Technical Field
[0001] This invention belongs to the field of street light technology, specifically relating to a snap-on quick-release modular street light that is easy to maintain. Background Technology
[0002] Modular streetlights design each part of the streetlight, such as the lamp head, lamp pole, and power supply, into independent modules. This design improves the convenience of maintenance and replacement to a certain extent. When a module fails, maintenance personnel only need to locate the faulty module and disassemble it separately for maintenance or replacement, without having to disassemble the entire streetlight on a large scale, thus lowering the maintenance threshold.
[0003] Currently, modular streetlights are suitable for multiple scenarios. However, when used in scenic areas, mountaintops, or coastal roads where heavy fog is common and the air contains high levels of water molecules, the lamp head, as a key component, has electronic components such as the lamp board that are sensitive to moisture. Sufficient sealing is required to prevent water molecules from entering the lamp head and to avoid short circuits caused by moisture.
[0004] Existing lamp holder sealing structures mostly use simple sealing strips or gaskets for sealing. Elastic elements (sealing strips or gaskets) are placed on the contact surface between the lamp body top or side and the lamp cover, using their elastic deformation to fill gaps and achieve a certain sealing effect. This sealing method can prevent moisture and dust from entering to some extent, but it is difficult to disassemble and reassemble conveniently during maintenance. Therefore, a balance must be struck between easy disassembly and maintenance and sealing performance. For example, if the elastic element is placed on the top of the lamp body, during installation after maintenance, the entire lamp cover must be evenly pressed against the elastic element to ensure that the entire lamp cover is pressed downwards simultaneously, thus ensuring consistent pressure on the elastic element and a consistent seal between the lamp cover and the lamp body. Uneven force will inevitably cause the element to lift, making it difficult to latch the lamp cover onto the lamp body and hindering disassembly and reassembly. If the elastic element is placed on the side of the lamp body, during lamp cover disassembly and reassembly, if the lamp cover moves up or down, the friction between the side of the lamp cover and the elastic element will cause excessive compression, resulting in severe deformation and damage to the elastic element, affecting subsequent sealing performance.
[0005] Therefore, a snap-on quick-release modular street light is proposed, which can maintain sufficient sealing to prevent water molecules from entering the lamp head, and can also be easily disassembled and assembled during maintenance. Summary of the Invention
[0006] To address the aforementioned problems in the existing technology, this invention provides a snap-on quick-release modular street light that is easy to maintain.
[0007] The objective of this invention can be achieved through the following technical solutions:
[0008] A modular street light with easy-to-maintain snap-on design, characterized in that it includes a lamp body, a lamp cover, and a retractable seal. The retractable seal is located at the joint between the lamp body and the lamp cover. The retractable seal includes a rubber ring and a ring spring. The ring spring is located inside the rubber ring. The ring spring, through its own extension and retraction, causes the rubber ring to tighten around the lamp body, thus achieving a seal. The lamp cover also includes a snap-on component and a locking strip. The locking strip is located on the outside of the lamp cover. The snap-on component is located at one end of the joint, and the other end is engaged with the locking strip. By engaging the snap-on component with the locking strip, the retractable seal can be released from its sealing state.
[0009] Preferably, a sealing groove is provided at the joint between the lamp cover and the lamp body, the rubber ring is placed in the sealing groove, the rubber ring is annular and hollow, and the annular spring is provided inside the rubber ring.
[0010] Preferably, the annular spring is formed by spirally winding spring wire into a ring shape.
[0011] Preferably, the rubber sleeve is annular and hollow, and has several rubber strips on one side.
[0012] Preferably, the fastener includes a limiting rod, a fastening plate, and an aluminum strip. A fixing rod is fixed on the semi-circular groove on the upper surface of the sealing groove. One end of the aluminum strip is fixedly set to the fixing rod as the head end. A notch is opened on the lamp cover, and the other end passes through the notch and is fixed to the fastening plate. A slot is opened at the lower part of the fastening plate to engage with the fastening strip.
[0013] Preferably, the aluminum strip is made of a flexible material.
[0014] Preferably, the buckle further includes a limiting rod, and the aluminum strip has a hollow cavity in the middle, with the limiting rod located inside the hollow cavity.
[0015] Preferably, the lamp body is provided with a snap-fit part on both sides at one end. The snap-fit part has an outwardly protruding arc surface at the top and a slot at the bottom. The lamp cover is fixedly installed with the snap-fit plate at the upper part of the snap-fit part. The snap-fit plate is made of elastic material with an inwardly curved structure at the bottom, and has the ability to deform.
[0016] Preferably, one end of the lamp body is provided with a limiting pin, and the lamp cover has a vertical slide rail. The lamp cover is slidably connected to the lamp body through the vertical slide rail. The vertical slide rail is made of a deformable material and can be pried open to disengage the vertical slide rail from the limiting pin.
