Description

Technical Field

[0001] This utility model relates to the field of mechanical movement technology, and more specifically, to a shock-absorbing brake caster. Background Technology

[0002] The invention of wheels made moving and transporting objects much easier, but wheels can only travel in a straight line, making it very difficult to change direction when moving heavy objects. This led to the development of wheels with steering mechanisms, which are what we call casters or swivel wheels. The advent of casters brought about a revolutionary change in the way people move objects, allowing for easy transport and movement in any direction, greatly improving efficiency. With the development of technology, the application of casters has become increasingly widespread, and almost every industry relies on them. Mechanical equipment is also trending towards multi-functionality and high utilization, making casters an indispensable component, such as casters with shock absorption functions.

[0003] However, current casters with shock absorption functions have complex structures, low assembly efficiency, and many parts, resulting in low product yield and service life.

[0004] In conclusion, how to reduce the structural complexity of shock-absorbing casters is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a shock-absorbing brake caster that reduces the number of parts in the shock-absorbing caster, which helps to shorten the assembly time and reduce the assembly difficulty.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A shock-absorbing brake caster includes:

[0008] A base, which is connected to the object used;

[0009] A shock absorber block, which is hinged to the base, and is equipped with casters for walking;

[0010] A shock absorber is located between the base and the shock absorber block, and is used to provide elastic support for the shock absorber block and the base.

[0011] Furthermore, the shock absorber is a plate-shaped bent piece, and both ends of the shock absorber are fixedly connected to the shock absorber block and the base, respectively.

[0012] Furthermore, the base includes a connecting part and a fixing part, arranged in an L-shaped structure. The shock-absorbing block is hinged to the connecting part, and the shock-absorbing component is located between the fixing part and the shock-absorbing block.

[0013] Furthermore, the fixing part is provided with a first connecting groove, the shock-absorbing block is provided with a second connecting groove, and the two ends of the shock absorber are respectively inserted into the first connecting groove and the second connecting groove to achieve the fixing of the shock absorber with the fixing part and the shock absorber.

[0014] Furthermore, one end of the shock absorber is provided with a bent connecting portion. When the connecting portion is inserted into the first connecting groove, the end of the shock absorber away from the connecting portion is inserted into the second connecting groove.

[0015] Furthermore, the shock absorber block is provided with a first limiting part, which is used to limit the minimum included angle between the fixing part and the shock absorber block.

[0016] Furthermore, the shock absorber block is provided with a second limiting part, which is used to limit the maximum included angle between the fixing part and the shock absorber block.

[0017] Furthermore, the present invention provides a base on the base, and the base and the base are rotatably connected by a connecting shaft.

[0018] Furthermore, in this invention, a rotating shaft is rotatably mounted on the shock-absorbing block, and the caster is mounted on the rotating shaft.

[0019] Furthermore, the caster is provided with a plurality of locking protrusions, which are evenly distributed along the axis of rotation. A locking groove is formed between two adjacent locking protrusions. A locking element is rotatably mounted on the shock-absorbing block. The locking element is provided with a locking pin, which enters the locking groove through the locking pin to restrict the rotation of the caster.

[0020] The shock-absorbing brake caster provided by this utility model has a base connected to the object being used, allowing the device to be applied to the object and enabling it to move. The shock-absorbing block is hinged to the base, allowing both the shock-absorbing block and the base to rotate. A shock-absorbing component located between the base and the shock-absorbing block provides elastic support for both. In other words, the shock-absorbing component creates an elastic support between the base and the shock-absorbing block. The hinged base and shock-absorbing block, achieved by connecting the two ends of the elastic component between the shock-absorbing block and the base, result in a miniaturized product, reducing the number of overall caster components and extending its service life.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] The core of this utility model is to provide a shock-absorbing brake caster, which reduces the number of parts in the shock-absorbing caster, thus reducing the assembly time and assembly difficulty.

[0032] Please refer to Figure 2 A shock-absorbing brake caster includes a base 1, a shock-absorbing block 2, and a shock-absorbing component 3. The base 1 is connected to the object to be used, the shock-absorbing block 2 is hinged to the base 1, and a caster 7 for walking is installed on the shock-absorbing block 2. The shock-absorbing component 3 is located between the base 1 and the shock-absorbing block 2 and is used to provide elastic support force for the shock-absorbing block 2 and the base 1.

[0033] Optionally, in some embodiments, the damping block 2 is provided with a U-shaped opening, and the base 1 is placed inside the U-shaped opening, and the damping block 2 and the base 1 are hinged through the connecting shaft 5.

[0034] In the above embodiment, the base 1 is a rod-shaped structure. Specifically, the bottom of the base 1 is provided with a narrowed connecting part 102 for inserting into the U-shaped opening of the shock absorber 2 to achieve its hinge.

[0035] Alternatively, in some embodiments, the caster 7 may be a rubber wheel.

[0036] Optionally, in some embodiments, the shock absorber 3 may be a workpiece or structure with elastic deformation function. Specifically, it may be a structure such as a spring or elastic sheet, or a workpiece made of a material with elastic deformation function such as a rubber block or silicone block.

