[0002] As a daily necessity temporarily used to block wind and rain, tents are extremely common in daily life. Currently, tents on the market are generally divided into telescopic tents and fixed tents according to their structural types.

[0003] Existing telescopic tents use a link-type telescopic support frame to support the canopy. Restricted by the structure of the link-type telescopic support frame, the canopy cannot use hard materials and can only use soft materials such as cloth. However, cloth has problems such as being not durable, having a poor shielding effect, and being prone to catching fire.

[0004] Existing fixed tents use a fixed support frame to support the canopy. Since the fixed support frame has a fixed structure, the canopy of the fixed tent can use a tile canopy to achieve shielding through multiple hard material tiles. However, the existing fixed tent has a fixed structure, occupies a large area, and is not flexible to use. Summary of the Invention

Detailed implementation manners

[0034] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope protected by the present invention.

[0035] Embodiment 1:

[0036] The present invention provides a movable push-pull telescopic support frame. Referring to Figures 1 to 7 as shown, the movable push-pull telescopic support frame includes a fixed support frame 1, a telescopic support frame 2 and a guiding and moving mechanism 3.

[0037] The fixed support frame 1 includes a support bottom frame 11 and a support top frame 12. The support top frame 12 is a fixed frame structure and is fixedly arranged on the support bottom frame 11; the telescopic support frame 2 includes a telescopic bottom frame 21 and a telescopic top frame 22. The telescopic top frame 22 is a fixed frame structure and is fixedly arranged on the telescopic bottom frame 21; the telescopic top frame 22 is connected to the support top frame 12 through the guiding and moving mechanism 3. The guiding and moving mechanism 3 can adopt a sleeve sleeved on the top frame, a slider slidably arranged on the top frame, etc.

[0038] When not in use, push the telescopic support frame 2. The telescopic support frame 2 moves relative to the fixed support frame 1 to the retracted position through the guiding and moving mechanism 3. At this time, the telescopic support frame 2 is located inside the fixed support frame 1, occupying a small floor space.

[0039] When in use, pull the telescopic support frame 2. The telescopic support frame 2 moves relative to the fixed support frame 1 to the extended position through the guiding and moving mechanism 3. At this time, the telescopic support frame 2 and the fixed support frame 1 have a large support area. Cooperating with the awning at its top position, it has a good shielding effect.

[0040] In the present invention, the support top frame 12 of the fixed support frame 1 and the telescopic top frame 22 of the telescopic support frame 2 both adopt a fixed frame structure, which can install a rigid awning. Through the guiding and moving mechanism 3, only by pushing and pulling operations, the relative movement of the fixed support frame 1 and the telescopic support frame 2 can be realized, thereby achieving telescoping. Not only is the structure flexible, but also the use is convenient.

[0041] Embodiment 2:

[0042] Embodiment 2 is based on Embodiment 1:

[0043] As Figures 1 to 8 shown, the guiding and moving mechanism 3 includes a guiding member 31 and a moving member 32.

[0044] The guiding member 31 is fixedly arranged on the support bottom frame 11. The guiding member 31 is parallel to the moving direction of the telescopic support frame 2. The guiding member 31 is located at a position close to the support top frame 12. In this way, the space below it can be effectively guaranteed.

[0045] The moving member 32 is arranged on the telescopic top frame 22. The moving member 32 is located on the guiding member 31 and can move relative to the guiding member 31.

[0046] The guiding member 31 and the moving member 32 cooperate with each other, which can effectively limit the moving track of the telescopic support frame 2 relative to the fixed support frame 1, thereby ensuring the stability during the pushing and pulling telescoping process. The moving member 32 and the guiding member 31 can adopt sliding friction or rolling.

[0047] Specifically, the guiding member 31 is set as a guide rail, and the moving member 32 is set as a pulley. A bracket is arranged on the bottom side of the telescopic top frame 22. The pulley is rotatably arranged on the bracket. The pulley is in rolling cooperation with the guide rail. Adopting rolling friction, the friction resistance is small and the moving process is smoother.

[0048] As an optional implementation manner, the movable push-pull telescopic support frame includes a cross-link mechanism 4. The telescopic bottom frame 21 is connected to the support bottom frame 11 through the cross-link mechanism 4.

[0049] In the actual application process, when the telescopic support frame 2 is in the extended position relative to the fixed support frame 1, the cross-linkage mechanism 4 is in the extended state; when the telescopic support frame 2 is in the retracted position relative to the fixed support frame 1, the cross-linkage mechanism 4 is in the retracted state.

[0050] The cross-linkage mechanism 4 can effectively limit the extreme movement position of the telescopic support frame 2, thereby preventing the telescopic support frame 2 from detaching from the fixed support frame 1.

[0051] As an alternative embodiment, the cross-linkage mechanism 4 includes a first link 41, a second link 42, and a hinge member 43.

