[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Specific examples are given below.

[0028] See also Figure 1 - Figure 7 The utility model provides a photovoltaic panel connector, including a connector body 1, wherein a photovoltaic panel support frame 11 is arranged at the bottom of the outer side wall of the connector body 1; a pair of sliders 12 are in sliding contact with the inner side wall of the connector body 1; a slide column 13 is fixedly connected to the outer side wall of the slider 12; the slide column 13 slides with the connector body 1; the slide column 13 cannot be separated from the connector body 1; a fixing ring 14 is fixedly connected to the outer side wall of the slider 12; a pair of first support columns 15 are fixedly connected to the top of the outer side wall of the photovoltaic panel support frame 11; the top of the outer side wall of the first support column 15 is fixedly connected to A first connecting column 16; a positive limit ring 17 is fixedly connected to the top of the outer side wall of the first connecting column 16; the positive limit ring 17 is in sliding contact with the fixed ring 14; a reverse limit ring 18 is in sliding contact with the bottom of the outer side wall of the first connecting column 16; a plurality of first springs 19 are fixedly connected to the inner side wall of the fixed ring 14; a pair of first dampers 10 are fixedly connected to the inner side wall of the fixed ring 14; a limit block 101 is fixedly connected to the outer side wall of the first damper 10; a first spring 19 is fixedly connected to the outer side wall of the limit block 101; the limit block 101 is in contact with the positive limit ring 17. The connector body 1 is pressed downward, and the fixing ring 14 moves downward. The limit block 101 contacts the positive limit ring 17. When the connector body 1 moves to a certain position, the limit block 101 is squeezed, and then the limit block 101 moves until the limit block 101 is located below the positive limit ring 17. When the connector body 1 is pulled upward, the limit block 101 cannot be separated from the photovoltaic panel support frame 11 due to the restriction of the positive limit ring 17 on the limit block 101. When the fixing ring 14 is pressed downward to make the limit block 101 located at the reverse limit ring 18, the limit block 101 is moved downward. When the connector 1 is pulled downward, the limit block 101 pulls the reverse limit ring 18 to move until the reverse limit ring 18 contacts the forward limit ring 17, and continues to pull upward. The connector body 1 can be separated from the photovoltaic panel support frame 11. By setting the limit block 101, the forward limit ring 17 and the reverse limit ring 18, the probability of the connector body 1 being separated from the device when it is pulled due to accidents during the operation of the equipment is reduced, the stability of the equipment is increased, and the time spent by the staff to fix the connector body 1 is reduced, which facilitates the staff to install the equipment.

[0029] Further, such as Figure 1 , Figure 2 and Figure 3 As shown, the first support column 15 is fixedly connected to the outer wall of the first support column 15; a plurality of telescopic rods 21 are fixedly connected to the top of the outer wall of the first support ring 2; a plurality of second springs 22 are fixedly connected to the top of the outer wall; a second support ring 23 is fixedly connected to the outer wall of the telescopic rod 21; a second spring 22 is fixedly connected to the bottom of the outer wall of the second support ring 23; the second support ring 23 is in contact with the fixing ring 14; a third spring 24 is fixedly connected to the inner wall of the connector body 1; a second damper 25 is fixedly connected to the inner wall of the connector body 1; and a slider 12 is fixedly connected to the outer wall of the second damper 25. The fixing ring 14 is pressed to make it contact with the second support ring 23. At this time, the telescopic rod 21 and the second spring 22 are compressed under pressure. The third spring 24 and the second damper 25 make the movement of the slider 12 more stable. When the fixing ring 14 is released, the second spring 22 and the telescopic rod 21 will quickly return to their initial positions, exerting a certain upward force on the fixing ring 14 to assist the fixing ring 14 to disengage from the positive limit ring 17. By setting the second spring 22 and the telescopic rod 21, when the staff needs to remove the connector body 1, they can continue to press the fixing ring 14 to make the fixing ring 14 pop out, thereby reducing the difficulty for the staff to remove the fixing ring 14 and enabling the staff to complete the disassembly of the connector body 1 in a short time, making it convenient for the staff to use the equipment.

