Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a housing structure and a lamp. Background Art

[0002] With the continuous innovation of lamp technology, the types of lamps applicable to different application scenarios are gradually increasing. For example, the lamp disclosed in the Chinese utility model patent document with the publication number CN220186728U belongs to a relatively novel type of outdoor lamp.

[0003] Lamps with a structure similar to the above generally have support feet connected by an axial connection method, which is used as a structure to support the lamp to maintain its position during use. When the lamp is folded, the support feet are exposed outside the lamp body. Therefore, they are easily damaged by external impacts. At the same time, the support feet outside the lamp body will also have a certain impact on the regularity of the lamp; even if a housing structure with a groove on the side wall of the fishing lamp disclosed in the Chinese utility model patent document with the publication number CN219473555U is used to solve the above problems, when using a large-size and long support foot to obtain a higher position fixing height during use, a single groove on the lamp body may not be able to provide enough storage space to store the support foot; in addition, the support feet on the above lamps can rotate around the position where the support feet are axially connected to the lamp housing. The relative movement of the support feet relative to the housing may cause the connection position between the support feet and the housing to become loose. Whether the lamp is in the unfolded or folded state, the loose support feet are prone to self-rotation when subjected to external forces, and the risk of damage to the support feet is relatively high. Summary of the Utility Model

[0004] In view of the technical defects existing in the background art, the utility model provides a housing structure and a lamp, which solve the above technical problems and meet the actual needs. The specific technical solutions are as follows:

[0005] The utility model discloses a housing structure, which includes a housing. The housing is formed by butting a first outer shell and a second outer shell. A plurality of first grooves are circumferentially arranged on the side wall of the first outer shell and are distributed along the length direction of the first outer shell. The first grooves penetrate through both ends of the first outer shell in the length direction. A plurality of second grooves are circumferentially arranged on the side wall of the second outer shell and are distributed along the length direction of the second outer shell. The second grooves and the first grooves are butted on the side wall of the housing to form a storage groove. A fitting groove is arranged on the wall surface outside one of the length direction ends of the first outer shell where the first groove is located. The central axis of the fitting groove is perpendicular to the central axis of the first groove. The end of the first groove close to the fitting groove is a narrowing part, and the width of the narrowing part is smaller than the width of the rest of the first groove.

[0006] As a further embodiment of the present utility model, the part of the first groove body near the narrowing part is a first concave part that is concave away from the axis of the first groove body, the end part of the second groove body far from the first groove body in the length direction is provided with a second concave part that is concave towards the center of the second outer shell, and the width of the first concave part is greater than the width of the remaining part of the first groove body.

[0007] As a further embodiment of the present utility model, the part of the first outer shell near the narrowing part is composed of two cover bodies, and the mating groove is formed by docking two grooves provided on the wall surfaces of the cover bodies close to the first groove body side.

[0008] As a further embodiment of the present utility model, the end wall surface of the second groove body far from the first groove body is an incomplete spherical surface.

[0009] As a further embodiment of the present utility model, both sides of the first groove body are transitioned to the outer wall surface of the first outer shell through bevels, and the edges of the second groove body are transitioned to the outer wall surface of the first outer shell through bevels.

[0010] The present utility model also discloses a lamp, which includes a support leg whose length can be changed by telescoping and the above-mentioned housing structure. One end of the support leg in the length direction is a connection part, one end of the connection part is located in the narrowing part and is provided with a shaft column that cooperates with the mating groove. The support leg realizes shaft connection with the housing structure through the cooperation between the shaft column and the mating groove, and the support leg rotates around the central axis of the shaft column and can be rotated into the receiving groove.

[0011] As a further embodiment of the present utility model, the other end of the connection part is located outside the narrowing part and can be rotated into the first concave part.

[0012] As a further embodiment of the present utility model, the other end of the support leg in the length direction is provided with a foot pad, the diameter of the foot pad is greater than the width of the part of the second groove body outside the second concave part, and the foot pad can support the support leg to rotate into the second concave part when driven.

