Description

Technical Field

[0001] The utility model relates to the field of lighting devices, in particular to a base connection structure. Background Art

[0002] Handheld lighting devices are generally rarely placed in an overall vertical form. Due to the small radial size of their bottom or the insufficient flatness of the bottom surface, most of them are placed on the surface of an object in a lying manner or with the light source end of the lighting device as the support for the balance of the lighting device.

[0003] If the lighting device needs to be placed with the light source end facing upward, it is necessary to use some structures that are arranged on the base of the lighting device and form a detachable connection with the base of the lighting device to ensure the stability of the lighting device when it is placed with the light source end facing upward. In order to solve this problem, some lighting devices are designed to have a bottom end that is larger than the overall radial dimension of the base to ensure the stability of the lighting device when it is placed with the light source end facing upward. However, this design will affect the user's feeling when holding the lighting device. Utility Model Content

[0015] Furthermore, the boss is connected to convex strip one and convex strip two at both ends of the base in the radial direction, respectively; convex strip one is located on the base surface close to the center of the base, and convex strip two is distributed along the outer edge of the bottom surface of the base; one edge of the convex strip and the edge of the convex strip two are provided with a beveled surface three, and the beveled surface one is distributed in a semi-enclosed form on the end surface of each step of the step.

DETAILED DESCRIPTION

[0035] The utility model discloses a base connection structure, such as Figures 1 to 6As shown in the figure, the connection structure is connected to the bottom end of the lighting device, including:

[0036] The quick release plate 1 has a ring edge 101 on its outer edge, and the ring edge 101 surrounds a cavity 3;

[0037] A base 2 is arranged at the bottom end of the lighting device and is rotatably fitted in the cavity 3;

[0038] A limit block 102 is circumferentially arranged on the inner wall of the ring edge 101;

[0039] The limiting groove 201 is arranged along the circumferential direction of the outer wall of the base 2;

[0040] The step 103 is located on the wall surface of the quick release plate 1 in the cavity 3 and is arranged along the circumferential direction of the quick release plate 1;

[0041] A boss 202 is provided on the outer surface of the base 2;

[0042] Among them, the boss 202 moves to the top of the step 103 under the rotation of the base 2 to lift the base 2, one end of the limit groove 201 is an opening 203, and the opening 203 is connected to the bottom surface of the base 2. The limit block 102 enters the limit groove 201 from the opening 203 under the rotation of the base 2 and is tangent to the wall of the limit groove 201 away from the opening 203.

[0043] It should be noted that the lighting device is installed into the quick-release plate 1 along the cavity matching direction of the base 2. At this time, the top surface of the limit block 102 is against the outer edge of the bottom of the base 2. The opening 203 is moved toward the limit block 102 by rotating the lighting device. This process requires applying a thrust to the lighting device in the direction of the quick-release plate 1 to cooperate with the rotation work, so that the limit block 102 enters the opening 203 when the lighting device rotates; the lighting device is continued to be rotated so that the limit block 102 reaches the end of the opening 203 away from the bottom surface of the base 2. When the quick-release plate 1 can no longer move in the axial direction of the base 2, it means that the bottom surface of the base 2 close to the boss 202 side is against the top surface of the step 103. After continuing to rotate the lighting device, the limit block 102 will move to the limit groove 201 away from the opening 203. The base 2 moves inwardly, and the step 103 is used to lift the boss 202, so that the height position of the base 2 in the cavity is raised, so that the distance between the wall of the limiting groove 201 and the limiting block 102 is gradually reduced, until the limiting block 102 is tangent to the wall of the limiting groove 201 away from the opening 203, so that the base 2 and the quick-release plate 1 are tightly connected. The quick-release plate 1 forms a pad structure outside the base 2 of the lighting device, so that the lighting device can be stably placed on the surface of other objects, and it also protects the base 2 of the lighting device. In addition, the operation of connecting the base 2 to the quick-release plate 1 is simple and quick, and it can be achieved by only installing the lighting device into the quick-release plate 1 and then rotating it; even when the lighting device is hand-held, the quick-release plate 1 is still firmly connected to the outside of the base 2 and will not be loosened from the base 2.

[0044] As one of the embodiments of the present utility model, Figures 3 to 6 As shown in the figure, the ends of each step of the step 103 are transitioned through the beveled surface 104, the two ends of the boss 202 and the bottom surface of the base 2 are transitioned through the beveled surface 204, and the boss 202 is moved to the top of the boss 202 through the beveling effect between the beveled surface 204 and the beveled surface 104.

[0045] Among them, the boss 202 moves to the step 103 in the direction relative to the bevel surface 204 and the bevel surface 1 104, and utilizes the bevel effect of the bevel surface 1 104 and the bevel surface 2 204 to realize the lifting of the height of the base 2. By utilizing the bevel cooperation to form a structure for adjusting the height of the base 2, the lifting of the base 2 is realized in a relatively simple way.

[0046] Preferably, Figure 4As shown, the boss 202 is connected to the convex strip 1 105 and the convex strip 2 206 at both ends of the radial direction of the base 2, respectively. The convex strip 105 is located on the surface of the base 2 close to the center of the base 2, and the convex strip 206 is distributed along the outer edge of the bottom surface of the base 2. The edges of the convex strip 105 and the edges of the convex strip 206 are both provided with a beveled surface 3 205 connected to the beveled surface 104. The beveled surface 104 is distributed in a semi-enclosed form on the end surface of each step of the step 103.