[0017] The beneficial effects of this invention are as follows:
[0018] 1. When the fasteners and the strip engage, several sets of fasteners squeeze the retractable seal away from the arc groove, so that the retractable seal is completely located in the sealing groove, thus releasing the seal. When the fasteners and the strip disengage, the retractable seal retracts and re-fits the arc groove through its own tensile force to achieve a seal. Through the tensile engagement of the fasteners and the tensile characteristics of the retractable seal, the seal can be easily released during maintenance and disassembly, and automatically and quickly reset during installation, while also preventing damage and detachment of the sealing ring or sealing strip.
[0019] 2. The ring spring is opened at multiple points by multiple sets of fasteners, so that the rubber sleeve is separated from the arc groove and the sealing state is released. When the multiple sets of fasteners are released, the ring spring drives the rubber sleeve to retract synchronously through its own elasticity and re-fit tightly with the arc groove to achieve a seal. At the same time, the rigid ring formed by its own spiral can prevent excessive deformation of the rubber sleeve and improve the fastening stability of the rubber sleeve to the lamp cover and lamp body.

[0030] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.
[0031] Please see Figures 1-8 This embodiment provides a snap-on quick-release modular street light that is easy to maintain, including a lamp body 1, a lamp cover 2, and a retractable sealing component. The lamp body 1 and lamp cover 2 are the lamp heads in the modular street light, serving an illumination function. The lower concave contour of the lamp cover 2 is larger than the contour of the lamp body 1, allowing the lamp cover 2 to snap onto the lamp body 1 to form an inner cavity space (e.g., ...). Figure 2 As shown), the lamp body 1 is located in the inner cavity space and has a lamp board and lamp beads. To ensure sealing, the lamp beads are tightly fitted to the lamp body 1. The lamp cover 2 is flipped on the lamp body 1 as the back, which is convenient for subsequent maintenance and repair. Since the lamp beads and lamp board are electrically connected in the sealed inner cavity space, both the lamp beads and lamp board will generate a certain amount of heat when the lamp beads are powered on. Several heat dissipation fins are also provided on the back of the lamp cover 2. The purpose of this design is to increase the heat dissipation area of the lamp cover 2. Since the street lights in the mountain top area of the scenic spot are turned on in the evening or early morning, and the temperature difference between day and night is large at the mountain top, the temperature of the surrounding air is lower as the time goes by. The heat in the inner cavity space, the heat conduction between the lamp cover 2, the lamp body 1 and the air, thus have a certain heat dissipation capacity.
[0032] To maintain nighttime lighting at the mountaintop and improve visitor convenience, the scenic area has maintenance personnel who regularly maintain the streetlights. However, the modular streetlights typically have lamp heads that are higher than human height, providing a wider illumination range. During maintenance, because the lamp head structure is suspended in the air, the lamp cover 2 is difficult to place after separating from the lamp body 1, hindering maintenance personnel's operation of the lamp panel. To address this, this embodiment features a flip-up connection between the lamp body 1 and the lamp cover 2. Specifically, limit pins 101 are fixed on both sides of the lamp body 1, and the lamp cover 2 has a vertical slide rail at the limit pins 101. The lamp cover 2 is slidably connected to the limit pins 101, allowing the lamp cover 2 to be vertically removed from the lamp body 1. The vertical slide rail is made of a deformable material with a certain degree of bending capability. The vertical slide can be bent to disengage it from the limiting pin 101. The lamp cover 2 can be flipped around the limiting pin 101. In addition, it should be noted that the lamp body 1 has a locking part 102 at one end where the limiting pin 101 is located. The locking part 102 has an outwardly protruding arc surface at the top and a groove at the bottom. Correspondingly, the lamp cover 2 is fixedly installed with a locking plate 201 above the locking part 102. The locking plate 201 is made of elastic material with an inwardly curved structure at the bottom, which has the ability to deform. Therefore, when the locking plate 201 contacts the arc surface of the locking part 102 of the lamp body 1, the locking plate 201 will deform to adapt. Then the inwardly curved structure of the locking plate 201 will be inserted into the groove to complete the locking. The locking plate 201 and the groove are fastened by deformation force, which not only realizes the fastening of the lamp body 1 and the lamp cover 2, but also facilitates the disassembly work during subsequent maintenance.
