is connected to the raceway as shown in figure 3.
Refute the piece in this embodiment and can follow the wire casing inside and press close to the wire casing lateral wall, the joint piece is between screw cap and the wire casing lateral wall is gone into to the outside card of wire casing, as shown in figure 3. Similarly, refute the piece and can follow the wire casing outside and press close to the wire casing lateral wall, the joint piece is inside the wire casing card go into between screw cap and the wire casing lateral wall. The clamping sheet is a copper water line sheet, and a clamping groove extending from one side to the middle is formed in the copper water line sheet.
In this embodiment:
the connecting hole on the wire groove is in a hole shape formed by matching a large round hole at the central part and small holes at two sides, and can be called as a lock hole because the connecting hole is similar to a key hole. The big hole part allows the screw cap to be easily inserted in alignment, and the small hole part clamps the screw cap (screw head) to prevent the screw cap from loosening and falling off.
The opening type copper waterline piece is provided with a special opening position, so that the copper waterline piece can be placed into a screw from the upper part for direct positioning after the wire groove is formed in the refute piece, and the copper waterline piece does not need to be aligned with the wire groove hole and the refute piece hole for positioning during assembly.
Refute the piece in advance and the screw assembly is very convenient, and the assembler can twist all screws into in advance refute on the piece, prevents to aim at wire casing, copper water line piece assembly inconvenience.
The invention has the following advantages: the wiring groove connection assembly is facilitated, the assembly time is reduced, and multiple times of mutual alignment and complex assembly sequence are reduced. Because most of the wire grooves are connected at the height of 2-3 meters from the ground, assembly personnel need to assemble on the workbench, the invention reduces the assembly time, reduces the time for the personnel to stay on the workbench, and is also beneficial to reducing the possibility of accidents.
In other embodiments, the number of the locking holes 1-1 on both sides of the trunking 1 can be set as desired, as shown in fig. 7, 8 and 9. The distance between the lock holes 1-1 is also set according to the requirement, as shown in fig. 10, a schematic diagram is set for the number of different lock holes 1-1 and the distance between them.
