Description

Technical Field

[0001] The invention belongs to the technical field of inflatable tents, in particular to an inflatable automatic tent support rod locking device. Background Art

[0002] Inflatable tents are a type of tent. The frame is designed based on the principles of structural mechanics. The air bag is inflated by the characteristics of gas pressure to form a column with a certain rigidity. After organic combination, the frame of the tent is supported. Inflatable tents are also called air-tight tents. Once inflated, they can be used continuously.

[0003] A patent application with publication number CN215760842U discloses an inflatable tent with an automatic inflation device, including an inflatable tent, on which a support structure is arranged, and the support structure includes: a top plate, a vertical rod, a support part, a connecting part and an inflation part, the top plate is arranged at the upper end of the inflatable tent, the vertical rod is connected to the lower end of the inflatable tent through the connecting part, the support part is arranged between the top plate and the vertical rod, and the inflation part is arranged on the top plate. The utility model adopts and has a support structure on all sides, which can effectively improve the firmness of the tent body and reduce the problem of collapse of the tent body due to unstable support during use.

[0004] The above prior art has the following technical problems when used: The above-mentioned prior art requires the user to wait for the tent to be fully inflated before connecting and fixing the support poles, which will cause problems with installation efficiency. At the same time, the two ends of the support poles need to be connected correspondingly during the installation process. Since the height of the tent body is relatively high, it is more difficult for the user to connect the higher ends of the support poles. When disassembling the support poles, the staff are required to perform the disassembly operations one by one, which will reduce the disassembly and storage efficiency and may also cause fatigue of the staff. In addition, the support poles are designed to be separated from the tent body. Therefore, when the support poles are disassembled for storage, they may be lost, thereby affecting the overall support effect of the tent.

[0005] The above-mentioned prior art uses the cone head and the ground to measure the height. When strong wind or other external pressure occurs, the cone head may be tilted, thereby affecting the overall supporting effect of the tent body.

[0006] The above-mentioned prior art requires manual adjustment of the rotation angle of the horizontal frame and fixing and limiting the position by screws when in use, which makes the installation process cumbersome and increases the installation intensity of the workers.

At the same time, the rotating frame is driven to rotate by the first pneumatic mechanism during the inflation process, so that the rotating frame drives the second magnetic block to rotate to a suitable position and adsorbs the magnetic ball into the limiting hole, thereby completing the automatic fixing operation of the support pole, eliminating the need for manual installation operations by the staff, and reducing the installation intensity of the staff.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0024] like Figures 1 to 6 As shown, an inflatable automatic tent support pole locking device according to an embodiment of the present invention comprises a horizontal plate 2, a fixing frame 7, and a tent body 1 and an air pump 6 arranged on the lower surface of the horizontal plate 2, characterized in that: the four corners of the horizontal plate 2 are rotatably connected with support rods 3, the interior of the support rod 3 is rotatably connected with a rotating frame 34, both ends of the rotating frame 34 are fixedly connected with second magnetic blocks 36, both sides of the support rod 3 are provided with limiting holes 38, the side wall surface of the tent body 1 is fixedly connected with a fixing block 5, the interior of the fixing block 5 is provided with a positioning groove 51, and the shape of the positioning groove 51 matches the support rod 3, the interior of the fixing block 5 is slidably connected with a magnetic ball 53, and the size of the magnetic ball 53 matches the size of the limiting hole 38; A second pneumatic mechanism is provided inside the transverse plate 2, and the second pneumatic mechanism includes a second air cylinder 4 fixedly connected inside the transverse plate 2, an air inlet hole 43 is provided on the circumferential surface of the second air cylinder 4, a second piston 41 is slidably connected inside the second air cylinder 4, one end of the second piston 41 is rotatably connected to a connecting rod 42, and the other end of the connecting rod 42 is rotatably connected to the support rod 3; A first pneumatic mechanism is provided inside the support rod 3, and the first pneumatic mechanism is fixedly connected to the first air cylinder 37 inside the support rod 3, and the first piston 31 is slidably connected inside the first air cylinder 37, and a hose 33 is fixedly connected between the circumferential surface of the first air cylinder 37 and the inside of the cross plate 2, and one end of the first piston 31 is rotatably connected to a push rod 39, and the support rod 3 is rotatably connected to a rotating frame 34 inside, and one side of the rotating frame 34 is rotatably connected to the other end of the push rod 39.

