Description
Technical Field
[0001] The utility model relates to the field of medical equipment, in particular to a locking mechanism, a storage rack comprising the same, and a mobile X-ray machine. Background Art
[0002] Mobile digital radiography (DR) is frequently used in patient rooms, providing convenient X-ray examinations for patients with limited mobility. X-ray receivers play a central role in mobile DR, capturing high-quality X-ray images that provide crucial support for doctors' diagnoses.
[0003] Due to the high value and core status of X-ray receiving devices, their security is of paramount importance. Once stolen, it will not only cause huge economic losses to the hospital, but also affect the normal operation of medical services.
[0004] Typically, mobile DRs are parked in the hallways outside wards, increasing the risk of theft. Hallways are often heavily trafficked and lack effective oversight, making them easy targets for theft. Utility Model Content
[0005] The purpose of the utility model is to provide a locking mechanism, which can be used to lock an X-ray receiving device to prevent the X-ray receiving device from being stolen.
[0006] Another object of the present utility model is to provide a storage rack comprising the above-mentioned locking mechanism, which can lock the X-ray receiving device to prevent the X-ray receiving device from being stolen.
[0007] Another object of the present invention is to provide a mobile X-ray machine comprising the above-mentioned storage rack, which can lock the X-ray receiving device to prevent the X-ray receiving device from being stolen.
[0008] The utility model provides a locking mechanism, comprising a bracket, an active member, a stop member, a driven member and a locking and unlocking unit. The active member is arranged on the bracket and can move between a first position and a second position relative to the bracket along a first direction and its opposite direction. The stop member is arranged on the bracket and can move between a stop position and a retracted position relative to the bracket along a second direction and its opposite direction. The second direction is perpendicular to the first direction. The driven member is connected between the active member and the stop member along a third direction and is rotatably arranged on the bracket around a first axis parallel to the third direction. The third direction is perpendicular to the first direction and the second direction. During the process of the active member moving from the second position to the first position along the first direction, the active member drives the driven member to rotate around the first axis along the first clockwise direction, and then drives the stop member to move from the retracted position to the stop position along the second direction. The locking and unlocking unit is arranged on the bracket and can limit the active member in the first position. The locking and unlocking unit can also release the active member to allow the active member to move to the second position.
[0009] By arranging an active part, a stop part, a driven part and a locking and unlocking unit on the bracket, and through the mutual cooperation between the above four parts, the locking mechanism can drive the driven part to move when force is applied to the active part, and then drive the stop part to move to the stop position to exert a locking effect.
[0010] In another schematic embodiment of the locking mechanism, the follower includes an active arm and a passive arm. The active arm and the passive arm are parallel to a third direction. The active member is provided with a first long hole extending along the second direction. The stop member is provided with a second long hole extending along the first direction. The active arm is inserted into the first long hole, and the passive arm is inserted into the second long hole. During the movement of the active member from the second position to the first position along the first direction, the active arm drives the follower to rotate along the first axis in a first clockwise direction, so that the passive arm drives the stop member to move from the retreat position to the stop position along the second direction. The above structure is simple and compact, has high space utilization efficiency, and reliable motion transmission.
[0011] In another exemplary embodiment of the locking mechanism, the lever arm of the active member acting on the active arm is smaller than the lever arm of the stop member acting on the driven arm. In the above structure, the movement stroke of the active member is smaller than the movement stroke of the stop member.
[0012] In another schematic embodiment of the locking mechanism, the locking and unlocking unit includes a locking and unlocking member. The locking and unlocking member is rotatably arranged on the bracket around a second axis parallel to the third direction. The locking and unlocking member includes a locking end protruding in the opposite direction of the second direction. The active member is provided with a groove with an opening facing the second direction. The locking and unlocking member rotates around the second axis along a first clockwise direction and the opposite direction between an unlocking position and a locking position. In the locked position, the locking end can be inserted into the groove to limit the active member to the first position. In the unlocked position, the locking end exits the groove and releases the active member to allow the active member to move to the second position. The above structure is simple and efficient, and the locking effect is reliable.
