Description

Technical Field

[0001] This invention relates to the field of emergency medical equipment technology, specifically to an emergency vehicle mounting system. Background Technology

[0002] During the emergency transfer of patients by ambulances, defibrillators, ventilators, oxygen cylinders, infusion pumps, and syringe pumps are essential accompanying emergency medical equipment. Currently, a patent application (patent number 201610688656.6) entitled "Hanging System for Emergency Vehicles" discloses a hanging system. This system consists of a hanging plate, a slide seat slidably mounted on the hanging plate, a mounting bracket installed on the slide seat, and a locking mechanism for locking the slide seat to the hanging plate. The locking mechanism includes: a locking hole in the hanging plate; a pin hole in the slide seat; a pin shaft passing through the pin hole; a fixing block on the outer wall of the slide seat on one side of the pin hole; a handle fixed to the pin shaft; a movable block on the handle for sliding engagement with the fixing block; the two end faces of the movable block and the fixing block that slide together are gradually outwardly inclined slopes; and a compression spring between the handle and the mounting bracket. In the aforementioned mounting system, when the slide is moved to align the pin hole with the locking hole, the handle, under the inward force of the compression spring, will gradually rotate and move inward along the fixing block, synchronously driving the pin to rotate and move inward until it extends out of the pin hole and inserts into the locking hole, thereby fixing the slide to the hanging plate. Since the locking shaft only relies on the spring force of the compression spring to maintain its position inserted into the locking hole, it is prone to vibration due to the bumps of the ambulance during the operation of the ambulance. When the vibration amplitude of the pin is too large, it will disengage from the locking hole, making it impossible to continue locking the slide to the hanging plate. This causes the slide and the emergency equipment installed on the slide to shake on the hanging plate. In severe cases, it may cause the slide and the emergency equipment to fall off the hanging plate, resulting in damage to the emergency equipment. The stability and safety of use are poor. Summary of the Invention

[0003] The purpose of this invention is to provide an emergency vehicle mounting system with high stability and safety in use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an emergency vehicle mounting system, comprising a hanging plate installed on the wall of an emergency vehicle and hooks for mounting emergency equipment. The surface of the hanging plate is provided with a plurality of positioning holes spaced apart along its length. The hooks, via a sliding mechanism, can move along the length of the hanging plate through any of the positioning holes, and when they move to any positioning hole, they can engage with that positioning hole and lock themselves securely to the hanging plate. The hooks include: a base, a cover plate mounted on the base, and a connecting mechanism mounted on the cover plate for connecting and fixing with emergency equipment. A channel penetrating to the side wall of the cover plate is provided on the surface of the cover plate facing the base. A connecting channel is provided on the base, and when the hooks pass through the positioning holes, they can engage with the positioning holes and lock themselves securely to the hanging plate. The positioning hole corresponds to the pin hole, through which a lock cylinder is inserted. One end of the lock cylinder extends into the channel and is fitted with a handle. The handle extends out of the cover plate through the channel. A spring is provided between the handle and the cover plate, or between the lock cylinder and the cover plate. Under the action of the spring, the handle always tends to rest against the base and cause the lock cylinder to extend out of the pin hole and insert into the positioning hole of the hanging plate. A locking slot corresponding to the handle is provided on the inner wall of the channel on one side of the handle when the lock cylinder is inserted into the positioning hole of the hanging plate. When the lock cylinder is inserted into the positioning hole of the hanging plate and the handle is rotated to engage with the locking slot, the lock cylinder can maintain the locked posture of being inserted into the positioning hole of the hanging plate so that the hook is stably fixed to the hanging plate. When the handle is rotated to disengage from the locking slot and the handle is pulled outward to disengage the lock cylinder from the positioning hole of the hanging plate, the hook can move relative to the hanging plate again.

[0005] Furthermore, in the aforementioned emergency vehicle mounting system, a locking block is detachably installed on the inner wall of the channel via connecting bolts. A gap is left between the locking block and the base for the handle to be engaged, and this gap forms a locking slot in the channel for the handle to rotate and engage.

[0006] Furthermore, in the aforementioned emergency vehicle mounting system, the surface of the locking block facing the base is a first inclined surface that gradually slopes downward toward the base along the direction in which the handle is turned into the locking slot, and a second inclined surface is provided on the handle that can engage with the first inclined surface when the handle is turned into the locking slot.

[0007] Furthermore, in the aforementioned emergency vehicle hanger system, the connecting mechanism includes a hanging core with a groove on the surface of a cover plate away from the base. One end of the groove extends upward to the side wall of the cover plate to form an insertion port. A hanging plate is installed at the opening of the groove, with its upper end extending upward to the insertion port of the groove. A positioning notch extending downward to the lower part of the hanging plate is provided at the upper end of the hanging plate. The surface of the hanging core is provided with several threaded holes for connecting and fixing with emergency equipment, as well as fixing bolts that match the threaded holes. Positioning guide grooves are symmetrically provided on both sides of the hanging core. The hanging core is hung on the hanging plate by aligning the two positioning guide grooves and fitting them into the two sides of the positioning notch. A locking mechanism is provided on the cover plate. The locking mechanism can not only fix the hanging core when it is hung on the hanging plate, but also unlock the hanging core so that it can be removed from the hanging plate.