[0025] Specifically, before use, the fixing frame 7 is fixed inside the soil, and the tent body 1 and the fixing frame 7 are connected. At this time, the pump can be turned on to inflate the cavity of the cross plate 2. The connection structure between the cross plate 2 and the tent body 1 is a prior art. For details, please refer to the inflation process between the inflatable tent and the top plate in the publication number CN215760842U. Therefore, when the airflow flows into the interior of the tent body 1 through the cavity and the tent body 1 is inflated, the gas inside the cross plate 2 can enter the interior of the second gas cylinder 4 through the air inlet 43. The gas pressure inside the second gas cylinder 4 pushes the second piston 41 to slide, and the second piston 41 slides downward and drives the connecting rod 42 to rotate. The connecting rod 42 squeezes one end of the support rod 3 and makes the support rod 3 under the cross plate 2. The tent body 1 is rotated from storage. Since the tent body 1 has not been formed at this time, when the support rod 3 originally stored under the cross plate 2 rotates, due to the long length of the support rod 3, the height of the tent body 1 does not meet the requirement. Therefore, one end of the support rod 3 rotates to the side of the fixed block 5, and the other end of the support rod 3 is located below the side of the fixed block 5. As the gas inside the tent body 1 increases, the position of the support rod 3 rises with the tent body 1 and the cross plate 2. After the tent body 1 is inflated and formed, the support rod 3 can completely enter the positioning groove 51 inside the fixed block 5 to support the tent body 1. After the tent body 1 is inflated, the support rod 3 can be automatically driven to move to the inside of the positioning groove 51 to reduce the workload of workers for manual installation and positioning. When air is introduced into the cavity inside the cross plate 2 during the inflation process of the tent body 1, the gas will also enter the first air cylinder 37 through the hose 33. At the same time, as the gas inside the first air cylinder 37 continues to enter, the gas will push the first piston 31 to slide inside the first air cylinder 37. The movement of the first piston 31 will drive the push rod 39 to rotate. The other end of the push rod 39 will then drive the rotating frame 34 to rotate, so that the rotating frame 34 can drive the second magnetic block 36 to rotate to a specified angle, so that the support rod 3 enters the positioning groove 51 inside the fixed block 5, and the second magnetic block 36 can be used to magnetically contact the second magnetic block 36. The ball 53 performs an adsorption operation, thereby driving the rotating frame 34 to rotate to a specified angle when the tent body 1 is gas-filled to facilitate the subsequent adsorption of the magnetic ball 53 to fix the support rod 3, which solves the problem in the prior art that the rotating frame 34 can be automatically driven to rotate according to the air pressure conditions inside the cross plate 2 to complete the conversion of the second magnetic block 36, and when the support rod 3 moves to the positioning groove 51, the adsorbed magnetic ball 53 moves into the inside of the limiting hole 38, thereby automatically fixing the support rod 3 without the need for manual installation by the user. The problem of low installation efficiency caused by manual fixation of the support rod 3 is solved.

[0026] like Figure 4-6 As shown, in this embodiment, a first spring 32 is fixedly connected between one end of the first piston 31 and the interior of the first air cylinder 37, and the hose 33 is made of a telescopic bellows material.

[0027] Specifically, when the tent body 1 is not in use and is vented, the gas inside the first air cylinder 37 decreases. At this time, the first spring 32 drives the first piston 31 to move, so that the rotating frame 34 is reset, and the magnetic ball 53 is reset to the inside of the fixed block 5 through the third spring 52. The fixing effect on the support rod 3 can be automatically released when the tent is vented and stored.

[0028] like Figure 2-3 As shown, in this embodiment, the second air cylinder 4 is tilted, and a second spring 44 is fixedly connected between the inside of the second piston 41 and one end of the first piston 31 .

[0029] Specifically, when the tent body 1 needs to be stored after use, the gas pressure inside the second gas cylinder 4 is less than the force of the second spring 44, so that the second spring 44 drives the second piston 41 to reset, and finally drives the support rod 3 to be stored under the horizontal plate 2, which not only saves space but also avoids the problem of loss due to separate storage.

