Description

Technical Field

[0001] This utility model relates to the field of automotive underbody protection plate processing technology, and in particular to an experimental fixture for underbody protection plates. Background Technology

[0002] A car underbody protection plate, also known as a chassis guard or chassis skid plate, is a protective plate installed on the bottom of a car. Its main function is to prevent mud, stones, water and other debris from damaging chassis parts, while protecting the bottom electronic equipment and exhaust system, reducing the impact and wear of road debris on the chassis, and helping to extend the service life of the chassis.

[0003] A search revealed Chinese patent CN219704772U, which discloses a bottom plate experimental fixture, comprising: a support; and connectors, wherein the connectors are mounted on the top of the support and correspond one-to-one with the positioning holes on the edge of the bottom plate; wherein the connectors include multiple connecting rods, which are interlocked by pins; the bottom plate is clamped between two adjacent connecting rods, and the pins on the connecting rods pass through the positioning holes on the outside of the bottom plate. This invention, by employing interlocking connecting rods to clamp the bottom plate between them, effectively solves the technical problem of existing bottom plate fixtures that can only fix a single bottom plate and are cumbersome to install. It achieves positioning of the bottom plate and also allows for stacking of bottom plates as needed, improving the fixture's load-bearing capacity and economic efficiency.

[0004] The experimental fixture for the underbody protection plate in the aforementioned patent has the following shortcomings: During the inspection or processing, the docking rod and the underbody protection plate may be collided due to operator error, which may cause displacement of the docking rod and the underbody protection plate. This may cause the pin to come out of the hole on the docking rod, resulting in the inability to stably clamp the underbody protection plate, which will affect the normal progress of the inspection or processing work. Therefore, it is urgent to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an experimental fixture for bottom protection plates.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An experimental fixture for a bottom protective plate includes two support frames. Two support platforms are fixedly connected to the top of the two support frames. Two bases are fixedly connected to the top of each support platform. Several mating plates are provided on the top of each base. Insertion slots are formed on the top of each base and mating plate. First insertion holes are formed on each base and mating plate, communicating with the insertion slots. Sleeves are fixedly connected to both sides of each base and mating plate. Limiting rods are threaded through the sleeves and slidably connected to the sleeves. Return springs are sleeved on the limiting rods and located on one side of the sleeves. Two limiting rods at the same end are fixedly connected to the same connecting plate. An insertion rod is fixedly connected to the connecting plate near the limiting rod, and the insertion rod is adapted to the first insertion hole. A fixing rod is fixedly connected to the bottom of the mating plate. An insertion plate is fixedly connected to the bottom of the fixing rod, and the insertion plate has a first insertion hole. The system employs a dual-socket design, where the second socket is adapted to the plug rod. By using a technique that restricts the position of the plug plate by inserting the plug rod into the first and second sockets, the position of the car underbody protection plate and the docking plate will not shift even under external impact when the plug rod is within the first and second sockets. This ensures stable clamping of the car underbody protection plate, effectively solving the problem mentioned in the background technology where operator error during inspection or processing could cause collisions with the docking rod and the car underbody protection plate, potentially leading to displacement of the docking rod and the plug pin coming out of the hole on the docking rod, resulting in unstable clamping of the car underbody protection plate and affecting the normal operation of inspection or processing. This system improves clamping stability and reliability, prevents displacement or falling due to collisions or operator error, and ensures stable and normal operation of inspection or processing.

[0008] Preferably, the insert plate is adapted to the insertion slot.

[0009] Preferably, a first support plate is fixedly connected to the same side of both support platforms, and a plurality of first brackets are provided on the side of the two first support plates near the support platform, and the first brackets are fixedly connected to the two first support plates.

[0010] Preferably, pads are provided at the top of both ends of the first bracket.

[0011] Preferably, a second support plate is fixedly connected to the top of each of the two support platforms.

[0012] Preferably, each of the two second support plates is fixedly connected with a plurality of second brackets that are equidistantly distributed on the side that is close to each other.

[0013] Preferably, the connecting plate has a handle fixedly connected to the side away from the limiting rod.

[0014] The beneficial effects of this utility model are as follows:

