[0036] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] In the present invention, by applying the movable locking mechanism provided by the present invention to the structure of the first movable member and the second movable member that can slide relative to each other, the first movable member and the second movable member can slide relative to each other, that is, the first movable member and the second movable member can be relatively expanded or contracted, so that the first movable member and the second movable member slide under limited force conditions during the expansion or contraction process, so that there will be no infinite relative sliding between the first movable member and the second movable member.

[0038] Example 1

[0039] like Figures 1 to 5As shown, the mobile locking mechanism provided by the embodiment of the present invention includes a fixing member 10, a locking member 20 and a first pre-tightening device 30. In the present embodiment, the fixing member 10 is used to be fixed on the first moving member, the fixing hoop 101 is fixedly connected to the first moving member, the locking member 20 is rotatably arranged in the mounting groove 11, and the locking member 20 passes through the mounting groove 11 and abuts against the second moving member. The locking member 20 can move in a direction away from the second moving member. During the rotation of the locking member 20, the abutment force between the locking member 20 and the second moving member gradually increases or gradually decreases. The first pre-tightening device 30 is arranged on the first moving member, and the first pre-tightening device 30 provides a pre-tightening force to the locking member 20. The pre-tightening force is the force that the first pre-tightening device 30 causes the locking member 20 to abut against the second moving member.

[0040] The locking member 20 abuts against the second moving member, so that the second moving member always abuts against the second moving member during the movement, that is, the second moving member can be stationary relative to the first moving member even when not subject to external force. Therefore, after the second moving member moves relative to the first moving member, the second moving member will not suddenly shrink rapidly relative to the first moving member after the force applied to the second moving member is withdrawn, and the abutting force between the locking member 20 and the second moving member gradually increases or decreases, which means that the abutting force of the locking member 20 on the second moving member gradually increases during the forward rotation of the locking member 20. At this time, the locking member 20 locks the second moving member with the first moving member as the fulcrum; on the contrary, when the locking member 20 rotates in the reverse direction, the abutting force of the locking member on the second moving member gradually decreases. At this time, the locking member 20 releases the second moving member with the first moving member as the fulcrum, thereby unlocking.

[0041] In this embodiment, the first movable member and the second movable member can both be rods, and the first movable member is a hollow cylindrical rod. The second movable member is inserted into the through hole of the first movable member to achieve a coaxial setting. The locking member is fixed on the first movable member, and the second movable member can slide relative to the first movable member. In this way, the first movable member and the second movable member form a two-section telescopic rod structure.

[0042] In addition, the first movable member and the second movable member may also be any other solid structure. In this case, the second movable member is arranged outside the first movable member, and the locking member is arranged on the first movable member and can abut against the second movable member.

[0043] The application of the movable locking mechanism provided by the present invention not only simplifies the assembly structure and is easy to operate, but also after the telescopic adjustment is completed, the first pre-tightening device 30 can cooperate with the locking member 20 to self-lock the second movable member, preventing the second movable member from automatically and quickly sliding relative to the first movable member and hitting someone, thereby eliminating safety hazards.

[0044] Specifically, the fixing member 10 includes a fixing hoop 101 and a fixing lock cap 102. The fixing hoop 101 and the fixing lock cap 102 are provided with a mounting groove 11. The fixing member 10 adopts a split structure to facilitate the installation of the locking member 20.

[0045] Example 2

[0046] like Figure 2 、 Figure 3 and Figure 5 As shown, the locking member 20 of the movable locking mechanism includes a locking portion 21. The locking portion 21 is rotatably connected to the mounting groove 11. The locking portion 21 is provided with a surface 211 that abuts against the second movable member, and the surface 211 is a curved surface. Specifically, in this locking portion 21, the rotational connection between the setting locking portion 21 and the mounting groove 11 is a fixed point (i.e., the position of the following connecting shaft 23), then the surface 211 includes a first point 2111 and a second point 2112, the surface 211 includes a first point 2111 nearest to the fixed point and a second point 2112 farthest from the fixed point, and the distance between the surface 211 and the fixed point gradually increases in sequence from the first point 2111 to the second point 2112 direction, that is, during the rotation process of the locking portion 21, the position where the surface abuts the second moving member rotates from the first point 2111 to the second point 2112 or moves from the second point 2112 to the first point 2111, the abutting force between the locking portion 21 and the second moving member can gradually increase or gradually decrease, during the rotation process, the abutting force between the locking portion 21 and the second moving member gradually increases, the second moving member can be locked relative to the first moving member, the abutting force between the locking portion 21 and the second moving member gradually decreases, then the second moving member is unlocked relative to the first moving member.

