  • FIG. 2 is an assembled, side cross-sectional view of the locking assembly of FIG. 1 , the locking assembly assembled with a second object.
  • FIG. 3 is an assembled, side cross-sectional view of a locking assembly according to a second preferred embodiment of the present invention.
  • FIG. 4 is an abbreviated, side cross-sectional view of a conventional locking assembly fixing two objects together.
  • the locking assembly 20 is preferably used to fasten at least two metal sheets or plastic sheets together such as electrical circuit boards, electronic devices, and other computer components.
  • the locking assembly 20 includes a fastener 22 , a sleeve 24 , and a resilient member 26 .
  • the sleeve 24 is provided for holding and guiding the fastener 22 .
  • the fastener 22 is essentially a screw that includes a head portion 226 , a neck portion 224 , and a threaded portion 222 .
  • the sleeve 24 is substantially a cylinder, which defines a through hole 242 along a center axis of the sleeve 24 .
  • the through hole 242 includes three connecting parts in a following order: a first part 2422 , a second part 2424 , and a third part 2426 .
  • the sleeve 24 further includes a restricting portion 244 extending out from an inner surface of the through hole 242 between the second part 2424 and the third part 2426 .
  • the restricting portion 244 defines an inner screw threading.
  • the threaded portion 222 of the fastener 22 defines an outer screw threading to engage with the inner screw threading of the restricting portion 244 . Therefore, the threaded portion 222 can be screwed through the restricting portion 244 correspondingly.
  • the locking assembly 20 is used to fasten a first object (not shown) and a second object 28 .
  • the threaded portion 222 of the fastener 22 is driven to pass through the restricting portion 244 , and finally screwed into a threaded hole of the first object (not shown).
  • the restricting portion 244 is configured for preventing the threaded portion 222 to slide out, thus also preventing the fastener 22 to slide out of the sleeve 24 .
  • a depth of the through hole 242 of the sleeve 24 is configured deeper than the length of the fastener 22 , for protecting the fastener 22 better.
  • a maximum outer diameter of the threaded portion 222 of the fastener 22 is larger than that of the neck portion 224 , and smaller than that of the head portion 226 .
  • An inner diameter of the first part 2422 of the through hole 242 is larger than the outer diameter of the head portion 226 .
  • An inner diameter of the second part 2424 of the through hole 242 is smaller than the outer diameter of the head portion 226 , but larger than the largest of the outer diameters of the neck portion 224 and the threaded portion 222 .
  • An inner diameter of the third part 2426 of the through hole 242 is smaller than that of the second part 2424 .
  • the inner diameter of the third part 2426 is larger than or equal to the outer diameter of the threaded portion 222 of the fastener 22 .
  • the head portion 226 of the fastener 22 can be held in the first part 2422 of the through hole 242 of the sleeve 24 .
  • the resilient member 26 is a spring.
  • An outer diameter of the resilient member 26 is larger than a minimum diameter of the restricting portion 244 .
  • An inner diameter of the resilient member 26 is larger than the diameters of the threaded portion 222 , but smaller than the diameter of the head portion 226 of the fastener 22 .
  • the resilient member 26 is disposed in the through hole 242 of the sleeve 24 above the restricting portion 244 .
  • the threaded portion 222 of the fastener 22 pass through the resilient member 26 .
  • opposite ends of the resilient member 26 resists the head portion 226 of the fastener 22 and the restricting portion 244 of the sleeve 24 correspondingly.
  • the resilient member 26 produces a force pushing the fastener 22 upwards out of the sleeve 24 , but the restricting portion 244 would block the fastener 22 from sliding out of the sleeve 24 .
  • This configuration allows re-assembling the locking assembly 20 quickly.
  • the resilient member 26 can be omitted.
  • the sleeve 24 further includes a flange portion 246 extending out from an outer surface of the sleeve 24 adjacent to a distal end of the first part 2422 of the through hole 242 .
  • the sleeve 24 may further define a latching slot 248 in the outer surface adjoining the flange portion 246 .
  • the second object 28 defines an opening (not labeled). A diameter of the flange portion 246 is larger than that of the opening of the second object 28 .
  • the sleeve 24 with the fastener 22 partially passes through the opening of the second object 28 .
  • the second object 28 is attached to the assembly at the latching slot 248 .
  • the second object 28 is firmly held by the flange portion 246 of the sleeve 24 , such that the first object (not shown) and the second object 28 are fastened together.
  • the latching shot 248 of the sleeve 24 can be omitted as long as the second object 28 defines a hole to contain the sleeve 24 correspondingly.
  • the depth of the through hole 242 of the sleeve 24 can be equal to or smaller than the length of the fastener 22 .
  • any two parts of the first part 2422 , the second part 2424 and the third part 2426 of the through hole 242 can be omitted.
  • a second preferred embodiment of the present invention is described, in detail, in following paragraphs.
  • the locking assembly 30 includes a fastener 32 and a sleeve 34 .
  • the fastener 32 includes a head portion 326 , a neck portion 324 , and a threaded portion 322 .
  • the locking assembly 30 is similar in principle to the locking assembly 20 of the first embodiment.
  • the sleeve 34 defines a through hole 342 and further includes a restricting portion 344 extending from an inner surface of one end of the through hole 342 . After the threaded portion 322 of the fastener 32 is driven to pass through the restricting portion 344 of the sleeve 34 , the restricting portion 344 can block the locking portion from sliding out of the sleeve 34 .
  • the restricting portion 344 can be formed at opposite end of the inner surface of the through hole 342 .
  • the threaded portion 322 passes through the through hole 342 in a direction from one end of the through hole 342 without restricting portion 344 to the opposite end of the through hole 342 having restricting portion 344 .
  • the fastener 22 , 32 can be replaced by any other locking members, the locking member having a locking portion and a neck portion connected to the locking portion.
  • the lock portion can be one of latches or latching grooves that firmly mates with corresponding structures defined in object that will be fastened.
  • the restricting portion 244 , 344 is replaced by one of elastic hooks or protruding ribs. For example, if the restricting portion is an elastic hook defined on inner surface of the through hole of the sleeve, the locking portion of the locking member can be pressed to pass through the elastic hook, but restricted by a hook of the elastic hook backward.
  • the locking portion can pass through the protruding rib when the protruding rib is heated to expand.
  • the locking portion of the locking member is firstly to pass through the restricting portion, then a plurality of dots are formed on the restricting portions for restricting the locking member backward.
