Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflicting with each other.

An engine valve chamber cover structure as shown in fig. 1-4, including lid 1, be provided with a plurality of ignition hole 2 on the lid 1 and along the fixed slot 3 that lid 1 edge and ignition hole 2 edge set up, fixed slot 3 includes bolt through-hole 31 and with bolt spare 4 of bolt through-hole 31 cooperation installation, bolt spare 4 includes screw 41 and check spring 42, the cooperation of screw 41 is provided with prevents falling ring 43, screw 41 runs through bolt through-hole 31 connection on the lid 1 and prevents falling ring 43, one side of lid 1 orientation engine is provided with seal groove 10, fixed slot 3 evenly sets up along seal groove 10, and is provided with the sealing plug pad that is located between lid 1 and the engine in the seal groove 10, the sealing plug pad is fixed in seal groove 10 through 3M glue.

As a further arrangement of the above scheme, the ignition hole 2 is of a square structure, four corners of the ignition hole are provided with fixing grooves 3, and one side surface facing the engine is provided with a sealing groove 10.

As a further provision of the above solution, the inner ring of the anti-drop ring 43 is also provided with a thread opposite to the engine threaded hole.

As a further arrangement of the above solution, the diameter of the bolt through hole 31 is larger than that of the anti-loose spring 42, and the screw 41 includes a threaded section 411 and a non-threaded section 412.

As a further arrangement of the above scheme, the screw 41 has a nut 45 attached to the cover body 1, and two ends of the anti-loose spring 42 are respectively provided with an arrangement for being adsorbed on the nut 45 and the anti-drop ring 43

The utility model discloses a valve chamber cap passes through bolt spare 4 fixed back, compresses tightly the sealing plug pad and forms relative sealed space, makes valve chamber cap in normal use state through setting up bolt spare 4, and sealing performance does not receive the influence, and its bolt spare 4 can not produce not hard up problem because of engine and external force vibrations, based on bolt spare 4 spring and have the structure setting of non-screw section when dismantling the valve chamber cap, also can avoid breaking away from of bolt spare 4 subassemblies and drop, just the 4 simple structure convenient to use of bolt spare of the utility model.

The valve chamber cover of the utility model has the advantages that the anti-loose spring 42 is firstly sleeved with the bolt 41 when the bolt piece 4 is installed, so that the magnetic ring 421 is absorbed on the nut 45, then the anti-falling ring 43 is placed at the bolt through hole 31 at one side of the cover body 1, then the bolt 41 is arranged through the bolt through hole 31, based on the internal thread of the anti-falling ring 43, the anti-falling ring 43 enters the non-thread section 412 through the thread section 411, at the moment, the anti-falling ring 43 is in non-thread fit with the bolt 41, therefore, the axial movement can be carried out, the magnetic ring 421 at the other end can be absorbed on the anti-falling ring 43 by pushing the anti-falling ring 43, when the valve chamber cover is fixed on the engine, the thread section 411 is matched with the threaded hole of the engine, the anti-falling ring 43 is always in the non-thread section 412 under the spring tension, the screw 41 gradually enters the threaded hole of the engine in a rotating manner, meanwhile, the anti-falling ring 43 is pushed to move axially until clinging to the cover body 1, meanwhile, the anti-falling ring 43 without the screw section 412 is positioned, based on the pulling force of the anti-loosening spring 42, the anti-falling ring 43 cannot exit the screw 41 along the threads, based on the non-fixed setting of magnetic adsorption, the rotation of the screw 41 cannot cause the circumferential deformation of the anti-loosening spring 42, and in two states, during fastening and dismounting, the pulling force of the anti-falling ring 43 and the elastic resetting jacking force during fixing are achieved through the anti-loosening spring 42, the anti-falling and anti-loosening design effect is formed, when the fixing is effectively achieved, the problem that the screw is subjected to external force and the loosening caused by engine vibration is solved, and when the cover body 1 is dismounted, the screw 41 falls off relative to the cover body 1 and falls into the gap of the engine.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
