Description

Technical Field

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

[0002] The damping structure is used to provide resistance to the movement of an object to achieve the purpose of slowing down the movement of the object. The existing damping structure can achieve rapid extension and slow retraction of the telescopic rod through the cooperation of the inner inclined surface of the collar and the outer inclined surface of the clamping member. Specifically: during the extension of the rod, the inclined surface does not work, and the friction resistance between the rod and the clamping member is relatively small, which is convenient for rapid extension. During the retraction of the rod, the inclined surface plays a role, amplifying the friction resistance of the clamping member to the rod (greater than the friction resistance when extending), which can slow down the descent speed of the rod.

[0003] However, the collar itself is also a part with an adjustable inner diameter, and its inner diameter can be adjusted and determined by the screws and nuts outside the collar and the quick-release handle. When the inner diameter of the collar is adjusted too large (or too small), the inclined position of the clamping part will be too low (or too high), affecting the use of the quick-release handle.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the utility model discloses a damping structure 1, comprising a clamping ring 11, an outer ring 12 and an inner ring 13, specifically:

[0037] The clamping ring 11 is used to be sleeved on the outside of the telescopic rod 3 and hold the telescopic rod 3. The clamping ring 11 includes a first ring segment 111 and a second ring segment 112 in its axial direction. The outer sleeve 12 is sleeved on the outside of the clamping ring 11, and the inner wall surface of the outer sleeve 12 fits with the outer wall surface of the first ring segment 111 of the clamping ring 11. There is an annular storage space 14 between the inner wall surface of the outer sleeve 12 and the outer wall surface of the second ring segment 112 of the clamping ring 11. The inner sleeve 13 is arranged in the annular storage space 14, and the inner wall surface of the inner sleeve 13 and the outer wall surface of the second ring segment 112 of the clamping ring 11 are in a bevel matching structure.

[0038] In some embodiments, the clamping ring 11 and the outer ring 12 are elastic bodies, such as deformable plastic or metal. The inner ring 13 is a rigid body, such as non-deformable plastic or metal. The deformable or non-deformable plastic and metal here are only examples and are not intended to limit the present application.

[0039] In some embodiments, Figure 3 As shown, there is a gap between the inner ring 13 and the outer ring 12, that is, the outer ring 12 is only in contact with the clamping ring 11, and not in contact with the inner ring 13. Moreover, the outer wall surface of the inner ring 13 and the inner wall surface of the outer ring 12 extend along the axial direction of the clamping ring 11, that is, the outer wall surface of the inner ring 13 and the inner wall surface of the outer ring 12 are both vertical planes.

[0040] In some embodiments, Figure 3 As shown, the inner diameter of the inner ring 13 gradually increases from the first ring segment 111 of the clamping ring 11 to the second ring segment 112, and the outer diameter of the second ring segment 112 of the clamping ring 11 gradually decreases from the first ring segment 111 to the second ring segment 112, that is, the inner wall surface of the inner ring 13 is provided with a first inclined surface, and the outer wall surface of the clamping ring 11 is provided with a second inclined surface, and the first inclined surface and the second inclined surface cooperate with each other.

[0041] In some embodiments, Figure 2 As shown, the outer ring 12 includes an annular adjustment portion 121 and an annular fixing portion 122 in its axial direction. The annular adjustment portion 121 is sleeved on the outside of the clamping ring 11, and the inner wall surface of the annular adjustment portion 121 fits with the outer wall surface of the first ring segment 111 of the clamping ring 11. An annular storage space 14 is provided between the inner wall surface of the annular adjustment portion 121 and the outer wall surface of the second ring segment 112 of the clamping ring 11. The annular fixing portion 122 is located at the end of the second ring segment 112 of the clamping ring 11. The telescopic rod 3 is accommodated in the main rod 2 and can extend out of one end of the main rod 2. The annular fixing portion 122 is used to be sleeved on the outside of the main rod 2 and hold the main rod 2, and the clamping ring 11 is used to be sleeved on the outside of the telescopic rod 3 and hold the telescopic rod 3. Specifically, when the telescopic rod 3 is retracted, the main rod 2 abuts against the inner ring 13 in its axial direction, that is, the top of the main rod 2 abuts against the bottom of the inner ring 13, which can prevent the inner ring 13 from being moved by the telescopic rod 3 and the clamping ring 11 and thus detached.