[0008] Furthermore, in the aforementioned emergency vehicle hanger system, the locking mechanism includes a locking rod hinged to a groove in a cover plate via a pin. The ends of the locking rod on both sides of the pin are a driving end and a locking end, respectively. The locking end of the locking rod is attached to the back of the hanging core on the hanger plate. The driving end of the locking rod extends out of the cover plate from the insertion port and is equipped with a driving handle. A locking spring is provided between the locking end of the locking rod and the cover plate. Under the elastic force of the locking spring, the locking end of the locking rod always tends to press the hanging core tightly against the hanger plate.

[0009] Furthermore, in the aforementioned emergency vehicle mounting system, the connecting mechanism includes: a plurality of threaded holes for connecting and fixing with emergency equipment, and fixing bolts matching the threaded holes, provided on the surface of the cover plate away from the base.

[0010] Furthermore, in the aforementioned emergency vehicle hanger system, the sliding mechanism includes: a T-shaped track arranged along its length on the surface of the hanging plate, several openings spaced apart along the edge of the T-shaped track, and several pulleys installed on the back of the hook, which can move along the hanging plate by inserting the pulleys into the T-shaped track through the openings.

[0011] Through the implementation of the above technical solutions, the beneficial effects of the present invention are: (1) After the lock cylinder of the hook is inserted into the positioning hole of the hanging plate, the handle is rotated and locked into the slot, so that the lock cylinder can always maintain the locked posture of being inserted into the positioning hole of the hanging plate. In the locked posture, the lock cylinder will not change position with the positioning hole in the axial direction due to the bumps of the emergency vehicle, ensuring that the lock cylinder can always maintain the locked posture of being inserted into the positioning hole of the hanging plate, thereby effectively preventing the emergency equipment from being damaged due to the lock cylinder coming out of the positioning hole, and improving the stability and safety of use; (2) When the lock cylinder is inserted into the positioning hole of the hanging plate under the action of the spring, the handle is rotated and locked into the slot. During the process of opening, the rotation of the handle will not cause the lock cylinder to change its axial position in the pin hole, ensuring that the lock cylinder can always maintain the locked posture of being inserted into the positioning hole of the hanging plate during the rotation of the handle, thereby improving the stability of use; (3) The structure on the hook for connecting with the emergency equipment is designed with a split connection structure. The hanging core can be pre-installed on the emergency equipment, and then the hanging core is hung on the hanging plate of the hook, so that the emergency equipment can be installed on the hook, which is convenient to install; and only by turning the drive handle to release the locking rod from the hanging core, the emergency equipment and the hanging core can be easily removed from the hook, which is very convenient to operate.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. Example 1

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 As shown, an emergency vehicle mounting system includes a hanging plate 1 installed on the wall of the emergency vehicle and hooks 2 for mounting emergency equipment. The surface of the hanging plate 1 is provided with a plurality of positioning holes 3 arranged at intervals along its length. The hooks 2 can move along the length of the hanging plate 1 through any position of the positioning hole 3 via a sliding mechanism, and can cooperate with any positioning hole 3 to lock and fix them on the hanging plate 1 when they move to any positioning hole 3. In this embodiment, the sliding mechanism includes: a T-shaped track 4 arranged along its length on the surface of the hanging plate 1, a plurality of openings 5 ​​arranged at intervals along the edge of the T-shaped track 4, and a plurality of pulleys 6 installed on the back of the hooks 2. The hooks 2 can move along the hanging plate 1 by inserting the pulleys 6 into the T-shaped track 4 through the openings 5. The above sliding mechanism is not only simple in structure, but also allows the hooks to be removed from and installed on the hanging plate at any opening, making assembly convenient.

