Description

Technical Field

[0001] The utility model relates to the field of electric lifting rods, in particular to an electric lifting rod structure. Background Art

[0002] An electric lift mast is a device that uses electricity to achieve vertical lifting motion and can lift and lower target objects.

[0003] At present, the Chinese patent with the announcement number CN217051453U discloses an internal wiring multi-section electric lifting rod, which belongs to the field of inspection robots. It includes a one-section sleeve, a two-section sleeve is coaxially adapted to be installed in the one-section sleeve, and a three-section sleeve is coaxially adapted to be installed in the two-section sleeve. A roller fixed relatively to the two-section sleeve is installed above the two-section sleeve, and a cable is wound around the roller. One end of the cable is relatively fixed to the one-section sleeve, and the other end of the cable is relatively fixed to the three-section sleeve. Through this structure, the lifting and lowering of the two-section sleeve can be directly controlled by the driving source to simultaneously lift the two-section sleeve and the three-section sleeve. When using the driving source of the same cost, the lifting efficiency of the lifting rod is directly improved, which solves the problem in the prior art that the lifting rod of the inspection robot is two-section and has low lifting efficiency.

[0004] After reviewing the Chinese patent with publication number CN217051453U, the applicant found the following problems: the base area proposed in the existing technical solution is relatively small. When the sleeve lifts the target object, the base is not convenient to provide stable support force, which easily leads to the target object being lifted and lowered unstably. Utility Model Content

[0005] The main purpose of the utility model is to provide an electric lifting rod structure, which aims to solve the problem proposed in the existing technical solution that the base area is small, when the sleeve lifts the target object, the base is not convenient to provide stable supporting force, which easily leads to unstable lifting of the target object.

[0006] To achieve the above-mentioned purpose, the utility model proposes an electric lifting rod structure comprising a support plate, a base body and a sleeve body, wherein support mechanisms are provided on both sides of the top of the support plate, and limit blocks are provided on both sides of the top of the support plate;

[0007] The support mechanism includes a support sleeve, two support rods and a support block. The surface of the support sleeve contacts the surface of the sleeve body. The side of the support rod close to the support sleeve is fixedly connected to the support sleeve. The bottom of the support rod is fixedly connected to the top of the support block. The bottom of the support block is in movably contact with the top of the support plate.

[0008] Preferably, the front side and the rear side of both sides of the top of the support plate are fixedly connected to the slide rails, and the side of the support block close to the slide rails extends to the inside of the slide rails and is slidably connected to the inside of the slide rails.

[0009] Preferably, both sides of the top of the support plate are provided with limiting holes, the limiting blocks are movably inserted into the limiting holes, and the surface of the limiting blocks contacts the surface of the supporting block.

[0010] Preferably, the bottom of the limiting block is fixedly connected to a magnetic plate, the bottom of the magnetic plate is magnetically attracted to the bottom of the inner wall of the limiting hole, and the top of the limiting block is fixedly connected to a pull ring.

[0011] Preferably, a push rod is fixedly connected between opposite sides of two adjacent support rods, and a surface fixing sleeve of the push rod is provided with an anti-slip sleeve.

[0012] Preferably, a rubber sealing cover is provided between the tops of the two support sleeves, the inner walls of the two support sleeves are in close contact with the surface of the rubber sealing cover, and a handle is fixedly connected to the top of the rubber sealing cover.

[0013] Preferably, the bottom of the support plate is fixedly connected with an anti-slip cone, and the number of the anti-slip cones is several and evenly distributed on the bottom of the support plate.

[0014] Preferably, a limiting groove is provided on the top of the support plate, and the surface of the base body contacts the inner wall of the limiting groove.

[0015] The support block is limited in position by the bottom of the magnetic plate at the bottom of the limit block and the bottom of the inner wall of the limit hole, so that the magnetic plate can limit the limit block and prevent the limit block from accidentally separating from the limit hole. At this time, the support block is supported by the support plate with a larger area and the anti-slip cone at the bottom of the support plate. The stable support of the support plate can make the sleeve body more stable when the sleeve body lifts the target object, thereby making the lifting of the target object more stable. After the sleeve body is completely lowered and retracted, the rubber sealing cover is moved until the surface of the rubber sealing cover is in close contact with the inner walls of the two support sleeves. The rubber sealing cover can seal the sleeve body to prevent water from entering the gap of the sleeve body when the sleeve body is not used for a long time, thereby affecting the normal operation of the internal structure. This avoids the problem that the base area proposed in the existing technical solution is small, and when the sleeve lifts the target object, the base is inconvenient to provide stable supporting force, which easily leads to the problem of unstable lifting of the target object.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0027] In addition, the terms "first," "second," and so on, used in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0028] Moreover, the technical solutions between the various embodiments of the present invention may be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0029] The utility model provides an electric lifting rod structure, which aims to solve the problem in the existing technical solution that the base area is small, the base is not convenient to provide stable supporting force when the sleeve lifts the target object, and the lifting of the target object is easily unstable.

[0030] like Figure 1-6 As shown, an electric lifting rod structure provided by an embodiment of the present invention includes a support plate 1, a base body 2 and a sleeve body 3. Support mechanisms 4 are provided on both sides of the top of the support plate 1, and limit blocks 6 are provided on both sides of the top of the support plate 1.

[0031] The support mechanism 4 includes a support sleeve 401, two support rods 402 and a support block 403. The surface of the support sleeve 401 contacts the surface of the sleeve body 3. The side of the support rod 402 close to the support sleeve 401 is fixedly connected to the support sleeve 401. The bottom of the support rod 402 is fixedly connected to the top of the support block 403. The bottom of the support block 403 is in movable contact with the top of the support plate 1.