[0037] In use, the base 1 is connected to the object to be used, so that the device can be applied to the object and the caster 7 enables its walking function. The shock absorber 2 is hinged to the base 1 so that the shock absorber 2 and the base 1 can rotate. The shock absorber 3 is located between the base 1 and the shock absorber 2. The shock absorber 3 is used to provide elastic support force between the shock absorber 2 and the base 1. That is, the shock absorber 3 creates an elastic support force between the base 1 and the shock absorber 2. The hinged base 1 and the shock absorber 2, that is, by connecting the two ends of the elastic element between the shock absorber 2 and the base 1, achieves product miniaturization, reduces the number of overall structural components of the caster 7, and extends service life.

[0038] Please refer to Figure 2 In some embodiments, the shock absorber 3 is a plate-shaped bent part. The two ends of the shock absorber 3 are fixedly connected to the shock absorber block 2 and the base 1, respectively. That is to say, the shock absorber 3 is a bent part with elastic deformation function. By its bending angle, it has elastic support force, thereby realizing elastic support for the shock absorber block 2 and the base 1, and thus playing a shock absorption role. At the same time, the bent part is easy to process and install, which can further reduce the difficulty of device assembly.

[0039] Optionally, in some embodiments, the damping element 3 may adopt a multi-layered bending structure, and the elastic coefficient of the damping element 3 may be specified according to the actual required damping requirements.

[0040] Optionally, in some embodiments, the shock absorber 3 may be made of spring steel, stainless steel, engineering thermoplastic materials, etc.

[0041] Optionally, in some embodiments, the two ends of the shock absorber 3 can be fixedly connected to the shock absorber block 2 and the base 1 by bolts or clips.

[0042] Please refer to Figure 2In some embodiments, the base 1 includes a connecting part 102 and a fixing part 101, arranged in an L-shaped structure. The damping block 2 is hinged to the connecting part 102, and the damping member 3 is located between the fixing part 101 and the damping block 2. That is, the base 1 includes at least a connecting part 102 and a fixing part 101, and the connecting part 102 and the fixing part 101 are distributed in an L-shaped structure so that the included angle between the fixing part 101 and the damping block 2 is less than 90 degrees, so as to facilitate the installation of the damping member 3.

[0043] Optionally, in some embodiments, the base 1 further includes a mounting portion located on the side of the fixing portion 101 away from the connecting portion 102, for mounting in conjunction with the object used.

[0044] Please refer to Figure 1 In some embodiments, the fixing part 101 is provided with a first connecting groove 103, and the shock absorber block 2 is provided with a second connecting groove 201. The two ends of the shock absorber 3 are respectively inserted into the first connecting groove 103 and the second connecting groove 201 to fix the shock absorber 3 to the fixing part 101 and the shock absorber block 2. That is, the two ends of the shock absorber 3 are fixed by the two connecting grooves, thereby fixing the position of the shock absorber 3. Bolts are not used, which helps to reduce the number of workpieces used in the assembly of the device and further improves the assembly efficiency.

[0045] Optionally, in some embodiments, the first connecting groove 103 and the second connecting groove 201 are both interference-fitted with both ends of the shock absorber 3 to improve its fixation firmness.

[0046] Optionally, in some embodiments, one end of the shock absorber 3 is provided with a bent connecting portion 102. When the connecting portion 102 is inserted into the first connecting groove 103, the end of the shock absorber 3 away from the connecting portion 102 is inserted into the second connecting groove 201. That is, one end of the shock absorber 3 is bent at a preset angle. By utilizing the angle difference between the connecting portion 102 and the end of the shock absorber 3, and by cooperating with the connecting portion 102, the position of the shock absorber 3 is fixed, which can effectively prevent the shock absorber 3 from shifting.

[0047] Optionally, in some embodiments, both ends of the shock absorber 3 can be made into bent connecting portions 102 to further improve its connection stability.

[0048] Optionally, in some embodiments, both the first connecting groove 103 and the second connecting groove 201 adopt through holes along the width direction of the shock absorber 2, thereby increasing the convenience of installation.

[0049] In the above embodiment, both the first connecting groove 103 and the second connecting groove 201 adopt through holes along the width direction of the shock absorber 2 and have extension holes at the bottom of the through holes. The width of the extension holes is smaller than the width of the shock absorber 2 and the fixing part 101, and the width of the shock absorber 2 is less than or equal to the width of the extension holes. During installation, the shock absorber 2 can be inserted into the first connecting groove 103 and the second connecting groove 201 from the side. After the shock absorber 3 enters the first connecting groove 103 and the second connecting groove 201, the shock absorber 3 will enter the extension holes, which can further improve the firmness of the shock absorber 3 and facilitate installation.