[0013] In another schematic embodiment of the locking mechanism, the bracket includes an abutting end. The abutting end abuts against the lock-unlocking member located in the locked position to prevent the lock-unlocking member from continuing to rotate in the first clockwise direction. The lock-unlocking unit also includes a first spring. The first spring acts on the lock-unlocking member and the bracket to drive the lock-unlocking member to rotate in the opposite direction of the first clockwise direction. The locking end has a first guide surface that is gradually inclined toward the first direction. The front end of the active member along the first direction has a second guide surface that is gradually inclined toward the first direction. During the movement of the active member to the first position, the lock-unlocking member rotates around the second axis under the guidance of the first guide surface and the second guide surface, first leaving the locked position, and then rotates back to the locked position under the elastic restoring force of the first spring, so that the locking end is inserted into the groove. The above structure is simple, easy to maintain and has a reliable locking function, and the locking process is smoothly transitioned under the guidance of the first guide surface and the second guide surface.
[0014] In another exemplary embodiment of the locking mechanism, the locking / unlocking member further includes an extension extending parallel to the third direction to receive a thrust perpendicular to the third direction and thereby drive the locking / unlocking member to rotate. This facilitates unlocking the locking mechanism during power outage maintenance by applying force to the extension.
[0015] In another schematic embodiment of the locking mechanism, the locking and unlocking unit further includes an electromagnetic telescopic member, which includes an electromagnet, a pulling member and a second spring. The electromagnet is fixedly mounted on the bracket. One end of the pulling member is overlapped to the locking and unlocking member, and the other end is arranged on the electromagnet. When the electromagnet is energized, the pulling member can move in a first direction, pulling the locking and unlocking member located in the locked position to rotate around the second axis in a first clockwise direction to the unlocked position. The second spring is sleeved on the pulling member, and its two ends respectively abut against the electromagnet and the pulling member. When the electromagnet is de-energized, the second spring drives the pulling member to move in the opposite direction of the first direction through elastic restoring force. The above structure can quickly respond to unlocking requirements, accurately control the unlocking position, accurately reset automatically, and is easy to integrate and maintain.
[0016] In another exemplary embodiment of the locking mechanism, a third spring is further included. The third spring is sleeved around the active member, with its ends respectively abutting the bracket and the active member. After the locking and unlocking unit releases the active member, the third spring, through its elastic restoring force, drives the active member from the first position to the second position. This structure is simple, enables automatic reset of the active member, and is easy to integrate and maintain.
[0017] In another exemplary embodiment of the locking mechanism, a tension spring is further included. One end of the tension spring is connected to the follower and positioned between the follower arm and the first axis. The other end of the tension spring is connected to the bracket and positioned forward of the first axis along the first direction. This structure is simple and easy to maintain, and serves to stabilize the locking mechanism.
[0018] The storage rack provided by the utility model includes a frame body and the above-mentioned locking mechanism. The frame body has a slot for storing items, and the slot is open on one side opposite to the first direction to form an opening, and the opening is used to insert or remove items from the slot. The locking mechanism is arranged on the frame body, and the active member and the stop member extend out of the frame body. By applying force to the active member, it moves from the second position to the first position along the first direction, thereby driving the stop member to move to the stop position to insert into the opening, thereby preventing the items in the slot from being removed. The storage rack including the above-mentioned locking mechanism can lock the X-ray receiving device to prevent the X-ray receiving device from being stolen.
[0019] The present invention provides a mobile X-ray machine comprising an X-ray generator, an X-ray receiving device, and a storage rack. The X-ray generator is configured to generate X-rays. The X-ray receiving device is configured to receive the X-rays and generate X-ray images. The storage rack is configured to accommodate the X-ray receiving device. The mobile X-ray machine including the storage rack is capable of locking the X-ray receiving device to prevent theft. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings. The same reference numerals in the figures represent components with the same structure or similar structures but the same functions.