[0033] Existing lamp holder sealing structures mostly use simple rubber strips 321 or sealing gaskets for sealing. Elastic elements (rubber strips 321 or sealing gaskets) are placed on the contact surface between the lamp body 1 and the lamp cover 2 on the top or side. Their elastic deformation fills the gaps, achieving a certain sealing effect. This sealing method can prevent moisture and dust from entering to some extent, but it is difficult to disassemble and reassemble conveniently during maintenance. Therefore, a balance must be struck between easy disassembly and maintenance and sealing performance. For example, if the elastic element is placed on the top of the lamp body 1, during installation after maintenance, the entire lamp cover 2 needs to be evenly squeezed to ensure the entire lamp cover 2 is downward simultaneously. Uneven force can cause it to lift up, and inconsistent horizontal alignment between the lamp cover 2 and the lamp body 1 makes it difficult to fasten, hindering disassembly and reassembly. If the elastic element is placed on the side of the lamp body 1, uneven upward or downward force on the lamp cover 2 during disassembly and reassembly will cause excessive pressure on the elastic element, resulting in severe deformation and damage, affecting the sealing performance.
[0034] A retractable seal is provided at the joint between the lamp body 1 and the lamp cover 2. An arc groove is formed at the joint of the lamp body 1, encircling the outer surface of the lamp body 1. A sealing groove 31 is formed at the joint of the lamp cover 2, encircling the lower part of the lamp cover 2 along its inner side. The retractable seal is annular and movable within the sealing groove 31. A retaining strip 46 is located on the outer side of the lamp cover 2, with several sets of retaining strips 46 arranged along the edge of the lamp cover 2. One end of the retaining element is located at the sealing groove 31 at the joint of the lamp cover 2, and the other end passes through the lamp cover 2 and engages with the retaining strip 46. The number of retaining elements corresponds to the number of sets of retaining strips 46 and is located on the same... Vertical line; When the buckle and the clip 46 are engaged, the retractable seal disengages from the arc groove, releasing the seal; when the buckle and the clip 46 are disengaged, the retractable seal adheres to the arc groove through its own tensile force to achieve a seal; when the buckle and the clip 46 are disengaged, the retractable seal retracts through its own tensile force to re-adhere to the arc groove to achieve a seal. Through the tensile engagement of the buckle and the tensile characteristics of the retractable seal, the seal can be easily released during maintenance and disassembly, and automatically and quickly reset during installation, while also avoiding damage and detachment of the sealing ring or sealing strip 321.
[0035] Due to the high water molecule content in the air, a material capable of pressure deformation is necessary to achieve a seal and improve sealing performance. Therefore, the retractable seal includes a rubber sleeve 32 and a ring spring 33. The rubber sleeve 32 is placed inside the sealing groove 31. The rubber sleeve 32 is annular and hollow, and the ring spring 33 is located inside the rubber sleeve 32. The ring spring 33 is formed by spirally winding a spring wire into a ring. In the initial state, the ring spring 33 is squeezed from inside the rubber sleeve 32, causing the surface of the rubber sleeve 32 to fit tightly against the arc groove and the sealing groove 31, forming a seal. To prevent water molecules in the air from entering the inner cavity, the rubber sleeve 32 can "wrap" the contact surface through its own elastic deformation, increasing the effective sealing area and reducing local gaps caused by uneven contact surfaces. Additionally, the annular spring 33 can be stretched outwards like a rubber band or hair tie (i.e., expanding the circumference of the annular spring 33). Multiple sets of latches open the annular spring 33 at multiple points, causing the rubber sleeve 32 to disengage from the arc groove, releasing the seal. When the multiple sets of latches loosen, the annular spring 33, through its own elasticity, drives the rubber sleeve 32... 2. Synchronous retraction re-fits tightly with the arc groove to achieve a seal; in addition, the use of a rigid spring wire wound into a ring spring 33 has another function. Since the arc groove and sealing groove 31 are respectively opened on the separable lamp body 1 and lamp cover 2, when the lamp body 1 and lamp cover 2 are fastened, the arc groove and sealing groove 31 are combined, and the retractable seal is located between the arc groove and the sealing groove 31. When the lamp cover 2 is separated from the lamp body 1, the restriction of the retractable seal must be released. If the retractable seal is made entirely of flexible material, it will rely entirely on the elasticity of the retractable seal itself. The performance of the lamp cover 2 is subject to the squeezing and frictional forces, while the elastic performance of the retractable seal will inevitably decrease over time. Therefore, the uniform seal between the lamp cover 2 and the lamp body 1 will be unstable. Once the force that separates the lamp cover 2 from the lamp body 1 is greater than the squeezing and frictional forces of the retractable seal on the lamp cover 2, the lamp body 1 and the lamp cover 2 will easily separate. Therefore, the annular spring 33 is set inside the rubber sleeve 32. It can prevent excessive deformation of the rubber sleeve 32 through the rigid ring formed by its own spiral winding, thereby improving the fastening stability of the rubber sleeve 32 on the lamp cover 2 and the lamp body 1.
