Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a lamp tube clamping mechanism which is easy to operate. Background Art

[0002] In the field of photography, lamps are usually needed for lighting or fill-in lighting, so a clamping mechanism is usually needed to fix the lamps.

[0003] In the related art, the clamping mechanism for clamping the lamp tube usually includes two clamping members rotatably connected to each other. After the two clamping members clamp the lamp tube, they need to be locked together with the help of a screw to prevent the clamping mechanism from opening. However, it is cumbersome to operate when locking the two clamping members with a screw. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a lamp tube clamping mechanism that is convenient to use and easy to operate.

[0005] According to some embodiments of the utility model, the easy-to-operate lamp tube clamping mechanism includes: a first clamping member; a second clamping member, wherein the first end of the second clamping member is rotatably connected to the first end of the first clamping member; a locking assembly, wherein the locking assembly includes a locking member and an elastic reset member, wherein the locking member is rotatably arranged at the second end of the first clamping member, and the elastic reset member is arranged on the first clamping member and connected to the locking member;

[0006] Wherein, the second end of the second clamping member is provided with a locking groove, and the second end of the second clamping member is provided with a guiding portion. When the second end of the second clamping member moves toward the second end of the first clamping member, the guiding portion can force the locking member to rotate in the unlocking direction so that the locking member passes through the notch of the locking groove and enters the locking groove through the notch of the locking groove. The elastic reset member can drive the locking member to rotate in the locking direction after the locking member enters the locking groove to buckle the second clamping member.

[0007] The easy-to-operate lamp tube clamping mechanism according to the embodiment of the utility model has at least the following beneficial effects:

[0008] During use of the easy-to-operate lamp tube clamping mechanism of the utility model, when it is necessary to clamp the lamp tube, the lamp tube can be first placed in the first half groove of the first clamping member, and then the second clamping member is rotated to make the second end of the second clamping member gradually approach the second end of the first clamping member, so that the second clamping member and the first clamping member clamp the lamp tube together; when the second clamping member is rotated into place, the locking assembly buckles the first clamping member and the second clamping member together, thereby ensuring that the first clamping member and the second clamping member continue to apply clamping force to the object to prevent the object from falling off. In the process of rotating the second clamping member so that the second end of the second clamping member moves toward the second end of the first clamping member, the guide part will first press the lock member so that the lock member rotates in the unlocking direction so that the lock member passes through the notch of the lock slot. When the lock member passes through the notch of the lock slot, as the second end of the second clamping member continues to move toward the second end of the first clamping member, the lock member will enter the lock slot through the notch of the lock slot. After that, under the action of the elastic reset member, the lock member will rotate in the locking direction and extend into the interior of the lock slot, thereby buckling the second clamping member, thereby realizing the buckling of the second end of the first clamping member with the second end of the second clamping member. When the easy-to-operate lamp tube clamping mechanism of the utility model is used, if it is necessary to clamp an object between the first clamping member and the second clamping member, it is only necessary to place the object on the first clamping member and then rotate the second clamping member until the second clamping member is buckled by the lock member.

[0009] According to some embodiments of the utility model, a locking column is provided on the locking member, the locking column is arranged in parallel with the rotation center axis of the locking member and is spaced apart, and the locking groove extends in an arc shape;

[0010] When the second end of the second clamping member moves toward the second end of the first clamping member, the guide portion can force the locking member to rotate in the unlocking direction so that the locking column passes through the notch of the locking groove and enters the locking groove through the notch of the locking groove, and the elastic reset member can drive the locking member to rotate in the locking direction after the locking column enters the locking groove through the notch of the locking groove so that the locking column buckles the second clamping member.

[0011] According to some embodiments of the present invention, a positioning groove is provided at the second end of the first clamping member, and the guide portion extends into the positioning groove when the second end of the second clamping member is butted against the second end of the first clamping member.

[0014] Wherein, the second end of the first clamping member is further provided with a limiting groove communicated with the mounting groove, and one end of the torsion spring is inserted into the limiting groove.

[0015] According to some embodiments of the utility model, the locking member is provided with a limiting hole, and the other end of the torsion spring is inserted into the limiting hole, wherein the axis of the limiting hole is parallel to the rotation center axis of the locking member and is arranged at intervals.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Combination Figure 1 and Figure 2 The present application relates to an easy-to-operate lamp tube clamping mechanism 100, which includes a first clamping member 110, a second clamping member 120 and a locking assembly 130. The first clamping member 110 and the second clamping member 120 are used to clamp an object. The locking assembly 130 is used to buckle the first clamping member 110 and the second clamping member 120 together, thereby ensuring that the first clamping member 110 and the second clamping member 120 continue to apply a clamping force to the object to prevent the object from falling off.

