Description

Technical Field

[0001] This application relates to the technical field of umbrella support frames, and specifically to an umbrella support frame. Background Technology

[0002] Nowadays, many shops need to set up a support umbrella outdoors to shield themselves from the sun or rain when people go out for a spring outing. However, the placement of the umbrella often needs to be moved to better protect them from the wind and rain. Since the umbrella itself is quite large, it is very inconvenient to move it manually. Summary of the Invention

[0003] (a) Technical problems to be solved In view of this, this application provides an umbrella support frame with a simple structure and more convenient movement.

[0004] (II) Technical Solution To solve the aforementioned technical problem, this utility model provides an umbrella support frame, comprising: The housing assembly comprises a housing component, a locking structure, and a moving frame. The lower end of the housing component is provided with a limiting member, which has an inclined sliding surface and a limiting groove. A pulley is connected to the lower end face of the housing component. The housing component is provided with the locking structure. The moving frame is connected to the housing component and is provided with rollers. The locking structure unlocks, driving the motion frame to move synchronously, causing the roller to move out of the limiting groove and slide along the inclined sliding surface, thereby releasing the limiting of the roller and the limiting member and driving the motion frame to lift up, so that the lower end surface of the motion frame is higher than the pulley, thereby driving the housing assembly to slide. The locking structure locks the frame, drives the motion frame to move, and drives the roller to lock and limit the movement with the limiting groove of the limiting member. The motion frame is then driven to descend so that the lower end face of the motion frame is lower than the pulley, thereby locking the housing assembly.

[0005] In this solution, a locking structure is used. When the umbrella support frame needs to be moved, the locking structure is unlocked, causing the moving frame to move. The moving frame drives the rollers out of the limiting groove and automatically slides along the inclined sliding surface. This releases the limiting force between the rollers and the limiting components, causing the moving frame to move upward. This makes the lower end of the moving frame higher than the pulley, allowing the pulley to contact the ground and slide the umbrella support frame. When the umbrella support frame needs to be fixed, the locking structure is locked, causing the moving frame to move. The moving frame drives the rollers to slide along the inclined sliding surface into the limiting groove. This locks the limiting force between the rollers and the limiting components, causing the moving frame to move downward. This makes the lower end of the moving frame lower than the pulley, allowing the moving frame to contact the ground and fix the umbrella support frame. The structure is simple and makes moving the umbrella support frame more convenient.

[0006] Preferably, the locking structure includes a foot-locking component and a foot-unlocking component. The foot-locking component includes a locking foot pedal, a first operating piece, and a first support piece. A connecting plate is provided on the housing assembly, and a first mounting post is provided on the connecting plate. The locking foot pedal is provided inside the first mounting post, and a first movable groove is provided on the first mounting post. The first operating piece is provided inside the first movable groove. Stepping down on the locking foot pedal causes the first operating piece to move downward along the first movable groove. The first support piece is connected to the connecting plate, and the first support piece is hinged to the first operating piece. The first operating piece is connected to the motion frame.

[0007] In this solution, by setting a locking foot pedal, stepping on the locking foot pedal causes one end of the first operating piece to move downward along the first movable groove, thereby causing the other end of the first operating piece to move upward, thereby driving the moving frame to move away from the locking foot pedal, thereby causing the roller to lock and limit the limiting groove of the limiting member, thus locking the housing assembly so that it cannot move.

[0008] As a further preferred embodiment, the motion frame is provided with a positioning and fixing piece, one end of the first operating piece is connected to the positioning and fixing piece, and a stop plate is provided on one side of the first operating piece.

[0009] In this solution, by setting a positioning fixing piece, the first operating piece can be better connected to the motion frame to drive the motion frame to move.

[0010] As a further preferred embodiment, the foot-operated unlocking assembly includes a second operating plate and an unlocking foot pedal. A second mounting post is provided on the connecting plate, and an unlocking foot pedal is provided inside the second mounting post. A second movable groove is provided on the second mounting post, and the second operating plate is provided inside the second movable groove. Stepping down on the unlocking foot pedal causes the second operating plate to move downward along the second movable groove.

