DETAILED DESCRIPTION

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] Please also read Figures 1 to 7 The emergency stop button protective cover structure provided by the utility model is now described. The emergency stop button protective cover structure comprises a shell 1, a flip cover 2, a buckle structure 3 and an elastic opening structure 4. The shell 1 is used to place the emergency stop button 5; one side of the shell 1 is an opening surface 11; the flip cover 2 is hinged to the shell 1 and is used to block the opening surface 11; the buckle structure 3 comprises a first buckle 31 arranged on the shell 1, and a second buckle 32 arranged on the flip cover 2; the elastic opening structure 4 is arranged between the flip cover 2 and the shell 1.

[0037] When the second buckle 32 is buckled with the first buckle 31, the flip cover 2 is in a closed state, and the elastic opening structure 4 stores energy. Figure 4 and Figure 5 When the second buckle 32 is separated from the first buckle 31, the elastic opening structure 4 releases energy to flip the flip cover 2 to the open state, such as Figure 1 and Figure 2 shown.

[0038] The housing 1 is disposed on the outside of the emergency stop button 5, and the button portion of the emergency stop button 5 is located inside the housing 1 and faces the opening surface 11. One end of the emergency stop button 5 passes through the housing 1 and is electrically connected to the device.

[0039] The flip cover 2 is hinged to the housing 1 , and the flip cover 2 can swing along the hinge axis so that the flip cover 2 can be opened and closed.

[0040] The first buckle 31 is arranged on the housing 1, and can be arranged on the opening surface 11 or on the outer peripheral surface. The second buckle 32 is arranged on the flip cover 2, and can be located inside the flip cover 2 or on the outer peripheral surface of the flip cover 2. The first buckle 31 and the second buckle 32 can be fastened together and can also be separated.

[0041] The first buckle 31 and the second buckle 32 both have hook parts, and the two hook parts are hooked to each other to form a buckle. Figure 7 As shown. Without the action of external human force, the hooking state of the second buckle 32 and the first buckle 31 can ensure the stable closing of the flip cover 2. When the flip cover 2 is manually moved, the buckling force between the first buckle 31 and the second buckle 32 can be overcome, and the second buckle 32 swings with the flip cover 2 and disengages from the first buckle 31.

[0042] The elastic opening structure 4 is arranged between the flip cover 2 and the housing 1. The elastic opening structure 4 can be a torsion elastic member or a linear elastic member. If it is a torsion elastic member, it is preferably arranged at the hinged part of the flip cover 2 and the housing 1. If it is a linear elastic member, it is preferably close to the buckle structure 3. The elastic opening structure 4 stores energy when the flip cover 2 is in the closed state. When the flip cover 2 is manually pulled to disengage the second buckle 32 from the first buckle 31, the elastic opening structure 4 releases energy to elastically open the flip cover 2. After the energy of the elastic opening structure 4 is completely released, it can also support the flip cover 2 to make the flip cover 2 stable when it is in the open state.

[0043] Compared with the prior art, the emergency stop button protection cover structure provided by the utility model has a shell 1 and a flip cover 2 to enclose a cavity for blocking the emergency stop button 5, so that the emergency stop button 5 is prevented from being exposed to the outside, accidental touching is eliminated, and the service life is extended; the flip cover 2 is hinged to the shell 1, and the snap-fit ​​structure 3 can ensure that the flip cover 2 is in a stable closed state; when an emergency stop operation is required, it is only necessary to manually release the snap-fit ​​connection between the second snap 32 and the first snap 31, and the flip cover 2 is flipped open under the action of the elastic opening structure 4, so that it can be in a stable open state, will not swing at will, and will not affect the operation of pressing the emergency stop button, thereby improving the convenience and reliability of the emergency stop operation.

[0044] In some embodiments, the elastic opening structure 4 can be used as follows: Figure 3 , Figure 6 and Fig.10 The structure shown, see Figure 3 , Figure 6 and Fig.10 The elastic opening structure 4 includes a torsion elastic member, which is arranged at the hinged portion between the flip cover 2 and the housing 1 , and the first end of the torsion elastic member is connected to the housing 1 , and the second end is connected to the flip cover 2 .

