Description

Technical Field

[0001] The utility model belongs to the field of penetration clips, and more specifically relates to a penetration clip which is convenient for splicing. Background Art

[0002] In order to ensure the normal use of solar photovoltaic components and brackets and prevent safety accidents such as lightning strikes, solar photovoltaic brackets must be grounded.

[0003] At present, the prior art uses a penetration clamp to achieve grounding of a solar photovoltaic bracket. The penetration clamp is installed on the track of the bracket, and the two are connected. Then, the penetration clamp is connected to a metal wire, and grounding is achieved through the metal wire.

[0004] In the prior art, in order to better ground the metal wire and to prevent the metal wire from sliding or loosening, which would result in the metal wire not being able to be better grounded, two penetration clips are usually used to splice the metal wire and then fix the metal wire. The two penetration clips need to be welded in advance, which is very troublesome. During installation, if the welded penetration clip bodies are not enough, the installation efficiency will be greatly affected. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a penetration clamp that is easy to splice, which has the advantage of being able to quickly assemble two penetration clamps.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A penetration clamp for convenient splicing, comprising a penetration clamp body, a wire groove for clamping a metal wire is arranged on the penetration clamp body, a threaded hole for fixing the wire is arranged on the penetration clamp body, a mounting hole for connecting a photovoltaic bracket is arranged on the penetration clamp body, a splicing hole is opened on one side wall of the penetration clamp body, a splicing joint is fixed on the other side wall, and a positioning component for pre-positioning the splicing joint is arranged in the splicing hole;

[0008] A first chamber is provided inside the penetration clamp body and on the left and right sides of the splicing hole. A rectangular groove connected to the chamber is provided on the inner wall of the splicing hole. The locking holes are symmetrically arranged on the two side walls of the splicing joint. A fixing component matching the locking hole is installed in the first chamber and the rectangular groove.

[0009] The advantage of this solution is at least that when two adjacent penetration clamp bodies need to be spliced, it is only necessary to extend the splicing joint into the splicing hole, pre-position the splicing joint through the positioning component in the splicing hole, and then rotate the fixing component to extend the fixing component into the lock hole, so as to fix the splicing joint in the splicing hole. This splicing method is fast and convenient, and the two penetration clamps can be quickly assembled.

[0010] The utility model is further configured as follows: the fixing assembly includes: a locking block, a rotating rod and a gear; a side wall of the locking block is provided with a rack meshing with the gear; the locking block is slidably installed in the rectangular hole; the gear is rotatably installed in the first chamber; one end of the rotating rod is fixed to the gear; the other end passes through the penetration clamp body and is rotatably connected to the penetration clamp body; a knob is installed at the end of the rotating rod that passes through the penetration clamp body.

[0011] The advantage of this solution is at least that when the rotating rod is rotated, the provided knob makes it more convenient to rotate the rotating rod.

[0012] The utility model is further configured as follows: the outer wall of the knob is surrounded by a knurled pattern.

[0013] The advantage of this solution is at least that the knurling pattern increases the friction between the knob and the finger, thereby preventing the hand from slipping when turning the knob.

[0014] The utility model is further configured as follows: a thread is arranged on the outer wall of the rotating rod near one end of the knob, and a nut is threadedly connected to the thread.

[0015] The advantage of this solution is at least that: the locking block with the rack is inserted into the locking hole through the rotating rod, the gear and the knob, and then the nut threaded on the rotating rod is screwed downward and the nut is made to fit tightly against the upper surface of the penetration clamp body. The rotating rod is fixed by locking the nut, thereby preventing the locking block from moving out of the locking hole during use of the spliced ​​penetration clamp bodies, causing the two adjacent penetration clamp bodies to loosen.

[0016] The utility model is further configured as follows: a guide rail is provided on the bottom surface of the rectangular hole, and a sliding block matched with the guide rail is fixed on the bottom of the locking block.