[0011] In this solution, by setting an unlocking foot pedal, stepping down on the unlocking foot pedal causes one end of the second operating piece to move downward along the second movable groove, thereby causing the other end of the second operating piece to move upward, which in turn drives the first operating piece to move upward, thereby causing the moving frame to move towards the side closer to the unlocking foot pedal, thereby causing the roller to release the limit groove of the limiting member, thus allowing the housing assembly to move.

[0012] As a further preferred embodiment, the second operating piece is provided with a connector that can abut against the abutment. A pad is provided at the lower end of the moving frame, and a connecting rod is provided on the housing assembly.

[0013] In this design, a connecting piece is used to pry up the stop plate, thereby lifting the first operating plate and moving the roller out of the limiting groove. A pad is installed to contact the ground, increasing the lifespan of the motion frame. A connecting rod is used to connect the umbrella.

[0014] Preferably, the motion frame is connected to the housing assembly by a tension spring.

[0015] In this design, the use of a tension spring allows the motion frame to be easily reset after the roller leaves the limiting groove.

[0016] Preferably, the locking structure includes a pedaling motion component and a motion unlocking component. The pedaling motion component includes a pedaling element, a third operating plate, and a second support plate. A connecting plate is provided on the housing assembly, and a third mounting post is provided on the connecting plate. The pedaling element is disposed within the third mounting post, and a third movable groove is provided on the third mounting post. The third operating plate is disposed within the third movable groove. Stepping on the pedaling element downwards causes the third operating plate to move downwards along the third movable groove. The second support plate is connected to the connecting plate, and the second support plate is hinged to the third operating plate. The third operating plate is connected to the motion frame.

[0017] In this solution, by setting a moving foot pedal, stepping on the moving foot pedal causes one end of the third operating plate to move downward along the third movable groove, thereby causing the other end of the third operating plate to move upward, thereby driving the moving frame to move away from the moving foot pedal, thereby causing the roller to lock and limit the limiting groove of the limiting member, thus locking the housing assembly so that it cannot move.

[0018] As a further preferred embodiment, the motion frame is provided with a hinged fixing piece, and one end of the third operating piece is connected to the hinged fixing piece.

[0019] In this solution, by setting a hinged fixing plate, the third operating plate can be better connected to the motion frame to drive the motion frame to move.

[0020] As a further preferred embodiment, the motion unlocking component includes a fixed post with a sliding groove. A connecting sleeve is provided over the fixed post, and hooks are provided on both sides of the connecting sleeve. A connecting post is provided on the connecting sleeve. The connecting post is slidably disposed in the sliding groove and passes through the sliding groove to connect with the motion pedal component. A fixing member and a moving member are provided on the fixed post. The moving member is located at the lower end of the fixing member, and the fixing member can resist the movement of the moving member. Both the fixing member and the moving member can be hooked by the hooks, and the hooks are provided with elastic elements.

[0021] In this solution, a connecting sleeve is installed on the fixed column. When the moving foot pedal is stepped on, the connecting sleeve moves, thereby causing the hook to hook onto the fixed part, which moves the moving frame down and locks the shell assembly. After the moving foot pedal is stepped on again, the hook hooks onto the moving part and rebounds to reset, thereby moving the moving frame up and unlocking the shell assembly so that the umbrella base can be pushed.

