Description

TECHNICAL FIELD

[0001] The utility model belongs to motorcycle technical field, more specifically is a kind of bolt reminding mistake-proof structure. BACKGROUND

[0002] The conventional bolt is all using right helix's screwing mode, and user will tighten loosening with his conventional common sense when disassembling;And left helix bolt is used on motorcycle accessory, and the locking stability of special installation position is guaranteed by the application of left helix bolt.And left helix bolt needs to be marked, so as to remind the user to be operated to tighten loosening reversely, but because of the long-term use of motorcycle, surface may exist dust, wear, rust and other conditions, the original mark of left helix bolt is extremely easy to lose effect, so that user error disassembly will cause the damage of left helix bolt, affect normal maintenance efficiency. UTILITY MODEL CONTENTS

[0003] In view of the deficiencies in the prior art, the utility model aims at providing a bolt reminding mistake-proof structure, to provide the mark reminder of left helix bolt for user, to prevent user from wrong operation.

[0004] The utility model provides the following technical scheme: a kind of bolt reminding mistake-proof structure, including the bolt body with left helix thread, the outer end of bolt body is the head portion for the wrench clamping rotation, the outer end of head portion is detachably installed with a blocking piece, and the first mark with reminding function is arranged on the blocking piece.

[0005] As an improvement, the outer edge of the blocking piece has a plurality of positions larger than the outer diameter of the head portion, thereby preventing the wrench from cooperating with the head portion.

[0006] As an improvement, the outer end of the head portion is provided with a second mark with a reminding function, and the second mark is blocked when the blocking piece is installed on the outer end of the head portion.

[0007] As an improvement, the blocking piece is connected to the outer end of the head portion by insertion, clamping or screwing.

[0008] As an improvement, the blocking piece is detachably installed on the outer end of the head portion by a screw, and the head portion is provided with a screw hole matched with the screw.

[0009] As an improvement, a gasket is provided between the screw and the blocking piece.

[0010] The utility model discloses beneficial effect: by the blocking of blocking piece prevents operator directly dismounts bolt body, through the observation first mark on blocking piece can remind operator bolt body is left helical structure, and then play the function effect of mistake proofing, operator can normally dismount bolt body after dismounting blocking piece, and the whole does not improve the dismounting complexity, also plays the effective protection and the mistake proofing of bolt. BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1 It is the three-dimensional structure schematic diagram of the utility model.

[0012] Figure 2 It is the three-dimensional structure explosion schematic diagram of the utility model. DETAILED DESCRIPTION

[0013] The following detailed description of the specific embodiment of the utility model is made in combination with the drawings.

[0014] As Figure 1 , 2 The embodiment includes bolt body 1 with left helical thread, the outer end of bolt body 1 is the head 11 for the clamping rotation of spanner, the outer end detachable mounting of head 11 has a blocking piece 2, and the first mark 21 with reminding function is arranged on blocking piece 2.

[0015] The utility model in use, bolt body 1 installs, and its head 11 adds a detachable blocking piece 2, on the one hand, this blocking piece 2 is blocked by structure and makes operator use spanner unable to directly dismount bolt body 1, and then needs to dismount blocking piece 2 first, and the first mark 21 on blocking piece 2 shows an intuitive reminding mode as shown in the figure, that is, the obvious bolt is in which direction, and the specific reminding can be the separate or combined use of english expression, Chinese mark, arrow mark, so that the operator dismounts the bolt according to the prompt, and then plays the function effect of mistake proofing, and effectively protects the bolt.

[0016] As an improved specific embodiment, the outer edge of blocking piece 2 has multiple positions greater than the outer diameter of head 11, so that blocking piece 2 blocks the cooperation of spanner and head 11.

[0017] As Figure 1 After the outer edge of blocking piece 2 has multiple positions greater than the outer diameter of head 11, the spanner cannot be directly clamped to head 11 for cooperation, and the operator needs to dismount blocking piece 2 first, so that the operator can notice the first mark 21 on blocking piece 2 when dismounting blocking piece 2, avoiding the careless operation of the operator.

[0018] As an improved specific embodiment, the outer end of the head 11 is provided with a second mark 12 with a reminding function, and the blocking piece 2 covers the second mark 12 when the blocking piece 2 is installed on the outer end of the head 11.

[0019] As shown in Figure 2 , the second mark 12 is similar to the first mark 21, and the bolt rotation direction can be indicated in various ways. The second mark 12 is covered by the blocking piece 2 that is installed, thereby achieving a certain protection effect, thereby reducing the possibility of the second mark 12 being covered and damaged by dust, wear, rust, and the like, thereby ensuring that the second mark 12 maintains its reminding and error prevention function.

[0020] As an improved specific embodiment, the blocking piece 2 is inserted, clamped, or threaded onto the outer end of the head 11.

[0021] In a specific embodiment, the blocking piece 2 can be disassembled by the above prior art, which ensures the stability of the blocking piece 2 installed on the head 11.

[0022] As an improved specific embodiment, the blocking piece 2 is detachably installed on the outer end of the head 11 by a screw 3, and the head 11 is provided with a screw hole 13 matched with the screw 3.

[0023] As shown in Figure 1 , 2 , as preferred, the blocking piece 2 is installed by the screw 3, and after the screw 3 is installed in the screw hole 13, it needs to be disassembled by a tool, thereby improving the stability of the installation of the blocking piece 2. As shown in the figure, the screw 3 adopts a hexagonal hole, which needs the operator to use a hexagonal wrench of the corresponding specification to disassemble. Similarly, the head 11 is a hexagonal structure, which needs a hexagonal wrench of the corresponding specification to disassemble.

[0024] As an improved specific embodiment, a gasket 4 is provided between the screw 3 and the blocking piece 2.

[0025] As shown in Figure 1 , 2 , the additional gasket 4 can ensure that the screw 3 is installed more stably, and the screw 3 is not easy to loosen due to the vibration of the motorcycle.

[0026] The above is only a preferred embodiment of the present application, and the protection scope of the present application is not limited to the above embodiments. Any technical solution that belongs to the idea of the present application is within the protection scope of the present application. It should be noted that for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principle of the present application are also considered as the protection scope of the present application.
