Description

[0001] This application is a divisional application of the invention patent application No. 201710042277.4, filed on January 20, 2017. TECHNICAL FIELD

[0002] The present application relates to a tent, in particular a telescopic stand for a tent and a tent having the telescopic stand. BACKGROUND

[0003] Tents are mainly built temporarily in the open air, used for sheltering from wind and rain, shielding sunlight or temporary residence. The structure of a tent generally includes a tent cloth, a top support and a stand. In order to facilitate transportation and assembly, the top support of the existing tent mostly adopts a folding structure. However, since the stand needs to bear a large weight, it is generally of fixed length, occupying a large space during transportation. Only those light-weight tent structures have telescopic stands designed.

[0004] In the prior art, the telescopic stand is mainly fixed in length by a clamping piece, such as the telescopic stand for a tent disclosed in Chinese patent CN104196319A. However, the clamping piece is very easy to break due to local large stress during use, causing the dangerous situation of tent collapse to occur from time to time. SUMMARY

[0005] Therefore, in order to overcome the defects of the prior art, the first object of the present application is to provide a telescopic stand with more stable structure and greater bearing capacity.

[0006] In order to achieve the above object, first, the present application provides a telescopic stand comprising an inner tube and an outer tube which are mutually sleeved, and a locking mechanism for fixing the inner tube and the outer tube together, the inner tube having an open end portion inserted into the outer tube, a strip-shaped opening being formed in the side wall of the open end portion; the locking mechanism comprising a tensioning part for providing a tensioning force for expanding the open end portion outwardly in a direction perpendicular to the length direction of the inner tube, a cooperating assembly provided in the inner tube and cooperating with the tensioning part to tension the open end portion, and an operating hole corresponding to the tensioning part being formed in the side wall of the inner tube and the outer tube.

[0008] The strip-shaped openings are formed in the side wall of the open end, so that the side wall has a certain range of movement in the radial direction. The side wall of the open end can be expanded outward or contracted inward to a certain extent by the cooperation of the tensioning member and the matching assembly, so as to be tightly fixed or loosened with the outer tube.

[0016] In a specific embodiment, the elastic positioning member comprises a positioning pin arranged in the inner tube and a spring, and the positioning protrusion is arranged at one end of the positioning pin. The elastic force of the spring causes the positioning protrusion at one end of the positioning pin to protrude out of the through hole in the sidewall of the inner tube, and when the positioning hole in the sidewall of the outer tube is matched with the positioning protrusion on the positioning pin, the inner tube and the outer tube can be positioned.

[0018] The second object of the present application is to provide a tent comprising a cross beam and a top frame, and further comprising the telescopic stand of any of the above technical solutions.

DETAILED DESCRIPTION

[0033] The preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0034] Example One

[0035] Please refer to Figures 1 to 4 ​​​​The telescopic stand 100 of the present embodiment comprises an inner tube 10 and an outer tube 20 which are telescopically connected, and a locking mechanism which fixes the inner tube 10 and the outer tube 20 together. The inner tube 10 has an open end 110 which is inserted into the outer tube 20, and a strip-shaped opening 120 is formed in the side wall of the inner tube 10 and extends longitudinally to an open edge. The locking mechanism comprises a tensioning member which provides a tensioning force for expanding the open end 110 outwardly in a direction perpendicular to the length direction of the inner tube 10, a cooperating assembly which is arranged on the inner tube 10 and cooperates with the tensioning member to tension the open end 110, and operation holes corresponding to the tensioning member are formed in the side walls of the inner tube 10 and the outer tube 20. Specifically, an operation hole 101 is formed in the inner tube 10, and an operation hole 201 is formed in the outer tube 20.

[0036] The inner tube 10 and the outer tube 20 are both square tubes, and in some embodiments, at least two strip-shaped openings 120 are formed in at least two opposite sides of the side wall of the inner tube 10, and the at least two strip-shaped openings 120 divide the side wall of the open end of the inner tube 10 into at least two side wall deformation portions. For example, at least one strip-shaped opening 120 is formed in each of two opposite sides of the side wall of the inner tube 10, and the at least two strip-shaped openings 120 divide the side wall of the open end of the inner tube 10 into two side wall deformation portions, and each side wall deformation portion has two sides each comprising a side edge divided by the strip-shaped opening 120. The at least two strip-shaped openings 120 formed in the two opposite sides divide the side wall of the open end of the inner tube 10 into two U-shaped side wall deformation portions, and each side wall deformation portion has two sides each comprising a corner 170, and each corner 170 comprises at least one side edge.