[0037] The object clamped by the easy-to-operate lamp tube clamping mechanism 100 may be a tubular structure, such as the lamp tube 200. Of course, in other embodiments, the object clamped by the easy-to-operate lamp tube clamping mechanism 100 may also be a structure of other shapes.

[0038] like Figure 3 As shown, the first end of the first clamping member 110 is rotatably connected to the first end of the second clamping member 120, and the second end of the first clamping member 110 and the second end of the second clamping member 120 can approach or move away from each other due to the relative rotation of the first clamping member 110 and the second clamping member 120.

[0039] It should be noted that the first end of the first clamping member 110 and the second end of the first clamping member 110 are opposite ends, and the first end of the second clamping member 120 and the second end of the second clamping member 120 are opposite ends.

[0040] The first end of the first clamping member 110 and the first end of the second clamping member 120 are rotatably connected via the rotating shaft 140, and there is a damping feeling between the rotating shaft 140 and the first clamping member 110 or the second clamping member 120. In this way, on the one hand, the user's hand feeling during operation can be improved, and on the other hand, the second clamping member 120 can be rotated more slowly relative to the first clamping member 110.

[0041] Furthermore, a first half groove is provided on one side of the first clamping member 110, and a second half groove is provided on one side of the second clamping member 120. When the second end of the first clamping member 110 is docked with the second end of the second clamping member 120, the first half groove is opposite to the second half groove, and the first half groove and the second half groove cooperate to form a clamping hole 101, which is used for the lamp tube 200 to pass through.

[0042] When it is necessary to clamp the lamp tube 200, the lamp tube 200 can be first placed in the first half groove of the first clamping member 110, and then the second clamping member 120 can be rotated to make the second end of the second clamping member 120 gradually approach the second end of the first clamping member 110, so that the second clamping member 120 and the first clamping member 110 can clamp the lamp tube 200 together; when the second clamping member 120 is rotated into place, the locking assembly 130 buckles the first clamping member 110 and the second clamping member 120 together, thereby ensuring that the first clamping member 110 and the second clamping member 120 continue to apply clamping force to the object to prevent the object from falling off.

[0043] Combination Figure 3 and Figure 4 The locking assembly 130 includes a locking member 131 and an elastic reset member 132 . The locking member 131 is rotatably disposed on the second end of the first clamping member 110 , and the elastic reset member 132 is disposed on the first clamping member 110 and connected to the locking member 131 .

[0044] It is understandable that the locking member 131 is disposed at the second end of the first clamping member 110 , and the locking member 131 can be rotated by a user, and the elastic reset member 132 can provide a reset force to the locking member 131 .

[0045] Combination Figure 4 and Figure 6The second end of the second clamping member 120 is provided with a locking groove 121, and the second end of the second clamping member 120 is provided with a guide portion 122. When the second end of the second clamping member 120 moves toward the second end of the first clamping member 110, the guide portion 122 can force the locking member 131 to rotate in the unlocking direction so that the locking member 131 passes through the notch of the locking groove 121 and enters the locking groove 121 through the notch of the locking groove 121. The elastic reset member 132 can drive the locking member 131 to rotate in the locking direction after the locking member 131 passes through the notch of the locking groove 121 and enters the locking groove 121 to buckle the second clamping member 120.

[0046] It can be understood that in the process of rotating the second clamping member 120 so that the second end of the second clamping member 120 moves toward the second end of the first clamping member 110, the guide portion 122 will first press the locking member 131 to make the locking member 131 rotate in the unlocking direction so that the locking member 131 passes through the notch of the locking groove 121. When the locking member 131 passes through the notch of the locking groove 121, as the second end of the second clamping member 120 continues to move toward the second end of the first clamping member 110, the locking member 131 will enter the locking groove 121 through the notch of the locking groove 121. Thereafter, under the action of the elastic return member 132, the locking member 131 will rotate in the locking direction and extend into the interior of the locking groove 121, thereby buckling the second clamping member 120, thereby realizing the buckling connection between the second end of the first clamping member 110 and the second end of the second clamping member 120.

[0047] It should be noted that the unlocking direction and the locking direction are two opposite directions.

