Description

Technical Field

[0001] This utility model relates to the technical field of brakes, and in particular to a brake device. Background Technology

[0002] Currently, most equipment (such as doors, compressors, and winches) is equipped with a handle for opening or using the equipment. However, when these devices are closed, the handle lacks a protective device to prevent it from turning, which can lead to the equipment being accidentally started and causing unnecessary damage. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a braking device that can limit the rotation of the handle to achieve a braking effect and improve safety.

[0004] The braking device according to a first aspect of the present invention includes a base, a movable member, and a supporting member.

[0005] The base includes an abutting portion and a connecting portion connected together. The abutting portion is used to abut against the main body of the device. A movable member is connected to the connecting portion. The side of the abutting portion facing the movable member is spaced apart from the movable member along a first direction. The movable member can move relative to the connecting portion along the first direction to change the spaced distance. A holding member is connected to the side of the movable member opposite to the connecting portion and moves with the movable member along the first direction. The holding member is used to abut against the handle. The side of the holding member opposite to the movable member extends along the first direction to form a limiting portion. The limiting portion is used to restrict the rotation of the handle.

[0006] The damping device according to the embodiments of this utility model has at least the following beneficial effects: by moving the movable member relative to the connecting part to increase the distance between the abutting part and the movable member, the abutting part can abut against the main body of the device. Simultaneously, the supporting member also moves along the first direction with the movable member, causing the supporting member to abut against the handle. Since the abutting part abuts against the main body of the device, and the supporting member abuts against the handle, friction is generated between the abutting part and the main body of the device, and between the supporting member and the handle, thereby restricting the rotation of the handle. Furthermore, the supporting member also forms a limiting part along the first direction, which further restricts the rotation of the handle, thereby preventing the device from being accidentally opened.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0038] The following description, with reference to the accompanying drawings, describes a blocking device according to a first aspect of the present invention. This blocking device is used to prevent a handle from turning to start a device, which may be a door, a compressor, or a winch, etc. It should be noted that when the device is a door, the blocking device is installed inside the room. This blocking device is suitable for scenarios where turning the handle on the outside of the door also causes the handle on the inside of the room to turn, i.e., a double-handle door, thereby preventing the door from being opened from the outside. Furthermore, the blocking device can also prevent children from accidentally opening the door from inside the house. When the device is a compressor or winch, etc., which requires turning a handle to start, the blocking device is installed between the device body and the handle to prevent the handle from turning and thus prevent the device from being opened. For ease of understanding and description, the embodiments of the present invention are illustrated by way of one type (e.g., a door). It should be noted that in the embodiments of the present invention, the left-right direction is indicated as the first direction, and the up-down direction is indicated as the second direction.

[0039] This utility model embodiment provides a braking device 100 for preventing the rotation of a handle, wherein, see reference Figure 1 , Figure 2 and Figure 4 As shown, the base 110 includes a connecting portion 111 and a connecting portion 112 connected together. The connecting portion 111 abuts against the door body. A movable member 120 is connected to the connecting portion 112 on the side opposite to the connecting portion 111. The connecting portion 112 is disposed between the connecting portion 111 and the movable member 120 along a first direction. The side of the connecting portion 111 facing the movable member 120 is spaced apart from the movable member 120 along the first direction by a distance H, that is, there is a distance H between the connecting portion 111 and the movable member 120 in the left-right direction. The movable member 120 is connected to the connecting portion 112, and the movable member 120 can move relative to the connecting portion 112 along the first direction, thereby changing the distance H between the connecting portion 111 and the movable member 120. The abutment member 130 is used to abut against the handle. The abutment member 130 is connected to the side of the movable member 120 opposite to the connecting portion 112. When the movable member 120 moves to change the interval distance H, since the abutment member 130 is connected to the movable member 120, the abutment member 130 will also move along the first direction with the movable member 120 until the abutment portion 111 abuts against the door body and the abutment member 130 abuts against the handle 300. Only then will the movable member 120 stop moving relative to the connecting portion 112. The side of the abutment member 130 opposite to the movable member 120 extends along the first direction to form a limiting portion 133, which is used to limit the rotation of the handle 300.

