Description

Technical Field

[0001] This utility model relates to the field of seat fixing structure technology, specifically to the side seat fixing structure of an ambulance compartment. Background Technology

[0002] An ambulance is a vehicle used to transport patients. The word "AMBULANCE" on the vehicle is written backwards so that drivers in front can see the word "Ambulance" facing forward in their rearview mirror and quickly give way.

[0003] In the process of realizing this utility model, the inventors discovered that the following problems in the prior art have not been solved: the existing side seat fixing structure of the ambulance compartment mostly uses the seat to be integrally molded and fixedly connected. However, in some emergency situations, there are many injured people to be transported, and the seat cannot be unfolded to serve as a bed. Therefore, the existing seat fixing structure is not flexible and its practicality is not ideal. It is in urgent need of improvement. Therefore, we propose a side seat fixing structure for ambulance compartments. Utility Model Content

[0004] The purpose of this utility model is to provide a side seat fixing structure for ambulance compartments, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a side seat fixing structure for the ambulance compartment, including a seat plate a, a cushion placed on the top of the seat plate a, and limit rods fixedly installed on both sides of the rear wall of the seat plate a;

[0006] A seat plate b is placed on the front side of the seat plate a. The upper surfaces of both the seat plate a and the seat plate b are provided with slots. Both the seat plate a and the seat plate b are provided with several sets of uniformly arrayed grooves.

[0007] A stop block is placed in the groove, and an inner rod is fixedly installed on the inner side of the stop block. The inner rod moves through the seat plate a and the seat plate b respectively. A slot is opened on one side of the stop block.

[0008] Both sides of the seat plate a and seat plate b are provided with recessed platforms, and movable plates are placed in the recessed platforms. Insert rods are movably inserted through the side of the seat plate a and seat plate b near the recessed platforms, and there are a total of eight sets of insert rods. The insert rods are fixedly connected to the movable plates on the same side. Insert rods are inserted into the slots of the stop block.

[0009] The bottom of the seat cushion is fixedly equipped with a locking block, which is locked in the slot. It can be used in conjunction with components such as inner rods, blocks, and insert rods. During the use of the seat fixing structure, if there are too many injured people, the movable plate can be moved outward by applying force to disengage the insert rod from the slot of the block. At this time, the seat plate b is moved outward completely by applying force, and the slot of the block aligns with another set of insert rods. Then, the insert rod is reset inward so that it is locked in the slot. Multiple inner rods act as bed supports, allowing the mattress to be placed in the slot. At this time, the seat unfolds to form a temporary reclining bed. Compared with the existing method, it can increase the number of reclining positions in emergency situations.

[0010] As an optional solution to the technical solution of this application, a tension spring is sleeved on the outer side of the inner rod, and both the seat plate a and the seat plate b are fixedly connected to one end of the tension spring on the same side. The outer end of the tension spring is fixedly connected to the movable plate. It can be used in conjunction with components such as the tension spring and the movable plate. Since the tension spring exerts a force on the movable plate, the movable plate is in an inward state, and the insertion rod is inserted into the slot. This limiting method only requires force to complete the adjustment of the insertion rod, which is easy to adjust and use.

[0011] As an optional solution to the technical solution of this application, the bottom of the seat plate b is fixedly equipped with several sets of uniformly arrayed support rods. The bottom end of the support rods is rotatably connected to casters through a wheel frame. The seat plate b can be supported by multiple sets of support rods and casters, which facilitates the raising, lowering and moving of the seat plate b.

[0012] As an optional solution to the technical solution of this application, the top of the two sets of limiting rods is fixedly installed with a backrest, and a soft pad is fixedly installed on the backrest. The backrest and the soft pad can provide support for people in a sitting position, making the comfort more ideal.

[0013] As an optional solution to the technical solution of this application, the rear ends of the two sets of limiting rods are fixedly installed with positioning blocks, and positioning holes are opened on both sides of the positioning blocks. Through the positioning holes of the positioning blocks, the bolts can be moved through and screwed into the pre-set threaded structure on the inner wall of the carriage, so as to achieve a detachable and stable connection.

[0014] As an optional solution to the technical solution of this application, an indicator sticker is fixedly installed on one side of the backrest, and an oily film is integrally formed on the surface of the indicator sticker. The guide text on the indicator sticker can inform the operator of the corresponding seat folding and unfolding method, which is convenient for first-time users to understand and use.

[0015] As an optional solution to the technical solution of this application, the shape of the card block is adapted to the contour of the card slot, so that the components are adapted to the design, which can prevent the card block from shaking or slipping, and has a good stable positioning effect.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. The side seat fixing structure of the ambulance compartment of this utility model is equipped with inner rods, blocks, and insert rods. During the use of the seat fixing structure, if there are too many injured people, the movable plate can be moved outward by applying force to disengage the insert rod from the slot of the block. At this time, the seat plate b is moved outward completely by applying force, and the slot of the block aligns with another set of insert rods. Then, the insert rod is reset inward so that it is locked in the slot. Multiple inner rods act as bed supports, and the mattress is placed in the slot. At this time, the seat unfolds to form a temporary lying bed. Compared with the existing method, it can increase the number of lying positions in emergency situations.