[0022] (III) Beneficial Effects Compared with the prior art, the beneficial effects that this specification can achieve include at least the following: By incorporating a locking structure, when the umbrella support frame needs to be moved, the locking structure is unlocked, causing the moving frame to move. The moving frame then moves the rollers out of the limiting groove and automatically slides along the inclined sliding surface. This releases the limiting mechanism between the rollers and the limiting components, driving the moving frame upward. Consequently, the lower end of the moving frame is higher than the pulley, allowing the pulley to contact the ground and slide the umbrella support frame. When the umbrella support frame needs to be fixed, the locking structure is locked, causing the moving frame to move. The moving frame then moves the rollers along the inclined sliding surface into the limiting groove. This locks the limiting mechanism between the rollers and the limiting components, driving the moving frame downward. Consequently, the lower end of the moving frame is lower than the pulley, allowing the moving frame to contact the ground and fix the umbrella support frame. The structure is simple, and moving the umbrella support frame is more convenient. By setting a locking foot pedal, stepping on the locking foot pedal causes one end of the first operating piece to move downward along the first movable groove, thereby causing the other end of the first operating piece to move upward, which in turn drives the moving frame to move away from the locking foot pedal, thereby causing the roller to lock and limit the limiting groove of the limiting member, thus locking the housing assembly so that it cannot move.

[0031] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0032] Example 1: See Figures 1-9 This application provides an umbrella support frame, including a shell assembly 1, a locking structure, and a moving frame 4. The lower end of the shell assembly 1 is provided with a limiting member 11, which is provided with an inclined sliding surface 111 and a limiting groove 112. A pulley 12 is connected to the lower end face of the shell assembly 1. The shell assembly 1 is provided with the locking structure. The moving frame 4 is connected to the shell assembly 1, and a roller 41 is provided on the moving frame 4. When the locking structure is unlocked, the motion frame 4 is driven to move, which in turn drives the roller 41 to move out of the limiting groove 112 and slide along the inclined sliding surface 111, so as to release the limiting of the roller 41 and the limiting member 11 and drive the motion frame 4 to lift up, so that the lower end surface of the motion frame 4 is higher than the pulley 12, thereby driving the housing assembly 1 to slide. The locking structure locks and drives the motion frame 4 to move, thereby driving the roller 41 to lock and limit the limiting groove 112 of the limiting member 11, and driving the motion frame 4 to descend so that the lower end surface of the motion frame 4 is lower than the pulley 12, thereby locking the housing assembly 1.

[0033] Furthermore, as a preferred embodiment, the locking structure includes a foot-locking component 2 and a foot-unlocking component 3. The foot-locking component 2 includes a locking foot pedal 21, a first operating piece 22, and a first support piece 23. A connecting plate 13 is provided on the housing component 1, and a first mounting post 24 is provided on the connecting plate 13. The locking foot pedal 21 is provided inside the first mounting post 24, and a first movable groove 241 is provided on the first mounting post 24. The first operating piece 22 is provided inside the first movable groove 241. Stepping down on the locking foot pedal 21 causes the first operating piece 22 to move downward along the first movable groove 241. The first support piece 23 is connected to the connecting plate 13, and the first support piece 23 is hinged to the first operating piece 22. The first operating piece 22 is connected to the motion frame 4.

[0034] Furthermore, as a preferred embodiment, the motion frame 4 is provided with a positioning and fixing piece 42, and one end of the first operating piece 22 is connected to the positioning and fixing piece 42. A stop plate 25 is provided on one side of the first operating piece 22.

[0035] Furthermore, as a preferred embodiment, the foot-operated unlocking component 3 includes a second operating piece 31 and an unlocking foot pedal 32. A second mounting post 33 is provided on the connecting plate 13, and an unlocking foot pedal is provided inside the second mounting post 33. A second movable groove 331 is provided on the second mounting post 33, and the second operating piece 31 is provided inside the second movable groove 331. Stepping on the unlocking foot pedal downwards causes the second operating piece 31 to move downwards along the second movable groove 331.

[0036] Furthermore, as a preferred embodiment, the second operating piece 31 is provided with a connector 34, which can abut against the abutment plate 25. A pad 43 is provided at the lower end of the moving frame 4. A connecting rod 5 is provided on the housing assembly 1.

[0037] Furthermore, as a preferred embodiment, the motion frame 4 is connected to the housing assembly 1 by a tension spring.