[0017] The advantage of this solution is at least that: through the cooperation of the guide rail and the slider, the locking block is more stable when moving in the rectangular hole, so that it can better extend into the locking hole.

[0018] The utility model is further configured as follows: the positioning assembly includes: a positioning pin with a semi-spherical end and a semi-spherical positioning hole, the positioning pin and the positioning hole are snap-connected, a circular hole is provided on the inner bottom surface of the splicing hole, a second chamber is provided in the penetration clamp body, the circular hole is communicated with the second chamber, the positioning pin is slidably installed in the circular hole and the second chamber, a spring is provided between one end of the positioning pin and the inner bottom surface of the second chamber, and the positioning hole is opened on the bottom surface of the splicing joint.

[0019] The advantages of this solution are at least that the positioning assembly plays a predetermined role when the splicing joint is inserted into the splicing hole. Since the positioning pin and the positioning hole are both semi-spherical, the spring will be compressed in the second chamber by extending and pulling out the splicing joint during splicing and disassembly, thereby making it easier for the positioning pin to enter and leave the positioning hole.

[0020] The utility model is further configured as follows: a convex block is provided on one side wall of the penetration clamp body, and a groove is provided on the other side wall.

[0021] The advantage of this solution is at least that the cooperation between the protrusion and the groove increases the connection strength between two adjacent penetration clip bodies.

[0022] The utility model is further configured as follows: a sealing cover is rotatably mounted on the opening of the splicing hole, and the sealing cover and the penetration clamp body are adsorbed together by a magnet.

[0023] The advantage of this solution is at least that the sealing cover is provided so that when the splicing hole is not in use, the sealing cover is adsorbed on the penetration clamp body by a magnet, thereby preventing debris and dust from entering the splicing hole.

[0024] In summary, the utility model has at least the following advantages:

[0025] 1. By setting the splicing joint, splicing hole, positioning component, locking hole and fixing component, when two adjacent penetration clamp bodies need to be spliced, it is only necessary to extend the splicing joint into the splicing hole, pre-position the splicing joint through the positioning component in the splicing hole, and then extend the fixing component into the locking hole by rotating the fixing component, so as to fix the splicing joint in the splicing hole. This splicing method is fast and convenient, and two penetration clamps can be quickly assembled;

[0026] 2. The knob makes it more convenient to rotate the rotating rod. The knurling pattern on the knob increases the friction between the knob and the finger, preventing the hand from slipping when turning the knob. The nut is set, and the locking block with the rack is inserted into the lock hole through the rotating rod, the gear and the knob, and then the nut threaded on the rotating rod is screwed down, and the nut is made to fit tightly against the upper surface of the penetration clamp body. The rotating rod is fixed by tightening the nut, preventing the locking block from moving out of the lock hole during the use of the spliced ​​penetration clamp body, causing the adjacent two penetration clamp bodies to become loose;

[0027] 3. By setting the guide rail and the slider, the cooperation of the guide rail and the slider makes the lock block more stable when moving in the rectangular hole, so that it can be better inserted into the lock hole; the positioning pin and the positioning hole are both set in a semi-spherical shape, and the spring will be compressed in the second chamber by extending and pulling out the splicing joint during splicing and disassembly, so that the positioning pin can enter and leave the positioning hole more conveniently; by setting the protrusion and the groove, the connection strength between the two adjacent penetration clamp bodies is increased, and the setting of the sealing cover makes the sealing cover adsorbed on the penetration clamp body by a magnet when the splicing hole is not in use, so as to prevent debris and dust from entering the splicing hole.

