Description

Technical Field

[0001] This utility model belongs to the field of furniture caster technology, and in particular relates to a novel furniture caster. Background Technology

[0002] Casters are a general term that includes swivel casters, fixed casters, and swivel casters with brakes. Swivel casters, also known as universal wheels, have a structure that allows them to rotate 360 ​​degrees; fixed casters, also called directional casters, do not have a rotating structure and cannot turn. Usually, the two types of casters are used together. For example, a handcart typically has two fixed casters at the front and two swivel casters near the push handle at the back.

[0003] In the prior art, the structure of furniture casters is generally simple. The locking mechanism of furniture casters usually uses brake pads for locking. However, brake pads are prone to loosening under strong external force, which makes it impossible to lock the caster. Therefore, a new type of furniture caster is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of furniture caster to solve the existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

The locking frame is welded to the front surface of the two mounting plates. The locking frame has a concave plate structure. A first through hole is formed on one surface of the locking frame, and a locking rod is slidably installed inside the first through hole. A connecting plate is welded to the circumferential side of one end of the locking rod. A return spring is installed between one surface of the connecting plate and one inner surface of the locking frame. The return spring is wrapped around the circumference of the locking rod, facilitating the fixation of the caster body when the furniture does not need to be moved, thus improving the locking effect on the caster body. Sliding grooves are formed on both opposite surfaces of the connecting plate, and positioning rods are slidably installed inside each of the two sliding grooves. Connecting springs are installed between one end of each of the two positioning rods and the inside of the two sliding grooves, allowing the locking rod to be pulled out and its position fixed when the furniture needs to be moved, preventing interference with the rolling of the caster body.

[0007] Furthermore, the other end of the locking rod extends to the outside of the locking frame, and a pull plate is welded to the other end of the locking rod. The other ends of the two positioning rods extend to the outside of the slide groove.

[0008] Furthermore, the locking frame has a second through hole on each of its two opposite surfaces, and the positions of the two second through holes correspond to the positions of the two positioning rods.

[0009] Furthermore, the other ends of the two positioning rods extend to the outside of the locking frame through the second through hole, and the positioning rods are slidably connected to the second through hole.

[0010] Furthermore, a connecting shaft is installed between the two mounting plates, and a caster body is rotatably mounted on the circumferential side of the connecting shaft. The caster body has several snap-fit ​​holes on its circumferential side, and both ends of the connecting shaft pass through one surface of the two mounting plates respectively.

[0011] Furthermore, both ends of the connecting shaft extend to the outside of the two mounting plates respectively, the peripheral side of the connecting shaft is slidably connected to the mounting plates, and both ends of the connecting shaft are screwed with mounting bolts.

[0012] Furthermore, a connecting base is welded to the upper surface of the caster frame, a connecting rotating rod is welded to the upper surface of the connecting base, and a bearing base is rotatably mounted on the upper end of the connecting rotating rod.

[0013] Furthermore, two dampers are welded to the upper surface of the bearing base, and a fixing plate is welded to the upper surface of the two dampers. Fixing holes are opened on the periphery of the upper surface of the fixing plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, through the structure of locking rod, snap-fit ​​hole and return spring, facilitates the fixing of the position of the caster body when the furniture does not need to be moved, thereby improving the locking effect of the caster body. At the same time, through the structure of connecting plate, connecting spring and positioning rod, it is easy to pull out the locking rod and fix its position when the furniture needs to be moved, so as to avoid affecting the rolling of the caster body.

[0016] 2. This utility model uses a damper structure to facilitate the buffering of impacts on furniture during use, reduce pressure on the casters, and improve the stability of the furniture during use.

The locking frame 2 has a concave plate structure. A first through hole 201 is opened on one surface of the locking frame 2. A locking rod 202 is slidably installed inside the first through hole 201. A connecting plate 204 is welded to the circumferential side of one end of the locking rod 202. A return spring 205 is installed between one surface of the connecting plate 204 and one inner surface of the locking frame 2. The return spring 205 is wound around... Around the locking rod 202, the position of the caster body 103 can be fixed when the furniture does not need to be moved, thus improving the locking effect of the caster body 103. The two opposite surfaces of the connecting plate 204 are provided with sliding grooves 206. Positioning rods 207 are slidably installed inside the two sliding grooves 206. One end of the two positioning rods 207 is respectively installed with a connecting spring 208 between it and the inside of the two sliding grooves 206. This allows the locking rod 202 to be pulled out and fixed in position when the furniture needs to be moved, thus avoiding affecting the rolling of the caster body 103.

[0028] The other end of the locking rod 202 extends to the outside of the locking frame 2. A pull plate 203 is welded to the other end of the locking rod 202. The other ends of the two positioning rods 207 extend to the outside of the slide groove 206. The two opposite surfaces of the locking frame 2 are provided with second through holes 209.

[0031] Please see Figures 1-4As shown, this utility model is a new type of furniture caster. Its usage is as follows: First, install fixing bolts inside the fixing hole 5 to fix the fixing plate 4 to the furniture. When it is necessary to lock the caster body 103, first push the two positioning rods 207 to disengage them from the second through hole 209. At this time, the connecting plate 204 and the locking rod 202 are in a movable state. Then, the return spring 205 drives the locking rod 202 to move, causing the locking rod 202 to engage with the snap-fit ​​hole 105, thus locking the caster body 103. When the caster needs to be moved, the pull plate 203 is pulled to move the locking rod 202 outward, causing the return spring 205 to compress and deform. When the locking rod 202 moves, it drives the connecting plate 204 to move. The connecting plate 204 drives the two positioning rods 207 to slide inside the locking frame 2. When the two positioning rods 207 move to the second through hole 209, the spring 208 connected inside the slide groove 206 resets, pushing one end of the two positioning rods 207 to the outside of the second through hole 209. At this time, the locking rod 202 and the connecting plate 204 are in a fixed state, which does not affect the rolling of the caster body 103.