[0048] When the lamp tube clamping mechanism 100 of the utility model is easy to operate, if it is necessary to clamp an object between the first clamping member 110 and the second clamping member 120, it is only necessary to place the object on the first clamping member 110 and then rotate the second clamping member 120 until the second clamping member 120 is buckled by the locking member 131. No manual locking is required, and the operation is simple.

[0049] It is understandable that after the locking assembly 130 fastens the second end of the first clamping member 110 and the second end of the second clamping member 120 together, if unlocking is required, it is only necessary to rotate the locking member 131 so that the locking member 131 rotates in the unlocking direction, and then flip open the second clamping member 120.

[0050] Combination Figure 5 and Figure 6In some embodiments, a locking column 1311 is provided on the locking member 131, and the locking column 1311 is parallel to and spaced from the rotation center axis of the locking member 131, and the locking groove 121 extends in an arc shape; when the second end of the second clamping member 120 moves toward the second end of the first clamping member 110, the guide portion 122 can force the locking member 131 to rotate in the unlocking direction so that the locking column 1311 passes through the notch of the locking groove 121 and enters the locking groove 121 through the notch of the locking groove 121, and the elastic reset member 132 can drive the locking member 131 to rotate in the locking direction after the locking column 1311 passes through the notch of the locking groove 121 and enters the locking groove 121, so that the locking column 1311 buckles the second clamping member 120.

[0051] Specifically, in the process of rotating the second clamping member 120 so that the second end of the second clamping member 120 moves toward the second end of the first clamping member 110, the guide portion 122 will first press the locking column 1311 to make the locking member 131 rotate in the unlocking direction so that the locking column 1311 passes through the notch of the locking groove 121. When the locking column 1311 passes through the notch of the locking groove 121, as the second end of the second clamping member 120 continues to move toward the second end of the first clamping member 110, the locking column 1311 will enter the locking groove 121 through the notch of the locking groove 121. Afterwards, under the action of the elastic return member 132, the locking member 131 will rotate in the locking direction, so that the locking column 1311 extends into the interior of the locking groove 121, thereby buckling the second clamping member 120.

[0052] It should be noted that the guide portion 122 has a guide surface 1221, and the guide surface 1221 is inclined. When the second clamping member 120 is rotated so that the second end of the second clamping member 120 moves toward the second end of the first clamping member 110, the guide surface 1221 will first press the locking column 1311 to make the locking member 131 rotate along the unlocking direction so that the locking column 1311 passes through the notch of the locking groove 121.

[0053] like Figure 7 As shown, in some embodiments, a positioning groove 114 is provided at the second end of the first clamping member 110 , and the guide portion 122 extends into the positioning groove 114 when the second end of the second clamping member 120 is docked with the second end of the first clamping member 110 .

[0054] It is understandable that when the first clamp 110 and the second clamp 120 are locked together, the guide portion 122 extends into the positioning groove 114, which can further achieve the positioning of the first clamp 110 and the second clamp 120 and reduce the risk of the first clamp 110 and the second clamp 120 loosening.

[0055] Combination Figure 4 and Figure 5In some embodiments, the locking member 131 has a positioning column 1312, which is rotatably matched with the first clamping member 110. The elastic return member 132 is a torsion spring, which is sleeved outside the positioning column 1312, and one end of the torsion spring is clamped to the first clamping member 110, and the other end of the torsion spring is clamped to the locking member 131.

[0056] It can be understood that one end of the torsion spring is the first clamping portion 1321, and the other end of the torsion spring is the second clamping portion 1322. The torsion spring is sleeved outside the positioning column 1312, and the first clamping portion 1321 is clamped with the first clamping member 110, and the second clamping portion 1322 is clamped with the locking member 131. In this way, when the locking member 131 rotates in the unlocking direction, the torsion spring can apply a reset force to the locking member 131, so that the locking member 131 has a tendency to rotate in the locking direction.

[0057] Furthermore, a mounting groove 112 is disposed at the second end of the first clamping member 110 . A connecting column 111 is disposed inside the mounting groove 112 . The positioning column 1312 is rotatably sleeved outside the connecting column 111 .

[0058] Specifically, the connecting column 111 is provided with a middle hole, the positioning column 1312 is sleeved outside the connecting column 111, and a locking member 133 can be passed through the middle hole and limit the locking member 131 to prevent the locking member 131 from being separated from the first clamping member 110. The locking member 133 is a screw, and the middle hole is a screw hole.