[0037] In the present embodiment, one strip-shaped opening 120 is formed in each of the four sides of the side wall of the inner tube 10, and the four strip-shaped openings 120 divide the side wall of the open end of the inner tube 10 into two U-shaped side wall deformation portions, and each side wall deformation portion has two sides each comprising a corner 170, and each corner 170 comprises one side edge, as shown in Figure 4 Of course, more than one strip-shaped opening 120 can be formed in any one of the four sides of the inner tube 10, and the open end of the inner tube 10 can also be divided into four corners 170.

[0038] The tensioning component is a screw rod 130, the matching assembly comprises a first elastic tensioning piece 140 and a second elastic tensioning piece 150 fixed respectively on both sides of the side wall of the open end 11, the screw rod 130 is movably connected along the axial direction of the screw rod 130 between the first elastic tensioning piece 140 and the second elastic tensioning piece 150, and at least one of the first elastic tensioning piece 140 and the second elastic tensioning piece 150 is threadedly connected with the screw rod 130. For example, the first elastic tensioning piece 140 and the screw rod 130 are abutted or fixed together, and the second elastic tensioning piece 150 is threadedly connected with the screw rod 130. Alternatively, the second elastic tensioning piece 150 and the screw rod 130 are abutted or fixed together, and the first elastic tensioning piece 140 is threadedly connected with the screw rod 130. When the screw rod 130 is rotated, the portions of the first elastic tensioning piece 140 and the second elastic tensioning piece 150 respectively in contact with the screw rod 130 move away from or close to each other.

[0039] The two ends of the first elastic tensioning piece 140 are connected respectively between two corners 170 of the first side wall deformation part, and the two ends of the second elastic tensioning piece 150 are connected respectively between two corners 170 of the second side wall deformation part. In the embodiment, as shown in Figure 3 and 4 the two ends of the first elastic tensioning piece 140 are connected respectively on two adjacent corners 170 of the four corners 170, and the two ends of the second elastic tensioning piece 150 are connected respectively on the other two adjacent corners 170 of the four corners 170. In order to increase the friction force between the inner tube 10 and the outer tube 20, wear-resistant pieces for frictionally contacting the inner wall of the outer tube 20 are arranged respectively on the four corners 170. The wear-resistant pieces can be rubber blocks or rubber sleeves.

[0040] The first elastic tensioning piece 140 comprises first connecting segments 141 located on both sides and connected respectively with two adjacent corners 170, and a first elastic deformation segment 142 connected between the first connecting segments 141 on both sides; and the second elastic tensioning piece 150 comprises second connecting segments 151 located on both sides and connected respectively with the other two adjacent corners 170, and a second elastic deformation segment 152 connected between the second connecting segments 151 on both sides. In the embodiment, the first elastic deformation segment 142 and the second elastic deformation segment 152 are oppositely arranged and respectively arched inwardly, so that the first elastic tensioning piece 140 and the second elastic tensioning piece 150 have a shape of “M” in the embodiment. The first elastic deformation segment 142 and the second elastic deformation segment 152 are both arc-shaped.

[0041] In order to enhance the elastic force and service life of the first elastic tensioning piece 140 and the second elastic tensioning piece 150, the first elastic tensioning piece 140 and the second elastic tensioning piece 150 can be integrally bent from a metal elastic sheet. The connection between the first connecting segments 141 and the second connecting segments 151 and the inner wall of the inner tube 10 can be achieved by welding, clamping or bolted connection.

[0042] In the present embodiment, the first end of the screw 130 is screwed through the arched top of the first elastically deformed section 142 of the first elastic tensioning member 140, and the second end of the screw 130 abuts against the arched top of the second elastically deformed section 152 of the second elastic tensioning member 150. A female screw member 160 is fixed on the first elastically deformed section 142, and the first end of the screw 130 is screwed through the female screw member 160. An operating portion, specifically a hexagonal hole 131, is formed on the first end of the screw 130. When the first end of the screw 130 is aligned with the operating hole 201 of the outer tube 20, the screw 130 can be operated by inserting a hexagonal wrench into the operating hole 201 of the outer tube 20 corresponding to the hexagonal hole 131 of the screw 130.

