Wherein, two adjacent photovoltaic modules adopt well briquetting to fix on the support purlin, well briquetting passes through bolted connection with the purlin to with photovoltaic module chucking. The middle pressure block bolt of the fixed photovoltaic module can be loosened due to vibration and other reasons in the flat time, so that the bolt is fastened to avoid falling of the module.

In view of the above, the present utility model provides a fastening device for a press block bolt in a photovoltaic module, which includes a rotating member, an elastic member, a first supporting member and a second supporting member. The elastic piece is sleeved and connected with the two supporting pieces, the two supporting pieces are in sliding connection, so that the middle pressing block bolt is contained in a space formed between the two supporting pieces, and the head part and the tail part of the middle pressing block bolt are ensured to be clamped by the two supporting pieces. The nut is further rotated relative to the middle pressing block bolt through the rotating piece to clamp the photovoltaic module. The fastening tool is used for conveniently fastening the bolt, so that the bolt is prevented from rotating along with the connecting shaft of the nut in the fastening process, and the working efficiency is improved.

See fig. 1, 2 and 3. The utility model provides a fastening device for a pressing block bolt in a photovoltaic module, which comprises a fixed module 10 and a rotating piece 20, wherein the fixed module 10 comprises an elastic piece 110, a first supporting piece 120 and a second supporting piece 130, the first supporting piece 120 comprises a first supporting part 121 and a second supporting part 122 which are opposite, and the second supporting piece 130 comprises a third supporting part 131 and a fourth supporting part 132 which are opposite; the extending directions of the first support portion 121 and the third support portion 131 coincide, the first support portion 121 has a first end portion 1211, the third support portion 131 has a second end portion 1311 opposite to the first end portion 1211, and a space 140 is provided between the first end portion 1211 and the second end portion 1311.

The second supporting part 122 is slidably connected with the fourth supporting part 132, the elastic member 110 is sleeved on the second supporting part 122 and the fourth supporting part 132, the second supporting part 122 and the fourth supporting part 132 are both connected with the elastic member 110, and one of the second supporting part 122 and the fourth supporting part 132 slides relative to the other, so that the middle-pressure block bolt is accommodated in the space 140; one of the first end 1211 and the second end 1311 is used for being clamped with the head of the middle pressing block bolt, the other is abutted with the tail of the middle pressing block bolt, the rotating piece 20 is arranged on the other, and the rotating piece 20 rotates relative to the other and the middle pressing block bolt so as to drive the upper nut of the middle pressing block bolt to rotate relative to the middle pressing block bolt, so that the fastened photovoltaic module is fastened.

In particular, the securing assembly 10 is configured to maintain the middling pressure block bolt in a clamped condition during tightening. The fixing assembly 10 includes an elastic member 110, a first supporting member 120 and a second supporting member 130, wherein the first supporting member 120 and the second supporting member 130 are disposed relatively up and down along the Z-axis direction, and the first supporting member 120 includes two opposite supporting portions, namely a first supporting portion 121 on the right side and a second supporting portion 122 on the left side; the second support 130 also includes two opposite support portions, namely a third support portion 131 on the right side and a fourth support portion 132 on the left side. The first support portion 121 and the third support portion 131 each have a certain length in the Z-axis direction, and are located on the same horizontal line, that is, the extending directions of the first support portion 121 and the third support portion 131 coincide. A space 140 is formed between the first end 1211 of the first support part 121 and the second end 1311 of the third support part 131 to provide a receiving space for the bolt.

The elastic member 110 is sleeved on the second supporting portion 122 and the fourth supporting portion 132, and the second supporting portion 122 and the fourth supporting portion 132 are slidably connected. By applying a tensile force to the first support 120 in the Z-axis direction, at this time, the elastic member 110 is elastically deformed and the second support 122 slides upward relative to the fourth support 132, so that the space 140 between the first end 1211 and the second end 1311 is increased, so that the middle-pressure block bolts with different lengths can be accommodated in the space 140. It will be appreciated that by applying a downward pulling force to the second support 130 along the Z-axis direction, the elastic member 110 is elastically deformed and the fourth support 132 slides downward relative to the second support 122, so that the space 140 between the first end 1211 and the second end 1311 can be increased, so that the middle-pressure block bolts with different lengths can be accommodated in the space 140.

After the middle press block bolts are received within the space 140, one of the first end 1211 and the second end 1311 is configured to engage a head portion of the middle press block bolt and the other is configured to engage a tail portion of the middle press block bolt. So ensure that the middle pressing block bolt is clamped by the fastening tool and can not shake. The rotating piece 20 is arranged on the other one, and the rotating piece 20 rotates relative to the other one and the middle pressing block bolt so as to drive the nut on the middle pressing block bolt to rotate. It is understood that during the nut rotation process, the bolt will not rotate with the nut shaft, and the two are in threaded engagement to fasten the photovoltaic module.

