[0002] Nowadays, outdoor activities have become one of the most popular ways of entertainment for people during holidays. When conducting outdoor activities at night, people usually equip themselves with portable outdoor lamps to facilitate their movements at night. In some cases, outdoor lamps need to be used with tripods to position and place the lamps.

[0003] For example, a fishing lamp disclosed in Chinese utility model patent with publication number CN219473555U forms a tripod structure under the lamp by rotating the supporting legs. However, after the tripod of the lamp with this structure is unfolded, if the rotating end of the supporting legs is not effectively fixed, the supporting legs are prone to self-rotation, thereby affecting the supporting effect of the tripod on the lamp. When the stability of the tripod is defective, the position of the lamp will shift, thereby affecting its normal lighting. In severe cases, the lamp may even topple over as a whole, causing damage to the lamp and the tripod. In addition, the tripod structure used on some outdoor lamps requires the supporting legs on the tripod to be connected in a tightly connected manner, which makes it inconvenient for the user to unfold or fold the supporting legs on the tripod, and the tripod cannot be quickly unfolded or folded.

DETAILED DESCRIPTION

[0035] The utility model discloses a lamp stand lock structure, such as Figures 1 to 7 As shown in combination, the tripod lock structure is used to limit the support foot 7 in the tripod 20, including a lock 1 and a connecting seat 2, the center of the connecting seat 2 is provided with a cavity 3 for accommodating the lock 1, the middle of the cavity 3 is provided with a connecting portion 4, the lock 1 is rotated in the cavity 3 by cooperating with the connecting portion 4, the edge of the lock 1 is a plurality of limiting portions 5 arranged at equal intervals in the circumferential direction, the connecting seat 2 is circumferentially provided with a plurality of matching grooves 6 located outside the cavity 3 and connected to the cavity 3, one end of the support foot 7 is connected to the matching groove 6 by an axial connection, and the end wall surface of the support foot 7 located in the matching groove 6 is provided with a clamping groove 8; as shown in FIG. Figure 4As shown, when the engaging groove 8 can be moved to a position facing the cavity 3 in the matching groove 6 by the rotation of the supporting foot 7, the limiting portion 5 can be moved to the engaging groove 8 by the rotation of the locking member 1 to limit the supporting foot 7; Figure 5 As shown, the limiting portion 5 is moved out of the engaging groove 8 by the rotation of the locking member 1 and the limiting of the supporting foot 7 is released. The engaging groove 8 can be moved to a position in the matching groove 6 that is not directly opposite to the cavity 3 by the rotation of the supporting foot 7.

[0036] It should be noted that when the tripod 20 is needed to support the lamp, firstly, a plurality of supporting legs 7 are rotated to the space below the lamp with the ends of the supporting legs 7 connected to the matching grooves 6 as the rotation center to form the supporting parts of the tripod 20. When the supporting legs 7 rotate, the engaging grooves 8 on the supporting legs 7 are directly opposite to the positions of the matching grooves 6. After the tripod 20 on the lamp is unfolded, the locking member 1 in the tripod lock structure can rotate its limiting portion 5 to the engaging grooves 8 of the supporting legs 7, so as to limit the supporting legs 7 rotated to form the tripod 20 below the lamp. By limiting the end positions of the supporting legs 7 connected to the shafts on the lamp body, the tripod 20 can be formed. The position of the supporting foot 7 remains unchanged to achieve the purpose of maintaining the stability of the tripod 20; and when the tripod 20 is no longer needed to support the lamp, after the limiting portion 5 is moved out of the clamping groove 8 of the supporting foot 7 by rotating the lock 1, the limiting portion 5 no longer limits the end of the supporting foot 7 connected to the matching groove 6, and the supporting foot 7 can be rotated again with the end of its axis connected to the matching groove 6 as the rotation center, so as to rotate to the top of the connecting seat 2 for folding; the tripod lock structure has fewer components and a simple structure. When locking and unlocking the supporting foot 7, it only needs to control the position of the limiting portion 5 by rotating the lock 1, which is relatively convenient to operate.