[0013] The beneficial effects of the present utility model are:

[0014] After the first outer shell and the second outer shell in the housing structure are docked, a continuous storage groove is formed through the second groove body and the first groove body, providing more space for the overall storage of the support feet. When the lamp is not needed, it plays a role in protecting the support feet, preventing the support feet from being overly exposed to the outside and causing damage. It also makes the overall lamp more regular during storage. The matching groove provides a position for the shaft connection between the support feet and the housing structure to achieve the rotation of the support feet. In addition, the narrowing part on the storage groove can better hold the position of the support feet after they are screwed into the storage groove, preventing the support feet from rotating out of the storage groove under non-artificial traction, further protecting the support feet of the lamp, and preventing the connection position between the support feet and the housing structure from becoming loose. The position of the support feet after rotating outside the storage groove can be well maintained. Description of the Drawings

Detailed implementation manner

[0026] The present utility model discloses a housing structure, as Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 shown in combination, the housing structure includes a housing 1, the housing 1 is formed by docking a first outer shell 11 and a second outer shell 12, a plurality of first grooves 111 distributed along the length direction of the first outer shell 11 are circumferentially provided on the side wall of the first outer shell 11, the first grooves 111 penetrate through both ends in the length direction of the first outer shell 11, a plurality of second grooves 121 distributed along the length direction of the second outer shell 12 are circumferentially provided on the side wall of the second outer shell 12, the second grooves 121 and the first grooves 111 are docked on the side wall of the housing 1 to form a storage groove 2, a mating groove 21 is provided on the wall surface of the first outer shell 11 outside one end in the length direction of the first groove 111, the central axis of the mating groove 21 is perpendicular to the central axis of the first groove 111, the end of the first groove 111 close to the mating groove 21 is a narrowing portion 22, and the width of the narrowing portion 22 is smaller than the width of the rest of the first groove 111.

[0027] It should be noted that: This housing structure is a part of the housing 1 of a lamp with support feet 4. After the first housing 11 and the second housing 12 that make up this housing structure are docked, the first groove 111 and the second groove 121 are docked to form a receiving groove 2 that provides a position for the receiving of the support feet 4. When the lamp is not needed, the groove structures on both housings can provide space for the receiving of the support feet, enabling the entire support feet 4 to be received into the receiving groove 2, thereby playing a role in protecting the support feet 4 and preventing the situation where the support feet 4 are overly exposed to the outside and damaged. It can also make the overall lamp more regular during storage. The fitting groove 21 provides a position for the shaft connection between the support feet 4 and this housing structure. Since the position where the fitting groove 21 is located is at one end of the length direction of the first groove 111, and the first groove 111 runs through both ends of the first housing 11 in the length direction, after the support feet 4 are connected to this housing structure, the support feet 4 can rotate around the central axis of the fitting groove 21, and the rotation range of the support feet 4 is within 0° to 180° centered on the central axis of the fitting groove 21. Secondly, the setting of the narrowing portion 22 enables the part where the support feet 4 are shaft-connected to this housing structure to be screwed into the narrowing portion 22 when the support feet 4 rotate. By the contact between the wall surfaces on both sides of the narrowing portion 22 and the wall surfaces on both sides of the support feet 4, the frictional force is increased, so that the support feet 4 will not rotate out of the receiving groove 2 by themselves without artificial traction in the narrowing portion 22, playing a positioning role for the support feet 4 in the receiving groove 2. In addition, there will be no loose phenomenon at the connection position between the support feet 4 and this housing structure, and the position of the support feet 4 after rotation outside the receiving groove 2 can be well maintained.

