[0048] In order to better understand the above technical solutions, the technical solutions of the embodiments of the present application will be described in detail below through the accompanying drawings and specific embodiments. It should be understood that the specific features in the embodiments of the present application and the embodiments are detailed descriptions of the technical solutions of the embodiments of the present application, and are not limitations of the technical solutions of the present application. In the case of no conflict, the technical features in the embodiments of the present application and the embodiments can be combined with each other.
[0049] As Figures 1-3 shown, according to the embodiments of the present application, an anti-falling mobile workbench is provided, which comprises: a workbench body 100, the workbench body 100 is provided with universal wheels, the workbench body 100 slides through the universal wheels; a tread ring 200, the tread ring 200 is arranged on the lower side of the workbench body 100, the tread ring 200 is a ring-shaped metal component; an anti-falling foot 300, the top end of the anti-falling foot 300 is arranged on the tread ring 200, when the workbench body 100 is inclined to the direction where the anti-falling foot 300 is arranged, the lower end of the anti-falling foot 300 contacts the ground; a rubber sleeve 400, the rubber sleeve 400 is arranged on the lower end of the anti-falling foot 300, when the workbench body 100 is inclined to the direction where the anti-falling foot 300 is arranged, the lower end of the anti-falling foot 300 contacts the ground through the rubber sleeve 400.
[0050] The anti - fall mobile workbench provided by the embodiment of the present application includes a workbench body 100, a tread ring 200, anti - fall feet 300, and rubber sleeves 400.
[0051] Among them, the workbench body 100 is a bench body with universal wheels on the periphery of the base. In this embodiment, because the workbench needs to be applied to a narrow processing site, the height of the workbench is set to 500 mm, and the width of the workbench base universal wheels after expansion is limited to less than 430 mm. For a workbench with this base width, if no additional measures are taken, there is a risk of slipping for the user.
[0052] Among them, the tread ring 200 is arranged on the lower side of the workbench body 100. The tread ring 200 can reinforce the lower end of the workbench body 100 and reduce the risk of deformation. At the same time, when the user is sitting on the workbench body 100, the user can put their feet on the tread ring 200, which can make the user's sitting posture more comfortable and conform to ergonomics. However, at the same time, when the user puts their feet on the tread ring 200, it further increases the risk of the workbench slipping.
[0053] Among them, the anti - fall feet 300 are arranged on the tread ring 200. As shown in the figure, the anti - fall feet 300 are specifically "ji" - shaped metal strips. The upper end of the anti - fall feet 300 is fixedly connected to the tread ring 200, and the lower end of the anti - fall feet 300 extends to both sides. This setting can reduce the self - weight of the anti - fall feet 300 while trying to expand the width of the support of the anti - fall feet 300. When the workbench body 100 tilts in the direction where the anti - fall feet 300 are set, the anti - fall feet 300 can contact the ground, thereby achieving the technical effect of preventing the workbench from completely toppling.
[0054] Among them, the rubber sleeves 400 are arranged at one end of the anti - fall feet 300 that contacts the ground. When the anti - fall feet 300 contact the ground, the rubber sleeves 400 contact the ground. Because the friction coefficient of the rubber sleeves 400 is relatively large, it can further enhance the anti - fall effect of this workbench.
[0055] In this technical solution, a tread ring 200, anti - fall feet 300, and rubber sleeves 400 are added to the workbench body 100. When the workbench body 100 is placed stably, the workbench can slide by virtue of the universal wheels. When the workbench tilts in the direction where the anti - fall feet 300 are set, before the workbench completely topples, the anti - fall feet 300 contact the ground and provide support for the workbench, which can effectively reduce the risk of falling. At the same time, adding rubber sleeves 400 further increases the stability of the workbench. This setting can reduce the width of the workbench base while improving the stability of the workbench through the anti - fall feet 300, enabling the workbench to be used in a narrow production space and avoiding the risk of falling.