[0043] When the screw 130 rotates in the forward direction, the force of the second end of the screw 130 abutting against the second elastic tensioning member 150 increases continuously, and the first elastically deformed section 142 and the second elastically deformed section 152 are relatively tightly abutted against each other. At this time, the curvature of the first elastically deformed section 142 decreases and tends to be straight, so that the two first connecting sections 141 are away from each other and open, and the two corners 170 of the corresponding U-shaped first side wall deformed portion are relatively open and tightly abut against the inner wall of the outer tube 20. Meanwhile, the curvature of the second elastically deformed section 152 also decreases and tends to be straight, so that the two second connecting sections 151 are away from each other and open, and the two corners 170 of the corresponding U-shaped second side wall deformed portion are relatively open and tightly abut against the inner wall of the outer tube 20. Thus, the four corners 170 are all open and tightly abut against the inner wall of the outer tube 20 in the direction perpendicular to the axial direction of the screw 130, and the open end 110 of the inner tube 10 is expanded and tightly fixed with the outer tube 20.

[0044] When the screw 130 rotates in the reverse direction, the force of the second end of the screw 130 abutting against the second elastic tensioning member 150 decreases continuously until the second elastic tensioning member 150 is separated from the screw 130, and the mutual abutting force between the first elastically deformed section 142 and the second elastically deformed section 152 decreases until the abutting force disappears. At this time, the first elastically deformed section 142 tends to bend back to the natural curved state under the elastic force of itself, so that the two first connecting sections 141 are close to each other and reset, and the two corners 170 of the corresponding U-shaped first side wall deformed portion are relatively close to each other and away from the inner wall of the outer tube 20. Meanwhile, the second elastically deformed section 152 tends to bend back to the natural curved state under the elastic force of itself, so that the two second connecting sections 151 are close to each other and reset, and the other two corners 170 of the corresponding U-shaped second side wall deformed portion are relatively close to each other and away from the inner wall of the outer tube 20. Thus, the four corners 170 are all close to each other and away from the inner wall of the outer tube 20 in the direction perpendicular to the axial direction of the screw 130, and the inner tube 10 and the outer tube 20 are separated and can slide relatively along the length direction to adjust the length of the inner tube 10 and the outer tube 20.

[0045] In this embodiment, in order to facilitate the positioning when adjusting the telescopic position of the inner tube, the inner tube 10 is further provided with an elastic positioning member, which comprises a pin shaft 190 and a spring 200. The spring 200 and the pin shaft 190 are installed on a guide seat fixed in the inner tube 10. A through hole is formed in the side wall of the inner tube 10. One end of the pin shaft 190 has a positioning protrusion 191 movably arranged in the through hole of the inner tube 10 and protruding outward. A positioning hole is formed in the side wall of the outer tube 20 and matched with the positioning protrusion 191.

[0046] The locking mechanism further comprises a housing 210 sleeved on the opening of the outer tube 20. A positioning auxiliary hole 211 is formed in the housing 210 and matched with the positioning protrusion 191. An operation auxiliary hole is formed in the housing 210 and matched with the operation hole 201 of the outer tube 20. The housing 210 is further provided with a button 213 for pressing the driving positioning protrusion 191 to retract inward.

[0047] When operating the inner tube 10 and the outer tube 20, first, the inner tube 10 and the outer tube 20 are adjusted to a proper length, and the positioning protrusion 191 of the pin shaft 190 is popped out of the inner tube 10 and clamped into the positioning auxiliary hole 211. Then, a hexagonal wrench is sequentially inserted into the operation auxiliary hole of the housing 210, the operation hole 201 of the outer tube 20 and the operation hole 101 of the inner tube 10. When the screw rod 130 is tightened, the force of the screw rod 130 against the second elastic tensioning member 150 becomes larger, and the first elastic tensioning member 140 and the second elastic tensioning member 150 both tend to be straight, so that the four corners 170 of the open end of the inner tube 10 are expanded outward, thereby tightly fixing the inner tube 10 and the outer tube 20 together.

[0048] When operating the inner tube 10 and the outer tube 20, first, the inner tube 10 and the outer tube 20 are adjusted to a proper length, and the positioning protrusion 191 of the pin shaft 190 is popped out of the inner tube 10 and clamped into the positioning auxiliary hole 211. Then, a hexagonal wrench is sequentially inserted into the operation auxiliary hole of the housing 210, the operation hole 201 of the outer tube 20 and the operation hole 101 of the inner tube 10. When the screw rod 130 is tightened, the force of the screw rod 130 against the second elastic tensioning member 150 becomes larger, and the first elastic tensioning member 140 and the second elastic tensioning member 150 both tend to be straight, so that the four corners 170 of the open end of the inner tube 10 are expanded outward, thereby tightly fixing the inner tube 10 and the outer tube 20 together.

[0049] A plurality of positioning holes and a plurality of operation holes 201 can be arranged in the length direction of the outer tube 20, for adapting to the positioning of the inner tube 10 and the outer tube 20 in a plurality of different telescopic lengths. When transporting, the inner tube 10 and the outer tube 20 can be telescoped to the shortest length, or disassembled to reduce the packaging length.