[0047] In addition, the distance between the surface 211 and the fixed point gradually increases in sequence from the first point 2111 to the second point 2112, so that the abutment force between the locking part 21 and the second movable part increases or decreases linearly during the rotation process, that is, the change in the abutment force is a uniform increase or decrease, which can avoid the sudden increase or sudden decrease of the abutment force causing the adjustment to be out of control.

[0048] In the locking member 20 of this embodiment, the surface 211 is provided with an anti-slip portion (not shown) for increasing friction. The provision of the anti-slip portion can increase the friction between the locking member 20 and the second movable member, thereby increasing the abutting force of the surface 211 on the second movable member during the relative sliding movement of the first movable member and the second movable member. The anti-slip portion can be an anti-slip member fixedly disposed on the surface 211, such as an anti-slip rubber pad; the anti-slip portion can also be one of ridges, bumps, grooves, or any combination thereof, provided on the surface 211.

[0049] like Figure 2 and Figure 3 As shown, specifically, when the locking member 20 is assembled, a connecting shaft 23 is provided in the mounting groove 11, and the locking member 20 is connected to the connecting shaft 23, so that the locking member 20 can rotate around the central axis of the connecting shaft 23. When the abutting force between the locking portion 21 and the second movable member gradually increases, pressure is applied to the first pre-tightening device 30, and the relative force of the first pre-tightening device 30 causes the connecting shaft 23 to drive the locking member 20 to move as a whole, that is, the connecting shaft 23 can drive the locking member 20 to move relative to the second movable member in a direction away from the second movable member.

[0050] Example 3

[0051] The locking member 20 of the movable locking mechanism further includes an operating lever 22. In practice, the locking portion 21 and the operating lever 22 are integrally formed and molded using a casting process. The operating lever 22 is connected to the locking portion 21, and one end of the operating lever 22 extends outside the mounting slot 11. The extended portion of the operating lever 22 can be manually operated. By moving the operating lever 22, the abutment force between the locking portion 21 and the second movable member can be quickly minimized, thereby achieving rapid unlocking.

[0052] Example 4

[0053] Furthermore, the mounting groove 11 has accommodating grooves 111 formed on the opposite side walls thereof. The fixing member 10 has a strip-shaped hole 112 on the side of the accommodating groove 111 close to the second movable member, into which the end of the connecting shaft 23 is inserted. The strip-shaped hole 112 extends toward the second movable member, and the first pre-tightening device 30 is provided between the accommodating groove 111 and the connecting shaft 23, that is, the first pre-tightening device 30 is assembled between the connecting shaft 23 and the fixed locking cap 102. Initially, under the action of the first pre-tightening device 30, the connecting shaft 23 always abuts against the end of the strip-shaped hole 112 close to the second movable member. When the abutting force between the locking member 20 and the second movable member gradually increases, pressure is applied to the first pre-tightening device 30. The relative action of the first pre-tightening device 30 causes the connecting shaft 23 to drive the locking member 20 to move away from the second movable member.

[0054] In this embodiment, the first pre-tightening device 30 is a U-shaped spring, and the assembly is completed by compression and pre-tightening; the first pre-tightening device 30 can also be a coil spring.

[0055] Example 5

[0056] The present invention takes a lighting fixture as an example to explain in detail the application of the above-mentioned movable locking mechanism.

[0057] like Figure 6 、 Figure 11As shown, the lighting fixture includes a main body 201 , a telescopic rod 202 , a lamp head assembly 203 , a power supply assembly 204 , a support rod 205 , a locking assembly 208 and the aforementioned moving locking mechanism 100 .

[0058] Specifically, the main body 201 includes a first end and a second end disposed opposite each other, and a collar 2011 is movably disposed on the main body 201. In this embodiment, the main body 201 is a rod-shaped member, and the collar 2011 is sleeved on the main body 201 and is movable along the axis of the main body 201. The telescopic rod 202 is movably disposed on the main body 201 and can extend beyond the first end of the main body 201. The lamp head assembly 203 is disposed on the end of the telescopic rod 202 that extends beyond the main body 201. The lamp light source of the lamp head assembly 203 emits light for illumination, and the power supply assembly 204 is disposed at the second end of the main body 201 to provide electrical energy to the lamp head assembly 203.