[0037] As a further preference of the above embodiment, Figure 4 and Figure 5 As shown in the combination, a clearance groove 9 is formed between two adjacent limiting portions 5 in the circumferential direction of the lock 1; when the limiting portion 5 limits the supporting foot 7, the clearance groove 9 is located in the space of the cavity 3 which is not directly opposite to the matching groove 6; when the clearance groove 9 is directly opposite to the matching groove 6, the supporting foot 7 can rotate.

[0038] Among them, when the clearance groove 9 is located in the space of the cavity 3 that is not directly opposite to the matching groove 6, the end of the support leg 7 shaft connected to the matching groove 6 is restricted by the limiting portion 5 and cannot obtain rotation space in the cavity 3 and the matching groove 6; when the clearance groove 9 is directly opposite to the matching groove 6, the end of the support leg shaft connected to the matching groove 6 is no longer restricted by the limiting portion 5, so that it can move in the cavity 3 and the matching groove 6, and then the support leg 7 can be rotated to realize the movement of expanding or folding the support leg 7 to the outside of the lamp.

[0039] As a further preference of the above embodiment, Figure 2 , Figure 3 and Figure 6 As shown in combination, the connecting seat 2 is composed of a first shell 10 and a second shell 11, the cavity 3 is located in the middle of one of the axial ends of the first shell 10, and the second shell 11 is fitted outside the end of the first shell 10 close to the cavity 3. The connecting portion 4 includes a protrusion 12 with a circular cross-section and a limit block 14. The protrusion 12 is arranged at the center of the cavity 3, and a matching hole 13 is provided at the center of the lock 1. The lock 1 is connected to the first shell 10 through the matching hole 13 and the protrusion 12. A plurality of limit blocks 14 with arc-shaped edges and an outer diameter equal to the diameter of the matching hole 13 are circumferentially provided on the middle surface of the second shell 11, and the limit blocks 14 are fitted in the matching hole 13.

[0040] Among them, when assembling the tripod lock structure, the lock component 1 is first installed in the cavity 3 along the direction of the matching hole 13 and the protrusion 12 to achieve the connection between the lock component 1 and the first shell 10, and then the second shell 11 is installed to the end of the first shell 10 close to the cavity 3 along the direction of the matching block 14 and the matching hole 13 to achieve the connection between the first shell 10 and the second shell 11, and the cavity 3 is closed, thereby forming a structure in which the lock component 1 is matched in the cavity in the connecting seat 2. Through the matching of the protrusion 12 and the limiting block 14 with the matching hole 13, the lock component 1 can be rotated with the center of the matching hole 13 as the rotation center. The assembly process of the tripod lock structure is simple and can meet the assembly requirements during mass production.

[0041] As a further preference of the above embodiment, Figures 4 to 6 As shown in the figure, the connecting seat 2 outside one side of the cavity 3 is provided with an extension channel 15, and the extension channel 15 extends outward from one side of the cavity 3 and is connected with the space outside the connecting seat 2. One end of the limiting portion 5 is provided with a force arm 16 passing through the extension portion, and the end of the force arm 16 away from the limiting portion 5 is provided with a driving block 17 located outside the connecting seat 2.

[0042] Among them, the lock 1, the force arm 16 and the drive block 17 are connected as one body by using the force arm 16 connected between the drive block 17 and the lock 1. When the drive block 17 is pushed by the finger to move in the circumferential direction of the connecting seat 2, the force arm 16 will move in the extension channel 15, and the lock 1 will also rotate accordingly; when the drive block 17 is outside the two ends of the extension channel 15, it represents that the support foot 7 is in the locked and unlocked states respectively.

[0043] Preferably, Figure 5 and Figure 6As shown in the figure, at least two protrusions 18 are provided on the surface of the connection seat 2 in the extension channel 15 . The protrusions 18 are located at two ends of the circumferential range of the extension channel 15 and are spaced apart from the wall surface of the connection seat 2 outside the extension channel 15 .

[0044] Among them, when the driving block 17 is outside the two ends of the extension channel 15, the force arm 16 in the extension channel 15 is also located at the two ends of the extension channel 15, and the protrusion 18 will limit the force arm 16 in the extension channel 15, and restrict it between the protrusion 18 and the end wall of the extension channel 15. Even if the locking member 1, the force arm 16 and the driving block 17 connected as one are subjected to external force, there will be no position movement, ensuring that the locking and unlocking of the supporting foot 7 by the tripod lock structure will not be switched without human operation, thereby improving the working stability of the tripod lock structure.

