TECHNICAL FIELD
[0001] The utility model relates to the technical field of lamps, in particular to a buried lamp. BACKGROUND
[0002] The buried lamp is a lighting facility embedded on the ground, mainly used for illuminating the ground, ground vegetation and the like, so as to make the landscape more beautiful and the pedestrians safer. When installing the buried lamp, a hole is first opened on the ground and a wire is threaded, then a waterproof cylinder is installed in the hole, and finally the buried lamp is installed in the waterproof cylinder.
[0003] The existing buried lamp is mostly of fixed structure, which cannot adjust the irradiation angle after installation and cannot light the specific direction of the scenery. Even the buried lamp with adjustable angle structure also needs to cooperate with an external rotating frame, and the position of the lamp needs to be adjusted in angle after loosening the bolt first, and the bolt needs to be tightened after the angle adjustment is completed. Not only the operation is troublesome, but also the setting of the rotating frame occupies a large space position, resulting in that the volume of the buried lamp is too large, and various costs are also high. SUMMARY
[0004] The utility model aims at providing a small volume and angle adjustment buried lamp.
[0005] The buried lamp according to the first aspect of the utility model comprises:
[0006] A lamp shell is provided with a lamp shade at the top, and an accommodating cavity is arranged in the inside of the lamp shell;
[0007] A light emitting assembly is rotatably connected in the accommodating cavity through a rotating shaft at the side, the light emitting assembly is provided with a light emitting element facing the lamp shade, the light emitting assembly is provided with a threaded hole away from the rotating shaft in the axial direction, and a fixing hole penetrating to the threaded hole is arranged at the top of the light emitting assembly; the side of the lamp shell is provided with a mounting hole opposite to the threaded hole;

[0009] According to the underground lamp, the following beneficial effects are achieved: during assembly, the relative position between the adjusting bolt and the light-emitting assembly can be initially positioned due to the threaded hole of the light-emitting assembly for the threaded connection of the adjusting bolt, and then the synchronous connection of the adjusting bolt and the light-emitting assembly is realized through the fixing part, so that the light-emitting assembly can rotate together with the adjusting bolt when the adjusting bolt is rotated on the surface of the lamp shell, thereby realizing the angle adjustment function of the underground lamp; compared with the prior art, the rotating frame is not required, so that the volume of the underground lamp can be smaller, and the operation process of angle adjustment is also more simple.
[0010] According to some embodiments of the present application, the fixing hole is filled with an adhesive and forms an adhesive layer, a fixing bolt is threadedly connected to the fixing hole, the fixing bolt penetrates into the adhesive layer, and the fixing bolt and the adhesive layer jointly constitute the fixing part. If only the adhesive is used, the torque of the adjusting bolt is entirely transmitted to the adhesive layer, the rigidity of the adhesive layer is poor, and therefore the fixing bolt needs to be additionally increased to improve the rigidity of the fixing part and avoid synchronous failure due to excessive torque.
[0011] According to some embodiments of the present application, the adjusting bolt is provided with a fixing screw hole, the fixing screw hole has a movement path opposite to the fixing hole, the fixing part is a fixing bolt, and the fixing bolt is threadedly connected to the fixing screw hole. The fixing bolt has good rigidity and can well transmit torque, thereby realizing the synchronous movement of the adjusting bolt and the light-emitting assembly.
[0012] According to some embodiments of the present application, in order to quantify the adjustment angle, the surface of the adjusting bolt is provided with an indication mark, and the lamp shell is provided with an angle mark beside the indication mark. When the indication mark points to a specific number of the angle mark, the adjustment angle of the light-emitting assembly is the value at this time.
[0013] According to some embodiments of the present application, in order to meet the waterproof requirement, a waterproof sleeve extending to the accommodating cavity is arranged in the mounting hole, and the adjusting bolt penetrates through the waterproof sleeve and is threadedly connected to the threaded hole.
[0014] According to some embodiments of the present application, a plurality of sealing rings are connected to the adjusting bolt in the waterproof sleeve, so as to avoid the penetration of rainwater into the accommodating cavity from the gap between the adjusting bolt and the waterproof sleeve.
