Description

Technical Field

[0001] The utility model belongs to the technical field of line connection equipment, in particular to a quick connection joint for blasting lines. Background Art

[0002] Electronic detonators, also known as digital electronic detonators, digital detonators, or industrial digital electronic detonators, use electronic control modules to control the detonation process. In current electronic detonator blasting systems, each electronic detonator has its tail wire connected in parallel to the detonating busbar. Installation is accomplished through a junction box, typically by snapping several junction boxes onto the detonating busbar. The detonating busbar is made of copper-core metal wire. During installation, the outer sheath must be manually peeled to ensure the cutter contacts the copper core wire. The detonator and detonating busbar are then wound together.

[0003] After searching, a Chinese patent with publication number CN218548811U mentioned a detonator leg wire connection device, including a connection base and a connection plug inserted in the middle of the rear of the connection base. The inner lower surface of the connection base is symmetrically connected with fixed vertical plates, and a connection device is inserted above the inner surface of each fixed vertical plate. The middle of the left and right side surfaces of the connection base is connected with a connection support plate, and the inner surface of each connection support plate is evenly distributed in a horizontal row with several anti-slip rubber strips. The center of the rear surface of the connection plug is fixedly inserted with a connecting leg wire. The staff can connect them to each other without on-site peeling. After the connection is completed, the metal plate of the pin can be clamped to prevent loosening and poor contact. The operation is simple and convenient to use.

[0004] However, when the detonator leg wire is connected to the conductor (detonating busbar), both wires need to be stripped to expose the internal guide wire, and finally the two guide wires are twisted together and the detonation work can be achieved through the electronic controller. However, the existing wiring connection device cannot unify the work of the two, thereby reducing the work efficiency and the wiring effect of the device.

[0005] Therefore, those skilled in the art have proposed a blasting line quick-connect joint to solve the problems raised in the background art. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a quick connection joint for blasting lines to solve the problems of low wiring efficiency and imperfect device performance in the prior art.

[0007] A quick-connect joint for blasting lines comprises a line joint device body, a peeling mechanism for stripping the line during line jointing is provided on the inner side of the body, and a wire twisting mechanism for merging lines is provided on the outer side of the body.

[0008] Preferably, the peeling mechanism includes a closing component connected to the outside of the main body and a peeling component provided on the inside.

[0009] Preferably, the closing assembly includes a flip shaft and a cover plate, the cover plate is closed and connected to the outside of the flip shaft, and the inside of the cover plate is provided with a waterproof ring for providing waterproof and moisture-proof effects when closed.

[0010] Preferably, the peeling assembly includes a first tooth plate and a second tooth plate, and the first tooth plate and the second tooth plate are both fixed in grooves formed between the main body and the cover plate.

[0011] Preferably, the wire twisting mechanism includes a wire threading groove and a wire twisting assembly, and the wire threading groove is connected to one side of the wire twisting assembly.

[0012] Preferably, the twisting assembly includes a slider sleeved on the inner side of the wire threading groove for pulling and stripping to perform rotational twisting, and a clamping assembly for fixing the detonator leg wire and one end of the wire is provided on the outer side of the slider.

[0013] Preferably, the engaging assembly comprises a screw-tightening column and a torsion seat penetrating the inner side of the slider, and the torsion seat is welded to the outer end of the screw-tightening column.

[0014] Preferably, one side of the main body is provided with an insertion hole for arranging the stacked and raised stranded wire working wire group.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The utility model is provided with a stripping mechanism, which can strip the wire (detonating busbar) and the detonator leg wire at the same time when wiring the wire ends. Compared with the traditional working method of cutting the insulation skin on the outside of the wire group with stripping pliers, the stripping efficiency can be improved by the mutual engagement of the tooth plates inside the device. At the same time, it is more convenient for the staff to operate during stripping. Due to the different sizes of the detonator leg wire and the wire (detonating busbar), the tooth plates can also be used for stripping the detonator leg wire and the wire (detonating busbar) when they are clamped by the cover plate, thereby improving the stripping performance and applicability of the device.

[0017] 2. The utility model further improves the stripping and wiring performance of the device through the wire twisting mechanism, so that the detonator leg wire and the conductor (detonating busbar) can be more conveniently connected after stripping. At the same time, since the slider is arranged on the inner side of the wire threading groove, when it is pulled outward, the detonator leg wire and the conductor (detonating busbar) are clamped and cut by the tooth plate, and the outer insulating protective skin is stripped off. After the stripping work is completed, the wire is rotated and twisted, and the internal guide wire of the detonator leg wire and the conductor (detonating busbar) is used to complete the wiring work, which greatly improves the wiring efficiency and is convenient for the staff to operate.