[0038] Specifically, in this embodiment, the shell assembly 1 includes a base plate, four corner connectors, and a cover. Four corner connectors are provided at each of the four corners of the base plate, and a cover is provided at the top of the base plate. The four corner connectors connect the cover to the base plate. A connecting rod 5 is provided on the base plate, extending through the cover. A connecting plate 13 is provided on the base plate, and a foot-operated unlocking assembly 3 and a foot-operated locking assembly 2 are connected to the connecting plate 13. A pulley 12 is provided at the bottom of the base plate. A limiting member 11 is provided at the bottom of the base plate, and a moving frame 4 is connected to the bottom of the base plate via a tension spring. Four pads 43 are provided at the bottom of the moving frame 4. Rollers 41 are provided on the moving frame 4, and the rollers 41 cooperate with the limiting members 11 to raise or lower the moving frame 4, thereby moving or fixing the umbrella support frame. Four limiting members 11 are provided, and four rollers 41 are provided correspondingly. The limiting member 11 is a limiting plate with an inclined sliding surface 111 and a limiting groove 112 on one side. The inclined sliding surface 111 is connected to the limiting groove 112. When the operator steps on the unlocking component 3, it is activated, driving the motion frame 4 to move and simultaneously driving the roller 41 to move out of the limiting groove 112 and slide along the inclined sliding surface 111 until it abuts against the lower end surface of the base plate. This releases the limiting of the roller 41 and the limiting component 11 and drives the motion frame 4 to lift up, so that the lower end surface of the motion frame 4 is higher than the pulley 12, thereby making the pulley 12 contact the ground, which makes it convenient for the operator to push the shell component 1 to slide. When the operator steps on the locking component 2, it drives the motion frame 4 to move and simultaneously drives the roller 41 to slide along the inclined sliding surface 111 into the limiting groove 112. The roller 41 is locked and limited by the limiting groove 112 of the limiting component 11, driving the motion frame 4 to lower down so that the lower end surface of the motion frame 4 is lower than the pulley 12, making the motion frame 4 contact the ground, so that the operator cannot push the shell component 1, thus fixing the position of the umbrella support frame. The housing assembly 1 is also provided with a rotating part of the rotating umbrella seat support frame. The rotating part is existing technology and will not be described in detail here.

[0039] Specifically, in this embodiment, a first mounting post 24 is provided at the upper end of the connecting plate 13, a first motion groove is provided inside the first mounting post 24, a locking foot pedal 21 is provided in the first motion groove and can be moved up and down, a first movable groove 241 communicating with the first motion groove is provided on the first mounting post 24, a first operating piece 22 is provided inside the first movable groove 241, one end of the first operating piece 22 is provided in the first motion groove and located below the locking foot pedal 21, when the locking foot pedal 21 moves downward, it will drive one end of the first operating piece 22 to move downward, a first support piece 23 is provided on the connecting plate 13, the first support piece 23 is hinged to the first operating piece 22, a positioning fixing piece 42 is provided on the upper surface of the motion frame 4, the other end of the first operating piece 22 is connected to the positioning fixing piece 42; a stop plate 25 is provided on the side of the first operating piece 22 near the foot unlocking component 3.

[0040] Specifically, in this embodiment, a second mounting post 33 is provided at the upper end of the connecting plate 13. The second mounting post 33 is located in front of the first mounting post 24, and the upper ends of the two are connected as one piece. A second motion groove is provided inside the second mounting post 33. An unlocking foot pedal is movably provided in the second motion groove. A second movable groove 331 communicating with the second motion groove is provided on the second mounting post 33. A second operating piece 31 is provided inside the second movable groove and located below the unlocking foot pedal. When the unlocking foot pedal moves downward, it will drive one end of the second operating piece 31 to move downward. A connecting piece 34 is provided at the other end of the second operating piece 31. The connecting piece 34 is a screw that passes through the second operating piece 31. A torsion spring and a torsion plate are provided on the second operating piece 31. When the unlocking foot pedal is released, the second operating piece 31 returns to its original position.

