Description

Technical Field

[0001] The utility model belongs to the technical field of tents, and in particular relates to a contraction and locking structure of a tent support. Background Art

[0002] Tents are essential items for outdoor camping or setting up temporary shelters. A tent frame is a crucial component of a tent. The tent frame typically consists of a pivotal connection and multiple tent poles. The poles are pivotally connected to the pivotal connection and can rotate relative to the pivotal connection to fold and unfold the tent frame. However, tent poles are relatively long, so they are typically constructed from multiple poles connected by pivotal structures such as movable joints, allowing the poles to fold relative to each other to reduce the storage space required for the tent frame. However, the use of a pivotal connection allows the poles to fold, but they still occupy a certain amount of storage space when folded, failing to minimize storage space and making them inconvenient to carry. Furthermore, the pivotal connection between the poles is complex, requiring a limiting structure to limit the rotation angle of the poles and a locking structure to lock the poles. This results in high production costs and complex operation. Utility Model Content

[0003] The purpose of the utility model is to provide a retractable locking structure for a tent stand. The tent pole adopts a telescopic pole structure, which reduces the storage space to the greatest extent and only requires a locking structure, thereby reducing production costs and simplifying operation.

[0006] Furthermore, the limiting protrusion is arranged between the bottom wall and the side wall of the annular groove, and the notch is arranged at the bottom of the expansion sleeve.

[0007] Furthermore, the locking member includes a locking sleeve, a cam handle, and a locking block.

The end of the tent pole member is pivotally engaged with the pivot groove of the pivot seat, and the tent pole member can be rotated upward relative to the pivot seat to be folded. Before folding, most of the structure of the inner pole can be retracted into the outer pole to minimize the space occupied by the tent frame. After the tent frame is unfolded, the inner pole can be extended out of the outer pole for use. The tent pole member can be extended and retracted by simply providing a locking member structure for locking and unlocking the inner pole and the outer pole on the tent pole member, thereby reducing production costs and simplifying operation.

[0032] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1-14 As shown, the utility model provides a retractable locking structure of a tent stand, comprising a pivot seat 1, a tent pole 2 and a locking member 5; at least three pivot grooves 11 are radially formed on the pivot seat 1, and the ends of the tent pole 2 are pivotally connected in the pivot grooves 11 to form a tent stand structure. The tent pole 2 can be rotated upward relative to the pivot seat 1 to be folded, or rotated downward to be unfolded, thereby realizing the unfolding use and folding storage of the tent stand.

[0034] Specifically, the tent bracket also includes a lower cover 3 and a locking member 4, the part of the pivot groove 11 facing the center of the pivot seat 1 forms a ball socket 12, and the side wall of the pivot groove 11 forms a retaining edge 13 on the outer periphery of the ball socket 12, and the ball socket 12 passes through the bottom surface of the pivot seat 1; the end of the tent pole 2 forms a ball head 21 that cooperates with the ball socket 12, and the diameter of the ball head 21 is larger than the diameter of the tent pole 2, and the ball head 21 can be installed into the ball socket 12 from the bottom surface of the pivot seat 1, and then the lower cover 3 is fixed to the bottom surface of the pivot seat 1 by the locking member 4, and the retaining edge 13 and the lower cover 3 cooperate so that the ball head 21 is limited in the ball socket 12, and the cooperation between the ball head 21 and the ball socket 12 can realize the tent pole 2 to rotate upward relative to the pivot seat 1 and fold, and the folded state is as shown in FIG. Figure 4 As shown, on the contrary, turn it downward to unfold it. The unfolded state is as follows Figure 1 shown.

[0035] Key references Figure 2-3 The locking member 4 is a screw or a threaded rod, and the middle part of the pivot seat 1 and the lower cover 3 is provided with a mounting hole for the screw or the threaded rod to pass through. The lower part of the locking member 4 passes through the mounting holes of the pivot seat 1 and the lower cover 3 to fix the pivot seat 1 and the lower cover 3 together, which is convenient for installing the ball head 21, and the locking member 4 is locked in the center of the pivot seat 1 without occupying the space of the ball socket 12, and the layout is reasonable.

[0036] The present invention configures the tent pole 2 into a telescopic pole structure. Specifically, the tent pole 2 includes an inner pole 22 and an outer pole 23. The inner pole 22 is movably inserted into the outer pole 23. The inner pole 22 can move axially relative to the outer pole 23 to extend or retract into the inner pole 22, thereby achieving the telescopic movement of the tent pole 2. The locking member 5 is provided on the tent pole 2 to lock or unlock the inner pole 22 and the outer pole 23. Before folding, most of the structure of the inner pole 22 can be retracted into the outer pole 23 to minimize the space occupied by the tent stand. After the tent stand is unfolded, the inner pole 22 can be extended out of the outer pole 23 for use. After the telescopic adjustment of the tent pole 2 is completed, that is, after the inner pole 22 is moved into position, the inner pole 22 is locked and fixed with the locking member 5, thereby achieving the retraction and locking of the tent pole 2.

