[0027] Application Overview

[0028] The existing bolts only have the function of connecting two parts and cannot collect metal debris in the engine oil.

[0029] Based on the above technical problems, the present application proposes a connecting bolt for an engine, wherein the connecting bolt for the engine has a simple structure, does not involve complicated manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the connecting bolt for the engine provided by the present application is easy to produce and low in cost, which is more conducive to controlling production costs and further conducive to product promotion and use.

[0030] Schematic diagram of the connecting bolts on the engine.

[0031] refer to Figure 1 to Figure 2 According to a preferred embodiment of the utility model, a connecting bolt for an engine is provided on an engine cylinder block, and includes a bolt body 10, one end of the bolt body 10 has a threaded portion 101, the end of the threaded portion 101 is provided with a magnet installation groove 1011, and a magnetic member 20 is provided in the magnet installation groove 1011. It should be noted that in the embodiment of the present application, a cross section of the magnet installation groove 1011 is circular, and the magnetic member 20 is a magnet.

[0032] It should also be noted that, by providing the magnetic member 20 at the end of the threaded portion 101, when the connecting bolt for the engine is screwed into the oil storage chamber in the engine, when the oil in the oil storage chamber is mixed with metal debris, the metal debris will be adsorbed by the magnetic member 20, thereby avoiding the risk of metal debris flowing to other components along with the engine oil, and effectively reducing the overall wear of the engine; in addition, by arranging the magnetic member 20 on the connecting bolt for the engine, during regular maintenance, the maintenance personnel only need to unscrew the connecting bolt for the engine and clean the metal debris adsorbed on the magnetic member 20. Compared with the need to remove the oil pan to clean the entire oil storage chamber, it has the advantage of being more convenient to remove the metal debris, which is also an important reason for arranging the magnetic member 20 on the threaded portion 101. It is obvious that compared with the bolts that only have a connecting function in the prior art, the embodiment of the present application has the advantage of being able to collect metal debris.

[0033] Furthermore, a space is provided for accommodating the adsorbed metal debris, such as Figure 1 As shown, one end of the magnetic member 20 away from the bottom wall of the magnet installation slot 1011 is spaced a predetermined distance from the slot opening of the magnet installation slot 1011 .

[0034] Furthermore, in order to realize the connection between the magnetic component 20 and the bolt body 10 , one end of the magnetic component 20 close to the bottom wall of the magnet installation groove 1011 is bonded and connected to the bottom wall of the magnet installation groove 1011 .

[0035] More specifically, during installation, the installer applies metal glue on one side of the magnetic part 20 close to the bottom wall of the installation groove, presses the magnetic part 20 into the magnet installation groove 1011, and after the metal glue solidifies, the connection between the magnetic part 20 and the bolt body 10 is achieved.

[0036] Furthermore, in order to prevent the magnetic member 20 from bearing torque at the bonding point with the bottom wall of the installation groove, as shown in FIG. Figure 1 and Figure 2 As shown, the groove surface of the magnet mounting groove 1011 has a plurality of protrusions 10111 arranged in a ring shape, and the magnetic component 20 has a plurality of grooves 201 arranged in a ring shape in the circumferential direction. When the magnetic component 20 is placed in the magnet mounting groove 1011, the protrusions 10111 are inserted into the grooves 201.

[0037] More specifically, in order to prevent the metal glue from overflowing the slot of the magnet installation slot 1011, as Figure 1As shown, each of the protrusions 10111 extends a predetermined distance from the bottom wall of the magnet mounting groove 1011 toward the slot opening of the magnet mounting groove 1011, and is spaced a predetermined distance from the slot opening of the magnet mounting groove 1011. An end face of each of the grooves 201 on the magnetic member 20 close to the slot opening of the magnet mounting groove 1011 is spaced a predetermined distance from the slot opening of the magnet mounting groove 1011.

[0038] It should also be pointed out that, by providing the protrusion 10111 and the groove 201, the overflowing glue can fill the gap between the protrusion 10111 and the groove 201, thereby increasing the overall bonding area.

[0039] Furthermore, if Figure 1 As shown, the magnetic part 20 has a glue overflow hole 202 at one end close to the bottom wall of the magnet mounting groove 1011. The glue overflow hole 202 is a countersunk hole. The glue overflow hole 202 is located at the center of the magnetic part 20. By setting the glue overflow hole 202, the risk of metal glue overflowing during assembly is further reduced.

[0040] Furthermore, if Figure 1 As shown, the end of the bolt body 10 away from the threaded portion 101 has a nut portion 102, and the maximum radial dimension of the nut portion 102 is greater than the maximum radial dimension of the threaded portion 101. When the threaded portion 101 is screwed in a predetermined distance, it abuts against the external oil pan through the nut portion 102.

[0041] Furthermore, in order to facilitate the circumferential rotation of the bolt body 10, Figure 1 As shown, the bolt body 10 further has a screw hole 103 , and the screw hole 103 extends from the nut portion 102 toward the threaded portion 101 by a predetermined distance. A cross section of the screw hole 103 is preferably a square hole or a regular hexagonal hole.

[0042] Furthermore, if Figure 1 As shown, the connecting bolt used on the engine further includes a gasket 30 , and the gasket 30 is located at one end of the nut portion 102 close to the threaded portion 101 .

[0043] Furthermore, if Figure 1 As shown, the end of the threaded portion 101 away from the nut portion 102 is arranged with a reduced diameter, that is, the maximum radial dimension of the end of the threaded portion 101 away from the nut portion 102 is smaller than the maximum radial dimension of the end of the threaded portion 101 close to the threaded portion 101, so that the threaded portion 101 can be screwed into the external threaded hole.

[0044] In summary, the connecting bolt for the engine based on the embodiment of the present application is explained, which provides the connecting bolt for the engine with advantages such as being able to collect metal debris and facilitate the removal of metal debris.

[0045] It is worth mentioning that in the embodiment of the present application, the connecting bolts used on the engine have a simple structure, do not involve complex manufacturing processes and expensive materials, and have high economic efficiency. At the same time, for manufacturers, the connecting bolts used on the engine provided by the present application are easy to produce and have low cost, which is more conducive to controlling production costs and further conducive to product promotion and use.