[0056] Such as Figures 1-3As shown, the workbench body 100 comprises: a bench surface 110 for providing a seatable plane for the workbench body 100; upper supports 120 which are strip-shaped support rods, the upper ends of the plurality of upper supports 120 being uniformly distributed on the circumferential side of the lower end of the bench surface 110; a middle support 130 which is a short rod, the lower ends of the plurality of upper supports 120 being connected to the upper side of the side surface of the middle support 130, the plurality of upper supports 120 being in a tapered shape from the bench surface 110 to the middle support 130; lower supports 140 which are strip-shaped support rods, the upper ends of the plurality of lower supports 140 being connected to the lower side of the side surface of the middle support 130, the lower ends of the plurality of lower supports 140 being uniformly distributed on the circumferential side of the tread ring 200; and casters 150 which comprise connecting plates and universal wheels, the number of the casters 150 being consistent with the number of the lower supports 140, the casters 150 being connected to the lower ends of the lower supports 140 through the connecting plates.
[0057] In this technical solution, the workbench body 100 comprises the bench surface 110, the upper supports 120, the middle support 130, the lower supports 140 and the casters 150.
[0058] The bench surface 110 is a seatable plane for a user, the upper supports 120 are used for supporting the bench surface 110, and the upper supports 120 are a plurality of support rods which are gradually tapered in the direction extending downward from the bench surface 110.
[0059] The middle support 130 is a short rod, and the plurality of upper supports 120 are connected to the middle support 130 after being tapered, as shown in the figure, in this embodiment, the middle support 130 is a hollow round rod.
[0060] The lower supports 140 are a plurality of support rods, and the lower supports 140 are used for providing a mounting basis for the universal wheels, and the plurality of lower supports 140 are in a radial shape in the direction extending downward from the middle support 130.
[0061] The casters 150 comprise universal wheels, and the casters 150 are arranged at the lower ends of the lower supports 140.
[0062] As shown, Figures 1-3 The anti-falling foot 300 is arranged between the two casters 150.
[0063] In this technical solution, the anti-falling foot 300 is arranged between the two casters 150, and it can be understood that one anti-falling foot 300 is arranged between every two casters 150, and through experiments, it is found that the user usually takes the two casters 150 as fulcrums to lift the workbench, and therefore, the anti-falling foot 300 arranged between the two casters 150 can achieve the best anti-falling effect.
[0064] It is understandable that the anti-fall foot 300 should be equidistant from the casters 150 on both sides.
[0065] like Figures 1-3 As shown, when the work stool body 100 is stably placed on the ground, the horizontal height of the lower end of the anti-fall foot 300 is higher than the lower end of the caster 150; when the work stool body 100 is stably placed on the ground, the lower end of the anti-fall foot 300 does not contact the ground; when the work stool body 100 is tilted 3.5 degrees to 5 degrees towards the anti-fall foot 300, the anti-fall foot 300 contacts the ground.
[0066] In this technical solution, when the work stool body 100 is stably placed on the ground, the horizontal height of the lower end of the anti-fall foot 300 is higher than the lower end of the caster 150. This setting allows the work stool to slide normally when it is stable. When the work stool is tilted 3.5 to 5 degrees relative to the direction of the anti-fall foot 300, the anti-fall foot 300 touches the ground, which can stabilize the work stool before it falls over.
[0067] like Figures 1-3 As shown, there are four upper supports 120; four lower supports 140; four casters 150; and four anti-fall feet 300.
[0068] In this technical solution, there are four upper supports (120), four lower supports (140), four casters (150), and four anti-fall feet (300).
[0069] In order to reduce the width of the work stool base when unfolded, the number of anti-fall feet 300 is reduced from the usual five to four. In order to match the number of casters 150 and make the support of the work stool consistent, the number of lower supports 140 and upper supports 120 is also four.
[0070] Each pair of casters 150 is equipped with a safety foot 300, therefore, there are a total of four safety feet 300.
[0071] like Figures 1-3 As shown, the side of the rubber sleeve 400 that contacts the ground has an anti-slip pattern.
