DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0038] In the prior art, the right side rearview mirror mounting seat of engineering machinery such as medium and large tonnage cranes is generally fixed to the machine shed 8 by bolts. However, in this way, during installation, it is necessary to tighten the bolts with the help of tools such as wrenches, which is inconvenient to operate and affects the assembly efficiency.

[0039] Therefore, the utility model provides a novel rearview mirror mounting device, in which the mounting bracket and the fixing seat 4 adopt the matching form of the card slot 6 and the card connection part 7, which is convenient for plugging and unplugging and easy for disassembly and assembly, and solves the problem that the existing bolt connection requires the use of tools, which is inconvenient to operate and reduces the assembly efficiency.

[0040] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0041] Please refer to Figures 1 to 11 As shown, the embodiment of the utility model provides a rearview mirror installation device, including a mounting bracket and a fixing seat 4. Specifically, the mounting bracket is used to install the rearview mirror 1, and the fixing seat 4 is suitable for being installed on the machine shed 8 of the working machine. Specifically, as Figure 1As shown, taking a crane as an example, a cab 9 is arranged on the left side of the crane turntable, and a shed 8 is arranged on the right side. The fixing seat 4 is pre-installed on the front side of the shed 8, and then the mounting bracket can be held by hand for plugging and unplugging connection with the fixing seat 4, so that the rearview mirror 1 can be installed on the side of the shed 8 through the rearview mirror installation device. In this way, the operator sitting in the cab 9 can observe in real time whether there are obstacles on the right rear that hinder the normal operation of the machine, and whether there are any abnormalities in the counterweight 10 at the right rear tail, through the rearview mirror 1 installed on the front of the right shed 8. Generally, if Figure 3 As shown, the rearview mirror 1 adopts a convex mirror to obtain a larger field of view. Figure 1 For the placement of the operating machinery shown in the figure, the left and right directions in the figure refer to the front and back directions, and the up and down directions in the figure refer to the left and right directions.

[0042] In this embodiment, one of the mounting bracket and the fixing seat 4 is provided with a card slot 6, and the other is provided with a card connection portion 7 adapted to the card slot 6, and the card connection portion 7 is inserted into the card slot 6. In other words, the card slot 6 can be provided on the mounting bracket, and the card connection portion 7 can be provided on the fixing seat 4. Alternatively, the card connection portion 7 can be provided on the mounting bracket, and the card slot 6 can be provided on the fixing seat 4. Thus, the card connection portion 7 is adapted to the card slot 6, and the card connection portion 7 is inserted into the card slot 6, so that the mounting bracket and the fixing seat 4 form a plug-in structure, thereby realizing the fixing of the rearview mirror 1 to the side of the shed 8.

[0043] In this way, the clamping portion 7 cooperates with the clamping slot 6 to form a plug-in connection mode. During the assembly and disassembly process of the rearview mirror 1, only the mounting bracket needs to be held and the assembly with the fixing seat 4 can be completed by plugging and pulling out the bracket up and down, thereby realizing the rapid assembly and disassembly of the rearview mirror 1. It has a simple structure, reliable connection, convenient operation, and no auxiliary tools are required, which solves the problems of cumbersome operation, inconvenience in use, and low efficiency caused by the existing bolt connection.

[0044] In the embodiment of the present utility model, Figure 5 As shown, the mounting bracket is provided with a slot 6. Figure 7 As shown, the fixing seat 4 is provided with a matching clamping portion 7. At the same time, the clamping slot 6 is set as a wedge-shaped slot, and the cross-sectional area of ​​the clamping slot 6 gradually increases from the upper end to the lower end of the clamping slot 6. Thus, the clamping slot 6 forms a structure that is small at the top and large at the bottom. Correspondingly, the clamping portion 7 is also designed to be a structure that is small at the top and large at the bottom. Specifically, as Figure 5As shown, the slot 6 on the mounting bracket opens downward. During installation, the operator holds the mounting bracket and inserts it downward, and the clamping portion 7 enters the slot 6 from bottom to top. Since the two are designed as a wedge-shaped structure with a small top and a large bottom, there is a large gap during the initial matching, which facilitates the insertion of the clamping portion 7 into the slot 6. As the mounting bracket gradually descends, the matching gap gradually decreases until the clamping portion 7 is in full contact and fit with the slot 6. Through the friction of the inclined surface and the gravity of the rearview mirror 1 and the mounting bracket, the mounting bracket and the fixing seat 4 are more closely matched and the connection is more stable, thereby ensuring the stability of the connection and the convenience of disassembly and assembly. It should be noted that, as shown in the following Figure 5 As for the placement position of the rearview mirror mounting device shown in the figure, the up-down direction in the figure is the up-down position, and the cross section obtained by the intersection of the plane perpendicular to the up-down direction and the slot 6 is the cross section of the slot 6.