[0059] Among them, the second end of the first clamping member 110 is also provided with a limiting groove 113 connected to the installation groove 112, the first clamping portion 1321 of the torsion spring is penetrated into the limiting groove 113, the locking member 131 is provided with a limiting hole 1313, and the second clamping portion 1322 of the torsion spring is penetrated into the limiting hole 1313.

[0060] Combination Figure 3 and Figure 8 In some embodiments, a spring sheet 150 is disposed at the second end of the first clamping member 110 , and the spring sheet 150 is located on the movable path of the second end of the second clamping member 120 .

[0061] It is understandable that when the second end of the second clamping member 120 is docked with the second end of the first clamping member 110, the second end of the second clamping member 120 presses the spring piece 150. After the lock assembly 130 buckles the second end of the first clamping member 110 and the second end of the second clamping member 120 together, if unlocking is required, the lock member 131 can be rotated to rotate the lock member 131 in the unlocking direction. When the lock column 1311 rotates to the notch of the lock slot 121, the spring piece 150 can automatically pop open the second end of the second clamping member 120, so that a gap is generated between the second end of the second clamping member 120 and the second end of the first clamping member 110, so that it is convenient for the user to flip over the second clamping member 120, and the purpose of quickly removing the lamp tube 200 is achieved. At the same time, after the second end of the second clamping member 120 is bounced open by the spring piece 150, the locking member 131 can quickly detach from the locking groove 121 from the notch of the locking groove 121, thereby reducing the risk of the locking member 131 turning back into the locking groove 121 under the action of the elastic return member 132.

[0062] Specifically, the second end of the first clamping member 110 is provided with a mounting groove 115 , the elastic sheet 150 is disposed in the mounting groove 115 , and the elastic sheet 150 protrudes from the surface of the second end of the first clamping member 110 .

[0063] The spring piece 150 can be fixed on the first clamping member 110 by a fastener 151 .

[0064] Optionally, the fastener 151 is a screw.

[0065] like Figure 3 As shown, in some embodiments, a buffer pad 160 is disposed on a side of the second clamping member 120 close to the first clamping member 110 .

[0066] In some other embodiments, a buffer pad is disposed on one side of the first clamping member 110 close to the second clamping member 120 .

[0067] In some other embodiments, a buffer pad 160 is disposed on a side of the second clamping member 120 close to the first clamping member 110 , and a buffer pad is disposed on a side of the first clamping member 110 close to the second clamping member 120 .

[0068] It can be understood that the buffer pad 160 can play a role of buffering and protecting the lamp tube 200, and the buffer pad 160 can also provide a pre-tightening force to further improve the stability of the lamp tube 200 being clamped.

[0069] The buffer pad 160 is an elastic silicone pad.

[0070] During use of the easy-to-operate lamp tube clamping mechanism 100 of the utility model, when it is necessary to clamp the lamp tube 200, the lamp tube 200 can be first placed in the first half groove of the first clamping member 110, and then the second clamping member 120 can be rotated to make the second end of the second clamping member 120 gradually approach the second end of the first clamping member 110, so that the second clamping member 120 and the first clamping member 110 can clamp the lamp tube 200 together; when the second clamping member 120 is rotated into place, the locking assembly 130 buckles the first clamping member 110 and the second clamping member 120 together, thereby ensuring that the first clamping member 110 and the second clamping member 120 continue to apply clamping force to the object to prevent the object from falling off. Among them, in the process of rotating the second clamping member 120 so that the second end of the second clamping member 120 moves toward the second end of the first clamping member 110, the guide portion 122 will first press the locking member 131 to make the locking member 131 rotate in the unlocking direction so that the locking member 131 passes through the notch of the locking groove 121. When the locking member 131 passes through the notch of the locking groove 121, as the second end of the second clamping member 120 continues to move toward the second end of the first clamping member 110, the locking member 131 will enter the locking groove 121 through the notch of the locking groove 121. Thereafter, under the action of the elastic return member 132, the locking member 131 will rotate in the locking direction and extend into the interior of the locking groove 121, thereby buckling the second clamping member 120, thereby realizing the buckling connection between the second end of the first clamping member 110 and the second end of the second clamping member 120. When the lamp tube clamping mechanism 100 of the utility model is easy to operate, if it is necessary to clamp an object between the first clamping member 110 and the second clamping member 120, it is only necessary to place the object on the first clamping member 110 and then rotate the second clamping member 120 until the second clamping member 120 is buckled by the locking member 131. No manual locking is required, and the operation is simple.
