Description

Technical Field

[0001] The utility model relates to the technical field of lamp lighting, in particular to an angle adjustment structure and a lamp. Background Art

[0002] At present, the lamps with angle adjustment function on the market generally use screws to fix the angle adjustment structure (such as the sleeve of the lamp) on the main body of the lamp. When the angle of the adjustment structure needs to be adjusted, the screws need to be loosened with a tool, and then the angle of the angle adjustment structure needs to be adjusted. After adjusting to the appropriate position, the screws need to be tightened again with a tool, so that the angle adjustment structure is fixed on the main body of the lamp at a suitable angle. This angle adjustment method has the following disadvantages: 1. The angle needs to be adjusted with a tool, and the steps are relatively cumbersome; 2. The lamps are generally located at high altitudes, and there is a risk of tools falling when adjusting the angle at high altitudes. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, one of the purposes of the present invention is to provide an angle adjustment structure. The second purpose of the present invention is to provide a lamp that can solve the problems of complicated steps and the risk of tools falling caused by using tools when adjusting the angle of the lamp.

[0004] One of the purposes of the utility model is achieved by the following technical solution:

[0005] An angle adjustment structure, comprising:

[0006] A connecting shaft, a first ratchet mechanism, a second ratchet mechanism, a first locking mechanism, and a second locking mechanism;

[0007] The first ratchet mechanism and the second ratchet mechanism are respectively arranged at two ends of the connecting shaft; the first locking mechanism can switch the first ratchet mechanism between a working state and a non-working state, and when the first ratchet mechanism is in the working state, the connecting shaft is only allowed to rotate around a first direction; the second locking mechanism can switch the second ratchet mechanism between a working state and a non-working state, and when the second ratchet mechanism is in the working state, the connecting shaft is only allowed to rotate around a second direction;

[0008] The first direction is opposite to the second direction, and both the first direction and the second direction are axial directions around the connecting axis.

[0009] Furthermore, the first ratchet mechanism includes a first ratchet and a first pawl. When the first ratchet mechanism is in a working state, the first ratchet is combined with the first pawl. When the first ratchet is in a non-working state, the first ratchet is separated from the first pawl.

[0010] Furthermore, the first locking mechanism includes a first pull rod, which is disposed on the first pawl; pulling the first pull rod in a direction away from the first ratchet can drive the first pawl to separate from the first ratchet.

[0011] Furthermore, the first pawl is arranged above the first ratchet, and the first pawl can be reset to be combined with the first ratchet under the action of gravity.

[0012] Furthermore, a first spring is sleeved on the first pull rod, and the first spring is fixedly arranged. The first pawl can be reset to be combined with the first ratchet wheel under the elastic force of the first spring.

[0013] Furthermore, the first pull rod is threadedly connected to the first pawl.

[0014] Furthermore, the second ratchet mechanism includes a second ratchet and a second pawl. When the second ratchet mechanism is in a working state, the second ratchet is combined with the second pawl, and when the second ratchet is in a non-working state, the second ratchet is separated from the second pawl. The ratchet teeth of the second ratchet are in opposite directions to the ratchet teeth of the first ratchet.

[0015] Furthermore, the second locking mechanism includes a second pull rod, which is disposed on the second pawl; pulling the second pull rod in a direction away from the second ratchet can drive the second pawl to separate from the second ratchet.

[0016] Furthermore, the second pawl is arranged above the second ratchet, the second pull rod is sleeved with a second spring, the second spring is fixedly arranged, and the second pawl can be reset to be combined with the second ratchet under the elastic force of the second spring and the gravity of the second pawl.

[0017] The second purpose of the utility model is achieved by the following technical solution:

[0018] A lamp comprises the above-mentioned angle adjustment structure, a sleeve and a lamp body, wherein the sleeve is fixedly connected to a connecting shaft of the angle adjustment structure, and the lamp body is rotatably connected to the connecting shaft of the angle adjustment structure.

[0019] Compared with the prior art, the beneficial effect of the utility model is that the rotation angle adjustment of the connecting shaft can be achieved by adjusting the working state of the first ratchet mechanism and the second ratchet mechanism; specifically, when the connecting shaft is to be rotated around the first direction, the second ratchet mechanism can be switched to a non-working state through the second locking mechanism, and the connecting shaft can be rotated around the first direction; when the connecting shaft is to be rotated around the second direction, the first ratchet mechanism can be switched to a non-working state through the first locking mechanism, and the connecting shaft can be rotated around the second direction. Therefore, when the angle of the lamp body needs to be adjusted, it can be adjusted in the same way as adjusting the rotation angle of the connecting shaft, and the entire adjustment process does not require the use of tools, the operation is simple, and there is no need to worry about the risk of tools falling.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0028] Embodiment 1