[0036] In addition, a triangular sponge ring 22 is provided on the inner side of the lamp cover 2. The size of the triangular sponge ring 22 is consistent with the triangular groove between the lamp body 1 and the lamp cover 2. Therefore, the triangular sponge ring 22 fits against the upper edge of the lamp body 1 as a second line of defense, further reducing the amount of moisture entering the inner cavity space between the lamp body 1 and the lamp cover 2.
[0037] The fastening components include a fixing rod 43, a limiting rod 44, a fastening plate 45, and an aluminum strip 42. Several semi-circular grooves are spaced apart on the upper surface of the sealing groove 31 near the arc groove. A fixing rod 43 is fixed to each semi-circular groove. Therefore, one end of the aluminum strip 42 is fixed to the fixing rod 43 as the head end. The aluminum strip 42 is made of flexible material and can be bent into shapes such as… Figure 7 or Figure 8 As shown, the aluminum strip 42 is in a sealed state, and a hollow cavity is provided in the middle of the hollow cavity. A limit rod 44 is placed in the hollow cavity. In addition, the lamp cover 2 is also provided with a notch 41 corresponding to several fasteners. The notch 41 is wider at the top and narrower at the bottom. The lower part of the aluminum strip 42 passes through the notch 41 and protrudes from the bottom of the lamp cover 2. The other end is fixed with a fastening plate 45. The fastening plate 45 is as follows: Figure 8 As shown, the upper part is connected to the aluminum strip 42, the middle part is a convex semi-circle for easy pulling by hand, and the lower part has a slot. In the sealed state, under the self-retracting force of the annular spring 33, the aluminum strip 42 bends to fit the arc groove. The limiting rod 44 at the cavity of the aluminum strip 42 is pulled out of the notch 41 to limit the rubber sleeve 32. The buckle plate 45 is stretched to contact the notch 41 on the outer side of the bottom of the lamp cover 2. When it is necessary to make the rubber sleeve 32 no longer fit and seal with the arc groove, the buckle plate 45 is pulled out, and the slot of the buckle plate 45 is inserted into the buckle strip 46. The buckle plate 45 pulls the aluminum strip 42, the limiting rod 44 falls into the notch 41, the aluminum strip 42 is straightened, and the aluminum strip 42 pushes the rubber sleeve 32 and the annular spring 33 to expand, thus releasing the seal.
[0038] Since the rubber sleeve 32 relies on the contraction force of the annular spring 33 to adhere to the arc groove in a linear fit, but because rubber is a high molecular polymer, it is easily affected by humidity, temperature changes (thermal expansion and contraction), or slight vibrations caused by wind. Therefore, under these conditions, the expansion of the rubber sleeve 32 may cause uneven distribution of contact pressure, and the linear fit may have tiny gaps, leading to a decrease in sealing performance. To address this, in this embodiment, the side of the rubber sleeve 32 that adheres to the arc groove is an annular surface, and the side away from the arc groove is a raised surface, with several rubber strips 321. The raised structure of the rubber strips 321 allows maintenance personnel to rotate the entire rubber sleeve 32 during the sealing process, turning one side of the raised rubber strips 321 towards the arc groove, so that several rubber strips 321 first contact the arc groove, and several rubber strips 321 then... 21 forms several isolation rings. Compared with the line bonding, several rubber strips 321 have a tighter contact with the arc groove. When compressed, the rubber strips 321 will compress first and "fill" the gap caused by the tolerance through their own elasticity. The rubber strips 321 are locally elastically reinforced to cope with assembly errors and dynamic environmental changes. It avoids the loss of compensation ability after the whole sponge is compacted. Therefore, it has better sealing performance in special situations. This design allows the sponge ring to switch between the ring surface and the raised surface. When the sealing of the ring surface decreases, the entire rubber ring can be rotated at a certain angle to combine the ring surface with part of the raised surface, so that both the raised surface and the ring surface are in contact with the arc groove. This ensures sealing performance while also having better durability (reducing aging caused by excessive compression) and adaptability. It is especially suitable for lighting scenarios that require dustproof and waterproof protection.
[0039] The working principle of this embodiment is as follows: Initially, the buckle plate 45 contacts the notch 41 at the bottom of the lamp cover 2. The retraction force of the ring spring 33 causes the rubber sleeve 32 to fit into the arc groove to achieve a seal and a uniform fastening. No additional buckles are needed at the seal point. When maintenance and disassembly are required, the maintenance personnel insert several buckle plates 45 into the buckle strip 46. When the buckle plate 45 is pulled, the aluminum strip 42 expands the rubber sleeve 32 and the ring spring 33, releasing the seal. There is no restriction between the lamp cover 2 and the lamp body 1. It can be directly and smoothly removed vertically. When installation is required after maintenance, several buckle plates 45 are pulled out from the buckle strip 46 and return to the initial sealed state under the retraction force of the ring spring 33.
