Description

Technical Field

[0001] This application relates to the technical field of manual tools, and particularly to a nut supply device. Background Art

[0002] At present, with the development and progress of technology, in most industrial fields, many components of electrical equipment need to be fixed by nuts and screws. For example, the housing of the equipment can be fixed through the cooperation between the nut and the screw. Or devices such as sensors can also be fixed on the equipment through the cooperation between the nut and the screw. In addition, during the repair process of electrical equipment, the nut can also be removed from the screw to achieve the repair of the interior of the electrical equipment. Thus, it can be seen that the cooperation between the nut and the screw increases the stability of fixation and the convenience of repair, installation, etc. However, in the prior art, usually operators manually fix the nut and the screw together, that is, both the nut and the screw have matching threads, and only the operator needs to manually align the thread of the nut with the thread of the screw, and then fix the nut on the screw by rotating. However, when there are multiple nuts and multiple screws in the electrical equipment, the operator needs to manually fix the nuts on the screws one by one, and it takes a lot of effort to fix the nuts on the screws. And in winter with low temperature, sometimes the operator needs to wear warm gloves for high-altitude operation, that is, fix the nut on the screw during high-altitude operation.

Detailed implementation manners

[0031] Next, exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. It should be understood that the present application is not limited by the exemplary embodiments described herein.

[0032] Figure 1 is a schematic structural diagram of a nut supply device provided by an exemplary embodiment of the present application. Figure 2 is an exploded view of a nut supply device provided by an exemplary embodiment of the present application. Figure 3 is an enlarged view of A provided by an exemplary embodiment of the present application. Figure 4 is a rear view of a nut supply device provided by an exemplary embodiment of the present application. As Figures 1-4 shown, the nut supply device includes a receiving device 11, a ratchet mechanism 12, a fixing device 13, and a grip rod 14. The receiving device 11 includes a first cavity 111 and a second cavity 112. The first cavity 111 and the second cavity 112 communicate with each other. A fixing plate 15 is fixed in the second cavity 112. The ratchet mechanism 12 is fixed on the fixing plate 15. The ratchet mechanism 12 includes teeth 121, a fastening member 122, a limiting plate 123, an adjusting block 124, and an adjusting mechanism 125. The teeth 121 are sleeved on the fastening member 122. The limiting plate 123 and the adjusting block 124 are arranged on the first side of the fixing plate 15. The adjusting mechanism 125 is arranged on the second side of the fixing plate 15. The adjusting mechanism 125 is connected to the adjusting block 124. The adjusting mechanism 125 controls the movement direction of the adjusting block 124. The fixing device 13 is fixed on the ratchet mechanism 12. The fixing device 13 is used to accommodate nuts. The grip rod 14 is connected to the receiving device 11.

[0033] The accommodating device 11 includes a first cavity 111 and a second cavity 112. The first cavity 111 and the second cavity 112 are in communication. The second cavity 112 is mainly provided for placing a ratchet mechanism 12, a fixing device 13, etc., so as to fasten a nut to a screw through the ratchet mechanism 12 and the fixing device 13. The first cavity 111 can place the nut, or the nut slides along the first cavity 111 towards the fixing device 13. The fixing device 13 can restrict the movement of the nut and align the center of the nut with the center of the screw to achieve rotational fixation.

[0034] In the embodiment of the present application, the ratchet mechanism 12 includes teeth 121, a fastening member 122, a limiting plate 123, an adjusting block 124, and an adjusting mechanism 125. When the nut rotates, it drives the fastening member 122 to rotate. The fastening member 122 drives the teeth 121 to rotate. The fastening member 122 is connected to the fixing plate 12, and the fastening member 122 can rotate on the fixing plate 12. The rotation method can be that the fastening member 122 includes a fastening groove, and the fixing plate 12 includes a fastening protrusion, and the fastening groove and the fastening protrusion match to achieve the matching of the fastening member 122 and the fixing plate 12. The grip rod 14 is inserted into the accommodating device 11.