[0067] In this document, “illustrative” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “illustrative” should not be interpreted as a more preferred or more advantageous technical solution.
[0068] In this article, "first", "second" and "third" do not indicate their importance or order, but are only used to indicate the difference between them for the convenience of document description.
[0069] To simplify the drawings, each figure schematically shows only the parts related to the present invention, which do not represent the actual structure of the product.
[0070] Figure 1 FIG1 is a schematic structural diagram of a schematic embodiment of a locking mechanism. Figure 1 In the exemplary embodiment, the locking mechanism 100 includes a bracket 10 , an active member 20 , a stopper 30 , a driven member 40 and a locking and unlocking unit 50 .
[0071] The active member 20 is disposed on the bracket 10 and can move relative to the bracket 10 between a first position and a second position along a first direction D1 and its reverse direction. Figure 1The first position is located in front of the second position along the first direction D1. Figure 1 In the exemplary embodiment, the first position is located below the second position. In the exemplary embodiment, the active member 20 includes a button 24. An operator applies force on the button 24 to move the active member 20 downward from the second position to the first position. In other exemplary embodiments, the button 24 may be of other forms depending on the application scenario.
[0072] The stopper 30 is provided on the bracket 10 and can move relative to the bracket 10 between a stop position and a retracted position along a second direction D2 and its reverse direction. Figure 1 As shown by the left and right double arrows parallel to the second direction D2. The second direction D2 is perpendicular to the first direction D1. The stop position is located in front of the retracted position along the second direction D2. Figure 1 In the exemplary embodiment, the stopper 30 is located to the left of the retracted position. In the exemplary embodiment, the stopper 30 includes a locking tongue 32 extending along the second direction D2. When the stopper 30 is in the stopper position, the locking tongue 32 extends out of the locking mechanism 100 along the second direction D2 to lock the lock. When the stopper 30 is in the retracted position, the locking tongue 32 retracts in the direction opposite to the second direction D2 to unlock the lock. In other exemplary embodiments, the locking tongue 32 may also have other configurations depending on the application scenario.
[0073] The follower member 40 is connected between the driving member 20 and the stop member 30 along a third direction D3 and is rotatably mounted on the bracket 10 about a first axis X1 parallel to the third direction D3. The third direction D3 is perpendicular to the first direction D1 and the second direction D2. As the driving member 20 moves from the second position to the first position along the first direction D1, the driving member 20 drives the follower 40 to rotate about the first axis X1 in a first clockwise direction S1, thereby driving the stop member 30 to move from the retracted position to the stop position along the second direction D2.
[0074] The locking and unlocking unit 50 is disposed on the bracket 10 and can restrict the active member 20 to the first position. The locking and unlocking unit 50 can also release the active member 20 to allow the active member 20 to move to the second position.
[0075] Figure 1 The state shown is the locked state of the locking mechanism 100. At this time, the active member 20 has left the second position and moved downward to the first position. The locking and unlocking unit 50 restricts the active member 20 to the first position. Driven by the active member 20, the follower 40 rotates around the first axis X1 along the first clockwise direction S1, pushing the stop member 30 from the retracted position along the second direction D2 to the stop position.
[0076] exist Figure 1In the state shown, the locking and unlocking unit 50 can also release the active member 20 to allow the active member 20 to move upward to the second position. Driven by the active member 20, the follower member 40 rotates around the first axis X1 in the opposite direction of the first hour hand, pushing the stop member 30 from the stop position in the opposite direction of the second direction D2 to the retracted position, so that the locking mechanism 100 is in an unlocked state.
[0077] By arranging an active part, a stop part, a driven part and a locking and unlocking unit on the bracket, and through the mutual cooperation between the above four parts, the locking mechanism can drive the driven part to move when force is applied to the active part, and then drive the stop part to move to the stop position to exert a locking effect.
