Example 1

Fig. 1 to 4 show an embodiment 1 of the present invention, and with reference to the illustrations in fig. 1 to 2, it can be seen that the seal mounting structure 1 of the intelligent street light pole for the internet of things includes:

a mounting base 11 defining a mounting cavity 112, the top of the mounting base 11 being open to form a mounting opening 111 communicating with the mounting cavity 112;

a grip 13 defining a grip cavity 139 having an abutment section 137 that is at least partially in abutment with the mounting cavity 112 through the mounting opening 111 and a clasping section 135 exposed at the mounting opening 111; and

a fitting member 12 surrounding at least a portion of the mounting base 11 and the fastening member 13 and defining a fitting cavity 124, including a pressing portion 121 surrounding at least a portion of the clasping section 135 and a fitting portion 125 detachably surrounding at least a portion of the mounting base 11;

the outer diameter of the clasping section 135 is a circular truncated cone shape which gradually decreases along the direction from top to bottom, and a squeezing surface 1211 matched with the outer periphery of the clasping section 135 is formed on the inner periphery of the squeezing portion 121; at least two upper and

lower relief grooves

133 and 134 are radially arranged in the circumferential direction of the holder 13; the upper relief groove 133 extends downward from the upper opening 131 of the fastening member 13 and penetrates through the inner and outer side walls of the fastening member 13, and the lower relief groove 134 extends upward from the lower opening 132 of the fastening member 13 and penetrates through the inner and outer side walls of the fastening member 13, so that when the outer circumference of the fastening member 13 is subjected to a radial pressing force, elastic deformation can occur, and the fastening member 13 contracts in the radial direction to switch from a released state to a clasped state; the mating member 12 can slide up and down relative to the mounting base 11 to switch between a locked state and an unlocked state, and the pressing surface 1211 continuously applies the radial pressing force to the outer periphery of the fastening member 13 when the mating member 12 slides down relative to the mounting base 11.

In practice, for the convenience of inserting the lamp pole into the clamping member, the diameter of the clamping cavity of the clamping member is slightly larger than the outer diameter of the lamp pole, so that an adjusting gap exists between the clamping cavity and the lamp pole during the assembling process, however, when the assembly is finished, the problems of unstable installation and poor sealing performance of the lamp post caused by the existence of the adjusting gap are also caused, in the scheme, the periphery of the clamping piece can generate elastic deformation after receiving radial compression force, so that the clamping piece contracts along the radial direction to switch from the loosening state to the clamping state, thereby make and to be in the lamp pole that can be convenient for when unclamping the state when holding tightly and insert the assembly, will hold tightly after the assembly and adjust to holding tightly the state and can eliminate the lamp pole and tightly hold the adjustment clearance between the chamber again, further improved waterproof sealing when having improved lamp pole installation stability, can satisfy the waterproof sealing demand of long-time outdoor installation.

Referring to fig. 2, the upper yielding slots 133 are configured to be composed of at least one yielding subset, each yielding subset includes a pair of upper yielding slots 133 adjacently disposed, a corresponding pair of upper yielding slots 133 in each yielding subset are disposed at an interval from each other to form a spacing space therebetween, and a corresponding spacing space in each yielding subset is aligned with a corresponding one of the lower yielding slots 134. Therefore, when the pressing surface 1211 continuously applies the radial pressing force to the periphery of the fastening piece 13, the sidewall of the clasping section 135 can rotate inwards around the root of the upper abdicating groove 133 to further realize that the clasping section 135 contracts inwards along the radial direction to clasp the lamp post, and meanwhile, the sidewall of the butting section 137 can rotate inwards around the root of the lower abdicating groove 134 to further realize that the butting section 137 contracts along the radial direction to further clasp the lamp post, and in addition, because the corresponding space of each abdicating subset is aligned with the corresponding lower abdicating groove 134, namely, the upper abdicating groove 133 is neither communicated with the lower abdicating groove 137 nor aligned with the lower abdicating groove 137, the fastening piece is prevented from being damaged due to the expansion and extension of the upper abdicating groove 133 and/or the lower abdicating groove 137 in the process of contracting along the radial direction, and the durability of the fastening piece is improved.

Discover in the practice, the fitting piece appears the pine easily long-term and installs the base and tightly hold a complex in-process and take off to lead to the unstable and broken sealed phenomenon of lamp pole installation to take place, for solving this problem, further improved the sealed mounting structure of wisdom street lamp pole for the thing networking:

referring to fig. 2 and 3, a locking ring 136 is formed on the outer circumference of the holder 13 and located between the abutting section 137 and the clasping section 135, and the locking ring 136 protrudes from the outer circumference of the holder 13 and extends outward; the inner periphery of the fitting 12 is formed with a locking portion 122 located between the pressing portion 121 and the fitting portion 125, and the locking portion 122 has a profile structure adapted to the locking ring 136.

As a further improvement, the outer circumference of the locking ring 136 is in an outer undulating configuration that is alternately undulating, including at least three circumferentially arranged outer valleys 1361; the outer valleys 1361 are arranged to be made up of at least one outer valley subset, each outer valley subset including a pair of adjacently disposed outer valleys 1361, a respective pair of outer valleys 1361 in each outer valley subset defining an outer peak 1362 therebetween; the outer peaks 1362 have a larger outer diameter than the outer valleys 1361.

