Therefore, improvements are needed. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention aims to provide a street lamp cover spraying and hanging device and its spraying process, which can enable the device to be adjusted and prevent the street lamp cover on the device from slipping off.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A street lamp cover spraying and suspension device includes a connecting rod, a fixing rod fixedly connected to the upper end of the connecting rod, a connecting sleeve contacting the outer side of the fixing rod, a hook fixedly connected to the upper end of the connecting sleeve, a connecting ring contacting the hook, an adjustment mechanism provided on the connecting sleeve, a support rod fixedly connected to the outer side of the connecting rod, an insert rod fixedly connected to the support rod, a support sleeve contacting the outer side of the insert rod, a street lamp cover provided on the outer side of the support sleeve, a fixing sleeve fixedly connected to the outer side of the insert rod, the fixing sleeve contacting the street lamp cover, and a limit mechanism provided on the street lamp cover.

[0006] In a preferred embodiment of the present invention, the adjusting mechanism includes a slide groove. The fixed rod has a slide groove inside, and a slider is slidably connected inside the slide groove. The slider is slidably connected to a connecting sleeve. A support ring is fixedly connected to the end of the slider away from the slide groove. A pull rod is fixedly connected to the side of the support ring away from the slider. A handle is fixedly connected to the end of the pull rod away from the support ring. A connecting seat is fixedly connected to the outside of the connecting sleeve. A pull rod is slidably connected inside the connecting seat. A first spring is provided on the outside of the pull rod. A guide groove is opened inside the connecting seat. A guide block is slidably connected inside the guide groove. A groove is opened inside the guide block. The guide block is fixedly connected to the support ring. The connecting seat is slidably connected to the slider. A threaded rod is threadedly connected inside the connecting seat, and a rotating block is fixedly connected to the threaded rod. The rotating block contacts the connecting seat. A first slot is formed inside the rotating block, and an elastic block is engaged inside the first slot. The elastic block is fixedly connected to the connecting seat. An annular sleeve is rotatably connected to the outside of the threaded rod, and a bolt is threadedly connected inside the annular sleeve. A semi-circular sleeve is slidably connected inside the connecting seat, and the semi-circular sleeve is fixedly connected to the annular sleeve. A semi-circular sealing sleeve is fixedly connected to the semi-circular sleeve, and the semi-circular sealing sleeve contacts the connecting seat. The semi-circular sealing sleeve also contacts the slider and the pull rod. By pulling the slider out of the groove, the connecting rod, the fixed rod, and the groove are moved downwards to the designated position. Then, the slider is moved into another groove, thereby limiting the connecting rod and adjusting the device for ease of use. Then, the threaded rod is rotated to create a threaded movement with the connecting seat. The movement of the threaded rod drives the movement of the semi-circular sealing sleeve. The semi-circular sealing sleeve moves and contacts the slider, while the other semi-circular sealing sleeve contacts the pull rod, thereby sealing the inside of the connecting seat and preventing the first spring inside the connecting seat from rusting.

[0007] As a preferred embodiment of the present invention, one end of the first spring is fixedly connected to the support ring, and the other end of the first spring is fixedly connected to the connecting seat. By designing the first spring, the support ring has an elastic force.

[0008] As a preferred embodiment of the present invention, a ball bearing is provided inside the groove, and the ball bearing contacts the connecting seat. By designing the ball bearing, the friction between the guide block and the connecting seat can be reduced.

[0009] As a preferred embodiment of the present invention, the threaded rod has a first annular groove inside, and a bolt is slidably connected inside the first annular groove. By designing the first annular groove, the bolt can slide within the first annular groove.

[0010] In a preferred embodiment of the present invention, the limiting mechanism includes a threaded hole. A threaded hole is formed inside the fixed sleeve, and a screw is threadedly connected to the inside of the threaded hole. A support block is fixedly connected to the streetlight cover, and the support block contacts the fixed sleeve. The screw is contacted inside the support block, and a connecting plate is fixedly connected to the end of the screw away from the threaded hole. The connecting plate contacts the support block. A second annular groove is formed inside the support block, and a movable sleeve contacts the inside of the second annular groove. The movable sleeve is fixedly connected to the connecting plate. A second slot is formed inside the movable sleeve, and a locking block is slidably connected inside the second slot. A wear-resistant block is fixedly connected inside the locking block, and a sliding groove is formed inside the wear-resistant block. A guide rod is slidably connected inside the sliding groove, and the guide rod is fixedly connected to the support block. A second spring is provided on the outside of the guide rod, and the locking block is slidably connected to the support block. The moving street light cover causes the support sleeve to move, and the support sleeve moves to contact the designated position on the plug. Then the screw is installed from the support block into the threaded hole, thereby limiting the street light cover and preventing the street light cover on the device from slipping off.

