Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0036] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "top", "bottom", "inside" and "outside" etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation of the present invention.

[0038] The invention aims to provide a rapid disassembly device for repairing windshield wipers of electric train sets, which can quickly and conveniently disassemble the windshield wipers.

[0039] To achieve the above object, the present invention provides the following technical solutions:

[0040] Please refer to Figures 1 to 6. This embodiment provides a quick disassembly device for maintenance of EMU wipers, including: a limit seat 100, a threaded push rod 200 and a connecting handle 300; a cavity for accommodating the wiper mounting part 01 is provided in the middle of the limit seat 100, a baffle 110 is fixed on the top, and a connecting base 120 is provided at the bottom, and the limit seat 100 is used to fix and limit the wiper mounting part 01; the threaded push rod 200 is arranged through the connecting base 120, and the threaded push rod 200 is threadedly connected to the connecting base 120, and the threaded push rod 200 is used to push the rocker 02 out of the wiper mounting part 01; the connecting handle 300 is vertically connected to the end of the threaded push rod 200 away from the limit seat 100, and the outer sides of the two ends of the connecting handle 300 are provided with external anti-slip sheaths.

[0041] Specifically, the overall structure of the limit seat 100 is half of a cylinder, and a semicircular baffle 110 is fixed on the top thereof, wherein the inner diameter of the baffle 110 is smaller than the inner diameter of the limit seat 100, and the shape of the connecting base 120 can be a cylindrical structure, or can be the shape shown in FIG2, which is not specifically limited herein. The wiper is rotatably mounted on the rocker 02 through the wiper mounting portion 01. When the disassembly device provided in this embodiment is used, the limit seat 100 can be fitted onto the circumferential surface of the wiper mounting portion 01, and the baffle 110 can be abutted against the lower side of the wiper mounting portion 01, as shown in FIG1. ​​At the same time, the threaded push rod 200 will pass through the connecting base 120 and act on the top of the rocker 02. In this way, as the threaded push rod 200 continues to push in, the limit seat 100 will drive the wiper mounting portion 01 to move in the opposite direction, thereby completing the disassembly of the wiper.

[0042] That is to say, when in use, it is only necessary to engage the limit seat 100 with the wiper mounting part 01. In the engaged state, the axis of the limit seat 100 is parallel to the axis of the rocker 02 on which the wiper is installed. Then, by rotating the threaded top rod 200, the threaded top rod 200 acts on the top of the rocker 02. At the same time, the baffle 110 of the limit seat 100 engages the other end of the wiper mounting part 01, so that the wiper is completely separated from the rocker 02. In this way, the wiper can be quickly disassembled.

[0043] Preferably, a guide sleeve 130 is vertically penetrated through the center position of the connecting base 120, and a threaded push rod 200 is inserted into the guide sleeve 130. The outer circumference of the threaded push rod 200 and the inner circumference of the guide sleeve 130 are provided with matching threads, and a connecting base plate 140 is fixedly connected to both sides of the bottom end of the guide sleeve 130, and a mounting protrusion 150 is fixedly connected to the upper side of the connecting base plate 140. Fixed mounting grooves 160 matching the mounting protrusion 150 are provided on both sides of the bottom end of the connecting base 120 to fix the guide sleeve 130.

[0044] In this embodiment, in order to facilitate the assembly and disassembly of the device at any time, a cylindrical guide sleeve 130 is vertically installed at the center of the connecting base 120, and a certain gap is left between the outer circumference of the guide sleeve 130 and the connecting base 120 to reduce the friction between the two. The interior of the guide sleeve 130 is provided with a thread matching the threaded push rod 200. At the same time, in order to prevent the guide sleeve 130 from rotating when the threaded push rod 200 is screwed, this embodiment is provided at the bottom of the guide sleeve 130 through the connecting bottom plate 140. The mounting protrusion 150 corresponds to a mounting groove 160 which cooperates with the mounting protrusion 150 and is correspondingly provided at a corresponding position on the lower side of the connecting base 120, as specifically shown in FIGS. 3 and 6 . When the guide sleeve 130 is installed in place, the mounting protrusion 150 will engage with the mounting groove 160, and then the guide sleeve 130 will cooperate with the external thread of the threaded push rod 200 by using the thread on its inner wall to play a guiding role. In this way, after the disassembly device has been used for many times, the guide sleeve 130 may be worn to a certain extent. In this case, it is only necessary to replace the guide sleeve 130, which can save costs.

[0045] Preferably, a support sleeve 400 is detachably mounted on the bottom end of the threaded push rod 200 , and the support sleeve 400 is vertically connected to the center of the connecting handle 300 .

[0046] Specifically as shown in Figure 3, in order to facilitate the connection between the threaded push rod 200 and the connecting handle 300, a sleeve is sleeved on the lower end of the threaded push rod 200, so that when assembling and disassembling the device, it is only necessary to install the threaded push rod 200 into the supporting sleeve 400, which greatly reduces its production difficulty; such a setting can also facilitate replacement when the connecting handle 300 or the threaded push rod 200 is damaged.

[0047] Moreover, installing the threaded push rod 200 at the center position of the connecting handle 300 also makes it convenient for the staff to apply force for rotating the threaded push rod 200, thereby improving the convenience of using the disassembly device.

[0048] Preferably, side reinforcing ribs 410 are provided on both sides of the support sleeve 400 , and the side reinforcing ribs 410 connect the support sleeve 400 and the connecting handle 300 .

[0049] Furthermore, in order to enhance the overall strength of the support sleeve 400 and the connecting handle 300 , two side reinforcing ribs 410 are symmetrically provided on both sides of the support sleeve 400 .