[0040] Specifically, in one example, see Figures 1 to 6As shown, when the door needs to be rotated, the blocking device 100 is placed between the door and the handle 300. Then, by driving the movable member 120 to move relative to the connecting part 112, the distance H between the movable member 120 and the abutment part 111 is increased, so that the abutment part 111 can abut against the door. Since the abutment member 130 moves along the first direction with the movable member 120, the movable member 120 will continuously move relative to the connecting part 112 during the installation of the blocking device 100 until the abutment part 111 abuts against the door and the abutment member 130 abuts against the handle 300, thereby connecting and fixing the blocking device 100 between the door and the handle 300. At this time, the limiting part 133 will be located below the handle 300 and play a limiting role. Since the handle 300 is usually rotated downwards to unlock the lock and open the door. Therefore, in this embodiment, the limiting part 133 is located below the handle 300 and restricts the handle 300 in the rotation direction of the handle 300.

[0041] The damping device 100 of this embodiment increases the distance between the abutment portion 111 and the movable member 120 by moving the movable member 120 relative to the connecting portion 112, allowing the abutment portion 111 to abut against the device body 200. Simultaneously, the supporting member 130 moves along the first direction with the movable member 120, abutting against the handle 300. Because the abutment portion 111 abuts against the device body 200, and the supporting member 130 abuts against the handle 300, friction is generated between the abutment portion 111 and the device body 200, and between the supporting member 130 and the handle 300, thereby restricting the rotation of the handle 300. Furthermore, the supporting member 130 also has a limiting portion 133 along the first direction, which further restricts the rotation of the handle 300, thus preventing the device from being accidentally opened.

[0042] In some embodiments, see Figure 2 and Figure 4 As shown, the damping device 100 also includes an alarm function. The interior of the connecting portion 112 is a hollow structure, which defines a receiving cavity 1121. The receiving cavity 1121 is connected to the side of the connecting portion 112 facing the movable member 120, so that the receiving cavity 1121 communicates with the outside. The damping device 100 includes an alarm 140, which is connected to the connecting portion 112 and housed in the receiving cavity 1121.

[0043] Specifically, when someone outside the door turns the handle 300 to open the door, the base 110 of the blocking device 100 abuts against the door, and the abutment 130 abuts against the handle 300, thereby restricting the handle 300 from rotating to unlock the door and open the door. In this embodiment, the alarm 140 is a vibration alarm. When an outsider is unable to open the door and strikes the door or shakes the handle 300, the alarm 140 will sense the vibration generated by the door or the handle 300, thereby triggering the alarm to alert the people inside the room.

[0044] In some embodiments, the movable member 120 is slidably connected to the connecting portion 112, and the movable member 120 slides relative to the connecting portion 112 along a first direction, thereby changing the interval distance H between the movable member 120 and the abutment portion 111. Specifically, in one example, a sliding groove is provided on the outer wall surface of the connecting portion 112 along the first direction, and the movable member 120 is connected in the sliding groove. When it is necessary to change the interval distance H, the movable member 120 is slid to increase or decrease the interval distance H between the movable member 120 and the abutment portion 111 accordingly, thereby enabling the installation of the blocking device 100 onto the door or the removal of the blocking device 100 from the door.

[0045] In another embodiment, one-way teeth are provided on the outer wall surface of the connecting part 112, and the one-way teeth are spaced along the first direction on the outer wall surface of the connecting part 112. In this case, the structure of the connecting part 112 is similar to a ratchet mechanism, except that the teeth of the ratchet mechanism are arranged in a ring shape, while the teeth of the connecting part 112 are arranged along the first direction. An abutment block is detachably provided on the movable member 120. By abutting the abutment block against different one-way teeth, the movable member 120 can slide relative to the connecting part 112. Since the teeth are one-way teeth, the abutment block can only move in the same direction. In this embodiment, when the abutment block is connected to the one-way teeth, the abutment block can only move to the right along the first direction to increase the interval distance H. When it is necessary to reduce the interval distance H, the abutment block can be removed from the movable member 120. After the movable member 120 is placed in the designated position, the movable member 120 and the connecting part 112 are connected and fixed by the abutment block.