[0045] The torsion elastic member stores energy by torsion, has a simple structure, is arranged at the hinged portion between the flip cover 2 and the housing 1, and can be assembled with the aid of a hinge shaft. Compared with a linear elastic member, it does not need to be arranged on the opening surface 11 and occupies less space.

[0046] In addition, after the energy of the torsion elastic member is completely released, it is difficult to automatically twist and store energy without the action of external artificial force. That is to say, without the action of external artificial force, the torsion elastic member can stabilize the flip cover 2 in the open state, preventing the flip cover 2 from shaking randomly after opening and affecting the emergency stop operation.

[0047] In some embodiments, the hinged portion between the flip cover 2 and the housing 1 may be formed as follows: Figure 1 and Figure 4 The structure shown, see Figure 1 and Figure 4 Two connecting ears 12 are provided on the opening surface 11; a connecting block 21 is provided on the outer circumferential surface of the flip cover 2; the connecting block 21 is located between the two connecting ears 12 and is hinged to the two connecting ears 12 through a rotating shaft 23; the torsion elastic member is sleeved on the rotating shaft 23.

[0048] Specifically, the connecting ear 12 protrudes radially outward from the housing 1. The connecting block 21 is disposed on the outer peripheral surface of the flip cover 2 and can be integrally formed with the flip cover 2 or separately disposed on the flip cover 2. The rotating shaft 23 can be understood as a hinge shaft between the flip cover 2 and the housing 1.

[0049] The flip cover 2 and the housing 1 are hinged via a connecting block 21 and two connecting ears 12 , and the connecting block 21 is located between the two connecting ears 12 , which can ensure that the connecting block 21 is subjected to balanced force when rotating.

[0050] The torsion elastic member is sleeved on the rotating shaft 23 and can be fixed and force stored by means of the rotating shaft 23, which is convenient for assembly; and the torsion elastic member and the rotating shaft 23 can be fixed at the same time, saving space.

[0051] In order to stabilize the state between the two connecting ears 12 and prevent relative errors, a reinforcing plate may be provided between the two connecting ears 12 . The reinforcing plate should avoid the connecting block 21 to avoid interference with the connecting block 21 .

[0052] In some embodiments, the connection block 21 may be configured as follows: Fig.10 The structure shown, see Fig.10 The connecting block 21 has a receiving cavity 213 and a limiting groove 214 communicating with the receiving cavity 213 . The torsion elastic member and the rotating shaft 23 are located in the receiving cavity 213 , and the second end of the torsion elastic member is embedded in the limiting groove 214 .

[0053] The accommodating cavity 213 is used to limit the torsion elastic member, which is convenient for assembling the torsion elastic member and can ensure the stability of the torsion energy storage state of the torsion elastic member. The limiting groove 214 is used to limit the second end of the torsion elastic member. The groove width of the limiting groove 214 is adapted to the end diameter of the torsion elastic member to form a snap connection, so that the torsion elastic member is connected to the connecting block 21.

[0054] Preferably, the accommodating cavity 213 passes through both ends of the connecting block 21 , that is, the accommodating cavity 213 is a through cavity.

[0055] See also Fig.10 On the basis of the above embodiment, a notch 215 is provided on the connecting block 21 , and the first end of the torsion elastic member extends out of the notch 215 .

[0056] The second end of the torsion elastic member extends into the limiting groove 214 and is fixed, and the first end needs to be fixed to the connecting ear 12 or the housing 1. Since the connecting block 21 is almost in contact with the connecting ear 12, the distance between the two is very small. In order to facilitate the fixation of the first end of the torsion elastic member, a notch 215 is provided on the connecting block 21, and the first end extends from the notch 215, so that the first end is connected to the housing 1.

[0057] Preferably, the first end of the torsion elastic member may not be directly connected to the housing 1 and is a free end. Specifically, in the closed state, the first end of the torsion elastic member abuts against the opening surface 11, and in the open state, the first end of the torsion elastic member is separated from the opening surface 11.