[0030] Further, such as Figure 6 As shown, a connecting rope 3 is fixedly connected to the bottom of the outer wall of the reverse limit ring 18; the connecting rope 3 is in sliding contact with the inner wall of the first support column 15; a connecting ring 31 is fixedly connected to the outer wall of the connecting rope 3; the connecting ring 31 is in sliding contact with the first support column 15; a plurality of fourth springs 32 are fixedly connected to the inner wall of the first support column 15; a connecting ring 31 is fixedly connected to the outer wall of the fourth spring 32; a plurality of sliding grooves 33 are provided on the inner wall of the first support column 15; the sliding groove 33 has the same diameter as the connecting ring 31; the connecting ring 31 cannot be separated from the sliding groove 33. The fourth spring 32 pulls the connecting ring 31, thereby applying a force to the reverse limit ring 18 to move it closer to the first support column 15. When the limit block 101 is not in contact with the reverse limit ring 18, the reverse limit ring 18 remains in contact with the first support column 15. After the limit block 101 pushes the reverse limit ring 18 to move upward, the fourth spring 32 pulls the reverse limit ring 18 back to its initial position. By setting the connecting rope 3 and the fourth spring 32, when the equipment is installed in a non-vertical position, the reverse limit ring 18 can be prevented from sliding due to gravity, thereby preventing it from fitting with the forward limit ring 17. The situation in which the limit block 101 is difficult to contact the bottom of the forward limit ring 17 due to the movement of the position of the reverse limit ring 18 can be reduced, thereby reducing the failure rate of the equipment.

[0031] Further, such as Figure 1 and Figure 2 As shown, a pair of support plates 4 are fixedly connected to the outer wall of the connector body 1; a third damper 41 is fixedly connected to the bottom of the outer wall of the support plate 4; a fifth spring 42 is fixedly connected to the bottom of the outer wall of the support plate 4; a contact plate 43 is fixedly connected to the outer wall of the third damper 41; and the contact plate 43 is in contact with the fixing ring 14. When the device is working, an upward elastic force is applied to the fixing ring 14, and the third damper 41 and the fifth spring 42 absorb the excessive elastic force of the fixing ring 14. By setting the third damper 41 and the fifth spring 42, the impact force of the slider 12 on the connector body 1 when the fixing ring 14 is bounced is reduced, and the bending and breaking of the slider 12 due to the impact is reduced, thereby increasing the stability of the device.

[0032] Further, such as Figure 1 As shown, the side wall of the fixing ring 14 is in sliding contact with a sealing plate 5; the sealing plate 5 can be detached from the fixing ring 14. The sealing plate 5 is pushed to fill the hollow position inside the fixing ring 14. The provided sealing plate 5 can reduce the situation where dust and impurities enter the inside of the fixing ring 14 when the equipment is in use, which affects the normal operation of the equipment. When the equipment has not been used for a long time and the inner wall of the fixing ring 14 needs to be cleaned, the detached sealing plate 5 makes it convenient for the staff to clean the fixing ring 14.

[0033] Further, such as Figure 3 As shown, a spring column 6 is fixedly connected to the top of the outer wall of the slider 12; and the connector body 1 is fixedly connected to the top of the outer wall of the spring column 6. The spring column 6 applies a certain pulling force to the slider 12, which helps the slider 12 to be more stable during operation. By setting the spring column 6, the burden of the third spring 24 and the second damper 25 is reduced when the device is working, thereby increasing the stability of the device.

[0034] Further, such as Figure 7 As shown, a plurality of balls 7 are arranged on the inner side wall of the reverse limit ring 18; the balls 7 rotate and contact the side wall of the reverse limit ring 18; the balls 7 contact the first support column 15; the balls 7 cannot be separated from the reverse limit column 18. When the device is working, the reverse limit ring 18 will slide and rub against the first support column 15, and the balls 7 will contact the first support column 15 instead of the reverse limit ring 18. The sliding friction between the reverse limit ring 18 and the first support column 15 is converted into rolling friction by the arranged balls 7, thereby increasing the smoothness of the device during operation.