[0030] like Figure 5 As shown, the magnetism of the magnetic ball 53 and the second magnetic block 36 in this embodiment is attracted to each other, and a third spring 52 is fixedly connected between the circumferential surface of the magnetic ball 53 and the inside of the fixed block 5 .

[0031] Specifically, the third spring 52 can quickly drive the magnetic ball 53 to reset when the magnetic ball 53 and the second magnetic block 36 are released from adsorption, so as to achieve the purpose of quickly releasing the limit of the support rod 3.

[0032] like Figure 7-8 As shown, one end of the tent body 1 described in this embodiment is fixedly connected to a limiting block 8, one end of the limiting block 8 is fixedly connected to a positioning rod 81, the circumferential surface of the positioning rod 81 is provided with a slot 82, a positioning hole is provided inside the fixing frame 7, and the size of the positioning hole matches the size of the positioning rod 81, the inner wall of the fixing frame 7 is slidably connected to a limiting rod 9, the size of the limiting rod 9 matches the size of the slot 82, and a fourth spring 91 is fixedly connected between the circumferential surface of the limiting rod 9 and the inner wall of the fixing frame 7.

[0033] Specifically, before the tent body 1 is used, the positioning rod 81 on the limiting block 8 on the side of the tent body 1 is aligned with the internal positioning hole of the fixing frame 7 that has been fixed to the ground. As the positioning rod 81 slides into the fixing frame 7 and squeezes the limiting rod 9, the limiting rod 9 is squeezed and slides toward the outside of the fixing frame 7. At the same time, when the positioning rod 81 completely enters the fixing frame 7, the position of the limiting rod 9 corresponds to the position of the slot 82. Therefore, under the action of the fourth spring 91, the limiting rod 9 can be driven to enter the slot 82, thereby completing the limiting operation of the positioning rod 81, and the fixing operation of the bottom of the tent body 1 can be realized.

[0034] like Figure 7 and Fig. 9 As shown, in this embodiment, a protrusion is fixedly connected to the lower surface of the fixed block 5, and a cross frame 102 is rotatably connected inside the fixed frame 7. One end of the cross frame 102 is fixedly connected to a connecting block 103, and a groove is provided inside the connecting block 103, and the size of the groove matches the size of the protrusion. The fixed frame 7 is rotatably connected to the first connecting rod 10, and the other end of the first connecting rod 10 is rotatably connected to the second connecting rod 101, and the other end of the second connecting rod 101 is rotatably connected to one end of the cross frame 102, and a fifth spring 104 is fixedly connected between the rotating end of the first connecting rod 10 and the inner wall of the fixed frame 7.

[0035] Specifically, when the positioning rod 81 enters the interior of the fixing frame 7 through the positioning hole, the positioning rod 81 will squeeze the first connecting rod 10 as it continues to enter, so that the first connecting rod 10 is squeezed and rotates, so the first connecting rod 10 will drive the second connecting rod 101 to rotate, and the other end of the second connecting rod 101 drives the cross frame 102 to rotate, and the cross frame 102 rotates from the inside of the fixing frame 7 and drives the connecting block 103 to rotate ninety degrees. At this time, the user can connect the positions of the protrusions and the grooves correspondingly, so that the side surface of the tent body 1 can be fixed and the position of the fixing block 5 can be limited, which is convenient for the subsequent support rod 3 to rotate into the interior of the fixing block 5 to complete the limiting operation, thereby achieving the reconciliation. The tent body 1 plays a supporting role, and can also automatically adjust the cross frame 102 to rotate and lock it at a ninety-degree position according to the insertion of the positioning rod 81 and the premise that the position of the positioning rod 81 is fixed, without the need for manual adjustment by the staff again. When the cross frame 102 needs to be stored, the limit rod 9 is driven to disengage from the interior of the slot 82, so that the fifth spring 104 drives the first connecting rod 10 to reset, so that the second connecting rod 101 can drive the cross frame 102 to reset to the interior of the fixed frame 7 to reduce the space occupied. At the same time, the first connecting rod 10 pushes the positioning rod 81, which can achieve the purpose of automatically escaping from the interior of the fixed frame 7 after the positioning rod 81 is released from the limit, thereby reducing the work of disassembly by the staff. Embodiment 2

