[0029] Reference below Figures 1 to 5 The locking lifting bracket according to the embodiment of the present invention is described.

[0030] like Figures 1 to 3 As shown, according to an embodiment of the present invention, a locking lifting bracket includes: an outer cylinder clamp assembly 100, an inner cylinder 200 and a locking member 300. The top end of the outer cylinder clamp assembly 100 is provided with a plurality of clamping petals 121 distributed along the circumferential direction, and gaps are formed between adjacent clamping petals 121, and the plurality of clamping petals 121 can gather together or move away from each other; the inner cylinder 200 can be lifted and inserted into the top end of the outer cylinder clamp assembly 100; the locking member 300 is sleeved on the outer cylinder clamp assembly 100 and includes a supporting portion 310. The inner wall of the supporting portion 310 is provided with a guide surface, and the distance between the guide surface and the axial center line of the locking member 300 gradually decreases along the axial direction, so as to support the outer side of the clamping petals 121 to gather or release the clamping petals 121, so that the clamping petals 121 can clamp or release the inner cylinder 200.

[0031] It can be understood that this locking lifting bracket includes an outer cylinder clamp assembly 100, an inner cylinder 200 and a locking member 300. The inner cylinder 200 can be lifted and inserted into the top end of the outer cylinder clamp assembly 100. The top of the outer cylinder clamp assembly 100 is provided with a plurality of clamp petals 121 distributed along the circumferential direction. The locking member 300 is sleeved on the top of the outer cylinder clamp assembly 100 and can achieve abutment against the outer side of the clamp petal 121 through the guide surface of the inner wall of the abutting portion 310. Moreover, since the distance between the guide surface and the axis of the locking member 300 gradually decreases along the axial direction, it can be lifted and lowered as the lock is lifted. The axial movement of the tightening member 300 can achieve a gathering or releasing effect on the clamping petals 121. When the clamping petals 121 are gathered together, the inner cylinder 200 can be clamped and locked. When the locking member 300 releases the clamping petals 121, the inner cylinder 200 can slide relative to the outer cylinder clamp assembly 100, thereby adjusting the vertical position of the inner cylinder 200 relative to the outer cylinder clamp assembly 100, thereby avoiding the use of a gas spring to achieve the lifting and lowering adjustment of the inner cylinder 200; therefore, the locking lifting bracket of the present application can achieve the lifting and lowering adjustment of the display at a lower cost.

[0032] It is understood that a damping member 400 is also included. The damping member 400 is elastic and is provided on the inner cylinder 200 and abuts against the inner wall of the outer cylinder clamp assembly 100 to increase sliding damping. Figure 5 As shown, in this embodiment, in order to prevent the user from adjusting the inner cylinder 200 too much and causing multiple adjustments during the adjustment process, the friction between the elastic damping member 400 and the inner wall of the outer cylinder clamp assembly 100 is used to increase the user's adjustment feel and avoid excessive adjustment.

[0033] It is understood that the locking member 300 includes a first connecting portion 320 connected to the abutting portion 310, and the first connecting portion 320 is used to connect to the outer collet assembly 100. For example, Figures 1 to 3 As shown, in this embodiment, the first connecting portion 320 is provided to enable the locking member 300 to be locked on the outer collet assembly 100 , thereby improving the stability of the locking member 300 locking the outer collet assembly 100 .

[0034] Specifically, the first connecting portion 320 may be a sleeve having elasticity itself, and the sleeve may be clamped tightly on the outer collet assembly 100 , thereby achieving the connection between the locking member 300 and the outer collet assembly 100 .

[0035] It should be understood that the first connecting portion 320 may not be provided. For example, when the locking member 300 itself is made of elastic material, the connection with the outer collet assembly 100 is achieved through the interference fit between the abutting portion 310 and the clamping flap 121.

[0036] It is understood that the inner wall of the first connecting portion 320 is provided with an internal thread, and the outer collet assembly 100 includes a second connecting portion 122 connected to one end of the clamping petal 121, and the outer periphery of the second connecting portion 122 is provided with an external thread, and the connecting portion is threadedly connected to the outer collet assembly 100 through the external thread. Figures 3 and 4 As shown, in this embodiment, the first connecting portion 320 is provided with an internal thread, and the second connecting portion 122 connected to one end of the clamping flap 121 is provided with an external thread, so that the locking member 300 can be threadedly connected to the outer clamp assembly 100 through the first connecting portion 320, thereby achieving the gathering of the clamping flap 121 while locking it outside the outer clamp assembly 100.

[0037] It should be understood that, in addition to the threaded connection, the locking member 300 and the outer collet assembly 100 may also be fixedly connected by a snap-fit ​​connection.

