[0037] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0038] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0039] In the description of the present utility model, "a plurality" refers to two or more than two. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0040] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0041] Telescopic forklifts are widely used in various industries due to their superior performance and multifunctional operation methods. For example, they are used in construction sites, field farms, port terminals, forestry and animal husbandry, etc. Telescopic forklifts generally include a chassis, a telescopic arm, a cab and an engine, etc. Among them, the telescopic arm is the core component of the telescopic forklift to achieve multifunctional operations. The telescopic arm generally includes multiple arms of different sizes, and the multiple arms are mutually nested. A slider structure is set between two adjacent arms, and relative sliding is achieved through the slider structure. In order to reduce friction, lubricating oil will be applied to the slider structure, but when the telescopic arm is under load, the lubricating oil on the slider will be squeezed out from the surface of the slider and affect the lubrication performance. Therefore, the lubricating oil needs to be replenished regularly.

[0042] If the slider structure is disassembled to add lubricating oil, it will cause troublesome disassembly and assembly, time-consuming and labor-intensive. Therefore, in the related art, an oil filling mechanism is set on the slider, which can add lubricating oil without disassembling the slider, making the operation more convenient and labor-saving. However, the existing oil filling mechanism has a complex structure and high cost, and the storage time of the lubricating oil after replenishment is short, and the lubricating oil needs to be replenished frequently, which is less practical.

[0043] To this end, the utility model proposes a slider structure, a telescopic arm frame and a telescopic arm forklift, which can effectively improve the above-mentioned problems.

[0044] Reference below Figures 1 to 4 The present invention describes a slider structure, a telescopic boom and a telescopic forklift according to embodiments of the present invention.

[0045] According to the slider structure 10 of the first embodiment of the utility model, Figures 1 to 3 As shown, the slider body 100 includes a slider body 100, which may be a rectangular parallelepiped or other suitable shapes. The slider body 100 has a first end surface 101. For example, when the slider body 100 is a rectangular parallelepiped, the surface of one side of the slider body 100 in the thickness direction may be the first end surface 101. The first end surface 101 is provided with an oil guide groove 102 and an oil storage groove 103. An oil injection hole 104 is provided on the side of the slider body 100. For example, when the slider body 100 is a rectangular parallelepiped, the oil injection hole 104 may be provided on at least one of the four side surfaces of the slider body 100. An oil passage 105 is provided in the slider body 100, and the oil passage 105 is used to connect the oil guide groove 102 and the oil injection hole 104.

[0046] When the slider structure 10 needs to be installed between two adjacent arm sections, the slider body 100 is installed on one of the arm sections so that the first end surface 101 is in contact with the other arm section, and the slider body 100 slides relatively with the other arm section.

[0047] When it is necessary to replenish the lubricating oil, the lubricating oil is injected into the oil passage 105 through the oil filling hole 104, and the lubricating oil can enter the oil guide groove 102. The oil guide groove 102 can guide the lubricating oil to different positions of the first end surface 101, and then the lubricating oil can spread to the entire first end surface 101, and even spread to other surfaces of the slider body 100 to achieve lubrication. Replenishing the lubricating oil is quick and convenient, and the structure is simple and the cost is low. In addition, an oil storage groove 103 is provided on the first end surface 101, and part of the lubricating oil flowing out of the oil guide groove 102 can enter the oil storage groove 103 for storage. At the same time, the oil guide groove 102 itself also has a certain oil storage function, so that the lubricating oil can be stored for a longer time, and there is no need to replenish the lubricating oil frequently, which is more practical.

[0048] refer to Figure 1 As shown, in some embodiments of the present invention, at least two oil guide grooves 102 are provided, and at least two oil guide grooves 102 are parallel to each other. For example, two oil guide grooves 102 can be provided, and the two oil guide grooves 102 are parallel to each other. Such a configuration can not only enable the lubricating oil to be distributed more quickly to various positions of the slider body 100 that need lubrication, and the lubricating oil replenishment efficiency is higher, but also enable the lubricating oil to be distributed more comprehensively and evenly, thereby achieving a better lubrication effect.

[0049] It should be noted that the oil guide grooves 102 may also be other numbers, for example, three, four, or more than four, which is determined according to actual needs.

[0050] refer to Figure 1 As shown, in a further embodiment of the present invention, at least two oil guide grooves 102 are arranged along the width direction of the slider body 100, and the oil guide grooves 102 extend along the length direction of the slider body 100. For example, when there are two oil guide grooves 102, the two oil guide grooves 102 are arranged along the width direction of the slider body 100, and the oil guide grooves 102 can extend to both ends of the slider body 100 along the length direction of the slider body 100. Such a configuration can not only enable the lubricating oil to be distributed more quickly to various positions of the slider body 100 that need lubrication, and the lubricating oil replenishment efficiency is higher, but also enable the lubricating oil to be distributed more comprehensively and evenly, thereby achieving a better lubrication effect.

[0051] It should be noted that in some other embodiments of the present invention, at least two oil guide grooves 102 may be arranged along the length direction of the slider body 100, and the oil guide groove 102 may extend along the width direction of the slider body 100. Such an arrangement can also improve the efficiency of lubricating oil replenishment and the lubrication effect.

[0052] refer to Figures 1 to 3As shown, in a further embodiment of the present invention, at least two oil filling holes 104 are provided and correspond one-to-one with the oil guide grooves 102 , at least two oil filling holes 104 are located on the same side of the slider body 100 , and an oil channel 105 is provided between each oil filling hole 104 and the corresponding oil guide groove 102 .

