Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to an engine underbody protection plate mounting device. Background Technology

[0002] Engine underbody protection plates are important protective components installed at the bottom of a car engine. They are mainly used to prevent damage to critical components such as the engine oil pan and transmission from impacts by flying stones, mud and water erosion, and when the engine bottoms out.

[0003] Currently, engine underbody plates are usually directly fixed to the vehicle frame with multiple bolts. This installation method requires a lot of time to remove multiple bolts with a specific size wrench when oil changes or vehicle maintenance are needed. The removal is time-consuming and laborious, which greatly reduces the efficiency of vehicle maintenance. Utility Model Content

[0004] The purpose of this invention is to provide an engine underbody protection plate mounting device to solve the above problems, which enables quick installation and removal of the protection plate, thereby improving the efficiency of automobile maintenance.

[0005] This utility model achieves the above objectives through the following technical solutions: An engine underbody protection plate mounting device includes a threaded post, one end of which is provided with a connector. A positioning block is integrally formed on the connector, and the positioning block engages with the threaded post. The connector is provided with a fixing structure, which includes a connecting seat and a movable block. The connecting seat is threadedly connected to the connector, and the movable block is slidably connected to the connecting seat. An annular groove is provided on the outer side of the movable block. Multiple locking blocks are slidably connected to the positioning block. One end of each locking block engages with the threaded post, and the other end of each locking block abuts against the movable block.

[0006] As a preferred embodiment, a limit ring is fixedly connected to the outer side of the movable block, and a spring is sleeved on the outer side of the movable block.

[0007] In a preferred embodiment, one end of the spring abuts against the movable block, and the other end of the spring abuts against the positioning block.

[0008] As a preferred embodiment, one end of the movable block is fixedly connected to a pressure plate, and the width of the vertical cross-section of the pressure plate is greater than the width of the cross-section of the movable block.

[0009] As a preferred embodiment, one end of the connecting seat is integrally formed with a protrusion, the width of the vertical cross-section of the protrusion is greater than the width of the cross-section of the pressure plate, and the transverse cross-section of the protrusion is a hexagonal structure.

[0010] As a preferred embodiment, the transverse cross-section of the connector is hexagonal, and the vertical cross-section of one end of the threaded post is trapezoidal.

[0011] As a preferred embodiment, the horizontal cross-section of the positioning block is square, the vertical cross-section of one end of the positioning block is trapezoidal, and the vertical cross-section of the other end of the connecting seat is trapezoidal.

[0012] As a preferred embodiment, the vertical cross-section of the end of the card block is semi-circular, and the four card blocks are arranged in a circumferential array about the center of the positioning block.

[0013] As a preferred embodiment, the outer side of the connector is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are distributed in a circumferential array about the center of the connector.

[0014] As a preferred embodiment, a gasket is fitted on the outer side of the threaded post, and the width of the vertical cross-section of the gasket is greater than the width of the cross-section of the connector.

[0015] Compared with the prior art, the present invention has the following beneficial effects: When the protective plate needs to be removed for vehicle maintenance, this utility model allows for the pressing of a pressure plate, which in turn moves a movable block. This movable block moves the annular groove towards a locking block. When one side of the pressure plate contacts the connecting seat, the end of the locking block aligns perfectly with the center of the annular groove. Then, the connector can be held to separate the positioning block from the threaded post. Because the cross-section of the locking block's end is semi-circular, the positioning block moves towards the annular groove under the contact of the threaded post as it disengages from the threaded post. Continue pulling the connector until the positioning block and the threaded post separate. Repeat the above operation to remove all connectors used to fix the protective plate from the threaded post. Then, the protective plate can be removed for vehicle maintenance. Since only a certain amount of time is needed to twist the threaded post during the initial installation of the protective plate, subsequent installations only require pressing the pressure plate to achieve quick disassembly and installation of the protective plate, thus effectively improving the efficiency of vehicle maintenance.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4 As shown, this utility model embodiment provides an engine underbody protection plate mounting device, including a threaded post 1, a connector 2 at one end of the threaded post 1, a positioning block 3 integrally formed on the connector 2, the positioning block 3 engaging with the threaded post 1, a fixing structure 4 on the connector 2, the fixing structure 4 including a connecting seat 401 and a movable block 402, the connecting seat 401 being threadedly connected to the connector 2, the movable block 402 being slidably connected to the connecting seat 401, an annular groove 403 being provided on the outer side of the movable block 402, a plurality of locking blocks 404 being slidably connected to the positioning block 3, one end of the locking block 404 engaging with the threaded post 1, the other end of the locking block 404 abutting against the movable block 402, a limit ring 405 being fixedly connected to the outer side of the movable block 402, a spring 406 being sleeved on the outer side of the movable block 402, one end of the spring 406 abutting against the movable block 402, and the other end of the spring 406 abutting against the positioning block 3. One end of the movable block 402 is fixedly connected to a pressure plate 407. The width of the vertical section of the pressure plate 407 is greater than the width of the section of the movable block 402, thus increasing the pressing area of ​​the hand and improving the comfort of operation. At the same time, when the pressure plate 407 abuts against the connecting seat 401, the annular groove 403 is located on one side of the locking block 404, thus facilitating the movement of the locking block 404 under the abutment of the threaded column 1 inside the annular groove 403.