[0059] The lighting fixture is provided with at least three support rods 205 (this embodiment is described using three support rods 205). The three support rods 205 are evenly distributed around the circumference. During assembly, one end of each support rod 205 is movably connected to a collar 2011. When the collar 2011 moves on the main body 201, the three support rods 205 can be unfolded or folded relative to the main body 201. When unfolded, the three support rods 205 form a highly stable tripod. A locking assembly 208 is provided on the collar 2011. Once the collar 2011 is moved into position on the main body 201, the locking assembly 208 locks the collar 2011, which is moved to a suitable position on the main body 201, thereby maintaining the stability of the tripod formed by the three support rods 205. The fixing part 10 of the movable locking mechanism 100 is arranged on the main body 201, and the locking part 20 can abut against the telescopic rod 202, that is, the main body 201 serves as the above-mentioned first movable part, and the telescopic rod serves as the second movable part. The locking part 20 of the movable locking mechanism 100 and the first pre-tightening device 30 lock or unlock the telescopic rod, thereby realizing raising or lowering the lamp head assembly 203.

[0060] In this embodiment, the telescopic rod 202 can be a single piece or multiple pieces can be nested and telescopically connected to each other. When the telescopic rod 202 is a multiple-piece telescopic connection, taking two sections of rods as an example, at this time, the two sections of the telescopic rod 202 are the above-mentioned first moving member and the second moving member, and the first moving member and the second moving member are connected by the above-mentioned moving locking mechanism 100, thereby realizing locking or unlocking between the first moving member and the second moving member.

[0061] The height of the lamp head assembly 203 is adjusted by extending or retracting the telescopic rod 202. Since no components are installed between the main body 201 and the telescopic rod 202, when the telescopic rod 202 is extended, the distance between the end of the telescopic rod 202 extending outside the main body 201 and the second end of the main body 201 is at its maximum. This increases the telescopic travel of the telescopic rod 202 relative to the main body 201, thereby maximizing the telescopic height of the lamp head assembly 203 of the lighting fixture. Furthermore, the aforementioned movement locking mechanism 100 is employed between the main body 201 and the telescopic rod 202 to resist the sliding movement of the telescopic rod 202 relative to the main body 201, preventing the telescopic rod 202 from descending indefinitely relative to the main body 201 without external force. This prevents accidents in which the lamp head assembly 203 could fall rapidly and injure someone, thus ensuring safety.

[0062] Example 6

[0063] See also Figure 6 、 Figure 11 Furthermore, the main body 201 is provided with a plurality of positioning holes 2012, and the plurality of positioning holes 2012 are spaced apart from each other in the direction from the first end to the second end of the main body 201, and the locking assembly 208 includes a positioning pin 2081, such as Figure 11 As shown, the positioning pin 2081 can be inserted into or disengaged from the positioning hole 2012 . When the positioning pin 2081 is disengaged from the positioning hole 2012 , the collar 2011 can move on the main body 201 .

[0064] When the collar 2011 moves to an appropriate position on the main body 201 (the position of the collar 2011 is determined by the corresponding positioning hole 2012), the positioning pin 2081 is inserted into the positioning hole 2012 to lock the collar 2011 on the main body 201 (when the positioning pin 2081 is pulled out, that is, the positioning pin 2081 is out of the positioning hole 2012, the collar 2011 can slide on the main body 201).

[0065] When the lighting fixture is stored, the three support rods 205 are adjacent to each other and combined to form a cylinder that is stored on the main body 201. Figure 10When the three support rods 205 need to be unfolded to support the lamp head assembly 203, one only needs to hold one of the support rods 205 and pull it, which can drive the collar 2011 to move along the axis of the main body 201. When the tripod formed by the three support rods 205 is unfolded to a certain angle so as to stably support the lamp head assembly 203, the positioning pins 2081 on the collar 2011 are inserted into the corresponding positioning holes 2012, thereby stabilizing the tripod formed by the three support rods 205. When the tripod needs to be stored, the positioning pins 2081 are pulled out of the positioning holes 2012, and then the collar 2011 is moved to the first end position of the main body 201. At this time, the three support rods 205 are reassembled into a cylindrical body for storage.