For example, in actual use, a fastening tool is placed in the gap between two adjacent photovoltaic modules to fasten the center press block bolts. First, the first end 1211 is engaged with the head of the middle block bolt, and after the engagement is completed, a tensile force is applied to the fourth support 132, so that the elastic member 110 is elastically deformed and the fourth support 132 slides with respect to the second support 122. Next, when the spacing 140 between the first end 1211 and the second end 1311 matches the length of the bolt to be fastened, the tension is released to bring the second end 1311 into abutment with the tail of the middling pressure block bolt. Finally, the rotating member 20 disposed on the second end 1311 rotates relative to the second end 1311 and the middle pressing block bolt, and drives the nut on the middle pressing block bolt to rotate relative to the middle pressing block bolt, so that the nut is in threaded connection with the middle pressing block bolt to fasten the photovoltaic module.

In some possible embodiments, in actual use, first, the second end 1311 is clamped with the head of the middle-pressure block bolt, and after the clamping is completed, a pulling force is applied to the second supporting portion 122, so that the elastic member 110 is elastically deformed and the second supporting portion 122 slides relative to the fourth supporting portion 132. Next, when the spacing 140 between the first end 1211 and the second end 1311 matches the length of the bolt to be fastened, the tension is released to bring the first end 1211 into abutment with the tail of the middling pressure block bolt. It will be appreciated that in particular implementations, the rotor 20 is disposed on the first end 1211. Finally, the rotating member 20 is rotated relative to the first end 1211 and the middle press block bolt, and drives the nut on the middle press block bolt to rotate relative to the middle press block bolt, so that the nut is in threaded connection with the middle press block bolt to fasten the photovoltaic module.

In a specific implementation, when one of the first end portion 1211 and the second end portion 1311 is clamped with the head of the middle-pressure block bolt and the other is abutted with the tail of the middle-pressure block bolt, the clearance between two adjacent photovoltaic modules is small, so that the moving range of the fastening tool is affected, and therefore, the situation that the one of the first end portion 1211 and the second end portion 1311 is not clamped with the head of the middle-pressure block bolt is caused, the bolt can rotate along with the nut connecting shaft in the fastening process, after the relative angle between the bolt and the fastening device is changed, one of the first end portion 1211 and the second end portion 1311 can be clamped with the head of the middle-pressure block bolt under the action of elastic deformation of the elastic piece 110, the bolt is clamped tightly and cannot rotate along with the nut connecting shaft, and the fastening work can be completed by continuing to rotate the rotating piece 20.

According to the fastening device for the middle press block bolt of the photovoltaic module, the elastic piece 110 is sleeved on the two supporting pieces and is connected with the two supporting pieces in a sliding mode, so that the middle press block bolt is contained in the space 140 formed between the two supporting pieces, and the head part and the tail part of the middle press block bolt are ensured to be clamped by the two supporting pieces. The nut is further rotated relative to the middling pressure block bolt by the rotator 20 to clamp the photovoltaic module. The fastening tool is used for conveniently fastening the bolt, so that the bolt is prevented from rotating along with the connecting shaft of the nut in the fastening process, the working efficiency is improved, and the effect that the bolt can be fastened reliably by single operator is achieved.

In some embodiments, rotor 20 has a socket 210 thereon, socket 210 is sleeved over the other of first end 1211 and second end 1311, and socket 210 is configured to receive the tail.

Specifically, when the rotating member 20 is disposed on the second end 1311, the socket portion 210 of the rotating member 20 is sleeved on the second end 1311, and the socket portion 210 accommodates the tail portion, so that the tail portion of the middle press block bolt can abut against the second end 1311. When the rotary member 20 is disposed on the first end 1211, the socket portion 210 of the rotary member 20 is sleeved on the first end 1211, and the socket portion 210 accommodates the tail portion so that the tail portion of the middle press block bolt can abut against the first end 1211.

By way of example, reference is continued to fig. 2 and 3. In actual use, first, the first end 1211 is engaged with the head of the middle block bolt, and after the engagement is completed, a tensile force is applied to the fourth support 132, so that the elastic member 110 is elastically deformed and the fourth support 132 slides with respect to the second support 122. Next, when the spacing 140 between the first end 1211 and the second end 1311 matches the length of the bolt to be fastened, the tension is released to allow the tail of the middle press block bolt to be received in the socket 210 and abut the second end 1311. Finally, the socket 210 is rotated relative to the second end 1311 and the middle press block bolt, and drives the nut on the middle press block bolt to rotate relative to the middle press block bolt, so that the nut is in threaded connection with the middle press block bolt to fasten the photovoltaic module.