[0020] Specifically, in this embodiment, during use, a wrench is used to thread the threaded post 1 onto the mounting bracket of the engine underbody protection plate inside the connector 2. The connector 2 allows the gasket 6 to abut against the underbody protection plate, thereby fixing the underbody protection plate. When the protective plate needs to be removed for vehicle maintenance, the pressure plate 407 can be pressed. The pressure plate 407 will drive the movable block 402 to move, and the movable block 402 will drive the annular groove 403 to move towards the locking block 404. When one side of the pressure plate 407 abuts against the connecting seat 401, the end of the locking block 404 is just aligned with the middle of the annular groove 403. Then, the connector 2 can be held to separate the positioning block 3 and the threaded post 1. Because the cross-section of the end of the locking block 404 is semi-circular, during the process of the positioning block 3 disengaging from the threaded post 1, it will move towards the annular groove 403 under the resistance of the threaded post 1, continuously pulling the connector 2 until the positioning block 3 and the threaded post 1 are separated. Then, repeat the above operation to remove all the connectors 2 used to fix the protective plate from the threaded post 1. Then the protective plate can be removed for car maintenance. Since it only takes a certain amount of time to twist the threaded post 1 when installing the protective plate for the first time, subsequent simple pressing of the pressure plate 407 can achieve quick disassembly and installation of the protective plate, thereby effectively improving the efficiency of car maintenance.

[0021] To further optimize this embodiment, one end of the connecting seat 401 is integrally formed with a protrusion 408. The width of the vertical cross-section of the protrusion 408 is greater than the width of the cross-section of the pressure plate 407. The transverse cross-section of the protrusion 408 is hexagonal, thus facilitating the use of a socket wrench to twist the connecting seat 401 onto the connecting head 2 from the outside of the protrusion 408, thereby simplifying the installation of the connecting seat 401. The vertical cross-section of the end of the locking block 404 is semi-circular. Therefore, when the annular groove 403 is located at one end of the locking block 404, the threaded post 1 can move towards the inside of the annular groove 403 by contacting the locking block 404 during the pulling of the connecting head 2. The four locking blocks 404 are arranged in a circumferential array about the center of the positioning block 3. The simultaneous engagement of multiple locking blocks 404 with the threaded post 1 improves the firmness of the connection between the positioning block 3 and the threaded post 1.

[0022] Please see Figures 1 to 4As shown, the transverse cross-section of connector 2 is hexagonal, allowing the threaded post 1 to be easily screwed into the protective plate mounting bracket from the outside using a socket wrench. The vertical cross-section of one end of the threaded post 1 is trapezoidal, thus guiding its movement when inserted into the mounting hole of the protective plate mounting bracket. The transverse cross-section of positioning block 3 is square, allowing it to be engaged with the threaded post 1 to position connector 2 and prevent rotation between connector 2 and threaded post 1. The vertical cross-section of one end of positioning block 3 is trapezoidal, guiding its movement when inserted into the threaded post 1. The vertical cross-section of the other end of connector seat 401 is trapezoidal, guiding its movement during installation inside connector 2.

[0023] Please see Figures 1 to 4 As shown, the outer side of the connector 2 is provided with multiple anti-slip grooves 5, which are arranged in a circumferential array about the center of the connector 2. Therefore, the gripping resistance can be increased when moving the connector 2, thus facilitating the movement of the connector 2. A washer 6 is sleeved on the outer side of the threaded post 1. The width of the vertical cross-section of the washer 6 is greater than the width of the cross-section of the connector 2. Therefore, it can disperse the pressure of the connector 2 on the surface of the protective plate, thereby avoiding damage to the protective plate.