[0045] In addition, in this embodiment, Figures 8 to 11 As shown, the slot 6 has five sliding surfaces, namely, a first sliding surface 61, a second sliding surface 62, a third sliding surface 63 and two fourth sliding surfaces 64. Specifically, the second sliding surface 62 and the third sliding surface 63 are arranged opposite to each other and are respectively connected to the first sliding surface 61. The two fourth sliding surfaces 64 are arranged opposite to the first sliding surface 61. One fourth sliding surface 64 is connected to the second sliding surface 62, and the other fourth sliding surface 64 is connected to the third sliding surface 63. In other words, the first sliding surface 61, the second sliding surface 62 and one fourth sliding surface 64 together form a groove portion, and the first sliding surface 61, the third sliding surface 63 and the other fourth sliding surface 64 together form another groove portion. Among them, the first sliding surface 61, the second sliding surface 62 and the third sliding surface 63 can be designed as inclined surfaces, and the fourth sliding surface 64 can be designed as a plane, wherein the inclination angle of each inclined surface needs to be specifically determined according to the actual use situation to meet the design requirements of the structural size.

[0046] Correspondingly, if Figure 7As shown, the matching mating surfaces on the clamping portion 7 need to be adaptively designed according to the specific structure of the clamping slot 6. Specifically, the clamping portion 7 has a first mating surface 71, a second mating surface 72, a third mating surface 73 and two fourth mating surfaces 74. The first mating surface 71 is arranged correspondingly to the first sliding surface 61, the second mating surface 72 is arranged correspondingly to the second sliding surface 62, the third mating surface 73 is arranged correspondingly to the third sliding surface 63, and the two fourth mating surfaces 74 are arranged correspondingly to the two fourth sliding surfaces 64. The first mating surface 71, the second mating surface 72 and one fourth mating surface 74 together form a clamping portion, and the first mating surface 71, the third mating surface 73 and another fourth mating surface 74 together form another clamping portion. One clamping portion is suitable for sliding and being clamped in one slot portion, and the other clamping portion is suitable for sliding and being clamped in another slot portion. In this way, the two fourth sliding surfaces 64 and the two fourth matching surfaces 74 facilitate the positioning and matching of the card slot 6 and the card connection portion 7, and the remaining three inclined surface designs form a more compact wedge-shaped quick-insertion structure, making the connection tighter and more stable.

[0047] Of course, in other embodiments, a card slot 6 may be provided on the fixing seat 4, and a corresponding card connection portion 7 may be provided on the mounting bracket. At this time, the opening of the card slot 6 should face upward, and the cross-sectional area of ​​the card slot 6 should gradually decrease from top to bottom, that is, a wedge-shaped slot structure with a larger top and a smaller bottom is formed. Correspondingly, the card connection portion 7 is adjusted to a structure with a larger top and a smaller bottom. During installation, the operator holds the mounting bracket and inserts it downward, so that the card connection portion 7 enters the card slot 6 from top to bottom until the two are completely fitted. In this way, the inclined surface can also be used to achieve a close fit between the two, so as to achieve a stable connection and quick disassembly and assembly.

[0048] As an optional embodiment of the present utility model, Figure 2 As shown, the mounting bracket includes a mounting frame 2 and a mounting seat 3. Specifically, the mounting seat 3 is connected to the fixing seat 4, and the mounting seat 3 is provided with a card slot 6 or a card connection portion 7, so that the two can be quickly disassembled and assembled by plugging. One end of the mounting frame 2 is connected to the mounting seat 3, and the other end is used to connect to the rearview mirror 1, and the mounting frame 2 is set as an integrated structure. In this way, compared with the traditional welding connection bracket, the mounting frame 2 is integrally formed, has a higher structural strength, and has better stability, which is conducive to reducing the shaking and displacement of the rearview mirror 1 when the crane is in operation.

[0049] Further, in the embodiment of the present utility model, if Figure 6 As shown, the mounting seat 3 is provided with a first assembly hole 31, specifically, as Fig. 9As shown, the first assembly hole 31 can be set as a blind hole. The mounting frame 2 is inserted into the first assembly hole 31, and the mounting frame 2 and the first assembly hole 31 are interference-fitted. In this way, the mounting frame 2 and the mounting seat 3 form an interference fit of the shaft hole, which is convenient for plugging and unplugging the mounting frame 2. The connection structure is simple, reliable and stable. At the same time, the angle of the mounting frame 2 can be arbitrarily rotated under the action of external force, thereby adjusting the angle of the rearview mirror 1.