[0038] It is understandable that the top of the locking member 300 is provided with an inner flange 330, and the inner flange 330 can abut against the top of the clip 121 to limit the locking member 300. For example, Figures 1 to 4 As shown, in this embodiment, an inner flange 330 is provided on the top of the locking member 300. When the locking member 300 is screwed to a certain extent outside the outer collet assembly 100, the inner flange 330 abuts against the top of the clamping petal 121, thereby limiting the axial movement of the locking member 300 and preventing the locking member 300 from rotating excessively, resulting in friction between the guide surface and the external thread of the second connecting portion 122, thereby avoiding the wear caused thereby.

[0039] It is understood that the outer collet assembly 100 includes a housing 110 and a collet 120. The collet 120 is detachably inserted into the housing 110, and the clamping flap 121 and the second connecting portion 122 are provided on the collet 120. For example, Figure 4 As shown, in this embodiment, the outer collet 120 component includes a housing 110 and a collet 120. The collet 120 having a clamping flap 121 and a second connecting portion 122 is detachably inserted into the housing 110. Therefore, as the use time increases, the worn or damaged collet 120 can be replaced, thereby saving costs.

[0040] It is understood that the collet 120 further includes a guide portion 123, which is connected to the end of the second connecting portion 122 away from the clamping flap 121. The side wall of the guide portion 123 is provided with a limiting groove 1231 arranged along the axial direction and not passing through the two ends. The inner cylinder 200 is correspondingly provided with a limiting member 210, and the limiting member 210 slides along the limiting groove 1231. For example, Figures 4 and 5As shown, in this embodiment, the collet 120 also includes a guide portion 123 provided at the end of the second connecting portion 122 away from the clamping petal 121, and a limiting groove 1231 is axially provided on the side wall of the guide portion 123, and the limiting member of the inner cylinder is limited to the limiting groove in the horizontal direction, thereby limiting the rotation of the inner cylinder in the horizontal direction; at the same time, the inner cylinder 200 can achieve vertical sliding along the limiting groove 1231 through the limiting member 210, and because the two ends of the limiting groove 1231 are not through-set, the inner cylinder 200 stops when it slides to the limiting member 210 abutting the two ends of the limiting groove 1231, thereby limiting the displacement of the inner cylinder 200 in the vertical direction, preventing the inner cylinder 200 from being too high and detaching from the outer cylinder clamp assembly 100 during the lifting and lowering adjustment process, or being too low and causing squeezing of other components on the bottom inner of the outer cylinder clamp assembly 100.

[0041] It is understood that a locking structure is provided between the housing 110 and the collet 120, and the locking structure includes a hanging buckle 124 provided on the collet 120 and a card slot 111 provided on the housing 110, one end of the hanging buckle 124 is connected to the end of the second connecting portion 122 away from the clamping flap 121, and the other end can be embedded in the card slot 111, and the other end of the hanging buckle 124 can move along the radial direction of the collet 120. For example, Figure 4 As shown, in this embodiment, the collet 120 is detachably connected to the housing 110 through a locking structure. The locking structure includes a card slot 111 provided on the side of the housing 110 and a hanging buckle 124 provided on the collet 120. The hanging buckle 124 is connected to the end of the second connecting portion 122 away from the clamping flap 121, and the end away from the second connecting portion 122 can be embedded in the card slot 111. Therefore, after the collet 120 is inserted into the top of the housing 110, the hanging buckle 124 can be embedded in the card slot 111, thereby realizing the locked connection between the collet 120 and the housing 110.

[0042] It is understandable that the second connection portion 122 is further provided with a positioning protrusion 1232 at one end away from the clip 121, and the top of the housing 110 is correspondingly provided with a positioning groove 112, and the positioning protrusion 1232 is adapted to the positioning groove 112. Figure 4 As shown, in this embodiment, when the collet 120 is inserted into the housing 110, the positioning protrusion 1232 provided on the second connecting portion 122 can be embedded in the positioning groove 112 on the top of the housing 110, thereby achieving positioning, thereby facilitating alignment and locking of the locking structure.

[0043] It is understood that a baffle 500 is also included. The inner cylinder 200 is used to connect to the display. The display wire 600 is passed through the inner cylinder 200 and the outer cylinder clamp assembly 100. The display wire 600 includes a straight portion 610 and a spiral portion 620 connected to one end of the straight portion 610. The spiral portion 620 is located at the bottom of the outer cylinder clamp assembly 100. The baffle 500 is provided on the straight portion 610 and is separated between the inner cylinder 200 and the spiral portion 620. For example, Figure 5 As shown, in this embodiment, a baffle 500 is provided between the straight portion 610 and the spiral portion 620 of the electric wire 600. The baffle 500 blocks the inner cylinder 200 and the spiral portion 620 of the electric wire 600. As a result, when the inner cylinder 200 descends, the straight portion 610 and the spiral portion 620 of the electric wire 600 are entangled. This ensures that the internal electric wire 600 always remains regular during use, and also prevents the spiral portion 620 from being squeezed when the inner cylinder 200 descends.

However, the present application is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application.