[0072] In this technical solution, the side of the rubber sleeve 400 that contacts the ground is provided with anti-slip patterns. This feature can further increase the coefficient of friction when the anti-fall foot 300 contacts the ground, and further enhance the anti-fall effect of the work stool.
[0073] like Figures 1-3 As shown, it also includes a connector, wherein the anti-fall foot 300 is connected to the foot ring 200 via the connector.
[0074] The technical solution also includes a connector, through which the anti-fall foot 300 is connected to the foot ring 200.
[0075] It is understandable that there are multiple anti-fall feet 300, and at least one of them can be connected by a connector.
[0076] In this embodiment, there are four anti-fall feet 300. One anti-fall foot 300 is connected to the pedal ring 200 by a connector, and the other anti-fall feet 300 are connected to the pedal ring 200 by welding.
[0077] like Figures 1-3 As shown, the connecting component includes: a pivot shaft, the anti-fall foot 300 is connected to the foot ring 200 via the pivot shaft, the pivot shaft has a fixed end disposed on the foot ring 200 and a rotating end disposed on the anti-fall foot 300, the rotating end is rotatably connected to the fixed end; the rotating end has a first angle and a second angle, when the rotating end is at the first angle, when the work stool body 100 is stably placed on the ground, the anti-fall foot 300 contacts the ground; when the rotating end is at the second angle, the anti-fall foot 300 is tilted up at a certain angle, when the work stool body 100 is stably placed on the ground, the anti-fall foot 300 does not contact the ground, when the work stool body 100 is tilted towards the anti-fall foot 300, the anti-fall foot 300 contacts the ground.
[0078] In this technical solution, the connector includes a pivot, and the anti-fall foot 300300 is connected to the foot ring 200 through the pivot. The pivot has a first angle and a second angle. When the pivot is at the first angle, the anti-fall foot 300300 directly contacts the ground. At this time, the anti-fall foot 300300 plays a role in fixing the work stool body 100, so that the work stool will not slide easily. It is suitable for applicable scenarios where the user does not need the work stool to slide.
[0079] When the pivot is at the second angle, the anti-fall foot 300300 tilts up at a certain angle relative to the pivot when it is at the first angle. At this time, the work stool can slide freely. When the work stool tilts toward the anti-fall foot 300, the anti-fall foot 300 can support the ground before the work stool completely tilts over.
[0080] In this setting, the angle of the anti-fall foot 300 can be changed by changing the angle of the pivot, so that the work stool can switch between two states: stable on the ground and sliding. This makes the work stool suitable for more applicable scenarios. For example, when assembling products, a more stable working environment is required, so the work stool can be made stable on the ground. When it is necessary to move from one workstation to another, the work stool can be made to slide freely.
[0081] like Figures 1-3As shown, the connecting piece further comprises a limiting assembly, the limiting assembly comprises a convex block and a sleeve, the limiting assembly is used for fixing the rotating end of the rotating shaft at a first angle or a second angle.
[0082] In the technical scheme, when the sleeve slides on the rotating shaft, the convex block changes the position according to the height of the sliding groove due to the limiting of the sliding groove, the rotating end of the rotating shaft changes the angle due to the driving of the convex block, and the anti-falling foot 300 changes the position due to the driving of the rotating shaft.
[0083] When the sleeve slides to one end, the rotating shaft is at the first angle, and when the sleeve slides to the other end, the rotating shaft is at the second angle.
[0084] Through the arrangement, the rotating shaft can be stably fixed at the first angle or the second angle, and the switching between the first angle and the second angle is very convenient.
[0085] As shown in the drawings, Figures 1-3 The connecting piece further comprises a sliding plate, and the sliding plate is fixedly connected with the sleeve.
[0086] In the technical scheme, the connecting piece further comprises a sliding plate, and the sliding plate is arranged on the sleeve, so that the sleeve can slide from one end to the other end by pulling the sliding plate.
[0087] It can be understood that, in the embodiment, the sliding plate is arranged in a shape that can be pulled by the user through the foot, so as to further simplify the operation required when switching between the two forms of the workbench.
