Technical Field
[0001] The utility model relates to an upper pull belt fixing structure of a child safety seat. Background Art
[0002] With the continuous development of modern society, people's living standards are constantly improving, and people are paying more and more attention to the basic necessities of life. Especially in recent years, people's enthusiasm for travel has not decreased but increased. People who travel mainly with their families usually choose to travel by car. Families with younger children usually choose to install child safety seats in the car. Child safety seats are a kind of equipment used to protect the safety of children in vehicles. With the development of the automobile industry, various countries have also introduced relevant laws and regulations, requiring that children within a certain age or weight range must use special child safety seats. In the design of child safety seats, the upper pull belt fixing structure is a key part, which can ensure that the safety seat is tightly and correctly fixed on the car seat, thereby protecting the safety of children during driving.
[0003] Traditional child safety seats are usually fixed with seat belts or the LATCH system. The seat belt system uses the vehicle's own seat belt to tighten the child safety seat to the seat. The disadvantage is that it may be complicated to install, and not everyone can install it correctly. The LATCH system includes two anchor points to fix the bottom and one anchor point to fix the top, which is called the upper strap. The upper strap is usually fixed with a matching fixing behind the child safety seat to connect to the fixing point of the rear seat of the vehicle. In actual situations, the upper strap is usually fixed behind the child safety seat. In order to ensure the fixing strength, some manufacturers completely lock the upper strap at the bottom of the seat, which makes it difficult to remove the upper strap in some necessary situations, and cannot ensure flexibility while providing necessary safety. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a top strap fixing structure of a child safety seat to solve the problems in the above-mentioned background technology.
[0005] Based on the technical problems existing in the background technology, the utility model proposes a top strap fixing structure of a child safety seat, comprising a top strap assembly installed on a safety seat body, a base is provided at the bottom of the safety seat body, and a base support frame is provided at the bottom of the base;
[0006] The upper end of the safety seat body is provided with a body belt slot;
[0007] A base belt slot is provided at the top of one side of the base support frame, a fixed beam is provided inside the same side of the base belt slot, a fixed iron is provided on the fixed beam, a fixed iron barb is provided at the upper end of the fixed iron, and a fixed iron belt slot corresponding to the position of the base belt slot is provided on the fixed iron barb;
[0008] The upper pull belt assembly includes an upper pull belt connecting belt, one end of the upper pull belt connecting belt is connected to an upper pull belt adjuster, and the other end is curled and fixed to form an upper pull belt locking hole. The upper pull belt locking hole passes through the main body belt slot, the base belt slot and the fixed iron belt slot in sequence and a fixed shaft is installed inside. The fixed shaft locks the upper pull belt locking hole in the fixed iron barb.
[0009] Preferably, the sizes of the main body belt slot, the base belt slot and the fixed iron belt slot should be at least larger than the cross-sectional size of the upper pull belt connecting belt, and smaller than the cross-sectional size of the upper pull belt locking hole when the fixed shaft is inserted.
[0010] Preferably, the length of the fixed shaft should be at least greater than the accommodating length of the upper drawstring locking hole, and the size that can be accommodated by the upper drawstring locking hole should correspond to the size of the fixed shaft.
[0011] Preferably, the fixing iron barb is arc-shaped, and the inner dimensions thereof correspond to the overall dimensions of the locking hole of the upper pull belt and the fixing shaft.
[0012] Preferably, the overall length of the upper pull belt connecting belt should at least be greater than the distance between the belt passing groove of the main body and the belt passing groove of the fixed iron.
[0013] Preferably, the main body belt groove is arranged at the top middle position of the safety seat body, and a belt beam is further arranged at one side of the main body belt groove.
[0014] Compared with the prior art, the upper strap fixing structure of a child safety seat proposed by the present invention adopts the above technical solution and achieves the following technical effects:
[0015] 1. In the utility model, after the upper pull belt locking hole of the upper pull belt assembly passes through the body belt slot, the base belt slot and the fixed iron belt slot, the fixed shaft is inserted into the upper pull belt locking hole, so that it cannot pass through the slot body passed through in front, so that the upper pull belt assembly is fixed. This fixing method is simple to operate, and the entire upper pull belt connecting belt can be pulled out by simply taking out the fixed shaft for disassembly. In the event of a safety accident, it can be quickly disassembled, which greatly shortens the rescue time and reduces the possibility of safety accidents.