[0015] According to some embodiments of the utility model, in order to limit the radial position of the light emitting assembly in the accommodating cavity, the waterproof sleeve is sleeved with a limiting sleeve, and the limiting sleeve is in abutment with the inner side wall of the lamp shell and the outer side wall of the light emitting assembly. At the same time, if the limiting sleeve is selected as a rubber sleeve, when the adjusting bolt is threadedly connected to the threaded hole and the limiting sleeve is subjected to pressure, the limiting sleeve will generate an elastic pre-pressure, which can hinder the rotation of the light emitting assembly to a certain extent, thereby maintaining the current rotation position of the light emitting assembly.
[0016] According to some embodiments of the utility model, specifically, the adjusting bolt comprises a screw head, a light rod and a screw rod arranged in sequence, the size of the screw head is larger than that of the light rod, the surface of the screw head is provided with a spanner hole, and the screw rod is threadedly connected to the threaded hole. The user needs to use a specific spanner to rotate the screw head, and then rotate the entire adjusting bolt.

[0018] According to some embodiments of the utility model, a spring washer is arranged between the screw head and the shallow hole. When the adjusting bolt is threadedly connected to the threaded hole and the spring washer is subjected to pressure, the spring washer will generate a rebound force, which can hinder the rotation of the light emitting assembly to a certain extent, thereby maintaining the current rotation position of the light emitting assembly.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.
[0032] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0033] like Figures 1 to 4 As shown, the in-ground lamp according to a first aspect embodiment of the present invention includes a lamp housing 100, a light-emitting component 200, and a drive controller 300. The lamp housing 100 includes a lampshade 110, a housing 120, and a bottom cover 130. The housing 120 has a receiving cavity 101. Both the top and bottom ends of the housing 120 have openings communicating with the receiving cavity 101. The lampshade 110 is sealed to the opening at the top end, and the bottom cover 130 is sealed to the opening at the bottom end, together forming an internally sealed lamp housing 100. To meet power supply requirements, the bottom cover 130 has a wiring hole in the middle, with a waterproof gland 311 on the wiring hole. A cable 310, electrically connected to the drive controller 300, extends from the gland 311 to the outside of the lamp housing 100. The main body of the lampshade 110 is a glass plate 111, through which light is scattered from the inside of the receiving cavity 101 to the external environment.
[0034] To further enhance waterproof and moisture-proof performance, the lampshade 110, housing 120, and bottom cover 130 are bonded together with waterproof adhesive to form a complete structure. Compared to traditional screw assembly methods, this embodiment effectively improves waterproof and moisture-proof performance and prevents screws from rusting or being loosened by others, thus ensuring the normal use of the in-ground light. When the in-ground light malfunctions, maintenance personnel replace the damaged one with a brand new one, and the damaged light is taken to the repair room for repair, thereby improving the quality of after-sales service.
[0035] Of course, the installation of other accessories needs to be completed before the lampshade 110, housing 120 and bottom cover 130 are glued together with waterproof adhesive.
[0036] On the other hand, the structure of the light emitting assembly 200 is not improved in the embodiment, and the light emitting assembly 200 can use the existing structure. The light emitting assembly 200 is provided with a light emitting element 210 facing the lampshade 110. The light emitting element 210 can be an LED lamp, a halogen lamp or an incandescent lamp. Since the power consumption and heat generation of the LED lamp are less, and the luminous flux is higher, the LED lamp is the preferred embodiment.
[0037] Specifically, the side of the light emitting assembly 200 is provided with a first rotating hole 220. Correspondingly, the inner side wall of the shell 120 is provided with a second rotating hole 121 opposite to the first rotating hole 220. The first rotating hole 220 and the second rotating hole 121 are provided with a rotating shaft 400. The rotating shaft 400 has a stepped structure. The two ends of the rotating shaft 400 are smaller in size and are respectively used to extend into the first rotating hole 220 and the second rotating hole 121. The middle part of the rotating shaft 400 is larger in size and is larger than the size of the first rotating hole 220 and the second rotating hole 121. Therefore, the light emitting assembly 200 and the shell 120 not only have the freedom of relative rotation through the rotating shaft 400, but also can limit the minimum distance between the light emitting assembly 200 and the shell 120 through the rotating shaft 400.
