Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to improvement of a maintenance lid attached to a shield plate that covers the outer periphery of an engine of a large vehicle.

(Prior Art) Conventionally, an engine of a large vehicle is provided with a shielding plate so as to cover the outer periphery of the engine for the purpose of soundproofing, etc., and an oil filter or a fuel filter directly attached to the engine is attached to the shielding plate. In order to attach / detach, etc., an opening is provided at a position corresponding to the oil filter, the fuel filter, etc., and a metal maintenance lid which is detachable by screwing a thumbscrew or the like is attached. .

(Problems to be solved by the invention) However, in the above-mentioned conventional one, when an opening is provided in a shielding plate that covers the outer periphery of an engine and a maintenance lid that is removable by screwing a thumbscrew or the like is attached, In order to perform maintenance of filters, etc., the thumbscrews that fix the maintenance lid must be removed, which is very troublesome for the maintenance person, and the metal maintenance lid is fixed to the shield plate. By repeatedly attaching and detaching the thumbscrew, etc., the screwing with the shield plate becomes unsatisfactory and the prescribed tightening force cannot be generated, or the screwing is securely performed by the operator's carelessness. Otherwise, the vehicle may resonate with the vibration generated by the vehicle while driving, causing rattling due to the collision with the shield plate and dropping of the maintenance lid due to the drop of the thumbscrew fixing the maintenance lid. The soundproofing effect on gin is likely to decrease.

For this reason, an engine undercover consisting of a sound-insulating member, which is fixed to the support frame and which has one end fixed with a bolt and the other end to which a magnet is attached, is attached to a flange that is provided with openings at the top and bottom. 57-18
No. 2569) has been proposed, but since a magnet is used to close the opening drilled in the flange, detachment easily occurs due to vibration, etc., causing noise and fixing to the flange. Since one end of the oil filter is fixed by screwing a bolt, there is a drawback that the maintainability of the oil filter or the like cannot be sufficiently improved.

Therefore, this invention is intended to improve the drawbacks of the above conventional ones, and to open and close the maintenance lid provided on the shield plate in order to ensure maintainability.

(Means for Solving the Problems) For that purpose, the upper end of a rectangular rubber-shaped maintenance lid having elasticity is fixed to the outer surface side upper edge of the maintenance opening of the shielding plate,
Further, one side end portion of the maintenance lid is engageably fixed by a free end of a locking plate that is fixed to one side edge of the shielding plate on the outer surface side of the maintenance opening and is openable and closable. It is a thing.

(Operation) With the above configuration, when the maintenance lid attached to the shield plate for maintenance is removed, the engagement between the side portion of the maintenance lid and the locking plate of the shield plate is released. ,
The upper portion of the maintenance lid is only fixed to the upper edge of the opening of the shield plate, and the maintenance lid is made of elastic rubber material. The opening can be exposed for maintenance, and when the opening of the shielding plate is to be closed, the maintenance lid that has been rolled up is lowered and fixed to the side edge of the opening. By engaging the free end of the locking plate with the maintenance lid, the shielding plate and the maintenance lid can be fixed by the maintenance lid closing the opening of the shielding plate.

(Embodiment) This invention will be further described in the embodiments shown in the drawings. (1) is a shield plate provided so as to cover the outer periphery of an engine, which comprises the embodiment of the present invention. The shield plate (1) is made of metal, and the shield plate (1) has a rear end ,
Oil filters etc. that are directly attached to the engine etc. (3)
The opening (2) is provided so as to correspond to the position (1), and the maintenance lid (4) is attached so as to normally close the opening (2).

The maintenance lid (4) is made of a rubber material having elasticity, and its upper portion (5) is fixed to the upper edge (2 ′) of the opening (2) by a plurality of clips (8), and the side lid is A crocodile clip (9) which is a locking plate that is fixed to the side edge (2 ″) of the opening (2) and is provided with a spring (10) in a long hole (7) provided in the vertical direction in the portion (6). ) Is fixed by opening and closing by fitting the projecting edge (12) of the tip pressing portion (11).

Since this device has the above configuration, when the maintenance of the oil filter etc. which is directly attached to the engine is to be performed, the elasticity of the spring (10) having the crocodile clip (9) for fixing the maintenance lid (4) is built in. By pushing against the contact hole, a long hole (7) is formed in the side portion (6) of the maintenance lid (4) and a tip pressing portion (1) of the crocodile clip (9).
By removing the fitting from the projecting edge (12) of 1), the maintenance lid (4) has the upper edge (5) of the upper edge (2 ') of the opening (2) by a plurality of clips (8). Since the maintenance lid (4), which is made of a flexible rubber material, is rolled up to open the opening (2), the maintenance can be easily performed.

Further, when the maintenance lid (4) is to be closed after the completion of maintenance, the maintenance lid (4) that has been rolled up is lowered and the protrusion is placed on the pressing portion (11) at the tip of the crocodile clip (9). A spring built in the crocodile clip (9) serving as a locking plate by fitting the projecting edge (12) into the long hole (7) of the side portion (6) of the maintenance lid (4). Due to the elasticity of (10), it can be fixed integrally with the shield plate (1).

(Effects of the Invention) As described above, the workability at the time of maintenance can be improved by attaching the maintenance lid made of a rubber material to the opening of the shielding plate by the clip and fixing the lid openably and closably by the locking plate. In addition, since the maintenance lid is made of a flexible rubber material, it does not resonate with vibration during traveling and has an excellent effect of soundproof shielding.