[0037] Furthermore, the ball head 21 is a sleeve structure, and the ball head 21 can be sleeved and fixed on the end of the inner rod 22. Specifically, one end of the inner rod 22 is movably inserted into the outer rod 23, and the other end of the inner rod 22 is sleeved and fixed with the ball head 21. Then, the locking member 5 can be set at one end of the inner rod 22, or at the end of the outer rod 23 connected to the inner rod 22. When the tent pole 2 is telescopically adjusted, the outer tube can be moved to move axially relative to the inner rod 22. Of course, the ball head 21 can also be sleeved and fixed on the end of the outer tube, and the inner rod 22 can be moved to adjust the telescopic movement of the tent pole 2.

[0038] The specific structure of the locking member 5 is further illustrated by the following embodiments:

[0039] Example 1:

[0040] Key references Figure 11-14The locking piece 5 is an expansion sleeve 51. The expansion sleeve 51 is a "C"-shaped sleeve with an opening, and the thickness of the middle part of the expansion sleeve 51 gradually decreases towards both ends to form an eccentric sleeve structure. A notch 511 is provided between the middle part of the expansion sleeve 51 and one end thereof. The end of the notch 511 close to the middle part of the expansion sleeve 51 is the maximum expansion point 512, and the end close to the end of the expansion sleeve 51 is the minimum expansion point 513; one end of the inner rod 22 is provided with an annular mounting groove 521, and the expansion sleeve 51 is sleeved on the mounting groove 521. The expansion sleeve 51 is made of deformable material and can be easily sleeved on the mounting groove 521 through the opening. The mounting groove 521 is provided with a limiting protrusion 522, and the limiting protrusion 522 cooperates with the notch 511. Specifically, when the inner rod 22 is rotated, the limiting protrusion 522 will rotate accordingly and push against the two ends of the notch 511. When the limiting protrusion 522 pushes the minimum expansion point 513, the end of the expansion sleeve 51 close to the minimum expansion point 513 is pushed toward the other end, and the opening of the expansion sleeve 51 is reduced. Then, the expansion sleeve 51 is contracted as a whole and loosens the inner wall of the outer rod 23. The outer rod 23 is unlocked, and the contracted state of the expansion sleeve 51 is as shown in FIG. Figure 14 On the contrary, when the limiting protrusion 522 pushes against the maximum expansion point 512, the expanded middle part of the expansion sleeve 51 is acted upon by the thrust, so that the opening of the expansion sleeve 51 gradually becomes larger, and the expansion sleeve 51 expands as a whole and tightens the inner wall of the outer rod 23, and the outer rod 23 is locked and cannot move. The expansion state of the expansion sleeve 51 is as shown Figure 13 shown.

[0041] Further, Figure 11 and Figure 12 For reference, the inner rod 22 is positioned below the outer rod 23. The stopper protrusion 522 is positioned between the bottom and side walls of the annular groove. The notch 511 is located at the bottom of the expansion sleeve 51, ensuring that the stopper protrusion 522 does not disengage from the notch 511. To facilitate processing, a connecting sleeve 52 can be fixed to one end of the inner rod 22. The connecting sleeve 52 has flanges at its top and middle, with a mounting groove 521 formed between the two flanges.

[0042] Example 2:

[0043] Key references Figure 5-8The locking member 5 includes a locking sleeve 53, a cam handle 54, and a locking block 55. The locking sleeve 53 is sleeved on the outer rod 23, specifically, it can be sleeved on one end of the outer rod 23 connected to the inner rod 22. One end of the cam handle 54 is a cam end 541, and the other end is a hand-driven end 542. The cam end 541 is pivotally connected to the locking sleeve 53. The locking sleeve 53 and the outer rod 23 are provided with an active cavity 531 for sliding cooperation of the locking block 55. The hand-driven end 542 is used to manually drive the cam end 541 to rotate, so that the cam end 541 pushes the locking block 55 to press the inner rod 22, and the inner rod 22 cannot move and is locked, or the locking block 55 is released to unlock the inner rod 22. At this time, the inner rod 22 can move relative to the outer rod 23 to complete the telescopic adjustment of the tent pole 2.