[0035] Preferably, there are two limiting plates 123, which are oppositely arranged on the fixing plate 15. The adjusting block 124 is preferably an isosceles triangle. The adjusting block 124 is connected to the adjusting mechanism 125, and the adjusting mechanism 125 can be an adjusting wrench. Under normal circumstances, the first angle of the adjusting block 124 (this first angle is the included angle formed by two sides of equal length, and the two equal sides can be called the two waists of the adjusting block 124), the side opposite to this angle, and the center of the gear teeth 121 are on the same straight line. The movement of the adjusting mechanism 125 drives the rotation direction of the adjusting block 124, thereby adjusting the rotation direction of the gear teeth 121. When the two waists of the adjusting block 124 coincide with the limiting plates 123 respectively, the gear teeth 121 can be locked. When the second angle and the third angle of the adjusting block 124 coincide with the limiting plates 123 respectively, the gear teeth 121 can rotate freely. When the first angle of the adjusting block 124 coincides with one of the limiting plates 123, left and right limits can be performed, that is, the limits of two relative positions of the gear teeth 121. The two limiting plates 123 are oppositely arranged on the fixing plate 15, and the two limiting plates 123 are on the same straight line. When the first angle of the adjusting block 124 coincides with the limiting plate 123 placed in the first position, the first-direction limit of the gear teeth 121 can be performed. When the first angle of the adjusting block 124 coincides with the limiting plate 123 placed in the second position, the second-direction limit of the gear teeth 121 can be performed. It can be understood that the operator can first adjust the direction of the adjusting mechanism 125 so that the two waists of the adjusting block 124 coincide with the limiting plates 123 respectively to lock the gear teeth 121. Then, the center of the nut fixed on the fixing device 13 is matched with the screw rod. In addition, the fixing device 13, the gear teeth 121, the fastening member 122, and the fixing plate 12 are all provided with through holes, and the through holes of the fixing device 13, the gear teeth 121, the fastening member 122, and the fixing plate 12 are on the same axis, so that it is convenient for the screw rod to penetrate into the through hole when the nut is rotated. When the nut is fastened on the screw rod, the operator adjusts the direction of the adjusting mechanism 125 again so that the second angle and the third angle of the adjusting block 124 coincide with the limiting plates 123 respectively, and the gear teeth 121 can rotate freely. At this time, the nut supply device can be detached from the screw rod, and finally the nut is fastened on the screw rod.

[0036] In the embodiment of the present application, the first cavity 111 is integrally in a cuboid shape, and the second cavity 112 is integrally in a circular shape. An adjusting spring is arranged between the limiting plate 123 and the shell of the second cavity 112, and the movement of the limiting plate 123 can adjust the length of the adjusting spring.

[0037] In the embodiment of the present application, the fixing device 13 is in a semi-circular ring shape, and the inner wall of the fixing device 13 matches the edges and corners of the nut, so that the nut can be fixed more firmly, and the fixing device 13 can also limit the movement of the nut.

[0038] A nut supply device provided by the present application includes a receiving device, a ratchet mechanism, a fixing device, and a grip rod. The receiving device includes a first cavity and a second cavity. The first cavity and the second cavity are in communication. A fixing plate is fixed in the second cavity. The ratchet mechanism is fixed on the fixing plate. The ratchet mechanism includes teeth, a fastening component, a limiting plate, an adjusting block, and an adjusting mechanism. The teeth are sleeved on the fastening component. The limiting plate and the adjusting block are arranged on the first side of the fixing plate. The adjusting mechanism is arranged on the second side of the fixing plate. The adjusting mechanism is connected to the adjusting block and adjusts the moving direction of the adjusting block. The fixing device is fixed on the ratchet mechanism and is used to accommodate nuts. The grip rod is connected to the receiving device. By controlling the moving direction of the adjusting block through the adjusting mechanism, the state of the teeth is adjusted, so as to effectively fix the nuts. The fixing of the teeth can ensure that the fixing device cannot move, thereby improving the fixing of the nuts. The operator only needs to align the center of the nut fixed in the fixing device with the screw rod, and then through the acting force of holding the grip rod, the nut is rotated and fixed on the screw rod. Even in the cold high-altitude operation, the operator can more conveniently fasten the nut on the screw rod through the nut supply device, improving the convenience of use.