It can be appreciated that, when the rotating member 20 is disposed on the first end 1211, in a specific implementation, the second end 1311 is first engaged with the head of the middle pressing bolt, and after the engagement is completed, a pulling force is applied to the second supporting portion 122, so that the elastic member 110 is elastically deformed and the second supporting portion 122 slides relative to the fourth supporting portion 132. Next, when the spacing 140 between the first end 1211 and the second end 1311 matches the length of the bolt to be fastened, the tension is released to allow the tail of the middle press block bolt to be received in the socket 210 and abut against the first end 1211. Finally, the socket 210 is rotated relative to the first end 1211 and the middle press block bolt, and drives the nut on the middle press block bolt to rotate relative to the middle press block bolt, so that the nut is in threaded connection with the middle press block bolt to fasten the photovoltaic module.

In some examples, the rotating member 20 is a ratchet wrench.

Specifically, the ratchet wrench includes a socket portion 210 and an operating lever 220, and by rotating the operating lever 220, the socket portion 210 is rotated with respect to the second end 1311 and the middle press block bolt, or the socket portion 210 is rotated with respect to the first end 1211 and the middle press block bolt, and when the socket portion 210 contacts the nut on the middle press block bolt, the ratchet wrench can be tightened and loosened by changing the position of the socket portion 210. The socket part 210 is internally provided with a ratchet mechanism, the operating handle 220 is rotated along one direction, and after the socket part 210 is sleeved on the nut, the ratchet is snapped on the nut in the socket part 210 to drive the nut on the middle-pressure block bolt to rotate relative to the middle-pressure block bolt. After the tightening is completed, the operating handle 220 is rotated in the other direction, and the ratchet releases the nut to effect the loosening.

The nut on the middle pressure block bolt is a small hexagonal cylinder, and the socket joint part 210 of the ratchet wrench is a hexagonal socket matched with the small hexagonal cylinder, so that the socket joint part 210 can be guaranteed to better fix the nut on the middle pressure block bolt, and larger torque is transmitted when the middle pressure block bolt is screwed or unscrewed, so that a better fastening effect is achieved.

In some examples, the rotating member 20 is a torque wrench.

Specifically, the size of the tightening torque can be controlled by using a torque wrench so as to ensure that the middle press block bolt achieves the expected tightening force. The torque wrench includes a socket 210 and an operating lever 220, and includes an adjustor to conveniently set a desired torque value, unlike a ratchet wrench. In use, by rotating the operating lever 220 of the torque wrench, the socket portion 210 is rotated relative to the second end 1311 and the middle press block bolt, or the socket portion 210 is rotated relative to the first end 1211 and the middle press block bolt, and when the socket portion 210 is socket-jointed to the nut on the middle press block bolt, the torque wrench is continuously rotated to drive the nut on the middle press block bolt to rotate relative to the middle press block bolt. When the torque wrench rotates to set torque, a reverse torque is generated, which indicates that the photovoltaic module is clamped, and the required fastening force is ensured.

It can be appreciated that, the socket portion 210 of the torque wrench is matched with the nut on the press block bolt in size and shape, so that the socket portion 210 can better fix the nut on the middle press block bolt, and transmit larger torque when tightening or loosening, thereby realizing better fastening effect.

In some embodiments, one of the first end 1211 and the second end 1311 has a clip portion 150 thereon, the clip portion 150 is configured to be inserted into a groove of the head, and the clip portion 150 mates with the groove.

Specifically, when the first end 1211 is clamped to the head of the middle pressing block bolt, the clamping portion 150 of the first end 1211 is inserted into the groove of the head of the middle pressing block bolt, and meanwhile, the clamping portion 150 is matched with the groove to ensure that the first supporting member 120 clamps the middle pressing block bolt, so as to limit the head of the middle pressing block bolt from being deflected. It can be appreciated that when the second end 1311 is clamped with the head of the middle pressing block bolt, the clamping portion 150 of the second end 1311 is inserted into the groove of the head of the middle pressing block bolt, and meanwhile, the clamping portion 150 is matched with the groove to ensure that the second supporting member 130 clamps the middle pressing block bolt, so as to limit the head of the middle pressing block bolt from being deflected. Therefore, the middle pressure block bolt is further ensured not to rotate along with the nut connecting shaft in the fastening process, and the fastening working efficiency is improved.

