Description

Technical Field

[0001] This utility model relates to the field of robot accessories technology, and in particular to a waterproof cover for an explosion-proof emergency stop button. Background Technology

[0002] Petrochemical pipelines are characterized by numerous points of operation, long distances, high pressure, flammability, explosiveness, and potential for environmental pollution. Therefore, if any abnormalities are not detected and handled promptly, they can not only jeopardize the normal operation of the pipeline but also threaten the lives and property of people along the route and the ecological environment. To strengthen the safety management of oil transfer stations, personnel are required to conduct regular inspections. However, manual inspections are labor-intensive, inefficient, and lack effectiveness. Robots are typically used to assist or replace manual inspections, minimizing the workload of frontline staff.

[0003] To ensure robots can operate in high-risk environments, explosion-proof emergency stop buttons are incorporated into their design. For example, patent application CN201710588039.3, entitled "An Explosion-Proof Inspection Robot," illustrates this feature. The emergency stop button functions as a power switch for the robot. To use it, the button is pressed to brake and rotated to unlock, a process identical to that of other emergency stop buttons currently on the market.

[0004] Due to the operating environment of robots, emergency stop buttons require good waterproofing. The emergency stop button in the aforementioned patent mainly utilizes a sealing ring between the button rod and the main cavity. Since the sealing ring is usually made of rubber, which has high friction, the button rod needs to move up and down while also rotating and resetting. This method is inconvenient for the use of the button rod. Therefore, it is necessary to provide a waterproof sleeve suitable for emergency stop buttons. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a waterproof sleeve for an explosion-proof emergency stop button. Through the segmented design, the waterproof sleeve and the emergency stop button rod can be fitted together, and the button rod can be moved up and down, rotated and rotated back conveniently.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a waterproof sleeve for an explosion-proof emergency stop button, comprising a sleeve body made of elastic soft material and having an integral structure, with an opening at one end of the sleeve body, and the sleeve body including a fixing part, an upper and lower reset part, a transition part, a rotation reset part and a connecting part connected in sequence from its sealed end to its open end. The fixing part is used to be sleeved on the outside of the button cap of the explosion-proof emergency stop button and connected to the button cap; The upper and lower reset parts have a stacked structure that can deform radially along the sleeve body; The rotating reset part has a folding structure that can deform along the circumference of the sleeve body; The connecting part is set along the opening of the rotating reset part to fix the sleeve body to the button rod of the explosion-proof emergency stop button.

[0007] Compared with the prior art, the present invention has the following beneficial effects: Understandably, flexible and soft materials such as silicone and rubber can be used to facilitate the fitting of the entire sleeve onto the button lever. Since the emergency stop button lever has a button cap at the top for easy operation, the sleeve of this invention includes a fixing part that fits onto the button cap, achieving a secure positioning connection for the entire sleeve. The upper and lower reset parts connected to the fixing part are deformable stacked structures, with the deformation direction along the length of the button lever to facilitate its vertical movement. Different emergency stop buttons have different lengths and shapes of levers; therefore, this invention includes a transition part to ensure the sleeve can be adapted to different models of emergency stop button levers. The folding structure of the rotating reset part can deform circumferentially along the sleeve, facilitating button lever rotation and subsequent reset without affecting its operation. The connecting part has a tapered opening to ensure it fits snugly against the main cavity (or other external base), ensuring overall waterproofing.

[0008] The waterproof sleeve designed in this utility model can change the existing sealing connection method between the button rod and the main cavity of the emergency stop button. While ensuring the waterproof sealing effect, the upper and lower reset parts and the rotation reset part can also facilitate the movement and rotation of the button rod, making it more convenient to use.

[0009] Furthermore, the stacked structure includes at least one bellows tension ring, with each bellows tension ring arranged sequentially along the radial direction of the sleeve body, and the bellows tension rings connected sequentially or sequentially through multiple transition rings.

[0010] Furthermore, the folding structure includes multiple bent plates, each bent plate being a strip-shaped structure along the radial direction of the sleeve body, and each bent plate having two connecting sidewalls along its length. Multiple bent plates are connected sequentially along the circumference of the sleeve body and arranged in a ring, and the connecting sidewall of any bent plate is connected to the connecting sidewall of the adjacent bent plate, or Multiple bent plates are arranged in a ring around the circumference of the sleeve body, and the connecting sidewall of any bent plate is connected to the connecting sidewall of the adjacent bent plate by a connecting plate.

[0011] Furthermore, the transition section has a flared structure, with the small end of the transition section connected to the upper and lower reset sections, and the large end of the transition section connected to the rotary reset section.

[0012] Furthermore, the connection end between the fixing part and the upper and lower reset parts has a constricted structure. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] like Figure 1 , 2 As shown in Figures 3 and 4, a waterproof sleeve for an explosion-proof emergency stop button includes a sleeve body 100 made of elastic soft material and having an integral structure. One end of the sleeve body 100 is open. The sleeve body 100 includes a fixing part 110, an upper and lower reset part 120, a transition part 130, a rotation reset part 140, and a connecting part 150 connected in sequence from its closed end to its open end. The fixing part 110 is used to fit over the button cap 210 of the explosion-proof emergency stop button 200 and connect to the button cap 210. The upper and lower reset part 120 has a stacking structure that can be deformed radially along the sleeve body 100. The rotation reset part 140 has a folding structure that can be deformed circumferentially along the sleeve body 100. The connecting part 150 is provided to close along the rotation reset part 140 and is used to fix the sleeve body 100 to the button rod 220 of the explosion-proof emergency stop button 200.