[0036] like Figure 7 , Figure 10-12 As shown, compared with Example 1, another embodiment of the present invention is: the fixed frame 7 is internally slidably connected to the first cone head 11, the first cone head 11 is internally slidably connected to the moving rod 114, one end of the moving rod 114 is fixedly connected to the moving rod 114, one end of the moving rod 114 is fixedly connected to the extrusion head 115, one side of the extrusion head 115 is set to an inclined type, the first cone head 11 is internally fixedly connected to the inclined plate 116, the inclined plate 116 is internally slidably connected to the second cone head 118, one end of the second cone head 118 is set to an arc, and the arc-shaped end face of the second cone head 118 fits the inclined side face of the extrusion head 115.

[0037] Specifically, before use, the fixing frame 7 and the ground need to be fixed and supported. At this time, after the fixing frame 7 is driven to the specified position, the user presses the pedal 1113 and drives the first cone head 11 to slide out from the inside of the fixing frame 7 and penetrate deep into the soil to complete the initial fixation of the fixing frame 7. At this time, the moving rod 114 is adjusted so that the moving rod 114 drives the extrusion head 115 to descend. Since the side of the extrusion head 115 is inclined, when the extrusion head 115 descends, the other end of the second cone head 118 is squeezed, so the second cone head 118 slides out from the inside of the first cone head 11 and penetrates deep into the soil in an inclined motion, which can increase the contact area with the soil, thereby improving the tensile strength and providing greater supporting force, avoiding the fixing frame 7 from swaying or tilting under strong winds or other external pressures, thereby causing the final support rod 3 to be misplaced to affect the overall supporting effect of the tent body 1. At the same time, different lengths can be extended and retracted according to different soil types to perform rooting operations.

[0038] like Fig.12 As shown, in this embodiment, the circumferential surface of the second cone head 118 is fixedly connected to the slide rod 119, the interior of the inclined plate 116 is provided with an inclined groove 117, and the interior of the inclined groove 117 is slidably connected to the circumferential surface of the slide rod 119, and a sixth spring 1110 is fixedly connected between the circumferential surface of the slide rod 119 and one side of the inclined plate 116.

[0039] Specifically, the second cone head 118 slides outward from the inside of the first cone head 11, and the slide rod 119 arranged on the circumferential surface of the second cone head 118 can be limited and stably slid in the inclined groove 117 opened in the inclined plate 116. At the same time, when the extrusion head 115 moves upward to reset, the sixth spring 1110 drives the slide rod 119 to reset, thereby driving the second cone head 118 to be quickly retracted into the inside of the first cone head 11. At the same time, the sixth spring 1110 can keep the arc-shaped end face of the second cone head 118 and the side wall of the extrusion head 115 in close contact.

[0040] like Figure 7 and Fig.10 As shown, in this embodiment, the first cone head 11 is internally rotatably connected to a screw rod 111, and the circumferential surface of the screw rod 111 is threadedly connected to the internal part of the movable rod 114, a first slide groove 112 is provided inside the screw rod 111, and a movable rod 113 is slidably connected inside the first slide groove 112, one end of the movable rod 113 is fixedly connected to a first bevel gear 1111, and the inner wall of the fixed frame 7 is rotatably connected to a second bevel gear 1112, and the second bevel gear 1112 and the first bevel gear 1111 are meshed with each other.

[0041] Specifically, when the first cone head 11 moves downward and enters deep into the soil, the first cone head 11 drives the screw rod 111 to descend, and the screw rod 111 slides downward on the surface of the movable rod 113. When it is necessary to drive the movable rod 114 to move, the second bevel gear 1112 and the first bevel gear 1111 can be rotated to engage, and the first bevel gear 1111 drives the movable rod 113 to rotate, and the movable rod 113 then drives the screw rod 111 to rotate synchronously through the first slide groove 112, so that the first cone head 11 can drive the screw rod 111 to move to different positions, and the screw rod 111 can also be driven to rotate by the second bevel gear 1112.