[0066] Example 7

[0067] like Figure 6 and Figure 7 As shown, further, each support rod 205 is rotatably provided with a connecting rod 206, and one end of the connecting rod 206 not connected to the support rod 205 is movably connected to the second end of the main body 201. Figure 10-11 As shown, the locking assembly 208 includes a movable member 2083 and a second preload device 2082. The movable member 2083 is inserted into the collar 2011 and is connected to a corresponding one of the support rods 205. When the movable member 2083 is pulled, only one support rod 205 needs to be pulled apart to simultaneously pull apart all the support rods 205. This allows the support rods 205 to be quickly deployed relative to the main body, making the operation quick and easy. The positioning pin 2081 is disposed on the side of the movable member 2083 near the main body 201. When the support rod 205 is deployed relative to the main body 201, the movable member 2083 is pulled, and the movable member 2083 drives the positioning pin 2081 to be pulled out of the positioning hole 2012. The second preload device 2082 is disposed on the collar 2011 and provides a preload force to the movable member 2083 to insert and position the positioning pin 2081.

[0068] See also Figure 9 Furthermore, the support rod 205 connected to the movable part 2083 is provided with a handle 2051 to facilitate personnel to operate the support rod 205. Furthermore, two vacancies 2052 are opened on the support rod 205, and the area between the two vacancies 2052 forms the handle 2051, thereby simplifying the design structure of the support rod 205.

[0069] like Figure 11As shown, in this embodiment, the second pre-tightening device 2082 adopts a helical compression spring, and two of them are provided. The two second pre-tightening devices 2082 are respectively provided on opposite sides of the movable member 2083 so that the movable member 2083 can move smoothly during movement. A movable groove 20111 is formed in the collar 2011, and a limiting hole is formed at the bottom of the movable groove 20111. The movable member 2083 is placed in the movable groove 20111. The movable member 2083 extends a convex edge, and one end of the helical compression spring abuts against the convex edge. Two helical compression springs are respectively provided on either side of the movable member 2083. The movable member 2083 is then fixedly connected to the collar 2011 via a mounting cover 2084. The mounting cover 2084 covers the movable groove 20111 so that the other end of the helical compression spring abuts against the mounting cover 2084. One end of the movable member 2083 extends through the mounting cover. The end of a corresponding support rod 205 is connected to the end of the movable member 2083. A positioning pin 2081 is provided at the other end of the movable member 2083 and extends through the limiting hole. In this embodiment, the positioning pin 2081 is integrally formed with the movable member 2083.

[0070] Example 8

[0071] See also Figure 8 Specifically, the lamp head assembly 203 includes a lamp holder 2031 and a light-emitting assembly 2032. The lamp holder 2031 includes a base 20311 fixed to the end of the telescopic rod 202, and a fixed rod 20312 having one end fixed to the base 20311 and the other end extending toward the main body 201. The light-emitting assembly 2032 is rotatably connected to the end of the fixed rod 20312 facing the main body 201. The light-emitting assembly 2032 can be unfolded relative to the telescopic rod 202 or folded on the fixed rod 20312 around this connection. In this way, the light-emitting component 2032 can rotate with the end of the fixing rod 20312 facing the main body 201 as the vertex. Compared with the structure in which the light-emitting component 2032 is directly rotated on the base 20311, this design structure can shorten the distance from the light-emitting component 2032 to the second end of the main body 201 when the light-emitting component 2032 is unfolded. When the lamp is placed upright on the ground for use, the lighting distance from the light-emitting component 2032 to the ground can be shortened, so that the lighting is more sufficient.

[0072] Furthermore, there are multiple light-emitting components 2032, and the multiple light-emitting components 2032 are arranged around the base 20311, so that the multiple light-emitting components 2032 are spliced into a ring light, thereby increasing the lighting range of the lamp.

[0073] In order to further reduce the weight of the lighting fixture and to better connect the wiring between the power supply component 204 and the lamp head component 203, the main body 201 and the telescopic rod 202 are both hollow structures and are interconnected, and the connecting wires between the power supply component 204 and the lamp head component 203 are arranged through the hollow through holes.