[0041] Specifically, in this embodiment, when the locking foot pedal 21 is stepped on and moves downward, one end of the first operating piece 22 moves downward simultaneously, the other end of the first operating piece 22 tilts upward, and the other end of the first support piece 23 also moves downward, thereby reducing the angle between the first operating piece 22 and the first support piece 23. Simultaneously, the moving frame 4 is pushed to move away from the locking foot pedal 21, and the roller 41 is simultaneously driven to slide along the inclined sliding surface 111 into the limiting groove 112. The roller 41 is locked and limited by the limiting groove 112 of the limiting piece 11, and a self-locking is formed by the counter-clamping angle between the first support piece 23 and the first operating piece 22, so that the roller 41 will not drive out of the limiting groove 112. The moving frame 4 is lowered so that the lower end surface of the moving frame 4 is lower than the pulley 12, so that the pad 43 of the moving frame 4 contacts the ground, so that the operator cannot push the shell assembly 1, thus fixing the position of the umbrella support frame.

[0042] Specifically, in this embodiment, when the unlocking foot pedal is pressed and moves downward, one end of the second operating piece 31 moves downward simultaneously, and the other end of the second operating piece 31 tilts upward, so that the connecting piece 34 abuts against the abutment plate 25. Because the connecting piece 34 tilts upward, it lifts the abutment plate 25, so that the roller 41 leaves the limiting groove 112 and moves along the inclined sliding surface 111. Under the action of the tension spring, the moving frame 4 moves towards the side closer to the unlocking foot pedal and moves upward. The movement of the moving frame 4 synchronously drives the roller 41 to move out of the limiting groove 112 and slide along the inclined sliding surface 111 until it abuts against the lower end surface of the base plate, thereby releasing the limitation between the roller 41 and the limiting piece 11 and driving the moving frame 4 to lift up, so that the lower end surface of the moving frame 4 is higher than the pulley 12, so that the pulley 12 contacts the ground, thereby making it convenient for the operator to push the housing assembly 1 to slide.

[0043] Specifically, in this embodiment, by setting a locking structure, when the umbrella support frame needs to be moved, the locking structure is unlocked, causing it to move the moving frame 4. The moving frame 4 drives the roller 41 to move out of the limiting groove 112 and automatically slides along the inclined sliding surface 111, thereby releasing the limiting drive between the roller 41 and the limiting member 11 to move the moving frame 4 upward, so that the lower end surface of the moving frame 4 is higher than the pulley 12, allowing the pulley 12 to contact the ground and slide the umbrella support frame. When the umbrella support frame needs to be fixed, the locking structure is locked, causing it to move the moving frame 4. The moving frame 4 drives the roller 41 to move along the inclined sliding surface 111 and slide into the limiting groove 112, thereby locking the limiting drive between the roller 41 and the limiting member 11 to move the moving frame 4 downward, so that the lower end surface of the moving frame 4 is lower than the pulley 12, allowing the moving frame 4 to contact the ground and thus fix the umbrella support frame. The structure is simple and moving the umbrella support frame is more convenient.

[0044] Specifically, in this embodiment, by setting a locking foot pedal 21, stepping on the locking foot pedal 21 causes one end of the first operating piece 22 to move downward along the first movable groove 241, thereby causing the other end of the first operating piece 22 to move upward, thereby driving the moving frame 4 to move away from the locking foot pedal 21, thereby causing the roller 41 to lock and limit the limiting groove 112 of the limiting member 11, thereby locking the housing assembly 1 so that it cannot move.

[0045] Specifically, in this embodiment, by setting the positioning fixing piece 42, the first operating piece 22 can be better connected to the moving frame 4 to drive the moving frame 4 to move. By setting the unlocking foot pedal, stepping down on the unlocking foot pedal causes one end of the second operating piece 31 to move downward along the second movable groove 331, thereby causing the other end of the second operating piece 31 to move upward, thereby driving the first operating piece 22 to move upward, thereby driving the moving frame 4 to move towards the side closer to the unlocking foot pedal, thereby causing the roller 41 to be released from the limiting groove 112 of the limiting member 11, thereby allowing the housing assembly 1 to move.

