Detailed Implementation
[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0035] The following is combined with Figures 1 to 9 The following describes embodiments of the present invention.
[0036] According to embodiments of the present invention, on the one hand, such as Figures 1 to 4 As shown, a protective cover is provided, including: a first cover 1, rotatably disposed at a predetermined installation position; and a second cover 2, rotatably disposed at the predetermined installation position and adapted to rotate outside the first cover 1, so that the first cover 1 and the second cover 2 form an overlapping area with a variable range, the first cover 1 and the second cover 2 having an open state with the overlapping area gradually increasing and a closed state with the overlapping area gradually decreasing.
[0037] When the protective cover of this embodiment is opened, the electrical operating table 200 inside the protective cover is exposed for use by the staff. When the protective cover is closed, it can cover the electrical operating table 200 to protect it from dust, rain and other damage, and extend the service life of the electrical operating table 200.
[0038] In one embodiment, such as Figure 3 and Figure 4 As shown, the protective cover also includes a limiting abutment structure 3, which is disposed on the first cover 1 and the second cover 2. In the closed state, the limiting abutment structures 3 in the first cover 1 and the second cover 2 gradually approach each other to abut against each other. By setting the limiting abutment structure 3, the position of the active cover can be limited during the closing process, thereby improving the accuracy of the active cover's position.
[0039] In addition, by setting the limiting abutment structure 3, during the closing process, one of the first cover 1 and the second cover 2 can drive the other of the first cover 1 and the second cover 2 to rotate, and one of the first cover 1 and the second cover 2 can act as the active cover, and the other of the first cover 1 and the second cover 2 can act as the passive cover. Thus, the active cover drives the passive cover to rotate, realizing the linkage between the active cover and the passive cover, making the operation more convenient and improving the consistency of the movement of the first cover 1 and the second cover 2.
[0040] It is worth noting that when the first cover 1 acts as the active cover, the second cover 2 acts as the passive cover. That is, in the closed state, the first cover 1 can drive the second cover 2 to rotate. When the second cover 2 acts as the active cover, the first cover 1 acts as the passive cover. That is, in the closed state, the second cover 2 can drive the first cover 1 to rotate.
[0041] Of course, one of the first cover 1 and the second cover 2 can be the active cover, and the other of the first cover 1 and the second cover 2 can be the fixed cover. For example, the first cover 1 can be the fixed cover, and the second cover 2 can be the active cover. When the second cover 2 is rotated to be fully closed, the limiting abutment structure 3 of the first cover 1 and the second cover 2 can abut and limit the movement. Alternatively, the second cover 2 can be the fixed cover, and the first cover 1 can be the active cover. When the first cover 1 is rotated to be fully closed, the limiting abutment structure 3 of the first cover 1 and the second cover 2 can abut and limit the movement.
[0042] It should be noted that in this embodiment, please refer to... Figures 1 to 4 The first cover 1 and the second cover 2 are rotatably arranged along the same axis of rotation. Specifically, the two ends of the first cover 1 and the second cover 2 along the axis of rotation are both fan-shaped end faces. The two fan-shaped end faces of the first cover 1 and the second cover 2 are both arc-shaped cover faces. The two fan-shaped end faces of the second cover 2 are rotatably arranged outside the two fan-shaped end faces of the first cover 1. The arc-shaped cover face of the second cover 2 is rotatably arranged outside the arc-shaped cover face of the first cover 1. One fan-shaped end face of the first cover 1 and the corresponding fan-shaped end face of the second cover 2 are rotatably connected at the same hinge point at the predetermined installation position. The other fan-shaped end face of the first cover 1 and the other fan-shaped end face of the corresponding second cover 2 are rotatably connected at the same position at the predetermined installation position.
[0043] Of course, in other alternative embodiments, the first cover 1 and the second cover 2 may not be rotatably arranged along the same axis of rotation, that is, the first cover 1 and the second cover 2 are not rotatably connected to the same hinge point. Specifically, the axis of rotation of the first cover 1 and the axis of rotation of the second cover 2 are arranged parallel to each other.
[0044] It is worth noting that, please refer to Figure 3 and Figure 4 In a cross section perpendicular to the axis of rotation, the first cover 1 and the second cover 2 have an overlapping area. The overlapping area is minimal when the first cover 1 and the second cover 2 are completely closed; the overlapping area gradually increases as the first cover 1 and the second cover 2 are gradually opened; the overlapping area is maximum when the first cover 1 and the second cover 2 are completely open; and the overlapping area gradually decreases as the first cover 1 and the second cover 2 are gradually closed.
[0045] In one embodiment, such as Figure 3 and Figure 4 As shown, the limiting and abutting structure 3 includes a first abutting member 31 and a second abutting member 32. The first abutting member 31 is connected to the first cover 1, and the second abutting member 32 is connected to the second cover 2. Along the rotation direction of the first cover 1 and the second cover 2, the first abutting member 31 and the second abutting member 32 are arranged opposite to each other. Specifically, when the first cover 1 and the second cover 2 are in the closed state, the first abutting member 31 and the second abutting member 32 gradually approach each other until they abut against each other, and achieve linkage under the action of the abutting force; when the first cover 1 and the second cover 2 are in the open state, the first abutting member 31 and the second abutting member 32 gradually move away from each other.