[0046] Alternatively, in some embodiments, the movable member 120 is rotatably connected to the connecting portion 112. The connecting portion 112 has a central axis, and the movable member 120 can rotate relative to the connecting portion 112 about the central axis, thereby changing the gap distance H between the movable member 120 and the abutment portion 111. Specifically, in one example, the movable member 120 and the connecting portion 112 are connected by threads, such as: an external thread is provided on the outer wall surface of the connecting portion 112, at least a portion of the movable member 120 is fitted onto the outer wall surface of the connecting portion 112, and the portion of the movable member 120 fitted onto the outer wall surface of the connecting portion 112 is provided with an internal thread. The movable member 120 and the connecting portion 112 achieve rotation through the engagement of the internal and external threads, thereby changing the gap distance H.

[0047] In other embodiments, the rotatable connection between the movable member 120 and the connecting portion 112 can also be achieved via a worm gear. Specifically, a worm gear is connected to the side of the connecting portion 112 facing the movable member 120, and the axis of the worm gear coincides with the central axis of the connecting portion 112. A worm gear is fitted onto the outer wall surface of the movable member 120, and the external teeth of the worm gear mesh with the worm gear. When the movable member 120 rotates relative to the connecting portion 112, the worm gear rotates around the worm gear, thereby changing the interval distance H.

[0048] In some embodiments, see Figures 2 to 4 As shown, the movable member 120 is recessed along a first direction on the side facing the abutment member 130 to form a groove structure 121, that is, the movable member 120 is recessed to the left to form the groove structure 121. At least a portion of the abutment member 130 is accommodated in the groove structure 121. When the abutment member 130 abuts against the handle 300, if the handle 300 on the outside of the door rotates, the handle 300 on the inside of the room will rotate accordingly, causing friction between the handle 300 and the abutment member 130. Under the action of friction, the abutment member 130 tends to move relative to the movable member 120. The groove structure 121 can limit the abutment member 130. When the abutment member 130 moves relative to the movable member 120, the inner wall of the groove structure 121 contacts the abutment member 130, thereby restricting the movement of the abutment member 130, thereby hindering the rotation of the handle 300.

[0049] Furthermore, the movable member 120 and the supporting member 130 are rotatably connected. When the movable member 120 rotates relative to the connecting portion 112 to change the interval distance H, the movable member 120 will also rotate relative to the supporting member 130. At this time, the supporting member 130 will move along the first direction due to the change in the interval distance H, but the supporting member 130 will not rotate with the movable member 120. Along the second direction, the length of the supporting member 130 accommodated in the groove structure 121 is less than the length of the groove structure 121. See reference. Figure 4From the shown perspective, in the vertical direction, the height of the abutment 130 located in the groove structure 121 is less than the height of the groove structure 121. Specifically, in this embodiment, the position of the limiting part 133 needs to be set below the handle 300 to restrict the rotation of the handle 300. Therefore, it is necessary to ensure that the abutment 130 does not rotate with the movable part 120, so that the limiting part 133 is always located below the handle 300 during the installation process. This prevents the position of the limiting part 133 from deviating after the blocking device 100 is installed, thus failing to prevent the handle 300 from rotating. Making the length of the abutment 130 less than the length of the groove structure 121 can reduce the contact between the outer wall of the abutment 130 and the inner wall of the groove structure 121, thereby reducing the friction between them and reducing the possibility that the abutment 130 will rotate with the movable part 120.