[0052] The top end of the first link 41 is hinged to the support chassis 11, and the bottom end of the first link 41 is hinged to the first hinge member, and the first hinge member is slidably arranged in the vertical direction on the telescopic chassis 21.

[0053] The top end of the second link 42 is hinged to the telescopic chassis 21, and the bottom end of the second link 42 is hinged to the second hinge member, and the second hinge member is slidably arranged in the vertical direction on the support chassis 11.

[0054] The first hinge member and the second hinge member have the same structure, both being the hinge member 43. The hinge member 43 includes a collar and a hinge shaft integrally provided on the collar, and the collar is slidably sleeved on the support chassis 11 or the first leg 111 of the telescopic chassis 21.

[0055] The first link 41 and the second link 42 are cross-arranged, and the middle position of the first link 41 is hinged to the middle position of the second link 42.

[0056] The first link 41, the second link 42, and the hinge member 43 cooperate with each other, and the limiting effect is remarkable on the premise of ensuring the smooth progress of the telescopic movement.

[0057] As an alternative embodiment, the number of telescopic support frames 2 is set to be multiple, and the fixed support frame 1 and all telescopic support frames 2 are arranged in sequence; two adjacent telescopic top frames 22 are connected by a guiding movement mechanism 3; two adjacent telescopic chassis 21 are connected by a cross-linkage mechanism 4.

[0058] The fixed support frame 1 and all telescopic support frames 2 form a nested telescopic structure. No matter how many telescopic support frames 2 the movable push-pull telescopic support frame has, it has a small floor area.

[0059] As an alternative embodiment, two adjacent guide members 31 along the moving direction of the telescopic support frame 2 are connected by a connecting member 33; one of the two guide members 31 is fixedly connected to the connecting member 33, and the other guide member 31 is movably connected to the connecting member 33; specifically, the connecting member 33 is C-shaped.

[0060] In this way, without affecting the moving effect of the telescopic support frame 2, it has a connecting function and a guiding function, making the entire pushing and pulling movement process smoother.

[0061] Taking the three - nested telescopic structure as an example, the movable push - pull telescopic support frame has a fixed support frame 1, two telescopic support frames 2, two guiding and moving mechanisms 3 and two cross - link mechanisms 4. Among them, the two telescopic support frames 2 are respectively the first telescopic support frame and the second telescopic support member in the direction away from the fixed support frame 1. The two guiding and moving mechanisms 3 are respectively the first guiding and moving mechanism and the second guiding and moving mechanism. The first guiding and moving mechanism connects the fixed support frame 1 and the first telescopic support frame. The first guiding and moving mechanism includes a first guide member, a first moving member and a connecting member 33. The second guiding and moving mechanism connects the first telescopic support frame and the second telescopic support frame. The second guiding and moving mechanism includes a second guide member and a second moving member. The first guide member is fixedly arranged on the support bottom frame 11 and is in sliding connection with the connecting member 33. The second guide member is fixedly arranged on the telescopic bottom frame of the first telescopic support frame and is fixedly connected with the connecting member 33. In this way, during the movement of the first telescopic support frame, the second guide member and the connecting member 33 move synchronously relative to the first guide member.

[0062] As an optional implementation manner, the movable push - pull telescopic support frame includes a moving wheel mechanism 5. The moving wheel mechanism 5 is arranged at the bottom of both the support bottom frame 11 and the telescopic bottom frame 21.

[0063] The moving wheel mechanism 5 includes a moving wheel 51, and the moving wheel 51 can be set as a universal locking wheel.

[0064] As an optional implementation manner, both the support bottom frame 11 and the telescopic bottom frame 21 include plug - in legs. The plug - in legs include a first leg 111 and a second leg 112. A sliding cavity sized to fit the second leg 112 is axially opened at the top of the first leg 111, and the second leg 112 is inserted into the sliding cavity. The second leg 112 of the support bottom frame 11 is fixedly connected with the support top frame 12. The second leg 112 of the telescopic bottom frame 21 is fixedly connected with the telescopic top frame. The plug - in legs adopt a plug - in structure, which is convenient for insertion and installation.

[0065] Specifically, both the support top frame 12 and the telescopic top frame 22 are set as a cross - shaped frame structure. The support top frame 12 has four of the plug - in feet, which are respectively located at the four corners. The telescopic top frame 22 has two of the plug - in feet, which are arranged at the two corners on the side of the telescopic top frame 22 away from the fixed support frame 1.

The first rigid tile awning is fixedly arranged on the support top frame 12 by bolts, and the second rigid tile awning is fixedly arranged on the telescopic top frame 22 by bolts.

[0070] Both the first rigid tile awning and the second rigid tile awning include a plurality of fixed tiles. The fixed tiles are made of rigid materials. Specifically, color steel tiles, resin tiles, rust-proof tiles, aluminum tiles, PVC tiles, etc. can be used.
