Description

Technical Field

[0001] This application relates to the field of street light base technology, specifically an adjustable height municipal street light stabilizing base device. Background Technology

[0002] Before installing municipal streetlights, the base needs to be pre-embedded. The base is usually composed of a rectangular plate and pre-embedded screws distributed at the four corners of the rectangular plate. The height of the rectangular plate is adjusted by rotating the nuts on the outside of the pre-embedded screws. After the concrete outside the base has solidified, the streetlight is installed on top of the base.

[0003] During the curing of the concrete outside the base, the pre-embedded bolts extending from the top of the rectangular plate need to be protected. The usual practice is to wrap the pre-embedded bolts with paper and then wrap the paper with tape. When installing the street light, the paper and tape need to be removed together. This method requires wrapping the pre-embedded bolts with paper and tape for each base installation. Since the paper cannot be reused during street light installation, it needs to be scrapped, resulting in a waste of resources.

[0004] Therefore, this application provides an adjustable height municipal street light stabilizing base device to solve the above problems. Utility Model Content

[0005] This application provides an adjustable height municipal street light stabilizing base device, aiming to solve the problems mentioned in the background art, which involve wrapping the pre-embedded screw with paper and then wrapping tape around the paper. When installing the street light, the paper and tape need to be torn off together. In this way, the pre-embedded screw needs to be wrapped with paper and tape every time the base is installed. Since the paper cannot be reused during the street light installation, it needs to be scrapped, resulting in waste of resources.

[0006] To achieve the above objectives, this application provides the following technical solution: an adjustable height municipal street light stabilizing base device, comprising a mounting plate, pre-embedded screws inserted at the four corners of the top of the mounting plate for mounting the street light, adjusting nuts sleeved on the outside of the pre-embedded screws for adjusting the height of the mounting plate, and fixing hoops fixedly disposed on the outer wall of the pre-embedded screws for fixing the position of the pre-embedded screws;

[0007] To ensure repeated protection of the embedded screw: a protective component is provided at the top of the mounting plate to protect the portion of the embedded screw extending out of the mounting plate, and a fixing bolt is inserted through the top of the mounting plate for fixing the protective component; the protective component includes a bottom protective tube and a top protective cover sleeved on the outside of the embedded screw to protect the embedded screw, and a fixing foot fixed on the outer wall of the bottom protective tube for fixing the fixing bolt. The street light base is installed by threading the adjusting nut onto the outside of the embedded screw, then inserting the embedded screw into the circular hole of the mounting plate. The base is then placed in the pit. The protective component is then fitted onto the portion of the embedded screw extending from the top of the mounting plate for protection. The embedded screw is then inserted into the bottom protective tube, and the fixing bolts are simultaneously inserted into the mounting holes of the fixing feet and the threaded grooves of the mounting plate to secure the bottom protective tube. Under the action of the fixing bolts and the fixing feet, the bottom protective tube and the mounting plate compress the sealing ring, thus preventing rainwater from corroding the embedded screw through the gap between the bottom protective tube and the mounting plate. For disassembly, the protective component can be separated from the mounting plate by removing the fixing bolts, and it can be reused, saving resources. When the length of the pre-embedded screw extending from the top of the mounting plate is greater than the length of the bottom protective tube, the top protective cover can be moved away from the bottom protective tube by pressing the insert block, thereby extending the length of the protective assembly to protect the pre-embedded screw. The bottom protective tube and the top protective cover reduce the overall size of the protective assembly, making it easier to store.

[0008] Preferably, to facilitate the installation of the pre-embedded screws and fixing bolts: the four corners of the top of the mounting plate are respectively provided with round holes for inserting the pre-embedded screws, and the top of the mounting plate is provided with threaded grooves for threaded connection of the fixing bolts. The pre-embedded screws are inserted through the round holes at the four corners of the mounting plate; the fixing bolts are fixedly installed to the mounting plate through the threaded grooves.

[0009] Preferably, to facilitate the protection of the embedded screw: the top protective cover is fitted over the outside of the bottom protective tube, one end of the fixing foot is fixedly connected to the outer wall of the bottom protective tube, and the top of the fixing foot, away from the bottom protective tube, has a mounting hole for inserting the fixing bolt. By inserting the fixing bolt into the mounting hole, the positions of the bottom protective tube and the top protective cover are fixed, thereby allowing the protective assembly to cover the embedded screw and achieve a protective effect.

[0010] Preferably, to seal the space between the mounting plate and the bottom protective tube: a sealing ring for sealing the space between the bottom protective tube and the mounting plate is fixedly connected to the bottom end of the bottom protective tube. The bottom protective tube is fixedly installed using the fixing bolts, thereby compressing and deforming the sealing ring between the bottom protective tube and the mounting plate, achieving a seal between the bottom protective tube and the mounting plate.

[0011] Preferably, to facilitate adjustment of the top protective cover's position: an adjusting rod for guiding the movement of the top protective cover is fixedly connected to the top end of the inner wall of the top protective cover, and a locking member for positioning the top protective cover is provided inside the adjusting rod. The adjusting rod guides the movement of the top protective cover, thereby allowing for adjustment of the top protective cover to different heights, and the locking member secures the top protective cover in place.

