Description

Technical Field

[0001] This invention relates to the field of waterproof wire clip technology, and more particularly to a waterproof wire clip for detonators. Background Technology

[0002] Detonators are devices used to detonate explosives. During detonation, to ensure the stability of the connection between the detonating wires, clamps are typically used to secure the connection. However, existing clamps have poor waterproofing performance, making detonators susceptible to water ingress in humid environments. This can lead to connection failure of the detonating wires and pose a safety hazard, preventing proper detonation. Therefore, existing clamps require internal sealing materials for waterproofing, making their use more cumbersome and inefficient. To address this, we propose a waterproof clamp for detonators. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a waterproof wire clip for detonators.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a waterproof clamp for detonators, comprising a lower clamp body, an upper clamp body mounted on the upper surface of the lower clamp body, a first sealing strip provided along the edge of the upper surface of the lower clamp body, a second sealing groove provided along the edge of the lower surface of the upper clamp body, the first sealing strip being embedded in the second sealing groove, a first sealing groove provided on the inner bottom surface of the lower clamp body, a second sealing strip provided on the inner top surface of the upper clamp body, the second sealing strip being embedded in the first sealing groove, and partition grooves provided between the first sealing strip and the first sealing groove, as well as between the second sealing groove and the second sealing strip.

[0005] Both the lower and upper card bodies have a semi-circular fixing ring at the center of the front end of their outer surfaces. The lower card body has a support plate at the center of its inner bottom surface. The support plate has a fixing frame on both sides of its upper surface, and a partition on both sides of its upper surface. The inner surfaces of both sets of partitions have support frames.

[0006] The upper card body has isolation frames staggered on both sides of the middle of the inner top surface. The isolation frames are inserted and sleeved onto the outer surface of the fixed frame. The upper card body has sealing caps that match the partitions on both sides of the middle of the inner top surface.

[0007] The upper and lower clamping bodies are secured with detonator leads via a fixing ring. The detonator leads have a first sub-wire and a second sub-wire inside. The first sub-wire and the second sub-wire are respectively secured to a support frame inside the partition. The other end of the first sub-wire and the second sub-wire are each provided with an adapter block. The adapter block is inserted into the fixing frame. The outer sides of the adapter block are provided with branch lines, and the other end of the branch lines extends outward through the lower clamping body.

[0008] Preferably, the lower card body and the upper card body are both provided with a semi-circular fixing ear at the middle of the rear end of their outer surfaces, and the outer surfaces of the fixing ears are jointly fitted with a second locking screw ring.

[0009] Preferably, both ends of the inner surface of the fixing ring are provided with protruding sealing rings, and the outer surface of the fixing ring is fitted with a first locking screw ring.

[0010] Preferably, the four corners of the pallet are inclined, and the upper surface of the pallet is provided with positioning cylinders at the four corners.

[0011] Preferably, the inner surface of the fixed frame is provided with several limiting grooves on both sides, and the outer surface of the fixed frame is provided with several limiting blocks in the shape of "T" protrusions on both sides.

[0012] Preferably, each of the four corners of the inner top surface of the upper card body is provided with a positioning rod, and the positioning rod is inserted into the positioning cylinder.

[0013] Preferably, the outer surface of the isolation frame is provided with a plurality of limiting ports on both sides, and the limiting ports are inserted into the outer surface of the limiting block.

[0014] Preferably, the outer surface of the detonator lead wire is provided with an isolation groove, which fits into the sealing ring.

[0015] Preferably, mounting blocks are provided on both sides of the outer surface of the adapter block, and the mounting blocks are embedded in the limiting groove.

[0016] Preferably, the second sealing strip and the outer surfaces of the isolation frame are provided with openings that match the branch line.

