Abstract
Description
Technical Field
[0001] This utility model relates to the field of equipment support, and in particular to a novel support structure for fixing mobile devices. Background Technology
[0002] Currently, mobile devices (such as mobile lighting towers) need to be supported by outriggers after being moved to a designated location to ensure the stability of the device during operation.
[0003] The existing support structure for mobile devices consists of a leg beam, a support beam movably housed within the leg beam and fixed by pins, and a hand-cranked jack leg fixed to the end of the support beam by pins (the jack leg has a connector welded to it for connection with the support beam). This support structure has the following drawbacks: 1. When the equipment is in motion, to prevent uneven road surfaces from interfering with the jack legs, the jack legs are installed with a large clearance from the ground. When the equipment needs to be secured, the four jack legs are extended by hand to lift the equipment; after use, the four jack legs are also retracted by hand. Because the extension and retraction strokes of the legs are relatively long, the operator needs to constantly crank the jacks, which is not only time-consuming and laborious but also seriously affects work efficiency. 2. The ground clearance of the jack legs cannot be adjusted, which cannot meet the equipment's usage requirements under all working conditions.
[0004] Based on this, this application provides a novel support structure for fixing mobile devices that is simple to operate and can improve work efficiency to solve the above problems. Utility Model Content
[0005] The present invention aims to solve the technical problems existing in the prior art. Therefore, the present invention provides a novel support structure for fixing mobile devices that is simple to operate and can improve work efficiency.
[0006] The technical solution adopted by this utility model to solve its technical problem is: A novel support structure for fixing mobile devices is provided, including a leg beam, a support beam movably inserted into the leg beam, a pin for fixing the leg beam and the support beam, and a hand-cranked jack leg located at the end of the support beam. The jack leg has a square cross-section and first racks on both sides along its length. The support beam has a vertically arranged square sleeve at the end away from the leg beam, which matches the shape of the jack leg. The square sleeve has outwardly protruding cavities on both sides. The jack leg is located inside the square sleeve, and the first rack on it is located in the cavity. A second rack that can mesh with the first rack is movably installed in the cavity. The inner wall of the cavity has multiple sleeves, and the back of the second rack has multiple guide shafts that movably insert with the sleeves. The distance between the second rack and the first rack is adjusted by an adjustment component.
[0007] In some alternative embodiments, the adjustment assembly includes a handle screw and a tension spring, the tension spring being disposed on the sleeve and its two ends being fixedly connected to the inner wall of the cavity and the second rack, respectively, and the handle screw being threaded through the cavity and located in the middle of the second rack.
[0008] In some alternative embodiments, a steel ball is movably embedded at the end of the handle screw that abuts against the second rack.
[0009] In some alternative embodiments, the square sleeve is welded to a connector that plugs into the support beam on the side adjacent to the cavity.
[0010] In some alternative embodiments, the support beam is fastened to the connector by multiple screws after insertion, or the support beam and the square sleeve are welded together after insertion.
[0011] In some alternative embodiments, the support beam has a plurality of pin holes along its length, the pins are elastic pins, and a bracket is provided below the leg beam near its end, on which an elastic pin is movably mounted, the elastic pin penetrating the bottom of the leg beam.
[0012] In some alternative embodiments, the end of the resilient pin protruding from the bracket is provided with a hook.
[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model can use the adjustment component to control the engagement of the first rack and the second rack to lock the jack legs, and can also disengage the two to allow the jack legs to move quickly to contact the ground and then lock the legs. The equipment can be lifted simply by shaking the crank on the top of the jack legs, which reduces the rocking stroke of the inner support feet of the legs and improves work efficiency. 2. The jack legs are movably installed inside the square sleeve, and locked by the engagement of the second rack and the first rack, which enables the adjustment of the jack legs' ground clearance, allowing the equipment to better adapt to the working conditions of the construction site.

Example
[0020] As attached Figure 1 To be continued Figure 4 As shown, this embodiment provides a novel support structure for fixing mobile devices, including a leg beam 1, a support beam 2, a pin 3, a hand-cranked jack leg 4, a square sleeve 5, a first rack 6, a second rack 7, and an adjustment assembly 8, wherein: One end of the support beam 2 is movably inserted into the leg beam 1, and the bottom of the support beam 2 is provided with multiple pin holes 2.1 along its length. The end of the leg beam 1 is provided with a pin 3, which is inserted into the pin holes of the support beam to lock it onto the leg beam. In specific implementation, when the equipment needs to be supported in a fixed position, the pin is pulled out, the support beam is pulled out to a certain length, and then the pin is inserted again to lock the support beam.
[0021] The hand-cranked jack support leg 4 has a square cross-section. The first rack 6 is fixedly installed on both sides of the jack support leg 4 along the reverse direction of the length of the jack support leg 4. The fixing method can be welding or screw fixing connection.