[0012] Preferably, to facilitate locking the position of the top protective cover: the top end of the bottom protective tube has a guide groove for inserting the adjusting rod, and the inner wall of the guide groove has a positioning hole for inserting the locking member. By inserting the insert into the positioning holes at different heights, the top protective cover can be adjusted to different heights, thereby satisfying the protection of the pre-embedded screws extending different lengths from the mounting plate.

[0013] Preferably, the adjusting rod has a cavity for installing the locking member inside, and the inner wall of the cavity has a through hole. The locking member includes a plug inserted into the through hole, a baffle fixedly connected to one end of the plug for restricting the movement of the plug, and an elastic block disposed on the side of the baffle away from the plug for pushing the baffle.

[0014] This application utilizes a protective component and fixing bolts design. The protective component is fitted over the portion of the pre-embedded screw that extends beyond the top of the mounting plate, providing protection. The pre-embedded screw is inserted into the bottom protective tube, and the fixing bolts are simultaneously inserted into the mounting holes of the fixing feet and the threaded grooves of the mounting plate to secure the bottom protective tube. The fixing bolts and fixing feet compress the sealing ring between the bottom protective tube and the mounting plate, preventing rainwater from seeping through the gap between them and eroding the pre-embedded screw. When the protective component is removed, the fixing bolts are easily removed, allowing the component to be separated from the mounting plate and reused, thus saving resources. If the length of the pre-embedded screw extending beyond the top of the mounting plate exceeds the length of the bottom protective tube, the top protective cover can be moved away from the bottom protective tube by pressing the insert block, extending the length of the protective component to better protect the pre-embedded screw. The combination of the bottom protective tube and the top protective cover reduces the overall size of the protective component, facilitating storage. Attached Figure Description

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] This embodiment provides an adjustable height municipal street light stabilizing base device, such as... Figure 1-7 As shown, the base device includes a mounting plate 1, pre-embedded screws 2 inserted at the four corners of the top of the mounting plate 1 for mounting streetlights, adjusting nuts 3 sleeved on the outside of the pre-embedded screws 2 for adjusting the height of the mounting plate 1, and fixing hoops 4 fixedly installed on the outer wall of the pre-embedded screws 2 for fixing the position of the pre-embedded screws 2.

[0026] To ensure repeated protection of the pre-embedded screw rod 2: a protective component 5 is installed at the top of the mounting plate 1 to protect the portion of the pre-embedded screw rod 2 extending out of the mounting plate 1, and a fixing bolt 6 is inserted through the top of the mounting plate 1 to secure the protective component 5. The protective component 5 includes a bottom protective tube 51 and a top protective cover 52 sleeved on the outside of the pre-embedded screw rod 2 for protection, and a fixing foot 53 fixed to the outer wall of the bottom protective tube 51 for fixing the bolt 6. The street light base is installed by threading the adjusting nut 3 onto the outside of the pre-embedded screw rod 2 and then inserting the pre-embedded screw rod 2 into the round hole of the mounting plate 1. The base is then placed in the pit. The protective component 5 is fitted over the portion of the embedded screw 2 extending from the top of the mounting plate 1 for protection. The embedded screw 2 is then inserted into the bottom protective tube 51, and the fixing bolts 6 are simultaneously inserted into the mounting holes of the fixing feet 53 and the threaded grooves of the mounting plate 1 to secure the bottom protective tube 51. Under the action of the fixing bolts 6 and the fixing feet 53, the bottom protective tube 51 and the mounting plate 1 compress the sealing ring 54, thus preventing rainwater from eroding the embedded screw 2 through the gap between the bottom protective tube 51 and the mounting plate 1. During disassembly, the protective component 5 can be separated from the mounting plate 1 by removing the fixing bolts 6, allowing for reuse and saving resources. When the length of the embedded screw 2 extending from the top of the mounting plate 1 is greater than the length of the bottom protective tube 51, the top protective cover 52 can be moved away from the bottom protective tube 51 by pressing the insert block 561, thereby extending the length of the protective component 5 to provide adequate protection for the embedded screw 2. By setting the bottom protective tube 51 and the top protective cover 52, the overall volume of the protective component 5 can be reduced, making it easier to store.

[0027] Furthermore, the mounting plate 1, the pre-embedded screw 2, the adjusting nut 3, and the fixing clamp 4 are existing technologies in the field of technology. The adjusting nut 3 is threaded onto the outer wall of the pre-embedded screw 2, and the four pre-embedded screws 2 are respectively inserted and set at the four corners of the mounting plate 1. The height of the mounting plate 1 is adjusted by rotating the adjusting nut 3. The outer walls of the four pre-embedded screws 2 are welded together with the fixing clamp 4 to form a whole, thereby preventing the pre-embedded screws 2 from shaking. The part of the pre-embedded screw 2 that extends out of the top of the mounting plate 1 is used to insert and connect with the street light base.