[0039] In one embodiment, the fastening component includes a limiting ring and a fixing disk. The limiting ring is fixed on the fixing disk. The teeth are sleeved on the limiting ring. The fixing device is fixed on the fixing disk.

[0040] The fastening component includes a limiting ring and a fixing disk. The limiting ring is hollow, and the fixing disk is also hollow. Both the limiting ring and the fixing disk have through holes. When the nut is rotated, the screw rod can pass through the through holes of the fixing disk, the teeth, and the limiting ring, thereby ensuring the stability of the screw rod. The fixing device is fixed on the fixing disk to prevent the fixing device from moving freely due to external forces. It should be understood that in the embodiments of the present application, the material of the limiting ring can be selected according to the requirements of the actual application scenario, as long as the selected material of the limiting ring can drive the teeth to move. The specific material of the limiting ring is not limited in the embodiments of the present application.

[0041] It should be understood that in the embodiments of the present application, the material of the fixing disk can be selected according to the requirements of the actual application scenario, as long as the selected material of the fixing disk can fix the limiting ring. The specific material of the fixing disk is not limited in the embodiments of the present application.

A torque scale is arranged on the first rotating rod 141. The second rotating rod 142 can rotate around the first rotating rod 141. The first spring 143 is arranged inside the second rotating rod 142.

[0043] Both the first rotating rod 141 and the second rotating rod 142 have cavities inside. The first spring 143 is arranged inside the second rotating rod 142. The first rotating rod 141 is screwed into the second rotating rod 142, and one end of the first rotating rod 141 is in contact with the first spring 143. A torque scale is provided on the first rotating rod 141, and the operator selects the torque by rotating the second rotating rod 142. During the process of tightening the nut, the hand-held force is increased by the selected torque to ensure that the nut can be installed quickly.

[0044] To connect the grip rod 14 and the accommodating device 11, a sleeve 144 is provided. The thread of the sleeve 144 matches the thread of the first rotating rod 141, so that the sleeve 144 is fixedly connected to the first rotating rod 141. Figure 1 As shown, a plug board is connected to one end of the first cavity 111. The plug board can be inserted into the sleeve 144 to fix the accommodating device 11 on the sleeve 144.

[0045] In the embodiment of the present application, the outer parts of the first rotating rod 141 and the second rotating rod 142 are provided with thread shapes, so as to increase the hand-held friction during the torque adjustment process.

[0046] Figure 6 is the top view of the first cavity provided by an exemplary embodiment of the present application.

[0047] Since the nut can be conveniently placed, a first pulling block 1111 and a second pulling block 1112 are arranged on both sides of the outer wall of the first cavity 111. When the first pulling block 1111 and the second pulling block 1112 are pulled simultaneously or the first pulling block 1111 or the second pulling block 1112 is pulled, there is a certain space in the first cavity 111. The operator can place the nut in this space and then slide the nut along the first cavity 111 to the second cavity 112, so as to fix the nut through the fixing device of the second cavity 112.

[0048] In an embodiment of the present application, generally, when the second spring 1116 is not subject to an external force, its length does not change.

When an operator pulls the first pull block 1111, the first pull rod 1114 can be driven to move, and the movement of the first pull rod 1114 causes a change in the length of one end of the second spring 1116. When the operator pulls the second pull block 1112, the second pull rod 1115 can be driven to move, and the movement of the second pull rod 1114 drives the other end of the second spring 1116 to move.

In addition, the end face of the second base 162 includes a jack, which matches the first round hole, so that the first cylinder 1611 is inserted into the first round hole to limit the first base 161 (when the fourth spring 163 is in a natural state, its length is less than the length of the first cylinder 1611, so that one end of the first cylinder 1611 is always located in the jack). A fixing member 15 is disposed at one end of the first cavity 111. The fixing member 15 is inserted into one end of the first cavity 111. One end of the fixing member 15 is in a closed state. The fixing member 15 can be placed on the insertion plate to prevent the third pushing device 16 and the nut from slipping out.

