The casters of existing tool carts are usually equipped with brake devices, which can prevent the casters from slipping. However, the security is low and they cannot prevent theft or prying. They rely on friction to achieve braking and locking. With long-term use, they wear out severely, causing the locking to fail. In addition, they have poor vibration resistance and are prone to accidental slippage in vibrating environments.

[0003] Therefore, there is an urgent need for a secure, theft-proof, and pry-proof fastener for casters. Utility Model Content

[0024] Example 1:

[0025] In this embodiment, a fixing device for casters, such as... Figures 1 to 3 As shown, the lock includes a lock body and a lock body assembly. Specifically, the lock body is a U-shaped structure composed of a first parallel plate 1, a second parallel plate, and an end plate 3. The lock body is a welded structure with lower material and manufacturing costs. One end of the lock body is an open end of the U-shaped structure for the caster to enter the lock body. The lock body is detachably fixed to the ground by fasteners. The lock body assembly is connected between the first parallel plate 1 and the second parallel plate 2. The lock body assembly and the end plate 3 are respectively located at both ends of the lock body. A space 4 for limiting the caster is formed between the lock body assembly and the end plate 3. The lock body assembly has a key hole, and the lock body assembly is opened or closed by a key to open or close the open end of the lock body.

[0026] With this structure, the lock body is fixed to the ground. When in use, the casters are pushed into the receiving space 4, and the lock body assembly closes the open end of the lock body, thereby restricting the movement of the casters and effectively fixing them. The mechanical structure replaces the friction brake, avoiding the locking failure caused by wear of the friction brake. It is theft-proof and pry-proof. The U-shaped lock body distributes the force, has strong vibration resistance, prevents accidental slippage, and is more suitable for heavy loads.

[0027] As one specific implementation method of this embodiment, such as Figure 1 and Figure 3As shown, the lock body assembly includes a first lock handle 5 and a second lock handle 6. A first limiting hole 7 is provided on the first parallel plate 1, and a second limiting hole 8 is provided on the second parallel plate 2. The first limiting hole 7 and the second limiting hole 8 are used to install the first lock handle 5 and the second lock handle 6 respectively. One end of the first lock handle 5 is inserted into the first limiting hole 7, and one end of the second lock handle 6 is detachably connected to the other end of the first lock handle 5. The other end of the second lock handle 6 is inserted into the second limiting hole 8. The outer end of the first lock hole 5 or the second lock handle 6 is provided with a mechanism for unlocking. The outer end of the lock hole of the lock body assembly is the end of the first lock hole 5 or the second lock handle 6 that is away from the receiving space 4. By inserting a key into the lock hole, the connection between the first lock handle 5 and the second lock handle 6 can be locked or unlocked. After unlocking, the first lock handle 5 and the second lock handle 6 can be pulled out from the outside of the first parallel plate 1 and the second parallel plate 2 respectively, thereby opening the opening end of the floor lock body so that the caster can be pushed into the receiving space 4. Then, the first lock handle 5 and the second lock handle 6 can be inserted and locked to lock the caster and prevent the caster from moving.

[0028] In this embodiment, as Figure 3 As shown, one end of the first lock handle 5 is provided with a first protrusion 9, and the inner side of the first parallel plate 1 is provided with a first annular platform 10 concentric with the first limiting hole 7. The annular hole of the first annular platform 10 and the first limiting hole 7 form a stepped hole. The first protrusion 9 is inserted into the first limiting hole 7. The other end of the first lock handle 5 passes through the first annular platform 10 and is detachably connected to the second lock handle 6. The stepped surface of the stepped hole can limit the first protrusion 9 and prevent the first lock handle 5 from completely passing through the first limiting hole 7.

[0029] Furthermore, one end of the second lock handle 6 is provided with a second protrusion 11, and the inner side of the second parallel plate 2 is provided with a second annular platform 12 concentric with the second limiting hole 8. The annular hole of the second annular platform 12 is a stepped hole, and the large hole of the second annular platform 12 is connected to the second limiting hole 8. The second protrusion 11 is inserted into the second limiting hole 8 and the large hole of the second annular platform 12. The other end of the second lock handle 6 passes through the small hole of the second annular platform 12 and is detachably connected to the first lock handle 5. The stepped surface of the stepped hole of the second annular platform 12 forms a lateral limit on the second protrusion 11 to prevent the second lock handle 6 from completely passing through the second limiting hole 8.

[0030] In this embodiment, as Figure 1 and Figure 3 As shown, the bottom of the opposite sides of the first parallel plate 1 and the second flat plate are provided with a base plate 13. The base plate 13 is integrally formed or welded to the parallel plate. The base plate 13 is provided with mounting holes 14 for installing fasteners. There are multiple mounting holes 14, which are evenly arranged along a straight line. Fasteners are used to pass through the mounting holes 14 to fix and connect to the ground. The fasteners are preferably anchor bolts or screws.

[0031] As an optimization, such as Figure 1As shown, the first parallel plate 1 and the second flat plate have an arc-shaped chamfer 15 at the end away from the end plate 3. The arc-shaped chamfer 15 can prevent the sharp edges of the floor lock body from scratching the caster when the caster slides into the receiving space 4.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