[0028] Specifically, to facilitate the installation of the pre-embedded screw 2 and the fixing bolt 6: Four round holes for inserting the pre-embedded screw 2 are respectively opened at the four corners of the top of the mounting plate 1, and threaded grooves for threaded connection of the fixing bolt 6 are opened at the top of the mounting plate 1. The pre-embedded screw 2 is inserted through the round holes at the four corners of the mounting plate 1; the fixing bolt 6 is fixedly installed to the mounting plate 1 through the threaded grooves. The size of the round holes matches the size of the pre-embedded screw 2, the inner thread of the threaded groove meshes with the outer thread of the fixing bolt 6, the round holes penetrate the mounting plate 1, and the threaded grooves are circular grooves that do not penetrate the mounting plate 1. At least two threaded grooves are provided around each round hole, and the two threaded grooves are distributed at right angles to the round hole, with the round hole located at the intersection of the right angles.

[0029] Specifically, to facilitate the protection of the embedded screw 2: the top protective cover 52 is fitted over the bottom protective tube 51, one end of the fixing foot 53 is fixedly connected to the outer wall of the bottom protective tube 51, and the top of the fixing foot 53, away from the bottom protective tube 51, has a mounting hole for inserting the fixing bolt 6. By inserting the fixing bolt 6 into the mounting hole, the positions of the bottom protective tube 51 and the top protective cover 52 are fixed, thereby allowing the protective assembly 5 to cover the embedded screw 2 and achieve a protective effect. The top protective cover 52 is larger than the bottom protective tube 51, so that the top protective cover 52 fits over the bottom protective tube 51.

[0030] More specifically, to seal the space between the mounting plate 1 and the bottom protective tube 51: a sealing ring 54 is fixedly connected to the bottom end of the bottom protective tube 51 for sealing the space between the bottom protective tube 51 and the mounting plate 1. The bottom protective tube 51 is fixedly installed using fixing bolts 6, thereby compressing and deforming the sealing ring 54 between the bottom protective tube 51 and the mounting plate 1, achieving a seal between the bottom protective tube 51 and the mounting plate 1. The sealing ring 54 is bonded and fixed to the bottom protective tube 51. The sealing ring 54 is a rubber ring. By compressing and deforming the sealing ring 54, a seal is achieved between the bottom protective tube 51 and the mounting plate 1, thereby preventing rainwater from corroding the threads of the embedded screw 2 through the gap between the mounting plate 1 and the bottom protective tube 51.

[0031] Specifically, to facilitate adjustment of the position of the top protective cover 52: an adjusting rod 55 for guiding the movement of the top protective cover 52 is fixedly connected to the top of the inner wall of the top protective cover 52, and a locking member 56 for positioning the top protective cover 52 is provided inside the adjusting rod 55. The adjusting rod 55 can guide the movement of the top protective cover 52, thereby adjusting the height of the top protective cover 52. Under the action of the locking member 56, the top protective cover 52 is fixed.

[0032] More specifically, to facilitate locking the position of the top protective cover 52: the top end of the bottom protective tube 51 has a guide groove for inserting the adjusting rod 55, and the inner wall of the guide groove has a positioning hole for inserting the locking member 56. The adjusting rod 55 has a cavity for installing the locking member 56, and the inner wall of the cavity has a through hole. The locking member 56 includes an insert block 561 inserted into the through hole, a baffle 562 fixedly connected to one end of the insert block 561 to restrict its movement, and an elastic block 563 located on the side of the baffle 562 away from the insert block 561 to push the baffle 562. By inserting the insert block 561 into positioning holes of different heights, the top protective cover 52 can be adjusted to different heights, thereby satisfying the protection of the pre-embedded screws 2 extending from the mounting plate 1 at different lengths. Two guide grooves are symmetrically provided, and the size of the guide grooves is adapted to the size of the adjusting rod 55. The positioning holes are provided on the side of the guide groove away from the pre-embedded screw 2. Multiple positioning holes are provided vertically at equal intervals. The positioning holes and through holes are the same size and are adapted to the insert block 561. The contact part of the insert block 561 with the baffle 562 is welded and fixed. The size of the baffle 562 is 1.2 times the size of the through hole. Both the baffle 562 and the elastic block 563 are set in the cavity. The elastic block 563 is an elastic rubber block. The elastic block 563 is always in a compressed state in the cavity, thereby pushing the baffle 562 and causing the insert block 561 to be stably inserted into the positioning hole, thereby restricting the vertical movement of the adjusting rod 55 and realizing the positioning for adjusting the height of the top protective cover 52. The adjusting rod 55 is welded and fixed to the top of the inner wall of the top protective cover 52. The length of the adjusting rod 55 is longer than the length of the top protective cover 52, but the insert block 561 is inserted into the positioning hole at the highest position. The top protective cover 52 is fitted over the bottom protective tube 51, and the bottom protective tube 51 and the top protective cover 52 will not separate vertically. The locking member 56 is located at the end of the adjusting rod 55 away from the top protective cover 52. By adjusting the height of the top protective cover 52, different lengths of the pre-embedded screw 2 extending from the top of the mounting plate 1 are covered to protect its external threads.