[0047] Among them, the step 103 reaching the outer position of the boss 202 can be limited by the convex strip 1 105 and the convex strip 206, and the position of the step 103 is maintained near the space surrounded by the boss 202, the convex strip 105 and the convex strip 206, which is beneficial for the step 103 and the boss 202 to be beveled as much as possible through the chamfered surface 104 and the chamfered surface 204 at the relative position of the two when the quick release plate 1 rotates to raise the height of the base 2; the chamfered surface 104 is distributed in a semi-enclosed form, which can make the range of the chamfered surface 104 of the step 103 larger, so that the step 103 can be beveled with the chamfered surface 3 205 at a position other than its end surface, so as to facilitate the top surface of the step 103 to reach the bottom surface of the boss 202 to abut against it.

[0048] Preferably, Figure 3 , Figure 5 , Figure 6 and Fig. 9 As shown in the figure, the base 2 outside the two sides of the step 103 is provided with through grooves 106.

[0049] Among them, due to the setting of the through groove 106, there is a gap between the two sides of the step 103 and the base 2, so that when the boss 202 and the step 103 are against each other, the step 103 can have a certain elastic deformation ability. When the boss 202 and the step 103 are against each other, a damping force is formed for the against position of the two, thereby maintaining the fixation of the boss 202 and the step 103.

[0050] As one of the embodiments of the present utility model, Figure 4 and Figure 8 As shown in the figure, the wall surface of the limiting groove 201 close to the opening 203 is provided with a bevel surface 107, and the bevel effect between the limiting block 102 and the bevel surface 107 guides the limiting block 102 to move into the limiting groove 201 away from the opening 203.

[0051] Among them, after the limit block 102 enters the opening 203, the distance between the limit groove 201 and the wall of the limit groove 201 at the opening 203 will become smaller and smaller as the height of the base 2 rises. If the width of the opening 203 is not enough, the limit block 102 will be against the wall of the limit groove 201 at the opening 203, resulting in the limit block 102 being unable to move to the limit groove 201 away from the opening 203; therefore, the beveled surface 107 can not only solve this problem, but also better guide the limit block 102 to the limit groove 201 close to the opening 203, so that the operation of connecting the base 2 to the quick release plate 1 is smoother.

[0052] As one of the embodiments of the present utility model, Figure 7 As shown, both sides of the top of the limit block 102 are provided with beveled surfaces 5 207 , and the wall surfaces on both sides of the end of the opening portion 203 close to the base 2 are provided with beveled surfaces 6 208 that are beveled and matched with the beveled surfaces 4 107 .

[0053] In this embodiment, when the lighting device is rotated, when the limit block 102 moves to a position where the opening 203 is close to the bottom surface of the base 2, the limit block 102 can use the beveling effect between the beveled surface 5 207 and the beveled surface 6 208 to guide it into the opening 203, thereby facilitating the limit block 102 to enter the limit groove 201 when the quick release plate 1 is rotated. Even if the base 2 that has just been installed in the quick release plate 1 has a situation where the top surface of the limit block 102 and the outer edge of the bottom of the base 2 are abutted during rotation, as long as the beveling effect of the beveled surface 5 207 and the beveled surface 6 208 occurs, no matter whether the quick release plate 1 is rotated clockwise or counterclockwise, the operation of the limit block 102 entering the limit groove 201 becomes simpler and smoother.

[0054] As one of the embodiments of the present utility model, Figure 2 and Figure 3 As shown in the figure, the ring edge 101 is a non-closed ring structure, and the non-closed part of the ring edge 101 forms a clearance opening 108.

[0055] In this embodiment, the non-closed portion of the clearance opening 108 on the ring edge 101 forms a space for components protruding from the main body of the lighting device to avoid during the rotation of the lighting device, so as to avoid the situation where the components protruding from the main body of the lighting device collide with the ring edge 101 when the lighting device is rotated and cannot rotate.

[0056] As one of the embodiments of the present utility model, Figure 2 and Figure 3 As shown in the figure, the inner wall of the ring edge 101 is provided with a plurality of evacuation grooves 109 for avoiding position.

[0057] Among them, since some lighting devices have components protruding from the surface of the main body of the lighting device, there may be interference with the ring edge 101 when the lighting device is rotated, affecting the user's rotation operation of the lighting device; and the setting of the clearance groove 109 can provide a space for avoidance, so that the components protruding from the surface of the main body of the lighting device will not affect the rotation of the lighting device.

[0058] As one of the embodiments of the present utility model, Fig. 9 As shown, a plurality of grooves 110 are circumferentially arranged on the bottom surface of the quick release plate 1 .

[0059] In this embodiment, a groove 110 is provided at the bottom of the quick release plate 1 for sticking double-sided tape, so as to achieve the function of fixing the quick release plate 1 on the working surface of other objects. After the position of the quick release plate 1 is fixed, the operation of rotating the lighting device to be installed or removed will become more convenient.

[0060] As one of the embodiments of the present utility model, Figure 3 , Figure 5 , Figure 6 and Fig. 9 As shown in the figure, the bottom end of the base 2 is provided with a through hole 209 facing the limiting block 102 .

[0061] In this embodiment, the position of the limit block 102 can be determined through the through hole 209. When the lighting device is rotated to fit the base 2 into the quick-release plate 1, the position of the limit block 102 is determined through the through hole 209, thereby quickly determining the rotation direction of the lighting device and accurately and quickly installing the base 2 into the quick-release plate 1.

[0062] 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.