[0045] As a further preference of the above embodiment, Figure 1 , Figure 3 and Figure 8 As shown in the figure, the end wall surfaces at both ends of the limiting portion 5 and the end wall surfaces of the supporting foot 7 outside the two sides of the clamping groove 8 are all provided with bevel angles 31 for guiding.

[0046] Among them, if it is necessary to limit the rotational movement of the rotating end of the supporting foot 7, the limiting part 5 needs to be moved into the clamping groove 8. When the clamping groove 8 is rotated to a position close to the position directly opposite to the giving way groove 9, the position of the clamping groove 8 does not coincide with the rotation path of the limiting part 5. Therefore, the end of the limiting part 5 will conflict with the wall surface of the end of the supporting foot 7 outside the clamping groove 8, resulting in the inability to rotate the locking member 1, thereby causing the inability to lock the rotating end of the supporting foot; after setting the bevel angle 31, by continuing to rotate the locking member 1, the guiding effect of the bevel angle 31 can make the end of the supporting foot 7 that was originally unable to rotate and the limiting part 5 both produce a small rotation work, so that the position of the clamping groove 8 coincides with the rotation path of the limiting part 5, and then the limiting part 5 is rotated into the clamping groove 8 to limit the rotating end of the supporting foot 7. The setting of the bevel angle 31 can make the operation of the tripod lock structure more convenient when locking the tripod.

[0047] The utility model also discloses a lamp, such as Figures 9 to 12As shown in the combination, it includes a lamp housing 19, a plurality of supporting legs 7 that can be rotated to the bottom of the lamp housing 19 to form a tripod 20, and the above-mentioned lamp tripod lock structure, the connecting seat 2 is arranged at the bottom end of the lamp housing 19, and the side wall of the lamp housing 19 is provided with a plurality of grooves 21 for accommodating the supporting legs 7, and the end of the supporting leg 7 away from the side connected to the axis of the connecting seat 2 is provided with a foot pad 22, one end of the foot pad 22 is provided with at least one finger position 23 formed in the form of a groove, and the spatial contour inside the finger position 23 is the same as the contour of the fingertip, and the other end of the foot pad 22 is a connecting end 24 that fits in the supporting leg 7.

[0048] The above-mentioned lamp has a tripod lock structure composed of a plurality of supporting legs 7. After the supporting legs 7 are unfolded to the outside of the lamp with the ends of the supporting legs 7 in the matching grooves 6 as the rotation center to form the tripod 20, the supporting legs 7 can be locked by the tripod lock structure, thereby maintaining the stability of the supporting legs 7 that form the tripod 20 after being unfolded, so that the tripod 20 supports the lamp more stably; and the foot pads 22 arranged on the supporting legs 7 can not only prevent the ends of the supporting legs 7 close to the ground from being worn, but also can form a force with the foot pads 22 when the user uses the fingertips to touch the ends of the foot pads 22 to pull the supporting legs 7 to rotate during the process of turning out the supporting legs 7 or folding the supporting legs 7, through the finger positions 23 arranged at the ends of the foot pads 22. The point makes it easier for the user to use the fingertips to pull the support foot 7 to rotate, so that the support foot 7 can be quickly rotated and unfolded to form the tripod 20, and quickly folded to the outside of the lamp housing 19 to form a whole lamp; after the lamp equipped with the tripod lock structure is used in conjunction with the foot pad 22, the stability of the tripod 20 after unfolding is further enhanced, reducing the risk of damage to the tripod 20 itself and the lamp due to insufficient stability of the tripod 20, and can achieve the effect of the user's fingertips pulling the support foot 7 on the foot pad 22 to quickly rotate at the finger position 23, and cooperate with the locking and unlocking of the support foot 7 by the tripod lock structure to achieve the operation of quickly unfolding and locking the tripod 20 and quickly folding the tripod 20.