[0015] Because of the technical means of using a plug rod to restrict the position of the insert plate by inserting it into the first and second insert holes, when the plug rod is in the first and second insert holes, even if it is subjected to external force, the position of the car underbody protection plate and the docking plate will not be displaced. This can stably clamp the car underbody protection plate, effectively solving the problem mentioned in the background technology that during the inspection or processing process, the docking rod and the car underbody protection plate may be displaced due to operator error, which may cause the plug pin to come out of the hole on the docking rod, resulting in the inability to stably clamp the car underbody protection plate and affecting the normal operation of the inspection or processing work. Thus, it achieves the technical effect of improving the stability and reliability of clamping, preventing displacement or falling due to collision or operator error, and ensuring that the inspection or processing work can be carried out stably and normally.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3An experimental fixture for a bottom protective plate includes two support frames 1. Two support platforms 2 are fixedly connected to the top of the two support frames 1. Two bases 3 are fixedly connected to the top of each support platform 2. Several mating plates 4 are provided on the top of each base 3. Insertion slots 5 are provided on the top of both the bases 3 and the mating plates 4. First insertion holes 6 are provided on both the bases 3 and the mating plates 4, communicating with the insertion slots 5. Sleeve plates 7 are fixedly connected to both sides of the bases 3 and the mating plates 4. Limiting rods 8 pass through the sleeve plates 7 and slide on them. Return springs 9 are sleeved on the limiting rods 8 and are located on one side of the sleeve plates 7. Two limiting rods 8 at the same end are fixedly connected to the same connecting plate 10. Insert rods 11 are fixedly connected to the connecting plate 10 on the side near the limiting rods 8, and these insert rods 11 are adapted to the first insertion holes 6. A fixing rod 12 is fixedly connected to the bottom of the mating plates 4, and an insertion plate 13 is fixedly connected to the bottom of the fixing rod 12. Insert plates 13 are provided on the insertion plates 13. A second insertion hole 14 is provided, which is adapted to the insertion rod 11. Due to the technical means of restricting the position of the insertion plate by inserting the insertion rod into the first and second insertion holes, even if the vehicle underbody protection plate and the docking plate are subjected to external force collision when the insertion rod is in the first and second insertion holes, the position of the vehicle underbody protection plate and the docking plate will not be displaced. It can stably clamp the vehicle underbody protection plate, effectively solving the problem mentioned in the background technology that during the inspection or processing, the docking rod and the vehicle underbody protection plate may be collided due to the operator's operation error, which may cause the docking rod and the vehicle underbody protection plate to be displaced, which may cause the pin to fall out of the hole on the docking rod, resulting in the inability to stably clamp the vehicle underbody protection plate, which will affect the normal operation of the inspection or processing work. Thus, it achieves the technical effect of improving the stability and reliability of clamping, preventing displacement or falling due to collision or operator error, and ensuring that the inspection or processing work can be carried out stably and normally.

[0022] In this utility model, the insert plate 13 is adapted to the insertion slot 5. The insert plate 13 is inserted into the insertion slot 5 to pre-connect the docking plate 4 and the base 3, as well as the docking plate 4 and another docking plate 4.

[0023] In this utility model, a first support plate 16 is fixedly connected to the same side of both support platforms 2. Several first brackets 17 are provided on the side of the two first support plates 16 near the support platform 2, and the first brackets 17 are fixedly connected to the two first support plates 16.

[0024] In this utility model, pads 18 are provided at the top of both ends of the first bracket 17. By providing pads 18, the first bracket 17 and pads 18 can fit against the car underbody protection plate and support the car underbody protection plate.

[0025] In this invention, a second support plate 19 is fixedly connected to the top of each of the two support platforms 2.

[0026] In this utility model, two second support plates 19 are each fixedly connected to a plurality of second brackets 20 that are equidistantly distributed on the side that is close to each other, and the two ends of the car underbody protection plate are supported by the second brackets 20.

[0027] In this utility model, the connecting plate 10 has a handle 15 fixedly connected to the side away from the limiting rod 8.

[0028] Working principle: In use, place the car underbody protection plate on the second bracket 20, the first bracket 17, and the pad 18, which are on the same horizontal plane. Then, pass the insert plate 13 through the mounting hole of the car underbody protection plate, so that the fixing rod 12 is in the mounting hole of the car underbody protection plate. Insert the insert plate 13 into the insertion slot 5 for pre-connection. Before inserting the insert plate 13 into the insertion slot 5, pull the handle 15 to move the handle 15. The handle 15 will drive the connecting plate 10 to move, and the connecting plate 10 will drive the insert rod 11 to move out of the first insertion hole 6. During the movement of the connecting plate 10, it will also drive the limiting rod 8 to move along the sleeve plate 7 to ensure the stability of the connecting plate 10 during movement. During the process, the return spring 9 will be compressed and retracted. After the insertion rod 11 is removed from the first insertion hole 6, the insertion plate 13 is inserted into the insertion slot 5. When the fixing rod 12 is in the mounting hole of the car underbody protection plate, the handle 15 can be released, and the retracted return spring 9 will extend, allowing the insertion rod 11 to be inserted into the first insertion hole 6 again. The insertion rod 11 will also be inserted into the second insertion hole 14, which can restrict the position of the insertion plate 13, so that the insertion plate 13 is stably placed in the insertion slot 5. This completes the connection between the base 3 and the docking plate 4 or between the docking plate 4 and another docking plate 4, ensuring the stability of the connection and preventing the underbody protection plate from falling off due to external force during the inspection or processing.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