[0050] In a specific embodiment of the present invention, Figure 4 As shown, the mounting frame 2 includes a first connecting portion 21, a second connecting portion 22 and a third connecting portion 23 which are bent and connected in sequence. Specifically, the mounting frame 2 can be formed by bending a common steel pipe in one piece, and its structural strength is high, which meets the installation requirements of the rearview mirror 1 bracket and has low manufacturing cost. The first connecting portion 21 and the third connecting portion 23 are arranged along the height direction of the mounting bracket, thereby extending in the vertical direction to form the main supporting structure of the mounting frame 2, which meets the installation height requirements of the rearview mirror 1. And the first connecting portion 21 is connected to the mounting seat 3, specifically, the first connecting portion 21 is inserted into the first assembly hole 31, and the first connecting portion 21 and the first assembly hole 31 are interference fit, thereby forming a fastening connection, and at the same time, the angle of the mounting frame 2 and the rearview mirror 1 can be adjusted by any rotation angle under the action of external force. The third connecting portion 23 is used to connect with the rearview mirror 1, specifically, the third connecting portion 23 can be fixedly connected to the rearview mirror 1 through a buckle and a bolt assembly, so as to ensure the connection stability of the third connecting portion 23 and the rearview mirror 1 in the locked state. Furthermore, the rearview mirror 1 can also rotate a certain angle on the third connecting portion 23 to achieve fine adjustment of the angle of the rearview mirror 1, so that the angle of the rearview mirror 1 is adjusted to the best observation position for the operator, thereby improving the safety of the operation. Among them, the rearview mirror 1 can use an existing mature rearview mirror assembly, so its specific structure is not repeated here. For example, it has a spherical pair matching structure inside, which can achieve the angle adjustment of the rearview mirror 1. It should be noted that, with Figure 4 For the placement position of the rearview mirror mounting device shown in the figure, the up and down directions in the figure refer to the vertical direction and the height direction of the mounting bracket.

[0051] Further, in the embodiment of the present utility model, if Figure 4As shown, the second connection part 22 is inclined, and along the direction from the first connection part 21 to the third connection part 23, the inclination height of the second connection part 22 gradually increases. In other words, the second connection part 22 forms an inclined upward structure, so that the bending connection between the first connection part 21 and the third connection part 23 is realized through the second connection part 22, and the necessary bending angle and adjustment space are provided so that the mounting frame 2 can adapt to different installation environments and requirements. At the same time, the structural shape is simple and beautiful, which improves the stress condition of the mounting frame 2 and is conducive to improving the overall strength of the mounting frame 2. It can be understood that the inclination angle of the second connection part 22 needs to be specifically determined according to the actual design requirements. It should be noted that, as shown in the figure, Figure 4 For the placement position of the rearview mirror mounting device shown in the figure, the up and down directions in the figure refer to the up and down positions and height directions.

[0052] In addition, if Figure 4 As shown, the connection between the first connection part 21 and the second connection part 22, and the connection between the second connection part 22 and the third connection part 23 are all designed with transition fillets, so that the change of the bending radius is more gentle, the stress distribution becomes more uniform, and the stress concentration at the connection is avoided, thereby improving the fatigue life and overall strength of the mounting frame 2. In addition, the transition fillet can also improve the manufacturing processability of the mounting frame 2, reduce the processing difficulty, improve the processing accuracy, and reduce the manufacturing cost. Therefore, the connection between the first connection part 21 and the second connection part 22, and the connection between the second connection part 22 and the third connection part 23 adopt a transition fillet design, which not only optimizes the structural performance of the mounting frame 2 and improves its durability, but also simplifies the processing technology and reduces the manufacturing cost.

[0053] In an optional embodiment of the present utility model, as Figure 5 As shown, the mounting base 3 is provided with a gripping portion 32. Specifically, the mounting base 3 has a pair of opposite gripping portions 32, so as to conform to the gripping method of the operator and facilitate handheld plugging and installation. Furthermore, the gripping portion 32 is provided with a groove 33, so as to facilitate the insertion of fingers and facilitate gripping during disassembly and assembly. Specifically, the number of grooves 33 is at least two, and they are spaced apart along the height direction of the mounting base 3. It can be understood that the number, size, shape and other parameters of the grooves 33 can be specifically determined according to actual design requirements. It should be noted that, as shown in FIG. Figure 5 As for the placement position of the rearview mirror mounting device shown in the figure, the up and down direction in the figure is the height direction of the mounting seat 3.