[0038] In addition, the side of the light emitting assembly 200 is provided with a threaded hole 230 on the other side of the first rotating hole 220. The threaded hole 230 is coaxial with the first rotating hole 220, and the threaded hole 230 is located away from the rotating shaft 400. The top of the light emitting assembly 200 is provided with a fixing hole 240 penetrating into the threaded hole 230. In the embodiment, the threaded hole 230 and the first rotating hole 220 are arranged in the horizontal direction, and the fixing hole 240 is arranged in the vertical direction. However, the specific arrangement direction of the threaded hole 230 and the fixing hole 240 is not limited in the utility model. As long as the threaded hole 230 and the fixing hole 240 are not coaxially arranged, no matter what direction they are arranged in, they all belong to the protection scope of the utility model.
[0039] Correspondingly, the side of the shell 120 is provided with a mounting hole 122 opposite to the threaded hole 230. The mounting hole 122 is used to penetrate the adjusting bolt 500 from the outside to the inside. The threaded rod 530 of the adjusting bolt 500 is threadedly connected with the threaded hole 230 of the light emitting assembly 200. After the threaded connection of the adjusting bolt 500 and the threaded hole 230 is completed, the fixing part 241 can be introduced into the fixing hole 240. The fixing part 241 is used to be connected with the adjusting bolt 500. If the fixing part 241 and the adjusting bolt 500 are connected together, even if only the adjusting bolt 500 is rotated, the adjusting bolt 500 can also transmit the torque to the fixing part 241. The fixing part 241 transmits the torque to the light emitting assembly 200, and then the synchronous connection of the adjusting bolt 500 and the light emitting assembly 200 is realized through the fixing part 241.
[0040] That is to say, before the fixed part 241 is set, even if the adjusting bolt 500 is rotated, the adjusting bolt 500 only keeps the threaded connection relationship with the threaded hole 230, once the fixed part 241 is set, the connection relationship between the adjusting bolt 500 and the light emitting assembly 200 is changed, at this time, the two become a rotating community, as long as the adjusting bolt 500 is rotated, the light assembly also rotates along with the adjusting bolt 500, which provides a technical basis for controlling the angle of the light assembly on the surface of the lamp shell 100.
[0041] In some embodiments of the present application, the adjusting bolt 500 comprises a screw head 510, a light rod 520 and a screw rod 530 arranged in sequence, the size of the screw head 510 is larger than that of the light rod 520, and the screw rod 530 has a threaded connection relationship with the threaded hole 230. The surface of the screw head 510 is provided with a wrench hole 511 and an indication mark 512, the wrench hole 511 can be selected as a regular triangular hole, a square hole or a regular hexagonal hole, and the indication mark 512 is a directional graphic mark, and the operator can determine the current rotating position of the adjusting bolt 500 according to the direction of the graphic mark.
[0042] As shown in Figure 4 and Figure 5 , in order to realize the connection between the fixed part 241 and the adjusting bolt 500, after the adjusting bolt 500 is threaded into the threaded hole 230, an adhesive is poured into the fixed hole 240 to form an adhesive layer, and then the fixed hole 240 is also threaded with a fixed bolt, and the fixed bolt is deep into the adhesive layer before the adhesive solidifies. After the adhesive solidifies, the fixed bolt and the adjusting bolt 500 form an integral whole under the adhesion of the adhesive, at this time, the fixed bolt and the adhesive layer jointly constitute the fixed part 241. When the adjusting bolt 500 is rotated, the adjusting bolt 500 transmits the torque to the fixed part 241, the fixed part 241 transmits the torque to the light emitting assembly 200, and then realizes the synchronous connection of the adjusting bolt 500 and the light emitting assembly 200 through the fixed part 241.