[0029] like Figure 1-2 As shown, the angle adjustment structure disclosed in the embodiment of the utility model is shown, which includes a connecting shaft 1, a first ratchet mechanism 2, a second ratchet mechanism 3, a first locking mechanism 4 and a second locking mechanism 5. The first ratchet mechanism 2 and the second ratchet mechanism 3 are respectively arranged at the two ends of the connecting shaft 1; the first locking mechanism 4 can switch the first ratchet mechanism 2 between a working state and a non-working state, and when the first ratchet mechanism 2 is in a working state, the connecting shaft 1 can only be allowed to rotate around a first direction; the second locking mechanism 5 can switch the second ratchet mechanism 3 between a working state and a non-working state, and when the second ratchet mechanism 3 is in a working state, the connecting shaft 1 can only be allowed to rotate around a second direction. Among them, the first direction is opposite to the second direction, and the first direction and the second direction are both directions around the axial direction of the connecting shaft 1.

[0030] Specifically, refer to Figure 2 The first ratchet mechanism 2 includes a first ratchet 21 and a first pawl 22. When the first ratchet mechanism 2 is in a working state, the first ratchet 21 is combined with the first pawl 22. When the first ratchet mechanism 2 is in a non-working state, the first ratchet 21 is separated from the first pawl 22. The second ratchet mechanism 3 includes a second ratchet 31 and a second pawl 32. When the second ratchet mechanism 3 is in a working state, the second ratchet 31 is combined with the second pawl 32. When the second ratchet mechanism 3 is in a non-working state, the second ratchet 31 is separated from the second pawl 32. The ratchet teeth of the second ratchet 31 are opposite to those of the first ratchet 21.

[0031] In the above-mentioned setting, when the first ratchet mechanism 2 is in working condition, the connecting shaft 1 can only rotate around the first direction (that is, it can only rotate unidirectionally along the first direction), and when the second ratchet mechanism 3 is in working condition, the connecting shaft 1 can only rotate around the second direction (that is, it can only rotate unidirectionally along the second direction), and the first direction is opposite to the second direction, so when the first ratchet mechanism 2 and the second ratchet mechanism 3 are both in working condition, the connecting shaft 1 is actually restricted from rotating at will.

[0032] When the connecting shaft 1 is to be rotated around the first direction, since the first ratchet mechanism 2 can allow the connecting shaft 1 to rotate around the first direction when in the working state, there is no need to operate the first ratchet mechanism 2, that is, there is no need to change the working state of the first ratchet mechanism 2 through the first locking mechanism 4; but the second ratchet mechanism 3 can only allow the connecting shaft 1 to rotate around the second direction when in the working state. In other words, the connecting shaft 1 cannot rotate around the first direction at this time. Therefore, it is necessary to switch the second ratchet mechanism 3 to the non-working state through the second locking mechanism 5. At this time, the unidirectional rotation of the connecting shaft 1 along the second direction is released, and the connecting shaft 1 can rotate around the first direction. When the connecting shaft 1 rotates around the first direction to the angle that needs to be adjusted, the second ratchet 31 can be switched to the working state again through the second locking mechanism 5, and the connecting shaft 1 will be restricted from rotating at will again.

[0033] Similarly, when you want to rotate the connecting shaft 1 in the second direction, you only need to switch the first ratchet mechanism 2 to the non-working state through the first locking mechanism 4, so that the connecting shaft 1 can rotate in the second direction. When the connecting shaft 1 rotates in the second direction to the angle that needs to be adjusted, the first ratchet 21 is switched to the working state through the second locking mechanism 5, so that the connecting shaft 1 cannot rotate at will.

[0034] In actual use, refer to Figure 3-4 , the lamp body 7 is installed on the lamp pole through the sleeve 6, the sleeve 6 is fixedly connected to the connecting shaft 1 of the angle adjustment structure, and the lamp body 7 is rotatably connected to the connecting shaft 1 of the angle adjustment structure. When the angle of the lamp body 7 relative to the lamp pole needs to be adjusted, it is actually necessary to rotate the lamp body 7 around the connecting shaft 1 by a certain angle. At this time, the connecting shaft 1 is regarded as a fixed part and the lamp body 7 is regarded as a rotating part. However, according to the principle of relativity of motion, the connecting shaft 1 can be regarded as a rotating part and the lamp body 7 can be regarded as a fixed part, and the rotation direction of the connecting shaft 1 and the rotation direction of the lamp body 7 need to be regarded as opposite directions. For example, when the lamp body 7 needs to rotate in the first direction, it can be regarded as that the connecting shaft 1 needs to rotate in the second direction; therefore, the angle of the lamp body 7 relative to the lamp pole can be adjusted according to the above-mentioned method of adjusting the angle of the connecting shaft 1. It can be seen from the above-mentioned method of adjusting the angle of the connecting shaft 1 that the entire adjustment process does not require the use of tools, and the adjustment is very convenient, so there is no need to worry about the risk of the tool falling. In addition, after adjusting the angle, the lamp body 7 can be maintained at the corresponding angle without rotating at will.