[0011] In a preferred embodiment of the present invention, a connecting block is fixedly connected to the end of the connecting plate away from the screw, and a rotating ring is fixedly connected to the side of the connecting block away from the connecting plate. By designing the rotating ring, the connecting block can be driven to rotate.

[0012] As a preferred embodiment of the present invention, one end of the second spring is fixedly connected to the locking block, and the other end of the second spring is fixedly connected to the support block. By designing the second spring, the locking block has an elastic force.

[0013] A spray coating process for a street lamp cover spray coating suspension device includes the following steps:

[0014] Step 1: Before using the device, move the handle away from the connecting seat. The handle moves the lever, which in turn moves the support ring. The support ring moves the slider and guide block, which in turn moves the groove. The groove moves the ball, and the support ring moves while compressing the first spring. The slider moves from the groove.

[0015] Step 2: Then move the connecting rod downwards. The downward movement of the connecting rod causes the fixed rod, support rod, and insertion rod to move downwards. The downward movement of the fixed rod causes the slide groove to move downwards. After the connecting rod, fixed rod, and slide groove have moved downwards to the designated position, release the handle. The elastic force of the first spring pushes the support ring to move. The movement of the support ring causes the slider to move. The slider moves into another slide groove, thereby limiting the connecting rod and adjusting the device to make it easier to use.

[0016] Step 3: Then rotate the rotating block. The rotation of the rotating block drives the first slot and the threaded rod to rotate. The rotation of the threaded rod causes threaded movement with the connecting seat, which in turn causes relative displacement of the threaded rod. The movement of the threaded rod causes the annular sleeve to move, which in turn causes the semi-circular sleeve to move, which in turn causes the semi-circular sealing sleeve to move. The semi-circular sealing sleeve moves and contacts the slider. The other semi-circular sealing sleeve contacts the pull rod, which causes the first slot to engage with the elastic block, thereby sealing the inside of the connecting seat and preventing the first spring inside the connecting seat from rusting.

[0017] Step 4: When the device is in use, the street lamp cover moves toward the insertion pole. The movement of the street lamp cover causes the support sleeve and support block to move. The support sleeve moves to the designated position on the insertion pole. Then, the rotating ring moves toward the support block. The movement of the rotating ring causes the connecting block to move. The movement of the connecting block causes the connecting plate to move. The movement of the connecting plate causes the moving sleeve and screw to move. The movement of the moving sleeve causes the second slot to move. The screw moves from the support block and inserts into the threaded hole.

[0018] Step 5: Then rotate the rotating ring. The rotation of the rotating ring drives the connecting block to rotate, which in turn drives the connecting plate to rotate. The rotating plate drives the moving sleeve and the screw to rotate, which in turn drives the second slot to rotate. The screw rotates and makes threaded movement with the threaded hole, which in turn causes the screw to have relative displacement. The rotation of the screw drives the moving sleeve to rotate and move at the same time. During the process of rotating and moving, the moving sleeve contacts the locking block, which in turn causes the locking block to move towards the second spring. The movement of the locking block drives the wear-resistant block to move, which in turn drives the sliding groove to move. The movement of the locking block compresses the second spring, and the screw rotates to the designated position in the threaded hole. The elastic force of the second spring then pushes the locking block to move. The movement of the locking block drives the wear-resistant block to move, which in turn drives the sliding groove to move. The locking block moves into the second slot, which limits the street light cover and prevents the street light cover on the device from slipping off.

[0019] Compared with the prior art, the advantages of this invention are:

[0020] (1) In this invention, by designing a slide groove, a slider, a support ring, a pull rod, a handle, and a connecting seat, the slider is pulled out of the slide groove, and the connecting rod, the fixing rod, and the slide groove are moved downward to a designated position. Then the slider is moved into another slide groove, thereby limiting the connecting rod and adjusting the device to make it easy to use. Then the threaded rod is rotated to generate a threaded movement with the connecting seat. The movement of the threaded rod drives the movement of the semi-circular sealing sleeve. The semi-circular sealing sleeve moves and contacts the slider. The other semi-circular sealing sleeve contacts the pull rod, thereby sealing the inside of the connecting seat and preventing the first spring inside the connecting seat from rusting.