[0016] 2. The locking hole of the upper pull belt is installed inside the fixed iron barb buckle. The fixed iron belt slot will limit the upper pull belt. If the fixed iron breaks, the upper pull belt will be separated from the fixed iron barb buckle. The base belt slot set on the outside will also limit the upper pull belt. The double limit can ensure that the upper pull belt still has safety protection capabilities in case of emergencies. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0024] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0025] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0026] Reference Figure 1-6 The utility model provides a top strap fixing structure of a child safety seat, comprising a top strap assembly 2 mounted on a safety seat body 1, a base 3 is provided at the bottom of the safety seat body 1, and a base support frame 4 is provided at the bottom of the base 3;
[0027] Specifically, a body belt slot 11 is provided at the upper end of the safety seat body 1;
[0028] Specifically, a base belt slot 41 is provided at the top of one side of the base support frame 4, a fixed beam 5 is provided inside the same side of the base belt slot 41, a fixed iron 51 is provided on the fixed beam 5, a fixed iron barb 52 is provided at the upper end of the fixed iron 51, and a fixed iron belt slot 53 corresponding to the position of the base belt slot 41 is provided on the fixed iron barb 52;
[0029] Specifically, the upper pull strap assembly 2 includes an upper pull strap connecting strap 21, one end of which is connected to an upper pull strap adjuster 22, and the other end is curled and fixed to form an upper pull strap locking hole 23. The upper pull strap locking hole 23 passes through the main body belt slot 11, the base belt slot 41 and the fixed iron belt slot 53 in sequence and a fixed shaft 6 is installed inside. The fixed shaft 6 locks the upper pull strap locking hole 23 in the fixed iron barb 52.
[0030] In this embodiment, the upper pull strap locking hole 23 at one end of the upper pull strap connecting strap 21 in the upper pull strap assembly 2 passes through the main body belt slot 11, the base belt slot 41 and the fixed iron belt slot 52 and finally reaches the buckle position of the fixed iron 51. At this time, the fixed shaft 6 is inserted into the upper pull strap locking hole 23 to confine it in the buckle position of the fixed iron 51, thereby realizing the fixation of the overall upper pull strap assembly 2. This fixing method mainly relies on the fixed shaft 6 for fixing, and relies on the fixed iron belt slot 53 for limiting at the same time. The installation and disassembly are simple, and the double limiting of the base belt slot 41 and the fixed iron belt slot 53 makes the fixation of the upper pull strap more reliable.
[0031] Reference Figure 3-6The size of the main body belt slot 11, the base belt slot 41 and the fixed iron belt slot 53 should be at least larger than the cross-sectional size of the upper pull belt connecting belt 21 to ensure that the upper pull belt locking hole 23 can pass through the slot smoothly, and smaller than the cross-sectional size of the upper pull belt locking hole 23 when the fixed shaft 6 is inserted to prevent one end of the upper pull belt from falling off during use.
[0032] Specifically, the length of the fixed shaft 6 should be at least greater than the accommodating length of the upper pull strap locking hole 23, and the size that the upper pull strap locking hole 23 can accommodate should correspond to the size of the fixed shaft 6, so that the fixed shaft 6 has sufficient length to be fixed by the body and ensure the stability of the connection after passing through the locking hole.
[0033] Specifically, the fixed iron barb 52 is arc-shaped to reduce friction and avoid damage to the upper pull belt during the passing or locking process, and the internal size corresponds to the overall size of the upper pull belt locking hole 23 and the fixed shaft 6. The fixed iron barb 52 is inward-curled to prevent the fixed shaft 6 and the upper pull belt locking hole 23 from naturally sinking and falling off. This design is to ensure that the upper pull belt can smoothly pass through the fixed iron belt slot 53 and form a stable combination with the fixed shaft 6 when locked.
[0034] Specifically, the overall length of the upper pull belt connecting belt 21 should be at least greater than the distance between the main body belt slot 11 and the fixed iron belt slot 53 to ensure that the safety seat can still be used normally in various height adjustment states.
[0035] Specifically, the main body belt slot 11 is arranged at the top middle position of the safety seat body 1 , and a belt beam 12 is further arranged at one side of the main body belt slot 11 .
[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