As a further improvement, referring to fig. 3 and 4, each of the upper relief grooves 133 extends at least partially into the locking ring 136 and divides the locking ring 136 into at least two locking units at a respective one of the outer peaks 1362.

As a further improvement, the outer valleys 1361 smoothly transition with the adjacent outer peaks 1362.

As a further improvement, the inner periphery of the locking portion 122 is in an inner wave structure which alternately undulates, and the inner wave structure includes at least three circumferentially arranged inner valleys 1221; said valley 1221 is arranged to be made up of at least one inner valley subset, each inner valley subset including a pair of inner valleys 1221 arranged adjacently, a respective pair of inner valleys 1221 in each inner valley subset defining an inner peak 1222 located therebetween; the inner peak 1222 has a larger inner diameter than the inner valley 1221.

As a further improvement, referring to fig. 4 and 5, the inner valley 1221 and the adjacent inner peak 1222 are rounded.

Referring again to fig. 3 and 4, the locking portion 122 is rotatable relative to the locking ring 136 to switch the locking ring 136 between a released state and a clamped state; when the locking ring 136 is in the released state, each outer valley 1361 is aligned with a respective one of the inner valleys 1221 and each outer peak 1362 is aligned with a respective one of the inner peaks 1222; when the locking ring 136 is in the clamped condition, each outer valley 1361 is aligned with a respective one of the inner peaks 1222, and each outer peak 1362 is aligned with and interferes with a respective one of the inner valleys 1221. Therefore, when the locking ring 136 is in a clamped state, each outer peak 1362 is aligned with and abutted against a corresponding inner valley 1221, so that the locking ring 136 can further clamp the lamp post clamped in the clamping cavity when receiving radial pressing force, and the mounting stability and the waterproof sealing performance of the lamp post are further improved. In a preferred embodiment, the matching portion 125 is connected to the mounting base 11 by a screw thread to achieve a detachable connection, so that the matching element 12 can not only descend relative to the mounting base 11 during screwing in, but also continuously apply the radial pressing force to the outer circumference of the clasping section 135 of the clasping member 13 by the pressing surface 1211 during descending, so as to force the clasping member 13 to clasp the inserted lamp post radially, and after screwing in and matching to a certain extent, when the matching element 13 is continuously rotated to align and abut against each outer peak portion 1362 with a corresponding inner valley portion 1221, the lamp post can be further clasped and clamped, thereby further improving the mounting stability and the waterproof sealing performance.

In practice, it is further found that, although when the locking ring 136 is in the clamped state, each outer peak 1362 is aligned with and abutted against a corresponding inner valley 1221, so that the locking ring 136 can further clamp the lamp post clamped in the cavity when receiving a radial pressing force, due to the smooth fit between the locking ring 136 and the locking portion 122, the clamped state of the locking ring 136 cannot be stably maintained, and the locking ring 136 is easily disengaged from the clamped state by any circumferential disturbance, so that the lamp post cannot be further clamped, and in order to solve the problem, the sealing and mounting structure of the smart street lamp post for the internet of things is further improved: each of the upper relief grooves 133 extends into the lock ring 136 and penetrates the lock ring 136 at a corresponding one of the outer peak portions 1362 such that at least two catching grooves 1363 communicating with the upper relief grooves 133 are formed at the outer circumference of the lock ring 136; during the rotation of the locking portion 122, the trough 1221 is at least partially recessed into the retaining groove 1363 and its tendency to rotate is limited by the retaining groove 1363 and ends, so that the clamping state of the lock ring 136 can be maintained to some extent, and at this time, to switch the lock ring 136 from the clamping state to the release state, a slightly larger tangential force is applied to the locking portion 122 to make the trough 1221 pass over the tip of the corresponding retaining groove 1363.

the inner diameter of the mounting cavity 112 is the same as or slightly larger than the outer diameter of the lamp pole, the inner diameter of the mounting opening 111 is the same as or slightly larger than the outer diameter of the butt joint section 137 in the loosening state, so that a shoulder 1111 is formed between the bottom of the mounting opening 111 and the top of the mounting cavity 112, a sealing gasket 113 is embedded in the shoulder 1111, and a second sealing ring 114 is arranged among the sealing gasket 113, the bottom of the butt joint section 137 and the inner side wall of the mounting opening 111. The second sealing ring 114 is at least partially made of a soft and/or pliable material, which enables the second sealing ring 114 to seal between the sealing gasket 113, the bottom of the docking section 137 and the inner sidewall of the mounting opening 111. For example, the second seal ring 114 may be made of, but is not limited to, rubber and/or rubber-like materials, or may be of any configuration so long as the second seal ring 114 functions as described herein.

In the embodiment shown in fig. 2, the outer periphery of the sealing gasket 113 is formed with a lower sealing slope 1131 gradually expanding from top to bottom, the outer periphery of the bottom of the abutting section 137 is formed with an upper sealing slope 1371 gradually contracting from top to bottom, and the second sealing ring 114 is disposed between the upper sealing slope 1371, the lower sealing slope 1131 and the inner sidewall of the mounting opening 111.

In the embodiment shown in fig. 5, guide wheel 1223 is rotatably coupled to valley 1221 via a shaft 1223'.