[0042] like Figure 7 As shown, in this embodiment, a second slide groove 1114 is provided on the surface of the fixing frame 7, and a pedal 1113 is slidably connected inside the second slide groove 1114 . One end of the pedal 1113 is fixedly connected to the circumferential surface of the first cone head 11 .

[0043] Specifically, the user presses down the pedal 1113 , and the pedal 1113 stably descends and slides inside the second slide groove 1114 , and at the same time drives the first cone head 11 to stably penetrate deep into the soil, thereby completing the fixing operation of the fixing frame 7 .

[0044] Working principle: Before use, the fixing frame 7 and the ground need to be fixed and supported. At this time, after the fixing frame 7 is driven to the specified position, the user presses the pedal 1113 and drives the first cone head 11 to slide out from the inside of the fixing frame 7 and penetrate deep into the soil to complete the initial fixation of the fixing frame 7. At this time, the moving rod 114 is adjusted to make the moving rod 114 drive the extrusion head 115 to descend. Since the side of the extrusion head 115 is inclined, when the extrusion head 115 descends, the other end of the second cone head 118 is squeezed, so the second cone head 118 slides out from the inside of the first cone head 11; The positioning rod 81 on the limiting block 8 on the side of the tent body 1 is aligned with the internal positioning hole of the fixing frame 7 that has been fixed to the ground. As the positioning rod 81 slides into the fixing frame 7 and squeezes the limiting rod 9, the limiting rod 9 is squeezed and slides toward the outside of the fixing frame 7. At the same time, when the positioning rod 81 completely enters the fixing frame 7, the position of the limiting rod 9 corresponds to the position of the slot 82. Therefore, under the action of the fourth spring 91, the limiting rod 9 can be driven to enter the slot 82, thereby completing the limiting operation of the positioning rod 81. When the positioning rod 81 When entering the interior of the fixing frame 7 through the positioning hole, the positioning rod 81 will squeeze the first connecting rod 10 as it continues to enter, so that the first connecting rod 10 is squeezed and rotates, so the first connecting rod 10 drives the second connecting rod 101 to rotate, and the other end of the second connecting rod 101 drives the cross frame 102 to rotate, and the cross frame 102 rotates from the inside of the fixing frame 7 and drives the connecting block 103 to rotate ninety degrees. At this time, the user can connect the positions of the protrusions and the grooves correspondingly, so that the side surface of the tent body 1 can be fixed and the position of the fixing block 5 can be limited. When the horizontal plate 2 is inhaled, the gas inside the horizontal plate 2 can enter the second gas cylinder 4 through the gas inlet hole 43, and the gas pressure inside the second gas cylinder 4 pushes the second piston 41 to slide, and the second piston 41 slides downward and drives the connecting rod 42 to rotate, and the connecting rod 42 squeezes one end of the support rod 3, and makes the support rod 3 rotate from being stored under the horizontal plate 2. As the gas inside the tent body 1 increases later, the support rod 3 can completely enter the positioning groove 51 inside the fixing block 5 to support the tent body 1. When the cavity inside the horizontal plate 2 is inhaled, the gas will enter the first gas cylinder through the hose 33 37, and as the gas inside the first gas cylinder 37 continues to enter, the gas will push the first piston 31 to slide inside the first gas cylinder 37, and the first piston 31 will drive the push rod 39 to rotate while moving, and the other end of the push rod 39 will push the rotating frame 34 to rotate, so that the rotating frame 34 can drive the second magnetic block 36 to rotate to a specified angle, and the second magnetic block 36 can adsorb the magnetic ball 53. Due to the magnetic attraction between the second magnetic block 36 and the magnetic ball 53, the magnetic ball 53 will slide and be adsorbed into the internal limiting hole 38 of the support rod 3, and the fixing operation of the support rod 3 can be completed at this time; When the tent body 1 is not in use and is being vented, the gas inside the first gas cylinder 37 is reduced. At this time, the first spring 32 drives the first piston 31 to move, so that the rotating frame 34 is reset, and the magnetic ball 53 is reset to the inside of the fixed block 5 through the third spring 52, which can automatically release the fixing effect on the support rod 3. At the same time, the gas pressure inside the second gas cylinder 4 is less than the force of the second spring 44, so that the second spring 44 drives the second piston 41 to reset, and finally the support rod 3 can be stored under the horizontal plate 2.