[0017] Compared with the prior art, the present invention has the following beneficial effects: When using wire clips to fix the connection of the detonator wire, the connection of this waterproof wire clip is interlocked and equipped with partitions, which can improve the sealing of the connection and help avoid water ingress when the wire clip is used in a humid environment. At the same time, it can provide suspended isolation protection for the detonator wire inside, which can help avoid the failure of the detonator wire connection caused by water ingress. This helps reduce the safety hazards of using detonators in humid environments. Moreover, the sealing structure of the entire waterproof wire clip is integrated with the wire clip, avoiding the need to add sealing materials inside the traditional wire clip for waterproofing. This simplifies the waterproofing process of the wire clip and improves work efficiency. Attached Figure Description

[0020] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. Example 1

[0021] As attached Figure 1-7 The waterproof clamp for detonators shown includes a lower clamp body 1, an upper clamp body 2 mounted on the upper surface of the lower clamp body 1, a first sealing strip 3 provided along the edge of the upper surface of the lower clamp body 1, a second sealing groove 5 provided along the edge of the lower surface of the upper clamp body 2, the first sealing strip 3 embedded in the second sealing groove 5, a first sealing groove 4 provided on the inner bottom surface of the lower clamp body 1, a second sealing strip 6 provided on the inner top surface of the upper clamp body 2, the second sealing strip 6 embedded in the first sealing groove 4, and a partition groove 7 provided between the first sealing strip 3 and the first sealing groove 4, and between the second sealing groove 5 and the second sealing strip 6.

[0022] Both the lower clamping body 1 and the upper clamping body 2 have semi-circular fixing ears 8 at the middle of their rear ends on their outer surfaces. The outer surfaces of the fixing ears 8 are fitted with a second locking screw ring 12. Both the lower clamping body 1 and the upper clamping body 2 have semi-arc-shaped fixing rings 9 at the middle of their front ends on their outer surfaces. Both ends of the inner surface of the fixing rings 9 have protruding sealing rings 10. The outer surfaces of the fixing rings 9 are fitted with a first locking screw ring 11. The lower clamping body 1 has a support plate 13 at the middle of its inner bottom surface. The four corner edges of the support plate 13 are inclined. The four corners of the upper surface of the support plate 13 have positioning cylinders 14. The upper surface of the support plate 13 has a fixed frame 15 staggered on both sides on its middle side. The inner surface of the fixed frame 15 has several limiting grooves 16 on both sides. The outer surface of the fixed frame 15 has several T-shaped protruding limiting blocks 17 on both sides. The upper surface of the support plate 13 has partitions 18 on both sides. The inner surfaces of the two sets of partitions 18 have support frames 19.

[0023] The upper card body 2 has positioning rods 20 at each of the four corners of its inner top surface. The positioning rods 20 are inserted into the positioning cylinder 14. The upper card body 2 has isolation frames 21 staggered on both sides of the middle of its inner top surface. The isolation frames 21 are inserted and sleeved onto the outer surface of the fixed frame 15. The outer surface of the isolation frames 21 has several limiting holes 22 on both sides. The limiting holes 22 are inserted into the outer surface of the limiting block 17. The upper card body 2 has sealing caps 23 that match the partition plate 18 on both sides of the middle of its inner top surface.

[0024] The upper clamping body 2 and the lower clamping body 1 are clamped together by the fixing ring 9 to install the detonator lead wire 24. The outer surface of the detonator lead wire 24 is extruded with an isolation groove 25, which fits with the sealing ring 10. The interior of the detonator lead wire 24 is provided with a first sub-wire 26 and a second sub-wire 27 respectively. The first sub-wire 26 and the second sub-wire 27 are respectively clamped to the support frame 19 provided in the partition plate 18. The other end of the first sub-wire 26 and the second sub-wire 27 is provided with an adapter block 28, which is inserted into the fixing frame 15. The outer surface of the adapter block 28 is provided with mounting blocks 29 on both sides, which are embedded in the limiting groove 16. The outer sides of the adapter block 28 are provided with branch lines 30, the other end of which extends outward through the lower clamping body 1. The outer surfaces of the second sealing strip 6 and the isolation frame 21 are provided with openings that match the branch lines 30.