[0053] For example, when two oil guide grooves 102 are provided and arranged along the width direction of the slider body 100, and the oil guide grooves 102 extend along the length direction of the slider body 100, two oil filling holes 104 can be provided, and the two oil filling holes 104 are located on the side surfaces of the same side of the length direction of the slider body 100, and two oil passages 105 are provided, and one end of the two oil passages 105 is respectively connected to the two oil filling holes 104, and the other end of the two oil passages 105 is respectively connected to the two oil guide grooves 102.

[0054] In this embodiment, different oil guide grooves 102 are replenished with oil separately through different oil filling holes 104, and oil can be replenished according to the remaining lubricating oil in different oil guide grooves 102, with higher oil replenishment accuracy. All oil filling holes 104 are located on the same side of the slider body 100, so that oil only needs to be replenished on the same side of the slider body 100, which is more convenient.

[0055] It should be noted that in some other embodiments of the present invention, only one oil filling hole 104 may be provided, and one oil filling hole 104 simultaneously replenishes oil to multiple oil guide grooves 102. In addition, when multiple oil filling holes 104 are provided, the multiple oil filling holes 104 may also be located on different sides of the slider body 100, which will not be described in detail herein.

[0056] refer to Figure 1 As shown, in some embodiments of the present invention, the oil storage groove 103 is disposed between two adjacent oil guide grooves 102. For example, when two oil guide grooves 102 are provided, the oil storage groove 103 is located between the two oil guide grooves 102. In this embodiment, such a configuration makes it easier for the lubricating oil flowing out of the oil guide groove 102 to quickly enter the oil storage groove 103 for storage.

[0057] refer to Figure 1 As shown, in some embodiments of the present invention, at least two oil storage grooves 103 are provided, and at least two oil storage grooves 103 are arranged along the length direction of the slider body 100. For example, three oil storage grooves 103 may be provided, and the three oil storage grooves 103 are arranged along the length direction of the slider body 100. Such a configuration can not only store more lubricating oil, thereby requiring less frequent replenishment of lubricating oil, and improve practicality, but also the lubricating oil flowing out of the multiple oil storage grooves 103 can be more quickly, comprehensively and evenly spread over the first end surface 101, thereby further improving the lubrication effect.

[0058] It should be noted that the number of the oil storage grooves 103 may be other numbers, for example, two, four, or more than four, which is determined according to actual needs.

[0059] refer to Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the slider body 100 has a second end face 106 opposite to the first end face 101, and the slider body 100 is provided with a hole 107, and the hole 107 passes through the first end face 101 and the second end face 106. The slider structure 10 also includes a nut 200, and the nut 200 is arranged at one end of the hole 107 close to the second end face 106. For example, the nut 200 can be welded in the hole 107, and the end face of the nut 200 and the hole wall of the hole 107 are enclosed to form an oil storage groove 103.

[0060] When the slider structure 10 needs to be installed between two adjacent arm bodies, a threaded hole can be set on one of the arm bodies, the nut 200 on the slider structure 10 is aligned with the threaded hole, and finally the bolt is installed. The installation and removal of the slider structure 10 is convenient, and the hole position 107 is not only used to install the nut 200 and then to install the slider structure 10, but also to form an oil storage groove 103. It has multiple uses in one piece without the need to additionally open an oil storage groove 103. In addition, the lubricating oil in the oil storage groove 103 can also lubricate the nut 200 and the bolt, thereby facilitating the removal of the bolt, and can also reduce the rust of the bolt and nut 200, which is more practical.

[0061] It should be noted that in some other embodiments of the present invention, the oil storage groove 103 may be separately provided, instead of forming the oil storage groove 103 with the hole 107 for installing the nut 200. In addition, the slider body 100 may also be installed in other ways, such as by welding.

[0062] refer to Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the slider structure 10 further includes an oil cup 300, which is installed at the oil filling hole 104 and is used to inject lubricating oil into the oil passage 105. After the oil cup 300 is installed and lubricating oil is added to the oil cup 300, the oil cup 300 can store the lubricating oil and continuously and slowly inject the lubricating oil into the oil passage 105. The oil cup 300 is provided so that the staff does not need to frequently inject lubricating oil into the oil passage 105, which is more convenient to use, and the oil cup 300 can continuously and slowly inject lubricating oil into the oil passage 105, thereby achieving a better lubrication effect.

[0063] It should be noted that the oil cup 300 can be a drip-type oil cup, a wick-type oil cup or other suitable oil cup 300. The oil cup 300 is a common component in the lubrication structure, and its structure and working principle are not described in detail here. In addition, the telescopic arm forklift can also be provided with an oil pipe, which can be connected to the oil filling hole 104 to input lubricating oil into the oil filling hole 104. Of course, the staff can also directly inject lubricating oil into the oil filling hole 104.

[0064] The telescopic arm according to the second embodiment of the utility model comprises the slider structure 10 of the first embodiment.

[0065] For example, refer to Figure 4 As shown, the telescopic arm frame may include three arm bodies, one of which is a base arm 20, and the other two arm bodies are respectively a first telescopic arm 30 and a second telescopic arm 40, a slider structure 10 of the first aspect embodiment is provided between the first telescopic arm 30 and the base arm 20, and the first telescopic arm 30 and the second telescopic arm 40 are provided with a slider structure 10 of the first aspect embodiment.