[0044] Specifically, the position where the cam end 541 is pivotally connected to the locking sleeve 53 is the pivot point 543. The maximum distance between the central outer peripheral surface of the cam end 541 and the pivot point 543 is the locking surface 544. The minimum distance between the outer peripheral surface of the end of the cam end 541 away from the hand-driven end 542 and the pivot point 543 is the unlocking surface 545. The distance between the outer peripheral surface of the cam end 541 and the pivot point 543 gradually decreases from the locking surface 544 to the unlocking surface 545, so that the cam end 541 rotates to When the locking surface 544 abuts the locking block 55, the hand-driven end 542 is parallel to the outer rod 23, and the locking block 55 is pushed by the locking surface 544 and moves radially inward until the inner rod 22 is pressed and the state of pressing the inner rod 22 is maintained. When the cam end 541 rotates until the unlocking surface 545 is opposite to the locking block 55, the hand-driven end 542 is perpendicular to the outer rod 23 and the locking block 55 is not pushed. At this time, when the inner rod 22 or the outer rod 23 is moved, the locking block 55 will be pushed outward and the inner rod 22 will be unlocked.

[0045] Furthermore, a limit block 534 is protruding from the movable cavity 531, and a limit groove 551 is provided on one side surface of the locking block 55 corresponding to the limit block 534. The limit groove 551 is arranged along the sliding direction of the locking block 55, that is, radially. When the locking block 55 moves radially, the limit block 534 moves in the limit groove 551, that is, the limit block 534 is limited in the limit groove 551, preventing the locking block 55 from separating from the movable cavity 531. Specifically, a pivot portion 532 is radially protruded on the outer periphery of the locking sleeve 53, and a pivot cavity 533 is formed in the pivot portion 532. The cam end 541 is pivotally connected to the pivot cavity 533. The active cavity 531 is radially opened on the side wall of the locking sleeve 53 and connects the pivot cavity 533 and the interior of the locking sleeve 53. Restricted by the cam end 541 and the pivot portion 532, the locking block 55 will not move radially outward and escape from the active cavity 531. The limiting groove 551 is opened outward from the inner side surface of the locking block 55 until the middle of the locking block 55 forms a side wall. The side wall abuts against the limiting block 534 to limit the locking block 55 from moving radially inward and escaping from the active cavity 531, so as to prevent the locking block 55 from moving radially inward and escaping from the active cavity 531. Figure 5 With reference to the view of , the inner rod 22 is above the outer rod 23 , the limiting groove 551 can be provided on the bottom surface of the locking block 55 , and the limiting block 534 is correspondingly provided on the bottom wall of the active cavity 531 .

[0046] Example 3:

[0047] Key references Figure 9-10 The locking member 5 is a V-shaped spring piece 56, which is arranged inside the inner rod 22, and both ends of the V-shaped spring piece 56 abut against the inner rod 22. One end of the V-shaped spring piece 56 is provided with a button 57. The inner rod 22 is provided with a telescopic hole 581 for the telescopic movement of the button 57. Under the elastic force of the V-shaped spring piece 56, the button 57 is always located in the telescopic hole 581. A fixing hole 231 is provided on the outer rod 23. When the inner rod 22 moves relative to the outer rod 23, the V-shaped spring piece 56 moves accordingly until the button 57 is aligned with the fixing hole 231. The button 57 is affected by the elastic force of the V-shaped spring piece 56 and extends into the fixing hole 231 to clamp the outer rod 23. The inner rod 22 and the outer rod 23 are locked and cannot move relative to each other. To unlock the inner rod 22 and the outer rod 23, you only need to press the button 57 to make the button 57 exit the fixing hole 231. At this time, the inner rod 22 or the outer rod 23 can be moved relative to each other.

[0048] Furthermore, the inner rod 22 and outer rod 23 can both be square tube structures, i.e., both have rectangular cross-sections. One end of the inner rod 22 is axially movable and inserted into the outer rod 23. The V-shaped spring clip 56 is disposed within one end of the inner rod 22. The square tube structure restricts the inner rod 22 from axial movement relative to the outer rod 23, but not circumferential rotation relative to the outer rod 23, thereby preventing the button 57 and the fixing hole 231 from misaligning and thus failing to lock the inner rod 22 and the outer tube. Alternatively, the inner rod 22 can be a circular tube structure, while the outer rod 23 is a square tube structure. A connecting square tube 58 can be disposed at one end of the inner rod 22, axially movable within the outer rod 23, the V-shaped spring clip 56 disposed within the connecting square tube 58, and the telescopic hole 581 is disposed on a side wall of the connecting square tube 58. This arrangement also restricts relative rotation between the inner rod 22 and the outer rod 23, and the cross-sectional shape of the inner rod 22 is not limited to a rectangular shape.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the design of this case. Any equivalent changes made based on the key design of this case shall fall within the scope of protection of this case.