[0024] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] As attached Figure 1 To the attached Figure 4 As shown:

[0026] Embodiment 1: The present invention provides a quick-connect joint for blasting lines, comprising a line joint device body 1 , a peeling mechanism 2 for stripping the line during jointing is provided on the inner side of the body 1 , and a wire twisting mechanism 3 for merging the lines is provided on the outer side of the body 1 .

[0027] When the stripping mechanism 2 is connecting the wire ends, the wire (detonating busbar) and the detonator leg wire can be stripped at the same time. Compared with the traditional working method of using stripping pliers to cut the insulation skin on the outside of the wire group, the one or two tooth plates provided inside the device are engaged with each other to improve the efficiency of the stripping work. At the same time, it is also more convenient for the staff to operate during stripping. Due to the different sizes of the detonator leg wire and the wire (detonating busbar), the cover plate 5 can also be used for stripping the detonator leg wire and the wire (detonating busbar) when clamped, thereby improving the stripping performance and applicability of the device.

[0028] The wire twisting mechanism 3 further improves the stripping and wiring performance of the device, so that the detonator leg wire and the conductor (detonating busbar) can be more conveniently wired after stripping. At the same time, since the slider 10 is arranged on the inner side of the wire threading groove 9, when pulled outward, the detonator leg wire and the conductor (detonating busbar) are clamped and cut by the tooth plate, and the outer insulating protective skin is stripped off. After the stripping work is completed, the wire is rotated and twisted, and the internal guide wire of the detonator leg wire and the conductor (detonating busbar) is used to complete the wiring work, which greatly improves the wiring work efficiency and is convenient for the staff to operate.

[0029] The peeling mechanism 2 includes a closing component connected to the outside of the main body 1 and a peeling component provided on the inside. The closing component includes a flip shaft 4 and a cover plate 5. The cover plate 5 is closed and connected to the outside of the flip shaft 4. The inside of the cover plate 5 is provided with a waterproof ring 6 for providing waterproof and moisture-proof effect when closed.

[0030] The waterproof ring 6 can effectively protect the detonator leg wire and the guide wire (detonating busbar) inside the device after stripping.

[0031] The peeling assembly includes a first tooth plate 7 and a second tooth plate 8 , and the first tooth plate 7 and the second tooth plate 8 are both fixed in grooves defined by the main body 1 and the cover plate 5 .

[0032] As can be seen from the above, when stripping, the cover plate 5 is opened along the outside of the flip axis 4, one end of the detonator leg wire is placed on the inside of the first tooth plate 7 and passed through the outside of the wire groove 9, and then one end of the wire (detonating busbar) is placed on the inside of the second tooth plate 8 and also passed through the outside of the wire groove 9, and then the twist seat 12 is twisted, and the screw column 11 is screwed to the inside of the slider 10. Through the continuous tightening of the screw column 11, the twist seat 12 fixes one end of the detonator leg wire and one end of the wire (detonating busbar) on the outside of the slider 10 and clamps them, and then the cover plate 5 is closed along the outside of the flip axis 4. By pulling the slider 10 outward, the detonator leg wire and the wire (detonating busbar) are clamped and cut by the first tooth plate 7 and the second tooth plate 8 respectively, and then the insulating protective skin on the outside of the detonator leg wire and the wire (detonating busbar) can be stripped off.

[0033] Embodiment 2: The wire twisting mechanism 3 includes a wire threading groove 9 and a wire twisting assembly. The wire threading groove 9 is connected to one side of the wire twisting assembly. The wire twisting assembly includes a slider 10 that is sleeved on the inner side of the wire threading groove 9 and is used to pull and rotate the wire after stripping. A locking assembly is provided on the outer side of the slider 10 for fixing the detonator leg wire and one end of the wire.

[0034] The engaging assembly includes a screw post 11 and a twist seat 12 passing through the inner side of the slider 10 . The twist seat 12 is welded to the outer end of the screw post 11 .

[0035] As can be seen from the above, after the detonator leg wire and the conductor (detonating busbar) are pulled outward by the slider 10 to complete the stripping work, they are then rotated and twisted along the inner side of the wire threading groove 9 to complete the wiring work of the detonator leg wire and the conductor (detonating busbar) internal guide wire.

[0036] One side of the main body 1 is provided with an insertion hole 13 for arranging a stacked and raised stranded wire working wire group.

[0037] The plug-in hole 13 can complete the stacking installation of the wiring device and has the working performance of convenient disassembly, thereby improving the working wire group of the twisted wire.

[0038] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