[0022] The end of the support beam 2 away from the leg beam 1 is provided with a vertically arranged square sleeve 5 that matches the shape of the jack leg 4. The square sleeve 5 has outwardly protruding cavities 5.1 on both sides. The jack leg 4 is located inside the square sleeve 5, and its first rack 6 is located inside the cavity 5.1. A second rack 7 that can mesh with the first rack 6 is movably installed inside the cavity 5.1. In this embodiment, the second rack is preferably installed in the cavity as follows: the inner wall of the cavity 5.1 is provided with multiple sleeves 5.2, and the back of the second rack 7 is provided with multiple guide shafts 7.1 that movably insert into the sleeves 5.2. The second rack 7.1 is movably installed inside the cavity 5.1 through the guide shafts 7.1 on its back, interlocking with the sleeves 5.2. The guide shafts not only guide the movement of the second rack but also serve as support components for the jack leg and the equipment.
[0023] The adjusting component 8 is used to adjust the distance between the second rack 7 and the first rack 6. Preferably, the adjusting component 8 in this embodiment includes a handle screw 8.1 and a tension spring 8.2. The tension spring 8.2 is disposed on the sleeve 5.2, and its two ends are respectively fixedly connected to the inner wall of the cavity 5.1 and the second rack 7. The handle screw 8.1 is threaded through the cavity 5.1 and located in the middle of the second rack 7.
[0024] Preferably, in this embodiment, a steel ball (not shown in the figure, but can be referred to as a steel ball screw) is movably embedded at the end of the abutting end of the handle screw 8.1 and the second rack 7. This design can reduce the friction between the handle screw and the second rack.
[0025] Preferably, in this embodiment, the connection between the support beam 2 and the square sleeve 5 is as follows: a connector 5.3, which is inserted into the support beam 2, is welded to the side of the square sleeve 5 adjacent to the cavity 5.1. After the support beam 2 and the connector 5.3 are inserted, they are fastened with multiple screws, or the support beam and the square sleeve are welded together after insertion.
[0026] In practice: Under normal circumstances, the jack legs are located near the bottom inside the square sleeve, giving them a large ground clearance. In this case, the jack legs only need to engage the first rack with the second rack on the outside of the square sleeve. When it is necessary to support and fix the mobile equipment, operate as follows: 1. Pull out the pin, extend the support beam to a certain length, and then insert the pin again to lock the support beam. 2. Operate the adjustment component to move the second rack, which is engaged with the first rack on one side of the square sleeve, away from the first rack. The first rack and the second rack separate, and the jack outrigger moves down to contact the ground under its own weight. 3. Then adjust the adjusting components on both sides of the square sleeve so that the two second racks engage with the first rack; 4. Extend the jack's outriggers by cranking the handle at the top of the outriggers to support the equipment; 5. After the equipment is used, it needs to be moved again. Use the hand crank of the jack legs to retract the outriggers, then adjust the adjustment components on both sides of the square sleeve to separate the two first racks and the second rack. After raising the jack legs to a certain height, tighten the handle screw on one side of the sleeve and use one of the second racks to engage with the second rack to fix the jack legs.
[0027] This embodiment enables the overall height adjustment and fixation of the jack legs. When equipment needs to be secured, the jack legs can be lowered to reduce the swing stroke of the support feet, improving work efficiency. Simultaneously, by movably housing the jack legs within a square sleeve and locking them with the engagement of the second and first racks, the ground clearance of the jack legs can be adjusted. This allows the equipment to better adapt to the working conditions of the construction site. For example, if there are steps within the area where the support beam can be extended, and the height of the steps exceeds the ground clearance of the jack legs, the support beam cannot be extended to the required length, affecting the stability of the equipment. This embodiment, however, allows for adjustment of the ground clearance of the jack legs to ensure that the support beam can be extended to the required length, guaranteeing the stability of the equipment. Example
[0028] Based on Example 1, as shown in the appendix Figure 1 As shown, the pin 3 in this embodiment is an elastic pin. The specific installation structure is as follows: a bracket 1.1 is provided below the end of the support beam 1, and an elastic pin is movably mounted on the bracket 1.1. The elastic pin passes through a pin hole at the bottom of the support beam 1. The elastic pin includes a pin rod 3.1 and a spring 3.2. The rod of the pin rod 3.1 passes through the bracket 1.1, and a limiting plate 3.3 is fixed to the rod of the pin rod 3.1. The spring 3.2 is located on the pin rod 3.1, with its two ends abutting against the bracket 1.1 and the limiting plate 3.3, respectively. In this embodiment, the end of the pin rod 3.1 protruding from the bracket (i.e., the head) is designed as a hook to facilitate pulling out the pin.
[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