[0046] Specifically, in this embodiment, the connecting piece 34 pries the abutment plate 25, thereby lifting the first operating piece 22 to move the roller 41 out of the limiting groove 112. A tension spring is provided to facilitate the reset of the moving frame 4 after the roller 41 leaves the limiting groove 112. The pad 43, which contacts the ground, increases the service life of the moving frame 4. A connecting rod 5 is provided to connect the umbrella.

[0047] Example 2: See Figures 10-17This application provides an umbrella support frame, including a shell assembly 1, a locking structure, and a moving frame 4. The lower end of the shell assembly 1 is provided with a limiting member 11, which is provided with an inclined sliding surface 111 and a limiting groove 112. A pulley 12 is connected to the lower end face of the shell assembly 1. The shell assembly 1 is provided with the locking structure. The moving frame 4 is connected to the shell assembly 1, and a roller 41 is provided on the moving frame 4. When the locking structure is unlocked, the motion frame 4 is driven to move, which in turn drives the roller 41 to move out of the limiting groove 112 and slide along the inclined sliding surface 111, so as to release the limiting of the roller 41 and the limiting member 11 and drive the motion frame 4 to lift up, so that the lower end surface of the motion frame 4 is higher than the pulley 12, thereby driving the housing assembly 1 to slide. The locking structure locks and drives the motion frame 4 to move, thereby driving the roller 41 to lock and limit the limiting groove 112 of the limiting member 11, and driving the motion frame 4 to descend so that the lower end surface of the motion frame 4 is lower than the pulley 12, thereby locking the housing assembly 1.

[0048] Furthermore, as a preferred embodiment, the locking structure includes a pedaling motion component 6 and a motion unlocking component 7. The pedaling motion component 6 includes a pedaling element 61, a third operating piece 62, and a second support piece 63. A connecting plate 13 is provided on the housing component 1, and a third mounting post 64 is provided on the connecting plate 13. The pedaling element 61 is disposed within the third mounting post 64, and a third movable groove 65 is provided on the third mounting post 64. The third operating piece 62 is disposed within the third movable groove 65. Stepping down on the pedaling element 61 causes the third operating piece 62 to move downward along the third movable groove 65. The second support piece 63 is connected to the connecting plate 13, and the second support piece 63 is hinged to the third operating piece 62.

[0049] Furthermore, as a preferred embodiment, the motion frame 4 is provided with a hinged fixing piece 66, and one end of the third operating piece 62 is connected to the hinged fixing piece 66.

[0050] Furthermore, as a preferred embodiment, the motion unlocking component 7 includes a fixed post 71, a sliding groove 72 on the fixed post 71, a connecting sleeve 73 on the outer sleeve of the fixed post 71, hooks 74 on both sides of the connecting sleeve 73, a connecting post 75 on the connecting sleeve 73, the connecting post 75 being slidably disposed within the sliding groove 72 and passing through the sliding groove 72 to connect with the motion pedal component 61, a fixing member 76 and a moving member 77 on the fixed post 71, the moving member 77 being disposed at the lower end of the fixing member 76 and the fixing member 76 being able to resist the movement of the moving member 77, both the fixing member 76 and the moving member 77 being able to be hooked by the hooks 74, and an elastic member 78 being disposed on the hooks 74.

[0051] Specifically, in this embodiment, a third mounting post 64 is provided on the connecting plate 13, a moving pedal component 61 is provided on the third mounting post 64, a third movable groove 65 is provided on the third mounting post 64, a third operating piece 62 is provided in the third movable groove 65, the third operating piece 62 can move downward along the third movable groove 65 following the moving pedal component 61, a second support piece 63 is provided on the connecting plate 13, the second support piece 63 and the third operating piece 62 intersect to form a lever, a hinge fixing piece 66 is provided on the moving frame 4, the third operating piece 62 intersects with the hinge fixing piece 66 to connect the third operating piece 62 to the moving frame 4.