[0028] The hook 2 includes a base 21, a cover plate 22 mounted on the base 21, and a connecting mechanism mounted on the cover plate 22 for connecting and fixing with emergency equipment. A channel 23 extending through to the side wall of the cover plate 22 is provided on the surface of the cover plate 22 facing the base 21. A pin hole 24 corresponding to the positioning hole 3 when the hook 2 passes through the channel 23 is provided on the base 21. A lock cylinder 25, capable of being inserted into the positioning hole 3, passes through the pin hole 24. One end of the lock cylinder 25 extends into the channel 23 and is fitted with a handle 26. Both ends of the handle 26 extend outwards from the cover plate 22 through the channel 23. A spring 210 is provided between the lock cylinder 25 and the cover plate 22. Under the elastic force of the spring 210, the handle 26 always tends to rest against the base 21 and cause the lock cylinder 25 to extend out of the pin hole 24 and insert into the hanging plate positioning hole 3. A latch 211 corresponding to the handle 26 is provided on the inner wall of the channel 23 on one side of the handle 26 when the lock cylinder 25 is inserted into the hanging plate positioning hole 3. When the lock cylinder 25 is inserted into the hanging plate positioning hole 3 and the handle 26 is rotated to latch into the latch 211, the lock cylinder 25 can maintain the locked posture of being inserted into the hanging plate positioning hole 3 so that the hook 2 is stably fixed to the hanging plate 2. When the handle 26 is rotated to disengage from the latch 211 and the handle 26 is pulled outward to disengage the lock cylinder 25 from the hanging plate positioning hole 3, the hook 2 can move relative to the hanging plate 1 again.

[0029] In this embodiment, the specific connection structure between the lock cylinder 25 and the handle 26 is as follows: A lug seat 27 symmetrically distributed on both sides of the pin hole 24 is provided at the end of the lock cylinder extending into the channel 23. A first radial mounting hole 28 coaxially arranged is provided in each of the two lug seats 27. A second radial mounting hole 262 penetrating the handle 26 along its width direction is provided in the middle of the handle 26. The two first radial mounting holes 28 correspond to the second radial mounting hole 262. Two radial pins 29 pass through the second radial mounting hole 262 from the first radial mounting holes 28 on both sides, thereby hingedly connecting the handle 26 and the lock cylinder 25 together via the two radial pins 29. This hinged structure design, on the one hand, allows for easy connection when the hook moves into place and the lock cylinder 25 is in the spring 2... After the lock cylinder 25 is inserted into the positioning hole 3 of the hanging plate under the action of the 10, during the process of rotating the handle 26 into the latch 211, the rotation of the handle 26 will not cause the axial position of the lock cylinder 25 in the pin hole to change. This ensures that the lock cylinder 25 can maintain the locked posture of being inserted into the positioning hole 3 of the hanging plate during the rotation of the handle 26, thereby improving the stability of use. On the other hand, when it is necessary to pull the handle 26 outward to make the lock cylinder 25 disengage from the positioning hole 3 of the hanging plate to unlock the hook 2, it can be ensured that when the handle 26 is pulled outward, the handle 26 can smoothly drive the lock cylinder 25 to move outward along the pin hole 24 axially to disengage from the positioning hole 3, and will not cause the lock cylinder 25 to get stuck in the pin hole 24 during the outward movement of the pin hole 24, further improving the stability of use.

[0030] In this embodiment, a locking block 7 is detachably installed on the inner wall of the channel 23 via connecting bolts. A gap is left between the locking block 7 and the base 21 for the handle 26 to be inserted. This gap forms a locking slot 211 in the channel for the handle 26 to rotate and be inserted. Since the locking block 7 is detachable, the size of the locking slot 211 can be adjusted synchronously by replacing and adjusting locking blocks of different sizes, so that the locking slot 211 can be adapted to handles 26 of different sizes, thus improving the applicability of the device. In this embodiment, the surface of the locking block 7 facing the base 21 is a first inclined surface 71 that gradually slopes downward towards the base 21 along the direction in which the handle rotates into the locking slot. A second inclined surface 261 is provided on the handle 26 that can cooperate and contact the first inclined surface 71 when the handle 26 rotates into the locking slot 211. Through the design of the first and second inclined surfaces, the handle 26 will become more and more tightly locked as it rotates into the locking slot 211, ensuring that the handle 26 is firmly locked in the locking slot 211 after it is inserted into the locking slot 211, further improving the stability of the device.