[0035] In this embodiment, the first locking mechanism 4 includes a first pull rod 41, which is disposed on the first pawl 22; pulling the first pull rod 41 in a direction away from the first ratchet 21 can drive the first pawl 22 to separate from the first ratchet 21. The first pull rod 41 can be provided to facilitate the user's operation, that is, the user can pinch the first pull rod 41 with fingers, and then pull it in a direction away from the first ratchet 21 to put the first ratchet mechanism 2 in a non-working state, and at this time the connecting shaft 1 can rotate around the second direction.

[0036] In this embodiment, the first pawl 22 is arranged above the first ratchet 21, and the first pawl 22 can be reset to be combined with the first ratchet 21 under the action of gravity. Such a setting can facilitate the operation of the user, that is, when the user wants to switch the first ratchet mechanism 2 to the working state, he only needs to remove the external force on the first pawl 22, and it can automatically switch to the working state under the action of gravity, which is very convenient.

[0037] In this embodiment, refer to Figure 2 as well as Figure 4 The first pull rod 41 is sleeved with a first spring 42, which is fixedly arranged, and the first pawl 22 can be reset to be combined with the first ratchet wheel 21 under the elastic force of the first spring 42. By setting the first spring 42, the reset effect of the first pawl 22 can be further ensured.

[0038] In this embodiment, the first pull rod 41 is threadedly connected to the first pawl 22. In this way, it is convenient to disassemble and assemble, thereby facilitating the inspection and replacement thereof.

[0039] In this embodiment, refer to Figure 2 The second locking mechanism 5 includes a second pull rod 51, which is arranged on the second pawl 32; pulling the second pull rod 51 in a direction away from the second ratchet 31 can drive the second pawl 32 to separate from the second ratchet 31. The second pawl 32 is arranged above the second ratchet 31, and a second spring 52 is sleeved on the second pull rod 51. The second spring 52 is fixedly arranged, and the second pawl 32 can be reset to be combined with the second ratchet 31 under the elastic force of the second spring 52 and the gravity of the second pawl 32. Similarly, such a setting can facilitate the operation of the user.

[0040] Embodiment 2

[0041] Reference Figure 3-4As shown, a lamp disclosed in the second embodiment is shown, which includes the angle adjustment structure of the first embodiment, a sleeve 6 and a lamp body 7. The sleeve 6 is fixedly connected to the connecting shaft 1 of the angle adjustment structure, and the lamp body 7 is rotatably connected to the connecting shaft 1 of the angle adjustment structure. Specifically, a first receiving groove and a second receiving groove are provided in the lamp body 7. The first receiving groove is used to accommodate the first spring 42, and the second receiving groove is used to accommodate the second spring 52. The sleeve 6 is used to connect the lamp body 7 to the lamp pole. The first ratchet 21 and the second ratchet 31 are respectively arranged at the two ends of the connecting shaft 1 so as not to rotate relative to each other, and the first pawl 22 and the second pawl 32 are respectively arranged on the lamp body 7.

[0042] When it is necessary to adjust the angle of the lamp body 7 relative to the lamp pole, it is actually necessary to rotate the lamp body 7 around the connecting shaft 1 at a certain angle. At this time, the connecting shaft 1 is regarded as a fixed part and the lamp body 7 is regarded as a rotating part. However, according to the principle of relativity of motion, the connecting shaft 1 can be regarded as a rotating part and the lamp body 7 can be regarded as a fixed part. In addition, the rotation direction of the connecting shaft 1 and the rotation direction of the lamp body 7 need to be regarded as opposite. For example, when the lamp body 7 needs to rotate in a first direction, it can be regarded as the need for the connecting shaft 1 to rotate in a second direction. Therefore, the angle of the lamp body 7 relative to the lamp pole can be adjusted in accordance with the above-mentioned method of adjusting the angle of the connecting shaft 1. As can be seen from the method of adjusting the angle of the connecting shaft 1 in Example 1, the entire adjustment process does not require the use of tools, and the adjustment is very convenient, so there is no need to worry about the risk of the tool falling. In addition, after adjusting the angle, the lamp body 7 can be maintained at the corresponding angle without rotating at will.

[0043] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