[0028] Specifically, as Figure 1 , Figure 4 , Figure 5 and Figure 7 shown in combination, the part of the first groove 111 close to the narrowing portion 22 is a first recessed portion 23 that is recessed away from the axis of the first groove 111. The end of the second groove 121 far from the length direction of the first groove 111 is provided with a second recessed portion 24 that is recessed towards the center of the second housing 12. The width of the first recessed portion 23 is greater than the width of the rest of the first groove 111.

[0029] Since the diameters of some parts on the support feet 4 are larger than those of the rest, if the space size at the corresponding position of the storage groove 2 is the same as that of the rest, and the parts with larger diameters on the support feet 4 come into contact with the wall surface of the storage groove 2 first when being stored in the storage groove 2, it will cause the support feet 4 to not be stored straight into the storage groove 2, which has a certain impact on the flatness of the outer surface of the folded lamp. Therefore, the first recess 23 in the second groove body 121 can solve the above problems. The parts with larger diameters on the support feet 4 are stored at the corresponding positions on the first housing 11 through the first recess 23, and the first recess 23 has sufficient space and the width of the opening side, which is sufficient to allow the large-diameter parts corresponding to the position of the first groove body 111 in the support feet 4 to smoothly enter the storage groove 2 and be received by the storage groove 2. When the second recess 24 in the second groove body 121 stores the large-diameter parts on the support feet 4, the space formed by its depression towards the center of the second housing 12 can provide a storage space for the large-diameter parts on the support feet 4, so that the part of the storage groove 2 on the second housing 12 can store the large-diameter parts on the support feet 4. Through the settings of the first recess 23 and the second recess 24, the outer surface of the folded lamp can have better flatness, making the shape of the lamp more beautiful. The support feet 4 stored straight into the storage groove 2 can reduce the situation that the support feet 4 are screwed out of the storage groove 2 under the action of external forces when they are not manually rotated and unfolded for work, and play a certain protective role for the support feet 4 in the folded state.

[0030] Specifically, as Figure 3 shown, the part of the first housing 11 close to the narrowing part 22 is composed of two cover bodies 13, and the fitting groove 21 is formed by butting two grooves 211 provided on the wall surfaces of the cover bodies 13 close to the first groove body 111 side.

[0031] Among them, when the two cover bodies 13 are installed at the end of the first housing 11, one of the cover bodies 13 can be installed at the end of the first housing 11 first, then the part of the support feet 4 that forms a shaft connection with the housing structure is installed at the groove 211, and then the other cover body 13 is installed, so that the two grooves 211 are butted to form a fitting groove 21 that limits the outside of the shaft connection end of the support feet 4 and the housing structure, making the operation of assembling the support feet 4 to the housing structure simpler and conducive to improving the assembly efficiency of the lamp.

[0032] Specifically, as Figure 1 、 Figure 5 and Figure 7 shown in combination, the end wall surface of the second groove body 121 away from the first groove body 111 is an incomplete spherical surface.

[0033] If the support leg 4 does not occupy the entire space of the second groove body 121 after being retracted into the storage groove 2, and the end of the second groove body 121 away from the first groove body 111 is a non-through structure of the second housing 12 and the support leg 4 does not occupy all the space of the second groove body 121, the space at the end of the second groove body 121 away from the first groove body 111 can allow the user's finger to extend in, so as to facilitate the traction of the support leg 4 retracted into the storage groove 2; in addition, the end wall surface of the second groove body 121 away from the first groove body 111 is an incomplete spherical surface, and the contour is similar to the fingertip part of a person, making this position in the second groove body 121 better adapt to the insertion operation of fingertips of different sizes, and making it easier for the user to traction the support leg 4.

[0034] Specifically, as Figure 6 and Figure 7 Combined with the shown, both sides of the first groove body 111 transition to the outer wall surface of the first housing 11 through the bevel 3, and the edges of the second groove body 121 transition to the outer wall surface of the first housing 11 through the bevel 3.

[0035] Among them, the bevel 3 can guide the support leg 4 screwed into the first groove body 111 and the second groove body 121, so that the support leg 4 can more easily enter the storage groove 2 for storage, and the storage operation of the support leg 4 is smoother.