[0031] In this embodiment, the connecting mechanism includes: a hanging core 8; a groove 9 is provided on the surface of the cover plate away from the base 21; one end of the groove 9 extends upward to the side wall of the cover plate 22 to form an insertion port; a hanging plate 10 is installed at the opening of the groove 9; the upper end of the hanging plate 10 extends upward to the insertion port of the groove 9; a positioning notch extending downward to the lower part of the hanging plate is provided at the upper end of the hanging plate 10; the surface of the hanging core 8 is provided with a plurality of threaded holes 11 for connecting and fixing with emergency equipment, and fixing bolts matching the threaded holes 11; the hanging core 11... The cover plate 22 has symmetrically arranged positioning guide grooves 12 on both sides. The hanging core 8 is hung on the hanging plate 10 by aligning the two positioning guide grooves 12 and fitting them into the two side edges 13 of the positioning notch. A locking mechanism is provided on the cover plate 22. The locking mechanism can not only fix the hanging core 8 when it is hung on the hanging plate 10, but also unlock the hanging core 8 so that it can be removed from the hanging plate 10. The structure of the locking mechanism includes: a locking rod 14, which is hinged to the groove 9 of the cover plate 22 by a pin 15. The locking rods on both sides of the pin 15 are... The ends are a driving end and a locking end, respectively. The locking end of the locking rod 14 corresponds to the back of the hanging core 8 that is hung on the hanging plate 10. The driving end of the locking rod 14 extends out of the insertion port from the cover plate 22 and is equipped with a driving handle 16. A locking spring 17 is provided between the locking end of the locking rod 14 and the cover plate 22. Under the elastic force of the locking spring 17, the locking end of the locking rod 14 always tends to press the hanging core 8 tightly against the hanging plate 10. The above connection mechanism is simple. In practical applications, the hanging core 8 can be pre-installed through the threaded hole 11 and the matching fixing bolts. The device is fixedly installed on the emergency equipment. Then, the position of the hook 2 is moved. Since the emergency equipment is not yet installed on the hook 2 when it is moved, it is easier and more convenient to move the hook 2. After the hook 2 is moved into place along the hanging plate 1, the emergency equipment can then be hung on the hanging plate 10 of the hook 2 through the hanging core 8. The installation is convenient. When it is necessary to remove the emergency equipment from the hook 2, simply turn the drive handle 16 to release the locking end of the locking rod 14 from the hanging core 8, and the emergency equipment along with the hanging core can be removed from the hook. The operation is convenient.

[0032] After the emergency equipment has been hung on the hanging plate 1 via hook 2, when it is necessary to readjust the position of the emergency equipment on the hanging plate 1, first turn the handle 26 to disengage it from the latch 211, and then pull the handle 26 outward to disengage the lock cylinder 25 from the positioning hole 3 of the hanging plate. At this time, the hook 2 can move relative to the hanging plate 1 again. When the hook 2 moves along the T-shaped track 4 of the hanging plate 1 to the corresponding positioning hole 3, the lock cylinder 25 will extend out of the pin hole 24 and insert into the positioning hole 3 of the hanging plate under the elastic force of the spring 210. Then turn the handle 26 towards the latch 211 until the handle 26 is engaged in the latch 211. During the process of the handle 26 being turned into the latch 211, the design of the first and second inclined surfaces causes the handle 26 to tighten more and more as it rotates into the latch 211, ensuring that the handle 26 is firmly locked in the latch 211. After the handle 26 is locked in the latch 211, the lock cylinder can always maintain the locked posture of being inserted into the positioning hole of the hanging plate. In the locked posture, the lock cylinder will not change position in the axial direction with the positioning hole due to the bumps of the emergency vehicle, ensuring that the lock cylinder can always maintain the locked posture of being inserted into the positioning hole of the hanging plate. This effectively prevents the emergency equipment from being damaged due to the lock cylinder coming out of the positioning hole, thus improving the stability and safety of use. Example 2

[0033] The difference between Embodiment 2 and Embodiment 1 lies only in the connection mechanism; for example... Figure 14 As shown, the connection mechanism in this embodiment includes: a plurality of threaded holes 18 for connecting and fixing with the emergency equipment are provided on the surface of the cover plate 22 away from the base 21, and fixing bolts that match the threaded holes 18. In actual application, the emergency equipment is directly fixed on the cover plate 22 through the threaded holes 18 and the matching fixing threads, thereby being installed on the hook 2; when the emergency equipment needs to be removed, it can be easily removed by simply loosening and removing the fixing bolts.

[0034] The advantages of this invention are: (1) After the lock cylinder of the hook is inserted into the positioning hole of the hanging plate, the handle is rotated and locked into the slot, so that the lock cylinder can always maintain the locked posture of being inserted into the positioning hole of the hanging plate. In the locked posture, the lock cylinder will not change position with the positioning hole in the axial direction due to the bumps of the emergency vehicle, ensuring that the lock cylinder can always maintain the locked posture of being inserted into the positioning hole of the hanging plate, thereby effectively preventing the emergency equipment from being damaged due to the lock cylinder coming out of the positioning hole, and improving the stability and safety of use; (2) When the lock cylinder is inserted into the positioning hole of the hanging plate under the action of the spring, during the process of rotating the handle and locking it into the slot, the hand The rotation of the handle will not cause the lock cylinder to change its axial position in the pin hole, ensuring that the lock cylinder can always be inserted into the positioning hole of the hanging plate during the rotation of the handle, thereby improving the stability of use; (3) The structure on the hook for connecting with the emergency equipment is designed with a split connection structure. The hanging core can be pre-installed on the emergency equipment, and then the hanging core is hung on the hanging plate of the hook, so that the emergency equipment can be installed on the hook, which is convenient to install; and only by turning the drive handle to release the locking rod from the hanging core, the emergency equipment and the hanging core can be easily removed from the hook, which is very convenient to operate.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way.