[0021] (2) In this invention, by designing threaded holes, screws, support blocks, connecting plates, connecting blocks and rotating rings, the support sleeve is moved by moving the street lamp cover. The support sleeve moves to contact the designated position on the plug rod, and then the screw is installed from the support block into the threaded hole, thereby limiting the street lamp cover and preventing the street lamp cover on the device from slipping off.

[0038] In this embodiment, by pulling the slider 62 out of the groove 61, the connecting rod 1, the fixing rod 2 and the groove 61 are moved downward to a designated position. Then, the slider 62 is moved into another groove 61, thereby limiting the connecting rod 1 and adjusting the device to make it easier to use. Then, the threaded rod 612 is rotated to cause threaded movement with the connecting seat 66. The movement of the threaded rod 612 drives the movement of the semi-circular sealing sleeve 620. The semi-circular sealing sleeve 620 moves and contacts the slider 62. The other semi-circular sealing sleeve 620 contacts the pull rod 64, thereby sealing the inside of the connecting seat 66 and preventing the first spring 67 inside the connecting seat 66 from rusting.

[0050] In this embodiment, the second spring 1214 is designed so that the locking block 1210 has an elastic force.

[0051] A spray coating process for a street lamp cover spray coating suspension device includes the following steps:

[0052] Step 1: Before using the device, the pull block handle 65 is moved away from the connecting seat 66. The movement of the handle 65 causes the pull rod 64 to move, the movement of the pull rod 64 causes the support ring 63 to move, the movement of the support ring 63 causes the slider 62 and guide block 69 to move, the movement of the guide block 69 causes the groove 610 to move, the movement of the groove 610 causes the ball 611 to move, and the movement of the support ring 63 compresses the first spring 67, causing the slider 62 to move from the slide groove 61.

[0053] Step 2: Then move the connecting rod 1 downwards. The downward movement of the connecting rod 1 causes the fixed rod 2, the support rod 7, and the insertion rod 8 to move downwards. The downward movement of the fixed rod 2 causes the slide groove 61 to move downwards. After the connecting rod 1, the fixed rod 2, and the slide groove 61 move downwards to the designated position, release the handle 65. The elastic force of the first spring 67 pushes the support ring 63 to move. The movement of the support ring 63 causes the slider 62 to move. The slider 62 moves into another slide groove 61, thereby limiting the connecting rod 1 and adjusting the device to make it easier to use.

[0054] Step 3: Then rotate the rotating block 613. The rotation of the rotating block 613 drives the first slot 614 and the threaded rod 612 to rotate. The rotation of the threaded rod 612 causes threaded movement with the connecting seat 66, which in turn causes the threaded rod 612 to have relative displacement. The movement of the threaded rod 612 drives the annular sleeve 616 to move. The movement of the annular sleeve 616 drives the semi-circular sleeve 619 to move. The movement of the semi-circular sleeve 619 drives the semi-circular sealing sleeve 620 to move. The semi-circular sealing sleeve 620 moves and contacts the slider 62. The other semi-circular sealing sleeve 620 contacts the pull rod 64, which causes the first slot 614 to engage with the elastic block 615, thereby sealing the inside of the connecting seat 66 and preventing the first spring 67 inside the connecting seat 66 from rusting.

[0055] Step 4: When the device is in use, the street lamp cover 10 is moved toward the insertion rod 8. The movement of the street lamp cover 10 causes the support sleeve 9 and the support block 123 to move. The support sleeve 9 moves to the designated position on the insertion rod 8. Then, the rotating ring 126 is moved toward the support block 123. The movement of the rotating ring 126 causes the connecting block 125 to move. The movement of the connecting block 125 causes the connecting plate 124 to move. The movement of the connecting plate 124 causes the moving sleeve 128 and the screw 122 to move. The movement of the moving sleeve 128 causes the second slot 129 to move. The screw 122 moves from the support block 123 and inserts into the threaded hole 121.

[0056] Step 5: Then rotate the rotating ring 126. The rotation of the rotating ring 126 drives the connecting block 125 to rotate, which in turn drives the connecting plate 124 to rotate. The rotation of the connecting plate 124 drives the moving sleeve 128 and the screw 122 to rotate. The rotation of the moving sleeve 128 drives the second slot 129 to rotate. The rotation of the screw 122 causes threaded movement with the threaded hole 121, resulting in relative displacement of the screw 122. The rotation of the screw 122 drives the moving sleeve 128 to rotate and move simultaneously. During this rotation and movement, the moving sleeve 128 contacts the locking block 1210, causing the locking block 1210 to move towards the second spring 121. The movement of the four-directional locking block 1210 causes the wear-resistant block 1211 to move, which in turn causes the sliding groove 1212 to move. The movement of the locking block 1210 compresses the second spring 1214, causing the screw 122 to rotate to a designated position within the threaded hole 121. This causes the elastic force of the second spring 1214 to push the locking block 1210 to move, which in turn causes the wear-resistant block 1211 to move. The movement of the wear-resistant block 1211 in turn causes the sliding groove 1212 to move, and the locking block 1210 moves into the second locking groove 129. This limits the position of the street lamp cover 10, preventing it from slipping off the device.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.