[0058] Since the first end does not need to be directly connected to the housing 1 but is connected by abutment and limiting means, the installation of the torsion elastic member can be simplified.

[0059] In some embodiments, the flip cover 2 may also be used as follows: Figure 3 , Figure 6 and Fig.10 The structure shown, see Figure 3 , Figure 6 and Fig.10 A positioning structure 22 is also provided on the radial outer end surface of the connecting block 21. The positioning structure 22 has an abutting surface. When the flip cover 2 is in the normally closed state, the positioning structure 22 is away from the opening surface 11. When the second buckle 32 is manually overcome to hook with the first buckle 31, after the flip cover 2 swings, the abutting surface of the positioning structure 22 abuts against the opening surface 11.

[0060] The positioning structure 22 is added to the connection block 21 to further increase the stability of the flip cover 2 in the open state. Since the positioning structure 22 abuts against the opening surface 11 along the axial direction of the housing 1, a limit is formed in the rotation direction of the flip cover 2. Even if the artificial external force is removed, the flip cover 2 can maintain a stable open positioning state, so that the operator's hands are freed and the operator can focus on the emergency stop operation of the emergency stop button 5, thereby increasing the reliability and convenience of the emergency stop operation.

[0061] The axial direction of the flip cover 2 is defined as a first direction, and the positioning structure 22 extends toward the inner side of the flip cover 2 along the first direction; when the flip cover 2 is in a closed state, the positioning structure 22 is located at the radial periphery of the opening surface 11 .

[0062] Specifically, the positioning structure 22 can be regarded as a strip-shaped block structure, formed on the radial outer end surface of the connecting block 21, and slightly protruding toward the inner side of the flip cover 2. The abutting surface of the positioning structure 22 can be regarded as the inner edge of the radial outer end surface of the connecting block 21.

[0063] When the flip cover 2 is in the normally closed state, the positioning structure 22 is located at the radial periphery of the opening surface 11. Figure 6 As shown, when the flip cover 2 is flipped from the closed state to the open and positioned state, the positioning structure 22 passes through the outer peripheral surface of the housing 1 .

[0064] Preferably, the hinged portion between the connecting ear 12 and the connecting block 21 is located at the radial periphery of the opening surface 11. On the one hand, when the flip cover 2 swings, the hinged portion will not interfere with the movement trajectory of the positioning structure 22, and it is ensured that only the positioning structure 22 abuts against the opening surface 11, thereby reducing the friction contact area between the radial outer end surface of the connecting block 21 and the opening surface 11, that is, reducing the external resistance to manually opening the flip cover 2; on the other hand, the flip cover 2 will not interfere with the opening surface 11.

[0065] The inner surface of the connecting block 21 has a contact plane 211 and an outer convex arc surface 212 connected in sequence. Figure 3 , Figure 6 and Fig.10 As shown; the abutment plane 211 is flush with the inner end surface of the flip cover 2; in the first direction, the convex arc surface 212 protrudes toward the inner side of the flip cover 2 relative to the abutment plane 211.

[0066] When the flip cover 2 is in a closed state, the abutting plane 211 abuts against the opening surface 11 , and the convex arc surface 212 is located radially outside the opening surface 11 ; when the flip cover 2 is flipped over, the convex arc surface 212 passes through the outer peripheral surface of the housing 1 .

[0067] The inner surface of the connecting block 21 can be divided into two parts, one part is the abutting plane 211, which is smoothly connected and flush with the inner end surface of the flip cover 2, and the other part is the convex arc surface 212. Since the convex arc surface 212 protrudes toward the inner side of the flip cover 2 relative to the abutting plane 211, whether the flip cover 2 is opened or closed, during the flipping process of the flip cover 2, the convex arc surface 212 will pass through the outer peripheral surface of the shell 1, and generate rotational friction and extrusion between the shell 1, which plays a role in reminding the operator of the rotation position of the flip cover 2, especially the opening position of the flip cover 2.