[0050] Please refer to Figure 2 In some embodiments, the shock absorber 2 is provided with a first limiting part 202. The first limiting part 202 is used to limit the minimum included angle between the fixing part 101 and the shock absorber 2. That is, the first limiting part 202 limits the maximum angle of rotation of the shock absorber 2 toward the fixing part 101. That is, when the weight of the object used in the device is large, the first limiting part 202 can make the shock absorber 2 and the fixing part 101 contact, thereby ensuring its effective support function.

[0051] Optionally, in some embodiments, the first limiting part 202 is a protrusion provided on the shock absorber 2, which can be fixed by integral molding with the shock absorber 2.

[0052] In other embodiments, the first limiting part 202 may be a bolt, which is threaded onto the shock absorber 2. During use, the length of its protrusion can be adjusted by turning the bolt, thereby controlling the limiting distance of the first limiting part 202 and improving the versatility of the device.

[0053] Optionally, in some embodiments, a buffer is provided at the contact position between the first limiting part 202 and the shock absorber 2. The buffer can be made of materials such as rubber or silicone, so that the first limiting part 202 and the shock absorber 2 make elastic contact, reducing collisions and noise during the shock absorption support process, and also improving its shock absorption effect.

[0054] Please refer to Figure 2 In some embodiments, the shock absorber 2 is provided with a second limiting part 203. The second limiting part 203 is used to limit the maximum included angle between the fixing part 101 and the shock absorber 2. That is, by limiting the maximum angle of rotation of the shock absorber 2 in the direction away from the fixing part 101 by the first limiting part 202, it can prevent the device from being lifted and not subjected to force, thus preventing excessive rotation.

[0055] Optionally, in some embodiments, the second limiting part 203 is a protrusion provided on the shock absorber 2, which can be fixed by integral molding with the shock absorber 2.

[0056] In other embodiments, the second limiting part 203 may be a bolt, which is screwed onto the shock absorber 2. During use, the length of its protrusion can be adjusted by screwing the bolt, thereby controlling the limiting distance of the second limiting part 203 and improving the versatility of the device.

[0057] Please refer to Figure 1 In some embodiments, the base 1 is provided with a base 4, and the base 4 and the base 1 are rotatably connected by a connecting shaft 5. That is, the connecting shaft 5 acts as a rotatable connector to realize the rotatable connection between the base 4 and the base 1.

[0058] Optionally, in some embodiments, the base 1 is provided with a shaft groove, and the connection between the base 4 and the base 1 can be achieved by inserting the connecting shaft 5 into the shaft groove.

[0059] In the above embodiment, the connecting shaft 5 is detachably installed in the shaft groove.

[0060] Please refer to Figure 4 In some embodiments, a rotating shaft 6 is rotatably mounted on the shock absorber 2, and a caster 7 is mounted on the rotating shaft 6. A bearing is provided between the rotating shaft 6 and the shock absorber 2 to reduce wear on the rotating connection.

[0061] Please refer to Figure 6 In some embodiments, the caster 7 is provided with a plurality of locking protrusions 8, which are evenly distributed along the axis of the rotating shaft 6. A locking groove 9 is formed between two adjacent locking protrusions 8. A locking member 10 is rotatably mounted on the shock absorber 2. The locking member 10 is provided with a locking pin 11, which enters the locking groove 9 through the locking pin 11 to restrict the rotation of the caster 7.

[0062] In the above embodiment, the locking protrusion 8 includes a square column portion near the center and a cylindrical portion on the outer periphery of the circle, thereby increasing the smoothness of the locking post 11 in the initial stage of movement, and the smaller opening prevents the locking member 10 from accidentally contacting and forming unnecessary locking; the larger inner locking space allows for a small amount of movement space after the locking post 11 enters the locking groove 9 to achieve the locking effect, avoiding structural damage caused by hard contact between the locking post 11 and the locking protrusion 8.

[0063] Optionally, in some embodiments, the shock absorber 2 is provided with a guide groove, and the locking pin 11 can slide in the guide groove to support the rotation of the locking member 10. The locking pin 11 of the locking member 10 is located at the opening of the guide groove. The locking pin 11 and the locking protrusion 8 do not interfere with each other. When locking is required, the upper end of the locking member 10 is pressed, so that the locking pin 11 slides inward in the guide groove, that is, slides towards the center of the array of locking protrusions 8. The two ends of the locking pin 11 slide into the locking groove 9 to lock the caster 7.

[0064] Optionally, in some embodiments, the bottom of the guide groove is provided with a through U-shaped opening, so that when the locking pin 11 fails to disengage while in the locked state, it can be disengaged by an external device through the opening.

[0065] In other words, the key point of this utility model is that the shock absorber 2 is hinged to the base 1 so that the shock absorber 2 and the base 1 can rotate. The shock absorber 3 is located between the base 1 and the shock absorber 2. The shock absorber 3 is used to provide elastic support force for the shock absorber 2 and the base 1. That is, the shock absorber 3 makes there an elastic support force between the base 1 and the shock absorber 2. The hinged base 1 and the shock absorber 2, that is, by connecting the two ends of the elastic element between the shock absorber 2 and the base 1, realizes the miniaturization of the product, reduces the number of overall structural components of the caster 7, and extends the service life.