[0049] In addition, the projections of the wall surfaces of the foot pad 22 outside the two sides of the finger position 23 in the axial direction of the foot pad 22 are all arc lines.

[0050] like Fig.12 As shown, the wall contours of the foot pad 22 on both sides of the finger position 23 are similar to the contours on both sides of the fingertips, so that the shape of the space enclosed in the finger position 23 is similar to the outer contour of the fingertips. When the user's fingertips are in contact with the finger position 23 or near the end of the finger position 23, it is easier for the user's fingers to exert force, making it more convenient for the user to pull the supporting foot 7 to rotate.

[0051] As a further preference of the above embodiment, Fig.13 and Fig.14As shown in the figure, at least two through holes 25 are circumferentially provided on the wall surface of the foot pad 22 located at the connecting end 24, and a hook-shaped fastener 26 which is integrally formed with the wall surface of the foot pad 22 is provided in the through hole 25. At least two snap-in holes 27 are circumferentially provided on the end wall surface of the supporting foot 7 away from the axial connection side of the connecting seat 2, and the foot pad 22 is connected to the supporting foot 7 by snapping the fastener 26 with the snap-in hole 27.

[0052] When installing the foot pad 22, the connecting end 24 is inserted into the end of the supporting foot 7 along the direction corresponding to the fastener 26 and the snap-in hole 27. During the process of installing the connecting end 24 into the supporting foot 7, the hook-shaped portion on the fastener 26 enters the snap-in hole 27 and snaps into the edge of the snap-in hole 27, thereby fixing the foot pad 22 to the end of the supporting foot 7. When removing the foot pad 22, the end of the fastener 26 located in the matching hole 13 can be pressed to move the fastener 26 into the matching hole 13, thereby releasing the snap-in fit between the fastener 26 and the supporting connecting end 24, so that the foot pad 22 can be removed from the end of the supporting foot 7. The foot pad 22 is simple and quick to install and remove.

[0053] As a further preference of the above embodiment, Fig.14 As shown, the two side walls of the supporting foot 7 are recessed toward the center of the supporting foot 7 to form a convex surface 28, and the two side walls of the connecting end 24 are recessed toward the center of the connecting end 24 to form a concave surface 29 extending along the length direction of the connecting end 24; when the connecting end 24 is connected to the supporting foot 7, the convex surface 28 fits in the concave surface 29.

[0054] Among them, through the cooperation between the convex surface 28 and the concave surface 29, the connecting part 4 installed in the supporting foot 7 is limited by the wall surface of the supporting foot 7, so that the connecting part 4 cannot rotate in the end of the supporting foot 7, thereby ensuring that the connection stability between the foot pad 22 and the supporting foot 7 is higher when the foot pad 22 is removed without human operation.

[0055] As a further preference of the above embodiment, Fig. 9 and Fig.15 As shown in the figure, the end of the foot pad 22 away from the connecting end 24 is a supporting end 30, and the cross-sectional shape of the supporting end 30 is hexagonal.

[0056] Among them, since the middle part of the support end 30 is the large diameter end of the foot pad 22, when the support leg 7 is in the folded state, the foot pad 22 can be fixed in the groove body 21 through the interference fit between the middle part of the support end 30 and the groove body 21, so that the position of the support leg 7 in the folded state in the groove body 21 is maintained, preventing the support leg 7 from rotating from the groove body 21 and flipping out of the entire lamp under unintended conditions, thereby reducing the probability of damage to the support leg 7; at the same time, after the support leg 7 is unfolded, the cross-sectional shape of the support end 30 is hexagonal Therefore, with the large diameter end of the foot pad 22 as the dividing line, the cross-sectional shape of the end of the foot pad 22 located outside the finger position 23 is trapezoidal, and contacts the ground at this position. Different from the general foot pad 22 on the supporting foot 7, which adopts the method of contacting the ground with the circumferential edge of the end, when the supporting foot 7 is unfolded, the foot pad 22 in the utility model will contact the ground with its surface parallel to the axial direction, which is equivalent to increasing the contact area with the ground, so that the supporting effect of the supporting foot 7 on the lamp is improved after the supporting foot 7 is unfolded, so that the lamp can be better balanced.

[0057] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