[0068] Preferably, see FIG. Figure 3 , Figure 6 and Figure 8 The outer peripheral surface of the housing 1 has an arc-shaped transition surface 13 ; when the flip cover 2 is turned over, the outer convex arc surface 212 passes through the arc-shaped transition surface 13 .

[0069] The arcuate transition surface 13 can be understood as a rounded transition between the opening surface 11 and the outer peripheral surface of the housing 1 . The arcuate transition surface 13 does not need to be arranged around the outer periphery of the housing 1 , but only needs to correspond to the connecting block 21 in the circumferential direction.

[0070] The arc transition surface 13 and the outer convex arc surface 212 are both arc surfaces, so that when the outer convex arc surface 212 passes through the arc transition surface 13, there is always a line contact between the two, thereby reducing the mutual friction between the two and reducing wear and deformation.

[0071] In some embodiments, the position of the second buckle 32 can be as follows: Figure 2 , Figure 5 and Figure 7 The structure shown, see Figure 2 , Figure 5 and Figure 7 The second buckle 32 is arranged on the inner circumference of the flip cover 2 .

[0072] The second buckle 32 is arranged on the inner circumference of the flip cover 2, so that the second buckle 32 can be shielded by the flip cover 2 after being buckled with the first buckle 31, thereby preventing the buckling structure 3 from being exposed to the outside and causing collision and wear to affect the buckling stability.

[0073] In some embodiments, the position of the first buckle 31 can be as follows: Figure 5 and Figure 8 The structure shown, see Figure 5 and Figure 8 , the first buckle 31 is arranged on the opening surface 11 .

[0074] The first buckle 31 is arranged on the opening surface 11, rather than on the outer circumference of the housing 1, that is, the buckle structure 3 does not occupy additional space, and is integrated inside the flip cover 2 and on the opening surface 11. In addition, the outer diameter of the flip cover 2 can be reduced accordingly, and the flip cover 2 only needs to be buckled on the opening surface 11, and does not need to expand beyond the outer circumference of the housing 1, thereby meeting the hinge requirements with the housing 1.

[0075] Since the buckle structure 3 is integrated in the interior of the flip cover 2 and the opening surface 11, and the flip cover 2 is buckled on the opening surface 11, in order to facilitate the operator to open the flip cover 2 with less effort, please refer to Figure 1 , Figure 4 On the basis of the above-mentioned embodiment, the outer peripheral surface of the flip cover 2 has an inwardly recessed hand-clasp cavity 24 , and the hand-clasp cavity 24 corresponds to the second buckle 32 inwardly and radially of the flip cover 2 .

[0076] When opening the flip cover 2 , the operator can place the finger in the hand cavity 24 and then apply force to flip the flip cover 2 , so that the operator can open the flip cover 2 with less effort.

[0077] Preferably, the hinged portion of the hand cavity 24 and the flip cover 2 are located on the same radial line of the flip cover 2 .

[0078] In some embodiments, the housing 1 may also be Figure 8 The structure shown, see Figure 8 A sleeve 14 is provided inside the shell 1 , and a reinforcing rib group 15 is provided between the inner wall of the shell 1 and the outer wall of the sleeve 14 ; the inner cavity of the sleeve 14 forms a limiting cavity of the limiting emergency stop button 5 .

[0079] A step surface is provided inside the limiting cavity, and the outer periphery of the emergency stop button 5 abuts against the step surface, and one end of the emergency stop button 5 extends out of the sleeve 14. Figure 2 and Figure 5 The sleeve 14 serves as a limit to prevent the housing 1 from shaking significantly relative to the emergency stop button 5 and touching the button portion of the emergency stop button 5 .

[0080] In addition, a reinforcing rib group 15 is provided between the outer wall of the sleeve 14 and the inner wall of the outer shell 1 . The reinforcing rib group 15 includes a plurality of reinforcing ribs equally spaced along the circumferential direction. The reinforcing rib group 15 is used to improve the overall strength of the outer shell 1 .

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
