Description

  The present invention relates to an anti-slipping and sling fixing device, and more particularly, a fixing device that has a single fitting and chaining, and has multiple functions such as quick mounting, fitting, fast chaining and anti-skid removal. The present invention relates to an anti-slip / de-sling fixture.

To date, there is a sling fixture (A1) designed and provided by the inventor as shown in FIG. This type of fixing device (A1) mainly forms a fitting effect between the slings (A2) in such a manner that the tension spring (A13) assists the steel balls (A15) and converges. Therefore, when the fixing device (A1) is in a normal state, the steel ball (A15) in the fixing device (A1) is in a state where it is permanently fitted to the sling with the three converging walls by the tension action of the elastic spring (A13). Form. The structure of this type of fixing device (A1) mainly consists of a steel on the front lid (A11), fixing device body (A12), tension spring (A13), shift shaft center (A14) and shift shaft center (A14). It consists of a sphere (A15). The front lid (A11) is screwed with the fixing device main body (A12), and the inner edge wall of the front lid (A11) exhibits a trumpet converging wall (A111), and a converging surface provided by the shift shaft center (A14). Corresponding to (A141) and the steel ball (A15) arranged in front of the axial center, it is completely restricted in the fixing body (A12). As a result, the front cover (A11), the steel ball (A15), and the shift shaft center (A14) are separated by a tension spring (A13) installed forward from the shaft center (A14). From the shift operation, the steel ball (A15) to be installed generates a convergent fit and release of the sling (A2) to achieve the localization and release adjustment function.

  The known fixing device (A1) has only a fitting ability from the standpoint of merit, and has no safety chain effect. Once the tension of the spring (A13) is insufficient, or after touching the shift axis (A14) (retracting inward), the suspended object will immediately slip out and affect the safety of personnel. It also affects the value of hanging objects such as paintings and fixtures.

An object of the present invention is to provide a structural design of a fixing device, and in particular, to provide an anti-slipping and sling fixing device and to solve the above-mentioned problems.

  The anti-skid / slipping fixture of the present invention comprises a brake and a chain coupler. The brake engages and releases the sling. The chainer will fix and release the fixator.

  This fixture completely eliminates false touches and dislocations, and solves the problem of suspension and slipping.

  As shown in FIGS. 2 and 3, the overall structure of the anti-skid / slipping fixture (10) of the present invention is divided into a brake (1) and a chain coupler (2). Both the brake (1) and the chain coupler (2) maintain the connection relationship and constitute the fixing device (10). The brake (1) mainly comprises a front lid (11), a tension spring (12), a shift shaft center (13), a brake body (14), and a steel ball (15) on the soft shaft center (13). The chain coupler (2) is constituted by a screw element and maintains a connection relationship with the brake (1) described above.

  Referring to FIG. 4, the front lid (11) in the brake (1) is installed at a screw opening (141) opened forward of the brake body (14) by the screw portion (111), and the front lid ( 11) has a through hole (112) and an edge (113) installed forward, and the sling (3) passes through the through hole (112), and the edge (113) passes through the tension spring (12). In contact with each other, the shift shaft center (13) in the brake body (14) is directed, and is disposed on the steel ball 15 on the shift shaft center (13) to be in a state of compression. Next, the brake body (14) is forwardly screwed by the front lid (11), and the inner edge wall has a converging surface (142), and a shift shaft (13) and a steel ball (15 ), The tail end (143) passes through the threaded end (131) of the shift shaft center (13) and is connected to the chain combiner (2). In addition, the shift shaft center (13) is installed inside the brake body (14), the front end is limited by the tension of the tension spring (12), and the bearing hole (132) of the steel ball (15) is positioned at the front stage position. In particular, each bearing hole (132) and steel ball (15) have a certain tolerance relationship with the inner edge of the main body and the inner diameter of the front lid (11), and each steel ball (15) In addition to performing the tolerance operation in the bearing hole (132), the steel ball (15) is prevented from being detached.

  As shown in FIG. 4, the shift shaft (13) itself is hollow, penetrates the sling (3), and the brake ball (14) is formed by the steel ball (15) on each bearing hole (132). ) After corresponding to the converging surface (142) of the inner edge, a fitting effect is generated. Next, the rearward portion of the shift shaft center (13) is provided with a screwing end (131), and the screwing end (131) passes through the tail end port (143) of the main body, and then is directly connected to the chain coupler ( 2) and generate a screwing merit. The details of the structure are obtained by processing a wide-end retaining edge (133) at the screwing end (131) port to form a coupling structure that prevents the chain coupler (2) from being detached. In addition, the coupling device (2) of the present invention itself is a screw element, and has a screw pattern (21) adapted to the screwing end (131) of the shift shaft, and the restriction hole (22) It is limited to the wide-mouth stop edge (133) of the shaft center, and the screwing end (131) of the shift shaft center is not detached from the chain coupler (2).

  As shown in FIG. 4, in the brake (1) of the present invention, in the normal state, the tension spring (15) corresponds to the convergent surface (142), and each steel ball (15) is inserted into the sling (3). To achieve a basic mating effect. At this time, the joining portion (2) and the screwing end (131) of the shift shaft center are joined, and both the joining portion (2) and the brake (14) form a chained state. Referring to FIGS. 1 and 6, in particular, the addition of this chaining function provides a strong attracting force to the shift shaft (13), which is converted to a stronger fitting force, and the brake (1) Ensuring the fitting ability, the shift axis (13) moves in, prevents the risk of release, and ensures safety.

  Referring to FIGS. 5 and 7, when released, the brake (1) loosens the chain coupler (2) and pushes the shift shaft center (13) to be connected to release the steel ball (15) on the shaft center (13). However, a release gap is formed between the convergent surfaces (142), the sling (3) at this time is loosened, and the height of the fixing device (10) can be adjusted.

It is sectional drawing of a well-known fixing device. 1 is a three-dimensional external view according to a preferred embodiment of the present invention. It is an exploded structure figure of each element of the present invention. It is a whole structure figure of the fitting state of the present invention. It is the whole structure figure of the release state of this invention. It is a whole structure figure of operation control operation of the present invention. It is a three-dimensional external view of the present invention.