[0039] The fixing assembly 11 includes: a locking block 1101, a rotating rod 1102 and a gear 1103. A rack 1104 meshing with the gear 1103 is provided on one side wall of the locking block 1101. The locking block 1101 is slidably installed in the rectangular hole. The locking holes 10 are symmetrically arranged on the two side walls of the splicing joint 6. The gear 1103 is rotatably installed in the first chamber 8. One end of the rotating rod 1102 is fixed on the gear 1103, and the other end passes through the penetrating clamp body 1 and is rotatably connected to the penetrating clamp body 1. A knob 12 is installed at the end of the rotating rod 1102 passing through the penetrating clamp body 1. The outer wall of the knob 12 is surrounded by a knurled pattern. Figure 3 As shown (refer to Figure 5), further, a guide rail 14 is provided on the bottom surface of the rectangular hole, and a slider 15 cooperating with the guide rail 14 is fixed to the bottom of the locking block 1101. Through the cooperation of the guide rail 14 and the slider 15, the locking block 1101 is more stable when moving in the rectangular hole, so that it can better extend into the locking hole 10.

[0040] like Figure 3 , Figure 4 As shown (refer to Figure 7 ), in order to increase the connection strength between two adjacent penetration clamp bodies 1, a protrusion 19 is provided on one side wall of the penetration clamp body 1, and a groove 20 is provided on the other side wall. In some embodiments, in order to prevent the locking block 1101 from moving out of the lock hole 10 during use of the spliced ​​penetration clamp body 1, a thread is provided on the outer wall of the rotating rod 1102 at one end close to the knob 12, and a nut 13 is threadedly connected to the thread. After the locking block 1101 with the rack 1104 is inserted into the lock hole 10, the nut 13 threadedly connected on the rotating rod 1102 is screwed downward, and the nut 13 is tightly attached to the upper surface of the penetration clamp body 1, and the rotating rod 1102 is fixed by locking the nut 13.

[0041] like Figure 6 , Figure 7 As shown, the positioning assembly 7 includes: a positioning pin 701 with a semi-spherical end and a semi-spherical positioning hole 702, the positioning pin 701 and the positioning hole 702 are snap-fitted and connected, a circular hole 16 is provided on the inner bottom surface of the splicing hole 5, a second chamber 17 is provided in the penetration clamp body 1, the circular hole 16 is communicated with the second chamber 17, the positioning pin 701 is slidably installed in the circular hole 16 and the second chamber 17, a spring 18 is provided between one end of the positioning pin 701 and the inner bottom surface of the second chamber 17, and the positioning hole 702 is opened on the bottom surface of the splicing joint 6.

[0042] The working process and beneficial effects of the utility model are as follows:

[0043] When it is necessary to splice two adjacent penetration clamp bodies 1, first open the sealing cover 21, then extend the splicing joint 6 into the splicing hole 5, and extend the protrusion 19 into the groove 20. The locating pin 701 arranged in the splicing hole 5 compresses the spring 18 under the extrusion of the splicing joint 6, thereby moving the locating pin 701 into the second chamber 17. When the locating hole 702 and the locating pin 701 are coaxial, the locating pin 701 is extended into the locating hole 702 under the reaction force of the spring 18, thereby pre-positioning the splicing joint 6.

[0044] By rotating the knob 12, the knob 12 drives the rotating rod 1102 and the gear 1103 to rotate. At this time, the rack 1104 meshing with the gear 1103 drives the locking block 1101 to slide in the rectangular hole and the first chamber 8. Through the cooperation of the guide rail 14 and the slider 15, the locking block 1101 is more stable when moving in the rectangular hole, so that the locking block 1101 can be better extended into the locking hole 10 on the splicing joint 6, so as to fix the splicing joint 6 in the splicing hole 5. This splicing method is fast and convenient, and the two penetration clamps can be quickly assembled.

[0045] After the fixing assembly 11 is fixed, the nut 13 threadedly connected to the rotating rod 1102 is screwed downward, and the nut 13 is made to fit tightly against the upper surface of the penetration clamp body 1. The rotating rod 1102 is fixed by locking the nut 13 to prevent the locking block 1101 from moving out of the locking hole 10 during use of the spliced ​​penetration clamp body 1, causing the two adjacent penetration clamp bodies 1 to become loose.