[0059] It should be understood that in the embodiments of the present application, the material of the button 166 can be selected according to the requirements of the actual application scenario, as long as the selected material of the button 166 can achieve sliding on the guide rail and being fixed on the guide rail. The embodiments of the present application do not limit the specific material of the button 166.

[0060] It should be understood that in the embodiments of the present application, the shape of the button 166 can be selected according to the requirements of the actual application scenario, as long as the selected shape of the button 166 can achieve sliding on the guide rail and being fixed on the guide rail. The embodiments of the present application do not limit the specific shape of the button 166.

[0061] Figure 10The figure is a schematic structural diagram of a rotating mechanism provided by an exemplary embodiment of the present application. As Figure 10 shown, a rotating mechanism 167 is provided in the first cavity 111. The rotating mechanism 167 includes a first rotating disk 1671 and a second rotating disk 1672. Slot holes are formed on both sides of the outer wall of the first cavity 111, and a third groove is provided on the outer wall of the first cavity 111. The second rotating disk 1672 is placed in the third groove, the first rotating disk 1671 is disposed on the second rotating disk 1672, a limiting semi-ring 1673 is arranged on the first rotating disk 1671, and both ends of the limiting semi-ring 1673 penetrate through the slot holes. The first rotating disk 1671 is used for placing nuts, the limiting semi-ring 1673 is used to limit the movement of the nuts, and the limiting semi-ring 1673 can drive the first rotating disk 1671 and the second rotating disk 1672 to move.

[0062] A third groove is provided on the outer wall of the first cavity 111, and the third groove accommodates the second rotating disk 1672. The second rotating disk 1672 can move within the third groove. The first rotating disk 1671 is placed on the second rotating disk 1672, and both ends of the first rotating disk 1671 penetrate through the slot holes formed on both sides of the outer wall of the first cavity, thereby facilitating the rotation of the first rotating disk 1671 by an operator. When the operator toggles the limiting semi-ring 1673, the first rotating disk 1671 can be driven to move, and further the second rotating disk 1672 can be driven to move within the third groove.

[0063] In the embodiment of the present application, the width of the slot hole is only a part of the width of the inner wall of the first cavity 111. To facilitate the operator to toggle the limiting semi-ring 1673, concave and convex patterns are provided on the outer wall of the limiting semi-ring 1673 passing through the slot hole to increase the contact area with the operator's finger. The outer wall of the limiting semi-ring 1673 passing through the slot hole occupies two-thirds of the length of the slot hole opened in the first cavity, which is beneficial for the limiting semi-ring 1673 to pass through the slot hole and facilitates rotation. In addition, the nut arranged on the limiting semi-ring 1673 is in close contact with the guide rail of the first cavity. By setting the outer wall of the limiting semi-ring 1673 passing through the slot hole to occupy two-thirds of the length of the slot hole opened in the first cavity, the nut can also be limited.

[0064] In the embodiment of the present application, the limiting semi-ring 1673 is in the shape of a semicircular ring, that is, two-thirds of a circular ring, and the inner wall of the limiting semi-ring 1673 is the circumscribed circle of the nut. The operator places the nut in the fixing device, and then rotates the first rotating disk 1671, and the first rotating disk 1671 drives the limiting semi-ring 1673 to rotate, so that the opening of the limiting semi-ring 1673 is aligned with the fixing device, and the nut slides from the fixing device to the opening of the limiting semi-ring 1673, and then the operator rotates the limiting semi-ring 1673 again by a certain angle, so that the limiting semi-ring 1673 rotates and the opening of the limiting semi-ring 1673 faces the third pushing device, so that the nut slides along the guide rail toward the third pushing device. The two ends of the limiting semi-ring 1673 are acute angles, so that when the nut is rotated, the next adjacent nut moves toward the third pushing device, thereby leaving a rotation gap for the limiting semi-ring 1673 and reducing the resistance during rotation. It can be understood that when the first base 161 is subjected to nut pressure (when the limiting half ring 1673 rotates, it will press the remaining nut to move toward the third pushing device, thereby pressing the first base 161 to move toward the interior of the first cavity, so that the fourth spring 163 is in a compressed state), the first cylinder on the first base 161 is inserted into the socket.

