Abstract
The utility model discloses a kind of anti-lost screw attaching/detaching apparatus, comprise screw, upper shell and upper shell, upper shell is provided with groove, the bottom of groove offers via hole, upper shell is arranged at below the groove of upper shell, lower house is inverted T font, lower house is provided with longitudinal container cavity, and container cavity comprises the thread cavity below the cavity of epimere and cavity; Screw passes from via hole and inserts container cavity.The utility model in use, do not need screw to take out completely, namely need not take out in product completely, stay on product and can open upper shell and lower house, can be absolute prevent screw loss in use, and then reduce the maintenance of user and use cost.
Description
Technical field
The utility model relates to hardware component, is specifically related to a kind of anti-lost screw attaching/detaching apparatus.
Background technology
The existing mounting structure fixing by screw; when manufacturing the dismounting of maintenance; all need a screw entirely to pull down and just can open housing; then screw is placed on one side; until screw is installed during assembling, like this in whole operating process, screw is very easily lost again; particularly in long installation and maintenance process, workmen also often can forget screw placement in where.Generally speaking, existing product can cause the loss of very large time cost and financial cost.
Utility model content
Goal of the invention: the purpose of this utility model is to solve the deficiencies in the prior art, provides a kind of anti-lost screw attaching/detaching apparatus.
Technical scheme: the anti-lost screw attaching/detaching apparatus of one of the present utility model, comprise screw, upper shell and upper shell, described upper shell is provided with groove, the bottom of groove offers via hole, described upper shell is arranged at below the groove of upper shell, lower house is inverted T font, lower house is provided with longitudinal container cavity, and container cavity comprises the thread cavity below the cavity of epimere and cavity; Described screw passes from via hole and inserts container cavity.
Further, described screw comprises the threaded portion below the polished rod portion of upper semisection and polished rod portion, the diameter in polished rod portion is greater than the diameter of via hole and is less than the diameter of threaded portion, adopt such structural design, can ensure that the polished rod portion of screw can be free to slide through after via hole on upper shell, and upper shell can not slided in threaded portion, namely ensure that screw can not be lost.
After ensureing screw disassembling, the threaded portion of screw can enter in cavity, and then upper shell is separated with lower house, and the length of described threaded portion is less than the length of thread cavity.
Beneficial effect: the utility model in use, do not need screw to take out completely, namely need not take out in product completely, stay on product and can open upper shell and lower house, can be absolute prevent screw loss in use, and then reduce the maintenance of user and use cost.

Fig. 1 is the structural representation of the utility model when assembling;
Fig. 2 is the structural representation of the utility model when taking apart;
Fig. 3 is the structural representation of screw in the utility model.
Detailed description of the invention
Below technical solutions of the utility model are described in detail, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1 to Figure 3, the anti-lost screw attaching/detaching apparatus of one of the present utility model, comprise screw 4, upper shell 2 and upper shell 2, upper shell 2 is provided with groove 11, the bottom of groove 11 offers via hole 12, and upper shell 2 is arranged at below the groove 11 of upper shell 2, and lower house 1 is in inverted T font, lower house 1 is provided with longitudinal container cavity 3, container cavity 3 comprises the thread cavity 32 below the cavity 31 of epimere and cavity 31; Screw 4 passes from via hole 12 and inserts container cavity 3.
Screw 4 in the present embodiment comprises the threaded portion 42 below the polished rod portion 41 of upper semisection and polished rod portion 41, and the diameter in polished rod portion 41 is greater than the diameter of via hole 12 and is less than the diameter of threaded portion 42; And the length of threaded portion 42 is less than the length of thread cavity 32.
The utility model in use, need not take out screw 4 but indwelling can not be lost on upper shell 2 completely, reduces maintenance and the use cost of user greatly.
In actual use, after being tightened by screw 4, the threaded portion 42 of screw 4 enters the thread cavity 32 of lower house 1, and now upper shell 2 is fixedly connected with lower house 1; And after being unscrewed by screw 4, the threaded portion 42 of screw 4 enters in the cavity 31 of lower house 1, now upper shell 2 and lower house 1 can separate.