9. The spraying process for a street lamp cover spraying suspension device according to any one of claims 1-8, characterized in that: The specific steps include: Step 1: Before using the device, the pull block handle (65) is moved away from the connecting seat (66). The movement of the handle (65) drives the pull rod (64) to move. The movement of the pull rod (64) drives the support ring (63) to move. The movement of the support ring (63) causes the slider (62) and guide block (69) to move. The movement of the guide block (69) causes the groove 610 to move. The movement of the groove (610) causes the ball (611) to move. At the same time, the movement of the support ring (63) compresses the first spring (67). The slider (62) moves from the slide groove (61). Step 2: Then move the connecting rod (1) downward. The downward movement of the connecting rod (1) drives the fixed rod (2), the support rod (7) and the insertion rod (8) to move downward. The downward movement of the fixed rod (2) drives the slide groove (61). After the connecting rod (1), the fixed rod (2) and the slide groove (61) move downward to the designated position, release the handle (65). The elastic force of the first spring (67) pushes the support ring (63) to move. The movement of the support ring (63) drives the slider (62) to move. The slider (62) moves into another slide groove (61), thereby limiting the connecting rod (1) and adjusting the device, making the device easy to use. Step 3: Then rotate the rotating block (613). The rotation of the rotating block (613) drives the first slot (614) and the threaded rod (612) to rotate. The rotation of the threaded rod (612) causes threaded movement with the connecting seat (66), which in turn causes the threaded rod (612) to generate relative displacement. The movement of the threaded rod (612) drives the annular sleeve (616) to move. The movement of the annular sleeve (616) drives the semi-circular sleeve 619 to move. The movement of the semi-circular sleeve (619) drives the semi-circular sealing sleeve (620) to move. The semi-circular sealing sleeve (620) moves and contacts the slider (62). The other semi-circular sealing sleeve (620) contacts the pull rod (64), which in turn causes the first slot (614) to engage with the elastic block (615), thereby sealing the inside of the connecting seat (66) and preventing the first spring (67) inside the connecting seat (66) from rusting. Step 4: When the device is in use, the lampshade (10) is moved toward the insertion rod (8). The movement of the lampshade (10) causes the support sleeve (9) and the support block (123) to move. The support sleeve (9) moves to the designated position on the insertion rod (8). Then, the rotating ring (126) is moved toward the support block (123). The movement of the rotating ring (126) causes the connecting block (125) to move. The movement of the connecting block (125) causes the connecting plate (124) to move. The movement of the connecting plate (124) causes the moving sleeve (128) and the screw (122) to move. The movement of the moving sleeve (128) causes the second slot (129) to move. The screw (122) moves from the support block (123) and inserts into the threaded hole (121). Step 5: Then rotate the rotating ring (126). The rotation of the rotating ring (126) drives the connecting block (125) to rotate. The rotation of the connecting block (125) drives the connecting plate (124) to rotate. The rotation of the connecting plate (124) drives the moving sleeve (128) and the screw (122) to rotate. The rotation of the moving sleeve (128) drives the second slot (129) to rotate. The rotation of the screw (122) causes threaded movement with the threaded hole (121), which in turn causes the screw (122) to have relative displacement. The rotation of the screw (122) drives the moving sleeve (128) to rotate and move at the same time. During the process of rotating and moving, the moving sleeve (128) contacts the locking block (1210), which in turn causes the locking block (1210) to move towards the second spring (121). 4) Directional movement: the movement of the locking block (1210) drives the movement of the wear-resistant block (1211), the movement of the wear-resistant block (1211) drives the movement of the sliding groove (1212), the movement of the locking block (1210) compresses the second spring (1214), the screw (122) rotates to the designated position in the threaded hole (121), and the elastic force of the second spring (1214) pushes the locking block (1210) to move. The movement of the locking block (1210) drives the movement of the wear-resistant block (1211), the movement of the wear-resistant block (1211) drives the movement of the sliding groove (1212), and the locking block (1210) moves into the second locking groove (129), thereby limiting the street lamp cover (10) and preventing the street lamp cover (10) on the device from slipping off.