[0050] In some embodiments, see Figures 3 to 6 As shown, a recessed groove 134 is formed on the outer wall surface of the abutment 130, and the groove 134 is located in the groove structure 121. A protrusion 122 extends from the inner wall of the groove structure 121 toward its central axis. It is understood that since a portion of the abutment 130 is disposed within the groove structure 121, the inner wall of the groove structure 121 faces the abutment 130. Therefore, the protrusion 122 is also formed by the groove structure 121 extending toward the abutment 130. Specifically, the position of the protrusion 122 is adapted to the groove 134, and the protrusion 122 is used to connect to the groove 134. When the movable member 120 rotates relative to the supporting member 130, since the recess 134 is circumferentially located on the outer wall of the supporting member 130, the protrusion 122 will rotate within the path of the recess 134, that is, rotate around the outer wall surface of the supporting member 130. Under the action of gravity, the lower part of the supporting member 130 will still contact the inner wall of the groove structure 121, generating friction. By providing the protrusion 122 and the recess 134, the contact area between the supporting member 130 and the groove structure 121 can be reduced, thereby further reducing the friction between the supporting member 130 and the groove structure 121. Furthermore, by providing the protrusion 122 in the recess 134, the supporting member 130 can be prevented from moving relative to the groove structure 121 in the first direction to separate from the movable member 120, thus improving the connection strength between the movable member 120 and the supporting member 130.

[0051] Furthermore, in some embodiments, see [reference] Figure 4 and Figure 5As shown, the supporting member 130 has a first side 131 and a second side 132, i.e., a left side and a right side, along a first direction. A recessed groove 134 is disposed between the first side 131 and the second side 132, wherein the outer wall surface of the first side 131 and the recessed groove 134 are transitioned by an inclined plane 135. Specifically, the recessed groove 134 is a recessed structure, and the upper wall surface of the recessed groove 134 in the vertical direction is connected to the first side 131 of the supporting member 130 by an inclined plane 135. It can be understood that the recessed groove 134 is close to the first side 131, the distance between the recessed groove 134 and the first side 131 is less than the distance between the recessed groove 134 and the second side 132, and the outer wall surface of the recessed groove 134 is connected to the first side 131 by an inclined plane 135. Compared with other transition methods, such as right-angle transitions, the use of an inclined plane 135 transition can reduce stress concentration at the connection between the first side 131 and the recessed groove 134, thereby improving the strength and service life of the supporting member 130. Furthermore, the use of a beveled surface 135 as a transition reduces the interaction force between the support member 130 and the protrusion 122 when the support member 130 is installed into the groove structure 121, thereby improving assembly efficiency. In addition, the use of a beveled surface 135 as a transition can also improve the appearance quality of the support member 130 and avoid burrs, defects, and other undesirable conditions at the connection between the first side 131 and the groove 134.

[0052] In some embodiments, see Figures 1 to 4 As shown, the blocking device 100 also includes a first anti-slip pad 150, which is connected to the side of the abutment portion 111 facing away from the movable member 120. When the distance H between the abutment portion 111 and the movable member 120 increases to the point where it can abut against the door body, the first anti-slip pad 150 will come into contact with the door body. The first anti-slip pad 150 is used to increase the friction between the door body and the blocking device 100, making it less likely for the blocking device 100 to slide relative to the door body under the action of external force, thereby enhancing the blocking effect of the blocking device 100. In this embodiment, the material of the first anti-slip pad 150 is rubber or silicone or other adhesive materials. In other embodiments, the first anti-slip pad 150 can also be made of plastic, glass, or anti-slip materials such as ceramic particles.

[0053] In some embodiments, see Figures 1 to 4As shown, the actuation device 100 also includes a second anti-slip pad 160, which is connected to the side of the abutment 130 opposite to the movable member 120. When the abutment 130 moves with the movable member 120 to abut against the handle 300, the second anti-slip pad 160 will contact the handle 300. The second anti-slip pad 160 is used to increase the friction between the handle 300 and the actuation device 100, making it less likely for the actuation device 100 to slide relative to the handle 300 under the action of external force, further enhancing the actuation effect of the actuation device 100. In this embodiment, the material of the second anti-slip pad 160 is rubber or silicone. In other embodiments, the second anti-slip pad 160 can also be made of plastic, glass, or ceramic particles and other anti-slip materials.