[0065] In an embodiment of the present application, when the nut is slid along the guide rail to the opening of the limiting half ring, the operator matches the center of the nut with the screw rod. When the nut is hung on the screw rod, the operator moves the limiting half ring again to make the opening of the limiting half ring face the second cavity. At this time, the operator holds the nut supply device, and the nut slides into the fixing device along the direction of the first cavity sliding toward the fixing device.

[0066] It is understandable that the first cavity 111 can not only realize the sliding of the nut, but also realize the storage of the nut, that is, the nuts are slid one by one to the cavity between the third pushing device and the first rotating disk 1671 according to the above method. The number of nuts stored in the first cavity 111 changes according to the actual length of the first cavity 111.

[0067] It should be understood that the embodiment of the present application can select the length of the first cavity 111 according to the needs of the actual application scenario. The selected length of the first cavity 111 only needs to be able to store the nut. The embodiment of the present application does not limit the specific length of the first cavity 111.

[0068] In an embodiment of the present application, when an operator uses a nut stored in the first cavity 111, the operator slides the nut to the opening of the limiting half ring 1673, and the operator rotates the first rotating disk 1671, thereby driving the limiting half ring 1673 to rotate. The movement of the limiting half ring 1673 can drive the nut to rotate, and make the opening of the limiting half ring 1673 face the second cavity, and the nut slides toward the fixing device of the second cavity, thereby achieving the installation of the nut.

[0069] Specific principle of this application:

[0070] When nuts need to be stored, the operator can place the nuts in the fixing device. At this time, rotate the limiting half-ring, and the movement of the limiting half-ring drives the first rotating disk and the second rotating disk to rotate. Among them, the second rotating disk rotates in the third groove. When the limiting half-ring rotates a certain angle, align the opening of the limiting half-ring with the fixing device or the second cavity. Then the nut slides from the fixing device to the opening of the limiting half-ring. When the operator rotates the limiting half-ring a certain angle again, the limiting half-ring drives the nut to rotate, and the nut slides along the guide rail towards the third pushing device, thereby realizing the storage of nuts.

[0071] When the operator uses the nuts stored in the first cavity, the operator presses the button, and the pressing piece moves a certain distance (below the guide rail) towards the inside of the first cavity under the pressure of the button. The button moves towards the second cavity with the operator's pushing force, thereby sliding the nut to the opening of the limiting half-ring. At this time, the operator can cancel the pressure on the button, and the pressing piece drives the button to move up a certain distance, so that the button fits with the serrations of the guide rail, so that the button can be fixed on the guide rail, and can also limit the nut from sliding along the guide rail again, and will also press the remaining nuts in the first cavity towards the third pushing device.

[0072] When sliding the nut along the guide rail to the opening of the limiting half-ring, the operator matches the center of the nut with the screw. When the nut is hung on the screw, the operator moves the limiting half-ring again so that the opening of the limiting half-ring faces the second cavity. At this time, the operator holds the nut supply device, and the nut slides along the first cavity towards the fixing device and into the fixing device.

[0073] When installing the nut, the operator can set the torque value to meet the torque of the nut, that is, determine the required torque value by rotating the second rotating rod. The operator controls the adjusting block so that the two waists of the adjusting block coincide with the limiting plates respectively to lock the gear teeth. The operator matches the round hole of the nut with the screw, and then applies a certain force to the grip rod and continuously rotates the nut supply device, thereby tightening the nut fixed in the fixing device (the nut is already hung on the screw) on the screw. Control the moving direction of the adjusting block through the adjusting mechanism to adjust the state of the gear teeth, so as to effectively fix the nut. The fixing of the gear teeth can ensure that the fixing device cannot move, thereby improving the fixing of the nut. The operator only needs to align the center of the nut fixed in the fixing device with the screw, and then apply a force by holding the grip rod to rotate the nut and fix it on the screw.

[0074] When the nut installation is completed, the operator rotates the adjusting mechanism again so that the second angle and the third angle of the adjusting block coincide with the limiting plates respectively so that the gear teeth can rotate freely, so that the nut supply device can be disengaged from the screw.