[0078] Figure 2 is an exploded view illustrating the locking mechanism. Figure 2 In the exemplary embodiment, the driven member 40 includes a driving arm 41 and a driven arm 42. The central axes of the driving arm 41 and the driven arm 42 are parallel to the third direction D3. The driving member 20 is provided with a first long hole 21 extending along the second direction D2. The stopper 30 is provided with a second long hole 31 extending along the first direction D1. The driving arm 41 is inserted into the first long hole 21, and the driven arm 42 is inserted into the second long hole 31. When the driving member 20 moves from the second position to the first position along the first direction D1, that is, Figure 2 During the downward movement, the active arm 41 receives a downward thrust from the active member 20, thereby driving the driven member 40 to rotate about the first axis X1 in the first clockwise direction S1. Subsequently, the driven arm 42 drives the stop member 30 to move from the retracted position to the stop position in the second direction D2. The above structure is simple and compact, with high space utilization efficiency and reliable motion transmission.
[0079] In order to clearly show the motion relationship between the follower 40 and the stopper 30, Figure 3A and Figure 3B Schematic diagram for explaining the interaction between the follower and the stopper. Figure 3A and Figure 3B The active member 20 and the bracket 10 are not shown. Figure 3A and Figure 3B As shown, in the exemplary embodiment, the lever arm of the active member 20 acting on the active arm 41 is the distance from the first axis X1 to the active arm 41, while the lever arm of the stop member 30 acting on the driven arm 42 is the distance from the first axis X1 to the driven arm 42. The lever arm of the active member 20 acting on the active arm 41 is smaller than the lever arm of the stop member 30 acting on the driven arm 42. Therefore, the active member 20 can push the stop member 30 to move a greater distance with a smaller movement stroke. That is, when the button 24 undergoes a smaller displacement, the lock tongue 32 can produce a larger displacement. This allows the stop member to effectively perform its locking function while maintaining a compact structure.
[0080] like Figure 3A As shown in , the locking mechanism is in the locked state. Figure 3B As shown, the locking mechanism is in the unlocked state. Figure 3B Active element 20( Figure 3B The active member 20 is not shown in the figure, but the position of the active member 20 can be explained from the position of the active arm 41) from the second position along the first direction D1 (ie Figure 3B The active arm 41 moves to the first position, the position of the active arm 41 decreases, and the follower 40 then rotates around the first axis X1 along the first clockwise direction S1, and the follower arm 42 pushes the stopper 30 to rotate along the second direction D2 (i.e. Figure 3B The locking mechanism 100 extends out of the locking tongue 32 along the second direction D2 to play a locking role, that is, to achieve the locking effect. Figure 3A locked state.
[0081] Figure 3A Active part 20( Figure 3A Not shown, but the position of the active member 20 can be described from the position of the active arm 41) is released by the locking unlocking unit 50 in the opposite direction of the first direction D1 (ie Figure 3A The active arm 41 moves upward, the position of the driven member 40 is raised, and the driven member 40 rotates around the first axis X1 in the opposite direction of the first clockwise direction S1, and the driven arm 42 pushes the stopper 30 in the opposite direction of the second direction D2 (i.e. Figure 3A The lock tongue 32 moves from the stop position to the retracted position to unlock the lock, that is, to the right direction. Figure 3B unlocked state.
[0082] Figure 4A and Figure 4B Schematic diagram for explaining the interaction between the locking and unlocking unit and the active member. Figure 4A and Figure 4B , the locking and unlocking unit 50 includes a locking and unlocking member 51. The locking and unlocking member 51 is rotatably arranged on the bracket 10 around a second axis X2 parallel to the third direction D3. The locking and unlocking member 51 includes a locking end 511 protruding in the opposite direction of the second direction D2. The active member 20 is provided with a groove 22 with an opening facing the second direction D2. The locking and unlocking member 51 rotates around the second axis X2 along a first clockwise direction S1 and the opposite direction between an unlocking position and a locking position. In the locked position, the locking end 511 can be inserted into the groove 22 to limit the active member 20 to the first position. In the unlocked position, the locking end 511 exits the groove 22 and releases the active member 20 to allow the active member 20 to move to the second position. The above structure is simple and efficient, and the locking effect is reliable.