[0032] In the technical solution of the present invention, by moving the base body 2 to the inside of the limit groove 10, and then holding the anti-slip sleeve 9 to push, the support block 403 can slide inside the slide rail 7, at this time the support rod 402 and the support sleeve 401 will also move, the support sleeve 401 is moved until the inner wall of the support sleeve 401 contacts the surface of the sleeve body 3, and then the pull ring 13 is held to insert the limit block 6 into the limit hole 11. At this time, the surface of the limit block 6 contacts the surface of the support block 403, and the support block 403 can be limited to prevent the support block 403 from moving. The bottom of the magnetic plate 12 at the bottom of the limit block 6 is magnetically attracted to the bottom of the inner wall of the limit hole 11, and the magnetic plate 12 can limit the limit block 6 to prevent the limit block 6 from accidentally separating from the limit hole 11. At this time, the magnetic plate 12 has a larger area. The support plate 1 and the anti-slip cone 15 at the bottom of the support plate 1 provide stable support for the support plate 1, which can make the sleeve body 3 more stable when the sleeve body 3 lifts the target object, thereby making the lifting of the target object more stable. After the sleeve body 3 is completely lowered and retracted, the rubber sealing cover 5 is moved until the surface of the rubber sealing cover 5 is in close contact with the inner walls of the two support sleeves 401. The rubber sealing cover 5 can seal the sleeve body 3 to prevent water from entering the gap of the sleeve body 3 when the sleeve body 3 is not used for a long time, thereby affecting the normal operation of the internal structure. This avoids the problem that the base area proposed in the existing technical solution is small, and when the sleeve lifts the target object, the base is inconvenient to provide stable supporting force, which easily leads to the problem that the lifting of the target object is not stable enough.

[0033] Please refer to Figure 3 The front and rear sides of both sides of the top of the support plate 1 are fixedly connected to the slide rails 7, and the side of the support block 403 close to the slide rails 7 extends into the interior of the slide rails 7 and is slidably connected to the interior of the slide rails 7. In this embodiment, the support block 403 is slidably connected to the interior of the slide rails 7, which facilitates the movement of the support block 403, the support rod 402, and the support sleeve 401, thereby achieving the effect of facilitating the movement of the support block 403.

[0034] For further information, please refer to Figure 3 and Figure 4 Limiting holes 11 are formed on both sides of the top of the support plate 1. The limiting blocks 6 are movably inserted into the limiting holes 11, and the surface of the limiting blocks 6 contacts the surface of the support block 403. In this embodiment, by inserting the limiting blocks 6 into the limiting holes 11, the surface of the limiting blocks 6 contacts the surface of the support block 403, thereby limiting the position of the support block 403 and preventing the support block 403 from moving, thereby achieving the effect of limiting the position of the support block 403.

[0035] Please continue to refer to Figure 4The bottom of the limit block 6 is fixedly connected to a magnetic plate 12, which is magnetically attracted to the bottom of the inner wall of the limit hole 11. The top of the limit block 6 is fixedly connected to a pull ring 13. In this embodiment, the magnetic plate 12 at the bottom of the limit block 6 is magnetically attracted to the bottom of the inner wall of the limit hole 11, so that the magnetic plate 12 can limit the limit block 6 and prevent the limit block 6 from accidentally separating from the limit hole 11, thereby achieving the effect of preventing the limit block 6 from separating from the limit hole 11.

[0036] Please refer to Figure 3 A push rod 8 is fixedly connected between the opposite sides of two adjacent support rods 402, and a non-slip cover 9 is fixedly provided on the surface of the push rod 8. In this embodiment, the support rod 402 can be easily pushed toward the side close to the sleeve body 3 by holding the non-slip cover 9, thereby achieving the effect of conveniently pushing the support rod 402.

[0037] Also, please refer to Figure 1 and Figure 5 A rubber sealing cover 5 is provided between the tops of the two support sleeves 401. The inner walls of the two support sleeves 401 are in close contact with the surface of the rubber sealing cover 5. A handle 14 is fixedly connected to the top of the rubber sealing cover 5. In this embodiment, after the sleeve body 3 is completely lowered and retracted, the rubber sealing cover 5 is moved until the surface of the rubber sealing cover 5 is in close contact with the inner walls of the two support sleeves 401. The rubber sealing cover 5 can seal the sleeve body 3, preventing water from entering the gap of the sleeve body 3 when the sleeve body 3 is not used for a long time, thereby affecting the normal operation of the internal structure. The rubber sealing cover 5 can be easily moved by holding the handle 14, thereby achieving the effect of preventing water from entering the gap of the sleeve body 3.

[0038] Please refer to Figure 6 The bottom of the support plate 1 is fixedly connected with anti-slip cones 15. The number of anti-slip cones 15 is several and evenly distributed on the bottom of the support plate 1. In this embodiment, the anti-slip cones 15 at the bottom of the support plate 1 are in contact with the ground, so that the anti-slip cones 15 can make the support plate 1 more stable, thereby achieving the effect of making the support plate 1 more stable.

[0039] Also, please refer to Figure 1 and Figure 3 The top of the support plate 1 is provided with a limiting groove 10, and the surface of the base body 2 contacts the inner wall of the limiting groove 10. In this embodiment, the base body 2 can be connected to the support plate 1 by moving the base body 2 into the limiting groove 10, thereby achieving the effect of convenient connection between the base body 2 and the support plate 1.