[0025] During operation, the detonator lead wire 24 can first be clamped into the fixing ring 9 that is commonly provided between the lower clamping body 1 and the upper clamping body 2. The first sub-wire 26 and the second sub-wire 27 are respectively fixed to the support frame 19 provided in the interval between the corresponding partitions 18. At this time, the adapter block 28 provided at the end of the first sub-wire 26 and the second sub-wire 27 can be clamped and installed into the fixing frame 15 through the mounting block 29. At this time, the mounting block 29 can be embedded into the limiting groove 16 opened on the inner surface of the fixing frame 15 for clamping and fixing, thereby completing the clamping and fixing connection between the detonator lead wire 24 and the lower clamping body 1. At this time, the branch wire 30 of the detonator detonating wire can be extended through the opening opened on the lower clamping body 1 and fixedly connected to the adapter block 28, thereby completing the connection between the detonator and the detonator lead wire 24.

[0026] After the detonator and detonator lead 24 are connected and fixed, the positioning rods 20 at the four corners of the top surface of the upper clamping body 2 and the positioning cylinders 14 at the four corners of the upper surface of the support plate 13 can be aligned and inserted. At this time, the upper clamping body 2 and the lower clamping body 1 can be connected. The first locking ring 11 and the second locking ring 12 are respectively fitted onto the outer surfaces of the fixing ring 9 and the fixing ear 8 that are provided at the middle of both ends of the upper clamping body 2 and the lower clamping body 1. At this time, the connection between the upper clamping body 2 and the lower clamping body 1 is tighter. After the upper clamping body 2 and the lower clamping body 1 are connected, the second sealing strip 6 on the lower surface of the upper clamping body 2 will be embedded into the first sealing groove 4 opened on the upper surface of the lower clamping body 1. At the same time, the first sealing strip 3 on the upper surface of the lower clamping body 1 will be embedded into the second sealing groove 5 opened on the lower surface of the upper clamping body 2. Inside, since the second sealing strip 6 is embedded in the first sealing groove 4 and the first sealing strip 3 is embedded in the second sealing groove 5 in an alternating manner, the sealing performance of the connection between the upper card body 2 and the lower card body 1 can be improved. This helps to avoid water ingress when the wire clip is used in a humid environment. Secondly, a partition groove 7 is provided between the intervals where the second sealing strip 6 is embedded in the first sealing groove 4 and the first sealing strip 3 is embedded in the second sealing groove 5 in an alternating manner. The partition groove 7 can isolate the connection between the upper card body 2 and the lower card body 1. When water seeps into the wire clip from the connection between the upper card body 2 and the lower card body 1, the seeping water will be blocked by the partition groove 7, thus preventing it from entering the interior of the wire clip and further improving the waterproof effect of the wire clip.

[0027] After the upper card body 2 and the lower card body 1 are connected, the isolation frame 21 on the inner bottom surface of the upper card body 2 will be fitted onto the outer surface of the fixing frame 15 through the limiting port 22. At the same time, the sealing cover 23 on the inner bottom surface of the upper card body 2 will cover the upper surface of the partition 18. In this case, the isolation frame 21, the fixing frame 15, and the sealing cover 23, along with the partition 18, can provide double isolation protection for the first sub-wire 26, the second sub-wire 27, and the adapter block 28 at their ends. With the support of the support frame 19, the first sub-wire 26, the second sub-wire 27, and the adapter block 28 at their ends are suspended in the air and not in contact with the inner surface of the wire clamp. Contact is made, and the tray 13 set on the inner bottom surface of the lower clamp 1, with its inclined corners, can drain the seepage water in the case of water seepage inside the clamp. The seepage water can be drained to the lower part of the inner bottom surface of the lower clamp 1 to reduce the spread rate of the seepage water, thereby slowing down the contact speed between the seepage water and the detonator wire connection and thus providing time for detonation. This is beneficial for providing isolated waterproof protection for the first sub-wire 26 and the second sub-wire 27 and the adapter block 28 set at their ends, thereby avoiding the problem of detonator wire connection failure caused by water seepage inside the clamp, and reducing the safety hazards of using detonators in humid and watery environments.

[0028] In summary, this waterproof cable clamp helps prevent water ingress when used in humid or wet environments. It also provides suspended isolation protection for the detonator wire inside, preventing connection failure in the event of water ingress. Furthermore, the entire waterproof cable clamp's sealing structure is integrated with the clamp itself, eliminating the need for internal sealing materials as required by traditional cable clamps.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