[0083] In the exemplary embodiment, the bracket 10 includes an abutment end 11. The abutment end 11 abuts the lock / unlock member 51 in the locked position to prevent further rotation of the lock / unlock member 51 in the first clockwise direction S1. The lock / unlock unit 50 also includes a first spring 52. The first spring 52 acts on the lock / unlock member 51 and the bracket 10 to drive the lock / unlock member 51 to rotate in the direction opposite to the first clockwise direction S1. The locking end 511 has a first guide surface 53 that is gradually inclined toward the first direction D1. The active member 20 has a second guide surface 23 at its front end along the first direction D1 that is gradually inclined toward the first direction D1. During movement of the active member 20 to the first position, the lock / unlock member 51 rotates about the second axis X2 under the guidance of the first guide surface 53 and the second guide surface 23, first leaving the locked position, and then, under the elastic restoring force of the first spring 52, rotates back to the locked position, allowing the locking end 511 to insert into the groove 22. The above structure is simple, easy to maintain, and provides a reliable locking function. The locking process is smooth and transitional, guided by the first guide surface 53 and the second guide surface 23.
[0084] like Figure 4A As shown, the locking mechanism 100 is in a locked state. Figure 4B As shown, the locking mechanism 100 is in an unlocked state. Figure 4B The locking and unlocking member 51 is in the locked position due to the restriction of the abutting end 11 of the bracket 10, and the active member 20 moves along the first direction D1 ( Figure 4B The active member 20 moves in the downward direction (in the middle) and gradually abuts against the locking and unlocking member 51. Under the guidance of the first guide surface 53 and the second guide surface 23, the active member 20 pushes the locking and unlocking member 51 in the second direction D2, causing it to rotate around the second axis X2 in the first clockwise direction S1 and first leave the locked position. The first spring 52 is compressed. Under the elastic restoring force of the first spring 52, the locking and unlocking member 51 rotates around the second axis X2 in the opposite direction of the first clockwise direction S1 and returns to the locked position, so that the locking end 511 is inserted into the groove 22 to lock the active member 20, thus achieving the locking position. Figure 4A locked state.
[0085] Figure 4A The locking and unlocking member 51 rotates around the second axis X2 in the first clockwise direction S1 under the action of external force, so that the locking end 511 leaves the groove 22, the active member 20 is released, the first spring 52 is compressed, and the locking and unlocking member 51 leaves the locked position, that is, the locking and unlocking member 51 is released. Figure 4B unlocked state. When the active member 20 moves in the opposite direction of the first direction D1 (i.e. Figure 4B During the movement from the locking member 51 to the second position (in the upward direction), under the elastic restoring force of the first spring 52, the locking and unlocking member 51 can rotate around the second axis X2 in the opposite direction of the first clockwise direction S1, and stay in the locked position under the restriction of the abutting end 11 of the bracket 10, waiting to lock the active member 20 again.
[0086] In the exemplary embodiment, the locking and unlocking unit 50 further includes an electromagnetic telescopic member 54. Figure 1 The electromagnetic telescopic member 54 includes an electromagnet 541, a pulling member 542 and a second spring 543. The electromagnet 541 is fixed to the bracket 10. One end of the pulling member 542 is connected to the locking and unlocking member 51, and the other end is set on the electromagnet 541. The pulling member 542 can move in the first direction (i.e. Figure 1 The second spring 543 is sleeved on the pulling member 542, and its two ends respectively abut against the electromagnet 541 and the pulling member 542. When the electromagnet 541 is powered off, the second spring 543 drives the pulling member 542 in the opposite direction of the first direction D1 (i.e., the direction of rotation of the second spring 543). Figure 1 The locking / unlocking member 51 rotates about the second axis X2 in the direction opposite to the first clockwise direction S1 to the locked position. The above structure can quickly respond to unlocking requests, accurately control the unlocking position, accurately reset automatically, and is easy to integrate and maintain.