[0046] Furthermore, in this embodiment, as Figure 3 and Figure 4 As shown, the first abutting member 31 is a flange formed by folding the edge of the first cover 1, and the second abutting member 32 is a flange formed by folding the edge of the second cover 2.
[0047] It is worth noting that, please refer to Figure 3 and Figure 4 The locations of the first abutment 31 and the second abutment 32, as well as the portion between the first abutment 31 and the second abutment 32, form an overlapping area.
[0048] As an alternative implementation, the limiting abutment structure 3 includes an abutment member and a guide groove. The abutment member is disposed on one of the first cover 1 and the second cover 2, and the guide groove is formed on the other of the first cover 1 and the second cover 2. The abutment member is inserted into the guide groove and can move relative to it along the guide groove. The guide groove extends along the rotation direction of the first cover 1 and the second cover 2. In the closed state, the abutment member and one end wall of the guide groove gradually approach each other to abut against each other. Specifically, when the first cover 1 and the second cover 2 are in the closed state, the abutment member and one end wall of the guide groove gradually approach each other until they abut against each other, and achieve linkage under the action of the abutment force; when the first cover 1 and the second cover 2 are in the open state, the abutment member and one end wall of the guide groove gradually move away from each other, and the abutment member can move relative to each other within the guide groove.
[0049] It should be noted that in the above alternative embodiments, when the abutment is disposed on the first cover 1, the guide groove is formed on the second cover 2; when the abutment is disposed on the second cover 2, the guide groove is formed on the first cover 1. It can be understood that when the first cover 1 is the active cover, the second cover 2 is the passive cover, and when the second cover 2 is the active cover, the first cover 1 is the passive cover. The phrase "the abutment is inserted into the guide groove and can move relative to it along the guide groove" means that when the abutment is disposed on the active cover, the corresponding guide groove is disposed on the passive cover, and the abutment can move along the guide groove under the drive of the active cover; when the abutment is disposed on the passive cover, the corresponding guide groove is disposed on the active cover, and the guide groove moves under the drive of the active cover, causing the abutment to move relative to it within the guide groove.
[0050] It is worth noting that under the abutting action of the first abutting member 31 and the second abutting member 32, or under the abutting action of the abutting member and the groove wall at one end of the guide groove, the position of the active cover can be limited, and the linkage between the first cover 1 and the second cover 2 can also be realized. The overall structure of the limiting abutting structure 3 is simple and easy to process and form.
[0051] In one embodiment, such as Figure 3 , Figure 4 and Figure 7 As shown, the protective cover also includes a fixing structure, which is installed on the active cover. In the closed state, the fixing structure gradually approaches and connects to the fixing position at the predetermined installation location. In the open state, the fixing structure separates from the fixing position. By setting the fixing structure and cooperating with the limiting abutment structure 3, both the active and driven covers are kept in the closed state simultaneously, ensuring the stability of the active and driven covers in the closed state and improving the protection of the electrical operating console 200.
[0052] It is worth noting that by fixing the active cover in the closed state through the fixing structure, the driven cover is also fixed in the closed state under the action of the abutting force between the first abutting member 31 and the second abutting member 32.
[0053] In one embodiment, such as Figure 7 As shown, the fixing structure includes a first magnetic chuck 4, which is disposed on the active cover. A second magnetic chuck 5 is disposed at a predetermined installation position. Along the rotation direction of the active cover, the first magnetic chuck 4 and the second magnetic chuck 5 are arranged opposite to each other, with the side of the second magnetic chuck 5 facing the first magnetic chuck 4 forming a fixed position. The attractive force of the first magnetic chuck 4 and the second magnetic chuck 5 is used to fix the position of the active cover. The fixing method is simple and easy to operate. It can be understood that when it is necessary to open the protective cover, only an external force needs to be applied to the active cover to overcome the attractive force of the first magnetic chuck 4 and the second magnetic chuck 5 to open the active cover.
[0054] Of course, in other alternative implementations, the fixing structure can also be of other structural forms, such as by snapping or plugging the fixing structure with the predetermined installation position, or by fasteners (such as bolts, pins, etc.) to secure the fixing structure to the predetermined installation position.
[0055] In one embodiment, such as Figure 7 As shown, the fixed structure extends away from the active cover and is positioned opposite the edge of the driven cover. During the opening of the active cover, it abuts against the edge of the driven cover to drive the driven cover to open synchronously. After both the active and driven covers are fully open, the driven cover limits the fixed structure, ensuring that the active cover remains stably in the open state.