[0036] The present utility model also discloses a lamp, as Figures 8 - 10 Combined with the shown, it includes a support leg 4 whose length can be changed by telescoping and the above-mentioned housing structure. One end of the support leg 4 in the length direction is a connecting portion 41. One end of the connecting portion 41 is located in the narrowing portion 22 and is provided with a shaft column 42 that cooperates with the mating groove 21. The support leg 4 realizes shaft connection with the housing structure through the cooperation between the shaft column 42 and the mating groove 21, and the support leg 4 rotates around the central axis of the shaft column 42 and can rotate into the storage groove 2.

[0037] It should be noted that the support feet 4 configured on the lamp with this housing structure can be fitted with the mating groove 21 through the shaft column 42 on the connecting portion 41. Specifically, during the assembly of the lamp, after one cover body 13 is installed at the end of the first outer shell 11, the support feet 4 are inserted along the direction in which the shaft column 42 mates with the groove 211 on one of the cover bodies 13. After the other cover body 13 is installed, the two grooves 211 are butted to form the mating groove 21 that fits outside the shaft column 42, thus realizing the shaft connection between the support feet 4 and this housing structure, and further realizing the rotation of the support feet 4, enabling the support feet 4 to rotate around the central axis of the shaft column 42 into the storage groove 2 for storage. When the lamp is in use, it can also rotate around the central axis of the shaft column 42 to the lower part of the lamp to form a structure for supporting the lamp, so as to maintain the position stability of the lamp during use. In addition, since the connecting portion 41 is located within the narrowing portion 22, when the support feet 4 rotate, the friction between the connecting portion 41 and the surface of the narrowing portion 22 is relatively large, so that the position where the support feet 4 are shaft-connected to this housing structure has good position-holding ability, and the support feet 4 can only rotate under manual traction, and non-manual operation will not affect the folded and unfolded states of the lamp.

[0038] Specifically, as Figure 9 and Figure 10 shown in combination, the other end of the connecting portion 41 is located outside the narrowing portion 22 and can rotate into the first recess 23.

[0039] Since the joint part of the support feet 4 is usually the connection position of two or more component parts, the diameter sizes of other positions of the support feet 4 are relatively smaller than the diameter size of this position. Therefore, the setting of the first recess 23 can provide more space for the joint part of the support feet 4 when they are stored in the storage groove 2 for storage, so that the support feet 4 can be stored straight into the storage groove 2. While making the outer surface of the folded lamp more regular, it can also reduce the possibility that the support feet 4 are screwed out of the storage groove 2 under the action of external forces when they are not rotated and unfolded manually for work.

[0040] Specifically, as Figure 9 and Figure 10 shown in combination, the other end in the length direction of the support feet 4 is provided with a foot pad 5. The diameter of the foot pad 5 is greater than the width of the part of the second groove body 121 outside the second recess 24, and the foot pad 5 can be rotated to the second recess 24 under the drive of the support feet 4.

[0041] Among them, the diameter of the foot pad 5 is greater than the width of the second groove body 121 outside the second recess 24, so that when the support leg 4 is screwed into the storage groove 2, an interference fit relationship will be formed between the foot pad 5 and the storage groove 2, which plays a certain role in maintaining the position of the support leg 4 in the storage groove 2; similarly, since the foot pad 5 is set at the end of the support leg 4, which belongs to the connection position of the component parts, the diameter of this position is larger than the diameter of the other positions of the support leg 4. Therefore, the setting of the second recess 24 can provide more space for the end of the support leg 4 when it is stored in the storage groove 2, so that the support leg 4 can be stored straight in the storage groove 2. While making the outer surface of the folded lamp more regular, it can also reduce the possibility that the support leg 4 is screwed out of the storage groove 2 under the action of external force when it is not manually rotated and unfolded for work.

[0042] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