[0087] In an exemplary embodiment, the locking and unlocking member 51 further includes two protruding ends 513. Referring to Figure 4, the two protruding ends 513 are respectively provided at both ends of the locking and unlocking member 51 along the first direction D1 (i.e., the upper and lower ends of the locking and unlocking member 51 in Figure 4). The protruding ends 513 extend in a direction parallel to the third direction D3 to receive a thrust perpendicular to the third direction D3 and drive the locking and unlocking member 51 to rotate. Here, the thrust perpendicular to the third direction D3 is a thrust along the second direction D2 or its opposite direction. Under the action of the thrust, the locking and unlocking member 51 rotates from the insertion position to the withdrawal position along the first clockwise direction S1 around the second axis X2 to release the active member 20. For the protruding end 513 located at the upper end of the locking and unlocking member 51, applying a thrust along the second direction D2 can drive the locking and unlocking member 51 to rotate along the first clockwise direction S1 around the second axis X2 to unlock. Applying a thrust in the direction opposite to the second direction D2 to the extension 513 at the lower end of the locking / unlocking member 51 also rotates the locking / unlocking member 51 about the second axis X2 in the first clockwise direction S1 to unlock the lock. This allows the operator to manually apply force to the extension 513 to unlock the lock mechanism even when the electromagnet is powered off, such as during maintenance.
[0088] In the exemplary embodiment, the locking mechanism 100 further includes a third spring 60. Figure 1The third spring 60 is sleeved on the active member 20, and the two ends of the third spring 60 respectively abut against the bracket 10 and the active member 20. After the locking and unlocking unit 50 releases the active member 20, the third spring 60 drives the active member 20 from the first position to the second position (i.e. Figure 1 The above structure is simple, can automatically reset the active component, and is easy to integrate and maintain.
[0089] In the exemplary embodiment, the locking mechanism 100 further includes a tension spring 70 . Figure 5 for Figure 1 Detailed view of the section along VV. Figure 5 One end of the tension spring 70 is connected to the follower 40 and is located between the follower arm 42 and the first axis X1. The other end of the tension spring 70 is connected to the bolt 71 located on the bracket 10 and is located in front of the first axis X1 along the first direction D1. During the rotation of the follower 40, the tension spring 70 is always in a tensioned state. During the unlocking process of the locking mechanism 100, the third spring 60 recovers its deformation to cause the active part 20 to move in the opposite direction of the first direction D1. The speed of deformation recovery of the third spring 60 is relatively fast, which can easily cause the active part 20 to collide with the bracket 10 and generate noise. The tension spring 70 is always in a tensioned state. Under the action of its elastic restoring force, it can effectively restrain the movement of the follower 40 to offset part of the elastic force of the third spring 60, so that the active part 20 moves smoothly and the active part 20 and the stopper 30 can be stably connected. The above structure is simple and easy to maintain, and plays a role in stabilizing the locking mechanism.
[0090] Figure 6 For illustration purposes only Figure 1 Schematic diagram of the structure of the storage rack 90 of the locking mechanism shown. In the exemplary embodiment, see Figure 6 The storage rack 90 provided by the present invention is used to store the X-ray receiving device of the mobile DR, such as a flat-panel detector. However, it is not limited to this. The storage rack 90 can also be used to store other items. In a variant embodiment, the storage rack 90 can be used not only to accommodate the X-ray receiving device, but also to charge the X-ray receiving device. The storage rack 90 can be set to be independent of the mobile DR, or it can be set to be a part of the mobile DR. In an exemplary embodiment, the storage rack 90 includes a frame body 91 and two locking mechanisms 100 with opposite installation directions. In other exemplary embodiments, the number of locking mechanisms 100 can be adjusted according to actual application requirements.