[0043] It should be noted that if the adhesive is used alone, the torque of the adjusting bolt 500 will be transmitted to the adhesive layer, and the rigidity of the adhesive layer is poor, which is easy to lose the adhesion of the adjusting bolt 500 after being stressed, so the fixed bolt is additionally increased to improve the rigidity of the fixed part 241, so as to avoid the synchronous failure caused by excessive torque.
[0044] Although in the present embodiment, the fixed hole 240 can also be provided as a light hole, that is, the fixed bolt is not threaded with the fixed hole 240, but such arrangement cannot limit the fixed bolt to the preset position, which has the possibility of floating in the adhesive.
[0045] As shown in Figure 1 and Figure 3As shown in some embodiments of the present utility model, in order to quantify the adjustment angle, in addition to the indication mark 512 on the surface of the screw head 510, the shell 120 is also provided with an angle mark 123 beside the indication mark 512, and the angle mark 123 has a range of -20° to +20° according to the requirement of the adjustment angle. When correcting, first screw the adjusting bolt 500 into the threaded hole 230, because the connection between the adjusting bolt 500 and the threaded hole 230 is threaded connection at this time, so the rotation of the adjusting bolt 500 will not affect the irradiation angle of the light emitting assembly 200, then rotate the indication mark 512 of the adjusting bolt 500 to point to the 0° position of the angle mark 123, and finally realize the synchronous connection of the adjusting bolt 500 and the light emitting assembly 200 through the fixing part 241.
[0046] When the light emitting assembly 200 needs to be adjusted to +5° angle, only need to use the wrench to rotate the wrench hole 511 of the adjusting bolt 500, and make the indication mark 512 of the adjusting bolt 500 point to the +5° position of the angle mark 123; when the light emitting assembly 200 needs to be adjusted to -10° angle, only need to use the wrench to rotate the wrench hole 511 of the adjusting bolt 500, so that the indication mark 512 of the adjusting bolt 500 points to the -10° position of the angle mark 123.
[0047] As shown in some embodiments of the present utility model, Figure 6 and Figure 7 As shown in some embodiments of the present utility model, in order to realize the connection between the fixing part 241 and the adjusting bolt 500, the screw rod 530 of the adjusting bolt 500 is provided with a fixed screw hole 531, and the fixed screw hole 531 has a movement path opposite to the fixed hole 240, at this time the fixing part 241 is only a fixed bolt. When the fixed screw hole 531 of the adjusting bolt 500 is opposite to the fixed hole 240, the fixed bolt enters the fixed hole 240 and is screwed in the fixed screw hole 531, so as to form a whole with the fixed bolt and the adjusting bolt 500. When rotating the adjusting bolt 500, the adjusting bolt 500 transmits the torque to the fixed bolt, and the fixed bolt transmits the torque to the light emitting assembly 200, and then realizes the synchronous connection of the adjusting bolt 500 and the light emitting assembly 200 through the fixed bolt. The fixed bolt has good rigidity, which can well transmit the torque, and then realize the synchronous movement of the adjusting bolt 500 and the light emitting assembly 200.
[0048] It should be noted that since the position of the screw 530 of the adjusting bolt 500 in the threaded hole 230 is difficult to observe with the naked eye, the rotation angle of the adjusting bolt 500 in the threaded hole 230 needs to be determined according to the indicator mark 512 on the screw head 510. During installation, first screw the screw 530 of the adjusting bolt 500 into the threaded hole 230. After screwing it into the approximate position, observe the position of the screw 530 through the fixing hole 240, and rotate the adjusting bolt 500 according to the indicator mark 512, so that the fixing screw hole 531 of the adjusting bolt 500 is aligned with the fixing hole 240. After this, use a magnetic wrench to push the fixing bolt into the fixing hole 240, and apply torque after the fixing bolt reaches the fixing screw hole 531, thereby threading the fixing bolt into the fixing screw hole 531.
[0049] Furthermore, since the fixing bolt is threaded to the fixing screw hole 531, in order to avoid interference, in this embodiment, the fixing hole 240 is no longer provided with an internal thread for threaded connection with the fixing bolt, that is, the fixing hole 240 is a smooth hole.