[0054] As an optional embodiment of the present utility model, Figure 7As shown, the fixing base 4 is provided with a second assembly hole 41 for connecting the hangar 8, wherein the second assembly hole 41 can be designed as a plain hole or a threaded hole. Thus, the fixing base 4 can be pre-fixed on the side of the hangar 8 by inserting fasteners 5 such as bolts, and it is convenient for assembly and maintenance. At the same time, the second assembly hole 41 is set as a countersunk hole, so as to prevent the end of the fastener 5 from protruding from the surface of the fixing base 4, avoid interference when the clamping portion 7 and the clamping groove 6 are matched, ensure stable and reliable connection between the mounting bracket and the fixing base 4, and also make the structural size more compact.

[0055] Further, in an optional embodiment of the present utility model, as Figure 7 As shown, there are at least two second assembly holes 41, and each second assembly hole 41 is spaced apart along the height direction of the fixing base 4. This arrangement realizes a multi-point connection between the fixing base 4 and the shed 8, and supports and fixing points can be added at different positions, which helps to enhance its structural strength, improve the stability of the overall structure, and ensure the reliability and durability of the overall structure. In addition, the fixing base 4 and the mounting base 3 can be designed as open mold structural parts, so that batch production can be carried out, which greatly improves production efficiency, ensures the dimensional accuracy and shape consistency of the parts, and also helps to reduce the overall manufacturing cost. It should be noted that, with the following Figure 7 As for the placement position of the rearview mirror mounting device shown in the figure, the up and down direction in the figure is the height direction of the fixing seat 4.

[0056] In summary, the embodiment of the utility model provides a rearview mirror mounting device with a simple structure and high reliability, which specifically includes a mounting frame 2, a mounting seat 3 and a fixing seat 4. The mounting frame 2 is formed by bending in one piece, and has a simple structure, high strength and good stability. One end of the mounting frame 2 can be fixedly connected to the rearview mirror 1 through a buckle and a bolt assembly, and the other end is fastened to the first assembly hole 31 on the mounting seat 3 through an interference fit. In this way, a stable connection of the various components can be achieved, and the mounting frame 2 can also be rotated under the action of an external force to achieve the angle adjustment of the mounting frame 2 and the rearview mirror 1, and the operation is convenient and simple. In addition, the rearview mirror 1 itself can also be rotated and adjusted to further adjust the angle of the rearview mirror 1 so that it is finally in the best observation position.

[0057] The rearview mirror 1, the mounting frame 2 and the mounting seat 3 are matched with the clamping part 7 through the clamping slot 6, and are plugged and fixed on the fixing seat 4. The fixing seat 4 can be pre-installed on the side of the hangar 8 by the bolt assembly, so that the rearview mirror 1 is installed and fixed on the hangar 8. Among them, the clamping slot 6 and the clamping part 7 are correspondingly designed as a wedge-shaped structure, so that the mounting seat 3 and the fixing seat 4 are matched through the inclined surface. As the handheld mounting seat 3 is inserted into the fixing seat 4, the inclined surface and the gravity of the rearview mirror 1, the mounting frame 2 and the mounting seat 3 are used to ensure the stability of the connection on the one hand, and on the other hand, the disassembly process can be completed by hand-held plugging and unplugging without the help of tools, eliminating the cumbersome operation, inconvenience in use, low efficiency and other problems caused by the traditional bolt connection. In addition, a groove 33 is provided on the mounting seat 3 to facilitate the hand's force grip during plugging and unplugging. In addition, the second assembly hole 41 on the fixing seat 4 is set as a countersunk hole structure to ensure that the bolt end cap does not protrude from the inclined side of the fixing seat 4, and can make the structural size more compact.

[0058] The working machine provided by the utility model is described below. The working machine described below and the rearview mirror mounting device described above can be referred to each other.

[0059] The embodiment of the utility model also provides a working machine, specifically, the working machine is, for example, a crane. The working machine includes a rearview mirror installation device as described in the above embodiments. With such a configuration, the clamping portion 7 cooperates with the clamping slot 6 to form a plug-in connection mode. The assembly and disassembly process of the rearview mirror 1 only requires holding the mounting bracket, and the assembly with the fixing seat 4 can be completed by plugging and unplugging with force up and down, thereby realizing the rapid assembly and disassembly of the rearview mirror 1. It has a simple structure, reliable connection, convenient operation, and no auxiliary tools are required, which solves the problems of cumbersome operation, inconvenience in use, and low efficiency caused by the existing bolt connection. The derivation process of this beneficial effect is roughly similar to the derivation process of the beneficial effect of the above rearview mirror installation device, so it will not be repeated here. In the embodiment of the utility model, the type of working machine does not constitute a limitation, and the working machine includes but is not limited to a crane, and can also be an excavator, a loader, etc. In other words, as long as the working machine can use the rearview mirror installation device in the utility model.