[0042] In some embodiments, Figure 3 As shown, at least one annular receiving groove 1111 is provided on the outer wall surface of the first ring segment 111 of the clamping ring 11, and the damping structure 1 also includes at least one elastic ring 15, which is sleeved in the annular receiving groove 1111 to provide a clamping force or a squeezing force to the telescopic rod 3 passing through the clamping ring 11. It can be understood that the at least one can be one, two, three or any number. In order to prevent the clamping force from being lost due to damage of one elastic ring 15, at least two annular receiving grooves 1111 are provided on the outer wall surface of the first ring segment 111 of the clamping ring 11, and the damping structure 1 also includes at least two elastic rings 15.

[0043] In some embodiments, Figure 2As shown, at least two limiting portions 1211 are provided on the inner wall surface of the outer sleeve 12, specifically, at least two limiting portions 1211 are provided on the inner wall surface of the annular adjustment portion 121, the limiting portion 1211 is located at the end of the first ring segment 111 of the clamping ring 11, and is used to abut against the clamping ring 11, and at least two limiting portions 1211 are arranged at intervals along the circumference of the outer sleeve 12, so as to ensure that the outer sleeve 12 balances the circumferential force of the clamping ring 11. Specifically, when the telescopic rod 3 is extended, the limiting portion 1211 can prevent the clamping ring 11 from being driven by the telescopic rod 3 to move and thus detach.

[0044] In some embodiments, such as Figure 1 and Figure 2 As shown, the side wall of the outer collar 12 has a first opening 123, the side wall of the clamping ring 11 has a second opening 113, and the damping structure 1 further includes a locking assembly 16 connected to the first opening 123 and capable of shrinking the first opening 123. Specifically, when the outer collar 12 is installed, the first opening 123 can be opened to facilitate installation, and the locking assembly 16 shrinks the first opening 123, so that the outer collar 12 can squeeze the clamping ring 11, thereby causing the clamping ring 11 to generate a clamping force on the telescopic rod 3. After the locking assembly 16 is unlocked, the first opening 123 of the outer collar 12 expands automatically under the action of its own restoring force, thereby being able to adjust the clamping force of the clamping ring 11 on the telescopic rod 3.

[0045] In addition, the first opening 123 of the outer collar 12 and the second opening 113 of the clamping ring 11 can be rotationally misaligned or correspond to each other. In the corresponding case, when the locking assembly 16 adjusts the first opening 123, it can maximize the transmission of the contraction force of the outer collar 12 to the clamping ring 11, that is, the contraction strokes of the outer collar 12 and the clamping ring 11 can be kept consistent, thereby avoiding the loss of mechanical energy. For example, when the first opening 123 is very small, if the second opening 113 does not correspond to the first opening 123, the contraction stroke of the outer collar 12 is smaller than the contraction stroke of the first opening 123.

[0046] In addition, a first extension portion 1212 and a second extension portion 1213 extend outward from the outer ring 12 on opposite sides of the first opening 123 , specifically, a first extension portion 1212 and a second extension portion 1213 extend outward from the annular adjustment portion 121 , and the locking assembly 16 connects the first extension portion 1212 and the second extension portion 1213 to shrink the first opening 123 .

[0047] The locking assembly 16 includes a connecting rod 161 and a locking member 162. The connecting rod 161 passes through the first extension portion 1212 and the second extension portion 1213 in sequence and can move on the first extension portion 1212 and the second extension portion 1213. One end of the connecting rod 161 is provided with a stopper 1611 that is stopped on the first extension portion 1212. The locking member 162 is rotatably connected to an end of the connecting rod 161 opposite to the stopper 1611, and the locking member 162 abuts against the second extension portion 1213. The stopper 1611 and the locking member 162 enable the connecting rod 161 to connect the first opening 123. A curved surface (not shown in the figure) is provided on one side of the locking member 162 that abuts against the second extension portion 1213. The curved surface of the locking member 162 can loosen or shrink the first opening 123 when rotating on the second extension portion 1213. Specifically, the curved surface includes the closest point and the farthest point from the connection between the locking member 162 and the connecting rod 161, similar to a cam structure, when the farthest point of the curved surface abuts against the second extension portion 1213, the first opening 123 is contracted, and when the closest point of the curved surface abuts against the second extension portion 1213, the first opening 123 is released. For example, the locking portion 1611 can be a nut, and a partial area of ​​one end of the connecting rod 161 is provided with a thread that matches the nut, and the nut and thread here are only examples and are not intended to limit the present application.