[0035] Working principle: Press the connector body 1 downward, then the fixing ring 14 moves downward, the limit block 101 will contact the positive limit ring 17, when the connector body 1 moves to a certain position, the limit block 101 will be squeezed, and then the limit block 101 moves until the limit block 101 is located below the positive limit ring 17, and then when the connector body 1 is pulled upward, due to the restriction of the limit block 101 by the positive limit ring 17, the connector body 1 cannot be separated from the photovoltaic panel support frame 11, and when the fixing ring 14 is pressed downward so that the limit block 101 is located below the reverse limit ring 18, the limit block 101 pulls the reverse limit ring 18 to move until the reverse limit ring 18 contacts the positive limit ring 17, and continues to pull up, the connector body 1 can be separated from the photovoltaic panel support The support frame 11, through the set limit block 101, the positive limit ring 17 and the reverse limit ring 18, reduces the probability of the connector body 1 being detached from the device when the connector body 1 is pulled due to an accident during the operation of the device, increases the stability of the device, and at the same time reduces the time spent by the staff to fix the connector body 1, which is convenient for the staff to install the device. The fixing ring 14 is pressed to make the fixing ring 14 contact with the second support ring 23. At this time, the telescopic rod 21 and the second spring 22 are compressed by pressure, and the third spring 24 and the second damper 25 make the movement process of the slider 12 more stable. When the fixing ring 14 is released, the second spring 22 and the telescopic rod 21 will quickly return to the initial position, exert a certain upward force on the fixing ring 14, and assist the fixing ring 14 to be detached. The second spring 22 and the telescopic rod 21 are arranged so that when the staff needs to remove the connector body 1, they can continue to press the fixing ring 14 to make the fixing ring 14 pop out, reducing the difficulty of removing the fixing ring 14 for the staff, so that the staff can complete the disassembly of the connector body 1 in a short time, which is convenient for the staff to use the equipment. The fourth spring 32 pulls the connecting ring 31, and then applies a force to the reverse limiting ring 18 to approach the first support column 15. When the limiting block 101 does not contact the reverse limiting ring 18, the reverse limiting ring 18 maintains a state of being in contact with the first support column 15. After the limiting block 101 pushes the reverse limiting ring 18 to move upward, the fourth spring 32 pulls the reverse limiting ring 18 back to the initial position. By setting the connecting rope 3 and the fourth spring 32, when the device is installed in a non-vertical position, the phenomenon of the reverse limit ring 18 sliding due to gravity is reduced, so that it fits with the positive limit ring 17, and the situation that the limit block 101 is difficult to contact with the bottom of the positive limit ring 17 due to the movement of the position of the reverse limit ring 18 is reduced, and the failure rate of the device is reduced. When the device is working, the fixing ring 14 will be exerted with an upward elastic force, and the third damper 41 and the fifth spring 42 will absorb the excessive elastic force of the fixing ring 14. By setting the third damper 41 and the fifth spring 42, the impact force of the slider 12 on the connector body 1 when the fixing ring 14 is bounced is reduced, and the bending and breaking of the slider 12 due to the impact are reduced.Increase the stability of the equipment, push the sealing plate 5 to make up for the hollow position inside the fixing ring 14, and the sealing plate 5 can reduce the situation that the inside of the fixing ring 14 enters the dust and impurities when the equipment is in use, which affects the normal operation of the equipment. When the equipment is not used for a long time and the inner wall of the fixing ring 14 needs to be cleaned, the detached sealing plate 5 is convenient for the staff to clean the fixing ring 14. The spring column 6 applies a certain pulling force to the slider 12, which makes the auxiliary slider 12 more stable during operation. The spring column 6 is set to reduce the burden of the third spring 24 and the second damper 25 when the equipment is working, and increase the stability of the equipment. When the equipment is working, the reverse limit ring 18 will slide and rub with the first support column 15, and the ball 7 replaces the reverse limit ring 18 to contact the first support column 15 first. The set ball 7 makes the sliding friction between the reverse limit ring 18 and the first support column 15 become rolling friction, which increases the smoothness of the equipment during operation.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