[0056] In one embodiment, such as Figure 1 and Figure 2 As shown, the protective cover also includes a guide protrusion 6 and a guide recess 7. The guide protrusion 6 is provided on one of the outer surface of the first cover 1 and the inner surface of the second cover 2, while the guide recess 7 is provided on the other. The guide protrusion 6 is inserted into the guide recess 7 and can move relative to it. Both the guide protrusion 6 and the guide recess 7 extend along the rotation direction of the first cover 1 and the second cover 2. Using the matching guide protrusion 6 and guide recess 7, the first cover 1 and the second cover 2 are guided and limited during opening and closing, ensuring the stability of their movement and the accuracy of their position.
[0057] It is worth noting that when the outer surface of the first cover 1 is provided with a guide protrusion 6, the inner surface of the second cover 2 is provided with a guide recess 7; when the outer surface of the first cover 1 is provided with a guide recess 7, the inner surface of the second cover 2 is provided with a guide protrusion 6.
[0058] In one embodiment, such as Figure 1 and Figure 2 As shown, a handle 8 is provided on the outer surface of the active cover. By providing the handle 8, it is convenient for the staff to hold the handle 8 and rotate the active cover to open and close the protective cover.
[0059] In one embodiment, the first cover 1 and the second cover 2 may be made of fiberglass. Of course, the first cover 1 and the second cover 2 may also be made of other materials that can provide protection.
[0060] According to an embodiment of the present invention, on the other hand, as... Figures 5 to 9As shown, a work hopper is also provided, comprising: a work hopper body 100 having a predetermined installation position; an electrical operating table 200 disposed on the work hopper body 100; and the aforementioned protective cover disposed on the work hopper body 100 and covering the electrical operating table 200. This arrangement allows the electrical operating table 200 to be exposed when the protective cover is open for easy use by personnel, and when the protective cover is closed, it covers the electrical operating table 200 to protect it from dust, rain, and other damage, thus extending the service life of the electrical operating table 200.
[0061] In one embodiment, such as Figure 8 and Figure 9 As shown, a blocking structure 300 is provided on the main body 100 of the work bucket. In the open state, the edges of the active cover and / or the driven cover gradually approach and abut against the blocking structure 300. By providing the blocking structure 300, the active cover and / or the driven cover are limited when they are in the open state, so that the active cover and / or the driven cover are stably kept in the open state.
[0062] Furthermore, in this embodiment, as Figure 7 and Figure 9 As shown, when the active and passive covers are fully open, one edge of the passive cover abuts against the blocking structure 300 for limitation, and the first magnetic suction member 4 abuts against the other edge of the passive cover for limitation. Thus, both the active and passive covers can be stably maintained in the open position.
[0063] Specifically, such as Figures 5 to 8 As shown, the main body 100 of the work bucket includes a work bucket guardrail 110 and a mounting plate 120. The work bucket guardrail 110 encloses and forms a working space. The mounting plate 120 is connected to the work bucket guardrail 110 and is located within the working space. The electrical operating console 200 is set on the mounting plate 120. The first cover 1 and the second cover 2 are both rotatably connected to the mounting plate 120.
[0064] It is worth noting that, please refer to Figure 7 The active cover is provided with first magnetic attraction 4 at both ends of the rotation axis (i.e., on the two fan-shaped end faces), and correspondingly, the electric operating table 200 is provided with second magnetic attraction 5 on both sides of the opposite sides.
[0065] In one embodiment, the blocking structure 300 is an elastic pad, such as a rubber pad. This allows for cushioning when the active and / or driven shield comes into contact with the blocking structure 300, preventing damage to the protective shield.
[0066] The working process of the protective cover in this embodiment will be described below with the first cover 1 as the driven cover and the second cover 2 as the active cover.
[0067] When the first cover 1 and the second cover 2 are in the closed state and need to be opened, an external force is applied to the second cover 2 by the handle 8, causing the first magnetic suction member 4 to separate from the second magnetic suction member 5. During the rotation of the second cover 2, the first magnetic suction member 4 abuts against one side edge of the first cover 1 and pushes the first cover 1 to open simultaneously until the other side edge of the first cover 1 abuts against the blocking structure 300 and is limited. The first magnetic suction member 4 abuts against the edge of the first cover 1, and both the first cover 1 and the second cover 2 are opened to the correct position.
[0068] When the first cover 1 and the second cover 2 are in the open state and need to be closed, an external force is applied to the second cover 2 by the handle 8, causing the first magnetic suction member 4 to rotate toward the second magnetic suction member 5. During the rotation of the second cover 2, the first abutting member 31 and the second abutting member 32 gradually approach each other until they abut against each other, and when the second cover 2 continues to rotate, it drives the first cover 1 to rotate synchronously until the first magnetic suction member 4 and the second magnetic suction member 5 attract and fix each other, and both the first cover 1 and the second cover 2 are completely closed.
[0069] According to an embodiment of the present invention, in another aspect, a working machine is also provided, including the above-described working bucket.
[0070] It is worth noting that in this embodiment, the operating machinery is an aerial fire truck.
[0071] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