[0054] Furthermore, the second anti-slip pad 160 is provided with a through hole 161, which connects to both sides of the second anti-slip pad 160, namely the left and right sides, along the first direction. Since the supporting member 130 extends to form a limiting portion 133 on the side opposite to the movable member 120, when the second anti-slip pad 160 is connected to the side of the supporting member 130 opposite to the movable member 120, the limiting portion 133 will pass through the through hole 161. The through hole 161 allows the limiting portion 133 to provide some support to the second anti-slip pad 160 in the second direction, thereby improving the connection strength between the second anti-slip pad 160 and the supporting member 130.

[0055] Furthermore, in some embodiments, see [reference] Figures 2 to 6 As shown, the second anti-slip mat 160 includes a hanging strap 162, which is disposed on the side of the second anti-slip mat 160 opposite to the abutment member 130. The hanging strap 162 is detachably connected to the limiting part 133. When the hanging strap 162 is connected to the limiting part 133, the side of the second anti-slip mat 160 opposite to the abutment member 130, the hanging strap 162, and the limiting part 133 together define a fixing position 163, which is used to accommodate the handle 300 for further limiting the handle 300. When the hanging strap 162 and the limiting part 133 are detached, since the limiting part 133 is located below the handle 300, the abutment part 111 does not contact the door body, and the second anti-slip mat 160 does not contact the handle 300. Moving the blocking device 100 downwards can unlock the blocking device 100 from restricting the handle 300.

[0056] Specifically, in this embodiment, the hook strap 162 is positioned above the limiting portion 133. Since the limiting portion 133 is placed below the handle 300 to prevent the handle 300 from rotating, positioning the hook strap 162 above the limiting portion 133 prevents the handle 300 from rotating upwards to unlock the lock and open the door. When the blocking device 100 is installed between the door and the handle 300, the handle 300 is housed in the fixing position 163. The side of the second anti-slip pad 160 facing away from the abutment 130, the hook strap 162, and the limiting portion 133 circumferentially limit the handle 300, restricting it and improving the blocking effect of the blocking device 100. Furthermore, the fixing position 163 allows the blocking device 100 to be hooked onto the handle 300. When the blocking device 100 is not connected and fixed to the door and the handle 300, the fixing position 163 can serve as an auxiliary hook, facilitating the installation and fixing of the blocking device 100.

[0057] In some embodiments, see Figure 1 and Figure 2 As shown, the limiting part 133 is provided with a fixing hole 1331, which connects both sides of the limiting part 133 along the second direction, that is, in this embodiment, it connects the upper and lower sides of the limiting part 133. When the hanging strap 162 is connected to the limiting part 133, the hanging strap 162 passes through the fixing hole 1331, thereby forming a connection and fixation with the limiting part 133. Through the fixing hole 1331, the limiting part 133 and the hanging strap 162 can be prevented from separating during use, thus affecting the blocking effect of the blocking device 100.

[0058] In some embodiments, see Figure 3 and Figure 4As shown, the abutment 130 includes a fixing member 136, which is connected to the limiting portion 133 and is movable relative to the limiting portion 133. The hanging strap 162 has a plurality of connecting holes 1621 spaced apart along the second direction. The fixing member 136 is movable relative to the limiting portion 133 to pass through one of the connecting holes 1621, thereby further fixing the hanging strap 162. Specifically, in this embodiment, when the hanging strap 162 is connected to the limiting portion 133, a portion of the hanging strap 162 will be located below the limiting portion 133. The fixing member 136 is connected to the lower side of the limiting portion 133, that is, when the blocking device 100 is installed between the door body and the handle 300, one side of the limiting portion 133 in the second direction faces the handle 300, and the other side faces away from the handle 300. The fixing member 136 is connected to the side of the limiting portion 133 facing away from the handle 300. The fastener 136 passes through the connection hole 1621 of the strap 162, thereby preventing the strap 162 and the limiting part 133 from separating and improving the connection stability between the strap 162 and the limiting part 133. In other embodiments, the fastener 136 may also be provided on the side of the limiting part 133 facing the handle 300, thereby connecting and fixing the limiting part 133 and the strap 162.