Illustratively, the bolt head of the medium-pressure block is a round head, and the groove on the bolt head is an inner hexagon. By configuring the clamping portion 150 to be hexagonal in shape and to match the dimensions of the recess so as to plug into the internal hexagonal recess, one of the first end 1211 and the second end 1311 is clamped to the head of the middle compression block bolt.

In some embodiments, the first support 120 further includes a first connection portion 123, and the first support portion 121 and the second support portion 122 are disposed on the same side of the first connection portion 123.

Specifically, the first connection portion 123 has a certain length in the X-axis direction, and the first support portion 121 and the second support portion 122 are connected at both ends of the first connection portion 123 and are located at the lower side of the first connection portion 123. The first support 120 is thus generally U-shaped with a downward opening.

By providing the first connection portion 123, in actual use, after the second end portion 1311 is engaged with the head portion of the middle-pressure block bolt, by holding the first connection portion 123 by hand and applying a tensile force, when the elastic member 110 is elastically deformed and the second support portion 122 slides relative to the fourth support portion 132, the space 140 between the first end portion 1211 and the second end portion 1311 is correspondingly enlarged to match the size of the middle-pressure block bolt. Thus, the operation is convenient, and the labor is saved.

In some embodiments, the second support 130 further includes a second connection portion 133, and the third support portion 131 and the fourth support portion 132 are disposed on the same side of the second connection portion 133.

Specifically, the second connection portion 133 has a certain length in the X-axis direction, and the third and fourth support portions 131 and 132 are connected at both ends of the second connection portion 133 and are located at the upper side of the first connection portion 123. The second support 130 is thus generally U-shaped with an upward opening.

By providing the second connection portion 133, in actual use, after the first end portion 1211 is engaged with the head portion of the middle-pressure block bolt, by holding the second connection portion 133 by hand and applying a tensile force, when the elastic member 110 is elastically deformed and the fourth support portion 132 slides relative to the second support portion 122, the space 140 between the first end portion 1211 and the second end portion 1311 is correspondingly enlarged to match the size of the middle-pressure block bolt. Thus, the operation is convenient, and the labor is saved.

In some embodiments, one of the second support portion 122 and the fourth support portion 132 is inserted into the other.

Specifically, when the second supporting portion 122 is inserted into the fourth supporting portion 132, or the fourth supporting portion 132 is inserted into the second supporting portion 122, the second supporting portion 122 is slidably connected with the fourth supporting portion 132, so that the second supporting portion 122 and the fourth supporting portion 132 slide relatively, and are always on the same horizontal line in the Z-axis direction, so that stability of the relative sliding is improved.

For example, refer to fig. 4 and 5. The second supporting portion 122 is a hollow rod, the fourth supporting portion 132 is a solid rod, and the radial dimension of the hollow rod is larger than that of the solid rod, so that the solid rod can be inserted into the hollow rod and can slide relatively. It will be appreciated that when the second support 122 is a solid rod, the fourth support 132 is correspondingly configured as a hollow rod.

In a specific example, the elastic member 110 is a spring 111.

Specifically, the spring 111 is a mechanical part that works by using elasticity, and the spring 111 deforms under the action of an external force, and returns to its original state after the external force is removed. In actual use, after the tension is applied to the first support 120 or the second support 130, the second support 122 and the fourth support 132 slide relatively and the spring 111 is in a stretched state, so that the distance 140 between the first end 1211 and the second end 1311 is ensured to be increased to accommodate the middle-pressure block bolt, and when the external force is removed, the spring 111 performs a resetting action, and the distance 140 is correspondingly changed and adapted to the length of the middle-pressure block bolt, so that one of the first end 1211 and the second end 1311 is used for being clamped with the head of the middle-pressure block bolt, and the other is abutted with the tail of the middle-pressure block bolt.

In some examples, an outer wall of the second support 122 is fixedly connected to one end of the spring 111, and the other end of the spring 111 is fixedly connected to an outer wall of the fourth support 132.

Specifically, the spring 111 is sleeved on the outer walls of the second supporting portion 122 and the fourth supporting portion 132, the spring 111 has opposite ends in the Z-axis direction, the upper end of the spring 111 is fixedly connected with the outer wall of the second supporting portion 122, and the lower end of the spring 111 is fixedly connected with the outer wall of the fourth supporting portion 132, so that after a tensile force is applied to the first supporting member 120 or the second supporting member 130, the spring 111 stretches and drives the second supporting portion 122 and the fourth supporting portion 132 to slide relatively, and after the tensile force is released, the spring 111 resumes to drive the second supporting portion 122 and the fourth supporting portion 132 to return to the initial relative positions.