[0048] Specifically, when the telescopic rod 3 needs to be stored, the first opening 123 is loosened by the locking assembly 16. At this time, the friction between the clamping ring 11 and the telescopic rod 3 allows the telescopic rod 3 to slowly descend under its own gravity and / or other loads (such as the lamp head 4 described below). After the telescopic rod 3 is retracted, the first opening 123 is contracted by the locking assembly 16 to lock the telescopic rod 3, thereby achieving locking of the telescopic rod 3.

[0049] When the telescopic rod 3 needs to be extended, the first opening 123 is first released by the locking assembly 16 , and then the first opening 123 is retracted by the locking assembly 16 after the telescopic rod 3 is pulled out, thereby also achieving locking of the telescopic rod 3 .

[0050] When in use, the clamping ring 11 is used to be sleeved on the outside of the telescopic rod 3 and hold the telescopic rod 3. When the telescopic rod 3 is extended or retracted, it moves relative to the clamping ring 11 to generate friction. The second opening 113 of the clamping ring 11 enables the clamping ring 11 to have the ability to contract and expand in the radial direction. The outer ring 12 is sleeved on the outside of the clamping ring 11 to limit the position of the clamping ring 11 in the radial direction. The inner wall surface of the inner ring 13 is provided with a first inclined surface, and the outer wall surface of the clamping ring 11 is provided with a second inclined surface. The first inclined surface and the second inclined surface cooperate with each other. Since the inner ring 13 is an independent part, it is more convenient to adjust the inner diameter of the outer ring 12 during the production and assembly process. There is no need to consider the influence of the inner diameter of the outer ring 12 on the inclined surface, nor is there any need to consider the upper and lower height issues of the clamping ring 11.

[0051] When the telescopic rod 3 is extended, friction is generated between the telescopic rod 3 and the clamping ring 11, thereby having a tendency to drive the clamping ring 11 to move from the second ring segment 112 to the first ring segment 111, that is, Figure 3 In the direction A shown in the figure, the gap between the clamping ring 11 and the inner ring 13 tends to increase, the friction between the clamping ring 11 and the inner ring 13 decreases, and the telescopic rod 3 can be extended quickly. When the telescopic rod 3 retracts, the telescopic rod 3 and the clamping ring 11 generate friction, thereby having a tendency to drive the clamping ring 11 to move from its first ring segment 111 to the second ring segment 112, that is, Figure 3 In the B direction shown in the figure, the gap between the clamping ring 11 and the inner ring 13 tends to decrease, and the friction between the clamping ring 11 and the inner ring 13 increases, thereby increasing the friction between the clamping ring 11 and the telescopic rod 3, and the telescopic rod 3 retracts smoothly, thereby achieving a better damping effect.

[0052] like Figure 4 As shown, an embodiment of the utility model discloses a telescopic lamp, comprising a main rod 2, a telescopic rod 3, a lamp head 4 and the damping structure 1 described in the above embodiment, wherein the damping structure 1 is not described in detail here, specifically:

[0053] The telescopic rod 3 is accommodated in the main rod 2 and can extend out of one end of the main rod 2. The lamp holder 4 is arranged on the end of the telescopic rod 3 away from the main rod 2. The outer ring 12 is fixed to one end of the main rod 2 and is sleeved on the outside of the telescopic rod 3. The inner wall surface of the clamping ring 11 abuts against the outer wall surface of the telescopic rod 3 to provide friction for the telescopic rod 3 when it is extended or retracted.

[0054] By implementing the utility model, the following beneficial effects are achieved:

[0055] The damping structure provided by the utility model provides an inner ring as an independent part between the clamping ring and the outer ring, thereby making it more convenient to adjust the inner diameter of the outer ring during the production and assembly process, without having to consider the influence of the inner diameter of the outer ring on the inclined surface, and without having to consider the upper and lower height issues of the clamping ring.

[0056] Moreover, during the extension and retraction process of the telescopic rod, the force in the two moving directions of the telescopic rod can be adjusted, so that the telescopic rod can be extended quickly when extended and retracted smoothly when retracted, which takes into account both the damping design of the lamp and the increase in the opening rate during use, thereby improving the user experience.

[0057] It can be understood that the above embodiments only express some implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the utility model; it should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, the above embodiments or technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model, that is, the embodiments described in "some embodiments" can be freely combined with any of the above and below embodiments; therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should fall within the scope of the claims of the utility model.