[0050] The diameter of the screw rod 130 should be larger than the diameter of the operation hole 101 on the inner tube 10 to avoid the screw rod 130 from coming out of the operation hole 101. Meanwhile, in order to avoid misoperation, the end cover 214 is arranged on the shell 210 to block the operation hole 201.

[0051] After the telescopic stand 100 of the embodiment is extended to the longest length, the inner tube 10 and the outer tube 20 are positioned by the elastic positioning members (the pin shaft 190 and the spring 200), and then the opening end 110 of the inner tube 10 is expanded outward by rotating the screw rod 130 through a tool penetrating into the locking mechanism, and the opening end 110 of the inner tube 10 is expanded to abut against the outer tube 20, so that the inner tube 10 and the outer tube 20 are tightly fixed together, the structure of the telescopic stand 100 is more stable, the bearing capacity is larger, and the telescopic stand can have more stable supporting effect. In use, the telescopic stand 100 can be that the outer tube 20 is supported on the ground and the inner tube 10 is located above, or the inner tube 10 is supported on the ground and the outer tube 20 is located above.

[0052] Embodiment Two

[0053] The telescopic stand of the embodiment has basically the same structure as that of Embodiment One, and the difference lies in that the two ends of the screw rod 130 are respectively threadedly connected with the first elastic tensioning member 140 and the second elastic tensioning member 150, the first elastic tensioning member 140 and the second elastic tensioning member 150 are respectively provided with an inner threaded member 160, and the screw thread lines on the two ends of the screw rod 130 have opposite screw directions, as shown in Figure 5 When the screw rod 130 is rotated in the forward direction, the first elastic deformation section 142 and the second elastic deformation section 152 are abutted against each other to make the four corners 170 expand outward along the direction perpendicular to the axial direction of the screw rod 130 to tightly abut against the inner wall of the outer tube 20, so that the opening end 110 of the inner tube 10 is expanded and the inner tube 10 and the outer tube 20 are fixed together. When the screw rod 130 is rotated in the reverse direction, the abutting force between the first elastic deformation section 142 and the second elastic deformation section 152 is reduced, the four corners 170 are contracted inward along the direction perpendicular to the axial direction of the screw rod 130 to be separated from the inner wall of the outer tube 20, so that the inner tube 10 and the outer tube 20 can slide relative to each other along the length direction to adjust the telescopic length of the two.

[0054] Embodiment Three

[0055] As Figure 6 and 7As shown, the embodiment provides a tent, which comprises a crossbeam 30, a canopy frame 40 and a tent cloth, and further comprises the telescopic column 100 in the first embodiment or the second embodiment, wherein the number of telescopic columns 100 is four, and the crossbeam 30 is connected between two telescopic columns 100. Two telescopic columns 100 are connected by a crossbeam 30, and four telescopic columns 100 are sequentially connected by four crossbeams 30 to form a cubic frame. The canopy frame 40 is fixed on the cubic frame formed by the telescopic columns 100 and the crossbeams 30, and the canopy frame 40 comprises a top connecting piece 410 and a plurality of top poles 50 connected to the top connecting piece 410. Specifically, in the embodiment, a plurality of connecting interfaces 411 are arranged on the top connecting piece 410, the upper end of each top pole 50 is connected to a corresponding connecting interface 411, and each top pole 50 extends obliquely downward; the lower part of a part of the plurality of top poles 50 is connected to the upper end of the telescopic column 100, and the lower part of the other top poles 50 is connected to the crossbeam 30. In the embodiment, the number of top poles 50 is eight, wherein four top poles 50 are respectively connected to the top connecting piece 410 and the upper end of a corresponding telescopic column 100, and the other four top poles 50 are respectively connected to the top connecting piece 410 and the middle of a corresponding crossbeam 30.

[0056] Each crossbeam 30 and the telescopic column 100 are further provided with a diagonal brace 60. Two crossbeams 30 connected to the same telescopic column 100 are perpendicular to each other, and a diagonal brace 60 is further connected between the two crossbeams 30. The two diagonal braces 60 on the same telescopic column 100 and the diagonal brace 60 between the two crossbeams 30 on the telescopic column 100 form a triangle. The diagonal brace 60 can strengthen the strength of the cubic frame and make the overall structure more stable. In order to facilitate packaging and transportation, the top pole 60 is also composed of a plurality of links connected in sequence.

The assembly process is very convenient. Since each telescopic column 100 is telescopic, the crossbeam 30 and the top pole 50 can be disassembled into shorter parts, which greatly reduces the packaging volume and facilitates transportation and storage.
