Description

High strength channel-section steel hasp

Technical Field

The utility model relates to a pre-buried groove hasp technical field specifically is a high strength channel-section steel hasp.

Background

At present, most of electromechanical circuits in a building system need to take shockproof and shock-absorbing measures, a lock catch is a key part frequently used in the shockproof and shock-absorbing measures, and the lock catch is mostly matched with U-shaped channel steel for use.

The lock catch is mostly matched with U-shaped channel steel for use, and has the main advantages that 1, the channel steel and parts realize modularized/standardized production, so that the production efficiency can be improved, and the labor cost can be reduced; 2. the finished product support system is convenient to install and maintain (parts are easy to purchase), and has the advantages of shortening the construction period, reducing the maintenance time and the like; 3. the device can be flexibly assembled into various types meeting production requirements through the assembly of different accessories, and various construction environments are met.

However, the supporting block and the screw rod in the lock catch on the market are generally integrally formed, and the integrally formed screw rod is easy to break off when stressed and low in strength.

Detailed Description

The embodiment of the utility model provides a high strength channel-section steel hasp, as shown in fig. 1-6, install on channel-section steel 9, channel-section steel 9 is pre-buried on the building in advance. Including rectangular supporting shoe 1, screw rod 3, gasket 4 and nut 5, seted up card hole 2 on the supporting shoe 1, the internal diameter of card hole 2 slightly is less than the external diameter of screw rod 3, and screw rod 3 passes through

card hole

2 and 1 joint of supporting shoe.

As shown in fig. 3, in a specific pressing process, one end of the screw rod 3 needs to be clamped into the clamping hole 2 by means of a stamping die, and the end of the screw rod 3 is folded outwards under the stamping of the stamping die to be engaged with the supporting block 1.

As shown in fig. 4, the washer 4 is sleeved on the screw rod 3 and corresponds to the channel steel 9, and the washer 4 can increase the contact area with the surface of the channel steel 9 and increase the strength. The nut 5 is in threaded connection with the screw rod 3, and the nut 5 is used for integrally fixing the lock catch on the channel steel 9.

Set up card hole 2 on supporting shoe 1, with the horizontal joint of screw rod 3 in supporting shoe 1, then make the tip of screw rod 3 turn over outwards and roll over with supporting shoe 1 interlock under stamping die's punching press, make the joint strength between screw rod 3 and the supporting shoe 1 compare integrated into one piece higher, the durability is high, long-lived.

The inner wall of the clamping hole 2 is vertically provided with a plurality of clamping strips 6, and the clamping strips 6 are circumferentially arranged around the inner wall of the clamping hole 2. Through setting up card strip 6, make 3 card of screw rod go into difficult rotations behind the card hole 2, greatly increased the joint strength of screw rod 3 with supporting shoe 1.

The support block 1 is in the shape of a parallelogram. The design of parallelogram can increase horizontal total contact length, can greatly increased the joint strength between supporting shoe 1 and the channel-section steel 9.

Tooth grooves 7 corresponding to the channel steel 9 are arranged on two sides of the supporting block 1. The tooth grooves 7 are used for being clamped into corresponding grooves in the channel steel 9.

The top of the supporting block 1 is provided with a plurality of resistance-increasing strips 8 corresponding to the channel steel 9, and the height of the resistance-increasing strips 8 is lower than the tooth grooves 7. The resistance between the supporting block 1 and the channel steel 9 can be greatly increased by the resistance increasing strip 8, so that the sliding is prevented.

When the shackle is assembled, as shown in fig. 5, the parallelogram support block 1 is vertically inserted into the channel steel 9. As shown in fig. 6, the support block 1 is then turned through 90 ° and finally the screw cap 5 is tightened.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