[0052] Specifically, in this embodiment, a fixing post 71 is provided on the side of the third mounting post 64 away from the hinge fixing piece 66 on the connecting plate 13. The fixing post 71 is provided with a sliding groove 72. A connecting sleeve 73 is movably fitted on the fixing post 71. Hooks 74 are provided on both sides of the connecting sleeve 73, and elastic elements 78 are provided on the hooks 74. The elastic elements 78 are torsion springs. A connecting post 75 is provided on the connecting sleeve 73. The connecting post 75 is slidably disposed in the sliding groove 72 and passes through the sliding groove 72 to connect with the moving pedal 61. A fixing element 76 and a moving element 77 are provided on the fixing post 71. The moving element 77 is disposed at the lower end of the fixing element 76, and the fixing element 76 can resist the movement of the moving element 77. Both the fixing element 76 and the moving element 77 can be hooked by the hooks 74.

[0053] Specifically, in this embodiment, when the support base needs to be locked, the moving foot pedal 61 is stepped down, causing one end of the third operating plate 62 to move downwards and the other end of the third operating plate 62 to tilt upwards. This reduces the angle between the third operating plate 62 and the second support plate 63, simultaneously pushing the moving frame 4 to move away from the third mounting post 64. This also simultaneously drives the connecting sleeve 73 and the hook 74 to move until the hook 74 engages with the fixing member 76, locking the structure. When the synchronous drive roller 41 slides along the inclined sliding surface 111 into the limiting groove 112, the roller 41 is locked and limited by the limiting groove 112 of the limiting member 11, and a self-locking is formed by the counter-clamping angle between the second support piece 63 and the third operating piece 62, so that the roller 41 will not drive out of the limiting groove 112. The moving frame 4 is lowered so that the lower end surface of the moving frame 4 is lower than the pulley 12, so that the pad 43 of the moving frame 4 contacts the ground, so that the operator cannot push the shell assembly 1, and the position of the umbrella seat support frame is fixed.

[0054] Specifically, in this embodiment, when the support base needs to be moved, the moving foot pedal 61 is first stepped down, causing the connecting sleeve 73 to drive the hook 74 to continue moving downward. After the hook 74 hooks onto the moving part 77, the pressure on the moving foot pedal 61 is released. Under the action of the spring's rebound force, the moving frame 4 rises, thereby driving the connecting sleeve 73 to rise. When the moving part 77 touches the fixing part 76, the spring, driven by the elastic part 78, releases the hook from the moving part 77, causing the connecting sleeve 73 and the moving foot pedal 61 to reset. Simultaneously, the third operating piece 62 also resets. The movement of the moving frame 4 synchronously drives the roller 41 to move out of the limiting groove 112 and slide along the inclined sliding surface 111 until it touches the lower end surface of the base plate. This releases the limiting of the roller 41 and the limiting part 11 and drives the moving frame 4 to lift up, so that the lower end surface of the moving frame 4 is higher than the pulley 12, thereby making the pulley 12 contact the ground, thus facilitating the operator to push the housing assembly 1 to slide.

[0055] Specifically, in this embodiment, by setting a moving foot pedal 61, stepping on the moving foot pedal 61 downward causes one end of the third operating piece 62 to move downward along the third movable groove 65, thereby causing the other end of the third operating piece 62 to move upward, thereby driving the moving frame 4 to move away from the moving foot pedal 61, thereby driving the roller 41 to lock and limit the limiting groove 112 of the limiting member 11, thereby locking the housing assembly 1 so that it cannot move.

[0056] Specifically, in this embodiment, by setting the hinged fixing piece 66, the third operating piece 62 can be better connected to the motion frame 4 to drive the motion frame 4 to move.

[0057] Specifically, in this embodiment, a connecting sleeve 73 is provided on the fixed post 71. When the moving foot pedal is stepped on, the connecting sleeve 73 is driven to move, thereby driving the hook 74 to hook onto the fixed part 76, thereby moving the moving frame 4 down and locking the housing assembly 1. After the moving foot pedal is stepped on again, the hook 74 hooks onto the moving part 77 and then rebounds to reset, thereby driving the moving frame 4 up and unlocking the housing assembly 1 so that the umbrella seat can be pushed.