[0018] 2. The side seat fixing structure of the ambulance compartment of this utility model is provided with a tension spring and a movable plate. Due to the force exerted by the tension spring on the movable plate, the movable plate is in an inward state, and the insertion rod is inserted into the slot. This limiting method can complete the adjustment of the insertion rod by applying force, which is easy to adjust and use. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figure 1-4This utility model provides a technical solution: a side seat fixing structure for an ambulance compartment, including a seat plate a1, a seat cushion 2 placed on top of the seat plate a1, and limit rods 3 fixedly installed on both sides of the rear wall of the seat plate a1. Positioning blocks 31 are fixedly installed at the rear ends of the two sets of limit rods 3, and positioning holes are provided on both sides of the positioning blocks 31. Bolts can be moved through the positioning holes of the positioning blocks 31 and screwed onto a pre-set threaded structure on the inner wall of the compartment, achieving a detachable and stable connection. Backrest plates 33 are fixedly installed on the top of the two sets of limit rods 3. A soft cushion is fixedly installed on the backrest 33, providing support for seated individuals and enhancing comfort. An indicator sticker 32 is fixedly installed on one side of the backrest 33, with an integrally formed oil-based film on its surface. The guide text on the indicator sticker 32 informs the operator of the corresponding seat folding and unfolding method, facilitating initial understanding and use. A seat plate b11 is placed in front of the seat plate a1. Both seat plates a1 and b11 have slots 12 on their upper surfaces, and several sets of... The seat plate b11 has a uniformly arranged groove 15. Several sets of uniformly arranged support rods 5 are fixedly installed at the bottom of the seat plate b11. The bottom ends of the support rods 5 are rotatably connected to casters 51 via wheel frames. The seat plate b11 is supported by multiple sets of support rods 5 and casters 51, facilitating its retraction and movement. A stop block 14 is placed inside the groove 15. An inner rod 13 is fixedly installed inside the stop block 14, and the inner rod 13 movably passes through both the seat plate a1 and the seat plate b11. A slot 16 is provided on one side of the stop block 14. Both sides of the seat plate a1 and the seat plate b11 have... There is a recessed platform 4, and a movable plate 41 is placed inside the recessed platform 4. Insert rods 42 are movably inserted through the side of the seat plate a1 and seat plate b11 near the recessed platform 4. There are eight sets of insert rods 42. The insert rods 42 are fixedly connected to the movable plate 41 on the same side. Insert rods 42 are inserted into the slot 16 of the stop block 14. A locking block 21 is fixedly installed at the bottom of the cushion 2. The locking block 21 is locked in the slot 12. The shape of the locking block 21 matches the contour of the slot 12, so that the components are adapted to the design. This can prevent the locking block 21 from shaking or sliding, and has a good stable locking effect.

[0027] In this technical solution, components such as inner rod 13, stop block 14, and insert rod 42 can be used together. During the use of the seat fixing structure, if there are too many injured people, the movable plate 41 can be moved outward by applying force, so that the insert rod 42 is disengaged from the slot 16 of the stop block 14. At this time, the seat plate b11 is moved outward completely by applying force, and the slot 16 of the stop block 14 is aligned with another set of insert rods 42. Then, the insert rod 42 is reset inward, so that the insert rod 42 is locked in the slot 16. Multiple inner rods 13 act as bed supports, so that the mattress is placed in the slot 12.

All components are general standard parts or parts known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional test methods.

[0031] When using the side seat fixing structure in the ambulance compartment, the side seat is placed inside the ambulance compartment and fixed to the side wall of the compartment by the positioning block 31. During this time, it can be used by personnel sitting on the seat cushion 2.

[0032] With the inner rod 13, stop 14, and insert rod 42 configured, during the use of the seat fixing structure, if there are too many injured people, the movable plate 41 can be moved outward by applying force, causing the insert rod 42 to disengage from the slot 16 of the stop 14. At this time, the seat plate b11 is moved outward completely by applying force, and the slot 16 of the stop 14 aligns with another set of insert rods 42. Then, the insert rod 42 is reset inward, so that the insert rod 42 is locked in the slot 16. Multiple inner rods 13 act as bed supports, allowing the mattress to be placed in the slot 12. At this time, the seat unfolds to form a temporary reclining bed. Compared with the existing method, it can increase the reclining position in emergency situations. With the tension spring 43 and movable plate 41 configured, the tension spring 43 applies force to the movable plate 41, causing the movable plate 41 to be in an inward state, and the insert rod 42 is inserted into the slot 16. This limiting method only requires applying force to complete the adjustment of the insert rod 42, making it easy to adjust and use.