[0050] like Figures 3 to 5 As shown, in some embodiments of this utility model, to meet the waterproofing requirements, a waterproof sleeve 600 extending into the receiving cavity 101 is provided in the mounting hole 122. The adjusting bolt 500 passes through the waterproof sleeve 600 from the outside to the inside and is threadedly connected to the threaded hole 230. The waterproof sleeve 600 includes a head 610 and a rod 620. Given the structure of the adjusting bolt 500, the size of the head 610 of the waterproof sleeve 600 is larger than the size of its rod 620. The head 610 has a shallow hole 611 for accommodating the screw head 510, and the rod 620 has a deep hole 621 for accommodating the smooth rod 520. The shallow hole 611 and the deep hole 621 together constitute a second countersunk hole. Correspondingly, since the waterproof sleeve 600 needs to pass through the mounting hole 122, the mounting hole 122 is a first countersunk hole. The countersunk hole ensures that the screw head 510 remains flush with the outer wall of the housing 120, preventing any protrusion.
[0051] Specifically, the smooth rod 520 of the adjusting bolt 500 is provided with several annular grooves, and each annular groove is provided with a sealing ring 630. The sealing ring 630 is in contact with the smooth rod 520 and the deep hole 621 respectively, so as to prevent rainwater from seeping into the receiving cavity 101 from the gap between the adjusting bolt 500 and the waterproof sleeve 600.
[0052] In some embodiments of the utility model, in order to limit the radial position of the light emitting assembly 200 in the accommodating cavity 101, the waterproof sleeve 600 is sleeved with a limiting sleeve 700 outside, and the limiting sleeve 700 is in abutment with the inner side wall of the shell 120 and the outer side wall of the light emitting assembly 200 respectively. The limiting sleeve 700 can be selected as a rigid sleeve or a rubber sleeve. When the adjusting bolt 500 is screwed into the threaded hole 230 and continues to be tightened, the light emitting assembly 200 moves in the direction of the mounting hole 122 under the action of the adjusting bolt 500 until the light emitting assembly 200 is in abutment with the limiting sleeve 700. With the continuous tightening of the adjusting bolt 500, the limiting sleeve 700 will be subjected to pressure from the light emitting assembly 200, at which time the limiting sleeve 700 will generate a rebound force, which can hinder the rotation of the light emitting assembly 200 to a certain extent. That is to say, after the light emitting assembly 200 is adjusted to a specified angle, the rebound force of the limiting sleeve 700 can maintain the current rotational position of the light emitting assembly 200, avoiding the autonomous rotation of the light emitting assembly 200 without external force. Of course, when the adjusting bolt 500 is rotated, the operator also needs to overcome the rebound force to make the adjusting bolt 500 rotate.
[0053] In some embodiments of the utility model, a spring washer 800 is arranged between the screw head 510 and the shallow hole 611. When the adjusting bolt 500 is screwed into the threaded hole 230 and continues to be tightened, the light emitting assembly 200 moves in the direction of the mounting hole 122 under the action of the adjusting bolt 500 until the light emitting assembly 200 is in abutment with the limiting sleeve 700. With the continuous tightening of the adjusting bolt 500, the adjusting bolt 500 drives the waterproof sleeve 600 to move in the direction of the threaded hole 230, and the spring washer 800 will be subjected to pressure from the screw head 510, at which time the spring washer 800 will generate an elastic pre-pressure, which can hinder the rotation of the light emitting assembly 200 to a certain extent, thereby maintaining the current rotational position of the light emitting assembly 200, avoiding the autonomous rotation of the light emitting assembly 200 without external force. Of course, when the adjusting bolt 500 is rotated, the operator also needs to overcome the elastic pre-pressure to make the adjusting bolt 500 rotate.
[0054] It needs to be further explained that, after the spring washer 800 is arranged, the limiting sleeve 700 is preferably a rigid sleeve to avoid the situation of being subjected to force from both ends.
[0055] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by ordinary skilled persons in the technical field without departing from the purpose of the utility model.