[0017] Understandably, the flexible soft material can be silicone, rubber, etc., to facilitate the fitting of the entire sleeve body 100 onto the button rod 220. In this utility model, the sleeve body 100 is made entirely of transparent silicone material; however, for ease of display in the illustration, the sleeve body 100 is shown as opaque.

[0018] The fixing part 110 is sleeved on and fixed to the button cap 210. Based on the material of the entire sleeve body 100, the shape of the fixing part 110 can be set to have the same structure as the button cap 210, but slightly smaller, so that the fixing part 110 and the button cap 210 can be sleeved and fixed. Currently, the button cap 210 is fixed to the end of the button rod 220 and forms a T-shaped structure with the button rod 220. Therefore, as Figure 4 As shown, the bottom of the fixing plate of this utility model adopts a tapered structure 111 to achieve a tight fit between the fixing part 110 and the button cap 210.

[0019] After the fixing part 110 and the button cap 210 are connected, the position of the entire body 100 can be limited. Based on this, in order to facilitate the movement and rotation of the button lever 220, the upper and lower reset parts 120, the transition part 130 and the rotation reset part 140 can actually be arranged in sequence or connected in random order. However, considering the aesthetics of the product, the upper and lower reset parts 120, the transition part 130 and the rotation reset part 140 are arranged in sequence.

[0020] The upper and lower reset parts 120 primarily facilitate the movement of the button lever 220. Therefore, the upper and lower reset parts 120 have a stacking structure that is radially deformable along the sleeve body 100. The stacking structure can be implemented in various ways; as long as the length of the structure in the radial direction of the sleeve body 100 is variable, it can match the movement of the button lever 220. In this invention, the stacking structure includes at least one bellows tension ring 121, such as... Figure 1 , 2 As shown in Figures 3 and 4, the bellows tension ring 121 is actually a vertically arranged folded ring structure. Pulling both ends of the folded ring can change the length of the entire folded ring in the vertical direction, that is, change the radial length of the sleeve body 100. The number of bellows tension rings 121 can be set one or more according to the moving length of different button levers 220. When multiple bellows tension rings 121 are set, each bellows tension ring 121 is arranged sequentially along the radial direction of the sleeve body 100, and each bellows tension ring 121 is connected sequentially or sequentially through multiple transition rings 122. Figure 5 As shown, this is a stacked structure consisting of multiple bellows tension rings 121 connected in sequence, as... Figure 6 As shown, it is a stacked structure consisting of multiple (N) bellows stretching rings 121 and multiple (N-1) transition rings 122.

[0021] Different emergency stop buttons 200 have button levers 220 with different lengths and shapes. Therefore, this invention provides a transition section 130 so that the entire body 100 can be adapted to the button levers 220 of different models of emergency stop buttons 200. The transition section 130 can be a straight cylindrical structure, a frustum-shaped structure, etc., depending on the usage requirements. Figure 3 As shown, the button lever 220 of this utility model is a variable diameter lever structure with a small upper part, a large middle part, and a small lower part. For this purpose, the transition part 130 has a flared structure. The small end of the transition part 130 is connected to the upper and lower reset parts 120, and the large end of the transition part 130 is connected to the rotary reset part 140. The transition part 130 can be used in conjunction with the button lever 220 shown in the figure.

[0022] The folding structure of the rotating reset part 140 can deform circumferentially along the sleeve body 100, facilitating the rotation of the button lever 220 and its reset after rotation, without affecting the operation of the button lever 220. To achieve this purpose, the folding structure can be a spiral structure arranged circumferentially along the sleeve body 100. In this utility model, as... Figure 1 , 2 As shown in Figures 3 and 4, the folding structure includes multiple bent plates 141, each bent plate 141 being a strip-shaped structure along the radial direction of the sleeve body 100, and each bent plate 141 having two connecting sidewalls along its length direction, such as... Figure 7 As shown (the cross-section in the figure is entirely black), multiple bent plates 141 are sequentially connected along the circumference of the sleeve body 100 and arranged in a ring. The connecting sidewall of any bent plate 141 is connected to the connecting sidewall of an adjacent bent plate 141, or, as... Figure 8 As shown (the cross-section in the figure is entirely black), multiple bent plates 141 are arranged in a ring around the circumference of the sleeve body 100, and the connecting sidewall of any bent plate 141 is connected to the connecting sidewall of an adjacent bent plate 141 by a connecting plate 142. Based on the presence of the bent plates 141, the circumferential dimension of the sleeve body 100 can be changed. Therefore, multiple bent plates 141 can be connected sequentially to form a folded structure, or a connecting plate 142 can be placed between two adjacent bent plates 141 to form a folded structure.

[0023] The constricted design of the connecting part 150 is intended to allow the waterproof sleeve to be fitted onto the button rod 220, such as... Figure 4 As shown, the button rod 220 of the variable diameter rod structure of this utility model has its lower part extending into the structure below (which can be the main cavity or the connecting base of the emergency stop button 200). Based on the structural limitations of the lower middle part and the lower part, the connecting part 150 can be closed along the lower middle part toward the lower part of the button rod 220, and the sleeve body 100 can be fixed on the button rod 220 to prevent external parts from entering the entire interior of the emergency stop button 200 along the outer wall of the button rod 220 (such as model LA53).

[0024] The waterproof sleeve provided by this utility model can change the sealing connection method between the button rod 220 and the main cavity of the existing emergency stop button 200. While ensuring the waterproof sealing effect, the upper and lower reset parts 120 and the rotation reset part 140 can also facilitate the movement and rotation of the button rod 220, making it more convenient to use.