[0050] Preferably, a plurality of groups of anti-slip grooves 320 are arranged on the outer circumference of the outer anti-slip sheath.

[0051] Specifically, as shown in FIG. 5 , a plurality of grooves 320 are provided on the outer circumference of the outer anti-slip sheath. The plurality of grooves 320 on the surface of the outer anti-slip sheath can enhance the friction of the hand contact surface, effectively prevent slipping during rotation, improve the experience of the rotation operation, and reduce pain.

[0052] Preferably, mounting plates 330 are radially penetrated at both ends of the connecting handle 300 close to the outer anti-slip sleeve to prevent the outer protective sleeve 310 from axial movement, and the mounting plates 330 are inserted into mounting slots 340 provided on the connecting handle 300.

[0053] It is understandable that when the staff rotates the connecting handle 300, the outer protective sleeve 310 may slide along the axis of the connecting handle 300. Therefore, in the present embodiment, four groups of mounting slots 340 are provided on the connecting handle 300. The four groups of mounting slots 340 are respectively arranged at the two ends of the two outer protective sleeves 310, as shown in FIGS. 3 and 5. Correspondingly, the mounting plates 330 are inserted into the mounting slots 340. The length of the mounting plates 330 is greater than the diameter of the outer protective sleeve 310. That is to say, the outer protective sleeve 310 is fixed by setting the mounting plates 330 at its two ends.

[0054] Preferably, a circle of reinforcing inner plate 350 is fixedly connected to the outer circumference of the connecting handle 300 , and the outer protective sleeve 310 is installed to the outer circumference of the reinforcing inner plate 350 .

[0055] It can be understood that such a configuration is to further enhance the strength of the connecting handle 300 to prevent the connecting handle 300 from being bent during rotation, thereby increasing the service life of the disassembly device.

[0056] Preferably, the outer protective sleeve 310 is connected to the reinforced inner plate 350 via an adhesive 360 ​​.

[0057] In this embodiment, the outer protective sleeve 310 is preferably installed on the outer circumference of the reinforced inner plate 350 through an adhesive 360. Of course, the specific type of the adhesive 360 ​​can be selected according to actual conditions.

[0058] Preferably, a protective plate 500 is laid on the inner wall of the cavity in the middle of the limiting seat 100 by installing screws 510 , and a receiving groove is provided on the protective plate 500 , and the receiving groove is used for positioning and installing the screws 510 .

[0059] In addition, in order to extend the service life of the limit seat 100 and prevent the wiper mounting part 01 from causing excessive damage to the limit seat 100, the present embodiment also lays a layer of protective plate 500 on the inner wall of the cavity in the middle of the limit seat 100. The protective plate 500 is fixed to the inner wall of the limit seat 100 by installing screws 510, and the number and fixing positions of the installing screws 510 can be adjusted according to actual needs, which are not specifically limited in this article.

[0060] It should be noted that a receiving groove is provided at the position where the protective plate 500 is fixed. The receiving groove is specifically a countersunk hole, which can be used to position the mounting screw 510 to prevent the head of the mounting screw 510 from protruding and affecting the fixation of the wiper mounting part 01.

[0061] Preferably, the outer protective sleeve 310 and the protective plate 500 are both made of elastic material.

[0062] It can be understood that the material of the outer protective sleeve 310 and the protective plate 500 is preferably elastic material, which can not only enhance the comfort of the staff during use, but also prevent the protective plate 500 from colliding with the wiper and being damaged.

[0063] In summary, the present embodiment provides a quick disassembly device for repairing the windshield wiper of an EMU. Firstly, the multiple groups of grooves 320 on the surface of the outer anti-skid sheath are used to enhance the friction of the hand contact surface, effectively preventing slipping during rotation, improving the experience of the rotation operation, and reducing pain. By means of the engaging structure between the mounting plate 330 and the mounting slot 340, the outer anti-skid sheath can be fixedly mounted on the outside of both sides of the connecting handle 300 to avoid the outer anti-skid sheath from falling off during use. The firmness between the outer anti-skid sheath and the connecting handle 300 is enhanced by the adhesive 360. When the outer anti-skid sheath is damaged, it is convenient to disassemble and replace it, thereby optimizing the operation steps. Secondly, by setting the protective plate 5 00 is on the inner wall of the cavity inside the limit seat 100 to enhance its surface protection, to avoid the wiper mounting part 01 causing friction damage to the inner wall of the limit seat 100 during disassembly, which affects the subsequent use, and extends the service life of the limit seat 100. At the same time, the accommodating groove can be used to shield the mounting screw 510, to avoid the mounting screw 510 protruding during use and causing damage to the wiper; finally, the mounting protrusions 150 on both sides of the bottom end of the guide sleeve 130 are engaged and fixed in the interior of the fixed mounting groove 160, and the guide sleeve 130 is inserted into the interior of the limit seat 100, and the internal thread of the inner wall is used to guide the rotation of the threaded rod to avoid the threaded rod from tilting during rotation.

[0064] When in use, the wiper mounting part 01 that needs to be disassembled is placed on the hollow part of the limit seat 100, and the threaded push rod 200 is moved to the inside of the guide sleeve 130 by rotating the external thread. The wiper mounting part 01 is limited inside the limit seat 100 to ensure that the wiper mounting part 01 cannot move. The staff holds the connecting handle 300 and rotates it quickly, so that the threaded push rod 200 pushes the rocker 02, and the wiper is pulled out from the rocker 02 under the action of the reaction force. The reasonable use of the wiper maintenance tool can provide strong protection for the safety of the staff under the influence of an unfavorable safety environment, and avoid forced risky operations that may cause harm to the staff.
